Filed: 1989-05-31
Abstract: The circuit arrangement consists of several part-circuit arrangements which in each case contain an analog multiplexer and an analog/digital converter and which are in each case followed by a register set. In this arrangement, the part-circuits can be mounted as close as possible to the sensor elements so that analog signals are only conducted via very short line sections. In addition, each analog/digital converter only has to convert a relatively low number of analog signals so that no excessive demands are made of the operating speed of these analog/digital converters.

Abstract: A centrifugal pump has a pair of separated sealing arrangements (A1, A2) enclosing a sealing chamber (15) between them for sealing off the drive shaft (2) from the pump housing (1). A device (20-25) is provided for introducing a flushing fluid at a specific pressure into the sealing chamber (15). The product-side sealing arrangement (A1) is so designed that it opens under the specific pressure in the sealing chamber (15), so that the flushing fluid can flow along the sealing arrangement (A1) into the pump area of the centrifugal pump. Owing to the flushing by the flushing fluid it is possible, among other things, to use a low friction loss face seal (11, 12) for the product-side sealing arrangement (A1) even when pumping media charged with solids.

Abstract: The invention relates to a road-sweeping vehicle. An auxillary gearbox (16) is interposed in the drive shaft (14, 15) between the engine and driving wheels (13). The auxillary gearbox can operate in mechanical mode in which the forward part of the drive shaft (14) is directly connected to the rear drive shaft (15) for normal driving. The auxillary gearbox is operated in hydrostatic mode when the vehicle is carrying out sweeping/cleaning operations. In this mode, the forward drive shaft (14) is used to drive a hydraulic pump (26) which operates a transmission motor (27) under control from the vehicle cab (11). The rear drive shaft (15) is then driven by the transmission motor (27), thereby providing fine control at low vehicle speeds, without the need for an auxillary engine.

Abstract: The weft insertion device contains a flexible insertion band (10) which can be fastened to a band wheel so that it can be wound on and unwound and which is produced from a plastic reinforced by a plurality of skein-like and/or bunch-like fibre groups (25). The fibre groups (25) are arranged in an inlay (27) which passes through the insertion band (10) over the entire length and which is surrounded by a layer of the plastic of the insertion band (10) free of the fibres of the fibre groups (25). The insertion band (10) is formed from a profiled part produced by a continuous manufacturing process, for example by pultrusion, and, in a end portion (B) remaining outside the winding region of the band wheel, is designed with a web-like elevation (10b). This is formed by a residual portion of a web-like section (10d') of the profiled part, which originally extended over the entire length of the insertion band (10) and which, in the length portion (A) of the insertion band (10) which can be wound on to the band wheel, has been removed, with the exception of a flange-like basic section (10c) of this. An easily producible low-mass insertion band (10) is obtained in this way, and in particular fibres of the fibre groups (25) are prevented from being exposed over a long period of operation.

Abstract: A method and an apparatus for wrapping a product (31), particularly a bundle of newspapers or magazines, especially an extra thick bundle or an extra thin bundle comprising a few or a single newspaper or magazine. The product is carried on a conveyor system through a plane towards a curtain of film (26) formed by an upper (6) and a lower (16) sheet of film. The curtain thus accompanies the product and is auto-sealed behind the product, after which the sheets of film are separated in the middle of the sealing region, the curtain of film being re-established and the product being provided with a wrapper. The deflection roller (9) or the like which de­fines the upper limit of the sheet of film is carried by drive means such as cylinders (30) which are arranged to displace the deflection roller in such a way that its upper portion will be supplied quickly and sub­stantially without tensile force at the start of a wrapping operation if the height of the product is slight, or at the end of the wrapping operation if the height of the product is particularly great.

Abstract: The arrangement according to this invention comprises a universal micro circuit (IC) in digital signal processing for example for storing and transmitting information in a telecommunication system. The circuit has many applications, although the field of application according to the exemplifying embodiment included concerns the storage and transmission of information between switch modules in a telephone exchange. A mircro-circuit (IC) of the given kind includes on one single silicon plate input/output units (IO) for adaption to different types of external units, memory modules (MM) which can be combined for varying memory-capacity requirements and applications, and gate-matrix part (GA) with the aid of which a large number of logic functions can be implemented. The proportion of the silicon plate area used for the memory part is considerably greater than the proportion of the area used for the gate-matrix part. The circuit enables very large scale integration to be achieved and affords in a small physical space, one single silicon plate, a high packing density, few external connections between silicon plates, which results in few internal connections on superior system levels, short propagation times and low power consumption.
