Patent DE-2011139-A1 (DE)
Title: Spaetzle forming machine
IPC: A21C11/16
Filed: 1970-03-10
Abstract: Dough spaetzle are made by passing the dough under pressure through holes in a plate at the bottom of a piston or screw press. As the pressure increases, the holes expand to the required size thus permitting the dough to pass through and be shaped. When pressure is cut off, the holes spring back and cut off the dough in so doing. The outlet holes can be funnel shaped with counter-sunk end areas to seat the splay-out nozzles fitted as dough ejectors. The nozzles can be at a slant to the surface of the plate and are split from the tip over half their length for better splay and return movement. The plate can be integrated with the press cylinder base. They compare favourably with hand made in terms of taste, aspect and consistency, and with cheap equipment the time required is appreciably shortened as compared with hand manufacture.

Title: Shed formation for warps in looms - by thyristor controlled current coils in magnetic field
Inventor: DOEHLER PETER DIPL KFM
IPC: D03C13/00
Filed: 1973-04-03
Abstract: Groups of warp threads in a weaving loom are linked to flat current coils which are located in the magnetic field of powerful magnets. When a d.c. voltage is applied to selected coils, they are moved and raise the warp threads connected to them to form an open shed. Each current coil is fed through a thyristor, the gate of which is connected to the output of an AND-circuit. The inputs of the latter consist of a command pulse to control the warp thread movement and a timing pulse synchronised with the voltage of the a.c. supply. This makes it possible to feed the current coils directly from the mains supply. A combination of the rectification for the current coils with the selective coil control saves additional instrumentation. This simplifies and cheapens the equipment.

Title: Hydraulic clearance compensator for I.C. engine valves - has a cylinder and a piston arrangement which is not drained completely when engine is stationary
Inventor: KUECHEN RICHARD
IPC: F01L1/24
Filed: 1973-08-28
Abstract: The hydraulic clearance compensating unit for the engine valve operates with the lubricating oil circulating within the engine, and is fitted on the engine block to provide support for the connecting element between the cam shaft and the valve stem. The cylinder and piston arrangement is designed in such a manner that the oil is not drained from the cylinder and piston assembly when the engine is stopped. This aspect is very important because air may be otherwise drawn into the compensator when the engine is restarted. The arrangement ensures that on restarting there is always sufficient oil within the system for correct operation. The piston within the cylinder has a cavity which is connected by the non-return valve to the cylinder chamber. The oil can flow only from the piston cavity into the cylinder. Oil is supplied from the engine oil circulation into the system. The piston cavity contains a cylindrical funnel shaped element which acts as a seal for radial bores in the piston wall.
