A plurality of door mounting hooks are provided on the lower edge portion of the trim panel for insertion into mating holes provided on the inner panel so that the trim panel is supported on the door in readiness and alignment for tilting of the trim panel into overlying relationship with the inner panel. A molded plastic guide track is mounted on the door inner panel, and a slider connected with the rod is slidably mounted on the guide track.

Abstract: An adjustable hanger is slightly wider than the vertical vane and includes a horizontal slot through which the vane is pulled as it is installed in the hanger. To shorten the length of the vane between the hanger and the floor, additional vane material is pulled through the slot. The excess material that has been pulled through the slot hangs down on the opposite side of the vane and is invisible from the front of the blind. Each vane has its own adjustable hanger and can be adjusted individually.

Abstract: The invention is for a cord system for a dual function window blind. A looped cord acting with a master carrier controls the traversing movement of the vertical vanes. The other, smaller diameter cord controls the tilt of the vanes and is not a looped cord but a much thinner cord with a tassel attached at each end. The tilting is performed by pulling the tassels whereas the traverse is performed by pulling the heavier cord. The first, looped cord slides freely through holes in the tassels. The result is the appearance of a single cord with a tassel on each side.

Abstract: An inexpensive but easily operable window shade, as for use in a recreational vehicle. A substantially rigid mounting bar has fabric comprising a shade hanging a desired distance from one side thereof and a valance hanging a lesser distance from the other side thereof. The fabric may, for example, be woven wood. Interengageable means, such as snap buttons or "Velcro", are affixed to said valance and to the shade for separably securing them together when said shade is in a desired raised position.

Abstract: There is described an improvement for an apparatus employing a plurality of operational elements adapted to cooperate for producing an electrical signal representing the variation of an ordinate quantity with respect to an abscissa quantity changing at a controlled rate. At least one of said elements requires an adjustment during operation such as is capable of causing spurious transients in the electrical signal. The apparatus further comprises a filter for filtering the electrical signal before feeding the signal to a suitable utilization device such as a recorder. The improvement includes control means which operate to interrupt the ordinate quantity signal and cut off the filter response prior to any element adjustment. There is disclosed means for storing the output of the filter at cut off and for memorizing the point along the impulse characteristic of the filter at which cut off takes place.

Abstract: A tunable electrical filter is disclosed wherein an RC (resistor-capacitor) network comprising a plurality of switchable capacitors among the components determining the time constant of the filter provides a given minimum value of filter time constant and, therefore, a given minimum bandwidth, when all the capacitors are continuously connected in the network. Each capacitor is coupled to the network through the output means of an electronic switching means. A pulse generator connected to the input means of said switching means provides a train of pulses having an adjustable ON-time to OFF-time ratio. When all the capacitors are periodically switched by the output of the pulse generator, the effective filter time constant increases from said given minimum value as the ON-time compared with the OFF-time decreases. The pulse generator is provided with control means for adjusting the ON-time to OFF-time ratio.

Abstract: A double-beam, time-sharing, ratio-recording spectrophotometer in which the reference signal data is evaluated both in an actual demodulation cycle and in a different cycle, which may be either a preceding or a following cycle. The two evaluations are combined to produce derived reference signal data. Ratioing means are included for extracting the ratio between the sample signal data evaluated in an actual demodulation cycle and the derived reference signal data. Predetermined multiplying factors may be used in arriving at the derived reference signal data. The interpolation of reference signal data from actual and non-actual demodulation cycles enables the effect of uncompensation on photometric accuracy to be minimized. Uncompensation results from the fact that in a time-sharing spectrophotometer sample and reference signal data do not occur at the same time and do not therefore relate to the same environment and the same wavelength.

Abstract: A stabilizer for use with a string of single tube or dual concentric drill pipe above a bit having analogous tubular members adapted for fluid tight interconnection with the pipes of said string to provide a conduit for drilling fluid. A stabilizer means encircles the stabilizer body and is adapted to contact the hole wall. The stabilizer means includes a sleeve bearing mounted to rotate with respect to the stabilizer body and a stabilizer sleeve mounted stationary on the sleeve bearing. A port means in the stabilizer body provides fluid communication between the drilling fluid conduit and the stabilizer sleeve and/or thrust bearing. An exit port means in the lower end of the stabilizer means provides fluid communication between the stabilizer sleeve bearing and the outside of the stabilizer.

Abstract: A bit packer for use with a string of dual concentric drill pipe, having inner and outer tubular members concentrically arranged to mate with the inner and outer pipes of the drill string to provide an annular conduit for fluid from surface to bit and a central conduit for fluid and cuttings from bit to surface, is particularly characterized by flexible packing means mounted slidably and rotatably on the outer tubular member. The packing means deform against the hole wall to seal the annular space between the outer member and the hole wall. Upper and lower ports provide fluid communication between the annular conduit and the annular space; when the packer is moved downwardly in the hole the packing means slides upwardly to close the upper port and open the lower port; when the packer is moved upwardly in the hole, the converse occurs. A milling collar is provided above the packing means.

Abstract: Disclosed is a fluorescence spectrometer having an intermittently activated sample irradiating source, such as a UV lamp, the periods of activation being short (e.g., 100 microseconds) in comparison to the intervening inactive periods (e.g., 20 milliseconds). Fluorescence radiation emitted by the sample is detected by a photomultiplier, the output signal of which is supplied to an integrating amplifier for utilization. A field effect transistor (FET) in the output circuit of the photomultiplier has its gate coupled to a control unit which determines the activation periods of the lamp and, in timed relation thereto, cuts off the FET to interrupt the output circuit during periods that the lamp is inactive. A dual channel fluorescence spectrometer is also described.

Abstract: A system for developing or cleaning a screened well using dual concentric drill pipe. A blind annulus injection sub and a development head are interconnected with the drill pipe and so constructed that compressed air passing down the inner pipe is directed through nozzles in the head to agitate formation water and clear the screen. When air is passed down the pipe annulus it is injected into the inner pipe and causes formation water and sand to be drawn into the head and airlifted to the surface through the inner pipe.

Abstract: A crucible for melting a nickel-based superalloy containing one or more of the elements aluminium, titanium and hafnium is made of magnesia grains bonded by tinania, hafnia or yttria. The purity of the magnesia is not less than 97%.

Abstract: An injection sub for use with a string of dual concentric drill pipe, having inner and outer tubular members concentrically arranged to mate with the inner and outer pipes of the drill string to provide continuous isolated annular and central passageways, is particularly characterized by an annular chamber in the inner member. Ports permit the flow of fluid from the annular passageway to the chamber, and apertures permit fluid flow from the chamber to the central passageway. An annular check valve in the chamber cooperates with the ports to prevent flow from the chamber to the annular passageway.
