Abstract: Connecter Pin for Link Bracelets Abstract The invention provides an improved connector pin for use in connecting ad-jacent links of a bracelet, particularly a link watch band, together in releasable yet secure fashion so that one or more links can be readily removed with a simple cylindrical tool to adjust the length of the bracelet to the wrist size of the wearer. The connector pin is typically received in a transverse passage defined by coaxially aligned bores extending through adjacent links of the bracelet and includes an inter-mediate shaft adapted to be disposed in the transverse passage defined by the bores to provide an axis for relative rotation between adjacent links, thereby imparting flexibility to the bracelet so that it conforms to the wrist shape of the wearer, and an enlarged retaining head at opposite ends of the intermediate shaft with each retaining head being bifurcated so as to be compressible in size to enable removal of the connector pin simply by pushing one of the retaining heads through the trans-verse passage and out the other side. In a particularly preferred embodiment, the bores defining the transverse passage through adjacent links include enlarged end chambers which receive and conceal the enlarged, bifurcated retaining heads of the connector pin from view in a functionally and aesthetically advantageous manner.

Abstract: HYDROLIQUEFACTION OF COAL     Abstract of the Disclosure Coal is catalytically hydroliquefied by passing coal dispersed in a liquefaction solvent and hydrogen upwardly through a plurality of parallel expanded catalyst beds, in a single reactor, in separate streams, each having a cross-sectional flow area of no greater than 255 inches square,    each of the streams through each of the cata-lyst beds having a length and a liquid and gas superficial velocity to maintain an expanded catalyst bed and provide a Peclet Number of at least 3. If recycle is employed, the ratio of recycle to total feed (coal and liquefaction solvent) is no higher than 2: 1, based on volume. Such conditions provide for improved selectivity to liquid product to thereby reduce hydrogen consumption. The plurality of beds are formed by partitions in the reactor.

Abstract: ABSTRACT Environmental gases, e.g. air are collected in an apparatus wherein a sample bottle containing a metering orifice for admitting the gas is contained within and cooled by a bath of liquid cryogen thus creating a partial vacuum inside the bottle to draw gas into the bottle where it is condensed and stored. The apparatus includes a source of cryogenic refrigeration disposed in an evacuated space above the liquid cryogen to condense liquid cryogen boil-off. By combining evacuation and cryogenic refrigeration the sample bottle holder can be rapidly cooled to operating temperature.

Abstract: MECHANICAL LOCK               ABSTRACT OF THE DISCLOSURE      A mechanical lock normally preventing axial motion of a rod with respect to a housing sleeve that surrounds the rod includes a coil spring whose diameter is slightly less than the diameter of the rod so that the coil spring normally encircles and grips the rod tightly.  The coil spring is mounted on the rod between a bushing fixed to the housing sleeve at one end of the spring and a second bushing that is rotatable with respect to the housing at the other end of the spring.  The rotatable bushing is rotated by an actuating lever to unwind the spring so as to increase its diameter and thereby to release its grip on the rod.  Both the fixed bushing and the rotatable bushing include beveled faces which permit the last few turns at both ends of the spring to become cocked on the rod to provide a true locking engagement with the rod.  The last few turns of the spring adjacent the rotatable bushing are immediately released by a minimum of rotation of the bushing since it is not necessary for the unwinding of the spring to be transmitted through the entire length of the spring.  Because the spring is shorter than in prior locks, the entire device is shorter and accordingly more resistent to bending and lighter in weight.  The structure of the device simplifies its assembly and this, along with its reduced length appreciably reduces the cost of producing the device.

Title: Pneumatic radial tire

Granted: 1983-04-19
Abstract: PNEUMATIC RADIAL TIRE      ABSTRACT      A pneumatic radial tire has a two-ply tread reinforcing breaker with cords of filamentary material. The breaker plies are of un-equal widths and arranged symmetrically with respect to the median circumferential or equatorial plane of the tire, the overall width of the breaker being substantially the width of the overlying tread. In the region of each shoulder of the tread, the edges of one ply are folded back on themselves forming superimposed two-ply regions and three-ply regions enclosing the edges of a narrow, non-folded ply. Surrounding each two-ply region of the folded ply is a cush-ion rubber which is softer than the tread or breaker skimcoat rubbers. The breaker construction substantially eliminates breaker edge separation, resulting in a more durable radial tire which can be recapped to provide further service.

Abstract: ABSTRACT OF THE DISCLOSURE         This invention relates to a process for the production of ethylene glycol by the reaction of a mixture of carbon monoxide and hydrogen (e.g., synthesis gas) in the presence of a ruthenium carbonyl complex in which alcohols, such as methanol and ethanol, are other products of the reaction.  In particular this invention is concerned with decreasing the net production of one or more of such alcohols during the process.  This is effected by providing to the reaction an additional amount of that alcohol of which it is desired to have the net production decreased.

Abstract: ABSTRACT OF  THE DISCLOSURE     A bogie for a railroad vehicle comprises a pair of wheel sets mounted in a frame which is pivotally connected to the vehicle so that it can rotate about a substantially upright axis.   The wheel sets are connected to the frame resiliently and by links which,  upon the application of unbalanced force, axially to one of the wheel sets shifts the force-receiving end toward the other wheel set.  The links can also be disposed so that any tendency for one of the wheel sets to move downwardly relative to the frame will result in a tendency for it also to move closer to the other wheel set.          This has been found to increase high speed stability of the vehicle.
