Patent DE-2640821-A1 (DE)
Inventor: SATO YUKIO
IPC: B23Q39/02
Filed: 1976-09-10
Abstract: The object is to make it possible for the reference position between the cutting edge of a tool and a workpiece to be adjusted in a simple manner without the tool having to be displaced in the tool holder. To this end, there is a cam (42) which can be displaced in an angular manner about the tool axis. A plurality of connecting devices (23) are arranged between each tool holder (17) and cam (42) and normally separate the tool holders from the cam and can be operatively connected to it, so that the tool holders (17), which are driven by a hydraulic cylinder unit (35), can be moved for profile control in conformity with the cam (42). There are setting means (30) between the tool holders (17) and the connecting devices (23) so that an adjustment of the reference position of the tool holder (17) can be carried out. <IMAGE>

Title: Buoyant adjustable level swimming pool wall edge - floats upwards when housing recess is flooded and sinks when water falls
Inventor: SCHUSTER SIEGFRIED PROF DR ING
IPC: E04H4/14
Filed: 1976-09-13
Abstract: The vertically movable pool walling (3) is provided so that the water level can be varied if required, or so that waves can be generated at times without overflowing the edges. In the rest position it occupies a matching recess (1) and when this is flooded it flooded it floats upwards until it reaches stop positions where sealing and stability are effected by excess buoyancy. When water is let out, it returns to the rest position. Its buoyancy unit can be a hollow caisson (4), open downwards, floating in the flooded recess when air is released from bottom or recess, and sinking again when air is removed. The recess can serve also as overflow channel, with cover grating (9) lying on the movable pool walling. No reserve pool or pump is needed, nor mechanically or hydraulically activated flaps which are difficult to seal.

Title: Window case and frame with plastic sheath - have fittings joined to internal core with plastic sheath protecting against damp
Inventor: MERGLER WALTER
IPC: E06B3/30
Filed: 1977-01-20

Title: Motor vehicle heating system - has heat exchanger in exhaust pipe between manifold and silencer and thermostat controlling radiator by=pass flow
Inventor: THAUFELDER ALFRED
IPC: B60H1/02

Title: Tempering moving glass sheets - passing them through three air stream zones at different impingement angles
Inventor: SHIELDS GEORGE BENJAMIN
IPC: C03B27/048
Filed: 1977-07-20
Abstract: In tempering heated glass sheets by passing them between streams of cooling gas directed at the opposite faces of the sheets, the streams in the first zone are directed at a relatively large oblique angle to the plane normal to the major surfaces of the sheets, then at relatively small angle in a second zone, and finally the streams are directed normal to the sheet major surfaces in the third zone. The process produces tempered glass with high stress values, uniform cooling and good optical properties with min. development of lines.
