Patent FR-2452808-A1 (FR)
Title: Engine inductive ignition circuit - uses numeric circuits, load and RPM sensors, to control coil current duration
Inventor: MENARD CHRISTIAN
IPC: F02P3/045
Filed: 1979-03-30
Abstract: The ignition circuit is for IC engines. The circuit is inductive and uses numeric techniques to control the duration of the magnetising current in the ignition coil primary winding. The numeric circuits (4) are controlled by a clock source, can be retarded and generate a square wave output which can have a fixed duration or have a duration which is a function of engine RPM. The advance and retard control circuit (3) is fed by an RPM transducer (1) associated with the flywheel and referenced to the cylinders dead points and a load transducer (3) in the inlet manifold. The clock source provides a signal (EN) whose frequency is a function of RPM, the numeric circuit output supplying a high voltage spark source (5) and a distributor.

Title: Tubular fabric-knitted on two-needle-bed Raschel warp knitting machine - forming two fabrics joined by binder yarn
IPC: D04B25/14
Filed: 1979-03-27
Abstract: A warp-knitted fabric having tubular sections is formed on a Raschel machine with two needle beds and at least three guide bars, where a fabric is knitted on each needle bed. The two fabrics are connected to each other by binder yarns which are fed by a single guide bar between the two guide bars knitting the fabrics for the tubular assembly. The tubular fabric may exhibit loops or pile on one side, and is highly elastic. It may be used for bags, tights and tubular surgical dressings.

Title: Travelling scissors for cutting-across packaging film - for cutting film being carried on a conveyor
IPC: B26D1/04
Filed: 1979-04-05
Abstract: A device for cutting continuous film transversely to produce a series of individually wrapped packages comprises a pair of scissors-type blades mounted on a carriage which can (a) be raised to allow a pack to pass beneath the carriage, and (b) can follow longitudinal motion of the film while the carriage moves to perform a transverse cut. Used for wrapping and sealing packages between two layers of film which are simultaneously cut and welded. This requires less frequent sharpening than a beam knife pressing against a supporting pad, and more suitable for cutting film riding a moving conveyor, without damaging the conveyor.

Title: Control system for IC engine fuel-air mixt. - has regulator controlling air such that fuel-air mixt. remains constant during change from slow to normal speed
IPC: F02M3/09
Filed: 1979-05-14
Abstract: A first hole (24) connects a channel (20) associated with the engine slow speed to the carburation chamber (10) above the butterfly flap (14), that leads to the inlet tube (16) of the engine. A semi-parallel circuit (34-44) admits air or another gas that passes into the slow-speed channel (20) downstream of a calibrator (21) and the nozzle (22) upstream of the first hole. The circuit consists of a regulator (40) whose cross-section is determined by at least one engine parameter, in order to modulate the relative pressure prevailing in the slow-speed channel such that the flow of air through the calibrator and thus the fuel injected by the nozzle (22) is adjusted to make the fuel/air mixt. constant during the transition from slow to normal speed.

Title: Control of access to semiconductor memories - uses access controller requiring validating inputs before opening and gate linking address bus and address decoder circuits
Inventor: BASSET JEAN-CLAUDE
IPC: G06F12/14
Filed: 1979-11-30
Abstract: Unauthorised access to electronic memories containing confidential information is prevented by placing an access control circuit between the address bus and the address decoder circuits. The access control circuit (19) requires validating input signals (28,29) before it will supply a signal (17) to one input (16) of an AND gate (15) whose other input (14) is from the address bus (11). Thus, the required address will only be passed to the address decoder (26) when the AND gate (15) has signals from both the address bus and the access controller. This prevents access to the memory for either reading or writing. The required access code may be extracted by the controller from the memory in a preliminary cycle. The access controller program is stored in fusible link semiconductor read only memory (ROM).

Title: Negative dobby-shedding mechanism - has horizontal jack levers with cable connections to operating levers beneath heald shafts
Inventor: PALAU JOSEPH
IPC: D03C1/14
Filed: 1980-08-06
Abstract: A dobby shedding mechanism for a high-speed loom is mounted alongside the heald shafts, and at the same height. The jack levers are attached to heald-operating levers beneath the heald frames by cables, such that a vertical lifting movement of the jacks produces a downward force on the operating levers, to move the healds from the top to the bottom shed position. Springs attached to the other ends of the operating levers return the healds to the top shed position when the jack levers are lowered. This construction eliminates the superstructure above the healds, facilitating servicing of the loom. It also considerably reduces vibration when the loom is operating at high speed.
