Included are: a fan wheel for holding and rotationally transporting signatures delivered from a printing press; a pair of side guides for restricting the signatures in the width direction which are held in the fan wheel; a side-guide rodless air cylinder for moving a side guide between side-guide guide positions for guiding the signatures and side-guide retraction positions for retraction to the outside of the fan wheel in the radial direction thereof; a side-guide drive motor for moving the sid...

A delivery valve for a fuel injection pumping apparatus includes a body portion which is slidable within a bore between a pair of abutments. The bore forms part of a passage between an injection pump and an injection nozzle and the member is provided with a valve which when the member is moved under the action of fuel into contact with one of the abutments opens to permit flow of fuel from the injection pump to the nozzle. When the flow of fuel from the injection pump ceases the valve closes and...

A carrot topping machine in which carrots are delivered to an orientating apparatus by an upwardly-inclined elevator. The elevator has a box-like casing over which runs carrot-conveying flights carried by bars connected between conveying chains. A supply hopper is located adjacent the bottom of the elevator, the hopper permitting passage of the bars and flights to pick up carrots. Adjacent the top of the casing is an opening over which the flights pass so that excess carrots fall into the casing...

A delivery arrangement including a conveyor and take-off mechanism for delivering a series of printed sheets onto a pile, in which nozzles are provided distributed along the width of a sheet for directing a jet of air in a direction opposite to sheet movement. A guide plate spaced under the sheet and extending upstream from the region of the nozzles serves to confine the jet. Interposed between the guide plate and the sheet path are a series of longitudinally extending friction or land members t...

A method and apparatus for assisting in the delivery of a fetus from a womb which includes surrounding the upper portion of the head of the fetus with a plurality of flexible fingers contoured generally to the shape of the fetus's head and securing the fingers to the fetus and then applying a pull to the fingers to assist in the delivery of the fetus from the womb. A thin membrane may be provided to interconnect the fingers whereby a vacuum may be applied to further secure the fingers and membra...

Individual shelves are provided on the load transport vehicle, which may be a trailor or self-propelled steerable vehicle, so that the shelves may be dropped down adjacent to the roadway for loading and unloading, and lifted up above the clearance height of the vehicle for storage and transport. Guides and bearings are provided between the shelf and body of the vehicle so that the horizontal portion of the shelves will be parallel to the roadway in their lower loading and unloading position to f...

Delivery systems and devices for the controlled release of chemicals, including drugs, comprising a wall, formed in part at least, of a porous material, pores of which contain a hydrogel, said porous wall in contact with at least a portion of a reservoir comprised of a chemical and, if desired, a water-soluble liquid excipient and/or a detergent; process for preparation thereof, and use for the controlled release of chemicals, including drugs, to an aqueous liquid-containing environment. Emphasi...

Apparatus for delivering business forms and the like selectably in a "face up" or "face down" position, which incorporates a set of creels and a delivery conveyor that can be selectably positioned for receiving individual forms from a separator conveyor and then shingling the forms in either a "face up" or "face down" position. The creels and one end of the delivery conveyor are mounted on rotatable plates which permit either the creels or the one end of the delivery conveyor to be positioned ad...

A delivery valve for use in a fuel injection system of an internal combustion engine comprises a valve body defining a bore in which is slidably mounted a valve member which is biased towards one end of the bore by a coiled compression spring. A first circumferential groove in the bore communicates with the one end of the bore and a second groove on the valve member communicates with the first groove and is exposed beyond the other end of the bore when the valve is opened to allow fuel flow past...

A delivery bed has a seat part supported on raisable and lowerable side-pieces. A leg-support has side tubes which are journalled for axial movement on forwardly and rearwardly located pairs of support rollers journalled on bolts attached to the side-pieces. Mounted on the side-pieces are guide bars which present along the bottom edge surfaces thereof a plurality of circle-segmental latching recesses intended to co-act with circular latching flanges on the rearwardly located support rollers in s...
