[Class 40 (ii)] A magnetic recording and reproducing head 10 comprises a paramagnetic plate 19 having a pair of holes 21, 22 therein, and slots 23, 24 extending between the holes and an edge 20 of the plate, two coils 12, 13 each extending through one of the holes and over the slot associated therewith, one of the coils, 12, being connected to a source of H.F alternating current 14, and the other, 13, being connected to a source of audio-frequency current such as the amplifier 16, the edge 20 of the plate defining a path along which a wire 11, of high magnetic retentivity is arranged to travel. The crowned edge 20 of the plate 19 is provided with a flaring groove 29 with diverging wall portions 30, 31, Fig. 3, and with a further groove 32 having a greater radius of curvature than the groove 29 so that any enlargement on the wire will cause it to ride up out of the inner groove 32 thus preventing jamming. The plate 19 is retained between two plates 33, 34 of insulating material, each having holes 35, 36 slightly smaller than the holes 21, 22 and concentric therewith. The upper edge 37 of each insulating plate is notched as at 38, 39 to receive the coils. The wire travels in the direction indicated in Fig. 1 and is demagnetized by passing through the highly concentrated field set up by the coil 12 between the polar portions 25, 26. The record is then made as the wire passes through a magnetic field which is the resultant of the A.F. exciting current in the coil 13 and the stray field in the vicinity of the polar portions 27, 28 due to the H.F. current in the coil 12. Reproduction takes place by reversal of the direction of travel.

Title: An improved method and means for jointing thermoplastic synthetic resin pipes, pipe fittings and the like
IPC: B29C65/02
Filed: 1956-04-16
Abstract: 796,304. Moulding pipe ends prior to jointing. YOUTHED, S. E. Nov. 8, 1956 -[April 16, 1956], No. 11562/56. Class 87(2). [Also in Group XXVIII] Pipes, pipe fittings &c. made of thermoplastic synthetic resin material, e.g., polyethylene are joined by separately melting the inner annular surface on the end 2 of one pipe and the outer surface of a. spigot 1 on the end of the other pipe and then forcing the parts together, the outer wall of the socket being subjected to a radial compressive force, e.g., by a band 10, so as to press the parts together during cooling. Apparatus used, Fig. 1, comprises a steel tool 3 having a collar 4 which is chamfered at 6 to provide a lead for the spigot 1, and a plug 5 which fits in the socket 2, the ends having sizing lips 7, 7a respectively. Behind the lip 7 the collar is internally recessed at 8, the end of the recess being the same diameter as the lip 7, and then has a frusto-conical wall 9 which inwardly converges away from the collar mouth at 45 degrees. The external surface of the plug part is shaped similarly in a reverse manner, the recess 8a being followed by an outwardly converging wall 9a. To form the joint, the band 10 is fitted round the socket 2, the tool 3 is heated by a blow lamp &c. to a temperature between 350‹C. and 500‹C. and the socket 2 is applied to the plug 5 and pushed home until the rim reaches the stop 9a, and as it passes over the heated lip 7a the inner wall surface is melted, excess material in molten form scraped back so that the socket becomes accurately sized. The spigot 1 is then introduced into the collar 4 where similar melting and sizing takes place. The spigot and socket are left engaged for a pre-determined period, further heat being given by radiation from the recesses 8, 8a, and the pipe ends soften and take up the form shown in Fig. 2. They are then withdrawn, the lips 7, 7a serving to scrape the surfaces to remove oxidized material, and mated, the ring 10 exerting pressure on the joint until the heat dissipates. The stops 9, 9a serve to keep the unheated edges of the spigot and socket out of contact with the tool body during heating so as to avoid burrs and provide a smooth bore after mating, Fig. 4. In modifications the plug end of the tool is solid and in Fig. 5 (not shown), a heat retaining ring is applied to the outer wall of the collar. Fig. 6 (not shown) illustrates the use of a circular heating element over the heat retaining ring. The tool may be supported on a stand, and in further modifications has the collar and plug parts separately mounted and electrically heated. The sizing lips 7, 7a and the recessed radiant heat surfaces may be lined, e.g., with copper or phosphor bronze, and made detachable.

Title: Improvements relating to magnetic transmissions
Inventor: BOMYER LEONARD
IPC: G01F23/38
Filed: 1951-05-18
Abstract: 707,408. Magnetic couplings. TRIST & CO., Ltd., R. May 16, 1952, [May 18, 1951], No. 11695/51. Class 35 A magnetic coupling device to control boiler water level comprises a driving magnet 14 pivotally mounted on one side of a non-magnetic wall 28 and two driven magnets 36, 38 pivotally mounted on the other side of the wall 28, both driven magnets 36, 38 being successively repelled by the magnet 14. The driven magnets 36, 38 carry two-way mercury switches 52, 52' respectively. The feed water is cut off when the water level is as shown in Fig. 1 and, as the water falls from this level, the pole 34 of the magnet 38 snaps downwards (Fig. 5) so changing over the switch 52<SP>1</SP>. This switch controls a feed pump. If the water level continues to fall, the pole 30 of the driving magnet 14 reaches the position shown in Fig. 6 and the pole 32 of the upper driven magnet 36 snaps downwards and so the switch 52 changes over. This switch controls a low water alarm. As the water rises again the reverse operation occurs. The invention describes various modifications concerning the location, size and relative movements of the driving and driven magnets. For instance, if the driven magnets are to snap over in quick succession they have to be staggered and the driving magnet 68, Fig. 8 (not shown), have to be made of greater width than the two driven magnets. Again, as shown in Fig. 10 (not shown), the arcs of travel of the various poles need not be in parallel planes. The driven magnets may, if required, be arranged to travel together in one direction of the movement of the driving magnet. The magnets need not be bar magnets; they can have horseshoe shape. If a large number of switches are to be controlled by a single member such as a float, there may be provided three or more driven magnets each mounted similarly with a driven pole moving through a different arc.
