Title: Plant setting machine - with plants removed from containers and loaded into plating feed by transfer mechanism which protect them unloading from containers
Inventor: STUEBER REINHARD
IPC: A01C11/02
Filed: 1989-12-22

IPC: B01D29/39
Filed: 1990-02-23
Abstract: A rotor filter press is described, in which filter discs 7 are placed on a carrier 13 and are penetrated by a shaft 3, a collecting tube 15 runs under the filter discs 7, which tube is connected in an attachable manner via a connecting piece 16 to an outlet orifice 17 of each assigned filter disc 7, and each filter disc 7 is divided into filter disc sectors 19, 20 and a lower filter disc sector 19 is provided with the outlet orifice 17, is separated from the shaft 3 by a distance 25 and the collecting tube 15 is pushed by means of a rotary movement between the shaft 3 and the carrier 13. It is required in this case that the installation and removal of the lower filter disc sector be simplified. This is achieved by every connecting piece being a connecting nozzle 16, over which the assigned lower filter disc sector 19 with the outlet orifice 17 is pushed along a drop distance, by the drop distance being adapted to the distance 25 between the lower filter disc sector 19 and the shaft 3 and by a ring segment 26 being pushed by means of a rotary movement about the shaft 3 between the shaft 3 and the lower filter disc sector 19. The lower filter disc sectors are pushed onto the connecting nozzles and the ring segments are pushed under the shaft. <IMAGE>

Title: Condensing ammonia, natural gas and fluoro-chloro-hydrocarbon(s) -  in simple washing-condenser plant, including prepn. for storage and transportation
Inventor: CURTIUS FRITZ
IPC: B01D5/00
Filed: 1990-10-18
Abstract: This is a method of condensing vapour from industrial process. By material exchange processes in a washing condenser where it is washed in counterflow with a fluid having a higher boiling points. the cold vapour is converted to the higher b.pt. vapour of the washing fluid. The cold vapour becomes liquified, and the vapour from the higher b.pt. fluid is liquefied in a heat exchanger. The heat exchanger can be installed in the vapour outlet pipe from the condenser. USE/ADVANTAGE - Used for the liquefaction of cold vapours such as ammonia, natural gas, and FCKW, and includes the cooling of pressing vessels in which the cold vapours are stored and transported, and also the evacuation of parts of the plant that contain these gases. The complications of earlier methods of condensing these vapours are avoided.

Title: Vehicle paintwork protective wax coating removal - by condensing vaporised spray media in spraying zone for simple fluid extn.
Inventor: FAHRENBERGER MARTIN DIPL ING
IPC: B05B16/00
Filed: 1991-01-31
Abstract: Vaporised solvent and/or washing media are sprayed in a closed environment, to be extracted and further condensed. The condensn. occurs in the spraying zone, to be extracted in fluid form without the passage of air. Pref. condensn. is at the walls of the spraying zone, where there is a water film over the walls running down, or the condensn. is at free water mists. Veils of water mist cover the entry and exit of the spraying zone, and also the sides and from below. The condensed vapour is extracted together with the water, and then sepd. conventionally and treated. Assembly has a system to extract the vaporised medium from the spraying zone and a condenser in the spraying zone. The extn. system removes the fluid. The spraying zone walls act as the condenser covered with a running water film. A free water mist generator also acts as a condenser, which is also used to cover the entry and exit and also form a water mist at the sides and from below. ADVANTAGE - Removed from the spraying zone more simply than in a pure vapour form

Title: Yeast dough prods. - made from fat-free base dough with all fat incorporated later, allowing prodn. of pastries, etc. without preliminary fermentation stage
Inventor: SPAMER HELMUT
IPC: A21D13/08
Filed: 1991-06-01
Abstract: In yeast dough prods., made by (1) forming a base dough from at least flour, yeast and liq., (2) incorporating fat by repeated turning and rolling, then (3) shaping to give an intermediate product for subsequent baking, the new feature is that practically no fat is present in the base dough but rather a correspondingly greater amt. of fat is introduced in step (2). Also new is prodn. of yeast dough baked goods by (1) slowly heating the unfermented dough product in a first low temp. range until the yeast have been killed then (2) finally baking at a second, higher temp. to produce a consumable prod. USE/ADVANTAGE - The method requires less equipment, energy and time than known processes (where the dough is allowed to ferment for 15-90 min before baking). Secondary raising (in the oven) is promoted so that a final product of high vol. and loose texture is produced. The intermediate dough prods. are easily handled for further process
