Title: Surface heat treating of aluminium@ parts using energy beam -  to produce spot-like or oscillating line exposure over short time period with process repeated several times
Inventor: PAASCH RUDOLF
IPC: C22F3/00
Filed: 1990-09-07
Abstract: Surface heat treating of Al parts of a combustion engine is carried out using an electron or laser beam which rapidly melts the surface over a short time period and after resolidification repeats the process several times. - The short time period for heating is 50-300 msec. and is repeated 3-7 times with decreasing energy beam power.

Title: Ergonomically designed clearing saw - has circular-saw blade on end of tubular handle and uses drive moment to counteract side-kicking of handle
Inventor: ELLSAESSER DIETRICH GERHARD
IPC: A01D34/90
Filed: 1991-05-22
Abstract: An ergonomically designed clearing saw for cleaning and releasing operations in young plantations has a circular-saw blade on the end of the tubular handle. The side-kicking tendency of the handle cuased by the saw blade is countered by the drive moment of the motor in such a way that a drive unit, arranged so that it can rotate about the drive axis of the motor, can swing out laterally when a counter-moment is applied. ADVANTAGE - Reduces the tendency of the implement to kick back or to the side, thus enabling ergonomically more favourable operation.
