Abstract: An air cleaner for an engine is provided according to the invention. Said air cleaner comprises openings for communicating with atmosphere provided along a peripheral portion surrounding a suction chamber communicating with a suction port of a carburetor, a filter to cover said openings, a suction path formed along the inside of said openings, a partition wall provided to separate said suction path and said suction chamber, and a communicating path to provide communication between said suction path and said suction chamber so that the suction sound of the engine is prevented by said partition wall from propagating directly to atmosphere and reduced due to interference caused when passing through the long suction path which is located inside the filter, without reducing the area of the path through which suction air passes.

Abstract: A circular coolant seal has a base flange arranged in a base plane perpendicular to the seal axis. A flexible resilient sealing flange is integrally joined at one edge to the base flange and terminates at its opposite edge in a sealing lip located in a sealing plane parallel to and spaced axially from the base plane. The sealing lip has a first portion extending from the base flange angularly away from the base plane and inwardly towards the seal axis to an intermediate hinge portion, and a second portion extending from the hinge portion away from the seal axis and angularly towards the sealing plane. The configuration, flexibility and resilience of the sealing flange is such that axial displacement of the sealing lip in relation to the base flange is accompanied by both axial and radial displacement of the hinge portion.

Abstract: A heat extractor system for a furnace, said furnace including a burner with a chimney that is connected but is normally not in operation. Instead, the furnace is connected to a vent in parallel with the chimney through a draft-inducing arrangement including a water spray in which water is heated and circulated to a point where the heat from the water is utilized. Due to the parallel arrangement of the vent and chimney, if the vent fails to operate, it will function in a fail-safe manner, with the combusted gases from the burner leaving through the chimney.

Abstract: A scraper-chain conveyor has channel sections or pans arranged end-to-end along which a scraper-chain assembly is circulated. Each pan is composed of side walls with a floor plate therebetween. Pockets are provided on the exterior of at least one of the side walls to accept and locate the heads of screw-threaded fixing components used to secure attachments to the side wall. The pockets take the form of shaped grooves each extending over substantially the entire height of the side wall. Each groove can receive a number of the heads, typically three, or fillers corresponding to these heads.

Abstract: Apparatus is disclosed for aligning and locating the nipples of an anode rod with the blind bores formed in one surface of an anode block. The apparatus includes a support table mounted for vertical movement on a stand. Alignment means are mounted on the stand above the support table. The alignment means is constituted by a plurality of alignment elements, each of which has the shape of a segment of a funnel. In use, the narrow ends of the alignment elements are introduced into respective bores in the anode block as the support table is moved upwardly. As the support table moves further upwards, carrying the alignment elements therewith, at least some of the nipples of the anode rod engage within the wider ends of the alignment elements, thereby directing the nipples into the bores in the anode block.

Abstract: An apparatus for detachably connecting a tool component to a frame component which is in turn adapted to be adjustably mounted on a vehicle. One of the components is provided with notched members for receiving engagement members on the other component. Contact members on one component are arranged to compressively engage resiliently compressible pads on the other component during entry of the engagement members into the notched members.

Abstract: A pressure release device for an internally pressurized fluid container has a dome-shaped inwardly concave closure element circumferentially joined to one end of the tubular container side wall. The closure element is deep drawn of tempered steel, with a circular central area spaced from an annular outer area by an annular intermediate area traversed by radially extending L/u/ ders Lines. A tab member is located in the central area. The tab member is partially circumscribed by a single weakened circular line of reduced material thickness, with the ends of the line being separated by a connecting area of substantially undisturbed material thickness and strength.

Abstract: A conveyor used to move and if necessary cool objects from a multiple sections in-line production machine, such as a thermoforming machine. The design is sectional, each section comprising a cooling station with high-low control of the cooling media and a push-out device used to transfer the objects from the cooling plate onto the moving conveyor belt. The pusher consists of an arm swinging around a stud, the latter also moving on a circular path, the correct sequence being obtained from a control box timed by the corresponding production machine section. The sections are secured together in the number corresponding to the number of sections of the production machine thus providing a suitable conveyor for a machine with any number of sections.

Abstract: A scraper-chain conveyor is composed in known manner of a series of channel sections or pans arranged end-to-end and interconnected to restrain relative longitudinal displacement. Cover members and spacers are detachably secured to the side walls of the pans with the aid of bolts anchored to the pans so as to define upper and lower guide passages for a chain. The connection between the pans includes projections at the ends of the pans and conveniently provided on inserts on spill plates attached to the pans, which projections extend laterally outwards from the pan side walls. Oval links or loops are inserted onto the projections and are retained by the spacers which extend partly across the projections and the links when assembled.
