Patent DE-2236161-A1 (DE)
Title: Armature stampings - produced from cold-rolled sheet metal rounds with a notching press
Inventor: WINKLER JOSEF
IPC: B21D28/22
Filed: 1972-07-22
Abstract: Armature stampings for electrical machines are produced by notching cold-rolled sheet metal rounds by initially providing them with guide holes or grooves arranged in a specific position w.r.t. the direction of sheet metal rolling. A carrier plate engages the guide holes and rotates the round by one notch division prior to punching out the first notch. This is followed by marking out a predetermined position w.r.t. the notch, and then punching the remaining notches. Finally, the stampings are assembled together so that the markings on the stampings are superimposed.

Patent DE-2408469-A1 (DE)
Title: Fuel injection pump for diesel engine - reduces noise due to pressure wave in fuel delivery pipe
Inventor: AUGUSTIN ULRICH DIPL ING
IPC: F02M59/02
Filed: 1974-02-22
Abstract: The fuel injection nozzle is supplied with fuel through the pipe from the pump. Fuel is drawn through the port and upward movement of the piston closes off the port and then forces fuel through the non-return valve. Before fuel can be delivered the pressure in the pipe must be sufficient to overcome the force of the spring on the needle valve in the injection nozzle. The pressure is transmitted by a pressure wave which oscillates between pump and nozzle causing the characteristic 'sawing' noise of a Diesel engine. This noise can be eliminted by increasing the head volume space of the pump.
Patent DE-2413506-A1 (DE)
Title: Loose fibres drying system - has pulsed delivery of hot air into base of drying vessel to create turbulent effect
Inventor: KAUPP JOSEF ING
IPC: F26B15/04
Filed: 1974-03-20
Abstract: Designed for drying synthetic cellulose fibres, a series vertical holding vessels with a trapezoid cross-section are grouped round a shaft, to be brought into the drying position where hot air is passed in from below, with a flow control valve to give a pulsed air delivery of 1-15 pulses/min. This creates turbulence among the loose fibres by the air flow, so that the fibres are loosened and whirled round to be exposed to the hot air, to give an even and consistent drying effect, occupying less space and with lower energy consumption than conventional equipments.
Patent DE-2427611-A1 (DE)
Title: Plastics articles heated by infra-red radiators and reflectors - along two parallel paths with radiators between
Inventor: LEMKE HEINRICH
IPC: B29C49/68
Filed: 1974-06-07
Abstract: The parent patent describes a device for heating plastics articles, esp. for further treatment, which consists of an infra-red radiator and a curved reflecting surface. In the patent of addn., the infra-red radiators are mounted between two conveying paths for work-pieces, and reflecting surfaces are arranged symmetrically about the central plane of the radiators, thus reflecting the heat back onto the workpieces. In the parent patent, one side of each workpiece received radiation from a reflector only, while the other side received it both from a reflector and from the heat source, resulting in some inbalance. In the new arrangement, this is largely corrected.
