Title: Method and device for controlling the preselectable power supply for the cooking point of an induction cooker
Inventor: KLAPPER PETER DIPL ING
IPC: H05B6/06
Filed: 1987-02-04
Abstract: Method for controlling the selectable power levels for the cooking point of an induction cooker. In the case of induction-heated cooking points, the cooking process which is currently taking place is as a rule instantaneously interrupted when the heating-up power (boiling power) is turned down to a reduced continuous-cooking power (simmering power). The heating-up process is merged into the continuous-cooking phase by reducing the power in a step by step manner. In the case of induction-heated cookers, the method enables continuous cooking of the material to be cooked during the transition from the heating-up to the continuous-cooking phase. <IMAGE>

Patent DE-3717615-A1 (DE)
Inventor: LABSCHIES HARTMUT
IPC: G01G11/00
Filed: 1987-05-25
Abstract: In a method for continuously determining the delivery rate of a stream or flow of loose bulk material and/or for continuously dosing such material, the loose material is caused to travel along part of a circular path and is then removed from that circular path after travelling at least around a portion of a circle. The centrifugal force exerted by the loose material on the axis of rotation is measured and used to deterine the delivery rate. The centrifugal force is measured by sensing an excursion of a rotational axis of a measuring wheel caused by the centrifugal force exerted by the loose material continuously fed onto and removed from the rotating measuring wheel such that the material travels through a semicircle. Before being fed onto the measuring wheel, the material may be accelerated to the wheel's velocity. The centrifugal force resulting on the wheel axis is measured. An apparatus for carrying out this method includes appropriate drives for the measuring wheel, and arrangements for accelerating, feeding, and discharging the material, as well as a load cell, for example, for measuring the centrifugal force.
Patent DE-3718697-A1 (DE)
Title: Cooling arrangement
Inventor: HIESTERMANN KURT DIPL ING
IPC: F01P3/20
Filed: 1987-06-04
Abstract: A description is given of a cooling arrangement for an internal combustion engine (1) of a vehicle, especially a motor vehicle, which has a main conduit system (3, 4), connecting the internal combustion engine (1) to a radiator (2), having a coolant pump (5) and controlled by a thermostatic valve (6), and a bypass conduit system (11, 12), in which a coolant expansion tank (10) connected to the radiator (2) by way of a vent line (11) and to the coolant inlet of the internal combustion engine (1) by way of a return line (12) is provided. In order to shorten the warm-up time of the internal combustion engine by reducing the volume of circulating coolant, the coolant expansion tank (10) is to be divided into at least two coolant storage spaces (16, 17), of which only the smaller storage space (16) is connected to the coolant circulating in the bypass circuit when the main conduit system (3, 4) is shut off by the thermostatic valve (6). <IMAGE>
Patent DE-3719482-A1 (DE)
Title: Amplifier
Inventor: SCHUMANN ALFRED H G
IPC: H03F3/45
Filed: 1987-06-11
Abstract: Amplifier for forming the sum or the difference of at least two electrical input signals. The invention is based on the object of creating a wideband amplifier of the above-mentioned type, the output voltage of which is proportional to the difference or the sum of the input signals over a wide frequency range. The object is achieved by the fact that a transistor (10, 15) having in each case one emittor or source resistor (12, 16) is provided for each input signal, that the series circuits formed in each case of transistor (10, 15) and resistor (11, 16) are connected in parallel with one another and that this parallel circuit is connected in series with at least one further resistor (13, 14) for picking up the output voltage. Across the common third resistor constructed as load resistor, an alternating voltage which is proportional to the sum of the two alternating signal currents in the transistors is also chopped in addition to a direct voltage. This alternating voltage is the output signal of the amplifier. An advantage consists in that each signal branch only contains two components as a result of which the spread, particularly of the dynamic transfer parameters, is kept low. This results in an approximately equal transfer function for all signals up to a high frequency range. <IMAGE>
Patent DE-3726181-A1 (DE)
Title: Process for the superheterodyne reception of a modulated signal
Inventor: VOLLENWEIDER WALTER
IPC: H03D7/16
Filed: 1987-08-06
Abstract: In the superheterodyne receiver, the aerial 1 is followed by a prefilter 2, a preamplifier 3 and a premixer 4. The signal path then branches to the main mixers 5 and 6, which are in quadrature and the output signals of which are fed as intermediate frequency zero to the corresponding further inputs 5 and 6. These may be low-pass filters and further quadrature stages. The common local oscillator 9 supplies the three mixers 4, 5, 6 with an unmodulated signal of half the reception frequency, the phase upstream of the main mixer 5 being shifted through 90@ by the phase mixer 10. As a result, the oscillator signal cannot reradiate onto the aerial. The same isolating effect is obtained if, as a variant, different local oscillator frequencies are fed to the premixer 4 or possibly further premixers 4 on the one hand and to the main mixers 5, 6 on the other hand. A condition is that these frequencies deviate from the receiving frequency, so that interference voltages can be suppressed in the prefilter. There thus occurs a mixing down to zero in two or more stages. <IMAGE>

Patent DE-3740653-A1 (DE)
Title: Wide-band sound transducer system
Inventor: RIEDER JOACHIM
IPC: H04R9/06
Filed: 1987-12-01
Abstract: In the patent application having the title "wide-band sound transducer system", the design of a sound transducer having almost ideal characteristics is described. The fact is known that the most widely used sound transducer, an electrodynamic drive system with a cone diaphragm or a hemispherical calotte, is not ideal. However, this principle is very inexpensive. Other systems are partially better but, as a rule, much more expensive. The faults of these sound transducer systems become very noticeable in a negative way with the introduction of digital sound recording in the field of entertainment electronics. There have been and there are a great number of attempts at building a better sound transducer. The patent application deals with a design which is very promising. It is based on the idea that an elastic vibrating spherical surface does not have an acoustic short circuit, very low mass and ideal radiating characteristics. It does not need an enclosure and functions in a single system from less than 20 Hz to greater than 20 kHz. As a consequence of the new principle, completely novel design solutions are also possible. A sound transducer having these characteristics and a price which is certainly not higher than the conventional loudspeaker boxes will probably be sold in great numbers.
