Title: Bracing system
Inventor: TAYLOR JOHN W R
IPC: E04C3/02
Filed: 1988-04-27
Granted: 1993-12-14
Abstract: ABSTRACT OF THE DISCLOSURE           A cross-brace for connection to a pair of parallel conventional joists comprises elongate brace members assembled to form an X-shaped array, with a pair of vertical reinforcement members extending between outer ends of the brace members.  The brace members and rein-forcement members are connected to one another and, when the cross-brace is assembled with the joists, the rein-forcement members abut mutually opposed sides of the joists.  When I-beams are employed, the outer ends of the brace members and the opposite ends of the reinforcement members cooperate to form right-angled notches for snugly receiving longitudinal beam members, which are inter-connected in pairs by web members against which the rein-forcement members abut.   The web members are connected by dovetail joints to the beam members instead of simply being inserted in a conventional manner into slots in the beam members.

Title: Methods for high tc superconductor film deposition
Inventor: QIU CINDY X
IPC: H01L39/24
Filed: 1988-07-21
Granted: 1991-03-12
Abstract: METHODS FOR HIGH Tc SUPERCONDUCTOR FILM DEPOSITION           ABSTRACT OF THE DISCLOSURE      The present invention describes two simple methods to prepare high Tc multi element superconductor films. In the first method, metallic elements (or oxides) are deposited sequentially on substrates in a vacuum system.  The film composition is controlled by controlling the amounts of the source materials introduced into the boats.  In addition, one or more of the elements (or oxides) are introduced to the films by treating the films in an environment containing such elements. The other method described involves the deposition of films on substrates with arbitrary shape using a non vacuum paint on method.

Granted: 1993-05-18
Abstract: ABSTRACT OF THE DISCLOSURE           A method is disclosed of enriching raw material comprising a mixture of coal and coal spoil to produce an enriched coal product.   The method uses hydrocyclonic separation with a suspension medium containing coal, coal spoil and a liquid and includes the steps of supplying raw material to the intake of a first stage of hydrocyclonic separation, and extracting at a first output of the first stage of hydrocyclonic separation an enriched coal product and extracting at a second output of the first stage of hydrocyclonic separation a mixture of coal and coal spoil.          The mixture of coal and coal spoil from the second output of the first stage of hydrocyclonic separation is then passed to the intake of a second stage of hydrocyclonic separation, and a middling type material is extracted at a first output of the second stage of hydrocyclonic separation and a refuse type material is extracted at a second output of the second stage of hydrocyclonic separation.   The middling type material is divided from the second stage of hydrocyclonic separation into a first part and a second part, the first part being directed to an intake of the first stage of hydrocyclonic separation and the second part being directed to an intake of the second stage of hydrocyclonic separation.

Title: Optical transform system
Inventor: WINDEBANK ROBERT W
IPC: B60R1/08
Filed: 1988-10-20
Granted: 1993-07-06
Abstract: ABSTRACT   Method and apparatus for generating compound shapes in optical surfaces needed to accommodate variable magnification, off-axis projection, reflection from diverse surfaces, reflector relay, intensity pattern requirements and othercomplex optical transform functions The present invention finds particular application in automotive rearview mirrors (either inside or outside mounted) where it is desired to view wide angles and in automotive headlights where it isdesired to illuminate specified targets with a desired or required intensity pattern. The present invention permits the realization of mirrors of such capability by providing a variable magnification mirror. The surface generation capabilities permit controlled magnification changes that nevertheless are still image forming and typically avoid the human eye focussing difficulties normally associated with variable magnification mirrors. The present invention includes a computer drivenreflector, design system which permits the designer to see the field of view, ray tracings, reflected beam intensity pattern and other data pertinent to a variable magnification mirror from entered mirror specifications. The effect of changes in specifications can be rapidly determined and a final design achieved through one or more such reiterations. The system further determines machine tool motional control for grinding a surface corresponding to the entered mirror specifications. A machining center having a high speed bit, a EDM tip and capable of producing the surface with optical quality precision is a further part of the invention. The ?ability of the invention in producing irregular optical shapes for these applications is utilized for the production of mirrors that accomplish complex focussing functions for use in off axis projection mirrors, relay mirrors, and headlamp reflector mirrors. According to the invention, optical systems capable of accomplishing such complex focussing can be realized with a single reflector.

Patent CA-1303314-C (CA)
Inventor: GELLERT JOBST U
IPC: B29C45/28
Filed: 1988-12-16
Granted: 1992-06-16
Abstract: ABSTRACT OF THE DISCLOSURE         A valve gated injection molding system having a double acting pneumatic rack and pinion valve pin actuating mechanism.  The melt passage branches in a manifold from a central inlet and flows along the valve pin in a central bore in the nozzle to the gate.  A pneumatically driven piston pivots a toothed pinion member mounted in a slot in the manifold.  The pinion member engages a toothed rack member which reciprocates along a straight line in the slot in the manifold and engages an enlarged head of the valve pin in a slot in the rack member.  Lateral forces from the pinion member are absorbed by sliding contact of surfaces of the rack member against matching surfaces of the slot and/or a valve pin bushing, and are not transmitted to the valve pin.  This avoids uneven wear and buildup of melt deposits around the valve pin which can otherwise result in leakage and malfunction.
