Patent CA-2126324-A1 (CA)
Title: Printed circuit board apparatus with optical switching
Inventor: NGUYEN NGUYEN T
IPC: H05K7/14
Filed: 1992-12-18
Abstract: Abstract of the Disclosure A printed circuit board apparatus includes a handle which has an extension plate which extends into an optical switch so as to prevent communication between an optical emitter and optical receiver. To remove the printed circuit board apparatus from its associated rack housing, rotation of the handle is first required which moves the plate and which causes the detector to go HIGH and signal to a telecommunications system that the board is soon to be removed so that a graceful switch can be made from that board to a redundant copy thereof. The printed circuit board apparatus further includes a deflectable lever which contacts to ground the rack housing upon inserting the printed circuit board apparatus into its associated rack housing so as to provide electrostatic discharge protection. The apparatus further includes a face plate which has a generic configuration so as to potentially accommodate any user interface permutation required by any printed circuit board to be inserted into the housing, with application specific labels being applied to each face plate to cover up any holes not providing any user interface information to a craftsperson for the associated printed circuit board. An electromagnetic interference gasket shield is also provided around a circumference of each printed circuit board assembly located in the rack housing.

Title: Platinum group silicide modified aluminide coating process and product
Inventor: ROSE BERNARD R
IPC: C23C10/60
Filed: 1994-08-12
Abstract: Process for producing novel coated nickel and/or cobalt superalloy bodies having increased resistance to oxidation, corrosion and thermal fatigue at high temperatures. The process comprises applying a thin layer of a platinum-group metal, siliciding and heating to an elevated temperature to diffuse and integrate the silicided platinum-group metal into the surface of the superalloy body. Then the superalloy body is exposed to a diffusion powder composition containing sources of aluminum or aluminum/chromium metals and heated in a hydrogen or inert gas atmosphere to an elevated temperature to codeposit and diffuse aluminum or aluminum and chromium into the silicided platinum-group metal-treated surface.      Finally, the superalloy body is heated to its solvus temperature to form a ductile surface having an outer zone comprising a platinum-group metal aluminide, optionally ductilized by the solutioning therein of beta chromium. An inner stabilizing zone of silicon-rich phases is formed during said diffusion processes.

Patent CA-2132567-A1 (CA)
Title: Composite, pultruded fiberglass resinous hockey stick, method and device for manufacture thereof
Inventor: RATCHFORD DAVID
IPC: A63B59/12
Filed: 1994-09-21
Abstract: An automated machine and process for the production of pultruded hockey sticks and similar linear products. The machine comprises a rigid elongated frame and a creel bank supplying rovings from individual spools. An elongated, rigid, hollow mandrel extends substantially along the entire length of the machine supported by the frame. A veil guide directs and wraps a veil around the mandrel at the front of the machine. The machine comprises serial segments, each having a pattern card, a gathering bracket and a spiral winding station. Each segment directs rovings onto the mandrel in a longitudinal layer circumscribed by a radial layer comprising separate spaced apart, continuous rovings forming concentric helixes. The winding stations are synchronized and counter-rotate. A third pattern card converges a third longitudinal layer of rovings toward the mandrel. A resin injection die penetrated by the manifold gathers the rovings from the third card and saturates the uncompleted product with resin. Within the injection die, the mandrel has small diameter passages extending from a central bore to grooves on the surface for conveying resin from the bore to the rovings. A second veil guide directs an outer veil onto the resin impregnated rovings. A heater penetrated by said manifold heats the resultant resin impregnated product. A curing die helps to maintain the outer shape imparted by the injection die and the heater while the product cures. Modified industrial pullers are used to pull the rovings about the mandrel at a predetermined linear speed to form the product.

Patent CA-2157428-A1 (CA)
Title: Process and apparatus for dynamic soil packing
Inventor: BLANCKE UWE
IPC: E01C19/28
Filed: 1995-09-01
Abstract: Dynamic soil packing can be achieved by a procedure and device whereby the vibratory motion of the roller or one of the parts attached to it is determined, and whereby the vertical component of the vibratory force is diminished shed in the event of a disturbance (e.g., bouncing) of the basic roller vibration. The packing device is one having at least two exciter shafts synchronously rotating  in opposite directions  and arranged parallel to or in alignment with the roller axis for generating a vibrating motion, the exciter shafts being adjustable in their position  and/or  phase  relationship  so  that  the  resulting centrifugal force electively exerts horizontal shearing forces and/or vertical compressive forces in the soil.  A motion sensor determines the vibratory motion, such as amplitude, acceleration or periodicity thereof, and in connection with a control loop and adjustable pivot bearing adjusts the horizontal and vertical components of the motion to eliminate the disturbance.
