Title: Stabilised image night vision glasses - have Kepler lens system, light intensifier, two plane mirrors and gyroscope stabiliser
IPC: G02B27/64
Filed: 1975-08-27
Abstract: The stabilised-image night vision glasses comprise a Kepler system (1) of two convergent lenses on the same optical axis, a light intensifying disc (4) with microchannels placed in the common focal plane of the two lenses which recovers the images received between its photocell and light screen, a first plane mirror (5) integral with the rotor of a gyroscopic stabiliser (6) and a second plane mirror (7) in front of the objective lens (8) of the observation glasses. The image focus of the first convergent lens in the Kepler system coincides with the object focus of the second, the ratio between the focal distances of the two lenses being two. The first lens has a very high aperture, e.g. F/1.5 or F/1, to obtain a better efficiency of light intensification.

Title: Pre-rolling of screw rotors procedure - rolling tool has radiused tips penetrating raw material cylinder
IPC: B21H5/02
Filed: 1975-10-09
Abstract: The rotors are pre-shaped by rolling, starting from a cylinder which has approximately the same volume as the finished screw rotor. The rolling is carried out using rotating pre-rolling tools (6) which are pressed at diametrically opposite sides against the cylinder of raw material. The teeth (7) of the rolling tool have radiused tips (8) which penetrate the cylinder (9) and set it into rotation until the profile of the tips of the teeth on the rolling tools is impressed on the rotor. The screw rotor is submitted to a further pre-rolling stage which produces teeth the shape of which is such that they are suitable for further machining and which have slightly lower tooth height than is required for the finished rotor.

Title: IC engine indirect fuel injection system - injector has depression dependent piezo electric crystal oscillator
IPC: F02M63/00
Filed: 1976-06-11
Abstract: The fuel is injected into the air intake (14) by a piezo electric crystal vibrator jet (4).

Patent FR-2327459-A1 (FR)
IPC: F16J15/06
Filed: 1976-10-08
Abstract: A sealing system for a shutoff unit comprising two substantially ring-shaped sealing elements, one of which is tightly connected with the housing or with the blocking element of the shutoff unit and the other is either tightly connected with the blocking element or the housing or is formed thereat. The sealing elements are pressed against one another due to a closing movement of the blocking element for carrying out a shutoff action. The one sealing element is constructed as a thin-wall body of undulated or wave-shaped cross-section and elastically deformable under the action of the closing force, said elastically deformable thin-wall body extending over the ring width of the corresponding sealing element and in the closed position, with deformation of its wall, bearing by means of wave peaks protruding from one side of the thin-wall body against the other sealing element at least at two ring regions with line contact. The blocking element or housing which is connected with the thin-wall body possesses beneath these ring regions free deformation spaces for its wall and adjacent such spaces a respective support extending parallel to the ring region for each wave peak protruding from the other side of the thin-wall body. The marginal regions of the ring-shaped thin-wall body of undulated cross-section are prevented from moving in a manner which would increase the ring width.

Title: Tractor drawn load transporter - has forked chassis with height above ground adjustable using hydraulic cylinders acting on pivotal wheel arms
IPC: B62D53/06
Filed: 1977-03-08
Abstract: The assembly has a forked chassis (1) with wheels (2) and a towing bar (3).

Title: Screwdriver with electroplated shank - prevents hydrogen embrittlement by grinding coating off blade end
IPC: B25B15/00
Filed: 1977-05-25
Abstract: A hand tool such as a screw driver with a chrome plated shank is plated all over before the working blade is machined to a flat or cross end. The mechanically treated parts are finally burnished for anti-corrosion rust protection. This safeguards the blade against hydrogen embrittlement because the material, weakened by the galvanic treatment, is removed from the blade. The blade remains tough and can be stressed more highly.
