Patent CA-2328031-A1 (CA)
Inventor: ELLIOTT-MOORE PETER
IPC: F04B9/117
Filed: 2000-12-12
Abstract: An energy recovery device comprises at least one cylinder, a piston slidable in the cylinder, first valve means for selectively connecting one end of the cylinder to waste liquid at a first relatively high pressure and to drain and second valve means for allowing feed liquid to enter the other end of the cylinder at a second lower pressure via a feed liquid entry port and to be discharged via a feed liquid discharge port from said other end of the cylinder in response to movement of the piston caused by waste liquid entering said one end of the cylinder. Also, means, such as a rod which extends from the other end of the cylinder and into but not through the piston, ensures that the area of the piston acting on the feed liquid is less than the area of the piston acted upon by the waste liquid so that the piston acts as a pressure intensifier to discharge feed liquid through the feed liquid discharge port at a higher pressure than the pressure of waste liquid entering said one end of the cylinder.
Patent CA-2331119-A1 (CA)
Inventor: NEWMAN MICHAEL D
IPC: F25D17/06
Filed: 2001-01-16
Abstract: An apparatus for the chilling or freezing of items, particularly food items includes an entrance module, and exit module and may include one or more intermediate modules. The modules may be connected in order to provide an optimal solution in a food freezing or chilling process. Each module includes at least a portion of a belt for conveying items and a motor driven impeller for circulating a stream of cryogenic gas around the items.  The velocity of the stream of cryogenic gas is increased through the use of one or more impingers creating impingement jets above and below the belt.  The impinger may be a plate having a series of holes or it may be a seri es of channels. The configuration of the impinges effects the rate of heat transfer from the cryogen to the items. A sprayer for spraying liquid cryogen into the impingement jets to provide an immediate freezing of the surface of an item. Baffles between modules enable the user to control the flow of cryogen and the pressure differential between modules. A pneumatically actuated ball valve is used to vibrate the impingers to remove snow and ice. The vibrator may be driven by compressed vaporized liquid nitrogen from the same source as that used to cool and/or freeze food items.

Abstract: A mobile communication device containing voice recognition capability is first enabled to perform voice recognition (102). The user then speaks the name of the party the user wishes to call (104), the name corresponding to a record the user has programmed into a memory of the mobile communication device. The mobile communication device then uses the output (106,1 of the voice recognition process to search the memory for a corresponding record (108). The record contains at least two calling numbers, each associated with a different mode of communication, such as dispatch and telephone communication. For a brief period of time after locating the record, the mobile communication device waits (118) for the user to initiate a call in the first communication mode (120) by, for example, pressing a dispatch call button (124). If, after a preselected duration of time has passed and no input is received from the user, the mobile communication device defaults to a second communication mode and makes a call (122).

Patent CA-2378843-A1 (CA)
Title: Float valve reset device
Inventor: HILDEBRAND JOHN R
IPC: F16K31/26
Filed: 2002-03-25
Abstract: The invention provides a device for dislodging a float member from the valve seat of a float valve, particularly in the container of a gas scrubber which is used to separate liquid from a gas carrying such liquid. The device utilizes an annular collar which is secured to the container at the gas outlet and which will allow gas to pass therethrough. A  bushing is provided above the collar and an elongated rod reciprocally extends through the bushing and the collar so that one end of the rod can be brought info contact with the float member. A lever mechanism is provided for effecting movement of the rod and in particular for bringing the one end thereof into force applying contact with the float member whenever it is stuck to the valve seat. By applying the desired force to the float member through the lever and the rod it is possible to dislodge the float member without disassembling the float valve itself.   Once the float member has been dislodged the lever is moved in the opposite direction to move the rod away from the float valve so that the valve can then operate in a normal fashion. The device of the invention can be included with new float valve assemblies or it can be retrofitted as desired.
