Abstract: Certain 9-(.beta.-D-Ribofuranosyl)purine-6-carboxamide and other related compounds are prepared and are useful as antiviral agents.

Abstract: A solid, monolithic bicycle tire made of urethane rubber with a cured hardness of from 60 to 70 Durometer A. The tire is formed with a pair of laterally spaced bead shoulders that seat on the bead seats of the wheel rim, and is generally triangular in cross-section, with radially outwardly converging, slightly concave side walls that merge into a relatively narrow tread section. A circumferential, arch-shaped tunnel is formed in the inner side of the tire between the bead shoulders, and the material between the tunnel and the converging outer surfaces forms narrow, inwardly inclined side walls that are compressed when pressure is applied radially inwardly against the tread. The inclination of the side walls results in a substantial amplification of the deflection of the tire under impact loads, as compared to the deflection of similar-thickness side walls that are not inclined, but instead, are parallel to one another.

Abstract: A toy game includes a housing having a plurality of target members positioned in a side by side manner near one end of the housing. An attack object can move from a central position in the housing toward the target members and if correctly positioned it can interact with the target members. The attack member is capable of two modes of movement, however, it can only move in one mode at a time. One of the modes of movement is a transverse movement essentially across the width of the target members. The other mode of movement is from a starting point near the central portion of the housing toward one of the objects. If the two movements are coordinated the attack object is capable of interacting with one of the targets. A drive motor moves the attack object in each of the modes of movement via a motion diverting mechanism which is capable of converting motion of the motor into one or the other of the modes of movement at any specific instance of time.

Abstract: The invention relates to a fluid mechanism supplied with pressurized fluid by means of a "dis-engageable" valve-seat. Such mechanism further comprises a controlled and independent device for re-engaging the said valve-seat. The invention finds an application in the production of a hydraulic relief engine for use on a trailer pulled by a tractor.

Abstract: A toy steam locomotive is described which includes a small electric motor which drives an apparatus for producing a sound simulating a steam locomotive, an apparatus for producing a sound simulating a steam locomotive whistle, and an apparatus for producing a visual simulation of a fire in a steam locomotive firebox. The apparatus for producing a simulated steam locomotive sound includes a resonator and a vibrating spring. A cycling member is attached to the spring and concurrently tenses and relaxes, lengthens and shortens and associates and disassociates said spring with a sound activating member. The apparatus for producing the sound simulating a steam locomotive whistle includes a housing having a fan located therein and an air inlet and air outlet. The air outlet is associated with a whistle and a sealing member seals the air inlet, but allows air to be drawn into the housing when the sealing member moves away from the air inlet.

Abstract: A gun for dispensing a plural component system includes a housing having appropriate connections to a pressurized air supply and pressurized first and second component storage reservoirs. Within the housing are located first and second component feed ports, each having a control valve located in its interior. A valve carrier member is movably located in the housing and is moved by a trigger. The first and the second valves are connected to and moved in response to movement of the valve carrier member. The gun includes a gas passage having a gas valve located therein. The gas valve is also connected to and moves in response to the valve carrier. At the forward end of the housing is a static mixing chamber which has a discharge outlet as well as inlets leading to both of the component feed ports and to the air passage. When the valve carrier is in a first position pressurized air is introduced into the mixing chamber which purges the mixing chamber.

Abstract: A device for suspending plumbing components such as a pipe elbow or a high ear 90 elbow between the studs of a wall and retarding propagation of sound between the plumbing components and the wall has a main body or housing formed of a semi-resilient material which is incapable of transmitting a sound from a first location in this body to a second location also in the body. A first member which attaches to the wall or a strip of plumbers tape extending between the studs is attached to the body at the first location. A second member which attaches to the plumbing components is attached to the body at the second location. The first and second members are connected to the body at their respective locations such that a parallel portion of the first member is parallel with, but is not coplanar with, a parallel portion of the second member.

Abstract: A transfer mechanism for use in a toy of the type incorporating "ball people" figurines to transfer the figurines from one location to a second location includes a base radially displaced from both the first and the second locations and a carrier which is rotatably mounted on the base. The carrier includes a support member having a first end which is movable in an arc between the first and second locations and a holding member which is pivotally mounted on the first end of the support member. A platform is located at the second location and includes an edge capable of being engaged by a portion of the holding member. The holding member is capable of swinging about its pivot; then it engages the platform. The edge of the platform includes a guide and when the first end of the support member approaches adjacent the second location the guide engages the holding member tilting the holding member allowing a "ball person" to roll off of the holding member onto the platform.

Abstract: A monolithic non-pneumatic urethane tire for use on a wheel rim of the type having a pair of laterally spaced bead flanges formed with wheel rim side walls which extend upwardly from the bottom of the wheel rim is improved by providing a tire body with certain structural features and locating a tubular insert inside the tire body. The tire body has a circumferentially extending tunnel on its inside and includes side walls which converge outwardly to a thickened portion. The thickened portion forms a bead shoulder that seats on top of the bead flanges of the wheel rim and also includes a bead which extends downwardly into the wheel rim adjacent the side walls of the wheel rim. The tubular insert is a semiresilient hollow tube mounted within the tunnel of the tire body to maintain the bead portion of the tire body against the side walls of the wheel rim.

Abstract: A sound insulating support member for isolating a plumbing pipe or other tubular member from a support surface includes an insert member formed of a material substantially incapable of transmitting sound vibrations and sized to be capable of encircling the pipe or tubular member. The insert member fits within a sleeve member which is formed of a semiresilient material capable of maintaining its shape at rest but capable of being flexed when subjected to a force. Both the sleeve member and the insert member contain a slit. The insert member is retained within the sleeve member such that the slit of the insert member is aligned with the slit of the sleeve member and when both the sleeve and the insert are open the pipe or tubular member can be inserted through the slits and the sleeve and insert close around the pipe or tubular member to cradle the tubular member within the insert which in turn is fixedly held within the sleeve.

Abstract: A toy which can repetitively move with respect to the medium supporting it has a toy body with at least one appendage movably mounted to the body. A portion of that appendage is exposed from the body and is positioned to contact the supporting medium. A mechanism within the body is operatively connected to the appendage for moving the appendage such that the portion of the appendage exposed from the body can move in a first direction at one velocity and a second direction at a different velocity. A portion of the mechanism moves with rotary motion which is transferred by another portion of the mechanism to cause still a further portion of the mechanism to move with linear motion. The portion of the mechanism moving with linear motion is operatively connected to the appendage to move the appendage.
