Title: Motorway distress light power supply with telephone - has cable with terminals into which motorist can plug his distress warning light
Inventor: BARTOLEIT LOTHAR
IPC: H04Q5/02
Filed: 1974-02-09
Abstract: The telephone network of the motorway or other major road has terminals into which distress lights can be plugged. The telephone network consists of a transmission line interrupted along the motorway by transformers at each telephone point. A dc. supply is fed into a centre tap of the first transformer at one end of a section of the system. At the first telephone point down the line, the two windings of the associated transformer are connected, through centre taps via a circuit consisting of a back to back zener diode arrangement in parallel with the distress plug terminals. This is repeated down the line until the last point where the centre tap goes to another dc. supply. A distress warning light plugged in can thus take a voltage up to the zener voltage.

Title: Pressure water heater with fibreglass reinforcement - has reinforcement held in place by foamed insulation within casing
Inventor: SCHIEDAT HEINZ DIPL ING
IPC: B29D22/00
Filed: 1976-02-10
Abstract: A water heater has a blow moulded inner liner (1), reinforced to make it pressure resisting by glass fibres (6) wrapped spirally round it. The fibres are fixed to the liner in a few isolated places only (7, 8, 9) by means of a plastic composition applied over them in these places. In addition or alternatively they are held against the liner by a foamed plastic thermal insulation (11) which is injected into the space between the liner (1) and a rectangular outer casing (10). This method of construction cheapens manufacture and prevents undesirable odours from the plastic impregnating the glass fibres and contaminating the water in the container. The liner (1) can have thickened sections (2, 3) at top and bottom to which the fibres are attached.

Title: Seat belt take:up mechanism - has spool rotation limited to one turn after fitting using manually operated clutch to allow adjustment
Inventor: WOLFF HANS-DIETRICH
IPC: B60R22/44
Filed: 1976-06-15
Abstract: The automatic seat belt take-up mechanism has a manually operated clutch which allows the belt to be pulled out before use and then allows a limited slack when the clutch is engaged. The mechanism consists of spool (2) on axle (1) with gear containing wheels (3, 4, 5, 6) on its extended part producing a rotation of wheel (6) which is only a fraction of that of the spool. Wheel (6) and clutch disc (7) are rigidly connected with counter disc (8) on the axle. The disc (8) also carries a plate (9) with lug (10) on its outer part, engaging with stop (11) on the housing (12), when in corresponding axial position. When the belts is pulled out from its unused position the axle rotates the clutch disc, but as the clutch is not engaged, disc remains stationary and the belt can be pulled out against the resistance of spring. When the belt is fitted the hand lever and cam is operated. The discs are in engagement and when further pull is exerted on the belt, plate (9) can now perform only a limited rotation of about 360 degrees, whereby lug (10) leaves one side of stop (11) and comes to rest on the other side.
