Patent DE-2018177-A1 (DE)
Title: Dough divider with stepping belt
Inventor: REUTER KLAUS
IPC: A21C7/04
Filed: 1970-04-16
Abstract: Drive, controls and power equipment for the kneader system are all housed in the lower part of the machine where a drive shaft carries cams for actuating the swivel levers and control levers, and for raising the lowering this bottom machine part, together with the kneaders which are thus contacted with or retracted up from the dough on the stepping belt above. The swivel levers link the spur wheels driven by a motor mounted in the lower part housing to the tool arm above, and the swivel levers are gradually moved out from a position coaxial to the spur wheel shafts by means of control levers which are actuated by the main drive shaft cams as kneading commences. Space is saved, transmission reliable and the outwards increasing radius of kneading attack maintained in a compact machine.

Patent DE-2025271-A1 (DE)
Title: Calcined alumina cooler - with disintegrator contg air jets - to blow material against concave plate
IPC: B02C19/06
Filed: 1970-05-23
Abstract: Cooling chamber for calcined granular material such as Al2O3 incorporates a disintegrating device consisting of one or several jets directed into the material to be broken up working on the principle of energy.

This is connected into a circuit including a second rotary potentiometer forming a specified value source. Other potentiometers control the top limits of the stroke of the press and its mode of operation (single or double handed) and a deviation amplifier linked to inching buttons permits the adjustment of the specified value to the actual value down to zero, for completely automatic and accurate setting.
Patent DE-2326723-A1 (DE)
Title: Multiple rolling mill stand assembly - with unified differential spee control system
Inventor: KOUMP VALENTIN
IPC: B21B37/00
Filed: 1973-05-25
Abstract: The assembly comprises a number of individual stands in series with two rolls each and separate drives for each stand. The control system for these fixes the roll speeds in the stands such as to set up tensile stresses between successive roll stands causing elongation and thickness reduction of the workpiece material. Speed control is based continuous thickness and width measurements. The system allows the use of very simply designed rolling mill stands with fixed gaps, which stands can be changed over very quickly and easily.

The parabolic curved achieves a gentle slowing down of the article before it strikes the stop-block on the arm. The photo-electric cell is placed so that at first it registers the arrival of the article at the removal position and when in the exact position will activate the removal mechanism, which typically is hydraulic cylinder.
Patent DE-2346299-A1 (DE)
Title: Injection jet pump for central heating - has throughput regulated by means of axially movable disc
Inventor: BAELZ JUERGEN DIPL ING
IPC: F04F5/48
Filed: 1973-09-14
Abstract: The pump has a housing with inlets for the liquid being pumped and a pipe connection for the driving fluid. The driving fluid leaves the pipe through side holes and flows round the outside of a cone through the pump throat into the discharge diffuser. An axially movable cone surrounding the fixed cone varies the flow of driving fluid by adjusting the annular space round the solid cone. A disc with a central hole surrounding the outer cone is carried on a bellows and is axially adjustable. Its movement varies the space between itself and the outer cone through which the pumped fluid flows thus varying the throughput.

Patent DE-2361071-A1 (DE)
Title: Adhering friction lining to support shoe - comprising transmitting heat to adhesive directly through lining or support
IPC: F16D69/04
Filed: 1973-12-07

Apparatus for carrying out the method has a device, e.g. a hydraulic actuator, for pressing the lining, as assembled on a brake shoe, against a heater body having a concave surface fitting the radius of the lining. Heat is applied to the body by passing heated oil through. The heat penetrates the lining so quickly that the adhesive between the shoe and the lining, e.g. phenolic resin, is brought to plasticizing temperature (200-500 deg.C), and the adhering process completed, in 1-2 minutes compared to 30-40 minutes in known processes.

The longitudinal movement of the press piston is transmitted to the movable parts of the mast via a lifting cable or similar, and deflector rollers. The cylinder of the lifting press extends to the rear end of the fork lift truck. The cable runs in a block-and-tackle fashion between one set of rollers fitted to the piston head and one set stationary on the truck.
Patent DE-2426769-A1 (DE)
Title: Digital signals transmission method - esp. suitable for difference signals with weighted protection against errors in code elements
Inventor: LIPPMANN REINER DIPL ING
IPC: H04L1/00
Filed: 1974-05-31
Abstract: Error protection is realised in the different bit planes by addition of artificial redundancy. Code words are so allocated to signal values, that significant signal value changes caused by interferences are produced in selected bit planes by distortion of code elements. Only code elements in the selected bit plane are transmitted with protection. Significant changes of signal values are produced by distortion of code elements in a bit plane, and only code elements of this plane are transmitted with protection. The coding is so carried out, that when an error in the protected bit plane appears, at least two-step distortion of signal values takes place.
Patent DE-2437349-A1 (DE)
Title: Wax removal from mould of lost wax casting machine - by irradiation after introduction of matl. with high loss factor
IPC: B22C9/04
Filed: 1974-08-02
Abstract: The wax is molten and removed from the precision mould of a lost wax casting machine by introducing into the structure of the mould a material with a high loss factor (over 1, 0) in the frequency range from 300 to 30,000 MNz (900-2500 MHz). The preferred material is graphite or carbon in the form of a coating. The mould is then irradiated by microwaves of this range until the wax has become liquefied. This is less expensive than using solvents and releases no toxic fumes. It is easier to operate and to include in a flow line production than wet steam heating in an autoclave. The wax is molten on the surface before thermal elongation can crack the ceramic shell. The process is automatic and continuous.

Patent DE-2446284-A1 (DE)
Title: Multi-purpose air compressor - uses tyre to act as air buffer for smooth supply to spray gun
Inventor: EHS EUGEN
IPC: B60R99/00
Filed: 1974-09-27
Abstract: The compressor is driven by an electric motor supplied from the car battery. The pulsating air discharge from the compressor is suitable for inflating tyres, dinghies or similar items, where the pulsation does not affect the ultimate use. It is unsuitable for operating a spray gun. The present design proposes to connect the discharge end of the compressor to a three-way distributor, with connections to the compressor, to a tyre, for instance the spare tyre of a car, and a connection to a spray gun. The air content of the tyre acts as a pressure vessel, resulting in the required steady flow of compressed air without pulsation.

Title: Continuous automatic casting machinery for non-ferros metals - in which ingots are cast, cooled, stacked, weighed and made into bundles
Inventor: KIKKAWA TAKAHIRO
IPC: B22D5/04
Filed: 1974-10-09
Abstract: In the continuous, automatic casting of non-ferrous metal in chilled moulds to mfr. ingots or bars which are clamped and bundled together in a stack, a prescribed vol. of melt is fed from a constant vol. casting device into a mould on a chain conveyor carrying the mould via a stripper device which removes slag and scrum, into a cooling zone, and the cast bar is then ejected onto a second conveyor which forms a vertical stack using an alternating arrangement of the bars in each layer, i.e. to form a stable stack; the stack is conveyed to a weigher followed by clamping and bundling. Used for the mass prodn. of high quality ingots of zinc or other non-ferrous metals.
