Title: Arrangement for the generation of a uniform brake pressure in two or more parallel hydraulically separated, brake circuits
Inventor: KLEIN HANS-CHRISTOF
IPC: B60T11/10
Filed: 1983-12-09
Abstract: An arrangement for controlling the brake pressure and for generating a uniform brake pressure in two or more parallel but hydraulically separated brake circuits essentially comprises a controllable valve (V1), for example an electromagnetically operatable multiway valve, in a first brake circuit (4) and a double hydraulically operated separating valve (TV2) in each of the other brake circuits (5). In the rest position, that is with the control inputs at zero pressure, the separating valve (TV2) is shut off. If, due to actuation of the controllable valve (V1) in the first hydraulic circuit (4), pressure (pA1) is also built up on the output of the valve, this leads by way of a control line (7), connected to the separating valve (TV2), to the separating valve being switched open. Should the first hydraulic circuit (4) fail, for example due to a leak, the closure of the separating valves is cancelled so that, under the effects of the hydraulic pressure (pE2) on the input (8, 8'), this is switched open. A particularly simple separating valve essentially comprises a hollow cylindrical housing (14) which is open on one end face (15) and closed on the other end face (16) except for a connecting aperture (17) and into which an insert comprising two diaphragms (20, 21, 21'), an adaptor (20) and an end piece (22) is introduced. An operating pin (23) arranged on the first diaphragm (19) ... Original abstract incomplete. <IMAGE>

Title: Method of making a concrete trench wall
IPC: E02D5/18
Filed: 1984-02-06
Abstract: To seal the construction joints between two adjacent segments of a trench wall, first of all an undercut longitudinal groove is produced in the joint face, e.g. by encasing a split tube (4) in concrete, when placing the concrete of a segment. A sealing strand (14) of elastic material is inserted into this longitudinal groove after pulling out the formwork element. The sealing strand (14) extends beyond the joint face with an extension part (17) which is encased in the following segment when the concrete of the latter is subsequently placed. According to the invention, during the concreting of a trench-wall segment, first of all only initial measures need to be taken for the subsequent installation of the sealing strand, which itself is pushed in only after the ground for the following segment is excavated. The risk of damage to the sealing strand during the excavation for the following segment is thereby removed. <IMAGE>

Title: Fuel rod spacer grid for nuclear fuel elements
Inventor: DEMARIO EDMUND E
IPC: G21C3/356
Filed: 1984-02-28
Abstract: The invention relates to a fuel rod spacer grid for nuclear fuel elements, consisting of interengaging grid strips (12, 20) which form between themselves grid cells (7) for accommodating the fuel rods. Projections (14a, 14b) formed on the grid strips (12, 20) serve to position the fuel rods in the grid cells (7), it being the case that in each grid cell the projections (14a) of two grid strips not opposite one another form a flow obstacle for the axial coolant flow, and that the projections (14b) formed on the two other grid strips essentially do not form a flow obstacle. When the fuel rods are seated loosely in the grid cells, the coolant flow then has the effect of pressing the fuel rods away from the projections (14a) forming an obstacle so that they make definite contact with the projections (14b) not forming an obstacle. …<IMAGE>…

Title: Self-propelled harvesting machine for sugar cane
Inventor: LEIGERS GUENTER
IPC: A01D45/10
Filed: 1984-08-08
Abstract: The present invention relates to a self-propelled sugar cane-harvesting machine having a compressed-air blower, the air stream of which is directed through the material stream, falling from the inclined conveyor band onto an ascending discharge conveyor band, towards the fall-out hood. This compressed-air blower is assigned in the upper inlet region, towards the fall-out hood, a suction-air blower which is located in the material stream and which is intended to assist the compressed-air blower. In order to prevent the material stream from building up in front of the carrier holding the suction-air blower, this carrier is designed as a hollow profile which, starting from the rotary hub, extends essentially opposite to the material stream or air stream and which forms with the air stream an acute angle always less than 55 DEG . This ensures that the holder is mounted or guided in such a way that it scarcely impedes the material stream.

Title: Coder/decoder for a digital data transmission system with an nB/(n+1)B line code
Inventor: HENTSCHKE SIEGBERT DR ING
IPC: H03M5/14
Filed: 1984-11-22
Abstract: It is intended to indicate, for a digital data transmission system with an nB/(n+1)B line code, a coder and decoder which have a simple circuit structure and are suitable for implementation in VLSI technology. The coder according to the invention operates as follows (and the decoder accordingly): an n-bit input word is inverted or not inverted and the inversion or non-inversion is characterised by an additional bit depending on which of these two measures leads to the operationally smaller accumulated disparity. An n-bit input word with a zero word disparity is not inverted, and the additional bit of the corresponding (n+1)-bit output word is used as a filler bit or for transmission of additional digital information with a low bit repetition rate. The decoder at the receiving end is synchronised by checking the code rule, an initial value of the accumulated disparity being set in a first stage and the position of the frame of the serial-to-parallel converter (40) connected upstream of the code converter at the receiving end being shifted in a second stage. This coder-decoder system (Fig. 1) is preferably suitable for processing parallel data streams, the parallel-to-serial converter (20) connected downstream of the code converter at the transmitting end operating as a multiplexer and the corresponding serial-to-parallel converter (40) at the receiving end operating as a demultiplexer.

Title: Process for fabricating galvanic patterns having vertical flank slopes and high aspect ratios in the sub- mu m region
Inventor: SCHNEIDER-GMELCH BRIGITTE
IPC: G03F7/09
Filed: 1985-01-31
Abstract: In order to fabricate galvanic patterns in the sub- mu m region, the electron beam-sensitive resist pattern (7, 7a) is generated on a layer system consisting of the combination of a first thin metal layer (6) which back-scatters electrons strongly, and therebelow a second metal layer (5) which back-scatters electrons weakly and can be converted into a metal oxide during etching. Between this layer sequence (6, 5), which preferably comprises gold and aluminium, and the plating layer (3) provided on the substrate (1) for the subsequent plating step, there is a polyimide layer (4) as an interlayer and electroplating mask. By employing this layer sequence (4, 5, 6, 7) it is possible to fabricate sub- mu m patterns having vertical flank slopes and high aspect ratios (up to 8:1). The process is used for fabricating masks in microelectronics, especially X-ray absorber masks. <IMAGE>
