Title: Method and apparatus for producing a fibre strand in the tobacco processing industry
Inventor: HENSGEN GERHARD DIPL ING DR IN
IPC: A24C5/34
Filed: 1988-05-13
Abstract: An apparatus is described for producing a tobacco strand for the production of cigarettes. A tobacco strand (2) is sprinkled on a strand conveyor (1) and conveyed in the direction of the longitudinal axis, surplus (8) being removed by means of a surplus removal device (7). Upstream and downstream of the surplus removal device (7), the density of the strand is measured by IR light barriers (16, 17), and the removal of the surplus is controlled as a function of the density signal obtained on the equalised tobacco strand (2a) downstream of the surplus removal device. The quantity of surplus (8) removed is determined by means of a belt weigher (28) and a surplus signal (Ü1) is generated. As a function of this surplus signal (Ü1), the density signal (D2.1) is corrected so that undesirable influences of additional strand properties, such as the colour of the fibre, on the density signal are eliminated. <IMAGE>

Title: Recording and playback amplifier arrangement for the video heads of a head drum
Inventor: REIME GERD
IPC: H04N5/91
Filed: 1988-06-28
Abstract: Connected to the interconnection (10) of the series circuit of the fixed windings (8, 9) of the rotating head transformers (6, 7) of the head drum (3) of a video recorder and to the external terminals (12, 13) of this series circuit (8, 9) are three recording amplifiers (15, 16 and 24) of which the output (20) of the recording amplifier (15, 16) which is connected on the output side to the external terminals (12, 13) of the series circuit (8, 9) is connected to one output (21) of a phase reversal stage (22), and the input (20) of the third recording amplifier (24), which is connected to the centre terminal (10) of the series circuit, is connected to the other, antiphase output (23) of the phase reversal stage (22). This circuit arrangement produces at the fixed windings (8, 9) of the rotating head transformers a video signal which controls the video heads (1, 2) and whose amplitude is virtually twice as large as the absolute value of the operating voltage (UB) of the operating voltage source (27) supplying the recording amplifier. There is thus no need for the voltage supply of the recording amplifier to have an additional operating voltage source with an operating voltage which is higher with respect to the operating voltage for the supply of the remaining circuits of the video recorder. <IMAGE>

Title: Device for conveying a flat object
Inventor: KOEPPE WALTER
IPC: B65H23/038
Filed: 1989-02-09
Abstract: A description is given of a device for conveying a flat object, especially an endless material web (13), which has conveying means (39) for moving the object in a predetermined direction. The position of the object (13) transverse to its conveying direction is monitored by means of a monitoring device (37) designed as a pneumatic measuring barrier (41). For this purpose, a stream of a gaseous medium is directed through a blast nozzle from a pressure source (46) onto the edge region of the surface of the object. The proportion of the gas stream flowing past the edge is detected by a pressure measuring means (42b, 52) as a measure of the position of the edge. In the case of deviations of the position of the edge from its desired position, a guide roll (16b) mounted on a pivoting frame (53) is adjusted transversely to the conveying direction of the object (13), so that the object once again reaches its desired position. This web edge control is of particular advantage in all material web guiding in which precise maintenance of the position of the material web is concerned. <IMAGE>

Patent DE-3908435-A1 (DE)
Title: Water fitting
Inventor: HENKE GUENTER
IPC: F16K47/02
Filed: 1989-03-15
Abstract: In a water fitting, a valve body (16) is constructed on a manually longitudinally displaceable, spring-loaded push-rod (8). To avoid pressure impacts upon closure of the valve (13, 16), the push-rod (8) has a damping piston (15) for a damping chamber (12). Deposits in the latter are avoided by virtue of the fact that it lies in the water path between the inlet (2) and the outlet (3). During the closing movement (Z), the damping piston (15) blocks the damping chamber (12) on one side. Also lying in the water path is a pipe section (14) which is assigned a limiting piston (17) arranged on the push-rod (8). During the closing movement (Z), the limiting piston (17) forms with the pipe section (14) a displacement gap (18) through which the damping piston (15) pushes water out of the damping chamber (12). <IMAGE>

Filed: 1989-03-20
Abstract: Installation for continuous production of monoglycerides of fatty acids, in particular glycerin monostearate, by transesterification of triglycerides and glycerin or by esterification of fatty acids with glycerin, in a sealed reactor. To obtain an end product with a lower acid number, the installation comprises a degassing container (1) which removes water vapour from the reaction mixture, a device (11) for controlling the level in the degassing container and a valve (8) coupled with the device at one of the outlets of the degassing container. The invention also concerns the corresponding process for continuous production of monoglycerides of fatty acids. To solve the above-mentioned problem, the water vapour is removed from the reaction mixture by degassing even before the reaction is complete. This is achieved by separating the reaction mixture into a vapour phase and a liquid phase within a given residence time.

Title: Process for the preparation of compost
Inventor: STRATMANN GOTTFRIED
IPC: C05F17/00
Filed: 1989-04-15
Abstract: The present invention relates to a process for the preparation of compost by biodegrading untreated organic waste material, in particular organic waste material from refuse collections, in which process the waste material to be composted is arranged in the form of a clamp in a biodegradation chamber or the like where it is converted into compost under the action of aerobic microorganisms, the clamp being formed in such a way that waste material is dumped at the beginning at the front end of the chamber, the clamp is gradually turned over in longitudinal direction to the chamber towards the back end of the chamber, and fresh waste material is constantly supplied at the front end of the chamber, the organic waste material being composted without previous comminution. Preferably, the organic waste material is pregraded in a grader prior to processing, and all treated organic materials are separated out, whereupon the untreated organic waste material is composted essentially without comminution. The advantage of the process is, inter alia, that costly disposal of the expressed water (press water), which is obtained in the usual compacting step, is dispensed with. <IMAGE>
