Title: Signal bandwidth reduction system - gives low redundancy and constant information flow with strongly correlated signals using sampled values
IPC: H04N19/50
Filed: 1970-09-24
Abstract: A suitable time intervals is first derived on the basis of a relevance criterium dependent on the reduction of information. A relevance signal is derived from the frequency distribution of the amplitudes of the suitable transformed source signals. The selection of relevant sampled values from the delayed and if necessary transformed source signals then controls the time intervals. Portions of the signal which may be regarded as of low importance, in particular signals which differ only slightly from previous signals, are suppressed, and the remainder of the signal can be transmission through the available channel. The system is espe. Is esp. suitable for processing television signals.
Patent DE-2058747-B2 (DE)
Title: Compact steering wheel lock - with fail-safe locking lever shortened by using intermediate pressure element
IPC: B60R25/021
Filed: 1970-11-30
Abstract: The steering wheel lock is fitted with safety interlock comprising a shaft (12) pivotted in a parallel setting to the lock cylinder and leading to a sensing surface near the key entry slot. This prevents the steering wheel locking bolt from operating until the key is fully withdrawn. In order to provide a compact sensing lever, a floating, intermediate piece is fitted between the entry slot and the lever. This results in a shorter lever and thus keeps the size of the lock housing to a minimum.

Title: Reciprocating pump control system - has bias for reverse stroke and selective bias for forward stroke and pref. uses pneumatic actuators
IPC: F04B9/137
Filed: 1972-03-24
Abstract: Two single-acting pumps can be used to deliver a uniform supply of fluid, and preferably they have pneumatic piston-type actuators. Each pump is continuously biased in the return-stroke direction, suitably by air pressure continuously applied to one side of the actuators, or by springs. When either pump is operated in the pumping direction (such as by pressure applied to the opposite side of the associated actuator) the other pump is actuated in response to the first one reaching a certain point in its pumping stroke. For this purpose pneumatic valves may serve like limit switches, each operated by one pump to control the actuator for the other, with such timing that the combined pump delivery is continuous.

Title: A communicating circuit
Inventor: O'KEEFE MICHAEL
IPC: H04Q1/30
Filed: 1995-03-24
Abstract: A communicating circuit (1) communicates a system phone (2) to a PBX (3) and comprises wires (5) and (6) for signalling between the system phone (2) and PBX (3). A transmitting circuit (10) in the system phone (2) applies a Manchester encoded digit signal on the wires (5) and (6) which is detected by a differential amplifier circuit (14) in a receiving circuit (12) in the PBX (3). On detection of a signal on the wires (5) and (6) the differential amplifier circuit (14) outputs a signal corresponding to the signal on the wires (5) and (6), which is, in turn, fed to a comparator circuit (15) where it is converted to a HCMOS logic signal suitable for feeding to a buffer of a microprocessor of the PBX. The differential amplifier circuit (14) detects a change in voltage between the wires (5) and (6) which remains constant irrespective of whether induced spurious signals appear on the wires (5) and (6).

Granted: 1998-05-06
Abstract: A 4T static RAM cell (10) comprising a flip-flop with two pull-down transistors (18, 20) and two pass-gate transistors (12, 14) is fabricated employing two separate gate oxide formations (74, 76) and associated separate polysilicon depositions (52a-b, 56). Two reduced area butting contacts (58, 60) connect to the nodes (26, 30) of the circuit (10). The reduced area butting contacts comprise vertically-disposed, doped polysilicon plugs (94), which intersect and electrically interconnect buried polysilicon layers (load poly 88, gate poly 52a) with doped silicon regions (80) in a bottom layer.   Adding the processing steps of forming separate gate oxides for the pull-down and pass-gate transistors results in a smaller cell area and reduces the requirements of the butting contacts from three to two. Further, the separate gate oxidations permit independent optimization of the pull-down and pass-gate transistors.

Abstract: PURPOSE: To obtain a robust resin sealed multichip IC package having high heat dissipation properties in which a plurality of IC chips are set in a single package. CONSTITUTION: An analog IC chip 11 and a digital IC chip 12 are bonded, on the rear surface thereof, to individual metal plates 21, 22. The metal plates 21, 22 are exposed from sealing resin 1 on the side opposite to the IC chip mounting side. When the metal plates 21, 22 are fed with power and operated, heat is dissipated from the exposed surface into the air. Since the mounting base of the analog IC chip 11, i.e., the metal plate 21, is electrically separated completely from the mounting base of the digital IC chip 12, i.e., the metal plate 22, no noise propagate on the metal plates from the digital IC chip 12 to the analog IC chip 11 to cause deterioration in the performance of the circuit during the operation.
