Abstract: A chain device including a sprocket wheel, a buffer ring provided on one side of the sprocket wheel for rotation relative thereto, and a chain meshing therewith. The buffer ring has an outer diameter greater than the inner-diameter dimension of a semicircular-shaped portion of the chain which is in meshing engagement with the sprocket wheel. Thus, when the chain and sprocket wheel are in meshing engagement with each other, the buffer ring is restrained and forced by the inner-diameter part of the semicircular-shaped portion of the chain, so that the ring is deformed into an elliptical shape. Each of the link plates which form the chain includes a depressed portion having a curved shape coinciding, in its radius of curvature, to the maximum radius of curvature of the elliptically-deformed buffer ring. Such curved shape of the depressed portion of the link plate contributes to the improvement of durability of the buffer ring, as well as to reduction of chain noise.

Abstract: A hydraulic shock absorber including inner and outer tubes telescopically fitted together and an orifice variable in response to relative movement of the inner and outer tubes. A large diameter tubular holder is disposed coaxially around an upper portion of the outer tube to provide a space between the outer tube and the holder, the space being divided by a tubular partition membrane disposed coaxially in the space into a high-pressure gas chamber located outside of the membrane and a low-pressure gas chamber located inside of the membrane and communicating with an upper space within the outer tube. The shock absorber is of the hydraulically and pneumatically operated type, is simple in structure, and can be assembled with ease while maintaining a desired degree of performance.

Abstract: An instrument panel device for automobiles, particularly cars, wherein the space on the rear side of the instrument panel is employed to provide air conduits for feeding conditioned air to the interior of the automobile. A closing plate is employed to close the space on the rear side of the instrument panel, and the closed space is vertically sectioned with a partition plate to provide two systems of air conduit passages which are insulated from each other. The respective air conduit passages communicate with blowing ports provided on the front surface of the instrument panel, with defroster blowing ports, and with side defogger blowing ports.

Abstract: A toy including a powered running toy member and a track along which the toy member runs, the toy member being made to run by rotation of the driving wheels of the toy member. The running toy member is provided with a switching arm which is attached to the lower side thereof and is adapted to trigger an operation for changing the running direction, and a mechanism for effecting the change of running direction when actuated by the swinging arm. On at least one end of the track, a mechanism is provided for causing swinging movement of the switching arm to automatically change the running direction of the toy member as the toy member reaches that end of the track. The running toy member has the form of an animal such as, for example, a bird, and incorporates various mechanisms for effecting various actions simulating those of the actual animal, e.g., turning of the head, opening of a beak, etc., by making use of power provided by the driving wheels.

Abstract: An apparatus for measuring and dispensing a predetermined quantity of particulate material from a container. The apparatus includes a measuring and dispensing assembly permanently secured at least in part within a container, particularly a disposable container such as a box of dry laundry detergent. The measuring and dispensing assembly defines a chamber within the container which may be opened to permit a predetermined measured quantity of the contents of the container to enter thereinto, and then closed to separate the measured quantity from the remaining contents of the container. To permit dispensing of the measured quantity of particulate material from the closed chamber, the assembly further includes a movable member which may be moved to expose a discharge opening in the container which is adjacent the chamber.

Abstract: The steps of handling ice cans in an ice making plant, such as placing the ice cans in alignment within one or more ice tanks, transferring ice cans each containing formed ice block to a stripping-off area, and placing and separating of the cover lid relative to ice can units, are automatically performed by an overhead travelling crane.Particularly, several ice can units are placed in the ice tank such that pairs of lugs provided on each ice can unit are arrayed in two straight lines to enable the overhead crane to selectively lift the ice cans.In order to produce high-quality ice blocks which are completely transparent through to the core portion thereof, each ice can is correlated with means for agitating ice making water contained therein and is connected with a piping for exchanging core water, in which impurities or foreign particles are likely to gather, with fresh water.The stripping-off of the ice blocks from the ice cans is also performed by an automatic system.

Abstract: The invention concerns an improved cylinder head.The cylinder head is fixed to the engine block by means of two short bolts 13 and 14 and four long bolts 15 to 18, all arranged at the points of a regular hexagon. The inlet and exhaust manifolds 20 and 21 are on the same side, on each side of the bolt 13, opposite to the rocker arm push-rods 9 and 10, and an injector carrier 34 placed obliquely above the bolt 14. The cooling liquid arrives under the inlet manifold 20, passes between the valves 5 and 6, and then directly cools the injector carrier 34.Application: reduction in the bulk of the upper part of the engine as regards width.

Abstract: A catheter formed of an elongated, hollow tube having a sealed, separate air passageway formed integrally of the tube and extending from a point near the forward end of the tube to an integral air inlet nozzle located near the rear end of the tube and extending outwardly therefrom. An inflatable barrel shaped cuff is mounted upon and encircles the tube near its forward end, there being an opening in the tube wall communicating the interior of the cuff with the air passageway for inflating and deflating the cuff. A cup shaped seal is also mounted upon the tube and is frictionally secured thereto by integral springy flanges which permit forwardly sliding the seal upon the tube but which resists rearward sliding of the seal.
