Title: Dazzle-free headlights - using several coloured lamps to provide a white beam for driver only
Inventor: LEPPER WILHELM DR ING
IPC: F21S8/10
Filed: 1973-06-07
Abstract: Several lower powered headlamps are arranged along the front of the car. Each is fitted with a coloured filter and is directed over the same area on the road.

Title: Blow moulding thermoplast using bag around blowing mandrel - to distribute pressure and reduce risk of blowthrough
Inventor: FARRELL JOHN JEROME
IPC: B29C49/44
Filed: 1973-09-22
Abstract: An injection blow moulding apparatus has the blowing mandrell surrounded by a permanent flexible bag, onto which the molten plastics is sprayed; the mandrel together with bag and thermoplastic blank on the bag is then transferred to a blow mould where the bag is inflated, bringing the blank into contact with the inner face of the mould. The bag is pref. of an elastomer resistant to the injection and blowing temps. The open end of the bag is clamped at the base of the mandrel. The uniformity of moulding achieved enables risk of blow through to be considerably reduced, which in turn enables thermoplastics to be used at a lower temp. approaching the crystalline point.
Patent DE-2400624-A1 (DE)
Title: Burglar alarm for cars - has circuit breaker with hydraulically retarded action for switching off alarm after interval
Inventor: TEPOEL WALTER
IPC: B60R25/10
Filed: 1974-01-08
Abstract: The alarm, when set off, continues to operate even after repeated attempts to close the door or boot lid, by the opening of which it has been switched on. Regulations however do not permit the acoustic alarm to operate infinitely. Gear which switches off automatically after some time by electronic devices is costly and the time setting prone to variations due to ambient temperature fluctuations. The present arrangement uses a solenoid-type circuit breaker with a fluid-retarded action, provided with fluid having a flat viscosity curve. The device is fitted into the main circuit, hereby being independent from the happening within the auxiliary control circuit hitherto used.

Title: Pneumatic launcher toy for streamers - deformable plastic air chamber and funnel shaped barrel
Inventor: KANEKO HITOSHI
IPC: A63H33/18
Filed: 1974-06-19
Abstract: The toy is designed to propel coils of streamers, coloured confetti and folded paper hats etc., whilst making an explosive popping sound. The air chamber is drum shaped with flat elastically deformable sides and a flat base. The funnel shaped barrel is joined to the air chamber by a stiff collar with an internal concave groove whose lower rim has a smaller dia. than the upper rim. A spherical plastic foam bullet is wedged into the collar groove. The barrel is packed with the streamers and closed by a thin paper disc held in a groove near the outer end. Sudden compression of the air chamber by finger pressure "fires" the launcher.

Title: Control system for drier installation - has drip device and link electrode brought into contact by a water drop
Inventor: MEISNER ALFRED
IPC: F26B25/22
Filed: 1974-06-28
Abstract: A control system in partic for a dryer has a drip device (1) in the form of an electrode with a link electrode (5) below it.

Title: Motor controller for data store drive - comprising bridge cct with two variable voltage points
Inventor: MUELLER OTTO
IPC: H02P7/288
Filed: 1974-08-14
Abstract: The application is particularly to tape or capstan drives for digital tapes or cassette recorders in which the motor is controlled by a logic circuit via driving stages providing a digital control impulse sequence. The motor lies in one arm of a bridge circuit which has two mutually variable voltage points. The first point is governed by a symmetry controller and can provide a symmetrical supply voltage, for example - 12V from a unidirectional supply, 0-24V. The second point is determined by the motor speed controller. By relative movement of the two points the motor may run up in either direction and both acceleration and speed controlled to close limits without stringent power supply demands.

IPC: A63H29/22
Filed: 1975-06-26
Abstract: The mounting for motors on model electric trains consists of a single plastic piece (10) which cradles the motor on three sides. The device has two 'U' shaped clasps (1.5). These clasps are connected, at the top, by a lateral plate (20). At one end of this plate is a flap (26) on to which the electric motor is screwed. The shaft of the motor projects through a hole (28) in the flap. The free ends of the 'U'-shaped clasps (1.5) and the flap are connected by thin lateral struts (22, 23). On these struts are two pairs of catch hooks (4, 14). These catch hooks clip the device to the frame of the vehicle. The elasticity of the plastic in the thin struts allows the device to be fitted to or removed from the vehicle when required without tools and thus avoiding damage to the model.
