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. A lid magazine is d...

A pen capping mechanism for use in an X, Y graphics plotter, or the like, having a plurality of pens with writing tips requiring sealing between periods of use. A flat bar of plastic is provided as a slider member with an upper surface adapted to sealably mate with the tips of the pens. The slider member is supported for longitudinal movement on a support track and is moved between positions by an operator connected thereto. The member has a plurality of bores therethrough through which respecti...

Disclosed is a class of poly(aminoaromatic) compounds (I) obtained by capping polymeric polyols or polythiols with aromatic amine groups wherein the latter groups are linked by --O--or --S--to the polyol (polythiol) residues. Also disclosed are the precursor poly(nitroaromatic) compounds (II) from which the compounds (I) are derived. The polyamines are characterized by amine reactivities in respect of isocyanate polyaddition reactions which allows for polymer reaction rates that are intermediate...

In a container capping machine a continuously moving horizontal conveyor is spaced below a vertically reciprocable rotary chuck for holding a screw cap in its lower end. Extending along one side of the conveyor is a continuously rotating horizontal positioning screw provided with a helical trough between the screw flights for receiving containers on the conveyor and controlling their forward movement through the machine. The portion of the trough beside the chuck has side walls extending partway...

The disclosure provides an automatic capping apparatus for placing a cap on the opening of a container and crimping the cap onto the opening to seal the container. The capping apparatus includes three operating stations through which the containers are moved on a conveyor -- an aligning station to position the container on the conveyor, a cap pickup and placing station to deposit a cap on the opening of the container, and a crimping station for crimping the cap onto the opening. Furthermore, sen...

A headset device for use with a capping machine for applying roll-on closures to a container, wherein a plurality of capping headsets is provided, each of which includes pivotally mounted cam roller and follower members operative in response to reciprocal movement of a cone-like cam member in conjunction with a resilient torsion element for generating a predetermined controlled radial force on the metal forming roller members upon axial displacement of the cam member.

A method is shown for capping a tailings pond of the type which receives fines-containing aqueous effluent from an industrial process. A mineral formulation is prepared by mixing together lime, a pozzolanic component, a sulfate component and water. The mineral formulation is applied to the surface of the fines-containing tailings pond and is allowed to harden to form a surface coating on the tailings pond.

A method of anchoring ridge-capping or hip-capping to the structure of a building. A rail fitted with a series of clips moveable therealong is secured to a hip- or ridge-board. Flanges on the clips engage the upper surfaces of a series of end-to-end cap sections forming a continuous roof capping above the rail. The clips are adjustable to suit individual applications.

A capping machine of the rotary type for closing filled bottle type packing containers for beer or other liquids which are made from a plastic material includes a lower wheel on which the bottles to be capped are placed and an upper wheel which supports closing rams which are movable vertically towards and away from the bottles by means of a cammed track. Caps loaded into a magazine are transferred one by one to the rams as the wheels turn, and the bottles are capped as the ram moves downward on...

An outwardly flanged valve cup is secured to a rolled annular edge about an opening of an aerosol can, with interposition of a sealing gasket between the flange and edge, by exerting a downward pressure on an inner part of the cap to elastically pre-stress the flange by its reaction pressure against the gasket and edge, and, while the flange is so held, outwardly expanding a skirt portion of the cup by plastic deformation to form an annular fixing bulge therein, the flange being left free to ado...
