Abstract: ABSTRACT OF THE DISCLOSURE A louver attachment for lights is constructed so that it is collapsible and portable to permit its use in a variety of applications wherein it is placed over the front of a light source to limit lateral distribution of the light. This configuration is advantageously used in connection with photographer's lighting systems. A framework is provided having two oppositely positioned parallel horizontal members having a series of openings along their lengths. A pair of parallel vertical side members connect corresponding ends of horizontal members together. The interconnections are allowed to pivot so that the parallelogram shaped structure may be collapsed. A wide ribbon is then woven between the horizontal members passing through the openings to form louvers. The ribbon is secured at either end to the framework. Conventional methods of attachment serve to attach the louver attachment over the front of a light source. One form of the louver attachment consists of a pair of rigid ladder-like horizontal members connected together by a pair of rigid, vertical side members. The ribbon is woven between the rungs of the ladder-like members having their respective rungs so spaced as to form parallel and equally spaced louvers.

Abstract: Abstract of the Disclosure This invention relates generally to supports and more particularly to a spring support device for support-ing piping loads subject to generally vertical movement in use due to changes in operating conditions, such as for changes in temperature.  The primary feature of the invention is the utilization of a separable bottom end plate which is mechanically assembled, that is, not inte-grally connected as by welding, to the support casing.          The overall casing including an inwardly extending ring or ledge at the lower end thereof, adapted to hold the separate bottom end plate in assembled condition, can thus not only be disassembled to reuse components thereof, but can be entirely galvanized by hot-dip techniques without the need for weld area touch-up techniques required of prior art construction that integrally weld-assemble the bottom end plate to the casing.

Abstract: Abstract of the Disclosure An improved Schottky barrier connection is made to a desired region of a silicon wafer by implanting the region with ions to peak at æ particular depth; depositing a suitable contact material, such as platinum, over such region; and then heating the wafer to react the platinum and the silicon such that the interface between the platinum-silicide and the silicon penetrates beyond the peak depth of the implant, some of the encountered dopant ions being accumulated at the advancing interface in snowplow fashion. There results a narrowed and concentrated layer of implanted ions localized just below the interface of the silicide and the silicon.  The presence of this layer permits conduction in the forward direction at lower applied voltages without substantially degrading the reverse blocking characteristics.

Abstract: ABSTRACT OF THE DISCLOSURE     Metal powders, metal oxide powders, and mixtures thereof of controlled particle size are provided by reacting an aqueous solution containing dissolved metal values with excess urea.  Upon heating, urea reacts with water from the solution leaving a molten urea solution containing the metal values.  The molten urea solution is heated to above about 180°C whereupon metal values precipitate homogeneously as a powder.  The powder is reduced to metal or calcined to form oxide particles.  One or more metal oxides in a mixture can be selectively reduced to produce metal particles or a mixture of metal and metal oxide particles.

Abstract: Abstract of the Disclosure A spike driving machine is disclosed in which a hole sensing device and spike holder are driven in toward a rail under the action of a fixed stroke piston and cylinder until a stop engages the rail.  The stop has been previously adjusted to line up the hole sensing device and spike holder the correct lateral distance for engagement with the tie plate holes. Excess travel of the piston and cylinder is taken up by providing a flexible connection between an X-frame carrying the hole sensing device, the spike holder and a drive head and a Y-frame which is fixed in the lateral direction. The stroke is chosen to align the spike holder under the drive head.  Thus, the arrangement can be used for rails of differing thickness simply by ad-justing the stop appropriately.

Abstract: ABSTRACT OF THE DISCLOSURE    An analog-signal gate circuit or sample-hold circuit is employed for processing a dot-sequential video signal derived from a solid state imaging device such as CCD imager.  By changing a signal width, gain control operation is achieved, and phase shifting operation of the video signal is done by shifting an aperture center of the dot-sequential video signal.  This system may be applied to a color signal conversion system wherein a dot-sequential color signal is converted directly to an NTSC color television signal.  Further, white balance control for a solid state color television camera is another application of this system.

Abstract: ABSTRACT OF THE DISCLOSURE         A new surface immunoassay method is performed with two test surfaces.  The method is used where serum samples may contain both an antibody for which it is desirable to test, and also competing sera constituents which may be present in indeterminate amounts.  In accordance with the method, two dif-ferent test surfaces are contacted with the same serum sample, and preferably the same aliquot of the serum.  The first sur-face is treated to bind a broad spectrum of serum components including both the component to be tested for and also the com-peting components.  The second surface is designed to bind the competing components but no substantial amount of the serum com-ponent to be tested for.  The immunoassay is conducted with a labeled antibody, and quantitative measurement of the immuno-assay is obtained by detecting the quantitative difference in the amount of labeled antibody on the two surfaces which have been subjected to the same serum sample.  The method has utility in detecting a wide variety of antibodies of both the immuno-globulin G and immunoglobulin M classes, including antibodies for rubella, treponema, herpes simplex virus, cytomegalovirus and toxoplasma.

Abstract: ABSTRACT OF THE DISCLOSURE         A low frequency loudspeaker apparatus includes a folded exponential horn which is divided to provide a bifurcated curved sound path from at least one electroacoustic transducer that is positioned at the throat of the horn to a volume into which sound waves are radiated that is located at the bifurcated mouth of the  horn.  The mean length of the folded exponential horn is such that, at an exponential rate of expansion between the throat and the bifurcated mouth, the area of the mouth is adequate for reproduction of low frequencies in the audible range.  An illustrative embodiment of the low frequency loudspeaker apparatus has an effective low end cut-off frequency of 38 Hz. and affords 99 dB SPL output at three meters with one watt input which corresponds to about 20% efficiency measured in free space.  Presence of a single boundary surface, such as a stage floor adjacent the mouth of the folded exponential horn, improves amplitude response by 3 to 6 dB.
