Patent DE-3027743-A1 (DE)
Title: Multiple core optical transmission element - uses prestressed light wave conductors inside extruded sheath
Inventor: PASCHER HELMUT DR ING
IPC: B29C48/00
Filed: 1980-07-22
Abstract: The multi-core optical cable is manufactured from individual light wave conductors (LW1,LW2,etc) which are paid out from the desired number of supply spools (VS1,VS2 etc) at the input side of the machine. The conductors are pulled from the spools by a positive friction roller system (ZTV), which imparts a length thrust to the conductors, so that they reach the following processing equipment with a pre-tension. The conductors (LW1,LW2,etc) leave the pull-off system and enter capillary tubes (KR1,KR2,etc) slightly larger internally than the conductor diameters. From these, they are fed to the outlet of an extruder (EX), where the protective sheath (SH) is formed, together with tensioning threads (ZE) necessary to give the finished cable its strength. As the conductors leave their respective capillaries, they take on a wavy or coiled configuration which gives the desired over-length. A filling medium (FM) also fed into the sheath at the same time, keeps the conductors in position inside the sheath, and retains the over-length necessary to allow the cable to be flexed without straining the cores.

Title: >>Transistorised hearing aid<<
Inventor: GOLDSCHMIDT RAINER
IPC: H03G3/12
Filed: 1981-02-27
Abstract: A transistorised hearing aid is proposed whose means for amplification control are intended to be designed in such a way that the distortion factor and the noise of the hearing aid are reduced. The means for gain control used in the pre-amplifier stage of a hearing aid comprise a series circuit composed of a setting resistor (22) and a capacitor (21), which is provided in the negative feedback path of at least one pre-amplifier stage (19). The capacitance value of the capacitor is selected so that the capacitor has the lowest possible impedance for the lowest audio-frequency which is to be transmitted. A transistor, which is controlled by means of a DC control voltage (USt) derived from the operating voltage (UB), can be used instead of a potentiometer as a setting resistor. <IMAGE>

Patent DE-3114370-A1 (DE)
Title: Embroidering machine
Inventor: REICH RUDOLF
IPC: D05C11/16
Filed: 1981-04-09
Abstract: In an embroidering machine, in which the individual elements of the embroidering tools for stitch formation are driven from a single rotating drive shaft, in such a way that the cycles of movement necessary for stitch formation or pattern formation are converted into a to-and-fro movement, there are provided sections with bearing and fastening arrangements at a spacing of 8/4 french inch for receiving push-in baseplates having individual 4/4-embroidering points which can be modified as desired in the repeat structure and which are connected to mini-cam discs arranged on the section shaft or to corresponding control elements for stitch formation; depending on the type of embroidering machine, the sections execute the axial needle stroke horizontally or vertically, and the sections have section embroidering heads laterally at the widest needle spacing. Consequently, the complicated repeat-changing pattern apparatus can be avoided, whilst this pattern technique is fully maintained, and the widest needle spacing can be utilised as a free space, formed on both sides of the section, for observing and operating each individual knitting point, but at the same time the section inner space necessarily obtained can be used on the needle side for accommodating embroidering aids. <IMAGE>

Title: Twin-wire section
Inventor: ZAG HEINZ
IPC: D21F9/00
Filed: 1981-06-11
Abstract: Twin-wire section for a paper or cardboard machine, having an essentially horizontally extending lower wire (2) onto which an upper wire (5) is placed. The two wires (2) and (5) form with one another a twin-wire zone, in which they jointly first loop round part of the circumference of a forming cylinder (7), specifically starting approximately from its lower vertex line over a looping angle of approximately 45 DEG . The two wires (2) and (5) thereafter loop round part of the circumference of a supporting cylinder (10) arranged in the lower wire (2). The forming cylinder (7) has a storage volume on its circumference. In the looping region, screening water penetrates into the storage volume and is thrown out again (arrows 23) behind the run-off point (98) of the two wires (2) and (5). The screening water is intercepted by a trough (110) and discharged laterally from the upper wire (5). The trough (110) has an upper covering wall (111) with a front edge (112) which extends along the casing of the forming cylinder (7) in the vicinity of the run-off point (98). As seen from inside the trough, the covering wall (111) is concavely curved and is matched to the throw parabola of the screening-water jet (23). <IMAGE>

Title: Sauna oven
Inventor: MUEHLBERGER EGON ING
IPC: A61H33/06
Filed: 1981-07-14
Abstract: The invention relates to a sauna oven with stones (4 and 5) as heat accumulator and a gas burner as heat source. It is the object of the invention to achieve a favourable dissipation of waste gases coupled with a high coefficient of heat utilisation. The procedure to achieve this is such that the waste gas channel (3) is arranged so as to be telescopically displaceable in the fresh air channel (2). The fresh air flowing around the gas channel is thereby preheated, so that the efficiency is increased; the telescopic extension simplifies discharge of waste gases into the open air. In that case, the free end is located outside the sauna space and can thus be provided from the outside with the heating and control unit (10), for example, so as to lie under a roofing. <IMAGE>

Title: Supporting stand for bar-shaped supports, in particular length-adjustable ceiling supports in shuttering construction.
Inventor: FOELL ERWIN
IPC: E04G25/00
Filed: 1981-08-08
Abstract: In order to stabilise shuttering supports (2), use is made of a supporting stand (1) having a central post (11) which has, at its two ends, coupling devices (12) which permit a lateral insertion of the support tube (3) and a fixed connection just above the standing surface (6) and at a relatively great distance above said surface. On the central post (11) there is fixedly attached a first obliquely positioned foot strut (16) which, in turn, is supported by a foot crossmember (18) just above the floor surface, at the lower end of the central post. Two further supporting elements have foot struts (161) and crossmember struts (181) which are welded together close to the foot plate (17) and are articulated on the coupling pieces (12) of the central post by means of pivot bearings (19) attached at their free ends such that they can be pivoted out of the operating position into a transporting position, up against the fixed foot element (14). The supporting stand (1) is longitudinally adjustably attached to the shuttering support and, owing to the large spacing of the fixing points, is in flexurally rigid connection therewith, this ensuring a high degree of stability. The supporting stand (1) can be combined with supports of different cross-sectional dimension. <IMAGE>

Patent DE-3133601-A1 (DE)
Title: Method and apparatus for the production of a split tube or a spiral tube with circumferential notches
Inventor: VOGELSANG JOERG
IPC: B21C37/12
Filed: 1981-08-25
Abstract: Split tubes or spiral tubes have hitherto been produced by a process in which a flat metal strip has first of all been notched on one or both sides and, after the notching operation, fed to a tube profiling device. This method of proceeding is associated with disadvantages especially where the flat metal strip is composed of a steel with a high carbon content. This material is work-hardened by the notching process and, as a result, becomes very brittle, so that a fracture of the length of the material in the tube profiling device in the region of the previously produced notches may easily occur. In contrast, the invention envisages a process in which the flat strip of material is first of all formed in a profiling device to give a split tube or spiral tube (3) and then notched at the circumference. For this purpose, the invention provides a notching device with a revolving tool carrier (51), the notching tools (55) of which are brought into contact with the surface of the spiral tube (3) at intervals for only a short period of time. Contact occurs at least twice for each notch (6) but the two contacts are circumferentially offset relative to one another. By positioning the notching device after the profiling device and by virtue of the special design of the notching device, it is now possible to produce notched profiled tubes (3) from flat metal strips composed of steels with a high carbon content. <IMAGE>
