Patent CA-2121152-C (CA)
Title: Chemically sensitive fiber optic cable
Inventor: RAVETTI ROBERT G
IPC: G02B6/36
Filed: 1994-04-13
Granted: 1998-12-15
Abstract: A chemically sensitive sensor (10) capable of detecting changes in concentrations of ions, atoms, or molecules in a fluid environment (38) in which the sensor is immersed or embedded comprises a thin clad optical fiber (26), which is coated with a polymer (34) which is permeable to liquids and which contains a chemically sensitive material, and a light carrying fiber (20).  The polymeric material has the ability to change color and/or absorbance when the concentration of the ion, atom, or molecule in the surrounding environment changes.  The polymer will return to its original color and/or absorbance state once the concentration goes back to the original value.  The color change or absorbance is detected through the core (30) of the optical fiber which is connected to a photodetector (28).  The coupling of the light (22) into the sensing structure is obtained by using a core-only optical fiber (20), surrounded by a clad material (36), in addition to an external light source (24).  Coupling of the external light beam with the polymeric coated fiber is obtained through microbending losses in reverse by spooling the coated fiber around the clad material.   Changes such as pH, metal or other ion concentration,  organic molecule  concentration,  and gas molecule concentration may be detected.

Abstract: A thermally-actuated steam trap comprises a valve casing having an inlet 4, a valve chest 3 and an outlet 5.  A valve seat member 7 with a discharge passage 8 is disposed between the valve chest 3 and the outlet 5.  A temperature control element 9 with an expansible medium 15 sealed therein is disposed within the valve chest 3, and consists of two disk-shaped wall members 11,19, at least one wave-like diaphragm member 14,18 provided between the wall members 11, 19 and a valve member 16 secured to the diaphragm member 18.          Displacement of the diaphragm 14 accompanying the expansion and contraction of the expansible medium 15 causes the valve member 16 to come into and out of a seating engagement with the valve seat member 7 to close and open the discharge passage.  In order to avoid a state of producing a permanent deformation of the diaphragm of low elastic material and not to be affected by repeated use of the diaphragm, the upper surface of the lower disk-shaped wall member 19 has a curved region corresponding to the wave form of the diaphragm member 18.

Title: Magnetic locks
Inventor: SEDLEY BRUCE SAMUEL
IPC: E05B67/22
Filed: 1993-04-16
Granted: 2003-09-02
Abstract: A magnetic key operated lock has an anti-rap arrangement which comprises a magnet pin (13) supported in a bar (16) mounted in a slide member (1). The remote end of the pin (13) fits into an aperture (17) in a locking plate (3) and is pivoted to swing downwards out of the aperture (17) when a correctly coded key is inserted into the lock. The correctly coded key has a re-pelling spot to pivot the magnet as required and before the key attempts to move the slide member from its locked position shown in the figure. Rapping on the face of the lock cannot move the remote end of the magnet pin (13) out of the aperture (17) because it is restrained by its pivoting action from moving laterally out of the locking plate. Another anti-rap arrangement is described with respect to the other drawings and a padlock incorporating both anti-rap arrangements is also described.

Abstract: A self-contained composite roofing batten bar has a layer of adhesive material secured to the bottom or undersurface portion of a roofing batten bar or strip. The adhesive material is tacky or sticky at room temperature and preferably comprises a butyl rubber composition. In view of the inherent tackiness or stickiness of the butyl rubber adhesive composition, one surface of the adhesive material layer is inherently adhered to the bottom or undersurface portion of the roofing batten bar or strip and the other lower or undersurface portion of the adhesive layer is covered by a releasable paper backing strip. When it is desired to use the composite batten bar in order to secure, for example, a roofing membrane to underlying roofing structure, the releasably paper backing strip is simply removed thereby exposing the lower or undersurface portion of the adhesive layer. The batten bar or strip is then able to be mounted upon or atop the roofing membrane at predetermined locations as dictated by the overall roofing installation requirements. The batten bar or strip may be provided with preformed apertures or holes for the reception of suitable fasteners such that the batten bar and roofing membrane assembly may be fixedly secured to the underlying roofing structure or decking.

Title: Force sensing assembly and method for a product delivery system
Inventor: MONCRIEF FRANK
IPC: B31B50/06
Filed: 1996-01-23
Granted: 2007-01-09
Abstract: A force sensing assembly measures a magnitude of a force generated at the tabs (18) in a product delivery system. The product delivery system can be one in which a force is produced at the tabs by the weight of the stack, by a paddle (12) pushing an end of the stack (14), or by another similar type of advancing mechanism. In a preferred embodiment, the force sensing assembly has a pair of tabs connected to a cross-bar (20) which extends across the stack and which is connected to the frame of the feeder through a bell crank (24) at one end and a lever (20) at the other end. The bell crank has one arm connected to the cross-bar (20) and a second arm connected to a load cell (42). The force at the tabs causes the lever and bell crank to rotate, with the force being transmitted through the bell crank, through a spring, and then to the load cell. The load cell generates a force signal which is supplied to a controller for adjusting the amount of force at the tabs. The controller adjusts the force by adding more products to the stack or by advancing the stack closer to the tabs. The load cell preferably has a stopper for preventing an excessive amount of force from reaching the cell.

Abstract: An appliance timer has features to facilitate automated assembly or manual assembly. A timer housing base accepts timer components from two directions, and installation of components in either direction is along a straight axis. A motor in the timer engages a gear train which runs a drive cam. The drive cam imparts motion to a camstack which then engages timer blade switches, and the blade switches operate the appliance. A subinterval is also supplied on the timer to allow periodic operation of a switch without the use of the camstack. The timer also features a quiet manual advance which removes the blade switches from communication with the camstack to allow an operator to select various timer programs without any of the clicking noises that are usually associated with timer program selection. Furthermore, a detent slider is positioned in communication with the camstack to provide a tactile feel for the operator of the timer when selecting between various timer programs.
