Patent CA-1284011-C (CA)
Title: Grain silo sealing
Inventor: NETHERY TIMOTHY J
IPC: E04H7/30
Filed: 1987-03-03
Granted: 1991-05-14
Abstract: ABSTRACT            An expansion joint for a grain silo is sealed by a mesh-reinforced diaphragm having its peripheral edge-portions bonded to surfaces of the silo adjoining the joint to form a continuous seal around it. The intermediate portion of the diaphragm has a flexible bulging portion protecting the joint and spaced from it. The diaphragm is made by covering the joint with a separating strip and applying a thick continuous layer of a viscous sealing agent over the exposed faces of the strip and the adjoining silo surfaces. The mesh is incorporated into the layer and has stiffly-resilient strands extending in the direction of flexing of the diaphragm. The layer cures to form the diaphragm which separates spontaneously from the separation strip the first time the silo expands, to form a bulging portion in the diaphragm around the joint.

Title: Method and apparatus for tilted alignment of liquid crystals with improved photostability
Inventor: MILLER LEROY J
IPC: G02F/
Filed: 1987-09-14
Granted: 1994-04-12
Abstract: METHOD AND APPARATUS FOR TILTED ALIGNMENT OF LIQUID CRYSTALS WITH IMPROVED PHOTOSTABILITY                 ABSTRACT OF THE DISCLOSURE Liquid  crystals  are  induced  to  assume  a  uniform tilted alignment in the absence of an applied field by treating the surface of a substrate to provide a desired tilted surface microstructure and free hydroxyl groups.  A long chain alcohol having the formula ROH, where R is a carbon chain having at least about 6 carbon atoms therein, is chemically reacted with the tilted surface microstruc-ture and the alkoxy groups derived therefrom are chemi-cally bonded to the microstructure.   Subsequently intro-duced liquid crystals assume a tilted-perpendicular align-ment at a tilt angle of about 0.5° to about 6°. The liquid crystals exhibit a significantly greater photostability than has previously been achieved.  The microstructure is preferably obtained by depositing sequential  layers of SiOx at medium and shallow grazing angles, where x is from 1 to 2, with the substrate rotated 90° between deposi-tions.

Title: Drive mechanism
Inventor: HIRMANN GEORG
IPC: F16H47/02
Filed: 1987-10-14
Granted: 1991-10-22
Abstract: Abstract:          The drive mechanism for a rotating part, in particular a vehicle axle, possesses at least one digital-mechanical drive comprising an active wedge and means, which as determined by their design or optionally can be powered by various forms of energy, and which act directly or via energy storage reservoirs to produce impulses which are proportional to the linear or angular displacement of the drive.  One such drive mechanism is used in muscle-powered vehicles or in stationary mechanisms.  It consists of a mechanical impulse drive which as determined by the design or optionally can be powered by muscle power and/or a gaseous pressure medium.  In such a drive a pump (6) taps off some of the drive energy to fill a pressure reservoir.  A switching valve (19) and a work element permit supplementary pulse force to be supplied from a power-reinforcing unit.  This impulse drive, which is digital in character, provides direct driving power in the form of mechanical impulses generated by muscular effort.  It stores surplus energy and makes it available as required to supplement the muscular effort.

Title: Process for the continuous preparation of acetates
Inventor: CANONGE MICHEL
IPC: C07C67/03
Filed: 1988-02-22
Granted: 1992-07-28
Abstract: ABSTRACT OF THE DISCLOSURE          PROCESS FOR THE CONTINUOUS PREPARATION OF ACETATES      The invention relates to a process for the continuous preparation of acetates by a transesterification reaction in the homogeneous liquid phase in the presence of a catalyst selected from metallic alcoholates.  The process comprises more particularly the introduction of the catalyst into a reactor (R) and the introduction of the reagents, formed by an acetate (I) and an alcohol (II), into a distillation column (D1) surmounting the reactor (R) and operating at a pressure (P1) identical with that in (R).  The acetate (III) formed is withdrawn from (R) mixed with the catalyst, which is separated and recycled in (R).  An azeotropic mixture (M1), comprising the acetate (I) and the alcohol (IV) formed, emergences at the head of (D1) and feeds a distillation column (D2) at a pressure (P2) lower than (P1), so as to produce at the head of the column an azeotropic mixture (M2) depleted in alcohol (IV), the mixture being recycled in (D1).  The process permits the use of relatively humid reagents and alcohols of low reactivity, more particularly secondary alcohols (Fig 1).

Title: Method of connecting a cordless telephone by radio
Inventor: MAKINO MASAYUKI
IPC: H04W48/04
Filed: 1988-07-15
Granted: 1991-07-23
Abstract: ABSTRACT OF THE DISCLOSURE A method of connecting a cordless telephone by radio without using control channels selects priority radio channels from radio channels which are shared by cordless telephones and assigns each of them to a respective one of the cordless telephones. So long as the priority radio channel assigned to any of the telephones is not occupied by another telephone, that telephone uses it. A portable unit of the telephone is allowed to enter into a call origination flow in response to a call origination request only after confirming that an incoming calling signal is not being sent over the priority radio channel from a fixed unit which is associated with the portable unit. Even when a call origination request occurs before a radio connection for an incoming call, the fixed and portable units are prevented from tuning to different radio channels without the need for a control channel.

Abstract: ABSTRACT           Catheter Calibration Device A calibration device to be used in calibrating a separate catheter of the type having a catheter tube through which light can be propagated to an end portion of the catheter tube, includes a calibration element defining a cavity extending along a cavity axis to an open end that has a size and shape adapted to receive the end portion of the catheter tube for calibration purposes.  A body of resiliently deformable material with which to hold the catheter tube and thereby retain the end portion within the cavity is retained in generally fixed proximity with the open end of the cavity by a retainer member, and a channel-defining portion of the body of resiliently deformable material defines a longitudinally-opening channel generally aligned with the cavity axis that has a size and shape adapted to receive the catheter tube in an interference fit.  The channel receives the catheter tube by movement of the catheter tube into the channel radially after the end portion of the catheter tube has been placed into the cavity, and it inhibits movement of the catheter tube axially to thereby inhibit movement of the end portion within the cavity.

Granted: 1993-11-23
Abstract: ABSTRACT OF THE INVENTION      An apparatus and method for detecting vertically or horizontally oriented underground electrical conductors such as electrical wiring or rails in tunnels, thin conducing ore veins surrounded by less conducting rock, or boreholes filled with conductive water or lined with a conductive casing.  The apparatus includes a surface or downhole transmitter and a downhole receiver connected to a coherent frequency source unit by fiber optic cables.  The source unit generates two phase synchronized frequency signals in the range of one hundred to three hunderd kHz.  The receiver includes a vertical or horizontal magnetic dipole antenna, e.g. a ferrite rod antenna, and the transmitter includes a vertical or horizontal magnetic dipole antenna in the downhole configuration or at least one long cable or loop antenna in the surface configuration.  The method includes generating a first electromagnetic field which induces current flow in the electrical conductor surrounded by the less conducting rock and then detecting a component of a second electromagnetic field generated by the induced current flowing in the conductor, as a received signal at the receiver.  The received signal is processed by synchronous detection in the coherent frequency source unit so that phase shift and amplitude data can be extracted from the received signal.  The method can also be used to determine if the distance separating two drillholes is constant. In this case, the preferred operating frequency is above 10MHz.
