Title: Camera having an automatic exposure unit and a lens diaphragm controlled thereby
Inventor: ROTH JOHANN
IPC: G03B7/085
Filed: 1982-07-17
Abstract: A camera having an automatic exposure unit and a lens diaphragm controlled thereby, preferably a two-blade shutout, is proposed, with the closing movement of which a grey filter is inserted into the taking ray pencil starting from a prescribed camera aperture in order to counteract the occurrence of defraction phenomena in a setting to small and very small camera apertures. The grey filter (24) is arranged on a separate carrier (23) and is functionally connected to the lens diaphragm in such a way that given a relatively large camera aperture it remains outside the taking ray pencil and given a relatively small lens aperture it penetrates into the taking ray pencil. <IMAGE>

Patent DE-3245620-A1 (DE)
Title: Screw press
IPC: B30B9/12
Filed: 1982-12-09
Abstract: A continuous process for draining liquids from raw material in a screw press having a spindle, the pressing section being divided into individual pressing zones. The pressing section is split at least into three separate pressing zones. The material for pressing, which runs through continuously, enters each pressing zone with virtually no pressure being applied each time and is compressed in each case only within the said zone. Upon transition into the following pressing zone, the material is rearranged and only then is it re-compressed. The pressing force required for the drainage is regulated by the back pressure. In a screw press for carrying out this process, there is provided behind a pressureless inlet zone a first drainage zone which is limited by a baffle plate and behind which adjoins at least a second drainage zone, likewise terminated by a baffle plate. Situated behind the last drainage zone is an axially adjustable closing cone behind which adjoins the outlet opening. For the purpose of rotating the screw, a toothed ring with inner toothing is connected to the screw. At least one motor-driven pinion engages on the inner toothing.

Patent DE-3408369-A1 (DE)
Title: Method of producing a rotary brush
Inventor: HERRMANN RUDI
IPC: A46D3/04
Filed: 1984-03-07
Abstract: A method of producing a rotary brush is described, which is simple and uncomplicated and with which rotary brushes can be produced, whose brush fitting is fixed on the surface of the core so as to be reliably secured against rotation. In a particularly preferred exemplary embodiment, the brush fitting for producing a large rotary brush is firstly arranged on a tubular core whose inside diameter exceeds the outside diameter of the machine shaft and the core and attachment rings are then jointly shaped into a polygon, preferably a rectangle. In this manner, the brush fitting is fastened to the core so as to be fixed against rotation in the circumferential direction. The gap between the inside diameter of the core and the outside diameter of the machine shaft is filled by a reusable adaptor which exhibits the bore for the machine shaft and whose outer surface is matched to the inner surface of the core of polygonal shape to transmit the rotary movement. In the case of small rotary brushes for hexagonal machine shafts, a core corresponding in its inside diameter to the outside diameter of the machine shaft and the attachment rings arranged thereon are shaped to be hexagonal.
Patent DE-3408993-A1 (DE)
Title: Subatmospheric-pressure homogeniser with reversible pressure reduction by barometric riser, ultrasonic assistance, expansion turbine and intermediate pressure increase with multistage construction
Inventor: HEYMANN BERNHARD
IPC: B01F5/06
Filed: 1984-03-12
Abstract: To improve the efficiency of the homogenisation, the static pressure upstream of the homogenising valve is reduced to a value close to the vapour pressure of the liquid. The pump is positioned downstream of the homogenising valve. The pressure reduction takes place in a barometric riser, and this pressure energy is recovered in a barometric downpipe. Only a small pressure difference is now required to generate cavitation. The energy requirement is thus considerably reduced, and it becomes possible to use centrifugal pumps. The result of the homogenisation can be improved by injecting ultrasound waves. The height of the construction can be reduced, if the input pressures are high, by an expansion turbine at the inlet, which is mechanically coupled with a pump at the outlet. In the case of multi-stage homogenisation, both in the subatmospheric-pressure and in the superatmospheric-pressure range, the energy requirement can be reduced by a pressure increase between the homogenising valves.

Title: Method for controlling the correction process for electronically controlled printers
Inventor: JANSSEN REINER DIPL ING
IPC: B41J29/373
Filed: 1984-06-16
Abstract: Strongly adhesive deletion tapes (45) have the tendency of remaining stuck to the recording medium (27) after the correction process. The invention is based on the object of making it simpler and less expensive, in comparison with the prior art, to release the adhesive deletion tape (45) from the recording medium (27). This is achieved according to the invention in that the type carrier carriage is moved, after each correction stroke, in the direction of transport of the adhesive deletion tape (45) in relation to the recording medium (27) in order to release the adhesive deletion tape (45) from the recording medium (27) and that, subsequently, the winding-on spool (49) is transported by means of an electromagnetic transducer, for example by the stepping motor (57). As a result, it is possible to make the electromagnetic transducer (57), constructed as a drive device, for transporting the adhesive deletion tape (45) less powerful than the known drive devices. This has advantageous effects for the manufacture of inexpensive small printers. <IMAGE>
