Title: Reducing oxygen@= diffusion by plasma-coating extruded plastics pipe - comprises polymerising gaseous monomer, e.g. ethylene@ by microwaves onto pipe surface within quartz tube in vacuum space near die for pore-free coating
Inventor: BRAUN FRANZ-JOSEF
IPC: B29C48/09
Filed: 1991-08-05
Abstract: Extruded plastics pipe has surface coating to reduce diffusion esp. of atmospheric O2. The coating is a void-free deposited plasma polymerisation layer. The gaseous monomer (10) is fed into a vacuum space adjoining the extrusion die (2), where a high energy electromagnetic field (8) produces free radicals and short-chain oligomers which are deposited or condensed on the cooling pipe surface, where they are fully polymerised to an adherent coating a few micrometres thick. USE/ADVANTAGE - Avoiding equipment corrosion e.g. heating pipes and vehicle brakes, and product contamination, e.g. foodstuffs esp. beer, wine, milk, and pharmaceuticals due to gas, esp. atmospheric O2, diffusion through plastics pipes and containers. Avoiding diffusion out of pipes by refrigerants and dangerous chemicals. Avoiding attack by prods., e.g. acidic fruit juices, on pipe material, leading to product contamination. Lower cost, weight and handling and problems w.r.t. stainless steel. Improved resistance to gas diffusion w.r.t. wound film, co-extrusion, lacquer or chemical deposition. Improved resistance to mechanical damage, e.g. in underfloor heating systems; not penetrated or flaked-off by impact. Negligible change in pipe dia. permits usual jointing methods.

Title: Open-end rotor spinning unit - has yarn withdrawal tube with restrictive formations to improve the quality of specified yarns
Inventor: WASSENHOFEN HEINZ-GEORG
IPC: D01H4/40
Filed: 1992-02-22
Abstract: The yarn withdrawal tube from an open-end rotor spinning unit protrudes into the chamber of the yarn producing rotor. There is a funnel shape for the yarn to enter, and this may have a slotted formation or polygonal. Ballooning is restricted to a maximum and minimum, according to the speed of the rotor and the count of the yarn produced, as well as the type of fibre being spun. Pref. from the chamber of the rotor, a funnel leads to the central bore of a changeable unit. The part unscrews from the housing by means of a nut. The yarn withdrawal tube extends from this, and directs the yarn towards the take-up rollers and creel. The funnel shape has a slot formation (Q) in one direction, or this may be polygonal, in three directions with rounded edges, or triangular. This forms a max. and min. restriction to the movement of the yarn. With speeds over 80,000 revs/min. and a yarn count of 40 to 80, this measurement is restricted to 1mm up to 1.5mm. Under 80,000 revs/min. and a count between 40 and 15, the restriction is between 1.5 and 3.5mm. A suitable size is also selected for the entrance to the funnel which is circular, having a radius (R) between 1mm and 8mm. It is also proposed that the yarn withdrawal tube should be fitted with at least one false twist edge device. USE - The various possibilities restrict the choice of equipment to enhance the quality of the yarn being produced by the rotor.

These are under the control of a programme in an electronic circuit, so that indication is made of the relative position for each reel, and acknowledge when completed. These indicators are positioned between the rows of creel pegs when the stand is in the frame. On top of each side of the frame is a visual indicator (19) to display the requirements for each sequence, so that only reels of a particular colour or quality are loaded into the positions selected by the programme and indicated at the lights (10) and visual display. When the reel is placed in position, a record is made on the computer, with a print-out. ADVANTAGE - The electronic record ensures correct loading according to the pattern. The operation can be carried out more quickly.

Title: Spinning frame which is aligned in correct position - utilises a bracket to align the spindle prior to fitting to the spindle rail
Inventor: STAHLECKER GERD
IPC: D01H7/08
Filed: 1992-06-13
Abstract: On a spinning frame, the spindles are retained in a housing which is fixed radially to the spindle rail in a bracket. The housing is fixed into the bracket in an adjustable position and the bracket is fixed to the spindle rail without further adjustment. The spindle is contained vertically in the housing. The spindle shaft is held in top bearings (26) and it is necessary for this to be aligned with respect to the rail, to stand in a true vertical position. This is achieved by employing tools to set the housing in a correct position relative to the surrounding bracket. A gap between housing and bracket leaves room for adjustment. It is set correctly, and sealed into position by a weld between the face on the lip of the bracket, and the face machined in the housing. ADVANTAGE - The spindle is aligned into the correct position in the bracket, away from the frame, then held to the rail without adjustment being necessary.

USE - For programme-controlled assembly of cable tree line bundle used in vehicle, program-controlled household equipment, machine tool, etc.
Patent DE-4229683-A1 (DE)
Title: Paper web transport - has continuous elastic belt which distorts at hard press roller, to detach web for movement to next stage
Inventor: FUJITA NORIO
IPC: D21F7/08
Filed: 1992-09-02
Abstract: The assembly to move a paper web through the press section of a papermaking machine has elastic surfaces on continuous belt which are in contact with the paper web. The surfaces which are not in contact with the paper web remain taut in a continuous belt of less elastic material and a hard roller against the belt. When the belt is pressed against the hard roller, it is distorted so that the paper web is taken from the hard roller and carried by the belt. The surface of the belt in contact with the paper web is constant while in contact with the paper. The surface of the elastic belt travels at the same speed as the web, or faster, and with an increasing speed where it is not distorted at the point of max. pressure and on either side of it to give the effect of detaching the web from the hard central press roller. ADVANTAGE - The assembly gives effective movement of the paper web from the press section to the next stage, with high web speeds, where the pressures on the material give the required structure for a lead into the next section without trimming. Web fractures are reduced and higher web speeds can be achievedx.

Title: Continuous determination of traffic-generated pollution - employing vehicle-mounted digital signal transmitters which, on passing reference station, identify vehicle to enable pollution assessment
Inventor: ROZEK WERNER DR
IPC: G01D1/14
Filed: 1992-10-15
Abstract: A method of determining the intensity of environmental pollution generated by the vehicle (6 to 9) passing a reference station (1) is dependent on a digital signal transmitter (50) carried by each vehicle. The signals identify the vehicles type, weight, cubic capacity, fuel type etc. and the reference lines (KP1, KP2) provide a speed reference. The receivers (311, 312) transmit the signals to a CPU (30) in which they are classified w.r.t. statistically derived data wherein the exhaust emission characteristics related to the above variables enable the totalisation of CO per unit distance of travel in the locality. A video camera (K5) provides a coarse classification for vehicles not equipped with a transmitter (50). USE/ADVANTAGE - Enables more accurate measurement of pollution levels than indirect methods and is continuous unlike analytical spot check methods. Gives sub-totals per vehicle type as well as gross total.
