Apparatus and method for starting respective leading ends on web running continuously and would into successive rolls, such as paper. As each roll reaches a final diameter, a fresh leading end is provided on the web by slitting in a generally cross-machine direction from a leading starter tongue projection extending downstream. The starter tongue projection with the fresh leading end of the web is...

A continuous, completely jacketed countercurrent centrifugal extractor of the type utilized to mix and separate two liquids that have different specific gravities and enter through separate inlets. The extractor has at least one overflow weir in a mixing zone between the inlet for the specifically lighter and the inlet for the specifically heavier liquid phase and a division of the mixing zone int...

A carboxylic acid or carboxylate is reacted with an isocyanate to produce gas which is used to give a blowing action in the manufacture of a foam plastics material, especially foam polyurethane. Preferably formic acid or a formate is used.

An antimicrobial composition is prepared containing an aryl compound carrying an oleophilic substituent and a hydrophilic substituent, and an antimicrobial agent coordinated to the hydrophilic substituent. The oleophilic substituent is a straight alkyl radical from 6 to 24 carbon atoms and the hydrophilic substituent is a sulpho or hydroxyl group. The antimicrobial agent is an imidazole, a benzimi...

PURPOSE:To find easily a fault of a switch, by providing the switch between a gate which operates on time-division basis and the input port of a signal processing part, and checking a switch for input between the gate and a diode for display. CONSTITUTION:A microcomputer 1 outputs signals 100 and 200 as digit outputs D1 and D2 and also outputs an L-level signal 300 from segment outputs (a), (b)- (...

PURPOSE:To detect a runaway of a microprogram by the addition of less hardware, by setting an FF when dissidence is detected by the comparison of a comparator during microinstruction execution, or when a counters reaches a specific value. CONSTITUTION:A counter 25 is initialized by some microinstruction and increases by one synchronously every time a microinstruction is read out. The output of the...

PURPOSE:To prevent a runaway of a microprogram, by comparing the attribute of a microprogram set, block by block, in a control memory with the attribute of a microinstruction read out of the control memory and evaluating the microinstruction. CONSTITUTION:When an address where a runaway to another microprogram occurs is set in a control memory address register 1, the contents of an address corresp...

PURPOSE:To detect abnormality speedily and to minimize a down time, by outputting an AC route check signal every time a route check counter goes to 0 in the end of processing, and detecting the output externally. CONSTITUTION:The route check counter 9 is provided in the software processing routine of a microcomputer MPu8. The route check counter 9 is reset to 0 in the ending of processing when a n...

Mechanically alloyed powder is produced in a gravity dependant ball mill by processing to a level at which the powder has a laminate type structure at 100X magnification. Consolidated products produced from the powder exhibit substantially the same desirable characteristics as are obtained form the consolidation of attrited powders having a featureless microstructure and/or saturation hardness.

A hydraulic wheel cylinder assembly is particularly for use in a drum brake of the kind in which the wheel cylinder assembly is interposed between one pair or adjacent ends of a pair of brake shoes and a mechanical expander and fixed abutment is interposed between the other pair of adjacent ends of the shoes. The wheel cylinder assembly incorporates a pair of piston assemblies each including an ad...

Apparatus is disclosed for producing high purity metal powders of precisely controlled particle size. The apparatus employs a system for atomizing a stream of molten metal by a swirling fluid. After initial system set up, different particle sizes may be produced merely by interchanging atomization fluid inserts. Each replaceable atomization fluid insert includes an inlet for receiving a single gas...

A honeycomb filter having improved particulate capacity is provided by forming the filter from a matrix of thin interconnected porous walls defining a plurality of cells extending between opposing inlet and outlet end faces and closed near the outlet end face and, preferably, a porous outer skin surrounding the matrix of thin walls and extending between the inlet and outlet end faces of the filter...

A solution containing cellulose dissolved in a tertiary amine N-oxide solvent containing a nonsolvent for cellulose such as water is shaped by extrusion or other shaping process to form a shaped cellulose fiber, rod, plate, tubing or film. The extruded shaped article is stretched in air while still a solution to impart improved physical properties thereto and the cellulose is precipitated from the...

A surface treatment for ethylene/vinyl acetate copolymer film resulting in an elastomeric, heat sealable film which retains its transparency after release from 200 percent elongation. The treatment comprises irradiation and controlled surface hydrolysis and, optionally, subsequent attachment of mineral particulates to the surface of the film with or without the use of coupling agents.

A packaging film comprises a base film of at least partially water-soluble plastics film, for example, polyvinyl alcohol, carrying on one side a protective layer of particulate inert plastics material, for example, polytetrafluoroethylene powder, having a high water repellency. The film is thus vulnerable to attack by aqueous media on one side and protected against such attack on the other. It may...
