A continuous flow centrifuge system having a disposable fluid container of constant cross-section mounted in a circular channel. The channel, defining a separation region, has a constant height and side walls of divering spirals to increase the cross-sectional area from inlet to outlet. The container expands dynamically to conform to the claimed geometry and the collection chamber is attached to t...

A system for preparing and splicing two yarn ends has preparation nozzles in a turbulence chamber adjacent the end faces of a casing. The preparation nozzles improve the quality of the splicing by thinning the yarn ends. Compressed air or a partial vacuum can operate the preparation nozzles. With preparation of the yarn ends in the turbulence chamber for the splicing, the expenditure for a prepara...

A running web of tipping paper in a filter tipping machine is attracted to the peripheral surface of a rotary suction conveyor constituting a counterknife for a set of equidistant knives which are radially movably mounted in axially parallel grooves of a rotary knife carrier. Each knife is adjustable radially of the carrier by a discrete first adjusting device, and all of the knives are adjustable...

Apparatus for the pocketing of positive or negative plates for batteries and for the stacking of pocketed and unpocketed plates, including a magazine for the plates which are to be pocketed in a separator strip unwound from at least one spool (1), a welding device (12) for welding together the side edges of the pieces (9) of separator strip folded about the plates, magazine (13, 14) for further...

The invention relates to the glass industry and more particularly to glass carrying a multilayer reflective coating, a metallic layer being in contact at least on one side with a metal oxide or semiconductor layer. The invention proposes to remove, especially in the region of the edges of the glass sheets, at least the upper coating layers, without attacking the glass, i.e. the possible layers ...

Reaction injection molded polyurethane elastomers reinforced with inert fillers are made by reacting two streams with one another, one stream containing polyisocyanate and the other stream containing at least one active hydrogen-containing material, wherein all the inert filler is placed in the isocyanate-containing stream before mixing and reaction with the active hydrogen-containing stream. The ...

Raw materials are reclaimed from magnetic tape scrap by cutting the scrap into small pieces; treating the cut scrap with aqueous alkali solution; stirring the alkali-treated scrap at high speed thereby completely separating them into tape substrate and magnetic powder; washing the scrap with water and draining it; stirring only the tape substrate fragments at high speed under vacuum and at a tempe...

A bore-hole logging electrode structure for a drill string, includes a drill string segment (10) having a recess (16) along an axial length thereof, a sleeve (48) of electrically nonconductive elastomeric material in said recess (16) and a plurality of bands (49) of electrically conductive elastomeric material embedded in said insulating sleeve (48) to constitute the electrodes.

An expanded plastics material has distributed therethrough a fire- resistant powder i.e. an intumescent material or the ingredients thereof. Expanded plastics material is made by subjecting expandable beads or granules of the plastics material to pre-expansion; and subsequently moulding the pre-expanded beads or granules; wherein prior to the moulding, the beads or granules are mixed with the fire...

An arrangement for testing a photomask (2) for defects, includes two identical lens systems which produce respective images of portions of the photomask on rows of photosensors (15, 16). Signals from the photosensors are compared to indicate defects in the photomask. Two further rows of photodetectors (13, 14) are provided for determining positional errors of the image formed on the photosensor ro...

The device, which is connected to an element to be displaced, comprises a tubular body surrounded by sleeves which are inflated to a diameter slightly smaller than the diameter of the conduit. A motor-pump assembly located in the tubular body provides for the circulation of the fluid through the body so as to cause propulsion of the device within the conduit. Sensors may control automatic operatio...

An electromechanically reciprocable load has a driving spring tending to displace it from a retracted position into a working position upon the release of a locking brake. The spring force is opposed by the countervailing force of an electric motor which, during the working stroke, is progressively reduced in keeping with the diminishing force of the relaxing spring. When the load includes a calip...

A process for producing a molded article of a high polymer of acetylene, which comprises press-forming a gel-like material or swollen material composed of 5 to 95% by weight of a high polymer of acetylene having a cis content of at least 50% and 95 to 5% by weight of an organic solvent at a temperature of not more than 50 DEG C. and a pressure of 10 to 1,000 kg/cm2 with or without prior treatment...

A method for recovering data from a data signal originating from a downhole apparatus and transmitted to the earth's surface through drilling mud comprises measuring pressure pulsations in a mud flow line at the earth's surface in two spaced apart locations (30, 32). One of the measured pressure pulsation signals is time shifted an amount equal to the travel time of the group propagation acoustic ...

In a process for obtaining caprolactam by cleaving caprolactam oligomers by passing them through an alumina catalyst bed at an elevated temperature, the improvement that the oligomers are introduced, as liquid or solid, into a fluidized bed of alumina and are cleaved at from 290 DEG to 400 DEG C. in the presence of steam.

Low-solvent, stable, aqueous dispersion of (a) 35 to 65% by weight of epoxide resin having a mean epoxide equivalent weight of about 250 to about 5,000 and (b) a non-ionic dispersant in the form of a polyalkylene glycol derivative, which contains as component (b) 2 to 20% by weight of dispersant comprising condensation products of polyalkylene glycols having molecular weights of 200 to 20,000 and ...
