Title: Improvements in high-altitude oxygen breathing apparatus
IPC: A62B9/02
Filed: 1951-05-08
Abstract: 703,646. High altitude. respiratory appliances. BENDIX AVIATION CORPORATION. May 8, 1951 [May 12, 1950], No. 10834/51. Class 81(2) In an oxygen demand regulator in which a reducing valve controls the inlet and a demand valve passes oxygen from the reducing valve through an injector to the outlet, the movement of the reducing valve towards its open position is assisted by a pressure supplied from the inlet side of the injector. The path, through the regulator, followed by the oxygen from inlet 14, Fig. 2, leads past a stop valve 30 and filter 38 to the reducing valve 48, which is biased to the closed position by a spring 54 and to the open position by a spring 58, adjustable by screw 60, cooperating with an aneroid bellows 56. Oxygen thus flows through the valve into chamber 52 until the pressure therein collapses the bellows 56 sufficiently to close the valve 48. From chamber 52 the oxygen passes to a further chamber 62, Fig 3, normally closed by a demand valve 74. When this is opened, by the user's inspiration, oxygen flows through a nozzle 96, thereby entraining ambient air through ports 100 and passing on to the outlet 166. If the demand exceeds a predetermined minimum the pressure in the space 82 lifts the nozzle body 84 off its seating 94, against a spring 88, and the excess oxygen flows through ports 102, space 106 and ports 108 tothe outlet 16. The pressure in the space 82 is communicated through ducts 114 and 120, Fig. 2, to the interior of the bellows 56, thereby increasing the opening of the reducing valve 48 to increase the flow of oxygen to meet the greater demand. Specification 690,382 is referred to.

Title: Improvements in or relating to Typographic Moulds
Inventor: SCOTT STANLEY GORDON
IPC: B41B11/54
Filed: 1966-03-11
Abstract: 1,179,682. Type moulds. MONOTYPE CORP. Ltd. 28 Feb., 1967 [11 March, 1966], No. 10875/66. Heading B6W. A type mould for type-casting machines has a rectangular base 11 supporting spaced side plates 13a and 13b and side blocks 15 and 16 including hard surfaced inserts 17 and 18 defining the sides of a moulding cavity 35. One end wall of cavity 35 is defined by slidably mounted cross block 21 and the other end wall by blades 19 and 20 slidable between the side blocks. The base of the cavity is formed partially by intermediate plate 14 and partially by gate blocks 23 and 24 attached to the underside of slidably mounted cross block 21, the gate blocks being spaced to provide the upper part 25 of a liquid metal inlet passage to the mould cavity, the lower part 37 of this passage being in base 11. Insert 18 may be of various thicknesses to change the point size of the cast type, the width of the front part of blades 19 and 20 will then be changed correspondingly. Cooling water is fed through base 11, intermediate plate 14, side block 15 and insert 17 close to mould cavity 35, side block 16 and insert 18 close to mould cavity 35. A first further cooling water circuit leads via flexible pipe 30 into lower blade 20 and passes near cavity 35, and a second further cooling water circuit passes through base 11, side plate 12, tube 31, cross block 21, gate blocks 23 and 24 (passing close to hot metal inlet passage 25) and tube 32 to waste. Operation.-The mould is stated to be of use in type-casting machines such as are sold under the Registered Trade Mark " Monotype." A matrix is positioned over cavity 35, hot metal is injected through passages 37 and 25, and solidifies in cavity 35. Cross block 21 is then moved (to the right, Fig. 2), carrying with it blocks 23 and 24, thus simultaneously breaking off the piece of metal left in the upper part of inlet 25 from the moulded type body and opening the end of cavity 35 to allow blades 19 and 20 to move forward and eject the cast type body.

Title: Transistor frequency converter
IPC: H03D7/12
Filed: 1956-04-12
Abstract: 789,428. Transistor frequency converting circuits. HAZELTINE CORPORATION. April 12, 1956 [May 5, 1955], No. 11179/56. Class 40 (6). In a circuit in which a signal input 21 is applied to a transistor 22 associated with a regenerative oscillatory system 50 coupled to the input to produce a beat frequency signal in circuit 12, and in which the regenerative system includes the internal base impedance tending to prevent oscillation, a reactance 42 is provided to compensate the phase shift in the feed-back path thereby maintaining oscillation. The circuit is described as applied to a radio receiver in which an aerial 17 is coupled to a tuned circuit 18, 20 and a coupling coil 21 applies a radio frequency signal between the base 31 and emitter 35 of the transistor, capacitor 42 acting as a by-pass. An inductor 43 in the collector circuit is coupled to tuned circuit 39, 40 which determines the frequency of the local oscillation, a tap on coil 39 being connected to the emitter. The collector current passes to a tap on the inductor of circuit 12 tuned to the intermediate frequency, the output passing through amplifier 13 to detector. 14 and thence to the amplifier 15 and speaker 16 The transistor is of a type in which the internal base resistance is large compared with the base impedance. In the equivalent diagram, Fig. 3, it is assumed that the internal emitter resistance can be neglected and the impedance is in the form of a capacitor Cb<SP>1</SP>e and the emitter resistance is rbb<SP>1</SP>. With capacitor 42 operating as a short-circuit, switch S closed, the feed-back potential E<SP>1</SP> feeds a current I<SP>1</SP> through the base circuit to generate a voltage Eble in the effective input to the transistor. This voltage produces an in-phase collector current ic and voltage Ec, a fraction of which appears across the tap on inductor 39. The variation in phase with frequency is such that when the phase of the feed-back is correct the gain of the circuit may be insufficient. By introducing a further reactance 42 the current I<SP>1</SP> is caused to lead so that the resulting feed-back voltage is more nearly in phase with the input E<SP>1</SP> and the circuit oscillates more nearly to the resonant frequency of circuit 39, 40 and the gain is maintained. Vector diagrams, Figs. 4 and 5 (not shown), illustrate the effect of employing capacitor 42.
