Patent CA-2215169-A1 (CA)
Inventor: SCHWERT SIEGFRIED
IPC: F16L55/165
Filed: 1996-03-29
Abstract: The invention relates to a process for pulling a pipe (2) laid and/or to be laid in the ground to a trench below and accessible from ground level, in which there is a traction system in engagement with a traction component (3). The traction component is taken through the pipe and engaged with its rear end, viewed in the pulling direction. The traction component with the pipe is then drawn to the trench in steps by the traction system, with the traction device making a forward and a backward stroke at each step. During the backward stroke the traction component is kept under a tension corresponding to its elastic expansion during the forward stroke. In this way the traction component is kept permanently under tension throughout the pulling process, thus preventing the traction component from alternately expanding and contracting at each step. In a preferred device for implementing this process, the traction component has catches (4) with a predetermined spacing and the traction system has a pulling member (12) which engages with one of the catches during the forward stroke and a retainer (17) which is engaged with one of the catches during the backward stroke.

Patent CA-2217411-A1 (CA)
Title: Method for controlling the speed of a pump based on measurement of the fluid depth in a well
Inventor: HALISKY RONALD W
IPC: E21B47/04
Filed: 1997-10-06
Abstract: A method and apparatus for measuring the depth of fluid in a well and for controlling the speed of a pump which pumps fluid out of the well according to the measured depth is disclosed. The depth of fluid in a well is measured by sending an acoustic pulse into an annulus between the well casing and the production tubing and sensing reflections of the acoustic pulse from collars on the tubing and a reflection from the fluid surface. Since the collar spacing on the production tubing is known, the distance from the top of the well to the surface of the fluid can be obtained by accumulating the distance associated with the collars detected in the reflection signal. The collar reflections are sensed by converting the reflected acoustic wave into electrical signals and then amplitude demodulating the broadband electrical signals. Once the distance from the top of the well to the surface of the fluid is determined, the height of the fluid above the pump inlet can be obtained by subtracting the distance from the top of the well to the surface of the fluid from the known distance from the top of the well to the pump inlet. The speed of the pump, and therefore its pumping capacity, is controlled according to the height of the fluid above the pump inlet.

Patent CA-2221412-A1 (CA)
Title: Aeration type rotary drying machine
Inventor: YAMATO YUKIO
IPC: F26B11/02
Filed: 1996-04-08
Abstract: An aeration-type rotary dryer injects air into or onto a flow of materials a rotating cylinder. The air is supplied to an air duct (21) axially passing through the cylinder (10) from the outlet box (11) to the inlet box (12). The axial duct (21) is composed of a plurality of longitudinally, successively connected tubular members (22, 23, 24) each nearer to the inlet box being smaller in diameter than other. The most inlet-sided member (24), located in a central opening (32) of an inlet partition (31) of the cylinder, has the smallest diameter, so that the inlet partition has the central opening reduced and its threshold height increased. This results that the materials are prevented from returning to the inlet box out of the cylinder. The most outlet-sided member (22), located in a central opening (34) of an outlet partition (33) of the cylinder, has the largest diameter, so that a void space in the central opening (34) may be too small to exhaust air.      There is a remedy that air exhausts through the outlet partition (33) composed of a plurality of louvers (35) which are disposed at regular intervals on the inner periphery of the cylinder. This allows the dryer to double an amount of exhaust air as well as a drying capacity as compared with the conventional non-aeration type rotary dryer having the same size cylinder.
