Abstract: A forming roller for manufacturing moulded bodies with the rotary die method comprises a surface which is roughened at least in the region of the forming roller webs. By way of the roughening of the forming roller webs the adhesive friction for the material tapes from which the moulded bodies are manufactured is increased. The roughness of the surface parts of the forming roller is advantageously produced by the processing of the surface with a blast means.

Abstract: A bleeding or fugitive printing ink is disclosed and claimed which can be printed by the method of dry or wet offset or letterpress. This ink allows, when printed on security documents and dried, to prevent attempts of forgery or counterfeit in that the ink contains at least one dyestuff which is sensitive to organic solvents and other chemical reagents. The ink, when printed, forms a solid, polymerized or cross-linked binder matrix on the surface of the document when the printings are submitted to energy radiation, or by an oxypolymerization reaction. This matrix is formed near immediately, in the case of oxypolymerization within 24 hours, in contrast to conventional bleeding printing inks whose matrixes do not really dry and remain liquid in the interstices of the substrate.

Abstract: The present invention relates to inorganic particles comprising at least two chemical elements in a predefined and analytically identifiable ratio. These particles are used as a marking means incorporated into or applied onto any desired article. They provide a high security potential against counterfeiting since the analysis depend on a combination of spatial as well as of chemical information. In a first step the information containing particle has to be localized by scanning electron microscopy and in a second step the ratio of elements is analysed using energy—or wavelength—dispersive X-ray analysis (SEM/EDX).

Abstract: A food or drink container more particularly with an integrally formed handle or handles which can be assembled from a stacking position to a position of use is described. In one construction the container (1) comprises a cup-shaped part (2) which tapers from an upper rim (3) to a cone or round shaped base (4) terminating in a base rim (5) with a cutaway portion (6) forming an angled edge (7). Extending radially from the upper rim (3) is a winged projection (8) the center part (9) of which is horizontal to the upper rim. Two fold lines (10) are formed in the part (9) to facilitate the folding of two wings (12a, 12b) downwards as shown by arrows “A”. The edge walls (13) of the wings (12a, 12b) engage and abut each other in their fully folded down position to form a resilient handle.

Abstract: A footrest-table convertible article of furniture includes a pair of vertical supports, at least one brace rigidly interconnecting the vertical supports, a rotatable element disposed between the vertical supports, and a pivot connection supporting the rotatable element on the vertical supports for rotation about a horizontal axis. The rotatable element has two opposed major surfaces, one being a flat unupholstered table top, and another being a cushioned footrest. The rotatable element can be flipped 180.degree. between a position in which the table top is uppermost and horizontal, and a position in which the cushioned footrest is uppermost and horizontal. A locking mechanism secures the rotatable element in either of the positions, at a consistent height above the ground.

Abstract: An emulsion treater has an elongate vessel for receiving oil in which water is emulsified and gas is entrained, and for separating these impurities from the oil. The vessel is supported so that the axis is oblique through the horizontal, thus defining an upper and a lower end, each of which is closed by a head which may be hemispherical in shape. An elongate sleeve extends coaxially through the vessel and has an upper sleeve end projecting through the upper vessel head, and is itself closed by an upper sleeve head. At the lower end, the sleeve is open, with the open end being located at an intermediate position in the vessel. An elongate firetube extends coaxially through the vessel and the sleeve, and projects through the upper sleeve head and through the lower vessel head, thus defining a chamber with the sleeve which surrounds the firetube. A burner is provided for injecting hot combustion gases into the firetube at the upper end.

Abstract: A mixed oxide ceramic product is made directly from a metal alloy of titanium, zirconium and/or hafnium and niobium, tantalum or hafnium, where the normally combustible alloy of titanium and zirconium or hafnium is passivated by the addition of more than about 7 atomic percent of niobium and/or tantalum and or vanadium which alloy can then be heated in air at atmospheric pressure to a temperature of from about 800 degrees C. to about 1500 degrees C. to produce an adherent monolithic ceramic containing product.

Abstract: An oxygen analyzer is provided to detect the oxygen concentration of both a control gas and the output of an oxygen concentrator using ultrasound technology. The analyzer uses a calibration mode to alter the analyzer's output when calibrating it on the control gas. The analyzer is then switched back to its normal mode to permit a therapist to check the percentage of oxygen in the gas being supplied by an oxygen concentrator.

Abstract: A process of converting a feed of hydrocarbon-containing gases into liquid hydrocarbon products including a first reaction of converting the feed into one to 2.5 parts of hydrogen to one part carbon monoxide in the presence of carbon dioxide and then secondly reacting the hydrogen and carbon monoxide in a Fischer-Tropsch synthesis reactor using a promoted iron oxide catalyst slurry to form liquid hydrocarbon products, wherein the carbon dioxide from the first and second reactions is separated from the product streams and at least a portion of the separated carbon dioxide is recycled into the first reaction feed and the hydrocarbon products are separated by distillation and a normally gaseous portion of the separated products are further reacted in another Fischer-Tropsch synthesis reactor to produce additional liquid hydrocarbon product.

Abstract: A wastewater treatment installation includes at least two tank units having portions located in juxtaposed relation, the units being secured in such position. An inlet to the first tank unit communicates with a drop pipe connecting the inlet to a liquid delivery structure intermediate the top and bottom of the first tank unit, and located diametrically opposite the respective portion. The liquid delivery structure ejects liquid tangentially in opposite directions along the side wall of the first tank unit. An outlet from the second tank unit (or the last of a series of units) is located opposite the respective portion, and an outlet riser pipe connects the outlet to an intake opening, which is located intermediate the top and bottom of the second tank unit.

Abstract: Mechanical energy is supplied to an implement on a rotating spindle, and a generator on the implement converts the mechanical energy into electric power. Preferably the energy is supplied in the form of rotary motion via the work spindle. Alternatively, a fluent medium, for example, coolant or compressed air, can be supplied, in which case the medium is used to drive a turbine wheel coupled to the generator.

Abstract: A stable liquid suspension of an encapsulated flavor oil, oleoresin or spice in a gel matrix is prepared by forming a gel matrix with high shear mixing of a colloidal gelling agent at a temperature of about 15.degree. C., and dispersing the encapsulated flavor oil, oleoresin or spice in the gel matrix during the formation of the gel matrix.

Abstract: An accordion storm shutter assembly includes a frame for installation in an opening in a building wall and at least one folding shutter supported by the frame. The shutter is made up of plural blades articulated along their vertical edges so that the shutter can fold from a closed position in which the blades made a substantial angle--about 75.degree.--with one another so as to have a corrugated configuration blocking the opening, to an open position in which the blades are substantially parallel to one another. Neighboring blades are interconnected by continuous, extruded linear hinges, each having a socket which is substantially an arc of each cylindrical shell having a vertical axis. A knuckle formed along one edge of a neighboring blade pivots in the socket.

Abstract: An attache case has a partition whose upper surface supports a laptop or notebook computer. The computer is removably affixed to the partition by hook and loop fasteners or the like, and the fasteners may be easily repositioned or replaced when one upgrades or changes computers. Placement of the computer in the upper half of the case better conceals its existence, and when used, the computer is more accessible because of its elevation.

Abstract: Apparatus for moving workpieces from a relatively close spacing to a relatively distant spacing includes a block supporting a gear shaft for rotation, the gear shaft defining at least one pinion gear and at least two elongated rack elements which engage the pinion gear at diametrically opposed locations, so that rotation of the gear shaft causes the racks to slide in opposite directions. The racks are connected to gripping devices which can grip the workpieces for movement therewith.

Abstract: An anti-theft device is installed in a vehicle brake line which carries braking fluid. The device defines a valve seat and a valve body adapted to close against said valve seat, the valve body having a passageway therethrough and being rotatable against said seat about an axis substantially perpendicular to the passageway, between a first position in which it permits fluid flow in one direction and inhibits fluid flow in the opposite direction, and a second position in which it permits fluid flow in both directions. The valve can easily be switched between the first and second positions, and can be locked in the first position. By allowing braking fluid to flow only toward the wheels, it will be evident that the wheel brakes, once applied, cannot, be released.
