Abstract: An illuminated sign construction comprises a main housing and a secondary housing removably fitted at its surrounding frame within the main housing. The secondary housing has a translucent panel and a transparent panel held separated from one another by the frame of the secondary housing to define a pocket in which signage material is fitted between the two panels. The sign construction further includes a lighting assembly within the main housing behind the secondary housing. The lighting assembly comprises a light producing member which casts direct light and a reflector which reflects light from the light producing member at the secondary housing.      The frame of the secondary housing comprises a main frame portion and a frame piece which is releasable from the main frame portion when the secondary housing is removed from the main housing. The frame piece, when released from the main frame portion, opens the pocket in the secondary housing and additionally pulls the signage material from the pocket.

Patent CA-2249157-A1 (CA)
Title: Uniform distribution monoenergetic ion implantation
Inventor: SARKISSIAN ANDRANIK
IPC: H01J37/32
Filed: 1998-10-01
Abstract: A system for implanting ions in an object which has three dimensional topology in a uniform or predetermined pattern is provided by the invention herein. The system includes a vacuum chamber defining an interior space. The interior space includes a first region adjacent to interior walls of the vacuum chamber. The first region being used primarily for plasma protection. The interior space of the vacuum chamber also includes a second region for ion acceleration and the second region is substantially surrounded by the first region. A potential distribution control grid defines the boundary between the first and second regions and the potential distribution control grid is pervious to the passage of ions from the plasma generated in the first region into the second region. An object to be implanted is placed at a predetermined position in the second region and when subjected to a negative voltage charge, draws ions through the potential distribution control grid from the first region into the second region and accelerates them in a uniform manner towards the object to be implanted. The accelerated ions are monoenergetic since they all have the same momentum. The system provides magnetic field to help confine the plasma in the first region but maintains the second region in a relatively magnetic field free state.

Title: Resorbable implant biomaterial made of condensed calcium phosphate particles
Inventor: GRYNPAS MARC
IPC: A61F2/00
Filed: 1997-05-15
Abstract: A resorbable biomaterial for implantation in humans and other animals comprises amorphous or crystalline condensed calcium phosphate of the general formula: ¢Ca(PO3)2!n, where n is 3 or greater and the molar ratio of Ca:P is between about 0.4 and 0.6.

Patent CA-2252936-A1 (CA)
Title: Adjustable height load bearing support structure
Inventor: MACHAEL JAY R
IPC: A47B9/02
Filed: 1997-10-10
Abstract: A counterbalanced adjustable height load bearing support structure (20) with a pretensioning mechanism comprises a pair of pivotable arms (42, 42) each having a free end (44) in engagement with a support assembly (24) and being biased by a torsion spring (40). A lever arm (154) is connected to each torsion spring (40) and exerts a biasing force on the pivotable arm (42) when the lever (154) is rotated, thereby preloading the springs. A cable (122) connects the lever arms and passes over a central bushing (170). The bushing (170) receives a threaded shaft (150) which may be turned to move the bushing and thereby adjust the tension in the cable. Because the cable (122) is capable of sliding engagement with the bushing (170), tension in the cable is substantially uniform throughout its entire length and thus the resultant forces on the lever arms (154) are approximately equal, whereby binding or racking of the support assemblies (20) is minimized as the support surface (32) is raised or lowered.

Title: Method and apparatus for improving the voice quality of tandemed vocoders
Inventor: RABIPOUR RAFI
IPC: G10L19/06
Filed: 1997-11-05
Abstract: In recent years, the telecommunications industry has witnessed the proliferation of a variety of digital vocoders in order to meet bandwidth demands of different wireline and wireless communication systems. The rapid growth in the diversity of networks and the number of users of such networks is increasing the number of instances where two vocoders are placed in tandem to serve a single connection. Such arrangements of low bit-rate codecs can degrade the quality of the transmitted speech. To overcome this problem the invention provides a novel method and an apparatus for transmitting digitized voice signals in the wireless communications environment. The apparatus is capable of converting a compressed speech signal from one format to another format via an intermediate common format, thus avoiding the necessity to successively de-compress voice data to a PCM type digitization and then recompress the voice data.
Patent CA-2257319-A1 (CA)
Inventor: GAGE WILLIAM ANTHONY
IPC: H04W24/08
Filed: 1998-12-30
Abstract: A radio link adapter for wireless transmission of multimedia data through a communication link between a radio access network (RAN) and a mobile station (MS), is provided. The information flow is constantly monitored to determine the class of service requirements and for allocating a pair of adapters designed to fit the respective class of service requirements. A connection end may be initially established in the RAN or in the MS. An analyser monitors the link, detects the class of service required, and dynamically allocates the adequate adapter to the connection. There is no need to recreate the connection when selecting the adapter for transporting various classes of service and therefore, the transport of the information flow is optimized while maintaining the end-to-end quality of service (QoS).

Patent CA-2264890-A1 (CA)
Inventor: SEARS JAMES B JR
IPC: B22D11/059
Filed: 1997-08-22
Abstract: A method of preparing a mold surface for a continuous casting machine includes steps of machining the mold surface to a substantially smooth surface, and work hardening the machine surface substantially throughout to impart a compressive stress to the surface. In the preferred embodiment, this work hardening is performed by applying a controlled shot peening process to the mold surface. The surface may then be buffed to a smooth finish, or coated with a material such as nickel or chromium. The residual compressive stress that is created by the work hardening stops cracks from forming or spreading in the moldface wall. This increases the life of the moldface, and makes the casting machine safer and more efficient to operate.

Abstract: The apparatus includes a flow control conduit (2) connectable with an output portion of the heart, prefer-ably a bypassed portion of the aorta, and includes a means of feeding heart fluid (R/O), for example blood or cardioplegia into the heart. The flow control device (1) includes in communication a variable resistance pressure control means (4) which is variably biased to a closed position to maintain on the bypassed heart region a pre-determined level of pressure, to facilitate the creation of back pressure during filling of the bypassed heart re-gion or a beat or pumping phase of the heart, and when the heart fluid pressure increases to reach a predeter-mined threshold, the pressure control means facilitates a release of fluid from the conduit, thus facilitating expul-sion of potential emboli from the bypassed heart region, and enabling "cycling" of the heart whilst in a bypassed condition, prior to the bypassed region being taken off bypass. The invention includes preferred and alterna-tive embodiments of variable resistance pressure control means including a hollow deformable bladder (16) bi-ased by a compressible control fluid externally of said bladder.
