Abstract: A hose clamp machine includes a frame carrying a reciprocating air motor, the piston shaft of which is coupled to one end of a lever which is pivoted approximately midway between the ends thereof on the frame, the other end of the lever being coupled by linkage to a band puller housing for slidably reciprocating it along a slide rod. A hose with a hose clamp band looped thereabout is mounted beneath the distal end of the slide rod with the free end of the band fed through a ratchet-type holding dog to a pulling dog in the puller housing. Pivotal movement of the lever during a driving stroke of the motor pulls the puller housing to tension the band, after which a punch head is driven into the band collar to lock the clamp in the tensioned condition about the hose. Cushioning means is provided on the piston shaft to cushion the driving stroke when the band is severed while under tension.

Abstract: A hair trimming head for slow rate hair trimming and thinning having a stationary blade with cutting teeth and a movable blade with cutting teeth, the blades being mounted in effective cutting relation with the teeth of the movable blade projecting beyond the ends of the teeth on the stationary blade, whereby hair first engages the teeth of the movable blade and is agitated and fed in controlled manner between the movable teeth into cutting engagement with the teeth of the stationary blade.The relative longitudinal positioning of the two blades is non-critical, it being necessary only to position the blades such that the effective cutting lengths of the teeth on the stationary blade lie within the limits of the effective cutting lengths of the teeth of the movable blade. The effective cutting length of the teeth of the stationary blade is of the order of about one or two times the diameter of human hair, thereby providing control over the amount of hair cut so overcutting and uneveness are avoided.

Abstract: A fastener for mounting on a post to hold barbed wire in which an elongated member has an eye at one end and mounting means at the other end, the eye defines an enlarged opening for free movement of barbed wire therethrough and the fastener includes means for positioning the eye a predetermined distance from the associated post. Two embodiments are disclosed, one having a single shank with an open enlarged eye and a positioning washer. After barbed wire is positioned in the open enlarged eye, the eye is manually closed to trap the wire. The second embodiment is a staple for use with wood posts in which two prongs are provided with a reverse bend between an eye and the prongs, thereby limiting the distance that the fastener can be driven into the wood post to position the eye a predetermined distance from the post.

Abstract: A target game wherein a missile having an end thereof provided with filamentary hook-like material of the type manufactured by the Velcro Corporation in conjunction with an open weave netting having openings in the range between of about 1/2 millimeter and 3 millimeters. Target representations each consisting of a solid member having indicia thereon, are positioned with the netting intermediate the representations and the missile thrower. When the missile having only the Velcro hooking elements thereon strikes the net, the net traps the missile to indicate the relative position of the missile and the target representations. The netting is such that it is easy to see the target representations therethrough.

Abstract: A memory device stores signals representative of a predetermined number of words constituting a given code. When and only when all the words have been received, a release signal causes the stored signals to be released to a device that displays or otherwise furnishes the information contained in the code. If more or less than the predetermined number of words is received by the decoder, a release signal is not generated.

Abstract: A device for distributing fluid from an inlet to an outlet, in which a series of plates in stack configuration provides a continuously subdividing fluid flow path between the inlet and the outlet such that the fluid distribution at the outlet is over a substantially greater area than the fluid at the inlet. Each plate in the stack of plates is provided with a plurality of apertures which in stack configuration define a plurality of fluid flow paths symmetrically about the axis of the fluid inlet.

Abstract: A mass transfer device consists of a stack of alternating plates and membranes in which each plate includes on each surface two manifolds for distributing and collecting fluid transversely of the plate. Headers interconnect the stack with the plate manifold fluid inlets and outlets to distribute and collect fluid uniformly to and from each plate. Inlet and outlet manifold channels of each plate surface are connected by channels formed in the central portion of the plate. Mass transfer occurs across the membrane supported between adjacent plates with a first fluid on one side and a second fluid on the other side. Substantially uniform inter- and intra- plate fluid distribution and thin fluid films enhance mass transfer. The device, with slight alterations appropriate to the application, is useful for dialysis, hemodialysis, blood oxygenation, reverse osmosis, heat exchange, or gas scrubbing.
