Abstract: ABSTRACT OF THE DISCLOSURE:             Method of manufacturing shaped articles from multi-block copolymers of acrylonitrile with acrylamide and/or acrylic acid and diacryl imide, which copolymers have a structure displaying typical, circular reflexes as a 5.1 ? periodicity in x-ray  analysis and presenting two distinct but inseparable phasein the swelled state.  This method comprises molding the copolymers in the state of hydrogels by pressure in the presence of  a water containing swelling agent at temperature higher than the glass transition point of any polymeric phase present in the system, but lower then 250°C while avoiding the boiling of said swelling agent, to shape the articles with unchanged equilibrium swelling capacity and composition of copolymers. This method is in particular suitable for shaping various articles of surgery such as contact lens, tips of hydrogel catheters, pessars, plasthese of organ,...

Abstract: ABSTRACT         A  diffusion pump capable of separating impurities from its pump fluid during operation is disclosed.  Skimming drains are provided in the pump's boiler for periodically skimming the evaporative surface of the working fluid.  This eliminates nearly all contaminants of higher molecular weight than the pump fluid.          In the foreline of the pump, a series of peripheral gutters are provided for trapping, separating and draining off condensates.          The gutters facilitate the removal of impurities of lower molecular weight than that of the pump fluid.  Means are also provided for further removing trace quantities of residual volatile impurities which tend to backstream up the diffusion pump barrel.  The highly purified pump fluid allows for a more vigorously working evapora-tive surface, thereby increasing the throughput of the diffusion pump.  Together with the elimination of volatile impurities from the pump barrel, this facilitates the attainment of significantly higher ultimate chamber vacuum.  The withdrawn condensates and skimmed residues also form the basis for use of the apparatus as a device for obtaining a high degree of separation between liquids of very close vapor pressures.

Abstract: Abstract of the Disclosure A vehicle running gear with articulated, self-aligning, wheelsets having means providing elastic restraint of steering moments.  This means ensures that the axles of the wheelsets, while free to yaw conjointly to assume a radial position in curves, are restrained from unstable steering motions when operating in a relatively straight line at high speeds.  The wheelset bearings are each carried by a subtruck which is shaped to provide a steering arm, and these arms are movably coupled in a region intermediate the axles, to accommodate conjoint yawing motions of the axles with respect to each other and in the general plane of the axles,  Particular attention is given to the importance of "yaw" and "lateral" restraints, between the two wheelsets of a truck and, in each of the disclosed embodiments, resilient means of predetermined stiffness is constructed and disposed to oppose de-parture of the arms from a position in which the wheelsets are parallel, while other resilient means reacts between the steering arms, in the region of their coupling, and opposes differential yawing, or lateral motion of the axles, across the line of general vehicle motion.  Elastomeric pads or blocks are disclosed as providing the damping and, in some disclosed arrangements, the degree of restraint of the movements of one axle differs from the degree of restraint of another axle. In accordance with one disclosed feature, coupling is also provided between one steering arm and the vehicle body, to control yawing between the wheelsets and the body.  According to another portion of the disclosure, brake improvements, for a railway vehicle, reduce brake shoe wear, and eliminate contact between the brake shoes and the wheel flanges.

Abstract: Abstract of the Disclosure A clamp arrangement for securing sheet material to a base comprising a clamp having a pair of jaw plates with opposed grooves to act as jaws.  The jaws are to receive a rod with a sheet extending around it. There is a clamp for drawing the plates together to cause the jaws to grip the rod and thus secure the sheet to the rod.  The clamp comprises a bolt secured to one of the plates and extending through a hole in the other of the plates.  A locking bar is mounted for rotation on the bolt adjacent the other plate.  The bolt is arranged to prevent movement of the bar outwardly along the bolt. There is a protuberance on the adjacent plate, near the bolt.  The bar is rotatable on the bolt from a position clear of the protuberance, at which time the jaws are open, to a locking position on the protuberance to move the jaws towards each other to grip a rod and sheet between them.  The invention avoids the use of grommets, which have a tendency to tear sheets, particularly plastic sheets, and need to be inserted in the sheets.

Abstract: Abstract of the Disclosure Disclosed is a pressure ratio monitoring device for equipment having at least one floating roll and a pneumatic or hydraulic loading device engaging either the floating roll or a back-up roll.  The controlling element which is either the loading device or the floating roll, has a control pressure derived from a pressure therein whereby the pressure in the other of the loading de-vice or the floating roll (i.e. a controlled element) can be adjusted by means of the pressure ratio monitoring device to maintain a predetermined ratio to the pressure in the controlling element.  The pressure ratio monitoring device compares the control pressure with the actual pressure in the  controlled element and, when the pressure to be controlled is excessive in relation to the said predetermined pressure ratio, reduces the  pressure to the predeter-mined ratio.

The gate region includes a localized subtransistor.  The subtransistor has a locally longer minority charge carrier lifetime than the minority charge carrier lifetime in all areas of the main thyristor region.  This, the location of the initial current conduction under the conditions of excessive forward voltage is limited to the gate region.  The device permits control of the location of the turn-on point.

Reverse movement of the winch roller moves the piece of equipment rearwardly and the lines lay the equipment down on the ground in the horizontal position. Tie-down lines are provided which support the rearward portion of the piece of equipment off the ground in portions of the loading and unloading operations. These tie-down lines also assist in tying the equipment down when loaded.
