Title: Internal combustion engine exhaust system and silencer - uses tubes with multiple bores to cool exhaust gas
Inventor: LEISTRITZ HANS KARL DR
IPC: F01N13/16
Filed: 1977-10-26
Abstract: A silencer forming part of the exhaust system of an internal combustion engine consists of two concentric tubes (51, 52). These tubes are joined by radial walls (55) which extend longitudinally so that the annular space between the tubes is divided into a number of separate compartments (5).

Title: Composite door or window handle - has stretched counter-piece over hollow metal profile on metal cored plastics base
Inventor: EIGEMEIER WILLI
IPC: E05B1/00
Filed: 1978-08-18
Abstract: A hollow metal profile piece is thrust onto the open end of the plastic base unit of the door hadle or window grab, one side being additionally held by a covering cap. The base unit, made of thermoplastics material, contains a metal core (6) which largely absorbs any forces that occur. The hollow profile piece (2) making up the length of the grip is covered at the end face by the base unit (1), and by a counterpiece (3) stretched to lock into this. The axial lengthways stretching provides compact connection between base unit, hollow profile and counterpiece. This enables considerable lever action forces, such as those occurring with lift and slide doors, to be transferred, and permits firm ounting of a grab component with a plate.

Title: Motor with mechanically wound drive - has tension band stretched between pins arranged between discs forming drum on shaft
Inventor: SPEER ANTON DIPL ING
IPC: F03G1/00
Filed: 1978-11-17
Abstract: The motor has two discs (6, 7) axially separated from each other on a shaft (1). The driving mechanism is contained between them. A tension band (26) is stretched over pins (21, 23, 24, 25) one of which (21) is fixed to one of the discs (7).

Title: Permanent magnets for holding drawings or notices - have spigots and recesses enabling storing stacks when not in use
Inventor: HEBEL ULRICH
IPC: H01F7/02
Filed: 1978-12-12
Abstract: So that small permanent magnets (1) which are used for holding notices or drawings on a board, or for display or indicating purposes, can be conveniently stored when not in use one side is formed with a spigot (2) and the opposite side with a corresponding recess (3). This enables stacking the magnets in columns. It also enables a number to be held easily in one hand. Alternatively, if the magnets have to be provided with caps, e.g. colour coded for identification, the cap has recesses on each side, one deeper than the other. The magnet disc is permanently fitted into the deeper recess and protrudes beyond it. In this way a similar stack of magnets can be built.

Title: Non-contact sensing of magnetic coding - has permanent magnet field completed by coding to generate pulse from sensing stage
Inventor: HERMSTEIN WOLFGANG DR ING
IPC: G06K7/08
Filed: 1978-12-13
Abstract: Non-contact sensing is of coded data cards using magnetic markings in bar code format is achieved using a passive device based upon permanent magnets. The sensor has a 'U' shaped permanent magnet(8) with non magnetic blocks(8, 9) separating it from a Wiegand conductor(11). This conductor has a soft magnetic core(12) with an outer layer(13). The conductor is magnetised in a selected direction(14). Separate permanent magnets(17, 18) complete the unit. When the coded bar(3) of magnetic material is passed over the sensor a current is induced in the coil(20) that is part of the Wiegand conductor. The output generated is in the form of a positive pulse from the leading edge of the coded element and a negative pulse at the trailing edge.

Title: Contactless optical measurement or filling material level - using optical receiver detecting max. reflection from material exposed to rotatable light sources
Inventor: BENZ KARL
IPC: G01F23/292
Filed: 1979-03-07
Abstract: A device measuring the level of filling material in containers gives a simple contactless measurement independent of material density, dielectric constant or temp., container shape, and air disturbance caused by material filling or emptying. An optical receiver (24) fixed above the material (12) receives light from sources (14, 16) rotatable about horizontal axes by reflection from the surface of the material. The level of the material is determined from the angular position (beta) of the source w.r.t. a reference line (34) for which the receiver detects max. reflection and the horizontal separation (a/2) of source and receiver. The receiver optical axis (32) is vertical and the source has an associated angular position transducer. The source can be fixed to enable a limiting level to be detected.

Title: IC engine power and condition monitoring of each cylinder - using combustion chamber pressure sensor and summer circuit integrating signal during gating period
Inventor: MAUSNER EBERHARD
IPC: G01L3/24
Filed: 1979-03-22
Abstract: A device monitoring the power of an i.c. engine exactly determines the power and condition of each cylinder whilst the engine is running without a major intrusion into the normal engine lay-out. This enables faults to be detected and eliminated before severe damage can occur. The pressure in one or more combustion chambers is converted by a sensor into an electrical signal. The signal is fed to a summer circuit which integrates the signal during a gating period. The summed signal is compared with a desired value. The summing circuit may receive its input from the sensor via: a differentiator, a peak value detector and/or a logarithmic circuit. Alternatively, several summing circuits may be used. Their outputs are passed to the comparator only under defined engine operating conditions.
