Title: Improvements relating to radiation detectors
Inventor: ALLENDEN DENNIS
IPC: G01T1/178
Filed: 1961-09-18
Abstract: 969,862. Measuring radiation. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Sept. 4, 1962 [Sept. 18, 1961], No. 33369/61. Heading G1A. In an apparatus for detecting radio-active material in gases, more particularly Pu-239, U-235 and U-238 in the atmosphere, a strip of material, e.g. paper coated with an adhesive, is exposed to the gas in region A for a predetermined period and is then moved to region B where it is exposed to an alpha particle detector in the form of a back-biased barrier layer or PN junction semi-conductor device, the resulting electrical pulse output from the detector being passed to an analyser comprising a plurality of channels each arranged to respond to pulses of a different amplitude characteristic of one of the radio-active materials it is desired to detect. A switch S1 permits the output from any channel to be applied to a scaler, the switch being ganged to a further switch S2 through which a clock delivers timing pulses to a timer which operates the control mechanism for a motor which moves the strip. The motor, when started, rotates a fixed amount and then stops (or runs very slowly) automatically, the intervals between movements being determined by the setting of switch S2 depending on the type of radiation it is desired to investigate. The natural air activity can be selected by channel 1 the output of which is recorded by an electro-mechanical register with print wheels giving a printed tape output. A detailed circuit for a pulse amplitude selection channel is given. Specification 969,861 is referred to.

Title: Process for the preparation of oxidation products of ethylene polymers
IPC: C08F8/06
Filed: 1971-07-16
Abstract: 1339360 Oxidizing ethylene polymers FARBWERKE HOECHST AG 16 July 1971 [18 July 1970] 33485/71 Heading C3P Polymers of ethylene, optionally with one or more C 3-8  α-olefins or cycloolefins, are oxidized by a process which comprises dispersing the polymer in a molten state in water, in the presence of a gas containing oxygen while intimately mixing the components. The medium may contain wetting agents, e.g. ethoxylated alcohols and phenols, and oxidation may be effected with air or ozone or in the presence of an oxygen transferrer that acts catalytically, e.g. nitrogen oxides. Catalysts, e.g. peroxide, heavy metal compounds and alkali and alkaline earth metal compounds, may also be present. The reaction may be accelerated by the presence of oxidized polyolefin and/or previously used reaction medium. The products may be used in moulding, coating, polishes, cosmetics and as substitutes for industrial fatty acids, and may be hardened with metal hydroxides, further oxidized, esterified or saponified. Many examples are given in which polyethylene, and ethylene/ propylene and ethylene/butene copolymers are oxidized in water in the presence of t. butyl hydroperoxide, di-t-butyl peroxide, benzoyl peroxide, cobalt stearate and/or sodium stearate, potassium permanganate or benzoyl peroxide and sodium stearate, with air, ozonized air or oxygen.

Abstract: 1,108,073. Cooling fluid-operated brakes. CATERPILLAR TRACTOR CO. 5 Aug., 1965 [18 Aug., 1964], No. 33514/65. Headings F2E and F2F. [Also in Divisions F1 and F4] In a brake cooling system for vehicles a brake control valve 30 when actuated by a brake pedal (not shown) establishes communication between a source of pressure fluid such as an accumulator 18 and the brake cylinders 142 of a brake 26 to cause actuation of the brake, a control valve mechanism 20 being operative in response to the brake control valve 30 and adapted to supply cooling fluid to the brakes. Two engine driven hydraulic pumps 10 and 12 are provided which respectively supply fluid under pressure to the accumulator 18 for actuation of the brakes when the brake control valve 30 is actuated, and a valve 22 which is selectively operable to actuate a jack mechanism 23 for raising and lowering a vehicle dump body. The pump 12 also supplies cooling fluid to the brakes via valve 22, conduit 98, filter 100 and conduits 60, 62. The pumps 10, 12 also supply cooling fluid to the brakes when no braking effort is required. Whenever the brakes are applied the output of the pump 10 is in communication with a conduit 46 and an hydraulic motor 28 is operated to drive an intermittently operable fluid pump 14 which supplies additional cooling fluid via conduits 60, 62 to the brakes 24, 26 and via conduits 154, 156 back to a reservoir 16 after being cooled by a heat exchanger 158 and passing through a strainer 160.

Abstract: 1,141,546. Photo-cell-controlled monogrammic sign. FAIR-PLAY MFG. CO. 27 July, 1966, No. 33777/66. Heading G5C. [Also in Division H4] In a system for displaying pictorial images and/or messages on banks of lamps, a first circuit connected to all lamps controls the illumination of lamps for the display of messages and a second circuit connected to a portion only of the lamps and comprising a photo-cell array controls the illumination of lamps in this portion for the display of pictorial images. In the embodiment described the display area is divided into two sections. Coded " message " signals derived from a typewriter or from a punched card or tape memory installation actuate solid state switches controlling the energization of lamps in either or both of these sections as required. Pictorial images are generated in one section only by projecting a still or cine film image on to a bank of photo-cells whose outputs actuate Schmitt trigger circuits controlling solid state switches of lamps in that section.

The system may be a process control system operating in a hazardous atmosphere encountered in the production of chemicals or refining of petrol. A central station of the system communicates with remote stations via a coaxial cable 3 connected to transceivers at the stations. Each transceiver includes a pulse transmitter 23, energized from the A.C. source via a rectifier 31, and a pulse receiver 24. Digital pulse signals to be transmitted are coupled to the bases of transistors 27, 28 which supply voltage pulses to the winding 22 via a capacitor 36. The pulses transmitted or received over the cable 3 are at a high frequency so that the impedance of the winding 22 is high and efficient transmission of the pulses occurs. However, the low frequency supply voltage is applied to the winding 22, the impedance of the winding is low and the high current causes saturation of the transformer to limit the transfer of energy to the secondary winding. Metal film resistors 25, 26 disconnect the winding 22 without melting, causing a flame or excessive heat if the supply voltage is applied to the winding. Fuses 60 become open circuit if an abnormal voltage is applied to the winding but is insufficient to cause the resistors 25, 26 to interrupt the circuit.
