Patent CA-2357622-C (CA)
Title: Concrete recovery system
Inventor: BECKHAM DAVID JAMES
IPC: C04B22/00
Filed: 2001-09-24
Granted: 2003-12-16
Abstract: A method for recovering usable material from waste concrete is herein described. Specifically, waste concrete is mixed with water containing hydration stabilization admixtures, forming an aggregate slurry. The aggregates are then removed from the slurry for recycling. The slurry itself is then used for mixing with additional waste concrete, during which time the density of the slurry is monitored and action taken to ensure that the density of the slurry remains within acceptable parameters. The slurry is then used in place of fresh water when preparing subsequent batches of concrete.

Abstract: In a sealant-containing tire, an outer liner is fastened to an inner surface of a tread of a tire body, and a sealant chamber that is filled with sealant is defined between the outer liner and the inner liner, with an air chamber filled with air also being defined within the inner liner. By making the inner liner of flexible rubber of a 300%  modulus of 60kgf/cm2 or less, not only is a puncture in the inner liner caused by a nail made smaller, but the puncture is rapidly made smaller after withdrawal of the nail so that the flowing out of air from the air chamber is delayed. The flexible inner liner can easily be deformed by the air pressure within the air chamber and the sealant within the sealant chamber is therefore rapidly pushed into a puncture of the tread by the air pressure, thereby effectively repairing the puncture.

Title: Computer-implemented method and apparatus for matching paint
Inventor: LEWIS MARK DAVID
IPC: C09D7/80
Filed: 2000-12-15
Granted: 2006-04-04
Abstract: A computer implemented method for matching paint on a vehicle, having the steps of receiving in a central computer, from a remote terminal, vehicle identifying information relating to a specific vehicle and a first set of paint color data from a portion of the body of the vehicle. The central computer includes a database with vehicle identifying information for a plurality of vehicles, associated with paint color data and their paint formulations. A first process determines a first best match paint formulation which relates submitted vehicle identifying information and submitted paint data to a paint formulation. The latter is transmitted to the remote terminal. The central computer receives a second set of paint color data from the remote terminal representing a surface of the specific vehicle painted with the first best paint formulation and compares by a second process the second paint color data to the first paint color data so as to establish accuracy data. The accuracy data is applied to the first process so as to be implemented in subsequent paint formulation identifications.

Abstract: A quilting machine (10, 100, 200, 300, 400, 500) is provided with a printing station (20, 125, 225, 325, 425, 525) and a quilting station (44, 127, 227, 327, 427, 527). The printing station is located either in line and preferably upstream of the quilting station, with a conveyor (520) extending through each of the stations to convey a web of quilting material through the machine, or is off of the quilting line such that the material with a pre-applied pattern thereon is transferred, preferably in web form, to the line of the second station for the application of a pattern in registration with the first applied pattern. At the quilting station, registration longitudinal and transverse registration is measured and skewing or rotation of the material is determined. Opposite transverse sides of the material are differently adjusted to orient and register the material.  A master batch controller (90, 135, 235, 335, 435, 535) assures that the proper combinations of printed and quilted patterns are combined to allow small quantities of different quilted prod-ucts to be produced automatically along a material web. Ticking is preprinted with a plurality of different patterns, organized and communicated by the computer so that a print head can scan the material and print different patterns of different panels (32) across the width of a web. Identifying data (40) for matching the panels of a mattress product can be provided in data files printed on the fabric. Cutting and slitting of the panels from each other and the quilting and combining of the panels for assembly of a mattress product can be carried out manually or automatically using the data.

Abstract: A device is disclosed that enables a physician to remotely perform a physical examination of a patient. The device includes a hand control unit (100) that is shaped to accommodate a physician's hand, and includes a number of sensory modulation subunits (140) that can simultaneously detect applied pressure and exert pressure back to the physician. The hand control unit (100) connects through a computer (160) to a remote patient examination module (200) interfaces with a remotely located patient, preferably by wrapping around the portion of the patient's body that is to be examined. The patient examination module (200) includes a plurality of sensory modulation subunits (240) arranged in an array forming a flexible pad (202). In operation the sensory modulation subunits (240) of the patient examination module (200) receive a signal from the hand control unit (100) that indicates the location and magnitude of pressure's applied to the hand control unit (100) by the physician, and replicates that pressure in the patient through the sensory modulation subunits (240), which simultaneously detect the responsive pressures exerted by the corresponding portions of the patient's body. The magnitude and location of these responsive pressures are converted to a digital signal that is fed back to the hand control unit (100) sensory modulation subunits (140), providing the physician with a tactile response simulating direct contact with the patient.

Title: Pitch cycle search range setting apparatus and pitch cycle search apparatus
Inventor: SATO KAORU
IPC: G10L19/12
Filed: 2002-08-01
Granted: 2008-10-14
Abstract: An Adaptive Sound Source Vector Generator (ASSVG) 103 sets preceding and succeeding pitch cycles centered on an integral-accuracy pitch cycle T0 selected in the previous subframe as a range for searching for a fractional-accuracy pitch frequency, and extracts an adaptive sound source vector P(T-frac) that has fractional-accuracy pitch cycle T-frac within this range from an Adaptive Code Book (ACB) 102. A Last Sub Frame Integral Pitch Cycle Storage (LSFIPCS) 108 stores integral component T0 of the optimal pitch cycle selected by a Distortion Comparator (DC) 107, and when a pitch cycle of the next subframe is searched for, outputs this optimal pitch cycle integral component TO to the Adaptive Sound Source Vector Generator (ASSVG) 103. An Optimal Pitch Cycle Accuracy Judge Section (OPCAJS) 109 judges whether the optimal pitch cycle is of integral accuracy or fractional accuracy. A Comparison Judge Section (CJS) 110 restricts the number of times fractional-accuracy pitch information is selected in an optimal pitch cycle.

Title: Pipe coupling
Inventor: PUCKETT GEOFFREY BRYAN
IPC: F16L19/06
Filed: 2002-04-19
Granted: 2007-06-19
Abstract: A coupling assembly (10) for plastic pipes (12) including a nut (14), a body (20), a grip-ring (16) and a seal (18). The nut (14) can engage the body (20) through appropriate threads (28) and includes a hooked projection (36) having a sloping surface (46) adapted to abut against and provide a force on a corresponding surface (48) of the grip ring (16) within the body (20). A pipe (12) is inserted through the nut (14), grip-ring (16) and seal (18) into the body (20). Tightening of the nut (14) causes its sloped surface (46) to engage and the grip ring (16) to be forced both radially and longitudinally. Radial compression results in the grip-ring (16) engaging the pipe (12) whilst longitudinal force causes it to be forced into the body (20) simultaneously abutting against and compressing the seal (18) whilst dragging the pipe (12) further into the body (20). The nut (14) and the body (20) may further have tapered surfaces (46) that are brought together as the grip ring (14) is forced into the body (20). The physical connection between the body (20) and the nut (14) provides reinforcing for the nut (14), a feature especially useful when dealing with soft plastics. Further features include a lip (70) on the grip ring (16) that provides an additional support for the grip ring (16) when compressed as well as an abutment shoulder (56) on the nut (14) preventing the grip ring (16) from being pulled out of the body (20).
