Title: Stacking device for printed sheets - has suction head attached to piston of power cylinder to grip individual sheets
Inventor: STEIGERWALD STEFAN
IPC: B41F15/12
Filed: 1991-06-21
Abstract: A printing machine, and in particular a silk-screen printing machine, is provided with system for arranging the printed sheets in a stack.

Patent DE-4225967-A1 (DE)
IPC: C02F3/34
Filed: 1992-08-06
Abstract: An oil/water emulsion, in particular from car wash installations, if required after elimination of sink material and freely separating light liquid in a buffer tank (3) designed as a preliminary separator (2), is subjected to a sequential biological purification ("SBP" process) by microorganisms in a vessel (9) with charging, mixing and aeration phases in such a manner that, independent of the influx of the emulsion to the buffer tank, the charging of the vessel and the concentration of the emulsion are kept as constant as possible and in a composition as favourable as possible for the nutrition of the microorganisms. For this purpose, nutrient salts containing nitrogen and/or phosphates and carbon-containing substances as supplemental nutrient can be added (17-19) to the emulsion as additional nutrients for the microorganisms. As a result, it is possible to use the "SBP" process with car wash installations even in the case of unbalanced nutrition of the microorganisms and frequently highly irregular influx, without having to fear damage to the population of microorganisms. <IMAGE>

Title: Glass droplet feed - uses valve action of plunger and vessel wall to give variety of droplets in a compact assembly
IPC: C03B7/084
Filed: 1992-08-08
Abstract: In the glass droplet feed, for high glass temp. ranges and low number of cuts, the contact surface stability is achieved by the valve closing action between the plunger (1) and vessel wall (2), free of hydrostatic pressure from the column of molten glass over the valve point (1,2), but which is used for the molten glass flow for the next droplet when a formed droplet has been delivered The plunger (1) takes up a position within the vessel wall which allows molten glass to flow through by the different dias. between them, to build up the contact surface back formation (10-11), by simultaneous reclosing until the shape (11) is formed and the stabilising frequency (12) is restored. USE/ADVANTAGE - The method is for the prodn. of glass droplets of individual character. The system gives a small and compact appts. which produces a variety of glass droplets.

Title: Integrated circuit tuner for HF superheterodyne receiver - derives sampling signal for phase=locked=loop from common VHF-UHF amplifier output connection within IC
Inventor: USHIDA SUSUMU
IPC: H03J5/24
Filed: 1992-09-10
Abstract: The IC tuner converts HF signals, from VHF or UHF band, to IF signals. A phase-locked loop sampling signal is taken from the output of a VHF amplifier (7) or UHF amplifier (11) instead of directly from a resonant circuit, and is amplified (20) before being applied to a PLL circuit (18) via a balanced-to-unbalanced convertor (22). This arrangement eliminates the VHF PLL amplifier conventionally used between the VHF resonant circuit (16) and the PLL circuit, and safeguards stability of the resonance. USE/ADVANTAGE - In VHF or UHF band, PLL amplifier can be eliminated from peripheral circuits without detriment to oscillation stability.

Filed: 1992-10-18
Abstract: The distn. tower, is composed of two vessels, a heat exchanger, and units to hold, feed and pump the material, a processing medium and processing matter to separate the high percentage of water from the oil. The two vessels are in a vertical stack, with a contents level sensor at the lower vessel, linked to a pump at the holding tank to deliver oil to the lower vessel as required. The heat exchanger unit is within the lower vessel with overheated water to give the evapn. temp. The temp. is controlled by regulating the water feed through a valve, esp. motor driven operated w.r.t. the temp. registered by a thermal probe within the lower vessel. Pref. an outlet at the upper vessel which acts as an expansion vessel to take the vapour from the lower vessel, leads to a heat exchanger, to give prim. and sec. cooling to convert the vapour wholly into water to be collected in an auxiliary tank. USE/ADVANTAGE - The appts. is used in large steel and metallurgical installations, where there are large quantities of soluble oil to be handled. The appts. gives a simple, efficient and economic distn. tower. It may also be used in the dehydration of industrial emulsions, residues from sugar cane or sugar beet or in alcohol distse
