Abstract: A thrust reverser for a fan jet engine. The engine has a primary nozzle for the rearward passage of primary gases and a fan associated therewith. An aerodynamically streamlined cowl surrounds the fan and is spaced from the primary nozzle. Space therebetween forming a fan nozzle for the passage of fan gases. The cowl has a fixed forward section and a translatable aft portion. Stowed the aft section abuts the forward section and forms a continuous inner and outer flow surface and when translated rearward to a deployed position an opening is formed between the sections. A pair of blocker doors are each rotatably connected to the forward cowl section through a pair of longitudinally translatable pivots. The pivots are normally biased in a forward position by a biasing spring. Links are pivotably attached between the blocker doors and the aft cowl section.

Abstract: An assembly for discharging ensilage from a silo, providing a substantially dust-tight path through which the ensilage may pass and also providing a discharge bag which need not be cut as the assembly is lowered within the silo. The assembly comprises an elongated, collapsible, ensilage discharge bag, a rigid, tubular pipe attached to the lower end of the bag, and funnel conduit means connecting a silo discharge window to the bag. The bag is collapsed or gathered around the tubular pipe when less than the entire length of the bag is needed, as for example, when the assembly is lowered alongside the silo to remove ensilage from its lower parts.

Abstract: Apparatus for wetting divided solid material so that it can be sucked into a storage tank by an entraining air stream without danger of damaging the expensive heavy duty air pump consists of a cylindrical body providing a wetting chamber which tapers outwardly from an inlet and inwardly to an outlet. A plurality of spray nozzles, each mounted in a recess, are provided uniformly spaced circumferentially and longitudinally around the chamber, so as to provide minimum spray pattern interference. A deflector means is provided immediately after the inlet to distribute the air flow over the chamber, consisting of a plurality of uniformly circumferentially distributed inwardly-extending finger-like members and an axial barrier on the flow axis. Another spray nozzle is provided spraying onto the deflector and also serving as a by-pass for the liquid supply pump, so that the nozzles operate with optimum spray patterns while the pump is at optimum flow capacity.

Abstract: A method and apparatus is disclosed for de-icing aircraft with hot water alone or with a mixture of hot water and a thixotropic de-icing fluid. The apparatus includes a centrifugal de-icing pump which is driven through a clutch only when de-icing fluid is being used thereby minimizing detrimental shear to the thixotropic fluid which shear causes fluid breakdown and reduction of viscosity. Several flow and pressure responsive controls are provided to control the engaging the disengaging of the clutch.The de-icing step may be followed by an anti-icing step if needed.

Abstract: The specification discloses an irrigation sprinkler of the impact arm type including a nozzle having a substantially cylindrical discharge passageway having four longitudinal grooves which are shallow and are V-shaped in transverse cross section. The grooves feather or turbulate the adjacent portions of the stream to cause, along with the action of the impact arm, very uniform application of water over the entire area of sprinkling.

Abstract: An emitter for use in irrigation systems of either the pressure compensating or variable flow type which emitter has an improved means of filtering and removing impurities so as to minimize the possibility of clogging. The emitter includes a first filter located inside of the fluid line or hose so as to eliminate most of the particles from ever entering the emitter. The emitter also includes structure so that once the fluid enters the emitter it is subjected to a cyclone path while going through multiple decompression chambers. This cyclone type turbulent path deposits the impurities against the outside walls of the decompression chambers where they accumulate in a collecting chamber for easy removal.

Abstract: A deflector spoon for a rotary impulse sprinkler includes upper and lower relatively sharply curved deflector faces separated by an intermediate, relatively gradually ramped deflector face. The three deflector faces are designed to react with a water stream from a sprinkler nozzle with the same driving force regardless of the specific water stream trajectory.

Abstract: A main landing gear assembly for an airplane includes a set of landing wheels journalled to a shock-absorber strut. The shock strut and wheels are swingably attached to the wing structure by a pair of trunnion bearings for lateral swinging movement between an extended position wherein the wheels depend downwardly from the wing for taxiing or landing of the airplane and a retracted position wherein the wheels and shock strut are swung inwardy and upwardly into a wheel bay in the airplane fuselage. The shock strut is braced in the extended position by a foldable drag strut and a foldable side strut, each strut attached at an intermediate position on the shock strut. The foldable struts and the trunnion bearings provide a four-point support configuration which allows a net reduction in aircraft weight due to improved distribution of drag and static loads into the wing/body structure.

Abstract: A solid, monolithic bicycle tire made of urethane rubber with a cured hardness of from 60 to 70 Durometer A. The tire is formed with a pair of laterally spaced bead shoulders that seat on the bead seats of the wheel rim, and is generally triangular in cross-section, with radially outwardly converging, slightly concave side walls that merge into a relatively narrow tread section. A circumferential, arch-shaped tunnel is formed in the inner side of the tire between the bead shoulders, and the material between the tunnel and the converging outer surfaces forms narrow, inwardly inclined side walls that are compressed when pressure is applied radially inwardly against the tread. The inclination of the side walls results in a substantial amplification of the deflection of the tire under impact loads, as compared to the deflection of similar-thickness side walls that are not inclined, but instead, are parallel to one another.

Abstract: The invention provides roller element bearings for roller conveyors. The bearings fit into the ends of hollow sleeve bodies to define the rollers of the conveyor. The bearings are designed to prevent the ingress of water through the bearings into the interior of the sleeve bodies, because collection of liquid in these bodies is unhygienic in food factory applications. The bearings are designed to act as water seals by the design of labyrinth seals between the inner and outer races of the bearings in that the labyrinth gaps are designed to allow outflow of liquid from the bearings, The clearances are not made so large as to allow excessive inflow of liquid into the bearing. The labyrinth seal therefore acts in two ways. It limits inflow of liquid into the bearing and also allows outflow of that liquid from the bearing to prevent accumulation of liquid in the bearing.

Abstract: A feed table for serially conveying sheets from the stack location magazine of an offset press to its printing head is pivotally mounted at its end adjacent the magazine. The other table end adjacent the printer head is mounted to the printer head housing by a spring-biased release mechanism that can be actuated by a release knob external of the housing to drop the table to a lower position to facilitate access to the interior of the printer head housing. Upward lifting of the printer head adjacent-end of the table by the press operator snaps the release mechanism into a retaining condition to hold the table at its normal raised position for the serial feeding of sheets from the magazine to the printer head. The release mechanism is carried by the feed table and engages with a pair of brackets mounted to the printer head housing.

Abstract: The invention provides a bearing assembly for a conveyor roller comprising a roller bearing comprising an inner race and an outer race. The outer race is for engagement in the end of a sleeve body while the inner race receives a stub axle. A blanking plate of the outer race seals off the interior of the sleeve body on a spring acts between the blanking plate and the stub axle so that the stub axle which serves to support the roller in a frame member can be deflected against the spring towards the blanking plate to enable the roller to be released from the frame member.

Abstract: A pocket atomizer that can be primed to hold liquid such as tear gas, in position for immediate discharge upon first application of its plunger. The atomizer includes a hollow piston having a hollow piston rod. The piston is movable up and down within a pump cylinder to force liquid up through the hollow piston rod. A check valve is located within the lower end of the hollow piston rod, and an orifice is located in the upper end of the hollow piston rod for discharging the pumped liquid. A capillary tube located within the hollow piston rod has an upper end coupled to the orifice for preventing liquid from draining therefrom between uses and thereby eliminates the necessity of priming the atomizer between uses. The lower end of the capillary tube terminates some distance above the check valve to define a chamber above the check valve. The check valve includes a valve seat and a ball of greater diameter than the capillary tube and of sufficient mass to seat in the valve seat when the piston is moved up.

Abstract: A device for installation in the water supply pipe to a bath shower head comprising a venturi aspirator connected to a vented measuring chamber, said chamber connected to a supply container for liquid additive. Restricting the vent to the measuring chamber creates a pressure differential causing additive liquid to flow into said chamber. With the vent reopened, the liquid additive flows by gravity and differential pressure into the duct connected to the venturi aspirator, mixing the air and water flowing to the shower head and producing an aerated shower spray with liquid additive dispersed therein.
