When the flapper valve (10) pivots to the open position, the lower tube member (110) moves adjacent to and forms a seal with the uppe r tube member (108), forming an unobstructed internal bore.
Patent CA-2390468-A1 (CA)
Title: A pultruded part reinforced by longitudinal and transverse fibers and a method of manufacturing thereof
Inventor: DAVIES LAURENCE W
IPC: B29C70/08
Filed: 2002-06-12
Abstract: A method for forming a pultruded part includes collating reinforcing fibers by providing a first layer of reinforcing rovings extending in the longitudinal pultrusion direction, applying onto the first layer an intermediate layer of reinforcing fibers at least some of which include at least portions thereof which extend in the transverse direction and covering the intermediate layer with a second layer of rovings extending in the longitudinal direction. To the collated fibers is applied a resin so as to permeate through the layers and the materials are passed through a die to set the resin. The first and second layers are arranged to form first and second opposed surfaces of the part with the intermediate layer therebetween.  The resin is a two part urethane resin which has sufficient strength to prevent the fibers from the first and second layers at the first and second surfaces respectively from breaking through the surface on bending of the wall thus allowing the use of the rovings at the surfaces with the transverse fibers therebetween so that the transverse fibers can be formed from loose or chopped fiber material from rovings rather than more expensive mat.
Patent CA-2391104-A1 (CA)
Inventor: MAKIN DAVID
IPC: F16D1/08
Filed: 1993-07-27
Abstract: A shaft 44;144,145 is conventionally driveably connected to a bore1 46,146 by a steel key of rectangular cross-section. Where the shaft is of smaller diameter than the bore, a slotted nylon sleeve is fitted between them and a tall steel key extends through the slot. Failure of both standard and tall keys can occur for various reasons. A unitary component 50,162,163 of suitable plastics material or non-ferrous metal is therefore proposed. This component essentially includes an integral key 56,174 of curved cross-section adapted to engage in a mating keyway 176 formed in the bore. Where the shaft 44 and bore 46 are nominally of the same diameter, the component 50 consists also of an integral key 52 of rectangular cross-section adapted to engage in the conventional keyway 48 in the shaft. Where the shaft 144, 145 is of smaller diameter than the bore 146, the component 162, 163 also includes a sleeve 164 with the key 174 of curved cross-section formed on its outer periphery, and a keyway 170 of rectangular cross-section formed in its inner periphery and adapted to be driveably connected by a separate standard key 171 to the conventional keyway 148,149 in the shaft. The component is useful in the flange-mounting of different electric motors on off the-shelf gear units.
Patent CA-2397538-A1 (CA)
Inventor: HENRY ROGER JOHN WILTON
IPC: B42F9/00
Filed: 2001-01-15
Abstract: A clamp for clamping sheets and like material has opposed elongate clamping jaws (2, 4) mounted for pivotal movement between a clamping condition and a relatively open, released condition, and a latch device for effecting moveme nt of the jaws (2, 4). The latch device comprises a member (12) of channel section within which an upper part of the jaws (2, 4) is mounted whereby opposite sides of the member (12) cooperate with the two jaws (2, 4), and latch levers (26) pivotal between a stable latched position and a released position. The latch levers (26) are linked to the jaws (2, 4) by a screw mechanism (22) and cooperate with the member (12) such that movement of the latch levers (26) to their released positions effects relative movement between the jaws (2, 4) and member (12) to enable opening of the jaws (2, 4) . Adjustment of the clamping and open condition of the jaws (2, 4) is effected  by rotation of the latch levers (26) about the axis of the screw mechanism (22).

Filed: 2000-04-18
Abstract: A binder (100) for releasably retaining loose-leaves. The binder has a front  cover (44) that lies flatly beneath its back cover (40) when the binder is open 360 degrees. The rings (46) of the binder can rotate around an edge of the flatly-folded cover to enable loose-leaves to lie flat above and below t he cover. The binder also has a skeleton (50) with a minimal cross-section spin e which may be partially or completely embedded in a cover and rotates in relation to parallel front and back covers when the binder is open 360 degrees. The front cover, middle cover and back cover are connected in a way  so that they do not interfere with the rotation of the rings. Mechanisms (51 ) to open and close the rings of the skeleton to allow addition or removal of loose-leaves, and ring shapes to optimize or stabilize the capacity of the binder during operation are also disclosed.

Title: Interactive dialogues
Inventor: ATTWATER DAVID JOHN
IPC: G10L15/22
Filed: 2001-07-19
Abstract: An interactive dialogue apparatus generates prompts and receives responses which it processes and stores response data. Progress of the dialogue is controlled using a state model which is parsed, comparing transition conditions with the stored response data, stopping at a state for which no edge condition is satisfied. Each time a fresh response is received, the mod el is reparsed from the start. Prompts are generated by reference to a state history, being selected by finding the longest match between the history and  state sequences associated with stored prompts. Prompts are compared so that  the dialogue may be terminated in the event of repetition.

Title: Ship lock electrical energy generation
Inventor: DESY NORMAND
IPC: E02B9/00
Filed: 2002-12-05
Abstract: A ship lock utilizes a hydraulic turbine and/or pump-turbine to regulate the discharge flow rates through the ship lock to an approximate constant value during the majority of the water transfer cycle resulting in a diminishing of total energy of head losses and to enable the recuperation of the unused hydraulic energy for generation as electricity.      The difference in water levels on opposite sides of the ship lock constitutes potential hydraulic energy. By regulating the discharge, the total head losses over a given period of time diminish very significantly, thus giving an opportunity for optimization of hydraulic energy recuperation.

Title: Multiple output dynamically regulated charge pump power converter
Inventor: GARTSTEIN VLADIMIR
IPC: H02M3/07
Filed: 2001-08-27
Abstract: A charge pump power converter efficiently provides electrical power by dynamically controlling a switch matrix (48) of the charge pump (44). Instea d of open-loop oscillator-based control, a dynamic controller (50) provides power upon demand by sensing the output voltage and changing the operating frequency of the charge pump in response. Moreover, this closed-loop dynamic  control intrinsically voltage regulates the output voltage of the charge pum p power converter without the inefficient addition of a step-down voltage regulator, downstream of the power converter. Additional efficiencies are achieved through maintaining the voltage ripple across the fly capacitor (Cf ) and/or the load capacitor (Cl). Also, a three-state control scheme is used t o charge the fly capacitor, wait for the output voltage to drop to a predetermined level, and discharge the fly capacitor. Furthermore, a multipl e- output charge pump power converter provides multiple voltage levels for devices such as portable communication electronic devices.
