Abstract: A bristle strip for rotary brushes comprising a supporting channel in which the closed ends of the U-shaped bristles are clamped. The channel is provided with laterally-extending guide members mounted directly thereon that project laterally outwardly beyond its side flanges to guide the strip when it is inserted in a guide track on a rotary drum and to retain it therein. Due to the simple nature of the strip it can be produced at a low cost without special tooling.

Abstract: A bristle strip for rotary brushes comprising a channel in which the closed ends of the U-shaped bristles are clamped. The channel is provided with pairs of opposed slots in its upstanding flanges or sides which receive guide lugs that project laterally outwardly to guide the strip when it is inserted in a guide track on a rotary drum and to retain it therein. Each lug is provided with an indentation for engaging the mat of bristles to hold the lug in a lateral fixed position. Due to the simple nature of the strip it can be produced at a low cost without special tooling.

Abstract: A rotary phased radial thrust variable drive transmission which is lcoated between an input driving member, such as the pedal-driven sprocket of a bicycle, and an output driven member, such as the hub of a bicycle wheel which are mounted for relative rotation on a common axis, such as the axle of the rear wheel of a bicycle. The transmisison includes radial thrust linkages which are carried by the input driving member for cooperating with a surrounding cam ring assembly having a normally fixed cam profile providing a torsional thrust on the output driven member to cause rotation thereof. The cam ring assembly is selectively adjustable to vary its profile.

Abstract: A system for supplying liquid in large bottles from a point where they are filled to a dispenser having a reservoir for receiving the liquid. The bottles each have a neck which carries a cap unit for closing the spout thereof. Each cap unit has an outlet valve that is normally closed. The reservoir has means for supporting another normally closed inlet valve in a neck-receiving socket. When the neck is slipped into the socket the outlet valve of the cap unit is opened and substantially simultaneously the inlet valve for the reservoir is opened thus allowing flow of water from the bottle into the reservoir. When the bottle is removed from the reservoir as the cap unit is withdrawn from the neck-receiving socket, the outlet valve in the bottle neck cap unit is positively closed and the inlet valve of the reservoir automatically closes.

Abstract: A polygonal protective carton for a rotary broom which has a central support tube and bristles extending radially therefrom to form a substantially cylindrical broom. The carton includes ends which have hubs that extend into the open ends of the tube to substantially suspend the broom in the carton to prevent shifting therein which would cause damage to the bristles.

Abstract: A clamping means for clamping the wires of a saddle to the upper end of a support post of a bicycle frame or the like. It consists of a lower cradle support clamping member and a cooperating upper clamping member which are mounted on the post to permit tilting of the saddle. The clamping members are so designed that they can be extruded from metal with a post-receiving socket at the lower side of the lower member. This socket, because the lower member is extruded, has a flat inner wall and side walls extending linearly in spaced relationship, with the side walls being at sharp angles to the inner flat wall to provide sharp corners for engaging the sides of the post at a fulcrum formed thereon to prevent lateral displacement of the lower cradle support on the post.

Abstract: An expander for a bicycle seat support post inserted into a tubular socket of the bicycle frame. The post has an expandable collar which is expanded by means of a wedge-like expanding member which projects from the collar and which is moved axially thereinto by means of a tension link. Movement of the link to pull the wedge-like member farther into the collar is accomplished by a screw angularly supported on the post at an angle of less than ninety degrees to its axis.

Abstract: Bag-in-box packaging of products which will not readily flow under gravity conditions for discharge. The bag is of special three-ply form to provide separate product and pressure chambers. Coupling fitments are connected independently to the respective chambers. When it is desired to dispense the product, the product fitment is exposed at a wall of the box along with the pressure fitment. A dispensing valve on the product fitment is opened and pressure is supplied and maintained in the pressure chamber to expand it and exert pressure through the baffle wall on the product in the product chamber to aid in the dispensing of the product therefrom. Before applying dispensing pressure, the box is disposed in an enveloping pressure-resisting unit. A novel method is provided for efficiently producing the special bag.

Abstract: A push broom having a head formed from a bristle strip or strips of the type consisting of a channel with U-shaped bristles extending downwardly therefrom and bent into an oval formation with curved ends. The curved ends receive complemental curved clips which are slipped downwardly over the curved channel ends and are clamped thereto. The clips may have depending flanges which overlap the upper portions of the bristles. A reinforcing member may be inserted and clamped in the oval formation. Also a special strong connection may be provided to connect the handle to the head.

Abstract: A tear-off tab structure applicable to a self-closing dispensing valve structure of the toggle type mounted on a spout in which passage to the outlet is normally-closed by an axially inwardly-extending flexible wall structure that can be flexed by a toggle lever carried thereby to complete a discharge passage to the outlet. The tear-off tab structure substantially covers the outlet and to give access to the spout through the outlet the tab structure must be disturbed thereby giving evidence of tampering.

Abstract: A machine for automatically filling the capped spouts of flexible bags of a continuous strip which comprises a strip-feed section, a separated bag-feed section, a separator section and a filling and uncapping/capping section. The strip-feed section feeds the strip to the separator section where the leading bag is separated from the strip and is immediately advanced by the bag-feed section to the filling section. At the filling section, the bag is uncapped, filled and recapped.

Abstract: A substantially flat collapsed plastic bag with an evacuation form unit insert positioned therein as manufactured to serve as a form about which the filled bag will collapse as it is emptied. The form unit comprises a ring for mounting the unit on the spout of the bag and a multichannel form extending radially from the ring and hingedly connected thereto. A simple method is provided for manufacturing the bag with the form unit insert.

Abstract: The invention provides an energy-efficient process and apparatus for removing adsorbed material, such as organic solvents, from an adsorber. In a first step, heat from a heat storage means is used to desorb both the adsorber and an auxiliary adsorber. Once the auxiliary adsorber is desorbed and cooled, desorption of the adsorber continues as the solvent is removed in a condensing system. Once the adsorber has been thoroughly heated, the flow of gas therethrough is reversed, thereby transferring heat back to the thermal regenerator and effecting further desorption from the main adsorber, the material thus desorbed being captured in a condensing system and in the auxiliary adsorber.

Abstract: A wrench comprising a handle carrying a flexible strap that is arranged as a loop with both of its ends anchored to the handle. A loop-adjusting slide is mounted on the handle for movement relative to the anchoring point and has the doubled ends of the strap slideably passing through it outwardly of the anchoring point so that movement of the slide adjusts the size of the loop. A ratchet is provided to hold the slide member in loop-tightening position and a spring returns it to its original position upon release of the ratchet.

Abstract: A disposable container assembly which is especially useful for containing, shipping and dispensing liquids or semi-liquids in bulk. It comprises a knocked-down fiberboard container body and end structure which can be set up on a pallet into a substantially rigid multi-sided polygonal drum-like container for receiving a flexible plastic bag that is to be filled with the substance to be dispensed. The bag is provided with a dispensing spout that is locked in dispensing position in one side of the fiberboard container to hold the bag in position in the container during filling, with its outer end exposed and which has a diaphragm type seal at its inner end. For dispensing, normally this seal is ruptured by a special cooperating probe which is inserted through the exposed outer end of the spout to withdraw the contents of the bag but in other cases the bottom of the bag can be ruptured directly through an opening in the pallet.
