Patent CA-2126482-A1 (CA)
Inventor: BURCH RONALD H
IPC: A22C25/00
Filed: 1994-06-22
Abstract: ABSTRACT A fluid cutting system of improved configuration provides a high-velocity fluid that is rotated about a first axis (preferably a horizontal axis) on a moving trolley. The trolley is rotationally supported about a second axis (preferably vertical). The trolley travels upon a pair of arc-shaped tracks and is driven by a motor drive. The trolley has a pair of arc-shaped tracks that support the fluid jet nozzle. The fluid nozzle is thus rotatable about two axes, thereby emitting a high-pressure stream of fluid for adjustable cutting. A workpiece positioning frame has a fish section holder that can be elevated or moved laterally with respect to the cutting system.

Title: Working a natural or synthetic hard stone such as a gemstone
Inventor: BEAL DAVID W
IPC: B28D5/02
Filed: 1994-12-12
Abstract: ABSTRACT          For blocking or polishing a natural or synthetic stone having a Mohs hardness greater than 5, a blocking head has a body, a mounting member 9 which can move vertically with respect to the body, and a rotary spindle driven by a motor 12.  The mounting member 9 is carried by a leaf spring 22 whose position is altered by a parallel linkage 23, 25, 26 whose arm 26 is driven by a motor.  In this way, the spring 22 can for soft landing apply an upwards bias opposing the gravitational force of the mass of the mounting member 9.  When the stone 3 is in contact with the scaife, the deflection of the spring 22 measures the force on the stone 3, and this deflection is detected by an LVDT 15.          Subsequently, the spring 22 can apply a downwards bias to augment the working force.  A microprocessor is responsive to the output of the LVDT 15 and controls the motor so that the force applied to the stone 3 complies with a predetermined programme.

Title: Distributed fiber optic sensing system
Inventor: CRAWFORD BRIAN B
IPC: G01H9/00
Filed: 1993-03-05
Abstract: A distributed fiber optic sensing system for detecting mechanical, acoustic or ultrasonic disturbances is disclosed. This sys-tem is optimized for use as an intrusion detection system in security applications. Light is launched into opposite ends of a sen-sing fiber loop (24) such that two beams circulate through the loop in opposite directions and then recombine to produce an inter-ference pattern on a photoelectric detector (30). Disturbances of the sensing fiber loop produce corresponding changes in the interference pattern and thereby the signal level at the detector. The changes in the electrical signal from the detector are interpret-ed (28, 29) to provide alarms when the sensing fiber loop is impinged upon by intrusive disturbances, and to provide location of disturbances along the loop. Means (33, 31) are incorporated to decode uniquely coded sonic or ultrasonic signals from personal transmitters (37) borne by authorized personnel approaching the sensing fiber loop. A remotely activated system disturber (25) is affixed to the sensing fiber loop which, when activated by an operator, provides positive confirmation of sensing loop continuity and system operability.

Title: Apparatus for discouraging animal disruption of flowerbeds and the like
Inventor: WILKINSON CURTIS
IPC: A01M29/00
Filed: 1995-07-04
Abstract: Gardeners' have employed many methods to keep cats and other animals from enter-ing and causing disruption to flowerbeds and the like. Such methods have included fences, electrified ground panels and the deliberate cultivation of plants noxious to the animals. The invention disclosed herein details a simple yet effective alternative device to those currently available, that does not, in any way, cause harm to the animal and which is comprised of a motion detector having a sensitivity adjustment control for setting the range within which detection takes place. The motion. detector controls the operation of a water flow control valve which is normally biased closed pending receipt of an electrical signal from the detec-tor, which signal is generated by the detector in response to movement within the detector's operating range. Upon receipt of the detector signal a solenoid on the water flow control valve activates, biasing the valve open and permitting water flow from a conventional garden hose supply, through the valve to a perforated spray head. The spray head may be arranged around the perimeter of a flowerbed to create a "wall" of water, or may be nothing more than a simple oscillating or rotary sprinkler.  The duration of the water spray may be set utilizing a timer function of the motion detector, which timer limits the duration of the detector's elec-trical output signal and hence the water spray.

Patent CA-2160411-A1 (CA)
Inventor: RHEAULT ALAIN
IPC: B63B59/08
Filed: 1995-10-12
Abstract: A weedless system has been developed for personal watercraft which obtain their power by using jet propelled water pumps.  The unique weedless system has a number of elements which help to reduce weed congestion in the jet pump.          Firstly, a plurality of downwardly directed grates, which terminate at the head of the ride shoe, are used such that weeds striking such grates will tend to slide off the grates rather than become embroiled around them.  In addition, between the venturi and the steering nozzle there is located a butterfly valve which can be manually closed or opened by the operator.  Closure of the butterfly valve creates a rotating movement of the water within the jet pump to provoke shaking, cutting and dislodging of weeds that go through the great barrier.  The weeds then pass out through the water inlet back through a weed outlet passage or become pulverized such that they will pass safely past the jet pump when the valve is reopened and the boat regains normal efficiency.
