Patent GB-2046563-A (GB)
Title: An arrangement for suspending spray booms on a vehicle
IPC: A01M7/00
Filed: 1979-03-12
Abstract: A spray boom having a rectangular supporting frame is suspended from a horizontal base member rigidly attached to a vehicle. Two links, which are pivoted at their lower ends to the frame and intermediate their ends to the base member, slide freely between twin cross-members, Fig 2, of the upper part of the frame, thus restraining the frame from swinging in the direction of movement of the vehicle. <IMAGE>
Patent GB-2020371-A (GB)
Title: Gas turbine combustion chamber
IPC: F23R3/12
Filed: 1979-04-30
Abstract: The chamber has primary air inlets in its peripheral wall defined by open-ended tubes (7) extending inwardly from the wall and having their outlet ends facing in an upstream direction so that each of the tubes (7) will introduce a stream of air with at least a component of motion in the upstream direction along or parallel with the longitudinal axis of the chamber, thereby to effect recirculation of fuel, air and combustion gases within the chamber. Similar air inlet tubes (8,9) may be provided for introducing secondary and tertiary air. The tubes may additionally be inclined in the circumferential direction. The chamber may be of ceramic and/or metallic material. <IMAGE>
Patent GB-2034901-A (GB)
Title: Apparatus for the spectral resolution of electromagnetic radiation
IPC: G01J3/18
Filed: 1979-07-30
Abstract: An operation at the blazing angle over an extended range of wavelengths is secured by directing an essentially parallel beam of composite input radiation onto the reflecting steps or faces 12 of an echelon grating 10 with an orientation such that the angle  alpha between the projection of the direction of the beam onto a plane normal to the longitudinal direction of the reflecting faces is essentially 90 degrees while the angle  beta  between the reflecting faces and a projection of the direction of the beam onto a plane which is normal to the reflecting faces and parallel to the length direction of said faces is variable for wavelength selection. A planar reflector 18 extending perpendicularly to the length direction of the reflecting faces may be arranged at the end of the grating toward which the radiation is reflected so that the composite input radiation beam and the wavelength-selected output beam are anti-parallel to each other. A range of wavelengths can be scanned by rotating the arrangement consisting of the grating and the planar reflector, or by providing beam entrance and exit arrangements comprising rotatably mounted mirrors in combination with fixed mirrors arranged to deliver an input beam and receive an output beam under varying angles onto and from the grating arrangement, respectively. The arrangement may be used for microwave or optical wavelengths by a suitable choice of reflectors and other components as well as the appropriate dimensions for the grating. <IMAGE>
Patent GB-2029973-A (GB)
Title: Current measurement
IPC: G01R15/18
Filed: 1979-08-03
Abstract: A direct current to be measured in a conductor 10 produces magnetisation of a core 18 which is balanced by the demagnetisation produced by a coil 16. The coil 16 is supplied with an increasing ramp current generated digitally from a clock pulse generator 24, counter 28 and D-A converter 30. The ramp is automatically terminated when a sensing coil 20 detects reversal of the magnetisation, whereupon a monostable 38 also halts a BCD counter 26 whose result is displayed 42 as a measure of the current. The starting of counter 26 is somewhat delayed by a second monostable 40 to provide an offset to compensate for the extra demagnetising current required to overcome residual magnetisation in the core 18. <IMAGE>

Patent GB-2054876-A (GB)
Title: Contact printing using copying material in web form
IPC: G03B27/04
Filed: 1980-06-26
Abstract: Where a copy of a high resolution original 63, such as a master video- disc is to be produced by contact printing, it is essential that the copying material 16 and the original 63 be brought into intimate contact. This contact can be prevented by foreign matter at the interface, by differential movements and thermal expansion during exposure, and, where a diazo copying material is used, by the gas released during the exposure. Removal of the foreign matter is assisted by operating in a vacuum, with separate supply 10, exposure 56, and take-up 100 chambers. The take- up chamber 100 is isolated from the exposure chamber 56 to reduce the loss of vacuum by a seaport 102 comprising inflatable rubber tubing (112, Figs. 5a and 5b). Cleaning is aided by a contra-moving cleaning material 31 in the supply chamber 26 and an inflatable pressure pad 59 assists contact between the original 63 and the copying material 16. Isolation from forces causing differential movement is provided by a planar isolating member (150 Fig. 11) between the pressure-pad 59 and the copying material 16, and differential thermal expansion is minimised by use of an optical filter having an appropriate pass-band to modify the light-source 90. <IMAGE>

Title: W.C. odour extractor
IPC: E03D9/052
Filed: 1981-03-06
Abstract: Offensive lavatory pan odours are extracted directly from the pan via part of the existing flush pipe, thence via an inserted Tee junction A to an electrically operated suction fan unit B, one-way valve C and silencer D and, either directly to the open air E, or to a soil vent pipe.

Patent GB-2078904-A (GB)
Title: Gearboxes
IPC: F16H57/02
Filed: 1981-06-19
Abstract: In a marine gearbox designed to suppress the transmission of gear-tooth generated vibration to the support structure, a pinion 3 is mounted in a pinion housing 1, which includes a pinion bearing 15, which in turn is resiliently mounted from a gearwheel housing 4 by springs 5. A gearwheel 2 in the housing 4 meshes the pinion 3. Inter tooth vibration is largely absorbed by the pinion structure rather than transmitted through the relatively massive gearwheel 2 and gearwheel housing 4 to the support structure. The resilient mounting has such stiffness that the characteristic natural frequency of the pinion assembly, in respect of tooth generated vibration, lies between one third and one half of the lowest tooth contact passing frequency. <IMAGE>

Patent GB-2081055-A (GB)
Title: Time Division Switching System
IPC: H04M3/56
Filed: 1981-07-23
Abstract: A multimodule time division switching system is disclosed in which intermodule calls are served by transmitting call information words over a bus system (114) interconnecting all modules (105). Each transmitted word contains information specifying the receiving module identification number, the time slot in which the call is to be served in the receiving module, as well as the message or intelligence representing the subject matter of the call. A FIFO memory (204) in each module (105) is used as an input buffer to temporarily store each received word and thereby reduce the need for short term time slot synchronization between modules. Each word received by a module is temporarily registered and such a registered word is only moved into the buffer when that word pertains to an intermodule call presently being served by the module. The buffers are repetitively scanned to read out any call information stored therein which information is applied to the appropriate part of the respective module. <IMAGE>
