Title: Pulse burst counter for operation over defined period - uses two counters, two shift registers three NAND=gates, and one AND=gate
Inventor: GRONEMEYER MICHAEL DIPL ING
IPC: H03K23/00
Filed: 1980-05-29
Abstract: The arrangement counts a train of pulses of a given width after a predetermined period of time using an M-stage shiftregister. The latter is controlled by the output from a clock pulse generator (T). The clock produces at least (M+1) pulses during the sampling time, where M is an integer. Gates (U1,U2,U3,U4) and a first counter (Z1) are combined to provide a feedback to the input of the shift register dependent on its output. The shift register output is also fed to a second counter (Z2) whose reset is controlled by the gates. The parallel outputs of the second counter are fed to a second register with a clock input controlled by the most significant bit of the first counter. The parallel outputs of this register may extend to further circuitry.

Patent DE-3109745-A1 (DE)
Title: Vector-wheel conveying system
Inventor: PUTZ ELMAR
IPC: F04D29/22
Filed: 1981-03-13
Abstract: Parallel ducts (7) are arranged in a plane, which are centered on the centre of rotation. In the central intake zone, the vector wheel is open on the suction side in the shape of a circle (22). The drive shaft is arranged externally in the centre of rotation and does not project into the suction chamber. When parallel ducts are employed, sectors remain (7) on the circle area which are closed to the medium to be conveyed (8, 9, 10). At their ends, the ducts are narrowed (20) in the manner of a mouthpiece, in order to ensure continuous flow within the ducts. The vector wheel is fitted into a conventional centrifugal-pump casing having an axial inlet. Additionally, the system is capable, by means of a combination of two vector wheels, to draw in a liquid without the casing first having been filled. Moreover, by fitting a second discharge port it is possible to build a separating pump. If used in motor vehicles, it can be employed both as a drive and to reduce the aerodynamic drag. <IMAGE>
Patent DE-3112146-A1 (DE)
Title: Coupling for fan roller
Inventor: RUDDIES REINHOLD
IPC: F04D29/26
Filed: 1981-03-27
Abstract: Applications of this type require a flexible coupling of small overall depth, high running accuracy even where the fan roller is mounted on one side, sufficient elasticity in order to compensate for misalignment, adjustment to the particular environmental conditions, for example high conveyed-medium temperatures or aggressive media. In the event of the drive motor being dismantled, rebalancing should not be necessary. The couplings known in practice for such applications meet these objects only to a very limited extent since, being made of elastic or thermoplastic material, they cannot be used at high temperatures or for larger drive outputs. Couplings wound from spring steel wire are too expensive and not suitable owing to their large overall depth. The object is met according to the invention in that the two halves of the coupling of non-ferrous metal or highly stable, heat-resistant thermoplastic are so designed (Fig. 1-6) that a standard commercial O-ring or alternatively one of Viton or comparable material assumes a shape approximating to a polygon, resulting in a high transmission torque with sufficient elasticity and good alignment. Rebalancing is not necessary in the event of dismantling. <IMAGE>

Title: Heat pump
Inventor: ZANDTNER RUDOLF
IPC: F25B47/00
Filed: 1981-07-17
Abstract: A heat pump is described, which comprises a compressor, a condenser, a throttling member and an evaporator flowed through by air. The expanded, evaporated, cold refrigerating medium flows through the pipeline of the evaporator. In addition, a further pipeline is arranged either in the evaporator or, in the flow direction of the air, in front of the evaporator, through which the still liquid and relatively warm pressurised refrigerating medium flows. As a result, the air is heated. The ice separation in the evaporator is thus prevented and the efficiency of the heat pump is increased.
Patent DE-3130081-A1 (DE)
Title: Running roller, in particular castor, for seating furniture
Inventor: SCHROEDER DIETER
IPC: B60B33/02
Filed: 1981-07-30
Abstract: The invention relates to a running roller which is designed in particular as a castor and is preferably intended for seating furniture. The aim of the invention is to make available a running roller, the wheel of which, when the seating furniture is subjected to load, is particularly reliably blocked against rotation, and is also suitable for hard, rough and uneven floors. This is achieved by virtue of the fact that the braking surface arranged on the wheel separately from the wheel running surface or the braking surface on the supporting part has a plurality of flat dogs arranged on a cylindrical surface, that there is formed on the supporting part or on the wheel at least one dog for engagement between two dogs arranged on the cylindrical surface, or at least one recess for receiving one of the flat dogs, and that the two flanks of a dog or a recess run essentially approximately parallel to one another and are aligned in engageable association with one another essentially approximately in the displacement direction of the supporting part. The result of this design is a "flat dog brake", which in particular has the advantage that it cannot be levered out even when relatively high roll-away forces are exerted on the seating furniture.
