Abstract: In one embodiment a hand operated machine for making curly ribbon products comprises a rotary drum that includes a station to attach the uncurled ribbons (more than one), a cutting station to cut the curled ribbons, and a stapling station to staple the ribbons together or to a card, ribbon, or the like. A handle is provided to rotate the drum and a fixed curling mechanism mounted downstream of the drum serves to curl the ribbon as the drum rotates to place the ribbon in contact with the curling mechanism. In another embodiment the machine is automated and includes a drum that has the same stations. The attaching station includes a pair of jaws that are sequentially movable one relative to the other and together to attain attaching the ribbons to the drum for the first cycle, detaching the ribbon during the first cycle and attaching the succeeding ribbon used in the next cycle for mass producing the curly ribbon product.

Abstract: A portable bow making machine with three clutches controlling the size, arc generation and a no-back clutch assuring that the belt driving the impaler assembly doesn't go into reverse The user requiring no particular skill, merely threads the ribbon in a channel under the reciprocal carriage and the two stroke operation automatically makes one of the loops of the bow. Stroking continues until the bow is complete and a stapler automatically retracts the needles of the impaler and the staple is forced against an anvil to secure the bow. The stapler is configured to hold a removable self-gluing card that is concomitantly attached to the bow. The forward stroke carries a carriage and clapper along the carriage slides, The clapper reaches a predetermined point and drops onto the impaler to secure each of the loops to the bow. The return stroke repositions the carriage for the next forward stroke.

Abstract: A feed hopper assembly particularly adapted for feeding particulate material which agglomerates has, end walls and side walls which define a storage chamber having a charging opening for the particulate material, and the side walls converge to form a discharge outlet for dispensing the particulate material. A pulsating diaphragm assembly including, an elastomeric member on the inner wall of the storage chamber, and pump means for causing the elastomeric member to expand the deflate. A transverse shelf or surface adjacent the discharge outlet can be provided for delivering the particulate material to a point of use. Bleed means can also be provided to bleed air from the pulsating diaphragm assembly in the event that pulsations terminate when the diaphragm assembly is in the expanded condition.

Abstract: The method of transporting an electrostatic strip wherein the strip on a supply roll is pulled from the supply roll which is normally freely rotatable and the strip having been pulled from the supply roll is returnable to the supply roll by driving the supply roll in reverse to rewind the electrostatic strip; the unspooling of the electrostatic strip from the supply roll is performed by a pair of feed rollers; after imaging the electrostatic strip, it is carried between a pair of longitudinally ribbed guides past a magnetic toner to an inspection station at which station it may be viewed and optionally severed from the remainder of the electrostatic strip, which remainder is returned toward the supply roll for neutralization, detoning, reimaging and refeeding to the viewing station, while the portion of the electrostatic strip at the viewing station is carried in a generally horizontal planar course to a fuser for making permanent the toned, unfused electrostatic image.

Abstract: A leader pin to securely hold the leading end of a strip for high speed unwinding wherein the end of a strip is inserted in a slot in a body and a keeper is inserted in the body embraced by the end of the strip; the keeper is provided with a resilient latch that is engageable with a channel on the body whereby the body and the keeper are strongly engaged together.

Abstract: A xerographic copier machine capable of producing copies of an original document in a selectable magnification ratio. The machine includes an object mirror and a light source forming a scanning assembly which travels at a uniform velocity under a transparent platen on which the document to be copied is placed, face down. The object mirror reflects the illuminated image of the document toward a relay mirror moving in the same direction but at half the scan velocity, the relay mirror directing the image toward a stationary projection lens, behind which is a reflex mirror. The reflex mirror re-directs the image through the lens onto an image mirror which casts the image onto the photoreceptor surface of a rotating drum. The peripheral velocity of the drum is synchronized with the scan velocity of the scan assembly by an adjustable transmission whereby a latent image of the entire document is formed in the photoreceptor surface.

Abstract: Apparatus for the elimination of noxious ammonia fumes associated with diazo copiers includes a plenum chamber disposed about the output aperture of the machine developer chamber. Vacuum means are provided to draw the ammonia laden air out of this chamber. Preferably this apparatus is used in conjunction with a novel filter connected between the chamber and the vacuum means. The filter comprises a filter body of a material such as corrugated paper having a plurality of longitudinal substantially parallel channels, the walls of which are impregnated with a material, such as phosphoric acid, which will react with ammonia to generate odorless end products. A granular layer impregnated with such a material may be disposed in contact with the output end of this filter body.
