Abstract: A metal framing system for building structures wherein the members have continuously roll formed and fabricated "C"-shaped, "T"-shaped, and "I"-shaped cross sections and wherein the flanges at their distal edges excluding plate members, include a roll formed multi-purpose end and surface fastener recess extending the length of the member. These recesses are adapted to supportedly receive threaded fasteners for use in conjunction with both interconnection of pre-punched transverse plates at the ends of the members and also for attachment of wall covering against the flanges of the members. This recess and extended distal edge, while providing full functional flange width, also eliminates "Q" column flange loss while substantially stiffening the distal edge of the flange. "C" section studs and joists members may have two additional end fastener recesses added to the webs where a total of four fasteners are required per member for attachment to plates.

Abstract: A foraminated cylindrical container has a loading port into which loose fill media may be loaded for cleaning. The container is rotated to tumble the media and a pan for containing solvent is located so that the media will be immersed during rotation. A hose supplied by a high pressure pump is used to further clean the media. The container may be raised and tilted to facilitate removal of the media. The solvent may be pumped from the pan to a storage tank. Separate switches are provided for the pumps and the rotation and hoisting mechanism so that the operator can adjust the timing of each portion of the cycle as needed to complete the cleaning.

Abstract: A heat exchanger for use in a marine air conditioning system is configured to provide the maximum possible heat transfer surface for the air being conditioned. The refrigerant coils and associated fins form the heat exchanger banks as usual, but instead of a single vertical bank, two banks are positioned at an angle to each other. This configuration provides a plenum which is more effective in causing air flow across through the entire heat exchanger configuration than is the case with the thin plenum associated with a single vertical bank. A housing for enclosing the heat exchanger is disclosed, which provides desired air passages.

Abstract: A dispenser of beverages prepared by combining hot or cold water with granulate is disclosed. The dispenser is designed to dispense granulate directly from the container in which it is purchased at retail or from the manufacturer by incorporating a support funnel which will hold the container inverted. The funnel is also designed to catch any spilled granulate and direct it towards the funnel spout. The dispenser may be combined with an instant hot water heater and/or a coin mechanism. A separate control compartment having a closure which is designed to make access more difficult is included in the housing. A more readily available compartment containing the funnel and the granulate container may also be locked. The dispenser provides a freshly prepared beverage without the need to wait for brewing and minimizes cleanup since no brewing container is required.

Abstract: A cover for a boxing glove for holding the thumb enclosure of the boxing glove against the glove. The cover also provides a smooth back for a glove which has been worn and abraded so that the glove can continue to be used without producing abrasions from the worn surface. The thumb holding or retaining portion may be elasticized. Laces or other means may be used to secure the cover to the glove.

Abstract: A building structure is formed using four by eight foot plywood panels as raw material because of their ready availability. Hexagonal pyramids are formed by first cutting a panel diagonally to form two right triangles. These two right triangles are joined to form a triangular section having a height equal to its base. Six such sections are joined to form the hexagonal pyramids. Pentagonal pyramids are formed by cutting the panels using the eight foot lengths as the dimension of the hypotenuse. Each panel can produce two triangles and they are combined to form an equilateral triangular section. Five of these sections are combined to form each pentagonal pyramid. Reinforcement pyramids are joined in the interior of each pyramid. These are similar to the pyramids they reinforce, but of one half the size. The pyramids are combined using them as substitutes for the plane hexagonal and pentagonal surfaces of regular and semi-regular polyhedrons.

Abstract: A container, having a sealable closure, has included therein distilled water, one or more aquatic plants, one or more herbivorous fish, an aquatic algae eating animal, inert particulate material and measured amounts of certain elements. The elements are nitrogen, potassium, phosphorous, calcium and magnesium. An air space is left at the top of the container and a pinhole provided in the closure. This shelf perpetuating, sealed aquarium requires no air pump or heater, and fish food is not added; however, sufficient light to maintain the aquatic plants in healthy condition is necessary.

Abstract: A garage door screen system is provided for a sectional garage door of the type which opens to an overhead position while supported by rollers contained in channels. The screen system is for a partially opened garage door and, in the preferred embodiment, provides separate screens for the bottom opening and the opening at the top which occurs as the door panels pivot inwardly. The bottom screen is alternately a rigid panel which is supported by vertical guides to the lowest door panel, or a window shade draw down type. A latch holds the lower rigid screen so that it does not extend below the door panel. When the latch is released, the screen panel will descend. The latch can be re-engaged merely by lowering the door. Torsion springs in the roller mechanism, automatically retract the screen secured to it when the latch holding the screen in its extended position is released. The top screen is attached at its top end to an upper cylinder which is secured to the door frame by pipe clamps.

Abstract: An ozone generator has a central metal bristle brush electrode with a metal cylindrical electrode separated from it by a Pyrex cylinder. The electrodes are contained in a sealed cylinder having an inlet for air at one end and an outlet for ozone containing gas at the other end. A transformer connected to the electrodes provides a voltage high enough to create an ionizing electric field between the electrodes. Ozone generation is initiated in response to a demand for treated water which occurs in one embodiment when a well pump turns on, and in another embodiment when a faucet is turned on. A compressor is used in conjunction with the well pump, and an aspirator is used in conjunction with the faucet.

Abstract: A slipper designed to leave the wearer's toes exposed for enjoyment or for treatment such as a pedicure is provided. The slipper has a sole which may be of flexible and pliable material or may be relatively rigid. A cushioned insole may also be used and connected to the sole. At the margin of the rear portion of the sole, a heel containing means is connected. The heel containing means is formed of a fold of material with the fold being joined to the sole. The free edges of the heel containing means are seamed together while also forming a passage for a tying cord or ribbon. The tying cord or ribbon is made captive in the passage by stitching it to the heel containing means at one point to prevent inadvertant removal of the cord or ribbon therefrom. An adjustable strap is connected to the margins of the sole so as to extend across the instep of the wearer.

Abstract: A packing arrangement for bodies having circular cross-sections of unequal radii is disclosed. The radii of the bodies are proportional to one, two and three. Each body of one radius is adjacent to at least one body of each of the other radii. These bodies either are tangent to each other or at least two lines joining the centers of adjacent bodies will be at right angles to each other. The bodies may be cylindrical or spherical.

Abstract: A cooling wrap is designed for tying around the neck of a person while performing vigorous activity in hot weather. A closable bag for containing a frozen water medium is stitched in a pouch formed in a strip of water pervious fabric. The strip of fabric is further stitched to form tying straps on both ends of the pouch. A pad of open-pored foam is secured in the bag to insulate the neck from severe cold while still permitting the controlled dispensing of water to the neck. The frozen water medium may be ice, but is preferably open-pored foam which has been saturated with water and frozen.

Abstract: A suction cup is used to attach one end of a light conveying conduit to the headlight (or other light) of a motor vehicle while the other end of the conduit is positioned in the field of view of the operator of the motor vehicle. The conduit may be rigid with the one end held in a recess in the center of the suction cup. A flexible conduit may also be used with the other end of the conduit held in the field of view by a second suction cup.

Abstract: A catamaran tiller having a grip is provided to permit tension to be applied to the tiller more easily. In one embodiment the grip extends laterally from a sleeve which fits over the tiller rod and is secured thereto at a desired location. Provision is made to have the grip rotatably mounted on the sleeve or for the sleeved to be secured with the grips in alternative positions. A circular grip is also disclosed.

Abstract: A flow regulator valve has a first fluid opening at one end and a second fluid opening at the side of the valve body. A sleeve bore extends from the first opening and contains a stem which is co-axial with the sleeve bore, but spaced from it. A compensating spool is slideably mounted between the sleeve bore and the stem and may move to completely close the second opening or to provide partial opening. A control spring biases the spool to the open position, but a fluid passage through the stem wall permits the pressure of the fluid at the first opening to be applied to bias the spool to the closed position. A valve element containing an orifice establishes the nominal flow rate desired, while the pressure drop across the spool causes it to assume a position to maintain the desired flow rate. A valve element control spring may be used to maintain the valve element in the "off" position until the pressure rises to a desired threshold. Venting of the cavity in which the valve element is located is provided.

Abstract: A standby aquarium pump is disclosed which contains a direct current power supply and relay means which will automatically connect this power supply to start the standby pump when alternating current power is interrupted causing the AC powered pump to stop operating. An alternate embodiment provides rectified alternating current as the normal power supply and the direct current power as a standby or auxiliary power source. A rotary direct current motor is employed to drive a reciprocating piston type air pump using an operating rod eccentrically mounted in a flywheel mounted on the motor drive shaft. Electric shock hazard is reduced by containing all 120 volt alternating current connections in a separate housing secured to the main housing. Thus, the main housing can safely be opened to install or replace the batteries by the user who will be exposed only to the low voltage direct current elements.

Abstract: Rental equipment such as television sets are provided with a timer which operates a relay to connect power to the equipment only during the time for which rental has been paid. The timer includes a magnetic reader head and decoder to produce digital signals corresponding with a magnetic strip which has been encoded with rental period and identifying information at the location where the rent is paid. The timer contains a real-time clock and a microprocessor to compare the current time with the time in the rental period. A power supply for the timer derives energy from the same power lines used for the rental equipment, but a battery is also provided to power the clock alone when the power supply is not energized. Displays of the current time and rental expiration time are provided, as well as visible and audible alarms to warn of the approach of the end of the rental period.

Abstract: A calibrated handknob assembly for use with a valve having a control stem, said assembly having a rising stem with spaced circumferential calibrations, a handknob having circumferentially spaced radial calibrations, a lock ring having an index cooperating with said handknob calibrations and having positions for permitting setting of the handknob "zero" position and index position at a desired circumferential location, for placing the assembly in a condition where the handknob cannot be rotated and for permitting rotation of the handknob to change the valve opening. An O-ring is used to detent the lock ring so that inadvertent rotation of the handknob will not occur and to prevent movement of the lock ring to the position where the handknob can be removed and "0" calibration reset. The O-ring may be easily removed to permit the resetting when needed.

Abstract: Two metal blocks, each having a cylindrical passage containing a rod, and a slot extending from one side to the cylindrical passage, also have a hole extending across the slots. A threaded member passes through the hole in one block and into threads contained in the other block beyond the slot. A compression head is mounted on the other end of the threaded member and is provided with a handle. When the handle is turned to advance the threaded member, the slots tend to close somewhat preventing movement of the rods in the blocks. When the threaded member is withdrawn slightly, the rods can be moved to desired positions relative to the blocks and the blocks can be rotated relative to each other.

Abstract: Epoxide compounds can be cured without resorting to the usual elevated temperatures by reducing the ambient pressure to 4.79 Pa or lower. This is particularly useful in potting circuitry.
