Abstract: A valve is disclosed having a generally cylindrical body having an inlet and an outlet opening and a lateral opening. The valve body is received in a cylindrical collar which is heat shrunk onto the cylindrical body of the valve to provide a prestressed condition in the valve body thereby substantially increasing the strength of the body.

Abstract: A strip stacker for stacking in parallel planes, plate like strips of electronic components. The machine has a trap door onto which the plate like strips are placed in succession. Each time a strip is placed on the trap door its position is sensed by an electronic eye which actuates a motor to swing the trap door down allowing the strip to fall down a slide with its lower edge into a tray. A compacter bar is slideably supported in the tray and two locating pins project into the tray to hold the strips already stacked in position as the compacter bar retracts. Each time a strip falls from the trap door the compacter bar is retracted, the pins retract, and the compacter bar extends forcing the strip against the end until the fallen strip is in position behind the locating pins and pushing the tray down the slides. The locating pins extend holding the last strip against its predecessors. When the tray is full it will be at its lower extreme position and will be removed.

Abstract: A duct system is disclosed for increasing the efficiency of a vehicle by decreasing the air resistance of the vehicle.

Abstract: A device for holding two ketchup bottles in mouth to mouth relation to empty the ketchup from one to the other is disclosed. The holder is made of a flat sheet of flexible material such as cardboard or thin plastic with diamond shaped slots in it so that the sheet can be formed into an hour glass shaped configuration. One ketchup bottle can be inserted in one end of the configuration and the other can be inverted and inserted in the other end bringing the bottles into mouth to mouth relation with each other so that the remaining ketchup in one bottle can be emptied into the other bottle.

Abstract: A recycle water treatment system for separating oil vapor from steam recovering the oil and heat from the steam and destroys microorganisms and exotoxins which incorporates an inclined duct connected to a barometric condenser with a container for oil at the lower end of the condenser. Oil entrained in the steam is carried up the duct and over the barometric condenser. The steam heats the condenser water that is recovered while the entrained oil flows back down the duct into a recovery container. The condenser water-steam condensate mixture is maintained at about 180.degree. F. for a period of time sufficient to destroy microorganisms and exotoxins.

The arm has a cylinder attached to its lower end that engages the gage block to provide a positive precision locating device for the arm so that a sine bar is formed by the arm supported on the column.

Abstract: A control circuit and auxiliary power supply and a switching means for connecting the load selectively to the auxiliary power supply and the main power supply.The main power supply may be a public utility power line, and the auxiliary power supply is a windmill, a motor and generator all connected together on a common shaft. A control means senses the output voltage of the generator or output frequency and controls the switch to either connect the load to the power line or the auxiliary power supply.A battery is supplied for storing excess windmill power and for driving the motor and generator during periods of low wind.

Abstract: A utility knife guide made up of a body formed of sheet material bent to form a holder for the handle of the knife and a guide to control the path of cut of the blade parallel to a side edge of an object being cut.

Abstract: A balloon game having a target made up of two laterally spaced frame members held in spaced relation to each other, a balloon, and a paddle for each player. The frame members have an operative to permit the passage of the balloon and are spaced sufficiently to narrow the effective target area through which the balloon may pass. The balloon is a conventional type of inflated spherical child's balloon, blown to a size that allows it to float, and fall slowly. The paddles are of a conventional type presenting a flat area to impact the balloon and a handle area to be grasped by the player. The target has a knock-down construction for easy storage and quick assembly.

Abstract: A piston for use in spring-closed valves whose semi-toroidal shape minimizes the possibility of the piston jamming during tipping motions while providing maximum guidance, sealing area and maximum bearing material for resisting side wear.

Abstract: This application discloses a process of making electrically conductive fiber glass articles whereby carbon black is mixed with the resin to provide the desired value of electrical conductivity. A large amount of titanium dioxide is added to counteract the black color resulting from the carbon black addition. The resulting paste is added to fiber glass and the resin is cured thus resulting in a light gray or other gray tones. It is important that the carbon black, titanium and resin be thoroughly mixed to disperse the carbon and other pigments, and the mixing may be accomplished by means of a high intensity mixer or ball mill.

Abstract: An integrated circuit device is disclosed for sensing dew point which uses integrated circuit techniques supported on a suitable substrate. Four semi-conductor junctions are used which are a Peltier junction or a junction capable of emitting or absorbing heat, a light-emitting junction, a junction that generates electrical current when exposed to light and a temperature sensing junction. The circuit cooperates to control time and switch the current through the Peltier junction to heat and cool it. The light-emitting junction emits light onto the reflecting surface. The light sensing means senses the reflected light, and the Peltier junction selectively heats and cools the reflecting surface causing moisture to condense on the surface which changes the reflecting properties of the surface and changes the amount of light to the light sensing junction. Current through the Peltier junction is then switched causing the Peltier junction to heat the reflecting surface evaporating the moisture.

A flap system is attached to the rear end of the body of the vehicle and adapted to be moved by air currents on the first side of the vehicle body to a position on a second side of the vehicle body for putting a drag on the second side thereby preventing side sway of the vehicle.

Abstract: An inverter ballast for fluorescent lamps utilizing a resonant circuit coupled to the lamp and operated from a source of DC power through transistors. The transistors are controlled by a sensing means in the resonant loop which insures that the transistor switch at zero current. Furthermore, the coupling means for the load controls a source of heater voltage to the anodes of the fluorescent light which operate at very low current, an antisaturation circuit made up of separate windings are on the current transformer and connected to the switching transistor bases and through diodes to the power supply to prevent "shoot through" current in the transistors. An autotransformer is used as a high leakage reactance transformer; and a circuit is provided to prevent overload of the resonant circuit in case of lamp failure. Shoot through currents are prevented, and overload of the resonant circuit is prevented, and an autotransformer coupling of the resonant circuit to the load is used.
