High contrast silhouette images of a substantially opaque object are obtained using front illumination techniques. The object is frontally illuminated by light of a first polarization. A frontal surface of the object reflects the incident light to an observation station. The polarization of incident light bypassing the object and incident on a background is changed. The background light is reflected to the observation station, and the intensity of one of the two, differently polarized, reflected images is substantially reduced with respect to the other. Apparatus for carrying out the method includes a first polarizer for polarizing frontally incident illuminating light, a second polarizer behind the object and a reflective surface behind the second polarizer. A polarization analyzer, located in front of the object, is used to extinguish one of the two reflected images. Apparatus for carrying out the invention in instruments having a polarized light source and a polarization analyzer includes a combination of a polarizing material, for contacting a rear surface of the object, and a reflective surface provided adjacent the rear surface of the polarizing material. The combination is applied to the rear surface of the object. Back-surface mirrors of pleochroic substrates, applied to thin film physical vapor-deposited …

Apparatus is described for detecting flaws in a tubular workpiece in a single scan. The coils of a dual coil bobbin eddy current inspection probe are wound at a 45/sup 0/ angle to the transverse axis of the probe, one coil having an angular position about the axis about 90/sup 0/ relative to the angular position of the other coil, and the angle of intersection of the planes containing the coils being about 60/sup 0/.

Patent for "a bottle-stopper which shall not require any wire, cap or clamp for holding it and which shall by reason of its form and of the materials of which it is composed afford a tight joint or seal under all circumstances." (Lines 13-17) Includes instructions and illustrations.

Patent for a bicycle-holder that holds the bicycle upright. It consists of "a pair of plates clamped upon a portion of the frame of a bicycle, two pairs of ears formed integral with and depending from said plates, one pair of ears being formed convcavo-convex to form a socket between them and constructed with semicircular notches in their lower edges, a rod having a ball or spherical body on its upper end that is located and held for movement in the so formed socket, a lug formed integral with the lower end of one of the remaining pair of ears, and an arm pivoted between said remaining pair of ears, said arm having a bifurcated lower end that engages the rim or tire of the front wheel of the bicycle" (lines 40-54).

Patent for "car-replacers or wrecking-frogs employed for guiding the wheels of a derailed car or locomotive to the rails." (Lines 7-10) Includes instructions and illustrations.

Patent for new and improved animal shears. This design consists in "mechanism for imparting a combined reciprocating and edgewise play to the cutting knife or knives in order to cause the teeth of said knife or knives to follow or describe a curved or oval path, and thus insure greater efficiency of operation; to provide for the proper lateral contact of the knives in order to insure their proper action and to regulate the pressure or force with which one knife bears on the other; [and] to provide a peculiar form of cutter-teeth which shall be automatic or self-cleaning" (lines 19-30).

Patent for "a new and improved car-coupling which is simple and durable in construction and very effective and automatic in operation" (lines 8-11).

This negative ion generator comprises a magnetically insulated transmission line having at least one hole in the cathode to permit negative ions to escape the transmission line, and a device for removing electrons from the negative ion flow.

Adiabatic ion bunching is achieved in a cyclotron axial ion injection system through the incorporation of a radio frequency quadrupole system, which receives ions from an external ion source via an accelerate-decelerate system and a focusing einzel lens system, and which adiabatically bunches and then injects the ions into the median plane of a cyclotron via an electrostatic quadrupole system and an inflection mirror.

In this invention, the efficiency of a two-junction (cascade) tandem photovoltaic device is improved by adjusting (decreasing) the top cell thickness to achieve current matching. An example of the invention was fabricated out of Ga{sub 0.52}In{sub 0.48}P and GaAs. Additional lattice-matched systems to which the invention pertains include Al{sub x}Ga{sub l-x}/GaAs (x=0.3 {minus} 0.4), GaAs/Ge and Ga{sub y}In{sub 1-y}P/Ga{sub y+0.5}In{sub 0.5-{sub Y}} As (O<y<5).

Patent for new invention that would improve in the construction of upright walls.

Patent for an improved liquid fuel burner, one which can destroy the spines of cacti. The burner can also direct fuel in different angles and when ignited will move the flame onto the retort chamber.

Patent for carpenter's tool that has an "adjustable pattern" that can assist in "determining the exact size and configuration of the space in which a stair tread or riser is adapted to be fitted" (lines 9 - 12).
