Title: Digital memory
Inventor: MEYERS RICHARD ING
IPC: G06F12/0897
Filed: 1983-07-27
Granted: 1988-08-25
Abstract: The memory has several storage elements sharing the same addressing and control circuit. Some (10a) of the elements have a relatively short accessing time whilst the remainder (10b) take longer to access. The address circuit (11) generates different selection signals (CAS) for the two types of element. The elements are complete memory chips with different characteristics such that they exhibit different time behaviour depending on the applied address. Disabling transistors are located in the word lines of the chips and operated by the addresses. Several accessing may be performed consecutively and overlapped.

Title: Filtering electrical signals
Inventor: CRAMPTON EDWARD CHRISTOPHER TH
IPC: H04B3/56
Filed: 1984-11-06
Granted: 1988-12-08
Abstract: A ferrite loop 21 encircles the line 11 and neutral 12, but not the earth cable 13 of a mains supply. The loop 21 also encircles a further loop 22 which comprises a capacitor 23. The further loop 22 including its capacitor 23 forms a parallel LC circuit which provides a high impedance to signals at the resonant frequency of the LC circuit in a circuit including the neutral and earth cables. The filter has substantially no effect on signals at mains frequency, since the loop 21 encircles both the line cable 11 and the neutral cable 12. There is also disclosed a filtering system comprising two such filters arranged along the arm of a T-filter system, the stem of the T comprising a series LC circuit to provide a low impedance path for signals at its resonant frequency.

Title: Active impedance transformer-assisted line feed circuit with filtering function of supervision signals
Inventor: ROSENBAUM STANLEY DANIEL
IPC: H04M19/00
Filed: 1985-05-01
Granted: 1989-11-16
Abstract: A supervision filtering function is included in a line circuit wherein tip and ring voltage amplifiers (20, 40) supply energizing current to a two wire communication line via tip and ring primary windings of a transformer and tip and ring feed resistors (at 100). The tip and ring amplifiers operate in response to a control circuit which is differentially responsive to resistively coupled voltage signals corresponding to current flows in the tip and ring feed resistors, and which is also differentially responsive to a.c. signals from a secondary winding of the transformer being coupled via a resistive capacitive network (2, 4, 6,) to an amplifier (1) in the control circuit. An output of the amplifier provides a supervisory signal. A feed switch (112, 113) is operable by a ring signal to conduct ringing currents to the communication line via the tip and ring feed resistors to the exclusion of the tip and ring primary windings. A control switch (11) is also operated at the same time by the ring signal to open circuit the secondary winding of the transformer such that the resistive capacitive network causes the amplifier to function as a low pass filter to reduce a.c. signal components in the supervisory signal.

Granted: 1990-03-15
Abstract: A fuel injection pump for internal combustion engines is proposed, in which for normal engine operation the control of the injection quantity and of the beginning and end of supply for injection is effected by means of a control slide which is axially displaceable on the pump piston and in which a radial bore (connecting conduit) controlled by the pump piston is present in the pump cylinder, with which radial bore the pump work chamber can be made to communicate with the suction chamber of the pump. The latest end of supply for the injection is determined in that after a predetermined stroke of the pump piston a relief conduit is arranged to coincide with the radial bore and thereby relieve the pump work chamber. Because the radial bore is only blocked after a pre-stroke has been executed by the pump piston the earliest supply onset also can be controlled with this bore as well.

Abstract: In the induction heating of thin (e.g. 0.5 to 3 mm diameter) steel wires (W) in continuous heating processes, relatively low field strengths of e.g. up 20,000 Am<sup>-1</sup> are employed but are chosen so as to set the relative magnetic permeability µr at 40 or more. The wire are passed through coil blocks (1), which are wound flat around a row of ceramic tubes (3) to guide and insulate the wires. The coil blocks are energized at frequencies typically up to 30 kHz. The direction of winding and/or the phase of the current is changed between adjacent coil blocks (1), or groups of blocks, to reduce voltage build-up along the wires.

Granted: 1991-06-20
Abstract: The invention provides a method and apparatus for radix- beta  non-restoring division. The division process occurs in four phases. In a first phase, the input operands are transformed to produce a divisor lying in a designated numerical range. Next, a transitional phase involves generating an initial radix- beta  quotient digit from the transformed numerator. An iterative phase of the process generates successive partial remainders according to a recursive method. From the sign and a single radix- beta  digit of each of these partial remainders, the process generates a radix- beta quotient digit. Further, a fourth phase, which may run concurrently with the transitional and iterative phases, involves accumulating succesively generated quotient digits to produce a final quotient value.

Title: Hydromechanical tool or workpiece clamping device
Inventor: BRUNNER RUDOLF
IPC: B23B31/30
Filed: 1987-02-19
Granted: 1989-10-12
Abstract: The invention relates to a hydromechanical tool or workpiece clamping apparatus comprising at least one spring clamping cylinder connected to a release conduit and adapted to be hydraulically operated against a spring force to a release position, a pump connected to said release conduit and operable for a release operation, and a discharge conduit extending from said release conduit to a fluid reservoir and including a discharge control element for discharging the pressurized fluid from said spring clamping cylinder to said reservoir after deenergization of said pump. A known clamping apparatus of this type has a solenoid poppet valve disposed in said discharge conduit and operable to close said discharge conduit for the release operation and to be actuated to a flow-through position and maintained therein for the clamping operation. The solenoid valve is expensive and requires separate control means. In contrast thereto, the invention provides the use of a discharge control element in the form of a simple bypass shutter the flow resistance of which at a constant output flow rate of the pump is greater than the pressure required for overcoming the spring force in a release operation.
