Abstract: ABSTRACT OF THE DISCLOSURE           A fastener for use in load carrying harness or the like is provided with a plate from which protrude stem means adapted to pass through a utility carrier and through a strap, with a securing plate arranged to be attached to the protruding end of the stem means, to thus secure a carrier attachment to a waist belt or the like.          The fastener and the overall assembly is more convenient to use as it prevents the carrier pouches or the like to slip along the belt or strap.  Also, the load carriers are prevented from pivoting about the carrier belt, to add to the comfort of the person carrying the harness. The fastener is of a relatively simple structure and has wide use at different points of the harness both for securing the load carrier attachments to the harness and for securing part of the harness straps to each other.

Abstract: BOILER CONTROL PROVIDING IMPROVED    OPERATION WITH FUELS HAVING   VARIABLE HEATING VALUES     ABSTRACT OF THE DISCLOSURE         A boiler control regulates the input fuel and air to satisfy load demand.  Simultaneously, the air flow is adjusted by an air flow control to correct for changes in fuel heating value by means of a circuit which operates in response to outlet steam flow and input mass fuel flow to determine the difference in presumed heat input and actual heat output and, by inference from the heat imbalance or error, a change in fuel heating value.  The heat error is used to adjust the air flow demand to the air flow control.          In another embodiment, boiler heat pickup is derived to remove from the heat imbalance any heat input changes other than fuel heating value changes.

Abstract: ABSTRACT             Retroreflective sheeting is taught which incorpo-rates markings that are distinctly visible when the sheet-ing is viewed at an angle under retroreflective viewing conditions, thereby allowing a viewer to determine the identity of the sheeting.  The sheeting comprises a mono-layer of microsphere-lenses; a spacing layer coated on the microsphere-lenses and contoured so as to generally follow the curved back surfaces of the microsphere-lenses; a specularly reflective layer coated over the spacing layer; and a transparent image layer disposed in an imagewise pattern between the spacing layer and specularly reflective layer, with the thickness of the image layer being greater in the valleys of the spacing layer between the microsphere-lenses than on the curved surfaces directly in back of the microsphere-lenses.

Title: Optical communication cable

IPC: G02B6/10
Filed: 1977-11-28
Granted: 1982-02-16
Abstract: A B S T R A C T            In an optical communication cable for the transmission of light, two or more optical fibres are secured side by side on or within a flat flexible support member which is so housed that it is capable of limited movement relative to the cable when the cable is flexed, thereby reducing risk of fracture of any optical fibre.  The flexible support member is loosely housed in, and has dimensions less than the diameter of, a bore in an extruded elongate body of insulating material, which bore has a smooth continuous boundary wall and is of uniform transverse cross-section throughout its length.  To provide reinforcement for the cable, two separate elongate reinforcing members are embedded in the extruded body throughout its length and are arranged on opposite sides of and parallel to the bore.          As compared with optical communication cables hitherto proposed, the optical cable is simple and inexpensive and because limited movement of the flexible support member -and hence of each optical fibre - can take place within the cable, there is substantially less risk of fracture of or damage to any optical fibre during manufacture and installation of the cable.

Abstract: IMPROVEMENTS IN THE MANUFACTURE OF GLASS WHEREIN HOT METAL MOLDS ARE PROVIDED WITH A SOLID FILM LUBRICANT LAYER     ABSTRACT OF THE DISCLOSURE            An improvement is provided in methods for forming glass articles which methods are of the type wherein hot formable glass is first formed into a parison, or blank, in a parison or a blank mold and then the parison, or blank, is formed into the final glass article in a blow mold and wherein there is no relative rotation of the glass and the respective molds in the forming operation; the improvement resides in providing the cavity-defin-ing surface of the blank mold with a layer, or coating, of a solid film lubricant or glass release agent which essentially comprises a non-colloidal lubricating graphite dispersed in a thermoset, cured, hard organopolysiloxane binder.  The layer, or coating, is formed by applying a dispersion of graphite in an organic solvent solution of a further-curable, thermosettable, solvent soluble, organopolysiloxane onto the cavity defining surface of the blank mold and the curing said organopolysiloxane to a thermoset hard condition.  In another embodiment of this invention, the blank mold and the blow mold will both carry such a layer, or coating, but the blow mold will have a layer in which the graphite particle size is no larger than the size of the graphite employed in the blank mold layer and, preferably, will be smaller than the size of the graphite employed in the blank mold layer.

Abstract: ABSTRACT OF THE DISCLOSURE      A thrust bearing assembly for positioning and maintain-ing both washers of a spherical roller thrust bearing in alignment with a rotatable shaft that is supported by the bearing.  The assembly is characterized by including a reciprocally movable chair member for seating the housing washer of the spherical roller thrust bearing in a manner that prevents the washer from being unduly tilted relative to its axis of rotation when the chair member slides axially relative to the shaft.  A back portion of the chair member is made to exceed the height of the housing washer by a predetermined amount such that the relationship of its height to the overall diameter of the chair member is a desired ratio relative to the radial clearance of the chair member with its supporting housing.  This relation-ship of the components prevents the housing washer and chair member from tilting more than an established tolerance angle relative to the axis of rotation of the shaft.

Abstract: Abstract of the Disclosure A dynamic sense-refresh detector amplifier consists essentially of a cross coupled MOS transistor pair and two sets of load-refresh circuits which each include a capacitor and three MOS transistors.  The load-refresh circuits eliminate the negative effect of threshold voltage losses on noise margin by allowing the memory cells from which information is read out and sensed to be refreshed to full 1 and 0 levels.  A control terminal of a transistor of each load-refresh circuit is coupled to the transistor of cross coupled pair not associated with that load-refresh circuit.  In addition, a voltage clamping transistor is used with each load device to further increase operating noise margins.  The dynamic operation of the amplifier allows for relatively low power dissipation.
