Abstract: In a double-acting hydraulic press: an outer press ram having a cylinder formed therewithin for the piston of an inner press ram, the inner and outer ram cylinders in communication with one another and the rams being subject to a common hydraulic actuating means, each ram carrying a separate and distinct tool at its forward face, and means controllably feeding pressurized hydraulic fluid to an intermediate section of said inner ram cylinder, whereby to control the effective hydraulic force applied to said inner ram and the tool thereof.

Abstract: The present case discloses a signal or flag assembly for use with a mailbox having a front door hinged at the lower portion thereof and comprising a body portion having sidewalls, said signal assembly comprising a flag or signal having a signal standard or support bent intermediate its ends to provide a signal carrying portion or arm and an attaching arm portion extending at an angle thereto, and pivot means for securing the attaching arm portion to one side of the mailbox. The attaching arm portion of the standard includes a pawl portion at its outer end for releasable latching connection with a signal latching member carried by said mailbox door.

Abstract: A power transmission for engines, motors, pumps and the like comprises a power shaft mounted to rotate about a fixed axis, an eccentric in the form of a tapered bar having arcuate ends secured on the power shaft to turn therewith, a power transmission ring having a circular internal bearing surface contacting the arcuate ends of the eccentric, a plurality of cranks connected to the power transmission ring by crankpins, each crank having a crankshaft journaled to turn about a fixed axis which is parallel to the power shaft. Power may be applied to any of the crankshafts by a motor coupled to the crankshaft or power may be applied to any crankpin by a pitman connecting the piston of an internal combustion engine or fluid motor to the crankpin. In either case, the power applied imparts non-rotary, planetary motion to the power transmission ring to turn the eccentric about the axis of the power shaft, thereby rotating the power shaft at the same speed at which each of the cranks is rotated but with more torque.

Abstract: A tool is disclosed for installing and releasing one-piece cable ties of the self-locking type which include an elongated strap having a series of pawl engaging detents thereon, and a head at one end thereof provided with an opening therethrough for receiving the other end of the strap and a pawl yieldably mounted in the head inclined partially across the opening for engagement with at least one of the detents on the strap when the other end of the strap is inserted through the opening. The tool comprises an elongated shank having a handle portion and a blade support portion forward of the handle portion, and a thin flat primary blade projecting outwardly from the blade support portion and insertable in the head of the cable tie between the strap and the pawl to release the pawl from engagement with detents on the strap so that the other end of the strap may be withdrawn from the head.

Abstract: A fuel vapor producing device comprising a liquid fuel or mixture bowl-shape container; an associated cover for said container having a fuel inlet valve; and a float secured in said device, said cover integrally incorporating therewith a cylindrical air filter housing disposed vertically and concentrically on top thereof; an air agitator duct integrated in said device extending from the air filter housing to the bottom thereto to agitate the fuel or mixture therein; another air duct in said air filter housing, said air duct extending to the inside of said container having an outwardly bent portion to produce a swirling effect of the air to achieve a higher degree of mixture; a multi air jet selector disc provided on said air filter housing, said selector disc having a plurality of spaced holes of gradually increasing apertures adapted to the air duct opening on said housing, the opening of said air ducts depending on the requirement of an engine piston displacement to control the air-fuel mixture of the engin

Abstract: In a hydraulic forging press having one or a plurality of press rams actuated reciprocatively through working oil by reciprocating motion of pump ram given by mechanical driving means, a closed forging press being provided with one or a plurality of punch rams disposed in a position to communize said working oil with said press ram and perform double action with said press ram, and actuated through said working oil by reciprocating motion of said pump ram.

Abstract: An adjustable flow rate nozzle for atomizing liquids comprises a tubular-like body for conducting a liquid under pressure having a discharge end terminating in a single plane surface, a structured device having a single plane surface which is attached with its plane surface contiguous with the plane surface of the tubular-like conduit and a slit-like aperature formed between the single plane surfaces of the tubular-like conduit and the structured device. The size of the slit-like aperture and thus the atomized flow rate is adjustable by securing structured devices to cooperate with the discharge end of the tubular-like body. The tubular body contains a main feed cavity of relatively large circular cross section and at least one corona cavity which is elongated outwardly from the main feed cavity. The corona cavity includes a pair of spaced sidewalls extending outwardly from the main feed cavity and an arcuate end wall joining the spaced side walls remote from the main feed cavity.

Abstract: Apparatus is provided for supporting the end portion of a workpiece blank which extends through and to the rear of power shear blades. The apparatus includes a table top and a frame supporting the table top. The front portion of the table top is supported for limited vertical displacement by rollers on opposite sides of the table engaged in horizontal track sections of vertically displaceable tracks interposed between the table top and the frame. The rear portion of the table top is separately supported by reciprocating rear table supports on opposite sides of the table top, the rear table supports being guided for vertical displacement in vertical ways provided on opposite sides of the frame. The table top is displaceable downwardly in response to downward movement of the movable shear blade, and is tiltable rearwardly after initial downward displacement by reason of the rear table supports being allowed greater downward displacement than the rollers supporting the front portion of the table top.

Abstract: This invention relates generally to water soluble wood treating compositions and methods for preservation of wood or products made from wood. In the general practice of this invention, wooden objects are treated with water soluble wood treating and preserving solutions consisting of blends of (A) from 0.1% to about 50% by weight of a chlorophenol selected from a group consisting of pentachlorophenol and tetrachlorophenol and mixtures thereof (B) from about 2% to about 98% by weight aliphatic alcohols selected from the group consisting of n-butyl alcohol, secondary butyl alcohol, isobutyl alcohol, tertiary butyl alcohol and isopropyl alcohol and mixtures thereof (C) from about 0.56% to about 45% of an amine selected from the group consisting of ammonium hydroxide, triethyl amine, trimethyl amine, methyl amine and methyldiethanolamine and mixtures thereof and (D) from about 1% to about 97% by weight water.

Abstract: A building panel comprising, when completed, a substantially rigid polyester resin building mass in sheet form having molded therein a plurality of closely compacted porous scoria rock particles of varied size in range of 1/4 to 11/4 inch diameter size and each comprising vesicules of varied size in range of 0.1 to 0.5 millimeters diameter that occupy the major portion of the volume of each such particle, such particles being compacted to form a substantially incompressible mass, said polyester resin being of substantial tensile strength and extending between the rock particles and including fingerlike intrusions extending into the larger vesicules of the rock particles and holding the rock particles together, said compacted rock particles substantially filling the entire volume of the polyester resinous mass, and including portions extending beyond the volume occupied by such polyester resin mass.
