Inventor: SWIERCZ WILLIAM D
IPC: B41M5/132
Filed: 1988-08-08
Abstract: A protective overcoat is provided for a self-contained pressure-sensitive carbonless recording sheet. The sheet is initially coated with a blend of a microencapsulated color former and a color developer in a binder medium. The purpose of the overcoat is to prevent premature color formation through acci­dental rupture of the microcapsules and reaction of the color former and color developer. The overcoat comprises essentially an aqueous-based film forming material; suitable materials include: synthetic latex, polyvinylalcohol and polyvinyl alcohol-acetate copolymers, cellulose gums and ethers, acrylic resins, polyethylene oxide ethers, polyvinylpyrrolidone and copolymers of styrene, ethylene and methylvinylether with maleic anhydride.

Abstract: Glow plugs (11) in individual cylinders of the engine (10) are switched (20) in turn to a source of current (25). Temp. signals (T1-T4) derived (30) from them at other times pass to a control unit (40) which responds to additional inputs (S) by producing control signals for the injection pump (45).

IPC: A01K5/00
Filed: 1989-04-11
Abstract: The subject of the invention is an animal-feeding device (A01K 5, 39) having a closure flap. The state of the art is an "automatic feeder" having a wedge-shaped feed storage container which is open at top and bottom, tapers towards the bottom, and bears, at the front, a control slide which, together with the rear wall of a feed trough under the container, forms an adjustable gap for the passage of feed from the container into the trough. The disadvantage of this "automatic feeder" is the possibility of clogging of the gap by feed which has become damp, some of which is wasted if the gap is too wide, and the impossibility of moistening the feed by the operator, since the intentional moistening encourages clogging. The object of the invention is therefore to ensure that feed is always dispensed as required, and to make selective feed moistening possible. This object is achieved by a two-armed lever (24), one of whose arms forms a closure cap (18) on a feed dispensing aperture (14.3) of the container (16), and the other of whose arms is provided as an actuating member (22) for opening and closing the aperture (14.3). The advantage of this solution is the complete separation of the feed stock in the container from the moist/wet feed trough when the feed dispenser is closed, so that the feed stock remains dry and thus free-flowing, while the feed in the trough can be moistened or impregnated. Figure 1 is the principle illustration. <IMAGE>

Abstract: In the case where a prover A proves the validity of a pretender B to a verifier C, B receives an initial response x created by A, randomizes it with a random component and sends it as x , and randomizes an inquiry β from C with the random component and sends it as β' to A. A proves, for the received randomized inquiry β', the validity of B by a secret key s randomized with a random number r and then sends it as a proved response z to B. B removes the random component from the proved response z and sends it as A's proof to C for verification. B keeps secret the procedures for randomizing the initial response x and the inquiry , thereby maintaining secret the correlation between A - B interactions (x , β', z) and B -C interactions (x", β, z'). 
     In the case of proving the validity of a message m of a signature client B to the verifier C by attaching a signature of A to the message m, B receives an initial response x created by A and randomizes it with a random component to create a randomized response x", creates a randomized inquiry β' containing a random component by use of the randomized response x and the message m, and sends the randomized inquiry β' to A. A proves, for the randomized inquiry β', its validity by a secret key s randomized with a random number r and then sends it as a proved response z to B. B removes the random component from the proved response z ,to create a derandomized response z , which is sent to C for verification.

Abstract: A rapid acting valve (10) capable of delivering a high pressure impulse of compressible fluid has a pilot section (20), an output section (70), and in certain embodiments at least one intermediate section (50). The output section (70) and any intermediate sections are pressurized to approximately equilibrium with the inlet pressure during the load portion of the operating cycle. During the dump portion of the operating cycle, the sections of the valve cooperate to provide extremely rapid full opening of the output section (70) to release fluid under pressure from an accumulator. The valve is particularly suitable for use in combination with pneumatic impulse separation systems such as those employed for deicing aircraft surfaces. A plurality of valves may be arranged in series such that dumping of the first tier valve initiates dumping of one or more second tier valves in the series each of which in turn initiates dumping of one or more third tier valves, and so forth until all valves in the series have been actuated, each by the preceding valve to which it is operably connected by conduit means.

Abstract: The invention relates to a process for controlling the fuel supply of a gas turbine as a function of at least one turbine temperature and one shaft acceleration, in which the actual value signal of the temperature is differentiated and the gain of this signal set to act in the same direction as a function of the shaft acceleration. In the case of acceleration from idling or from the partial load range, an optimum, minimum-length and overshoot-free build-up to the full-load operating state is thereby achievable.

Abstract: Probes (18A,18B,18C) can be interchangeably mounted in the spindle (12) of a machine tool. Each probe has an optical signal transmission system, in which an optical signal from a light emitting diode (24) is transmitted to a respective receiver photodiode (26A,26B,26C). To prevent interference between the different probe signals, each light emitting diode (24) emits light of a respective different colour.

Abstract: A thermal printing system has a platen (1), a pair of pinch rollers (3,4) one end of each of which is rotably supported by each one of a pair of pinch roller levers (15,16) and is resiliently biased by a spring (17) so that each pinch roller can be brought into tight contact with aforesaid platen. An attached paper stock holding casette case (5) has a paper feed roller (6) to feed paper stock onto the platen for printing. The peripheral speed of the platen is set higher than that of the paper feed roller. The feed roller is thus utilised as a kind of brake for imparting tension to the sheet of paper being fed in order to prevent crumpling of the paper and misplacement of the printing on it.
