Abstract: ABSTRACT OF THE DISCLOSURE A lower portion of water well casing in the ground is perforated by means of a toothed wheel journalled on the end of an arm pivotally carried by an elongated perforator body.  The perforator body carrier an air driven piston and actuator link connected to pivot the arm and wheel downwardly from an upward retracted position to a lower start position in which a point of one tooth and a flat end of an adjacent tooth contact the interior of the casing.  In this start position the axis of rotation of the wheel is in an over-center position, below a line between the arm pivot axis and the point of the upper one of the two teeth that contact the casing surface.  In this over-center start position, the perforation body is pulled upwardly so that the wheel teeth are pressed outwardly against the casing surface with great force by the over-center arrangement which urges the wheel axis closer to the casing.  Each tooth has a truncated cutting end that extends along a line intersecting an outermost point of the adjacent tooth to provide optimum pen-etration of the casing wall.

Abstract: ABSTRACT OF THE DISCLOSURE        Aluminum alkoxides are prepared by the reaction of impure aluminum and monohydric alcohols in a process wherein impure metallic aluminum particles are continuously fed at a metered rate into a stoichiometric excess of al-cohol.  The novel apparatus disclosed permits the contin-uous introduction of the aluminum particles into the re-actor and removal of non-reactive impurities through col-umns  of ambient temperature alcohol which avoids contact of atmospheric oxygen with the reaction products.

Abstract: ABSTRACT OF THE DISCLOSURE     A woodworking machine for tenoning and longitudi-nally profiling wooden frame elements, and more particularly window frame elements.  The machine has at least one longitudinal profiling vertical spindle associated with a work table and having tools for longitudinal profiling.  A tenoning vertical spindle is also provided and having tools for tenoning and mortising and adapted to travel at right angles to the length of the work table.  The frame elements are provided, in their longitudinal profiling setting, with tenons and mortises at their ends by transverse displacement of the tenoning spindle.  The machine is characterized in that the tenoning spindle when displaced transversely, moves at the feed velocity of the workpiece in the longitudinal direction of the work table and is then returned to its starting position.  The workpiece is moved for longitudinal profiling along the work table by means of a feed device and passes the longitudinal profiling spindle which is not longitudinally displaceable.

Abstract: ABSTRACT OF THE DISCLOSURE      Process for the preparation of organic isocyanates in which a furoxan is heated in the presence of a vicinal di-keto compound containing two adjacent keto carbonyl groups. When the furoxan ring is fused to an organic ring system di-isocyanates are produced.  An adduct of the furoxan and the diketo compound may be isolated from the reaction mixture and used as a stable isocyanate precursor in, for example, a "one-pot" polyurethane composition.  The adduct may be represented by the structure   wherein X represents an acyclic or cyclic divalent hydrocarbyl group and Y, Z which may be the same or different are hydro-carbyl groups which are either separate or combined into one cyclic system.

Abstract: TITLE OF THE INVENTION:            METHOD AND APPARATUS FOR AEROBIC DECOMPOSITION OR DRYING OF ORGANIC WASTE MATERIAL            ABSTRACT OF THE DISCLOSURE:     A process for aerobic composting or drying of organic waste materials in a composting bin and apparatus for carrying out the process.  The composting bin is formed by one or more elongate composting passageway chambers which can be aerated or vented and heated.  Each chamber encloses in sequence an intake zone, shaping zone, re-action zone, and discharge or transfer zone. Material is fed loosely through an opening into the intake zone in successive substantially equal portions or charges.  A clearing element at the intake end of the chamber inter-mittently pushes each successive portion through the shaping zone, against the preceding portion, and through the reaction zone of the chamber.  Residence time in the compost bin is sufficient for complete composting or other purposes before discharge or transfer.  In the case of a bin with two or more chambers the chambers are arranged at different levels one below the other. The bins are oppositely oriented so that the transfer of material from an upper bin feeds material to the intake zone and the steps are repeated to completion of decomposition.  For automatic process control the reaction zone is divided into separate sections for separate venting and analysis of reaction gases by section.  Separate control of aeration and heating by section is also provided in re-sponse to the gas analysis thereby provided selective opti-mum conditions for completion of aerobic decomposition.

Abstract: ABSTRACT OF THE DISCLOSURE       Sensing apparatus for monitoring the passage of objects, including people, through a doorway.  A source of radiant energy is positioned at one side of the doorway and two spaced-apart detectors are positioned at the opposite side to receive beams of radiant energy from the source.  A receiver is con-nected to each detector and produces a signal indi-cating whether the beam of radiation from the source is impinging on its associated detector or is being blocked by a passing object. Logic circuitry responds to the signals from the receivers and pro-duces a first or second output condition depending upon which beam from the source is the last one to be interrupted by a passing object.  Output circuitry coupled to the logic circuitry produces a pulse at one output terminal on a transition from the first to the second output condition indicating passage of an object through the doorway in one direction and produces a pulse at another output terminal on a transition from the second to the first output con-dition indicating passage of an object through the doorway in the opposite direction.

Abstract: ABSTRACT OF THE DISCLOSURE A manually actuable primer for an internally vented float regulated fuel bowl type carburetor employs an arrangement for minimizing variations in fuel mixture richness resulting from variations in air intake path restrictions as might be created by a clogged air filter includes a bifurcated float bowl air vent conduit with one branch communicating with the carburetor bore in the region of the Venturi and the other branch communicating with the bore outside the region of the Venturi along with an arrangement for directing displaced fuel from the fuel supply chamber directly into a conduit which normally conveys fuel from a fuel well to the Venturi region, the directing arrangement being formed as an annular insert for the fuel well, the aperture of which forms the fixed fuel metering orifice of the carburetor.  With this arrangement primer actuation pressurizes the region above the fuel in the float bowl, forcing fuel through the annular member directly into the nozzle communicating between the fuel well and the carburetor bore Venturi, while the bifurcated float bowl air vent arrangement allows a smaller vent opening into the float bowl, making float bowl pressurization priming feasible, while minimizing mixture richness changes normally associated with air intake obstructions such as a dirty air filter.

Abstract: ABSTRACT OF THE DISCLOSURE    An animal watering apparatus including a thermo insulated tank having a water chamber supplied with water with a water pipe extended to the upper portion of the chamber and a float valve mounted on the pipe to maintain a preselected water level in the chamber.  A top wall mounted on the tank provides a pair of animal drinking openings.  Covers pivoted on the top wall close the openings.  A pair of baffles extend downwardly from the inside surface of a top wall.  The baffles are located on opposite sides of the float valve and extend across the water chamber.  Opposite ends of the baffles engage the tank side walls.  The lower edges of the baffles are normally below the surface of the water to isolate the float valve and water pipe outlet from the drinking openings so that cold ambient air does not move across the surface of the water to the vicinity of the float valve to prevent the float valve from freezing in cold weather.  The baffles act as guides for directing convection circulation of the water in the water chamber around the water pipe.
