Title: Improvements relating to telephonic appliances
IPC: H04R25/00
Filed: 1931-08-19
Abstract: 376,986. Sets for deaf persons. BALBI, C. M. R., 4, Iddersleigh House, Caxton Street, London. Aug. 19, 1931, No. 23335. [Class 40 (iv.)] Hearing aids for deaf persons are constructed to have frequency characteristics determined by a prescription for each individual obtained by taking the " threshold of audibility " curve for the person and comparing it with the standard audition area of the normal ear. The hearing aid is given the desired characteristic by the use of electrical or mechanical wave filters or by suitable construction of the microphone or receiver. As shown, the area contained between the upper and lower curves in the normal audition area, the ordinates representing sound intensity. The lower line of the cross-hatched area represents the threshold of audibility of a bassdeaf person. A curve is drawn through the centre points of the verticals through the crosshatched area, and the hearing aid is constructed to give this characteristic, the amplification being nil in the region of 8000 cycles since the person concerned has normal hearing in this region.

Abstract: 730,264. Metal vapour lamps. BRITISH THOMSON-HOUSTON CO., Ltd. Aug. 27, 1953 [Aug. 29, 1952], No. 23713/53. Class39 (1). A high-pressure mercury vapour lamp comprises an elongated tubular envelope having a length at least 15 times its diameter, a pair of electrodes sealed into opposite ends of the envelope, a starting gas of xenon or krypton whose partial pressure at the operating temperature is a substantial proportion of the total pressure and which produces a radiant output uniform along its length irrespective of small variations in the envelope diameter. The envelope 1 may be of quartz with diameter variations up to 20 per cent, having a length of 125 cms. and internal diameter of 1 cm. The electrodes may consist of tungsten rod 4 overwound at one end with a tungsten spiral 5 containing a sliver of thorium, the other end of 4 being welded to a tungsten foil 6 which is sealed through the envelope. The preferred pressure of xenon is 25 mm. which rises to 250 mm. at an operating temperature of 2700‹ C., the total operating pressure lying between and 3 atmospheres. Curves are given which show that when argon is used as the starting gas the light output at 3650 Š is non- uniform along the tube, being less at points of minimum diameter, but that when xenon is used the light output is substantially constant. This effect is attributed to variations of the partial pressure of the starting gas along the tube, the effect decreasing in the order neon, argon, krypton, xenon. The use of xenon also increases the light output. Specifications 645,122, 660,258 and 663,878 are referred to.

Title: Improved process for the manufacture of artificial sponges and similar spongeous artificial products
IPC: C08J9/00
Filed: 1935-08-24
Abstract: Porous artificial sponges and similar spongeous artificial products are produced by moulding or shaping a mixture of 20 grams of hemp, 400 grams of viscose containing 10 per cent of cellulose, and 1200 grams of crystalline decahydrated sodium sulphate.ALSO:Porous artificial sponges and similar spongeous artificial products are produced by moulding or shaping a mixture of cellulose solution, fibre, and crystalline substances, inserting the plastic mass entirely or partly into a bed of polyhedric bodies or bodies having curved surfaces, incrusting the bodies into the surface of the mass by pressure, coagulating the mass, and subsequently eliminating the incrusted bodies.  The incrusted bodies may be substances which are soluble in the usual treatment or finishing baths or in other baths of an appropriate solvent, e.g. carbonates which may be removed by treatment with an acid, or may be insoluble substances such as gravel, ground quartz, or metal bodies, which may be removed by hand or mechanically by impact.  In an example, 20 grams of hemp are mixed with 400 grams of viscose containing 10 per cent of cellulose and 1200 grams of crystalline decahydrated sodium sulphate; a quantity of the mixture is roughly moulded, inserted in a bed of gravel of an average diameter of 6 mm. and pressure is applied to incrust the gravel in the surface; the viscose in the mass is coagulated and fixed in the usual manner, and the incrusted gravel then dislodged.

Title: Improvements in or relating to combustion products power plants

Filed: 1936-09-02
Abstract: 484,196. Combustion - product power plant. MAINA, J. Sept. 2, 1936, No. 24024. [Class 7 (i)] [Also in Groups XII and XXVIII] A charge of air after being compressed to a high degree in a, compressor a is transferred to a generator of combustion products under pressure by positively actuated means comprising two opposed pistons c, d, the charge being delivered into the space between the pistons and rapidly expelled from the space through a port h leading to the generator. As shown, the pistons move in a cylinder b at right-angles to the cylinder a. A communicating port e between the cylinders is utilized for the inlet of air to the cylinder a through an inlet port g and an annular recess f around the piston d, and for the transfer of compressed air from the cylinder d to the space between the pistons c, d. The cranks from which the pistons c, d are driven are so arranged relatively to each other that those pistons control the inlet and outlet ports g, e, h at suitable times, and the pistons gradually approach each other during the final stage of delivery through the port h to the generator, in order to compress the charge further and to expel it completely. The transfer of combustion products from the generator through a passage h<1> to a power cylinder B is effected by opposed pistons c<1>, d<1> similar to the pistons c, d but without a recess such as f in the piston d<1>. The generator may be of the form described in Specification 447,266.

Title: Improvements in ordnance and machine guns
IPC: F41A1/04
Filed: 1935-08-28
Abstract: 578,726. Ordnance; machine guns. SALMON, P. Aug. 28, 1935, No. 24026. [Class 92 (ii)] Relates to ordnance and machine guns operating by the internal combustion of hydro-carbon fuel on the principle of the two-stroke Diesel engine cycle; the energy of explosion in a chamber sealed by the projectile being utilised to propel the projectile. According to the invention, compressed air from a reservoir 13, is introduced into. a working chamber 2 sealed by the projectile 4 and is compressed to the temperature of ignition by one or more rams 1, hydrocarbon fuel being injected into the compressed air to burn the fuel and produce gas pressure to expel the projectile and recock the rams. In the form shown, the action is started by operating a screw valve 19 to admit air from reservoir 13 through a valve 16 and passage 17 to the chamber 2. The valve 16 is opened by pressure on a piston 20 and the air pressure on the outer face of a piston 6 effects through the ram 1 the compression stroke in the chamber 2. Fuel is injected by a valve 21 of the kind described in Specification 278,423, [Class 7 (iii)]. On the inward stroke of the piston 6, air in space 9 previously admitted through valve 12 is forced through a non-return valve into the reservoir and through a pipe 26 is led to auxiliary piston devices 25, 32 for feeding projectiles to the firing point. The explosion expels the projectile and returns plunger 1 to permit supply to chamber 2 of compressed air through passage 17 for scavenging and recharging. The projectiles 4 are threaded between strands of wire forming a flexible belt and pass between recesses in wheels 27 being rammed by the piston device 25 into pockets 23 in a chamber 22 rotated by a ratchet-rod 33 on the piston device 32. The projectiles are thus brought in turn to the firing position in line with the barrel 5. Twin rams 1 moving in opposite directions are preferably employed as shown and in a modification (not shown) these are kept in phase by hydraulic pistons fixed to the outer ends of the rams and moving in cylinders which are interconnected and which may trap liquid to arrest the rams.
