Abstract: 594,077. Electrostatic instruments and circuits therefor. RADIO CORPORATION OF AMERICA. July 7, 1944, No. 13051. Convention date, June 12, 1943. [Class 40 (iv)] [Also in Group XL] A frequency-modulated transducer device such as a gramophone pick-up or a microphone consists of a variable differential condenser, one half of which varies the frequency of an oscillator and the other half of which varies the frequency of a discriminator circuit in the opposite direction so increasing the effective response. Differential inductive means may alternatively be used. In Fig. 5a, movement of the stylus causes variation of the capacities 14<1>, 15<1> and 15<1>, 16<1> in opposite directions. Capacity 14<1>, 15<1> tunes coil 11<1> to form with the first two grids of valve 10<1> an oscillating circuit electron-coupled to the discriminating circuit comprising inductance 23<1> tuned by the capacity 15<1>, 16<1>, its resonant frequency being such that the oscillator frequency corresponds to a straight slope on its response curve. The resulting amplitude modulated signal is rectified by the diode portion of valve 10<1> to produce audio-frequencies via the R.F. choke L. In a modification, Fig. 5 (not shown), a pentode is used for the oscillator-discriminator and a diodetriode for subsequent rectification and amplification. Figs. 6 and 7 show a pick-up which comprises a sapphire point 60 mounted on a stylus wire 61 of rectangular cross-section fixed to the brass block 62 which is screwed to the block 63. Condenser plates 65, 66 (66 removed in Fig. 6) are mounted on the block 63 parallel to the stylus wire 61. Damping member 67 suppresses torsional resonance of the wire. Block 63 is secured to the tone arm 70 by shock absorbing flexible plates 80, 90. The transmission lines 92, 93 from the condenser plates run in separate channels in the tone arm in which they are supported centrally on plastic blocks to minimize their capacity and increase shielding. The stylus wire is connected to the main body of the tone arm which is earthed. A push-pull form of condenser microphone for use with the above circuit has a diaphragm consisting of the centre plate of a differential condenser, a fixed back plate, and a fixed front plate perforated with conical holes to permit the passage of sound to the diaphragm.

Patent GB-135479-A (GB)
IPC: F01K1/08
Abstract: 135,479. Aktiebolaget Vaporackumulator. Nov. 16, 1918, [Convention date]. Steam regenerative accumulators.-Relates to a steam plant provided with a steam accumulator serving to receive the surplus steam from and to maintain the pressure in the various steam supplies of the system. A valve Oi between two low-pressure pipe lines L3, L4, to which the accumulator A is connected, is so controlled by the pressure in the high-pressure or boiler pipe line L, that, when the pressure in the pipe line L1 rises, the valve is opened and the surplus steam passes into the accumulator, the valve being again closed when the pressure falls to the normal. The pipe line L1 is in communication with the lower pressure lines through reduction valves R12, R13, R14. If the steam consumption from, say, the line L2 decreases, the pressure in the line rises, thus closing the valve R12 and consequently causing an increase of pressure on the high-pressure line. This increased pressure opens the valve Oi, which then allows more steam to pass through the valve R13 into the accumulator. The reduction valves Ra4 and R13 co-act in the manner described in Specification 129,272. The high-pressure steam may operate a three-stage turbine, the high and intermediate stages of which exhaust respectively into the pipe lines L2, L3.
Patent GB-135594-A (GB)
IPC: D06F71/06
Abstract: 135,594. Goold, L. W., (American Laundry Machinery Co.). Nov. 27, 1918. Ironing-machines with pressing action only.-Comprises a construction of small press for pressing clothing and laundered articles, of the type in which relatively - movable pressing members are ' closed by lever mechanism prior to fluid-pressure being applied to effect a final heavy pressure on the articles. Particular features in the present construction comprise the arranging of the pistonof the fluid-pressure cylinder in line with, and connected directly to, the shaft carrying the movable pressing member, and the special operating means whereby both the closing movement of the press and the power pressure are effected by one movement of a single treadle. The initial movement of the main operating-treadle 10 closes the press members through lever linkages and at the same time compresses springs so that the valves of the fluid-pressure apparatus are operated during the latter part of its movement. When the treadle 10 is depressed against the resistance of the spring 11, the toggle 20, 21 is straightened to raise the sleeve 24 fixed on the rod 5. This movement raises the movable pressing head 4 into contact with the fixed head 3. The treadle is also connected to a rod 60 which carries a sleeve 59 acted on by opposed springs. The sleeve 59 is connected to the valve rods 54, 55. The valve rod 54 operates a valve which controls the passage between the pressure main and the cylinder 6, while the valve rod 55 operates the valve 53 controlling the passage between the cylinder and the exhaust pipe. Prior to the depression of the treadle the valve rod 54 is held down by the pressure fluid in the main, while the valve 53 is open to exhaust. Depression of the treadle therefore first rocks the lever 57 about the rod 54 until the valve 53 closes, and then compresses the lower spring 63 until the pressure is sufficient to raise the valve rod 54 by rooking the lever about the valve rod 55. Pressure fluid then enters the cylinder and raises the piston and the rod 5. The slot 22 in the toggle permits the rod to rise without disturbing the treadle mechanism. When released, the treadle is restored by the spring 11 and first closes the valve on the rod 54 and then opens the exhaust valve 53. The weight of the movable pressing head then restores the parts to their normal positions. The main treadle 10 is locked in the depressed position by a projection 26 engaging under an inclined lug 27 on a release treadle 28.

Title: Detergent compositions
IPC: C11D1/74
Filed: 1946-05-06
Abstract: Detergent compositions comprise a b -monohydroxyethylamide of a fatty acid of from 8 to 20 carbon atoms and at least 10 per cent by weight of an ethylene oxide condensation product of a fatty alcohol or a fatty acid of the formula RX(CH2CH2O)nY, wherein R is an aliphatic radical of from 8 to 22 carbon atoms, X is -COO- or -O-, Y is hydrogen or an alkyl radical of not more than 5 carbon atoms and n is a whole number greater than 3.  The fatty alcohols and fatty acids which may be used include cetyl alcohol, sperm oil alcohol, dodecyl alcohol or mixtures of such alcohols as are obtained for example by reduction of natural oils and fats, stearic acid, oleic acid, lauric acid and natural mixtures of such acids, for example, coconut oil acids.  The components of the detergent are mechanically mixed together, preferably with heating, to a temperature which may or may not be sufficient to melt any ingredients solid at ordinary temperatures.  The known detergent properties of ethylene oxide condensation products of the type used in these compositions are said to be improved by admixture of the b -monohydroxyethylamides with these products.  Other components commonly added to detergent compositions such as alkali phosphates, silicates and borates may be added.  In an example, 13.6 parts of a condensation product of cetyl alcohol with 17 molecular proportions of ethylene oxide and 6.4 parts of the b -monohydroxyethylamide of coconut oil fatty acids are melted and stirred together until a homogeneous mixture is obtained.

Title: Improved process and apparatus for treating exhaust gases from internal combustion engines
IPC: F01N13/02
Filed: 1932-05-12
Abstract: <PICT:0405976/III/1> Exhaust gases from internal-combustion engines are treated for the removal of carbon monoxide by passing them through a chamber containing granular activated aluminous catalysts such as bauxite, materials rich in aluminium hydrate and certain aluminates.  Air may be mixed with the gases before they pass over the catalysts.  The Figure shows a purifier for application to a motor car, the exhaust gases passing from the engine exhaust pipe 1 through a Venturi 2 where they are mixed with air and then entering the purifier by way of a perforated tube 9 of refractory material or metal or gauze coated with aluminium.  The gases pass through the catalyst 12 of activated aluminous material, through gauze 6 around a baffle 5 and into a chamber containing copper oxide 13 from which they pass through a perforated outlet pipe 10.  A reserve supply of the catalyst is contained in a hopper 14 provided with a spring cap 15.  The iron or steel fittings inside the purifier are coated with aluminium.  The reaction in the purifier may be initiated by highly reactive catalysts such as platinised asbestos, by the introduction of catalytic dust into the mixture of gases and air before it enters the purifier or by a small electric heater.  A mixture of granular catalysts may be used which become fritted when strongly heated to form a highly porous mass.  For activating the aluminous material, compounds of copper, iron, manganese, magnesium or titanium, may be used or chromic acid; chromic oxide; bichromate of aluminium, iron or copper; potassium permanganate alone or with copper salts or with copper and manganese salt; copper sulphate alone or mixed with one-fifth the quantity of manganese sulphate; ferrous sulphate; copper chloride, copper and titanium chloride, copper sulphate and one-fifth the quantity of manganese chloride; copper acetate solution followed by potassium permanganate; copper lactate followed by potassium permanganate, copper sulphate, manganese chloride, sugar or other suitable organic compound, potassium permanganate and finally ignited and washed; manganese nitrate, chromic acid and copper bichromate mixed with a trace of silver bichromate; potassium permanganate followed by copper chloride, manganese chloride and copper nitrate.
