Abstract: A diffraction camera type imaging device for x-rays/gamma rays/neutrons employs at least one single crystal bent to conform to the radius of a sphere of radius 2R and ground to fit snugly on a Rowland sphere of radius R will, when rotated about an axis normal to the axis of symmetry of the crystal or translated rectilinearly along said axis of symmetry, focus, by Bragg diffraction, a two-dimensional x-ray/gamma ray/neutron radiating object to a two dimensional image.

Abstract: The invention presented herein is a suction device for removing particles from the cutting area of a cutting tool via a duct arrangement including a large particle separator, a blower, a cyclone separator, a bypass means whereby a portion of the outlet air of the cyclone separator is used as a medium to transport particles separated by said cyclone separator and the remaining air outlet of said cyclone separator is recirculated to the cutting tool in the area of the vacuum pickup means.

Abstract: Aquatic sports zones are reclaimed or made by bounding non-shore areas of the zone with a plurality of end-to-end connected water impervious flotation boom sections, anchoring the formed boom in the bound zone, and attaching the ends of the boom to pier bulkheads, and providing the boom with a ballasted skirt having a length greater than the maximum normally anticipated water depth at the point of attachment of the skirt to the boom. Where desired, water purification means may be included in the bound zone.

Abstract: A system for cooling and freezing goods by cooled air is described, in which a series of large, rectangular plates carrying the goods pass over a first roller track into an ascending lift in a freezing room. The lift successively receives the plates and carries them stepwise to the top of the freezing room where the plates are carried over in a descending lift, which is operated in time with the ascending lift, and which successively deposits the plates on a second roller track for removal from the freezing room.

Abstract: A tumbler pin-type cylinder lock wherein the lock cylinder is mounted for controlled axial or axial and radial movement relative to the lock cylinder housing characterized in that the key and the cylinder have cooperating surfaces for axially shifting the cylinder toward the device actuating position. The cooperating surfaces comprise a conical depression on the lock cylinder and a cooperating pointed element at the inner end of the key. The conical depression is also characterized by having an opening in the center aligned with a counter bore extending axially through the cylinder.

Abstract: The cover consists of rods 10-12, arranged perpendicularly to each other, to retain shaped plates B1 showing, next to the longitudinal edges thereof, coupling members 30, 34, 35, as well as anchoring members 24, 25, 50.Plates B1 are designed to retain coating blocks for pavements made of wood or of other materials, which are retained to plates B1 by means of tongue-and groove connections.

Abstract: A durable crease is formed in a textile article by applying a flexible casting compound in a preformed crease using a non-rotary applicator in conjunction with a structure for guiding the applicator along the crease.

Abstract: A weighing machine wherein a mechanical change corresponding to weight of a body to be measured is taken out as an electric signal thereby to provide digital indication of the weight comprises a base body, a metering spring, a load supporting link associated with the metering spring and movable to displace the metering spring in response to the weight, a fixed electrode plate consisting of an electrically conductive flat plate secured to the base body, a movable electrode plate interlocked with the load supporting link and consisting of an electrically conductive flat plate intended to provide capacitance between the fixed and movable electrode plates and a digital indication and processing circuit for detecting change in the capacitance to provide digital indication of the weight.

Abstract: A wetted parallel plate collecting electrode arrangement which increases the maximum electric field intensity possible without having water draining off the lower edges of the collecting electrodes forming small droplets which are accelerated towards the opposite electrodes. An electrically conductive partition plate maintained at a voltage intermediate the voltages on the electrodes is disposed between the lower edges of oppositely charged electrodes and extends above and below the lower edges of the electrodes. Preferably, the partition plate is electrically "floating" and receives its voltage due to the effects of the electric field between the collecting electrodes.

Abstract: A durable crease is formed in a textile article by applying a flexible casting compound in a preformed crease using a non-rotary applicator in conjunction with a structure for guiding the applicator along the crease. A screw driven piston within the applicator dispenses the compound in response to applicator travel.

Abstract: Above and below water and land pile cutting machine is provided having a main frame which is quadrangular in transverse cross-section and is shaped to receive in the center thereof the pile to be cut. The upper portion of the main frame carries extensible pile gripping clamp means; the center portion carries four circular saws each mounted on a carriage mounted for transverse reciprocation and the lower portion of the frame carries further pile gripping extensible clamping means.

Abstract: The invention relates to floor polishing machines comprising a rotary brush drive means for the brush and means, such as a fan, for producing an updraught around the periphery of the brush to assist in removing particulate matter from a floor being polished.

Abstract: A chambered element for use in forming a roller screen has a pair of longitudinally extending chambers separated by a common wall and means are provided by the wall-forming elements of one of the chambers for coupling a co-extending finishing member.

Abstract: An absorptive and protective patient underpad is characterized by its ability to absorb substantial volumes of liquid, while maintaining a relatively dry top surface and the underpad is further characterized by a layer between a top cushioning layer and a lower absorbent layer which will permit liquid flow into the absorbent layer and reduce to a minimum the generation and release of offensive odors from the absorbent layer.

Abstract: The use of various polycyclic nitrogen-containing compounds, such as triphenylmethane dyes to potentiate the bioactivity of antibiotics of the phleomycin series.

Abstract: A process for reducing the pollutant concentration of effluent liquor from wool-scouring operations. The suint concentration of scouring liquor is allowed to build up to a point where suspended dirt and grease particles are destabilized and hence more efficiently removed by centrifugation. The centrifuged liquor is then recycled for further wool-scouring. Apparatus is also provided.

Abstract: An active gas plasma arc torch and a method of operating the same, said torch including a rod-shaped cathode, a first gas passage formed around said cathode to feed a protecting gas or shielding gas, a second gas passage formed around said first gas passage to feed a plasma gas and a constricted port for discharging the plasma gas, characterized in that at least a part of the shielding gas which flows out from the first gas passage is removed from the inside of the torch at the position short of said constricted port of the torch, whereby the working quality and the working speed are substantially improved while the rod-shaped cathode is satisfactorily protected by the shielding gas.

Abstract: A cleaning pad with an internal well for cleaning agent consists of at least one surface formed from a tufted textile fabric with the inner ends of the yarns forming the tufts in communication with the cleaning agent in the well, through yarn-containing openings in a plastic film separating the tufted fabric and the well.

Abstract: A Stirling cycle thermal engine or refrigerating device wherein there is no primary mechanical connection between the displacer pistons and their associated power pistons, including various mechanical and pressure fluid means for varying the power output from or the power input to the device.
