Patent CA-2000790-C (CA)
Inventor: NEWKIRK MARC STEVENS
IPC: B22D19/14
Filed: 1989-10-13
Granted: 2001-05-01
Abstract: The present invention relates to the formation of a macrocomposite body by spontaneously infiltrating a permeable mass of filler material or a preform with molten matrix metal and bonding the spontaneously infiltrated material to at least one second material such as a ceramic or ceramic containing body and/or a metal or metal containing body. Particularly, an infiltration enhancer and/or infiltration enhancer precursor and/or infiltrating atmosphere are in communication with a filler material or a preform, at least at some point during the process, which permits molten matrix metal to spontaneously infiltrate the filler material or preform. Moreover, prior to infiltration, the filler material or preform is placed into contact with at least a portion of a second material such that after infiltation of the filler material or preform, the infiltrated material is bonded to the second material, thereby forming a macrocomposite body.

Abstract: An optical switch includes at least one input optical semiconductor waveguide; two output optical semiconductor waveguides connected at a branch point to the input optical waveguide and diverging from the branch point with a preset angle .theta. (degree) therebetween; and a refractive index controlling section disposed in position on at least one of the output optical waveguides and apart from the branch point, for electrically pausing the refractive index of the output optical waveguide to be reduced. A light attenuating layer for preventing radiation mode light leaked from a portion near the branch point to the outside of the optical waveguide from being re-combined with guided mode light in the output optical waveguide is disposed between the two output optical waveguides.      The refractive index controlling section is formed so that a length from the physical branch point between said two output optical waveguides to an output end portion of the refractive index controlling section may be set equal to or larger than 100 .theta. 8/cos (.theta./2) µm.      A distance between the nearest portions of the refractive controlling sections of the output optical waveguides is set to be equal to or less than twice a spot size so as to improve the extinction ratio and excessive loss. The optical switch of this invention can be applied to a Y-junction type and X-junction type, and the refractive controlling section can be disposed on each of the branches or may be disposed on selected two of the branches. In the X-junction type optical switch, the refractive index controlling section may be adequately disposed on one of groups of branches which make an angle of (180°-.theta.°).

Title: Pipeline repair sleeve assembly
Inventor: SAVARD DONALD D
IPC: F16L55/172
Filed: 1989-12-07
Granted: 1996-11-05
Abstract: The assembly comprises a pair of semi-circular steel shells. The inner surface of one shell forms a circular recess.          A flat cylindrical annular seal element is seated in and fills the recess.  The element is resilient and deformable.   It has concentric protruding ribs on its top and bottom surfaces.  The seal element is positioned to circumscribe a leaking small hole or crack in the wall of an internally pressurized pipeline.  The shells are then circumferentially clamped against the pipeline to cause the element to seal around the leak and to effect tight shell-on-pipe  contact.   The  steel  side wall  of  the  recess confines the compressed seal element.   The side edges of the shells   are   then   welded   together   longitudinally   and circumferentially to create a permanent pressure vessel sealing and containing the leak.

Title: Washable diaper with absorbent liner
Inventor: PEREZ SAM S
IPC: A61F13/15
Filed: 1990-02-02
Granted: 1992-08-18
Abstract: ABSTRACT         An improved washable diaper is provided with an absorbent liner that is folded within the diaper during use for improved absorbency and, following use, extends from the diaper for improved efficiency of cleaning and drying.  An additional liner may be secured to the liner in cases where extra absorbency is required, such as for overnight use, and removed from the liner for cleaning and drying.  The liners provide additional layers of absorbent cloth while their separation from the diaper body following use avoids the difficulties of cleaning and drying presented by a number of cloth layers permanently secured to one another.

Title: Well completions
Inventor: SZARKA DAVID D
IPC: E21B41/00
Filed: 1990-05-28
Granted: 1995-02-07
Abstract: A well is completed by cementing a casing string in place in the well.  A jetting tool assembly is run into the casing string on a tubing string.  The jetting tool assembly engages a sliding sleeve of a casing valve and slides the sliding sleeve to an open position uncovering a plurality of housing ports in the casing valve housing in which the sleeve is received.  Then, disintegratable plugs are hydraulically jetted from the housing ports to communicate a subsurface formation adjacent the casing valve with an interior of the casing string. Preferably, prior to opening the sleeve and hydraulically jetting the plugs, residual cement is drilled from the casing string, then further resi-dual cement is hydraulically jetted from the casing valve, and then the casing valve is backwashed by reverse cir-culation.

Title: Apparatus for controlling a power supply of an electric machine in a vehicle
Inventor: FUJIWARA RYUHEI
IPC: B60R16/03
Filed: 1990-10-30
Granted: 1995-11-28
Abstract: An apparatus for controlling a power supply of an electric machine in a vehicle comprises primary and secondary power supplies for supplying an electric power to the electric machine. In non-driving state of an engine, the primary power supply is selected as a power supply for the electric machine when an electric power consumption is over a predetermined value, and the secondary power supply is selected when the consumption is below the predetermined value. Therefore,  the absentee receiving of facsimile information,  the absentee recording of telephone message, etc. are carried out, even in a state of turning-off of an ignition switch. The secondary power supply is used mainly in the case that the electric machine is in waiting mode, so that the complete exhaustion of the secondary battery can be prevented.

Title: Hydronic heating water temperature control system
Inventor: FIEDRICH JOACHIM
IPC: G05D23/13
Filed: 1990-11-07
Granted: 1994-09-06
Abstract: HYDRONIC HEATING WATER TEMPERATURE CONTROL SYSTEM   ABSTRACT OF THE INVENTION      A three-way modulated diverting valve is provided in the return line to the boiler of a hydronic heating system between the heating loop return and the boiler return, the valve having its input from the heating loop return, one output to the boiler return and the second output to the heating loop supply, so that the valve diverts some of the cooler return water to the boiler hot supply water, diluting the supply water to reduce the temperature of supply water that feeds the heating loop; and the valve is modulated by a feedback signal representative of the temperature of the diluted supply water. In a preferred embodiment, the feedback modulation is accomplished using a non-electric thermostatic actuator head that drives the valve stem and is controlled by a capillary temperature sensor, the sensor bulb being immersed in the diluted supply water or clamped to the supply line next to the heating loop supply so that it is at the temperature of the diluted supply water.  In operation, capillary fluid in the bulb expands with temperature applying a pressure force through the capillary to the actuator head which drives the valve stem, and so the diverting valve is modulated to increase or decrease the flow of return water to dilute the supply water as necessary to maintain the diluted supply water temperature at a predetermined value.

Granted: 1998-08-18
Abstract: A vehicle includes a carriage suspended with wheels from an overhead track. A suspension mechanism supports a passenger or cargo car from the carriage. The suspension mechanism includes horizontal pivot joint that allows the car to swing about a horizontal axis when traversing bends. A sliding connection between the car and the pivot joint permits the car to displace horizontally relative to the pivot axis. A motor rotates a screw thread mechanism to produce such displacement. A sensor detects inclination of the car relative to vertical in response to uneven weight distribution or wind forces, but is not responsive; to centrifugal forces and normal swinging of the car at bends. The sensed inclination of the car may be displayed on a monitor, and controls permit the motor to be actuated to displace the car in a direction in which gravity applies a torque to the car that reduces undesired inclination.
