Patent DE-3207429-A1 (DE)
Title: Improved evaporator
Inventor: LAUDE FRITZ
IPC: F28F13/02
Filed: 1982-03-02
Abstract: The problem of the circulation of heat pumps is that the efficiency of the required heat exchangers, such as evaporators, is very low. By using metal balls, the heat transfer can however be substantially improved without the flow resistance being increased, something which is not possible using vanes. It is also possible in this way to assemble a row of condensers in an evaporator, something which is required for the application of the heating tubes.

Title: Luminous element for images which can be transilluminated, such as film viewers
Inventor: KARL GERHARD DIPL PHYS
IPC: G02B6/00
Filed: 1982-06-25
Abstract: In an illuminating element for images that can be transilluminated, such as in a film viewer, use is made of a luminous surface for bearing the mounted image, which surface is irradiated at the rear by light sources. It is proposed for the purpose of space-saving and economic construction to arrange below a diffusing layer which serves as illuminating surface the top side, provided with surface structures for sporadic refraction of light, of a light-conducting plate whose rear carries a reflection layer. The plate narrow side serves as a light entry port for light sources arranged at the edge of the plate.
Patent DE-3227392-A1 (DE)
Title: Adaptive current regulator
Inventor: BERGMANN LUTZ DIPL ING
IPC: H02M7/757
Filed: 1982-07-22
Abstract: In this adaptive current regulator (1 + 2 + 4 + 5) for a current regulating loop, having a converter as actuating element and a resistive-inductive load as the control path, the desired current value (Ides) is supplied on the one hand to a PI current regulator (1) having a regulating amplifier (O1) and on the other hand via a matching amplifier/low-path filter (4) to a function transmitter (5). The regulator output voltage (y) of the PI current regulator (1), and the output voltage (Ua) of the function transmitter (5) are added. The sum signal thus formed is supplied as a control voltage (S) to triggering equipment (3) of a converter (SR) for generating triggering pulses (Z). The output voltage (Ua) of the function transmitter (5) has the value zero in the case of a current without gaps and on the gap boundary (LG), and is increased in the current region having gaps, with a reduced desired current value (Ides). In this way, a good dynamic response to current with gaps is ensured for current regulating loops with converters. One field of application is for converters which are connected to a three-phase voltage network for supplying DC motors. <IMAGE>

Title: Heat exchanger, in particular space heater, and method for producing its distributing manifold
Inventor: PENKERT RICHARD DIPL ING
IPC: F28F9/18
Filed: 1982-08-10
Abstract: The invention relates to a heat exchanger, in particular space heater, having at least one distributing manifold and having finned heat exchange tubes. The latter are in each case connected next to one another to a cross-sectional surface on branches of the distributing manifold which open out on the side of the circumference. The heat exchange tube has a guide tube for a heat exchange fluid and a thermally conductive finning of the guide tube in the form of webs which form a front plate, extending along the one side of the guide tube, as well as a web arrangement which has a central web, extending outwards from the guide tube and running at a right angle to the front plate, and at least one intermediate web which proceeds from the guide tube transversely to the central web. In this arrangement, a connection, in particular a welded connection, is formed between a fin of the respective heat exchange tube and a projecting continuation of the distributing manifold which extends along the distributing manifold. At least one intermediate web of the respective heat exchange tube extends parallel to the continuation while overlapping the same. According to the invention, the signal arrangement is open towards the side of the guide tube opposite the front plate, and a connection of the continuation (50) is provided to an intermediate web (28) of the respective heat exchange tube. The connection is preferably constructed as a riveted connection or welded point (54). When the distributing manifold of the heat exchanger is constructed by extrusion in conjunction with the integral formation of a continuation extending unbroken along the distributing manifold, only a single continuation is preferably provided according to the invention, and said continuation is at least partially abraded at least in the region of the cross-sectional surface of the heat exchange tubes that is to be connected. <IMAGE>

Title: Oscillator with H101 cavity resonator and method for manufacturing it
Inventor: RUST STEPHAN DIPL ING
IPC: H03B9/14
Filed: 1982-11-19
Abstract: An oscillator with H101 cavity resonator (1) with a two-pole resonant element (3) which is arranged in the plane of one cavity wall (2). To improve the unloaded Q and achieve low production complexity, it is proposed to coat the entire cavity wall currentlessly with gold or silver and to make it gapless with the exception of two penetrations (4, 9), one of which (9) is provided for coupling-out whilst the second one (4) is located at the resonant element (3) in the said cavity wall (2). The penetrations are dimensioned in such a manner that, on the one hand, currentless coating of the cavity wall is possible and, on the other hand, only an evanescent mode wave can propagate in the penetrations (4, 9). <IMAGE>

Title: Electric motor with an automatically acting brake
Inventor: ZELLE EDGAR
IPC: H02K7/102
Filed: 1984-03-02
Abstract: The invention relates to an electric motor with a brake which acts automatically when the motor is switched off and has a ferromagnetic armature which surrounds the motor shaft between the rotor laminate stack and the bearing plate and can be attracted to the rotor by the magnetic flux of the motor penetrating into the rotor, axially against a spring force, the armature being mounted directly on a braking element, which is guided axially on the shaft, can rotate with the rotor and can be pressed against a fixed-position braking element, and the rotatable braking element being rotatable through a rotation angle, limited by stops, with respect to the rotor and having first wedge surfaces which are inclined with respect to the rotation plane and, on engagement of the brake, rest on associated, inclined second wedge surfaces of the rotor, by means of which surfaces a stop is formed. The invention is based on the object of designing this arrangement in such a manner that high braking torques are possible with little complexity, without there being any risk of blocking or sticking of the brake. This is achieved in that the material of the one wedge surface is significantly softer than that of the other wedge surface.

Title: Cylinder lock
Inventor: BUHL JOACHIM
IPC: E05B67/24
Filed: 1984-06-12
Abstract: A cylinder lock comprises a cylinder housing, a cylinder mounted rotatably therein, a plurality of blocking discs mounted rotatably to a limited extent in the cylinder and rotatable by means of a key, a plurality of spring discs arranged non-rotatably between the blocking discs, and a blocking rod which can lock the cylinder relative to the cylinder housing and which, in the blocking position, engages both into a groove of a cylinder and into a groove of the cylinder housing. Furthermore, within the cylinder is provided a longitudinally extending rib which limits the rotational movability of the spring discs and blocking discs. In order to achieve a greater security of position than hitherto for the blocking discs (12) which are in the blocking position, in the blocking position of the lock all the blocking discs (12) are secured releasably against unintentional rotation by means of radially effective resilient catch elements (32, 32') held on the cylinder (11) and engaging on the circumference of the blocking discs. <IMAGE>
