Abstract: A fixture for precisely locating the vertical reinforcing steel bars in a hollow block wall at the exact positions specified by the design engineer. The fixture comprises one or more steel wires forming a horizontal supporting structure that is adapted to be laid on the top surfaces of the blocks at various levels as the blocks are being laid. In the preferred form, the horizontal supporting structure is a ladder-like structure made up of two laterally spaced, parallel wires connected together at intervals by cross wires. Certain of the cross wires have circular rings formed therein or attached thereto, and all of the cross wires have downwardly projecting legs that extend down into the cavities of the hollow blocks and engage the inner surfaces thereof to locate the ladder-like structure with respect to the blocks.

Abstract: A process for continuously producing dried protein concentrates, namely blood meal, from an aqueous solution of animal blood, in which the solution is atomized in superheated steam at a temperature of about 400.degree. C. The atomization of the solution is accomplished, at least in part, by a centrifugal atomizer that throws the solution radially outward in an extremely thin layer of finely divided droplets having diameters less than 100 microns. The small droplets pass into the stream of superheated steam, which causes the liquid to evaporate, and the dried blood solids to precipitate to the bottom of the collector where they are discharged by a conveyor. The superheated steam, which was cooled to about 200.degree. C. by the drying process, goes to a cyclone separator which removes any entrained solids, and is then returned to the heat exchanger, where it is again heated to about 400.degree. C. for re-use in the process.

Abstract: A 35mm film cartridge in which the link between the core of the cartridge and the film to be contained in the cartridge is an elongated trailer made of one-sided adhesive tape doubled up around the core of the cartridge and adhesive sides together, to the free ends of which trailer is attached between its adhesive sides the end of the film for a short length of approximately 15mm, and which trailer is cross-perforated to form a break-off tip containing the attached film, and which trailer further has its adhesive sides separated by backing or non-stick liner for another similar short length adjoining the cross-perforation. The width of the trailer is slightly less than the width of the film so as to cover the double perforation of the film, and the material of the trailer can be paper or another suitable material, and the trailer extends to a length of approximately 75mm when fully pulled out.

Abstract: A safety filler for underloaded firearm cartridges, in which the volume of powder is less than the volumetric capacity of the powder chamber. The filler comprises a sleeve that is inserted into the powder chamber, which radially reduces the typical interior volume of a cartridge shell so that a lesser amount of powder charge fills the remaining space to about 90% of its available capacity. Being preferably made of a flexible and resilient material, the filler sleeve can be inserted into a cartridge shell having a necked-down configuration. The specific configuration of the filler sleeve provides for a reduced volume powder chamber within the cartridge to allow an even distribution of the powder which will burn evenly and uniformly, allowing safe firing of the bullet.

Abstract: An adjustable connection between a ski and its binding, comprising an elevated platform that is attached to the ski at two longitudinally spaced points by supports that allow the ski to flex between the supports. Mounted on top of the elevated platform is a boot plate, to which the ski binding is attached. The boot plate is attached to the platform by screw connections that allow for rotation of the boot plate about a vertical axis, or for translation in the fore-and-aft or lateral directions. The supports, in one form of the invention, are individually adjustable in length so that the platform can be tilted laterally with respect to the top surface of the ski, or tilted longitudinally, or raised and lowered while maintaining parallelism with respect to the ski. Thus, the invention allows for rotational adjustment about any one or all 3 mutually perpendicular axes, as well as translational adjustment in all 3 planes, all without removing the ski bindings from the platform, or the platform from the ski.

Abstract: An electrically powered tethered model airplane connected to a central post or pylon. The tether line is also the electrical wire to supply power to an electric motor in the airplane that drives the propeller. The airplane assembly typically has two airplanes connected to the central pylon. A unique connection arrangement at the interface of the tether lines and the central pylon allows not only for electrical contact, but also for circular movement of the tether lines and planes around the pylon without becoming wrapped or wound on the pylon. Two transformers are connected to the electrical connection at the top of the pylon, enabling two operators to control their respective airplanes for various maneuvers.

Abstract: A process and device for separating the liquid part from the solid part of seeds, fruit and/or plants, wherein the raw material is fed into a pressure vessel which is pressurized with gas selected in accordance with the properties of the material, the pressure in the vessel is suddenly released whereby the cells of the material are ruptured from the inside outwards by the equalizing of the pressure inside the cells on pressure release, the resultant disintegrated mash is then concentrated in a continuous leaching process with cold liquid, and after separating the unusable solids, the resultant liquid is subjected to appropriate aftertreatment for recovering the final product until the pure juice, oil or sugar has reached the required quality, the solid residue being either further processed or rejected.

Abstract: A solid, monolithic bicycle tire made of urethane rubber with a cured hardness of from 50 to 95 Durometer A. The tire is formed with a pair of laterally spaced bead shoulders that seat on the bead seats of the wheel rim, and has a circumferential, arch-shaped tunnel formed in the inner side of the tire between the bead shoulders. The tunnel co-operates with the channel in the bottom of the wheel rim to form an annular void, or air space, that allows the tire to collapse locally under excessive impact loads, and at the same time provides a space into which the solid urethane elastomer can be displaced under compression. Under normal riding conditions, most of the light shock loads experienced when riding on a relatively smooth road surface are absorbed by the resiliency of the urethane rubber, with only a minor amount of deflection of the arched tunnel. A severe impact causes the tunnel to collapse to a greater extent, thereby absorbing the shock load and preventing damage to the wheel rim.

Abstract: A take-up frame for pile fabric consisting of two suspension frames mounted on opposite ends of a cylindrical shaft, each frame comprising a plurality of angularly spaced arms projecting radially from a central hub. Each of the arms has a narrow slot formed in the side facing away from the other frame. The slot extends lengthwise of the arm and extends only part way through the thickness of the arm. A plurality of slot-like apertures extends through the remaining thickness of the arm from the bottom of the slot to the other side of the arm. The slot-like apertures are spaced apart equidistantly from one another along the length of the slot. Inserted into the slot is a hook band consisting of a plurality of hooks joined together and spaced apart from one another the same distance as the space between the slot-like apertures. Each of the hooks passes through its respective slot-like aperture and projects from the other side of the arm, where it is adapted to hook onto the edge of the pile fabric.

Abstract: A machine for laying down and taking up strips of artificial turf comprising a self-powered, highly maneuverable carrier having means for transporting, picking up and winding or unwinding a roll of turf strip. Means are provided to shift the roll axially relative to the carrier to precisely lay down each strip in side-by-side relation with a previously laid strip.

Abstract: Heat stabilization of polyurethane elastomer catalyzed with organo-metallic catalyst is accomplished by adding a minor amount of elemental sulfur or sulfur-donor material to the liquid mixture of polyol and organic polyisocyanate at the time the catalyst is added. The sulfur remains inert during the polymerization reaction, and as long as the temperature of the cured elastomer does not exceed about 200.degree. F. When the temperature of the urethane exceeds 200.degree. F, the sulfur reacts with the catalyst to form a metallic sulfide, which results in the complete neutralization, or deactivation of the catalyst. Elimination of the organo-metallic catalyst prevents depolymerization of the urethane, and the urethane therefore remains solid at high temperatures for much longer periods of time than has heretofore been possible. The amount of sulfur required to deactivate will depend upon the metal content of the organo-metallic catalyst.

Abstract: A telephone disabling device for preventing outgoing calls while permitting a two-way conversation includes a disabling member having a cover portion extending over the dialing device. The member is hooked under a forward part of the telephone and the rear end thereof extends between the laterally spaced uprights forming the hand set cradle. A key lock carried by the disabling member is extendible into a rearwardly opening cavity in the telephone to prevent removal of the member. A modified form of disabling device prevents both outgoing calls and two-way conversation.

Abstract: A method and apparatus for continuously monitoring and telemetering the condition of the vacuum pressure in the intake manifold of an automotive vehicle. The vacuum pressure is continuously sampled by a vacuum-pressure-sensitive device having one end that moves responsive to changes in the vacuum pressure. Mounted on the movable end of the device is a scanning arrangement that moves a pair of metal strips across the front of two light barrier devices as the pressure changes. In the preferred form, the two light barrier devices each consist of a photo-diode transmitter and a photo-transistor receiver. The output from the light barrier devices consists of an electrical signal having three stages as the pressure increases or decreases. The electrical signal passes through a switching arrangement which successively lights up three different-colored lights to inform the operator as to the condition of the vacuum in the intake manifold.

Abstract: A flexible terminator used as a terminal connector between the ends of a tether line and the ballast or a float for the construction of a tethered breakwater unit. One end of the terminator has a unique configuration which receives the end of the tether line in such a manner that the tether line is locked into attachment to the terminator without the use of a conventional knot arrangement. The terminator has a flexible central neck portion which receives the flexion between the floats and the ballast due to the wave motion in the water, eliminating the significant fatigue and normal fiber abrasion experienced by the tether line when tied to the ballast by a typical knot. The tether line is in axial alignment with the central neck portion of the terminator, so that the pendulum action at the attachment points between the tether line and the float and the ballast are transferred to the central portion of the terminator.

Abstract: Apparatus for filling a vehicle tire with a reactive liquid elastomer which when cured results in a flat-free tire. The apparatus provides for pre-filling the tire with air of desired pressure to properly set the tire bead on its rim and to maintain such tire pressure during the liquid filling operation. The apparatus enables removal of residual air within the tire as the tire is being filled with liquid and also indicates when the tire is completely filled with such liquid.
