Title: Process and apparatus for controlling the aging process of foods, in particular raw sausage
Inventor: SCHULDT PETER DIPL ING
IPC: A23L13/70
Filed: 1984-01-30
Abstract: A process and an apparatus for controlling the aging process of foods, in particular raw sausage (11) are specified, in which water is removed from the material (11) to be treated in the treatment room (10) by the supply of possibly conditioned air (41) until the desired degree of maturing and drying is achieved. During the treatment, the temperatures in the treatment room (10) are continuously measured and compared with predetermined preset values (22) of temperature. Depending on an overshoot or undershoot of the predetermined temperature preset values, the temperatures in the treatment room (10) are returned to the predetermined temperature preset value. The temperature preset values themselves are controlled in relation to the course of the weight change of the material (11) to be treated. This weight change is continuously monitored via a measuring device (12, 21) and entered into the temperature controller (22) for the temperature preset values. <IMAGE>

Patent DE-3423342-A1 (DE)
Title: Apparatus for transferring at least one flexible line
Inventor: FALKENHAIN GUENTHER
IPC: H02G11/02
Filed: 1984-06-25
Abstract: For transferring at least one flexible line between a component which can be turned and a component which is fixed in relation to the latter, an intermediate storage arrangement is proposed, which has winding cores which are arranged parallel to one another. The first winding core is stationary and the second winding core is arranged so as to be rotatable about the first winding core, while turning around its own axis, in planetary fashion. The second winding core is rotatably connected to the shaft of the component which can be turned, without there being a difference in the rotary movement. Furthermore, the second winding core is kinematically connected to the first winding core, with a transmission ratio which corresponds to the ratio of their circumferences. The flexible line is, starting from a hollow shaft of the component which can be turned, carried parallel to the rotary connection arrangement between the said component and the second winding core up to the second winding core, wraps around the latter, is then guided up to the first winding core, wraps around the first winding core as well and is guided onwards by the wrap-around end there. The apparatus is particularly well suited for transferring glass fibre cables, which pose problems when passed through slip ring arrangements.
Patent DE-3424385-A1 (DE)
Title: Fluid friction clutch
Inventor: HAUSER KURT DIPL ING
IPC: F16D35/02
Filed: 1984-07-03
Abstract: A fluid friction clutch comprises a working chamber which is formed by an output component, in which an input disc connected to the driven component can rotate and which can be filled with a fluid taken from a reservoir chamber in order to set the degree of coupling, the reservoir chamber being designed as a pressure chamber and communicating with the working chamber via a pipe, a hole or the like. This hole is designed in such a way that fluid can be pumped out of the reservoir chamber into the working chamber by pressurising the said reservoir chamber with compressed air. A fluid friction clutch of this kind has no moving mechanical valve parts and this is advantageous in particular if the pressurisation of the reservoir chamber with compressed air is effected in a pulsed manner, something which leads to rapid wear in the known embodiments.

Title: Double twisted cell display device
Inventor: CREMERS ROLF
IPC: G02F1/1347
Filed: 1984-10-23
Abstract: The aim is to design a double twisted cell display device (1) so that it can be manufactured as a mass-produced item in a technically robust fashion, and can also be used as a particularly high-contrast, multiplexible matrix display device (1) with optional operation in negative or positive contrast representation. For this purpose, a molecule rotation by an angle of up to 90 DEG  is performed twice in the optical series circuit of the cells (8-9) from the polariser (4) to the analyser (6) without electrical control and accompanied by mutually parallel molecule orientation on the two-sided orientation layers (13''/13''') of the thin separating plate (7) separating the two cells (8-9) from one another. The thin information cell (8), which is fitted with segmented electrodes (10), is optimised for a rapid electrooptic reversing response. The thicker absorption cell (9), which is located in front thereof, is optimised by means of dye additives (15) for minimum residual transmission, and can be switched electrically via large-area electrodes (11) between negative contrast representation and positive contrast representation. The high response rate of the information cell (8) can be furthered in the case of low temperatures by electrical heating of the adjacent, large-area electrode (11) ...

Title: Optical aiming device for missiles which fly at high speed
Inventor: DUFRESNE DE VIREL FRANCOIS
IPC: G02B23/14
Filed: 1984-11-30
Abstract: The optical sight device makes it possible to increase the optical transmission quality by avoiding the formation of turbulence within the field of view at high speeds. A deflection device for deflecting the air flow striations (2) is arranged within the zone where turbulence can be formed and has a profile (2a) in the form of a post in order to repel the air flow striations laterally. In the case of a transparent flat wall (V3) through which the visual detection in this zone extends, the deflection device may consist of an attached plate (2), which is joined to the wall (V3) or is arranged in its vicinity.   The invention can be used especially on sight devices which are carried on board within a dome, in order to improve the sight detection to the rear. <IMAGE>

The fluid system (1) comprises a plurality of chambers (3) arranged one after the other, in the flow direction, and on top of each other in order to form a cascade (2), internal revolution streams (10) being generated within said chambers. The method is characterized in that the internal revolution streams (10) are exclusively or mainly generated by at least one material which, due to its lift, rises locally in the fluid system (1), or due to at least one material stream locally injected into at least one chamber (3). The device is characterized in that elements for guiding the stream are comprised of upwardly inclined guiding surfaces (9) in the direction of openings (12) through which the main material stream circulates and which interconnect the chambers (3) in cascade (2).
Patent DE-3502635-A1 (DE)
Title: Suspension apparatus
Inventor: VORINGER KONRAD
IPC: E04B9/22
Filed: 1985-01-26
Abstract: An apparatus is proposed which permits the suspension of ceilings made up of square or rectangular insulating panels which have a groove along two edges, abutting at a panel edge, and a tongue along the two other edges. In a known manner, the apparatus has a thin U-bracket which engages in a precisely fitting manner about the tongue, over the depth of the latter, fits into the groove and is provided with a fastening strap which is connected to one of the bracket legs and by means of which the apparatus can be fitted on the system of binders and joists. The fastening strap of the known apparatuses has to be pushed into the foam panel material. This presents difficulties for mounting and the panels are often damaged to an inadmissible extent. This disadvantage is eliminated according to the invention by a special configuration of the bracket 11 and of the fastening strap 12b and by a particular method of fastening the latter on the former. Furthermore, the centring of the panels during assembly is improved as a result. <IMAGE>
