Abstract: DOT MATRIX CHARACTER PRINTING USING         CONSTRAINED MEMORY                  Abstract In a wire matrix printer control system,  some characters from a finite alphabet are locally stored as compressed dot matrix objects reflectively symmetric about at least one axis. Upon being referenced and ascertained as a compressed object, the bits are applied to the printhead in column major order up to the axis of symmetry and then applied in reverse column major order. For uncompressed objects, the bits are applied only in column major order.

Abstract: ABSTRACT In a method for sterilizing packaging material, more particularly packaging containers, by means of a liquid sterilizing agent containing hydrogen peroxide, the sterilizing agent is atomized and mixed with compressed air, the resulting mixture is vapourized, the mixture of vapour and air is blown onto the surface of the packaging material to be sterilized, and the vapour is caused to condense thereon.  The sterilizing agent is atomized by means of compressed air over a heated surface and is thus vapourized, and immediately thereafter, the mixture of vapour and air is blown onto the surface to be sterilized.  The condensate occurring upon the surface to be sterilized is again vapourized, after a predetermined exposure time, by blowing hot gas onto it.

Title: Serial dot printer for office machines
Inventor: BOVIO MICHELE
IPC: B41J2/01
Filed: 1983-01-28
Granted: 1984-06-19
Abstract: ABSTRACT            The printer comprises a solid or liquid ink jet head arranged to print one dot at a time on paper running over a platen.  The head is carried by a carriage movable transversely with simple harmonic reciprocating motion. In order to reduce the effect of inertial forces when the carriage reverses its movement, the drive is effected by an eccentric peg on a disc, the peg engaging in a guide slot of the carriage perpendicular to the direction of reciprocation.  An eccentric cam track in the disc engages a peg on a counterweight for counterbalancing the inertial forces of the carriage.  In order to synchronize the print-ing operation with the carriage movement, an optical strobe disc is rigid with the disc and has slots disposed at a pitch varying according to the harmonic motion.  The platen is rotated intermittently by a helical cam carried by the disc and a peg wheel.  In order to compensate for discharge of a smoothing or reservoir circuit feeding the printing head, the duration of the pulses applied thereto can be increased in accordance with the rate at which dots are being printed.  In a modification the  strobe disc is re-placed by a linear transducer of capacitive type, with one part carried by the carriage.

Abstract: Ag/Pd ELECTRODING POWDER AND METHOD FOR MAKING                Abstract of the Disclosure Pure silver and palladium powders were thorough-ly mixed and dispersed by ball milling in a solution of a surfactant in a liquid vehicle.  After drying and granulat-ing, the resulting powder was heated to 500°C, thereby first forming an Ag/Pd alloy powder and then causing palla-dium to precipitate from the interior of the alloy parti-cles, so as to form a protective barrier of PdO on the alloy particle surfaces and to alter the alloy to 90Ag/l0Pd. This powder, when used to make a buried electrode in a ceramic capacitor, changes dimensions very little during the early stage of sintering of the ceramic up to 500°C, below which temperature the ceramic is weakest and most subject to cleaving.

Abstract: ABSTRACT OF THE DISCLOSURE The froth flotation device includes a flotation column partially filled with a packing which defines a large number of small flow passages extending in a circuitous pattern between the upper and lower portions of the column.  A conditioned aqueous pulp of a mineral ore, such as iron ore. is introduced into the midzone of the column.  A pressurized inert gas, such as air, is introduced into the bottom of the column and is forced upwardly through the flow passages in the packing.  As the air flows upwardly through these flow passages, it is broken into fine bubbles which intimately contact the floatable particles (e.g., iron oxide) in the aqueous pulp and forms a froth concentrate or float fraction which overflows from the top of the column.  Wash water is introduced into the top of the column and flows through the flow passages in the packing countercurrently to the float fraction to scrub entrained non-floatable particles (e.g., gangue) from the froth concentrate.  A tailing fraction containing the non-floatable particles is withdrawn from the bottom of the column.

Abstract: ABSTRACT   A method of manufacturing a low-pressure arc discharge lamp formed by interconnecting two or more parallel glass discharge tubes, each tube being sealed at one end.  A hermetically sealed arc-containing channel between the two adjacent tubes is formed by heating opposing sections of the two tubes to soften a first and second site on each of the respective tubes.  Then, one of the tubes is pressurized until a glass bubble forms from the softened site: the bubble is blown toward and onto the other tube about the softened site thereof.  The pressure in the first tube is then released, and pressure is applied in the second tube to form a second glass bubble which fuses with the first glass bubble and bursts into the first tube thereby forming the sealed arc-containing channel between the two tubes.  The technique may be applied to multiple tube assembled by alternating the end of the tube at which the joint is formed.  Once the tubes are joined, they may be processed by current manufacturing techniques to produce low-pressure arc discharge lamp.
