Title: Rising sifter for loose bulk material - has accurately controlled flow speed through by=pass and measuring probes
Inventor: GOERLITZ FRANK-OTTO DIPL ING
IPC: B07B11/06
Filed: 1990-11-06
Abstract: The sifter has a sifting shaft and a supply shaft opening into the wall thereof. The amount of air in the sifting channel is determined and then the amount of loose material and/or quantity of fluid is regulated, or the amount of material supplied is determined and then the amount of fluid is regulated. The filling level in the supply shaft is controlled so that the amount of material supplied is dependent on the adjustment of a supply member mounted in the transition area between the filling and sifting shafts. A by-pass pipe (6) with variable inflow cross-section opens into a connecting pipe (7) between the sifting shaft (1) and blower (5). ADVANTAGE - A low flow speed can remain constant in the sifting shaft.

Patent DE-4040027-A1 (DE)
Inventor: ULRICH ALFRED DR ING
IPC: E01C19/48
Filed: 1990-12-14
Abstract: A method for adjusting the thickness of a course consisting of road-building material to be laid down by a finisher on a foundation by raising a laying-down board of the finisher to a height adapted to the desired thickness, and a finisher suitable therefor are described, the laying-down board of which finisher is connected to the finisher via an articulation point for floating support on the course, the articulation point being height-adjustable via a first lifting cylinder, and the laying-down board being connected to a second lifting cylinder which is unlocked during laying down. In order to simplify the adjustment of the thickness of the course to be laid down, it is proposed to place the laying-down board flat on the foundation for initial adjustment of the course thickness, to determine this position by measurement transducers and subsequently to raise the laying-down board by the first and second controllably height-adjustable lifting cylinders to a height corresponding to the desired laying-down thickness plus rolling quantity. <IMAGE>

Title: Data rate matching method using packing data - storing input words in registers of buffer memory, controlling multiplexer w.r.t. number of bits in output word and varying bits in synchronising word
Inventor: PITZ STEFAN
IPC: G06F5/06

Abstract: The data rate matching system uses packing information which is identified via packing words. Several input words (DB1,DB2) are temporarily held in registers (R1,R2) of a buffer memory (ZS). A multiplexer (ME) is controlled by the number of data bits of the output works (OK), for interlocking the data bits of the stored input words (DB1,DB2). The matching between the clock frequency of the input words (DB1,DB2) and the pulse frame of the output words (OK) is obtained by altering the number of bits in a synchronising word. ADVANTAGE - Reduced circuit complexity.

Title: Multifilament extrusion installation to produce fibrous web from plastic material - has layers of woven wire sieve to provide plastic gauze used for filters, masks and nappies
IPC: D01D4/02
Filed: 1991-07-12
Abstract: The installation consists of a container with heating arrangement, and a build up of pressure on the fluid plastic. The heated molten plastic is drawn out finely through an extrusion arrangement into an airstream, then laid flat as a web on a conveyor band. The extruded threads have a very small dia. The airflow is created by a pump with connections below the conveyor band. The extrusion chamber is approximately 1.8 m wide and has a central container for the plastic. The supports hold layers of woven wire sieve. The plastic is kept at 250 deg.C to enable it to flow under pressure. The layers of sieve are arranged to filter impurities, and to provide very fine passages which do not easily become blocked. The finest gauge is placed on the top. This provides a multijet extrusion unit, the full width of the container. ADVANTAGE - The design is an economical soln. to the problems associated with prodn. of filter gauze for air filters, masks and nappies.
