Abstract: A gas stream with heat value 500-7500 kj/m3 contg. at least one 1-7C hydrocarbon, obtd. after sepn. of liq. hydrocarbons, from in-situ combustion of undergound deposits, is mixed with less than the amt of air required for complete combustion, heated and burnt on a catalyst of Pt and oxide of a Group II A, VIII B or VIII (up to atomic no. 45) or lanthanide metal, Cr, Zn, Ag, Sa or Sb, or a carrier. The hot exhaust gas is then expanded in a gas turbine, which drives an air compressor supplying the air for in situ combustion. Method is used for disposal of gas mixts. from in-situ combustion of viscous oils left in formations, shale oils, tar sands and coal seams too deep or too thin for mining, and of industrial gas streams contg. H2 and CO from incomplete combustion, solvent evaporation, etc. The required constant gas turbine temp. is achieved with a constant air supply despite fluctuations in heat value of the gas mixt. CO content of the exhaust gas is reduced to acceptable limits, the unburnt component being mainly CH4.

Title: Biomass for animal fodder - produced by partially drying biological sludge from animal manure processing and neutralising with acid
Inventor: EICHLER DIETRICH DIPL ING
IPC: A23K10/12
Filed: 1979-07-21
Abstract: In the treatment of biological sludge from manure processing plants in industrial animal production, in which the biological sludge obtd. from a microbiological process run without additives is substantially dehydrated, the biological sludge, dried to a dry substance content of 5-10%, is adjusted from its alkaline pH to a pH 5-7 before direct feeding to animals or before drying. The biomass obtd. is suitable for use as animal fodder. The microbiological process is carried out with pH-modifying additives, neutralisation or acidification only being carried out at a later stage. This reduces the amt. of acid required, thus improving the economics of the process.

Title: Instantaneous measurement of high voltages - using delay element to compensate for sample-and-hold control delay circuit
Inventor: STRAUSS WERNER DIPL ING
IPC: G01R19/04
Filed: 1979-09-17
Abstract: An arrangement for measurement of instantaneous values of pulsed or periodic voltages is esp. for measuring peak or breakdown values of shock or a.c. voltages. It is applicable to h.v. test and measurement equipment and can be used for switching shock voltages of optional time profile as well as for full or partial lighting shock voltages. The voltage being measured is passed a sample-and-hold circuit via a delay element and is stored for a certain time so as to compensate for the delay of the sample-and-hold control signal delay of about 10 nanoseconds. The delay element time constant is chosen to ensure that the sample-and-hold control signal causes a hold if a sudden input voltage breakdown occurs.

Title: Electronic adder and subtracter in BCD-8421 code with decimal display
Inventor: MERKLE PAUL
IPC: G06F7/494
Filed: 1981-01-22
Abstract: The electronic parallel adder according to the subject matter of the invention comprises decades according to Figure 1 (one decade per decimal digit). The upper part of this decade is the decoder circuit, which displays the four-digit dual number decremented by 6. This is required because the number 6 (LHHL) must be added to the number 0 (LLLL) before every addition in each decade in this adder. The inputs are thus occupied and the addends are successively BCD-coded and added via the A-inputs to the previous sub-total. Insofar as only two addends are added together, the cardinal number 6 can subsequently be automatically added in each decade and in this case one addend is fed to the A-inputs and the other addend is fed to the B-inputs of the system. The feedback lines (d) enable the n-fold addition of addends in very simple fashion. The corresponding parallel adder-subtracter has switchable tetrads and normal decoding circuits and can thus be used for addition and subtraction. <IMAGE>

Title: Groove-grinding machine for spectacle lenses
IPC: B24B9/14
Filed: 1981-02-21
Abstract: By means of the invention, spectacle lenses consisting of known materials can be provided with grooves in a precise manner on the peripheral surface and in any curved progression. This makes possible the novel guiding of the spectacle lens in conjunction with the newly configured grinding table. The invention is represented in the figure and is composed of a housing (2) which contains the drive, of the grinding table with circular lens bearing means (3), of the guiding rollers (4), of the lens bearing means comprising vertical guide (5), horizontal guide (6) and pivot guide (7), of adjusting screw (8), of guiding-roller adjustment (9), of suction means (10) with clamping screw (11), of grinding-wheel moistening means (12) and of guide part (13). The novel feature with respect to known machines is that all conventional spectacle-lens forms can be provided with a groove of uniform depth. This is based on the knowledge that scanning the spectacle-lens form has to be carried out immediately next to the groove to be ground in. This problem is solved according to the invention by means of a circular, facetted bearing table. Machines of the known type have a flat bearing table, imprecise lens guiding and, consequently, an uneven, deep groove configuration results. <IMAGE>

Title: Plastic screwcap with compensation for thread tolerances
Inventor: HEINLEIN HANS
IPC: B65D51/16
Filed: 1981-03-06
Abstract: In the case of a screw cap (1) which is preferably provided with means of ensuring that the original contents have not been tampered with and/or to make the container childproof, tolerance compensation is to be carried out and undesired automatic back-twisting of the screw cap (1) once it has been screwed on is to be prevented, which process is essentially carried out by means of vertical or horizontal elastically deformable webs (14, 17), the webs either being guided parallel to the axis in a gap (13) in the thread (10) or being arranged on the internal thread parallel to the turns of the thread. The advantages of the solution according to the invention are that the webs (14), which are parallel to the axis, remain in constant contact with the outside thread of the container even in the event of elastic deformation. <IMAGE>
