Title: Improvements in methods of manufacturing magnetically anisotropic permanent magnets having crystalline structures
IPC: H01F1/04
Filed: 1960-12-14
Abstract: <PICT:0974494/C6-C7/1> A magnetically anisotropic permanent magnet is manufactured from a permanent magnet alloy casting by inserting the casting 1, enclosed in a sheath of non-magnetic heat resistant material, into the turns of a high frequency magnetic induction coil 2, e.g. of water-cooled copper pipe, moving the casting relative to the coil, such as by lowering from a cord 4 at a rate of 2 mm./sec., so as to locally remelt one zone after another, e.g. to 1450  DEG C., thus destroying the original crystal structure and subsequently quenching each zone, e.g. at a distance h of 10 mm. from the re-molten zone, by contact with a cooling fluid such as air or water in a tank 3 so as to recrystallize the structure of the casting in the direction parallel with the magnetic lines of force induced by the coil.  Several pieces of permanent magnetic material enclosed in the sheath may be subjected to the above successive heating and quenching treatment to obtain a single bar magnet which may be cut into several pieces. A suitable alloy consists of 13-40% Co, 10-20% Ni, 6-13% Al, 0-9% Cu, 0-8% Ti, 0-3% Si and balance Fe.

Filed: 1974-10-03
Abstract: 1479946 Pressure gauges SOFILTRA SOC INDUSTRIELLE DE FILTRATION 3 Oct 1974 [3 Oct 1973] 43028/74 Heading G1L [Also in Division H1] A device for indicating blockage of a filter, e.g. of an I.C. engine air intake, and of the kind having a part-transparent housing and an indicator attached to a diaphragm, the indicator being moved into view through the transparent portion by movement of the diaphragm in response to an excessive drop in pressure at the filter outlet, includes switch means operated by the diaphragm to give a remote indication of blockage. Locking means prevents return of the diaphragm and thus switching off until the device is reset. The diaphragm 5 in the arrangement shown, divides the housing into compartments 6a, 6b, the former being connected to the filter outlet 10 and the latter to atmosphere. An indicator 15 is attached to the diaphragm and, when a pressure drop expands the bellows of the latter, is visible through the transparent wall 2a to denote blockage. At the same time contacts 20, 21 of a switch are closed to give the remote signal. A hairpin element 31 is drawn by the diaphragm movement through an aperture 4 in a fixed partition 3 until rachet teeth 34, 35 on the arms 32a, 33a engage beneath the partition, locking the indicator and the switch in the blockage signalling position. The diaphragm is released by pressing down a member 38 having an aperture 40 which fits over the upper ends of the arms to draw them together to free the teeth 34, 35. A spring 16 then returns the diaphragm, opens the switch and causes the indicator to enter the opaque part of the housing.

Title: Apparatus for detecting the end of a chromatographic signal
IPC: G01N30/86
Filed: 1971-09-15
Abstract: 1343362 Chromatograph apparatus INSTRUMENTATION SPECIALTIES CO 15 Sept 1971 [17 Nov 1970] 43062/71 Heading G4H [Also in Division G1] In gas or liquid chromatograph apparatus a logic circuit 18 develops a signal on lead 22 or lead 34 to enable a counter 28 to count clock pulses from a source 16 positively or negatively in dependence on whether the magnitude of the slope of the chromatograph output is greater or less than a predetermined (near zero) level. When the count reaches zero when the counter is counting down a processor 12 is enabled to readjust or otherwise utilize the chromatograph signal. Since the counter is incremented during peaks in the chromatograph and decremented during the base line signal the apparatus ensures that the adjustment only occurs during non- slope times on the base line. The logic circuitry 18 comprises a pair of bistables comprising NAND gates 80, 82, 96, 98 the output signals from gate 80 to 98 being "1" when a positive or negative slope exists to provide (1) a "1" signal of either lead 22 or lead 34 and (2) at the output of bi-stable 110 a "1" signal on lead 24 or 26 in dependence on whether the slope is positive or negative, this signal being held during a subsequent no-slope signal. If a positive slope is immediately followed by a negative slope counter 28 is reset by the output of a gate 42 at the top of the peak. This enables the base line to be determined more quickly. Bi-stables 62, 64, 66 are connected to detect peaks of small duration resulting from noise and prevent readout of the processor during these various peaks. The counter 28 may be replaced by a capacitor charged and discharged respectively during slope and no-slope signals.

Abstract: 971,828. Rotary conveyers; labelling machines. MOLINS MACHINE CO. Ltd., and F. SOUTHCOTT. Dec. 13, 1962 [Dec. 13, 1961]. No. 44645/61. Headings B8A and B8F. [Also in Division B6] Labels are separated one at a time from a magazine 6, fed past a gluing roller 51, and applied to a packet P, by a rotating suction drum 1. The suction drum 1 is provided with suction stations 2-5, each comprising two pairs of suction ports. Each pair of suction ports is connected to a transverse passageway 44 by radial bores 41, 43. The passageways extend through a gear-wheel 27 secured to the drum and the two passageways associated with each suction station co-operate with one of four arcuate channels 36-39 in the face of a housing 29. The channels 36-39 extend over 270 degrees and are connected to a source of suction via valves 13-16, respectively. The valves are mounted in the upper part of the housing 29, which is stationary and urged against the gear-wheel by the springs 30. The suction ports are vented to the atmosphere, to assist in depositing the label at a poisition P, by means of apertures 47-50 in the housing 29. Each valve sleeve is apertured at 17 to communicate with a manifold 12, connected to a source of suction by tube 10. The lower end of each sleeve forms a seat 18 for a ball 19. The seat 18 and ball 19 are adapted to permit a small air leak through the valve when closed. A spring 20 normally holds the ball away from the seat and in engagement with a ring 24. The latter is slotted at 25 to allow the passage of air from below to above the ball. In the event of a suction station failing to pick-up a label from the magazine 6, the suction ports remain open to the atmosphere and the ball is urged into engagement with the seat 18 to close the valve by means at a greater air pressure on the underside of the ball. Movement of the ball may close an electrical circuit to give a warning signal. For example, the ball may have an arm, Fig. 3 (not shown), passing through a rubber bush in an opening in a valve wall, which engages the operating lever of a switch. Alternatively, the valve seat is formed of metal and in two parts separated by insulating material, the two parts forming terminals in an electrical circuit. The ball is made from metal so that on moving into the seat 18, it bridges the two parts to close the circuit. A stationary strip 56 located in a groove in the drum surface, extends at a tangent to the drum at the position P, to strip the label from the drum. Specification 942,830 is referred to.
