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: This apparatus incorporates an electric motor disconnecting safety switch within the motor's electrical terminal housing. This results in a single, compact device directly mounted to the electric motor body which is used for the safety disconnect as well as the termination point for the incoming power leads and the motor wire taps. The apparatus may be employed as a disconnecting device for single phase and three phase alternating current motors as well as various configurations of direct current motors. The apparatus further includes a simple and economical adapter plate mounting configuration which accommodates the device to a multiplicity of motor frames. This apparatus is used in three embodiments: the first being a rotary tumbler switching device with an external rotary hand operator; the second device being a draw-out disconnecting means; the third device including an integral motor starter which provides both disconnecting and motor controlling functions.

Abstract: A method for combining the operation of the electrical disconnecting safety switch of an electric motor within the motor's electrical terminal housing. This method of operation results in a single, compact housing directly mounted to the electric motor body which is used for both the safety disconnect function as well as the termination point for the incoming power leads and the motor wire taps. This method of operation may be employed for single phase and three phase alternating current motors as well as commonly wired direct current motors. The method further provides for a simple and economical way of mounting the device to a variety of motor frames with the use of appropriate adapter plates. The incorporated motor safety disconnect function is available in either of two configurations. The disconnect function may be operated as a rotary tumbler switch with an external rotary hand operator which allows a fully weatherproof design.

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 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.
