Abstract: The conveyor system includes a guide mechanism defining longitudinally disposed sliding surfaces for guiding rib means secured to the conveyor belt for controlling vertical movement of the runs of the conveyor and in addition defines a slot for restricting lateral movement of the conveyor. This design provides accurate control of the positions of the conveyor, which thus serves to limit the space that must be provided for conveyor systems, particularly of those types that are quite long.

Abstract: In a fluid-flow pulsator, a housing has a chamber with an inlet and an outlet. Within the housing is a piston assembly having first and second pistons with the first having a working area less than that of the second. A valve associated with the assembly closes the outlet on movement of the assembly. The assembly is resiliently urged in a direction effecting closure of the outlet with the first and second pistons effectively being disposed in the chamber on opposite sides of the inlet. The introduced fluid pressure, the urging strength and the piston areas are correlated so as to produce pulses of fluid from the outlet in response to a supply of fluid to the inlet.

Abstract: An overexpanded thrust vector control nozzle has a converging extension section downstream of the jet exhaust stream deflecting section for defining a restriction or orifice. The orifice functions to elevate the exhaust pressure in the deflection section, which permits a reduction in nozzle size for operation at high and low altitudes. The orifice, which isolates the deflection section from outside ambient pressure, receives a deflected exhaust stream after it is turned in the direction opposite to that of the original stream deflection by the wall of the converging section. Control ports, which are adapted to communicate with a source of pressurized control fluid, are provided in the deflection section to position the exhaust stream.

Abstract: An arrangement in liquid sprayer containers designed to form an excess pressure inside the containers so as to allow the liquid contained therein to be discharged through a nozzle in the form of a spray. The arrangement inclues a head provided with a manually operable valve mechanism. The nozzle is in communication with the valve mechanism and arranged, upon opening of the valve, to discharge the liquid in atomized form. A cap encloses the head and when forced downwards it compresses the air in the space enclosed by the cap, whereby the valve opens a passage allowing the excess pressure to propagate into the container. Upon elimination of the excess pressure the valve mechanism again closes the passage.

Abstract: A conveyor apparatus is designed for the propulsion of metal sheets and more specifically sheets of ferromagnetic material. It operates by means of a linear induction motor associated with fluid cushion developing shoes. The apparatus is arranged to be movable perpendicularly to the sheets, its weight being counter-balanced so as not to react thereon. It is useful for sheet distributing machines.

Abstract: A vehicle turntable having a set of tracks and a drive tube are mounted for rotation about a vertical axis. A belt and pulley arrangement is provided for rotating the drive tube about its longitudinal axis in all rotative positions of the turntable while using rotation of an adjacent drive tube thereby eliminating the need for a separate independent motor on the turntable.

Abstract: A spray tip or button comprising a tip body, a break-up insert mounted in a recess provided in said body and communicating with a passage for admission of a fluid, and at least one intermediate member interposed in the recess between the passage and the insert, the intermediate member defining at least one metering orifice for the passage of the fluid into an expansion chamber between that chamber and at least one channel opening in a fluid collecting chamber of the insert.

Abstract: An apparatus for weighing and discharging material such as down, feathers, and the like is disclosed. Feathers, down and the like are transported from a storage container to a weighing drum by means of a flow of air which passes horizontally into and through the weighing drum, whereby the feathers are deposited in the drum. When a desired weight has accumulated, the flow of air to the drum is diverted and the accumulation of feathers may be discharged from the drum. Upon completion of the discharge, the flow of air carrying feathers is again directed into the drum.

Abstract: A plunger assembly for moving a batch of rod-like articles, principally from a conveyor into a tray, is provided with locating means, such as a flexible strip, which is movable with the plunger and which exerts light pressure on the top of a batch to control the articles as they are transferred.

Abstract: An apparatus for intermittently pushing a plurality of aligned carts along a predetermined path. The apparatus includes a pair of oscillating pusher bars having a plurality of aligned lugs thereon, which engage a portion of the undersurface of the carts and push them forward as the bars move in a forward direction. As the pusher bars move in the opposite direction, the lugs disengage from the cart, so as to permit the cart to remain stationary.

Abstract: Apparatus for simultaneously changing the orientation of articles and transporting the articles from a first location to a second location comprises a wheel, the first and second locations being adjacent the periphery of the wheel and being angularly displaced from each other relative to the periphery of the wheel, a plurality of recesses formed in the periphery of the wheel for receiving the articles, each of the recesses being of such size and shape relative to the articles as to retain each of the articles in a substantially fixed orientation relative to the recess in which the article is received, a kicker for feeding a respective one of the articles from the first location into a respective one of the recesses, a rachet for consecutively rotationally indexing the wheel thereby to bring consecutive recesses into substantial registry with the first location for receiving each of the articles fed from the first location by the kicker and a pair of rails for receiving the articles from the recesses at the se

Abstract: A device for raising and lowering a load while preventing swinging of the load comprising a container bridge having a displaceable trolley thereon, the trolley carrying a drum for hoisting cables which pass over sheaves to the load for raising and lowering the load by wind-up and pay-out of the cables. In order to prevent swinging of the load, a positioning wire extends from a drum on the trolley to the load at an oblique inclination which forms an angle with respect to the hoisting cables.

Abstract: An atomizer, particularly suitable for atomizing grease or lubricating compositions and useful in the foundry industry for lubricating molds, comprises a chamber in which is mounted a piston which is displaced from a rest position to an operative position by air under pressure against the effect of a spring operable to urge the piston to the rest position. Air under pressure is admitted to the chamber through an air inlet which is in constant communication with an outlet to the chamber by way of an air passage through the piston. An inlet for the composition to be atomized is controlled by a valve and opens to the chamber at a location at which it is closed when the piston is in the rest position and at which it communicates, in the operative piston position, with the air passage through a further passage provided in the piston so that the composition to be atomized is drawn by a Venturi effect into the air passage and entrained in the air flowing therethrough.

Abstract: This invention relates to a board grouping apparatus wherein boards successively discharged from a rotary cutter which cuts a web, for example, a corrugated board web and which continuously, transversely feeds the boards of a suitable length onto a conveyor to group the boards on the conveyor in any suitable predetermined number of sheets.
