Title: Metering discharge bed for belt-driven roller conveyor
Inventor: BAKER TIMOTHY R
IPC: B65G47/34
Filed: 2005-12-06
Abstract: A metering discharge bed for a belt-driven roller conveyor is provided by a second section of rollers positioned downstream of a first section of rollers, the rollers being carried for rotation between opposed side frames. The rollers in the second section are of the same diameter as those in the first section and include two driven rollers that define the opposite ends of the second section. Each of the driven rollers has a drive roller associated therewith which is selectively engageable with the drive belt and has the same diameter as the rollers in the first and second section. Each of the drive rollers has a collar of a diameter greater than that of the rollers in the first and second section, and is linked to its driven roller by at least one belt trained about the driven roller and the collar. Consequently, when the drive rollers of the second section are engaged by the drive belt, the driven rollers in the second section are driven at a rotational speed greater than the rollers in the first section that is proportional to a ratio of the diameter of the collar to the diameter of the rollers.

Patent CA-2533655-A1 (CA)
Inventor: KUREK STEPHEN R
IPC: H01H21/02
Filed: 2004-07-23
Abstract: There is disclosed a paddle switch operated by pushing on the lower portion of a rocker paddle to turn the switch "on" or "off'. The lower edge of the paddle pivots in and out about its upper edge. The switch includes flexible driver means coupled to be driven by the rocker paddle. When the rocker paddle is pushed in, it urges the flexible driver means to rotate a cam means (366) in a first, clock wise direction, or a second, counter clock wise direction.  Alternate rotation of the cam drives a slider member (320) having a cam follwer (370) back and forth along a axis. A shaped leaf spring (352) cooperates with the cam follwer to assist in the movement of the slider and determines its rest positions. An indicator such as an LED (112) is used to indicate the state of conduction of the switch. When the rocker paddle is released, it is biased by a spring to pivot back to its initial position. The rocker paddle of the switch is not located within the frame and has a surface along its vertical axis of positive first differential and zero second differential, comprised of a combination of splines which extend between points of varying distances from a datum plane. This surface has zero second differential when the rate of height increase of individual splines is constant.

Abstract: A method and apparatus for operating a dryer used to reduce the moisture content of sheet material such as a jet veneer dryer. A drying chamber is provided and includes a plurality of individual, juxtaposed drying sections. Each drying section circulates air in a path substantially transverse to the path of movement through the dryer. A  single point exhaust system extracts the exhaust from the first drying section. A wet seal section located at the input end of the dryer includes an exhaust passage through which a gas sample is drawn by a sampling fan. Gases within the wet seal section are a combination of ambient air drawn through restricted passages at the entry to the wet seal section and exhaust gas that bleeds into the wet seal section from the drying chamber. A controller monitors the temperature of the sampled gases and ambient air and adjusts the rate of exhaust flow from the main exhaust system as a function of the temperature differential. A heating system is also provided for heating exhaust gases above a normal pitch condensation temperature.
