Title: Drive circuit for toy vehicles on model race course - provides multivibrator-controlled quasi-erratic speed changes to form obstacle to competitors
Inventor: NEUHIERL HERMANN DR
IPC: A63H18/16
Filed: 1979-09-03
Abstract: A circuit supplying a.c. via rails (8,9) comprises an oscillator (19) and a current regulating transistor (13) which, in turn, is controlled by a multivibrator (10) and a manual resistance regulator (14), variable resistor (11) for changing the multi-vibrator period, and a variable resistor (17) for changing the degree of abruptness. The transistor (13) causes current changes to alter the speed of the toy vehicles. The larger the capacitor (20) to be charged or discharged through resistor (17), the more gradual the changes conditioned by the state changes of the multivibrator, or of transistor (12) respectively. By changing the rhythm of the speed changes and the degree of abruptness of gradualness of these changes the element of surprise is increased for the players whose model cars must be so controlled as to avoid the 'obstacle vehicles' on the track.

Title: Collapsible easily transportable cradle frame with runners - has inclined slits on top to take bolts of baby carriage or seat
Inventor: HOFMANN MANFRED
IPC: A47D9/00
Filed: 1979-10-11
Abstract: The two rocker runners (1) are each provided in their upper areas above the actual runner (10) with inclined slits (21) which are open at the top and are inclined to the horizontal. The spacing of the slits in the two horizontal axes corresponds to the same spacing of bolts (B) provided in the seat frame of a baby carriage or the like so that the seat can be detachably connected to the chassis by means of the bolts (B) on the frame. The pram or carrycot can now be converted to a cradle without disturbing the baby. To prevent accidental removal or release of the bolt from the slits a locking lever (22) can be mounted on at least one of the slots to close the opening.

Title: Low pressure mercury vapour discharge lamp making machine - uses radiation reflected by droplet to determine quantity of mercury dispensed
Inventor: MORASS WALTER DR
IPC: H01J9/42
Filed: 1979-11-07
Abstract: The machine for making low pressure mercury vapour discharge lamps, has a station at which the quantity of mercury for each lamp is determined. The lamps are carried vertically past the dispensing position by a turntable along a circular path (U). In line with the vertical axis of the tube is a vertical glass tube (2) forming a dispensing pump. A beam of radiation (11) form a laser (8) is directed onto the droplet (3) of mercury inside the pump tube. The amount of radiation reflected from the curved surface of the mercury droplet, depends on the size and surface area of the droplet. This is measured by an optical measuring device (9) with its axis at right angles to the axis of the laser beam.

Title: Hybrid associative memory for sorting stored data - has extra storage unit permitting house-keeping operations
Inventor: WOLF GERHARD
IPC: G11C15/00
Filed: 1980-03-11
Abstract: The memory consists of an associative matrix with numerous fields and a non-associative memory with numerous storage units. The storage units are composed of storage sections corresponding to the associative fields of the matrix such that any one storage section from each storage unit correspond to one another and to the same associative field of the matrix. The contents of each storage section can be transferred to the associated associative field in the matrix. Apart from the storage units for storing general data from files or tables in the base memory at least one additional storage unit is provided to store data and information for simplifying or permitting the utilisation of existing associative surfaces for work processes of the hybrid associative memory. The advantage lies in reducing the number of additional devices needed for monitoring and controlling the degree of filling and for managing lists of parameters and controlling work processes like finding and sorting data.

Title: Fast acting water heater - has vertical tube with burner at top, directly heating falling water film covering inside surface
IPC: F24H1/18
Filed: 1980-06-18
Abstract: The direct water heater has a burner (6) brought into direct contact with the water to be heated, for e.g. small swimming pools. Between a water filled tank (10) and an overhead reservoir (2) is a vertical tube (3) with a funnel-shaped top (4). Water, pumped from the tank to the reservoir, overflows the rim of the funnel and trickles down the inside of the tube, covering its inside surface with a water film (5). The combustion gases are in direct contact with this film, heating it rapidly, and the exhaust gases are discharged through an outlet (8) at the top of the tank. Baffles (14) are included inside the bottom of the tube, producing a swirling action to improve the heating effect. A flange may be incorporated at the bottom of the tube, projecting inwards to discharge the flow from its centre.

Title: Speed variation of asynchronous motor direct connected to generator - by changing generator speed whilst maintaining constant voltage to frequency ratios
Inventor: GROSER HEINZ ING GRAD
IPC: B60L50/13
Filed: 1980-12-06
Abstract: The application of the control system is to drives in places where space is limited, for example in mining, and typically for traction duty. The motors (6) are directly coupled to a generator driven by a prime move (1), for example a diesel engine. A speed regulator (7) can be set to give the generator frequency for the required motor speed. This regulator (7) is linked to a subordinate voltage regulator (4) which varies the generator excitation to maintain a constant output voltage to frequency ratio. To obtain the best performance from the engine (1) it is desirable to run it at constant speed, and to obtain the desired generator speed by use of a variable ratio gear (2). The proposed control system eliminates the need for a bulky static converter.

Patent DE-3105431-A1 (DE)
Title: Pressure regulating valve for hydraulic pressure media with compensation of temperature influences, especially for the control of automatic gearboxes
Inventor: ELTZE GEORG DIPL ING
IPC: G05D16/16
Filed: 1981-02-14
Abstract: The general area of application of the invention is that of control and regulating valves exposed to varying operating temperatures in which the shear modulus of the regulating spring becomes smaller and the set value for the output pressure is thus falsified as the temperature rises. The object is to reduce the constructional outlay for the means for compensating temperature influences comprising a pair of materials with different coefficients of thermal expansion. A thrust piece with a high coefficient of thermal expansion inserted between the control slide and the regulating spring compensates by its axial thermal expansion for the shortening of the spring required to maintain the spring loading associated with the set value in the case of a smaller shear modulus.
