Title: Electrical hotplate
Inventor: SCHREDER FELIX
IPC: F24C15/10
Filed: 1981-11-10
Abstract: In addition to its main heater (12) of normal power, which is controlled manually by a power control element (17), an electrical hotplate (11) has an additional heater (13), which is connected in parallel with the main heater (12) and in series with a temperature switch (15) and with an additional contact which is operated by the adjusting shaft (21) of the power control element (17) in an upper or medium power range of the hotplate (11). The temperature switch is a temperature limiter which operates with a relatively large amount of inertia and has a large amount of switching hysteresis, which in this case is used as a timer which normally no longer switches on once it has been switched off. Continuously adjustable pulsed power control apparatuses and seven-position switches are provided, inter alia, as the power control elements (17). <IMAGE>

Patent DE-3150203-A1 (DE)
Title: Method and arrangement for generating coded image signal values and for recovering the image signals
Inventor: WENDLER THOMAS DIPL ING
IPC: H04N19/60
Filed: 1981-12-18
Abstract: The coded image signals are obtained by means of transformation coding in a manner known per se, by applying the Walsh-Hadamard transformation to initially in each case four adjacent picture elements, and thereafter to in each case four adjacent sum coefficients which are written back into the frame buffer or an intermediate buffer time and again whilst the remaining coefficients are directly stored in an image archive memory. After a preselected number of such processing steps, the sum coefficients are then also stored. For recovery, the sum coefficients last stored are first read out and written into the frame buffer so that an image having a coarse resolution appears. These coefficients and the high-order coefficients in each case previously stored in the frame buffer and now read out again, are used for recovering an image having a resolution which is higher with each processing step. When images are searched, the recovery can be aborted when an image having the corresponding resolution shows that this is not the required image so that the search process is relatively fast since the last processing steps for obtaining the highest resolutions take the longest. <IMAGE>
Patent DE-3202266-A1 (DE)
Title: Hydropneumatic preassembly device for non-soldered pipe unions
Inventor: SINNING HANS-DIETER
IPC: B23P11/00
Filed: 1982-01-25
Abstract: The invention relates to a preassembly device for non-soldered pipe unions. The preassembly of the cutting ring has hitherto been carried out in such a way that the union nut was used as abutment for a preassembly connection-piece (5), which resulted in the fact that the preassembly connection-piece (5) could be manufactured only with low wall thickness and led to premature wear and leaky unions. According to the invention, a guide bush (11) consisting of half-shells (8) is used as the abutment, and this guide bush (11) is mounted on stop plates (9, 9a) which can be opened and which, for their part, are mounted axially displaceably on a base plate (10). <IMAGE>

Patent DE-3215327-A1 (DE)
Title: Natural intestine cleaning device
Inventor: SCHMID ALFRED
IPC: A22C17/16
Filed: 1982-04-24
Abstract: The natural intestine cleaning device shown in the illustration is for use in slaughterhouses and butcher's shops and serves for cleaning and for turning pig large intestines and beef mid-intestines for sausage manufacture. Instead of the complicated cleaning of the intestines by means of water tube and subsequent emptying of the intestine contents, during which breakage of the intestine is not infrequent, the intestine is cleaned in the most simple manner using the novel intestine cleaning device. The intestine is drawn downwards over the nozzle head with inclined pipe, cleaning water being sprayed onto the internal wall of the intestine by means of a foot valve. During this process, the intestine is constantly emptied. On drawing back over the nozzle head, the intestine is rinsed. With this device, the sides of the natural intestines can also be changed over very simply. Without water, the intestine is attached with a short extension to the nozzle head and the remaining part of the intestine is slipped over the intestine extension onto the inclined pipe. The rustproof device is easy to handle and to clean. <IMAGE>
Patent DE-3217207-A1 (DE)
Inventor: ITO JIRO
IPC: G04C3/14
Filed: 1982-05-07
Abstract: A stepper rotor is driven with a narrow pulse width input which matches the load conditions on the motor. The subsequent position of the rotor is detected as being rotated or non-rotated by application of a detection pulse to the rotor. An additional driving pulse of increased width is applied should the rotor be found in a non-rotated state. A stabilizing pulse prevents intermediate rotor positioning. Position of the stepper motor is detected by passing a current through the rotor cell. The rate of increase in detection current is different when the rotor has rotated and when the rotor does not rotate because coil inductance and magnetic flux directions passing through the saturable portion of the stator are different depending upon the position of the rotor. The width of the driving pulse for normal operation is selected from a range of pulse widths so as to match the load on the motor.

Title: Method for signal emission using single-pin base fluorescent lamps, and a device suitable for said purpose
Inventor: SCHENKE GREGOR DR ING
IPC: H05B41/04
Filed: 1982-12-11
Abstract: In order to increase the useful life of single-pin base fluorescent lamps, especially with a high switching frequency as a result of signal emission, the respective switched-off time, i.e. the dark phase, is limited, and the switched-on time is simultaneously fixed at a minimum time. The switched-on time, i.e. the bright phase, is at least 1.5 times the dark phase. In order to carry out the method, the switching device has a module connected to it which has two thyristors connected in reverse-parallel. These thyristors implement the respective switching-on only in the voltage zero crossover. <IMAGE>
Patent DE-3303626-A1 (DE)
Title: Line simulation
Inventor: HERBERT HELMUT DIPL ING
IPC: H04B3/40
Filed: 1983-02-03
Abstract: The device to simulate telecommunications lines in order to carry out interference measurements comprises individual line sections which correspond to specific line lengths and are connected in series. The noise voltage feed-in point can be selected in steps over the whole range of the simulation according to the individual line sections. The respective feed-in point of the noise voltage source can be set by means of two rotary switches, by disconnecting the line simulation at the respective point and by looping the noise voltage source into the line. The disconnection is carried out using switching means which are assigned to the individual switch positions. Each switch position corresponds to a specific line section. Precautions are taken to ensure that the sum of the line sections which can be set by the two rotary switches does not exceed the overall length of the line simulation.
