Abstract: Railroad spikes and the like are formed by apparatus having a stop contacting and limiting movement of the forwardmost end of a heated stock bar. A bending finger holds the forwardmost end in spaced relation from a stationary gripper die, while a movable gripper die engages the bar and moves it into engagement with the stationary gripper die. Cutter dies then engage the bar to form a tapered end portion at a predetermined location rearward of the forwardmost end as a head forming die engages the forwardmost end to form a spike head. The movable gripper die is urged toward the bar with a force which is proportional to the force exerted by the head forming die on the movable gripper die. The finished spike is ejected when it contacts an ejector finger.

Abstract: An improved pre-closed slide mount is described having two sides or masks which are secured together for defining an internal pocket to retain a film transparency which is inserted edgewise through an opening or entranceway in one edge of the mount and defining a window for viewing the transparency in the mount. An elevated border region formed in one mask of the mount extends transversely across the entranceway and has a sloping outer surface to provide a funnel for directing a transparency into the entranceway, and this border region has laterally sloping ends which define two spaced valleys for receiving the outer edges of a longitudinally bowed film strip serving as pusher for the inserted transparency. The outer edges of the valleys are defined by lateral transparency guides. The border region of the other mask forms an elevated roof over the elevated border region with inverted steps over the laterally sloping end portions of the border region.

Abstract: In the manufacture of double heterostructure laser diodes using liquid phase epitaxy a source crystal precedes the laser substrate crystal through the process to ensure saturation of the various melts from which epitaxial growth is obtained. The source crystal has hitherto been discarded. The source crystal, since it immediately precedes the substrate crystal, also experiences epitaxial growth of a heterostructure but with heterostructure layer thicknesses unsuited for laser diode fabrication. By suitable processing of the source crystal after it is formed with a heterostructure, light emitting diodes can be produced so contributing to a 50% reduction in materials cost.

Abstract: Methods and apparatus for drying a web of material running between a drying cylinder and a traveling covering cloth avoid the formation of air boundary layers which would impede heat exchange with respect to, and humidity removal from, the traveling web. In particular, these methods and apparatus avoid excessive wear of the covering cloth by locating a baffleplate at a distance from the covering cloth within a domain of the boundary layer, and promote a heat exchange and humidity removal through turbulence by impacting air from the boundary layer against a front surface of the baffleplate at a distance from the covering cloth, causing an exchange of air in the boundary layer and in meshes of the covering cloth. Effects of non-uniform humidity profiles are avoided by providing the front surface of the baffleplate with a varying configuration across the covering cloth.

Abstract: A thin-walled hollow partially liquid-filled cushion is permanently enclosed in a cavity formed in the sole of a shoe. Preferably, the cushion is produced by vacuum-forming a pan, having a continuous circumferential lip, from a sheet of durable, flexible, resilient, non-porous thermoplastic material, heat sealing a sheet of similar material to all but a small region of the lip, partially filling the pan with a low-viscosity liquid by means of a fine tube inserted between the unsealed lip and sheet, and sealing the sheet to the previously unsealed region of the lip. A critical feature of the invention resides in the formation of the cavity in the shoe sole to contain the cushion with the cushion walls, top and bottom in intimate contact with, and the contents of the cushion under pressure exerted by, the walls, top and bottom of the cavity.

Abstract: A biochemically tuned shoe has a heel construction that provides a force-deflection response which is optimal for a particular person and a particular use. The heel construction features a main spring that is characterized by a large vertical compliance while at the same time exhibiting an extremely high resistance to a lateral shear (horizontal compliance). The main spring is preferably a coned disk spring formed of a plastic material or a vertical stack of operatively coupled coned disk springs. The main spring can be embedded in a conventionally shaped heel formed of a resilient material such as an open or closed cell foamed rubber or plastic secured to the sole of the shoe. In other forms, the heel construction is replaceably secured to the sole by a threaded stud with or without an intermediate assembly. In a preferred form, the main spring acts in cooperation with a resilient member to extend the characteristic load deflection curve of the main spring.

The guard itself is of a relatively rigid but somewhat yieldable plastic material curved and formed both longitudinally and laterally, overlying the rear part of the toe cap and with thick padding beneath it where it overlies the metatarsal area of the shoe. The guard is designed to spread upon receiving a heavy falling object and thereby distribute the load over the entire area of the guard so as to minimize damage to the foot.

Abstract: A boot or shoe comprises a preformed portion and a portion which is molded in one piece on to the pre-formed portion and which includes the sole unit and those parts of the upper not constituted by the pre-formed portion. The pre-formed portion comprises side panels extending along each side of the shoe and a sock for underlying the foot, which sock interconnects the side panels and the side panels and sock may be made in one piece or in separate pieces which are fastened together, as by sewing, before the molded portion is molded on to the pre-formed portion. The molded portion is made from a plastics material, e.g. polyurethane, and the material does not overlap the inner face of the pre-formed portion but overlaps at least some of the marginal regions of the two side panels. The sock lies in the top surface of the sole unit. The two side panels may together extend also round the heel region of the upper and the plastics material may cover the outer face of the panels in the heel region.

Abstract: A shoe having a sole, an upper formed from a relatively soft and extensible material, a lacing strip and a bandage connecting the lacing strip with the sole. The bandage is formed from a material which is less extensible than the material of the upper. The bandage includes an elongated portion and a connecting portion which extends laterally of the elongated portion at the juncture of the bandage with the lacing strip. The laterally-extensive connecting portion transmits forces from the lacing strip to the elongated portion, and substantially prevents transmission of such forces through the extensible material of the upper. Thus, the upper is less apt to become fatigued or distorted during wear. This abstract should not be taken as a complete exposition of the present invention.
