Patent DE-2305682-A1 (DE)
Inventor: EFFENBERGER HUBERT DIPL ING
IPC: G04C3/00
Filed: 1973-02-06
Abstract: The display system (4) is driven by an electronically controlled drive device (5, 6, 9). The drive device comprises an unbalance system (5) which is controlled by an electronic switching device (9) and, via a gear (6) drives the display system constructed as a pointer mechanism. The unbalance system (5) can oscillate at a first or at a second frequency. Also present are a quartz oscillator (1) and an electric frequency divider (2). The output of the frequency divider is connected to one input of a bistable flip-flop (3). With each zero passage, the unbalance system generates a voltage pulse which is fed via a pulse-shaping stage (5a) to a further frequency divider (8). The output of the further frequency divider is connected to the other input of the bistable flip-flop. The two said frequency dividers are constructed such that the pulse frequency of the pulse trains fed to the two inputs of the bistable flip-flop deviate only slightly from one another. The electronic switching device (9) is controlled by the pulses occurring at the output of the flip-flop, whose width depends on the phase relationship between the said pulse trains, and the unbalance system is influenced to oscillate either at the first or at the second frequency. <IMAGE>

Title: Tubular superconducting cable - is made of niobium or titanium wires which are embedded in copper and supported in coolant
Inventor: HILLMANN HANS DIPL PHYS
IPC: H01L39/14
Filed: 1973-09-24
Abstract: Superconducting filaments are embedded in a normal conductor such as copper. This gives it added mechanical strength, the normal conductor being in the form of a rectangular section bar.

Title: Fluidised bed furnace adjustable gas nozzle - has sliding damper prevents clogging and cools furnace floor
Inventor: ALBRECHT ERHARD
IPC: F27B15/10
Filed: 1973-11-09
Abstract: A noozle for a fluidised be furnace projects upwards through the furnace floor to supply an upward flow of gas into the bed. The nozzle comprises a central, vertically guided pin capped by a flat disc and surrounded, below the level of this disc, by a fixed sleeve, with an annular space between the pin and this sleeve; the sleeve is fixed in the furnace floor and pref. its upper edge is higher than the furnace floor. The cross-section of the nozzle can be varied by rotating the pin and thus raising or lowering the cap; the outward flow of air or gas from the nozzle cools the immediately adjacent region of the furnace floor, so that this portion can be construed of heat-resistant steel instead of refractory material. A uniform supply of gas can be maintained over the entire area of the furnace floor adjusting the nozzles to compensate for local variations. The nozzles do not become blocked by the bed material.

Title: Bar screen collected material dewatered - by pressure or friction on rake and during passage to disposal conveyor
Inventor: PASSAVANT RUDOLF C DIPL ING
IPC: C02F11/123
Filed: 1973-11-09
Abstract: Material collected from the bar screen in the effluent channel of a sewage treatment plant can be dewatered as it is being scraped from the bar cleaning rake. Dewatering continues, by friction or by applied pressure, as the material moves towards the disposal conveyor. This saves the transport costs for the material to distant dewatering press or filter and the necessary intermediate bunkers. Savings accure both in capital costs and in power consumption.

Title: Automatic latch for seat belt roller - operates inside belt guide near passenger shoulder and applied by brake piston assembly
Inventor: WEMAN PER OLOF
IPC: B60R22/28
Filed: 1974-03-28
Abstract: The belt guide is strongly fixed to the car door jamb near the passenger's shoulder. The belt roller is positioned on the floor, and the belt rises between toothed jaws before passing over the guide toward the occupant. The belt is latched when the body of the guide turns about an axis to close the jaws and a prop is knocked away.
