Patent DE-3000657-A1 (DE)
Title: Semiconductor laser wavelength stabiliser - has noise voltage detected at photodetector, and has control circuit for temp. of and/or injection current through laser
Inventor: ARNOLD GUENTHER DR RER NAT
IPC: H01S5/0687
Filed: 1980-01-10
Abstract: The laser radiation of the semiconductor laser, whose emission wavelength is to be stabilised, is passed from the front or rear laser mirror through a dispersive optical element, or through an element whose transmission loss is wavelength-dependent. After passing through this element the laser radiation is received by a photodetector (3) whose noise voltage is also detected. The semiconductor laser (1) temperature and/or the injection current through this laser, is controlled by an electronic circuit (4) in such a manner as to keep the noise voltage, detected at the photodetector, at a minimum. Pref. this voltage is measured by a frequency exceeding 10 kHz, but smaller than 10 MHz. The lazer radiation may reach the photodetector through an optical filter of such type that the wavelength dependent transmission change will reach its maximum at the respective laser wavelength.

Title: Fine distance measurement sensor - having economical construction and using flexible spring carrying sensing piece and strain gauges
Inventor: KUCHENHART FRIEDRICH-WILHELM
IPC: G01B7/00
Filed: 1980-01-31
Abstract: A fine measurement sensor, esp. a distance transducer for a length measurement unit, has one or more sensors on a mounting piece, e.g. a plug gauge, and arrangements for conversion of the sensor movements into electrical signals. It is an economical, compact device substantially insensitive to contaminants, e.g. dust and moisture. It does not contain moving parts, such as linkages or rocker arms, or channels requiring a high degree of manufacturing precision. The sensing part (1) of the sensor is mounted on the free end of a flexible spring (2). The other end of the spring is fixed to the mounting piece (3) at a distance from its outer surface (3a). Strain gauges (4) on either side of the spring convert the sensing piece (1) movements into electrical signals.

Title: Firing system for anti-helicopter projectiles - takes target movement into account whilst missile is in flight, using flight path computer
Inventor: PLATZ WILLI DIPL PHYS DR RER N
IPC: F42C13/02
Filed: 1980-02-06
Abstract: The firing system initiates launcher (or gun) alignment from input data relating to the sighted target and the missile (or shell) used, such as measured target distance, air temp., air pressure, type of munition, powder temp., barrel wear, movement of sight etc. The target distance determined immediately before firing and the above input data are used to define the predicted flight time of the missile and inputted into a flight path computer. When the predicted and actual flight times are euqal, the missile is detonated by remote control.

Title: Transfer printing with mono:azo dye - from amino-benzisothiazole and aniline coupler, esp. for polyester
Inventor: GRUND NORBERT DIPL CHEM DR
IPC: C09B29/08

Title: Method for the production of metal powder or metal-alloy powder
Inventor: SCHREINER HORST DR PROF
IPC: B22F9/08
Filed: 1981-02-05
Abstract: The object on which the invention is based is to specify an improved method by which it is possible to produce even metal or alloy powders containing heavy metals by pressure-jet atomisation and with which the emission of metals or metal oxides is so small that there is virtually no pollution of the environment. The method according to the invention is characterised in that metal powder or metal alloy powder is melted in a closed melting space (100) filled with protective gas in a tiltable and heatable melting crucible (1), in that the melt is poured into a heated pouring funnel (3) arranged in the protective-gas space. The melt is then passed out of the pouring funnel (3), through an interspace (20), into an atomising nozzle (10) and sprayed into an atomisation chamber (11) under water pressure. The powder is collected in a collecting tank (12) with a closed water circuit (14). <IMAGE>

Title: Disc milling cutter
Inventor: WERMEISTER GUENTER
IPC: B23C5/22
Filed: 1981-05-23
Abstract: The invention relates to a disc milling cutter for milling axles, crankshafts or the like, with cassettes insertable into a one-piece, ring-like basic body and carrying cutting tips. The cassettes, with one of their foot surfaces facing the basic body, are radially supported on a circular-arc-shaped inner surface of the ring-like basic body and are axially secured by a ring rib of the basic body. Here, radial recesses are to be dispensed with and the cassettes can be braced in the peripheral direction of the cutter in the basic body without each cassette requiring a clamping or bracing means, and when radial clamping bolts are used these clamping bolts are not loaded in shear. To this end, the cassettes (5, 6, 7), while their faces bear against the faces of the adjacent cassettes, form an uninterrupted, uniform circle of cutting-tip holders. In this arrangement, one (6) of the cassettes has parallel faces (18, 19) or faces (18, 19) directed outwards towards one another, and at least one (7) of its adjacent cassettes has correspondingly inclined adjacent faces, and a clamping wedge (26) effective against the adjacent cassette (7) is arranged on one face (18) of the cassette (6) having parallel faces (18, 19) or faces (18, 19) directed outwards towards one another. <IMAGE>

Title: Bearing of a pivotable arm rest
Inventor: KRAFT SIEGFRIED ING GRAD
IPC: A47C7/54
Filed: 1981-08-19
Abstract: The invention relates to a bearing of an arm rest (11 or 12), which can be pivoted about a horizontal axle, on a wall part (2), in particular on the side piece of a backrest of a seating arrangement in a vehicle. The bearing comprises a journal (6), mounted in a guide (13), and two stop faces (8, 9), which bound the pivoting range, and a counter-stop (10) associated to said stop faces. In order to obtain a relatively large support moment and a sufficiently large pivoting angle which is independent of the constructional height of the supporting arm rest (12), it is proposed to connect the journal (6) at its one end rigidly to a plate (5) attached to the wall part (2). At the same time, said plate (5) contains the stop faces (8, 9) for the counter-stop (10) connected firmly to the arm rest (12). <IMAGE>
