Title: Electric cable gland for machine tool terminal boxes - uses two-part screw-assembly gland with sealing ring and deformable region bent onto cable sheath during tightening
Inventor: DAUBOIN GILBERT
IPC: H02G15/013
Filed: 1981-11-24
Abstract: The electric device is used to seal round and clamp the electric cable and is formed of two pieces which are assembled together to receive the cable. A toroidal ring sealing joint is forced against an internal truncated conic surface in one of the two parts. An internal cable locking ring having a deformable part is acted on by the truncated conic surface. The gland is constituted externally of two mating threaded sleeves, one female, the other male, both parts having hexagonal surfaces to allow gripping with spanners. After the cable has been passed through, the gland can be assembled and tightened to compress the seals and bend the deformable region onto the cable sheath.

Title: Method of preparing natural beverages having a low alcohol content,beverages and various products prepared by applying that method
Inventor: BONNEAU MARC
IPC: C12G3/08
Filed: 1982-01-13
Abstract: The method consists in subjecting a natural alcoholic liquid to three successive steps of non denaturating physical fractionation; the first step is a molecular ultrafiltration under low pressure through a semi-permeable ultra-filter the splitting threshold of which is between 30,000 and 1000 and preferably around 10,000; the second step is a reverse osmosis step applied to the ultra-filtrate resulting from the preceding operation through semi-permeable membranes the splitting threshold of which is between 500 and 100 and preferably around 250; the third step consists in evaporating and distillating under vacuum, at low temperature, the ultra-filtrate resulting from the second step. Natural beverages having a low alcohol content thus obtained. Products obtained from the filtrates or retention products of the various steps of the method.

Title: Video disc player head - detects video data and reference signals recorded as variations in geometrical configuration on the surface of a disc
Inventor: TAKAHASHI NOBUAKI
IPC: G11B21/02
Filed: 1982-02-25
Abstract: The video disc played by this machine has four rasters of pulse-code-modulated video information on each rotation of a spiral track of depressions. Each track, which is 1.5 micron wide, is bounded by two reference signal tracks which are used by the play-back machine to keep the pick-up centred on the track, thus relieving the need for pick-up guide tracks. A third reference signal is used by the play-back machine to discriminate between data and reference signals. The detected signal is amplified, and fed in modulated form to standard video processing equipment. It is also demodulated, filtered and fed to discriminators which measure the levels of the reference signals and feed back a servo signal to a motor control circuit which keeps the pcik-up on the track.

Patent FR-2509985-A1 (FR)
Inventor: EIBOFNER EUGEN
IPC: A61C1/14
Filed: 1982-07-23
Abstract: In a dental handpiece (1) with a drive shaft (4) located in its interior, the tool (11) with its shaft (10) can be connected so as to be fixed against rotation with a tensioning element (7) of the drive shaft kept in the tensioning position by a restoring spring (12), it being possible to bring the tensioning element into the release position counter to the force of the restoring spring by means of a pressure member (14) actuable by a handle (13). In order to avoid unintentional actuation of the handle, especially as regards assumption of the release position, and in order to set the spring force of the restoring spring so as to be comparatively high, the pressure member can be actuated by the handle via a force transmission unit (15) which exerts, to a certain extent, a self-locking effect.

Abstract: A process for the preparation of delta-ketocarboxylic acid esters by addition reaction of a ketone and of an acrylic acid ester in the presence of a catalyst is described, which catalyst is formed by a mixture of a primary amine component and a catalytic material component which is accelerated by water. The catalytic material component which is accelerated by water, which is essentially or completely insoluble in the reaction medium, is selected from a group of materials which consists of an alkali half-salt of phthalic acid, an aluminium hydrosilicate material, a silica-alumina molecular sieve zeolite, a silica-free alumina and a sulphonated perfluorinated resin. The process is particularly suitable for the preparation of methyl 4-oxocaproate by the addition reaction of acetone to methyl acrylate.
