Patent DE-3018751-A1 (DE)
Title: Acousto-optic modulator using electro-acoustic transducer - fixed to cavity free body with modulating region for modulating incident light waves
Inventor: PETERMANN KLAUS DR ING
IPC: G02F1/11
Filed: 1980-05-16
Abstract: The modulator, consists of a fixed, cavity free body (20), made up of a single optical rod or several rods, and having one or more light wave forming regions (21,21'), and at least one light wave deflecting and/or modulating region (22). An electroacoustic transducer (27) produces an acoustic wave field (29) with a given modulation frequency, f, the unmodulated light waves being reflected at the acoustic wave field (29) the frequency F of these unmodulated light waves thereby increasing by the amount f of the modulated frequency of the acoustic wave field, giving F + f. If the acoustic transducer (27) and the attenuating material (30) are interchanged, the propagation of the acoustic wave field (29) is changed by 180 degrees, and if the unmodulated light waves are reflected at this acoustic field (29), the frequency F of the unmodulated light decreases by the amount f of the modulated frequency of the wave field, giving F - f. A modulator constructed in this way is operationally reliable when subjected to thermal and mechanical stresses, and can be produced to save weight and volume.

Title: Adjustable stroke limiter for hydraulic crane rams - uses pressure sensitive or position dependent limit valve to operate slide control valve
Inventor: BRUNNER RUDOLF
IPC: B66C23/90
Filed: 1980-06-16
Abstract: The stroke limiting unit is esp. for the hydraulic cylinders of a jib crane. A pump feeds a slide control valve, which operates the adjusting unit.

Title: Matted acrylic! glass prodn. - by distributing polymeric delustrant in matrix-forming monomer or prepolymer, polymerising, demoulding and tempering
Inventor: PAHL JOSEF
IPC: B29C70/72
Filed: 1980-07-26
Abstract: 04 matted acrylic glass prodn. organic polymer-based delustrants, which are difficultly soluble or insoluble in the matrix polymer or its precursors, are very finely distributed in the monomers or prepolymers used for matrix polymer prepn. Polymerisation to acrylic glass is effected in standard manner in horizontal casting mould compartments. After unmoulding, the sheets are tempered, pref. at 100-200 (150-170) deg.C, and subsequently drawn. The polymeric delustrants can be used as beads or powders. Powder grain-size distribution is pref. such that over 80% powders have grain-size below 400 mu and esp. less than 20% have grain-size 400-600 mu. On using delustrants having a lower specific wt., e.g. below 0.945, than the monomers of prepolymers used in matrix polymer prepn., the delustrant particles rise to the horizontal mould surface and form a "ceramic mat" top surface after tempering and/or drawing. Satisfactory matting is achieved.

Title: Vehicle braking sensor - uses heavy bearing-mounted mass, with adjustable spring-loading, as momentum switch
Inventor: DUENISS PETER
IPC: H01H35/14
Filed: 1980-08-27
Abstract: The switch unit consists of a rectangular-shaped housing (1), made of metal or plastics, having a central rectangular recess (2). A heavy, semi-triangular-shaped mass (5), is pivoted by a small ball-race inside the central recess (2). This heavy mass (5) has a small recess (9) drilled in its underside, into which the end of a spring (10) enters, its pressure against the mass (5) being adjusted by means of a lockable screw (12) entering through the main wall of the housing (1). The top edge (16) of the mass (5) which ends in a point, rests against the underside of a lever arm (17) attached to a micro-switch (18) and is held in this position by the spring pressure. The unit can be mounted horizontally or vertically with the spring (10) facing the direction of travel of the vehicle. When braking occurs, the heavy mass moves against the spring (10) and allows the lever arm (17) to release the operating button (20) on the switch (18), giving immediate indication and warning.

Patent DE-3102559-A1 (DE)
Title: Tool for grinding or polishing metal surfaces
Inventor: OESZUET MUEMIN
IPC: C08J5/14
Filed: 1981-01-27
Abstract: The invention relates to a tool for grinding or polishing metal surfaces, which is used for rubbing grinding or polishing paste on the metal surface. In the case of tools which have a tightly packed structure and consist of soft metal or plastic, there is the danger that the abrasive bodies are held firmly in the melt of the grinding or polishing paste and thus lead to the formation of scratches during the grinding or polishing procedure. In order to avoid this, the tool is produced from a binder with metal-powder parts which are embedded such that they are uniformly distributed, the hardness of the binder being lower than the hardness of the metal powder and the hardness of the metal powder parts, in turn, being lower than the hardness of the abrasive bodies in the grinding or polishing paste.

Title: Twin piston engine
IPC: F01B7/14
Filed: 1981-03-03
Abstract: A twin piston engine in which two pistons are each acted upon from a common combustion chamber is designed so that the pistons are offset in relation to one another, the four-stroke rhythm being geared to the one piston whilst the other piston lags behind. This results in a prolonged combustion period and hence in addition to a prolonged working period in more complete combustion.
Patent DE-3115680-A1 (DE)
Title: Electrically operated actuating drive
Inventor: NEUHAUS DIETMAR
IPC: G12B1/04
Filed: 1981-04-18
Abstract: The invention relates to a continuously controllable, electrically operated actuating drive having large actuating forces, which is used in areas which do not require high actuating speeds. This covers, especially, applications in the field of heating and air-conditioning technology. The actuating drive is constructed with the aid of two temperature movement sensors which are mechanically connected in opposition to one another, the functional status being determined by the temperature difference between the two temperature movement sensors. A temperature difference between the two temperature movement sensors can be produced by electrical resistance heaters, and a specific functional status can thus be set. Measurement of the temperature difference between the two temperature movement sensors provides information on the functional status of the actuating drive.

Title: Combination sphere
Inventor: LAKIES HOLGER
IPC: A63F9/08
Filed: 1981-10-13
Abstract: The invention relates to a game of skill whose objectives are comparable to those of the familiar "magic cube" of the Hungarian inventor Rubik. The cube designed by Rubik and comparable constructions have the disadvantage that the article is made up from a plurality of groups of individual parts for which fixed positions, dictated by the structure, are predetermined. The object underlying the combination sphere was to develop the construction in such a manner that all the individual items to be assigned to it are of completely identical shape. The problem was solved by means of a disc contained in the interior of the sphere which is divided at the centre and, by connecting the two half-discs by means of an axis bolt, can be rotated about the horizontal axis. The individual segments of the sphere are fitted into the angular groove milled into the circumference of the disc at top and bottom, and can thus be moved through a full circle about the vertical axis of the disc. As a result of this mechanism, none of the individual segments has a fixed position dictated by the structure.
