Title: Programmed swimming bath heating system - uses low and high temp. heat exchangers for producing measured heat input
Inventor: JACKISCH WALTER DIPL ING
IPC: E04H4/12
Filed: 1980-02-13
Abstract: The water (4) in a swimming bath basin (2) normally recirculates through the drain pipe (3), filter unit (5) heat exchanger (6) with heat pipe connected to the central heating system of the building, pump (10) and a return duct (8). This flow system keeps the water at a steady luke-warm temperature of about 12 degrees C. A similar heat exchanger (14) is also arranged in the vertical heater vessel (12) whose height to diameter ratio is large. When the processor (24) which can be programmed with the aid of a keyboard (24) causes the electro-heater (13) to be switched on at a predetermined time, it produces a measured input of heat to the water (11) calculated on the basis of the initial water temperature, final desired basin temperature, duration of swim, and relative water quantities in basin and heater. The processor opens the valve (23) of the pipe (22) to permit a very rapid discharge into the basin.

Patent DE-3014051-A1 (DE)
Inventor: JAEGER WALTER DIPL PHYS
IPC: H04N3/28
Filed: 1980-04-11
Abstract: To avoid image disturbances in an electronic image transmission as far as possible or entirely, the motive (1) to be transmitted is imaged by means of an optical imaging system (2, 3) simultaneously as two images on the photo-sensitive layer of an optoelectronic transducer (4, 5). The latter converts these two images into two electrical signals frequencies given in time by means of scanning by an electron beam (6, 7). These signal sequences are sequentially stored on a magnetic tape (10). During the later replaying of the magnetic tape (10), the changeover switch (12) causes in each case two signal sequences in each case associated with one another to be present again at the same time. These two signal sequences present at the same time are compared with one another by means of the circuit arrangement (13) and when a predetermined difference between the signal strength of the signal corresponding to the same pixel is exceeded, only the signal corresponding to a lesser brightness is forwarded. <IMAGE>

Title: Method for producing a pulse sequence for driving a thyristor, and circuit arrangements for carrying out the method
Inventor: BRAJDER ANTONIO DIPL ING
IPC: H02M1/08
Filed: 1981-03-31
Abstract: In the case of the method according to the invention, the start of each pulse is defined by the point at which a first triangular-waveform voltage (UD) intersects a control voltage (USt). The end of each pulse is defined by the point at which a second triangular-waveform voltage (UD'), which is displaced in magnitude in comparison with the first, intersects the same control voltage (USt). The length of each pulse can thus be defined by the shift between the second triangular-waveform voltage (UD') and the first triangular-waveform voltage (UD). Only a reference voltage source (Uref) (which is present anyway in many circuits) and a resistor are required for this shifting, so that the shift and thus also the length of each pulse can be predetermined exactly. This method can be implemented using the two comparators (1, 2), the first comparator (1) comparing the first triangular-waveform voltage (UD) with the control voltage (USt), and second comparator (2) comparing the shifted triangular-waveform voltage (UD') with the control voltage (USt). The comparators (1, 2) advantageously have open collector connections so that the outputs can be linked together with a clock transmitter (11) to form a "wired-and". The pulses can thus be chopped into chain pulses in a simple manner. <IMAGE>

Title: Method for testing the tooth profile of toothed wheels and device for carrying out this method
Inventor: BERTZ HANS ULRICH
IPC: G01B21/20
Filed: 1981-06-30
Abstract: The invention relates to a method for testing the tooth profile of toothed wheels and to a transportable measuring device for carrying out this method. The influence of inherent faults in the tooth system on the positional determination of the measuring device is reduced by inserting the orientation sensor of the measuring device into various tooth spaces and determining the actual position of the measuring device from this by forming averages. The transportable measuring device for carrying out this method is distinguished by having a rotary slide valve guidance of the orientation sensor. As a result, the orientation sensor can also be inserted into tooth spaces situated relatively far away, without the need for the long guide tracks normal with compound-rest slides. In addition, the weight of the measuring device is reduced thereby.

Title: Method and arrangement for transport of waffle sheets
Inventor: WENDT HANS-JOACHIM DIPL ING
IPC: B65G47/51
Filed: 1981-11-19
Abstract: The invention relates to a method for the automatic transport of waffle sheets in an interlinked waffle production installation. The aim of the invention consists in economically better utilising an application machine which works according to the contact process. The object of the invention is to develop a method for the automatic transport of waffle sheets from waffle baking lines consisting at least of two automatic waffle baking machines and associated waffle sheet removals with pressure releases with an application machine which works according to the contact method without separate cover sheet supply. Waffle sheets arriving from a first waffle baking line are transferred in an uncontrolled manner to a collecting belt, while others only pass freely onto the collecting belt in a controlled manner when the place to be occupied is free. The waffle sheets lying at irregular spacings are supplied to a supply belt, individual surplus waffle sheets being transferred to an intermediate store in the event of too dense an order by special arrangements and controls. The application machine receives only as many waffle sheets as it can process. <IMAGE>

Title: Device on motor vehicle trailer combinations for steering the trailer
Inventor: LUETJEN HELMUT
IPC: B62D13/02
Filed: 1981-12-21
Abstract: In a device on motor vehicle trailer combinations for steering the trailer, consisting of two live rings arranged coaxially over the front trailer axle, the upper live ring of which is connected via a drawbar or forked drawbar to the motor vehicle, the object is to be achieved of providing a very simple mechanical device for steering the trailer which cannot only be coupled and decoupled easily but is also characterised by the fact that it can be adjusted in such a way that the trailer runs exactly in the tracks of the motor vehicle and thus exhibits a steering behaviour which is identical to that of the motor vehicle. The invention achieves this object by clamping crosswise two pieces of cable between the lower live ring of the trailer and two cable mounting devices attached under the rear part of the motor vehicle. These two pieces of cable assume the steering of the front axle of the trailer. This is an extremely simple construction.
