Patent CA-2320595-A1 (CA)
Inventor: GRAHMBEEK TAMAR VANESSA
IPC: E01F9/50
Filed: 2000-09-26
Abstract: The invention relates to a concrete pavement tile, which produces a clearly recognizable sound when touched with a blind person's cane or a white stick. In practice, it appears useful to incorporate sound sources in guide paths for the blind. The invention has solved this problem by providing a pavement tile with an upper plate of metal, which is supported by the tile at its circumference. The plate can be provided with regularly distributed outwardly projecting tears, bumps or ledges. Below the plate there is a sound space which can be formed by pressing the plate, upwardly convex, whereas a hollow executed tile give the same effect.

Abstract: A mount for one or more constant force curl springs uses a mounting block secured within a sash shoe channel to support the underside of a lowermost curl spring with a superposed curl spring mounted to counterrotate against an outer convolution of the lowermost spring. Uncoiled free ends of the curl springs pass downward on opposite sides of the mounting block and connect to opposite sides of a sash shoe arranged below the mounting block.      This connection is made by laterally sliding the spring ends into slots molded in the sash shoe so that barbs struck and bent from the planes of the free ends of the springs are lodged in widened recesses of the slots to retain the spring ends against upward withdrawal from the spring slots.

Abstract: The invention relates to a method for the heat treatment of residues containing heavy metals, carried out in a multiple-hearth furnace which is divided into three zones, each of which comprises several stacked levels. Said method consists of the following steps: continuous feeding of the heavy-metal residues into the top level of the first zone of the multiple-hearth furnace, the residues being gradually transferred to the second zone and dried during the transfer; continuous feeding of reducing agents and desulfurizers into the top level of the second zone, whereby the reducing agents and desulfurizers are mixed with the dried residues and the mixture is heated to approximately 800 ~C, calcined during heating and gradually transferred to the third zone;  heating of the mixture to approximately 1000 ~C in the third zone, whereby the metals are reduced and the waste gases resulting in said third zone are drawn off and treated separately; and discharge of the mixture from the multiple-hearth furnace.

Title: High performance debugging in a message flow environment
Inventor: O'FARRELL WILLIAM G
IPC: G06F9/445
Filed: 2001-04-27
Abstract: A message flow environment permits a developer to define a debug session in which nodes in a defined message flow have a debug function. A debug controller is used to select nodes as breakpoints using data in shared memory accessible to the nodes in the defined message flow. Each node having a debug function will determine whether it is a breakpoint by accessing the shared memory. Where a node determines that it is a breakpoint, the node will communicate debug information to the debug controller. An independent daemon runs to permit a developer to define breakpoints from the set of debug nodes. The nodes having a debug function maintain a stack in the shared memory which is sent to the debug controller by each breakpoint node when reached by a message.
