Patent DE-2837920-A1 (DE)
Title: Multiple probe distinguishing between oil and water layers - measures refractive, conductive, and capacitive characteristics and contains printed circuit board
Inventor: MUENNICH-DEBUS HERMANN
IPC: G01N33/18
Filed: 1978-08-31
Abstract: The multiple probe for distinguishing between different media esp. oil and water, lying one upon the other, is in the media with both its measurement planes immersed. It uses several different measurement methods, eg. capacitive, conductive, refractive index measurements etc. This ensures reliable determination of the media characteristics. It detects very thin layers, detects oil water boundaries even when very pure water is present, enables determination of when the probe is mainly in a medium or air, requires only short immersion times, and is insensitive to contamination. The electronic circuitry is mounted on a circuit board inside the probe. Refractometric measurements take place in a prism notch arranged at different angles. Capacitive and conductive measurement electrodes are arranged in the same or different measurement planes.

Title: Riveted joint for materials of different strengths - has stronger material deformed into rivet projection by punch and die
Inventor: HILLMER HERMANN
IPC: B29C37/00
Filed: 1978-09-27
Abstract: The joint for materials of different strengths is carried out in two stages. The stronger material (1) is placed over the weaker material (2) which is placed over a die (3). A punch (4) is pressed onto the stronger material and partly penetrates it, causing a projection on the undersurface. This projection pierces a hole in the thinner material by removing a small disc (5). The two pieces of material are placed on a domed tool (8) and the punch (4) is applied once more causing the projection (7) to spread outwards and form a rivet head.

Title: IC engine with air flow-controlled continuous fuel injection - has pump coupled to throttle to inject additional fuel during acceleration
Inventor: SARUTA MASAHIRO
IPC: F02M69/44
Filed: 1979-03-27
Abstract: The fuel supply system is intended for continuous fuel injection into an i.c. engine air intake (5).

Title: IC engine with turbocharger - has turbocharger controlled to maintain constant peak pressure to maintain efficiency at part load
Inventor: EMMENTHAL KLAUS-DIETER DR ING
IPC: F02B37/18
Filed: 1979-03-31
Abstract: The engine (8) has a supercharging compressor (3) in the air intake (1) which is directly coupled to a turbine (4) driven by the exhaust gases. Fuel is injected either individually into the separate cylinder inlets (6) or into the common manifold (7). The exhausts (10) from all the cylinders are taken through a common manifold (11) to a control valve (12). This passes the exhaust either to the turbine (4) or through a by-pass (15) directly into the exhaust outlet (14). The valve (12) is operated by an actuator (13) which is controlled by a pressure detector (9) in a cylinder. It is controlled to maintain the pressure at the end of compression constant at all engine loads.

Title: Electrical energy converter using solid state switching - includes fast acting regulator which assists harmonic suppression and has two stages of control
Inventor: GANSZKY KAROLY
IPC: H02M7/00
Filed: 1979-04-27
Abstract: The modified regulator is used for an energy converter, e.g., DC to DC or DC to AC, employing semiconductor switching elements. It has two stages of control. The basic timing signal is compared with converter output voltage, and then with a quantity directly proportional to output current. The resultant is used to control the gate pulses to the converter. The circuit ensures close copying of the basic timing signal by the converter. A frequency limit may be applied to the gate pulse rate. The regulator is intended to reduce harmonics in the output.

Title: Brick wall prefabrication equipment - has transfer mechanisms inserting and removing frames from jig to knock=out point
Inventor: SCHACH ALFRED DR
IPC: E04C2/04
Filed: 1979-05-04
Abstract: The equipment prefabricates large brick walls, having a travel track for a crab with hoist winch delivering an empty frame with inserted pallet, and transporting a full one to the knockout point. A jig lowers the frame in stages below the floor, and a transfer mechanism delivers a row of bricks, previously coated with mortar, into the frame. A transfer mechanism receives the empty frame from the crab and inserts it in the jig, which after insertion of the rows of bricks is lowered to bring the frame top edge below the floor. A second transfer mechanism then receives the fll frame below floor level and transports it sideways clear of the jig via rails on the cover of the trench to a second working position, where it is engaged by the empty hoist and lifted and lowered to allow any additional work to be carried out, after which the complete wall section is set down to be carried out, after which the complete wall section is set down at the knockout point.

Title: Suction-bell for pneumatic retrieval of broken yarn - has flexible shield plate attached to lower lip
Inventor: IGEL WOLFGANG DIPL ING
IPC: B65H67/08
Filed: 1980-04-03
Abstract: In a pneumatic device for retrieving a broken yarn end from a spinning package comprising an upwardly-directed air-jet which projects the ends into a suction bell over the top end of the spindle, between the spindle and the mouth of the suction bell is a shield-plate which lies in a plane perpendicular to the path of the air-stream to direct the air, and the yarn, into the mouth of the bell. The shield consists of a U-shaped plate of flexible material, pref. rubber, which may be affixed to the lower end of the suction bell. The shield prevents the yarn end from missing the bell, or snagging on the edge owing to turbulences in the air-jet. It whields the yarn emerging from the delivery-rollers from the air-current avoiding any disturbance which could disrupt the automatic piecening operation.

Title: Electrodes for electro-medical kinesis - uses five-pointed star shape allowing interdigitating
Inventor: SCHERER ERICH
IPC: A61N1/16
Filed: 1980-08-23
Abstract: The electrode for use in electromedical kinesis is designed for improved efficiency in certain applications compared to conventional arrangements. It is made of conventional wire in the form of a net or grid, and is made in the shape of a five-pointed star. This makes it possible for regions of adjacent electrodes to interlace and increase their effect. The electrode is embedded in insulating material with one side completely covered and the other fully exposed and with a central electrical connector. The design enables two, three or four identical electrodes to be used adjacent to each other. Two electrodes results in increased efficiency, whereas the use of two four-pointed star shaped electrodes results in only the same effect as the use of rectangular electrodes.
