Title: Device for switching an electric power tool equipped with a two-speed transmission from the first to the second transmission stage and vice versa
Inventor: GEIS WILHELM DIPL ING
IPC: B25F5/00
Filed: 1983-08-17
Abstract: Devices for switching an electric power tool equipped with a two-speed transmission from the first to the second transmission stage are known which contain a final control element actuable by way of a switch knob. This final control element is either a sliding linkage with a switch lever or an eccentric. It is the object of the invention to provide a switching device which takes up less space and is cheaper. This is achieved according to the invention by virtue of the fact that the final control element is designed as a rocker arm (28) which is arranged on a journal (27) positioned eccentrically with respect to the axis (26) of rotation of the switch knob (25), and that one end of the rocker arm is supported movably in the interior of the housing and its other end engages in a circumferential groove (22) of the gear wheel (20) arranged in axially displaceable fashion on the output shaft of the transmission. <IMAGE>

Title: Process for producing light-sensitive layers based on polyamides
Inventor: BRONSTERT BERND DR
IPC: G03F7/037
Filed: 1983-10-22
Abstract: In a process for producing light-sensitive polyamide layers which are suitable for producing photopolymeric printing forms or relief forms, a polyamide soluble or dispersible in the solvent, a photopolymerisable, low-molecular, ethylenically unsaturated compound, a photopolymerisation initiator and, if appropriate, further conventional additives are homogeneously mixed with one another, and the homogeneous mixture is, if necessary, freed of interfering volatile constituents by degassing and then formed to give the light-sensitive layer. According to the invention, the photopolymerisable mixture is, before forming to give the light-sensitive layer, heated largely with exclusion of oxygen and with simultaneous movement or further mixing in the melt for a period of 5 seconds to about 10 minutes to a temperature which is 20 to 80 DEG C above the softening point of the mixture.
Patent DE-3339422-A1 (DE)
Title: Curtain rod
Inventor: GILBERT PAUL
IPC: A47H7/02
Filed: 1983-10-29
Abstract: The object of the curtain rod up-and-down system is to allow it to move up and down vertically on the wall with any curtains from the floor at a convenient height via two hollow running rails with cable rollers at the top via a cable crank at the bottom with an up and down catch. Only one cable, which is of stainless special steel, runs over cable rollers down to the cable crank, selectively at the left or right. For double safety, a PVC strip is mounted on each runner, which strip also moves up and down in the hollow running rail. When the curtain rod is at the top, the PVC strip is fixed in the hollow running rail from the ground using an M6 knurled screw in each case. In the case of excessive ceiling heights or projecting window sills, the PVC strip must be used bent in four places so that it can bend on the floor or be guided over a projecting window sill. In the case of excessive width of curtain rods, one cable roller A4 is to be mounted centrally on the ceiling and one cable roller A4 is to be mounted offset in the curtain rod so that the curtain rod does not sag in the middle. The hollow running rails are attached to the wall only by Fischer plugs. When the curtain rod with all the curtains is at the top, the entire system is no longer visible due to the pelmet and overcurtains. The curtains can be attached to the curtain rod from the ground without the risk of accidents and moved up or down via the cable crank. <IMAGE>

Patent DE-3409249-A1 (DE)
Title: Thermoplastics container and process for the production thereof
Inventor: HAGNER HANS
IPC: B29C63/38
Filed: 1984-03-14
Abstract: A thermoplastics container is designed in a frustoconical shape in its lower region with a conicity of any desired shallowness. In its upper region it has a stacking rim having a constant cross-section for almost its entire height. The upper edge of the stacking rim and the transition region to the conical lower part of the circumferential surface of the container are each constricted, on the one hand producing a good stability of the stacking rim and on the other hand producing a defined stop edge when a plurality of containers are stacked into one another. In order to produce containers of this kind, advantageously a process is used in which the outer shape of the container is produced in that stretched plastics material is shrunk onto a mould core defining the shape of the container with the application of heat. Virtually any desired container shape can be produced in this manner. The container base can be already integrated in the shrinking process or, however, subsequently using known processes, adhesively bonded into the circumferential surface of the container or welded thereto. The process can be readily automated using conventional control and handling means.

Title: Disconnectable trailer coupling for motor vehicles
Inventor: JUERGENS WALTER DR ING
IPC: B60D1/52
Filed: 1984-06-07
Abstract: The invention relates to a disconnectable trailer coupling in which the ball-ended rod of the coupling strikes against a lock when it is inserted and as a result triggers an element which engages in the recess in the ball-ended rod and thus brings about locking between the basic body of the trailer coupling attached to the motor vehicle and the ball-ended rod. In one embodiment, the position of the fixing element is secured with respect to the basic body of the coupling in the mounted position of the ball-ended rod by means of a further lock which is activated after the engagement and coupling of the basic body to the ball-ended rod.

Title: Laser radiation-resistant absorption-free oxidic film-optical component and process for its production
Inventor: BERNITZKI HELMUT
IPC: G02B1/10
Filed: 1984-08-20
Abstract: The invention relates to a laser radiation-resistant absorption-free oxidic film-optical component and a process for its production. The invention can be used in the construction of optical equipment, in microelectronics, optoelectronics and in the field of integrated optics. The process can be employed for producing such components in all known vacuum-coating plants. The aim of the invention is to provide an absorption-free optical thin-film component with high laser radiation resistance and to specify an economical production process for such components. The object arising from this is to find possible ways of directly increasing the laser radiation resistance of the individual films themselves even during their preparation process. The object is achieved by a laser radiation-resistant absorption-free optical thin-film component in which the oxygen content of the films is at least 2% greater than is necessary to maintain complete stoichiometry. The process for producing such components is characterised by the selection and corresponding variation of process parameters during the vacuum-coating process, so that an additional incorporation in the film of more than 2% of oxygen that is necessary for complete stoichiometry is ensured.

Title: Switch circuit-breaker unit
Inventor: BRUCHMANN KLAUS
IPC: H01H85/24
Filed: 1984-02-24
Abstract: A switch circuit-breaker unit (1) consists of a housing (2) in which two housing switching contacts (60, 61) are connected to an input power connection (48) and to an output power connection (49). A switching rocker (12) can be pivoted in the housing between a switched-off position and a switched-on position. A circuit-breaker plunger (18) is arranged in the switching rocker (12). A circuit-breaker insert (75) electrically connects the housing switching contacts (60, 61). Two switching contacts (70, 71) of the circuit-breaker plunger (18) make contact with two contact caps of the circuit-breaker insert (75) and with the two housing switching contacts (60, 61), in the switched-on position of the switching rocker (12). The switch circuit-breaker unit can thus be specified for a large number of different rated-current steps (including in particular relatively high rated-current steps), and is suitable for circuit-breaker inserts for a wide variety of circuit-breaker systems. The apparatus improves the electrical contact and the heat dissipation. Both the mechanical and the electrical switching work between the switching contacts of the circuit-breaker plunger and the housing switching contacts ensure that the contact caps of the circuit-breaker insert are protected against mechanical wear and spark erosion. Arc formation is precluded and a low contact resistance is ensured. If the switching contact of the circuit-breaker plunger is eroded, it can easily be replaced, so that permanently installed parts of the switch circuit-breaker unit do not need to be removed.
