Title: System for reducing co-channel interference in cellular mobile radio networks with adjacent radio areas of extremely differing sizes
Inventor: MEIER WERNER
IPC: H04W16/24
Filed: 1981-07-30
Abstract: In mobile radio systems with cellular radio area division, direct adjacency of radio areas of extremely differing sizes may occur, typically in peripheral zones of built-up areas. If the known seven-frequency distribution plan (honeycomb structure) is taken as a basis, this frequency distribution can no longer be sustained in peripheral zones since the smaller radio areas are so physically close to substantially more powerful transmitters of the large radio areas that co-channel interference in the smaller radio areas assumes unacceptable proportions. It is proposed to implement the radio coverage of large radio areas which are directly adjacent to small radio areas not by means of centrally located radio concentrators with omnidirectional antennas, but to have these areas jointly supplied with the aid of sector antennas which are allocated to the radio concentrators of the small adjacent areas. <IMAGE>
Patent DE-3130570-A1 (DE)
Title: Electric clock
Inventor: KLUGER GOETZ-UWE
IPC: B60Q3/04
Filed: 1981-08-01
Abstract: An electric clock (4) is arranged near the interior lamp (7) in a motor vehicle. The stepping motor (3) of the electric clock (4) is connected between the terminal (30) and the vehicle frame. The clock illumination (5) is likewise supplied with voltage from the terminal (30) by means of a momentary-contact switch (13). The momentary-contact switch (13) is assigned a holding current circuit with a relay (17), so that after release of the momentary-contact switch (13) the supply of voltage to the clock illumination (5) is maintained. Connected in parallel with the relay (17) is a wiring (cable) run (20) which has a diode (21) and leads to the contact (11), on the side of the interior lamp, of the door contact switch (9). As a result, when the door contact switch (9) is closed, the relay (17) is short-circuited. The relay thereby drops out, so that the supply of voltage to the clock illumination (5) is interrupted. Since in any case a line to the interior lamp runs from the terminal (30) and from the contact (11) of the door contact switch (9), because of the invention the electric clock (4) only needs to be connected to lines in the adjacent interior lamp. <IMAGE>

Title: Consumption measuring device for motor vehicles
IPC: G01F1/08
Filed: 1981-08-25
Abstract: A consumption measuring device for the fuel consumption of a motor vehicle contains an evaluation circuit to which two flow meters (10, 11) can be connected. The flow meters produce pulses which correspond to the flow are counted by one counter (42) in each case. At regular intervals, the count values (f) of the counters (42) are fed as corrected count values (f') to a difference forming circuit (46) via memories (44) in which a correction curve is stored, the said difference forming circuit (46) producing an initial value (d) which corresponds to the difference in flow rates of the two flow meters (10, 11). This initial value is multiplied in a multiplier (49) by a proportionality factor (k) and subsequently indicated as a consumption value on a display device (53). The entire consumption from a specific time on is stored in an accumulator (52) in which the initial values (d) of the difference forming circuit (46) are added together. This entire consumption can also be indicated on the display device (53) after multiplication by the proportionality factor (k). <IMAGE>

Title: Hydraulic brake master cylinder
Inventor: ALAZE NORBERT
IPC: B60T11/16
Filed: 1981-09-22
Abstract: A piston of a hydraulic brake master cylinder (1) is proposed, the primary cup seal (3) of which is supported on its back by a ring (9) of sintered material. At the same time the sintered material ring (9) may be clamped between a piston shoulder (8) and the primary cup seal (3). In addition the sintered material ring (9) may replace a conventional intermediate washer. Finally, it is also possible to manufacture the piston (2) itself together with the ring (9) at least largely in one piece from sintered material. In this way the piston (2) of the master cylinder (1) is simplified, because no bores have to be made and the intermediate washer can be omitted. The hydraulic brake master cylinder is intended for brake systems of motor vehicles. <IMAGE>

Abstract: A device for determination of the fluid quantity passing through a flow cross-section per unit time with the aid of the differential pressure determined in an orifice measuring section is described, the device containing a display, designed as a system of coordinates, in which the quantity passing through is displayed on the ordinate and the differential pressure is displayed on the abscissa. In order to be able to determine as quickly as possible the fluid quantity passing through a flow cross-section per unit time it is proposed that the display (12) be a part of a baseplate (1) and the ordinate be plotted on an endless strip (7) which is tensioned by guide devices (8, 9) fixed to the baseplate (1) and is mounted in the guide devices so as to be displaceable therein relative to the baseplate (1). A runner (13), displaceable in the ordinate direction, with a marking (17) that can be set to a value of an orifice cross-sectional area is fixed to the baseplate (1). <IMAGE>

Title: Closure device for bottles
Inventor: MAIER HANNS-JOACHIM
IPC: B65D41/62
Filed: 1981-12-21
Abstract: The closure device is intended for bottles of sparkling wine which contain a pouring bead, which bounds the bottle opening and projects radially over the bottle neck, and a retaining bead which is separated from the pouring bead by a circumferential groove, projects radially over the bottle neck and has a larger outside diameter than the pouring bead. The device contains a stopper, which can be inserted in the bottle mouth and preferably consists of a cork, and a cap surrounding the bottle mouth. In order to allow reclosure of the uncorked bottle, the cap is constructed as a plastic moulding which is separate from the stopper and can be pushed onto the pouring bead under elastic prestress with a cylindrical shell part which is open on one side up to the stop of its opening edge against the upper annular shoulder of the retaining bead. The wall thickness of the cylindrical shell part corresponds essentially to the difference between the outer radii of the two beads, such that a smooth flush transition results between the outer surface of the cap and the outer surface of the retaining bead. <IMAGE>

IPC: B07B1/12
Filed: 1981-12-24
Abstract: The present invention relates to a sorting device for a weighing and packaging device having a number of feed channels, for lumpy goods, in particular fruit, vegetables or the like. In order to keep the fruit ultimately supplied to a packaging unit as small as possible, in order to work close to the desired weight, a so-called worm roller taring device has thus far been used, which occupied a lot of space and also partially damaged the fruit and the like. The sorting device according to the invention provides a remedy here, as webs or elongate fingers are connected to a vibration frame, which as a result of their shape and method of operation feed the fruit according to size to different or the desired channels.
