Patent FR-2269803-A1 (FR)
Title: Male connector or electrical plug - has ratchet which grips cable entering plug and plug is not demountable
IPC: H01R13/502
Filed: 1975-04-30
Abstract: The two pin electrical plug is intended for applications where it is not intended that the plug should be dismantled, and the mechanism of the plug is designed to simplify the assembly and final protection and insulation of the end of the cable. The connector is made up of an encloseable supporting piece on which are mounted the plug pins over which is the cap through which the supply cable is fed. This has a section which grips the cable by peripheral pressure causing elastic deformation. This section also carries a threaded section over which the conically shaped cable entry guard is fitted. The mating of this cap to the body is secured by a ratchet effect.
Patent FR-2271573-A1 (FR)
IPC: G01N30/74
Filed: 1975-05-15
Abstract: The present invention is a liquid chromatograph comprising a chromatographic column; means, including a pump, connected to the input of the column for injecting a sample under pressure into the column; and a detector system, including an optically transparent flow cell and a connecting means connecting the flow cell to the output of the column. The connecting means is in thermal contact or at least thermal equilibrium with the flow cell for a sufficient length so that any liquid passing through the connecting means comes to thermal equilibrium with the flow cell before entering the optically transparent flow cell.

Title: Electron discharge equipment with beryllium oxide on electrode - in non-emitting zone, preventing stray electron emission
IPC: H01J43/22
Filed: 1975-05-16
Abstract: In electron discharge equipment, consisting of a number of electrodes arranged so that they enter into reciprocal action with free electrons, one of the electrodes has an emitting surface zone for emitting free electrons and one a surface zone from which emission is not desired, the surface of the second zone consists of BeO. This second zone pref. is kept at such a potential that emitted electrons flow from this zone to another electrode. The system is used esp. in photomultiplier tubes. Stray electron emission is prevented.

Inventor: ANCILLOTTI F
IPC: C07C43/04
Filed: 1975-05-20
Abstract: Methyl tert-butyl ether is prepared, and a stream of hydrocarbons containing isobutylene is freed therefrom, by reacting the isobutylene with methanol in a two stage process wherein, in the first stage, a stream of hydrocarbons containing isobutylene and methanol is fed to a primary reaction zone where the isobutylene and methanol partially react in the temperature range of from 50 DEG  to 90 DEG C and at a pressure of from 10 to 30 atmospheres in the presence of a catalyst to form methyl tert-butyl ether which is separated by distillation from the residue of isobutylene and methanol and all other hydrocarbons in the feed stream, and, in a second stage, the residue of isobutylene and methanol and other hydrocarbons is fed to a secondary reaction zone where the residue of isobutylene and methanol react in the vapor phase, at a temperature in the range of 60 DEG  to 100 DEG C and a pressure of from 15 to 40 atmospheres in the presence of a catalyst consisting of an acid ion exchange resin, to form the balance of methyl tert-butyl ether which is recovered by distillation to leave a balance of other hydrocarbons practically free from isobutylene.

Title: Continuous casting in rotating magnetic field - which applies centrifugal force on molten metal, producing high quality round billets
Inventor: ALBERNY ROBER
IPC: B22D11/115
Filed: 1975-11-03
Abstract: Round products are made by electrorotative centrifugal continuous casting, where the molten metal is injected into a cooled mould in which the liq. metal is rotated by a turning magnetic field. The partly solidified billet ie extracted from the mould. The novelty is that the motel metal is injected into a zone situated between 2 cm from the mould axis and 1 cm from the mould wall. The molten metal is pref. injected in a direction parallel with the axis of the mould, and esp. at the middle of the radius of the mould. The process is esp. suitable for casting round billets employed in the mfr. of seamless tubes, i.e. which to not possess a welded seam, where it is pref. to obtain a high quality surface and core fre from fissures or inclusions, and also to avoid oval billets which create problems in rolling.
Patent FR-2331737-A1 (FR)
Title: Pipe seal for accommodating misalignments - has resilient ring of non-uniform section providing sealing and overload support
Inventor: BRAM GEORGES EUGENE
IPC: F16L21/03
Filed: 1975-11-12
Abstract: The pipe seal comprises a resilient element situated in a groove in the inner surface of an outer pipe end (E) and engages a smooth cylindrical outer surface of an inner pipe end. The element is a ring whose cross-section, when free, is flat (5) with a bulbous enlargement (4) at one end. When the inner pipe end is inserted into the seal, it slides past the flat portion with a clearance (8) and then compresses the bulbous portion. Sealing is effected by the compressed bulbous portion, the flat portion providing back-up support in case of overload or misalignment of the pipes.

Title: Small dimension film winding system for cine camera - has film winding axes sliding in slots as dia. of film on spools changes
IPC: G03B17/26
Filed: 1976-03-08
Abstract: The cine film camera winding system uses two spools (2, 15) situated in the same plane. The free space between them, due to the reduction in diameter of the feed spool (2) is progressively occupied by the takeup spool (15) whose diameter increases. The two spools are placed on axes which can be displaced along slides (3, 24). The directions of these slides are not the same nor parallel. The slide (3), in which the feed spool axis is located, is rectilinear. The slide (24) in which the axis of the takeup spool is located, has the form of an annular section. The geometric centre of this slide (29) is that of the gearwheel (13) which drives the pinion (23) on which the spool axis is mounted.

Title: Electric line forming intruder deterrent - has periodically switched low voltage applied across capacitor and and transformer with output connected to exposed line
IPC: G01R31/50
Filed: 1976-04-23
Abstract: A source of supply voltage (1) is connected to a resistance (2) and the first winding of a transformer (5). The second terminal of the winding is connected back to the supply via a switch (4). A capacitor (3) is connected in parallel with the primary winding of the transformer.

Title: Compensation for torsion in fine wire or tube - uses motor driven disc controlled by magnetic sensors to control torsion in medical implant
IPC: G01D5/251
Filed: 1976-06-11
Abstract: Compensation for the torsion of a conduit of reduced rigidity is provided by a compensation disc in response to amounts of movement sensed by magnetic detectors. This compensation is applied to tube or fine wire conduit inserted into living subjects. A tube (2) subjected to torsion enters a torsion compensator where detectors sense torsional movements. The detectors comprise magnetic or metallic segments (9, 12) in movable central discs (8, 11) attached to the tube by tubular sections (20, 22). The magnetic segments operate flexible blade switches (1', A) in fixed peripheral sections (10, 13). A calculator determines rotation of a motor (18) from detector signals to turn a toothed disc (14) attached (16) to the tube.

Title: Electroluminescent monocrystalline gallium nitride semiconductor - with partially compensated layer below fully compensated active layer
Inventor: JACOB GUY
IPC: H01L33/00
Filed: 1976-09-06
Abstract: Electroluminescent semiconductor is based on a monocrystalline substrate with an n-GaN layer; an active GaN layer doped with a doping element for the formation of acceptor impurities at least completely compensating the natural donor impurities; a surface electrode in contact with the active layer; and also provision for contacting the n-conductive layer. Improvement is that (part of) the n-conductive layer, which is parallel to and bounds the active layer, is doped for less than complete compensation of these doping elements, the net concn. of the resultant impurities is small (pref. of the order of tenths to millionths) w.r.t. the concn. of natural impurities and these are almost homogeneous in the stated part of the layer. The net concn. in the material can be varied during epitaxial growth and more accurate and easily control is possible.
