The magnet between the poles of which the rectangular signal coil moves is built up of a number of thin flat horseshoe-shaped permanent magnets of a special quality of steel, and is provided with adjustable pole pieces.
By the automatic curb sender the cable is put to one or the other pole of the battery and then to the reverse pole for definite proportionate times during u b c 0 'c' C p t e a n i m e r rn e ll i a.

The stop a of the key K is connected through a switch S with one pole of the battery B, and the stop b in the usual way with the other pole.
In ordinary hand-sending the Au c curb end of the cable is put to one or the other pole of the ti .
At the sending station one battery was to have its positive pole connected to the earth and its negative pole to an insulated condenser.
It was also found that comparatively small magnets were sufficient, and that there was no particular virtue in the closed circuit and electromagnet, but that a small permanent magnet having one pole in contact with FIG.
- Double Pole Receiver.
M and M' are two permanent magnets; P and P' are soft iron pole-pieces upon which are placed the electromagnet coils C and C'; D is the diaphragm; I is a soft iron distance piece placed between the magnets at the end remote from the diaphragm; B is the brass body of the instrument, over which is placed a thin ebonite shell S.
The endoderm of the planula now acquires a cavity, and at the narrower pole a mouth is formed, giving rise to the primary siphon.
The planula develops, on the whole, in a similar manner, but the ectodermal invagination arises, not at the pole of the planula, but on the side of its broader portion, and gives rise, not to a pneumatophore, but to a nectocalyx, the primary swimming bell or protocodon (" Fallschirm ") which is later thrown off and replaced by secondary swimming bells, metacodons, budded from the coenosarc.
The evolution of mind (the positive pole) proceeds by 1 Kant calls the doctrine of the transmutation of species " a hazardous fancy of the reason."
In the monastic period pharmacy was to a great extent under the control of the religious orders, particularly the Benedictines, who, from coming into contact with the Arabian physicians, devoted themselves to pharmacy, pharmacology and therapeutics; but, as monks were forbidden to shed blood, surgery fell largely into the hands of barbers, so that the class of barber-surgeons came into existence, and the sign of their skill in blood-letting still appears in provincial districts in England in the form of the barber's pole, representing the application of bandages.
At each pole of this spindle figure there often occur fibres radiating in all directions into the cytoplasm, and sometimes a minute granular body, the centrosome, is also found there.
It is continuous round the pole and roughly is bounded by the arctic circle.
The records preserved in each city were examined, topographical information was diligently collected, and the Jesuit fathers checked their triangulation by meridian altitudes of the sun and pole star and by a system of remeasurements.
Academy as part of an investigation with the object of ascertaining the length of the degree near the equator and near the pole respectively so as to determine the figure of the earth.
Arranged with a certain rough radiate symmetry round the north pole, and extending southwards in three unequal arms which taper to points in the south.
(1900) P. 46; Marcel Bertrand, " Deformation tetraedrique de la terre et deplacement du pole," Comptes rendus Acad.
Near the posterior pole of the fundus, but somewhat excentrically placed towards the temporal or outer side, is the fovea centralis, a slight depression in the retina, composed almost entirely of cones, the spot of most acute vision.
Or 162 ft.; this length is also named a pole or perch, the origin of the.
Application being the same as in "rod"; as a measure of area, a rod= a square pole or perch, 304 square yds.
These engines have a pole projecting horizontally in front of them, or are attached to a " polecar " having such a pole.
The method of working is for the pole to be swung out behind a number of wagons; one engine is then started and with its pole pushes the wagons in front of it until their speed is sufficient to carry them over the points, where they are diverted into any desired siding.
For this operation, or its reverse, a man has to go in between the wagons, unless, as in Great Britain, he is provided with a coupling-stick - that is, a pole having a peculiarly shaped hook at one end by which the chain can be caught and thrown on or off the drawbar hook.
For when Yahweh gradually became Israel's local Baal he became worshipped like the old Canaanite deity, and all the sensuous accompaniments of Kedeshoth,' as well as the presence of the asherah or sacred pole, became attached to his cult.
The panegyrics of Aldus Manutius require to be received with some caution, since he was given to exaggerating the merits of his friend, and uses almost the same language about a young Pole named Stanilaus Niegosevski; see John Black's Life of Torquato Tasso, ii.
The four cells first formed are of equal size, and then four smaller cells are formed by division of these four so as to lie at one end of the first four (the pole corresponding to that at which the " directive corpuscles " are extruded and remain).
Its transparency allows us to see even to the pole star, who is the central sun around whom all the heavenly bodies move.
The Mandaean places of worship, being designed only for the priests and their assistants (the worshippers remaining in the forecourt), are excessively small, and very simply furnished; two windows, a door that opens towards the south so that those who enter have their faces turned towards the pole star, a few boards in the corner, and a gabled roof complete the whole structure; there is neither altar nor decoration of any kind.
They have some peculiar deathbed rites: a deacon with some attendants waits upon the dying, and as death approaches administers a bath first of warm and afterwards of cold water; a holy dress, consisting of seven pieces (rasta), is then put on; the feet are directed towards the north and the head turned to the south, so that the body faces the pole star.

18), of stone pillars to the Canaanite Baal, of the Asherah-pole, molten images and the worship of other gods than Yahweh (Ex.
It is excentric as regards the pole and sends tapering extensions towards the south.
Chun and Woltereck, on the other hand, regard the stem as a stolo prolifer arising from the aboral pole, that is to say, from the ex-umbrella, similar to that which grows out from the ex-umbral surface of the embryo of the Narcomedusae and produces buds, a view which is certainly supported by the embryological evidence to be adduced shortly.
The planula becomes elongated and broader towards one pole, at which a pit or invagination of the ectoderm arises.
The outer wall of the capsule is incomplete at one pole, leaving an aperture through which the thread is discharged.
Elec. Eng., 27, p. 938.) It may be explained as follows: - Suppose a battery on shore to have one pole earthed and the other connected to an insulated submarine cable, the distant end of which was also earthed; if now a galvanometer is inserted anywhere in the cable, a current will be found flowing through the cable and returning by various paths through the sea.
The great advantage of the tube anemometer lies in the fact that the exposed part can be mounted on a high pole, and requires no oiling or attention for years; and the registering part can be placed in any convenient position, no matter how far from the external part.
