Abstract: An apparatus for directing and controlling the flow of water between the supply and return of a solar collecting device, the cold water inlet and hot water outlet of a water heater and the cold water source and hot water feed of conventional household plumbing. The Water Flow Controller Device includes a cold water source connector, a hot water feed connector, a collector supply connector, a collector return connector, a cold water inlet connector, and a hot water outlet connector. The hot water outlet connector is bifurcated to provide independent water flows paths for the hot water and the collector return water. The Water Flow Controller Device circulates water through a connected solar collecting device when the temperature at the output of the solar collecting device is above the temperature of the water at the bottom of a connected water heater.

Abstract: An apparatus for the solar distillation of contaminated water which includes a substantially airtight enclosure having an evaporation chamber and condensation chamber. The evaporation chamber has a lower reservoir and an upper inclined surface which is transparent to solar radiation. The condensation chamber includes a thermally conductive condensation wall and a collecting reservoir for collecting the condensed water. A thermal insulative partition is located intermediate the evaporation chamber and the condensation chamber, and includes an upper port and a lower port. At least one thermally conductive conduit may be located within the condensation chamber and externally vented at the upper and lower portions thereof.

Abstract: A new business form having integral therewith a mailing envelope, a customer statement, and a return envelope. The new business form includes an outer sheet having a releasable bisecting center line dividing the outer sheet into and forming thereby a first side and a second side, and an inner sheet which is secured to the first side along three edges thereof to form the return envelope. The second side is adapted to receive customer information and function as the customer statement. The outer sheet is folded on the bisecting center line and releasably attached along the outer edges of mating surfaces of the first side and the second side to form the mailing envelope. The improved business form may be one of a continuous series of improved business forms which are adapted for use on high speed data processing equipment.

Abstract: A method and apparatus for modulating the perceptible intensity of the presentation of a light emitting display which light emitting display emits light by gas discharge and recombination of ions and free electrons of a display medium; includes a system clock, the interruption of which causes the interruption of the presentation of the light emitting display; and is capable of retaining display information upon the interruption of a light sustaining signal or the electrical power as a result of an accumulation and retention of electrical charge across the display medium.

Abstract: Small highly charged droplets are produced without concurrent production of corona by conducting a liquid to a nozzle having a tip from which droplets of the liquid can exit, and forming a substantially uniform electric field over the surface of the liquid on the tip, the field being large enough to pull off droplets from the tip but not so large as to create corona discharge. Selected gas, solid particulates and liquid mists from gaseous effluents such as are produced by smelters, coal or oil-burning steam generators, chemical refineries and the like are removed by means of a unique electrostatic collector using the highly charged droplets. These droplets are caused to drift, by means of an electric field, through the gaseous effluent to a collecting electrode absorbing selected gases and aerosol particles and carrying them to a collecting electrode.

Abstract: An improved constraining grate adapted to alleviate vibration, rattle, and dislodgement of the improved constraining grate. This invention utilizes a circumferentially resilient structure with downward projections which are accepted by holes within the receiving unit and which are bound therein.

Abstract: A fabric marking device for producing a powder mark of predetermined shape and size on pieces of fabric. The device comprises a table with a perforated work surface area and means for delivering powder under air pressure to one or more tubes having a lengthwise slit therein which is placed against a surface of fabric to be marked. Means are provided for altering the angle of the tubes relative to each other, and/or to the fabric to be marked, and for varying the distance between the tubes and work surface to accommodate marking a stack of fabric layers simultaneously.

Abstract: An improved insulator of the type having a dielectric body with a mounting pin below and a mounting cap above, where the mounting cap is capable of receiving and holding the mounting pin, and wherein the improvement comprises an upper metallic bowl-shaped member to dissipate high electric field concentrations and to protect the insulator from contamination, and a lower metallic member to dissipate high electric field concentrations. The insulator is adapted to be linked together with like insulators to form a chain of insulators.

Abstract: An improved rack constraining apparatus especially adapted to alleviate vibration and rattle when a rack, such as an oven rack, is located in an unstable environment, such as an oven within a recreational vehicle. This device utilizes the outer body wires of the rack itself to bind the support rib between the body wire and the rack frame.
