Abstract: Abstract The apparatus includes two tools for forming holes in the subsoil without oxcavating it, which tools being coaxially mounted on a drill column. To the end of the drill column there is attached a hollow tool which is concealed when a skirt is in a lower position and exposed when the skirt is in an upper position. A soil displacing body is mounted on the drill column and above the tool. The soil displacing body is a hollow structure and has an upper opening wherethrough its inner space communicates with a concrete feeding tube and a lower opening closable by the skirt in its upper position. To construct a tubular pile the apparatus is driven into the subsoil whereby a design hole is formed, then the apparatus is withdrawn from the hole with a simultaneous filling of the hole with a concrete mix through the concrete feeding tube, the soil displacing body, and the lower opening provided there-in. A ballasting material is concurrently fed through the drill column, out of the hollow tool, and into the space defined by the skirt, which, as the apparatus is being withdrawn, assumes a lower position to conceal the hollow tool and define a hollow in the concrete that has been laid in the tube.      The invention is useful in constructing cast in place tubular piles in loose and water-saturated soils.

Abstract: METHOD OF TREATING FERROUS METAL                 ABSTRACT OF THE DISCLOSURE      A method of treating ferrous metal includes the steps of containing in a metallurgical vessel a quantity of ferrous metal which is at least partially solid in form, entraining  finely divided carbon and a fluxing agent in a nonoxidizing gas and injecting the same in a first flow path and from beneath said metal, simultaneously injecting a first quantity of oxygen in a second flow path separate from said first flow path and beneath said metal for oxidizing the carbon to elevate the temperature of said metal.  A second quantity of oxygen is injected into the metal in a third flow path and from above the metal for reducing the carbon content thereof.  Additional fluxing agents may also be introduced from above the metal.  After the desired metal tempera-ture has been achieved, the delivery of carbon and fluxing agents through the first flow path is terminated while the flow of nonoxidizing gas is continued to promote mixing.  The delivery of oxygen through the second and third flow paths is continued until the level of carbon in the metal has been reduced to a predeter-mined level.

Abstract: THERMALLY CONTROLLED VENT DAMPER              ABSTRACT OF THE DISCLOSURE    A thermally operated vent damper wherein a flue pipe (12) mounts an eliptical damper plate (38) for rotation about a hollow rod 130).  A slot (42) is formed in the damper plate (38) by bending a flange (44) perpendicular to the plane of the damper plate (38) and providing an opening for a coil (52) of bimetal-lic material.  The coil (52) controls the movement of the damper plate between closed and opened positions responsive to temperature in the flue pipe (12).  An opening (19) in the flue pipe adjacent to the coil (52) provides a means for maintaining the coil (52) tempera-ture lower than the flue gas temperature and for control-ling the opening of the damper plate in the flue pipe in inverse proportion to the draft therein.  A second bimetallic coil (60) is mounted outside the flue pipe to relieve stresses on the first bimetallic coil during prolonged high temperature excursions within the flue pipe.

Abstract: SELF-COMPENSATING HYDROSTATIC FLATTENING OF SEMICONDUCTOR SUBSTRATES            ABSTRACT      A semiconductive substrate (1), such as a silicon wafer, is mounted on a baseplate (3), for inclusion in an optical device such as a liquid crystal light valve. An optical flat (9) presses the top surface of the silicon wafer toward the baseplate and against a ring seal (5) surrounding a fluid adhesive (7).  The fluid adhesive hydrostatically distributes the force of compression to guarantee optical flatness and self-compensation for the amount fluid adhesive surrounded by the O-ring.  The optical flatness of the semiconductor substrate is limited only by the flatness of the optical flat against which it is compressed.  Parallel alignment of the optical flat (9), the substrate (1) and the baseplate (3) is achieved by reflecting a laser beam (20) through the semiconductive substrate and observing the interference fringes therein, while adjusting the relative alignment so as to maximize the distance between fringes.

Abstract: TITLE          Foldable Peep Sight ABSTRACT OF THE DISCLOSURE         A foldable peep sight according to the teachings of the present invention is shown for use with a firearm such as a rifle.  A peep sighting member is mounted on an arm.  The arm is pivotally mounted about a horizontal axis which is generally parallel to but spaced from the gun barrel by an arcuately shaped mount.  The arm is pivotal between a first, non-sighting, transport, storage position adjacent the gun barrel and a second, sighting position spaced from the gun barrel and in firing alignment with the front sight of the firearm to allow aiming of the firearm by aligning the firearm to have the peep sight and the front sight of the firearm in line with the target.  A spring located between a spring block attached to the mount and a leg attached to the arm biases the arm to its second, sighting position.  The peep sighting member can be aligned by elongated slots through which screws extend for mounting the peep sighting member on the arm and by an abutment member which controls the angle the arm moves into its second, sighting position.  In the preferred embodiment, the firearm further includes a pivotally mounted scope sight which is pivotal from a first, sighting position and a second, non-sighting position.  When the scope sight is in its first, sighting position, the scope sight abuts with and moves the arm to its first, non-sighting position and when the scope sight is located in its second, non-sighting position, the scope sight does not abut with the arm of the foldable peep sight which then moves under the bias of the spring to its second, sighting position.

Abstract: ABSTRACT:           A low insertion loss surface acoustic wave filter in which withdrawal weighted launching and output trans-ducers 20, 40 are acoustically coupled by two high effici-ency reflective multistrip couplers 6, 6'.  To reduce the insertion loss, the inner bus bars 21, 41 are reduced in width so as to reduce the dead space 12 in the coupler.          This makes it impossible to form a reliable wire bond con-nection to the inner bus bars which are therefore connected via a conducting path across the propagation path at the ends of the transducers.  Further reduction in the widths of the inner bus bars and consequent increase in resistive losses are offset by several connections to a further bus 23, 43 via groups 25 of dummy electrodes arranged at null points in the weighting pattern.
