Title: Combustible gas prodn. - from fermentation gas by compression and selective dissolution leaving high methane gas
Inventor: GEIGER KARLHEINZ
IPC: B01D53/14
Filed: 1980-06-27
Abstract: Prodn. of combustible gas by fermentation of organic substances is based on compressing the fermentation gas which consists of methane and carbon dioxide, and removing at least a part of the carbon dioxide. During the compression the fermentation gas is contacted with a liquid which dissolves carbon dioxide to a greater extent than methane. This pressurised mixt. is sepd to yield combustible gas with a higher methane content and a liquid with the dissolved fermentation gas percentage, from which most of the gas is then extracted. The degassed liquid is recycled to be contacted with the fermentation gas. This reduces to a min. the engineering effort for the redn. of the carbon dioxide percentage in the combustible gas, and produces a fuel gas of higher calorific value.

Title: Axial adjustment grooved work rolls - by eccentric bolts, where adjustment can be made before assembly rolls in rolling mill stand
Inventor: KUHN PETER PROF DR ING
IPC: B21B31/18
Filed: 1980-11-07
Abstract: The rolling mill has a set of two work rolls, which are each located between a pair of chocks. At least one of the chocks on the side of the mill opposite to the driving side is supported by an intermediate piece contg. a spherical bearing. The intermediate piece is located in a holder which can be located on the mill stand. The holder contains a bolt with an eccentric zone located in a hole in the spherical bearing, so that when the bolt is rotated through an arc the roll chock is adjusted axially, and the grooves in the work rolls can thus be accurately aligned w.r.t. each other. Conventional axial adjustment of the work rolls is undertaken when the latter are in the mill stand. The invention permits the adjustment to be made before the rolls are assembled in the mill, so time is saved.

Patent DE-3108979-A1 (DE)
Title: Process and apparatus for producing floating screeds
Inventor: BALTRUSCHAT FRANZ
IPC: B28C9/00
Filed: 1981-03-10
Abstract: The invention specifies a process for producing floating cement screeds, in which process first of all a pulverulent liquefier and a pulverulent stabiliser are added to the pulverulent cement. These additives are added to a part-volume of the cement and the entire cement quantity is rapidly mixed, using a turbine agitator, with the total amount of water required for the screed composition until a cement paste is formed. The cement paste is mixed in a further, separate mixer with the sand portion and the resulting free-flowing screed composition is pumped to the place of application and is levelled off on the building floor, essentially of its own accord, with a little low-frequency, mechanical assistance. An apparatus for producing the cement paste comprises a turbine agitator which runs around a vertical axis and the blades of which are restricted such that they press the material, which is to be mixed, against the base of the mixing trough which encloses the turbine agitator. A spiral pump for drawing off the cement paste is driven via an intermediate part which extends beneath the turbine agitator and through the mixing trough, has a non-round cross-section and thus, on the one hand, prevents the composition, which is to be mixed, from rotating with the turbine agitator and, at the same time, itself achieves a mixing action.
Patent DE-3111401-A1 (DE)
Title: Stable molybdenum catalyst for converting C3- and C4-olefins into unsaturated aldehydes and acids
Inventor: CHELLIAH DANIEL
IPC: C07C253/00
Filed: 1981-03-23
Abstract: A stabilised heteropolymolybdate catalyst starting material in calcined form, which contains anionic molybdenum in the defect state, is impregnated on its surface with certain metal cations. The stabilised starting material is obtained by incorporating an aqueous chloride ion-containing solution and a phosphorus tungstate, silicon tungstate, vanadium arsenate, silicon arsenate, phosphorus vanadate or silicon vanadate compound into the reaction product of a molybdate and a soluble phosphate, silicate or arsenate, and then carrying out drying and calcination. During the chloride ion stabilisation step, other metals can be incorporated in the preparation of the stabilised starting material. The starting material obtained is catalytically active in the conversion of unsaturated aldehydes into the corresponding unsaturated carboxylic acids with or without incorporation of the metal cation during the chloride ion stabilisation step. If the calcined starting material obtained is impregnated on the surface with a metal cation of Group VIII, preferably with cobalt and/or iron, and with a selenium or tellurium compound, the catalysts obtained have high activity and are capable of converting C3- and C4-monoolefins in a single stage into the corresponding unsaturated carboxylic acids.

Title: Method for the production of finned tube coils
Inventor: ROMBAUT HENDRIK
IPC: B21D11/07
Filed: 1981-05-22
Abstract: The invention relates to a method for the production of finned tube coils made of steel for installation in heat exchanger equipment. In order to provide a method by means of which it is possible to produce finned tube coils which are finned over their entire length and can be installed with relatively small bending radii in heat exchanger equipment, in particular in heat pumps, to form a compact unit, thus making full use of the heat of the medium flowing through the fins, and to do this without incurring the disadvantages of the prior art, the proposal is that use be made, as the starting workpiece, of a straight finned tube, the fins of which have been produced in a known manner by winding a strip of steel sheet helically around a smooth tube and then welding them together and where the fin diameter is approximately twice but no more than twice the diameter of the smooth tube, that some of the fins be milled off tangentially down to the surface of the straight smooth tube in local areas corresponding to the length of the subsequent bends in the tubes and on the subsequent inside of the said bends, after which the areas from which the ribs have been removed are to be heated locally to red heat and then bent immediately through 180 DEG  without the use of an internal filler with a radius which is approximately 1 to 1.5 times the diameter of the smooth tube. <IMAGE>

Title: Elastic push-button switch cap
Inventor: SADO RYOICHI
IPC: H01H13/702
Filed: 1981-06-05
Abstract: The invention relates to an improved push-button switch cap which is produced integrally from a rubber-like material and by means of which a key stroke can be implemented which is greatly increased in comparison with known push-button switches, before a snapping process occurs in the switch cap, to be precise whenever the central region of the switch cap is pressed, in order to close the contacts. The switch cap consists of a) a central pressure region, b) a first annular region which is connected at its upper end to the central pressure region and may have the form of a truncated cone (frustrum) or of a pocket with the opening pointing downwards, c) a second annular region which surrounds the first annular region and is connected thereto, and d) a flat base ring which is connected to the second annular region and by means of which the switch cap is arranged on the base plate of the switch. The ratio of the dimensions of the first and second annular regions is selected such that the first annular region does not bend before the second annular region has deformed or bent essentially around the connecting line between the second annular region and the flat base ring.

Title: Machine for producing weld seams on a thermoplastic sheet web
Inventor: BOHNET HELMUT
IPC: B31B70/00
Filed: 1981-07-11
Abstract: A machine for producing weld seams on a thermoplastic sheet web has an advance device which feeds the sheet web intermittently to a welding station where the sheet web is provided with a weld seam by a welding tool and its end advanced beyond the welding station is cut off. Said machine has a draw-back device which can be actuated when the advance movement of the sheet web, generated by the advance device, is interrupted and is intended for moving the most recently welded leading edge of the sheet web out of the range of the welding tool. The draw-back device has one strip on each side of the transport path, in the region between the welding station and the advance device, the pivot axes of which strips lie within a common vertical plane and which strips can be driven for a synchronous pivot movement, in which the direction of rotation of one strip is opposite to that of the respective other strip, and which strips are provided, in the region of their driver parts which are radially distant from the pivot axes and are provided for acting on the sheet web, with an elastically compressible material. The contact surfaces, formed by the compressible material, for acting on the sheet web have radial clearances from the pivot axes of the strips, which radial clearances are greater than the axial clearances of the pivot axes of the strips from the transport path.

Title: Loudspeaker enclosure or combination for stereo reproduction
Inventor: MOORTGAT-PICK WALDEMAR DIPL PH
IPC: H04S3/00
Filed: 1981-07-31
Abstract: In contrast to the usual loudspeaker arrangement for stereo sound reproduction involving separate loudspeaker enclosures set up with adequate spacing, which are fed with the left-hand (L) and right-hand (R) sound signal, the loudspeaker arrangement proposed here operates with loudspeakers which are arranged closely to one another and the radiating directions of which are offset with respect to one another by 90 DEG  and which are fed with the M = L + R and S = L - R signals. Using a single loudspeaker enclosure which radiates the M signal at the front and the positive or respectively negative S signal at the side, a largely true stereophonic sound image can be reproduced in the room by this means. Such a loudspeaker configuration is suitable in the various construction variants, described in greater detail, for, among others, equipment having small dimensions and in-built loudspeakers such as, for example, portable receivers, portable television sets, but also especially for single-enclosure loudspeakers for hi-fi systems when there are conditions of restricted space, and particularly also for installation in a motor vehicle in the centre of the rear shelf. A suitable matrix is supplied for feeding loudspeaker enclosures of such construction with the regular left-hand (L) and right-hand (R) signals.

Title: Light, in particular rear light
IPC: B62J6/04
Filed: 1981-09-03
Abstract: The invention relates to a light, in particular rear light, which can be attached to a mudguard of a two-wheeled vehicle by means of a holding element. In order to attach a light of this type to the mudguard reliably and securely, a not inconsiderable expenditure on production and installation was hitherto required. Moreover, particular difficulties arise if the light is to maintain an exact alignment on the mudguard so that the beam can also be directed in a specified direction. It is therefore proposed to design the light in such a manner that the holding element can be fitted from the outside onto the mudguard, the holding element having hooks which on both sides engage around and grip behind the lower edges of the mudguard or engage in holes provided in the region of the lower edges. In this way, the light is mounted by means of the holding element and a clamping device directly or indirectly on the outer surface of the mudguard, the base of the light, or a carrier on which the light is directly or indirectly arranged, resting on the surface of the mudguard. The said clamping device acts according to the invention essentially perpendicularly on the surface of the mudguard. <IMAGE>

Title: Device for transporting rigid board-like printing products
Inventor: KRAFT WOLFGANG
IPC: H05K3/12
Filed: 1981-09-24
Abstract: The transporting device comprises a horizontal transporting path on which board-like printed products are conveyed step-wise to a printing station and, after printing, are transported further out of the printing station. Transporting takes place with the aid of lifting rails which are displaceable back and forth along the transporting path and are lifted during the forward movement through slots in the transporting path, thereby lifting the printed products from the surface of the transporting path and carrying them along on their displacement route. At the end of the advancing section, the lifting members are lowered below the surface of the transporting path again whilst setting down the printed products and are moved back to their starting position. <IMAGE>
