Patent DE-3725143-A1 (DE)
Title: Device for delivering a predetermined volume of a pasty fluid
Inventor: TAGUCHI KATSUHIKO
IPC: B05C5/00
Filed: 1987-07-29
Abstract: A piston-drive device for delivering a predetermined small volume from a nozzle as a function of an electrical signal without a time delay is permitted by the slow rotation of a ball-screw shaft, the rotation being reduced by a differential gear system. A screw bush mounted on a ball-screw shaft moves a piston with very low speed, so that the exact delivery of a predetermined volume of a pasty fluid is possible. The vertical movement of the nozzle is compensated by a vertical movement of the piston-drive device in such a way that the relative position of the piston with respect to the nozzle remains unaltered.

Title: Multipole service apparatus (installation apparatus)
Inventor: RUNTSCH ERHARD ING GRAD
IPC: H02B1/06
Filed: 1987-09-04
Abstract: In the case of the subsequent assembly of individual cable protection components (12) and a fault-current component (residual current device) (10) to form a common service apparatus (30, 42) which is shaped as a block, the cable protection components (12) are connected to the associated switch poles (20, 22, 24) of the fault-current component (10) using open wiring, which is susceptible to interference from external influences. To this end, covers which are fitted for protection adversely affect access to the latching slides and thus adversely affect their operation. A protective cap (34) according to the invention is provided with retaining arms (36) which have at their one end latching tabs which engage in unlocking openings (10) of the latching slides (16) and are connected at their other end to spring supports (37) which are connected to the protective cap (34). A crossmember (38) which is rigidly connected to the retaining arms (36) makes it possible to operate the latching slides (16) simultaneously via the retaining arms (36), which are used as an extension. <IMAGE>

Title: Method for secondary treatment of thermally sprayed layers and inductor therefor
Inventor: STEINE HANS-THEO
IPC: C23C4/18
Filed: 1987-09-30
Abstract: A method for secondary treatment (after treatment) of layers which have been sprayed thermally onto a base material and consist of metal-based alloys is to be improved, especially in connection with an inductor and the applicability thereof. To this end, the layer is produced from an easily flowing (free-flowing) alloy - preferably on the basis of an Ni or Ni-Cr, containing B and Si - and the inductor for secondary treatment of the layer is excited with a controllable frequency in the range from 0.5 to 100 kHz, in particular from 1 to 70 kHz and an output of from 1 to 150 kW, preferably from 5 to 80 kW, the layer being fused in or sintered in at the surface of the workpiece, owing to the inductive heating, and the depth of penetration of the heating of the base material being controlled via the strength of the magnetic field and the size of the inductor or the rate of the relative movement between the latter and the layer to be treated.

Title: Radially acting safety friction clutch of a power tool
Inventor: HOYER RUDOLF ING GRAD
IPC: F16D7/10
Filed: 1988-03-05
Abstract: Safety clutches known in the case of power tools act axially and are equipped, for example, with compression or cup springs or are designed as friction clutches. In accordance with their axial mode of action, clutches of this type take up overall length and volume. The novel safety clutch is to make it possible to reduce the axial space requirement and likewise the constructional volume. The safety clutch is at least partly accommodated in a hollow space (40) of the body (39) of the drive gear (20) for the working spindle (13). Since the safety clutch can be accommodated inside a component which is present in any case, it contributes to the achievement of a short and compact and also economical design of a power tool. <IMAGE>

Patent DE-3829680-A1 (DE)
Title: Driver for a rope-pull window raiser
Inventor: MARSCHOLL KLAUS
IPC: E05F11/48
Filed: 1988-09-01
Abstract: What is described is a driver for a rope-pull window raiser, which is pulled up and down on a guide rail by means of a rope looped around a drive pulley. The driver is characterised in that it is subdivided into two parts which are displaceable relative to one another and to each of which one of the two rope ends is fastened. A directional stop mechanism is effective between the two parts, and a spring constantly presses the two parts in a rope-tautening direction. In special embodiments, means are provided for initially compensating a slight elongation of the rope, without the directional stop mechanism taking effect. This compensation can be cancelled again in the case of a downward movement of the driver on the guide rail. Only greater rope lengths are taken out of the drive system as a result of the function of the directional stop mechanism with a rope-tautening effect.

Title: Circuit arrangement to control the input of data units into a memory
Inventor: GOTTSMICH FRANZ
IPC: G06F13/16
Filed: 1988-12-23
Abstract: The data units, which are to be input into the memory (SP) and consist of a number of data subunits, are either taken entirely from only one selected source (ASP, CPU or SP), or taken combined from the data subunits of two sources, one of which is the memory (SP) itself, which must be read first. A register (e.g. MUX-L0A) with an integrated multiplexer for two input signals, which are formed from the data subunit (e.g. B0A) and a signal (0) which corresponds to the null unit, is assigned to each data subunit (e.g. B0A). Depending on the control signal (e.g. M, H/SELW0 or H/SEL0) which is fed to the register, one of the input signals is switched to the common output, and the outputs for mutually corresponding data subunits (e.g. B0A, B0C, B0S) of all sources (ASP, CPU, SP) are connected to the inputs of a common OR component (e.g. OR0), which is connected in series after them. Finally, the outputs (B0 to B7) of all OR components (OR0 to OR7) supply the data unit to be stored. <IMAGE>

Title: Transformer having windings composed of main conductors and additional conductors
Inventor: STEIN WERNER DR ING
IPC: H01F27/34
Filed: 1989-03-07
Abstract: In order to cope with reflections and resonances (caused by travelling waves at frequencies in the Megahertz band) in transformer windings, said reflections and resonances must be damped. For this purpose, it is known for an additional conductor (3) to be arranged physically parallel to a main conductor (1). According to the invention, the main conductor (1) has a thin additional conductor (3) composed of resistance material attached to its broad sides and/or an additional conductor (3) composed of resistance material is wound in, either bare or insulated, between two main conductors (1) which are joined to one another. According to the invention, windings made up of main conductors (1) and additional conductors (3) are expediently used in transformers having rated voltages of 245 kV or more. <IMAGE>
Patent DE-3907853-A1 (DE)
Inventor: GSCHLOESSL GEORG DIPL ING
IPC: H02P3/04
Filed: 1989-03-10
Abstract: The driving arrangement, which is suitable in particular for a lifting device, contains a reversible pole 3-phase motor which can be combined with a friction brake, that can be raised by an electromagnet (27), to form a structural unit. The two three-phase field windings, dimensioned for different numbers of poles, are connected in a star circuit and have star points (5, 9) which are led out at the motor terminal box (3) of the three-phase motor. The electromagnet (27) of the friction brake is connected to the star points (5, 9) via a rectifier circuit (29) and, when the three-phase motor is switched on, is energised by the differential voltage occurring in this case between the two star points (5, 9) in order to raise the friction brake. Together with a controllable switch (31), likewise connected to the two star points (5, 9), the rectifier circuit (29) is housed in the motor terminal box (3), the switching path (33) of the controllable switch short-circuiting or isolating the electromagnet (27) on the DC side when the three-phase motor is switched off. The friction brake of the driving arrangement can in this manner be controlled from a remotely located switch box, containing a directional contactor (15, 17) and a speed contactor (19), without any additional connecting lines being required for this purpose in addition to the connecting lines (9, 11) which are required in any case to operate the three-phase motor. In a corresponding manner, the arrangement is also suitable for three-phase motors connected in a delta circuit.
