Patent DE-4221433-A1 (DE)
Inventor: KUESTERS KARL HEINZ DIPL PHYS
IPC: H01L21/8242
Filed: 1992-06-30
Abstract: The storage arrangement has DRAM storage cells in which the capacitor is arranged above the transistor and above the bit line (stacked capacitor above bit line cell). According to the invention, the cell essentially has self-adjusting contact holes for the connection of a capacitor plate (19, 33, 40) and the bit line (16) to the transistor (45). Thereby, and through the planarisation before the contact holes (12, 13) are made, the bit line (16) can be produced on a reltively flat surface. The capacitor may be a flat type or, to increase the capacitance, take the form of a dish or comb-shaped capacitor. The storage matrix of the invention with corrugated word lines reinforces planarisation and minimises the space required.

Title: Control for hot water circulating pump - has sensors for input temperature and input pressure to pump and with microprocessor control to prevent cavitation
Inventor: KWON YOUNG-SUK
IPC: F24D3/02
Filed: 1993-01-12
Abstract: The hot water system has a circulating pump (1) to move the water between the reservoir and the system. The inlet (2) of the pump has monitors for temperature and pressure. The values are digitised and processed by a microprocessor to generate control signals for the pump. If the pressure/temperature values fall outside programmed levels then the pump is stopped and an alarm operated. The system detects the onset of cavitation and prevents the pump from operating below its programmed level. The minimum inlet pressure for the pump, corresponding to particular temperature provides a reference value for the control. ADVANTAGE - Improved protection for circulating pump, failsafe operation of closed heating system.

Title: Process and equipment for producing liquid nitrogen
Inventor: SKOLAUDE WERNER DIPL ING
IPC: F25J3/04
Filed: 1993-02-09
Abstract: The process and equipment are used for producing liquid nitrogen. Air (1) is separated by a two-stage low-temperature rectification in a rectification system which contains a pressure column (4) and a low-pressure column (5). At the top of the low-pressure column (5), a gaseous nitrogen fraction (11, 12) is obtained and warmed in a main heat exchanger system (2). In addition, a liquid nitrogen fraction (20) is taken off from the rectification system essentially under the pressure of the low-pressure column (5) or under a higher pressure and passed to a storage tank (24). This storage tank is under a lower pressure than the low-pressure column (5). The liquid nitrogen fraction (20) is expanded upstream of the storage tank into an interposed separator (21) which is operated under a pressure which is lower than the pressure of the low-pressure column (5) and slightly higher than the pressure in the storage tank (24). The flash gas (22) formed during the expansion is warmed by indirect heat exchange (2). The fraction (23) which has remained liquid during the expansion is passed into the storage tank (24). <IMAGE>

Title: Motor-vehicle exterior rearview mirror
Inventor: LOTT THOMAS DIPL ING
IPC: B60R1/074
Filed: 1993-08-14
Abstract: The proposal is for a motor-vehicle exterior rearview mirror which serves for observing the terrain behind the vehicle. The motor-vehicle exterior rearview mirror comprises a base part which is fixed on the vehicle body and on which a mirror carrier is articulated and can be brought closer to the vehicle body, and distanced from the latter, by turning it around the upright hinge pin which is essentially parallel to the mirror plane. For this purpose, the motor-vehicle exterior rearview mirror has a driving device with an electric motor and a step-down gear, and, to limit the turning movement in the operational position of the mirror a stop on the mirror, carrier comes to rest on a counter-stop which is preferably connected to the mirror base. A motor-vehicle exterior rearview mirror which is particularly compact and can be fitted in a simple manner results if the step-down gear has a gear element which is held releaseably with respect to the mirror base and on which the counter-stop is formed. <IMAGE>
Patent DE-4331943-A1 (DE)
Title: Supercharging system for air-compressing internal combustion engines
Inventor: NEITZ ALFRED ING GRAD
IPC: F02B37/013
Filed: 1993-09-21
Abstract: The invention relates to a supercharging system for air-compressing internal combustion engines. Internal combustion engines with exhaust turbochargers have a tendency to so-called smoking when rapidly revved-up, since the exhaust turbocharger, owing to its inertia and insufficient exhaust gas energy, does not deliver sufficient charge air. This deficiency is remedied according to the invention in that two exhaust turbochargers (2), (3) are provided, connected in series, through which the exhaust gas flows. A control valve (6) is first closed, so that the outlet of the turbine (4) is connected to the inlet of the turbine (5). The first exhaust turbocharger (2) is of larger design and when the internal combustion engine is being revved up the flow passes through it without any great pressure drop, so that at first the greater part of the pressure difference benefits the second exhaust turbocharger (3) downstream and the latter delivers sufficient charge air into the charge air line (12) even at partial load. As the internal combustion engine is revved up further, the control valve (6) is switched over by means of accelerator pedal (16) and a control element (8) in such a way that the outlet of the turbine (4) of the first exhaust turbocharger (2) is directly connected to the surroundings, so that the second exhaust turbocharger (3) is bypassed. The second exhaust turbocharger (3) thereby already delivers a certain charge air pressure when idling and at partial load, for which reason, as revving continues, the first exhaust turbocharger (2) can be run up essentially faster owing to the increased exhaust gas energy. <IMAGE>

The component, e.g. table leg is folded against the outer edge of the table top. Pressure exerted by the thumb for example onto the pressure pin and pressure pin spring removes the closure piece in the hole out of the cavity (8) and releases the axle.

Patent DE-4345008-A1 (DE)
Inventor: POIER BRUNO
IPC: B62M11/02
Filed: 1993-12-30
Abstract: The invention relates to a drive for two-and three-wheeled vehicles which are operated preferably by muscular power via a rotational movement by means of chains on the drive wheel, for example a bicycle. This object is achieved, according to the invention, in that the crank arms are guided separately but are logically connected to each other in such a manner, via a bottom-bracket bearing gear, that a larger angular speed results for the backwards-running pedals than for the forwards-running, power-loaded pedals. This measures allows just the backwards-running pedals to pass rapidly through the dead zones and the sectors associated with poor efficiency. The pedals hence pass quickly back into the main angular zone of the drive, specifically at an instant in which the pedal which has been forming the drive up to now is just leaving this main angular zone of the drive. <IMAGE>
