Title: Drive chain tensioner
Inventor: MUTH JAMES C
IPC: F16H7/08
Filed: 1993-09-28
Abstract: An apparatus for tensioning a belt or cable, reeved about first and second pulleys or sprockets, both mounted for rotation on supports. The apparatus includes a base plate and a post mounted through a closely-sized aperture in the base plate. An arm is mounted to the post at a mounting point at one end of the arm, such that the arm is rotatable about the post with respect to the base plate. An idler sprocket is rotatably attached to the arm at a point spaced apart from the mounting point of the arm, near the opposite end, and positioned so as to be engageable with the belt or chain. Engaging pins are positioned on the arm at a point near the idler sprocket. The base plate has corresponding holes for engaging the engag-ing pins on the arm in a plurality of positions with respect to the base plate. The post is a shoulder bolt which is inserted into the aperture from one side of the base plate and is fastened to the arm on the opposite side of the base plate by a nut threaded onto the end of the shoulder bolt, capturing the arm be-tween the nut and the shoulder. A spring captured between the base plate and the head of the shoulder bolt biases the bolt to slide through the aperture in the base plate, so as to engage the pins in the holes.

Abstract: The process consists in taking a fabric piece (1) of a width (A) corresponding to that of the cleaning cloth to be obtained and subjecting it to successive intermittent transversal cuts (3) in the direction of the weft, spaced according to the length (D) of the cleaning cloth, which cuts prevent unravelling and help the user to detach each cleaning cloth individually from the rest of the piece (1), the cleaning cloth having longitudinal edges which may not be unravelled in the direction of the warp. If the piece of fabric is of a width (mA) which is a multiple of the envisaged width (A) of the cleaning cloths (2), longitudinal cuts (5) are made in the piece of fabric spaced apart from each other (A) in the direction of the warp, after which intermittent transversal cuts (3) are made.      The resulting cleaning cloth (2) consists in a rectangular portion of fabric whose four edges may not be unravelled.

Patent CA-2132350-A1 (CA)
Title: Layered Video Coder
Inventor: NILSSON MICHAEL E
IPC: G06T9/00
Filed: 1993-03-29
Abstract: A layered coder includes a lower resolution predictive encoder (102) and a higher resolution encoder (402) providing coded low and high resolution signals at lines (110) and (218) respectively. The prediction error of the lower resolution predictive encoder (102) is provided as a prediction error estimate to the higher resolution encoder (402), the prediction error estimate being subtracted from the prediction error generated in the higher resolution predictive encoder (402) by the subtractor (210). This difference from the subtractor (404) is coded by the coder (212) whose output is made available on the line (218). The prediction error estimate from the up sampler (130) is added to the output from the decoder (220) by an adder (406) in order to complete the predictive loop of the higher resolution predictive encoder (402). The prediction error estimate can also be subtracted from the prediction error of the higher resolution predictive encoder in the transform domain. The layered coder makes available both higher and lower resolution coded signals, with good coding efficiency as the coding information obtained from the lower resolution encoder (102) is used in the coding carried out by the higher resolution predictive encoder (402).
