Title: Spark timing control circuit for controlling the timing of spark ignition of an internal combustion engine
IPC: F02P5/15
Filed: 1979-10-26
Abstract: A spark timing control circuit for an internal combustion engine, includes a speed band selector circuit which responds to an electrical signal indicative of engine speed and provides an output signal indicative of which of a plurality of speed bands is occupied by the engine speed. Spark timing information for each speed band is stored in a memory as a first word in units of angular rotation of the engine for the heaviest engine operating load, and a second and third words indicative of the slope of straight line approximations to the curve of engine load plotted against advance in said angle units. A build up circuit responds to an electrical signal indicative of the engine operating load and computes from the second and third words a build up word which is added to the first word in an accumulator so as to derive an accumulated word in said angle units indicative of the desired spark timing. A residue angle counter, clocked by angle clock pulses from a clock converts the accumulated word into a corresponding time delay which is used to control the timing of the occurrence of spark ignition.

Title: A DC/AC converter
IPC: H02M7/538
Filed: 1980-03-21
Abstract: The converter includes a transformer (T) whose primary winding is fed by a battery via two power transistors (Q1, Q2) controlled alternately by means of an oscillator circuit A.

Title: Pressure die casting
IPC: B29C45/77
Filed: 1980-06-16
Abstract: In a pressure die casting machine the high pressure forces for the afterpressure phase are produced by means of a pressure multiplier (5, 6). The working pressure provided in chamber (4) by the multiplier piston (6) is controlled by the pressure in the annular counter pressure chamber (8) of the multiplier cylinder (5). The pressure in the counter pressure chamber (8) is adjusted by a pressure limiting valve (17) whose response threshold is determined by a control pressure storage device (26). In order to ensure a rapid build-up of afterpressure without overshoot or over-control at least the control pressure storage device (26) in the circuit arrangement (17, 19, 21, 25, 26, 33) precontrolling the pressure limiting valve (17) is constructed to be elastically deformable so that the circuit arrangement reacts to pressure fluctuations on attainment of the response threshold by the pressure in the counterpressure chamber (8) with an elastic closing force whose characteristic as a function of the valve travel is non- linear.

Title: Stretch-blow moulding a two layer article
IPC: B32B27/36
Filed: 1980-08-30
Abstract: A method for producing a hollow product, such as a bottle 4, by injection stretching and blow moulding involves injection moulding a two-layer parison 3 with a closed bottom, one layer 1 consisting of a readily stretchable, blow mouldable resin (e.g. polypropylene) and the other layer 2 consisting of a resin which is hard to stretch and blow mould (e.g. acrylic resin). The parison is adjusted to an appropriate temperature before stretching the two layers of the parison and at the same time blowing air into the parison, while the latter is mounted in a blow mould, to form the article by blow moulding. The method avoids the difficulty of rupture, and undue thickness variation in the layer of resin which is hard to stretch and blow mould.

Title: Method and arrangement for signaling the transmission mode of a communication system.
IPC: H04Q11/04
Filed: 1982-09-23
Abstract: A communication system signaling method and arrangement utilizing direct current signaling over the line loop connecting a line terminal to a central office. The direct current provides concurrent active/inactive line terminal condition signaling and analog/digital information transmission mode signaling between the terminal and central office. A current flow in a first direction over the line loop signals the analog mode, while a current flow in the opposite direction signals the digital mode. A change in the operating mode is signalled by blocking current flow at the line terminal. The resulting interruption of current flow is detected at the central office which responds by reversing the direction of current flow over the line loop. Current flow in the line loop indicates the active (off-hook) condition of the line terminal, while the absence of current flow for a predetermined interval indicates the inactive (on-hook) condition.
