The fibre or film can be used to apply a controlled quantity of a chemical to a desired location.
Patent CA-2138695-A1 (CA)
Inventor: IKEDA CHINATSU
IPC: H04L47/22
Filed: 1994-12-21
Abstract: In the congestion control method, when a queue length of a node in a virtual channel set up in an ATM network is a first threshold or more, a source terminal in the virtual channel is instructed to decrease a transmission rate. When the queue length of a node is a second threshold or more which is greater than the first threshold, there is halted the transmission of data cells from the preceding nodes or source terminals to the bottleneck node.      In a method of decreasing the transmission rate, congestion data is added to the header of a data cell passing through a node where the data cell queue is the first threshold or more, and the destination terminal which has received the data cell containing the congestion data transmits a rate decreasing control cell to the source terminal through the network. Receiving the rate decreasing control cell, the source terminal lowers the transmission rate. In another way, in a node where a cell queue length is the first threshold or more, a rate decreasing control cell is generated and transmitted to the source terminal.

Patent CA-2146801-A1 (CA)
Inventor: HASKELL BARIN G
IPC: H04N21/44
Filed: 1995-04-11
Abstract: The problems associated with slow timing recovery in an ATM receiver are overcome by detecting the transmission rate of a received bit stream and periodically detecting the transmitted Enc_CR values, which are used to calculate additional estimated clock reference (Est_CR) values between the actual transmitted Enc_CR values. The Est_CR values are then used along with the actually received Enc_CR values to generate a phase locked loop (PLL) error signal (TC_ERROR), wherein the PLL is caused to converge more rapidly. In one embodiment, the TC_ERROR values are generated for each received cell or packet instead of only for each received Enc_CR value and, consequently, timing recovery is significantly speeded up. Additionally, the Est_CR values can be adjusted to minimize the effects of lost cells, as well as, drift in the transmission rate.

Abstract: Apparatus for burning cut trees, stumps, brush and other waste wood on site includes a burn bin having an inner wall, an outer wall and an interior combustion region. To enhance combustion and limit the temperature of the outer wall, a flow of input air from a source of forced air is received and divided into a flow of combustion air which is directed to the combustion region, and a flow of cooling air which is directed to an air plenum between the inner and outer wall. To better accommodate thermal expansion and facilitate repair and maintenance, the inner wall may be slidably guided and loosely supported within the bin. Further, the inner wall may be segmented or formed from a plurality of sheet metal plates, each slidably guided and loosely supported within the bin. That part of the air flow system which extends away from the bin may have a knock-down construction to facilitate assembly, disassembly and transport, and the apparatus may include a skid adapted to carry the bin during use at work sites and during transport between work sites.

IPC: F04B43/12
Filed: 1994-03-17
Abstract: A peristaltic pump has a pump rotor (292) rotatable about an axis. The pump rotor carries a pump roller (300). An actuating rod (308) extends along the axis of rotation. The rod has a distal end and a proximal end. An actuator mechanism (310) is coupled to the proximal rod end for advancing the rod along the axis of rotation in a forward direction toward the pump rotor and in a rearward direction away from the pump rotor. A linkage mechanism (314, 322) is coupled to the distal rod end for converting advancement of the actuating rod along the axis of rotation in response to the actuator mechanism (310) into movement of the pump roller (300) radially of the axis of rotation between a retracted position free of contact with pump tubing and an extended position making operative contact with pump tubing (134, 136).

Title: Coin Mechanism with Magnetic Coin Discriminator
IPC: G07D5/08
Filed: 1995-08-23
Abstract: A coin mechanism for a bulk vendor or the like is provided with magnetic discriminating means, for selectively accepting coins having a magnetic component and rejecting coins or slugs which have no magnetic component. A magnet is lodged in the coin conveyor flush with the seating surface for a coin, and resilient urging means such as a spring projects above the seating surface. The attractive force of the magnet on a coin having a magnetic component is greater than the repelling force of the spring, so a coin having a magnetic component is retained in the coin carrier while a coin or slug having no magnetic component is unseated by the spring and ejected into a coin rejection chute.

Patent CA-2163475-A1 (CA)
Title: Hydraulic brake system
Inventor: DEBRECZENI JOSEPH
IPC: B62L3/02
Filed: 1995-11-22
Abstract: In general, a brake system for a bicycle or other small land vehicle includes brake pads for engaging the rim of a wheel, callipers carrying the brake pads, and a cable connecting the callipers to a brake lever.  When pressure is applied to the brake lever, the cable rotates the callipers to cause the brake pads to engage the rim.  Recently, hydraulic brake systems have come into existence.  Such hydraulic systems include a master or control cylinder actuated by the brake lever, and a slave cylinder connected to the master cylinder by a hydraulic fluid line.  The slave cylinder carries a piston, and the slave cylinder or piston is connected to the callipers for applying the brakes.  With repeated use, the lever becomes loose or develops play.  The solution to the problem provided by this invention incudes an adjustment screw in the slave cylinder for quickly and easily adjusting the position of the piston in the slave cylinder, so that in the rest position, the fluid pressure on the lever maintains the latter in a fixed position.  An eccentric cam can also be mounted on the lever for adjusting the rest position of the lever with respect to a piston in the master cylinder to achieve the same effect.  Another idiosyncrasy of hydraulic brakes is that the master cylinder contains a simple piston so that when the brake lever is actuated an unnecessarily high braking pressure is immediately applied to the brake pads, i.e. the brake pads are moved forcibly against the rim of the wheel.  In the present case, by using co-axial pistons in the master cylinder, a gentle force is initially applied to the callipers to move the Pads gently into position against the rim, and, with the pads in position against the rim, a higher force is applied to effect a braking action.

Patent CA-2169647-A1 (CA)
Inventor: LEWIS DAVID L
IPC: B23C5/26
Filed: 1995-01-17
Abstract: A toolholder (1) of the type including a collet (5) integrally formed with a shank (3) is provided with an interface between a locknut (7) and collet (13) which substantially reduces the torque required to turn the locknut (7) into a position which radially collapses the collet segments (17). In this interface, one of either the inner locknut surface (23) or the outer surfaces of the collet segments (17) includes an engaging portion (56) for wedgingly flexing the collet segments (17) inwardly when the locknut is turned, and a non-engaging portion (58) disposed between the engaging portion (56) and the shank mounted ends of the collet segments (17). The non-engaging portion (58) reduces the torque required to turn the locknut (7) by reducing the binding forces that would otherwise occur between the ends of the collet segments (17) and the inner locknut surface (23). To further reduce torque, the collet portion interconnecting the collet segments (17) with the shank (3) of the toolholder is rendered thinner by the provision of circumferential grooves (72, 76) that make the collet segments (17) more flexible. Sealing rings (66, 74, 81) are seated in grooves (68, 72, 76) present in the interior defined by the collet segments (17) in order to prevent errant flows of coolant or debris from collecting between the collet segments (17) and the tool shank (9) gripped thereby.
