Abstract: A caster includes a support plate and a yoke adapted to support the support plate, the yoke being pivotably joined to the support plate for rotation about a generally vertical axis. An axle is support by the legs of the yoke and at least one wheel is rotatably supported on the axle. A first ball bearing assembly is provided including a bearing race surrounding the axis of rotation of the yoke and a plurality of balls housed in the race. A second ball bearing assembly is spaced from the first ball bearing assembly and is positioned above the axle, the second ball bearing assembly being adapted to transfer a substantial majority of the weight applied on the support plate to the caster wheel.
Abstract: A plastic ring has a circumferential groove formed in its outer peripheral surface. The ring is fitted in a bowl-type centrifuge rotor such that the ring's outer surface contacts the inner wall of the rotor. The channel is defined by the groove and rotor wall. The rotor is filled with a compensating liquid to reduce centrifugal stress on the plastic and to reduce leakage from the channel.

Abstract: This invention is directed to phosphinylmethylaminocarbonyl imino acid compounds of the formula ##STR1## wherein X represents various unsubstituted or substituted imino acids or esters.
Abstract: A shoe comprises a sock formed of fabric material and a reinforcing structure of plastic material which is directly injected onto the sock. The reinforcing structure covers predetermined parts of the sock to form a toe region, a reinforcement for the heel region, an edging which surrounds the shoe opening, and one or more transverse bands, all parts of the reinforcing structure being mutually integral with each other. The sock comprises at least one lateral part forming an upper and a base part formed of a fabric which is less than the fabric forming the lateral part. The reinforcing plastic structure includes a shaped grid-like portion formed by mutually intersecting ribs which penetrate through the less dense fabric of the sock base part into the inside of the sock from its outside. The grid-like portion thereby constitutes gripping projections which bonds the plastic reinforcing structure securely to the sock and further functions as a support for an insole.

Abstract: Antiinflammatory activity is exhibited by steroids having the formula ##STR1## and the 1,2-dehydro, 6,7-dehydro and 15,16-dehydro derivatives thereof, whereinone of R.sub.1 and R.sub.2 is alkyl, cycloalkyl, aryl, arylalkyl, or --CH.sub.2 X wherein X is alkylthio, alkoxy, aroyloxy, alkanoyloxy or alkoxycarbonyl, and the other is alkylthioalkyl, alkoxyalkyl, alkanoyloxyalkyl, aroyloxyalkyl, alkoxycarbonylalkyl, carboxyalkyl or arylalkyl;R.sub.3 is hydrogen, hydroxy, alkoxy, aryloxy, oxo, methylene, alkylthio, arylthio, alkanoyl, alkanoyloxy, or halogen;R.sub.4 is carbonyl or .beta.-hydroxymethylene;R.sub.5 is hydrogen or halogen; andR.sub.6 is hydrogen, methyl, hydroxy, alkanoyl or halogen.
Abstract: An apparatus for mounting flexible printing plates on printing cylinders. A frame is fixed with respect to a printing cylinder and a plate is fixed on the frame by keys. When an end of the plate has been adhered to the cylinder, the keys are detached and the rest of the plate is applied to the cylinder.
Abstract: A device for cleaning and recovering paper pulp includes a tank divided into inner and outer chambers by a fixed cylindrical sieve. The inner chamber also contains a rotating drum with blades that draw acceptable pulp from the outer chamber through the sieve to the inner chamber for discharge and moves rejected material through a helical path in the outer chamber toward another discharge point. The end of the helical path is blocked to form a dead space where the rejected material is concentrated and then periodically discharged.
Abstract: A bottle closure for a beverage bottle is disclosed. A threaded bottle neck receives a hollow extractor having threads complementary to those of the bottle neck. The extractor is engaged with the bottle neck. The extractor has a crown portion including an aperture that is coaxial with a bottle opening; it also has an annular protuberance that is coaxial with the bottle opening. A bottle cork may be inserted through the extractor and into the bottle neck to seal the bottle. An upper portion of the cork is grasped by the annular protuberance such that the extractor grips the cork more firmly then the bottle does. Disengaging the extractor from the bottle neck withdraws the cork from within the bottle; engaging the extractor with the bottle neck advances the cork into the bottle to thereby seal it.
Abstract: A modular jack suitable for mounting in a punched hole in a panel board. The jack has a rear end that fits into the hole and a front face that does not pass through the hole. The jack is held in place with a lock nut affixed to the rear end of the jack at a position flush with the panel. Flexible locking ears on the locking nut frictionally engage the jack.
Abstract: Nonhygroscopic, anionic pentacoordinate silicate, for example, ##STR1## soluble in commonly used organic solvents, and useful as a source of fluoride, cyanide or azide anion and as a catalyst or cocatalyst in polymerization systems, for example, the polymerization of methyl methacrylate.
Abstract: A monohydrate of a steroid having the structure ##STR1## and the 1,2-dehydro derivatives thereof, is provided which monohydrate is in the form of a particulate material having a stable average particle size of less than about 20 microns. Cream and lotion formulations containing the steroid monohydrate and a method for forming the monohydrate are also provided.

Abstract: A meter clamping ring for securing an electric meter housing of the type haing a peripheral mounting flange to a meter socket, comprising a clamping ring having ends with portions adapted to overlap to align lock receiving openings. One end is provided with a housing for enclosing the lock. In one embodiment of the invention, the end portions have cooperating means allowing them to be snapped together into the bolt-receiving position to facilitate assembly of the bolt. Resilient means is provided on the inside of the ring which is dimensioned to be flexed against the meter mounting flange when the ring is assembled to prevent any looseness between the ring and the mounting flange resulting from manufacturing tolerances.
Abstract: A trash rake is disclosed for cleaning the bars of a water intake bar screen. A carriage carrying a pan is mounted for movement parallel to the bar screen. Along the transverse edge of the pan proximate to the screen is a rake member whose teeth are received between adjacent bars during one direction of displacement of the carriage. A watertight recovery gutter for collecting foreign bodies, including living creatures, is arranged in continuity with the rake member and maintains the foreign bodies in water during the ascent of the pan. Preferably, the recovery gutter has a trapezoidal cross section and a transverse wall portion running directly into the rake member which makes an angle of at least 30.degree. with a horizontal plane when the rake member engages the bar screen.
Abstract: Melt-processible polyester which is optically anisotropic in the melt phase and which consists essentially of the following molar amounts of the recurring units, with the sum of the molar amounts being 100%:(a) about 20 to about 85%, of ##STR1## (b) about 15 to about 80% of approximately equimolar amounts of ##STR2## wherein each of X.sup.1, X.sup.2, X.sup.3, and X.sup.4 is independently selected from H, Cl, and CH.sub.3 ;Ar is selected from 1,4-phenylene, 1,3-phenylene, 4,4'-oxybiphenylene, 4,4'-biphenylene, and 2,6-naphthylene;Ar.sup.1 is selected from ##STR3## and n is 0 or 1.
