Title: Improved gas calorimeter
IPC: G01N31/12
Filed: 1933-03-15
Abstract: 417,856. Calorimeters. GRAY, C., 49, Grange Road, Leigh-on-Sea. March 15, 1933, No. 7797. [Class 97 (iii).] A gas calorimeter receives a constant regulated supply of gas and a proportion of air adjusted in accordance with a calibrated indicator, the calorific value being indicated by the proportion of air necessary to maintain a series of small explosions when the mixture is brought into contact with a flame. In the form shown, gas is supplied to a burner through pipe P controlled by tap Q and connected to pressure gauge R. An inverted funnel H is fixed on the burner and a calibrated disc M, threaded on the burner normally closes the base of the funnel but may be displaced axially by turning to admit varying quantities of air to the gas supply. The mixture then passes to a point adjacent a pilot flame T. The disc M is adjusted until the burner pops continually, the calorific value then being indicated by the graduation on the disc M opposite a fixed pointer D. A thermocouple connected to a recording apparatus may be placed in the flame, the disc M being set so that the burner pops at the desired calorific value. If the burner stops popping the thermocouple will register a higher calorific value and will register a lower value when the gas becomes poorer in quality. The recording apparatus may be fitted with control levers adapted to automatically control the quality of the gas.

Title: Improvements in and relating to gun mountings for aircraft and like rapidly moving platforms
IPC: F41A27/30
Filed: 1922-03-20
Abstract: 204,070. Scarff, F. W. March 20, 1922. Mountings for fuse on aircrafts.-The turning effort or resistance due to air pressure when training guns on aircraft is compensated by a device comprising one or more inclined surfaces on one part of the mounting and a displaceable spring or equivalent mechanism on another part of the mounting which is movable relatively to the first during training. The invention is shown applied to the ring type of mounting in which the gun 4 is carried in the bend of a U- shaped bracket 3 the arms of which are pivoted to a ring 2 revoluble upon a fixed circular rail 1 centred at 0. The ring carries on a bracket 6 a spring device 12 acting through bell-crank levers 10 on rollers 16 which run on an internal eccentric race 5 centred at P. The eccentric surface is so arranged that the spring resists the turning effort of the wind when the gun is being trained from front to rear, and reacts to assist the return movement. A modification is described in which the race 5 is composed of two eccentric and two concentric portions, two springs and four bell-crank levers being used in such a way that the four rollers act progressively. In a further modification, Fig. 6, the rollers run on inclined races 30 extending vertically below the rail 1.

Title: Improvements in phase modulation receivers
IPC: H03D3/00
Filed: 1943-05-21
Abstract: 564,014. Phase modulation. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. May 21, 1943, No. 8139. Convention date, May 23, 1942. [Class 40 (v)] Relates to phase-modulation receivers of the kind in which a filter is used to isolate the pure carrier from the received wave and a recombination is effected after a relative phase shift between the carrier and its side-bands ; and consists in interposing frequency-dividers in the path of the pure carrier wave and of the received wave, to enable a filter, e.g. a crystal filter, to be used which gives a phase shift greater than 90 degrees on each side of the mid-band frequency. As shown, a superheterodyne receiver S with local oscillator L feeds the phase-modulated intermediate frequency through a filter F and frequency divider D to the input of a balanced detector, energizing the diodes 5, 8 and load resistances 6, 7 in phase opposition. The-phase-modulated intermediate frequency is also fed through a similar frequency-divider D1 and a phase-adjuster P to energize the diodes 5, 8 in phase agreement. Deviation in the intermediate frequency causes an unbalance in the voltages across the load resistances 6, 7 which is applied through a smoothing circuit 11, 12 to a reactance valve R to apply a correction to the oscillator L. The demodulated signal may be taken to an audioamplifier across the resistances 6, 7 ; but, as shown, a separate balanced demodulator 17, 20 is used for the audio signal, and is fed in phase opposition at 15 from the output of the carrier filter F and in phase agreement at 16 through a phase adjuster P1 from the phase-modulated I.F. output of the receiver S. The frequencydividers may be of the multi-vibrator type, or of the kind described in Specification 556,171.

Title: Improvements in and relating to friction couplings
IPC: F16D43/18
Filed: 1946-03-15
Abstract: 609,550. Clutches. CHAPMAN, C. W. March 15, 1946, No. 8151. [Class 80 (ii)] [Also in Group XXXIV] In a centrifugally-acting clutch, brake or coupling, the friction shoes 17, Fig. 1, are pivotally attached at 20 to the outer ends of arms 15 which are resiliently pivoted to a driving boss 11 by pins 14 and rubber or other resilient bushes 13. The arms 15 are arranged to extend outwardly and forwardly in the direction of rotation so that a wedging action takes place on engagement of the shoes with the surface of the driven or fixed drum 12. Springs 21 for returning the shoes are arranged between adjacent arms 15 or between the arms or shoes and the driving boss 17, and means may be provided for varying the tension of such springs. Resilient bushes 19 for the mounting of the shoes 17 on the arms 15 may also be used. In modified arrangements the arms 15 are resiliently mounted on the driving boss by bonded rubber blocks instead of bushes and auxiliary cam means are provided for bringing the shoes into engagement with the friction surface at low speeds, as may be required, by manual operation. In the arrangement of Figs. 6 and 7, shown as a vehicle clutch, but which may also be adapted as a brake, the arms 37 are pivotally mounted through rubber bushes 38 on an engine flywheel 33 and the friction shoes 17 adapted to engage with a driven drum 12 are mounted on the arms 37 through short toggle links 42 having rubber bushes 43, 47. Each link 42 is provided with a balance weight 44 for the shoe 17, which acts to tend to straighten the toggle formed by the link 42 and its arm 37 against the frictional driving thrust. This moves an inner end 39 of the arm 37 against a spring 40 into engagement with the boss 11 and thus limits the bursting effect on the drum 12. The drum 12 is provided with a flange 50 faced with friction material and adapted to be pressed against the face of the flywheel by a pedal 51 to enable the engine to be used as a brake.

Title: Improvements in or relating to composite metal articles and methods of making the same
IPC: H01H11/04
Filed: 1945-04-04
Abstract: To avoid distortion &c. during manufacture, composite metal articles such as electric contacts, spark-gap electrodes, X-ray targets, sparking-plug electrodes, welding electrodes &c. consist of facings wholly or mainly of tungsten, brazed or welded to a backing member having similar expansion characteristics and consisting of 60 to 95 per cent. tungsten, 2.5 to 20 per cent. nickel and the remainder of copper and/or molybdenum; either of the last two ingredients being replaceable wholly or in part by gold.  Up to 1 per cent. of cobalt, manganese and iron may also be added.  In making the backing, the particles are ball milled for about 48 hours, mixed with a resin binder, screened through a 90 mesh sieve, pressed into discs large enough to allow for about 20 per cent. shrinkage, and heated to a temperature sufficient to volatilize the binder.  The discs are then pushed further into the furnace for heating to the sintering temperature of 1,000 DEG C. for about 20 minutes.  During heating the discs are placed on an alundum slab in a carbon boat with alundum sand between the discs and the slab to facilitate movement due to shrinkage during sintering.
