Patent EP-0020038-A1 (EP)
Inventor: WATTS GILBERT ERNEST
IPC: B29D29/00
Filed: 1980-05-08
Abstract: A problem encountered in increasing the tensile strength of conveyor belting is that when the belting is made thicker to increase its strength, it becomes difficult to impregnate the interior of the belting carcass. To overcome this difficulty, the invention provides a method for manufacturing solid woven beltings which comprises weaving a textile fabric carcass having a plurality of integrally woven layers of weft and subsequently impregnating and coating said carcass with a polymeric material, the textile carcass having five or seven integrally woven layers of weft and being woven in such a manner that the warp yarns define a plurality of continuous flow paths along which the impregnant can travel from the outer surfaces of the carcass to the interior core and each of the warp yarns defines such a path. The weft layers may be interlocked solely by dual function warp yarns all of which serve simultaneously to impart tension resistant strength to the fabric.

Abstract: Containers and the like pressurised containers for inflammable gases or toxic chemicals, in which the containers are punctured or otherwise destroyed, by for example a shredder (30) fed from a sealed hopper, and separated from fluid initially contained therein, in an enclosure (42) through which a stream of air passes to an exhaust outlet (40, 51) but which is otherwise sealed against the egress of gases at normal operating temperatures and pressures. The stream of air passing through the enclosure (42) is made sufficient to dilute the gases released following destruction of the containers, to a level below the flash point of the gas/air mixture.

Abstract: A heterostructure semiconductor laser (40) is characterized by having a channeled mesa (44) contiguous with the top surface (55) of the laser substrate (52). The channeled mesa (44) comprises an elongated mesa with an elongated channel (50) formed in the top surface (47, 49) of the mesa structure. The epitaxial growth of semiconductor layers over the channeled mesa produces layers having uniform thickness with smooth facet like texture and without layer surface irregularities. The channeled mesa may also be employed in the fabrication of nonplanar large optical cavity lasers.

Inventor: WILCOX DAVID E
IPC: G01M3/00
Filed: 1980-02-27
Abstract: A method and apparatus for the leak testing of filters (30) arranged in series in a housing, comprises supply pipes (40, 41) for introducing DOP particles within the housing and immediately upstream of each filter, and a hinged restriction member (54a, 54b) mounted in the housing upstream of each filter and downstream of the location at which the DOP is introduced for mixing the airstream and DOP and then dispersing the mixture over the full frontal area of the adjacent filter. A sampling device (70b, 70c) is mounted downstream of each filter for monitoring the airstream to detect DOP particles and thereby permit a determination as to whether any particles are leaking through or around the filter. The restriction member (54b) disposed between the filters serves the dual purpose of mixing the airstream and any leaking particles, during testing of the upstream filter, preparatory to monitoring of the airstream by the sampling device (70b), as well as mixing the airstream and the particles introduced by the adjacent upstream supply pipes (40, 41), preparatory to dispersing the mixture over the full frontal area of the downstream filter, during testing of the latter.

Abstract: The invention relates to apparatus for screening paper making stock, i.e. a suspension of liquid, paper making fibers and undesirable rejects, to remove a substantial portion of the rejects therefrom. 
     In one embodiment, the apparatus comprises a cylindrical screening member (20) provided with circumferentially extending screening slots (54) in the range of from greater than approximately 0.20 mm (0.008 inch) to approximately 0.76 mm (0.030 inch) in width. Bars (56) project from the inlet face of the screen and cooperate with rotating foils (46) for creating a field of high intensity, fine scale turbulence adjacent the inlet face of the screen (20). The paper making fibers and other particles of elongated thin shapes can pass through the screening slots (54), but relatively chunky reject particles, which would pass through the larger openings of conventional paper making screens, are rejected without fractionation of the paper making stock or appreciable variation in the consistencies of the feed, accepts and reject flows. The apparatus has special utility in a two-stage screening system when installed immediately ahead of the headbox of a paper machine, and also as the primary screen in a waste paper stock preparation system.

IPC: D03J1/00

Abstract: To reduce cutting errors arising through distortion of fabric during processing, marks are made on the fabric during fabric production, the marks having an accurately known predetermined relationship with one another so that distortions in the fabric can be monitored throughout the finishing thereof. The monitoring apparatus comprises a marking pen and means responsive to predetermined signals for urging the marking pen into contact with the fabric, for example a solenoid (10, 11) operating through a lever system (29, 30, 31). A pair of such marking devices can be operated simultaneously to give marks accurately opposite one another at the fabric production stage and such marks may be maintained in that relationship throughout finishing to ensure that the fabric is not distorted.

Inventor: PAZOS JOSE FRANCISCO
IPC: C08J3/24
Filed: 1981-09-07
Abstract: Polyurethane prepolymers having free isocyanate groups are treated with polyfunctional isocyanate-blocking agents to cause branching prior to or simultaneously with the addition of a curing diol. The composition containing the curing diol is molded in a conventional equipment at a conventional temperature, e.g., 100-120 °C. The resulting shaped article can be demolded in a fraction of the time required in the absence of the blocking agent. The shaped article is then post-cured within a temperature range of about 25-150 °C, during which time the curing diol, if present in sufficient amount, displaces the blocking agent and forms a cured, linear polyurethane. A typical suitable blocking agent is a substantially uncrosslinked phenol/formaldehyde resin. The curable composition can be prepared in one step from the diisocyanate, glycol, and blocking agent; and a composition containing all the components, including the curing diol, can be prepared in one or more steps. If a nonbasic blocking agent is used in the presence of the curing diol, it is recommended to use a tertiary amine catalyst to selectively catalyze the blocking, rather than the curing, reaction. The cured linear polyurethanes have good physical properties, comparble with those of the prior art polyurethane elastomers. Partly crosslinked cured polyurethanes find utility where resistance to organic liquids is important.
