Filed: 1970-12-09
Abstract: 1338595 Gas turbine jet propulsion engines ADAPTRONICS Inc 9 Dec 1970 [9 Dec 1969] 58506/70 Headings F1G F1J and FIT [Also in Division G3] A system for on-line control of the thrust of a turbo-jet engine comprises first means providing a commanded thrust signal, second means responsive to on-line measured engine parameters and providing a signal of computed engine thrust, the difference between these two signals being used to control the turbine inlet area. In Fig.1, a signal F c  of commanded engine thrust is summed with a signal F NET  which indicates actual engine thrust as computed from measurements of nozzle areas and engine temperatures and pressures. The resultant error signal # is taken to a thrust controller which, subject to engine limit conditions, adds components proportional to the integral and derivative of the error Fig.2 (not shown) and controls the engine fuel flow W f . The error signal # is also used in an optimizer which controls the turbine inlet and outlet nozzle areas so as to minimize fuel flow per unit thust. In the optimizer, a predicted error signal (# P ,) Fig.3 (not shown) is passed to a performance assessment unit which also receives signals of measured engine parameters and provides an output signal (SEN V') whose sign indicates whether system performance is improving or regressing. This output is used in a correlation logic unit Fig.5 (not shown) which controls, subject to engine limits is calculated, the relevant nozzle area servo A J  of A A5 . The corelation logic unit may employ probabilistic or deterministic logic.

Abstract: 1,242,740. Squeeze-out carbon &c. papers. COLUMBIA RIBBON & CARBON MFG. CO. Inc. 30 Dec., 1968, No. 61723/68. Heading D2B. [Also in Division C3] A pressure-sensitive transfer element of the squeeze-out type is made by producing an ink layer comprising a non-transferable microporous structure of synthetic thermoplastic polymer, with exudable ink-of colouring matter and oily vehicle in its pores, applying over the ink-releasing surface of the ink layer a coating of a dilute solution of a second synthetic thermoplastic polymer or chlorinated rubber and a blowing agent in a volutile organic solvent, the second polymer being one that leaves an opaque or heterogeneous residue when the solvent is evaporated from a mixed solution of polymer and oily vehicle in a common solvent, and the blowing agent being one that decomposes at a temperature higher than that at which the solvent evaporates, and heating to evaporate the solvent and decompose the blowing agent. In the Example, a film of polyethylene terephthalate is coated with a thin layer of polyvinylidene chloride from solution in methyl ethyl ketone. This is then further coated with a composition of styrene-methyl methacrylate copolymer, mineral oil, refined rapeseed oil, sulphonated vegetable oil, blue toning paste, black toner pigment, ethyl acetate and toluol. The final coating is of polyvinyl acetate and p, p'-oxy-bis (benzenesulphonyl hydrazide) in methyl ethyl ketone. Each coating is dried before the next is applied, the last is heated to activate the blowing agent as well as to evaporate the solvent. Other polymers, solvents and blowing agents for the top coating are referred to, and this coating may also contain plasticizers, fillers or colorants. Reference is also made to inks that comprise magnetic pigments, e.g. iron oxide or colourless colour-forming reagents, and to self-supporting ink-releasing microporous layers coated as above on both surfaces.

Title: Improvements in cup separating devices
IPC: G07F13/10
Filed: 1978-10-06
Abstract: A cup separating device for a vending machine comprises a fixed body with an opening through which cups may pass. Two cup-supporting arms are pivotally mounted about vertical axes on the body and lie on opposite sides of the opening. Two pairs of cup- splitting arms are also pivoted on vertical axes above the cup supporting arms and lie on opposite sides of the opening. An actuating member is mounted on the body for sliding movement between first and second positions. It carries camming means for swinging the supporting arms and the splitting arms about their vertical pivot axes as the actuating member is moved. In the first position the cup supporting arms support the cups below the rim of the bottom cup and the cup-splitting arms are clear of the stack of cups. As the actuating member is moved towards the second position the pairs of cup-splitting arms are moved to engage below the rim of the cup next above the bottom cup and then the supporting arms are moved outwardly away from the stack of cups. Finally a projection (70) engages between the arms (10,20) of each pair of splitting arms to force them apart in the vertical direction and thus prise the lowermost cup from the stack. <IMAGE>

Title: Power assisted steering gears
IPC: B62D5/24
Filed: 1978-10-16
Abstract: A power assisted steering gear in which a piston 3 forms with its cylinder opposed chambers 4, 5. Two fluid systems are provided with respective inlets 18, 20 and with the chambers 4, 5 being located one in each fluid system. A valve 10, 15, 16 adjusted by an input component 6 when displacing the piston 3 controls fluid flow through the two fluid systems to an outlet 29. The adjustable part 10 of the valve is in the form of an axially displaceable bearing for the component 6 or a circumferentially displaceable nut through which the piston 3 is driven from the component 6 and this adjustable part is adjusted from the neutral condition of the valve so that such adjustment closes one or the other of the fluid systems to communication with the outlet 29 and provides power assistance. There is also disclosed a steering system in which fluid pressure to the inlet ports 18, 20 is derived from the outlets 31, 34 of a flow divider 32. In modifications, the steering gear can take the form of a rack-and-pinion steering gear or a cam-and-lever steering gear. <IMAGE>

Title: Control apparatus
IPC: H01S5/0687
Filed: 1978-10-17
Abstract: This invention relates to stabilising the emission intensity and wavelength of a semi-conductor laser 1. The laser driver 5 is connected in a feedback loop comprising a beam-splitter 6, a photodiode 8 and an amplifier 19, which loop controls the driver 5 to maintain the intensity of the laser emission constant. The emission is also sampled by a beam-splitter 7 and a photodiode 9, which is made frequency- dependent by a filter 10 interposed in the path of the beam. The outputs of the matched photodiodes 8 and 9 are fed via amplifiers 11 and 13 to the positive and negative inputs of a subtractor amplifier 12, the output of which is therefore dependent only upon the emission wavelength. This output is fed as negative feedback to an amplifier 15 for controlling at 14 an operating parameter (such as the temperature) of the laser 1 to maintain the wavelength constant. <IMAGE>
