Title: High energy capacitor e.g. for linear accelerator - uses electro-restrictive or piezoelectric material as dielectric with temperature held to value around Curie temp. point
IPC: H02N2/18
Filed: 1991-08-09
Abstract: The high energy capacitor uses an electrorestrictive or piezo-electric material as a dielectric (4). This is sandwiched between two metallic electrode plates (6,8) with outer blocks (M1,M2) of metal. A hydraulic unit is used to apply mechanical forces (K1,K2) to the blocks to charge the capacitor. The electrodes can be connected to an external electrical load, such as a linear accelerator. When the electrical circuit is closed an electrical oscillator is imposed upon the mechanical element and this oscillates. The temperature is controlled (S) to a value around the Curie point. ADVANTAGE - High current, high voltage fast response device.

IPC: B29C48/08
Filed: 1991-08-14
Abstract: Prodn. of a light-conducting strip (I) by encasing optical fibres in UV-cured resin (II), bonding several parallel sheathed fibres together with a UV-cured adhesive (III) and curing the adhesive. Optical fibres are encased in (II) under an oxygen-contg. gas. Pref. (I) is a flat strip contg. 3-32 sheathed fibres; (II) is cured by UV irradiation under inert gas (nitrogen, argon etc.) contg. 1-8 vol.% oxygen, to provide an oxygen-inhibited surface layer which bonds more strongly with (III); pref., (II) and (III) consists of similar material (esp. urethane-acrylate, polyester-acrylate, polyether-acrylate, silicone-acrylate). USE/ADVANTAGE - Adhesion between (II) and (III) is improved if the fibres are coated with (II) under oxygen-contg. gas instead of inert gas, giving a strip (I) of improved mechanical strength. In an example, polycarbonate fibres (dia. 0.5 mm) were coated with a 15 micron layer (II) by passing through a mixt. of 50 pts.wt. urethane-acrylate (obtd. by reaction of 500 g propanediol/PO polyether, 167 g 2-hydroxyethyl acrylate, 0.5 g Desmorapid SO (RTM), 0.3 g p-methoxyphenol and 265 g IPDI, 50 pts.wt. 2-(N-butylcarbamoyl)-ethyl acrylate (IV) and 3 pts.wt. 2-hydroxy-2-methyl-1-phenylpropan-1-one (V) (photoinitiator) at 30 m/min. and UV-curing with a medium-pressure Hg lamp (120 W/cm) in an atmos. of nitrogen contg. 4 vol.% oxygen; 3 coated fibres were then combined and passed through a ring nozzle together with an adhesive contg. 50 pts.wt. polyester-acrylate (from reaction of 500 g OH-contg. linear neopentyl glycol polyadipate, 40 g acrylic acid, 2 g p-toluene-sulphonic acid, 0.3 g p-methoxyphenol and 0.3 g di-tert.-butylhydroquinone), 50 pts.wt. (IV) and 3 pts.wt. (V), and the combination was cured with UV. Non-sticky 3-fibre strip was obtd., which required a large force to pull the individual fibre apart by hand (cf. little force required if (II) was cured in the absence of oxygen).

Inventor: DOETSCH WINFRIED
IPC: C02F11/13
Filed: 1992-02-25
Abstract: To reduce the liquid content of a mixture of solids and fluids, the mixture passes through a contact dryer (1) at the first drying stage (TS1) into an intermediate stage (ZWS) to be compressed into bodies. The compressed material is carried by an enclosed conveyor (10) to the dryer (11) of a second drying station (TS2), to be dried to the final moisture content level. Heat from the drying action in the first stage (TS1) is used to heat the dryer (11) of the second stage (TS2). Also claimed is an assembly with a contact dryer (1) outlet leading to a press section (8) for the material. An enclosed conveyor system (10) leads to the entry of the second drying stage (TS2) dryer (11). The vapour from the contact dryer (1) of the first drying stage (TS1) heats the heat carrier medium for the dryer (11) of the second stage (TS2) or acts as the heat carrier medium for the dryer (11).4 USE/ADVANTAGE - The system is for the disposal of sewage sludge, and also waste from concentrated seepage water, manure, or waste from the chemical mfg. industry, and other mixtures of solids and liquids.

Title: Blow moulding for a rubble chute segment - uses a prepared blank with an inner relief contour within a mould.
Inventor: SCHMITZ EGON
IPC: B65G11/08
Filed: 1992-10-28
Abstract: The blow moulding action, to form inner contours in hollow bodies of malleable plastics material, uses a hose-shaped blank with a relief inner contour with a smaller cross section than the final hollow body and with a wall thickness and inner contour thickness greater than in the final body. The softened blank is placed in one of the outer moulds and closed at both sides.

Patent DE-4236547-A1 (DE)
Inventor: BEHRENT HERMANN
IPC: H04B1/30
Filed: 1992-10-29
Abstract: The invention relates to a homodyne receiver, particularly for angle-modulated carrier signals, in which the converted signal (ZF) exhibits a direct-voltage component (DC component), and a method for correcting the converted received signal. In homodyne receivers, essentially three groups of errors are produced. The DC offset, the amplitude difference and the phase error between the I and Q branch. Normal regulating processes of the local oscillator with PLL fail in the case of weak signals. To use inexpensive and fast A/D converters, the DC offset, in particular, must be separated. In as much as this has been done previously and the I and Q signals were also corrected, these corrections could only be achieved with expensive components in the RF group. To avoid this, a processor is provided which is constructed for recalculating the ellipse spanned by the distorted I and Q signals into a circle. The ellipse parameters are determined, in particular, by means of a compensating calculation over at least five sampled values of the I and Q signals. The errors causing the ellipse shape are then calculated from the ellipse parameters and compensated for. <IMAGE>
