IPC: G08B13/26
Filed: 1991-12-16
Granted: 1998-08-18
Abstract: A circuit for controlling and stopping the motion of dangerous moving parts is disclosed.  The circuit includes an antenna (16) connected to a moving part (18) and coupled to a tunable circuit (10) for controlling a safety equipment (32). The antenna (16) provides a variable lumped capacitance parameter within the tunable circuit (10). This lumped capacitance parameter is variable in response to an operator's body capacitance produced when the operator comes within a predetermined critical proximity to the moving part (18).  This variation in lumped capacitance serves to tune the circuit (10) at or near a point of resonance to thereby enable an RF signal to pass through the tunable circuit (10) at a detectable level which is subsequently processed to activate the safety equipment (32) for controlling and stopping the motion of the moving part (18) substantially instantaneously.

Granted: 2005-03-01
Abstract: In order to enhance the availability of tools, a multi-function tool includes a handle having first and second ends with the first end having an opening for receiving a screwdriver tip, and the second end having an opening for receiving a tube which is releasably retained in relation to the handle by a collet. The handle has opposed side openings extending from the second end to a point near the collet. The tube is mounted for limited axial sliding movement relative to the handle from a position where one of its ends is retained by the collet to position where it is no longer retained by the collet to position the tube in alignment with the side openings in the handle. The tube is also mounted for pivoting movement when it is in alignment with the side openings to a generally transversely extending position. The tube cooperates with the handle in the generally transversely extending position to define a T-shaped handled for applying increased torque to the first handle end. With this construction, a screwdriver tip is also operatively associated with each of the ends of the tube to project outwardly of the second end of the handle when the other of the ends of the tube is retained by the collet.

Title: Process for preparation of sulphonates
Inventor: ALCOCK KENNETH
IPC: C10M135/10
Filed: 1993-08-07
Granted: 2004-08-03
Abstract: Sulphonates are prepared by the neutralisation of a sulphonic acid with a basic hydroxide or oxide. The process requires the staged addition of sulphonic acid to a reaction mixture comprising basic hydroxide or oxide dispersed in a water/diluent mixture; the reaction mixture is basic throughout the additions of acid and at least until the point of completion of the neutralisation reaction. The basic hydroxide or oxide may also be added in stages. The sulphonate product has low viscosity, low haze and good stability and is essentially chloride free as halide promoters are not utilised in the manufacture of the product.
Patent CA-2143768-C (CA)
Inventor: DEAN ARTHUR L
IPC: H02P25/06
Filed: 1995-03-02
Granted: 1999-12-14
Abstract: This invention pertains to sensorless measurement of electromagnetically induced displacement in actuators and similar units. Primarily, the device imposes a constant frequency and amplitude excitation sine wave on a coil through a fixed impedance of a drive isolation network.      The amplitude and phase of the voltage across the coil fluctuate depending upon the coil's inductance. This variation in the value of the inductance is dependent upon the change in magnetic flux density generated by the coil current and the displacement in air gap between the coil pole and armature. Accordingly, a measurable magnitude of displacement can be controllably imposed upon a system of solenoids. The displacement is thus measured and set without the use of extrinsic sensors.

Title: Improved sprayable portland cement-based fireproofing compositions
Inventor: PERITO RICHARD P
IPC: B05D1/36
Filed: 1995-03-17
Granted: 2005-06-14
Abstract: Sprayable fireproofing compositions for structural members such as steel columns are provided, as well as a method of applying multiple coatings thereof. The compositions comprise a Portland cement-based material, stucco, a high density aggregate and an accelerator. The compositions eliminate the long setting times typical of Portland cement-based materials, and improve the hangability thereof. The product is produced by dry blending a mixture of Portland cement, a high density aggreagte, stucco (calcium sulfate hemi-hydrate) and optionally, a stucco set retarder and shredded polystyrene aggregate. Upon the addition of water, sprayable slurries are formed which can be pumped to the point of application. An accelerator is added in close proximity to the point of injection. The slurries adhere to the structural member in the slurried state and after setting to provide excellent fire and heat protection. Because of the relative quick setting time of the slurry upon spray application, multiple coatings can be applied within the same working day.
