Abstract: The Accelerated Spoken English™ (ASE) course described in this invention emphasizes lesson drills using audiotapes so that students learning English as a second language respond to all language drills audibly. Neither written nor grammar exercises are used. The specific method of this invention arranges each verb into a verb table displaying the infinitive, imperative, and gerund forms of the verb and each person in the past, present and future tenses of the verb. The verb table is then presented to the student as an audible word drill requiring the student to respond with spoken English to each person in three tenses. The drill pattern remains unchanged for each new verb vocabulary word. The method of spoken language drill used to teach the English verb may be applied to any foreign language.

Abstract: This invention provides a centrifugal weir that may be placed in series with conventional piping between a source of contaminated liquid and a discharge point within an industrial setting. Further, this weir allows continuous flow from the source of contamination to the discharge point without requiring settling ponds or reservoir systems. The centrifugal forces generated on the liquid inside the rotating weir greatly accelerate settling of heavy solid material from the liquid. The invention further provides a simplified means of cleaning the centrifugal weir. In a second embodiment, the centrifugal weir uses a removable cartridge. The compact unit of the second embodiment may be used in dental offices to separate amalgam from rinse water and for limited wastewater handling in chemistry laboratories.

Abstract: The method of this invention provides a means for altering commonly available inductive voltage detector instruments into dual sensitivity test instruments. By shielding the sensor probe with a metallic material, the probe is made to be unresponsive to energized conductors in near proximity when the shield is grounded by finger contact. A single probe window is provided so that when grounded, the instrument will respond to an energized conductor in only the probe window area allowing testing of single conductors in wire bundles. When ungrounded by the electrician's finger, the instrument reverts to normal sensitivity. Provision is made for safety by isolating the metallic shield from contact with energized conductors. The method may be employed by means of a demountable accessory or incorporated into the test instrument during manufacture.

Abstract: A continuous process for reclaiming plastic scrap is disclosed. The process is particularly suited to reclaiming blow molded plastic containers which are contaminated with affixed paper or plastic film product labels, and soil, food, or motor oil wastes. The process is continuous and positively conveys materials through auger-like apparatus within a closed system.

Abstract: The present invention relates to a process for the removal of ore from the hold of a bulk carrier vessel. The prior art employes a boom mounted vacuum probe which is lowered into the ore material to effect unloading. This invention adds material handling hoses between the boom mounted vacuum probe and wheeled vehicles with attached aspirated suction nozzles. Further, the wheeled vehicles are powered from a stationary hydraulic pumping unit connected to the existing electric power of the boom mounted vacuum probe. Ore unloading efficiency is improved when the ore level in the hold reaches a depth of approximately two feet or less by providing wheeled vehicles carrying aspirated suction nozzles over the decking of the hold.

Abstract: This apparatus is a continuous processing device designed to remove labels and similar contaminants from granulated material prior to its reclamation into a manufactured product. The apparatus is particularly suited to the removal of adhesive backed product labels affixed to plastic base materials subsequent to granulation of the intact plastic item. This allows reprocessing of label-contaminated plastic containers into plastic pellets with greater economy and a higher purity of the end product. The need for this process is particularly acute with blow molded plastic containers which have paper or plastic labels affixed to large areas of their surface. Because this apparatus is continuous in operation, it can be placed in line with other automatic processing equipment such as granulators, washers, classifiers, and extruders. The success of this apparatus results from a combination of physical and thermal forces generated within the equipment which remove the adhesive from the plastic base.

Abstract: This method is an improvement of an existing apparatus and method employed to remove paper or plastic film labels from plastic blow molded bottle scrap. Mechanical improvements have been made in two areas. The first area of improvement consists of the addition of multiple stages to the vertically mounted rotating blade assembly and cooperating multiple stationary elements within the stator assembly. The second area of improvement is within the air induction system and consists of improvements of the flow and control of the air stream which entrains the waste from the process mass. The method improvement of this invention results from the employment of these mechanical advancements.

Abstract: The present invention is a process for separating granulated plastic oil containers from the oil residue remaining within the containers after use. In this process, the plastic oil container is granulated prior to the separation of the oil from the plastic; the subsequent separation is done mechanically without washing or solvent deployment. The system comprises a conveying system, a size reduction means operating in conjunction with a centrifugal separation apparatus, and a means of segregating and storing the separated oil and the plastic granulate. In a first embodiment, the process is employed as a truck mounted unit for mobile processing of oil containers at the location of utilization. In a second embodiment, the process is employed as stationary processing facility.

Abstract: The present invention is a centrifuge device which separates chips or shreds of containers from whatever liquid residue remains within these containers. Though this technology is suitable for a number of applications, a primary objective is the separation of the recyclable plastic of a motor oil container from the remaining re-usable motor oil within the container after the container has ostensibly been emptied. It is an objective to accomplish this in an economically advantageous manner which uses neither a solvent nor a wash process, and which reclaims the oil in a suitable form for reprocessing. In its preferred embodiment, the present invention may be utilized as a compact, free-standing size reduction and reclaiming device at the location where the container is used, such as in automotive service stations, and the like. In a second embodiment, production units may be used in plastic reclaiming plants where large quantities of a given plastic container are being centrally processed.

Abstract: The present invention is a method for using a batch centrifuge to separate the granulated material of a container from whatever liquid residue remains within the container. Though this technology is suitable for many diverse applications, a primary objective is the separation of the recyclable plastic of a motor oil container from the remaining reusable motor oil within the container after the container has ostensibly been emptied. The apparatus may be utilized as a compact, free-standing size reduction and reclaiming device at the location where the container is used. It uses neither a solvent nor a wash process and reclaims the oil in a suitable state for reprocessing. In a second method, a rinsing mechanism is employed by which a residual liquid waste, such as soap, may be concentrated and separated without introducing this residual liquid waste in dilute form into the waste water treatment process.

Abstract: This invention pertains to an apparatus which facilitates the curb-side collection of recyclable waste products. It does so by incorporating a size reduction cutting or crushing head into a mobile unit designated primarily for truck mounting. The conveying and processing apparatus further provides a means whereby said recyclable waste products can be conveniently fed into the unit at a location, or multiple locations, convenient to an operator, or multiple operators, during said collection procedure. The apparatus provides the conveying and processing equipment necessary to move said recyclable material from the feed location to a size reduction cutter or crusher head mounted centrally to any such conveying components. Upon completion of the size reduction stage, the unit further provides the means of holding the processed recyclable material prior to its discharge at a collection facility.

Abstract: The present invention is a method for using a horizontal, continuous process auger centrifuge to separate the granulated material of a container from whatever liquid residue remains within the container. Though this technology is suitable for many diverse applications, a primary objective is the continuous separation of the recyclable plastic of a motor oil container from the remaining reusable motor oil within the container after the container has ostensibly been emptied. It is an objective of the method to accomplish this separation in an economically advantageous manner which uses neither a solvent nor a wash process, and which reclaims the oil in a suitable state for reprocessing. In a second method, a rinsing mechanism is employed by which a residual liquid waste, such as soap, may be concentrated and separated in a first rinse stage without introducing the residual liquid waste in dilute form into the waste water treatment process.

Abstract: This invention pertains to the cutter area of size reduction equipment for plastic or other waste material. The primary objective of this invention is to provide a feed mechanism and secondary cutting section to an existing shredder technology. Inasmuch as a properly designed shredder mechanism will produce a uniform material width, a feed mechanism was developed to maintain the orientation of the shreds as they exit from the shredder, and to meter them into a secondary cutter system at a predetermined rate of speed. Said secondary cutter system is so designed that the subsequent cutting action is at a plane perpendicular to the first cutting action. By maintaining said orientation of the shreds, and by controlling the rate of in-feed to the secondary cutter, a uniform chip is produced with a predetermined width and length dimension.

Abstract: This invention pertains to the cutter area of size reduction equipment for plastic or other waste material. The primary objective of the invention is to provide a primary and secondary cutting area within the cutting head assembly so that the granulate is properly sized upon discharge. In the normal passage of the material through the cutter assembly, this reduction to a predetermined size is accomplished in the primary cutting area. However, if material inadvertently passes through the primary area without being properly sized, it will be appropriately dimensioned in the secondary cutting area prior to discharge. The invention pertains to a cutter mechanism which uses a single plane of counter rotating, alternating cutters in conjunction with a stationary cutting surface to achieve the primary and secondary cutting actions. The invention further addresses design considerations of the locating means of both the shaft mounted cutter assemblies and the stationary cutting surfaces.

Abstract: This invention pertains to a device which is attached on rotating or moving equipment for the purpose of monitoring unsafe levels of equipment vibration. The invention comprises a mechanical assembly which is adjustably sensitive to the vibration amplitude of its given application. The monitor is so designed that it does not include the electronic switching device as an integral part of the invention. Rather, commercially available switching devices (proximity switches) are used as the electronic switching component. In the preferred embodiment, the unit is sensitive to vibration in any plane. The vibration monitor is a signaling device; it can be used to sound an external alarm, engage safety equipment, or disengage or stop moving equipment. It was developed as an inexpensive, rugged, device which can be used in conjunction with general purpose proximity switches to give vibration monitoring capability to an existing proximity switch product line.
