Title: Method and device for measuring the ignition timing advance angle
Inventor: MAYER GERHARD
IPC: F02P17/10
Filed: 1981-04-23
Abstract: A method and a device for measuring ignition timing advance angles in an internal combustion engine are proposed, in which the ignition advance angle signal is formed from a reference signal and a dwell angle signal. If the ignition advance angle signal exceeds or falls below a predetermined value another pulse of the dwell angle signal is singled out and compared with the reference signal and the ignition timing advance signal formed from this. It is therefore not necessary to scan the signal for the ignition point after the ignition distributor, there being a risk that the signal is not scanned on the correct lead in relation to the reference signal. Rather, the signal can be scanned ahead of the rotor arm, the correct dwell angle pulse being picked up by a corresponding circuit arrangement. Instead of the dwell angle signal, any other signal of the same frequency can also be used which contains the ignition point.

Patent DE-3125041-A1 (DE)
Title: Anti-theft device for round, telescoping implements, in particular air pumps for two-wheelers
Inventor: JOHANNSEN HANS-WERNER
IPC: B62J11/02
Filed: 1981-06-26
Abstract: The invention describes an anti-theft device, in particular for bicycle air pumps. The device is composed of in each case one pin, which pins are arranged aligned in the axial direction with the sleeve of the air pump. The device furthermore includes a set of rings comprising at least two rings which are linked together in the axial direction but can be rotated relative to one another and surround the sleeve. On its inside surface, each ring has an annular groove using which the ring can be rotated, in the securing position of the set of rings, on the pin allocated thereto, as well as an axially extending rivet. In the securing position, the set of rings bears against the grip of the air pump and prevents an axial displacement of this part as long as the rings of the set of rings are not in a position relative to one another in which their inner axial grooves are in alignment with one another and coincide with the pins. Markings are made on the rings and on the sleeve of the air pump which make it possible to find that position in which the inner axial grooves and the pins coincide.

Title: Self-extending tape-measure of synthetic resin and process for the production thereof
Inventor: NAGASAWA TAKASHI
IPC: G01B3/10
Filed: 1981-08-14
Abstract: A self-extending tape-measure which is usually known as a convex tape-measure was hitherto made exclusively of steel, however a steel tape-measure is not only subject to rusting but is also dangerous when used in the vicinity of electrical wires because of its good electrical conduction. To eliminate the aforementioned disadvantages, the invention provides a self-extending tape-measure of resin which is produced in that a tape material comprising mutually crossing fibres is impregnated with a large quantity of heat-curing resin, the tape material is bent in the transverse direction to form an arc in cross-section, so that the arc takes up a third to three-quarters of the entire circumference of the circle described by the extension of the arc and the tape material is heated to cure the resin and to produce the curved shape.

Patent DE-3136970-A1 (DE)
Title: Projector
IPC: G03B21/132
Filed: 1981-09-17
Abstract: The invention relates to a projector which has above the plane of the original a device head with a deflecting mirror and a lens held on a lens holder. It can frequently be difficult or impossible for the projector or the projection screen to be arranged respectively at a level such that the beam path reflected from the reflecting mirror can extend precisely horizontally. If, however, the beam path is directed obliquely upwards or downwards, the result is an uneven image sharpness (definition). However, even in such a case the image sharpness can nevertheless be optimised when, in accordance with the invention, the deflecting mirror is arranged capable of pivoting about a horizontal axis, and when the pivoting position of the lens relative to that of the deflecting mirror is variable. The first step is to set the deflecting mirror such that the image is located completely on the projection screen. The image sharpness is subsequently optimised by appropriate pivoting of the lens.

Title: Radio direction finder
Inventor: SCHMENGLER ECKHARD DIPL ING DR
IPC: G01S3/38
Filed: 1982-03-27
Abstract: So that a monopulse radio direction finder can be provided both with a simple unambiguous analog and a digital indication of the bearing angle, two oppositely directed rotating-field antenna patterns are derived from an antenna system via a network, which patterns in each case correspond to the simple angle of incidence, and, at the same time, an azimuth-independent reference signal is generated by a separate omnidirectional antenna or directly from the antenna system generating the rotating-field antenna pattern, and from these signals, the angle of incidence is directly determined by determining the phase difference by means of known analog and/or digital evaluation in an evaluating device.

Title: Method for producing multicolour copies in a multicolour copier, and device for carrying out the method
Inventor: KNECHTEL WILHELM
IPC: G03G15/01
Filed: 1982-05-08
Abstract: Multicolour copier, in which latent electrostatic images of the individual colour separations are produced simultaneously or sequentially from an original on in each case one process cylinder assigned to a colour separation. The latent electrostatic images of the colour separations that are produced on the process cylinders are developed into powder images using assigned colour powders. A copying paper passes by the process cylinders at constant speed and reaches the process cylinders at temporal intervals. In order for the powder images of the individual colour separations to be transferred to the passing copying paper in the correct register, the process cylinders have a spacing from one another such that in each case the powder image of a colour cylinder has then reached the transfer zone. In order to prevent the powder images or the latent electrostatic images of the individual colour separations from moving over onto the process cylinders via the transport belt for the copying paper, without image transfer taking place, the latent image is first developed when it can subsequently be transferred immediately. In the event of simultaneous exposure of the process cylinders the subsequent process cylinders are brought into the active position with a jump (by a "skip"). The transport belt can advantageously be swivelled away from the process cylinders during the "skip". <IMAGE>
