Patent FR-2496357-A1 (FR)
Title: Integrated dual transistor SHF amplifier - has resistive or inductive input with symmetrical FET's capacitatively cross coupled between gate and drain operated in common source mode
Inventor: DIAMAND FELIX
IPC: H03F3/16
Filed: 1980-12-15
Abstract: The high frequency amplifier (up to 10 GH3) consists of two gallium arsenide field effect transistors which are cross coupled by on chip capacitors between their gates and drains. The capacitors are produced using a chip area of similar dimensions to the transistors at these frequencies and the impedance may be set to be real or inductive at will. Inductive compensation is required for the capacitative output impedance but this is more easily provided at a power stage where dimensions are less crucial. The transistors are integrated in mirror symmetry with their sources common and gate to drain resistors are incorporated. Each drain metallisation partially covers the others gate metalisation with a spacing dielectric layer or vice versa. The amplifier is driven symmetrically with the input signal between the two gates and the output is taken between the two drains. The effect of the coupling capacitor on the output capacitance is to modify it by less than the mutual coupling capacitance. Each transistor operates in common source mode.

Title: Automatic protective shutter for banking counter - has remotely operated release mechanism and pneumatic damper controlling descent
IPC: E06B9/36
Filed: 1981-01-21
Abstract: The protective screen includes vertical blind slats which are suspended from a horizontal rail over the counter dividing staff from customers. Within a casing over the counter there is also a movable screen (1) which is normally held up away from the counter. The screen is held up by remotely controlled locking elements (2). In the event of an alarm, the movable screen may be released so that it slides down shutting off the counter. Its weight is sufficient to rotate the blind supports so that the blinds are closed. The rate at which the screen descends is controlled by pneumatic braking cylinders (6). These are adjusted to control the rate at which the air escapes from the cylinder, regulating the speed of descent.

Patent FR-2485929-A1 (FR)
Inventor: SPURRELL ROWORTH A J
IPC: A61N1/362
Filed: 1981-03-25
Abstract: There is provided an improved pacemaker for controlling tachycardia. Prior-art pacemakers of this kind generate in a short time, known as the initial delay, a stimulation after confirmation of the tachycardia. The initial delay is "scanned" from one extreme value to the next until the tachycardic state has stopped. In a few pacemakers of this kind a second stimulation is generated at a fixed point in time, which is known as the "coupled interval", after the first stimulation, the second stimulation occasionally terminating the tachycardic state even if the first stimulation has not done so. In the pacemaker according to the invention both the coupled interval and the initial delay are scanned. Furthermore, the parameters for successful termination of the tachycardic state are stored, so that on renewed occurrence of the tachycardia the previously successful time parameters are now the first ones to be tried out. The unit also permits the doctor to induce tachycardia, so that the programmable parameters can be optimally adjusted for confirmation of any tachycardia which may subsequently occur naturally.

Title: Hydraulic let-off and take=up loom motions - driven by separate hydraulic motors under individual micro-processor control
IPC: D03D49/06
Filed: 1982-01-20
Abstract: Loom has independently-controlled warp let-off and cloth take-up mechanisms comprising irreversible gear-trains driven by separate hydraulic motors. The warp-sheet tension is monitored by a mechanical sensor giving an input to a data processing unit which controls the speed of the warp let-off motor. The cloth take-up is driven by a second hydraulic motor functioning as a step motor under the control of a pulsed output from a second data processor. The data-processing units may be programmed to vary the speeds of the motors during weaving to obtain novel structures and special effects. This facilitates adjustment and control of the take-up and let-off rates, and enables novel effects to be produced. The gear trains prevent relaxation of tension during stoppages, eliminating stop bars in the fabric.

Then at least two bores (8, 9) mutually cut at an angle to the longitudinal plane (4) are drilled in the ring (1). The ring (1) is then split at the point or points (16) of its periphery so that the mutual parting surfaces (5, 6) of each point (16) lie approximately in the relevant longitudinal plane (4). Finally, a pin (7) or the like is inserted in each bore (8, 9) of the ring (1).
