Patent FR-2546722-A1 (FR)
Title: Device making it possible to prepare the opening of shellfish such as oysters
IPC: A47G21/06
Filed: 1983-06-01
Abstract: The device which is the subject of the invention facilitates the opening of shellfish, such as oysters, by making it possible to make an opening at the periphery of the shell in order to permit the insertion of the blade 8 of the knife, with a view to cutting the adductor muscle, this opening being made by abrasion and not by crushing of the shell, thus avoiding any splinter formation which interferes with consumption. The device consists of a rotary disc 1 in the form of a rasp, against which a peripheral zone of the shell is pushed. A ventilating turbine associated with the disc 1 sucks up the shell particles thus produced and projects them into an air-permeable bag 17 which holds them with a view to their discharge. The device which is the subject of the invention may be used for domestic use and also in catering or the preserves industry.

Title: Multiple joining of very tightly spaced wires on contiguous substrates.
Inventor: KNEEZEL GARY ALAN
IPC: H05K3/36
Filed: 1983-06-22
Abstract: Method and device for the multiple joining of electrical circuits on contiguous substrates, in which there is provided a jumper 10 with high density protruberances, having mushroom-shaped contact protruberance stretches 14 raised up at the two ends of a flexible circuit.

Title: Pressure sensitive carburettor control
Inventor: STEVENSON DAVID LEE
IPC: F02M1/14
Filed: 1983-07-12
Abstract: The vacuum pressure regulator system is used, e.g. in a motor vehicle.  It has a housing (22) which contains a flexible diaphragm (30), which is urged by a spring (56) towards a flat end cover (34) and away from the end (50) of a central tube (48).  This tube is connected to a line (26) leading to the carburetter.  There is a valve element (44,46) which allows gas to flow from the inlet manifold to the control chamber (36) behind the diaphragm. There is a connection or line (24) leading from the control chamber to the inlet manifold, so that the pressure in the control chamber is equal to the manifold pressure.  The connection to the carburetter supplies the vacuum to operate an actuator for an air control valve upstream of the throttle valve.

Title: Multiple share plough width adjustment mechanism
Inventor: ALBERS HEINRICH
IPC: A01B15/14
Filed: 1984-08-29
Abstract: The tractor drawn plough with a line of ploughshares mounted on a beam, includes a linkage and drive which enables the width to be ploughed to be adjusted. Each share is mounted on an arm with a hinge so that it can be tilted about a vertical axis, altering its angle. The arm slopes at an angle to the direction of travel, and carries a piston and cylinder to adjust the angle. At the connecting end of the beam is an auxiliary tilting mechanism. This includes two swinging links connecting the beam to a swinging bracket connected to a cross, member behidn the tractor. One of these links is an auxiliary cylinder for length adjustments. The axes of these two links meet at an common point close to the cross member, and alignment can be altered by using alternative holes for anchorage bolts or securing devices.

Title: Case for protecting fibre-optic cable splices
Inventor: TALBOT LOUIS JEAN MARCEL
IPC: G02B6/44
Filed: 1985-05-23
Abstract: The invention provides a perfectly sealed housing having boards serving for the splicing of fibre-optic cables, the case nevertheless remaining entirely dismantleable in order to be easily replaceable in the event of deterioration and in order to facilitate work on the said boards. The protective case is constituted by two elements 1, 2 at right angles and by two flanges 5, 6. These elements 1, 2 comprises edges 7, 8, 9, 10 which are inclined at 45 DEG in order to permit better compression of the joint 14 with which they are equipped. Grooves are provided at their respective ends so that, after assembly, they hold the two flanges 5, 6 captive. At least one 5 of the two flanges 5, 6 ensures the sealed passage of the cables; in order to enable it to be replaced without touching the cable connection, it is formed by three separable parts - two end half-flanges and one intermediate flange - which, when they are assembled, form the openings 15 for passage of the cables. The invention finds application for the connection of fibre-optic cables of the video-communications network.
