Title: Rotary-screw compressor with overflow control
Inventor: SEIP RAIMUND DIPL ING
IPC: F04C28/12
Filed: 1987-03-12
Abstract: The invention concerns an automatically controllable rotary-screw compressor with a ribbed rotor (main rotor) and a grooved rotor (secondary rotor) located in the working chamber. In order to provide closed-loop control of the rotary-screw compressor by simple design, with a good control characteristic curve, low power requirements in the part-load range, and the possibility of sparing the drive motors by reduced-load starting, it is proposed that at least one screw rotor (6, 7) have an axial hole (16) with channels (18, 31, 32, 33) running radially from it and ending in the compressor chambers. A sealed piston valve (20) connected to the screw rotor (6, 7) that can be shifted along the axis is to be located within the axial hole (16); it has a travel (19) that is limited by two end positions (21, 22), corresponding to opening and closing of the overflow cross-sections of the channels (18, 31, 32, 33) located in the area of the end wall (9) of the high-pressure side. <IMAGE>

Patent DE-3805442-A1 (DE)
Title: Process for the conservational treatment of wax seals and apparatus for this
Inventor: KRAFT CHRISTIAN
IPC: C11B15/00
Filed: 1988-02-22
Abstract: Wax seals which have become brittle and wax seals which have taken in water require conservational treatment. Until now there has been no treatment process suitable for this. For the conservational treatment of wax seals, it is now proposed for the freely suspended wax seal which is to be treated to be heated slowly, while under subatmospheric pressure to be set, to a temperature below the melting temperature of the wax, to keep it limited to this temperature and subsequently to cool it slowly to room temperature. This is a successful way of making seals which have become brittle solid again and of drying out seals which have taken in water, so that the treated seals are subsequently virtually in their original condition again.

Title: Device for dewatering on a twin-wire former
Inventor: BUBIK ALFRED DR
IPC: B01D33/04
Filed: 1988-05-05
Abstract: An extended dewatering (drainage) foil (3) is installed along a first wire (5) of a twin-wire former. The foil has a liquid-accepting space (2), which is formed or left free between one part of the surface (4) facing the wire and the wire (5). Along the other wire (6) is arranged at least one adjustable foil (7), which is displaceable in the direction of the space (2). The space (2) has a profile which optionally increases in the running direction (arrow) of the wires. By pressing the foil (7) against the space (2) of the extended foil (3), the profile of the space (2) can be shaped, by which means the suction and, respectively, the liquid acceptance capacity of the space (2) is controlled. The attainable goal is to obtain a continuous suction effect increasing in the running direction. In so doing, undesired pressure impulses are largely avoided. The dewatering device is simplified and in consequence clearer. Dewatering proceeds gently, by which means the retention of fine particles in the material layer between the wires is increased. <IMAGE>

Title: Method and circuit arrangement for establishing frame synchronisation in a time-division multiplex system
Inventor: WAIBLE HANS-PETER DIPL ING
IPC: H04L5/22
Filed: 1988-09-30
Abstract: For time-division multiplex frame structures previously used, an imitation frequency of less than one per frame can be calculated for a predetermined frame alignment word (12 bits). Assuming a frame structure which is built up with octets, an imitation frequency of greater than nine per frame is obtained for an 8-bit frame alignment word. It is the object of the invention to establish fast and reliable frame synchronisation for such frame structures having an imitation frequency of greater than one. For this purpose, all bit patterns which correspond to the frame alignment word are first determined in a search mode for the duration of one time frame, and an information item on their position in time is in each case stored. In a following comparison mode, it is determined for the duration of the next time frame, in each case at the times stored, whether a frame alignment word is again present. The respective yes/no result is evaluated for establishing frame synchronisation. <IMAGE>

Title: Data compression on character basis for external memories of computers
Inventor: PORTUGALL HERIBERT
IPC: H03M7/30
Filed: 1988-11-08
Abstract: My idea is, for a specified selection of characters, which include, for example, text data, to use fewer memory positions per character than the eight positions (bits) which are specified by the manufacturer and supported by the computer. At the same time, using my method, repetitions of successive characters with the same bit code are combined. I have implemented all this in a method which I have specially developed, using control circuits. I have also succeeded in holding more characters in five bits than the number of different combinations of five bits (which can be compared to switches connected in series) allow. The same codes are used for different characters, but become unambiguous again with the help of the control information. The saving which is achieved, which is at least three bits per character including the elimination of redundancies, generally occupies only 60% to 20% of the original memory space on the external storage media for the same quantity of data. Conversion to this code from a humanly readable code, and vice versa, is done using a computer program, which can be converted for all computers which are currently on the market, independently of language. Existing compressions now only combine redundancies, or analyse repetitions of character sequences and combine them into a shorter code. My idea, which ... Original abstract incomplete.
