Filed: 1923-08-22
Abstract: 202,994. Piccard, A. Aug. 22, 1922, [Convention date]. Void [Published under Sect. 91 of the Act]. Gas analysis.-In apparatus for continuously indicating the proportion of one or more gases in a gaseous mixture, the mixture is passed through a chamber in which the gas in question is absorbed and the consequent reduction in pressure indicated. In determining the proportion of carbon dioxide in flue gases, gas is continuously drawn by means of a suction device g through the tube b, filter c, tube d, absorption vessel e, and tube f. A gauge m indicates the varying pressure in the absorption vessel. In a mcdification, shown in Fig. 2, two parallel circuits are provided, only one of the absorption vessels e, o being active. The gauge m connects the vessels e, o as shown. The tubes d, f, n, p are preferably of capillary bore, and their action may be accelerated by an additional tube q. The gases may be dried before treatment. The absorption vessel e, which in the form shown contains pumice-stone impregnated with caustic-alkali solution, may alternatively comprise a diffusion appliance or means for liquefying one or more constituents of the mixture.

Title: Process for the manufacture of therapeutically valuable gold compounds
IPC: A61K38/01
Filed: 1936-08-01
Abstract: Gold keratinates are prepared by treating degradation products of keratins, obtained by acid hydrolysis unaccompanied by reduction, with gold compounds.  The liquid product of acid hydrolysis is neutralized and then directly treated with the gold compound.  In a modification, the hydrolysis of the keratins is not carried out to complete solution by means of the acid but is completed by a treatment with proteolytic enzymes.  The products, which possess enhanced therapeutic activity, are preferably isolated by conversion into their water-soluble alkali metal salts, followed by precipitation with an organic solvent. According to the example, hair, wool or horn is heated on the water bath with dilute hydrochloric acid until dissolved, neutralized with concentrated ammonia and treated with auric chloride solution until the precipitate formed no longer passes into solution; after neutralization with caustic soda, the solution is poured into alcohol when the gold keratinate which contains 6 per cent of gold separates out.  The samples furnished under Sect. 2 (5) comprise gold keratinates prepared by (1) hydrolyzing wool with dilute hydrochloric acid, neutralizing with ammonia, slowly adding a solution of HAuCl4 with stirring, dissolving the precipitated gold keratinate in caustic soda and pouring into alcohol; (2) heating hair with dilute hydrochloric acid and after neutralizing the liquid product with ammonia, gradually stirring in a solution of HAuCl4 which has been neutralized with caustic soda, and pouring into alcohol, whereby a product is obtained containing 33 per cent of gold.  The Specification as open to inspection under Sect. 91 also refers to feathers, claws and nails as keratinous starting materials, and to auric oxide and aurous iodide as suitable gold compounds.  As proteolytic enzymes, pepsin, papaine and cathepsin are mentioned, as well as pancreas extracts and trypsin-kinase.  It also describes the use of sulphuric, phosphoric and hydrofluoric acids for the hydrolysis, also of organic acids such as formic and glacial acetic acids and glacial acetic acid containing hydrogen halide, and of acid chlorides such as thionyl chloride.  It further states that the hydrolysis may be effected at room temperature with gaseous hydrogen chloride in the presence of moisture and that the speed of hydrolysis with hydrochloric acid is influenced by the presence of small quantities of water.  This subject-matter does not appear in the Specification as accepted.

Title: Manufacturing porous bodies of resin-bonded fibrous material
IPC: D04H5/04
Filed: 1971-04-19
Abstract: 1348896 Moulding resin bonded fibrous materials A FRANCESCHINA and R BARTULI 19 April 1971 [10 Feb 1970] 21421/71 Heading B5A In a process for the production of porous, resin bonded, fibrous articles, crimped fibres 1 are pulled, by means 12, through a guide 2 and into a vat 7 of a thermosetting resin 8 of the type which is adapted to be subjected to two polymerization stages-an intermediate stage in which it becomes hard and insoluble but capable of melting, when subjected to further heating, to give a final polymerization stage in which it is infusible-the soaked bundle 3 of fibres is passed through rollers 9, 6 to remove excess resin, through a drying and pre-heating chamber 10, and into a draw member 11, where the bundle is stretched, shaped and heated to a temperature at which the intermediate polymerization state is achieved; the shaped rod 103 so produced is pulled through the belts 112, 212 of the means 12 to a cutting device 13, the cut lengths 203 are then heated in a mould (14, Figs. 2-5, not shown) to the final polymerization stage. The final heating, which melts the intermediate polymer, allows the stretched fibres to relax and assume, at least partially, their original crimped configuration. In relaxing, the fibres expand to some extent and create a porous structure. The resins used may be phenolic, or an amino resin. Alternatively, using a modified apparatus a thermoplastic resin may be employed. The fibres can be natural, synthetic, or a mixture of both.

Title: Laser communication system
IPC: H01S3/13
Filed: 1966-05-16
Abstract: 1,136,635. Lasers. HUGHES AIRCRAFT CO. 16 May, 1966 [16 Aug., 1965], No. 21551/66. Heading H1C. [Also in Division G1] In a laser communication system receiver in which the information carrying beam is heterodyned with a laser local oscillator beam the frequency of the laser local oscillator is adjusted to compensate for doppler shift on the information carrying beam. In a space communication system, the beam from a fixed frequency f 0  laser 98, Fig. 4, on a spacecraft 90 is modulated by information from a source 93 and beamed to a ground station 100 where it is mixed with the beam from a tunable laser 108. The output of mixer 102 should be at a frequency f if , but is modified by the doppler shift f d . Feedback is provided from the I.F. stage of the receiver to keep the frequency of laser 108 equal to f o +f d + if f so that the output of mixer 102 is truly f if . Laser 108 simultaneously produces a beam 105 of frequency f o -f d -f if  which is used to transmit information to the spacecraft where it arrives doppler shifted to f o -f if  ready for mixing with the beam from laser 98. Laser frequency control system.-The tunable laser comprises a tube 42, Fig. 2, containing ionized gas surrounded by a coil 60. Coil 60 is energized by signal from the I.F. stage indicating deviation from the desired f if  and varies the amount of Zeeman splitting to compensate. The output beam 65, the components of which are circularly polarized in opposite directions is converted to orthogonally plane polarized beams by a quarter-wave plate and split by a Wollaston prism. Part of the beam applied to the mixer is selected by a mirror 82 and applied to a circuit 52 which maximizes the amplitude of the oscillation by energizing a piezo-electric transducer 50 carrying one of the mirrors 48 which defines the resonant cavity of the laser. In a modification, Fig. 5 (not shown), in which the resonant cavity has different apparent length for the components f o +f d +f ij  and f o -f d -f if , mirror 48 is fixed and a beam polarizing and splitting assembly similar to 70 is provided at the other end of the tube 42. The beams produced are directed on to mirrors (146), (147) on opposite sides of a piezo-electric transducer energizable to increase one path and decrease the other path simultaneously.

Title: A rotatably mounted fluid operated linear actuating device
IPC: B23B31/175
Filed: 1966-05-16
Abstract: 1,127,584. Chucks. ERICKSON TOOL CO. 16 May, 1966 [14 March, 1966], No. 21572/66. Heading B3B. In a rotatably mounted fluid operated linear actuating device which may be used to hold a chuck in any selected position despite a loss of fluid actuating pressure, a check valve arrangement is provided which traps fluid in a motor cylinder tending to move the motor piston in one direction so long as there is little or no fluid tending to move the piston in the opposite direction and which allows the trapped fluid to escape when the fluid pressure tending to move the piston in the opposite direction is high. The piston rod 9 of the device is shown connected to the jaws 10 of a chuck 11 of known type for actuation of the jaws 10 into and out of work-gripping position on axial movement of the piston rod 9 in opposite directions. The spindle S which supports the chuck body 12 is attached to the fluid housing 2 of the motor cylinder by a coupling 24 and is driven by a machine tool (not shown). A rotary coupling 28 is mounted on the housing 2, the coupling having ports 28, 29 through which air or other fluid is selectively admitted under pressure to the cylinder 7 to move the piston 8 in opposite directions with the housing 2 and spindle S rotating. One way check valve assemblies 45, 46 are concentrically located respectively in recesses 36, 42 in the housing part 5 and piston rod 8, each check valve consisting of a sleeve 47 having a seat 48 therein and the poppet valve 49 which is yieldably held in engagement with the seat 48 by a spring 50 permitting flow of fluid under pressure from the associated ports 29, 30 into the respective ends of the fluid cylinder 7. A plunger 52 is provided in each check valve assembly, the plunger having a greater effective area than the poppet valve and an extension 53 projecting towards the poppet valve to cause the same to open the associated poppet valve for exhaust of fluid. To move the chuck into workpiece gripping position air or other fluid under pressure is admitted to the rod end of the cylinder through the port 30 and check valve 46 to move the piston 8 to jaw-closing position. At the same time the high pressure produced in the rod end of the cylinder acts on the plunger 50 and check valve assembly via passage 37 and branch passage 55 to open its associated poppet valve 49 for allowing the escape of fluid from the head end of the cylinder 7 through the check valve assembly 45, passage 35 and port 29. Fluid entering the rod end of the cylinder 7 cannot escape through the check valve assembly 46 until high fluid pressure is admitted to the head end of the cylinder 7 to cause the plunger 52 of the check valve assembly 46 to move to a position unseating the associated poppet valve 49. Release of the trapped air is effected by supplying fluid under pressure through the port 29 to the head end of the cylinder 7 via the passage 35, recess 36 and check valve assembly 45.

Title: Improvements in or relating to the tuning of radio receiving apparatus
IPC: H03J7/16
Filed: 1934-07-26
Abstract: 443,363. Wireless receiving-apparatus. COLE, Ltd., E. K., Priory Crescent, Southendon-Sea, and BRADFIELD, G., 161, Hainault Avenue, Westcliff-on-Sea. July 26, 1934, No. 21823. [Class 40 (v)] The change in the mean value of a direct current caused by the tuning of a wireless receiver controls a device which tends to maintain the change until the receiver is in tune with the signal from the carrier of which the direct current is derived. The Figure shows a diode load resistance 1 the changes in current in which are applied to a valve V which controls the magnet 10 of a brake on the tuning mechanism. When the receiver is within, say, 5 kc /s of tune and switch 14 is closed the discharge of condenser 21 places sufficient bias on the valve V to operate the magnet 10 and release the brake. The coil 12 is pivoted in a magnetic field, but being short circuited is turned by a control spring to vary the tuning. This produces variation of the current in resistance 1 to maintain the movement till the receiver is in tune, when the current is constant and the brake is applied. When switch 14 is opened, charging of condenser 21 causes release of the brake, while the coil 12 returns to its normal position in the magnetic field. The control current may also govern a switch to operate a lamp indicator to show that a signal is being received. The invention is preferably applied to a superheterodyne receiver of the type using a high intermediate frequency and a fixed filter for the signal frequency circuits so that tuning is effected solely by the oscillator condenser. Specification 441,691 is referred to.
