Patent DE-3067317-D1 (DE)
Title: Anti-kickback power tool control
Inventor: SAAR DAVID ALAN
IPC: F16P3/00
Filed: 1980-04-25
Granted: 1984-05-10
Abstract: An impending kickback condition is the operation of a power tool or machine tool system is sensed and used to control or eliminate the kickback. The ability to sense an impending kickback condition can be used in all categories of power driven tools. The change in force applied to the power driven tool or other implement is monitored by measuring the rate of change of speed of the tool or implement, and if the speed is decreasing, the rate of change of speed is compared with a threshold value which may be either preset or variable. If this threshold value is exceeded, an output control signal is generated which inhibits the coupling of power to the tool or other implement and/or applies a brake to stop the tool or implement. In order for power to once again be coupled from the motive power source to the shaft, the start switch must be opened and then reclosed or some other signal provided by the operator or another predetermined condition must be met.

Title: Process for the production of methacrylic acid from isobutyraldehyde
Inventor: BROCKHAUS RUDOLF DR
IPC: C07C45/58
Filed: 1982-08-24
Granted: 1984-11-29
Abstract: To produce methacrylic acid, firstly, isobutyraldehyde is acetalized. The resultant acetal is cleaved into the isobutenyl ether and alcohol. The isobutenyl ether is oxidized with molecular oxygen or an oxygen-containing gaseous mixture in the presence of an alkaline solution at temperatures of 30 DEG -70 DEG  C. to obtain the epoxide. This epoxide is hydrolyzed to the  alpha -hydroxyisobutyraldehyde. The latter is then oxidized with concentrated or fuming nitric acid at temperatures of 20 DEG -110 DEG  C. to produce  alpha -hydroxyisobutyric acid, and methacrylic acid is obtained therefrom by splitting off water.

Title: Device for switching an electrical connection in accordance with current and/or temperature
Inventor: HOFSASS PETER
IPC: H01H1/18
Filed: 1983-09-01
Granted: 1988-06-01
Abstract: For stopping drift or other undesired changes in the response temperatures of a thermal switch using a bimetallic element for driving a moving contact, the design is such that the moving contact and a counter-contact are supported on a common insulating supporting part and the counter-contact is elastically and yieldingly fixed on the supporting part. The lengths of the bimetallic element and of the a strip supporting the counter-contact that may be moved are different to each other so that the two contacts will make contact at different points thereon and with a rubbing effect for clearing oxide and other undesired coatings forming on the said contacts. For producing such a thermal switch with multiple functions, for example the functions of a temperature automatic controller and a thermal protective device, the counter-contact, that is placed so that it may give way elastically, is acted upon by a further bimetallic element.
