Abstract: A novel end bracket for the ends of each of several wood cross bars that support the shelf decking in a storage rack, and a storage rack incorporating the same. The end bracket has a rigid main rectangular plate with a thin, flat, rigid supporting tongue extending rigidly outward from one side of the plate for a substantial distance beyond the cross bar end. A rigid flange extends downward from each end of the main rectangular plate for embracing the cross bar end. A rigid finger extends inward at the bottom of each of the flanges, at a slight obtuse angle to the flange, for confining the cross bar end. At least one rigid hook member extends inward at the bottom of each flange, with a rigid tapered tip oriented at an acute angle to the shank of the hook member, for fixedly securing the end bracket to the cross bar by driving the hook into the cross bar.

Abstract: A diffuser for dispersing gas into a body of liquid that may contain suspended solids. Under ordinary clogging conditions, the diffuser will remain operative over an indefinite period of time by reason of large gas outlet openings at the bottom of the gas plenum chamber. In addition, it can be employed for a good portion of that time to disperse a substantial flow of coarse bubbles and fine bubbles, in a desired combination, simultaneously from a single gas plenum. Careful selection of the permeability and area of a top porous wall of a gas plenum chamber, together with proper selection of the level, size and number of coarse bubble gas outlet openings in the side walls of the plenum chamber, achieve the second feature.

Abstract: A stove for burning wood, coal and other fuels comprised of flammable solids that among other things produce one or more flammable gases when heating or burning. The preferred form of the stove has three modes of operation--a rapid burning mode, a normal or medium burning mode and a banked mode. The user makes a preliminary decision as to whether the stove is to be operated in its normal mode or banked mode. Thereafter, controlled by temperature responsive means, the stove moves itself fully automatically back and forth from the rapid burning mode to whichever one of the other two modes of operation has been preselected by the user.

Abstract: A fluid diffuser for dispersing a gas or liquid into a body of receiving liquid in which it is immersed. The diffuser includes a rotatable shaft, a thin disk-like member mounted for rotation on the shaft, and an annular ring positioned adjacent the outer perimeter of the disk-like member. At least one of the top and bottom walls of the annular ring is porous. These top and bottom walls define a fluid plenum, into which gas or liquid under pressure is introduced to be emitted from the plenum as small, nascent fluid spheroids on the surface of the annular ring. The boundary layer flow from rotation of the disk-like member within the body of receiving liquid shears fine gas bubbles or liquid particles from the foraminous surface or surfaces of the annular ring. The annular ring may be fixed, or rotatable in the opposite annular direction from the rotation of the disk. Impeller blades may be mounted on the top and/or bottom surfaces of the rotatable disk.

Abstract: A T-shaped bolt for use in securing two slotted members--such as an upright post and a horizontal beam in a pallet storage rack--to each other. The tee head of the bolt is dimensioned to be inserted in a pair of aligned slots of the two members that are to be secured to each other, and then rotated so that the ends of the tee head abut edge portions of the slot in the first slotted member, with the threaded shank of the bolt extending out through the slot in the second slotted member. The nut to be threaded on the bolt is a torque resistant nut, and thus when it is first turned it will cause the bolt to rotate until its specially shaped neck abuts the edges of one or both slots. At this point, the application of a predetermined minimum torque causes the nut to be turned further upon the bolt, until it is turned up tight against the second member and secures the two slotted members to each other.

Abstract: A rotary loop taker, for use in a lock-stitch sewing machine, which has a detachable and replaceable hook or loop seizing point. A lug extending downwardly from the main body of the replaceable loop seizing point abuts one end wall of a cut-away portion of the annular frame of the rotary loop taker, and carries a foot that extends inwardly from the annular frame toward the rotatable shaft of the device. The inwardly extending lug foot desirably nests in a notch in the crosswise support member on which the annular frame of the rotary loop taker rests, preferably forming a snug fit with the upper surface of the crosswise support member. The preferable form and dimensions of the loop seizing point and the foot extending inwardly from the downwardly extending lug are disclosed. Ledges formed in the inner wall of the replaceable loop seizing point define the initial portion of the raceway for the bobbin case with which the rotary loop taker is used.

Abstract: A burglar alarm system of the non-wired perimeter protective type for detecting and indicating break-ins at an entrance or opening, such as a window or door, of a building, employs as a sonic signal generator a transducer that is both triggered and powered by the break-in. The sonic signal is of a specific selected supersonic frequency and is received by a remotely located local receiver within the building which in turn may actuate an alarm. Protection against false activation by sonic noise is provided by altering the gain of the receiver in response to received sonic noise adjacent to but different from the selected frequency, so that noise containing even a strong signal at the selected frequency, as well as at adjacent frequencies, does not result in an alarm being raised, but a weaker signal at the selected frequency, without signals at adjacent frequencies, such as is produced by the transducer, does result in an alarm being activated.

Abstract: A retarder device for applying gradually increasing braking force to a moving object such as a pallet rolling on a gravitationally actuated conveyor system. The device produces a three-stage application of braking force to the moving object as the object moves along its predetermined path and rolls over a brake wheel that actuates a gear train. The gear train comprises a plurality of intermeshed gears that progressively increases the angular velocity of the rotating gears as the first gear in the train is rotated. A fly wheel carrying at least one pivotally mounted fly weight, and preferably a plurality of weights equally spaced around the wheel, is fixedly secured to the terminal gear of the train. The inertia of the various members of the gear train, the fly wheel, and the fly weights applies the first stage braking force to the moving object.

Abstract: A stove for burning solid fuel such as firewood. a lower level air inlet opening is provided for so-called "primary air," and another air inlet opening is provided at a higher level for so-called "secondary air." The volume of air introduced into the stove from each inlet opening is separately controlled. An air metering means controls the amount of secondary air introduced into the stove through the higher level air inlet opening. The lower level air inlet opening and the air metering means both have a finite number of predetermined, fixed air transmitting conditions and no other air transmitting conditions. The lower level air inlet opening has preferably two predetermined, fixed air transmitting conditions--a maximum and a minimum. The air metering means has at least a predetermined, fixed maximum air transmitting condition and preferably also a predetermined, fixed minimum, transmitting condition. The level at which the two air inlet openings are located is specified.

Abstract: An easily and conveniently portable barbecue grill in which the bowl has an outwardly and upwardly extending flange around its perimeter and the lid has an outwardly extending flange around its perimeter, which flanges cooperate to produce a secure attachment between the lid and the bowl when the lid is placed on the bowl in a certain way. In the preferred embodiment, the bowl flange has two or more indentations equally spaced around its perimeter to form a number of inwardly facing reentrant portions on that flange, and the lid flange has at least one gap in its perimeter.

Abstract: A mixer for mixing a body of receiving liquid with solids, liquids or gases introduced therein. The mixer includes a rotatable shaft, a thin disk-like member mounted for rotation on the shaft, and at least one thin annular ring mounted on the disk-like member spaced from, parallel to and concentric with it. The flow of liquid perpendicular to the annular ring through the inner opening thereof, when the mixer is immersed and rotating in the body of receiving liquid, is unimpeded by any structural member. The annular ring may be mounted on either side of the disk, and a plurality of annular rings may be employed. The annular ring or rings may be mounted on the disk-like member by at least three elongated support posts spaced equally around the outer perimeter of the disk, the transverse cross-section of each post being curvilinear, preferably circular, in shape. The mixer is disclosed for use in a tank.

Abstract: A storage rack with spaced tolerance control tabs which effectively minimize down-aisle space buildup. The control tabs are positioned along the length of the storage rack and extend from the angles of the beam assemblies.

In the preferred form, each control tab is located generally midway along the upright edge of the angle from which it extends, is generally rectangular in shape, and has a length about 1/10 the length of the upright edge of the angle.

Abstract: A movable device for restraining freight in a cargo area in a freight transporting vehicle, for use with a track extending along the cargo area at the top side portions of the vehicle. The device includes an upright stanchion having a vertically extending cargo restraining surface on one side normal to the track. A carriage rolls along the track to permit moving the restraining device to a desired position, and locking pins secure the stanchion in that position. A yoke connects the carriage with the stanchion, to provide a support framework for the stanchion that is rigid throughout its entire extent, in the vertical plane that passes through the center of gravity of the stanchion and is normal to the track, from the rollers of the carriage, along the roller axle and any supporting structure, along the yoke member, and across the stanchion to the vertical plane that passes through the center of gravity of the stanchion and is parallel to the track.

Abstract: A shopping cart with a baby seat at the rear of the cart. The front wall of the seat, against which the infant or child leans, has an upright, closed position and an open position. The width of the baby seat front wall is less than the width of the main lading-carrying basket of the shopping cart, so that it can be swung down from its upright, closed position in the forward direction, when desired, to rest on the bottom wall of the basket to increase the capacity of the shopping cart by adding the space enclosed by the side and rear walls of the baby seat. A latch holds the baby seat front wall in its upright, closed position and preferably cooperates with a lost motion hinge at the bottom of the wall, and in its preferred form includes at least one cammed latch member that slides up across a ramp or slide member to (1) move the front wall upward as it approaches its closed position, and then (2) drop the front wall down to seat it in its closed position. The latch can be released by reversing this procedure.

Abstract: A replacement hasp for a railroad sliding door lock mechanism, a kit for making the hasp, and method for making the replacement using the kit are disclosed in two embodiments. The kit includes a member which partially defines an eye, sized to fit loosely about the existing hasp-retaining link on the car, and an eye-completion member arrayed to mate with the first member and form a replacement hasp when affixed thereto, as by welding with shear welds. In the first embodiment, the first member is generally U-shaped and the second member includes a tongue portion which mates between the ends of the partial-eye-defining member such that the two can be "telescoped" together to form a replacement hasp of different lengths to accommodate changes in the door or door jamb of the railroad car. The two main members include furrows extending along the parting lines between them so as to aid in welding the main members together and to form a stronger affixture than is possible under the prior commercial practice.

Abstract: A nuclear fission electrical generator for extracting electrical power from fissionable material having semi-conductor characteristics without the necessity of an intervening thermal energy. Unwanted, randomly created electron-hole pairs are depleted from the semiconductor material. Phthalocyanine semiconductor are suitable, and uranium phthalocyanine is particularly suitable for use in this invention.

Abstract: In the manufacture of mineral-wool mats or slabs, the raw materials are melted in a melting furnace and are spun to fibers in a spinner. The fibers, after admixture of a resin binder, are deposited so as to be formed to wool mats in a collecting chamber, then cured, trimmed at the sides and cut up into lengths. Both during spinning and during trimming, cutting up into lengths and a subsequent final inspection and check for defects, waste products arise. In order not to have to deliver these waste products, as hitherto, to a proper dump but, instead, to be able to recycle them direct to the production process, the waste products are broken up into smaller pieces and/or unravelled, heated and then briquetted while hot, whereupon the briquettes, possibly after cooling down and interim storage, are combined with the raw materials which are to be melted and thus returned via the melting furnace into the production process.

Abstract: A kettle cooker hinge which comprises two spaced legs joined by a bight section to form an inverted U-shaped member which has fully closed, partially opened and fully opened positions. A first mechanism is provided for pivotally securing the lower end of each of the legs to the inner wall of the kettle at opposite sides thereof. The locations of these first pivot mechanisms lie in a first pair of adjacent quadrants of the kettle. A second mechanism for pivotally securing the bight at the upper end of the inverted U-shaped member to the inner wall of the cover is provided at a location directly above the other two quadrants of the kettle when the cover and the inverted U-shaped member are in their closed positions. This second mechanism extends, for stability, on opposite sides of the vertical plane that divides the other two quadrants of the kettle. The bight lies outside the kettle when the inverted U-shaped member is in its fully opened position.

Abstract: A separable fastener device adapted for use in securing a removable foot support device to an internal portion of a shoe. The separable fastener device is comprised of two engaging elements.
