Title: Biomass conversion to methane and manure - in two reactors in series with specified different temp. levels
Inventor: SCHNEIDER HANS DIPL ING
IPC: C12M1/107
Filed: 1980-11-13
Abstract: Gaseous methane is produced from biomass by circulating it intermittently in a first reactor and by homogenising it, using a heat exchanger for a side stream to heat it to a temp. of 55 deg. C. In a second reactor, the homogenising continues at 35 deg. C, using a pump to recycle a side stream through the heat exchanger to the first rectorreactor, if its temp. should drop below 35 deg. C. This system achieves an optimum conversion of biomass into methane gas and biological manure.

An adjustable shutter may be arranged in the region of the intermediate image. A quadrupole may be mounted in the second immersion lens (4) tube (8) for lateral shift of the particle.
Patent DE-3049503-A1 (DE)
Inventor: SARSTEDT WALTER
IPC: A61M5/34
Filed: 1980-12-30
Abstract: A blood extraction device is disclosed herein, which is an improvement over similar devices having a cylindrical extraction tube enclosing an air-tight piston and sealed with a closure cap having an axial projection which contains a self-sealing puncturable plug and is received within a movable tubular guide sleeve containing a double-ended cannula the rear end of which is enclosed by a deformable but resilient thin hose with a closed self-sealing rear end. The improvement resides in the inclusion of one or more slots on the guide sleeve and cooperating lugs on the projection, or vice versa, each slot having an axially extending portion and a peripherally extending portion, such that rotation of the rear cutting edge of the cannula is prevented during penetration of both the rear end of the hose and the plug, and rotation is possible only when penetration is complete. In this way, the self-sealing properties of both the hose and the plug are retained, and the resilience of the hose secures each lug in position in the peripherally extending portion of each slot.

Title: Polariser for circular-polarised waves
Inventor: SEDLMAIR SIEGFRIED
IPC: H01P1/17
Filed: 1981-03-18
Abstract: The invention relates to a polariser for circular-polarised H11 waves, in the case of which electromagnetic energy is split into equal parts in a first divider and, furthermore, each part passes through a 3dB directional coupler in such a manner that a total of four components are produced and these four components are combined in the correct phase in a waveguide. The object of the invention is to design such polarisers such that their production is simplified as far as possible. This object is achieved according to the invention by equal coaxial transitions (4, 5) from an input waveguide (1) opening into waveguides (6, 8) having a curved cross-section, by these waveguides (6, 8) being supplemented by further waveguides (7, 9), likewise having a curved cross-section, to form a complete circular shape and, in the further course, opposite narrow sides (11, 13) of the waveguides having a curved cross-section containing coupling openings (11', 13') in order to form the 3dB couplers, and, subsequently, by mutually identical capacitive probes (16, 17, 18, 19) opening from the four waveguides (6, 7, 8, 9) having a cross-section into an output waveguide (3). <IMAGE>

Title: Push-button switch
Inventor: MARQUARDT ERICH
IPC: H01H13/28
Filed: 1981-03-24
Abstract: The push-button switch, which is especially suitable for the construction of keyboards for office machines and the like, consists essentially of a pot-shaped housing which can possibly be constructed in two pieces and whose pot edge is sealed by means of the pushbutton. The upper end of a restoring spring is supported in the interior of the pushbutton, its lower end resting on a bent limb of a contact element and preferably being held against lateral deflection by an integrally-formed or fitted retaining element. The other bent limb of the supporting element rests on a shaft wall which has a step-shaped shoulder which allows sudden tilting in the direction of the arrow when the pushbutton is depressed in the direction of said arrow. The movable contacts can be fitted on either one or the other bent limb of the contact element. The stationary contacts are then positioned accordingly. The latter can be passed through to the exterior and form connecting elements, or can be part of a printed-circuit board. In order to create a keyboard, a plurality of such switch housings are produced integrally with a covering panel or are anchored therein. Located underneath the individual bases is a base panel, which preferably carries the stationary contacts.
Patent DE-3112073-A1 (DE)
Title: Premixing pilot burner
Inventor: OTMINGHAUS RAINER
IPC: F23D14/04
Filed: 1981-03-27
Abstract: The present invention relates to a premixing pilot burner for a gas-heated heat source, such as a gas geyser, gas-circulating heaters or boilers or gas furnaces. Such premixing pilot burners have a gas nozzle which blows into a mixing pipe for the purpose of suction of primary air. Usually, such gas nozzles have been arranged in such a manner that they blow vertically upwards. However, it is not only air which penetrates the inlet opening for the air to be drawn, but also dust which enters the region of the gas nozzle and is deposited there. The deposits lead to a change in the blowing behaviour of the gas nozzle and thus to a change in the gas/air mixture and consequently these contaminations have a decisive influence on the burning stability of the pilot burner. The aim of the present invention is to avoid this depositing of dust, and this aim is achieved essentially in directing the mouth of the nozzle downwards, preferably vertically downwards. Further embodiments, such as providing a dust screen, adaptation of the length of the mixing pipe in relation to its diameter and the shaping of the end of the mixing pipe support these measures.

Title: Front-loader round-bale lifter
Inventor: MOHR AXEL
IPC: B66F9/10
Filed: 1981-03-30
Abstract: The appliance serves for lifting round bales of hay or straw above the maximum lifting height of the front-loader rocker. The front-loader rocker is not lengthened during this. The appliance consists of an elevation of the front-loader bracket, of two guide rods which are mounted on the same plane and which always keep the frame in a vertical position, of the frame and of a carriage which is movable vertically within the frame. By means of a rope which is fastened to the front tractor drawbar jaw and which leads by way of three deflecting rollers through the carriage to a crossbar, the carriage is moved upwards within the frame when the front loader is being lifted. With the front loader in the lowered state, the vertically movable crossbar rests on two supporting battens which are firmly screwed respectively on the left and right to the frame bar and which can be mounted at different heights. The front-loader round-bale lifter can thereby be adapted to any type of front loader. The front-loader round-bale lifter does not require any additional hydraulics for its function.

Title: Acetabulum for hip endoprostheses
IPC: A61F2/34
Filed: 1981-05-14
Abstract: An acetabulum for hip endoprostheses for isoelastic, self-adhering, cementless implantation in a recess in the pelvic bone, which comprises a hemispherical or cap-shaped acetabular body (1) with approximately radially directed passage openings (9), is to be improved in terms of its long-term strength and permanent vibration resistance. For this purpose, the passage openings (9) are designed as outwardly widening funnels and are arranged in large numbers close to one another and offset in gaps such that the funnel edges of adjacent passage openings touch one another where possible. This perforated design of the acetabulum creates numerous attachment cavities into which the bone can grow in the course of time, the funnel-shaped design of these attachment cavities permitting the growing-in bone material to develop the usual physiological bone structure, i.e. in the wide areas of the attachment cavities a multiply braced framework composed of small trabeculae, whereas it develops the usual compact tissue surface inwardly towards the boundary layer. <IMAGE>
