Title: Hide fleshing system - with better machine utilisation by turning hides after half-finishing operation
Inventor: GABELMANN ERICH
IPC: C14B17/06
Filed: 1977-03-17
Abstract: A fleshing system for hides and skins is based on treating them on one-half first. The semi-finished articles are then returned to the loading station where they are attached to the over head feeding monorail alternating with untreated articles. After the second half has been fleshed a conveyor draws the finished product to a pallet. This shifts the time required for turning a hide to be combined with the return time so that the utilisation factor of the fleshing machine itself is much increased.

Title: Automatic machining process using multiple cutting heads - has tools rotated in opposing directions with torques imposed by cutting assessed by microprocessor
Inventor: LINDEMANN HANS
IPC: B23B1/00
Filed: 1977-07-15
Abstract: In manufacturing components from bar, several operations may be carried out simultaneously at different regions along the length of the bar. This is arranged by feeding the bar past a number of different work stations arranged in sequence. With this method of manufacture there is a danger that the bar may be damaged by the excessive torque imposed on it. This danger can be avoided by arranging that some of the cutting tools rotate in one direction whilst the rest rotate in the opposite direction. A micro-processor is used to calculate the torque imposed by each operation and choose the direction for each operation so that the resultant torque is a minimum.
