Abstract: Electrical testing apparatus comprising a pair of input probe terminals, a multi-position mode selection switch, a source of direct voltage, an NPN transistor and a PNP transistor, and a pair of light-emitting diodes each connected in the collector-emitter circuit of a corresponding transistor and poled for conduction when the corresponding transistor is on. In one position of the switch connecting one of the input terminals to both bases of the transistors, an alternating voltage between the input terminals is indicated by both of the light-emitting diodes being energized, and a direct voltage between the input terminals is indicated by only one of the light-emitting diodes being energized, the particular one being determined by the polarity of the direct voltage.

Abstract: The invention relates to a method of fastening electrical wire leads to each end of a ferromagnetic sleeve or core form in a manner whereby significantly greater bonding strength is provided between the leads and the core as compared to prior art methods. The core and wire leads are placed in a molding cavity into which molding material is injected so as to affirmatively fill the clearance between the lead ends and the core thereby resulting in a highly effective cementing of one to the other. The core body is hollow so that the molding material passes through each end to completely fill the central portion of the core. In this manner the central bore through the core body provides effective gating to the injected molding material. The ferromagnetic coil article so formed includes a molded flange on each of its ends which extend radially outward from the outer surface of the core body associated therewith.

Abstract: A peroxy catalyst activator is dissolved in a methyl methacrylate, ethyl methacrylate or styrene lacquer containing, in addition, an adhesion promotor, e.g., an acrylic or methacrylic compound such as the carboxylic acids, amides esters having in the ester moiety amino groups or epoxy groups. The lacquer comprises a copolymer of the monomers dissolved in a volatile liquid solvent such as a mixture of toluene and isopropanol. In use, the lacquer containing the activator is applied to at least one of two substrates and allowed to dry. Thereafter, an adhesive composition containing peroxy catalyst is applied to at least one substrate and both substrates are brought into contact and held until the adhesive bond is formed.The lacquer acts to seal porous substrates and permits the cure to take place rapidly without air inhibition. It forms a surface which retains its activity over a long time period, running into years. Thus, component parts may be coated with the lacquer and stored until needed.

Abstract: Ground preparing apparatus for seed planting comprising a frame adapted to be drawn along a field by a tractor or the like connected to the leading end of the frame and with a planting machine connected to the trailing end of the frame. A colter disc rotatably carried by the frame penetrates the ground to form a slit in the ground and cut stalks and like debris. A pair of laterally and longitudinally spaced narrow tooth elements carried by the frame between the colter disc and the trailing end of the frame penetrate the ground on opposite sides of the slit and cut the ground to form a band-like region of ground prepared to receive seeds and the like dispensed by the planter. A pair of wheels rotatably connected to the frame contact the ground and are located between the tooth elements and the trailing end of the frame and are laterally spaced from the band-like region for controlling the depth of penetration of the colter disc and tooth elements into the ground.

Abstract: A top insertion, tray stacking wire with coplanar feet extending outwardly in opposite directions at the bottom of the wire with a prong extending laterally outward from the end of each foot at a substantial angle to the plane of the feet. The wire is held in a horizontal disposition for insertion of the feet and attached prongs into a slot aperture in the top edge of a corrugated paperboard tray and the like having a double wall construction. The wire includes a U-shaped body attached to the divergent feet wherein the legs thereof resiliently separate from one another to abut the ends of the slot aperture with the divergent wire feet projecting underneath the ends of the aperture. While the U-shaped body is being pivoted to assume a vertical orientation, the prongs bite into the corrugations of the adjacent wall, simultaneously pressing the pivoting feet into firm engagement against the wall adjacent thereto whereby the stacking wire is maintained in a firm, upright disposition.

Abstract: A method and apparatus for controlling the supply of alternating electrical power to the electrodes of an electrical glass melting furnace in a manner eliminating or significantly minimizing any d.c. component. Reverse-poled controlled rectifiers are connected between an a.c. source and the electrodes to provide successive periods of alternating electricity to the electrodes, and the firing or gating of the rectifiers is controlled by a circuit in a manner causing each succeeding period of alternating electricity supplied to the electrodes to begin with a polarity opposite that of the alternating electricity supplied during the immediately preceding period. Any d.c. component will be cancelled to zero when averaged over two adjacent periods.

Abstract: A process for purifying water containing fluoride which comprises precipitating fluoride from the water as fluorapatite in the presence of a bed of seeding composition. Fluoride is removed as fluorapatite by having sufficient available calcium for each mole of fluoride present in the water and sufficient available phosphate for each mole of fluoride in the water to form a precipitate which is or converts to sufficient fluorapatite to remove essentially all fluoride from the water.

It relates to a one-man submersible characterized, firstly, by external shapes designed to prevent any accidental fouling with any fixed obstacles; secondly, propulsion and steering units which give it excellent maneuverability and the possibilities of quick neutralization of any reaction experienced by the submersible; thirdly, by the fact that the operator has available a system comprising, at the extreme forward part of the submersible a swivelling and extensible tool-holder system with a coaxial and protected swivel seat; finally, a tall horizontal crane with one or two swivelling and extensible jibs, and four hydraulic columns with a special baseplate, these all being features which enable any work to be carried out with increased rapidity, accuracy and safety.The above submersible has numerous advantageous applications in various areas of ocean exploration and working.

Abstract: This invention relates to pressure regulators used in scuba diving wherein a pressure sensing means is employed to actuate an associated valve member for controlling pressure in the regulator. Specifically, the instant invention relates to that portion of the regulator housing including biasing means operably connected to said pressure sensing means wherein a pressure relief opening is provided in the regulator housing so as to expose the biasing means to ambient pressure conditions. The instant invention teaches the provision of a pressure bleed means for transmitting pressurized air through the regulator housing portion including the biasing means and outwardly through said relief opening. By this arrangement ambient water may not pass into the regulator housing through said relief opening which could otherwise result in potentially adverse effects on the operation of the biasing means.
