Abstract: Apparatus for riddling bottled wine having an elongated frame carried on resilient supports along the longitudinal sides of the frame and having a motor-driven eccentric weight carried on the frame for vibrating the frame and cases of bottles thereon in directions perpendicular to the longitudinal center line of the frame, together with rows of inflatable air bags along opposite sides of the frame for alternately lifting such sides and jostling bottles of wine within their compartments in cases supported on the frame. A clock system controls the power supply to the vibrator motor and the air supply to the inflatable air bags, the clock system being adjustable for supplying electrical current to the vibrator motor at pre-selected times and for periods of pre-determined duration, and for supplying air under pressure alternately to the air bags at one side or the other of the frame at selectively pre-determined intervals and for periods of pre-determined duration.

Abstract: A method and apparatus for reducing the rate of heat transfer between adjacent bodies, at least one of which is a body of fluid responsive to forces tending to move the fluid along the interface between the bodies, the fluid adjacent to the interface being more responsive to such forces by reason of heat transfer across the interface. The method collects fluid displaced along an expanse of the interface, transports the collected fluid to the other side of the expanse, and discharges it there for repeated displacement across the expanse to again be collected. The apparatus includes one or more distributor means and one or more collector means at opposite sides of the expanse, and one or more recirculating means for returning fluid from the collecting means to the distributor means. The recirculating means are power-operated fans or pumps, and may be individually servo-controlled.

Abstract: The method of riddling wine contained in bottles packed in shipping cases in which the cases are inverted to allow solids to settle into the necks of the bottles, tilting the cases from side to side to jostle the bottles, and vibrating the cases and bottles contained therein, the jostling and vibrating of the bottles serving to dislodge solids in the wine from adherence to the bottles so that the solids settle onto a temporary cap at the outlet of the bottle for disgorging when the cap is removed. The cases of bottles are tilted and vibrated for periods from about ten minutes to about thirty minutes to dislodge solid particles from adherence to the bottle, and the tilting and vibrating is halted for periods from about one hour to about six hours until tilting and vibrating is again effected.

Abstract: Constructing building walls from concrete blocks having flattened rectangular facing members held in parallel spaced relation by integral transverse webs spaced from the ends of the block by a distance equal to one-half the distance between the webs and providing a pair of V-shaped reinforcing of receiving notches having straight sides inclined at an angle of substantially 45.degree.. The blocks are stacked in equally staggered courses to define the wall panel and are held in position by a bonding agent securing the confronting surfaces of the blocks to each other with substantially no space therebetween. Vertical reinforcing rods are positioned in the vertically extending openings provided by the aligned webs of the blocks, and horizontal reinforcing rods are supported in the V-shaped notches, with the shape of the notches causing the rods to settle into desired positions on opposite sides of the vertical reinforcing rods.

Abstract: A trip-free vacuum circuit breaker is disclosed in which one or more vacuum switches are closed and opened by a second toggle mechanism which is controlled by a first toggle mechanism, and a solenoid operated linkage moves the fixed pivot points of the second toggle mechanism, thereby opening the vacuum switches independently of the first toggle mechanism.

Abstract: An attachment tool for a vacuum cleaner hose is disclosed taking the form of an elongated flattened tubular housing; one end being adapted to connect to a vacuum cleaner hose, and the other end terminating in a flattened air intake opening. One flat face of the housing has an elongated opening therein adjacent the other end of the housing; the elongated opening having a means for selectively covering it. A pair of elongated strip brushes extend along opposite sides of the elongated opening.

Abstract: A scrubber head has a handle with connections for parallel hoses to an adaptor which is interposed between a shower supply line and a shower head. A first valve in the scrubber head prevents water flow to the scrubber head or to the shower head. A second valve selectively flows water to a channel to turn a power disc. A parallel connected scrubber disc has a surface cover with microhook or loop-type fasteners to hold complementary fasteners on an annular scrubber pad. An annular sponge is mounted on a ring on the head outward of the scrubber pad for preventing splashes. The second valve may direct water through the channel and a spray head mounted centrally in the discs or back to the shower head.

Abstract: Apparatus for receiving video output from a patient scanning device and photographing a plurality of video displays sequentially in multiple images onto a sheet of x-ray film. A video monitor adapted for connection to a scanning device, such as a gamma ray or ultrasonic imaging system, and having a display tube mounted in a housing in spaced relation to a wide angle lens formed to project the image of the face of the display tube onto a sheet of film supported in a film holder mounted on the housing. The positioning of the image on the film is determined by the vertical and lateral positioning of the lens relative to perpendicular X and Y axes corresponding to the length and width of the film. The lens is provided with a shutter for controlling the passage of light therethrough, and a pair of reversing electric motors are provided for selectively positioning the lens along the X and Y axes.

Abstract: Apparatus for synthesizing motion pictures of a cyclically functioning internal body organ such as a human heart from the monitor control (X, Y, and Z) signals provided by a scintillation camera excited by radiation from a bolus of radiopharmaceutical material transiting or standing in the organ. The individual frames of the synthesized motion picture are recorded on a disc of photographic film which is rotated step-by-step by a digital rate-and-position servodrive. The picture quality of each frame is enhanced by repeatedly exposing it to the monitor screen image during substantially the same phase of successive functioning cycles of the organ. The organ cycle phase signals which serve as step commands for the servodrive are generated by a synchronizing circuit which is itself synchronized to the cyclic rate of the body organ being examined by means of bioelectrical signals derived from the patient being examined.

Abstract: A system for disposing of radioactive waste material from nuclear reactors by solidifying the liquid components to produce an encapsulated mass adapted for disposal by burial. The method contemplates mixing of radioactive waste materials, with or without contained solids, with a setting agent capable of solidifying the waste liquids into a free standing hardened mass, placing the resulting liquid mixture in a container with a proportionate amount of a curing agent to effect solidification under controlled conditions, and thereafter burying the container and contained solidified mixture. The setting agent is a water-extendable polymer consisting of a suspension of partially polymerized particles of urea formaldehyde in water, and the curing agent is sodium bisulfate.
