Patent CA-2255219-C (CA)
Inventor: MERINO LOPEZ JOSE
IPC: B29L30/00
Filed: 1998-12-15
Granted: 2008-09-09
Abstract: The mold employs an insert with two types of section, one forming a support, another keying with it. When positioned on a section of the tire mold, the support projects from it. When located for molding, each key is assembled in its support. The mold is closed and the tread is molded. The keys are then extracted from the support(s). Finally, mold sections are retracted to the open position to extract the support(s). Independent claims are included for: the tire tread, made as described; the mold used, and the mold insert (10). Each key (16, 17) part-delimits an opening (20-23) of the insert. Each can be moved in a direction other than that of mold (11) opening or closing. The arrangement allows removal of the insert from the mold, without damaging the molding produced. Other preferred features of the insert are detailed. Preferred features: In the method, each key to be freed from its support in the molding insert, is moved in a direction differing from that of opening/closing of the mold section carrying the insert.

Abstract: The present invention relates to a high-definition television system that comprises the following elements: at least two television cameras; a unit comprising several analog-digital converters; a video-signal-standard converter; a RAM-type memory; means for synthesizing an output video signal which are connected to each other and to the outputs of the television cameras; and a central processor such as a (personal) computer. The means for synthesizing an output video signal comprise a multiple-channel geometric distortion corrector as well as a synchronizing unit. The above-mentioned means are used in a dynamic process for efficiently assembling image fragments into a full "seam-less" image, wherein said image has a definition of at least 3000 x 4000 elements with a resolution and a contrast at least equal to those of pictures on large-scale photographic or cinematographic X-ray films. The corrector is connected to the television camera outputs through the analog-digital conversion unit and to the (personal) computer input through the video-signal-standard converter and the RAM. The control input of the synchronising unit is connected to the synchronisation output of at least the last television camera, while the control outputs of said unit are connected to the clock input of the analog-digital conversion unit, to the address inputs of the corrector and to the control and address synchronisation inputs of the video-signal-standard converter.

Title: Increasing causticizing efficiency of alkaline pulping liquor by borate addition
Inventor: MCBROOM ROBERT B
IPC: D21C3/02
Filed: 1999-05-31
Granted: 2008-07-08
Abstract: Method for improving causticizing efficiency in the conventional lime recausticization portion of alkaline pulping processes, such as are commonly used in the pulping and bleaching of wood and non-wood cellulose fiber materials. An aqueous solution of sodium carbonate is reacted with lime to produce sodium hydroxide (causticization) in the presence of borate to improve the causticization reaction efficiency.  Borate is provided in an amount sufficient to maintain a boron to sodium molar ratio in the range of between about 0.001:1 and 0.4:1, resulting in an increased causticization efficiency. An added benefit is reduction of inorganic deadload in the pulping circuit.

Abstract: A micromachined integrated opto-thermal sensor (10) having a rapid intensity varying or pulsing light source (14), an interference filter (16), shadow masking (113) or reflective blocking of light from therm al sensors (19), or differential operation, a gas cavity (20) into which the detected gas (21) can flow via a channel (114) or filter, and thermal detector elements to sense the heating of the gas caused by the absorption of light at a particular wavelength by the specific gas to be detected. Another version of the sensor is one with a dual cavity. One cavity (121) contains the gas to be detected and the other cavit y (122) is sealed from the ambient environment and contains no gas. Signals from the detectors from the cavities are subtracted from each other resulting in the elimination of a fixed signal (127) due to radiation impinging the detectors.

Abstract: A process for the on-site articulates imbrication between concrete slabs in which joints are formed, laying during the works, along the joint lines, a simple in mesh reinforcing device with a cutting and bending pattern already prepared in the workshops. In this ways advantage is taken from the shrinking phenomenon to obtain an alternative indentation along the joints of the adjacent slabs continuously in concrete, capable of satisfactorily producing a joint type link between them. The process is complemented with a concrete separating component facilitating crack formation and preventing the arrival of water to the platform and that may be fastened to the mentioned device. The invention is applicable to concrete paving on roads, motorways and port areas for the storage of goods, and allows road metalling to be designed without the need of bases and sub-bases.

Title: Portable self-energizing pressure sprayer
Inventor: LEER RICK L
IPC: B05B9/06
Filed: 2001-03-13
Granted: 2008-01-29
Abstract: A pressure sprayer is pressurized automatically with movement of the sprayer and maintains adequate pressure during non-movement to allow the ejection of an amount of liquid before needing re-pressurization. The pressure sprayer includes wheels that allow the pressure sprayer to be mobile. A cam is attached to the axle of the wheels which rotates with the rotation of the axle/wheels. A pressure pump is associated with the cam such that movement of the cam causes the pressure pump to pump liquid from a holding tank to an accumulator or directly to a spray wand in communication with the pump. The liquid may be sprayed (ejected) from the accumulator during both movement (pumping) and non-movement (no pumping) of the sprayer, while the liquid may be directly sprayed from the holding tank only during movement (pumping) thereof. Thus, as the wheels rotate due to moving the pressure sprayer, the cam causes movement of the pressure pump to fill the accumulator with the liquid under pressure. The pressure pump is adapted to obtain liquid from the holding tank and provide that liquid to the pressure accumulator. A relief valve is provided to relieve the buildup of pressure during movement of the wheels when no spraying is taking place.
