Abstract: A method and apparatus for separating aluminum-based materials from non-aluminum materials is provided. The apparatus includes a conveyor which leads into a chute. Mixed materials which may be pre-shredded travel along the conveyor and into the chute. An adjustable air header assembly is provided at the end of the conveyor within the chute which directs an air stream generally upwardly and at an angle towards the end of the conveyor and the pieces of material thereon. A predetermined air velocity and air flow is selected such that the lighter aluminum materials are lifted and blown, or propelled, a fixed distance as they emerge from the end of the conveyor and the heavier non-aluminum materials fall short of that distance. Suitable collection bins are provided at the appropriate location. The apparatus and associated method used are particularly suited to separating used food and beverage can stock before it enters a recycling station.
Abstract: A method for necking an end of a metal container include effecting initial deformation, generally radially inwardly, of an axial portion to establish a necked-in generally convex transition portion and an adjacent portion disposed between the transition portion and the container end which is initially generally cylindrical. Both portions are of reduced diameter with respect to the original can body diameter. Sequentially, through the series of formation steps, the portion to be necked in is further reduced in diameter to produce an outwardly generally convex portion disposed in underlying relationship with respect to an outwardly concave portion. A generally, radially, outwardly directed flange may be established within the end section of the necked-in portion. Apparatus to perform the foregoing forming steps consists of a plurality of die means which are subjected to relative axial movement and contact and reshape the exterior of the container portion that is to be necked in.
Abstract: A closure assembly which is adapted to be used with structural members has a pair of guides and a closure member which is in mechanical interengagement with the guides so as to permit relative sliding movement in opening and closing the closure. The closure member has a pair of tracking members disposed on opposite edges which may take the form of tape members. These tracking means are retained within the guides.The guides may have secured thereto shoes which are engaged within guide channels secured to frame members so that relative lateral movement between the guides and frames is permitted. A biasing assembly which enhances lateral tension on the closure member may be employed.

Abstract: A method of making a lead-acid battery includes providing continuous lengths of end separator stock (24) and intermediate separator stock (26) and stacks of positive (81,98) and negative plates-(83,93) with optional use of end separators. The separators are individually severed from the continuous length of stock and sequentially formed into an assembly with the individual positive and negative plates. The assembly is introduced into a battery cell container (28). A plurality of assemblies may be established prior to introduction into the battery cell container (28). In a preferred embodiment, the assembly zone (38) moves linearly relative to the cutting stations for the respective continuous lengths of separator stock and the stacks of plates and facilitates sequential establishment of the assembly without intermediate storage of the individual separators and elements. Some or all of the separators may be supplied from stacks disposed in magazines.
Abstract: An apparatus for resisting coagulation of blood, includes a blood container having disposed therein antibody to blood coagulation factors for resisting coagulation of blood. The apparatus further includes a needle and a holder for the needle which are both operatively associated with the blood container. The blood coagulation factor antibody inhibits coagulation of the blood drawn by the needle into the blood container so that an uncoagulated blood sample is obtained.
Abstract: An anti-tip hinge device for a door or a shelf, which is pivotally moved to obtain a horizontal cantilever position. The hinge device has a channel which fits into a sheath of and is connected to the door or shelf. A lever arm carries cam followers which engage a cam in the channel. The cam is supported in the channel by a pin and a spring located on opposite ends of the cam. The cam has a recess and a ramp disposed adjacent to the recess. When an overload is applied to the cantilever end of the door or shelf, the cam followers are disengaged from the recess of the cam, and push the cam inwardly within the channel at an angle to allow the door or shelf to be titled downwardly below the horizontal. This action interrupts the counterbalance spring effect on the door. A pin-hole arrangement resets the hinge device, and a lug-slot arrangement prevents the door from disengaging the hinge device.
Abstract: An apparatus and method for determining the sensitivity of MAI to different antimicrobial agents and dosages thereof is provided. The apparatus comprises a plurality of test tubes adapted to contain an amount of an antimicrobial agent to be tested and MAI complex organisms to be assayed and a separate paraffin coated slide adapted for placement in each of the test tubes. The growth of the MAI complex organisms on the slide can be used to determine the concentration of the antimicrobial agent necessary to resist MAI complex organism growth on the slide. An associated method is also disclosed.
Abstract: An apparatus for topical targeted delivery of a substance to generally the ntire or selected portions of the internal body tissues and walls of a tracheal-intubated patient's upper airway is disclosed. The apparatus includes a tube member for ventilating or oxygenating a patient's lungs that has an annular inner surface, an annular outer surface having a plurality of opening extending over a major portion of the axial extent of the annular outer surface, and at least one first conduit member that is positioned generally at least in part between the annular inner surface and the annular outer surface. The first conduit member extends over the major portion of the axial extent of the annular outer surface of the tube member. The first conduit member has a plurality of perforations in alignment with the openings of the annular outer surface for effecting delivery of the substance to the surrounding internal body tissues and walls of the patient's upper airway.

Abstract: A cycloidal mass spectrometer having a housing which defines an ion trajectory volume, an electric field generator for establishing an electric field within the ion trajectory volume, and an ionizer for receiving gaseous specimens to be analyzed and converting the same into ions which travel through orthogonal electric and magnetic fields and impinge upon a collector. The spectrometer is designed to have a plurality of ions of different mass to charge ratios impinging on the collector generally simultaneously. A processor determines the mass distribution of the ions impinging upon the collector. A plurality of electric field plates are electrically insulated from each other and may be sealed so as to define the ion trajectory volume. In another embodiment, an assembly of electric field plates are disposed within a vacuum enclosure. A miniature ionizer preferably has a miniature filament. The cycloidal mass spectrometer and ionizer may be miniaturized so as to provide for a small, readily portable instrument.
Abstract: An apparatus for administering electrical aversive stimulus is provided. The apparatus includes a remote transmitter, a receiver/stimulator, and an electrode. The receiver/stimulator is activated by an electromagnetic signal generated by the transmitter. In response, the receiver/stimulator generates an electrical stimulus pulse which is administered to the individual through the electrode. The receiver/stimulator and electrode are worn by the individual. Stimulation indicator means on the receiver/stimulator provides a positive indication that the stimulation has been administered to the individual. Various characteristics of the electrical stimulus pulse may be adjusted to vary the individual's perceived averseness of the stimulus. A method of treatment utilizing the apparatus of this invention is also provided.
