Title: Overload safeguard for shear forces - has ball engaging with hardened bush mounted in mating part
Inventor: BRAGGINS GEORGE RODERICK
IPC: F16D43/206
Filed: 1974-11-12
Abstract: The ball (35) is forced against the hole (34) in the bush by a grub screw (38) which is mounted in a small plunger (28). The plunger with grub screw is spring loaded against the ball by means of a stack of Belleville washers (25, 26) which are mounted round the outside of the plunger. The Belleville washers press against a washer conical face which lies against a row of balls (27) which are also placed round the circumference of the plunger at a place where the diameter of the plunger is reduced (29). If the locking ball in the bush is forced against the plunger when the two faces move relative to one another, the balls round the plunger will ride up the part with larger diameter and force the conical and Belleville washers down.

Title: Milling tool for cutting pipes - has one milling tooth only in engagement with workpiece at one time
Inventor: MUELLER HARALD ING GRAD
IPC: B23C1/00
Filed: 1974-12-05
Abstract: The workpiece is subjected at the point of separation to a radially advancing tool action in its circumferential direction. During this action only one tooth of the milling tool is in engagement with the workpiece. The ratio between tooth advance feed and depth of cut is greater than 1, the depth of cut being less than 1 mm and the speed of cut greater than 600m/min. The innate kinetic energy required for the material removal during the cutting operation is self-compensating until the next engagement. The distance between teeth on a multiple toothed tool is so chosen that before a subsequent tool cuts the kinetic energy lost during the cutting operation of the previous tool is further recuperated in the tool.

Title: Moving and fixed tables for grouping of rough clay blanks - preventing blanks from moving during grouping
Inventor: ANSCHUETZ RUDOLF
IPC: F27D1/00
Filed: 1975-09-24
Abstract: Device for grouping rough clay blanks comprises a fixed table and a movable table which slides over the fixed table. Mounted above the movable table is a supporting bar which is adjusted automatically. In an example a row of blanks includes closely adjacent blanks of which the number depends on the blank size and stack width.
