Various techniques are disclosed for rotating the fluidized zone resulting from the interaction of the gas and liquid in the direction of the Coriolis rotational effect at the geographical point of use of the apparatus.

Abstract: A tooling utility system especially well suited for punches and dies employed in pharmaceutical tableting procedures is described. Punch trays, nesting one on top of another, have support rails with oppositely positioned arcuate cut-outs which provide nesting segments for securing the punches during transport and storage. Dies, placed within a cavity including a die support, are similarly secured in position. A substantial portion of the surface area of the punches and dies remain fully exposed, making for simplified inspection and cleaning procedures, including placing the vertically nesting trays directly into a sonic cleaner. The trays themselves form the outer structure of the tool system, secured together by hinged side covers or front and back snap on side covers. A unique tongue and groove interlocking arrangement is described which is disposed upon the top and bottom surfaces of the trays.

Abstract: A gun barrel cleaner is described for cleaning the bore of a pistol, rifle, or shotgun without danger of contaminating the breech area of the firearm. A cleaning rod is inserted from the nozzle of the gun extending into the breech area. Various structures are described for pivotal quick connection of interchangeable cleaning articles, such as brushes and oil swabs, to the end of the cleaning rod within the breech area. The cleaning article is pivoted into the breech area of the gun, and the rod pulled through the bore of the gun via the nozzle of the gun, preventing debris and/or oil contamination of the breech area of the gun. The procedure is then repeated as necessary utilizing different interchangeable cleaning articles as required. When clean, the cleaning article is replaced with a locking pin-locking tube combination secured by a padlock at the breech area of the gun with the cleaning rod in place within the barrel of the gun, visibly rendering accidental loading and discharge of the weapon impossible.

Abstract: A removable support structure for concrete slab fabrication is described. A latch device secured to the ends of both shoring girders and shoring beams permits rapid and accurate placement of the shoring support across a span to be structured in concrete. Vertical shoring posts and supports are eliminated, with the added advantage of the plane of the shoring always being automatically in the plane of the floor being formed. Bearing shoes on the ends of corrugated deck members, secured to building girders, cooperating with straps at their other ends, accurately and securely positions the corrugated decking in place. After the concrete has hardened, the entire support structure, including the shoring girders, shoring beams, and corrugated deck members, are rapidly and efficiently removed, ready for re-use.

Abstract: A method for producing composite, structural plastic parts in traditional foundry molds, including sand, permanent, die-cast, wax and investment molds. Short fiber length fibers reinforcing low viscosity thermoset resins, and in particular resole phenolics, provides a pourable low bulk density polymer compound with minimal externally applied thermal requirements during molding and post cure when required. Foundries can consider metal parts replacement with this new method. It permits foundries to actually produce composite, structural plastic parts with superior mechanical and thermal properties. This permits them to provide plastic products on a competitive basis with the compression and injection molders.

Abstract: A safety needle cap assembly for needles is described. In place of the usual safety cap which requires a doctor, dentist or nurse to manually place it in position on a used syringe needle, the safety needle cap assembly of the invention automatically caps the used needle the instant the needle is withdrawn from the patient. An elastic sheath or spring attached to a safety needle cap is kept under tension, retracting the cap and allowing the needle tip to be exposed. Once used and removed from the patient, the elastic tension is released, causing the safety needle cap to snap over the used needle tip automatically, without any operator assistance. The design of the safety needle cap assembly as described facilitates the utilization thereof, especially where it is important to distance the operator's fingers from the point of contact of the needle with the patient's body.

Abstract: A safety needle cap assembly for needles and catheters is described. In place of the usual safety cap which requires a doctor, dentist or nurse to manually place it in position on a used syringe needle, the safety needle cap assembly of the invention automatically caps the used needle the instant the needle is withdrawn from the patient. An elastic sheath or spring attached to a safety needle cap is kept under tension, retracting the cap and allowing the needle tip to be exposed. Once used and removed from the patient, the elastic tension is released, causing the safety needle cap to snap over the used needle tip automatically, without any operator assistance. The design of the safety needle cap assembly as described includes at least needle clogging material disposed in the safety needle cap to fill the tip of the needle therewith so as to entrap the fluid contained therein. This can be combined with needle capturing material to further enhance the safety features of the assembly.

Abstract: There is disclosed a device for measuring the magnetic field strengths associated with a.c. electrical currents over a protracted period of time and, as required, in hostile environments. A preferable application calls for the determination of the field strengths associated with electrical currents flowing in the a.c. power distribution lines of utilities. The device includes a monitoring instrument positioned in relation to the power lines to be monitored, typically at the base of a pole immediately adjacent the pole of the power line or on a power line supporting pole itself. In order to provide for long term, powering of the monitoring device, d.c. power is developed utilizing the a.c. power that is present. The conversion from a.c. to d.c. is effected at a distance sufficiently far from the monitoring instrument so as not to have any consequence on the readings that are being taken. Readings during the protracted period are typically stored and then accessable at pre-determined periods.

Abstract: A traffic safety control security system is described. Warning lights, signs, and warning flags are connected and secured to the tops of standard traffic cones either with or without the use of cone adapters. One end of a stainless steel aircraft cable connects directly to the traffic control accessories, while the other end of the cable is secured by a removable security disc and padlock within the traffic cone. Interconnecting the accessory and traffic cone together prevents injury to vehicles or individuals nearby if a traffic cone is accidentally struck by a vehicle, or encounters violent weather, causing the accessory to fly loose as a projectile. In addition a chain can now interconnect traffic cones in the system together, preventing theft of the traffic cones and/or accessories. Set up and knock down of the system is consistent with customary traffic safety control procedures.

Abstract: Two synchronous hydraulic polyphase motor-generators with axial cylinders are connected by rigid or flexible pipes. One functions as a generator, the other as a motor to transmit torque and power. Sinusoidal piston motion is developed without the use of cams. The pistons cause columns of fluid to alternate between motor and generator, producing synchronous rotation. Apparatus for synchronizing, coupling and decoupling the motive force are disclosed.

Abstract: A woman's sports hat is disclosed. A pin configured to represent the sport the woman intends to play while wearing the hat is inserted through two openings at the front of the hat so as to secure the hat to the woman's head. The hat will then resist being blown off in the wind, or falling off during physical, sports related activity. To further relate the hat and sport together a logo representing the same sport as the sports pin is imprinted or otherwise affixed to one or both sides of the hat. Reversible hats and caps can have different logos on the inside and outside of the hat so that the hat can simply be turned inside out, and the appropriate sports pin inserted in order to make the hat suitable for different sports, as, for example, golf and tennis.

Abstract: There is disclosed a methodology for measuring the magnetic field strengths of fundamental and harmonic frequencies associated with a.c. electrical current flows over a protracted period of time; and, particularly, in hostile environments. A preferable application calls for the determination of the field strengths associated with electrical currents flowing in a.c. power, distribution lines of utilities. The monitoring instrument is positioned in relation to the power lines to be monitored, typically at the base of a pole immediately adjacent the pole of the power line or on a power line supporting pole itself. In order to provide for long term, powering of the monitoring device, d.c. power is developed utilizing the a.c. power that is present. The conversion from a.c. to d.c. is effected at a distance sufficiently far from the monitoring instrument so as not to have any consequence on the readings that are being taken.

Abstract: A multiple print head, automated screen printing machine is described with improvements for inspecting and cleaning a print screen. The print screen and its frame are locked securely in position within a print screen holder, which in turn is locked into a precise spacial relationship beneath a permanently installed print head frame. The rear edge of the print screen holder is hinged so that an operator can hand lift the holder upwards, or activate an air cylinder which causes the holder to pivot upwards at its front edge. Provisions are also made for moving the print carriage with associated squeegee(s) and flood bar(s) entirely away from the area occupied by the print screen holder. Print screen inspection and cleaning is accomplished without moving the print head frame, providing additional safety for operators during these maintenance procedures.

Abstract: A multi-purpose carpentry measuring device is described. The tool combines the functions of a framing square, level and plum bob in one function and with just one measurement. Further, the tool can also be used as a bevel gauge and a level bench marker. A foot and leg member, joined by a pivot, contain bubble tubes for all necessary horizontal and vertical level measurements. Extendible rules on both members further increase the usefulness of the device. The tool has a built-in magnetic disc and bar code reader for continuously displaying angular read out on an integral calculator. Laser pin lights at either end of the tool allow for laser precision in all level bench marker observations as may be facilitated by a positioning pin disposed in said device.
