Patent DE-3627054-C1 (DE)
Title: Sealing arrangement for a shaft
Inventor: KIRCHNER CHRISTIAN DIPL-ING
IPC: F16J15/40
Filed: 1986-08-09
Granted: 1987-12-03
Abstract: Sealing arrangement for a shaft with a seal housing, at least one revolving sealing-ring holder in the seal housing, a shaft with pumping grooves distributed over the circumference and a floating sealing ring in the sealing-ring holder, a fluid medium in the spaces on both sides of the floating sealing ring having different pressures. The pumping grooves are arranged in a region of the shaft which corresponds approximately to half the axial width of the floating sealing ring and adjoins the space under the higher static pressure. The floating sealing ring leaves free, relative to the shaft, a sealing gap in which the fluid medium forms a fluid layer in hydrodynamic or aerodynamic equilibrium in which the static pressure falls to the pressure of the space at the low pressure and out of which leakage fluid emerges. <IMAGE>

Inventor: EBELING WOLFGANG DIPL-ING
IPC: E21B19/24
Filed: 1987-08-06
Granted: 1988-06-09
Abstract: The invention relates to a catch device (1) for a drill string of a rock-drilling machine, having at least two opposite clamping jaws (3, 4) which enclose a drill rod (2), can be displaced into clamping position in guideways (5, 6, 41) of a link (49, 50) by a clamping piston (11), and in the unclamped position can be swung out around one swivel joint (14, 15) each of the link (49, 50). The object of the invention is to create a catch device (1) of this type which during the clamping operation centres the drill rod (2) or the end of the drill string projecting from the borehole in an exact concentric position and also guarantees as large a passage area as possible between drive head of the drilling machine and borehole mouth. This object is achieved according to the invention essentially in that a stop is provided for each clamping piston (11) in the clamping cylinders (9, 10), which stop, after an idle stroke (a, c) of the clamping piston (11), can be reached by a counter stop (20, 31) attached to it (11) or to its piston rod (7, 8), and the clamping piston (11) can be displaced further in the direction (12, 13) of the clamping position of the clamping jaws (3, 4) only after a certain pressure is exceeded on the piston side (25). <IMAGE>

Title: Fuel injecting system for IC engine - has central EM measuring valve apportioning pumped fuel to each cylinder according to engine type and working state
IPC: F02M41/06
Filed: 1990-11-30
Granted: 1992-04-30
Abstract: A central e.m. metering valve allocates pressurised fuel as pumped to each cylinder to suit engine status and parameters. A distributor is synchronised with ignition sequence or camshaft rotation to admit the fuel to injection valves which pass fuel to air lines leading to the cylinders and open and close automatically regardless of fuel pressure. The valve unit is driven by an hydraulic motor (12) operating as a displacement machine. The motor starts under the pressure and throughput of fuel pumped by the fuel pump (2) each time the metering valve opens and is stopped after a preset turn angle of the rotary slide (28) of the distributor. ADVANTAGE - Long term injection system offers optional arrangement and deployment of components avoiding electric motor connetions etc.

Title: Copying by exposing material to change adhesiveness and applying toner - which becomes more adhesive on exposure, esp. for making multicolour negative proof with overlapping colour areas
Inventor: GROSSA MARIO DR
IPC: G03F7/28
Filed: 1992-08-25
Granted: 1993-09-30
Abstract: Copying process involves (a) coating a support with a radiation-sensitive layer (I), the adhesiveness of which can be changed by exposure to actinic radiation; (b) changing the adhesiveness of certain areas by selective exposure; (c) applying a toner (II), which adheres to the adhesive areas; and (d) removing excess (II) from the other areas. The novelty is that the adhesiveness of the (II) used can be increased by exposure to actinic radiation. For multicolour copies, stages () to (d) are repeated at least once. (II) contains a radiation-sensitive material (III) and colorant(s) (IV), comprising finely-divided pigment(s) and/or finely-divided powder(s) with dissolved dyestuff(s). (I) contains and (III) is a light-sensitive dihydropyridine cpd. or light-sensitive system contg. a hexaarylbisimidazole cpd. and a dihydropyridine cpd. or a thioamide or thiolactam. USE/ADVANTAGE - The process is useful for making colour proofs, esp. multicolour negative colour proofs with overlapping coloured areas, since it does not entail transfer of exposed areas or other intermediate stages. It is also suitable for making multicolour positive colour proof

Title: Splittable needle
Inventor: HEILIGER RAYMUND DR
IPC: A61M25/06
Filed: 1993-05-19
Granted: 1994-09-15
Abstract: A needle for introducing a catheter is splittable so that it can be removed after the catheter has been inserted. The needle 1 has two longitudinally extending notches on opposite sides thereof which allow the needle to be split into halves. The already pre-split ends of the needle are inserted into a sleeve 2 which can also be split into two longitudinal halves by means of grooves 3, 4. The splitting process is initiated by moving two fins 8 projecting radially from each half of the sleeve towards one other. After a partial splitting of the sleeve along the groove 3 one or more projections 9 on the fins meet and continued movement of the fins towards one another causes the sleeve to split along groove 4. The sleeve, and the needle with it, can thus be split using two fingers of one hand and in a single movement. <IMAGE>

Title: Method of production for a bit-line contact hole of a memory cell
Inventor: MELZNER HANNO DIPL PHYS
IPC: H01L21/768
Filed: 1993-09-08
Granted: 1994-10-20
Abstract: In the case of a memory cell having a stacked capacitor and a bit-line (14) arranged thereover, the bit-line contact hole is produced so that it self-aligns with the capacitor (7, 8, 9), it being possible completely to dispense with a photographic technique. The topography which is due to the capacitor is exploited for producing a contact-hole etching mask (12) by preferentially oxidising the upper parts of the cell plate (9). <IMAGE>

Title: Two-stroke internal combustion engine with closed charge cycle
Inventor: UFERMANN RUEDIGER
IPC: F02B75/02
Filed: 1993-09-15
Granted: 1995-01-19
Abstract: The arrangement shows a two-stroke engine design with closed charge cycle, that is exhaust port (8') and transfer port (6') are closed whilst the inlet port (13') is open and vice versa. As a result, the engine power, which depends crucially on its degree of scavenging, is substantially increased. In addition, due to the fresh charge method of the pistons (2, 2' and 3, 3') residual gases are removed from the combustion chamber (7') so that less fuel is needed. A fuel-air mixture in the space (10) can be led through the inlet port (9) so that due to the positive pressure of the piston (3') it arrives in the combustion chamber (7) in gaseous form by way of the port (11 and 12). As a result, a recharging with forced gas or fuel-air mixture transport is at the same time achieved, which has a positive effect on the running performance and the combustion characteristics as the load changes. The pistons (2 and 3) are air-cooled by the continuous fresh air supply. <IMAGE>

Abstract: Изобретение относится к иммунологии и касается переноса биологически активного соединения, преимущественно антигена, в организме животных. Эффективное количество биологически активного соединения заключают в микрокапсулы из биосовместимого индифферентного материала. Размеры микрокапсул не превышают 10 мкм. Вводят эффективное количество этих микрокапсул преимущественно перорально иммунизируемым животным. В качестве материала для микрокапсул обычно используют биологически активный полимер или сополимер, обладающие способностью проходить через желудочно-кишечный тракт или локализоваться на поверхности слизистой оболочки. При этом микрокапсулы не подвергаются биодеградации или подвергаются ей в незначительной степени. Это обеспечивает перенос биологически активного соединения на пейеровы бляшки или другие ассоциированные со слизистой лимфатическое ткани. Микрокапсулы включаются в них без потери активности и в количествах, достаточных для стимуляции системного иммуногенеза или иммунной реакции слизистых. Благодаря пульсирующему высвобождению агента индуцируется системный иммунитет и активируется иммунная система слизистых оболочек. 2 с. и 14 з.п.ф-лы, 1 ил., 19 табл.
