Abstract: A fluorescence sensing device for determining the presence or concentration of an analyte in a liquid or gaseous medium is constructed of a fiber optic plate comprising optical fibers having relatively small numerical apertures. The fiber optic plate is positioned on a photodetector and has a layer of analyte permeable fluorescent matrix or coated waveguide material on its top surface. The fluorescent matrix or waveguide coating contains indicator molecules whose fluorescence is affected by the local presence of analyte. A light source emits light into the fluorescent matrix in a direction generally parallel to the top surface of the fiber optic plate. Upon absorbing light from the light source, indicator molecules in the fluorescent matrix emit fluorescent light which is transmitted through the fiber optic plate to the photodetector.

Abstract: A nuclear fuel rod assembly support structure has top and bottom end pieces, and a plurality of fuel rod spacer grids and control-rod guide tubes having top and bottom ends respectively fastened to the top and bottom end pieces to hold these pieces interspaced, the guide tubes being inserted slidably through the openings in the spacer grids and the latter being positioned between the end pieces of the support structure. It is necessary to fix the spacer grids to the guide tubes to maintain the spacer grids at properly interspaced positions and to provide a support structure that is as rigid as possible. For reasons of nuclear physics, the guide tubes and spacer grids are made of different metals or alloys which are difficult to fix together by the use of solidified molten metal using presently known welding and soldering techniques. To overcome this problem, sleeves are used through which the guide tubes are inserted with the spacer grids positioned between these sleeves and with the sleeves axially engaging th spacer grids, the sleeves being fixed to the guide tubes by the solidified molten metal. This overcomes the problem because the sleeves and the guide tubes may be made of the same metals or alloys which can be welded or soldered together easily.

Abstract: A method for contactless measurement of conductivity and/or temperature on metals by means of the eddy current effect induced within the metal by an alternating magnetic field produced by an excitation coil fed with alternating current arranged with its axis perpendicular to the surface of the metallic test specimen, there being in addition to the excitation coil a pair of measuring coils of equal radius arranged coaxially and symmetrically with respect to the excitation coil at each end respectively of the excitation coil and having an axial length substantially less than that of the excitation coil. The two measuring coils are connected electrically in series opposition and the phase angle between the current in the measuring coils and the current in the excitation coil is taken as an indication of the measured variable. In order to reduce the so-called "lift-off" effect to a minimum and allow accurate contactless measurement such that substantial tolerances are permissible for the distance between the test specimen and measuring head which carries the coils, the radius between the excitation coil on the one hand, and the measuring coils on the other, is smaller than 1/4 or greater than 4, depending on whether the measuring coils are located respectively outside or inside the excitation coil, and the measuring head is at such a distance from the specimen surface that the phase angle between the excitation-coil signal and the measuring-coil signal exhibits a maximum.

Abstract: An integral power steering assembly of the type which includes a housing defining a power cavity with a rack-toothed piston movably supported in the cavity and in meshing engagement with a sectored gear which in turn rotates an output shaft. A control valve is supported by the housing for controlling the flow of pressurized fluid from a source to the cavity on one side or another of the piston and the return flow from the opposite side of the piston whereby the piston is moved in alternative and opposite directions. An input shaft forms a part of and controls the control valve. Mechanical connections also interconnect the input shaft and an output shaft for rotating the output shaft in response to rotation of the input shaft in the event of the lack or loss of fluid pressure to move the piston hydraulically. These components are in the form of an integral or unitized package which may be attached to a vehicle as one unit. The improvement comprises a bleed valve establishing communication between the power cavity in which the piston is disposed and the return line from the control valve for automatically bleeding air from the hydraulic power cavity in which the piston is disposed. The bleed valve includes a valve member slidably disposed in a passage and normally held away from a valve seat by a spring. The valve member allows air to pass thereby but as the hydraulic fluid pressure increases, the valve member will be moved against the seat to prevent the flow of hyraulic fluid from the power cavity to the return.

Abstract: This invention provides a method and apparatus for use with the rolling of hot metal strip. The first step in the rolling of hot metal strip is to roll a transfer bar of about one inch thickness, and this is ordinarily then passed through a series of finishing mills which reduce the thickness of the transfer bar to the desired final stage. The method and apparatus of this invention provides for the coiling up of a transfer bar after it has been rolled but before it passes to the finishing mill, the transfer of the coiled transfer bar from the coiling location to an adjacent uncoiling location where uncoiling can be completed or completely carried out, and initiating the coiling of a further transfer bar while the first transfer bar is still uncoiling.

Abstract: 1515720 Automatic exchange systems WESTERN ELECTRIC CO Inc 6 Nov 1975 [7 Nov 1974 (2)] 46015/75 Heading H4K A ring trip arrangement common to a group of lines each of which receives ringing current during a different phase, comprises a loop current detector that is selectively connected to one line at a time during the ringing phase thereof. Preferably all the lines are arranged in groups each with a common loop detector, and a common ringing generator is connected to each detector so as to apply current therethrough to more than one line during each phase (Fig. 1 not shown). The arrangement is for use in a TDM system where high voltage ringing must be applied at the line circuits rather than via the network. Fig. 3 depicts the arrangement for a single group. A not shown control system marks wires BPS, BBS of a called line and at the start of each ringing phase (there being 4 phases, each of 1 sec on 3 secs off) also marks BRBS, BRBC such that flip flop RFF sets to turn-on relay RINGO. The latter connects ringing current from generator RG via common detector D1 to the ring lead R of the called line TS1. At the end of the phase, wires BRBS, BRBC are marked such as to reset RFF and thus drop RINGO. During the "silent" portions of ringing, line relay LCO monitors the line for an answer signal and repeats the answer via gate SS to control (SS is prepared by the called line marking on BPS, BBS and the reset condition of RFF). If the subscriber replies during a ringing phase, detector D1 causes RFF to immediately reset, thus dropping RINGO and thereby permitting LCO to rise with results as before.

Abstract: Basic zirconium gels may be used to form complexes with conventional aluminum and/or zirconium antiperspirant systems. The freshly prepared basic zirconium gels provide both a buffer for the highly acidic aluminum-zirconium complexes and an additional source of zirconium as an active ingredient in the antiperspirant. The preferred basic zirconium gels are basic zirconium-amino acid compounds, particularly basic zirconium glycinates, and the compounds are preferably added to aluminum-zirconium systems in the form of a wet gel. The preferred basic zirconium glycinate is formed by first reacting sodium carbonate with glycine, and then reacting the resulting sodium glycinate with a zirconium oxy or zirconium hydroxy compound to precipitate out the zirconium basic glycinate gel. The various complexes of the invention may be used in conventional antiperspirant forms, including aqueous solutions, aerosol sprays, powder-in-oil aerosol sprays, creams, lotions, cream sticks, etc.

Abstract: A seal unit for movement through a flow conductor for pumpdown piston or well swab service, including a mandrel body, a seal element mounting sleeve disposed for limited travel on the body, and elastic annular seal means secured on the mounting sleeve to seal with the flow conductor wall in response to a first fluid differential across the unit and to permit controlled bypass and load transfer under a second higher differential. The seal means includes spaced annular lips or fins and an annular choke ring which is expanded by limited sleeve movement in response to a fluid pressure differential load applied across the fins. When the pressure differential across the fins exceeds a predetermined value, the sleeve expands the choke ring which assumes a major portion of the pressure differential load relieving the fins to reduce fin wear. As a pumpdown piston, the unit is pumped along a flow conductor to drive a tool train by fluid flow in a direction from the fins toward the choke ring. As a swab, the unit is pulled in the opposite direction to agitate or displace fluid in a well.

Abstract: A method is disclosed for making a metallic body having desirable magnetic properties. The metallic body is made from an alloy which contains Fe, Cr, and Co and which may also contain one or several additional ferrite forming elements such as, e.g., Zr, Mo, V, Nb, Ta, Ti, Al, Si, or W. According to the disclosed method the alloy is cooled at a rate of at least 60 degrees C. per hour from an initial temperature at which the alloy is in an essentially single phase alpha state to a second temperature which is in a vicinity of 600 degrees C. Subsequently, the alloy is cooled at a second, slower rate to a third temperature which is in the vicinity of 525 degrees C. The disclosed method allows for a relatively broad range of initial temperatures, is relatively insensitive to compositional variations of the alloy, and permits simple reclamation of suboptimally treated parts. As a consequence, the method is particularly suited for large scale industrial production of permanent magnets as may be used, e.g., in relays, ringers, and electro-acoustic transducers.

Abstract: A Central Processing Unit (CPU) includes a hardware op-code extending register (OER) for storing a code for programmable selection of optional CPU features which modify processor operations defined by the op-code in each instruction. A control section in the CPU decodes both the op-code of a current instruction and the code in the OER, effectively combining the two to form an extended op-code capable of defining a larger set of processor operations than the op-code carried in each instruction. The code in the OER is changed only when the CPU executes an instruction for transferring a new code into OER. Thus the code in OER can remain stationary over many instruction cycles.
