Abstract: An animated coin sorting bank that provides a unique form of animation when a coin is deposited therein, and which sorts coins of different diameters. A coin deposited in the bank moves under gravitational/inertial forces from an inlet to a sorting area. As it moves between the inlet and the sorting area, the coin moves through an arcuate segment in which it engages and rotates a display member. Preferably, a composite image is formed partly on the display member and partly on a front cover, so that when the display member is rotated an element of animation of that composite image is produced. After releasing from the display disc the coin continues to move under gravitational/inertial forces to a sorting area in which the coin is sorted according to its diameter. According to the preferred embodiment a high speed rotation of the display member and a high speed sort is effected, in order to enhance the visual animation produced.
Abstract: A 2-pole limited angle torque motor including a rotor assembly having one or more permanent magnets which are magnetized in the diametrical direction and a stator assembly having a pair of stator magnetic pole blades surrounded by a high density layer wound stator coil, with stator pole flanges at opposite ends of the stator magnetic pole blades which create a cross flux through the stator and rotor assemblies that produces a limited angle turning torque in the motor. The permanent rotor magnets along with stator magnetic poles and magnetic housing produce a magnetic reluctance torque that can be controlled to obtain a desired magnetic centering or de-centering spring rate for the rotor at a particular torque or power level. A magnetically saturating flux path may also be made to occur in the motor at the end of the rotational design stroke of the motor to provide a magnetic stop for the rotor shaft.

The method comprises polymerizing a 1-olefin or a mixture of 1-olefins in the presence of(a) at least one transition metal halide catalyst,(b) at least one alkyl aluminum compound containing up to about 15 carbon atoms in each alkyl group and up to about 40 carbon atoms per molecule as a co-catalyst, and(c) a saturated alkyl fluoride.The homopolymers and copolymers prepared in accordance with the method of the invention generally are characterized by a high viscosity index such as between about 100 to 300. The homopolymers and copolymers are useful as synthetic lubricants and as additives to synthetic or mineral oil lubricants for modifying the viscosity index characteristics of the lubricants.
Abstract: A card frame for housing electrical circuitry mounted on cards comprises end plates (10) separated by front and rear cross rails (12, 14) that mount card-guides (16) in which the cards can slide. Each card guide (16) comprises end elements (28a, 28b) engageable with the front and rear cross rails (12, 14) in first and second positions (FIG. 1 and FIG. 2) spaced in both the top-to-bottom and front-to-rear directions of the card frame. Each card guide (16) additionally comprises a shank (30) formed separately from the end members (28a, 28b) and assembled with them. If the shank (30) is of a first length the end elements (28a, 28b) will engage with the cross-rails (12, 14) in the first positions to accommodate a card of a first height, whereas if the shank (30) is of a second, smaller length the end elements will engage with the cross rails in the second positions to accommodate a card of a second, greater height.
Abstract: A multiple thermocouple connector panel including a row of standard thermocouple connectors having terminals with rear ends normally adapted to be connected to lead wires, characterized by terminal extenders connected to such rear ends which extend the effective length of the terminals to the rear of the connectors so as to provide for ease of attachment of lead wires after assembly of all the connectors in the panel. The connectors may be mounted between a faceplate and a mounting plate with the faceplate and mounting plate abutting respective proximal surfaces of the connector housings. The mounting plate is made of insulating material and is provided with terminal openings through which the terminal extenders extend and project beyond the rear of the mounting plate, each terminal being transversely located by a respective one of the openings and mutually insulated by a portion of the mounting plate.
Abstract: Motor includes an internal torsion spring which provides for null centering of the rotor assembly while minimizing bearing load reactions and related friction. Two such centering springs may be provided whereby in the event one spring should fail, the other spring will still be operative to perform the desired null centering function. Also, an internal leaf spring interiorly of the rotor casing absorbs the full stroke rotor inertia without part damage or deformation. The null position bias of a motor driven valve may be established by adjustment of a pair of set screws which adjust the rotor assembly off null without inducing undesirable friction. The stator electrical torque null of the motor may also be set by providing an adjustable eccentric pin in the stator housing which is engageable in a notch in the rotor casing.

Abstract: A process and composition for adhering a rubber compound to a fluoroplastic and/or to metal. The invention contemplates the use of separate, sequentially applied adhesive layers to the fluoroplastic or metal substrate. The last applied layer, a rubber cement, allows the metal or fluoroplastic to be adhered to the uncured rubber compound which is subsequently vulcanized. The invention finds particular utility in securing a fluoroplastic and a rubber lining to steel or other metallic surfaces. A typical use is the lining of the interior of a railroad tank car, providing protection from corrosive or hostile environments experienced when the tank car is transporting acids or other caustic materials. Other uses include the lining of chemical process vessels and piping.
Abstract: A card frame for accommodating circuit cards comprises side plates (10) joined by cross rails (12). The side plates (10) are die cast and have ridges (30) integrally cast therewith, the opposed faces of the ridges acting as ledges. The ridges (30) extend in the front to rear direction of the card frame. The cross rails (12) are secured at their end to the side plates (10) by a single screw (16), twisting of the cross rails 12 being prevented by their abutting the above-mentioned ledges.
Abstract: A figurine having a form retaining shape. The figurine comprises a body portion and a head portion connected with the body portion. The body portion comprises (i) a tubular outer covering, (ii) a fill material substantially filling the tubular outer covering, and (iii) a piece of elastic extending along at least a part of the tubular outer covering. The piece of elastic is in a partially tensioned state resulting from being fixedly secured under a state of high tension to at least two points spaced apart along the length of the tubular covering and then being allowed to relax to a partially tensioned state and being held in the partially tensioned state by the tubular outer covering. The piece of elastic allows the body portion to be manually deformed against that bias. The piece of elastic returns the body portion to the predetermined shape when the deforming forces are removed.
Abstract: Extremely fine abrasive particles are incorporated in an elastomeric resin body or coating to produce abrasive articles exhibiting cushioned or resilient yielding qualities having a dual response to in-service conditions. These performance characteristics are accomplished by a structure whose working surface and underlying supporting means produce two distinct and complementary abrading actions, one hard enough to sharpen a hardened cutting tool and to smooth the adjacent surface, and a second of being virtually simultaneously micro-deformable, via the mechanisms of cold flow, at or near maximum or optimum sharpening pressure. Such abrasive articles allow limited local displacement of a volume of the abrasive surface layer in a continuous wave to lift the surface at the tool edge to a height slightly beyond the plane of the edge being sharpened to "wipe" and so refine the extreme edge of the cutting tool and to remove the "wire-edge" as only athree-dimensional form of contact will accomplish.
