Patent DE-4326605-A1 (DE)
Inventor: STEIN JUERGEN DR ING
IPC: B03B5/60
Filed: 1993-08-07
Abstract: Method and device for separating a fine-grained solid into a fine material and a coarse material at a separating grain size below 50 mu m, preferably below approximately 10  mu m. The aim of the invention is to indicate a method and a device which, in an economical manner, make possible a clear separation in particular in the grain size range below approximately 10  mu m. To achieve this aim, the fine-grained solid is dispersed in a liquid which can form drops and the dispersion is forced into a defined sink flow with a superimposed rotation flow generated independently of the sink flow. The ratio of the speeds of the sink flow and the rotation flow determines the separating grain size. Serving as the device is a rotary-driven deflector wheel with blades running parallel to its axis of rotation and forming flow ducts, which is flowed through from the outside to the inside and to which the solid dispersion is fed at the external circumference. <IMAGE>

Patent DE-4340590-A1 (DE)
Inventor: CHIU KUANG Y
IPC: H01L27/088
Filed: 1993-11-29
Abstract: A P-type substrate 16 is immersed in a solution of potassium hydroxide (KOH) which etches exposed portions of the substrate to form trenches 14 with sidewalls 30 at an angle of 54.7 degrees with respect to the top surface of the substrate. A vertical boron implant is then conducted which implants boron ions into the angled sidewalls of the trenches. A layer of oxide 54, is then deposited over the substrate surface to fill the trenches approximately flush with the surface of the substrate. NMOS transistors may then be formed in the islands surrounded by the trenches so as to be isolated from other NMOS devices. The boron doping of the sidewalls prevents the inversion of the sidewalls due to any charged contaminants in the deposited oxide. This avoids parasitic leakage currents between the N-type source and drain regions of the NMOS transistors which abut the sidewalls of the trenches. <IMAGE>

Title: Interruption-free power supply for electronic circuits
Inventor: ABERT MICHAEL DIPL ING
IPC: H02J9/06
Filed: 1993-12-16
Abstract: A bus system (BL) has two power supply rails (VS1,VS2) for 5 and 0 volts. A mains unit (NT) provides 5V. Semiconductor circuits (ST1,ST2) control switches (S1,S2) coupled to batteries (B1,B2) via diodes (D1,D2). Battery voltages can be switched through to a common line (BAT) that supplies memory circuits. If the mains voltage unit output is greater than the battery voltage, the line receives its supply via a diode (D3).Voltage monitoring stages (K1,K2) provide inputs to the control circuits to ensure that an empty battery is signalled and a change-over made to the other. LED indicators (LED1,LED2) signal that a change in battery is required.

Title: Exhaust gas equipment for at least one IC engine of ship

IPC: B63H21/32
Filed: 1994-02-04
Abstract: The equipment has a ball floater valve (6) connected between an outlet aperture (4) of the exhaust gas pipe conduit (3a) and the exhaust silencer (2) in the exhaust gas pipe conduit at a level above the cut-off component (5). The ball (6a) of the floater valve is so dimensioned that on the one hand its drive on the rise of outside water in the housing (6b) of the floater valve is ensured so that an adequate closing pressure occurs against the pressure of the exhaust gas even at full load of the engine (1), and on the other hand a low throttling of the exhaust gas during normal operation of the engine is guaranteed. The exhaust gas cooling device is so formed as a closed heat exchanger so that the walling of the exhaust gas conduit is flowed through by cooling water from the outlet aperture as far as the floater valve.
Patent DE-4403541-A1 (DE)
Title: Stud welder
Inventor: BREITBARTH ACHIM
IPC: B23K9/20
Filed: 1994-02-04
Abstract: A stud welder has a device to guide studs into the head ready for welding from a store. There is a sensor in the store which detects the presence or absence of a stud in the delivery position. The sensor signal goes to a control unit.  Once a bolt has been found to be in the delivery position, the control unit sends out a transport signal so that the bolt moves to the welding position. When a certain time has passed after a transport signal has been released, an error signal is generated if the sensor has not detected another stud in the delivery position.

Title: Safety valve
Inventor: ILLIUS HERBERT
