Patent CA-2213599-A1 (CA)
Inventor: ALWARID ALI
IPC: F16H21/14
Filed: 1997-10-14
Abstract: The new invention is a novel development of the transmission of the motion between disks by means of a lever, and to change the force to torque, so that the rounds per minute (rpm) remain as they are. The increased torque will be multiplied by the ratio of the lengths of the lever from the pivot point to each one of the disks. The increase in the torque with the same rpm will reduce fuel requirements thus saving expense and avoiding excess pollution. It will also be possible to use the excess energy in various fields by transforming its form, which means we have perpetual motion.

Title: Oxygen activatable formulations for disinfection or sterilization
Inventor: ALLEN ROBERT C
IPC: A01N63/00
Filed: 1996-05-09
Abstract: Methods and composition are disclosed for producing air-activated, i.e., oxygen activated, disinfectant-sterilent solutions. Solutions containing a haloperoxidase (i.e., a halide: hydrogen peroxide oxidoreductase, such as myeloperoxidase, eosinophil peroxidase or lactoperoxidase) plus a halide or combination of halides (i.e., chloride, bromide and/or iodide), an oxidase (i.e., a substrate: oxygen oxidoreductase) capable of generating hydrogen peroxide, and a substrate specific for that oxidase, are separately prepared under aerobic conditions, but all of the component solutions are made anaerobic prior to final combination and mixing. The anaerobic formulations are dispensed into containers capable of maintaining the anaerobic condition (e.g., pressurized canisters). Dispensing the solution at the time of use exposes the formulation to air (i.e., oxygen) which activates its disinfectant-sterilent properties.

Patent CA-2227729-A1 (CA)
Title: Method and system for delivery of email and alerting messages
Inventor: HENDERSON DONNIE
IPC: H04M11/00
Filed: 1998-01-22
Abstract: A messaging system uses the standard email subject line to control where a message gets delivered, when a message gets delivered and the appearance of a message when it gets delivered. This enables a company to use its standard intranet email system as a pseudo real-time messaging transport with a range of delivery options. Several codes control the features of the alerting message, and a predefined escape sequence for use by the sender is recognizable by a dedicated server. This escape sequence enables these codes. By placing the escape sequence in a predetermined location in each message, the sender indicates to the system that codes for controlling the features of the alerting message follow the escape sequence. Using these codes, the user can then specify when, how often and in what manner the alert message is displayed to the recipient in a window on the recipient's workstation. In addition, the sender can certain aspects of message routing and delivery using these codes. In addition, routing of the message within the network can be controlled by the sender in the same manner by specifying a particular routing within the subject line of the message following the escape sequence. This includes routing the message to a facsimile, a pager or a telephone, or voice mail system. This is in addition to the normal email address used in the message.

Abstract: A method for high speed spin winding a coil on a continuous lamination core. A two piece or hinged bobbin (26) having two flanges (30, 34) is placed around a leg of the transformer core (22) and snapped together. Both flanges include an outwardly facing surface which defines a concentric groove (46). One flange includes passages (54) for receiving printed circuit board terminating pins (58) which are installed prior to winding the coil. The other flange has a circumferential gear (30) located in its outwardly facing surface.      The core with bobbin and terminating pins installed is placed into a spin winding fixture. A bobbin bearing (62) having a bearing surface including a circumferential ridge (74) is placed adjacent the outwardly facing surfaces of the two flanges (30, 34) such that the circumferential ridges (74) are partially received within the concentric grooves (46) of the outwardly facing surfaces of the two flanges (30, 34). A wire feeder terminates the leading end of the coil wire on one of the terminating pins (58). A drive gear engages the circumferential gear (30) on the flange and rotates the bobbin at high speed drawing wire from the wire feeder. The wire feeder moves back and forth between the two flanges to uniformly wind the coil wire on the bobbin. The wire feeder terminates the trailing end of the coil wire on the other terminating pin and then cuts the wire off. The terminating pins are pressed further into the flange until the desired length for printed circuit board connection extends outwardly from the opposite side of the flange.

Abstract: The characteristic of nonlinear processing with respect to image data is designated by a GUI and the result of the processing quickly displayed.    A personal computer 72 displays a GUI image for input on a monitor. When a user designates a nonlinear characteristic on the GUI image by an input device 70, the personal computer 72 extracts a break point approximation function indicating the nonlinear characteristic and displays the same in the GUI image. Further, the personal computer 72 generates a program for executing nonlinear processing indicated by the extracted break point approximation function by a linear array type multiple parallel processor (DSP 80) and downloads the generated program to the DSP 80.

Title: Process and device for correcting dynamic misalignments in cutting machine tools
Inventor: OSTENDARP HEINRICH
IPC: B23Q15/18
Filed: 1997-02-18
Abstract: The aim of the process and associated device is a substantially more accurate correction of dynamic misalignments caused unavoidably by vibrations in the machine than is possible with known processes. In the process, the disturbances which directly determine the misalignments at the point of action between tool and workpiece are determined. A mathematical process model is generated from the disturbances and used to generate the non-statistical components of the disturbances. On the basis of the process model, a preliminary estimate is formulated of the future behaviour of the disturbance at the point of action and this is then used to correct the misalignment. The process can be used with machine tools to improve surface finish.

Abstract: A rotating blowout preventer and method is disclosed that includes a flexible bladder that defines a pressure chamber radially outwardly of the bladder for direct activation of the bladder to allow for gas tight sealing along the variable profile of drill pipe and the irregular shape of the kelly. The pressure chamber for activating the bladder is preferably defined within the rotating seal assembly. As well, the rotating seal assembly includes both the bladder and the bearings. A pressure drop element is included within the hydraulic flow line through the rotating seal assembly so that the upper seal and bearing have a significantly reduced pressure drop for increased lifetime operation. The rotating seal assembly is hydraulically secured within the rotating blow-out preventer housing, preferably by remote control, by means of a preferred single cylindrical latch piston that moves upwardly and downwardly substantially parallel to the well bore axis. The latch piston wedgeably moves latch dogs radially inwardly to effect latching. After the latch piston is moved from the latch position, the latch dogs move radially outwardly as the rotating seal assembly is lifted from the rotating blow-out preventer housing as by a rig cat line to thereby effect quick change out of the bearings and/or the bladder.
