Title: Temp.-resistant connector wire - consists of a highly conductive core and a platinum@-rich mantle into which gold@ has been diffused to allow easier connection
Inventor: WIENAND KARLHEINZ DR
IPC: H01B1/02
Filed: 1991-08-06
Abstract: The electrical conductor wire has a max. dia. of 1.2 mm with a core (2) of pref. Ni or an alloy of Pt with 1-4 wt.% W, and a mantle (1) pref. up to 80 micron thickness, which is coated with a Au layer (3) of 0.05-1 micron thickness, pref. 0.2-0.5 micron. The Au content of the mantle pref. decreases in the direction of the core. The coefft. of thermal expansion (CTE) of the core pref. matches that of the mantle. A mfg. process is also claimed. Into a tube, consisting of Pt, a rod consisting of core material is placed. The workpiece is then drawn into a wire. After formation of the wire a thin Au layer is deposited, pref. 0.05-1 micron thick, pref. by electro-plating, sputtering or evaporation. The wire is then annealed until Au has diffused to the interface between mantle and core. USE/ADVANTAGE - The wire is used for the connection to a measurement resistance, especially a resistance layer. The structure allows easy connection using any of the following techniques : soft-soldering, hard soldering or laser-welding. The wire is easily wetted and does not cause solder contamination with Au, preventing joint brittleness as formed or after high temp. use.

Patent DE-4130118-A1 (DE)
Inventor: MAROSZEK HERIBERT
IPC: D06B1/14
Filed: 1991-09-11
Abstract: Devices are known for coating webs of material (3), in particular paper or cardboard webs, that have an applicator (4) and dosing system (12) mounted on swivelling arms (7, 13) in order to swivel the applicator (4) and dosing system (12) from a maintenance position to a working position at a mating roll (2). According to the invention, the swivelling mechanism of the applicator (4) and/or dosing system (12) has, besides the cylinder unit (9, 18) for swivelling from the maintenance position to the working position, a hydraulic piston-cylinder unit (10, 20) that presses the swivelling arms (7, 13) out of the working position into an intermediate position. The applicator (4) and/or dosing system (12) can thus be very quickly and accurately swivelled into or out of the working position at the mating roll (2).
Patent DE-4133264-A1 (DE)
Title: Conveyor system reforming flow of containers -  has uniform acceleration of incoming containers through rising speed of conveyor rollers
Inventor: BRUDER HARALD R
IPC: B65G47/68
Filed: 1991-10-08
Abstract: When reforming multi-row wide container flows into a single-row container flow (2) inside a transport device the wide container flow coming from the supply transporter first becomes quicker over an acceleration section (3) by means of a drive-side translation of the conveyor rollers towards the conveyor direction and thus each following roller in the conveyor direction rotates 3 to 6% faster than the previous roller whereby beneath one container there are at least three conveyor rollers turning at different speeds resulting in a uniform acceleration on the incoming containers whilst the distance between the incoming containers has increased until the container has reformed in a single-row stream owing to the forces acting on the container flow across the conveyor direction. The containers are interpositioned through a single-sided guide railing and an additional inclined position of less than 8 deg. of the device in the direction of the railing. A following deceleration in the conveyor roller speed acting in an inverse ratio can cause the single row of containers to close up tight towards the discharge point. USE/ADVANTAGE - The changes in speed take place only in the conveyor direction.

Title: Method to reduce solid deposits in hydroelectric power station - uses swirl plate, to generate backflow on rake, to churn-up deposits, and flush through small solids
IPC: E02B8/02
Filed: 1991-10-30
Abstract: The method reduces the collection of deposits on cleaning rakes in hydroelectric plant, etc. A turbulent backflow is generated on the rake, to churn-up any collected deposits. Any small solids in the deposits are flushed through the rake. The backflow is generated in a limited area only, so that it charges only part of the rake, eg along its length. The process is carried out by a swirl plate (10), which is located in the current in front of the rake (1). The plate is movable parallel to the rake tines (3). ADVANTAGE - Small solids are not removed from water current.

Title: Lock for road vehicle safety belt with holder - incorporates U=shaped lock component with tooth at front end engaging through aperture in insertable tongue
Inventor: TEDER LEONID
IPC: A44B11/00
Filed: 1992-03-05
Abstract: A holder part is formed as a tongue (13) with a loop for a belt branch and with a flat insert section (12), which at its end has a pref. rectangular opening (15). An accommodation part comprises a holder (1) fitted in a protective housing (53). In the holder, a U-shaped locking component is pivotably located, which incorporates a locking tooth (11), working in conjunction with a pref. rectangular stop aperture (20) in the floor of the holder (1). The force of a sprung thruster (26) for the tongue, acting on the stop surface of the locking tooth (11) tries to pivot the locking component (2) from its locked to the freed position. A sprung and displaceable stop element (18) blocks the locking component in its locked position, and an operating key opens the lock by moving the stop element (18). In the front part of the holder (1) two symmetrical stop formations (23) are bent at right-angles into the holder, and form additional supports for the face part (10) of the locking component (2) during extreme loads on the lock. ADVANTAGE - To overcome the disadvantage with known vehicle seat belts whereby the distance between the stop component and the stop surface of the locking tooth is not suited to a bending strain.
