Abstract: An invention in a golf swing trainer device having a weighted head with an appearance that is similar to an enlarged iron golf club, and includes a shaft that is bent oppositely at spaced apart points therealong, to off-set a lower shaft portion outwardly from an upper shaft portion. The head is secured on one shaft end and a hand grip is telescoped over the other that includes contoured depressions to accommodate a golfer's fingers closed therearound and has elevated portions for fitting the V areas between the thumb and forefinger of a golfer's hands therealong, the grip for exactly positioning the golfers hands relative to the trainer shaft and head. The weighted head is formed from a metal rod that is bent into the general shape of a head of the enlarged club iron, such that the weight thereof will be centered outwardly and above a head center point and is open to provide a minimum air resistant when the trainer is swung.

Abstract: A reciprocating piston electrical motor includes at least one nonmagnetic cylinder housing forming a piston chamber wherein a magnetic piston is freely slidably mounted. Spaced separate coils of wire are wrapped about respective ends of the cylinder housing leaving the intermediate length of the cylinder free of windings. One end of a piston rod is rigidly attached to the magnetic piston and the other end is rotatably attached to a crankshaft. The crankshaft is rotatably secured to a mounting base while the end of the cylinder housing away from the crankshaft is pivotally mounted to the mounting base. Means are provided for supplying electrical power to the coils to cause movement of the magnetic piston first to one end of the piston chamber and then to the other.

Abstract: A pipe-supporting device adapted to receive and support an exposed pipe on a roof has a substantially flat bottom for resting on the roof and an upwardly tapered structure secured on and rising from the base to provide a pipe positioning and supporting structure which substantially equally distributes the weight of the supported pipe over the area of the base in contact with the roof. The pipe positioning and supporting structure has a pocket for positioning a pipe therein and the pipe is supported in the pocket by at least one roller positioned in at least one receiving trough. As the pipe expands or contracts, it rides on the roller which rotates within the trough.

Abstract: A process for dense packing on a conventional pallet three-cubic-foot bags containing a lightweight, loose material that will flow within that bag, by a stacking pattern where a pair of bags are arranged alongside and offset from one another on the pallet to make up each stack layer, with successive layers rotated ninety degrees (90.degree.) from the layer below; applying, in turn, to each bag a downward force, as by a person moving his feet thereon, to evacuate air from that bag and to shift the contents to fill in gaps or openings in the layer below; and securing that stack to the pallet for transport; and a stack of three-cubic-foot bags containing a lightweight, loose material by a practice of the process of the invention.

Abstract: An apparatus and method for placing information on film takes advantage of the chemical memory of the film to use low cost displays and interface circuitry capable of displaying only a limited number of informational characters to place more than those limited number of characters on the film. This is achieved by sequentially exposing at least two separate sets of a limited number of characters on different portions of the film.

Abstract: In a system of computers interconnected for communication between any two or more of the interconnected computers, such intercommunication being in packets of information in a standardized format normally at a standardized speed, a standardized location within the format is provided to contain information that may be used to change the intercommunication speed for the remainder of that particular packet.

Abstract: A foot support for use in a shower stall or bathtub enclosure during showering, whereon a person can rest or support his foot while applying soap thereto, the support including a series of indentation therein that confirm to a bather's foot, either left or right, wherein the foot is rested and supported as it is soaped, eliminating slippage thereof as it is pivoted and canted as it is washed.

Abstract: An electrowinning cell has anodes shielded by an electrical-flux-impervious, electrically non-conductive material which protectively covers each of the anode suspension members and adjoining upper margins of the main body of the anodes. At least one electrical-flux-pervious opening of proper shape, size, and appropriate position to permit sufficient current flux to flow to an associated cathode to induce a uniform current distribution on the upper portions of the cathode is provided for each suspension member. The resulting uniform current distribution insures deposition of highly pure metal values of uniform thickness without the usual undesirable extraneous formations on the top edge of the electrowon metal cathode. The shielding material may be applied to an anode before attachment to its hangerbar for suspension in an electrowinning cell or may be applied to an anode which is already in service.

Abstract: A solid state graphite electrode to determine the activity of an ion-specie in solution. The graphite electrode of the present invention can be adapted for use as either an external reference electrode, an ion-selective electrode or as an internal reference electrode. The electrode includes, as an electrically conductive element, a supported section of graphite that is appropriately electrically connected through a potentiometer to show a difference in ion concentration as a voltage potential or emf. One graphite surface for immersion in a test solution is hydrophobized by coating it with a solution that contains an organic liquid molecule to covalently bond with hydroxyl groups (OH) of the graphite surface, rendering that surface hydrophobic. Preferably, the organic liquid is a silanizing agent, which coating after drying is covered with a hydrophobic layer or membrane that is preferably a polyvinylchloride (PVC) plastic.

Abstract: Means are provided in combination with the depending cylindrical skirt of a drill rig for conveying drill cuttings from around the drill stem during a drilling operation so they will not deposit in the usual annular pile around the open mouth of the drill hole. The means comprise a hopper attached to the lower end of the skirt and having a side discharge opening into which one end of an endless conveyor protrudes in confronting relationship with the drill stem that passes through an accommodating opening in the otherwise closed bottom of the hopper. The conveyor is advantageously of scraper type, having an endless chain with scraper blades at intervals along its length that scrape along the bottom of a conveyor trough, and advantageously having an elongate discharge opening extending lengthwise of the bottom of the trough adjacent to the discharge end of the conveyor.

Abstract: A diaper for use upon an infant, comprising a sealed chamber for retaining excess liquids, formed between two moisture impervious sheets spaced apart by absorbent wadding, the innermost sheet having an opening therethrough for entry of the liquids into the reservoir. The diaper may further comprise a layer of conventional diaper wadding on the inside face of the innermost impervious sheet. The liquid capacity of the chamber is substantially greater than that of conventional wadding alone, so that diaper changes are needed less frequently. The infant is substantially protected from wetness by the barrier sheet.
