Abstract:
A mold top lifting apparatus (121) for lifting a mold top (47) generally upwardly away from a mold bottom (48) supported on a movable support means (23) for movement in a generally horizontal direction, said mold top having generally vertical opposite side surfaces and a projecting means (53) laterally extending beyond the top of said side surfaces, said apparatus including gripping means (127-137) for resiliently engaging said mold top at that projecting means (53) and lifting means (138, 138A) for moving said gripping means upwardly, wherein said gripping means (127-137) are connected to the lifting means by movable frame means(122) and include roller means (130) spaced in horizontal direction for resilient engagement with said opposite surfaces of said mold top below said projecting means, and that before lifting of said gripping means said roller means are in such a vertical position roller means (130).
Abstract:
A coil assembly (31) having a core (32) and a winding (33) on the core (32), wherein a contact element (37, 38) electrically connected to the winding (33) is both mechanically clamped and bonded to the core (32). In an exemplary microcoil assembly (31) having a C-core (32), a generally U-shaped contact element (37, 38) is bonded to each foot (34) of the core by epoxy and mechanically clamped to the core foot (34) to hold the contact element in position while the epoxy cures. One end of the coil winding is soldered to one of the contact elements and the other end of the winding is soldered to the other contact element. The coil assembly (31) is subsequently soldered onto a printed circuit board. Each contact element (37, 38) may include a pin portion (51) to be inserted into a printed circuit board.
Abstract:
A caster with a braking apparatus includes a bracket and a wheel rotatably supported on the bracket, the wheel having a radially inwardly facing annular braking surface thereon between its axle and tread. A braking member has a braking surface thereon adjacent the braking surface on the wheel, and is supported for radial movement between braking and retracted positions in which the braking surface thereon is engaging and free of engagement with the braking surface on the wheel. Radial movement of the braking member is effected by a manually actuable lever. In a preferred embodiment, the bracket is pivotally supported on a bracket support and a further braking surface is provided on the bracket support. A braking element has a braking surface facing the braking surface on the bracket support and is moved by manual actuation of the lever between actuated and deactuated positions in which the braking surface thereon is respectively engaging and free of engagement with the braking surface on the bracket support.
Abstract:
The present application relates to a method for forming a large metallic component, a friction stir welded component and a friction stir welded blank are provided. The method includes positioning a first metallic plate (101) and a second metallic plate (102) in an abutting arrangement. The first metallic plate (101) and the second metallic plate (102) have corresponding faying surfaces (105) at a point of abutment. A backing plate is attached spanning the point of abutment adjacent the faying surfaces (105). The first metallic plate (101) is friction stir welded to the second metallic plate (102) to form a friction stir weld along the faying surfaces (105). The backing plate receives an end of a friction stir welding tool curing the friction stir welding. The backing plate is removed to form a welded blank. The welded blank is formed into a component form. The component is heat treated and aged to form the large metallic component. The friction stir weld in the welded blank has a stable microstructure having little or no abnormal grain growth during elevated temperature forming, heat treatment and aging.
Abstract:
A pressure and thermostatic relief valve for a pump housing is disclosed. The relief valve includes both a pressure relief valve mechanism and a thermostatic or temperature relief valve mechanism. A pump housing incorporating the pressure and thermostatic relief valve is also disclosed.
Abstract:
A particulate feeding apparatus (10) for applying particulate, such as super-absorbent materials, to a substrate, such as a fibrous web. A feeder tube (20) for the powder and a rotary gate valve (40), including one or more holes, are provided. This structure may then intermittently feed particulate to an eductor or venturi nozzle (30). The rotary valve (40) provides an intermittent supply of particulate to a relatively low-pressure zone at the nozzle formed by the venturi action of the passing air stream and the particulate may be distributed precisely where desired. A process for delivering powder to a substrate in precise amounts and distributions patterns is also disclosed.
Abstract:
The present disclosure provides a fluid pump having a pump motor, a pump drive shaft and a vane pump assembly. The pump assembly includes a pump housing having fluid inlet and outlet ports. The pump assembly also includes a distal bearing member having first and second sides and a second side, a plurality of inlet orifices, and a cavity formed in the second side. A first cam ring, having an elliptical interior opening, is disposed within the pump housing adjacent the distal bearing member. A rotor is disposed within the opening in the first cam ring. This rotor has first and second sides, a cavity in the first side, and a plurality of radial slots for sliding vanes. The vane pump assembly also includes a second cam ring, having an elliptical shape, disposed in the cavities formed in the distal bearing member second side and the rotor first side. In addition, the vane pump assembly includes a proximate bearing member disposed within the pump housing adjacent the first cam ring and having a plurality of outlet orifices.
