Abstract: A truck body has at least one vertical, longitudinal divider forming two compartments. Separate chutes are located on the top of the body, one communicating with each compartment so that one particular type of refuse (e.g., paper, aluminum cans and glass) may be dumped into a specific chute to fall by gravity into a compartment. The body may be tilted to shift all refuse to the rear. Each type refuse is discharged through a separate door at the rear. Bins are lifted vertically by hydraulic means to the top of the body and then tilted to dump into chutes. The bins are tucked under the body during transportation to reduce overall width. Further, the bins fan outward to facilitate loading. Wheeled carts filled with refuse may be hooked to the upper edges of the bins so that the carts and bins may be tilted at the upper end of their travel to dump into the chutes.

Abstract: Apparatus is used with two binding strips, the first having at least four studs projecting therefrom which are flexible and the second having holes complementary to the studs and for each hole a groove extending therefrom toward the center of the second strip. The apparatus moves to a position aligned with holes in a stack of sheets. The second strip is deposited on top of the stack with the holes thereof aligned with the holes in the sheets. The first strip is then raised so that the studs pass through the holes in the sheets and the second strip and pressure is applied forcing the strips toward each other. Blocks then move transversely, bending down the portions of the studs projecting beyond the second strip and snapping these portions into the grooves. The steps are performed sequentially using a single pneumatic cylinder for all but the first-mentioned step.

Abstract: Supplies used with the machine include sheets with holes at intervals, first plastic strips having flexible studs at the same intervals and second strips having holes at the same intervals. The outside surface of said second strip is formed with grooves to receive the bent excess lengths of the studs. The machine has a platen supporting the sheets and a bridge supporting the second strip. The first strip is installed with the studs through the holes in the sheets and second strip. A rotating cam shaft first pulls a pressure bar against the top of the first strip to compress the sheets between the strips with a pre-determined pressure. Mounted on the cam shaft is a drum cam having a pair of grooves which receive cam followers extending from horizontally reciprocating carriages. Each carriage has a pair of bending rollers which have a path of movement immediately below the bottom surface of the second strip.

Abstract: Commercially available battery-powered screwdriver output shafts are round and have hexagonal bores to receive the hexagonal shanks of screwdriver blades. An adapter has one end shaped to receive and engage such an output shaft. The opposite end is externally threaded to receive an internally threaded chuck which holds round shank twist drills. Thus, a power screwdriver may be used as a drill. An optional second adapter having one end shaped hexagonal to receive the screwdriver output shaft and be held in place by a set screw and has its opposite end shaped to be permanently attached to the first-mentioned adapter. This facilitates attaching and detaching the chuck.

Abstract: A mask protects doctors, dentists and technicians, on the one hand, and their patients, on the other, from cross-contamination with various viruses and germs. The mask is inexpensive and hence disposable after a single use, if desired. Various types of visors fit on the head of the wearer. Fixed to the forward projecting edge of the visor is a shield which extends down to protect the eyes, nose and mouth and around the sides. The shield may be attached to the edge of the visor by adhesives such as glue, heat sealing, ultrasonic welding or other suitable means.

Abstract: The apparatus is the justifying station of an automatic bookbinding machine which stages collection of the sheets of the book, justifies the side and end edges of the sheets, feeds male and female plastic bookbinding strips one at a time from cassettes, assembles the sheets and strips and then binds the book. In the sheet justifying apparatus the sheets are deposited on an originally horizontal movable jaw. The latter is then raised toward a stationary jaw until the sheets are loosely clamped. Thereupon the jaws with sheets therebetween are pivotted to vertical position. A first side guide is caused to reciprocate rapidly against one side edge of the stack of shets, justifying the opposite edge against a stationary guide on the opposite side edge. Simultaneously, a front edge of the stack, justifying the rear edge against a stationary base plate.

Abstract: A mask to protect physicians, dentists and technicians from spatter from patients afflicted with various diseases (including A.I.D.S.) is assembled from two parts, which may be shipped and stored flat. The visor is formed of a flat piece of sheet rubber formed with transverse slits so that the visor may be attached to ordinary eyeglasses. The shape of the visor provides a curved, forward extending bill. Slits are formed near the outer edge of the visor. A transparent shield has dovetail projections on its upper edge which snap through the slits. Other cooperating fastening means may be used to assemble the visor and shield and also to hold the visor on eyeglasses. The shield is supported by the visor and hangs down to about the chin, protecting the eyes, nose and mouth.

Abstract: A crucible contains a metal to be evaporated by heating from an electron beam source wherein the path of the electrons is controlled by a horizontal transverse magnetic field over the source and crucible. A number of small individual magnets are arranged horizontally along opposite sides of the crucible parallel to the beam path. The inner end of each magnet is in the closest position possible to deliver its flux lines to the magnetic field area. By varying the positions of the magnets, the field generated may be controlled in the desired manner.

Abstract: A holder for radiographic film fits between the jaws; the patient secures the holder steady by biting down thereon. The holder is U-shaped to provide space for root canal files which otherwise prevent the patient from biting down on conventional film holders. The holder accommodates placement of the film in horizontal or vertical direction and also for such placement while filming either jaw. Separate U-shaped holders may be used for anterior and posterior positions and separate posterior holders for the left and right jaws. By inverting the right lower posterior holder, it may be used on the upper left.

Abstract: A snap-on, tamper evident plastic cap for a plastic bottle neck has a skirt with upper and lower internal locking beads which lock under extenral beads on the neck. The cap is not removable so long as the skirt is intact. The lower end of the skirt, including the lower bead, may be torn off to permit the cap to be removed. To facilitate removal, the cap skirt is formed with a score line which slants upward from the lower edge of the skirt to merge with a circumferential score line which terminates near the origin of the slanted score line. A third score line extends from the terminus of the circumferential score line down to the lower edge of the skirt. Thus there is a tab (a remnant of the original skirt) between the first and third score lines which functions as a lift tab.

Abstract: Male and female book binding strips are packaged in cassettes and the respective cassettes are stacked in male and female hopper stations. Punched sheets are deposited in a staging station. The components of the book are then assembled in an assembly station. Thus the stack of sheets is fed onto one jaw and one male strip is fed onto that jaw while a female strip is fed onto the opposite jaw superimposed above the first-mentioned jaw. The two jaws are moved toward each other until the stack is loosely held therebetween. Thereupon the jaws are pivoted to vertical position, the stack resting on a base plate attached to one one jaw. The stack is jogged so that the holes in the sheets are aligned with each other and with the holes in the female strip. The male strip is pushed inward toward the stack, the studs fitting through the holes in the sheets and through the female strip.

Abstract: An improvement upon other inventions of Applicant wherein a visor which is attached to the head of the user supports a shield which hangs in front of the face of the wearer, protecting the eyes, nose and mouth from contamination which might be carried by dental and medical patients or in other environments. This invention differs in that the support of the shield is accomplished by forward extending tabs on the forward edge of the visor projecting into slots formed near the upper edge of the shield.

Abstract: A bale of compressed garbage and other refuse is formed in a stationary baling chamber by compressing successive charges of refuse against an inclined discharge gate by means of a multi-stage hydraulic ram having a platen or specific shape. The bale thus has a rectangular transverse cross-section having parallel sides and parallel top and bottom, a forward end upwardly-rearwardly inclined at about 15.degree. from the vertical and a rearward end having a vertical lower stretch extending upward from the bottom about half the height of the bale, an upwardly-forwardly inclined stretch at about 42.degree. to the horizontal above the lower stretch and a short vertical stretch above the inclined stretch.

Abstract: 5-gallon plastic molded bottles of at least two manufacturers have neck profiles which differ slightly but have a diameter where the variation in profile is at a minimum. The cap of this invention fits at least two profiles. In each profile there is an outward-convex bead below the top lip. The interior of the skirt of the cap curves concave approximately co-extensive with such bead curvature and has plural circumferential internal annular ridges which engage the bead at about its maximum diameter. Below the ridges is an internal annular tension ring having a diameter when unstressed less than the diameter of the top neck bead at its circle of contact which engages below the maximum bead diameter and hence tends to pull the ridges down into tighter engagement with the profiles of either manufacturers' neck finish. Below the tension ring the skirt is formed with a horizontal tear line which extends about 265.degree. of the circumference of the skirt.

Abstract: A woven cable has plural signal conductors, a pair of ground conductors for each signal conductor (one on each side thereof) and spacer fibers between adjacent conductors, the separation created by the spacer fibers determining the impedance between conductors. The foregoing all extend in the warp direction. The warp conductors are interwoven with weft fibers in such manner that each signal conductor and the ground conductors on either side thereof at all times are simultaneously above or below a particular weft fiber. Cross-talk is materially reduced, capacitance is more consistent, velocity of propagation is increased, signal loss is reduced, and rise time is lowered thereby.

Abstract: A web of flat plastic bag stock formed with transverse perforations and heat seals is separated into individual bags, then individually formed in plural folds and the folded bags are stacked for packaging. To form as many as three folds, four rollers are used. The individual, separated bag is forced between the first and second rolls by a reciprocating first "blade" which contacts the middle of the bag. After being formed with the first fold, the bag is forced between the second and third rolls by a reciprocating second "blade". The twice-folded bag is then forced between the third and fourth rolls by a third reciprocating "blade" and, after the third fold, is conveyed away on belts to a stacking station where plural bags are deposited as a layer on a table. The layers may be packaged by hand or by suitable machinery.

Abstract: One or more horizontally disposed, vertically spaced raceways have passageways for medical gases and electrical wiring which may communicate with a vertical chase at the ends of the raceways which contain conduits for such gases and wiring. The gases are piped inside a compartment at the top of the raceway and then by branch pipes to outlets on the front or the bottom of the raceway. Wiring of different voltages are contained in vertically spaced passageways in the back of the raceway and are electrically connected to socket outlets at convenient intervals on the front. Vertical separators isolate the various voltage wires from each other. Detachable covers provide access to the various compartments. Rails are formed on the exterior so that auxiliary eqipment may be clamped thereto at desired intervals.
