Abstract: ABSTRACT          The volume of atmosphere needed to inhibit  the ingress of ambient oxygen into the furnace chamber (3) of a continuous heat treatment furnace (1) can be reduced by introducing a gas containing free oxygen (e.g. air)  into the entrance section (2) and/or exit section (4) adjacent the roof thereof. Thus a relatively inexpensive  gas  may often be used in combination with an expensive atmosphere thereby  significantly  reducing  overall  process  cost.          Continuous  heat  treatment  furnaces  can   readily   be converted to  perform  the  method  by  simply  inserting adjacent the roof of the entrance and/or exit  section  a tube (3) having a slot and/or a plurality  of  downwardly facing holes (9) and connecting the tube to a  supply  of the requisite gas. The invention is  applicable  to  both double open ended furnaces  and  continuous  furnaces  in which the exit section is filled with a liquid, e.g.  oil or  molten  salt.  In  these  latter  cases  the  gas  is introduced in the entrance section (2).

Abstract: LOW PRESSURE HIGH TEMPERATURE SAFETY VALVE                 Abstract of the Disclosure A safety valve for relief of overpressure from a relatively low pressure high temperature fluid system with which the valve is intended to be operative.  System pressure is communicated via a body inlet leading to the underside of a displaceable closure disc that cooperates with an annular seat for opening and closing the valve to fluid flow.  A predetermined loading force is applied against the topside of the disc urging it toward closed position in opposition to fluid pressure thereat.  To minimize or eliminate adverse temperature effects on the disc loading force at the set point operation of the valve, the closure force imposed against the disc is divided between a coaxially supported mass of predetermined weight and a compressed coil spring operative in series relation therewith.

Abstract: ABSTRACT   TELEVISION SYSTEMS AND SUBSYSTEMS THEREFOR     An image is scanned by a color camera (800-808) and the luminance representative signals (e.g. Green) of pairs of adjacent lines are summed and differenced in a processor 861.  Color signals R,G,B and the sum signal (GS) are matrixed to form chrominance components and luminance components  of a standard composite video signal (e.g. I,Q, YS for NTSC) in a matrix 812.  One of the chrominance components (I) is comb filtered (1112) to remove portions of its frequency spectrum. The difference signal ( G .DELTA. ) is comb filtered (1122) to be inserted (1124) into the removed portions of the chrominance component (Fig 11).          A receiver (Fig 9) of such a composite signal comprises an adder (934) and a subtractor (935) together with a weighting circuit (935) for summing and differing the summed and differenced signals to reproduce the original luminance signals, which are then displayed on a display (921). In a compatible high definition system first ones (L1, L2) of the pairs of lines conform to a standard TV system (e.g. NTSC) and the second ones (L1A, L2A) are offset by e.g. ? of the standard interline spacing. In an example of the high definition system, the pairs of lines are sampled by a sinusoidal scanning path the samples from the lines being derived by a synchronous switch (618) (Fig. 6).          The difference signal (G .DELTA. ) is invisible on a conventional receiver but allows high vertical defintion on the receiver of the invention.

Abstract: METHODS OF AND APPARATUS FOR VAPOR DELIVERY  CONTROL IN OPTICAL PREFORM MANUFACTURE            Abstract A vapor delivery system for the manufacture of an optical preform includes a deposition bubbler and another bubbler referred to as a supply bubbler which is interposed between a reservoir of a liquid and the deposition bubbler. Heat energy is applied to the supply bubbler and to the deposition bubbler to vaporize liquid therein.  A carrier gas is introduced into the liquid in the supply bubbler at a location below the free surface and into the deposition bubbler to cause vapor to the liquid to become entrained in the carrier gas and to flow from the supply bubbler into the deposition bubbler and from the deposition bubbler to a substrate tube from which an optical preform is made. Facilities are provided for maintaining sufficient liquid in the supply bubbler and suitable temperatures of the liquid in the supply and deposition bubblers to control the vapor flow into and out of the deposition bubbler to prevent unintended perturbations in the deposition bubbler. As a result, the concentration level of the vapor which is entrained in the carrier gas and delivered to the substrate tube is maintained at a substantially constant value.
