Title: Non-ionising EM or ultrasonic radiation-pervious object analysis method - using linear and multiple emitter detector system with radiation or sound irradiated at respective wavelength range on translucent object
Inventor: SCHWARZER NORBERT
IPC: G01N29/11
Filed: 1991-05-10
Abstract: The necessary radiation power for each emitter (S1-S3) is increased or lowered, successively for each emitter adjusting the irradiation intensity continuously or in steps from zero or to any fixed value, e.g. to a max. or a min., for the responding of the last detector (D3) arranged at an angle to the emitter. The back scatter intensities are measured at an angle to the emitters as well as in parallel to the emitters, and from this taking in to consideration the multiple stray processes, the absorption coefficients of the differentiable object regions and the susceptibility of the stray regions are determined, and these are used for the reconstruction of the material and structural distribution lying in the measurement plane of the linear detector system. Each emitter (S1-S3) is assigned an axially directed detector (sD1-sD3) and several further detectors (D1-D3) arranged at an angle and parallel to the emitters. A number of these units placed together are combined to form a linear system, which can be combined optionally to form an areal measuring system. ADVANTAGE - For non-destructive material testing or examination of biological tissue for pathological morphological inhomogeneities. For selective, spatial, differential structural analysis, using non-ionised radiation light, IR, X-ray or ultrasound, to obtain three dimensional tomogram, with low material cost.

Filed: 1991-07-15
Abstract: The preheater to raise the temp. or separate the charge material for an electrical  blast furnace, has a collector with specific feed channels for O2 carriers and fuel connected to a distributor head and jets within the blast furnace. The distributor openings (6,7,8), connected to particular feed channels, have extended slits in the outflow direction to give a fan-shaped flame. The distribution head (9), pref. has at least one distributor channel (5) for the fuel, and a channel (6,7) for an O2-carrier, arranged at two different working planes which divide the distributor head (9) into separated zones. Two channels (6,7) can form an O2 body with a gap between them for the fuel channel (5),  in 3 planes, to give sepd., zones in the distributor head (9).  Cooling channels (14) are connected to the coolant supply and exhaust systems. The appts. is mounted to a side wall of the blast furnace by a conter frame to carry the collector, which pivots at the side of a frame which matches the opening in the wall for the burner assembly to pass through. The pivot action allows the distributor head (9) to swing on the vertical axis -. clear of the furnace. ADVANTAGE - The appts. gives a good heating action, and does not require the burner to be moved.

Title: Membrane filter system - feeds part of recovered watery phase back to cleaning system for workpieces
Inventor: DAIBER THOMAS
IPC: C23G1/36
Filed: 1991-07-18
Abstract: In the membrane filtering process for used cleaning fluids soiled by emulsified oils and/or grease, such as after cleaning mechanically processed workpieces, the fluid from the membrane filtering circuit is taken and thermally demulsified. At least part of the recovered watery phase is returned to the cleaning process.

The boiling and dwell phases occur simultaneously, but are sepd. from each other. Part of the fluid from the membrane filter circuit is evaporated, and the condensation is returned to the rinsing stage of the workpiece cleaning process, and part of the vapour is used for the thermal demulsifying operation. ADVANTAGE - The system gives an increased recovery of fluid with active washing substances for further use.

Title: Spinning station sliver insertion
Inventor: BUECHNER THORSTEN
IPC: D01H9/00
Filed: 1991-08-10
Abstract: To insert a sliver into a spinner, esp. an open-end spinning appts., with a feed unit and insertion funnel and injector, the feed is opened and the sliver is gripped pneumatically by the injector to be moved through the insertion funnel by air passing through passage openings aligned towards the entry of the funnel. The sliver moves through the insertion funnel into the feed mechanism, which is then closed.     For sliver insertion, the injector is pref. brought to the spinner and, after insertion, is retracted. Before insertion, the leading end of the sliver is twisted into a point by an eddy airstream from a compressed air jet. The onwards movement of the sliver is mechanically assisted during insertion. The sliver moves at a given speed at the feed funnel, and the sliver speed through the feed system is less than the speed of the sliver through the air streams alone, to give a drawing action to the sliver.

Patent DE-4135839-A1 (DE)
Inventor: BRUCKNER HELMUT
IPC: H05K3/38
Filed: 1991-10-31
Abstract: The description relates to a process for manufacturing an at least two-layer printed circuit with a base plate, a first conductor plane with contact areas (pads) and a second conductor plane with connecting areas (solder eyes) in which a conductive film with an adhesive layer is laminated on the base plate with the first conductor plane and the pads, whereby the adhesive layer and the conductive film has holes corresponding to the pads of the first conductor plane. The perforated conductive film with the adhesive layer is pressed on the base plate with the first conductor plane at a pressure of 50 to 150 bar and a temperature of at least 80  DEG C and thus laminated, whereby the contact areas of the first conductor plane are caused at least partially to bulge through the holes in the adhesive layer towards the surface of the connecting areas of the second conductor plane so that the surfaces of the connecting areas are at a distance from the surface of the connecting areas of the second conductor plane which is shorter than the thickness of the connecting areas. The second conductor plane with the connecting areas (solder eyes) is then produced from the conductive film, whereby the solder eyes of the second conductor plane border the holes in the adhesive layer, whereupon the pads of the first conductor plane can be electrically connected to the corresponding solder eyes in the second conductor plane by soldering or by the application of a conductive paste.

Patent DE-4302915-A1 (DE)
IPC: A47L13/59
Filed: 1993-02-03
Abstract: A press (1) is used for wringing textiles used for cleaning, in particular mops, dusters, scouring pads, etc., which may be fitted to a support element fixed to a handle. The press consists of a housing with two sidewalls (4) and a press basket (2) located therebetween which receives the textiles to be wrung. A movement mechanism propels pressure pieces (5) into the press basket (2), which then contact the textiles and squeeze them out. The movement mechanism for transferring the power of the drive movement from a drive lever (13) to the pressure pieces (5) operates via cam plates (14) with bridging members (6) adjacent to the two pressure pieces said members being operated by the control cams of said curved plates. This eccentric transfer of force ensures that considerable force is conveyed, while causing minimal wear. In addition, it simplifies the design of the movement mechanism.
