Patent FR-2291420-A1 (FR)
Title: Reversing vehicle transmission system - has belt rollers with gears moved to gether and apart by lever
Inventor: COUTORIER GERARDO LEVET
IPC: F16H9/04
Filed: 1975-11-12
Abstract: The system is for tractors, industrial machines etc, having a belt running over driving and driven drums, whose distance apart is variable. The driven drum (2) transmits the drive to wheels or crawler tracks via a chain etc. and its spindle is mounted in two bell-crank levers (4), pivoted by a selector lever (10) acting on a bar (6) joining them together. This alters the distance between driving (1) and driven (2) drums, each of which has a gearwheel fixed to and rotating with it. Thus the gearwheels are brought into engagement with each other the belt being simultaneously rendered ineffective, reversing the drive.

Title: Holder for needle and thread, esp. a suture - protects needle point, holds thread securely, convenient in use
IPC: A61B17/06
Filed: 1975-11-14
Abstract: A holder for a needle of thread, esp. a surgical thread, consists of a kind of envelope with a flap. It is formed by thin parallel plates attached in part along their edges by side walls having an outwardly facing concave section for winding on the thread. A narrow slit is provided in one plate for the point of the needle and there are open grooves for trapping the ends of the thread. A flap covers the needle. The needle point is fully protected and cannot damage the outer strip-off cover in which the needle and suture can be gas sterilised. The coils are large enough to prevent any creasing of the suture, the threads are held very securely by the pressure of the outer wrapper, and the needle and thread are quickly made available for use.
Patent FR-2338219-A1 (FR)
Title: Overhead cableway with tensioner - uses light counterweight prevented by locking device from rising above initially set position
IPC: B66C21/00
Filed: 1976-01-16
Abstract: The overhead cableway has a system for producing the initial tension in the driving rope, a driving pulley and return pulleys, a crab and a counterweight. To cause the driving pulley (3) to engage with the rope only a single relatively light counterweight (1) is provided placed initially in a position to suit the most favourable position of the crab (4) for the driving rope (7). A locking device (8) prevents the weight rising when the crab position is less favourable for the rope. The maximum travel distance for the crab, between two end positions, is initially determined, and over this distance the weight stays in the locked position, only sinking automatically into a lower one if the rope stretches, to maintain the minimum initial tension.

Title: Screwed coupling for flexible pressure hose - has external sleeve compressing hose into grooves in internal sleeve
IPC: F16L33/22
Filed: 1976-02-20
Abstract: The screwed coupling (1) connects the flexible hose (7) to the screwed fitting (2). A sleeve (8) with a flange to suit the nut (3) is fitted over the flexible hose (7). A second sleeve (11) with a flange (19) and circumferential grooves (18) is fitted in the bore of the flexible hose (7). The conical end of the sleeve (11) is fitted into the conical inlet (4) of the fitting (2) with the threat (10) of the nut (3) engaging the thread (9). As the nut (3) is tightened the material of the bore of the flexible hose (7) is forced into the grooves (18) to make a pressure tight joint. The joint is simple and reliable and can be easily dismantled when required without needing special tools.

Title: Determining optimum conditions for solvent adhesives - for bonding aluminium foil to glass sheet
IPC: G01N19/04
Filed: 1976-02-24
Abstract: Determination of optimum conditions for using solvent adhesives is effected by experimentally measuring evaporation time of a solvent quantity corresponding to optimum bonding capacity, by coating >=1 of the two air-tight elements to be bonded with the adhesive. The whole adhesive-coated surface of one of the elements is progressively covered with the other element within a given time. After a period of standing, the two elements are progressively separated over their whole length while plotting the force applied as a function of the duration of this operation. Used partic. to bond an al foil to a sheet of glass, using a roller to unroll the foil onto the glass.

Title: Navigation training unit using light spot projector - has light source, projection screen and adjustable opening controlled by independent driving elements
IPC: G03B21/00
Filed: 1976-04-02
Abstract: The screen projection is of a movable light spot for training equipment in navigation, and uses a unit, with adjustable opening and a light source which illuminates this opening. The unit contains two movable elements. Each element has a transparent slot (19, 20) for the light from the light source. The two slots (19, 20) intersect in a point (18) which represents the opening. Driving elements (25) move the two elements independent of each other and thus displace the opening. Each of the two elements contains a plate which up to a thin, straight transparent line does not transmit light. The line forms the slot. The plates are adjacent to each other.

Title: Secateurs with jaws sprung apart - have adjustable stop limiting extent jaws open with notch-locked lug on pivotable arm catching shoulder
IPC: B26B13/16
Filed: 1976-04-30
Abstract: The tool is of the secateur or scissors type, has recoil springing (7) which automatically opens the jaws (4) after a cut, and includes an adjustable stop (8, 9, 10) which controls the extent the jaws (4) can open. The extent that the jaws open may, thus, be set to suit the user. The stop may comprise a pivotable arm (8) with a projecting lug (9) which engages alternative notch holes (10) in the major surface of one of the lever arms (1). One of the notch positions may correspond with jaw (4) closure, and once engaged in a particular notch the lug (9) engages a shoulder (11) on the counter arm (2) to limit relative arm (4, 5) articulation. The arm (8) pivots about an extension of the arm fulcrum (3) and may be mounted on a cone spring. The cone spring enables the arm (8) to be rocked see-saw fashion to disengage notch (10) and prior to pivoting towards an alternative notch.

Patent FR-2367319-A1 (FR)
Title: Circuit integrating signals over long period - resets integrator and increments counter at specified threshold to overcome amplifier drift
IPC: G06G7/186
Filed: 1977-10-07
Abstract: An analogue and digital circuit network for time integrating input signals over a long period overcomes the problem of amplifier drift by resetting the integrator and incrementing a counter when the integrator output attains a specified threshold level. The circuit performs the same task electronically as certain mechanical graph plotters, planimeters and the like. An amplifier input stage drives the integrator stage using a feedback capacitance. The signal from this, representing a short term time integral of the input signal is fed to a comparator stage which fires a pulse generator when a specified threshold is exceeded. This increments an output digital counter with display and also discharges the integrator with a FET.
