Title: Shaft mounted and impeller mounted pumping sleeve and bushing
Inventor: RAMSAY THOMAS W
IPC: F04D29/04
Filed: 1994-06-20
Abstract: The present invention relates to a Shaft-Mounted and Impeller-Mounted Pumping Sleeve and Bushing.   Various devices have been previously proposed for relieving the pressure inside the stuffing box of a pump.  In practice, however, these devices have proven to be inefficient and expensive to install.   Such devices use a centrifugal force to displace the fluid by the use of a repeller. They do not perform the following functions:          A.  circulate the fluid through the stuffing box B.  regulate pressure in the stuffing box C.  allow for any impeller adjustment as the impeller wears It is an objective of the present invention to avoid or minimise one or more of the above mentioned disadvantages.

Title: Galled joints made with electric heating
Inventor: LINZELL GEOFFREY R
IPC: B23K20/12
Filed: 1993-01-11
Abstract: The invention, the subject of our International Application PCT/GB 91/00950 provides a method of securing against lateral motion two bodies held in face-to-face asperity contact, thereby to make a join between the two bodies, in which method there is inserted into the interface between the two bodies a material that on minimal initial lateral relative motion of the two surfaces promotes rapid but controllable "galling" between the two surfaces, this galling binding the surfaces against further such motion. The present invention relates to improvements in galled joints generally, as well as more specifically both to an improvement of our earlier Application's method to facilitate its use over a wider range of interfacial conditions, and also to an addition of that method to permit in some favourably configured joints the converting of the galled contacts therewithin into actual intermetallic diffusion bonds across the interlocked (joined) faces to form continuous welds. The invention proposes that, while and/or after a galled joint is formed, an electric current be passed across the joint. if the current is provided during joint formation then the supplied external mechanical energy is supplemented by the electric current energy so as selectively to heat and soften the touching asperities, enabling them to deform and flatten more rapidly to bring other smaller asperities nearby into contact and thus increase the number of gall sites. If the current is provided after joint formation, then it is believed that it results in the stimulation and/or acceleration of the formation of diffusion bonds across the opposed faces of the joint.

Patent CA-2129708-A1 (CA)
Title: Fiber recovery system and process
Inventor: BONEY JOHN A JR
IPC: D21B1/02
Filed: 1994-08-08
Abstract: ABSTRACT OF THE DISCLOSURE      A system for recovering fiber from sludge by-products generated in a pulp and paper mill.  Initially, heavy materials are separated from a sludge flow, with the flow thereafter separated into first and second components.          High grade fiber is recovered from the first component by centrifugal cleaners and also by optional fine pressure screens.  The second component is forwarded to a refiner which breaks-down the second component to form a low grade pulp.  In addition, after removal of the high grade fiber, remnants from the first component flow  are forwarded to an additional separator such as a liquid cyclone, which removes sand, grit and ash, and thereafter the remnants of the first component can be sent to the refiner for forming a low grade pulp.  Thus, the sludge is essentially separated into four components including: (1) high grade pulp; (2) low grade pulp; (3) heavy materials; and (4) sand, grit and ash.

Patent CA-2130713-A1 (CA)
Title: Heavy duty electrical connection system
Inventor: YARBROUGH GARRETT S
IPC: H01R13/645
Filed: 1994-08-23
Abstract: ABSTRACT   The present invention serves to prevent severe injury, loss of life or damage to expensive equipment by creating a system in which the conductors of a plug and the conductors of a receptacle can only be arranged, one with respect to the other, in a unique rotational manner depending upon the intended electrical rating of the plug and receptacle.  The resulting plug will mate only with a receptacle having that same configuration.  A separate indexer is disposed between the plug body and the conductor assembly to the conductors in the plug to prevent entry of the plug into a differently indexed receptacle.  A polarizer in the receptacle fixes the conductor assembly of the receptacle in the same manner as the plug, to allow the plug and receptacle to be mated together when the receptacle is wired for the same electrical rating as the equipment to be energized by the plug.  Visual means of identifying the rotational attitude of conductors is provided whereby the electrical rating of the plug or receptacle can be easily identified.  The visual means of identification may include color as well as printed coding information.
