Abstract: An apparatus employs two spaced apart dipole magnets. An ion beam containing carbon of mass 2, 13 and 14 is focused by an Einzel lens and is directed into a first dipole magnet. The first magnet causes the beam to bend approximately 70 degrees, which separates the mass 12, 13 and 14 ions while at the same time focusing them in the X direction or deflection plane. The ions exit the first dipole magnet and pass through a blanking plate which can selectively remove one or two of the beams of mass 12, 13 and 14 ions. After leaving the first bending magnet, the mass 12 and 14 beams pass through a steering device so the trajectories of the mass 12 and 14 ions are deflected a few degrees to bring them parallel to the mass 13 ion beam. The parallel ion beams next pass through an electrostatic slot lens which focuses the beams in the direction out of the bending plane. After passing through the slot lens, the mass 12 and 14 beams are deflected in like amount to the deflection at the first steering device.

Abstract: The water is removed from food product pouches which have passed through a water bath by advancing the pouches in a continuous stream on a first tray which is vibrated with respect to a frame. The pouches are advanced beneath an air manifold which discharges air onto the pouch to blow moisture downwardly. An air outlet is formed in the tray beneath the air manifold, and air is drawn therethrough. The reduced pressure produced by the partial vacuum restrains the pouch from upstream motion, and serves to draw away the water which has been detached from the pouch. A second vibrating tray is positioned to receive pouches discharged from the first tray. An inclined ramp flips the pouches as they travel between the trays to present the underside of the pouch for drying. Once flipped the pouches progress along the second tray beneath a second air manifold and vacuum air outlet to complete the water removal prior to discharging the pouch from the apparatus.

Abstract: An interior wedge wire drum screen is mounted wholly within an exterior drum screen of narrower wedge wire spacing, and both are mounted to a frame and caused to rotate about a common central axis. One end of the outer drum is open and the other is closed by a disc-shaped drum head. The inner drum has an open end which is spaced inward of the open end of the outer drum. The waste water is presented to the surface of the inner drum screen by a waste water infeed which employs a vertical column. The column extends upwardly of an inlet and has a gradually increasing cross-section for reducing the flow of velocity of the waste water. A horizontal trough extends along the axis defined by the drums and communicates between the top of the column and a tray. The edges of the tray terminate in weirs which are parallel to the sides of the inner drum. Water flows in a smooth sheet over a weir to impact the sides of the inner screen with low velocity.

Abstract: A complete vehicle accident prevention system utilizing electromagnetic transmissions for the purpose of: 1) alerting drivers to the presence of certain unanticipated accident threats such as pedestrians, bicyclists, joggers, emergency vehicles, disabled vehicles, etc.; 2) alerting people using the roadway that a vehicle is approaching thereby inducing them to move to the side of the road. The system also utilizes a speaker assembly mounted on the vehicle to forwardly transmit a pre-programmed array of natural sounds having a frequency audible to the typical human ear for the purpose of inducing animals and people to vacate the path of the approaching vehicle. The controller may receive data from a radio direction finder to cause the display to indicate to the driver of the vehicle the relative position of a potential road hazard.

Abstract: A plastic looped handle has a front ring with two parallel members connected by a front brush head member. Bristles in curved rows extend from one side of the brush head for brushing of teeth, while convex protrusions extend from the other side of the brush head for tongue cleaning. A center bar extends across the front ring, and a rear ring extends rearwardly from the center bar. A front opening is defined between the front ring and the center bar and a rear opening is defined between the rear ring and the center bar. Both openings are sufficiently large to receive at least two human fingers therethrough. The center bar defines an angle with one of the front members of less than 90 degrees, to thereby define a wedge space, into which the hand of a user may be inserted and wedged to thereby retain control of the toothbrush.

Abstract: An embryo collection dish has a cylindrical sidewall with an inlet tube which communicates with an animal uterus from which the embryos are flushed. A lid is engaged with the dish and clamps a sheet of filter material therebetween. In use the filter is disposed vertically and the embryo cattier fluid is discharged from the device through an outlet tube which extends from the lid. The vertical distance between the inlet and outlet tubes is adjustable to control the volume of liquid retained in the dish along with the embryos. The dish together with its contents may be placed directly under a microscope for selection and extraction of the collected embryos. The device is sufficiently compact and fluid tight that it may be placed within a users clothing during collection to keep the embryos warm. Alternatively, an intermediate ring may be provided which joins a reusable lid to a disposable dish.

Abstract: Proofed dough is formed into pizza crusts which am formed and frozen without baking. The dough is positioned on corrugated paperboard preforms within a tray having multiple circular openings. The preforms have sidewardly opening corrugations. The trays are conveyed through the forming apparatus in a continuous process, with formed crusts being removed and fresh preforms being inserted. The preforms are positioned in a rectangular array within the openings in the conveyed tray. A quantity of raw dough is positioned on each preform within the tray. The dough is conveyed on the preforms beneath a bank of high pressure forming dies. The dies are pressed into the openings within the tray and over the dough to form the dough into the desired pizza crust shape. Each die extends between the preform and the tray within the opening to force portions of the dough into the preform corrugations to thereby secure the formed dough to the preform.

Abstract: A venetian blind assembly has a tilt drum support with a base which has a three-segment zig-zag type slot through which two ladder legs extend and are offset sidewardly from one another, with the tilt drum interposed from front to back between the two legs. The slot holds the ladder legs apart to insure non-overlapping winding of the joined ladder legs on the tilt drum. The tilt drum is connected to a flexible cable that turns and extends vertically downwardly on the window stile. The flexible cable is positioned by a plastic guide which is fastened to the stile. The flexible cable has an extruded fitting crimped to it which has a D-shaped opening in it. The fitting receives a vertical control rod which has a D-shape. The fitting opening is substantially deeper than is required to insure a proper connection with the vertical control rod. Hence the same vertical control rod may be installed on windows that vary in height by several inches, with the excess length absorbed within the fitting opening.

Abstract: A device for carrying articles, in particular bicycles, on the rear portion of a motor-vehicle, has three structures having respective hubs mounted on a splined shaft, so that each structure may be easily separated from the splined portion of the shaft and mounted again in a different angular position relative to the shaft.

Abstract: To assist in rapid taping of seams between adjacent drywall units, a tape is provided in rolls. The tape has a first layer of flexible paper material with an inwardly facing pressure-sensitive adhesive coating thereon. A second layer of reinforcing woven fiber material overlies the first layer. A third layer of flexible material overlies the woven fiber material to encapsulate the fiber material between the first layer and the second layer. The third layer has an outwardly facing release coating such that the first layer adhesive will releasably engage the third layer for manual separation of the tape when rolled upon itself. A crease is formed along the center of the tape to facilitate positioning of the tape in a wall corner. The self release properties of the tape allow it to be easily dispensed and applied without the need to remove a backing. The adhesive is formulated to maintain adhesion even when wetted by an overlying layer of drywall mud.

Abstract: A bicycling shoe has a ferromagnetic backing plate positionably connected to its sole. A nonmagnetic support plate has a plurality of through holes, and is fixed to the backing plate. NdFeB magnets of alternating polarity are attached by epoxy to the sidewalls of the through holes and make magnetic contact with the backing plate. A similar backing plate, support plate and alternating polarity magnet assembly is fixed to a bicycle pedal. A post extends from the pedal to position the shoe laterally. When the shoe is in a pedaling position, the polarity of the pedal magnets is opposite to the polarity of the shoe magnets, and the shoe is gripped to the pedal to permit transmission of power on the up stroke. To disengage, the shoe is rotated about the post, until like magnets are brought into opposition and the shoe is ejected from its position on the pedal.

Abstract: To provide convenient positioning of a subject in a wheelchair, the apparatus has a wheelchair support bucket with two wheel tubs which are connected by an axle. The wheelchair is pivotable in the bucket about the axle for tilting of the occupant. The axle is mounted to a frame which is elevatable on bearings, and the frame runs horizontally on tracks, and is rotatable. The bucket tubs have semi-cylindrical surfaces which position the wheelchair with the wheelchair brace frontward of the housing. The movement mechanism is thus able to be compactly positioned with respect the wheelchair, for convenient positioning of subjects for hair care, dentistry, or other operations. Tilt locks are provided on each bucket tub to passively prevent the egress of a wheelchair from an elevated or tilted bucket.

Abstract: The high voltage electrostatic accelerator of this invention has spark arrester rings which form magnetic shield elements around an acceleration tube and which together with mu-metal rings between accelerator segments shield the electrons being accelerated from stray static and dynamic magnetic fields. The spark arresters surround the accelerating electrodes. The rings between accelerator segments are formed of mu-metal, an alloy of nickel designed for its magnetic shielding properties and consisting of 77 percent nickel, 4.8 percent copper, 1.5 percent chrome and 14.9 percent iron. The mu-metal spark arresters together with the rings between accelerators segments provide an effective magnetic shield in a cost-effective manner. Because mu-metal has a high permeability, magnetic field lines tend to travel about the Mu-metal rings rather than pass through the acceleration tube, where they would influence electrons being accelerated.

Abstract: A cylindrical drum is rotatably mounted within a water tank. A water manifold is mounted to the exterior of the water tank and discharges chilled water through multiple axially spaced nozzles into the rotating drum within the tank to agitate the food product contained therein. The drum has a perforate skin which allows water to pass through but retains food product within. A helical auger is fixed to the drum and rotates with the drum to advance food product from the tank inlet to the tank outlet. The manifold discharges water on one side of the tank only, to impact food product as it is being lifted upwardly as the drum rotates. The drum may be provided with lifting baffles which further agitate the food product and cooperate with the agitating water injection to improve heat transfer from the food product.

Abstract: The paperback book of this invention has a book block with a plurality of sheets joined together at their spine edges. The book also has a stiff cover. A flattened woven tubular ribbon with tabs which is glued to the cover and the book block is glued to the ribbon. The tubular ribbon has tabs which extend continuously along the length of the ribbon and are 180 degrees apart on the outside circumference of the ribbon. The tabs thus divide the outside circumference of the ribbon into two regions. A first outside region of the ribbon is fastened by an adhesive to the inner spine portion of the cover and the surfaces of the tabs which extend from the first region are fastened by the adhesive to the inside surface of the cover adjacent to inner spine portion of the cover thus reinforcing the attachment of the cover to the spine. Adhesive also attaches the back of the book block at a second section of the outside circumference opposite the first section of the tubular ribbon.

Abstract: A clip for holding a downspout lateral in the tipped up position has a C-shaped body constructed of transparent, resilient plastic. The clip is resiliently snapped onto a downspout some distance above where a lateral joins the downspout. The C-shaped body of the clip has at least one depending lip for retaining the downspout lateral. The lateral is tilted upwardly until the upper edge of the lateral rests against the clip then the clip is slid down slightly until the lip engages the upper edge of the lateral and thereby retains it.

Abstract: An apparatus for removing the husks from ears of corn has axially extending rotatable molded rubber rolls. Each roll has a plurality of aligned axially extending flights which protrude from a cylindrical base segment. The flights may extend exclusively axially, or may extend circumferentially as well to define a segment of a helix. The flights of adjacent rolls are meshed with one another, and the rolls are rotated toward one another to engage husks therebetween. Portions of one or both rolls define a helical recess which extends the length of a roll. A continuous rib may extend from the base segment and is aligned between two flights and extends above the base segment, the rib extends through the helical recess, and engages husks within the recess of an adjacent roll. The continuous rib may be internally reinforced with a metal blade. The roll recesses provide relief for larger diameter trash and stalks, alleviating the flexing of the roll axles which might otherwise occur.
