  • Patent number: 4676528
    Abstract: A tubular upset extension apparatus which prolongs the usefulness of upsetted tubing joints used in drilling oil, gas and water well bore holes. The upset extension apparatus is fitted onto hollow bore tubing having shortened and specially threaded box and pin joints and a beveled peripheral shoulder at the inner terminal of the threads. The upset extension apparatus likewise has a hollow bore and specially threaded male and female ends which are rotatably engageable with the shortened tubing upsets. An exterior, non-bore penetrating circumferential groove is defined by the point of intersection of the shoulders of the upset extension and the shortened tubing upset. The circumferential groove receives a cosmetic weld, non-thread and non-bore penetrating weld which rigidly secures the upset extension to the shortened upset and maintains the internal and external integrity of the engaged sections.

  • Patent number: 4651157
    Abstract: A method and apparatus for positively indicating the position of a land-based vehicle, a marine vessel or an aircraft, utilizing a security system provided in the secured mode of transportation monitored by a central station. Navigational information transmitted by LORAN-C transmitters or satellite transmitters are received and then retransmitted to the central station which determines the exact latitude/longitude coordinates of the secured mode of transportation. The secured mode of transportation also includes a security panel for monitoring the condition of various parameters. An interface is connected to the security panel and the navigational receiver for coordinating the transmission of information relating to the conditions monitored by the security panel as well as the information received by the navigational receiver before they are sent to a radio for transmission to the central station.

  • Patent number: 4622536
    Abstract: An algorithmic analog-to-digital and digital-to-analog converter 10 combines the techniques of switched capacitor cyclic conversion by using first and second amplifiers 31, 32 with capacitors C.sub.1, C.sub.1 ', C.sub.2, C.sub.2 ', C.sub.3, C.sub.3 ', C.sub.4, C.sub.4 ', C.sub.5, C.sub.5 ' communicating with the inputs of said amplifiers 31, 32 and between the inputs and outputs of said amplifiers 31, 32, and the techniques of reference voltage refreshing. The performance of the converter 10 is capacitor ratio-independent. Because of the ratio-independent aspect, very small component values can be used, and as a result, the die area required for the circuitry can be quite small.

  • Patent number: 4451941
    Abstract: A sanitizer dosing dispenser for immersion in a body of water such as a toilet tank whose water line can be lowered from an upper level to a lower level by flushing, which includes a product chamber for containing a solid, water soluble material, first and second walls defining a first flow path therebetween for providing a predetermined volume of water from the body of water to the product chamber along the first flow path in response to the level of the body of water falling from the upper level to the lower level. The first wall is flexible and located so that hydrostatic pressure from the body of water presses the first wall against the second wall to close the first flow path against water flow therealong when the level of the body of water is above the first wall, and permits the predetermined volume of water to flow into the product chamber to dissolve a portion of the soluble material therein when the level of the body of water is below the first wall.

  • Patent number: 4324078
    Abstract: Apparatus for fireproofing an underfloor access chamber of an electrical wiring distributing floor structure. The access chamber is formed between a cellular unit and a covering layer of concrete. The access chamber has at least one inlet opening communicating with a raceway presented by the cellular unit; and an outlet opening providing access to the chamber from the space above the concrete. An unobtrusive strip of fire-resistant material, disposed within the chamber, covers substantially entirely all of the bottom portion and obstructs the inlet opening. The strip shields the upper portion of the chamber from heat transfer by convection and by radiation. Slit means formed in the strip allows passage of wiring without significantly deteriorating obstruction of the inlet opening.

  • Patent number: 4234331
    Abstract: A method of applying a metallic oxide coating to a moving ribbon of glass is disclosed for four thicknesses of glass, namely, 7/32; 3/16; 5/32 and 1/8 inch. In each of these methods, first and second spray zones are established at opposite edges of the moving ribbon. The spray zones are moved in a simultaneous manner at the same speed from one edge to the other edge whereby the spray zones pass each other at the center line of the moving ribbon. When each of the spray zones reach the opposite edge of the moving ribbon, their direction of travel is reversed so that they once again pass one another at the center line of the moving ribbon. The first and second spray zones are spaced a slight distance from one another in the direction of movement of the moving ribbon. The moving spray zones are cycled back and forth in the aforedescribed manner continuously as the ribbon of material is moved thereunder so that a coating is applied to the moving ribbon.

  • Patent number: 4233933
    Abstract: This disclosure is directed to a machine for applying a spray coating across the width of a glass ribbon. The glass ribbon is one which generally has recently been manufactured and is carried on a conveyor moving below the machine. In accordance with the preferred teachings of this apparatus, two spray applying devices are used. These devices commence their spraying at opposite edges of the moving ribbon of glass. The devices are moved in a simultaneous manner at the same speed from one edge to the other edge of the glass ribbon whereby the apparatus pass each other at the center line of the moving ribbon. When each of the spray apparatus reach the opposite edge of the moving ribbon of glass, their direction of travel is reversed so that they once again pass one another at the center line of the moving ribbon. The first and second spray apparatus are spaced a slight distance from one another in the direction of movement of the ribbon of glass.

  • Patent number: 4232493
    Abstract: A floor structure comprising a metal subfloor including metal cellular units providing plural enclosed cells; housings associated with certain of the cells, each adapted to provide future access to different electrical services at one location in the floor structure; a covering layer of monolithic concrete covering the subfloor and the housing, and a layer of fireproofing material covering the lower face of the metal subfloor. Activating means is provided establishing access to the enclosed cells through the housing without significantly reducing the desired fire endurance of the floor structure and without increasing the thickness of the layer of fireproofing material. The fireproofing material has a thickness which is less than that required to provide the floor structure with a desired fire endurance when the housing is activated. A method is disclosed for establishing acess to the enclosed cells through the insert while maintaining the fire endurance capability of the floor structure.

  • Patent number: 4200863
    Abstract: An array of binary weighted capacitors, an additional capacitor having a capacitance value equivalent to that of the least of the binary weighted capacitors, a voltage comparator, switches for interconnecting the capacitors with certain predetermined voltage levels and the comparator, and a sequencing circuit are included. One side of all of the capacitors is connected to one input terminal on the comparator and the other side has applied thereto the signal to be quantized. Switch sequencing combines divided portions of a reference voltage with the signal to be quantized for presentation to the input of the comparator which thereby provides a serial digit output connected to the sequencing circuit. In this fashion, a linear conversion between an analog and a digital signal is made by the sequencing circuit. A nonlinear converter between digital and analog signal presentation is also disclosed.
