Abstract: ABSTRACT OF THE DISCLOSURE         A document file unit includes a shelf defined by a base, side walls and dividers extending between the side walls; with rods on the lower edges of the dividers for pivotally mounting the dividers between such side walls.  A resilient pad covers the floor of the file unit, the pad normally at least partially obstructing holes in the side walls which receive the free ends of the rods.  When the pad is compressed by a rod, the free ends of the rod can be inserted in the side walls, and thereafter, the pad constantly engages the rod holding the divider in the shelf.          When a divider is in place, the rod locally compresses the top surface of the pad only beneath the rod.

Abstract: ULTRASONIC LEAK HOLE DETECTION APPARATUS AND METHOD          Abstract of the Disclosure A leak detecting device for identification of can tops and similar workpieces with leak holes has a compressed gas supply chamber providing a source of compressed gas for testing the workpieces for leaks.  An acoustic testing chamber is mounted adjacent the gas supply chamber.  A sealing press is provided between the chambers for holding a workpiece in a gas tight manner so that one side of the workpiece faces the compressed gas supply chamber in a gas tight relationship and the other side of the workpiece faces the acoustic testing chamber in a noise tight relationship.  A valve is provided on the compressed gas supply chamber and is operable to admit compressed gas from the gas supply chamber to the side of said workpiece facing the compressed gas supply chamber.  An ultrasonic microphone is disposed within the acoustic testing chamber and is adapted for detecting gas noise created by gas passing through a leak hole in the workpiece.  A gas venting port is disposed adjacent the periphery of the microphone and communicates with a laby-rinth baffle with a gas vent passage leading to the atmosphere.          An electrical control receives gas leak noise signals from the microphone after the valve has opened and rejects workpieces giving off gas leak noise signals.

Abstract: Abstract of the Disclosure Novel oxime ethers and oxime esters of the formula I given herein have various advantageous effects with regard to stimulation of plant growth, particularly in the early stage of development of the plant.  Furthermore, such compounds have the property of rendering, in the sense of an antidote action, agricultural chemicals which would otherwise damage the plants (phytotoxic chemicals) more compatible with the cultivated plants.         Herbicides that are insufficiently selective can be used for example in the presence of such oxime derivatives in specific cultivated crops for combating weeds, without disadvantageous consequences for the cultivated plants.

Abstract: Dans un mur fait en blocs de béton on sait qu'il est d'usage normal de poser des blocs de béton standard avec du mortier.  Dans la présente invention il s'agit d'un petit "truss" de métal très léger qui remplace toute pose de mortier. Donc, par le fait même, le tempe requis pour la pose est de beaucoup réduit et il n'est plus nécessaire d'engager de la main d'oeuvre spécialisée : il suffit d'empiler les blocs les uns sur les autres en plaçant un "truss" entre chaque pile de blocs.  Ce "truss" servira à retenir les blocs qui sont empilés à la hauteur d'un mur normal; il servira également à retenir le ciment au moment de la coulée, et ensuite on pourra y visser soit le gyproc à l'intérieur, soit le styrofoam et les lamelles qui servent à retenir les briques à l'extérieur.

Abstract: ABSTRACT             In an oil reservoir in which the stratification of the rock permeability is insufficient to confine steam within the most permeable strata, oil can be produced by forming and expanding a steam channel through which steam is flowed and from which oil is produced.  Steam injection into the channel is then replaced by the injection of a foam-forming mixture of steam, noncondensable gas, electrolyte and surfactant to provide foam and a relatively high pressure gradient within the channel, without plugging the channel. A flow of steam-containing fluid through the steam channel is continued in a manner such that the magnitudes of the pressure gradient, the rate of oil production, and the rate of steam channel expansion exceed those which could be provided by steam alone.

Abstract: Abstract of the Disclosure A self-propelled wheeled toy includes a housing defining an external body portion and an internal chamber.          A spring-type drive motor is mounted in the internal chamber and drivingly connected to the wheels.  The motor is cocked by a manually actuatable lever pivotally mounted within the chamber and extends through a slot.  A projectile capturing member is pivotally mounted on the housing to provide a target for a projectile directed toward the toy.  Once an object is captured, the projectile capturing member pivots due to the weight of the object and engages a switch actuating the motor and causing the toy to move across a suitable supporting surface.  As the motor operates, the lever is rotated and engages the capturing member causing the member to pivot and discharge the object.

Abstract: ABSTRACT OF THE DISCLOSURE An improved process is provided for increasing the molecular weight of silicon compounds containing predominately Si-bonded alkoxy groups. The process involves hydrolyzing the silicon compounds at an elevated temperature in the presence of hydrates of at least one salt of an ammonium hydroxide and/ or metal of the first to the third principal group of the Periodic System of elements according to Mendeleeff and in an amount of at least 8 grams of hy-drated salt per mol of alkoxy group, while distilling off the alcohol as it is evolved, to form a product which does not solidify when cooled to at least room temperature.  By this process long heating times are avoided, the hy-drolysis of the alkoxy group is controlled, the molecular weight of the poly-siloxane is regulated,  the  catalyst need not be neutralized, and the alcohol split off during hydrolysis can be recovered more easily.  These organopolysiloxanes may be used in the preparation of heat resistant and weather resistant varnishes, as binding agents for mica and glass fibrics, as soaking and impregnation resins, and as components of separative coatings.

The switches are operable for providing zero, +E, +2E, -E and -2E volts across a load in some predetermined sequence for producing a desired AC voltage waveform across the load.  The di-odes also serve to clamp the common connections between their associated two semiconductor swithces to within a diode drop of the reference potential, thereby protecting the switches from overvoltage.
