Title: Hot melt adhesive for elastic banding and method for utilizing the same
Inventor: BUNNELLE W
IPC: B32B25/10
Filed: 1979-09-21
Abstract: A purpose of the disclosed method is to impart gathers and elasticity to a relatively inelastic film, membrane, or web substrate, through elastic banding with a viscoelastic hot melt pressure-sensitive adhesive (PSA). Typically, the resulting elastic-banded substrate product (e.g. 40) will be cut into discrete units and formed into garments or body-encircling members such as disposable diapers. One step of the preferred method involves extruding a ribbon or band (13 or 113) comprising a viscoelastic hot melt PSA, which PSA has unusually high cohesion, stretchiness, and elasticity without excessive loss of adhesive bonding strength. (The viscoelastic behavior of the PSA is believed to be determined, at least in part, by the relative size of its crystalline domains and its rubbery domains and the glass transition temperatures and softening points of its components.) A second step of the preferred method involves bringing the band of hot melt (13 or 113) into adherent contact with a surface of a moving continuous substrate (22 or 32 or 132). A typical substrate would be the polyolefin film used in the manufacture of disposable diapers. The band can be bonded to the substrate through a pressure activation technique, wherein the band itself has the necessary inherent adhesive properties.

Abstract: A metal current collector substrate adapted to be inserted into an elongated cylindrical housing (2) of a primary electrochemical cell (1). The metal current collector substrate (20) is employed together with porous carbon and fiberglass separator elements to form a carbon current collector electrode/separator assembly for use in the electrochemical cell. The metal current collector substrate (20) in accordance with the invention comprises a thin, circular, metal disc (e.g., of nickel) having a plurality of curved notches (20b) around its periphery. The notches are equally spaced about the periphery of the disc (e.g., at 45 intervals) and define a plurality of deflective, resilient arcuate portions (20c) intermediate to the notches. Prior to insertion into the housing of the cell, the disc is flat and has a diameter greater than the internal diameter of the housing. The disc is inserted into the housing by pushing the disc longitudinally into the housing whereupon the arcuate portions (20c) are deflected upwardly by physical contact with the interior wall of the housing (2). This deflection causes the arcuate portions to move toward each other and in turn to cause the disc to generally conform to the interior cross section of the housing. The arcuate portions following the deflection thereof are at acute angles with respect to the interior wall of the housing and make direct physical contact with the wall of the housing. In addition, due to the adjacency of the notches in the disc to the wall of the housing, a plurality of passageways are established between the disc and the interior wall of the housing.

Abstract: An air cleaning apparatus is disclosed in several embodiments. In one set of embodiments there is described an air cleaning apparatus (20) in which air to be cleaned is drawn toward and through a filter (41, 42, 43) in a particular direction. Periodically, reverse pulses of air are directed through the filter (41, 42, 43) in a direction opposite to the normal flow to interrupt the flow of air and to dislodge collected particles from the uncleaned air side of the filter and to enable migration of the particles towards the downstream lower end of the filter (32). In accordance with other embodiments of the present invention, there is described the addition of inertial precleaner devices (319, 319a, 319b) located proximate the unfiltered side of each filter for inertially separating heavy particulate matter from the uncleaned air prior to filtration. In addition the inertial precleaner devices (319, 319a, 319b) may have closure means (328a, 261a, 514) operable during the periodic reverse pulse cleaning to remove the dislodged collected particles and prevent reentrainment on the filter (286, 306).

Title: High speed data bus structure and system
Inventor: MCFARLAND HAROLD L JR
IPC: G06F13/42
Filed: 1982-10-19
Abstract: A high speed data bus system for communication among various functional units (10). The functional units are mounted in immediately adjacent connectors (25) on the backplane (Fig. 4) to define a populated section of effective characteristic impedance Z0' and one or two unpopulated sections of impedance Z0. A populated end of the transmission line (40) is resistively terminated with a resistance corresponding to Z0' (65) while the unpopulated end is terminated with a resistance corresponding to Z0 (67). The border between the populated and unpopulated sections is terminated with a resistance corresponding to 1/(1Z0'-1/Z0) (68), thus eliminating signal reflections. Driver gating circuitry (Fig. 9B) responsive to first and second data input signals, an enable signal, and a conditional inversion input signal performs multiple levels of gating with minimum of propagation delay. The preferred differential receiver (Fig. 10B) amplifies a relatively low level differential input signal and performs an exclusive OR function with a conditional inversion signal. To implement the indivisibility of transfers the control logic for each port includes screening circuitry (190) responsive to the state of the port's buffers (180), and further responsive to flags from the functional unit for selectively accepting or rejecting bus information, and further includes screening constraint circuitry (230) ensure that the port accepts all or none of the information that makes up the transfer. Depending on the flag, the rejection may be total, or may apply only to a designated class of transfers.

Title: Pumping apparatus
Inventor: SIMMONS EUGENE D
IPC: F04B47/08
Filed: 1985-10-18
Abstract: A pumping apparatus (10) which includes a downhole reservoir unit (20), a pumping unit (18) and a power unit (102). The reservoir unit (20) has a piston assembly (70) with a top piston (72) and a bottom piston (74). A storage chamber (82) is defined between the two pistons (72, 74) which is variable in volume as the piston assembly moves from the rest position to a pumping position where a helical spring (98) is compressed. The piston assembly (70) is moved by fluid in a tubing string (22) through reciprocal motion of a pulser piston (48). As the piston assembly (70) is moved downwardly, fluid from the reservoir passes through a check valve into the storage chamber (82). When the piston assembly (70) is in the pumping position, the pulser piston (48) is retracted and the helical spring (98) drives the piston assembly (70) upward. The volume of the storage chamber (82) decreases and fluid is pumped from the storage chamber through the tubing string to the surface. The movement of the pulser piston is controlled by a double acting hydraulic cylinder assembly (30) which has a stroke sufficient to move the piston assembly (70) between the rest and pumping position despite the presence of gas in the fluid in the tubing string (22). The fluid pumped from the reservoir can be used to cool the hydraulic fluid in the hydraulic fluid reservoir (108).
