Title: Automatically positioned vehicle safety belt - has belt reel released when handbrake is on to permit opening of door with belt attached
IPC: B60R22/04
Filed: 1975-10-06
Abstract: The vehicle safety belt is automatically positioned and released as the occupant enters or leaves the vehicles. It comprises a housing on the body, containing a belt reel controlled by a spring and a ratchet wheel and pawl which has a cable connected to the handbrake.

Title: Friction coupling for two coaxial shafts - has hydraulic turbine for starting torque transmission with drive shaft disc located vanes for fluid pumping
Inventor: BEDUE ABAL JEAN HENRI
IPC: F16D33/00
Filed: 1976-01-26
Abstract: The hydraulic-mechanical coupling for two coaxial shafts has two sets of friction discs. Each set is in mesh with one of the shafts. The discs of the driver shaft also include vanes which pump a hydraulic fluid when they are rotating. Turbine blades on the friction discs of the driven shaft are thus rotated by the movement of the hydraulic fluid. when the speed of the two shafts is identical, a valve is opened so that piston clamps the two sets of friction plates axially together. Thus the two shafts are now coupled by mechanical means.

IPC: B60Q1/105
Filed: 1976-05-11
Abstract: Correction device for adjusting the position of a correction element as a function of the position of an information element where the device has a receiver fitted to the information element while a correction appts. has a correction element. The receiver has two chambers which are filled with a fluid and a gas. The two chambers are separated by a movable sealing element, whose position is controlled by a connected information element. Each correction appts. also has two enclosed chambers. These are completely filled with a fluid and separated by a movable sealing element, whose position determines that of the connected correction element. Each of the two chambers of one correction element is connected with one of the chambers of a receiving organ. The pressure loss on transfer of fluid through the connection between the chambers of the receiver and the correction organis large compared with that which take place when fluid is displaced in the part of the receiver organ chamber, which divides the gas volume from the correction.

Title: IR detector elements prodn. - uses IR sensitive plate on support with parallel channels and thickness reducing process with edge rounding step
IPC: H01L27/146
Filed: 1976-07-20
Abstract: Each produced infra-red detector element has a body of infra-red sensitive material with rectangular surface configuration. The body has on one surface spaced contacts of low resistance. The detector body is in the form of a plate secured on a support. In this plate are produced parallel channels to form strip-shaped parts. The thickness of the strips, preferably of cadmium mercury telluride, is reduced by etching and polishing. The curvature of the exposed longitudinal edges is obtained by further parallel channeling in a direction orthogonal to the first channels. Thus a matrix of almost rectangular detector elements are obtained. The contacting is provided by deposition of conductive material. Finally the elements, including their contacts are removed from the support.

Title: Servo assisted clutch operator - has gear lever interlocked with servo solenoid which also responds to impulse control at low engine speeds
Inventor: POLYAK D G
IPC: F16D48/02
Filed: 1976-08-27
Abstract: The servo assisted dry plate clutch is operated by a control lever driven by a servo controlled by a simple solenoid. The operation of the gear lever is interlocked with the solenoid. The solenoid is also activated by an impulse control to disengage the clutch when the engine speed drops to idling and prevents the engine from stalling.

Title: Ultrasonic wave sonde for subterranean investigation - is applicable in small boreholes giving high quality emission and detection
Inventor: POCHET REMI FRANCOIS
IPC: G01V1/52
Filed: 1976-10-29
Abstract: A sonde for ultrasonic detection which can be raised and lowered in a verticla pit shaft has an elongated housing presenting a longitudinal axis. Inside the housing there is an assembly for emitting and an assembly for receiving acoustic waves. The active parts of both the emitting and the receiving assemblies consist of >=1 washer of piezo-electrical material, the active face of which is perpendicular to the longitudinal axis of the housing, and is aligned to the active face of a mirror for reflecting acoustic waves. Each assembly is formed by a piezo-electrical washer fixed by its active face to a first mass of metal which is fixed in its turn to the housing of the sonde. The mirror is fixed to the first mass of metal, and a second mass of metal is fixed to the non-active face of the washer. The sonde is used in boreholes of small dia. and is designed to emit waves with a frequency of ten to several times ten kHz. A single frequency is emitted and the power can be adjusted by grouping the ceramic piezo-electrical elements under precompression.

Title: Retractable boring crown, esp. for sampling subterranean strata - allows cutter changes without lifting boring bars from hole
IPC: E21B25/04
Filed: 1976-12-01
Abstract: A device permitting the exchange of all or part of the cutter crown during boring, without drawing the train bars from the hole, has, at end of the train of bars, a cutting sleeve screwed on the outside of the sampling tube. This sleeve has four teeth with contacting angles allowing the crown to be locked and driven in the open position. The eight elements of this crown, of which there are two sets of four, have male sliders for the male elements and female slides for the famel elements with driving faces and limit stops. The dovetail slides have an inclination in the vertical plane and an angle in the horizontal plane so that when they slide four by four they can open or close the cylinder and, by means of the extractor holder screwed to the inside of the tube, take out or replace the crown. The female elements have their widest part axially downwards with the recesses for the driving teeth of the cutting sleeve. The male elements have the point of the engaging tooth high axially for engagement with the driving tooth. The male elements are connected to the extractor carrier by a tie bar retained in a tee slot with a stop limiting the end of the stroke. Arrangement makes it possible to change the cutters in the boring head for extracting a sample from a subterranean formation, without lifting the train of bars from the borehole.

Title: Biological liq. sampling instrument - has needle inserted in bottle through independent, movable sealing plug
IPC: A61B5/15
Filed: 1977-02-22
Abstract: The instrument allows the repeated taking of samples of biological liquids and blood in particular.

Title: Direct acting heat engine - has flexible membrane coupled to resonant spring mass system to maintain reciprocating action
IPC: F01K11/00
Filed: 1977-05-13
Abstract: A variable volume working chamber (1) is closed by a flexible membrane (9). A permanently open inlet (5) admit a gas obtained from a boiler into the chamber. The gas raises the membrane which is connected to a mass (7) and a spring (6). At the top of its stroke the membrane opens an exhaust valve (11) by means of a rod (13) from the membrane. The spring force then returns the membrane and forces the gas out to atmosphere. The natural frequency of the spring mass system (6, 7) is higher than the sonic velocity in the gas. This enables the oscillation to continue with the permanently open inlet (5). The gas pressure produced by the spring on the exhaust stroke opens a ball valve (17) forming an extra inlet.
