Title: Circuit arrangement for contact switches
Inventor: KOCH FRIEDRICH DIPL PHYS
IPC: H03K17/14
Filed: 1981-04-30
Abstract: In the circuit arrangement proposed by the invention and the associated method, the side (13) of a basic capacitance (12) which is connected to the mains voltage and the second side (15) of which can be touched by an operator, is connected to an input (16) of a differential amplifier (17), the output (18) of which is connected to the second input (21) via a resistor (20). This input (21) is connected via a capacitance (24) to the mains voltage (22). By feeding back the output signals, a switching threshold of the differential amplifier is created which adjusts itself automatically and thus a self-regulating operating sensitivity of the circuit arrangement is created which is independent of temperature changes and the type of assembly of the contact area. In the case of a number of contact areas, the output signals of only one differential amplifier are preferably fed back to the inputs of a number of differential amplifiers. An annular contact area can be preferably provided which surrounds the other contact areas and is associated with a protective circuit which causes the remaining circuits to be blocked or otherwise switched off. <IMAGE>

Abstract: A freely programmable control system is disclosed which includes a computer, a data memory, and a program memory, as well as a program controllable logical network for individual bit processing and an individual bit memory. The disclosed control system operates as an integrated system which utilizes both commands for the computer and separate commands for individual bit processing. Both types of commands are stored in the program memory as an integrated program. During individual bit processing the commands for the individual bit operations are routed from the program memory to the logical network circuit for individual bit processing, and are there executed. Similarly, during computer processing the commands for the computer are transferred directly to the computer and are there executed. The commands for the individual bit processing are kept away from the computer by a switching circuit which operates to supply the computer with a command to increment the computer program counter for each individual bit instruction.

Title: Compressor
Inventor: SHIRAKUMA TAKASHI
IPC: F04B49/24
Filed: 1981-11-04
Abstract: A compressor has a main compressor section for compressing the gas drawn in from an intake chamber through an inlet shut-off element into a compression chamber, the gas after compression being expelled through an outlet aperture. The main compressor section is driven by a motor which is started by a switch. In order to reduce the starting load of the motor a solenoid mechanism is provided with a piston which is advanced when the switch closes and opens the inlet shut-off element, as a result of which the compression chamber is connected to the intake chamber and the main compressor section performs no compression work. A PTC thermistor is connected in front of the solenoid mechanism so that the solenoid mechanism is active only until the PTC thermistor reaches a certain resistance value. The invention allows a smaller and cheaper motor to be used for the compressor.
