Title: Variable trimmer resistor with miniaturised adjuster - has wiper frame set at acute angle to longitudinal axis and exerting contact force
Inventor: HUELLWEGEN JOSEF
IPC: H01C10/38
Filed: 1978-11-08
Abstract: Variable elongated resistor has a maniaturised adjustment device in the longitudinal direction. It is used as a trimmer, connected in series with a fixed resistance on a printed circuit board. It will therefore not require any additional space sideways-on and will therefore not occupy a greater area than an ordinary fixed resistor. It is made with a wiper frame (5) which can be adjusted along the long longitudinal direction of the resistor. The wiper (6) is in contact with the resistance track. The frame is at an acute angle with the body of the resistor, and will therefore exert a force in the sliding direction. It can be made with a fixed section not contacted by the wiper and a variable section to give a very high tolerance. The variable section can be made up of several sections connected in series.

Patent DE-2912640-A1 (DE)
Inventor: WALTHER RUDOLF
IPC: G01B5/22
Filed: 1979-03-30
Abstract: A measuring instrument (12) for measuring curvature, in particular on a spherical surface, is specified, in which the travel of a feeler (8) is fed to a small computer (11) via an analog-to-digital converter (9). The small computer optionally displays the radius (r) of a workpiece (1) or the deviation of the actual value of the measured radius from a prescribable desired value. Spacing limiters (6, 7) having different spacings can be selected for different ranges of radius. Instead of linear spacing limiters, it is also possible to use tips with spherical contact points or measuring rings. This measuring instrument is suitable for simple and quick determination of radii of curvature, in particular on workpieces of complicated shape and on workpieces having spherical or cylindrical surfaces. It is possible to measure both outside radii and inside radii. When it is set up on a planar support, the spherometer is suitable for thickness measurement. <IMAGE>

Title: Concrete wall construction shuttering panel connection - involves tension anchors plugged through rubber, or other elastic strips at joints
IPC: E04G17/00
Filed: 1979-05-18
Abstract: Panels are detachably connectable to form the inside and outside walls of the shuttering for erection of concrete walls. Tension anchors are inserted through individual panels, to hold them firmly at a space required for the wall thickness, and to absord pressure forces from the concrete cast inside. The points of abutment between the panels are formed by strips (12, 13) made of rubber, or similar elastic material, and the anchors (8) are plugged through these. Strips can be made up from two separate strip pieces, each joined to one panel, with anchors inserted between them. This provides good sealing at joints, and easy assembly and cleaning.

Title: Pressure transducer for brake light systems - with resistor in diaphragm for transistor contact operation
Inventor: TRITT GERHARD
IPC: G01L19/12
Filed: 1979-08-10
Abstract: An electro-mechanical pressure transducer, esp. for use in the brake lamp system of motor vehicles, uses a diaphragm to separate a pressure chamber from a contact chamber. The diaphragm is a hollow solid with a rotational symmetry and has in the centre a pressure-dependent resistor, pref. silicone rubber or PVC, contg. a filler. The pressure of response urges the resistor against two contacts, one connected to the base of an amplifying transistor and the other to its collector and to one of the plug pins.
