Patent DE-4236460-A1 (DE)
Inventor: ECKARDT HELMUT DIPL ING
IPC: G05D16/20
Filed: 1992-10-29
Abstract: A pressure controlling and/or regulating device (8) for a fluid medium, in particular air or gas, but preferably nitrogen, to be supplied besides the plastic molten mass to an injection molding tool, may be designed as a stationary, but preferably as a mobile unit, arranged between a pressure generator/accumulator (7) and an injection system associated to the injection molding tool (3), for example in a nozzle head or in a supplementary module. The device has a main line (21) that leads from the pressure generator/accumulator (7) to the injection system (27) and which can be switched by a valve control only between letting through or blocking the inflow of medium, a first bypass line (28) to a receiving side of a pressure sensor (29) whose other receiving side is sensitive to the medium pressure in the injection molding tool, and a second bypass line (30) which can be switched by a valve control influenced by the pressure sensor (29) between a letting through or a blocking state, forming an outflow of medium from the injection molding tool, in particular a medium return flow to the pressure generator/accumlator (7). The essential trait of this invention is that the main line (21) consists in sections of at least two parallel flow paths (23a and 23b); each flow path (23a and 23b) is equipped with a medium inflow control valve (24a and 24b) which can be selectively switched between a letting through or a blocking state, the medium inflow control valves (24a and 24b) have different openings (25a, 25b) and can be progressively switched individually and/or together between a letting through or blocking state depending on the pressure difference detected at the pressure sensor (29).

Title: Automatic sewing machine - has structured speeds for fabric holder drive along each axis using identified stitch data and pulses
Inventor: NISHIZAWA YOSHIFUMI
IPC: G05B19/416
Filed: 1993-04-07
Abstract: To control an automatic sewing machine, an actual stitch is identified within a given sequence of a number of stitches, and at least one set of pulses for the stitch gives drive commands to one step motor at at least a further set of pulses gives drive commands to a second step motor. The control from at least one of the first and second pulses reponds to the step, to identify the movement of the drive mechanism to give a speed less than the max. speed. Also claimed is an automatic sewing machine with a fabric holder and a twin-axis drive to move the fabric holder along one axis and independently on a second axis. A processor generates commands, stitch by stitch, according to the pattern with two sets of data to give the fabric holder movements along each other two axes, with a drive control to give movements at most at the max. speed. The control gives movement along each axis, slower than the max. speed, and computes a change point before the drive starts. USE/ADVANTAGE - The automatic sewing machinbe can be operated at higher speeds, with a twin-axis drive giving a linear movement to as required position without getting out of step to give improved working speeds and fitness for use.

Title: Method and arrangement for unambiguous allocation of measurement results in road traffic
Inventor: BEIER WOLFGANG DIPL ING
IPC: G08G1/04
Filed: 1993-05-28
Abstract: Technical problem: measurement results of measurements on multilane roads are intended to be allocated in an unambiguous manner to in each case one vehicle. Prior art: at the same time as the measurement, there is performed an optical detection (camera) which makes it possible to identify possible ambiguities. In the event of a possible ambiguity, the measurement results are not processed any further. Basic concept: use other measurements which do not give rise to the same ambiguities. Example: two intersecting measurement lobes, in each case across all the lanes. Advantages and disadvantages: twice as complex in terms of equipment, but two different kinds of measurements (toll collection, speed measurement) are possible as a result. <IMAGE>

Title: Automatic area feedback in optical 3D digitisers
Inventor: MASSEN ROBERT PROF DR ING
IPC: G05B19/42
Filed: 1993-10-17
Abstract: In order to transmit the large quantity of point coordinates such as arise when optically digitising models and shapes on CAD (computer-aided design) installations, these point coordinates must be traced back into polynomial areas. For this purpose, the points must be subdivided into practical regions which are each traced back to an area or an area lattice. The invention describes a method for optically marking these regions directly on the model to be digitised and for automatically identifying these markings from the two-dimensional image evaluation of an image sensor contained in or on the 3D measuring head. Linear and coloured, as well as two-dimensional and textured markings are particularly proposed. Appropriate selection enables the markings to be not only automatically identified but also automatically distinguished and, consequently, control information for the feedback methods to be identified automatically as well, separately for each area feedback.

Title: Device for redn. of vibrations in combustion chamber for gas turbine systems - has equal number of burners in flow direction of gases displaced by specific distance which is determined by formula
Inventor: FISCHER MELCHIOR DR
IPC: F23M20/00
Filed: 1993-10-22
Abstract: There is an equal number of burners (2',2") arranged in the flow direction of the gases. These burners are displaced in relation to one another by a specific distance ( delta s), the noise speed in the combustion chamber being greater than the hot gas speed. The specific distance by which the burners are displaced is represented by the following formula: - delta s = u(2n + 1)/2f where  delta s = the displacement of adjacent burners or groups of burners in the flow direction in m, u = the hot gas speed in m/s, f = the inherent frequency of the combustion chamber in 1/s, n = 0,1,2,3.... The adjacent burner groups consist of two burners. ADVANTAGE - Reduces thermal and acoustic disturbances and prevents thermo-acoustic vibrations in the combustion chamber.

Title: Multipart convertible sofa bed
Inventor: LIEBERKNECHT ARTHUR
IPC: A47C17/16
Filed: 1994-01-05
Abstract: In the seat position the seat cushion is spaced from the backwall (29). The backrest incline comprises a hinged flap part (31). The backwall is connected to the flap part at the top end by a connector (32) and at the lower end by a spacer strip (33). The backwall, flap part and spacer strip form a triangular hollow cavity filled up by a folding wall (38). The folding wall defines the distance through which the flap projects over the seat cushion height into the structural depth of the seat cushion. The angle between the flap part and spacer strip corresponds to the incline angle (43) of the backrest cushion. The spacer strip is connected to the flap part by a hinge (34) and can be folded upwards. The spacer strip engages in a support bearing (35). The distance between the seat cushion and backwall can be produced by spacer members (36,37).

The semiconductor arrangement has, for example, a plurality of bar-shaped trench recesses on the surface of a n-type semiconductor substrate which is arranged in strips and has a "U-shaped" cross-sectional shape. At least one n<+>-type source region is present on the surface and is sandwiched between the trenches. Insulated electrodes whose potential is set at that of the source region and whose conductive material is produced so that it has a work function such as to form a depletion region in the drain region are arranged around the latter in the corresponding trenches. The depletion layer acts as a barrier in order to make an electrical discontinuity between the source region and the drain region. A p-type injector region is also arranged on the surface of the drain region and touches each surface of the insulated electrodes, whose potential is fixed, at each edge of the bar and an arbitrary potential can be fed therein from outside. The potential of the injector region controls the potential on the surface of the insulated electrodes, which ... the ... Original abstract incomplete. <IMAGE>
