Title: Warp kknitting machine guide rod blocking mechanism
Inventor: BAU TOSHIO
IPC: D04B27/26
Filed: 1969-07-17
Abstract: Guide rods are held parallel to each other by a guide rod swing frame and can each be moved to and from in longitudinal direction. Buffer devices are connected to the guide rods, the buffer devices being coordinated with a mechanism supplying a blocking action to them. Parts of the mechanism supplying the blocking action are spaced at a distance from each other which is greater than the distance between two adjacent guide rods. Fixed bodies are arranged to slide on a frame in the longitudinal direction of these buffer devices and the parts of the mechanism supplying a blocking action. The space between neighbouring parts of the fixed bodies at the point where they are connected to the buffer devices is smaller than the space between the adjacent parts of the fixed bodies which are turned towards the parts of the mechanism supplying a blocking action, so that the buffer devices are aligned approx. parallel to the guide rods. Advantage is no reduction in the number of guide rods, but at the same time the possibility of a large variation in knitted products, fabrics and patterns.

Title: Cooling rolls in flattening lead solder - by spraying with alcohol
Inventor: DAVIS DANIEL BRYAN
IPC: B21B1/16

Title: Grinding machine with oscillating grinding wheel - is driven by an actuator via a rack and pinion
Inventor: REDKO SERGEJ GEORGIEWITSCH
IPC: B24B19/06
Filed: 1973-12-05
Abstract: The workpiece to be ground rotates in one direction, while the grinding wheel oscillates about its axis over an angle of up to plus and minus 180 deg. The grinding wheel reaches a circumferential speed during its oscillation of up to 100 m/min. relative to the workpiece. The speed selected depends on the material of the workpiece. The angle of oscillation of the grinding wheel is gradually reduced to zero during the machining of the workpiece, while its circumferential speed is maintained. A kinematic coupling connects the grinding wheel shaft to a drive shaft on which a spur gear is mounted. A rack engages with this spur-gear. The rack is an extension of the piston rod of a pneumatic actuator which imparts the oscillating movement to the rack.

Title: Signal content scrambling method - consecutive time sections or representation signals are separately stored
Inventor: BITZER WOLFGANG DIPL ING
IPC: H04K1/04
Filed: 1974-06-01
Abstract: The scrambling method is designed for signals with a limited band width. Time consecutive sections of the signal voltage, or signals representing it are separately stored, and then read out in parallel at a lower speed during a period equal to their duration. Signals read out from different stores are modulated on different frequency carriers and transmitted by the frequency multiplex method. The processes are reversed at the receiving end and the original sections are read out at the correct speed and sequence. A further scrambling can be achieved by staggering and irregularly changing the order of the stores.
