Abstract: APPARATUS FOR MELTING AND DISPENSING     THERMOPLASTIC MATERIAL          Abstract of the Disclosure An apparatus for melting and dispensing thermoplastic material comprising a melter tank, a pump contained within the melter tank, a dispenser, and a manifold block mounted on the bottom of the melter tank.  Thermoplastic material melted in the tank flows from the melter tank through the pump through the manifold block to the dispenser.  The melter tank comprises a novel electrical resistance heating element cast into the bottom wall of the tank.  The heating element is asymetrically shaped within the bottom wall of the melter tank and is so configured that the length of the heater element within any portion of the bottom wall is proportional to the mass of material, including melter tank, manifold block, pump, and thermoplastic material to be heated by the given length of heater element within that portion.  Additionally, the tank side walls are generally tri-angular in cross section with the thicker part of the triangular shaped side walls located adjacent the bottom of the tank.  A portion of the heating element is located directly under each side wall so that heat is effectively conducted from the bottom wall into the side walls, and from the side walls into the thermo-plastic material contained within the tank.

Abstract: IMPROVEMENTS IN OR RELATING TO                    HEAD MOUNTING APPARATUS                            ABSTRACT    Head mounting apparatus which can accommodate dif-ferent head sizes and shapes comprises a substantially rigid member for supporting equipment, such as night vision equipment, to be used by the wearer, and a flex-ible member which can flex to adapt to the head of the wearer.  The rigid and flexible members are connected by pivotal means at pivot positions along spaced pivo-tal axes.  The flexible member has buttons for attach-ment of straps by which it is in use secured to the wearer's head.  The position of the rigid member rela-tive to the flexible member may be adjustable by manual rotation of the knobs.              BACKGROUND OF THE INVENTION  This invention concerns improvements in or relat-ing to head mounting apparatus, that is to say appara-tus by which equipment, such as for example night vi-sion equipment, can be mounted on the head of a person who is to use the equipment.    Head mounting of equipment can have the advantage over hand holding of leaving the user's hands free to perform other functions.  Notably in the night vision field there is a requirement for the user to wear the viewing equipment on his head in similar fashion to goggles.  It is obviously desirable that there should be as much comfort as possible for the wearer and this could in principle be achieved by tailoring the head

Abstract: A Mounting Apparatus for a Control Lever Abstract In the operator's station of many construction vehicles, there is a critical lack of space in which to mount the control levers used to operate the vehicle. The use of mechanical linkages and motion translating devices between the control lever and the actuator has required complicated mechanisms and excessive hardware for the mounting and positioning of the respectively connected components.  The mounting apparatus of this invention overcomes these problems by employing a detent mechanism that functions as a rotational positioner between the control lever and an actuating switch assembly as well as an axial positioner used in the mounting of the respective components.  The mounting apparatus allows the control lever and the actuating switch to be mounted together for rotation about a single axis to provide a very axially compact mechanism.

Abstract: A REDUCED IMPACT PISTON ASSEMBLY                   Abstract of the Disclosure A reduced impact piston assembly including a cylindrical body with a cavity formed therein and having a cross-bore formed therethrough which intersects the cavity.  The cross-bore receives a piston pin which has an exposed intermediate portion aligned with the cavity for attachment of a connecting rod thereto.  A wide groove is formed about the outer circumference of the cylindrical body which has its center aligned with the center of the cross-bore.  Positioned within this groove are a pair of C-shaped inserts, the legs of which abut the ends of the piston pin to prevent axial movement of the pin within the cylindrical body.  The C-shaped inserts cooperate with the pin to form a closed loop having a circumferential length which is larger than the circumferential length of the cylinder body.  In addition, a portion of each of the C-shaped inserts is in constant contact with a cylinder wall.  The C-shaped inserts are constructed of a material having a thermal expansion which is similar to the thermal expansion of the cylinder wall and less than the thermal expansion of the cylindrical body.  These features cooperate together to insure that constant contact is maintained between the inserts and the cylinder wall at both cold and hot operating conditions thereby minimizing the presence of piston slap within the cylinders of an engine.  The reduction of piston slap will minimize the noise of the engine and greatly reduce the amount of cavitation experienced on the outside of the cylinder wall.

Abstract: READER-FILLER MACHINE FOR INSERTING FILM STRIPS INTO MICROFICHE JACKETS                          ABSTRACT     A reader-filler machine adapted to insert a discrete strip of microfilm having a series of image frames into a selected channel of a microfiche jacket.  The jacket is pro-vided with parallel channels each having an entry slot adjacen-the front end.  The machine includes a film drive mechanism which cooperates with an optical viewer.  The film strip is advanced by the mechanism along the track of a track block which terminates adjacent the front end of a pivoted table which is spring-loaded.  The block includes a pair of pressure fingers projecting from either side of the track exit and a pair of flat locating guides flanking the fingers.  In operation, the user first tilts the table downwardly with respect to the track exit and places the jacket thereon to cause the guides to enter the channels on opposite sides of the channel to be loaded, thereby orienting the selected  channel with respect to the track exit.  The table is then released to cause the pres-sure fingers to engage the borders of the selected channel and to bring the entry slot of this channel into registration with the track exit.  The drive mechanism is then operated to advance the film strip or a section thereof into the selected channel, the frames on the strip being optically viewable to determine the point at which the strip is to be severed.

Abstract: A HETEROSTRUCTURE COMPRISING A HETEROEPITAXIAL         MULTICONSTITUENT MATERIAL            Abstract The method for producing a heterostructure comprising a heteroepitaxial multiconstituent material on a substrate comprises deposition on the substrate surface at a relatively low deposition temperature of a thin disordered layer of a "template-forming" material, i.e., material containing at least one constituent of the multiconstituent material to be grown, and differing in chemical composition from at least the substrate material, raising the substrate temperature to an intermediate transformation temperature, thereby causing the template-forming material to undergo a reaction that results in formation of "template" material, typically material having substantially the same composition as the multiconstituent material to be grown.  Onto the thus formed template layer is then deposited the material for the epitaxial multiconstituent layer.  The inventive method has wide applicability, and permits, inter alia, growth of essentially perfect epitaxial CoSi2 or NiSi2 on Si(100). Material grown by the method can be in form of an essentially continuous layer or a patterned layer, and can serve as the substrate for the growth thereon of further epitaxial material of different chemical composition.

Abstract: ABSTRACT OF THE DISCLOSURE       FLAME-RETARDANT CROSS-LINKED COMPOSITION AND               FLAME-RETARDANT CABLE USING SAME      The flame-retardant cross-linked composition is produced as follows:  A first compound of a metallic hydrate and a polyolefin resin free from any halogen is mixed with a silane-grafted polyolefin resin free from any halogen to form a second compound; and the second compound is silane cross-linked to form the flame-retardant cross-linked composition.  The metallic hydrate is mixed in an amount of about 50 to about 200 parts by weight per about 100 parts by weight of the polyolefin resin and the silane-grafted polyolefin resin, and the polyolefin resin is mixed in an amount of about (100 - x) parts by weight where x s the amount of the silane-grafted polyolefin resin and about 10 ? x ? about 80 parts by weight.    The flame-retardant cross-linked composition is excellent in flame retardancy, thermal resistance and forming property and further advantageous in production cost as compared to the conventional flame-retardant composition.  The flame-retardant composition according to the present invention does not produce any toxic gas such as hydrogen halide gas or halogen gas when burned.  This flame-retardant cross-linked composition is hence particularly useful for the sheath and the insulation of flame-retardant electric wires, cables and the like.

Abstract: ABSTRACT OF THE DISCLOSURE         An intake system for an internal combustion engine has a fuel injector disposed in an induction passage upstream of a pivotally mounted throttle plate having an idle position in which the throttle plate has upstream and downstream edge portions slightly spaced from the inner peripheral surface of the induction passage to define therewith narrow gaps for the passage of air and injected fuel particles.  A bypass air passage is formed in the peripheral wall of the induc-tion passage and has a downstream end open thereto to produce a jet of air directed toward the central zone of the downstream face of the throttle plate when in the idle position.  The air jet is operative to compensate for the difference in pressure between a central space immediately downstream of the throttle plate and peripheral zones adjacent to the narrow gaps whereby whirling-up of air and fuel particles just downstream of the throttle plate and resultant formation of drops of liquid fuel can be prevented.
