Patent CA-2273653-A1 (CA)
Inventor: BAILEY WILLIAM K
IPC: B24D9/00
Filed: 1999-06-04
Abstract: A rotary abrasive wheel is provided having a central hub, at least one generally flat abrasive sheet carried by the hub for co-rotation with the hub and means retaining the sheet on the hub. The abrasive wheel preferably has a plurality of abrasive sheets each with an opening through which a shank portion of the hub is received with the ends of each sheet generally rotatably spaced or misaligned with the ends of each adjacent sheet to provide a generally circular perimeter of the abrasive wheel. In one embodiment, the hub preferably has an enlarged head at one end of a generally tubular shank which has internal threads constructed to receive a threaded portion of a mandrel which has its other end received in a chuck of a rotary machine to drive the wheel for rotation. Preferably, after mounting each abrasive sheet on the shank, the free end of the shank is cold-formed providing a plurality of generally radially outwardly extending tabs which retain and capture the abrasive sheets against the enlarged head of the hub. In another embodiment, the hub has an enlarged head at one end of a generally cylindrical shank which has an externally threaded portion and a mandrel portion extending from the threaded portion and constructed to be directly received within a chuck of a rotary machine which drives the wheel for rotation. In this embodiment, to secure the abrasive sheets, a nut may be received on the threaded portion of the shank to capture the abrasive sheets against the enlarged head of the hub. In either embodiment, the periphery of the wheel defined by the ends of each generally flat abrasive sheet is rotatably engaged with a workpiece to remove material from the workpiece.

Abstract: A vacuum trash collection vehicle has a debris container and a source of vacuum, both located on the vehicle. There is a hose connected at one end to the debris container and has the source of vacuum applied thereto. The other end of the hose is open to form a collection nozzle. There is a boom for supporting the nozzle during use as a debris collection device with the boom including a rear support arm pivotally mounted to the vehicle and supporting the hose in a rear area and a forward support arm pivotally mounted to the rear arm and supporting the hose at an area forward of the rear support arm. There is a control element accessible to the vehicle driver for moving the hose and nozzle. There is a spring pivotally connected between the rear and front support arms which urges the front support arm in an upward direction to, at least in part, carry the weight of the hose for assisting the vehicle driver in operating the control element. An adjustment means readily accessible to the driver allows him or her to vary the moment arm by which the spring urges the front arm upward, thereby varying the height at which the front arm supports the hose.

Patent CA-2286355-A1 (CA)
Title: Separator
Inventor: HEDREN MATTIAS
IPC: B03B5/36
Filed: 1998-04-06
Abstract: The invention relates to a device (1) for separating solid andlor semi-solid substances (3) located in a liquid (2), in which the device includes a container (10), a first sloping screw conveyor (20) and a second sloping screw conveyor (30). The first conveyor has a first portion (22) which forms a channel in the bottom of the container.      Bodies of a density exceeding that of the liquid are accumulated in the channel by sedimentation.      The first conveyor displaces the accumulated bodies up out of the liquid. The second conveyor (30) has a lower portion (32) located in the liquid (2), in which portion the path of the conveyor is provided with screen openings (42) for the passage of liquid during separation of solid and/or semisolid bodies (3) accompanying the liquid. The second conveyor (30) displaces the separated bodies from the lower portion of the conveyor, at the same time as the screen openings are cleaned. The screen openings discharge in a recepient (50) whose liquid level determines the liquid level in the container (10) and thereby determines the liquid flow through the screen openings.

Title: Multichannel amplification system using mask detection
Inventor: HA THOMAS
IPC: H03F1/32
Filed: 1999-10-18
Abstract: An apparatus and method reduce out-of-band frequency components of an amplified, multichannel RF signal able to have at least two frequency bandwidth limited signal channels, each channel having a respective carrier frequency which is not known in advance. The channels can, for example, be dedicated to CDMA signals. Each channel of the amplified RF signal has both in-band frequency components and out-of-band frequency components. The apparatus and method feature a network for amplifying an input signal for producing the amplified RF signal, the network having adjustable electrical characteristics, and a control system connected to the network for locating a frequency within the bandwidth of one of the channels of the amplified RF signal and for detecting energy in the out-of-band frequency components for the one located channel for producing control signals relating to the energy in that one channel. As a result of adjusting the electrical characteristics of the network, the energy in the out-of- band frequency components for that channel, and all other channels of interest, can be reduced.

Title: Carbon monoxide and smoke detection apparatus
Inventor: JOHNSTON DEREK SCOTT
IPC: G08B21/14
Filed: 1998-08-05
Abstract: A smoke sensor and a carbon monoxide sensor are integrated into a common detector housing (50a). The smoke sensor is coupled to the smoke detector integrated circuit (114) which generates a binary output signal indicative of the presence of smoke. This signal is coupled to a programmed microprocessor (102) in the detecting housing (50a). The carbon monoxide sensor is also coupled to the microprocessor (102). Outputs from the two sensors are processed substantially independently. In the presence of smoke, the smoke alarm is generated by the microprocessor. In the presence of sufficient levels of carbon monoxide, in the absence of smoke, a carbon monoxide alarm will be generated. The smoke alarm and the carbon monoxide alarm are distinct from one another.
Patent CA-2305123-A1 (CA)
Inventor: BATES CARY L
IPC: G06F40/189
Filed: 2000-04-12
Abstract: An apparatus and method improve the readability of text on a computer system by changing the positioning of one or more words to eliminate potential problems in readability that can be identified by examining the text. When a potential problem is identified, the word to word positioning of text may be adjusted to compress one or more lines and/or to expand one or more lines to move one or more words to a different line. For example, if two adjacent lines begin with the same word, the first line could be compressed so the first word of the second line is moved to the end of the first line. In the alternative, the first line could be expanded so the last word of the first line is moved to the first word of the second line. By selectively changing the positioning of words, the readability of the text may be greatly improved.
