Patent GB-2063023-A (GB)
Title: Code translator
IPC: H04L25/49
Filed: 1980-10-16
Abstract: When messages sent via a transmission line in a ternary line code have to be translated into a binary code, the code translator has to be able to detect code violations. The ternary coded message is made up of three-element ternary words each of which corresponds to a four-bit binary word, and four different ternary alphabets are used, choice between the alphabets to be used for each word being dependent on the need to keep disparity as low as possible. To detect code violations, the translator uses a logic circuit (LS) implemented with a PROM. This receives the ternary words from line error shift register (SR1, SR2) and a buffer memory (Z1), and supplies the binary words to an output via another buffer memory (Z2) and another shift register (SR3). The logic circuit (LS) determines, under control of the received ternary word and outputs (01-02) from the buffer memory (Z2) dependent on a previous word, the indication as to the alphabet to which the ternary word being dealt with belongs. If the received ternary word is found not to correspond to the predicted code alphabet an error indication is given. <IMAGE>

Title: Colour displays
IPC: G09F19/20
Filed: 1981-07-02
Abstract: A luminous system of chromatic dynamics is developed for producing iridescent ornamental effects and commercial effects such as for advertising billboards, providing same with iridescent effects of great impact through the application of light as the only source of colour. This system of chromatic dynamics is constituted by an optic or additive mixture of light passing through a series of optically active (birefringent) transparent media where colour results from the characteristics, thickness and molecular arrangement of the sheets used. The phase differences produced among the emergent waves depend on the difference of the indices, the thickness of the sheets and their optical properties in relation with the molecular structure in the transparent media, thereby obtaining images of brilliant colouring. The images produced on the luminous effect screen 14 may be derived from fluorescent tubes (10 or 11), overlapping diffusion discs (polariser) 9 (or 6) belt driven from one or more motors 1, a sheet 15 of clear methacrylate, a sheet 16 of frosted or flat acetate, one or more birefringent sheets 17, a scanning sheet 18 and a sheet 19 of frosted anti-reflective methacrylate. <IMAGE>

Title: Fluid injectors
IPC: F23D11/28
Filed: 1981-07-07
Abstract: A fluid injector for an oil burner for a boiler includes an injection device 2 which can be inserted into the boiler to an operating position and withdrawn from that position for inspection and servicing, and a flow control valve 3 adapted for connection to an oil fuel delivery and return circuit mounted to the boiler wall. The fluid injector also includes a fluid coupling device having male and female terminals 19 and 20, fast with the injection device 2 and the flow control valve 3, respectively, which arch disconnected as the injection device 2 is withdrawn, whilst the change-over valve remains mounted to the boiler wall and connected to the oil fuel delivery and return circuit, at which time the female terminal 20 isolates that circuit from the withdrawn injection device 2. The flow control valve 3 provides a direct flow path through itself to allow oil to circulate continuously in the oil fuel and delivery circuit. When the injection device 2 is inserted to its operating position, the male terminal 19 interconnects with the female terminal 20 to communicate the oil fuel and delivery circuit with the injection device 2 through the flow control valve 3. <IMAGE>

Title: Apparatus and Method of Controlling Temperature of a Two Evaporator Refrigeration System
IPC: F25B5/02
Filed: 1981-09-02
Abstract: In a refrigeration apparatus having a fresh food (above freezing) compartment 12 and a freezer compartment 14 with respective evaporators 18,20 connected to a common compressor 22 and condenser 16, refrigerant being fed to one evaporator or the other via a corresponding one of valves 32,34 controlled by an electronic circuit 39 which receives signals from temperature sensors 54,56 in the respective compartments, the circuit (a microprocessor) is so arranged that when both sensors demand a supply of refrigerant, priority is given to the evaporator 18 of the fresh food compartment, but only for a certain period of time. At the end of the period, even if the fresh food compartment has not achieved its set temperature, refrigerant is diverted to the evaporator of the freezer 14. The circuit control program has special features for when the apparatus is initially switched on, and provides time delays to stop ON-OFF cycling of the compressor. <IMAGE>

Filed: 1982-01-08
Abstract: The bearing sleeve 11 (111) of a reel is suspended on two bearing locations 114, 116 arranged at a predetermined distance apart, such that, as the paper strip is drawn off, one of the bearing locations 116 is relieved i.e. the bearing sleeve is lifted to a greater or lesser extent from one bearing location, whereby the restoring force holds the strip taut, whereas when the strip removal is interrupted the reel tilts back into the stable suspended position and is thereby automatically braked. The bearing locations may be provided by parallel rods spaced apart a distance preferably equal to 7/10 of the internal diameter of the sleeve 111, one rod 114 which is the constant bearing location being rotatable to reduce friction.

Patent GB-2095611-A (GB)
Title: Heating thermoplastic preforms
IPC: B29C49/64
Filed: 1982-03-30
Abstract: In a method and apparatus for radiant heating of hollow thermoplastic article preforms to the molecular orientation temperature, radiant energy is both converted to heat at the article surface and penetrates the interior of the article wall and is therein converted to heat. The principal limitation of radiant heating is the capacity of the material to conduct heat away from the surface where extreme temperatures would result in crystallisation of the material. To achieve the desired temperature uniformly throughout the article wall, brief periods of intense infra-red radiant heating are alternated with brief periods of negligible heating to take advantage of the combined effects of radiant and internal conductive heating. The article preforms (10) are rotatably supported parallel to a plane of quartz lamps (22) so that the combined patterns of radiant emission of all the lamps are distributed in contiguous segments over the preform surfaces. The articles (10) are rotated while the quartz lamps (22) are alternately energised with high and low levels of power for presettable periods. <IMAGE>

Title: Rotary coin holder mechanism
Inventor: LOUGHTON WILLIAM JOAN DENNIS
IPC: G07F15/02
Filed: 1982-06-19
Abstract: A rotary coin holder mechanism such as is used in prepayment meters is adapted for use with a new <5>1 coin. The mechanism comprises a coin pocket (15) into which extends a pivoted coin-gauging pawl (17). The pawl presents a slot to a coin entering the pocket, the dimension of the slot being such that a <5>1 coin cannot enter the slot and engages its edges, thus pushing the pawl out of the path of the coin. The coin then engages shaft (24) and urges striker (36) to engage a quantity wheel whereby the meter mechanism is driven. A coin thinner than the <5>1 coin slips into the slot in the pawl and does not move it sufficiently to lift a stop (23) out of the path of shaft (24), whereby the striker cannot engage the quantity wheel. <IMAGE>

Title: Foodstuffs for ruminant animals
Inventor: DEAVILLE SHANE PETER
IPC: A23K50/15
Filed: 1983-07-29
Abstract: A liquid feed supplement for ruminants, suitable for addition to straw or other roughage, comprises an acid solution of urea, possibly accompanied by other sources of non-protein nitrogen such as biuret and ammonium ions, sulphate ions to provide a source of sulphur and contains large, multivalent cations, such as those of magnesium or aluminium, which do not form an insoluble sulphate precipitate. The supplement can be relatively highly concentrated, containing for example between 35% and 65% urea by weight. The presence of the cations in acidic conditions has been found to prevent the crystallisation of the urea which would otherwise tend to occur on cooling. The supplement may also contain cations of trace elements such as zinc, manganese and copper. It may also contain molasses to sweeten the supplement and increase its stickiness.
