Title: Stud welding zinc coated steel sheet to girders - using gas burner to remove coatings prior to welding
Inventor: MUESS HANS ING GRAD
IPC: B23K9/235
Filed: 1976-01-20
Abstract: Joint surfaces are pretreated before stud welding, esp. for the welding of studs onto both steel sheet and a carrier beam where the stud passes through the sheet which is coated with Zn, lacquer or other layer, or for making concrete anchors. A fuel gas and oxygen flame, or electric energy, is used to burn the Zn off the steel sheet or profiled sheet in the welding zone, and also to remove any coatings from the surface of the top boom or flange on the carrier beam to which the stud will be welded. The result is the removal of impurities which would impair the quality of the welds. A heat-conducting ring is pref. placed round the welding zone on the steel to confine the flame from a burner used to remove the Zn; in this way the Zn coating outside the welding zone is not damaged. Process uses an arc to burn a hole in the steel sheet and the stud is then welded on both the sheet and an underlying beam, e.g. in mfg. stressed ceilings in multi-story buildings, or in other constructional work using concrete.

Title: Black box speed recorder for motor vehicles - has endless magnetic tape loop recording pulses from speedometer drive
Inventor: WOBST JOSEF
IPC: G07C5/08
Filed: 1976-05-03
Abstract: The 'black-box' speed recorder for motor vehicles provides a continuously up-dated record of a vehicle's speed - the information being valuable evidence in the case of an accident. An additional electrical or mechanical unit is coupled to the normal tachometer drive to the vehicle speedometer. Using an impulse transmitter, the speed is recorded for a short period of time. A miniature tape recorder, fitted with an endless loop of tape receives and stores the audio pulses from the drive shaft of the speedometer. The information is therefore continuously erased and recorded depending on the length of the loop. In the case of an investigation, the data can be interpreted via a specially-designed playback unit.
Patent DE-2620627-A1 (DE)
Title: Dewatering filter cakes esp. on band filters - by applying mechanical pressure while blowing with gas
Inventor: HAVALDA PAUL
IPC: B01D33/00
Filed: 1976-05-10
Abstract: The water content of cake on (esp.) band filters to reduced by compressing it. The pressure gradient is through the cake to the filter. Mechanical pressure is applied over most or all of the cake surface. At the same time gas may be made to flow through the cake. Method is for reducing the water content in filtiations where the cake is the required product, esp. in pigment preparation. The mechanical pressure prevents cracking of the cake which limits the final water content in simple blowing. The cake may be blown with a dry gas which is air or CO2 and/or N2. The gas temperature is 10-50 degrees C. Before dewatering the cake is treated with liquid and made into a slurry and then washed. The mechanical pressure applied in dewatering is 1-12 bar (pref. 3-4 bar).

Title: Power-assisted reactor safety-valve with pneumatic cylinder - with small chamber volumes giving rapid response to air pressure
Inventor: SCHAAF KARL
IPC: F16K31/122
Filed: 1976-06-12
Abstract: A spring-loaded safety valve, esp. for nuclear reactors, has a controlled additional loading system comprising a pneumatic cylinder connected to the valve closure member and capable of being actuated towards either closure or opening. The supply to this pneumatic cylinder is through air valves actuated by pressure monitors connected to the fluid line in which the safety valve is mounted. The piston of this pneumatic cylinder is a stepped piston with only a slight inward step on its upper face. The cylinder carries a guide projection which extends sufficiently far down into the narrow annular gap between the step and the cylinder wall for the depth of the thus formed air chamber acting upon the piston to be equal only to the stroke of the valve closure member plus the necessary clearance. The base of the pneumatic cylinder is sufficiently near the bottom of the piston for the depth of the air chamber located between them (the air chamber providing the valve opening motion) to be equal only to the necessary min. clearance to enable the valve to operate correctly to the open position. The periods required for the build-up and decrease in the air pressure for either direction of the valve are considerably reduced, so that a rapid-opening and rapid-closing, power-assisted safety valve suitable for reactor purposes is obtd.

Patent DE-2706743-A1 (DE)
Title: Transmission control for DC traction vehicle - has electronic control for centrifugal clutch to isolate gearbox during speed change
Inventor: EMMANN SIEGFRIED ING GRAD
IPC: B60L11/18
Filed: 1977-02-17
Abstract: The DC traction control has a centrifugal clutch (5) between the motor and the gearbox (9) so that the motor torque is established before the drive is engaged. The clutch is linked to an electronic control so that it can also be used as a conventional clutch when changing gear ratio. To operate the gear change a clutch pedal is depressed. This drops the armature current to the motor, via a switching thyristor (3) so that the gear can be disengaged, on loss of drive torque. Before the new gear can be engaged, a further electronic control opens the clutch and provides a braking control to synchronise the gears.
Patent DE-2716413-A1 (DE)
Title: Hard metals prodn. by powder metallurgy - using mixt. contg. metals, carbon, and cpds. forming boride(s), nitride(s), and/or silicide(s)
Inventor: JESSEN JOERN J
IPC: C22C1/05
Filed: 1977-04-14
Abstract: Hard metals contg. metal carbides are made, starting from a powder mixt. contg. (a) metal powders; and (b) carbonaceous material; and opt. also (c) inorganic and/or organic cpds. The loose mixt. or a pressing made from the mixt., opt. with a binder(d), is heated, and then sintered and cooled to obtain a hard metal (2) contg. carbides and/or borides, nitrides and silicides in mixed crystals, and/or hard metal-oxides. The carbon required may be used as such, or be present in binder(b). When an organic binder is used, gradual and/or stepwise heating is pref. employed so gases formed by decompsn. of the binder can diffuse out of the mixt. without causing internal pressure. Decompsn. of any organic cpds. present pref. occurs below 800 degrees F. Mixt. may also contain catalysts, e.g. halogen salts, which promote the formation of carbides. Hard metals are suitable for all types of industrial use, e.g. tools drills, dies. The need for expensive metal carbide powders is obviated.
Patent DE-2720105-A1 (DE)
Title: High-efficiency blasting charge assembly - uses explosive charge encased in flexible water-filled jacket which assumes bore contour
Inventor: LEPPAK WILHELM
IPC: F42D1/20
Filed: 1977-05-05
Abstract: The explosive charge is surrounded totally or partly by a jacket filled with water, which due to its in compressibility transmits the entire blasting force to the material to be blasted. The jacket consists of a thin-walled plastics bag into which the explosive charge is placed and the bag filled with water. The water-filled charge bag assumes the same diameter and contour of the bore hole, so that physical contact is established. The direct contact of the non-compressible pressure wave transmitting bag with the blasting surface increases charge efficiency and the need for precision in boring.
