Patent CA-2133716-A1 (CA)
Inventor: KUBOTA YOUSUKE
IPC: G01F1/58
Filed: 1994-10-05
Abstract: An electromagnetic flowmeter comprises a cylindrical support. A pair of coils are positioned at the outer surface of the cylindrical support, spaced approximately 180° apart.      The cylindrical support is coaxially mounted within a cylindrical magnetic path, which defines a space for the coils between the magnetic path and the cylindrical support.      The magnetic path has two ends, each engaged by a flange.      The flanges include bosses, which together with the cylindrical support and magnetic path serve to position the coils. A conduit is mounted within the support, and a housing encloses the support, the coils, and the conduit.      The length of the housing is greater than the length of the conduit, defining a gap between the housing and the conduit.

IPC: C07C45/66
Filed: 1993-04-07
Abstract: An aldolisation-dehydration process is disclosed for converting an aldehyde, e.g. n-valeraldehyde, to a substituted acro-lein, e.g. propyl butyl acrolein (2-propylhept-2-enal). Aldolisation and dehydration are effected in a stirred tank reactor (16; 111) using an alkali catalyst, such as sodium hydroxide. A reaction product stream (23; 113) containing both organic and aqueous phases is distilled (in column 25; 123) to yield a heterogeneous azeotrope containing water and aldehyde. On condensation and phase separation the lower water layer (34; 150) can be discharged from the plant without the need for neutralisation. From the bottom of the distillation zone a mixture (36; 157) of substituted acrolein and alkali catalyst solution is obtained. The substituted acrolein is recovered as product (45; 173), while the catalyst solution (47; 175) is recycled to the aldolisation reactor. Part (49; 181) of the catalyst solution is purged to control the level of Cannizzaro reaction products.

Abstract: A device (3) for indicating the operating state of a linear actuation valve (5) comprises a mounting plate (9) having a rectilinear slot (11) therein for slidably receiving a perpendicularly extending follower stem (6) fixed to a follower nut (4). The nut (4) is threaded on to the exterior of a sleeve (7) which is mounted for conjoint rotation with the hub of a hand wheel (2) of the linear actuation valve. Engagement of the follower stem (6) with the slot (11) prevents rotation of the nut (4) and provokes it to move axially relative to the sleeve (7). The mounting plate (9) also includes means for fixing sensors (15) and (16) to the plate for detecting arrival of the follower stem (6) moving along the slot in either of two positions to be detected.

Patent CA-2172691-A1 (CA)
Title: Wiring clip
Inventor: LAUGHLIN RAYMOND SCOTT
IPC: F16L3/22
Filed: 1996-03-26
Abstract: A plastic clip is fastened to a metal or wood stud to support and position multiple runs of various types of wiring or cabling. The clip keeps the wiring in compliance with the National Electric Code (NEC) Section 300-4. The clip includes a base with a short gauge flange at one end to engage the face or front corner of the stud when the base is fastened to the side of the stud. Projecting directly from the base or a neck extension of the base are two spaced hinge arms, which extendat an angle to each other. Each arm includes two interior opening cable receiving slots. Between such slots is a bulbous thinner wall pressure body section which in its undistorted condition partly restricts the openings of such slots. A similarthinner wall section forms the interior or base side of the innermost slot in each arm. When wiring or cabling is inserted in the slots when the hinge arms are open it is moderately gripped by the clip so that it is not loose, thus reducing the weight and strain of the wiring or cabling at a electrical box or other termination. The end of one arm has a projecting catch which snaps into a mating slot on the end of the other, when the arms are closed, and when closed, the bulbous thinner wall pressure body sections distort firmly wrapping and gripping the wiring or cabling. One embodiment may be also secured to the stud by the edges of different size holes in the web of the stud.

Abstract: A catalytic detector for a flammable gas comprises a substrate and a sensing structure suspended from the substrate. The sensing structure has a combined heating element and temperature sensing element in the form of a layer-deposited electrically conductive track terminating in at least two electrically bridging leads. A catalytic bead is deposited over the temperature sensing element and that portion of the substrate which is directly beneath the sensing structure is etched away so as to isolate thermally the sensing structure with the temperature sensing structure being supported by the bridging leads. The electrically conductive track is sandwiched between a substrate adhesion layer for facilitating adhesion of the conductive track and a superstrate diffusion barrier layer. The invention extends to a method of manufacturing a gas detector and a sensing structure.
