A bottle capping machine wherein the capping units orbit about a vertical axis and have sockets which travel past a transfer station where each socket receives a cap which is thereupon engaged by a permanent magnet and is lifted toward a sealing ram of the respective unit while the latter moves toward registry with a filled bottle. The transfer station accommodates a vertically adjustable platform which supports a chute for delivery of caps to successive sockets and a stop which centers the caps...

A mechanism for seating lids on containers including as one embodiment a vertically movable container support and a capping head having a plate and an inner disc pivotally carried on a post above the support. As the container with a lid resting on its rim moves upwardly, the plate is carried upwardly on the lid and the disc seats one side of the lid and then seats the other side on the container, thereby minimizing distortion of the lid and container, and allowing air to escape from the containe...

A method of capping a hydroxy group of a moiety, comprising coupling the moiety to a phosphor or phosphite derivative of a protected alcohol, so as to form the corresponding phosphate or phosphite between the hydroxy and phosphor or phosphite groups. The hydroxy group may be later de-capped by hydrolyzing the resulting compound to deprotect the protected alcohol and cleave the phosphate from the moiety so as to regenerate the hydroxy group of the moiety. The method has particular application to ...

To provide a capping unit, a capping method, and a droplet dispense unit capable of a liquid-filling operation to an inkjet head and recovery operation of the inkjet head in imperfect dispense condition without useless discharge of liquid dispensed by an inkjet system. A capping unit to cover a dispense head with a covering device, the dispense head including cavities to store liquid, nozzles communicating with the cavities, and a dispense device to dispense the liquid stored in the cavities thr...

An end capping machine is disclosed wherein a plastic end cap is formed and bonded to a cardboard sleeve so as to form an integral, wide-mouth container. Each cap is formed and thermoplastically bonded in essentially one-station of a multi-station operation. The machine of the present invention is particularly useful in forming oil cans, and eliminates the need for the conventional metal base and sides.

A container capping apparatus having a generally vertical tubular spindle carrying a cap holding chuck assembly is rotatable about its axis to apply a screw cap to a container with predetermined force. A control rod is vertically movable within the spindle against an actuator spring to release the applied cap from the chuck. An axle carried by the control rod projects through vertically elongated slots in opposite sides of the spindle, and is received in a control collar slidable on the spindle....

An elongate roof ridge capping member for a tiled roof includes a pair of longitudinally extending flanges interconnected by a capping section. The capping section is connected to at least one of the flanges by a re-entrant portion, being so connected to both flanges in the case of a member for a duo-pitch roof. The re-entrant portion defines a longitudinally extending recess which can receive the end of a roof tile. The flange in the recess is provided with a longitudinal ridge or the like whic...

Contacting a rough cut optical fiber end to a light-transmissible, hardenable material supported on a smooth substrate and thereafter hardening the material to form a smooth flat light transmissible surface at the end of the fiber.

An apparatus is disclosed for filling and capping a quantity of stackable containers with a fluid from a fluid reservoir. The apparatus comprises a rotary table having a plurality of apertures disposed therein for receiving the containers. Containers from a container magazine are transferred individually and placed within the apertures in the rotary table. A filling head is disposed at a second position for filling the container with the fluid pumped from the fluid reservoir. The filling head co...
