Title: Miniature semiconductor laser diode - has diode chip on small thermo-electric cooler and laser beam focussing gradient index fibres
Inventor: DIEHL CHRISTIAN DIPL PHYS
IPC: H01S5/024
Filed: 1980-12-22
Abstract: A chip (11) of the laser diode (10) is mounted on a small thermo-electric cooler (12), and the emitted laser light is focussed by an enclosed gradient index fibre (14). The latter is made of glass and forms a so called self-focussing objective lens. The thermo-electric cooler is typically a Peltier element. The latter and the gradient index fibre may be adhered to a capacitive cooling element. The design provides a very small laser which is of stable wavelength, without any temperature-dependent wavelength changes. Thus it can be safely used with interference filters, without any acceleration drawbacks. The use of the self-focussing objective lens with fibres does not impede the laser beam focussing. The laser enables operational periods of less than one second.

Title: Calibratable circuit arrangement for stabilising the electric voltage existing between a first conductor section and a second conductor section
Inventor: NITSCHKE WERNER DIPL PHYS
IPC: G05F3/18
Filed: 1981-01-10
Abstract: A calibratable circuit arrangement is proposed which is intended to be used for stabilising the electric voltage existing between a first conductor section (1) and a second conductor section (2). For this purpose, the collector-emitter path of a series transistor (10) is provided in the first conductor section (1) and the part (11) of the conductor section (1) preceding the collector is connected via a dimensioning resistor (12) to the base of the series transistor (10). Furthermore, the base of the series transistor (10) is the starting point for a circuit branch which extends via an ohmic adjusting resistor (13) and via a Zener diode (14), to which the voltage is applied in the reverse direction, to the second conductor section (2). According to the invention, the series circuit of an ohmic fixed resistor (15) and of a further Zener diode (16) is connected in parallel with the series circuit consisting of the adjusting resistor (13) and Zener diode (14), the anodes of the two Zener diodes (14, 16) facing one another and the dimensioning resistor (12) being connected to the base of the series transistor (10) via the fixed ohmic resistor (15). This provides an integrable circuit arrangement at a relatively high control rate. <IMAGE>

Title: Process and apparatus for the production of elementary-thread nonwoven of stable surface
Inventor: LASCH GUNTER
IPC: D04H13/00
Filed: 1981-06-26
Abstract: The invention relates to the production of elementary-thread nonwoven on the melt-spinning or solution-spinning principle. The aim and object of the invention are to produce elementary-thread nonwoven of relatively low surface mass with high stability in the longitudinal and transverse directions in a cost-effective way. The solution according to the invention contains the coupling of a preferably hydraulic jet-weaving machine, on which a very "coarse-mesh" fabric is produced, with a modified device for the formation of nonwoven. A store is interposed between the two units. The fabric produced synchronously with the elementary-thread nonwoven is introduced into the process for forming the nonwoven, in such a way that elementary threads loop round warp and weft threads and a common consolidation can subsequently take place. The invention is used especially for elementary-thread nonwovens for use as packaging means.
Patent DE-3125813-A1 (DE)
Title: Collapsible mould core
Inventor: HOLDT JOHN WARREN VON
IPC: B29C45/44
Filed: 1981-06-30
Abstract: A collapsible mould core has an inner core part which forms first and second ends facing away from one another. The inner core part tapers in the transverse direction from the first end to the second end to a reduced diameter. A number of outer core parts are mounted on the lateral outer surface of the inner core part so as to be displaceable in the longitudinal direction between first and second slide positions. The outer core parts form first and second ends which correspond in position to the first and second ends of the inner core part, the outer core parts tapering, in the transverse direction, inwardly in dimension from their second ends to their first ends, to form an opposite taper to the inner core part. In the second slide position, the mould core has a smaller diameter in the transverse direction than in the first slide position. This permits the moulding of an article, for example a bucket, with a straight wall with an inwardly projecting edge around the mould core, whilst the latter adopts the first slide position. Then the removal of the article from the mould core can be carried out by shifting the mould core into the second slide position which makes possible removal of the bucket from the core.

IPC: B01D46/00
Filed: 1981-07-02
Abstract: The invention relates to a suspended matter filter having a filter cell, the filter frame of which is arranged in a filter housing via a surrounding seal forming a test channel to which a test device can be connected. The object underlying the invention is to create a suspended matter filter of the generic type mentioned at the outset, the filter cell of which ensures, with inexpensive manufacture, continuously reliable and comprehensive pressure testing of the test channel and, on the other hand, allows the replacement of the expensive and complicated test device by simpler and cost-saving test apparatuses. This object is achieved in combination with the abovementioned generic concept by the seal being formed from a sealing strip (18), which is attached to the filter frame (14) and is made of a material having entropy elasticity, which sealing strip lies against free ends (19, 20) of legs of a rigid channel profile (21) situated on the filter housing (11). Such a test device can be used in all gas filters having a high separation efficiency. <IMAGE>

Title: Part-open ventilation device for turn-and-tilt windows, doors or the like
Inventor: ROTH ERNST
IPC: E05C9/18
Filed: 1981-08-03
Abstract: A part-open ventilation device for turn-and-tilt windows, doors or the like is to acquire a design which, along with a short switching travel of the turn-and-tilt fitting available for its actuation, guarantees a relatively wide part-open position of the wing relative to the fixed frame and, in one and the same version, allows selective right-hand and left-hand fastening. For this purpose, it has a bolt extension (5) displaceable into a plurality of successive switching positions on the wing by means of an espagnolette (4). In the closing switching position (V), the bolt extension (5) can be placed behind a closing locking boss (17) on the fixed frame. In the turn-open switching position (D) and in the tilt-open switching position (K) however, it can be put out of engagement with the closing locking boss (17). In a fourth, namely the part-open ventilation switching position (S), the bolt extension (5) can be brought into engagement with parts-open ventilation locking webs (19 and 20) which are arranged offset towards the room interior in relation to the closing locking boss (17). The part-open ventilation switching position (S) for the bolt extension (5) is located approximately centrally between the turn-open switching position (D) and the tilt-open switching position (K). It is essential in such a part-open ventilation device that the bolt extension (5) fixing the part-open position of the wing relative to the fixed frame can respectively be arranged laterally offset out of the longitudinal mid-plane (9-9) of the espagnolette (4) and cover rail (3) in the direction away from the room side. <IMAGE>
