Abstract: PRECLEANER ASSEMBLY                     ABSTRACT OF THE DISCLOSURE A precleaner assembly for the air intake system of a heavy duty vehicle ejects dust particles and other heavy material from the incoming air stream so that the heavy particles will not clog the normal vehicle air cleaner, thereby greatly increasing its life.  The precleaner assembly includes an inlet which faces the direction of vehicle movement, so ambient air is rammed into the inlet of the precleaner.  The rammed air is directed through turning vanes located in a diverging portion of the assembly to induce a vortex or spiral flow component to the fluid.  Centrifugal force generated by movement of the dust particles in the spiral path causes the latter to be centrifuged radially outwardly with respect to the direction of movement of the flow stream.  These heavy particles therefore are con-centrated in the radial outermost portion of the flow stream, which is ejected from the assembly, so that the remaining portion of the flow stream will be relatively free of the heavy particles.  This remaining portion of the flow stream is then communicated directly to the vehicle air cleaner.

Abstract: ABSTRACT OF THE DISCLOSURE          Synthetic plastic lamp holders for Christmas lights and the like are usually clipped to an eavestrough and holds the cord string of lights at spaced intervals.  They tend to be unsatisfactory because of the lack of stability particu-larly in view of different dimensions and constructions of eavestrough.  This device comprises a holder or hanger which includes a pair of resilient prongs at the rear of a stand-ing part which engages the inside of an eavestrough and are spaced apart.  A pair of resilient jaws extend from the other side of the standing part into which a lamp holder or socket may be clipped.  The spaced apart resilient fin-gers together with the construction of the standing part and associated structure, gives stability regardless of the dimensions of the eavestrough and prevents the wind from moving the lamp holder once installed.

Abstract: WGT-SLW     PHOTOPOLYMERIZABLE AND MOISTURE CURABLE COATING CONTAINING    PARTIALLY CAPPED ISOCYANATE PREPOLYMERS AND ACRYLATE MONOMERS                     Abstract of the Disclosure A liquid radiation and moisture curable 100% reactive coating which cures to yield a clear, tough, glossy abrasion-resistant cured coating is described.  The radiation and moisture curable 100% reactive coating composition comprises:  15 to 60 parts by weight acrylate diluents; and 40 to 85 parts by weight of isocyanate terminated urethane prepolymers formed by reacting a mixture of polyester diols and triols with excess aliphatic diisocyanate to form -NCO terminatd prepolymer and then reacting the -NCO terminated prepolymers with sufficient hydroxy acrylate to cap between about 5% and 15% of the available -NCO sites to form addition polymerizable ethylenically unsaturated sites and a photo-initiator when light is the radiation source.  When the coating is exposed to a source of radiation, the ethylenically unsaturated monomers and prepolymers polymerize to develop a tack-free surface coating, after which the partially reacted coating is further polymerized through the isocyanate terminated prepolymer portion by moisture curing to form the fully cured tough, glossy, abrasion-resistant coating.  The coatings of this invention are particularly well adapted for providing a decorative thermoplastic surface covering with a clear, tough, glossy, abrasion-resistant, light-stable, no wax wear layer.

Title: Method and apparatus for demodulating  signals in a logging while drilling  system
Inventor: WAGGENER WILLIAM N
IPC: E21B47/18
Filed: 1979-02-26
Granted: 1982-06-29
Abstract: ABSTRACT OF THE DISCLOSURE           The disclosure is applicable for use in a logging-while-drilling apparatus for obtaining subsurface measura-ments during drilling in a fluid-filled borehole.  Acoustic carrier waves are generated downhole in the borehole fluid and are PSK modulated in accordance with digital data representative of the measurements.  The PSK modulation is obtained by momentarily unidirectionally either decreasing or increasing the frequency of the acoustic carrier signal until either a desired phase lag (for a decrease in frequency) or phase lead (for an increase in frequency) is imparted to the acoustic carrier signal.  An uphole receiving subsystem includes transducers for converting the modulated acoustic carrier waves to electronic signals and circuitry for de-modulating the electronic signal to recover the measurement information taken downhole.  The uphole circuitry includes an improved carrier tracking loop which is useful, for example, in extracting the carrier from the modulated signal, the extracted carrier then being useful in the demodulation operation.  The carrier tracking loop has a voltage controlled oscillator having a control terminal and a comparator for generating a control signal by comparing the phase of a signal derived from the received PSK modulated signal to the phase of a signal derived from the output of the voltage controlled oscillator.  The control signal is applied to the control terminal of the oscillator. In accordance with an important feature of the invention, the signal applied to the control terminal is compensated as a function of transitions in the received signal to account for the difference between the nominal frequency of the carrier and the average frequency of the received signal. This difference results from the unidirectional nature of the carrier modulation.

Abstract: ABSTRACT OF THE DISCLOSURE         There is provided a method of fabricating a semiconductor device wherein in a bonding surface of a silicon substrate of n-type conductivity are formed recesses having each a bonding surface of a higher order plane index than that of the bonding surface of the silicon substrate, and the substrate and electrodes and the like members are bonded together with an aluminum solder so as to decrease a forward voltage drop FVD.     After forming the recesses but prior to the bonding with the aluminum solder, phosphor is diffused into a region ranging from the bonding surface to a depth of 20 microns, thereby further decreasing the forward voltage drop FVD.  When cooling after the bonding, a temperature gradient is established so that temperature in the silicon substrate is higher than a temperature in the molten aluminum so that the forward voltage drop FVD can be decreased further.

Abstract: FROZEN FRIED FOOD PRODUCT         ABSTRACT This invention relates to a frozen fried food product. Commercially fabricated frozen food products, such as french fried potatoes and the like, are unsatisfactory, because they do not fully duplicate the flavor, taste and texture of a freshly fried french fried potato, and because they tend to blister during frying.  Accordingly, an object of the invention is to provide a frozen fried food product which need not be fried prior to consumption, but which may be prepared for con-sumption merely by heating in a conventional toaster or oven, and which substantially duplicates the taste, flavor and tex-ture of the hot fried product.  The frozen fried food product of the present invention is generally prepared by forming a dough comprised of a farinaceous material, such as cooked, mashed potatoes, and selective amounts of certain additives which are admixed with the farinaceous material to form the dough.  The additives generally comprise water, binding agents, cellulose and dehydrated potato flakes or granules.  The dough is then shaped into the desired configuration of the food pro-duct which is fried in cooking oil to control the water con-tent of said product to a predetermined level, and to absorb a predetermined amount of the cooking oil and to obtain a pre-determined color.  Thereafter, the fried product is frozen and packaged.
