Patent CA-2287115-A1 (CA)
Title: Allograft bone fixation screw method and apparatus
Inventor: GERTZMAN ARTHUR A
IPC: A61F2/00
Filed: 1999-10-25
Abstract: A bone screw assembly constructed of allograft bone comprising a screw shank with a uniform diameter threaded portion, an unthreaded portion with a outwardly tapered end terminating in a drive head defining a wedge shaped configuration to form an undercut for the drive head. In operation a bore is drilled in the two bone sections, with one bone section being over drilled with the top portion of the over drilled bore having a tapered geometry which widens from the diameter of the bore. The bone screw is driven into the previously cut bore in the bone sections until the tapered surface of the bore engages the tapered undercut surface of the screw.
Patent CA-2291621-A1 (CA)
Inventor: KIRK GREGORY L
IPC: C12Q1/25
Filed: 1998-06-01
Abstract: A homogeneous high-throughput assay is described which screens compounds for enzyme inhibition, or receptor or other target binding. Inhibition (or binding) by the library compounds causes a change in the amount of an optically detectable label that is bound to suspendable cells or solid supports. The amounts of label bound to individual cells or solid supports are microscopically determined, and compared with the amount of label that is not bound to individual cells or solid supports. The degree of inhibition or binding is determined using this data. Confocal microscopy, and subsequent data analysis, allow the assay to be carried out without any separation step, and provide for high throughput screening of very small assay volumes using very small amounts of test compound.

Title: Procede et dispositif pour le sechage d'un gaz
Inventor: FORSTER RUEDIGER
IPC: C10L3/10
Filed: 1998-06-12
Abstract: Le gaz à sécher est envoyé dans un absorbeur (1) où il est amené en contact intime, à contre-courant, avec un glycol, le glycol absorbant l'humidité du gaz et les impuretés. Le glycol contaminé chargé d'eau est évacué de l'absorbeur (1) par une conduite (5). Il est ensuite régénéré dans un rebouilleur (9) dans lequel l'eau est éliminée par chauffage. Le glycol débarrassé de l'eau est envoyé dans un réservoir (10) d'où il peut être recyclé vers l'absorbeur (1). Le glycol prélevé du réservoir (10) est épuré en le mélangeant avec au moins sa moitié d'eau, le mélange est porté à une température supérieure au point de trouble et y est maintenu pendant une durée prédéterminée de manière à séparer les impuretés par floculation. Les impuretés floculées sont éliminées par filtration sur un filtre (18), et le glycol épuré mélangé à l'eau est renvoyé au rebouilleur (9) via une conduite (19). Le procédé de séchage est très économique, du fait qu'il permet d'intégrer une épuration coûteuse et compatible avec l'environnement du glycol.

Patent CA-2300611-A1 (CA)
Title: Sharpening apparatus
Inventor: NIESCHULZE HENRIK
IPC: A01F29/22
Filed: 2000-03-10
Abstract: A sharpening apparatus for sharpening the blades of a forage harvester chopper drum includes a carriage to which is mounted a grindstone holder that holds a grindstone that is moved across the chopper drum during sharpening operation. The grindstone holder includes an element which is mounted to the carriage for movement towards the chopper drum in order to advance the grindstone. The holder element contains a threaded bore in which is received a threaded shaft that has a ratchet wheel fixed to it. A  pawl is located in the path of movement of the ratchet wheel so as to be engaged thereby when the carriage reaches a reversal point at one side of the drum, this engagement causing the ratchet wheel to be rotated by an angular distance occupied by one tooth so that the threaded shaft causes the grindstone holder to move axially therealong and toward the chopper drum so as to advance the grindstone. In one embodiment the element of the holder is cylindrical and is received in a cylindrical opening in the carriage and fixed therein against rotation by a pair of feather keys. In a second embodiment, the element of the holster is a block, with the block and the carriage having cooperating surfaces which guide the movement of the holder towards the chopper drum while preventing any rotation of the holder about the axis of the threaded shaft.

Abstract: This patent is for water with specific characteristics. The unique characteristics make this water perfect for drinking and for medical applications.   In first case the features of water provide antibacterial effect. In this case is a property Exhibited by ions of silver (Ag++) provides clean water with antibacterial effect. This water can be use as plain drinking water or for preparing juices. For juice or any drink these properties have a special effect.   A juice or any drink (cola, sprite, etc.) or water with substances of Ag++  permits to preserve antibacterial action for a long period of time.   When used for dissolving drinks this water acts as a preservative extending shelf life to several years.        This water may be used for personal hygiene.   After several years of drinking such water human body accumulates the chemical substance. Ag++ ions have purifying and antibacterial effect.        The water with ions Ag++ has preventive anticancer effect.   This effect was used in Europe where Christian (Russian Orthodox) clergy used silver objects to preserve water with antibacterial qualities for one year.   Those who used to drink water with Ag++ didn't have cancer. This statistics was maintained for several centuries. In the cities where there was no such "holy"  water there were cases of cancer.     The water with ions of Ag++ may be produced by a number of methods. For example to activate the water with Ag++ it is possible use passive filter with Ag. When the water delivered by pipe activation by Ag will be processed inside the pipe.

Abstract: A unified messaging system is provided that includes two-way synchronization and replication of messages. The unified messaging system includes a workstation, a voice-mail server, and an e-mail server. The workstation may be a personal computer, for example. The workstation includes an agent to monitor messaging activities within the workstation mailbox. Also, the voice-mail server includes a proxy e-mail client (PEC) to operate and retrieve e-mail messages in the absence of the workstation. In accordance with the system and method of the invention, two-way synchronization and replication is provided. The two-way synchronization and replication operates between the workstation and the voice-mail server. Specifically, the replication operates between the e-mail store, e.g., the mailbox, of the workstation and the voice-mail store of the voice-mail server. The replication duplicates messages in each of the mailbox of the workstation and the voice-mail message store of the voice-mail server. Thus, the voice-mail message store contains both the voice-mail and the e-mail. Further, the e-mail message store contains both the e-mail and the voice-mail.
