Patent DE-4135326-C1 (DE)
Title: Coating components by thermal spraying - using preheating kiln to heat workpiece before plasma spraying in vacuum chamber
IPC: C23C4/137
Filed: 1991-10-25
Granted: 1993-06-09
Abstract: To coat components by thermal spraying, esp. vacuum plasma spray at preheated components to a given temp., the workpieces are preheated by heat radiation and/or convection in a kiln with induction or electrical resistance heating. The component workpiece is pref. initially heated and the component and/or kiln are moved so that the workpiece is in a defined position for the next stage. The workpiece is placed in the preheating kiln in the cladding position, and, after heating, the kiln is retracted to clear the workpiece for deposition. The workpiece is in the same position for preheating and deposition. USE/ADVANTAGE - The process is for coating components, e.g. turbine blades, where a layer is deposited on the substrate material. The method gives an effective bond between the substrate material and the deposited layer, without imposing stresses on the workpiece which could lead to cracks or other faults.

Title: TV amplitude modulator circuit with constant carrier phase - uses fast switching 5 nano-second FET, high speed operational amplifier and band-pass filter or frequency converter stage
Inventor: BSCHOR WALTER DIPL ING
IPC: H03C1/36
Filed: 1992-04-24
Granted: 1993-09-30
Abstract: The AM modulator consist of a fast operational amplifier (1) with a fast switching FET (4) with its source (s) connected to the op-amp inverting input (2). The non-inverting input (3) is grounded. A feedback resistor (R2) is connected between the amplifier output (6) and the inverting input. A square-wave signal at the carrier frequency, for example a TV IF signal is applied to the FET gate input (8). The modulation input signal (7), e.g. a video baseband signal, is input via a resistor (R1). The amplifier output signal is passed to a band-pass filter or a frequency converter stage. The filter suppresses unwanted spectral components, e.g. part of the upper sideband. In operation the FET resistance switches between 40 ohms and greater than 10<8> ohms. The input and feedback resistances are selected for a gain of 1 when the FET is ON. USE/ADVANTAGE - TV modulator circuits with constant carrier phase and good linearity at frequencies up to 100 MHz. switching time is independent of modulation level, and carrier phase in modulated signal is constant.

Granted: 1994-08-18
Abstract: The invention relates to a wire section of a paper machine with two endless wires (mesh belts) (2, 3) - a first wire (2) and a second wire (3) - which together form, on a part of their periphery, a double-wire zone; having at least one supporting body (1), arranged in the region of the twin-wire zone and having a supporting surface, at least a part of the supporting surface supporting the first wire (2) on its inner surface and the second wire (3) on its outer surface. Pressure elements (10) exert pressure on the inner surface of the second wire in the region in which the latter is supported by the supporting surface, the pressure elements bringing the pressure to bear only at specific points (pressure points), so that pressure-free regions also remain. The pressure points are distributed over the whole wire width. The supporting bodies (1) are designed as a forming cylinder (1a) or belt (1c). The supporting surface formed by the latter preferably rotates. Rails (foils, strips) (10), roll doctors (14) or concavely designed pressing shoes (15) can be used as pressure elements. <IMAGE>
