Title: Integration of heat pumps into installations for generating heating water and service water
Inventor: VONHOFF JUERGEN
IPC: F24D19/10
Filed: 1981-08-12
Abstract: Electric heat pumps with alternating-current drive of modular sizes (2, 3, 5 and 5) kW for service water or heating water or combined service/heating water devices are described. For their automatic and economical interaction with one another or a boiler, a control and regulating circuit is indicated. This ensures that, in the case of a relatively warm outside temperature, only the respectively smallest unit works and, in the case of the outside temperature falling further, further heat pumps and/or a boiler are switched on. In the case of the outside temperature increasing again, the individual heat generators are switched off in reverse order. The limit temperature of e.g. +3 DEG C outside temperature, as of which only the boiler is intended still to work, can be modified by a potentiometer. In order to prevent an uneconomical rapid switching on and off of the heat-generation units, time delays are provided in the circuit, which ensure that the control input pulses have their control effect in a delayed manner both in the rising and in the falling direction. For the service water production, a priority circuit is provided which switches the heat pump over from heating operation to hot-water operation in the event of a demand for service water.

Patent DE-3141476-A1 (DE)
Inventor: BUCHHEIT OTTO KARL
IPC: B65G57/18
Filed: 1981-10-20
Abstract: A feed roller table with rollers (11a) is divided into partial widths (A and B). The rolled shapes to be stacked are passed onto the feed table in layers of different numbers of bars n and n-1 and are braked during bar movement by elevation of braking skids (38 and 41). The skids of one series of braking skids (41) are designed to function as turnover magnets and may be rotated 168 DEG  to a position above another series of skids (38) in order that de-energization of the turnover magnet braking skids (41) will permit an interlocked layer of rolled shapes to be formed on the other braking skids (38). This double layer of bars is picked up by horizontally shiftable receiving magnets (43) and deposited on stacking table arms (49) which index downward into a position (49') below the level of the stacking roller table for rotation through 90 DEG  to pass horizontally underneath the stack of bars exiting on the roller table and to return to the upper receiving position. Due to the fact that the diametrically opposed braking skids (38 and 41) may be rotated into a vertical position in which they are lowered between the partial widths A and B to a point underneath the table rollers (11a) to move back into the diametrical horizontal position without intersecting the level of the roller table, a new appropriately separated layer of bars may enter the stacking machine while the succeeding bars are still being braked on the braking skids (38 and 41).
Patent DE-3142513-A1 (DE)
Title: Saw shaper
Inventor: SORG JUN WILHELM
IPC: B23D45/00
Filed: 1981-10-27
Abstract: The saw shaper can be used on any circular saw bench to produce wooden plates or bowls as ornamental objects or objects of daily use. Owing to the simple and hence inexpensive construction, it may be of interest especially to amateur craftsmen and do-it-yourself enthusiasts. It takes about two to five minutes to change the plate and carry out a shaping operation. In conventional turning, this takes much longer. The method with the circular saw is easier to handle, requires little experience and skill and is relatively safe owing to the slow rotation of the workpiece. It is possible to produce without problems in particular large pieces having deep hollows and thin walls. Owing to the combination of different-sized saw blades as well as the arrangement of the cutouts, a multiplicity of shapes are possible. Even the working of angular and oval basic shapes presents no difficulties. (The shaping naturally always remains circular). The range of practical possibilities with conventional turning is facilitated and extended by the saw shaper.

Title: Atmospheric humidity measuring circuit for display and regulation
Inventor: MICHELBACH LUDWIG
IPC: G01N27/22
Filed: 1981-11-24
Abstract: Such a circuit is available and has a stabilised input voltage at a measuring circuit (2) which is designed as a differential pulse measuring circuit comprising two RC oscillatory circuits (14, 15), one of which contains a capacitive sensor (19) as capacitor. At the same time, it is desirable if the circuit is also suitable in a practically feasible way for regulating or controlling an apparatus as a result of supplying a sufficiently high output voltage, with the RC oscillatory circuits being unaffected by environmental precipitates. This is achieved if the output voltage (11) of the measuring circuit (2) acts on an amplifier circuit (3), an alternating voltage is applied to the input (4) of a stabilised and voltage-limiting rectifier circuit (1), one part of the output voltage of the latter forming the input voltage of the measuring circuit (2) and the other being applied to the amplifier circuit (3), and the resonant frequency of the RC oscillatory circuit (14, 15) is in the 100-150 kHz range as a result of choosing suitably small values of the resistors (18, 22). This circuit can be used in conjunction with a regulator (41), an actuator (42), a plotter (46) and/or two displays (43, 44) by feeding the output voltage (40) of the circuit directly to these instruments. <IMAGE>

Filed: 1982-04-03
Abstract: Integrierter Schaltkreis mit einem System oder einer Serie oder einem Feld von Transistoren, die mit jeweils einer Elektrode gemeinsam an eine Leiterbahn angeschlossen sind, welche einen Teil des integrierten Schaltkreises bildet. Die Elektroden der Transistoren liegen im Abstand längs der Leiterbahn und weisen abnehmende Länge in einer gegebenen Richtung bezogen auf die Leiterbahn auf. Die Leiterbahn ihrerseits besitzt eine entsprechend zunehmende Breite in der gegebenen Richtung. Die Längenabnahme der Elektroden und die Breitenzunahme der Leiterbahn sind so bemessen, daß die Elektroden und die Leiterbahn gemeinsam eine allgemein rechteckige Kontur definieren. Unterschiede in den Einschaltspannungen für die Transistoren, herrührend von Unterschieden in ihrer Elektrodenlänge, tendieren dahin, den Spannungsabfall über der Leiterbahn zu kompensieren, so daß man aus den Transistoren des Systems gleichförmige Ausgänge erhält. Ein Bereich bildet eine in Sperrichtung vorgespannte P-N-Schicht, um Schaltkreiselemente in dem integrierten Schaltkreis voneinander zu isolieren, und dieser Bereich wird benutzt als Teil einer leitenden Strecke zur Schaltkreismasse und besitzt einen Oberflächenkontaktbereich gleichen Leitfähigkeitstyps und höherer Dotierung als der in Sperrichtung vorgespannte P-N-Schichtbereich. Der integrierte Schaltkreis gemäß der Erfindung ist besonders nützlich für die Ansteuerung eines Thermodruckkopfes.
