Patent DE-4224590-A1 (DE)
Inventor: SCHNAKENBURG JOACHIM VON DIPL
IPC: B22D11/04
Filed: 1992-07-22
Abstract: A mold for horizontal continuous casting of steel to form large-format slab cross sections, particularly flat products, includes a water-cooled metal casing forming the mold cavity for a slab and a brake ring for the melt feed which is supported at the mold on the pour-in side and connects the mold with a melt supply vessel (distributor) via a connecting casting tube. In order to provide an inexpensive and particularly stable mold, the mold is closed on the pour-in side by a metal plate along a part of the free cross-sectional area of the mold cavity. The plate has one or more openings for receiving a break ring. An end plate which overlaps the metal plate is arranged in front of the metal plate in surface contact with the metal plate. The end plate is provided with openings which coincide with the openings in the metal plate with respect to position and number. Ducts for guiding cooling water are incorporated in the end plate.

Abstract: Steel is continuously cast with a solidus-liquidus interval greater than 55 deg.C and casting cross section smaller than 300 mm x 300 mm. The casting after exit from the mould is cooled in a secondary cooling zone. Casting parameters such as the overheating temp., casting velocity, and the length and intensity of the secondary cooling are jointly adjusted so that along a cooling section (14) bounded by the liquidus point (13) and the solidus point (15) for the centre of the continuous casting, the ratio of the cooling rate of the casting surface to the cooling rate of the central casting core is at least 0.4 (0.45-0.1). Pref. the casting parameters are adjusted so that, at the end of spray cooling, the liquidus point (13) for the centre of the casting is located within a diagram region where the casting surface is reheated during air cooling. Alternatively, these parameters are adjusted so that the liquidus point (13) is located in a region where the casting surface has reached the max. reheating temp. (7') or begins to fall again. USE/ADVANTAGE - Used in the metallurgical industry. It prevents C segregation and occurrence of cavities and/or internal cracks in the centre region of continuous castings with a small cross section.

Title: Method of speeding up the data processing of a signal processor
Inventor: WITTE FRANZ-OTTO DIPL ING
IPC: G06F7/57
Filed: 1993-02-12
Abstract: The invention concerns a method of speeding up the data processing of a signal processor, to a signal processing unit (10) of which input data (EA; EB) with n-bit word length is fed. The signal processing unit (10) contains at least an arithmetic unit (14) and a multiplier (12). With such a signal processor, if input data words (EA, EB) with a shorter word length than the maximum n-bit word length of the signal processor are provided by a source for processing, invalid bits must be masked out during loading. This operation, and bit manipulations with other masks, can be speeded up if the content of the input data words can be changed by at least one masking unit (44, 54), which can be preset, depending on its setting, before processing by the signal processing unit (10). <IMAGE>
Patent DE-4305928-A1 (DE)
Title: Device and method for cooling liquid and gaseous media by means of air
IPC: F15B21/0423
Filed: 1993-02-26
Abstract: The invention relates to a device and method for cooling liquid and gaseous media by means of air, in particular an air-oil cooler for stationary and mobile hydraulics. Known devices and methods of this state of the art have problems with the rotating air turbulence produced by the fan. This air turbulence produces friction and reduces the flow velocity of the air and thus the efficiency of the device. The invention provides a remedy here by one or more webs (5) being arranged between the cooler (1) and the fan (2) in such a way that they divide the air-conducting cross-section into two or more chambers (16, 18), as a result of which rotational air turbulence is largely reduced. <IMAGE>

Inventor: SIEBERT MARTIN DIPL ING
IPC: B29B17/02
Filed: 1993-10-31
Abstract: Sepn. of thermoplastic parts (2) from a continuous flow and sorting mixts. of different thermoplastics makes use of the differing softening points of the materials. The plastic parts (2) are heated to a specific temp. relative to the plastic material to induce softening and the continuous flow (5) is compressed by an external force which causes varying deg. of deformation according the plastic type. The change in surface area is then utilised to separate off specific parts or materials.  Process appts. comprises two rotating rolls (6b) with elastic faces through which the parts or materials are passed. The softened plastic enlarges in area during passage of the nip between the rolls (6b).
