Patent CA-2112348-A1 (CA)
Title: Radial Ply Tire
Inventor: NGUYEN GIA V
IPC: B60C3/00
Filed: 1993-12-23
Abstract: An improved radial ply pneumatic tire 30 is described. The improved tire 30 has a first annular surface 23 located between the heel 22B and toe 22A of each bead 33,53,63 and a second surface 24 extending radially outwardly from the bead heel 22B. The first surface 23 is designed to be in contact with the bead seat 42 of the design rim 40 when the tire 30 is mounted and inflated to normal pressure. The first annular surface 23, when the tire 30 is unmounted, forms an average angle .beta. with the axis of the tire, when the beads 33,53,63 are axially spaced a distance D equal to the design rim width. The average angle .beta. is at least three degrees greater than the angle formed between the mating bead seat 42 of the design rim 40 and the axis of the tire. The second surface 24 is designed to be in contact with an annular flange 44 portion of the design rim 40 when the tire is mounted and inflated to normal pressure. The second surface 24A is inclined relative to a plane P perpendicular to the axis of rotation, at an angle .alpha. at least three degrees less than the angle formed between the rim flange 44 and the plane P.      Preferably the angle a is in the range of 3° to 20°) more preferably 3° to 15° while the angle .beta. is in the range of 8° to 25°, more preferably 8° to 20°.      The angular relationships relative to the design rim flange 44 permit the bead 33,53,63 and lower sidewall 21B of the tire 30 to rotate slightly upon mounting to the design rim 40, thereby improving the stiffness and handling characteristics of the tire 30.
Patent CA-2113966-A1 (CA)
Inventor: SCHMITZ HERIBERT
IPC: F24H9/06
Filed: 1994-01-21
Abstract: The invention is concerned with a gas hot water heater intended for installation in a wall and including a combustion chamber from which are guided heating gas tubings within a water-carrying housing. The housing is provided with connections for forward and rearward flow of water and an exhaust gas collecting chamber provided with connections for exhaust gas and condensate discharge. In the practice of the invention, a heating gas tubing passing from top to bottom through the water-carrying flat box-type housing is in the form of at least one pocket extending parallel to a broad rear wall of the housing. A water-cooled combustion chamber, disposed in an upper portion of the housing substantially corresponds, in plan view, to a flat rectangular cross-section of the housing. A burner insert opening of the combustion chamber is provided within or approximately within the plane of a front wall having a width corresponding to, and extending parallel with, a rear wall. This will result in an extremely flat design of the hot water heater involving low manufacturing efforts and permitting an automated manufacture.

Abstract: A mop wringer which includes a combination of a pail and lid wherein the lid can be locked to the pail. A first roller is mounted for rotation about a first axis in the lid while the lid includes an opening and a lid panel is hinged to the lid within the opening.      The hinged panel rotates about a hinged axis parallel to the first axis and a second roller is mounted to the hinged panel in an area of the hinged panel remote from the second hinged axis and where the second roller is adjacent the first roller and forms a nip therebetween. Spring means extend between the lid and the hinged panel to urge the hinged panel towards a closed position with the first and second rollers adjacent each other, but the hinged panel can be pressed downwardly to provide access through the opening for a mop. When it is required to wring the mop the hinged panel is forced to close the opening while the mop is within the pail such that as the mop is being pulled through the nip formed by the first and second roller the mop strands are wrung.
