Title: Device for permanent coupling of a light source with an optical waveguide
Inventor: AGUILAR ANTONIO MORALES
IPC: G02B6/42
Filed: 1983-01-21
Abstract: The device involves an encapsulated design which essentially comprises a carrier part having the light source (C), a fibre holder (A) containing the glued-in optical waveguide and a covering cap (B) which encloses the arrangement. The optical fibre fed in through the reversed sleeve-shaped part of the fibre holder (A) lies with its front end, from which the covering (7) has been stripped, in a slot (2) of the fibre holder (A) whose front has a semi-cylindrical shape. In front of the fibre end, the fibre holder (A) has a recess (1) for the carrier of the light source (C) to whose external shape (8) the recess (1) is adapted with a slightly larger dimension. This creates clearance for the alignment of the optical elements on top of one another. Before the adjustment, which is carried out in a conventional manner, the cavity is filled with a setting adhesive which sets after the adjustment and permanently bonds both parts to each other over a large area. <IMAGE>

Patent DE-3329790-A1 (DE)
Title: Valve support for piston compressors
Inventor: SCHLOSSARCZYK HEINRICH
IPC: F04B49/24
Filed: 1983-08-18
Abstract: A known method of controlling the throughput of a piston compressor or the pressure in the load system via an idling control piston fitted in the cylinder head is to keep open, at least for a time, an inlet valve of the piston compressor. Incorporating the idling control piston in the cylinder head requires a design of the cylinder head which is complicated in terms of manufacture, stability and thermal aspects. The invention therefore proposes to simplify the cylinder head by arranging the idling control piston in a valve support which can be clamped between cylinder and cylinder head.
Patent DE-3340467-A1 (DE)
Inventor: DENK HERBERT
IPC: B23Q1/00

Patent DE-3343456-A1 (DE)
Title: Arrangement for operating a plurality of units on a shared data line
Inventor: BERTSCH EGON DIPL ING
IPC: G06F13/368
Filed: 1983-12-01
Abstract: To operate a plurality of units each having a data output on a shared data line, a comparison device and a control device are provided in each unit, for control. The comparison devices of the units are connected to one another and to the control devices by organisation lines. An individual unit whose control device is activated operates as a master, while the other units operate as slaves when the control device is deactivated. A data line access request from one unit is represented by a request signal on a first organisation line, which signal starts up an address counter provided in the control device. If the address converted by the counter matches the address of the requesting unit, the latter address interrupts the counting cycle by means of a signal on a stop line. A particularly advantageous application is in a data transmitting/receiving system with a plurality of transceivers and a plurality of operating units to control the dialogue between the operating units and the transceivers via two (long-distance) data lines with bidirectional transmission.

Patent DE-3345357-A1 (DE)
Title: Method for producing hot-wash-fast dyeings and prints on textile articles made of polyester fibres or blends thereof with cellulose fibres
Inventor: ROEHSER HELMUT DIPL ING
IPC: D06P3/54
Filed: 1983-12-15
Abstract: The washing fastness of dyeings with disperse dyes on certain polyester fibre articles under the intensified conditions of a domestic wash at 60-80 DEG C in a short liquor ratio does not suffice in many cases. In particular, this disadvantage relates to knitwear with high colour goods and low white goods contents made from polyester/cellulose fibre blends, for example sports jerseys, night attire and underwear. According to the invention, it has now been found that these deficiencies can be rectified by the selection of very specific individual dyestuffs for the dyeing of the polyester fibres or of the polyester components of fibre mixtures under otherwise customary dyeing conditions.
Patent DE-3403104-A1 (DE)
Title: Acoustic seal for joints between sound-insulating, double-layered wall panels
Inventor: GOESELE KARL PROF DR ING
IPC: E04B1/84
Filed: 1984-01-30
Abstract: The invention relates to an acoustic seal for joints between sound-insulating, double-layered hollow wall panels having a panel joining means configured in the form of a tongue-and-groove connection. Sound-insulating, double-layered hollow wall panels have been proposed whose two outer layers are connected to each other by means of softly sprung strips which are arranged on the edge regions of the intermediate cavity and are aligned flush with the end faces of the layers. A known arrangement of this type has the disadvantage that, when erecting the hollow wall panel with the help of jointing mortar, there is the danger that said mortar may be displaced along the strip, in alignment with the end faces of the layers, towards the centre of the panel and thus produce a bridge for structure-borne sound transmission. It is the object of the invention to eliminated these disadvantages. The object is achieved by the springs being of a softly sprung design and having a dynamic rigidity of 20 MN/m<3>. The springs may also be composed of relatively rigid material, for example rigid foam or plastic film, and exhibit a soft spring action effected by being shaped for instance in the form of a U.

Title: Pushbutton with a rubber mat
Inventor: WAGENKNECHT BENNO
IPC: H01H13/702
Filed: 1984-06-08
Abstract: A pushbutton (1) having an operating plunger (3), which is guided displaceably in the axial direction (2), over a bulge (6) (which is in the form of a truncated cone) of a rubber mat (8) is intended to be designed for more favourable functional characteristics, in the sense of a defined response pressure point and a good snap-back effect. For this purpose, a cylinder (13) of stiffer material is inserted into the covering wall (9) which is placed over the hollow-conical wall (12), a guide pin (15) preferably passing coaxially through said cylinder (13). The bulb (22) of a lamp (23) can be used as this pin (15), which lamp projects into the interior of the plunger (3) in the opposite direction to the operating direction. A supporting ring (19), which radially surrounds the hollow-conical wall (12) spaced apart from it and is pressed onto the rubber mat (8), additionally assists the concentration of the deformation work, and hence the snapping and restoring forces in the region of the hollow-conical wall (12) between its bulge covering wall (9) and the rubber mat (8). <IMAGE>

Patent DE-3433612-A1 (DE)
Title: Method of utilising specific advantages of different bottle closures on one bottle
Inventor: TEUTSCH GERD
IPC: B65D45/06
Filed: 1984-09-13
Abstract: In order to allow specific advantages of different bottle closures to act on one bottle, provision is made for bottles having a mouthpiece for closures which are not, or only limitedly, reusable to be fitted additionally with fasteners for wire hoop closures, which fasteners are mounted below the mouthpieces and are constructed in such a way that they allow the wire hoop closures to be removed easily by hand from one bottle and placed on another. Combined distribution can thus take place, in particular of beverage bottles, the majority generally being closed by closures which are not, or are only limitedly, reusable and a minority being closed by wire hoop closures, but the bottles all being identical. In parallel, distribution is also possible solely with non-reusable closures on bottles with fasteners for wire hoop closures. As a result, the user is provided in both cases with the possibility of closing any of these bottles which are not emptied all at once using a wire hoop closure.
Patent DE-3438921-A1 (DE)
Title: Pulsed power supply
Inventor: BREITENBERGER GERHARD
IPC: H02M7/5387
Filed: 1984-10-24
Abstract: The invention relates to a pulsed power supply for currents whose time functions have a freely selectable behaviour, based on the principle of adaptive control using pulsed actuating elements, the load-current behaviour being determined by a reference variable (20). As a result of the modification according to the invention of an adaptive discontinuous pulse controller (16) and its possible use in conjunction with a bridge circuit of the actuating elements (1, 2, 3, 4), it was possible to reduce greatly the power loss of the power supply. Incorrect connections of the actuating elements (1, 2, 3, 4) are prevented by means of a logic circuit (44) which is connected upstream of the inputs of the actuating elements (1, 2, 3, 4). Monitoring circuits (21, 22, 23, 24) and damping circuits (27, 28, 29, 30) increase the operating reliability of the apparatus.
