Title: Engine with crankcase compression
Inventor: LYONS JAMES D
IPC: F02F7/00
Filed: 1999-09-22
Abstract: An engine (10) has a block with a crankcase chamber (22) and two cylinders (24, 26) extending radially from the chamber (22). A piston (56, 60) reciprocates in each cylinder (24, 26). The crankcase chamber (22) accommodates a crankshaft (64) which causes the pistons (56, 60) to move in diametrically opposite directions. At any time, both pistons (56, 60) are moving either towards top dead center or towards bottom dead center. An injector (88) is arranged to admit a fuel mixture into the crankcase chamber  (22) through an inlet opening (90) whenever the two pistons (56, 60) move towards top dead center. Two transfer tubes (98, 100) extend from an outlet opening (94) in the block to the combustion chambers of the respective cylinders (24, 26). The volume of fuel mixture drawn through the inlet openi ng (90) when the pistons (56, 60) move towards top dead center equals the sum o f the displacements of the pistons (56, 60). The greater part of this volume i s forced into a combustion chamber during an intake stroke with an accompanyin g precompression.

Patent CA-2345578-A1 (CA)
Title: Tool path measurement
Inventor: WANG CHARLES
IPC: G01B11/03
Filed: 1999-12-13
Abstract: The degree of accuracy a machine tool or the like is moved along a given path is determined by a unique preferably laser beam directing measuring system directing simultaneously or in sequence a laser beam parallel to the orthogonal axes of the two or three dimensional space in which the spindle or other object is to be moved in a path which can diverge appreciably in directions other than the directions of these axes. The beam directing means includes means which provides a measure of the actual positions the object has at various sampling times relative to the axis along which the beam is directed. This actual path position data is compared to the desired path position data used to program the object moving machine to determine the path position error at the sampling times involved.
Patent CA-2347155-A1 (CA)
Inventor: STUDER BEAT
IPC: B65H5/08
Filed: 2001-05-09
Abstract: For the horizontal positioning of serially supplied, flat objects (1) to be conveyed onward, the objects (1) are supplied suspended, one of their main surfaces (10) facing downstream and the other main surface (11) facing upstream. Prior to positioning, lower edge zones (13) of the objects (1) are selectively accelerated or retarded relative to the upper edge zones (12), so that the objects (1) are brought into a position inclined relative to the vertical. Thereupon the upper edge zones (12) are released and the objects (1) with the assistance of the force of gravity are positioned on an onward conveying means, selectively either the downstream or the upstream main surface (10 or 11) facing upwards.  For retarding. resp., accelerating the lower edge zones (13), for example, a conveyor belt or two conveyor belts adjoining one another is or are utilized, the speed (v.3) of the conveyor belts being adjustable for a conversion from accelerating operation to retarding operation. The principle advantage of the method and device described is the easy convertibility.  Method and device. for example, can be utilized for collating printed products or printed part products.

Title: Process for the recovery of sulphur from lead-acid battery scrap
Inventor: PRENGAMAN R DAVID
IPC: H01M10/06
Filed: 1999-12-20
Abstract: A process for recovery of substantially all the sulfur in a spent lead-acid battery as Na2SO4 is disclosed. The process comprises (a) breaking the batteries to remove the acid, (b) separating the plastic from the lead bearing materials, (c) smelting the lead bearing materials in a reverberatory furnace in an oxidizing atmosphere to volatilize most of the sulfur in the feed as SO2, (d) scrubbing the SO2 from the off gas stream using a soluble alkaline material such as NaOH, Na2CO3, or KOH to produce a soluble sulfite solution, (e) oxidizing the sulfite solution to sulfate, preferably by turbulent mixing of the solution with air, (f) adjusting the pH by adding the sulfuric acid separated from the batteries, (g) removing the contained heavy metals, (h) crystallizing the sulfate as Na2SO4 or K2SO4, (i) separating a bleed stream from the crystallizer and removing the contained chlorides as a mixed sulfate-chloride product by evaporation of the bleed stream in another crystallizer. The process produces a high grade Na2SO4 or K2SO4 product, condensed H2O for recycle to the scrubber, and a mixed sulfate-chloride product while reducing sulfur dioxide, chloride and heavy metal emissions to extremely low levels.

Title: Method and apparatus for automatic update of a printer driver configuration and status
Inventor: BODDEN EVRAL E
IPC: G06F9/445
Filed: 2001-07-31
Abstract: A method and apparatus for updating print drivers is described. The described system includes a port monitor that monitors the configuration and status of a printer. When changes occur to the configuration of a printer, the port monitor updates a print driver registry on the print server. The port monitor also wakes the print driver on the print server and informs the print driver of the configuration changes. Depending on the client operating system used, a client device connected to the server's shared print queue may either directly read or request the configuration data from the print server. In some client operating systems, the client device may also update a local registry on the client device to reflect the changes in configuration of the printer The described system allows print drivers to have a consistent interface to printer configuration and status data regardless of which version of the Microsoft Windows Operating System is used by the client.
