Title: Appts. for regulating strip feed from coil into cold rolling stand - using signals relating to rate of rotation of feed-off coil and change in radius of coil
Inventor: GLEISSNER GERHARD DIPL ING
IPC: B21B37/54
Filed: 1989-07-28
Abstract: Apparatus for regulating the feedihg speed of strip entering the rolls of a cold rolling mill stand comprises a device (30-31) which regulates the rate of rotation of the feed-off coil (6) such that the entrance speed (VE) and leaving speed (VA) of the coil into and from the roll stand are synchronised with the roll gap dimensions. ADVANTAGE - The apparatus is technically simple and avoids prior art problems associated with non-synchronised feed-in feed-out speeds and roll gap.
Patent DE-3926964-A1 (DE)
Inventor: HAUPT GUENTHER DIPL ING
IPC: F01K23/06
Filed: 1989-08-16
Abstract: In plants with fossil combustion, carbon dioxide and, if appropriate, water are ultimately formed as a combustion product. These two products are as a rule released as waste gases into the atmosphere. The carbon dioxide produced then impedes the heat emission from our Earth and causes the so-called greenhouse effect. The invention is based on the object of largely suppressing the release of carbon dioxide from a gas-and-steam power plant into the atmosphere. In a gas-and-steam turbine power plant with a gasifier (18, 238) upstream of the combustion chamber (14, 234), it is provided according to the invention that the raw gas (RG) from the gasifier (18, 238) is dedusted, cooled, purified and enriched with water and shift-converted. The carbon dioxide (CO2) and, if appropriate, the sulphur compounds are separated off by a scrubbing agent. The carbon dioxide is disposed of, for example passed into a dry ice plant (66, 290) or otherwise industrially utilised. The pure gas (GG) largely free of carbon dioxide and containing essentially hydrogen is fed as fuel to the combustion chamber (14, 234) of the gas turbine. The invention is applicable especially to gas-and-steam turbine power plants, but can also be used in pure gas turbine power plants. <IMAGE>
Patent DE-3934947-A1 (DE)
Title: Maintaining filtrate pressure during reversed flow flushing - by simultaneous transfer of gradually accumulated filtrate
Inventor: FRIEDRICHS DIETER
IPC: B01D29/11
Filed: 1989-10-20
Abstract: During liq. filtration, a separate stock of filtrate is slowly built up. When the filter is cleaned by reversed flow of filtrate, pressure on the filtrate side is kept unchanged by a rapid transfer through the filter of this stocked filtrate during the brief reversed flow flushing. Material dislodged from the filter surface during reversed flow enters the slurry side, whose pressure is increased during the flushing by additional slurry supply. Slurry chamber and filtrate stock container may form part of a cylinder holding an axially mobile piston. The filter itself may have a metal net hose mounted on a protective basket, and dividing a tubular housing into chambers for slurry and filtrate. USE - For spinning and other processes where pressure drop on filtrate side can cause prod. deterioration.

Filed: 1989-11-08
Abstract: The hydropneumatic piston cylinder unit comprises a cylinder closed at one end (4), having a cylinder cavity (6) filled with an hydraulic medium.  Into this is inserted through the open end of the cylinder a piston (8) attached to a piston rod (12). The cylinder cavity is hydraulically joined to a pneumatic spring reservoir (9).  The piston is formed as a circumferentially seal-free immersion piston (30) within the cylinder cavity. USE/ADVANTAGE - Piston-cylinder unit for a vehicle shock absorber in which internal friction is kept to a minimum.
Patent DE-3940639-A1 (DE)
Inventor: APITZ SIEGFRIED
IPC: G11B15/18
Filed: 1989-12-08
Abstract: A video recorder with automatic still picture positioning senses during moving picture mode the levels of the waveform of the FM signal for successive fields and calculates a ratio from these levels. In still picture mode, the waveform levels are measured at respectively corresponding angular positions with respect to head switching pulses, and level ratios are likewise calculated. These actual level ratios are compared with set level ratios, as have been obtained from the moving picture level ratios in consideration of geometrical characteristics of the playback arrangement. From the deviations between level set values and level actual values, a respective tape position correction value is obtained. By constantly matching the level set values to the current ratios, it is ensured that the tape position correction values are appropriate for the current ratios. <IMAGE>

Title: Alternately operating regeneratable air-drying filters - for bleed pipe in large propellant fuel storage tank
Inventor: BACKHAUSS ROLF
IPC: B01D53/26
Filed: 1990-01-08
Abstract: Since the moisture content of air entering a fuel tank during filling and extn operations can produce long term deterioration, incoming air (35) is filtered by the silica gel (21) in one of a pair of units, with the transparent casing showing the progressive rise in collected moisture before the air enters a two-way valve (13). When the rising level reaches a sensor (27), the two-way valve is actuated to transfer entering air into the compression filter unit. A heating coil (33) in the first unit is taken to about 110 deg C to provide thermal regeneration of the first unit silica gel; thermal insulation protects the valve against transmitted heat. ADVANTAGE - Humidity, which can produce damage to engines esp of aircraft, is made too low to produce sludge. One filter is always operative.

Title: Needle valve for injection moulding machines - has needle at angle to valve axis to give clear polymer channel when open
Inventor: WOLFF HANS-MARTIN
IPC: B29C45/28
Filed: 1990-07-10
Abstract: An electrically heated needle valve has an essentially cylindrical melt channel running in a straight line along the valve axis. The bore for the valve needle runs at an angle to the axis through the valve housing and the cuff heater. When the valve is open the tip of the valve needle can be withdrawn completely clear of the melt channel. Pref. the valve body is enclosed in a cuff heater with heating elements embedded in a Cu casting. The valve needle moves in a guide tube which is welded or soldered to the valve housing and runs through the casting. In the open position the rounded tip of the valve needle is withdrawn far enough to be completely clear of the melt channel so as not to interfere with the polymer flow. USE/ADVANTAGE - The method avoids formation of residues which can cause contamination in subsequent operation.

Title: Ventilator wheel for three=phase alternator of motor vehicle - is made of metal plate with central disc part having outwardly extending blades with reinforcement seams
Inventor: RICCETTI FRANCESCO
IPC: H02K9/06
