Patent DE-3841731-C1 (DE)
Title: Process for coating a tool base, and tool produced by this process
IPC: C23C16/52
Filed: 1988-12-10
Granted: 1990-04-12
Abstract: Particularly for reducing the high coating temperatures and for improving the adhesion of the surface layer, it is proposed to use a plasma-activated CVD process with a pulsed direct voltage and a residual voltage, remaining in the pulse process, of a magnitude which is equal to or greater than the lowest ionisation potential of the gases participating in the CVD process, but is at most 50% of the maximum value of the pulsed direct voltage. The thickness of the layers should be at most 20 to 30  mu m, the base temperature during the coating being between 400 and 800 or preferably below 600@C.

Title: EEG learning head model
IPC: G09B23/28
Filed: 1989-01-02
Granted: 1990-08-02
Abstract: The magnetic EEG learning head comprises a fully magnetic polyester head and a set of round magnets with black/white marking, which can be arbitrarily distributed over the surface of the learning head in accordance with the rules of the international 10-20 system. The characterising feature of the fully magnetic plastic head is its special material consistency; due to a specific mixing ratio of polyester composition to incorporated proportion of fine iron chips a "magnetic effect" of the head is achieved. When the EEG hood is placed on the patient's head this learning head is intended to serve as a direct practical aid for finding and gauging the measurement and lead points which are important for the EEG recording.

Title: Anti-burglar installation for door or window - uses impact arm moving against spring force to act as pressure sensor releasing alarm
IPC: G08B13/02
Filed: 1989-06-13
Granted: 1990-10-25
Abstract: Any attempt at a break-in by applying pressure to the door or window equipped with this pressure-sensitive device leads to the activation of an alarm. The pressure-sensitive device consists of an impact arm mounted in a housing and guided by locating profiles to press against a spring. There is also another spring which can be adjusted to set a certain pressure on the arm and this pressure has to be overcome before the arm can be moved to activate the alarm switch. ADVANTAGE - Simple design, low cost and easily fitted.

IPC: G05B11/36
Filed: 1989-09-26
Granted: 1991-02-21
Abstract: A process for regulating a setting system (10) subject to friction is proposed in which the non-linear characteristic (20) of the position regulator (12) is fixed in such a way that the amount of the value Ns, Vs fed to the setting system (10) subject to friction with a regulation deviation  DELTA x produces a torque or a force which is sufficient to enable the setting system to break free from the moment of adhesion or adhesion and that the energy of movement of the setting system (10) can be eliminated in the target region (21). The additional use of an integral component preferably depending on the regulation deviation  DELTA x increases accuracy when stationary.

Title: Streamline control for variable pitch marine screw - has ring duct with smaller diameter than screw to reduce flow rate around hub and increase flow rate through propeller blades
IPC: B63H5/16
Filed: 1992-07-17
Granted: 1993-09-16
