Title: Resistance welding steel bars to mfr. grids - using sensors to measure electrode pressure and displacement and the welding current
Inventor: DEFOURNY JACQUES
IPC: B23K11/25
Filed: 1978-06-09
Abstract: This is an addn. to 839697, which described appts. for controlling electrode pressure and displacement, and electrical energy, in the welding of steel prods. In the present invention, the sensors consists of (a) a toroid placed on the bridges connecting the upper electrodes in pairs and measuring electrical energy; (b) a load cell is located above a compression spring in each electrode holder and used to measure the pressure exerted on two upper and two lower electrodes; (c) two gauges are formed by a pair of dummy electrodes through which no welding current flows, the movement of the gauges indicating the displacement of the actual welding electrodes. The prods. being welded are pred. steel bars, e.g. forming a grid or trellis, where sensors(c)measures the penetration of the bars into each other. Load cell(b) is pref. located in a plug used to clamp each spring, esp. a plug with a graduated scale used to calibrate the spring. Improvements to the main patent so the sensors do not interfere with the welding zone.
Patent DE-2825441-A1 (DE)
Title: Flat pressure filter for multicomponent filter element - having circular upper cover with projecting lid inside outer radius with curved wedge profile to hold O=ring
Inventor: HEIN WOLFGANG DR
IPC: B01D29/05
Filed: 1978-06-09
Abstract: Pressure filter has a flat surface with upper and lower sections. These are combined by a flange using O ring type seals to mount the filter medium. The upper section has a projecting lip set back from its rim, the outer edge of which has a concave wedge profile. This forms a groove onto which the upper O ring seal presses. The max. radial spacing between the concave surface and the cylindrical inner wall of the projecting lip of the lower section is equal to the dia. of the O ring. The axial height of the concave surface is slightly larger than the radius of the O ring, and slightly smaller than its cross-section when at its max. distortion when the unit is clamped together. Used for filter liquids under pressure. Arrangement allows the use of thicker and multiple layer filter elements for pressure of >=10 bar, and is easy to handle and cheap to mfr.
Patent DE-2836352-A1 (DE)
Inventor: PETER JULIUS DR
IPC: B60C15/00
Filed: 1978-08-19
Abstract: A pneumatic vehicle tyre is disclosed having two carcase plies (5, 6) in the side wall (7) of the tyre and a rubber layer (11) of low internal friction located between the pies. One carcase ply (6) is anchored in the tyre beads (9) by being looped around the bead cores (10) and extends to the associated tyre shoulder (8). The second carcase ply (5) extends from one tyre bead to the other, but is not anchored by its edges to the bead cores (10). The ply (5) thus terminates closely above the bead cores (10). <IMAGE>

Title: Travelling wave loom with weft end grippers - rotating with beat up shaft to grip weft adjacent shed
Inventor: BORODIN VALERIAN A
IPC: D03D47/26
Filed: 1979-02-05

Patent DE-2930312-A1 (DE)
Title: Screen-type centrifuge with washing fluid supply - at reduced speed providing thicker and less damaging film
Inventor: HULTSCH GUENTHER
IPC: B04B11/06
Filed: 1979-07-26
Abstract: A screen-type centrifuge has an inner sieve with cylindrical walls and divided into pockets, and a frusto-conical upwardly widening outer sieve. Between these is a concentric drum-like cap which is supplied at the top with fluid for washing solid material adhering to the inner sieve wall. At high rotary speeds the washing fluid would form a thin and fast-flowing film and thus provide only ineffective washing. The cap is rotated at a lower speed than the inner and outer sieves, which may themselves rotate at equal or different speeds, and so produces a thicker and more effective film of fluid. The cap is freely rotatable, esp. on a fixed vertical filler pipe. The centrifuge is esp. for prodn. such as sugar which have readily damaged crystals. The rotary parts are readily replaceable and the drive is simple.

Title: Cue mark inserter for editing video tape - has pulse generator and mixer for inserting bar cue marks
Inventor: WELLHAUSEN HANS
IPC: G11B27/34
Filed: 1979-09-26
Abstract: The mark appears as a vertical bar across the picture area at a predetermined time before a cue is to be applied. The bar may be black, white or coloured. A trigger pulse is generated and mixed with the picture signal to produce the cue or sync. mark. A picture and sound replay unit (1) feeds its picture signal output (2) into the sync mark mixer equipment (3) before it is displayed on a monitor (5). A process control unit (7) may be used for storage of the information relating to sync/cue mark application. A trigger pulse (6) is output from the process control (7) or replay unit (1). A pulse length is selected for the required purpose and transmitted through the sync mark scan generator (9), when triggered by the incoming pulse (6), into the mixer stage (4) for mixing with the picture signal. The mixer equipment (3) also contains separator stages (11), coupled through to the mixer (4) from sync recognition stages (12), for the removal of sync/cue marks.

Title: Diesel engine injection nozzle - has swirl chamber with auxiliary spray hole built into needle
Inventor: FUESSNER PAUL DIPL ING
IPC: F02M61/18
Filed: 1979-10-13
Abstract: The diesel engine injection nozzle has a needle (2) seating in a conical seat (4). Fuel is supplied through passage (6) into pressure chamber (5). The needle contains a swirl chamber (7) which leads to an auxiliary spray orifice (8). The swirl chamber (7) is supplied by tangential feed holes (9). At low engine speeds most of the fuel is supplied through orifice (8). As the amount of fuel increases at higher engine speeds, the needle lifts further and fuel is sprayed through the annular gap (11) in the normal manner. Good atomisation is therefore achieved under all running conditions.
