Title: Process for decontamination of dairy products
IPC: C07D233/82
Filed: 1965-04-13
Abstract: A solid substantially insoluble composition, for decontaminating milk and milk products by contact therewith, comprises as an active germicidal ingredient a major proportion of N - chloro - N - bromo-dimethyl - hydantoin together with a minor proportion of a suitable non-toxic inert binder therefor.  The inert binder may be polyvinyl pyrollidone, carboxy methyl cellulose or a vegetable gum, e.g. arabic or tragacanth.  The N - chloro - N - bromo - dimethyl hydantoin may be mixed with a solution of the binder in an organic solvent (e.g. an alkanol, such as ethanol) to form a paste and the latter granulated, dried and pelletized.  Fresh milk or liquid milk products may be passed in continuous flow through germicidal tablets or pellets comprising N - chloroN - bromo - dimethyl - hydantoin enclosed in a perforated container (e.g. a funnel-like receptacle), the process being periodically interrupted to reactivate the tablets or pellets to maintain the germicidal power thereof throughout the process.  Reactivation of the tablets or pellets may be effected by washing them with water and wiping them to remove completely the fatty layer which gradually builds up upon passage of the milk &c. in contact therewith.

Patent GB-619760-A (GB)
Title: Improvements relating to panoramic radio receivers
IPC: H03J7/32
Filed: 1944-08-16
Abstract: 619,760. Panoramic receivers. FARNSWORTH TELEVISION & RADIO CORPORATION. Aug. 16, 1944, No. 15667. Convention date, Feb. 25, 1943. [Class 40 (v)] A panoramic receiver, in addition to having the usual means for visually indicating the reception of a plurality of signals, has means for converting concurrently a desired one of the said signals into sound. In the Figure, all signals lying within a predetermined frequency spectrum are picked up by the aerial circuit 10 and fed to amplifier 11 which is tunable over a selected division of, this frequency spectrum such that all signals which lie within a given band width and within the selected division are passed. The selection of the division is by a multipole wave-range switch which also controls corresponding image rejection circuits. The signals from the amplifier 11 are changed at 13 to a first intermediate frequency, which is amplified in a wide-band amplifier 15 and fed to two separate amplifiers 16, 27. The output from the amplifier 27 is fed to a narrow bandpass filter 28 which selects the signal having the mid-band frequency which is then detected at 29 for utilisation at 31. The output from amplifier 16 is fed to the oscillator-modulator 17, the oscillator portion of which is tuned by a continuously rotated condenser 18 to sweep the received frequency over the band width of the H.F. stages. The signals within the received band are thus converted successively to a time-spaced series of signals at a predetermined second I.F. selected by the narrow band-pass filter 19, and after detection at 20 are fed to the vertical deflecting plates of a cathode-ray tube 22. The horizontal sweep voltage for this tube 22 is derived from a saw-toothed generator 23, to which a positive synchronising voltage is fed from the output of modulator 17. To receive any particular station or signal, the R.F. stages are tuned until the required station is indicated at the centre of the cathode-ray tube scale. The required station will then be received at device 31. The band width swept through by the oscillator portion of the modulator 17 can be changed by switching different condensers in parallel with condenser 18. This has the effect of increasing the scale of frequencies shown on the cathode-ray tube so lending the apparatus to closer inspection of signals at the centre of the received band. The H.T. supply for the cathode-ray tube is generated by rectifying the high voltage peaks produced by the steep wave front of a sawtoothed wave in accordance with Specification 598,906, [Group XXXV].

IPC: H01J31/28
Filed: 1928-06-01
Abstract: 318,565. Pollak, J. E., (Associated Telephone & Telegraph Co.). June 1, 1928. Vacuum tubes.-In television apparatus employing cathode rays for scanning in transmitting and receiving, the end of the cathode ray tube 4, Fig. 1, at the sending station is closed by a photoelectric plate 3, Fig. 3, made of insulating material and coated on both faces with a lightsensitive material 40, 41 such as selenium or potassium hydride. Embedded in the front and back faces are grids 38, 39 respectively, which form the terminals, and extending through the plate are insulated conductors 37. The resistance of the coating on the front or image side varies with the intensity and colour of the light, and the circuit from a battery 15 is completed across the inner face by the cathode ray rendering the coating 41, at any point being scanned, conductive between the ends of the conductors 37 and the grid 39. The grid elements may be spaced apart from the faces of the insulating body of the plate, the front grid 38 however being embedded in the coating 40. The plate 3 may be made by winding insulated wire on a flat coil form, coating the whole with synthetic resin, and cutting through transversely to the wire. Or a number of thin glass strips wound with wire may alternate with plain glass strips, the whole then fused and coated with lowmelting glass, and the exposed edges of the wire ground away. The current in the circuit 15, Fig. 1, is transformed and amplified, and may be transmitted by wire or radio. The end of the receiving cathode tube 22 is a fluorescent screen or photographic plate 23. To ensure synchronization, the two frequencies applied to the electrostatic deflecting plates 11, 12 and 28, 29 are supplied from the same generators 13, 14.

Title: Improvements in motor vehicle accessory systems
Inventor: OISHEI JOHN ROFFS
IPC: B60S1/12
Filed: 1957-05-21
Abstract: 866,736. Hydraulic systems. TRICO PRODUCTS CORPORATION. May 21, 1957, No. 16126/57. Class 69 (2). [Also in Group XXIII] A windscreen wiper or other vehicle accessory is driven by an hydraulic motor supplied with liquid by a pump driven by the vehicle engine and by a wheel-driven pump, which pumps also provide the power for the gear shifting servounits of an automatic change-speed gear. As shown in Figs. 2 and 3, an automatic transmission comprises a turbo coupling or converter 15 and gear-changing mechanism having an input driven pump 16 and an output driven pump 100 which supply servo units 17. Pumps 16, 100 also supply liquid through a line 10<SP>1</SP> and a metering control 23 to an inlet line 10 of a windscreen wiper motor. Metering control 23 comprises a ball valve 26 unseated by a spring 27 acting on a pressure-responsive diaphragm 28. Excess hydraulic pressure on the diaphragm causes ball 26 to approach its seat to throttle the flow to the wiper motor. Control 23 also serves to reduce the wiper speed should the pressure in the transmission unit drop as the result of turning on the wiper. For this purpose the diaphragm is provided with a flow-restricting plate 28<SP>1</SP> having a rim 28<SP>11</SP> seating against the underface of the control body to give a restricted flow through a port 28a. Upon accelerating the engine the rim 28<SP>11</SP> is unseated to give a normal flow. The input driven pump 16 is of the sliding vanetype and its displacement is varied automatically in accordance with the pressure developed by the output driven pump 100, being reduced to zero when the output of pump 100 is sufficient to supply all needs. Pump 100 is an internal gear pump. In the modification of Fig. 6 an input driven pump 16a and an output driven pump 100a are both internal gear pumps, pump 16a supplying liquid through a valve 92a, line 116 and a check valve 103 to a line 117 leading to the gear shifting servo units and to the wiper motor. Pump 100a supplies liquid directly to the check valve 103. Pressure in line 117 is applied, through a line 118 to the underneath of valve 92a to urge the valve upwardly, upward movement of valve 92a first opening a by-pass for the output of pump 16a by opening a chamber 119 to exhaust, and then opening a chamber 120, and hence lines 118, 117, to the exhaust line to reduce the pressure in line 117. Valve 92a is spring-loaded downwardly, the spring pressure being modified by a modulator 105 responsive to the manifold vacuum. Switching on the wiper motor actuates a valve which bleeds air into the modulator, reducing the vacuum and moving the valve 92a to reduce the by-pass connections.
