Abstract: An internal combustion engine spark ignition system includes two inductors and a circuit for transferring energy from the inductors to a common spark circuit when current flow through the inductors is interrupted. Two transistors control current flow in the respective inductors and these are controlled by a control circuit which turns on and then off just one of the transistors when a normal spark is required, and which turns on both transistors and then turns these alternately on and off when an extended spark is required.

Abstract: This invention concerns finned tubes for use in heat exchanging whereby the fins have a generally T or Y shape. There is disclosed process and apparatus for making these Y and T-finned tubes whereby a smooth tube is subjected to conventional rolling process with the ends of the fins being subsequently notched into Y-fins and, if desired, subsequently flattened into T-fins. According to other embodiments of the invention the T-fins are constructed by an apparatus including an oblique surface which contacts the conventionally constructed fins causing the fins to be flattened into a general T shape.

Abstract: A nasogastric catheter comprises a tube of relatively flexible material defining a main duct extending from one end of the tube to the other end thereof, and first and second inflatable vessels which are mounted at the exterior of the tube and through which the tube extends. The vessels are situated along the tube approximately three-quarters of the way along the tube from the one end to the other end and are spaced from one another along the tube. First and second subsidiary conduits extend within the tube from the one end and communicate with the first and second vessels respectively but are isolated from said main duct. The tube is formed with at least one lateral perforation between the first and second vessels and a plurality of lateral perforations after the second vessel, the lateral perforations establishing communication between the main duct and the exterior of the tube.

Abstract: A device for closing off the space defined between an inner pipe and an outer shield tube comprises a sleeve of flexible resilient material having one end portion whose internal diameter is substantially equal to the external diameter of the inner end, a second end portion whose internal diameter is substantially equal to the external diameter of the shield tube, and an intermediate portion of substantially frusto-conical form joining the first and second end portions. The sleeve also has a tubular appendix which is joined to the intermediate portion of the sleeve and extends substantially parallel to the axis of the inner pipe and the shield tube for accomodating a signal transmitting cable. Angle plates are provided, with each having an axial portion extending over the extension of the shield tube at one end thereof and a radial portion extending at least part of the way from the axial portion across the clearance between the shield tube and the inner pipe.
