Inventor: WEISS ECKHARD
IPC: F01L13/06
Filed: 1989-10-10
Abstract: In a four-stroke internal-combustion engine, in particular for driving a motor vehicle, having gas exchange valves and an additional outlet valve for each cylinder, said outlet valve being adjustable by an actuating device, and having a throttle valve which is arranged in the outlet passage of the internal-combustion engine and is adjustable by an actuating device, the actuating devices being actuable by at least one directional control valve adjustable in dependence on a brake switch and braking of the internal-combustion engine being accomplished by opening the additional outlet valves and throttling the exhaust gases during the braking procedure, the braking of the internal-combustion engine is speed-dependent in that engine braking is cancelled below a limiting speed.

IPC: H01H36/00
Filed: 1989-10-26
Abstract: There are various fields of application in motor vehicles for mechanically operated switches which must be absolutely sealed against the ingress of gases and liquids. Normally, a release part, which is not part of the actual switch, initiates the intended switching function via a transmission element, which is part of the switch, such as a ram, pin, lever or the like. In consequence, sealing difficulties can arise, especially in the case of significant temperature influences, which can be avoided in a simple manner by the moving parts of the switch (1) and the fixed contacts (5) being arranged hermetically sealed in a switch housing (2) which is closed on all sides and by the contact carrier (6) being connected to an armature, which can be operated in a contact-free manner by magnetic force from the outside of the switch housing (2), by means of the release part (11), which armature is acted on in its quiescent position by a compression spring (10) that is expediently arranged in the switch housing (2) between the armature (9) and the release part (11). In this way, in addition to completely wear-free indirect operation of the switch by the release part (11), reliable sealing of all moving switch parts can be achieved in a particularly simple manner in all operating conditions that may arise. <IMAGE>

Abstract: A retractable barrier device comprises a reel assembly including a spindle rotatable within a cylindrical housing and a flexible elongate barrier element (16), secured at one end to the spindle so as to be wound on the spindle by rotation of the spindle by a spring, which is tensioned as the element is withdrawn from the spindle. There is attached to the free end of the flexible element a magnetic assembly (17) comprising a permanent magnet (28) within a housing (21), for engagement with a suitable metal keeper spaced from the reel assembly. The magnetic assembly (17) includes a part-cylindrical concavely curved surface (25) so disposed that the magnet (28) will hold the assembly in magnetic engagement with a part-­cylindrical convexly curved metal surface (26) when the concave surface (25) on the assembly (17) is brought into registering engagement with the convex surface (26).

Abstract: The nut (1) and the counternut (2) have, respectively, a cylindrical bearing surface (3) and a cylindrical hollow (4) which interact with one another and the axis (9) of which is eccentric relative to that (8) of the internal screw thread. Locking is achieved by holding the nut (1) in position and by simultaneous rotation of the counternut (2), this causing the play (10), on two opposing surfaces, to be taken up, which creates a shearing stress locking the two elements (1, 2) on a threaded rod (11), for example. In a locked position, a play (7) remains, preventing the appearance of an axial stress in the threaded rod (11). <IMAGE>

Abstract: A regenerative rotodynamic compressor has a stator which 
defines, together with the periphery of an impeller, an annular flow 
channel of circular cross-section within which is a core ring having 
a circular cross-section coaxial with and of a diameter at least half 
the diameter of the flow channel cross-section. The impeller has a 
ring of curve aerodynamic blades around its periphery that project 
laterally into the flow channel up to the core ring. The stator, the 
impeller and blading, and the core ring are all made as die-cast 
components, the stator being divided on a stepped radial plane so 
as to the assemblable from two main die-cast components and an 
insert ring, also die-cast, that in part defines the flow channel and is 
fitted between the two main components, being secured to one of 
them. Inwardly directed radial pegs on the core ring locate it in the 
flow channel by being clamped between the insert ring and the 
main stator component to which it is secured. Inlet and outlet baf­
fles on the core ring extend into the inlet and outlet ports respec­
tively, to guide fluid into and out of the machine with greater effi­
ciency.

Abstract: La présente invention décrit un amplificateur réparti modifié qui est susceptible d'assurer un fonctionnement en push-pull sans présenter les pertes de charge de la combinaison push-pull classique. Ledit amplificateur possède une configuration d'amplificateur réparti et des moyens d'inversion de signaux, tels qu'un transformateur de sortie (32, 38) à transmission à large bande passante, interconnectés dans les lignes d'entrée (24) et de sortie (26). Ces moyens d'inversion de signaux sont placés de la manière la plus efficace au niveau des centres électriques des lignes, mais peuvent être placés à n'importe quel endroit des différentes lignes afin de donner des performances optimales pour des applications spécifiques. Les segments distincts de l'amplificateur réparti séparés par les moyens d'inversion de signaux fonctionnent en opposition de phase, mais les signaux envoyés à la charge (14) s'ajoutent en phase, assurant ainsi un fonctionnement en push-ull. Une seule résistance terminale en état inverse (44) étant nécessaire, la puissance normalement perdue en raison du chargement par l'amplificateur annexe d'un système amplificateur réparti à combinaison push-pull classique est délivrée à la place à la charge de sortie (14).

Abstract: With the aid of solar energy in a closed system comprising, for example, a greenhouse (1) and a more elevated part (4), moist and warm air (1O) is produced from open water vessels (2). In the more elevated part (4), this air gives up its heat to the surrounding air (6), which leads to water condensing out. The transport of the internal moist air is carried out by means of temperature-dependent circulation due to gravity. By means of a chimney-like jacketing, open at the bottom and top, applied to the condenser part, a gravity-induced updraft can increase the transport of the heat of condensation to the surrounding air, which leads to a greater efficiency of distillation. The process only requires external energy for filling the liquid vessels and is otherwise self-regulating.

Abstract: An enable circuit that integrates thermal shutdown capability. The enable circuit utilizes a temperature insensitive threshold detector network that provides a desired biasing current when the ON/OFF signal applied at its input exceeds a preselected voltage. Thermally sensitive circuitry connected between the input of the threshold detector network and ground remains off when the ON/OFF signal is equal to the preselected voltage and the temperature of the enable circuit is below a preselected maximum temperature. However, when the temperature of the enable circuit reaches the preselected maximum temperature, the thermally sensitive circuitry turns on, clamping the input signal to the threshold detector network below the preselected voltage.
