The automatic inspecting apparatus for a yarn joining device comprises devices for judging, when more than predetermined times of measured results within the doffing process are recognized to be abnormal, such, as a defective spindle, for generating an abnormal signal when judged to be abnormal, for setting a joining button of the winding unit to a joining stop position in response to the abnormal...

Porous electrodes for lead acid storage batteries without supporting plates or grids. The electrodes are porous, self-supporting, structurally integral and electrically continuous. Lead-acid batteries incorporating such electrodes exhibit improved performance characteristics as compared to conventional lead-acid batteries. The electrodes are made by forming a molten mixture of metal (e.g. lead) an...

A filter including a plurality of filter discs each formed with a central opening and disposed in a stack within a filter housing with the side faces of adjacent discs contacting each other for filtering the fluid flowing through the housing from its inlet to its outlet, the filter discs being maintained in a stack by a plurality of axially-extending rods arranged in a circular array around the ou...

The kitchen utensil for slicing vegetables is designed to be driven by a separate driving unit. The utensil consists of a housing (1) with a lid (2). The lid (2) has a tubular extension (13) with an opening to receive the vegetables. The vegetables are pressed downwards against the rotating blade (6) by an arm (4) which is guided by a linear roller bearing (5) on a vertical pillar (3). The rotat...

The invention is concerned with improvements in a web draw-in system for a web printing press comprising printing units with register rolls around which the web is trained, a draw-in bar to be attached to the leading end of the web and two tractive elements extending along the side frames of the press and guided by bend pulleys following the web path in the press. The tractive elements extend from...

To open out and untwist a twisted yarn, an air stream is used with at least two alternating and interrupted streams, directed towards the longitudinal axis of the air stream guide. The laternating frequency of the air streams is in the order of several hundred Mz.

Process for the preparation of alkanediols having at least two carbon atoms separating the alcohol groups, which comprises the reaction of a) an alkynediol and/or an alkenediol, of which the alcohol groups are separated by at least two carbon atoms linked by the alkynic or alkenic bond, respectively, and b) hydrogen, in the presence of a palladium compound and a base. r

A process for producing a titanium dioxide containing polyester resin composition from which a white film useful as a reflective photographic support can be prepared is disclosed. Said process is performed by first supplying a polyester resin and titanium dioxide into a continuous kneading extruder, kneading them in molten state, and supplying an additional charge of the polyester resin to give a ...

A gluconic acid syrup is introduced into a first crystallization zone 1a which it is brought to traverse under stirring and inside which it is maintained at a constant temperature, the mixture syrup and the gluconodeltalactone crystals emerging from this first zone being brought to traverse a second crystallization zone 1b within which it is subjected firstly to a temperature gradient decreasing g...

Biaxially oriented film of polyester derived from aromatic dicarboxylic acid and aliphatic glycol as main component has surface flatness (RCLA) defined by formula (I), where RCLAOis determined by the center line av. method, f(x) is the sum of vertical distance from a straight line of lengths L drawn across a surface roughness curve measured using a needle-contacting type surface roughness tester a...

PURPOSE: To make a cord holding means suitable for use for a cord which is subjected to a permanent deformation when it is bent around a small radius by making the cord holding means basically constitute a groove limited by two lip-like portions whose bottom portion describes a curve which is not closed. CONSTITUTION: A lever 2 is provided at its end with a cord holding means. Basically, the cord ...

A device for detecting any defects in single faced corrugated fiberboard while it is running. A light is irradiated to the corrugated surface of the fiberboard and the striped image is scanned by an image pick-up unit and the picture signal is converted to binary-coded signal to discriminate the number of stripes or corrugations. The number is counted by a counter and compared with a normal number...

This invention describes novel molded flexible polyurethane foam surfactants which can be used in foam having high concentrations of reinforcing graft copolymer solids. The invention also describes an improved process for making these foams using the novel surfactants.

In a heat exchange vessel which conducts a hot, pressurized synthetic gaseous stream carrying particulate matter through a central heat exchange chamber, a safety system for monitoring pressures within the vessel. Said heat exchange vessel includes a shell surrounding a water wall, defining an annulus therebetween. Pressure sensing means communicated with the respective heat exchange chamber and s...

An apparatus and method for stripping and depressurizing fine particulates mixed with gas discharged from a vessel operated at elevated temperature and pressure conditions to a low pressure vessel using a purge gas injected into a conduit designed for significant frictional pressure loss per unit length of conduit while maintaining a substantially constant velocity of the mixture conveyed.

Described are ways of improving the yields of specification grade polyimide foam on a consistent basis from one run to the next, by use of improved microwave-based foaming processes. In one such process, the microwave radiation is directed upon the top, sides and ends of the body of polyimide precursor and of the foam structure as it is developing, but the extent to which such radiation impinges u...
