Inventor: KUO GARY
IPC: E06C7/06
Filed: 1995-09-08
Abstract: Disclosed is an extension ladder mainly including a pair of telescopic legs consisting of a plurality pairs of straight round tube members, a plurality of rungs in the same numbers as that of the tube member pairs and each having two lateral ends for the two legs to pass therethrough, a plurality sets of locking mechanisms and lock ensuring mechanisms, and a general switch assembly disposed beneath the lowest rung. The tube member each has a sleeve member and a plug assembly disposed around a top end and in a bottom end, respectively. Each plug assembly includes a set of cover members and a set of inserts having an upper and a lower movable hook members connected thereto. The upper hook member in a lower tube member separately links with the lower hook member in a higher tube member, limiting the tube members of the telescopic legs to be sequentially extended stair by stair. The upper hook member each has an air cock provided at a bottom end thereof to close or open an air port formed on a base of the inserts. The air cocks and the air ports, together with two one-way valves separately disposed at a lower portion of the lowest tube member pairs, enable the ladder to be quickly extended from a collapsed state and be collapsed from an extended state at moderate speed. The locking mechanisms and lock ensuring mechanisms are disposed beneath each rung to effectively prevent the ladder from unexpectedly collapsed due to any accidental touch of the locking mechanisms. The general switch assembly serves to actuate and control the sequential and moderate collapse of the rungs.

Patent CA-2161907-A1 (CA)
Inventor: ZUERCHER JAN A
IPC: B23P15/00
Filed: 1995-11-01
Abstract: A lift valve communicating with a compression chamber of a variable capacity screw compressor is set forth including a valve housing, a piston reciprocally received within the valve housing, a shaft having a first end connected to the piston and a second end extending from the housing. The valve further includes a valve element connected to the second end of the shaft having a valve surface exposed to the compression chamber and a reciprocation mechanism for reciprocating the piston within the housing. The reciprocation mechanism includes a first pressure passage communicating with the housing adjacent a side of the piston, and a second pressure passage commllnicating with the housing adjacent and opposed side of the piston, wherein the valve surface is positively displaced toward and away from the compression chamber of the variable capacity screw compressor in response to the application of fluid pressure to at least one of the first and second pressure passages to vary the capacity of the screw compressor. Further, the lift valve is manufactured integral with the manufacturing of the compression chamber of the variable capacity screw compressor. This manufacturing process includes securing at least one lift valve to a housing of the variable capacity screw compressor in an operating position. Once secured to the housing, the shaft and consequently the valve element is fully extended from the valve housing and maintained in such position thus simultaneously machining an inner surface of the compression chamber and the valve surface such that the valve surface forms a continuation of the inner wall of the compression chamber when the variable capacity screw compressor is operating at full capacity.

Inventor: KHENNACHE OMAR
IPC: B29C69/00
Filed: 1996-08-05
Abstract: The disclosure describes a method of making a molded article having a film layer on its exterior surface that provides a surface finish to the article; the method consists in first placing a thermoplastic film in a two-partmold having a negative recessed border undercut in one of its part and in vacuum forming, under heat conditions, the film to make a preform having inward folded edge having a shape corresponding to that of the recessed border undercut. After removing the preform from the mold, part of the preform edge is trimmed to leave an inward peripheral edge along the preform which is then placed in a second mold wherein molten plastic is blown or injected; the plastic of the peripheral edge melts with the plastic to provide an intimate bonding at the peripheral edge of the article.

Abstract: A launch vehicle which employs a rotor similar to a helicopter.  The vehicle has a four bladed rotor which is mounted on the vehicle body.  The body of the vehicle includes propellant tanks and a payload compartment contained within an integral aeroshell.  Rocket engines used to propel the vehicle into earth orbit are mounted at the ends of the rotor blades.  The engines are connected by propellant feed lines to a propellant transfer hub surrounding the axis of rotation of the rotor. Propellants are fed from an oxidizer tank and a fuel tank through a propellant transfer coupling to oxidizer and fuel lines which extend to the engines at the rotor blades ends.  The rotor blades incorporate air foils.  To operate the vehicle the vehicle is positioned on a concrete or asphalt pad and fueled with liquid oxygenand kerosene.  The engine are positioned tangent to the blade paths and ignited.The thrust of the engines which is tangent to the rotor causes the rotor to turnwhich accelerates the rotor thus increasing the pressure developed by the propellants as they flow towards the engines.  When the rotor has reached operational speed the airfoil creates sufficient lift that the vehicle begins to ascend vertically.  As the vehicle exits the atmosphere the rocket engines are aligned with the flight path of the vehicle.  After reentry from earth orbit the vehicle utilizes the spun up rotor to fly the vehicle to a soft landing.
