Abstract: The instant invention is directed to the production of boards and other relatively thick-walled shapes of various configurations from inorganic silicates. The method for preparing such products involves five general steps: first a fully or predominantly crystalline body is formed containing crystals consisting essentially of a lithium and/or sodium water-swelling mica selected from the group of fluorhectorite, boron fluorphlogopite, and solid solutions therebetween; second, that body is contacted with a polar liquid, customarily water, to cause swelling and disintegration of the body accompanied with the formation of a gel; third, the gel is contacted with a source of large cations to effect an ion exchange reaction between the large cations and the Li.sup.+ and/or Na.sup.

Abstract: A curb inlet having a removable non-concrete gutter form, which is an arcuate, generally rectangular strip having a concave front face and a convex rear face with a plurality of handles secured to the rear face and, also secured to that rear face, a plurality of aligning horizontal sleeves each having a tube portion and a latch portion and each having a locking bolt slidably mounted in the sleeves. The form can be locked in place in a pre-cast curb inlet member by the bolts entering openings in that pre-cast member. The form retains concrete when the concrete is poured against the pre-cast member. After the concrete sets, the bolts are withdrawn from the openings and the form can be removed through an access opening therein. The form strip may be a fiberglass-plastic resin structure.

Abstract: A wind-up accessory for playing out, retrieving and storing a water ski rope and handle bar assembly is disclosed. The storage accessory includes a box enclosure having a reel and spool around which the water ski rope is wound, a crank handle coupled to the reel, and an eyebar attached to the spool for engaging a quick snap fastener attached to the end of a water ski rope. The box enclosure is provided with a slot opening through which the water ski rope is played out and retrieved.

Abstract: A computer work station assembly comprises a display having a viewing screen, a display actuator, and mounting apparatus for supporting copy material and at least the display with respect to a work surface such that the display actuator, the copy material, and the display may be disposed in line with the viewing screen of the display disposed relatively above and longitudinally spaced from the display actuator so as to minimize reflections on the viewing screen which would distract a work station operator and so as to position the display viewing screen at a predetermined focal distance from a work station operator.

Abstract: In a dual stage power transistor type amplifier in which a video signal is applied to the base of a first stage transistor and in which the output of the first stage is direct coupled to the emitter of the second or power stage, and in which the second stage has a substantially constant d.c. voltage applied to its base, and a higher constant d.c. voltage applied to its collector through a load impedance. A voltage limiting device such as a Zener diode is shunted across at least a portion of the load impedance. With the fixed voltage on the base and a limited d.c. voltage on the collector, saturation and overload of the transistor is prevented.

Abstract: Apparatus for correcting the error of a position measuring apparatus, the apparatus having a first measuring interferometer path of variable length and a second interferometer monitoring path of fixed length. Means are provided for monitoring the change in the optical path length of the monitoring interferometer due to environmental changes and for reflecting these changes in the indicated measurement of the measuring interferometer.

Abstract: This invention relates to a process for injection molding hydrosilicate glasses and apparati useful therefor. This invention is also concerned with apparati for mixing hydrosilicate glasses while in the fluid stage, i.e., when the hydrosilicate glasses have a viscosity between about 10.sup.2 -10.sup.9 poises. Finally, this invention describes materials demonstrating ready release of hydrosilicate glasses after contact in fluid form.

Abstract: Devices and processes are disclosed for the treatment of waste gases, particularly automotive exhaust gases, to remove the oxides of nitrogen therefrom. Mixed noble metal catalysts consisting essentially of platinum or palladium and at least one other noble metal selected from the group consisting of ruthenium, rhodium, and iridium are employed in combination with layered oxide support coatings to eliminate ammonia formation during the removal process.

Abstract: The invention is an improved anchor for tensioning a flexible element such as a wire, strap or cable. The anchor is normally used to hold down an object such as a trailer. It includes a generally U-shaped frame having legs including circular openings which are axially aligned with each other. A tensioning member is rotatably received in the openings, and a sleeve, which is affixed to the tensioning member, has an aperture for receiving the flexible element such that it can be wound on and unwound from the tensioning member. A locking member is removably affixed to the tensioning member and one leg of the frame to hold the tensioning member against rotation. The locking member has flanges which embrace the frame's leg and edges with a flange which engages the tensioning member to securely lock the tensioning member. The locking member may be inserted and removed without shifting the tensioning member axially.
