Abstract: Flexible plastic bags used for the bulk storage and dispensing of fluids are often blocked from dispensing all the contents and/or entrap part of the contents in folds of the plastic as they shrink during dispensing. The invention is for a tongue or dip tube that is attached to the inner wall of the plastic bag near the location of the dispensing aperture. The tongue is formed of a laminate of two dissimilar materials, one non-hygroscopic and the other being hygroscopic, so that upon introduction of moisture into the bag, the hygroscopic layer will expand and the normally flat tongue will curl to form a thick tube that both prevents collapse of the bag and prevents closure of the dispensing aperture by the opposite wall of the bag.

Abstract: In making precision measurements with a television camera tube, the inherent scan non-linearity and magnification variations are readily calibrated by painting a grid of known dimensions on the tube face.

Abstract: Adjustments to the amount of valve lift in an engine are readily made by corresponding adjustments to the location at which a cam actuated push rod contacts the push rod side of the valve actuating rocker arm. The invention provides an accurate and rapid means for adjusting the push rod contact position by slotting the push rod side of the rocker arm and fitting a square adjustment plate against a fixed index on top and bottom surfaces of the push rod side. Each adjustment plate has a hole for accommodating a tappet bolt and the holes are off-center located so that there is a different space between the hole and each of the square plates' four edges that may be rotated to a position against the fixed index to provide any one of four separate rocker arm ratios and therefore amounts of valve lift.

Abstract: A variable speed ratio system for the controlled dispensing of a plurality of non-compressible fluids at high pressure, principally for use in reaction injection molding processes. Each of the pistons in two or more displacement cylinders that contain the fluids to be mixed is connected via a rack gear to the piston of a hydraulic driving cylinder, all hydraulic cylinders being connected to a common source of pressure. A variable speed change gear train connected to each rack gear will control the speed ratios of the displacement pistons irrespective of the fluid viscosities or mixing orifice sizes while the gears are subjected to only the differences in forces acting on the displacement piston rods.

Abstract: A fishing rod holder in which a rod is supported in a butt socket and a yoke on the end of a resilient strap attached at the other end to the top surface of a rectangular tubular housing formed of two channel members. A push switch in the housing and extending out to contact the inner surface of the resilient strap is closed whenever the yoke is moved inward by a fish strike of suitable magnitude, and an audible alarm or a lamp is selectively energized to indicate the fish strike. A novel sensitivity control in the system includes a threaded screw insertable in one of several threaded holes through the housing between the end of the housing and the point of attachment of the resilient strap so that adjustment of the screw on a desired position can accurately control the sensitivity of the alarm. Another feature is the inclusion of a remote alarm circuit that enables the angler to use the rod holder and alarm from a shelter or remote location.

Abstract: A two-piece dispenser for flexible plastic fluid-containing bags. An outer tubular sleeve has a flange attached to the sealed fluid-containing bag. The bore of the sleeve has two annular grooves, one adjacent the bag surface, the other with a semicircular cross-section and displaced within the bore from the first groove. The second piece is a coaxial barrel having sharp piercing points on a plurality of long, flexible blades, at least one of which carries a tooth extending radially from the surface for engaging the annular grooves. In the first or semicircular cross-sectioned groove, the tooth operates to strongly resist longitudinal movement of the barrel so that it cannot be accidentally removed or moved inward to pierce the bag. For dispensing, the barrel is forcibly pushed in to dislodge the tooth from the first groove, cause the blade tips to pierce the fluid-containing bag, and latch the tooth into the second groove to prevent any removal of the barrel from the sleeve.

Abstract: Dispensers for flexible sealed plastic bags used for the storage of wines or other liquids that may spoil when exposed to the air. The outer sleeve of each of the described embodiments of the dispenser is attached to the exterior surface of the sealed bag and either cuts or shears open the bag by a combination of rotational and longitudinal movement of the barrel of the dispenser within the sleeve. The fluid is thereafter dispensed through radial holes through the sleeve and the barrel by only rotational adjustment of the sleeve within the barrel.

Abstract: An improved safe bolt mechanism characterized by: slide bolts coupled to an inner surface of the safe's door by an elongated channel member; guide bars intespaced with the slide bolts and guided by the channel member for movement perpendicular to the slide bolts; elongated, bent cam rods journaled within apertures provided in the slide bolts and connected at their ends to successive guide bars; and a lockable bolt actuating mechanism for moving the guide bars within the channel member and thus extending or retracting the slide bolts due to the interaction of the cam rods and the slide bolts. Each of the slide bolts is individually locked by the cam rods to make forced entry into the safe more difficult. Optional locking pins attached to the guide bars can engage transverse bores provided in the slide bolts to lock the individual slide bolts even more securely.

Abstract: A manually operable mechanism for attachment to the adjustable stage of an inspection microscope for lifting a selected printed circuit wafer from its slot in a conventional disc holder and positioning it under the microscope lens for inspection. After inspection the mechanism is operated to lift the wafer from its inspection position, to transport it back into the disc holder, and carefully lower it into its correct slot. There is no manual handling of the wafers and therefore the normal losses resulting from breakage and contamination is eliminated.

Abstract: A small roller attached to a conventional power-driven paving roller or the like is hydraulically positionable to roll a surface outside of the normal rolling track of the power roller, such as against a building, high curbing, or the like.

Abstract: A remote control system for controlling the movement of manually operable mechanisms such as hydraulic control valves for hydraulically operating the various cylinders on equipment such as cranes, or the like. A remote control unit includes a deadman switch and one or more potentiometers that provide control signals to a corresponding number of servo circuits. Each servo circuit drives a motor and a motor position sensing potentiometer that generates an error signal back to the servo. The motor rotation provides linear movement to the hydraulic control valve through a solenoid operated mechanical coupling. The servo circuit includes safety circuitry that detects open or shorted circuits in the cable to the remote unit and releases the solenoid coupling and returns the motor to a neutral position.

Abstract: Self-closing fluid dispensing valves particularly for use with soft flexible fluid containers. The valves include a tubular outer housing having one end attached to the fluid container and an inner coaxial tubular barrel which may be rotated to align fluid dispensing holes in both housing and barrel. Tabs extending from both housing and barrel permit "two-finger" opening of the valves against spring forces that operate to automatically close the valves.
