Title: Decomposition of hydrazine
Inventor: FORTE MARK ROBERT
IPC: C01B3/04
Filed: 1964-09-18
Abstract: In a process for the decomposition of hydrazine at about 2500 DEG  C. the product gases are passed through a perforated structure of composed of an alloy consisting essentially of 60-85% nickel, 0.25% iron and 11-22% chromium, thereby instantly decomposing the ammonia to hydrogen and nitrogen and so maintaining the temperature of the reaction chamber at about 1800 DEG  F. The catalyst resists, nitriding disintegration and erosion and has a useful life of 50 hours.  The structure may consist of screens, say 25, of 2 inches diameter of wires of 0.023 inch diameter and openings of 0.078 inch.

Title: Improvements in or relating to amplitude modulators
Inventor: HARDING RICHARD MORRIS
IPC: H03C1/36
Filed: 1968-08-09
Abstract: 1277199 Amplitude modulation EMI Ltd 6 Aug 1969 [9 Aug 1968] 38154/68 Headings H3R and H4F An amplitude modulator comprises a network of non-linear impedances D4, D5, D6 having an unmodulated carrier applied to D4, a modulated carrier extracted from D5 and the modulation signal applied to vary the slope conductance of impedance D6 oppositely to that of impedances D4, D5. The impedances D4, D5 may be constituted by a symmetrical transistor. As shown, modulating pulses are applied at B and are fed via resistors R7, R10 to diodes D4, D5. Alternatively the modulation may be applied between the anode of D6 and the line 0. The carrier signal, which may be a colour sub-carrier, is applied at B and the carrier signal path including input and output series resonant circuits C2, C3, L1 and C4, C5, L2. As described, the invention is applied to the production of colour burst signals, but can also be used to produce subcarrier signals representative of different colours by varying the phase of the subcarrier and suitably controlling the amplitude of the modulating pulses. This latter application can be used to vary the colour of caption displays by producing signals corresponding in time to black and white caption signal and using them to modulate the subcarrier amplitude. The D.C. level of the resultant signal can subsequently be varied to vary the luminance.

An ionisation manometer is connected to an evacuated system by a ground joint 11 and comprises a circular screen electrode 32 outside and concentric with a circular wire cathode 31, a cylindrical grid 23-30 and a straight wire collector electrode 21. The grid comprises a plurality of coiled wires 25-30 extending between two rings 23, 24 connected to, and supported by leads 15, 16. The cathode is heated by a voltage source 40 and the grid is maintained at a positive potential by voltage source 41 so that some electrons are accelerated into the space between the grid and collector and produce positive ions which drift towards the collector which is maintained at a negative potential by voltage source 42. This ion current is measured by a meter 43 and indicates the gas pressure. The screen, grid and collector may be freed of occluded gas by heating them by means of transformers 34, 35, 33. The coiled wire 25-30 may be replaced by straight wires, and the screen electrode may comprise two circular wires on opposite sides of and equidistant to the cathode wire. All the electrodes are preferably made of heat resistant material such as tungsten, molybdenum or tantalum.

As shown, the igniter is incorporated in a pocket gas lighter and the actuator 5 comprises a slidable knob. In the inoperative position shown, the legs of a U-shaped spring 7 carried by the knob engage a pin 9 on the hammer so that when the knob is slid in the direction D the hammer and striker spring assembly is carried with it until the legs engage wedge-shaped surfaces 10 which splay them apart and release the hammer. In the return direction of the knob the legs ride over the pin 9 as the hammer is re-set. Movement of the knob in the direction D also opens a flame aperture and operates the gas valve of the lighter and at the end of the first stage of the resetting action, the valve and flame opening are held open so that ignition of the lighter can be maintained as long as desired without holding the knob.
