Patent DE-2929561-A1 (DE)
Title: Permanent spring contact opening-closing force indication - given by averaging force transducer current for repeated forced openings
Inventor: JUERGENSONN WERNER VON
IPC: G01L5/00
Filed: 1979-07-19
Abstract: An arrangement permanently indicates the rest and/or closing contact forces of any type of contact spring. It involves applying continuously increasing force to the free spring end of the contact until it opens. They enable very accurate rapid measurement esp. for relatively small contact forces. The steadily increasing force is applied by an electrodynamic transducer without restoring or frictional forces. The opening of the contact is used to generate an electrical signal and is followed by a steady force reduction until the contact closes. The force is increased and decreased repeatedly and the average force transducer current, which is proportional to the force produced, gives a measure of the rest contact force. It is displayed by an averaging moving coil meter.

Title: Sulphur prodn. by modified Claus process - using catalyst for selective oxidn. of hydrogen sulphide to sulphur di:oxide
Inventor: BEAVON DAVID K
IPC: C01B17/04
Filed: 1980-10-25
Abstract: In the prodn. of S, a charge gas, contg. an acid gas stream contg. 7-100 (10-100) vol.% H2S and 70-130 (100)% of the stoichiometric amt. of O2 for the oxidn. of H2S to S, and a recycled gas, which is pt. of the residual gas contg. H2S and SO2 obtd. after condensation of S from the exit gas, is contacted with a selective oxidn. catalyst, which oxidises H2S selectively to SO2, with practically no SO3 formation, and converts the H2S to SO2 and S. Contact takes place above the initiation temp. of the catalyst and below an upper reaction temp. of ca. 454 (371) deg.C, which is controlled selectively by the amt. of recycled gas introduced into the selective oxidn. zone. The prod. gas stream, contg. H2S, SO2 and S, is cooled below the dew point of S to condense the S and give a cooled residual gas contg. H2S and SO2. Pt. of this cooled gas is recycled to the selective oxidn. zone and the rest is heated to a temp. high enough for introduction into a Claus conversion stage and passed to at least one of these stages for the formation of more S. No costly and difficult to control thermal reactor is necessary. The process is esp. useful for small plants with an output of max. 20 t S/day and needs little supervision.

Title: Guide for sliding doors of furniture, in particular cupboards
Inventor: STOISSER HANS
IPC: E05D15/58
Filed: 1981-01-15
Abstract: For a sliding-door leaf of a piece of furniture, the invention provides a side guide which is formed by a telescopic rail which is bent to form a bow, the concave side of which is directed towards the interior of the furniture compartment, and which, at one end, is connected to the piece of furniture such that it can be articulated about a vertical axis. The other end of the telescopic rail can pivot about said axis by means of a pull-out extension which is preferably formed as a three-point hinge. When transferring from the closed position into the open position, the sliding-door leaf thus also carries out, in addition to the laterally directed movement, a horizontal movement component at right angles thereto. In the case of two or more sliding doors, neighbouring sliding-door leafs are located, in the open position of one sliding door, parallel to one another and one behind the other with the visible surfaces in the same direction.

Patent DE-3114049-A1 (DE)
Title: Bituminous material finisher
IPC: E01C19/48
Filed: 1981-04-07
Abstract: Using a movable bituminous material finisher with a precompression and smoothing board and a tamping strip in front of it, it has formerly not been possible to achieve the necessary degree of compression of at least 98% required for high performance road surfaces. It was therefore necessary to drive rollers behind the finisher, which had to roll each surface unit 10 or even more times. The object of the invention is to create a bituminous material finisher with which a degree of compression of 98% can be achieved, so that subsequent rolling is no longer necessary. This is achieved by a compression element located behind the precompression and smoothing board, which bears down continuously on the surface of the precompressed bituminous material and is connected to an expansive force drive, with which pressure pulses may be directed downwards into the bituminous material without lifting the compression element. The drive for this compression element is expediently mechanical or hydraulic.

Title: Method for controlling illuminating light beams in an image reproducing machine
Inventor: UEDA SADAO
IPC: G02F1/11
Filed: 1981-04-09
Abstract: The invention relates to a method for controlling the illuminating light beams for use in an image reproducing machine such as a colour scanner or a colour facsimile. In this case, a light beam is fed into an acousto-optic deflector by which it is deflected in order to obtain diffraction light beams which fall into fixed optical paths and are utilised to expose a reproduction film. The diffraction light beams are controlled due to the fact that a frequency of an ultrasonic wave which is input into the acousto-optical deflector is varied in such a way that each diffraction light beam is capable of falling or not falling into the respective optical path. <IMAGE>

Title: Device for producing artificial stone blocks from concrete and similar materials
Inventor: GIRKENS FRIEDRICH
IPC: B28B5/04
Filed: 1981-05-23
Abstract: The invention relates to a device for producing artificial stone blocks from concrete and similar materials, in which the materials to be processed are introduced by means of a metering device into moulds located on flat supports and are subsequently compacted by means of at least one vibration device. Known devices of this kind have the disadvantage that the performance which can be obtained therewith in relation to the dimensions and production costs is poor. In addition, in known devices mould exchange often involves difficulties. The object underlying the invention is therefore to provide a device for the production of artificial stone blocks from concrete and similar materials, which, with relatively small dimensions and production costs, is distinguished by a much higher performance than the known devices of this kind and in addition makes possible automatic mould exchange. This object is achieved essentially in that the device has three working ranges (1, 2 and 3), arranged one behind the other in a frame with respect to the production sequence and each having two working planes (a-a and b-b) arranged with the same height one above the other, the distance of the upper working level (b-b) from the lower working level (a-a) being greater than the maximum height of the moulds required for producing the blocks. <IMAGE>
