Title: Double supply circuit with single low current regulator - has by=pass transistor supplying high currents when required
Inventor: MEYER DIETER
IPC: G05F1/577
Filed: 1980-09-11
Abstract: A double voltage supply unit with regulator requires only a single regulator (2) which takes only a low current, resulting in a lower cost and increased reliability. A resistor (1) is connected in front of the voltage regulator and in parallel with the base-emitter path of a transistor (6). The collector-emitter path of a further transistor (8) is connected between the collector of the first transistor and the output of the voltage regulator (2). The further transistor is driven from a voltage source via a buffer stage (11) and provides high current when required. The inputs to the circuit contain diodes (10) connected to the forward conducting direction. This prevents the destruction of the circuit components being caused by connecting with incorrect polarity. The arrangement is suitable for all applications requiring a low standby current and large operating current, e.g. for vehicle computers.

Title: Inlet/exhaust control for internal combustion engines
Inventor: VIRGILIO GUSTAV
IPC: F01L5/08
Filed: 1981-04-22
Abstract: An inlet/exhaust control for internal combustion engines is proposed in which control slide valves (3, 4) are used for optimum control of the inlet and exhaust opening times for the working cylinder (2). For this purpose an additional movement by means of an auxiliary drive (43) is superimposed on the crankshaft-dependent movement of the control slide valves (3, 4). Correspondingly angled control edges (5, 6) and/or apertures (7, 8) are assigned to air inlet and exhaust ports (9, 10) arranged slanting in the working cylinder (2). A shifting of the opening and closing times for the inlet and the exhaust port (9, 10) is achieved by rotation of the cylinder sleeves (3, 4). The rotary control of the cylinder sleeves (3, 4) is provided by an electronic control unit (46), which, supplied with engine speed data and load data, undertakes the adjustment of the cylinder sleeves (3, 4) according to a set of engine performance characteristics fed into it. <IMAGE>

Title: Ball-and-socket joint for a walking aid, especially a crutch, cane or the like
Inventor: LOTTNER JOSEF
IPC: A61H3/02
Filed: 1981-05-05
Abstract: In an antislip element with ball-and-socket joint, the invention solves the problem of creating a stable and durable connection between the ring (11) and the walking surface support (30). For this purpose, it is provided that the marginal flange (34) of the ring (11) be designed on the outer wall (32) of a peripheral groove (31) in the bottom of the ring (11) and face the opposite inner wall (33) and that a hollow attachment (35), profiled so as to be adapted to the outer circumference, of the walking surface support (30) lockingly engages in the groove (31). As a result of this, the attachment (35) of the walking surface support (30) serving as a connecting element is supported on the inside by the inner wall (33) and on the outside by the outer wall (32) of the groove (31) of the ring (11). In this way the attachment (35) is protected, accommodated in the ring (11) and secured against detachment. The attachment (35) has an outwardly directed edge part (37) and a section (38) offset with respect to this, and the outer circumference of the edge part is smaller than the outer circumference of the walking surface support (30). The ring (11) and the walking surface support (30) can therefore have the same outer diameter, and the outer surfaces of the ring (11) and of the walking surface support (30) assembled with the latter merge into one another without a shoulder. <IMAGE>

Title: Transistor ballast apparatus
Inventor: MANCHEN JOACHIM DIPL ING
IPC: H02M7/5383
Filed: 1981-10-08
Abstract: For a transistor ballast apparatus for supplying fluorescent lamps from DC networks, especially fluctuating on-board networks having a push-pull invertor, whose transformer has a tapped primary winding and a plurality of secondary windings for preheating, operating voltage and auxiliary starting voltage, the complex object exists of being able to produce said apparatus smaller and at less cost with increased efficiency and universal applicability. The circuit is intended to be able to be designed and adapted in a clear manner. As the solution, the invention proposes that the operating frequency of the invertor be selected to be higher than 20 kHz, preferably between 20 and 40 kHz, and be maintained approximately linearly depending on the fluctuations of the input voltage (UE), and that, via the frequency change, the lamp current be kept constant by means of a selected series-resonant circuit (31, 23) located in the secondary operating circuit of the invertor-transformer (5), a straight-line part of the resonance curve being used for the operating region. In this case, the fluctuations in the input voltage (UE) are intended to be converted into a frequency change of the invertor via a switching regulator (8) which externally controls the invertor transistors (6, 7). <IMAGE>

Title: Recombinator with drying agent
Inventor: LEDJEFF KONSTANTIN DIPL PHYS D
IPC: H01M10/52
Filed: 1982-01-21
Abstract: Recombinators for the catalytic combustion of hydrogen and oxygen, such as are used especially in electrical accumulators, remain active for a longer time if the catalyst (1) is protected by a drying agent (2), arranged close thereto, for example silica gel, from humidification due to recombination water condensing out. The catalyst and drying agent are here expediently formed as foils or mats. In enclosed spaces of low humidity (battery spaces, EDP installations), the drying agent can also be located at a greater distance from the catalyst, since it then indirectly dries the latter by setting a steep gradient of the water vapour partial pressure. <IMAGE>
