Abstract: A fork lift truck takes less storage space when its support wheels are raised from operative position to storage position parallel with the mast of the truck. To further minimize the space taken up by the stored truck, the rotation of the wheels upward to inoperative position uses a camming surface which also telescopingly cams the wheel and support arms inward toward the mast.

Abstract: A bristle strip for rotary brushes comprising a channel in which the closed ends of the U-shaped bristles are clamped. The channel is provided with pairs of opposed slots in its upstanding flanges or sides which receive guide lugs that project laterally outwardly to guide the strip when it is inserted in a guide track on a rotary drum and to retain it therein. Each lug is provided with an indentation for engaging the mat of bristles to hold the lug in a lateral fixed position. Due to the simple nature of the strip it can be produced at a low cost without special tooling.

Abstract: A laminated roofing material includes an aluminum foil top sheet laminated to a polyethylene film by an ionomer resin. After the sheets are bonded together they are cooled to set the resin and a asphalt coating is applied to the exposed polyethylene sheet and covered with a release paper. The roofing material is applied over an underlayment to form a roof supported by conventional sheeting material.

Abstract: A mower is propelled along the ground by a tractor and the mower includes three cutting units mounted on a frame. The three cutting units are transversely mounted on the frame to cut in overlapping parallel patterns with each cutting unit being free floating on the frame such that each unit cuts at an elevation controlled by the ground immediately under the cutting unit.

Abstract: A tamper deterrent locking device includes a cable secured to a female member, the cable forming a loop projecting from the female member with the free end thereof projecting through an aperture in the female member. The male member fits into the aperture to frictionally lock the cable between the male and female members. The loop is passed through two aligned holes in two pieces of relatively movable apparatus whereby one who moves said relatively movable pieces is required to sever the cable or disengage it from the frictional engagement.

Abstract: A laminated roofing material includes an aluminum foil top sheet laminated to a polyethylene film by an ionomer resin. After the sheets are bonded together they are cooled to set the resin and a bitumen coating is applied to the exposed polyethylene sheet and covered with a release paper. The roofing material is applied over an underlayment to form a roof supported by conventional sheeting material.

Abstract: To prevent the head of small sized bolts from being twisted off by a rotary electrically powered impact tool, a structure is provided between the outlet drive of the impact tool and the head of the bolt to minimize the torque transmitted between the impact tool and the bolt head.

Abstract: A headliner for mounting in the passenger compartment of a vehicle is formed from a plurality of layers of materials including foamed polyurethane, fiber glass, scrim and remay. The layers are bonded together under heat and pressure which cures an incorporated adhesive.

Abstract: In association with a hydrocarbon producing well, a unit is mounted to receive the discharge from the well. The unit includes a separation tank, a float shut-off valve, and a vertically oriented orifice meter.

Abstract: A panel formed as a laminate with a decorative fabric at the exposed face includes a pair of foamed resin layers as backing material. Between the foamed resin layers is a fiber glass layer for strength. Means are provided to attach the panel to a substrate.

Abstract: To prevent the head of small sized bolts from being twisted off by a rotary electrically powered impact tool, a structure is provided between the outlet drive of the impact tool and the head of the bolt to minimize the torque transmitted between the impact tool and the bolt head.

Abstract: A sewing machine sews a continuous zipper chain to two fabric side pieces. An adjacent severing device severs the sewn article into discrete units of a length selected by the operator. Operator observation of the severing device and sewn article is achieved by a mirror mounted between the sewing machine and the severing device.

Abstract: A device for deburring the inner longitudinal welding seam of longitudinally moving, seam welded conduits. The device includes an elongated frame with a trailing head on which there is mounted a cutting ring positioned to cut or deburr such seam. The cutting ring dimensions and position effects enhanced deburring. Superior spring structure and hydraulic means effect improved positioning of the device within the conduit. Also an improved dovetail connection between the head and the frame avoids breakdowns.

Abstract: The invention relates to a low temperature, dual beam vacuum deposition process for forming a hard, stress reduced, ballistically alloyed film such as diamond onto a substrate.

Abstract: A rotary phased radial thrust variable drive transmission which is lcoated between an input driving member, such as the pedal-driven sprocket of a bicycle, and an output driven member, such as the hub of a bicycle wheel which are mounted for relative rotation on a common axis, such as the axle of the rear wheel of a bicycle. The transmisison includes radial thrust linkages which are carried by the input driving member for cooperating with a surrounding cam ring assembly having a normally fixed cam profile providing a torsional thrust on the output driven member to cause rotation thereof. The cam ring assembly is selectively adjustable to vary its profile.

Abstract: A system for supplying liquid in large bottles from a point where they are filled to a dispenser having a reservoir for receiving the liquid. The bottles each have a neck which carries a cap unit for closing the spout thereof. Each cap unit has an outlet valve that is normally closed. The reservoir has means for supporting another normally closed inlet valve in a neck-receiving socket. When the neck is slipped into the socket the outlet valve of the cap unit is opened and substantially simultaneously the inlet valve for the reservoir is opened thus allowing flow of water from the bottle into the reservoir. When the bottle is removed from the reservoir as the cap unit is withdrawn from the neck-receiving socket, the outlet valve in the bottle neck cap unit is positively closed and the inlet valve of the reservoir automatically closes.

Abstract: A number of holes for individually receiving small-sized electronic parts such as chip capacitors and ceramic capacitors are formed in a strip of carrier tape to preserve these parts. The carrier tape is made of a strip of base material and a strip of double-sided adhesive tape stuck on one surface of the base material such that the area of each portion of the adhesive layer exposed through the holes is smaller than the area of each hole. The base material is made of an electrically conductive material. Alternatively, the base material may be made of a nonconductive material and the surface may be treated so as to be electrically conductive. Incisions are formed in the adhesive layer to facilitate removal of the adhesive in withdrawing the electronic parts from the tape. When the electronic parts are inserted in the holes, they are stuck on the adhesive layer, and then the tape is wound on a reel for storage.
