Title: Fast response AGC HF amplifier - maintains constant level using regulating capacitor between control input and reference potential
Inventor: BOCK RUDOLF DIPL ING
IPC: H03G3/20
Filed: 1990-06-21
Abstract: The amplifier is used for amplification of HF signals to obtain a constant given signal anplitude. It comprises a regulated amplifier stage (2) with a regulating capacitor (C) between its control input (3) and earth and a rectification diode (D) for the amplifier output coupled to the control input via an amplifier (7). The diode output is also fed to a comparator (8) for comparison with a reference voltage (UR) to provide an output signal when the rectified output signal amplitude is above the reference voltage. This output signal controls a switch (6) for switching the control input (3) between a voltage source (VCC) defining the max. amplification and a resistor (5) coupled to earth. ADVANTAGE - Rapid regulation preventing oscillation.

Title: Shock absorber closing appts. - has holder to take the assembly while tool bends over the top lip of the outer tube to close the end
Inventor: ITZINGER HERMANN
IPC: F16F9/32
Filed: 1991-04-20
Abstract: The appts. to close a piston/cylinder assembly, such as a shock absorber, has a holder to take the outer tube (3) of the absorber assembly at a defined position to a reference plane (20). At least one bending tool (17), to bend over the upper lip of the outer tube (3) of the assembly to form the closure, is moved from a radially outer position to bring the tool surface (19) parallel to the tube and against it. During the lip bending action, the tool (17) swings round a pivot point by a given angle between the end face of the piston and the tool surface (19). The mechanism gives a relative rotary movement between the outer tube (3) and the tool (17) while the upper lip of the tube (3) is bent over to give the closure. At the end of the lip bending action, the tool (17) is returned to its start position. ADVANTAGE - The appts. gives an effective closing action to the end of the tube contg. the shock absorber assembly, where the shrouding tube has a relatively thick wall, to give a flat closed end.

Filed: 1991-05-27
Abstract: In a drying process for improving the filling capacity of tobacco material, the cut and humidified tobacco material is conveyed in a stream of drying gas, dried within a tubular drying section and then separated from the drying gas. At a point where it is charged into the drying section, the drying gas has a temperature of at least 200 DEG C and a flow velocity of at least 30 m/sec. The flow velocity of the drying gas is reduced in the drying section. The flow velocity of the drying gas is in this case at most 100 m/sec at the point where it is charged into the drying section. Within the drying section, the flow velocity of the tobacco material is also reduced along with the reduction in the flow velocity of the drying gas in order to reduce the local heat transfer coefficient and the local mass transfer coefficient between the surface of the tobacco material and the surrounding drying gas. At the end of the drying section, the drying gas has a flow velocity of at most 15 m/sec and a temperature of at most 130 DEG C. <IMAGE>

Title: Narrow band size selection of ultrafine particles - formed by laser ablation, for deposition or detection
Inventor: GAERTNER GEORG DR
IPC: B22F9/12
Filed: 1991-06-03
Abstract: Narrow band size selection of ultrafine particles, generated from a solid target by a laser beam, is effected by transferring the particles in a carrier gas stream to a region in which unipolar charging of the particles occurs and then transporting the particles through an aperture into the capacitive field of an electric selector and/or the magnetic field of a magnetic selector having parameters selected to cause beam splitting in the interesting particle size range so that a very narrow band particle size distribution is obtd. at a detector or substrate. USE/ADVANTAGE - The process is useful for selection of 1-10nm. dia. particles of free, deposited or matrix-embedded materials for use e.g. as phosphors, nonlinear optical materials, cathodes, miniature information stores, quantum dots, ductile ceramics, ultra-high resolution light sensitive films, metallic particles embedded in oxide (for nano-size electrical conductivity phenomena or percolation effects), magnetic recording materials, and catalysts.

Each line is connected not only via a first network (16 or 17) to a coating chamber (15) but also via a corresponding second network (8 or 9) to each anode (5 or 6). The coupling (10) between the coil (19) and first line (20) is connected to the cathode of a rectifier diode (26) whilst the anode of (26) is connected to the coupling (11) between the capactor (18) and the second line (21). Both cathodes (1,2) are operated with a free performance ratio. ADVANTAGE - During the coating process using magnetron sputtering source in reactive atmosphere arcs disappear or the tendancy for arcs to appear is reduced.

Patent DE-4213259-A1 (DE)
Inventor: KOLBINGER JOSEF
IPC: H04J3/14
Filed: 1992-04-22
Abstract: A method and a circuit for monitoring digital periodic signals (for example PCM 30) is specified by means of which the fault finding and error detection in systems having such signals is simplified. This is done in such a manner that the bit pattern of the first signal period (frame) within an observation period is stored and the bit patterns of the following signal periods are compared with the bit pattern of the first signal period. When a deviation occurs, the corresponding bit is recorded in a deviation memory. At the end of the monitoring period, the deviation memory, together with the stored bit pattern of the first signal period, provide information on the variation of the input signal. <IMAGE>
