Title: Improvements in or relating to methods of manufacturing permanent magnets of the kind employed in electric metering apparatus
IPC: H01F1/04
Filed: 1945-12-28
Abstract: In a method of manufacturing a permanent magnet of the kind used in electric metering devices, a loop casting of an alloy of coercivity greater than 200 oersteds is heated by a high frequency induction heating coil to a temperature above its Curie temperature allowed to cool in the presence of a circular magnetic field to below its Curie point and then has a radial portion removed to provide and air gap. The circular magnetic field may be obtained by disposing the casting on a conductor rod of circular section which is connected to a source of direct or alternating current, and the induction coil which may be one and a half times the length of the casting is arranged round both casting and conductor.  The magnetic field produced by the conductor is maintained from the time of switching on the heating core current, when the loop casting has a temperature of 1200 DEG C., until the casting has a temperature of 500 DEG C.  The magnetic alloy may have the following constituents C-.06 per cent, Ni-11.5 per cent, Al-8 per cent, Cu-4 per cent, Co-21 per cent, the remainder being iron.

Abstract: 1529604 Television systems SANYO ELECTRIC CO Ltd 23 Aug 1976 [25 Aug 1975 9 Feb 1976] 35038/76 Heading H4F A jitter correction circuit JCC, Fig. 1, corrects for phase differences between the video signal from a recording apparatus VRA and the signal from the horizontal sync. automatic frequency control 8 in a television receiver TV and is adjustable in acccordance with the phase-frequency characteristic of the a.f.c. 8. The circuit includes a circuit 3 for phase-modulating horizontal sync. pulses which are separated (1) from the video signal. The phasemodulated sync. pulses are inserted (4) in the video in place of the separated pulses. In order to adjust the circuit a test signal is applied to it instead of the video signal. Generator PSG provides the test signal, which includes a horizontal sync. pulse and a marker pulse in each line. The sync. pulses in successive fields have periods which are respectively greater and less than the normal sync. pulse period. As a result two marker lines appear on the receiver screen. By adjusting (14A, 14B) the amplitude and phase of a signal from the jitter detector 13 representing phase jitter in the separated sync. pulses the lines are moved until they are as close as possible.

Abstract: 857,523. Mixing gases with liquids in flow. CLARKE-BUILT Ltd. Nov. 5, 1958 [Nov. 12, 1957], No. 35297/57. Class 86 [Also in Group XXVI] A device for mixing a gas with a liquid or semi-liquid and particularly for aerating beverages and sweet confections or producing plastic foams consists of two internally meshing gear pumps in a common housing. Liquid is admitted by port 15 to the pump chamber 16 whence it is transferred by the passage 12 to the chamber 17 of a second pump and discharged through port 18. The pumps are connected by gears 39, 40 (Fig. 2, not shown) so that the second pump rotates at the higher speed, creating a reduced pressure in the passage 12 and inducing gas thereinto through the valve 49 and port 14. The highly turbulent flow in the duct 12 and pump chamber 17 causes the gas to become entrained in the liquid. The proportion of gas to liquid is constant for a given pump speed and can be altered by changing the setting of the valve 49. The clearance of the pumps is adjustable in an axial direction during operation by rotation of a squared stud as at 48 rotating a pinion 46 meshing with the toothed periphery 45 (Fig. 2, not shown), of a threaded collar retaining the pump rotor thrust bearing.

Abstract: 488,112. Wireless receiving systems. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and KEALL, O. E. Dec. 31, 1936, No. 35886. [Class 40 (v)] Relates to receivers employing automatic frequency control with an asymmetrical characteristic, i.e. to systems in which the automatic control action is different when the receiver is off tune in one direction from when it is off tune in the other direction, a relay being employed to change the connections to make manual tuning possible in either direction. According to the invention a condenser C is connected to a variable source of potential, such as a cell T and potentiometer P, the variable element of which is ganged with the tuning condenser of the receiver. The charging current of the condenser C, when the slider S is moved, operates a meter type relay R, the contacts RC of which reverse the excitation of the winding R1 of a polarized relay the contacts (not shown) of which effect the necessary changes. The meter type relay may be employed directly to change the connections ; and in a modification, Fig. 3 (not shown), coil R is replaced by a resistance, the voltage across which is applied to the grid of a valve in whose anode circuit the polarized relay is connected.

Abstract: 1,059,683. Dispensing egg boxes from a stack. KEYES FIBRE CO. Sept. 4, 1964 [Jan. 30, 1964; June 5, 1964], No. 36262/64. Heading B8S. Egg boxes 84, Fig. 4, are discharged one at a time from the bottom of a stack by the co-ordinating movements of retaining finger 122, stripping finger 136, sensing means 102, and support means 78. The cycle of operations begins as shown in Fig. 4, the stack being supported by support means 78. Retaining finger 122 is moved leftwards to contact the rim 86 of the next lowermost egg box. Supporting finger 136 is likewise moved leftwards in between the flanges of the bottom and the next bottom egg box. Sensing means 102 and support means 78 are moved downwards and swung outwards out of engagement with the bottom box. Then, with the stack of boxes resting on retaining finger 122 stripping finger 136 moves downwards to dislodge and discharge the bottom box. The cycle repeats. Figs. 1a and 2 (not shown).-The cycle of movement is effected by operating bar 72 which moves up and down, the movement being effected by solenoid 36 operating through lever 50 pivoted at 54. Bar 72 in its downward movement carries with it U-shaped bar 156 being connected thereto by shaft 164, spring 170, and sleeve 166 fixed to bar 72. Cam 160 carried by U-bar 156 engages follower 124 to move retaining finger 122, relative to block 118, inwards between the flanges of the bottom box and the next bottom box. Likewise, cam 158 of the U-bar 156 engages follower 138 to move stripping finger 136 also between the flanges of the bottom and next bottom boxes. Next, sleeve 110 carried by the descending bar 72 engages shaft 105 by means of pin and slot connection 106, 108 and pin and cam connection 114, 116 to cause the shaft 105 to rotate and also to move longitudinally downwards so that sensing means 102 which is carried by shaft 105 is moved outwards from the rim of the lowermost box. Likewise, sleeve 98 carried by the descending bar 72 moves shaft 88 downwards whilst rotating it by the pin and slot engagement 94, 96 and by the pin and cam engagement 90 and 92, so that support means 78 carried by shaft 88 is moved out from under the bottom box. The stack is now supported by finger 122. At this stage descending bar 72 engages the top 154 of shaft 146 to move block 132 downwards together with shaft 142 secured to block 132 so that stripping finger 136 which is carried by block 132 moves downwards relative to block 118 to engage the flange of the bottom box and to push it downwards and discharge it. In this way the bottom box is discharged positively in spite of being jammed in the stack. The retaining finger and stripping finger may be pivoted bars of differing shapes. The discharge may be effected by a plurality of the sets of retaining, stripping, sensing, and support means.
