Abstract: A connector block including wire-formed multiple solderless connectors. The block has retainer and body sections with slots and bridge elements to house and define rows and columns of the connectors. The block is further provided with wire wrap pins which project from one side of the block and which are in mechanical and electrical contact with the wire formed solderless connectors.

Abstract: An improved fiber reinforced material for use in the manufacture of gaskets is produced by impregnating a nonwoven fabric with an aqueous dispersion of a rubber and filler. The water is then evaporated out of the impregnated fabric. The final product is formed by curing the rubber under heat and pressure.

Abstract: A membrane switch assembly having an apertured air permeable spacer positioned between a pair of printed circuits. Air may diffuse through the permeable material into and out of the regions which define individual switch cavities during operation.

Abstract: A drill rod, left in place in the plug of a taphole of a shaft furnace, is withdrawn by apparatus including a conventional percussive type taphole drill which is movable along a support bar. The support bar is provided, at the end which most closely approaches the furnace, with a guide and support head which engages and supports the drill rod as it is being withdrawn subsequent to loosening from the plugging material in the taphole.

Abstract: Entrained particulate matter is separated from the pressurized gas released from an intermediate charge material storage hopper of a blast furnace charging installation, the hopper alternately being pressurized to the furnace pressure for release of charge materials into the furnace and the pressure being relieved to atmospheric to permit reloading, at a point upstream of the filters and/or silencers through which the pressurized gas is released to the ambient atmosphere. The separator comprises a series of perforated discs, which may be heated, associated with a collection chamber into which separated material will fall under the influence of gravity.

Abstract: An electrical switch assembly of the type comprising a pair of printed circuits separated by an apertured spacer wherein passages are provided to vent gas from the region of each individual switch and the edge of the assembly.

Abstract: Improved mold structure and method of molding for mechanically frothed urethane foams is presented. The mold is filled from the bottom via an annular runner which communicates with the mold cavity. The connection between the annular runner and the mold cavity is restricted to create a back pressure in the circumferential runner.

Abstract: A tool for inserting a wire between resilient contact portions of a connector. The tool has a handle portion and a reversible stem portion and the stem portion includes a blade extending from opposite sides thereof. The blades are generally in the form of I-beams and, in use, the channels at either side of the beam engage the connector contact portions while the web portion of the beam serves as anvil which supports the wire in the region between the contact during insertion.

Abstract: An improved mattress is presented having upper and lower elastomer sheets with an undulating structure of elastomer elements housed between the sheets and containing stiffener elements in the elastomer elements.

Abstract: Plural gas samples are simultaneously collected and the temperature at each sampling point accurately measured by means of a probe which may be inserted into the furnace charge. The probe is constructed so as to facilitate assembly and repair while insuring against relative motion of the various components thereof as a result of imposed vibrations and thermally induced expansion.

Abstract: Structure for and a method of construction of miniaturized bus bars are presented wherein the bus bar incorporates discrete high capacitive elements between a pair of bus bar conductors, the high capacitive elements being defined by wafers of material having a high dielectric constant coated with layers of conductive polymer. The conductive polymer is used to bind the chips between the bus bar conductors.

Abstract: Various structures for and methods of constructing miniaturized high capacitance bus bars are presented. The bus bars incorporate discrete high capacitive elements between a pair of bus bar conductors. Alternate arrangements are presented wherein the capacitive elements are maintained in electrical contact with the conductors while avoiding the development of short circuits between the two bus bar conductors.

Abstract: A membrane switch assembly wherein the internal pressure is automatically equalized with the external pressure through the use of a self-regulating vent. The vent is defined by a non-linear slit formed in an outer layer of the membrane switch assembly, the slit producing a normally closed valve which is caused to open by a pressure differential between the internal pressure and the external pressure.

Abstract: A miniaturized bus bar and the method of production thereof wherein a sheet of insulating material is laminated between a pair of bus conductors and windows are provided in the laminated structure. A plurality of multilayer ceramic capacitors are inserted in the windows and alternate plates of the capacitors are electrically connected to the two bus conductors. The capacitors are comprised of alternating layers of conductive material and dielectric material.

Abstract: A pulverized material, particularly coal or lignite, is maintained in a fluidized state in a storage container and is released therefrom into a carrier gas stream. The gas for causing fluidization and maintaining a pressure in the container which is greater than the carrier gas pressure is in part obtained by recycling gas vented from the container, the vented gas being filtered and increased in pressure. The vented gas may also be employed to aid in the delivery of the pulverized material into the container.

Abstract: A miniaturized bus bar is presented wherein a plurality of distribution prongs or fingers are mechanically and electrically bonded to a ribbon type capacitor which is defined by a pair of bus conductors and a ceramic spacer.

Abstract: The invention relates to a low current, low voltage generator for use in an underwater lighting system. The generator is driven by a commercially available source of power, for example, house current. The generator consists of an AC motor having an output shaft and a magnet mounted on the shaft for rotation therewith. A coil arrangement is disposed in a plane parallel with but spaced from the plane of the magnet. The magnet is cylindrical in shape and includes a slot in the front face which faces the coil arrangement. Thus, when the magnet is rotated, it produces an EMF in the coil arrangement to provide a low current low voltage AC output at the output of the coil arrangement, which can be rectified to provide a DC output if required.

Abstract: A modular block, base and bracket assembly is presented for effecting electrical interconnections. The bracket is configured to receive one entire block and part of another block so that brackets can be mounted in series whereby three blocks can be mounted on two brackets.

Abstract: Compounds having the following general formula: ##STR1## wherein R is an alkyl or aminoalkyl group having 1 to 8 carbon atoms, or a hydrogen atom; R.sub.2 and R.sub.3 are either hydrogen atoms or, together, an additional carbon-carbon bond, as well as the mineral or organic acid addition salts thereof. These compounds are used as anti-arhythmic agents.

Abstract: A gasket material comprised of fibrillated aramid fibers, diatomaceous earth and either a polyethylacrylic or polybutylacrylic latex alone or in combination with conventional curatives, antioxidants and pigments. The constituent materials are combined in a beater-addition process, and the pliable gasket material is then formed on conventional paper making equipment.
