Title: Improved monoski which can be broken down into two separate elements
Inventor: PIANA ANGELO
IPC: A63C5/03
Filed: 1988-02-26
Abstract: A monoski is described which consists of two board elements that can be separated from each other and of securing elements by means of which the said board elements can be connected to each other side by side and thus form a monoski; the principal feature resides in the fact that the inner edges of the board elements have a counter-profile, while the securing elements simultaneously consist of removable clamps which are suitable for connecting the counter-profiles of the edges to each other in a substantially positive-fitting manner; in this manner, a single bearing surface is formed from the individual running surfaces of the two board elements, which have approximately 1 1/2  times the width of a normal ski.

Title: Float-controlled regulating device for changing the flow cross-section of the outlet opening of a liquid container, especially a rain retention basin
IPC: E03F5/10
Filed: 1988-05-21
Abstract: In a float-controlled regulating device for altering the flow cross-section of the outlet opening (3) of a liquid container, especially a rain retention basin, as a function of the height of the liquid level, a throttle slide (6) which can be guided over the outlet opening (3) is connected via transmission elements (9, 12, 20) to a float (18) so as to produce movement. The float (18) is arranged in a gas-filled housing (25) open only on its lower side, in which the liquid level (27) adjusts itself as a function of the volume of the enclosed gas determined by the pressure corresponding to the height of the liquid level in the container. In this way, the water level (27) in the gas-filled housing (25) executes only fluctuations which are specifically directly proportional to the fluctuations of the water level in the container but are significantly smaller than the latter. An exactly determinable water level in the housing (25) is thus assigned to each water level in the container, so that water levels of any height can be directly detected and transmitted as control variables. <IMAGE>

Title: Ring seal with an annular carrier and seal coating
Inventor: GUTSMIEDL HEINRICH
IPC: F16J15/02
Filed: 1988-08-19
Abstract: In a ring seal for enamel flanges, an annular carrier in the form of a corrugated steel ring is wound with a PTFE packing cord in such a way that the individual turns rest tightly against one another on the corrugated steel ring. By virtue of the radial orientation of the material of the PTFE packing cord, the flow behaviour of which is not very pronounced in the longitudinal direction but very pronounced in the transverse direction, flow of the packing-cord material during the compression of the ring seal is kept within narrow limits and the flow of the individual, approximately radially extending packing-cord sections in the transverse direction is limited by the fact that the material of adjacent sections is supported each on the other. As a result, adequate packing material remains between the flanges, thus allowing even relatively large irregularities in the sealing surfaces of the flanges to be compensated for.

Title: Load wagon for bales of hay or straw - incorporates system for loading and off-loading bales
Inventor: CONZELMANN MATTHIAS DIPL ING
IPC: A01D90/08
Filed: 1989-07-25
Abstract: A wagon (1) for bales of hay, straw, etc., has a loading (and offloading) system which lifts the bales from the ground to loading-platform height, turns them by 90 deg. to the direction of travel, and shifts them one bale-length on a loading area.  Several bales are thus handled up to a maximum width corresponding to that of the vehicle. A row of bales thus formed is raised until enough space is available for more bales, and are held with a grab mechanism.  Raising and shifting is repeated until a stack of bales is formed corresponding to the height of the system, and the whole stack is then shifted by one bale-width to make room for another stack.  This process is repeated until all the bales are loaded or until the whole load area is full. USE/ADVANTAGE - The wagon is suitable for work on slopes, functions properly even with delay or acceleration processes, and has optimum load capacity.

Title: Electrostatic filter insulator cleaning - by compressed air jets controlled by voltage drop
Inventor: LEONHARD ROLF DR ING
IPC: B03C3/70
Filed: 1989-08-23
Abstract: The insulators of electrostatic filters to remove soot from combustion prods. or Diesel engine exhaust gases are cleaned by applying a pressurised fluid, specially compressed air which is blown against the surface of the insulator. The voltage across the filter is monitored and if it drops below a lower threshold, the air blast is initiated. The deposition of a layer of soot (5) on the insulator (2) of an electrode (3) will reduce the h.t. voltage of a source of supply (4) relative to the casing (1) which can be read on the columeter (19). An ON-OFF controller (6) responds when the voltage drops below a set point and actuates a pilot valve (7). Compressed air from a cylinder (10) is now admitted to several jets (8) in a circle around the electrode (3) which are also pushed in the dotted position (14'), when the air is cut off, a spring (13) returns each jet to a safe distance (L), e.g. 30mm for 17 kV. ADVANTAGE - This removes soot deposits in time and guarantees a reliable function over long periods without breakdowns.
