Inventor: SCHAELING WOLFGANG
IPC: G01R31/58
Filed: 1975-08-21
Abstract: The preformed cables testing device is esp. suitable for motor vehicle types. Each wire is automatically and consecutively tested for continuity. When a wire is found to be incorrectly connected or broken, testing is stopped and the wire number displayed. A store holds each wire with its connecting and branching points in the cable. The stored wire can be called by its number and visually displayed. The cable (10) is laid on the mounting blocks (11) on the testing board (12). The testing device (13) examines each wire in turn while the associated number is displayed in the window (14). The indicator window (16) of the store (15) lies directly in front of the operative.

Title: Web splicer control device - which is triggered by counter signal produced by stopping pulse applied to repeatedly counting counter for new web roll
IPC: B65H19/18
Filed: 1976-05-28
Abstract: Control device for the web end splicer includes a sensor which is responsive to a sensing mark (I) on the periphery of a rotating replacement web roll to trigger a time delay responsive to the actuating time of the splicer, to enable after the elapse of the actuating time a forward counter. Latter is settable to a count corresponding to the sum of the distances between the sensor and the splicer and an acceleration path. Counter is set to aero on reaching the count, the count being repeated until it is stopped by a pulse produced by the passage of the mark (I) in front of the sensor. Subsequently the forward counter or a reverse counter which is also triggered by synchronous speed signals counts back from the new count to zero to produce at the zero count a control signal for the splicer. Splicing is tiggered fully automatically.

Title: Outside filter for plastic drain pipe - has strip wound during pipe transfer through rotating drum to form uniform layer
Inventor: OLTMANNS HEINRICH
IPC: B65H81/06
Filed: 1976-08-27
Abstract: The plastic drainage pipe is provided with an external filtration layer which is held in position by a helical wound tape. The pipe moves through the centre of a rotating filter application tube and then through a winding station where the tape is installed.

Title: Solar energy absorber with flat transparent cover - having angled baffles between cover and base preventing convection losses
Inventor: STANGE JOACHIM DIPL PHYS DR RE
IPC: F24S10/75
Filed: 1976-10-11
Abstract: The air space between the flat cover and the energy absorber of a solar cell has angled baffles which minimise air convection currents. The lessened degree of air circulation gives a lower loss of heat by convection to the top cover, and hence higher overall efficiency of the cell. The solar cell has a transparent flat top cover and a heat-absorbing blackened collection layer, the latter having inter-connected heat transfer medium flow pipes for removing the absorbed energy. Between the top cover and the collector there are a number of transparent intermediate baffle walls, angled to the cover and the absorber, which prevent recirculation of the heated air in this air space back to the top cover plate.

Title: Vehicle light warning circuit - gives audible and visual signals when lights are required
Inventor: EVERS JOHANN
IPC: B60R16/023
Filed: 1977-02-08
Abstract: The vehicle warning circuit gives visual and audible warning signals when the surrounding light intensity is such that lights are required. The warning signals cease when the lights are switched on and recommence when the ignition is switched off to avoid storage battery discharge. The circuit is connected to the ignition switch (15) and the light switch (56) and contains a low ohm photo-electric resistance LDR and a Schmitt trigger consisting of resistances (R1-R5) and two transistors (T1-T2). The Schmitt trigger becomes conductive when environmental light falls below a certain intensity to activate the warning signals (LED and LA) via an amplifier transistor (T5).
