A movable carriage supports temperature controlled mold platens which can carry the skin material and which swing about a common axis to open and close. The carriage is positioned under a moving nozzle assembly which dispenses the insulation material between the skins. Means are provided to form male and female ends for the panels for interlock with other panels. In addition, means are provided so that the apparatus can be readily adjusted to form panels of varying widths.

Abstract: A system for fabricating frame structures having wood chords and web components connected by toothed plates on opposite sides of each joint, wherein an elongated rectangular bed is provided on which to assemble and connect the components, longitudinal rows of conveyor rolls bring the chords forwardly and transfer means move them laterally to areas at the ends of the bed, and the web components are delivered to the sides of the bed.

Abstract: A system for transferring motion between locations remote with respect to each other by a push-pull control cable assembly. The system employs a motion conversion unit at either or both control and controlled station, said units serving to convert rotary motion into linear motion, and vice versa. That is, a force transfer shaft is rotatably mounted in the housing of the motion conversion unit to receive, or impart, rotary motion, and the core element of the push-pull control cable assembly -- which receives, or imparts, linear motion -- extends into, or through, the unit in transversely spaced relation with respect to the shaft. That portion of the normally flexible core element which extends into, or through, the unit is made rigid to impart columnar strength. A crosshead is secured to the rigidified portion of the core element and is slidably received within a first guideway presented from the housing to minimize lateral loading to the rigidified portion of the core element.

Abstract: A rotary hydraulic motor valve operator having a rotor shaft with diametrically opposite vanes operating between diametrically opposite stops forming two pairs of fluid chambers, one chamber of each pair being connected through the top plate of the motor housing with a conduit which alternates as a supply or an exhaust conduit. Annular cross-over grooves at different levels in the top plate around the rotor shaft are connected one to the opposite chambers of each pair.

Abstract: Disclosed is a short stroke, rapid fire, continuous power rotary engine which can be affixed to the body of a vehicle or other stationary position, depending upon its intended use. The engine includes a housing within which is a rotating block which houses the pistons and at least one cylinder. A central power shaft having first and second sections mounted within the housing is connected to the rotating block. Upon ignition, the expanding gases urge the pistons radially outwardly from the axis of the central power shaft. Further provided are piston rods and means for transmitting the radially outward movement of the pistons to the rotating block, thereby imparting a rotational moment thereto. The engine also includes a fuel intake system and novel ignition and exhaust systems.

Abstract: Disclosed is a device which permits a plurality of fluids to be received in a mixing chamber simultaneously through nozzles from fluid input chambers. Actuation of a fluid cylinder opens valves so that the fluids are received under pressure in the input chambers. A second fluid cylinder then opens the mixing chamber so that the nozzles emit both fluids simultaneously which mix by impingement and thereafter are dispensed from the mixing chamber. When the valves are closed recirculation is accomplished through a plurality of ports, thereby allowing the fluids to remain at desirable temperatures and viscosity.

Abstract: Disclosed is an apparatus and method for the packaging of salable articles. The articles to be packaged are placed within spaced holders carried by an endless belt which advances the article through the apparatus while various operations are being performed thereon. A drive mechanism advances and periodically interrupts movement of the endless belt and operates a display card transfer mechanism. Movement by the transfer mechanism is in two directions, vertically, to pick up a display card from a supply and subsequently place it in juxtaposition to the article in the holder, and horizontally whereby a display card is transferred from the supply to a position over the conveyor belt and holder. Simultaneous with the placement of the display card in juxtaposition to the article, one or more labels are applied to an article and display card positioned in another holder to form a package. At least one of the labels is preformed in order to better conform to the contours of the article and display card.

Abstract: The invention relates to trays for shipping and displaying fragile articles which can be stacked with other identical and similar trays and which can be nested with identical trays. The subject trays have a plurality of pockets adapted to receive the fragile articles, lower supports extending from the bottom of the pockets and terminating in lower bearing surfaces, and upper supports extending above the pockets and terminating in upper bearing surfaces, whereby the upper bearing surfaces support the lower bearing surfaces of other identical and similar trays to effect stacking.

Abstract: The present invention is directed to a chair construction and a method for fabricating such a chair. At least a portion of the chair frame is adapted to be upholstered with a removable decorative cover, and that portion -- or a component thereof may, comprise a shell having a mounting flange and a groove extending around the perimeter of the shell in substantially parallel relation with respect to the mounting flange. A bumper embraces the mounting flange and presents an anchor rib that is received within the groove. The configuration of the exterior of the bumper as well as the anchor rib cooperates with the shell to prevent inadvertent removal. A cover overlies the shell and is secured to the bumper by hidden stitching. The cover may be infolded within the resilient cushion material interposed between the cover and the shell to present one or more decorative grooves and to preclude stressing the stitching by which the cover is secured to the bumper.

Abstract: A method for carrying out reactions of the Friedel-Crafts type, such as alkylation, acylation, polymerization, sulfonylation and dehydrohalogenation. The reactions are catalyzed by arene-metal tricarbonyl complexes and when the reaction vessel contains aromatic substrates the catalyst may be generated in situ from a metallic hexacarbonyl. The arene-metal tricarbonyl catalyst is more selective than conventionally employed Friedel-Craft catalysts in that it yields generally para isomers with little of the ortho variety and very little if any of the meta variety when the aromatic substrate is reacted with organic halide. It is also possible to form the arene-metal tricarbonyl catalyst outside of the reaction vessel and then proceed by adding it to the vessel containing the substrate and the organic halide as is the case with dehydrohalogenation reactions wherein there are no aromatic rings available, the substrate in that instance being aliphatic.

Abstract: An archery bow having a riser that is adapted to be grasped by an archer and which has a face and upper and lower, opposite end portions. The inboard ends of a pair of elongate spring members are mounted in cantilevered fashion from the face of the riser, one in association with each opposite end portion thereof. The medial portion of a limb member, in the fashion of a second degree lever, is pivotally mounted on the outboard end of each elongate spring member. A bow string extends between the outboard ends of the two limb members, and a cam follower is presented from the inboard end of each limb member to engage a corresponding cam secured to the face of the riser and which serves as a fulcrum against which the limb member acts to cock the spring member in response to the application of a drawing force to the bow string. The configuration of the cam determines the functional interrelation of the draw weight in response to the draw displacement of the bow string.

Abstract: The motor tube carrying the trolling motor at one end and a steering motor at the other end is mounted on a plate detachably supported on the bow or deck of a boat. A gear driven by an electric motor is mounted on the mounting plate and meshes with a rack on the motor tube to raise and lower it in vertical position, and raising the motor tube a predetermined amount trips a latch on the plate to allow the motor tube to rotate bodily with the gear to a horizontal stowed position on the boat. An electronic control box on the mounting plate has a receiver for remote control operation of all three motors.

Abstract: A system for controlling sequence and duration of the operational steps in processes such as vulcanization of a pneumatic tire is capable of operating under two basic modes or parameters. In one mode the operational steps are dictated by elapsed real time, while in the other mode, the operation can be dictated by elapsed cure equivalent factors. The desired length of each step or the cure, whether in time or cure equivalents, is set into an input program means. In the time mode, time generating circuitry provides an output proportional to elapsed time which output is displayed on a counter and electrically compared with the information in the input program means. When a match occurs, the time generating circuitry and displays are reset and the input program means directs the tire vulcanization press to perform the next sequential function. Also disclosed is circuitry which is capable of performing secondary functions such as extending the length of a step, as necessary.

Abstract: Disclosed is a digital control system and method for synchronizing audio-visual equipment for the presentation of film slides with corresponding sound narrations. As the film passes through conventional projecting equipment each slide receives a sequential address. Simultaneously, the sound narrations, passing through the audio equipment on a continuous media, receive identification numbers from a pulse generating means indicative of the outset of each narration, which numbers are stored in the system correlated with the proper sequential address. Means are further provided for skipping ahead or back to desired film slides rapidly, without loss of synchronization between the audio and visual portions of the program.

Abstract: A hose reel, particularly suitable for use with a mobile sewer cleaner, includes a cylindrical drum rotatable on a generally horizontal axis. A plate is affixed to each end of the drum to form the hose reel which is divided generally centrally by a third plate thus defining two hose receiving areas. Two hoses, preferably of differing diameters, are coiled on the reel, one hose in each hose receiving area. Fluid under pressure is provided internally of the reel through a pipe on the axis of rotation of the drum and is selectively channeled to at least one of two hoses coiled on the drum. In this manner, a single hose reel can be operated with different volume outputs dependent on the particular job being accomplished.
