Patent CA-2276868-C (CA)
Inventor: BLAIR JIM S
IPC: F04B13/00
Filed: 1999-06-30
Granted: 2001-02-13
Abstract: A reciprocating fluid driven motor apparatus is provided for operating within a pipeline system carrying fluid under pressure to harness some of the energy stored in the pressurized fluid and convert it into mechanical motion for performing other desired tasks. The apparatus includes a barrel having an inlet in fluid communication with an upstream portion of the pipeline and an outlet in fluid communication with a downstream portion of the pipeline, and a differential pressure regulator in a by-pass portion of the pipeline connecting the upstream and downstream portions to create a greater pressure in the upstream portion than the downstream portion. A piston slides reciprocally within the barrel in a fluid tight manner. The piston has an interior cavity for allowing fluid movement therethrough, and a cyclically operable closure member for opening and closing the fluid movement through the piston. The piston is moved upwardly within the barrel by the pressurized fluid beneath the piston to an upper limit of travel upon closing the closure member, and the piston is allowed to fall by force of gravity from the upper limit of travel to a lower limit of travel upon opening the closure member to allow the fluid beneath the piston to travel through the interior cavity and into the barrel's outlet for discharge into the downstream portion of the pipeline. A piston rod extends from the piston and slidably through the barrel for transferring movement of the piston to the exterior of the barrel to perform a desired task. The entire system is closed so that no fluid leaves the apparatus but merely continues to travel along the pipeline.

Abstract: A dowelling jig for preparing aligned bores in corresponding joint faces of two work pieces which are to be joined using dowels, includes a spacer plate having opposite flat sides against which the side faces of the work pieces are placed and held. First and second drill guide arms are removable secured by securing arrangements to the spacer plate and to extend away therefrom in opposite directions, each arm providing a flat surface against which a joint surface of one of the work pieces is to abut. At least one line of through-bores are provided in each of the drill guide arms for guiding a drill bit at right angles into the work piece. The thickness of each guide arm is such that each through-bore has an axial length sufficient for guiding a hand held drill to drill a work piece bore substantially at right angles to the joint surface. The line extending along the guide arm parallel to an edge which abuts the spacer plate and the line of through bores on one arm corresponding in position to a through-bores on the other arm is such that the bores align when the joint faces of the work piece are brought into abutment.

Abstract: An interleaving method and apparatus is disclosed for an in-band on-channel (IBOC) digital audio broadcasting (DAB) system. The disclosed interleaver method and apparatus utilize a convolutional interleaver having a row size equal to one OFDM symbol and a time span of arbitrary size. A structured memory block is utilized in the de-interleaver at the receiver having a row size of one OFDM symbol (the number of active sub-carriers in the applicable sub-band of the IBOC system). The self-synchronizing nature of the present invention permits a receiver in an OFDM-based IBOC system to sort the scrambled blocks and descramble the received symbols according to its own frame count, without regard to the frame count of the transmitter.    The disclosed interleaver method and apparatus does not require interleaver synchronization between the transmitter and receiver. In one implementation, separate convolutional encoders and convolutional interleavers are applied to each sub-band in a multi-stream structure to provide independent error spreading for each sub-band.
