Abstract: METHOD AND APPARATUS FOR DETECTING, RECORDING AND USING SCENE INFORMATION      IN A PHOTOGRAPHIC SYSTEM             ABSTRACT A method of operating a photographic camera to record data in correspondence with a picture frame includes activating a flash to provide illumination for exposing the picture frame onto a photographic film.  Sensing is performed to determine if light generated by the flash is reflected from a subject in the picture frame.  Data is recorded in association with the picture frame indicating if reflected light is sensed.  In accordance with a method of operating a photographic printer to print a negative frame, the reflected flash illumination data associated with the negative frame is read.  An appropriate exposure for the negative frame is selected based at least in part on the presence or absence of the sensed reflected flash illumination.

Abstract: Abstract 1.   Flow-through heater. 2.1  A flow-through heater is arranged between a deliver system and a spray system and incorporates at least one channel in which the materials, preferably paints, are heated by means of a heating system.  The flow-through heater must be simply constructed, easy to clean, and economical to produce. 2.2  According to the present invention, the channel (1) is formed in a first structural element (2) that can be secured to a second main structural element (3) that incorporates the heating system (4). 2.3  The flow-through heater according to the present invention permits the simple and rapid changeover of the structural element that incorporates the channel; this structural element can be so constructed as to be simple and robust.          This means that the flow-through heater can be used for handling materials, in particular paints.     Figure 1.

Title: Hybrid stochastic gradient for convergence of adaptive filters
Inventor: BATRUNI ROY G
IPC: H03H17/02

Granted: 1993-05-25
Abstract: ABSTRACT      The present invention provides a technique for updating the coefficients a(n) of an adaptive filter impulse response A(n), where A'(n) = (a0(n) a1(n) . . . am(n)) is the adaptive filter impulse response at time n.  The impulse response is utilized for tracking the output y(n) of a communications channel, where y(n) =   where H is an unknown impulse response of the channel, H' = (h0 h1 . . . hm), the ' character denoting transposition.  The channel is driven with a known input signal S(n), where S'(n) = (s(n) s(n-1) . . . s(n-m)).      According to the technique, the output x(n) of an adaptive filter, where x(n) = S'(n) A(n) is compared with the channel output y(n) according to the Least Mean Squares (LMS) algorithm to develop an LMS error prediction signal.  At the same time, the adaptive filter output x(n) is compared with the channel output y(n) according to the Sign Algorithm (SA) to develop an SA error prediction signal.  If the LMS error signal is greater than or equal to a preselected value, then it is used to update the coefficients a (n) of the adaptive filter impulse response.  If the LMS error signal is less than the preselected value, then the SA error signal is used to update the coefficients a(n).

Abstract: FIRE BARRIER FABRIC      Abstract A fire-resistant fabric suitable for use as a flame barrier comprising a flame durable textile fabric substrate formed of corespun yarns, the yarns comprising a core of flame resistant filament and a sheath of staple fibers, and an intumescent coating carried by one surface of the textile fabric substrate.  In normal use, the fabric is flexible and conformable and has good air porosity.  When exposed to high temperature and/or a flame, however, the intumescent coating reacts and swells to form a char which closes the pores or interstices of the fabric to thus prevent flame or hot gases from penetrating therethrough.

Abstract: Abstract of the Invention An optical fiber splice and the method of forming it are described wherein a hollow cylindrical glass member is provided, the member having a bore along the longitudinal  axis  thereof.  Fluid  at  a pressure  in excess of ambient pressure  is  provided to the bore while the member is subjected to localized heating of the member to the softening point of the glass.  In this manner, a bubble is formed within the member bore under the influence of said heating and pressure.  For more uniform bubbles, the member may be rotated about its  longitudinal axis while it  is subjected to said fluid  pressure  and  heating.   The  splice  member  is subsequently formed by severing the cylindrical member at the location of the bubbles.  Optical fibers may be inserted  into  the  ends  of  the  splicing member  and cemented in place.

Abstract: @ Foraminous members (19) useful in making paper webs. The faraminous member of this invention has a macroscopically monplanar, patterned, continuous network surface (23) which serves to define within the member a plurality of discrete, isolated, deflection conduits (22). A foraminous woven element (43), such as a screen, is thoroughly coated with liquid photosensitive resin to a controlled depth above the upper surface of the woven element. A mask or a negative having opaque and transparent regions which define the pattern is brought into contact with the surface of the liquid photosensitive resin and the resin is exposed to light of an activating wavelength through the mask. The resin exposed to the activating light is hardened (cured). Uncured resin is removed from the composite leaving behind the woven element with the solid network formed by the cured resin.

Abstract: A rock bolt is manufactured from a steel tube which has been deformed to have a deep depression so that it assumes a substantially reduced diameter. A sleeve is pressed onto the outer end thereof which is sealed through welding. An installation chuck carried on an installation rod comprises a socket for receiving the outer sleeve and when the rock bolt has been manually inserted in a borehole, for example by means of the chuck, high pressure liquid is conveyed through passages in the chuck to a hole which leads through the sleeve to an interior chamber of the tube so that the tube expands through plastic deformation, thereby anchoring the rock bolt in the borehole. The chuck is then relieved of pressure and removed from the anchored rock bolt.

Abstract: In local area networks (LAN's) which are required to operate in duplex mode it is necessary for the common communication medium to be operated in a t.d.m. manner. Because the LAN has no common equipment, every station is arranged to contain its own control circuitry and crystal controlled clocking system to produce time slot markers. The system is organised so that each time slot comprises an active period for data or speech transmission or contention resolution, followed by a transit period in which the data or speech reaches the destination. Ideally time slot markers occur simultaneously in both stations and for intermediate stations there is a tolerance which reaches a maximum at the midway point of the network communication medium. The multiplexing system arranges that the time slots are packed as closely together as the delay between most separated stations will allow. The near simultaneous occurrance of time slot markers is maintained by all stations whether busy or free by observing the timing of traffic on the communication medium and adjusting the timing of the station time slot marker to occur in the time between data or speech bursts of existing traffic.

Abstract: A method for selectively closing pores in a formation's zone of greater permeability.  A rehealable Xanthan or Alcaligenes biopolymer in an aqueous medium is combined with an organic or transition metal cross-linker which forms a first stage selective ex-situ gel.  Second stage non-selective gel precursors are also included.  The second stage gel comprises a polymer cross-linked with organic cross-linkers so as to form an in-situ gel more able to withstand formation conditions.  The combination is injected into a formation after the first stage gel forms where it selectively enters a zone of greater permeability carrying therewith said non-selective gel.  Once in the formation's zone of greater permeability, the gel reheals and forms a rigid gel having the desirable characteristics of the non-selective gel.
