Patent CA-1276909-C (CA)
Title: Screw-type safety cap
Inventor: LUKER EDWARD
IPC: B65D41/34
Filed: 1985-06-04
Granted: 1990-11-27
Abstract: ABSTRACT OF THE DISCLOSURE:      A threaded closure having both a tamper indicating and a non-backoff feature which locks the closure to a con-tainer to avoid unwanted loosening.  The closure takes the form of a one piece cylindrical cap with an inwardly directed bead at its open end.  The cap bead engages a complimentary bead on the neck of the container as the cap is screwed onto the container, and the cap bead snaps over the container bead to form a non-backoff seal.  The cap has a tamper indicating band attached to its lower end by frangible webs.  The band and container have complimentary stop means which coact to restrain movement of the band when the cap is unthreaded, fracturing the frangible webs giving an indication of tampering or initial opening.

Granted: 1990-11-13
Abstract: ABSTRACT OF THE DISCLOSURE By poststretching, at a temperature between about 135° and 160°C, a polyethylene fiber, which has already been oriented by drawing at a temperature within 5°C of its melting point, an ultra high modulus, very low creep, low shrink, high tenacity polyolefin fiber having good strength retention at high temperatures is obtained.  The poststretching can be in multiple stages and/or with previous annealing. The poststretching should be done at a draw rate of less than 1 second-1.  Tensile modulus values over 2,000 g/d for multifilament yarn are consistently obtained for ultrahigh molecular weight polyethylene, with tensile strength values above 30 g/d while at the same time dramatically improving creep (at 160°F (71.1°C) and 39,150 psi load) by values at least 25% lower than fiber which has not been poststretched. Shrinkage is improved to values less than 2.5% of the original length when heated from room temperature to 135°C.  Performance at higher temperature is improved by about 15° to 25°C.

Title: Composite piston
Inventor: TAYLOR ALLAN H
IPC: F16J1/01
Filed: 1987-07-09
Granted: 1991-09-17
Abstract: Abstract of the Invention A composite piston structure is disclosed which provides a simple and reliable means for joining a carbon-carbon or ceramic piston cap 11 with a metallic piston body 13.          Attachment is achieved by means of a special geometry which compensates for differences in thermal expansion without complicated mechanical fastening devices.  The shape employs a flange created by opposed frustoconical shapes 12 and 19 with coincident vertices is intersecting on the radial centerline of the piston in order to retain the piston cap.  The use of carbon-carbon for the piston cap material allows a close fit between the piston and a cylinder wall, eliminating the need for piston rings.  The elimination of extra mechanical part of previous composite pistons provides a lightweight composite piston capable of extended high temperature operation.

Title: Lift truck mast structure
Inventor: RIDDLE ERNEST J
IPC: B66F9/08
Filed: 1987-08-10
Granted: 1991-08-27
Abstract: The present invention provides an improved telescopic mast structure for a hydraulically operated lift truck. The mast structure of the present invention has reeved hydraulic hoses which do not obstruct the operator's view and a chain connecting the inner and outer telescopic sections so that the inner telescopic section moves at twice the speed of the outer tele-scopic section. This chain is located inside a U-shaped channel element that forms the mast mainframe. The U-shaped channel that forms the mast mainframe fits around the I-shaped elements that support the two telescopic sections arid the chain interconnecting the telescopic sections is in front of the I-member of the outer telescopic section and alongside of the front part of the I-member of the inner telescopic section. The chain interconnec-ting the telescopic sections is therefore in a protected location, and most importantly, it does not add any length to the vehicle.

Title: Valve for distributing particulate materials

Filed: 1987-10-22
Granted: 1991-02-12
Abstract: INVENTION:    VALVE FOR DISTRIBUTING PARTICULATE   MATERIALS     ABSTRACT OF THE DISCLOSURE A valve system for distributing particulate materials includes a housing with a number of outlets. A distributor is rotated inside the housing by motor so that its outlet registers in succession with each housing outlet. A position sensor detects registration of the distributor outlet with each housing outlet and comprises a set of spaced-apart optical transmitters, a corresponding set of optical detectors and an encoding disk mounted for rotation between the transmitters and detectors. The encoding disk has a number of circumferentially spaced transmission zones, one corresponding to each housing outlet. Each transmission zone has apertures adapted to place a unique set of the transmitters and detectors in communication thereby causing the detectors to generate a unique signal. The encoding disk is rotated such that a particular transmission zone registers between the transmitters and detectors whenever the distributor outlet registers with the corresponding housing outlet. Controls permit an operator to enter a code specifying a particular housing outlet and stop rotation of the distributor when registered with the selected outlet. The controls also comprise a programmable memory unit which permits the each housing outlet, and consequently a bin or vehicle to be filled, to be identified with any desired code.

Abstract: Abstract A continuous casting furnace (10) of modular design.  In one embodiment the furnace is made of a crucible section (16), a feed section (18) and a die section (12).  Each of these various sections are separable from the other parts, and each of these parts is in turn made up of various individual components.  Thus, the crucible section includes a refractory liner (24) made of a non-carbon containing material which may be disposed within a monolithic graphite crucible (22).  The graphite crucible is provided with a cylindrical aperture at its bottom which receives a feed tube (30), there being a soft seal (32) between the bottom of the liner (24) and the top of the feed tube (30).  The feed section and the die section are generally formed in the same manner in that there is a non-carbon containing refractory tubular member (48, 64) disposed within a graphite member (50, 62).  Between the feed section (18) and the die section (12) is a soft seal (66).  In another embodiment the crucible section and feed section are integrated, there being a monolithic graphite crucible and feed housing (100), which housing supports a crucible liner (24) and a feed tube system (102) formed of sintered alumina rammed cement.  The soft seals (34, 66) are formed of a soft felt or the like fabricated from aluminum oxide, zirconium oxide or other suitable fibers which may be impregnated with a boron nitride slurry.  The various parts are held together using conventional fastening means.
