Title: Automatic strip-thickness adjustment appts. - ensures stabilization of thickness of rolled stock in longitudinal and transverse direction
IPC: B21B37/62
Filed: 1974-05-16
Abstract: Thickness adjustment appts. includes two closed hydraulic systems, one controlling the thrust of the work rolls, the other controlling the thrust of the back-up rolls, and providing local enhancement of roll mill stand rigidity within a force range equal to that of deviations of the roll force from the specified value. Each system includes at least on hydraulic power cylinder between the work or back-up roll supports, a second hydraulic cylinder functioning as a damper, and a controlled valve. The second hydraulic system also has a circuit for stabilizing the thrust of the work rolls in the specified range, a pressure gauge of the first hydraulic system, a setter of the rated thrust of the work rolls, an element for comparing the actual pressure with the specified value, and an actuating member. A circuit for correcting deviations of the transverse profile of the strip includes a pressure gauge of the second hydraulic system; a setter of the rated thrust of the back-up rolls; an adder connected with one input to the first system pressure gauge, a second input to the second system pressure gauge, a third input to the setter of rated thrust of work rolls and a fourth input to the setter of rated thrust of the back up rolls. The output is connected through a variable gain amplifier to the input of the comparison element and through another variable gain amplifier to the input of a controller setting the initial value of the pressure within the first hydraulic system. The device ensures stabilization of the thickness of the rolled stock both in a longitudinal and transverse direction with much higher accuracy than formerly. The device has a fast response and ensures compensation of such disturbances, as the runout of the back up rolls. The device is reliable, and is easily fitted to existing mills.
Patent FR-2270448-A1 (FR)
Title: Gas turbine combustion chamber - has spring loaded bellows controlling annular air flow control membrane
IPC: F23R3/26
Filed: 1974-05-10
Abstract: The combustion chamber has an inner cylindrical shell (8) with perforations in the cylindrical wall. Air entering the combustion chamber flows into the annulus formed between the inner and outer walls and then flows into the inner shell partly through the perforations and partly through the end inlet (19). On starting the turbine the pressure in the combustion chamber is low so that the spring (28) overcomes the internal pressure in the bellows (21) and (22) and pushes the annular membrane (20) over the inlet (19), reducing the air flow and providing a rich mixture for easier combustion. When the turbine is running normally the pressure in the combustion chamber lifts the membrane (20) to increase air flow and save fuel.

Title: Medical X-ray equipment using video storage - includes television display as well as traditional photography
IPC: H05G1/00
Filed: 1974-07-25
Abstract: A comprehensive medical X-ray equipment is described in which the entire system is controlled by a doctor from a central console. A pre-chosen dose of X-rays is applied to the patient in a sequence of bursts and the results may be recorded on cassette film, large film, video tape or directly on a television screen according to action taken at the console. The X-rays after passing through the patient are converted to a light signal which passes down a beam, of which the strength is controlled by a photomultiplier system, to both a subsidiary camera and, via an adjustable aperture, to a video receiver which in turn transmits the signal either directly to a television screen, or to a video tape unit for storage. The doctor may display the picture on this screen and simultaneously on a neighbouring screen display a previous picture from the video tape, making comparison easy. The logical operation of the system, with the various switches required, is described.

Patent FR-2366124-A1 (FR)
IPC: B31B27/00
Filed: 1976-10-01
Abstract: Envelope back manufacture for lines envelopes starts from a web whose one rim is defined by a weak line as break line (18, 19) lengthways and whose other rim has holes (16, 17) thus together forming connected front surfaces between the two rims. The larger part of each surface forms front and flap which is parted from this by a crosswise potential fold line and thus forms a transverse rim of the envelope when parted from the web. The second transverse rim is formed from the front, and the transverse rim of the flap part lies spaced from the transverse front rim of an adjoining envelope. Each flap and front is flued crossways so that the strip on the flap adjoins one transverse rim and the strip (24) on the front adjoins the other cross rim.

Title: Random access dynamic memory - has pushpull amplifier for rapid action in triggering digit line potentials and uses transistors as input resistors
IPC: G11C11/4091
Filed: 1976-12-29
Abstract: A dynamic memory system with random access uses LSI MOSFET technology with a dynamic push-pull reading amplifier. Multiple digit lines are connected to one push-pull amplifier and the speed of operation is increased by a reduction in bias period and reading time. True and complementary digit lines are connected through resistances to the inputs of an amplifier consisting of cross-coupled transistors which connect the inputs to a switching point. The input resistances preferably consist of transistors with a common gate; the digit lines are biassed to the drain supply voltage and the input transistor gates are bootstrapped to a higher voltage to transfer the different potential on the digit lines to the inout points of the reading amplifier, and the digit lines are rapidly discharged to earth.
