Title: Collectorless permanent magnet motor - uses induced voltages in stator windings to determine rotor position for obtaining commutating signals
Inventor: SCHALK KARL ING GRAD
IPC: H02P6/182
Filed: 1980-09-30
Abstract: The motor has a permanent magnet rotor and four-stator windings (W1-W4) spaced apart by 90 degs. electrical and each lying in series with a controlled electronic switch (V1-V4).

Title: Inhibiting oxidn. of copper film on ceramic - e.g. ceramic capacitor, by exposing it to halo:hydrocarbon
Inventor: SENDA ATSUO
IPC: C04B41/52

Patent DE-3039819-A1 (DE)
Title: Heat sensitive sensor and alarm system - uses spherical and plane mirrors to obtain scanning field of 90 degrees and detect heat -emitting body
Inventor: WETZLER GUENTHER
IPC: G08B13/193
Filed: 1980-10-22
Abstract: The alarm system consists of a detector element having its sensitive surface uppermost and horizontal, the section which receives the infra red radiation being very small. On the one hand, a sharp beam limit is then required, but on the other hand, it allows the element to have a very small heat capacity. Only in this way, can it act satisfactorily to small changes in heat radiation, such as a human body some distance away would cause. A spherical mirror is arranged to produce a collecting-sensing zone with the detector at its focus. To divide this zone into individual zones (11,12,13), flat mirrors are placed behind the detector element, forming sector shaped dead zones from which the three discrete sensing zones arise. The plan (flat) mirrors also create additional zones, so that a total angle of about 90 degrees can be monitored.

Title: Practice wall for ball games
Inventor: SANTOS GUSTAVO
IPC: A63B69/00
Filed: 1981-02-19
Abstract: A practice wall for ball games has a front side which is uniformly curved at least about a single, vertical axis, and is preferably constituted by a curved, flexible plate which is secured to a solid wall of a building by supports which are adjustable in respect of their length. By appropriate adjustment of the lengths of the supports, the wall can be pivoted both about a vertical axis and about a horizontal axis, and its curvature can also be modified within certain limits. This curved practice wall has the advantage that a ball ejected from the centre of the curvature is always, irrespective of its point of impact on the practice wall, returned to the centre of curvature, so that the practising player does not waste time on collecting the ball.

Title: Device for the delayed control of an output signal as a function of a control signal
Inventor: WALLISCH FRITZ ING GRAD
IPC: F15B21/02
Filed: 1981-02-28
Abstract: A pneumatic device (10) is proposed in which an output signal at the A-connection (23) is controlled in a delayed manner relative to an input signal at the Z-connection (12). The Z-connection is connected to a control connection (17) of a manipulating valve (18) via a choke point (14) and a volume (15). In this arrangement, the volume can be vented to the atmosphere via a rapid-vent valve (14) which is influenced by the control signal. Even if there is a long control line at the Z-connection (12), the rapid-vent valve (27) permits rapid re-setting of the manipulating valve (18) and makes the device (10) ready to operate again. <IMAGE>

Title: Machine for tying round packaged products
Inventor: SCHMID HELMUT
IPC: B65B13/34
Filed: 1981-05-27
Abstract: Provided in a manually operable machine for tying round packaged products is a closing device having an eccentric-actuated ram (34) at the lower end of which an exchangeable press body (46) is held by means of a spring-actuated catch ball (56). The underside of the body (46) has a pressing face (40) and a crimping face (42) for crimping round a lead-seal leg. When narrower or wider bands are to be processed in the machine for tying round packaged products, other lead seals are also required. For this purpose, the ball (56) of the catch device is pressed into the ram and the ram body (46) is removed downwards and replaced by another body which differs from the body (46) in a different design of the working and crimping face, but which has an inner cross-section fitting onto the lower end of the ram. In the new machine for tying round packaged products, the counter bearing face for the lead seal on the housing bottom is also formed on an exchangeable sliding body which is held in its position by a similar catch device. <IMAGE>
