Patent CA-2295660-A1 (CA)
Inventor: ERICKSON ROBERT A
IPC: B23B31/107
Filed: 1998-07-20
Abstract: An improved coupling system for lockably coupling machine tool components is provided that includes a male coupling, a female coupling having an axis, a pair of opposing jaw members having lock surfaces for engaging ledge surfaces in the male coupling when the jaw members are moved apart, and a drive train having first and second drive spheres for simultaneously moving proximal and distal ends of the jaw members apart. The drive spheres engage ramps on the inner surfaces of the jaw members that have cylindrical profiles to provide lenticular contact between the spheres and the jaw members. Cam and follower surfaces are provided between the jaw members and one of the male or female couplings to enhance the locking force between the couplings. The invention provides a more rigid coupling between the male and female components by providing two locking spheres that operate in tandem to simultaneously spread the distal and proximal ends of the jaw members apart.

Patent CA-2310157-A1 (CA)
Title: Double valve with anti-tiedown capability
Inventor: HASELDEN DAVID W JR
IPC: F16P3/22
Filed: 2000-05-30
Abstract: A control valve system has two valve trains each of which has a series of valves which dynamically move between a deactuated position and an actuated position. An inlet of the valve system is connected to an outlet of the valve system when all of the valves are actuated and the outlet of the valve system is connected to an exhaust when all of the valves are deactuated. Each valve train includes a solenoid valve which when actuated moves the remaining valve members to their actuated position. The various valves of each valve train are interconnected with the valve of the other valve train such that actuation of all of the valves in a substantially simultaneous manner will connect the inlet of the valve system to the outlet of the valve system and deactuation of all of the valves in a substantially simultaneous manner will connect the outlet to the exhaust. The valve system monitors the dynamic movement of the valve members during its operation will move to a locked out condition when any valve is in a deactuated position and when one other valve is in an actuated position. In the locked out condition, the outlet of the valve system is corrected to the exhaust. The valve system will remain in this locker out condition until a resetting operation is performed. During a reset operation, the valve system can not actuate one of the valve trains because one of the valve trains is depressurized during the reset operation.

Abstract: The present invention refers, in general, to a process for manufacturing tufted carpets or rugs, which are used, for instance, as decoration in homes, and also to carpets or rugs produced by this process. Said process comprises the following steps: obtaining a piece of carpeting (6), prior under-finishing, from a roll of carpeting (1) manufactured by a large-scale production machine; removing the tufts (3) from a surface region of the base web (2) of the piece of carpeting (6), said region comprising an outer border region and a central region of said piece of carpeting (6); and retufting said surface region of the base web (2) with tufts (9) of a different nature by using a hand-operated tufting machine. The manufacture of the carpet or rug ends with a starching step which is characterized by placing a base onto the bottom surface (11) of the base web (2), to fix the tufts (3, 9) definitively on the base web (2). A carpet or rug is then obtained that has excellent quality and finish, comparable to any rug made by a semi-artisanal process, but with the advantage of having a much lower manufacturing cost, by virtue of the fact that advantage is taken of large scale production carpeting.

Inventor: VANDERSTRAETEN ERWIN
IPC: H01J37/34
Filed: 1998-02-09
Abstract: Material utilization and process stability for rotating cylindrical magnetron target (14) used in a sputtering structure or "race track" (12), allowing the power density on the target surface (14) to be reduced by approximately 50 % for any given point where magnetic confinement of the plasma exists. Offsetting one race track (12) relative to the other (10) along the longitudinal axis of the target (14) reduces the power density at each turn-around area (relative to the longitudinal area). Modestly increasing the target material thickness at the ends of the target allows nearly all of the material between the turn-around areas to be sputtered.

Abstract: There is provided an apparatus and method for encoding a code signal particularly into an audio signal. Previously as a result of data compression protocol codes hidden into "sync periods" have been degraded or lost as a result of, for example, low pass filtering. Sometimes, during quiet intervals codes were audible. The invention overcomes the problem of encoding a code into an audio signal by sampling the audio signal in order to determine its energy content and embedding the code into a suitable portion of the audio signal so that the code is hidden within a sufficiently energetic portion of audio signal. The advantage is that code is never audible.
