The frame pieces are joined together at each corner, as a result of which a framed photograph, a framed picture or the like is obtained.
Patent DE-3113406-A1 (DE)
Title: Firing chain for propulsion charges of tube weapons
Inventor: FETT JOSEF
IPC: F42C19/08
Filed: 1981-04-03
Abstract: According to the present-day prior art, the firing results of large-calibre tube weapons are not reproducible because the firing jet does not always strike the propulsion charge optimally, as a result of an eccentric offset occurring. In order to counteract the problem of ignition with an eccentric offset, a firing-jet catchment funnel is installed in the propulsion charge and has the object of always guiding the firing jet, which emerges from the firing duct, in an optimum manner onto the components of those parts of the firing chain installed in the propulsion charge, in order thus to create the best ballistic conditions for each shot since only in this way is it possible to achieve reproducible firing results.

Patent DE-3121723-A1 (DE)
Title: Process for treating the distillation residue remaining in the preparation of phosphorochloridothionates
Inventor: CAFFY RUSSELL BRYAN
IPC: C07F9/20
Filed: 1981-06-01
Abstract: In the process for disposing of the distillation residue resulting in the preparation of phosphorochloridothionates, this residue is placed in cold stirred water, a pumpable and storable sludge being formed. This sludge, with or without intermediate storage, is transferred at controllable rates for continuous or semi-continuous hydrolysis in downstream hydrolysis reactors. By-products of this treatment of the distillation residue formed are essentially sulphur, phosphoric acid and hydrochloric acid. By controllability, reliable in terms of process engineering, of the formation of the hydrolysis decomposition gases, the downstream plants required for treating these decomposition gases can be designed smaller than the known discontinuous hydrolysis processes. This applies in particular to the downstream combustion chambers, for the operation of which the fuel consumption can be noticeably decreased.

Title: Measurement transducer and control device, in particular for positioning workpieces
Inventor: PARTUSCHECK HELLMUT
IPC: G01B7/02
Filed: 1981-12-30
Abstract: The invention relates to a measurement transducer and a control device for positioning and measuring workpieces on machine tools, in particular automatic cylindrical grinders, in which the positioning of the workpieces in both axial and radial directions is necessary and the configuration of the end faces makes a measuring-lever clearance stroke absolutely necessary. The measuring signals produced are processed in the control device, a circuit element known per se being used for inverting the signals so that the machine tool is controlled with constant input variables even during different positioning and measuring directions. This measuring device of high accuracy permits universal attachment to the machine tool, it is suitable for two opposed radial and axial measuring directions with constant measuring range and large measuring-lever clearance stroke, delivers identical input variables for the machine tool, has an automatically acting change-over at the control device for the positioning and measuring at a workpiece in a machine cycle, and, at fixed or varied cut-off points, enables predetermined machining steps to be initiated on the machine tool.

Title: Process for utilising spoil from coal mining
Inventor: HOELTER HEINZ DIPL ING
IPC: C10L5/40
Filed: 1982-03-13
Abstract: Process for ceramicising spoil from mining establishments. It is known thermally to ceramise spoil arising in underground operation, in order to utilise it for certain fields of application. For this purpose, a process is proposed according to the invention in which the washing and/or crushing spoil is used, as a result of admixing domestic refuse and waste materials, as energy carrier and availability improver against caking in the thermal ceramicising field. The availability of the washing and/or crushing spoil as energy carrier and product improver is increased by admixing domestic refuse and waste materials and, by adding chemisorption agents, a further immobilisation of pollutants (HCl, HF, SO2 and the like) is achieved.
Patent DE-3211815-A1 (DE)
Title: Three-phase monitoring circuit
Inventor: KARRAIS GUENTER ING GRAD
IPC: G01R29/18
Filed: 1982-03-31
Abstract: When devices and systems are to be connected to three-phase networks, a particular phase sequence is required in most cases. This is particularly important in the case of reactive-power control systems which do not compensate for the reactive current in the case of a wrong connection and then result in considerable power costs. The invention shows a three-phase monitoring circuit which is so simple, and thus also inexpensive, that it can be installed in mass production as service aid in devices of the said type. According to the invention, two signals, which provide a signal by means of logical combinations in the case of an error, are derived from the mains. <IMAGE>
Patent DE-3212489-A1 (DE)
Title: Facade facing
Inventor: REICH REINHARD DIPL ING DR
IPC: E04F13/18
Filed: 1982-04-03
Abstract: A facade facing comprises light-admitting elements which are fitted at a distance from the wall of the building, so that ventilation is possible. The elements may preferably be constructed from impact-resistant plastic, such as for example acrylic glass, polycarbonate or polyester, as are commercially available for other purposes. The fitting of such a ventilated facade has the advantage that on the one hand the heat transition resistance of the entire wall is reduced, but on the other hand ambient heat, whether due to the ambient air or due to solar irradiation, contributes to heating up the wall of the building and consequently improves the energy balance. The facade facing according to the invention consequently combines the advantages of an unfaced solid wall (absorption of ambient energies) with those of a solid wall having an outer facing of highly absorbing materials (high heat transmission resistance).

Title: Apparatus for the optically conductive connection of two optical waveguides
Inventor: BOMMER HEINZ
IPC: G02B6/38
Filed: 1982-09-22
Abstract: In the case of the apparatus for the optically conductive connection of two optical waveguides, two sleeves (2, 3) designed like junction boxes are connected coaxially to each other by means of a number of flexible rod elements (1) arranged axially parallel and at equal intervals close to the circumference, so that a type of gripping cage is produced. The ends of the optical waveguides to be connected are introduced into the sleeves and the latter are twisted with respect to each other about the common axis. In the connecting region, the twisted rod elements (1) bear against the optical waveguides in the manner of a collet, centring and holding them in a frictional manner. The sleeves can be locked in this position. The junction-box-like apparatus is used for the splicing of single-core optical waveguide cables. <IMAGE>
Patent DE-3238213-A1 (DE)
Title: Rotary motor
Inventor: JAEHN EGON
IPC: F02B55/00
Filed: 1982-10-15
Abstract: Power machines and process machines are required in technology, which machines run reliably, inter alia with high efficiency, a favourable power/weight ratio and low stress on the environment. Conventional reciprocating pistons and rotary motors, compressors, pumps, turbines and converters fulfil these objects to some extent only inadequately.   The invention relates to a power machine and process machine of rotary construction. Said machine consists of an outer wheel and a smaller inner wheel, which is located therein, is borne eccentrically with respect to said outer wheel and, fixedly located either on the inner wheel or in the outer wheel, cams which are immersed to a greater or lesser depth in corresponding recesses of the other wheel, as a result of the eccentricity during rotary movement, the cam shape and internal shape of the recess being constructed such that, during uniform rotary movement (constant angular speed) they seal both wheels. While likewise being sealed on the face and end sides (at the contact point between the inner and outer wheels) the volume between the wheels, bounded by the cams, varies during the rotary movement. Because of the very low mass acceleration (in the case of any valve movements) and the relatively low friction losses (the side parts can also rotate with the rotor), using this type of construction it is possible to produce hydraulic and pneumatic pumps, motors, internal-combustion engines (see Fig. 1) etc., with low costs and very good efficiencies. <IMAGE>
Patent DE-3242840-A1 (DE)
Title: Low power high-pressure discharge lamp
Inventor: FROMM DIETRICH DIPL PHYS DR
IPC: H01J61/073
Filed: 1982-11-19
Abstract: In a high-pressure discharge lamp having metal-halide additives and a power of less than 100 W, the electrodes (4, 5) consist of a shaft part (18), which is located close to the seal, and of a second part (19) which is constructed as a helix and faces the discharge, adjacent turns of the helix part (19) not touching one another. The shaft part (18) and the helix part (19) of the electrode are advantageously produced from a single piece of wire. While, in the case of a lamp discharge vessel which is pinched on two sides, the axis of the helix part (19) essentially forms a straight line with the shaft part (18), in the case of a discharge vessel which is pinched on one side, the axis of the helix part is bent through 90 DEG  with respect to the shaft part. For protection against corrosion, the shaft part (18) of the electrode (4, 5) is surrounded by a conical helix (17) of high-melting-point metal, whose windings are closely juxtaposed. The special shape of the electrode (4, 5) results in faster starting of the lamp - even when it is hot. <IMAGE>

Patent DE-3300009-A1 (DE)
Title: Labelling machine for rotationally symmetrical articles such as bottles
IPC: B65C9/06
Filed: 1983-01-03
Abstract: The invention relates to a labelling machine for rotationally symmetrical articles, such as bottles (3), which are held in reception pockets (2) of a turntable (1) by one or more stationary support strips (8 to 12), in such a way that the bottles (3) rotate about their own axes when the turntable turns. This auto-rotation on the part of the bottles is stopped when a projection (17) collides with an adjustable nose. So that the bottles (2) do not cease their auto-rotation for other reasons, however, there is at least one support strip (10) of short sections which can be pivoted against the force of a spring (15) in such a way that the bottle is subjected to varying pressures during transport. A slight vibratory movement results from these varying pressures, which is not sufficient to stop the bottle (3) from being held in the reception pocket (2), but which is sufficient to overcome blockages, so that the bottle's auto-rotation is only stopped when the projection (17) comes up against the nose.

Title: Arrangement for monitoring a device for separating off metal elements
Inventor: ROEDDER HERBERT
IPC: B07C5/344
Filed: 1983-04-08
Abstract: Arrangement for monitoring a device for separating off metal elements, having a metal detector and a separating-off element swing-mounted at the end adjacent to the metal detector. In order to test the operativeness of the metal detector, "internal" damping of the metal detector is brought about by a test signal which is generated at regular intervals, said damping corresponding to the external damping by means of a metal element and triggering an output signal of the metal detector. For the functional monitoring of the separating-off element there is a signal generator which produces the actuation rhythm and whose response range extends into the movement path of the separating-off element. The separating-off element is actuated for in each case one actuation rhythm by the output signals of the metal detector which are brought about by the test signals and the time period for the actuation is compared with a predetermined time period. By means of the output signal of the metal detector between two test signals, said output signal being brought about by a metal element, the regular timing clock for the test signal is interrupted and re-started. The advantage consists in the fact that the functional testing of the metal detector and of the separating-off element takes place simultaneously.
