Abstract: ABSTRACT      A material for reversibly storing hydrogen is formed from a lightweight matrix which is chem-ically and structurally modified to improve its hydrogen storage properties.  The utilization of a material which can be any of a number of different disordered structures makes possible the modi-fication of local order chemical environments of the material to increase hydrogen storage capacity and/or improve absorption and desorption prop-erties.  Lightweight modifier elements struc-turally modify the local chemical environments of the matrix to provide a material having a in-creased density of storage sites to increase hy-drogen storage capacity.  Transition and rare earth modifier elements structurally modify the local chemical environments to provide a material with an increased density of catalytically active sites for dissociating hydrogen molecules to in-crease the rate at which hydrogen absorption and desorption can be accomplished.

Abstract: ABSTRACT OF THE DISCLOSURE Method and apparatus to produce a continuous filament textured yarn with unusually low crimp contraction and intermittent crimp and molecular orientation along its length.  This is accomplished by the use of an electromagnetic tension device to control the draw in the yarn being supplied to a false twist device driven at a speed to provide low false twist in the yarn being twisted.  The apparatus includes a control between the electromagnetic tension control and the yarn supply package to prevent the yarn coming off the package from rotating in a full balloon path and consequently prevent entanglement of the yarn in the yarn guides as it passes to a yarn consuming machine.

The pivotal axis of the carrier member is located adjacent a top wall of the housing and at an inner end of the carrier member which is divided so that a knife blade can pass therethrough and intersect the pivot axis.  Mounting means for the pivoted inner end of the carrier member comprises a part of the housing and a portion of a spring which also serves to urge the carrier member about the pivot axis towards the housing top wall.  The pivot axis of the carrier member is located inwards of the housing relative to the pivot axis of the latch device and a reaction portion of the latch device engages an upper surface of the carrier member at a location between those two axes.

Title: Collapsible shipping container

Granted: 1986-08-19
Abstract: ABSTRACT OF THE DISCLOSURE           This invention relates to a reusable shipping container which is higher than it is wide and can be collapsed from an erect position within itself for storage or transport.  The walls of the container have lower portions fixed to the floor to form a hollow rigid base and removable upper portions.          The upper portions have a channel running along their lower edges so that, in the erect position, they can be mounted on the lower portions and engaged to each other.  The side walls are spaced apart a distance greater than the height of the upper portions so that, in the collapsed position, they can be stored horizontally in the hollow base.  The roof has a similar downwardly open channel running around its edges which engages the upper edges of the upper portions of the walls in the erect position, and the upper edges of the lower portions of the walls in the collapsed position.  Thus, in the collapsed position, the container is still a seal unit, but is considerably reduced in height so that several of them may be stacked in the same space required by an erect container which reduces storage and/or shipping costs.

Abstract: Abstract An apparatus, method and package are provided for producing and winding bundles of filamentary material to achieve good split efficiency on removal of the plurality of bundles from the package for further processing and to produce a package of wound bundles of filaments having good edges. The apparatus has a filament forming means, an applicating means for applying chemical treating compositions to the filaments, gathering means to gather the filaments into a plurality of bundles of filaments, a rotatable winder to attenuate and wind the bundles, a slotted traversing guide, a reciprocating means, and contact means at each end of the recipro-cating stroke of the traversing guide.  The slotted traversing guide has more than one slot where the terminal portions of the slots have curved ends to retain a bundle of strands and are located directly behind the terminal portion of the preceeding slot.  The slotted traversing guide deposits the bundles of filaments on the rotating winder and as the tra-versing guide approaches the point at which it reverses to traverse in the opposite direction parallel to the axis of rotation of the winder the bundles above or below the traversing guide contact a contacting means to restrain the traversing movement of the contacted segment of the bundles to apply tension to the bundles of filaments being wound onto the winder. This additional tension assists in producing squarer edged packages having good split efficiency.

Abstract: ABSTRACT            SOLVENT DEWATERING COMPOSITION           Water-displacing compositions based on fluoro-carbon solvent FC-113 (1,1,2-trifluoro-1,2,2-trichloro-ethane) and certain surfactants are provided.  These solutions serve to displace water from a broad range of substrates, including metals such as stainless-steel, aluminum alloys and brass, as well as from glass and ceramic surfaces such as lime glasses, borosilicate glass, unglazed alumina and fired alumina.  In addition, these compositions do not form emulsions with the displaced water.  This latter property is important to efficient water removal by decantation when the drying solvent is used in commercial drying processes and apparatus.          The surfactants are chosen from a combination of:  (a) the isopropyl amine salt of a dodecylbenzene sulfonic acid; (b) 2,4,7,9-tetramethyl-5-decyn-4,7-diol combined with an aliphatic primary alcohol in the range of hexanol to dodecanol; and (c) certain aliphatic esters of polyphosphoric acid, in the free-acid form. This combination of ingredients, in appropriate weight relationships to each other, is present in the dewatering solution at a total weight of about 0.5 percent based on the fluorocarbon solvent.

Abstract: ABSTRACT OF THE DISCLOSURE      A low volume submersible pump assembly has features to stabilize the operation.  The pump assembly includes a centrifugal pump driven by a submerged electrical motor. The centrifugal pump has an impeller configuration that is  designed  for  high  specific  head,  but  potentially unstable  operation.   At  the  design  speed,  the  pump potentially could deliver an indeterminate flow rate for a given head.  Also, at the design speed, the design flow rate will yield a design head that is very close to the maximum  head  at   zero   flow.    The   pump  has  the characteristic  of  requiring  a  significant  increase  in torque to produce higher flow rates.  To stabilize the potentially unstable pump, a variable speed drive varies the  speed  of  the  motor  to maintain  constant  torque. Maintaining  a  constant  torque  allows  a  considerable variance in head with only a small variance in flow rate resulting.

Abstract: ABSTRACT OF THE DISCLOSURE     The invention provides a clamping apparatus, particularly for receiving and clampingly retaining electrode body blanks having prismatic or circular cross section for erosive machining devi-ces. A clamping block has at one of its surfaces an essentially centrally arranged clamping chamber to receive the electrode. Two adjacent walls of the clamping chamber are provided with clamping screws protruding into the clamping chamber. An approximatly central position of the workpiece in the clamping chamber is achieved by the provision of distance plates with preselectable thickness, which are inserted into the clamping chamber between two walls thereof and the surface of the workpiece, before the workpiece is clamped by tightening the clamping screws. This clamping apparatus is inexpensive and rugged, so that the elec-trode, once machined and used, respectively, may always remain clamped and therefore may be used again with a very high pre-cision as far as its position is concerned.
