Patent DE-2421619-A1 (DE)
Title: Glass fibre reinforced wound pressure container - made by progressive ultraviolet hardening from inside outwards during winding
IPC: B29C53/84
Filed: 1974-05-04
Abstract: A method of making a glass-fibre reinforced article consists of impregnating the fibres, e.g. in unsaturated polyester, and continuously applying them, in one or more layers, onto a support; the final hardening stage for each strand is individually initiated by local ultra-violet irradiation as soon as it is applied, and is not completed until all strands have been applied. Preferably, the local UV irradiation is at the application point, and additives to the plastics ensure that the transformation from the gel phase to the hardened phase takes place at completion of the application of all strands. The total hardening time is reduced. In multilayer application, any cracks in lower layers are filled by unhardened material as the upper layers are applied. No separate treatment plant for hardening is necessary.

Title: Self loading tipper lorry - is fitted with loading skip which is pivoted about rear axis to lift loads into tipper platform
Inventor: LUTHER PETER
IPC: B60P1/48
Filed: 1974-10-05
Abstract: The rear of the special lorry is fitted with two hydraulically operated arms (1) which can pivot over the rear end about a transverse axis. The load surface is fitted with a large rectangular skip (7). For simple loading the arms are fitted with a chute (11) which can be swung down to ground level behind the lorry and filled with the load. The chute is then lifted and tipped into the skip. This enables breakable rubbish, e.g. bottles, to be loaded with a minimum of injury risk, after which they are broken when dropped into the skip. The skip can be raised by the arms, on chains, and tipped over the rear of the lorry to discharge the load. Smaller skips can also be carried, if required, and are narrow enough to fit inside the larger skip.

Title: Cigarette lighter which uses gas - has circuit for generating HV pulses for ignition using spark jumping gap
Inventor: GERSING EBERHARD DIPL PHYS
IPC: H03K3/57
Filed: 1974-11-25
Abstract: H.v. pulses are generated from an 1.v. d.c. voltage source and the circuit comprises an oscillating d.c./-a.c. converter which charges an ignition capacitor to a specified voltage level: when this level is reached, the capacitor discharges through a voltage stepping-up device. A flip-flop (5, 8, 7, 10, 9, 11, 4) always takes a certain first state when supply voltage is applied; it allows in this state the d.c./a.c. convertor (14-18) to oscillate, and is tripped into its second state by the ignition capacitor (21) discharge, or by a spark discharge in the spark gap (29), in which state the d.c./a.c. converter oscillations are stopped.

Title: Moving fibre cakes for fibreboard - scattering fibres on transport belt, compressing them with thin film of adhesive to form fleece, and removing to main transport belt
Inventor: METS ALBERT DE
IPC: B27N3/20
Filed: 1974-12-10
Abstract: Regularly distributed fibres e.g. for making fibreboard consisting of two outer layers of fine fibres on opposite sides of a central layer of coarser fibres, are moved by scattering the fibres at three places on a first transport belt for transporting towards a main transport belt, the first transport belt passing over a blade-shaped plate at the place where the fibres are delivered onto the main transport belt. The fibres forming the lower outer layer are compressed under a thin film of adhesive material, in order to form a fleece which can be moved from the first transport belt onto the main transport belt, without risk of tearing or deforming.

Title: Contactless output stage for AC switch - has unijunction transistor blocking thyristor until the control circuit is charged
Inventor: GEFFERT REINHARD ING GRAD
IPC: H03K17/725
Filed: 1975-03-07
Abstract: The contactless output stage, for and ac switch, consists of a thyristor or another semiconductor switch, controlled from a control circuit. At the beginning of each half-wave of the ac supply this thyristor (Th1) is turned off for a given time independently of its control circuit. During this time the supply voltage is used to charge the supply circuit (R6, T1, T2, R5, C1) for the thyristor control circuit. When the required control circuit supply voltage level is reached, the thyristor is unblocked and is free to be controlled from the control circuit. The thyristor is blocked for this given time by a unijunction transistor (T3).

Title: Tunnel support shield with lining tube - has overlapped friction reducing sheets with fluid sealed between tube and wall
Inventor: EBRECHT WILHELM
IPC: E21D9/00
Filed: 1975-10-08

Title: On:off switch of overhead projector - is repositioned to protect lens against inadvertent damage
IPC: G03B21/132
Filed: 1975-10-13
Abstract: The overhead projector has a horizontal screen, illuminated from below, whose image is projected through a lens (8) and reflected from a mirror (10) on to a wall. When the equipment is not in use, the mirror is folded down over the lens, to prevent dust settling on it.
