Patent GB-1103536-A (GB)
Abstract: 1,103,536. Hall effect devices. CANADAIR Ltd. 1 Aug., 1966 [27 April, 1966], No. 34482/66. Heading H1K. [Also in Divisions G1 and H3] A Hall plate 13 is mounted in the air gap between a pair of aligned high permeability magnetic field concentrating rods 18 and 19, and the dimensions of the air gap are arranged to vary with temperature in such. manner that the effective permeability of the magnetic system has a temperature-dependent variation which just compensates for the temperature dependence of the Hall plate output. The Hall plate output varies with temperature because both its resistance and its Hal coefficient vary. If the temperature range in use is small, the air gap variation may provide compensation for both effects. But for larger ranges, it is envisaged that the air gap variation will compensate for the Hall coefficient change alone, the resistance change being compensated by negative temperature coefficient resistance in the external circuitry. Fig. 3 (not shown), depicts suitable circuitry incorporating such resistance (see Divisions G1 and H3). The rods 18, 19 are mounted in respective sleeves 20, 21 which can slide in the tubular housing 10. The Hall plate 13 is carried by a centrally apertured mounting block 14 which is also free to slide in the housing 10. The spacing between the adjacent ends of the rods 18, 19 is defined by spacer tubes 16, 17, each ' of which abuts at one end the block 14 and at the other a flange 20a or 21a on one of the sleeves 20, 21. It is arranged that the coefficient of expansion of the sleeves 20, 21 i exceeds that of the spacers 16 17 so that the gap between the rods 18 and 19 decreases with increasing temperature and so provides the required correction. The housing is closed at one end by a cap 11 carrying the plug 34 of a spherical plug-andsocket bearing in which the device is designed to be mounted. The other end is closed by a cap 12 which incorporates an electrical plug connector 31.

Abstract: 1,225,772. Automatic frequency control. GENERAL ELECTRIC CO. Ltd. 22 July, 1968 [20 April, 1967], No. 18330/67. Heading H3A. The phase lock loop maintains the frequency of the signal at output terminal 9 at the same frequency as the reference signal at 18. The output at 9 is derived from a master oscillator, at terminal 1, by the non-integral dividing circuit 3, 6, 7. The bi-stable circuit, 4, provides a "1 " or " 0 " output according as the synthesized signal is too high or too low, that is, according as its phase is advanced or retarded with respect to the reference frequency signal. The condition of the enabled or disabled gate 5, determined by the output of 4, controls the action of dividers 6 and 7 upon divider 3, thereby correcting the frequency of the signal at 9. In a modification, the input 18 is replaced by a speech signal, which after passage through a delta-sigma modulator, controls the gate 5, as in Fig. 1. In this case the frequency modulation of the output pulse train represents the input wave form.

Abstract: 1,227,251. Bailers. COMSTOCK & WESCOTT Inc. 15 July, 1968 [31 July, 1967], No. 33703/68. Heading F4A. Liquid in a coil 14 is vaporized by heater means 4 which heats up heat-storage material 13, e.g. an alkali hydroxide, in contact with the tube, the heater being controlled by means responsive to the temperature of the material 13. In the boiler shown in Fig. 1 the products from a burner 19 pass through tubes 7 to heat sodium hydroxide 13, the tube 14 being supplied with water at substantially constant pressure by a pump 16 with by-pass valve 18. Superheated steam at the coil outlet 9 is passed to a turbine or steam engine 12. The burner 19 is controlled by a thermostat 22 buried in the material 13, the fuel valve 21 being closed at a temperature of 650 F. and opened when the temperature drops to 625 F. During average operating conditions the heating rate equals the demand and the temperature of material 13 remains constant. If the demand decreases, the excess heat is stored in material 13 until burner 19 is shut off; if the demand increases, heat from material 13 supplements that from burner 19. The temperature of material 13 drops but sufficient material is present to meet the maximum demand without the temperature dropping below the melting point, 605 F., of the sodium hydroxide. In Fig. 3 the boiler casing is divided by partition 28 into upper and lower compartments 26, 27 containing respectively lithium hydroxide (melting point 880 F.) and sodium hydroxide. The burner 19b is controlled by a thermostat 22b in the lower compartment which cuts the burner off and restarts it at temperatures of 950 F. and 700 F., respectively. The maximum temperature of the lithium hydroxide is controlled by a thermostat 32 controlling by-pass valves in the tubes 7b to divert the flue gases through a passage 6c in the partition 28 when the maximum temperature of 950 F. is reached and to reopen the valves when the temperature of the LiOH drops to 900 F.

Abstract: 1,227,899. Switchgear structures. WESTINGHOUSE ELECTRIC CORP. 3 Nov., 1969 [27 Nov., 1968], No. 53792/69. Heading H1N. A circuit breaker 7 is withdrawable from isolating contacts 21 by a camming action between a roller 41 and a slot in a fixed part 43. In the withdrawn position a lever 71 can be moved by a lock 81 to prevent roller 41 entering the slot so that the breaker may not be inserted; in this last position, only, the key may be removed from lock 81. Thus if only one key is provided, only one of a group of circuit breakers (not shown) in adjacent cubicles may be inserted.

Abstract: 1,228,329. Preventing freezing of moisture in compressed air lines. ROBERT BOSCH G.m.b.H. 12 Nov., 1969 [13 Nov., 1968], No. 55266/69. Heading B1R. [Also in Division Fl] A pump for injecting anti-freeze into a compressed air line 26 comprises a pumping piston 6 reciprocable in a cylinder 5 in response to changes of air pressure acting on a motor piston 16 connected by a rod 7 to the pumping piston 6. Air pressure for actuating the motor piston 16 may be in the form of a fluctuating pressure supplied to a chamber 11 above the piston 16, or the pressure in the chamber 11 may be substantially constant, the fluctuating pressure then being applied to a chamber 18 below the piston 16. Anti-freeze enters the cylinder 5 through a pivot 4 connected to a reservoir 3 and is discharged past a valve 9 loaded by a spring 10. A stop 21 is adjustable to vary the stroke.
