A fuel pump and delivery system for gas turbine engines is disclosed having a plurality of interrelated pumping circuits to meet the engine fuel requirements over the entire range of engine operation. The system has three distinct but interrelated circuits for (1) start up and low-speed operating requirements, (2) normal operating requirements above engine idle speed, and (3) high altitude cruise requirements. A positive displacement gear pump functions in the low speed and start up circuit to p...

A fluid delivery system, such as a petrol pump, wherein there is a flexible hose between the pump and meter and the hosecock, has its main shut-off valve placed between the pump and the hose, a nonreturn pressure-relief valve near the hose end remote from the pump and shut-off valve, and a switch mechanism contained in the hosecock for operating the shut-off valve. Hence, whenever the flow is shut off only the back pressure of the nonreturn valve is felt within the hose, thus permitting the use ...

Method of and apparatus for delivering gobs of molten glass to glass forming apparatus at substantially identical rates of speed, such apparatus and method comprising a sloping trough having a gob contacting surface arranged to be cooled below freezing temperature of water, and supplying a coolant or cooling medium to said trough to form frost on said surface.

An air delivery system for particulate material wherein a vacuum is created in an area communicating an intake port with the flow of delivery air and a stream of pressurized air is directed into said area from a point adjacent the intake port to reduce turbulence caused by atmospheric air carrying entrained crop material into said intake port. The system also contemplates gradually expanding the cross-sectional area of the ducts throughout the delivery path to reduce damage to material entrained...

A fluid handling device especially suited for use in automatic chemical analysis which delivers measured amounts of selected fluids to intermittently advancing sample tubes at selected stopping stations and then, after selected intervals, withdraws predetermined amounts of the mixed fluids from said tubes for photometric analysis.

An air delivery system for the carburetor of the engine of a motor vehicle in which cold outside air is taken in through laterally spaced scoops on the vehicle hood and then directed laterally to the opposite sides of a hood mounted chamber sealingly receiving the carburetor air cleaner; a door is provided in each lateral air duct and these doors may be selectively moved by a control member in the passenger compartment between a "cold air" position in which the doors open the ducts to allow cold...

A delivery system for hot asphalt includes a plurality of semitrailers. Each trailer includes a V-shaped hopper having an asphalt supporting beam extending longitudinally through it. A tube extends around the hopper for use in spraying lubricating oil into the hopper prior to the loading of asphalt. Each trailer further includes a conveyor for unloading asphalt from the hopper into a paving machine. The conveyor is driven by a hydraulic motor that is controlled by a valve. The valve is mounted i...

In apparatus to supply an uninterrupted stream of paste, particularly for use in a continuous-rod cigarette-making machine, paste is normally delivered from a main container, but when the main container is empty, the paste supply is maintained from an auxiliary container. The main container is refilled while the auxiliary container is operating and when paste is again delivered from the main container, part of the paste goes to recharge the auxiliary container while further paste is simultaneous...

A thread storage and delivery device for conveying a thread from a spool to a working point on a textile machine. The device comprises a drum for receiving and storing a thread reserve. A disk is disposed substantially transverse to the axis of the shaft and is axially slideably mounted on the shaft. The disk has arm portions which extend radially through openings formed in the drum casing, said arms being axially supported on said thread reserve. The arm portions may be inclined upwardly relati...

An apparatus for setting up cartons, including a magazine that holds a horizontal stack of vertically oriented collapsed cartons. A receiving station accepts the cartons as they are fed thereto from the magazine by a moving conveyor lug and pushing bracket. Stationary vacuum cups and cooperative moving vacuum cups engage opposed panels of each carton and expand it to a rectangular open configuration laterally adjacent to the receiving station. A vertically moveable trough initially receives the ...
