Title: Spray-gun control system - uses oscillating armature controlled by pulse-width modulated excitation signal
Inventor: HAUSER WOLFGANG
IPC: B05B9/08
Filed: 1980-01-31
Abstract: The control system applies a pulse-width modulated excitation signal to the spray gun oscillating armature in order to reduce the liquid atomised per unit time by the gun. The excitation signal has a steep leading edge and a steep trailing edge. The steep edges are produced by switching a supply signal that varies slowly in comparison to the rise time of the pulses. The duty factor of the pulse-width modulated signal is increased whilst keeping the amplitude constant in order to reduce the peak power. The system ensures that the liquid is adequately atomised even at relatively low power.

Title: Pressure control for electropneumatic converters and positioners - uses air flow variations, corresponding to control current, effected by control current operated heater
Inventor: EBACH MANFRED ING GRAD
IPC: F15B5/00
Filed: 1980-06-28
Abstract: The control device allocates pressure values to certain current strengths by superimposing the variations of the control current onto a constant current flow. The variations of the air flow, corresponding to the control current, are effected by a heater fed by the control current. The prefered heater form is a resistive heating wire. The latter extends in a direction of an outlet throttle axis, mounted on an air flow duct. In front of this throttle the air duct incorporates a prethrottling valve with an amplifier in between. In such instance the heater may be formed a Peltier element so that the flow is cooled in the region of the prethrottling valve and heated in the region of the outlet throttle. The control device may be in the form of a replaceable component module, consisting of a support and two tubes, each with a heating wire.

IPC: G06F7/50
Filed: 1981-02-09
Abstract: The switchable full adder-subtracter according to the subject matter of the invention has two control lines s and i which are interconnected via a negating circuit. The AND circuits which are needed only for addition have an additional input which is connected to the addition control line s. The AND circuits which are needed only for subtraction accordingly have an additional input which is connected to the subtraction control line i. In this way, this computing unit can be switched from addition to subtraction and vice versa. The number 6 (LHHL) is added automatically before the addition in each decade and subtracted again before the display of the result number (sum). The subtraction is carried out without this cardinal number since no cardinal number is required here. Figure 1 shows type A of this computing unit and Figure 2 shows type B thereof. <IMAGE>

Title: Arrangement for data exchange between parallel microcomputers
Inventor: HOLZNER PETER ING GRAD
IPC: G06F15/16
Filed: 1981-02-11
Abstract: The invention relates to an arrangement for fast data exchange between two microcomputers or between two multi-microcomputer systems. A DMA controller (DC1) is allocated to one computer (COM1). The system bus (SB1) provides the connection between computer and DMA controller. A second DMA controller (DC2) is allocated to a second microcomputer (COM2). A second system bus (SB2) provides for the connection in this case. The two system buses are interconnected via a system bus isolating stage (TS). During the bus isolation, both computers can operate independently of one another. To exchange data, the microprocessors of the microcomputers are switched to the hold state (all connections to the system bus isolated), the system buses (SB1, SB2) are interconnected and one DMA controller handles the data exchange whilst the other DMA controller is deactivated. During the data exchange, for example, information is read out of the random-access memory of the second microcomputer (COM2) and loaded into the random-access memory of the first microcomputer (COM1). The control is handled by one DMA controller alone in this case and is very fast. <IMAGE>
