Title: Reducing from boat with cycloidal propellers - involves releasing curtain of air bubbles from upstream over propeller baseplate
Inventor: LAUCKS RUDOLF
IPC: B63G7/00
Filed: 1980-12-11
Abstract: The procedure for reducing noise-emission from watercraft, partic. research- and mine counter-measure vessels, applies to craft with cycloidal propellers in the hull bottom. It involves passing a curtain of air, discharged through the hull under control as appropriate upstream of the runner, over the runner baseplate (10,10') which substantially forms the propeller casing waterside closure. Air ducts (4) are arranged adjoining the hull plating around at least a sector of the baseplate circumference. They have multiple small outlet openings, pref. terminating level with the plating outer surface.

Title: Combustion heater for caravans etc. - has heat exchanger with duct with increased cross-sectional area to increase heat transfer
Inventor: KREIS PHILIPP
IPC: F24C3/00
Filed: 1980-08-07
Abstract: The combustion heater can use either gaseous or vaporised liquid fuel. The combustion gases pass through a heat exchanger consisting of a vertical duct (3) which runs into a horizontal duct (4). The gas flow is then turned through 180 deg. in a duct (6) which directs it into a lower horizontal duct (8) before reaching the outlet (30) through an adjacent duct (9). The cross-sectional area of the lower horizontal duct is considerably greater than that of the other ducts so that the surface area of this duct is correspondingly increased. Also the greater cross-sectional area results in a lower gas velocity so that the time taken to pass through the duct is increased. These two factors increase the heat transfer from the combustion gases to the externally circulating air.
Patent DE-3103424-A1 (DE)
Title: Bathing support
Inventor: HORANEK GEB SVOBODA
IPC: A47K3/12
Filed: 1981-02-02
Abstract: This is a support for insertion in the bath tub. The slope of the support guarantees the position of the bathing body below the bathing water level and of the head above this level. Slipping of the body in the bath is avoided by the double-trough shape of the support. This invention is important for bathing elderly or disabled individuals, but especially for small children, support of whom in the bath tub is very tiring for the individual bathing them and may easily lead to the child having an accident due to unexpected reflex movements or in moments of inattentiveness.
Patent DE-3105213-A1 (DE)
Title: Ski overrun preventer
Inventor: KUEMMEL KARL-WILHELM
IPC: A63C5/06
Filed: 1981-02-13
Abstract: The invention relates to a ski overrun preventer which can be integrated into or retrofitted to the ends of the skis. The intention behind such a ski overrun preventer is to ensure that following skiers can not overrun the ends of the leader's skis and damage the ends of his skis. This loutish behaviour is found to an increasing extent when queuing for ski lifts. Devices of this kind are hitherto unknown on skis. The object of the invention is to keep other skiers away from the ends of ones own skis by an arrangement whereby, in the event of overrunning, the slip coating of the overrunning ski is damaged by the ski overrun preventer. This object is achieved, according to the invention, in that a metal plate (ski overrun preventer) is affixed to the end of each ski, having sharp and directionally oriented scraper projections (1). If the following skier now overruns the ends of the skis (and hence the ski overrun preventer), grooves are cut in the slip coating of the overrunning skis by the scraper humps. <IMAGE>

Patent DE-3111834-A1 (DE)
Title: Screw compressor
Inventor: KIRSTEN GUENTER
IPC: F04C29/00
Filed: 1981-03-26
Abstract: The invention relates to a screw compressor, whose rotors, owing to the pressure differential between the discharge side and the intake side, are subject in each case to axial thrust. In order to relieve the axial bearings required therefor, oil under pressure is supplied into an annular cavity and a relief force is generated via an end face allocated to the shaft journal. The axial bearing is thus relieved, and in addition adequate lubrication of the bearings is achieved owing to the oil under pressure escaping from said annular cavity. Advantageously, the bearing cavity is sealed by means of a cover, so that, in conjunction with a suitable discharge line, a defined lubricant throughput through the bearing is ensured. Furthermore, said bearing cavity is fed with the leakage oil/gas mixture of a separator, in order to improve the efficiency or to increase the absorbing volume of the screw compressor. <IMAGE>
Patent DE-3112377-A1 (DE)
Title: Flyback converter switched-mode power supply having an expanded control range
Inventor: SIESTRUP FRIEDRICH
IPC: H02M3/335
Filed: 1981-03-28
Abstract: The control range of a flyback converter switched-mode power supply is limited, inter alia, by the limiting resistor in the base circuit, which limiting resistor is provided to protect the power switching transistor, since the control current which is required for full switching-through is no longer reached when the supply voltage is below a specific threshold. According to the teaching of the invention, a significant expansion of the control range is achieved in such a manner that a constant-current source is connected in the base circuit of the power switching transistor instead of a fixed current-limiting resistor. The power switching transistor thus remains completely switched through, even at a very low supply voltage, down to the residual voltage of the constant-current source, which is in general designed as a transistor, that is to say down to a voltage drop of only a few tenths of a volt. At the same time, there is no risk whatsoever of current overloading in the base circuit at a very high supply voltage, because the constant-current source limits the control current even better than the otherwise normal fixed resistor.
Patent DE-3118270-A1 (DE)
Title: Toy clock
Inventor: KIRCHHOF HELMUT
IPC: G09B19/12
Filed: 1981-05-08
Abstract: A toy clock has a clock mechanism with hands, but a plurality of insertable templates with different time symbols are employed instead of a fixed dial. The torque transmission from the clock mechanism to the clock hands takes place via two-part clock-hand shafts which are releasably connected to each other. By interchanging various templates and removing the clock hand, various speed levels can be achieved which are appropriate to the age of the child. A particular, advantageous embodiment provides for a plurality of puzzle pieces to be used under the insertable templates, the themes of which can visually supplement the time symbols provided on the templates. As a result, both the playing value of the toy clock and the educational effect are enhanced.

Patent DE-3135697-A1 (DE)
Title: Variable-delivery vane pump
Inventor: MERZ JOHANN ING GRAD
IPC: F04C14/22
Filed: 1981-09-09
Abstract: A variable-delivery vane pump has a cam ring (4) which can be adjusted about a pivot (6). The cam ring (4) is actuated on one side by the outlet pressure and on the other side by the inlet pressure and a restoring spring (2). The force resulting from the outlet-side differential pressure acts as an adjusting force (P) against the force of the spring. As the restoring spring (21) is fitted obliquely with respect to the counteracting hydraulic adjusting force (P) and to a plane (A) arranged perpendicularly through the axis of the shaft (2), its biasing force (pretensioning force) increases only slightly as the compression increases. The pump therefore operates with a small regulating range. <IMAGE>

Title: Drive for rolling doors
Inventor: PETERS MANFRED-JOSEF DIPL ING
IPC: E06B9/76
Filed: 1982-01-21
Abstract: The invention relates to a drive for rolling doors or the like, with a box-shaped flat housing for the gear mechanism. Coupled to the motor shaft is a plug-in coupling passed out of the housing, for the direct connection of a hand crank of an emergency rod mechanism. The hollow drive shaft driven by the motor via a reduction gear mechanism is arranged eccentrically in the housing and extends through the entire housing, allowing the gear mechanism to be attached to the axle of the rolling door at the right or at the left. In this eccentric arrangement of the drive shaft, the control box is arranged on the side opposite the motor, relative to the hollow drive shaft, and parallel to the motor axis, while its cover covers the associated narrow side of the housing. This results in a compact design which also makes it possible to support the shafts of the gear mechanisms at two points in the walls of the housing. <IMAGE>
