Title: Improvements relating to fuel injection systems in internal combustion engines
IPC: F02M49/02
Filed: 1950-01-11
Abstract: 704,234. Fuel-injection pumps. DOXFORD & SONS, Ltd., W., PURDIE, W. H., and JACKSON, P. Dec. 28, 1950 [Jan. 11, 1950], No. 773/50. Class 102 (1). [Also in Group XXVII] In a fuel-injection pump, the piston a, is actuated by a piston b subjected to the pressure in the engine cylinder and the delivering passage e is controlled by the delivery valve f, which is maintained closed against the fuel pressure by a spring h acting through lever j and rod k. The valve f is relieved of pressure of the spring h, to permit it to open, by moving the lever j by rod w actuated by an engine driven cam 1. The time of the injection may be varied by moving the rod w relatively to the cam by the shaft x. The cam 1 may have ahead and astern portions s, t and shaft x can be used for reversing. The spring h may be replaced by means applying hydraulic loading which is relieved by means operated by the cam. Alternatively the valve f may be opened directly by the cam against the spring or hydraulic pressure. The quantity of fuel delivered is controlled by a by-pass valve d actuated by a lever d<SP>2</SP> connected to the piston b, the point of closing being determined by a cam d' that may be actuated by the same control as shaft x. The lever j may operate the air-starting valve (see Group XXVII), Specification 704,233 is referred to.

Title: Improvements in and relating to radio-gramophone apparatus
IPC: H04B1/20
Filed: 1933-01-09
Abstract: 393,888. Wireless receiving - apparatus. SEIBT AKT.-GES., DR., G., 29, Kolonnenstrasse, Sch÷ne berg, Berlin. Jan. 9, 1933, No. 775. Convention date, Jan. 7, 1932. [Class 40 (v).] A radio set in which volume is controlled by varying the grid bias of a variable-mu valve is converted into a gramophone or low-frequency amplifier employing the same volume control by switching the pick-up &c. into the grid circuit of the valve, which, when receiving radio signals, may operate at high or low frequency. As shown, the first high-frequency valve 1 of a radio circuit takes its grid bias from a slider 8 on a resistance 7. When the switch 9 is operated it connects a pick-up Gr in place of the radio input circuit. Other switches 10, 11, 12 are operated simultaneously with the switch 9, 10 connecting the plate of the valve 1 to the input of the final amplifier 5, 11 adjusting the screen-grid voltage of the valve 1, and 12 opening the cathode connection of the detector 4. If a variable-mu valve is employed between the detector 4 and output valve 5 the pick-up may be switched into its grid circuit, in which case a variable grid-biasing resistance such as 7, 8 serves for volume control for either radio reception or gramophone reproduction.

Title: Improvements in or relating to control circuits for cathode ray tubes
Inventor: URRY DENIS EDWARD
IPC: H04N5/257
Filed: 1956-01-11
Abstract: 825,052. Automatic control systems for cathode-ray tubes. RANK CINTEL Ltd. Jan. 11, 1957 [Jan. 11, 1956], No. 989/56. Class 38 (4). [Also in Group XL (c)] The brightness of a spot scanning the screen of cathode-ray tube 1 is maintained substantially constant except during the blanked flyback periods by the use of a photo-multiplier 4 receiving light from the screen and delivering a signal to the grid of cathode-follower 11, the output from which is amplified by triode 17 D.C. coupled to cathode-follower 21, and applied to the cathode of the tube. Positive pulses are applied to terminal 27 during fly-back periods to raise the common cathode of triodes 26 and 17 sufficiently to cut off valve 17 and hence interrupt the feed-back circuit and cut off the beam current of tube 1. In order to prevent an insensitive area of the screen, which causes a large positive excursion at the grid of valve 11, producing excessive beam current in tube 1, a diode 13 limits this excursion to a value set by potentiometer 16. Specification 505,197 is referred to.

Title: Inference processing system
Inventor: ONO KENJI
IPC: G06F9/44
Filed: 1989-01-06
Abstract: PURPOSE:To efficiently execute a production rule by giving an orientation from the general situation of an inference processing, and also, to avoid waste of an inference by eliminating the redundancy of the rule, and to execute the inference processing at a high speed by providing a strongly connected component decomposition part, etc. CONSTITUTION:A strongly connected component decomposition part 14 derives a production rule for satisfying a transition condition between all states that can be taken by each variable treated in the production rule stored in a rule storage part 13, as a digraph matrix. Moreover, by bringing the digraph matrix to strongly connected component decomposition, a production rule for satisfying a variable condition of each strongly connected component and a transition condition between each strongly connected component is derived as metaknowledge. Subsequently, an inference part 16 executes an orientation from the generation situation of an inference, based on the metaknowledge, extracts the production rule stored in the storage part 13 and executes efficiently an inference processing. Also, a rule registration deciding part 12 decides whether the strongly connected component is varied or not by adding the rule at the time of registering the rule to the storage part 13, and in the case when it is not varied, the registration is suspended, therefore, the inference processing is executed at a high speed.

IPC: H03K5/00
Filed: 1979-01-06
Abstract: PURPOSE:To compress a pulse change rate by converting the result, which is obtained by counting input pulses by an up/down counter, to feedback pulses consisting of a pulse train. CONSTITUTION:Pulse signals 1a become output pulse signals 3a through up/down counter 2 and converter circuit 3 and are fed back to down count entrance D. Output pulse signals 3a are repeat of pulse signals 1a, and the number of pulses of signals 3a is set to be equal to the number of pulses of signals 1a. Consequently, pulse signals 1a and output pulse signals 3a have paring correspondence relations in time T1 where pulse signals 1a have a normal-state repeat frequency. Meanwhile, output pulse signals 3a have a repeat frequency changed gradually at the beginning of times T2 and T3 where pulse signals 1a have a transition-state repeat frequency. As a result, the pulse change rate is compressed.
