Patent DE-4304203-A1 (DE)
Title: Built-in-between cooking hob (cool top platform) with removable frame
Inventor: DITTRICH HARTMUT DR
IPC: F24C15/10
Filed: 1993-02-12
Abstract: The invention relates to a built-in-between cooking hob (cool top platform) with a removable frame. The built-in-between cooking hob is mounted so as to be able to be lowered with respect to the worktop. In the invention, the set problem is to develop a built-in-between cooking hob with a frame, in the case of which repair work can be carried out on a built-in-between hob without entirely dismantling the same and also a trouble-free exchange of the cooking hob is possible in situ, while at the same time the frame should be produced simply and inexpensively. According to the invention, the solution to the problem ensues from the fact that the built-in-between cooking hob possesses a removable frame which surrounds the glass-ceramic cooking zone in at least two planes and is connected thereto in the lateral region either from above visibly or invisibly. The frame can be drawn out, as required, forwards and/or upwards and the heating elements located below the cooking hob are thus exposed. The simple form of the frame allows inexpensive production, since finishing work in the form of grinding and polishing is not required. Similarly, this work on the chassis is dispensed with, since all of the parts are concealed by the frame.

Title: Hydraulic press with shortened work time - with valve unit to control fluid flow during pressure build-up
Inventor: BRECKNER MANFRED
IPC: B21D26/02
Filed: 1993-04-17
Abstract: Hydraulic system for pressing workpieces (11) comprises a pressure transfer device (10) having a housing (11), a first piston (12) which divides the housing (11) into two pressure chambers (13,14), both chambers being connected to a pressure source (15). The other side of the piston has a rod (25) whose work surface (26) is smaller than that of the main piston (17). This surface makes a work area (27) for the hydraulic fluid and as it moves forward it builds up pressure. The novelty is that a valve (35) is present which connects the two chambers (13,14) during pressure build-up until a certain pressure is achieved or the piston (12) has moved a certain distance. During this time fluid flows from (14) to (13). ADVANTAGE - The valve enables short work times to be maintained and therefore economic production together with a high degree of security.

Patent DE-4325037-A1 (DE)
Inventor: LANDMANN ANDREAS
IPC: B01D65/02
Filed: 1993-07-26
Abstract: Process water recycling plant, in particular for a damping solution and other process waters from printing machines. Process water is taken from a process water unit (B1), independently of its connection to the printing machine, and separated into filtrate and concentrate in an ultrafiltration filter (F2). The filtrate is recirculated via a process water recirculation line (22) into the process water unit B1. The concentrate is recirculated via a fluid line (18) a plurality of times into a working vessel (B3), through which the process water is also passed on its way from the process water unit (B1) to the ultrafiltration filter (F2). After reaching a certain concentration, the concentrate is taken from this filter circuit, chemically worked up, and separated into a solid phase to be removed and a liquid phase recirculated into the filter circuit. Since the recycling process operates separately from the process water feed to the printing machine, interference with one another is ruled out. <IMAGE>

Title: Process for the preparation and the use of monoclonal antibodies against X or Y chromosome-containing sperm for separating spermatozoa
Inventor: DITTRICH WALTER DR
IPC: C07K16/18
Filed: 1994-09-26
Abstract: Rapid and efficient separation of intact male and female sperm is desirable and necessary in many areas. The success of this has been only inadequate to date. Rapid and reliable separation of intact sperm is possible using monoclonal antibodies with selective specificity either for male or female spermatozoa. By using a ring-like pessary coated with monoclonal antibodies, parents are able to determine freely the sex of their offspring and need no longer leave this to chance. Furthermore, in agriculture it is possible before the artificial insemination of cattle, pigs etc. to separate the sperm rapidly and reliably into male and female spermatozoa.
