Abstract: An improved attachment fixture is provided for securely mounting an adhesive attachment such as a thread screw, patch, or the like onto a substrate. The improved fixture, which is adapted for construction as a one-piece plastic molding, is temporarily secured to the substrate in a first position with the attachment substantially out of bearing engagement with the substrate and then switched to a second position applying a positive force urging the attachment into bearing engagement with the substrate. The fixture is allowed to remain in the second position for a period of time sufficient for curing of an adhesive material applied to the attachment/substrate interface, after which the fixture may be removed. In some forms, the improved fixture maintains the orientation of the attachment during movement into bearing engagement with the substrate thereby preventing uneven distribution of or uneven application of forces to the adhesive material.

Abstract: A termination system in an electrical connector for coupling a coaxial cable to a terminal member. A strain relief component includes a crimpable portion for clamping onto the insulation surrounding the conductor of the coaxial cable and an outwardly projecting portion for capturing the drain wire of the cable. The strain relief component is readily applicable for coupling a generally flat undercarpet coaxial cable in a circular connector. A circular clamp nut holds the strain relief component in the connector with the conductor terminated to the terminal member and the drain wire in engagement with the housing of the connector. An adapter is provided between the strain relief component and the circular clamp nut for adapting the flat configuration of the cable to the circular configuration of the clamp nut and connector.

Abstract: The invention relates to a terminating connector for use with individual conductors of a shielded coaxial type flat ribbon cable assembly. A bushing is threaded onto the outer sheath of the individual conductors and holds a drain wire which is connected to a shield of the individual conductors between the bushing threads and the outer sheath of the conductor. The bushing is then secured to a shielding housing by means of a securing assembly with the shielding housing including a central contact in insulative isolation therefrom and contacting the central conductor of the conductor. Locking means serve to engage a like locking assembly of a corresponding connector to provide a tight secure shielded connection between the individual conductors of the flat ribbon cable and equipment or other like individual conductors of flat ribbon cable.

Abstract: An improved freezeproof valve assembly is provided for a water hydrant, such as an outdoor drinking fountain or the like. The valve assembly comprises a sump housing for installation below the ground frost line and for connection between a water supply pipe and a standpipe, the latter being coupled in turn to a fountain bubbler head or the like. A control valve within the sump housing is opened pneumatically upon depression of an actuator button on the fountain to permit water flow from the supply pipe through a main jet pump which draws an induced water flow from within the sump housing through an induction port thereby providing a combined water flow through the standpipe to the bubbler head. This combined water flow is maintained substantially constant by a float-activated refill valve which permits a refill water flow from the supply pipe into the sump housing sufficient to maintain the housing water level above the main jet pump induction port.

Abstract: Apparatus is provided for separating and lifting units, such as insulated glass window or door units, one at a time from a stack of units. The apparatus comprises a frame which supports a movably mounted suction platen for vacuum engagement with an upwardly presented surface of the uppermost unit in the stack and a push block for bearing engagement with a peripheral edge of the unit immediately below the uppermost unit. A pneumatic cylinder assembly reacts between the frame and the suction platen to displace the platen and the engaged uppermost unit with respect to the push block and the underlying units in the stack whereby the uppermost unit is separated from the underlying units. The suction platen remains in vacuum engagement with the separated unit to permit lifting and carrying thereof to an alternative location. Controls facilitating operation of the apparatus are also disclosed.

Abstract: A system is provided for dispensing curable compositions formed by a mixture of first and second materials which, when mixed in prescribed ratio, interact with each other to provide a relatively rapidly curable composition, such as a polymerizable epoxy resin or the like. The materials are individually pumped and metered through a first mixer and a dispensing valve to a dispensing nozzle. During start-up, the dispensing nozzle is closed, and the initial mixed composition is diverted through a bypass valve for dilution and mixture with a diluent stream of the first material in a second mixer and for return of the diluted mixture to the supply reservoir of the first material. When a homogeneous mixture of prescribed ratio is achieved at the outlet of the first mixer, the bypass valve is closed and the dispensing valve can be opened to allow dispensing of the composition.

Abstract: A method is provided for rapidly and thoroughly curing a heat curable adhesive substance by application of radiation heat energy without excessive temperature elevation of the adhesive substance. The method comprises the controlled application of radiation heat energy to the adhesive substance for elevating the exposed surface of the adhesive substance to a predetermined maximum temperature level. The radiation heat energy is then alternately removed from the adhesive substance to allow the exposed surface to cool partially, and resupplied to the adhesive substance to reheat the exposed surface to the predetermined maximum temperature level. This alternating controlled application of the radiation heat energy produces a thermal oscillation within the adhesive substance resulting in a rapid temperature rise and corresponding rapid cure time of portions of the adhesive substance not directly exposed to the radiation heat energy.

Abstract: A method and apparatus making use of that method for applying pressure to an element to be adhesively or comparably secured to a substrate. An example of such an apparatus is found in an adhesive patch and means for applying the patch to a surface which may have been ruptured.

Abstract: A dispensing cartridge for separately storing two materials until the time of use in two compartments divided by a barrier assembly. The elements that comprise the barrier assembly are used to divide the cartridge into two compartments, to mix the two materials, and to extrude the mixed material.

Abstract: An electrical connector includes a connector body having a U-shaped alignment cavity configured for snugly receiving a coaxial cable and an elongate contact extending into the cavity from a point disposed along the base thereof, the contact being adapted for piercing an intact portion of a coaxial cable received within the alignment cavity for making electrical connection with the central conductor of the cable. A pair of additional contact members extend into the alignment cavity and are adapted for piercing intact portions of the coaxial cable for making electrical connection with the conductive braid encircling the central conductor. Movement of the central conductor away from the elongate contact is inhibited by a cable piercing head of the contact and can be further precluded by a plunger which abuts the central conductor directly opposite the elongate contact.

Abstract: A coaxial connector for a coaxial cable of the type having an inner conductor encircled by an annular insulating layer, an outer conductor, and an insulating jacket has a metal body with a rear opening for receiving the cable. A rear clamp nut threadingly engageable with the rear opening moves axially within the opening upon rotation to provide an axial force. A clamping ring and a stationary ring securely hold the outer conductor therebetween upon application of the axial force to the clamping ring. A cylindrical rigid member which has compressive material covering its inner surface, outer surface and one end surface and which is coaxial with the cable is disposed between the rear clamp nut and the clamp ring. As a result, when the rear clamp nut is rotated relative to the body, the cylindrical end surface cuts through the compressible material which is compressed by the axial force provided by the rear clamp nut to provide a seal between the rear opening and the cable.
