Patent DE-3913898-A1 (DE)
Title: Adjustable guard for portable power tools - has indent mechanism for angular adjustment and finger pressure actuated fastening to spindle nose
Inventor: GOECMEZ MUSA
IPC: B23Q11/08
Filed: 1989-04-27
Abstract: Known guards for portable power tools such as angle grinders do not have positive intermediate angular adjustment and can only be removed by the use of a screwdriver. To allow positive angular adjustment the collar (16') is provided for part of its circumference with serrations which engage with a spring loaded pawl. Finger pressure on the extended end (20") of the pawl disengages it and allows the guard to be turned from one indent position to another. The collar (16') is secured on the spindle nose (19) by engagement of the spring clip (21, 25) in the circumferential groove (22); finger pressure on the spring releases the guard. ADVANTAGE - Guard has locking intermediate angular positions and can be removed without the use of a hand tool.

Title: Program execution monitoring arrangement for microprocessor controller - uses two watch-dog timer stages, one of variable, one of fixed period
Inventor: KLEIN JOSEF
IPC: G06F11/00
Filed: 1989-04-27
Abstract: A timer is reset by pulses generated during correct program execution. If reset pulses are not produced the timer generates control information when a defined period has elapsed. The timing value of a first monitor stage (WD1) is selectable within a defined range according to the operating state of a controlled system. The reset pulse generated by this monitor initiates a subsequent, fixed period monitor stage (WD2) which interrupts operation of the controlled system if its time elapses. USE/ADVANTAGE - Monitoring program execution in stored program digital communications systems. Adaptable to different microprocessors and applications.

Patent DE-3929475-A1 (DE)
Inventor: WEGMANN URS DIPL ING
IPC: H01J37/147
Filed: 1989-09-05
Abstract: In order to utilize a magnet arrangement having a magnetic flux density field for beam guidance in the deflection of a beam of monopolar charged particles, regions of the field having curved field lines, are modified to significantly linearize the field lines in the area of the beam. An additional flux density field is superimposed on the primary flux density field so that the field lines interact in an harmonic synthesis and so that the field lines of the resulting field in the region of interest, extend linearly. In this way, the deflection force on the beam is essentially independent of the beam position in the field direction and in the linearized region.
