Abstract: A harvester for nut-bearing trees comprising a self-propelled chassis having a forwardly projecting, vertically shiftable frame carrying a tree-shaking mechanism and a flexible fabric canopy foldable from a generally transverse, transport position relative to the chassis to an inverted cone-shaped configuration surrounding the trunk and lower limbs of a tree. A portion of the cone-shaped configuration is defined by a rigid vertically inclined wall having windows for the operator to view the tree being approached and the interior of the canopy during the tree-shaking operation. Nuts, hulls and trash shaken from the tree into the canopy are carried by conveyors through a trash-separating zone and then through a dehuller. The separated nuts are then sized and bagged according to size by mechanisms mounted on the self-propelled chassis.

Abstract: Applicant's invention is a lightweight solar collection system, supported overhead, having a parabolic reflecting trough which continuously rotates about a fluid-filled collection conduit located at the trough's focal point. The system is supported overhead preventing bending of the collection conduit, ensuring that solar rays reflected off the trough will continuously focus on the conduit. A tracking system, cooperating with the reflection assembly, monitors the location of the sun, cuing the motor when rotation of the trough is required for maximum heat collection. The efficiency acquired through a reflection assembly supported and braced overhead used in cooperation with a system monitoring movement of the sun, allows solar heat collection for operation of a cooling and heating unit simply and economically.

Abstract: A method and apparatus for delivering metered and atomized quantities of liquid to an internal combustion engine wherein the liquid is metered in a T-shaped fitting having a liquid supply arm, an air arm which is perpendicular to the supply arm, and a delivery arm is aligned with the supply arm. Liquid is pumped from a liquid source to fill the supply and part of the delivery arm of the T-shaped fitting. A predetermined pulse of pressurized air is delivered to the air arm of the T-shaped fitting, transversely striking and severing the accumulated liquid in the delivery arm from the liquid in the supply arm to form a liquid slug. The pressurized air pulse forces the liquid slug out of the T-shaped fitting into an acceleration pipe, accelerates the liquid slug through the acceleration pipe, stores kinetic energy in the moving liquid slug, moves the liquid slug through a nozzle, atomizes the liquid slug, and cleans the nozzle and preconnected passages of residual liquid.

Abstract: A bleaching composition comprising a partially saturated carrier and a bleaching agent prepared by first mixing the dry carrier with the dry bleaching agent and then adding water while continuing mixing to produce a moist powder. This powder is used in a tumbler with at least partially nonsynthetic dyed fabrics to dry bleach or fade the dye from the fabrics. Specifically, the bleaching composition is a mix of potassium permanganate as the bleaching agent and diatomaceous earth as the carrier and is tumbled with the fabric to remove the dye from the fabric. The tumbling causes repeated contact with the bleaching agent and removes the dye in the fabric.

Abstract: A process for the forming and use of a coherent abrasive suspension jet, which involves treating water with additives to give the water a high shear dependent viscosity or viscoelasticity, or a moderate yield value, and suspending fine, abrasive particles within the treated water. The suspension that is formed may be retained in a reservoir prior to use, and requires no agitation or stirring as a slurry solution would require. The suspension that is formed allows for the use of an abrasive jet nozzle that requires only a single supply conduit and requires no mixing chamber, collimating cone, or collimating tube, as conventional jets require. The coherent abrasive suspension jet medium allows for the use of much lower pressures, much finer orifices, and much simpler operations. The process overcomes many of the difficulties associated with the reduced velocities and increased jet diameters that are attained by conventional abrasive jets.

Abstract: A method for rapidly detecting and locating reinforcing steel corrosion in concrete structures using non-linear harmonic and intermodulated frequencies of electromagnetic signals. The method comprises transmitting either a single primary frequency or two primary frequencies into the concrete structure in the general direction of the reinforcing steel. The reflected/generated signal, which is composed of the primary frequencies and of various harmonics and intermodulation components, is received, filtered, and amplified. A third order harmonic frequency is isolated with a band pass filter, is amplified, and is compared with the amplitudes of the primary frequencies. Intermodulation frequencies, primarily the combination of the primary of a frequency and the second harmonic of a second frequency, or the primary of a second frequency and the second harmonic of a first frequency, are isolated by appropriate band pass filter, are amplified, and are compared with the primary frequency or frequencies.

Abstract: A device for providing fluid cross over in a milling operation is set forth. It is particularly used by connection to a pipe string which supports the milling device for cutting junk from a well. It features an elongate hollow tool body having a central portion which defines a trash receiving chamber. There is a pipe inserted into this chamber from below for introducing return fluid after cutting which is laden with metal shavings, chips, and trash. In this chamber, fluid flows upwardly through the pipe, and trash collects in the chamber by surrounding the pipe falling to the bottom of the chamber by weight. The chamber is limited at the top end by transverse wall which has a number of perforations having an aggregate cross sectional area to prevent fluid flow restriction.

Abstract: The present disclosure is a nozzle which is comprised of an inlet, an outlet, and an elongate cylindrical housing closed by heads or covers. Within the housing there is an elongate chamber means. Multiple plates extend transversely across the chamber means and are drilled with a number of holes to provide an adequate cross sectional area for a water flow or fluid flow through the chamber. There is an additional transverse plate with holes therein. A number of flexible bendable nylon strings are positioned so that the strings have ends, and the strings are positioned so that the ends are directed toward the outlet. Fluid flow is improved by reduction from highly turbulent flow to laminar flow to string line flow.
