Abstract: An asynchronous, high-speed, fiber optic local area network originally developed for tactical environments with additional benefits for other environments such as spacecraft, and the like. The network supports ordinary data packet traffic simultaneously with synchronous T1 voice traffic over a common token ring channel; however, the techniques and apparatus of this invention can be applied to any deterministic class of packet data networks, including multitier backbones, that must transport stream data (e.g., video, SAR, sensors) as well as data. A voice interface module parses, buffers, and resynchronizes the voice data to the packet network employing elastic buffers on both the sending and receiving ends. Voice call setup and switching functions are performed external to the network with ordinary PABX equipment.

Abstract: A multi-layered, thin-film, digital memory having associative recall. There is a first memory matrix and a second memory matrix.

Abstract: Apparatus for forming and cooking articles made from material of dough-like consistency. The apparatus combines: means adapted to contain a fluid cooking medium at an elevated temperature; an endless belt means adapted to continuous operation having a plurality of convex porous mold members arranged on a surface; a web-like articulated continuous conveyor means adapted to receive finite quantities of amorphous, dough-like material; and means for intermittently positioning consecutive portions of said web-like conveyor means into operative engagement with consecutive mold members to shape each of said quantities of material of amorphous, dough-like consistency into articles of desired configuration. Thereafter the engaged portions of said conveyor and belt means move into said fluid cooking medium containment means.

Abstract: A composition is disclosed in which a solid isocyanate compound such as toluene-diisocyanate dimer is dispersed within a polyurethane based on a hydroxy-terminated organic compound, preferably polybutadiene. The composition can be fully cured on a surface and yet provides an excess of stable material, i.e. dormant isocyanate containing groups, which are reactive on demand to strengthen interfaces with adjacent layers containing available hydroxyl groups, such as a layer of solid polyurethane-based propellant, without the need for intermediate reactive coatings.

Abstract: Dual thrust solid propellant rocket motor is described. The motor comprises a housing having a nozzle, a first propellant grain received by the housing, a second propellant grain arranged within the first propellant grain, and igniter means. The first propellant grain has projections extending into the second propellant grain for positive ignition.

Abstract: A composition and method are disclosed in which a homopolymeric isocyanate such as a toluene diisocyanate polymer is formed IN SITU within a polyurethane composition containing a hydroxy-terminated organic compound, preferably a polybutadiene, an amount of self-polymerizable polyisocyanate in excess of the stoichiometric requirement, and a polymerization catalyst therefor. The composition can be fully cured on a surface and yet provides an excess of stable material, i.e. dormant isocyanate containing groups which are reactive on demand to strengthen interfaces with adjacent layers containing available hydroxyl groups, such as a layer of solid polyurethane-based propellant, without the need for intermediate reactive coatings.

Abstract: A linear retractable seal valve having a wedge sealing-slip assembly slideably held at opposite side edges of the wedge to guide rails of the valve body and moveable from a distant first location to a second location between inlet and outlet ports of the valve from which latter location the sealing slips are wedged outwardly of the longitudinal movement of the assembly into closure engagement with the valve ports, with the valve being returned to its open position through a reverse sequential movement wherein there is first a perpendicular movement of the slips out of closure engagement with the valve ports, following which there is a reverse longitudinal movement of the wedge-slip assembly away from the fluid passageway to its valve open first location.

Abstract: A linear retractable seal valve having an inlet and outlet port and a fluid passageway therebetween with a lateral passageway perpendicular to the fluid passageway and with a wedge sealing-slip assembly slideably held at opposite side edges of the wedge to two guide rails of the valve body and moveable from a distant valve open first location within the lateral passageway to a second location between inlet and outlet ports of the valve. The slip-wedge assembly has at least one closure slip with an inside face of the slip slideably engaging a tapering face of the wedge and with the slip at said second location being restrained from further longitudinal movement and moveable in a perpendicular direction of the longitudinal assembly movement into closure engagement with one of the valve ports. The guide rails are diametrically-opposed and extend longitudinally of the inside face of the lateral passageway into the fluid passageway.

Abstract: 1. A method of making a dual-thrust rocket motor comprising: filling a rocket motor housing with a first propellant grain material, forcing a cured second solid propellant grain centrally within the first propellant grain material and substantially to the bottom thereof, curing the first propellant grain with the second solid propellant grain held in place, and attaching an igniter means and nozzle means to the housing.

Abstract: This patent describes a solid oxidizer for solid rocket propellants comprising small ammonium perchlorate particles containing thereon a coating agent which is applied during the process of grinding larger ammonium perchlorate particles under an inert liquid medium.

Abstract: A method of orienting metal staples randomly dispersed in a solid propellant by filling a bayonet having a screen at the bottom thereof with the uncured solid propellant mixture and forcing the mixture through the bayonet screen.

Abstract: A versatile hand operated loom having features making it uniquely suited for utilization in occupational therapy for hospitalized or institutionalized persons. Simplified hand loom assembly dispensing with the conventional shedding harness enables utilization of simplified procedures in dressing and operating the loom, including weaving of the fabric, removal, and setting up the subsequent weaving operation for the same or a different pattern.

Abstract: This disclosure concerns an explosive device, such as a mine, which comprises a flexible enclosure having a pair of separate chambers formed therein. Substantially non-explosive liquids, which when mixed form a liquid explosive material, are respectively disposed in the chambers in separated relation to each other. A closure member is initially disposed so as to block an opening which provides communication between the chambers. Upon removing a latch mechanism holding the closure member in place,the closure member is moved away from the opening to permit mixing of the non-explosive liquids, thereby forming the liquid explosive material and arming the explosive device. A pressure-responsive igniter mechanism is disposed within the enclosure so as to be subject to the pressure condition of the liquid explosive material.

Abstract: A floating roof for a liquid storage tank has a lid structure comprising a plurality of fluid tight interconnected plates of fluid tight material and a plurality of buoys for imparting buoyancy to the lid structure arranged on the surface of the lid which is opposite the surface of the lid which faces the liquid body upon which the lid floats. Each buoy of at least a majority of the buoys has a base formed of one of said plates, and further includes structure attached to the base and having at least two sides inclined relative to a perpendicular plane through the lid structure and relative to each other.A similar floating roof for a liquid storage tank has again a lid structure and a plurality of buoys on the upper surface thereof.

Abstract: A dough sheet spreader through which dough is extruded in sheets of predetermined width and thickness. A multi-part housing having a downwardly distending, outwardly flaring passageway terminating in an egress, the lips of which are lined with dough release members, is adapted to receive and extrude dough-like material. Provision may be made for degassing the dough during the extrusion process. In one embodiment the thickness of the dough sheet can be varied and in another, both the width and thickness can be varied in progressive, finite steps.
