Title: One-part mirror blind
Inventor: FEUERBACH PETER
IPC: E06B9/04
Filed: 1982-10-15
Abstract: The blind is intended for inward swinging windows and serves to improve the soundproofing and the security against break-in while at the same time reducing heat losses through the windows at night and increasing daylight penetration. The mirror blind is hinge-mounted on the window base, can be swung outwardly from the vertical into the horizontal and aligned at a desired angle with respect to the sun using a twin-frame system. The blind has the following structure from the inside outwards: mirror, soft insulating panel, stable waterproof panel, which are adhesively bonded to one another and sealed in a light metal frame. The application is suited equally for windows of dwellings or for larger units, such as, for example, greenhouses whose roof structures are not transparent. The mirror blinds combine relatively inexpensive manufacturing cost with advantages which can otherwise only be achieved, in combination, using systems which comprise a blind, insulating glazing and a light trap. Subsequent fitting to many types of windows is possible.

Patent DE-3315972-A1 (DE)
Title: Valve
Inventor: JOHNSON TERENCE L
IPC: F16K31/40
Filed: 1983-05-02
Abstract: The subject of the invention is a valve having a valve body (15') with an inlet (27), an outlet (28) and a valve opening (30) between inlet and outlet, which opening is surrounded by a valve seat (31). A valve element (35) can be brought into and out of interaction with the valve seat in order to open and close the valve. The valve element can be made to oscillate in order to produce a reduced flow rate for the flow medium to be carried through the valve. The valve element may be assigned a final control element (34), which may be assigned to an electric solenoid. If the solenoid is excited by the full wave of an alternating current, the valve is held stably in an open position. If the solenoid is excited by the half-wave of an alternating current, the valve body oscillates. The valve is preferably used as a pilot valve of a main valve (10), the valve element then being made to oscillate in order to have a reduced flow rate through the pilot valve when the main valve is closed. <IMAGE>

Title: Circuit arrangement for improving the stereo sound impression of the sound signals radiated by audio or television devices in two separate channels
Inventor: GOETZ LASZLO
IPC: H04S1/00
Filed: 1983-07-02
Abstract: A circuit arrangement is described with the aid of which the stereo sound impression of sound signals is improved which are radiated by audio or television devices in two separate channels. The circuit arrangement contains a first transmission path for the signals of one channel and a second transmission path for the signals of the other channel. A third transmission path is provided which receives the sum of the signals transmitted in the two channels and conducts them through a delay section (12). A first summing element (R1, R5, 8) adds the output signal of the delay section (12) to the signal transmitted in the first transmission path and outputs the sum generated as output signal of one channel. A phase rotating element (14) rotates the phase of the output signal of the delay section (12) by 180 DEG . In a second summing element (R2, R6, 9), the output signal of the phase rotating element (14) and the signal transmitted in the signal transmission path are added together. The second summing element outputs the sum generated as output signal of the other channel. <IMAGE>

Title: Device for determining a temperature value by means of at least one temperature-dependent sensor resistor
Inventor: JOERGENSEN IVER
IPC: G01K7/20
Filed: 1983-08-27
Abstract: A device for determining a temperature value by means of at least one temperature-dependent sensor resistor (F1, F2) has an evaluation circuit which processes a voltage drop dependent on the temperature of the sensor resistor. Together with two fixed calibration resistors (G, D), the sensor resistor (F1, F2) is connected in series to a common current source (1). The basic resistor (G) has a lower calibration value (Re1), which the sensor resistor assumes given a prescribed lower temperature. The difference resistor (D) has a difference calibration value (Rd) of a magnitude such that the series circuit of the calibration resistors has an upper calibration value (Re2) which the sensor resistor assumes given a prescribed higher temperature. The evaluation circuit determines the actual temperature value from at least one measurement voltage drop (Vf1, Vf2), taking account of a calibration characteristic which results from at least one calibration value (Re1, Re2, Rd) and the associated calibration voltage drop (Ve1, Ve2, Vd). This leads to a very simply constructed device which is easy to adjust. <IMAGE>

Patent DE-3402229-A1 (DE)
Title: Combination chamber equipped with a curing smoke generator for smoking, cooking and roasting
Inventor: SCHMIDT EDWIN
IPC: A23B4/052
Filed: 1984-01-24
Abstract: To improve the treatment of the circulating air stream of a combination chamber and for its more intensive action on the material to be treated, the ventilator space is partitioned diagonally and furnished with a smoke hole. Heating, drying or moistening of the circulating air stream is carried out directly prior to entry into the chamber interior. The usable space of the combination chamber can be reduced by inserting a false bottom. Exothermic reactions are avoided by the curing smoke generated escaping downwards directly from the pyrolysis site. An air stream can thus have absolutely no contact with the pyrolysis site.

Patent DE-3418738-A1 (DE)
Inventor: FORCH HANS DIPL ING
IPC: F16J15/3244
Filed: 1984-05-19
Abstract: In the combination of a shaft with a polymeric ring having a sealing surface which flares against a counter surface on the shaft to form a dynamic sealing zone therebetween upon relative rotation of the shaft and ring, both the sealing and counter surfaces have hydrodynamically-acting feed-back elements for pumping fluid which seeps between the surfaces upon the relative rotation. The resultant, net axial component of pumping actions of the elements is in one axial direction along the shaft to pump the fluid back into the space from which it came, but the elements have different pumping actions. The different pumping actions produce a fluid circulation in the dynamic sealing zone which inhibits seal-wearing granular deposits.

Title: Feed dispenser for fish
Inventor: LOECKER ERWIN
IPC: A01K61/80
Filed: 1984-05-23
Abstract: The invention relates to a feed dispenser for fish, in which the feed (55) can be removed in portions from a stock container (1) having an outlet pipe (2) in its funnel-shaped bottom and introduced into the water (24) containing the fish. To this end, an outlet pipe (4 or 44) is pivotally connected to the outlet connector (2) and is regularly pivoted by a drive (7 or 30) from a first end position into a second end position. When this occurs, the outlet pipe (4 or 44) adopts such an attitude, in the first end position, that only a certain quantity of feed slides out of the stock container (1) into the region of the pivotally attached end of the outlet pipe (4 or 44). In the second end position, the outlet pipe (4 or 44) adopts such an attitude that the feed (55) slides out of the outlet pipe (4 or 44) and enters the water (24) containing the fish. As a result of this design of the feed dispenser, the quantity of feed to be supplied to the fish can be exactly metered. <IMAGE>
