Patent DE-4113708-A1 (DE)
Title: Electronically switchable LC resonant circuit arrangement - has supplementary capacitor connected in parallel to existing LC circuit by diode and transistor switch
Inventor: ERAT AUGUST DIPL ING
IPC: H03J5/24
Filed: 1991-04-26
Abstract: The resonant circuit (C3, L1) incorporates a supplementary capacitor (C1) connected to earth via a diode (D1) and a high frequency coupling capacitor (C2). When a voltage is applied to the base of an NPN transistor (T1) across a resistor (R4), the voltage drop from the potential divider (R1, R2) forward biases the diode, connecting the supplementary capacitor to earth via the diode and coupling capacitor and via the transistor. When the voltage is removed from the base of the transistor, the diode ceases to conduct, effectively removing the supplementary capacitor from the resonant circuit. An additional high-value resistor (R3) ensures that a positive voltage is present on the transistor collector at all times. ADVANTAGE - Low impedance add-on circuit only marginally affects Q-factor of resonant circuit, while circuit switching is effected by application of simple positive voltage.

Inventor: SCHOLL HANS JOACHIM DR
IPC: C08G18/79
Filed: 1991-05-28
Abstract: Fluid and storage-stable organic isocyanates containing carbodiimide and/or uretonimine groups are prepared by partial carbodiimidisation of isocyanate groups with phospholine-type catalysts, after which the carbodiimidisation reaction is stopped by adding a silylated acid of the formula X-[Si(CH3)3]n, in which 
 
  X represents the neutral acid radical as it is obtained by removal of the acidic hydrogen atoms from an n-basic acid having a pKa value of not more than 3, with the exception of hydrohalic acids, and 
  n represents an integer from 1 to 3. 
 
<??>These polyisocyanates are used for the preparation of polyurethane plastics.

Abstract: The invention relates to a mechanism for letter files, having a baseplate (10), two sorting pins (12) which project vertically above the baseplate, a folding bar (18) which is limitedly pivotable between an open position and a closed position, a spring (24) which is tensioned on the baseplate (10) and acts against a bend (26) in the folding bar with prestress in the direction of the open position, and an actuating lever (22) which is mounted pivotably on an end shield (20), which is fixed to the baseplate, and acts against the bend (26) in the folding bar (18). In order to achieve a spring characteristic which is favourable for the opening and the closing operation whilst maintaining an economic construction, the spring (24) is produced from bent spring wire which is tensioned at its two free ends (30) in bores (32) in the baseplate, and which has two torsional portions (34) directed towards one another from the tensioning point (32) and a curved bending portion (38) which is bent at the mutually facing ends (36) of the torsional portions (34) in the direction of the bend (26) in the bar and rests against the latter. <IMAGE>

Title: Fail-safe control valve for rear wheel steering - has limiters on full travel of proportional control valve to limit maximum flow rate of hydraulic fluid to steering cylinder
Inventor: NEUHAUS ROLF DR ING
IPC: B62D7/14
Filed: 1991-08-14
Abstract: The rear wheel steering is driven by a hydraulic steering cylinder (14) controlled by a proportional control valve (20) and an electronic processor (12). The steering is locked by electro-hydraulic clamps e.g. in the ahead position. The clamps have a set time delay and cannot fully protect against sudden steering deflections if a fault occurs. The failsafe control has stops to limit the travel of the proportional valve in either direction, thereby limiting the maximum fluid flowrate to the steering cylinder. The stops can be part of solenoid valve stops and comprise domed additions to the ends of the proportional valve pistons striking the solenoid stops in the ends of the cylinder walls. ADVANTAGE - Failsafe addition to steering.

Title: Linear approximation for use with outline fonts - determines number of curve sections from curve geometry to enable font generation time reduction
Inventor: TAKAHASHI SHINGO
IPC: G09G5/36
Filed: 1991-10-16
Abstract: The linear approximation method is for approximately printing a curve defined by two end points and at least one control point. It involves dividing the curve into a number of sections and joining adjacent sections via straight lines. The number of divisions is determined from the difference between two values corresp. to the sum of the lengths of lines from the end points to a point on the curve and the distance between the end points. The number of divisions is determined from areas (S2,S3) enclosed by straight lines joining the end points and the control point. USE/ADVANTAGE- For use with outline fonts, the linear approximation method can reduce the time required for generation of a font using an optimal number of divisions.

Title: Line signal coding method for synchronous digital transmission - interlacing bits or bytes of signal and polarity bit before coding
Inventor: URALA REINO
IPC: H04L25/49
Filed: 1992-01-24
Abstract: The line signal is formed from bytes containing a number of bits and is transmitted via a digital transmission signal using a clock which is synchronous with all multiplexed hierarchies. The bytes are formed such that a number of useful bits or bytes and additional bit(s) are interlaced in sequence before being coded. The additional bit is pref. a polarity bit which guarantees that at least one state change occurs per cycle. The line signal is coded such that the bit states of the useful signal are either unaltered when the polarity bit has one binary value, or inverted when the polarity bit has the other value. ADVANTAGE - Improved signal balance; allows increased clock speeds.

Title: Oil tanker with central tanks and rows of side tanks - has anti-corrosion coating on smooth inner tank walls, and tank lining to separate oil and ballast water
Inventor: PARASKEVOPOULOS GEORGE DIPL IN
IPC: B63B11/04
Filed: 1992-08-18
Abstract: The central tanks contain crude oil and water ballast. The inner tank walls (7,8) are smooth, and all necessary projecting construction parts are located in the side tanks. During construction, the smooth walls are primed with an anti-corrosion paint (9), and are then evenly coated with an "Elastic Anti Rust Composite Material" (10). This prevents corrosion by the ballast water. The central tank contains a plastic-rubber lining. This permits ballast water to be carried below and oil above it.

Title: Process for fully automatic fermentation process control in the production of alcoholic beverages
Inventor: LUEBBERT ANDREAS PROF DR RER N
IPC: C12M1/36
Filed: 1993-02-19
Abstract: Fermentation process control by means of indirect measured variables such as the carbon dioxide content of the fermentation vessel exhaust gas stream or fermentation vessel contents and control of the fermentation process according to a preset course of changes in temperature and pressure in the fermentation vessel are prior art. The object of the invention is an improvement of the fermentation process control with respect to simplicity and accuracy. This object is achieved by direct determination of the ethanol content in the fermentation vessel exhaust gas stream as an instrumentation parameter. Advantages of this solution result from the selection of a fermentation product other than carbon dioxide, that is ethanol, as an indicator of the fermentation process which can be measured and influenced accurately and simply. <IMAGE>
