Title: Vehicle safety belt releasing upon impact - utilizes tension under impact to effect rebound release of the mechanism
IPC: B60R22/32
Filed: 1973-07-11
Abstract: Safety belt uses a spring loaded longitudinally sliding plate to absorb impact energy and to recoil, whilst maintaining the normal unbuckling facility. A clasp box houses a longitudinally sliding rectangular frame which is sprung to the box wall and affixes permanently to the belt via a projecting member (B). Belt tension causes this frame to retract against the springs and so allow two attached pinned levers (E) to rotate into a position whereby under recoil they slide under and deflect a blade spring (G) thereby causing two chamfered studs (E) to disengage from the notched female belt tongue plate.

Title: Construction element connexion clip - has hole for bolt and is clipped over construction element
IPC: E04D3/36
Filed: 1975-04-14
Abstract: The length of the clip is greater than the width of e.g. an I-beam flange and the clip is installed in two stages. Initially the clip end with the longer return (12) is slid fully over one flange. Reverse sliding then moves the opposite clip end (13) tightly onto the corresponding flange. A cotter pin, bolt etc. through holes (121, 152) in the clip end with the longer return (12) then locks the clip in place. The clip hole (151) may be of a polygonal shape to prevent bolt rotation. A series of holes (121, 152) may permit the clip to adapt to different beam sizes.

Title: Dual internal combustion engine fuel supply - adding propane air mixture to petrol for reduced carbon monoxide in exhaust
IPC: F02M13/08
Filed: 1975-04-30
Abstract: An internal combustion engine using ordinary or five star-petrol as motor fuel has an additional supply of a mixt. of a combustible gas (propane) and air. This extra supply is utilised specially at low engine speeds during idling and for the starting period. A flange is arranged between the carburettor and the engine intake manifold. A bush has perforations for the admission of atmospheric air and others for a hose to a propane bottle. The propane admission is controlled by a solenoid valve which can be actuated by the ignition key or separately. This eliminates the emission of noxious substances with the engine exhaust which is particularly high in CO content at low engine speed. Existing engines with carburetors can be readily converted to the additional supply.

Finally the nut (16) which itself is of resilient material, and with a spherically faced (25) flange (21) above it, is secured by inserting a set of fingers (27) through the bush (23) so that their hooked ends (26) grip it. An alternative subassembly using a securing screw is shown.

Title: Corner stakes with widened lower ends - are compacted inside jacket column which is raised from ground
Inventor: LEITGOLD A E
IPC: E02D7/26
Filed: 1975-07-08
Abstract: The corner stakes have widened lower ends and are produced by forming a hole in the ground, lowering a jacket tube column (1) into the hole, introducing stake material into the column cavity from which the earth has been removed, and compacting the material pneumatically in the hole while withdrawing the column in hermetic sealing relationship. The stake material is first supplied in a quantity sufficient to form the widened portion, then the column is raised by a certain amount (h2) equal to the height of the material which has been introduced, then the column is filled with the remainer of the material of which the quantity is sufficient to form the pile shaft. The shape of the base is formed by vibrating the column while lowering it, and the shape of the shaft is formed by vibrating the column and applying compressed air while reciprocating the column longitudinally.

This is forced forwards by a set of three cylinders powered by a system of jacks, the cylinders being operated sequentially to move telescopically. Between the head and the first cylinder is a ring of smaller guide jacks. A layer of clay is injected through passages along the first cylinder around the second cylinder, when the first cylinder has been forced forwards by the main jacks. A layer of concrete is injected around the third cylinder, and the cylinders are then progressively advanced.

Title: Detection of leakage current to earth - uses differential current transformer whose core is saturated by leakage current
Inventor: CANONNE PAUL
IPC: H02H3/33
Filed: 1975-08-11
Abstract: The differential current transformer circuit with adjustable sensitivity detects leakage or fault currents to ground where the supply may have both d.c. and a.C. components. In the case of a single phase supply (2) both lines are brought in to form two identical primary windings (7, 8) on a preferably high permeability, low saturation level toroidal core (3). An orthodox secondary winding (11) feeds a very high sensitivity relay (12) which can switch out the power supply. A fourth winding (9) provides an adjustable alternating flux in the core such that a fault current taking the core into saturation provides the relay with sufficient power to operate it.

Title: Staple fibre chopping unit - having even number of cutting blades on cutting head with angular pitch and variable intervals(NL-9.3.76/BE-8.3.76)
IPC: D01G1/04
Filed: 1975-09-05
Abstract: Appts. for chopping cable strands of continuous synthetic or semi-synthetic filaments, into staple fibres, has an even number of cutting blades located at variable intervals of arc on the cutting head. The cutting surfaces of the blades alternate by an angle of pitch to the rotating plane of the cutting head to cut the cable strand at an angle either side of 90 degrees. the sitting disc for the location of the blades being suitably structured. The system ensures that a predetermined variation of staple fibre lengths are cut from the same cable strand to give a controlled blend of lengths and ratios in the mixture of fibres produced.
