Title: Method for forming a heating element by means of a heating wire which is placed on an adhesive film
Inventor: ALTMANN DIETER
IPC: H05B3/36
Filed: 1981-08-14
Abstract: The invention relates to a method for forming a heating element, in the case of which a heating wire, which is in general thin, is fixed in a thicker adhesive film or the like. These heating elements are intended to rest smoothly on the rear surface of the mirror glass and, if relatively thin wires are used, are also intended to rest smoothly thereon in order to hold it, once the covering paper has been removed. The production of such elements using multi-needle nail templates is costly as a result of the necessary cleaning off of the adhering adhesive residue. Furthermore, the multi-needle increases the distortion of the element when the heating conductor is being pulled off and displaced. The aim is to preclude these disadvantages. The solution provides that the heating wire (7) is placed on a surface (which is equipped with anti-adhesion coating) of a working panel (1) (which remains stationary during the fixing) around pins (4) which are guided such that they can slide through said working panel (1) in the axial direction. The length of the pins (4) emerging from the working panel (1) exceeds the diameter of the heating wire (7), and the end length exceeding this diameter is tapered. The adhesive film (8) allocated to a pressure plate is guided against the free pin ends (5) of the pins (4) and forces said pins (4) through the film (4) into the working panel (1), with the heating wire being released. The pins are arranged in a stationary manner in a baseplate (2). <IMAGE>

Title: Process for preserving the freshness of foods
Inventor: TALLAFUS OTTMAR
IPC: A23L3/36
Filed: 1981-10-10
Abstract: Without preservation measures, water-containing foods keep for only a relatively short period from a few hours to about two days. However, with the use of known preservation measures, the flavour quality of these foods is changed. The invention provides a possible method for preserving the freshness of such foods over a considerably longer period, which is achieved by shock-freezing the foods and then packaging them in gas-tight portion bags under an inert protecting gas atmosphere.
Patent DE-3140468-A1 (DE)
Title: Device for sorting out impurities and a sorting-out method
Inventor: GRUEN GUSTAV
IPC: B07B4/02
Filed: 1981-10-12
Abstract: The invention relates to a device for sorting out impurities from granular vegetable products, especially for removing threads of jute or similar sack parts. The rake-like devices normally provided to carry out this task are unsatisfactory, as cleaning the rake causes problems, especially because the impurities take the form of long fibres and because of the associated danger of felting, as a rule making expensive structures with oscillating parts necessary. The aim of this invention is therefore to specify a device which permits good sorting of the material while only using rotating machine elements and having appropriate air guides. This object is achieved by constructing a conveying trough (3) which is equipped with a sorting worm (12) and in the semi-cylindrical floor of which there are formed a suction nozzle (4), which extends along the length of the worm and has an adjustable width, and, connected to the worm region, a box-like foreign body discharging structure (6). Charging is via a cellular wheel sluice (2). Beneath the sorting worm (12) there is arranged a worm (16) for collecting the cleaned raw product, which moves in the opposite direction to the sorting worm (12). The fine particles are sucked up by the suction fan (8). <IMAGE>

Patent DE-3202179-A1 (DE)
Title: Gear-change and/or charging pump for an automatic transmission
Inventor: HAERLE HERMANN
IPC: F04C15/00
Filed: 1982-01-25
Abstract: In an automatic transmission which is combined into one unit with a speed or torque converter, the housing of the charging and gear-change pump is attached to the converter-side wall of the transmission. The inner rotor of the pump, which is designed as an internal gear pump, is mounted on a supporting sleeve projecting from the inner wall and supporting the stator of the converter and is driven on the principle of the dog clutch by the hub of the converter pump impeller surrounding the supporting sleeve. The pressure oil to be fed into the converter by the pump is forced radially inwards by the high pressure part of the pump working space and - at least in large part - axially through the bearing of the inner rotor, the said bearing being designed as a multi-surface sliding bearing, into the annular gap between the hub and the supporting sleeve.
Patent DE-3202796-A1 (DE)
Title: Non-return valve, especially a delay valve for a closing movement, controlled by the intake manifold vacuum, of the carburettor throttle valve of internal combustion engines
Inventor: SCHULZE GERHARD DIPL ING
IPC: F16K15/14
Filed: 1982-01-28
Abstract: Such a non-return valve has a valve seat having through passages and an umbrella-shaped valve body designed as a diaphragm, the lip-like edge of which covers the through passages, the valve body being fixed on the valve seat by means of a central fixing socket passing through the valve seat and the fixing socket having a passage running through it. The orifice of the passage is formed as a seat for an additional valve, actuatable independently of the diaphragm-shaped valve body. A non-return valve of this design allows the expensive electrical reversing valve used on existing systems for the intake manifold vacuum-controlled delayed closing of the throttle valve of carburettors in internal combustion engines to be dispensed with, since its function can now be directly assumed by the additional valve incorporated according to the invention. The non-return valve according to the invention has the advantages of a compact construction and thereby also of a lower weight than corresponding single valves. The valve according to the invention is also less prone to faults than corresponding single valves, since there are fewer possible air leakage points and fewer components. In addition the valve according to the invention facilitates installation and maintenance.

Title: Method and circuit arrangement for changing the speed of a single-phase induction motor
Inventor: OKUBO ATSUSHI DIPL ING
IPC: H02P27/02
Filed: 1982-06-03
Abstract: The invention relates to a method for changing the speed of a single-phase induction motor which has a main winding and an auxiliary winding and whose auxiliary winding is connected in series with at least one capacitor during operation at the high speed corresponding to the mains frequency. A change in speed without a special design of the motor is thus possible in that a voltage at the mains frequency is supplied to the main winding and to the auxiliary winding (41 and 42) during operation at high speed, the capacitor, which consists of two capacitor units (8 and 9) being connected in series with the auxiliary winding (42), and in that, in order to change to the lower speed, a voltage is supplied to the main winding and to the auxiliary winding (41 and 42) by means of in each case one frequency reducer which is connected in series with these windings, the frequency of which frequency reducer is less than the mains frequency. As a result of the frequency reducer being driven in a phase-shifted manner, the voltages which are supplied to the main winding and to the auxiliary winding (41 and 42) are phase-shifted with respect to one another. In each case one of the two capacitor units (8 and 9) is connected in parallel with the main winding and the auxiliary winding respectively (41 and 42 respectively). <IMAGE>

Title: Pulsating water-jet device
Inventor: TIMOSENKO GRIGORIJ MARKOVIC
IPC: B26F3/00
Filed: 1982-06-11
Abstract: The pulsating water-jet device contains two jet pipes (20, 21) for successively feeding a pulsating liquid jet in the direction of the object to be destroyed, a flow interrupter (2) with an inlet for the operating liquid and two outlets for feeding the latter to the jet pipes (20, 21), and a pulse generator. The pulse generator includes a receiving housing (41, 42), a separating element, two stroke limiters (53a, 54a) for the separating element and a means for delaying the displacement of the separating element. The receiving housing (41, 42) is hydraulically connected to the jet pipes (20, 21), and the separating element oscillates between two end positions in relation to the jet pipes (20, 21) and generates a pulse in one of these end positions, in which.........as a result of the changeover of the flow interrupter, after the operating liquid pressure in the respective jet pipe (20 or 21) has risen to the predetermined value. The means for delaying the displacement of the separating element is, for example, a pipe (8, 9) which is under the pressure of the feed source or at least two cylindrical compression springs or a cup closed by a diaphragm and filled with compressed gas. As a result of the rise of the operating liquid pressure in the respective jet pipe (20, 21), the separating element reaches one of its end positions for pulse generation only after the pressure in this jet pipe (20, 21) has risen to the predetermined value. <IMAGE>

Title: Arrangement for regulating a three-phase asynchronous machine
Inventor: BLOECHER CHRISTIAN
IPC: H02P21/08
Filed: 1982-08-26
Abstract: The invention relates to an arrangement for regulating a three-phase asynchronous machine which is supplied from a converter having a current intermediate circuit (I converter). The components of the regulating device include a decoupling network, a higher-level setting-frequency control loop, a lower-level slip-frequency control loop, and an actual value computer. In order to improve a dynamically high-quality control method, which is known per se, by means of practically-related new arrangements, and in order to specify simple dimensionings, in technical equipment terms, for the regulator parameters, it is proposed according to the invention that the rotor flux linkages  psi R are also determined in the actual-value computer and that the regulating variable  gamma R, which is proportional to the slip ring frequency, and is produced from the quotient of the internal torque mi divided by the square of the rotor flux linkages psi R is held equal to the preset value  psi R* for virtually all operating states, in that the decoupling network which is matched to the lower-level slip-frequency control loop supplies the desired values for the stator current is* and the additional frequency f epsilon *.
