Title: Method and apparatus for burning a gas/primary-air mixture
Inventor: PIEPER THOMAS
IPC: F23D14/10
Filed: 1988-09-27
Abstract: According to a method for burning a pre-mixed gas/primary-air mixture, the diffusion region of the flame of this burning process is supplied, in phases, with additional gas which, if desired, has an air content which is insufficient for ignitability. Such a supply of additional gas serves to reduce the proportion of harmful substances in the waste gases of the combustion, but is only effective in this way if no premature ignition of this additional gas takes place before the entry into the diffusion region. In order to ensure this, the supply of this additional gas is restricted to periods of time which preclude premature ignition of the additionally supplied gas. For example, the supply of the additional gas can take place intermittently. An apparatus suitable for this consists of a burner rod (1) having mixture outlet openings (6) for the gas/primary-air mixture and two gas supply conduits (5) which run parallel on both sides of the rod and are provided with gas outlet openings (4) and which are alternately supplied with gas by means of a control device (7). <IMAGE>
Patent DE-3834608-A1 (DE)
Inventor: TESCHE BERND DR
IPC: B29C51/16
Filed: 1988-10-11
Abstract: The invention relates to a further development of the method for the manufacture of shaped parts or motor vehicle upholstery from thermoformable plastics films, webs or sheets by deep drawing according to Patent Application P 37 14 366.2. In this method, a moulding, an object or a web blank of the same or another material is placed in the deep-drawing mould with its fair side or decorative side on a predetermined area of the mould surface of the deep-drawing mould and/or the said area is fastened in such a way that the moulding, object or the web blank immediately comes to lie against the inner mould surface or in a depression or elevation of the deep-drawing mould. The outer resting side edges of the object are no distance or an average distance of less than 500  mu m away from the deep-drawing mould and the said object is subsequently enclosed or partially covered on its rear side, leaving the desired fair face exposed, by the formed plastics film, web or sheet or the extruded strip.
Patent DE-3839948-A1 (DE)
Title: Electrophoresis apparatus for carrying out horizontal or vertical gel electrophoresis
Inventor: ROGNER INGO
IPC: G01N27/447
Filed: 1988-11-26
Abstract: For different separation methods, two apparatuses are currently required, one for horizontal and one for vertical electrophoretic separation methods. When only one apparatus is used which fulfils these two objectives, one apparatus is thus saved. The novel gel electrophoresis apparatus is to be convenient to operate and to be universally usable for horizontal and also for vertical electrophoretic separations. A specially developed hinge which permits a buffer solution tank together with the separation chamber to be folded from the horizontal to the vertical and specially integrated electrodes for the two separation methods are the basis for an optional use of the novel gel electrophoresis apparatus for known and proven horizontal or vertical electrophoretic separation methods. The gel electrophoresis apparatus makes it possible to characterise macromolecules, in particular proteins and/or serum proteins by known electrophoretic methods which can be carried out horizontally or vertically, such as SDS-disc electrophoresis, gradient PAGE, isoelectric focussing, 2D-electrophoresis, in particular with polyacrylamide gels. <IMAGE>

Patent DE-3918600-A1 (DE)
Inventor: LANGHORST HEINZ
IPC: E02F3/85
Filed: 1989-06-07
Abstract: Trenching shovels for mechanically levelling a road surface require a flat bottom (11) and a pivoting levelling blade (16) so that the shovel can collect the excess sand and smooth the road surface when the vehicle coupled to the trenching blade reverses. In a known trenching shovel of this type, the guides which guide the trenching blade (16) as it pivots with respect to the body of the shovel (bottom 11; side walls 12) are located in the region of the trenching shovel in which the sand accumulates and are therefore exposed to intense wear. The trenching shovel described comprises guides (guide points (19)) arranged along an arc of a circle above the bottom of the shovel (11) so that when the trenching blade (16) pivots, the (small) distance between the lower edge (30) and the bottom (11) of the shovel remains approximately constant.

Title: Aperture takes IC engine cylinder lubricant for regeneration - from position in piston sleeve beyond stroke of lowest piston ring
Inventor: TAGGESELL JUERGEN DIPL ING
IPC: F16N31/00
Filed: 1989-12-18
Abstract: An IC engine of the Otto or Diesel type and two-stroke or four-stroke has a piston (1) reciprocating in a cylinder (10) lined by a piston sleeve (2), and sealed by rings (13) from the combustion chamber (11). A connecting rod is coupled in standard manner to a crank-shaft (6). An oil sump forms part of a lubricating oil circuit, wherein to prevent oil comtaminated by fuel entering the main lubricant supply, the used oil is fed to a regenerating circuit. The oil enters the regenerating circuit via an outlet (16) passing through the sleeve at a location beyond the stroke of at least one piston ring (13) at the end of the piston remote from the combustion chamber, but within the stroke of the piston sleeve itself. ADVANTAGE - Since only a small vol of lubricant is withdrawn for regeneration, wasteful regeneration of entire oil supply is not needed.

Title: Coherent long-time integration for monopulse radar - using aerial pair for angle and elevation detecting in aircraft coordinate system
Inventor: PANNERT WOLFRAM DR
IPC: F41G7/22
Filed: 1990-03-15
Abstract: The coherent, long-term integration for monopulse radar in rotary target searching heads, is carried out using a pair of aerials for detecting the azimuth and elevation angles fitted in a coordinate system coupled to the missile. For a phase monopulse process, the phase difference of the received signals between two spaced aerials is evaluated. The useful signal is extracted by coherent integration over a longer time period, e.g. of several twist periods. A specified reception signal is pref. transformed into an output signal with special characteristics. For the process the two input signals have their frequencies mixed down with the transmit frequency, while subsequently summation and differential signals are formed and amplified.
