Title: Process for the thermal preservation of foods
Inventor: SCHULZE-WITTEBORG WILHELM
IPC: A47J27/04
Filed: 1986-12-18
Abstract: The invention relates to a process for the thermal preservation of foods, in which the foods situated in a vessel (1) are heated up to a boiling temperature and then cooled, the vessel being sealed against the entry of air during the cooling operation. In order to accelerate the preservation operation during this known process, the invention proposes that the foods in the vessel (1) are steamed from below until most of the steam fed escapes from the vessel (1) at the top and that the vessel (1) is then air-tightly sealed. <IMAGE>

Title: Projection device for parallax panoramagrams
Inventor: BOERNER REINHARD DIPL ING
IPC: H04N13/349
Filed: 1987-01-08
Abstract: It is intended to improve the image quality in the outer panorama fields and in the lateral edge zones of the lenticular projection screen (PS) in large-surface, three dimensional multi-perspective representation of images in such a way that they can be perceived without optical aids. The lenticular projection screen (PS) is bent in the horizontal in circular shape (bending radius: Rs), the lenses of the projectors (P1, ..., P6) are to be arranged on a surface of a cylindrical casing (bending radius: Rp) and the thickness of the projection screen (PS) must be increased somewhat towards the side edges. For technical production reasons, this is more advantageous than varying the refractive index or the lenticular dimension of the cylinder lenses over the width of the screen. Beam-geometric correction of lenticular projection devices. <IMAGE>

Patent DE-3706750-A1 (DE)
Title: Textile machine
Inventor: FOTOURI SAEID
IPC: D04B39/06
Filed: 1987-03-03
Abstract: A textile machine for the production of sheet-like textile structures has a needle cylinder (24) which is driven in rotation and on which a ring of axially oriented needles (26) is arranged. The needles (26) are individually movable and controlled by stationary systems (16). Located above the needle cylinder (24) is a sinker cylinder (28) which is driven in rotation in the same direction and on which a ring of thread guides and/or sinkers (30) is arranged. A number of threads (42) is transferred to the needles (26) via these and shaped to form various textile structures. In a development of a circular knitting machine to form a combined circular knitting and weaving machine, the sinker cylinder (28) can be adjusted in a controlled manner by predetermined angular amounts in the circumferential direction in relation to the needle cylinder (24). The needle cylinder (24) and sinker cylinder (28) consequently do not run perfectly in synchronism. A cam mechanism (78, 82, 96, 98) can serve for their relative adjustment. Extended possibilities for the design of textile structures and patterns are thus obtained. <IMAGE>
Patent DE-3712011-A1 (DE)
Title: Device for preventing undesired moisture formation in buildings
Inventor: KREIENBAUM THEODOR
IPC: F24F3/14
Filed: 1987-04-09
Abstract: Particularly during the cold season, undesired moisture formation in buildings may lead to damp patches and mould fungus on walls and ceilings of rooms. Electrically operated air dehumidifiers are disadvantageous on account of their dependence on the mains and their wear. The novel device is to work substantially independently of external energy and be as insusceptible to faults as possible. A cooling medium extends between the room air and the colder outside air. In this case, the moisture of the room air condenses on a surface, cooled by the medium, inside the room. The condensation water is led away. The medium can be circulated as a fluid in two containers inside and outside the room or inside one container which extends between the room and the cooler outside environment.

Title: Shock wave source with short focussing
Inventor: REICHENBERGER HELMUT DIPL PHYS
IPC: G10K11/30
Filed: 1987-08-19
Abstract: The invention starts from a device for the contactless crushing of a concrement (22) present in the body of a living being (23). A shock wave source (18) generates essentially level shock waves (p) which can be delivered to the concrement (22) via a coupling medium (35). An acoustic focussing device (20) focusses the shock waves (p) onto the concrement (22). According to the invention, the focussing device comprises a convex focussing liquid lens (20) having an inlet wall and an outlet wall (12, 66; 24, 62) between which there is a liquid (31) that readily conducts shock waves. This permits a large apex angle (alpha) with comparatively little attenuation. <IMAGE>

Title: Method for the destruction of foam
Inventor: MIETH HANS OTTO DIPL ING
IPC: B01D19/02
Filed: 1988-02-04
Abstract: The invention relates to a method for the destruction of foam, in particular in the case of methods for separating off gas from milk and delimiting amounts of milk, having a process device, which is continuously or discontinuously charged with an electrically insulating process medium which forms foam in the course of its processing treatment, and having a spatially concentrated microwave field for the dielectric heating of electrically insulating materials. By means of the proposed method it is possible to destroy foam by an effective heating of a locally narrowly restricted region without projections extending into the foam being required and without the extent of the foam being enclosed. This is achieved by process engineering by, inter alia, exposing the space above the liquid interface of the foaming process medium, including the liquid interface, to the spatially concentrated microwave field (Figure 1). <IMAGE>

Title: Process for the preparation of an organic/mineral fertiliser
Inventor: HEINZE GERALD DR
IPC: C05D9/00
Filed: 1988-05-06
Abstract: The invention relates to a process for the preparation of an organic/mineral fertiliser from farmyard manure and inorganic substances which are mixed with each other and granulated. The farmyard manure can be solid or liquid. The addition of the inorganic substance, which must be soil-friendly and environmentally friendly, allows the abovementioned types of manure to be shaped by a granulation step so that they can be handled easily. Moreover, this measure results in a series of advantages, for example reduced malodour, prevention of the pollution of water courses by washing the manure away from the surface, better utilisation of the nutrients in solid or liquid manure, and, finally, reduction of the nitrate which would otherwise get into the groundwater.
