Patent FR-2497907-A1 (FR)
Title: Annular dynamic composite seal - has inner seal material surrounded and protected by outer resilient material
Inventor: DECHAVANNE JACQUES
IPC: F16J15/32
Filed: 1981-01-14
Abstract: The seal ensures dynamic sealing between a piston and a cylinder or a guide and a piston shaft separating two enclosures in which there are different pressures. An annular element (1) comes into contact with the fluid and with the rigid surfaces, completely encloses an insert (2) and is made of plastics having good resistance to friction, extrusion and chemical attack. The seal insert material (2) is chosen for its residual elasticity and may be circular, elliptical or trapezoidal in section.

Title: Elastic pads and bandages for covering open wounds - involving open and closed cell materials to just contain and prevent the outflow
Inventor: PICOLET JEAN-PIERRE
IPC: A61F13/15
Filed: 1981-02-06
Abstract: A bandage for a bleeding wound comprises a pad of absorbant flexible foam covered on the non-contact face with an impermeable layer of closed cell foam. Allows the wound to discharge some fluid before establishing a back pressure to staunch the flow and thus assist clotting. The impermeable skin prevents the superficial appearance of loss of blood from a covered wound which might otherwise distress the applicant or the victim. Pref. the pad is of polyurethane foam with an impermeable cover on one face of closed cell polyethylene foam which has been irradiation cured. Designed to ensure sufficient pad contact pressure without risk of strangling the blood supply to the affected limb unnecessarily.

Title: Lateral location slide-guide on table - uses aligned holes to locate pin with radially flanged end and normal threaded hole for clamping bolt
Inventor: SACHOT MICHEL
IPC: F16C29/08
Filed: 1981-04-03
Abstract: The system fixes a slide-guide (1) on a support (2), using a pin (3) which either passes through or houses in the guide.

Pins may be sited at intervals along the length of the guide in conjunction with ordinary holding down studs (13), and may have two crowns (4,5) which straddle the interface.
Patent FR-2483641-A1 (FR)
Inventor: KLINGENFELD DIETMAR
IPC: G03F9/00
Filed: 1981-05-11
Abstract: Optical arrangement for projection lithographic devices having only one light source, a selecting optical element, a condenser, a mask and optical beam splitters in the vicinity of the mask. The optical arrangement is used in the production of semiconductor components for the purpose of transferring mask structures onto substrates. It is intended to contribute to raising the degree of automation, the precision and the productivity of projection lithographic devices. The object of the invention is to configure the optical arrangement in such a way that it permits a large quantity of light to be transmitted at the adjusting and exposing wavelength and simultaneously allows the adjustment and exposure of one chip or a chip group. For this purpose, the selecting optical element is constructed as a movable reflector having at least two different regions. The beam splitters are assigned selecting optical means which permanently cut out the actinic light.

Title: Amino:benzoic acid prodn. from nitrotoluene - by oxidn. to nitrobenzoic acid and electrochemical redn. to amino:benzoic acid with simultaneous regeneration of oxidising agent
Inventor: CHAUSSARD JACQUES
IPC: C25B3/25
Filed: 1981-09-14
Abstract: Process for the preparation of aminobenzoic acids comprises a first stage in which nitro toluenes are oxidised to nitrobenzoic acids, followed by a second stage in which the nitrobenzoic acids are electrochemically reduced is characterised in that the oxidising agent used in the first stage is regenerated at the anode of the electrolyser in the second stage, simultaneously with the electrochemical reduction. The preferred oxidising agent is a sulphochromic solution, esp. an aqueous solution of 3-20 wt.% of chromic oxide and 10-95 wt.% of sulphuric acid, which optionally contains chromium sulphate and other additives. Preparation of amino-benzoic acid, esp. para-amino-benzoic acid, which are useful in the pharmaceutical and dyestuff industry. The present invention simultaneous reduction of the nitrobenzoic acids and regeneration of the oxidising agent gives excellent yields of pure product and avoids the cost and toxicity problems in recycling the chromium salts, in addition to needed only one electrolyser reducing electric energy requirements.
