Abstract: A metal nut (N) is held by a plastic clip-body (12). The clip-body (12) has first and second arms (16, 18) and an end wall (20) that form a closed end and an open end (6). The open end (60) includes cam surfaces for camming a member (M) into the open end (60). It also includes an annular locator wall (28) that extends upwardly from the second arm (18). The upper end of this locator wall is formed to slope upwardly as it extends inwardly from the open end of the clip-body (12). The sloping upper end of the locator wall (28) helps to cam the member (M) into the clip-body (12). The clip-body (12) includes a first arm (16) having sidewalls (36, 38) that extend outwardly from the arm (16).

Abstract: A plurality of hold-down bearings (12) are locked into position on longitudinal guide beams (12, 12?). Anti-splash bearings (10) are positioned on the guide beams (12, 12?) longitudinally between the hold-down bearings (12). The anti-splash bearings have bottom flaps (46, 48) which contact bottom flanges (36, 38) on the floor slats (20) and block the upward flow of water into the region below the conveyor slats (20). The hold-down bearings (20) also block to a considerable extent the upward movement of water into the underneath regions of the conveyor slats (20).

Abstract: The fundamental technique of the method for making cellular cores is to make stacks of components which are configured such that cutting slices off the stacks produces cellular cores and, when needed, components used in stacks used to produce cellular cores. One of the basic components used in the stacks is termed a ribbed ply which is a ply (thin sheet of material such as wood) with a number of ribs (long thin strips of material such as wood) attached to the ply, parallel to each other. If the spaces between the ribs are filled with filler material such as foam plastic, the cells in the cellular core will be filled with the filler material. The filler material is introduced as layers of the material stacked alternately with plies and adhesively attached. Slices of such a stack, sliced parallel to the grain of the plies (if wood) are called ribbed fillers. Stacking ribbed fillers and plies produces a stack having a cross section which, when sliced, produces filled cell cellular cores.

Abstract: A screen frame (24) is detachably connected to a support frame structure (22, 124, 134) by locator pins (46, 118) and locator pin sockets (56, 112, 136). An elongated support arm (26) supports either a light box (34) or a work piece support (36) in a proper position relative to the print frame (24). The light box (34) and the work piece support (36) are interchangeable on the support arm (26).

Abstract: A vertical stabilizer (38) is supported by and projects upwardly and rearwardly from the tail portion (14) of a helicopter fuselage (12). A tail rotor (TSR) is mounted on the vertical stabilizer (38) for rotation about a horizontal axis (C). The tail rotor (TSR) is positioned laterally outwardly from one side of the vertical stabilizer (38). The vertical stabilizer (38) has an upper end, a lower end and a rear edge recess (44) located between the upper end and the lower end. The recess (44) has a laterally convex rear edge (50). The tail portion (14) of fuselage (12) has a rear end extension (40) that extends rearwardly from the vertical stabilizer (38) and narrows in width as it extends rearwardly. The rear end extension (40) of the fuselage (12) provides vertical area to replace vertical area that was removed by placement of the recess (44) in the vertical stabilizer (38).

Passageway (36) is connected to the opposite end of the valve spool chamber (26). The valve spool (50) has two positions. In the first position, passageway (32) is connected with a passageway (40) that extends to an air-operated device (44). Flow through the valve (24) to and from passageway (36) is blocked. In the second position, flow from passageway (32) to passageway (40) is blocked. Also, flow through the valve (24) to and from passageway (36) is blocked.

Abstract: An improved table and ink wipe cartridge for a pad printer consists of a table mounted to a base by a pair of parallel, nylon bearings. The bearings enable the table to slide back and forth easily without requiring conventional ballbearings and guides. The cartridge automatically rolls and wipes ink on a print tray carried by the table.

Abstract: A wall structure of a trailer box (10) is constructed from a plurality of panels (36, 38, 40) which are welded together where their edges meet. The panels (36, 38, 40) are each extrusions and each includes thin side skins (42, 44) and thin webs (46, 48, 50). The edge regions that are connected together include thickened portions that dissipate a substantial amount of the heat provided by the welds (56, 58). A plurality of panels (36, 38, 40) are welded together to form a large wall structure (WS). This wall structure (WS) is then reconfigured by a roll-forming machine (FIGS. 8-10) to provide a box (10) having a longitudinally straight and laterally curved configuration. Laterally considered, the box (10) has a concave inner side and a convex outer side. This shape of the box provides the box with both sidewalls and a bottom. The overall construction of the trailer box is lightweight and quite strong and facilitates construction of the truck/trailer box.

Abstract: A plurality of studs (14) are spaced apart relative to each other. Upper end portions (32) of the studs fit into an upper channel space (22) and lower end portions (34) fit into a lower channel space (30). The lower channel space (30) is defined in part by a pair of spaced apart sidewalls (24, 26). Screw fasteners (52) extend through the sidewalls (24, 26) and connect them to the lower end portion (34) of the stud (14). The studs (14) have upper ends that are spaced from a web (20) forming the upper boundary of the upper channel space (22). Vertical elongated slots (48, 50) are provided in the sidewalls (38, 40) of the studs (14). Screw fasteners extend through the sidewalls (16, 18) of the upper channel member (10) and then extend into and through the slots (48, 50). The heads of the screw fasteners (52) bear against the sidewalls (16, 18) when the screw fasteners (52) are tightened.

Abstract: Sodium ortho-phenylphenate is admixed with water to produce a process water for treating produce. Potassium carbonate is admixed with the process water in an amount necessary to necessary to raise the specific gravity of the process water to a level whereat it will float fruits and vegetables that would otherwise tend to sink in the process water. When a chlorine-based biocide is used in the process water potassium bicarbonate is used to provide the desired specific gravity of the process water. Over time, used process water is cleaned by settling, by use of a filter, or by use of some other mechanical separating equipment, and the cleaned process water is recycled.

Abstract: A reciprocating slat conveyor is composed of laterally spaced apart movable conveyor slats (10) and fix conveyor slats (12) laterally between the movable slats (10). The movable slats (10) are clamped to transverse drive beams (56) by clamp structure that includes an upper clamp member (62) and a lower clamp surface (70) carried by the transverse drive beam (56). Bottom flanges (66, 68) on channel members (60) are clamped between the clamp member (72) and the clamp surface (70). The channel member (60) is connected to a central portion (32) depending from the movable slat top wall (14, 16). Portions (30, 32) carry bottom members (34) having side portions (36, 38). The side portions (36, 38) are in contact with lower bearing surfaces (42, 44). The top wall members (14, 16) of the conveyor slats (10) rest on the upper portions of the bearings (28, 30). An apron (84) extends laterally across the rear end portion of the conveyor.

Abstract: A foam body is made in the form if the letter “M”. Side portions of the foam body include confronting, temple engaging, inside surfaces, spaced apart a distance less than the temple—temple width of a person's head. The foam body is constructed from a springable form that stores spring energy when bent and allows the side portions to be sprung apart, and when released to move back towards each other. The side portions of the form body are sprung apart and a person places his/her head between the side portions. Then the side portions are released so that they will spring back towards their static positions and clamp onto the person's head, so as to secure the letter “M” display onto the person's head.

Abstract: An elongated tubular support (10) is mounted in a stationary position (FIGS. 6 and 7) for rotation about a horizontal (FIGS. 1 and 2) or vertical (FIG. 5) axis. A spring biased detent (66, 70, 72) is positioned between the support member (10) and a stationary mounting member (68). The detent (66, 70, 72) permits the display panel (DP) to be swung in position about a first position (FIG. 1) and a second position in which it is positioned about 180 degrees from the first position (FIG. 2).

Each upper conveyor slat (10) has a crown and opposite side portions that slope laterally outwardly and downwardly from the crown. The side portions have lower surfaces. A plurality of laterally spaced apart, longitudinally extending, V-shaped lower conveyor slats (12) are provided. These lower conveyor slats (12) are positioned between the upper conveyor slats (10). Each lower conveyor slats includes a valley and side portions that slope laterally outwardly and upwardly from the valley. The side portions have upper and lower surfaces. The side portions of the upper conveyor slats (10) overhang the side portions of the lower conveyor slats (12). A plurality of slide bearings (14) are positioned vertically between the upper and lower conveyor slats (10, 12) where the side portions of the upper conveyor slats (10) overhang side portions of the lower conveyor slats (12).

Abstract: An inner frame (38) is provided with a printing screen that includes a stencil of a numeral. An object to be printed (e.g. a shirt) is placed on a platen (P), in a substantially centered position with respect to an outer frame (10) having an open center (28). The inner frame (38) is positioned within the inner space (28) of the outer frame (10) and is fixed in position relative to the outer frame (10) so as to properly position the stencil with the object to be printed on the platen (P). Locator pins (82,84,86,88,90) and locator pin openings (92,94,96,98,100,102,104) are provided and arranged for establishing five possible positions of the inner frame (38) within the inner space (28) of the outer frame (10).

Abstract: A brush for cleaning corrugated surfaces has a multiplicity of bristles extending across the width of an elongated body. The bottom ends of the bristles form a virtual surface complementary to the corrugated surface. The bristles include a first set of bristles positioned to engage the ridges of the corrugated surface and a second set of bristles positioned to extend into the grooves of the corrugated surface. The first set of bristles have a first hardness, and the second set of bristles have a second hardness harder than the first hardness. This provides greater cleaning action in the hard to clean bottom surface portions of the grooves.

Abstract: A sodium chlorite solution is admixed with a second solution containing an acid to make a reacted mixture. The reacted mixture is introduced into a water system, viz. a conduit in which water flows or a tank containing water. The reacted mixture is added to the water system to inhibit and/or eliminate bacterial fouling in the system, and/or inhibiting and/or removing mineral deposits from the system, and/or for reducing or eliminating microorganisms from the system. The second component is acidic enough to convert the sodium chlorite into chlorine dioxide while remaining unaffected in the reacted mixture and at the same time being a mineral antiscalant. Optimum conversion of the sodium chlorite component into active chlorine dioxide requires at least several minutes reaction time and, preferably, the use of a suitable catalyst, such as sodium molybdate.

Abstract: A cutting blade (58) is secured to the lower end of a flexible drive shaft (18). Drive shaft (18) extends from the blade (58) upwardly through a tubular handle (12).The upper end of the drive shaft (18) is connected to the output of a drive motor (14). The cutting blade (58) is within a housing (10) having a bottom opening (64) and three lower side openings (72, 74, 76). A cutting blade (58) includes a pair of section vanes (104) which when the cutting blade 58) is rotating serve to pull air into the housing (10) through the lower sidewall openings (72, 74, 76). The moving air picks up the cuttings and moves them rearwardly into a cuttings bag (92) which is connected to and supported from a rear portion of the housing (10).

Abstract: Liquid candy is molded into a body of hard candy HC with a tubular portion 24 of a holder 22, 24 anchored therein. The tubular portion 22 extends into close proximity to an outer surface of the hardened candy HC. A cup-shaped portion 22 of the holder is snapped onto a reservoir cap 70. The holder 22, 24 is snapped into a fully engaged position. When a consumer wishes to consume the candy product, the consumer pulls up on the holder 22, 24 to move it upwardly relative to the reservoir cap into a second engaged position. A break-away portion 74 of the cap 70 breaks away to open fluid communication between the reservoir 62 and a passageway 36 through the holder 22, 24.
