A method of detecting a significant difference of a to-be-checked sheet includes the step of scanning a traveling to-be-checked sheet (1) by a camera in the width-wise direction to obtain image data, extracting an outline of an image and an outline of a defect on the to-be-checked sheet from the image data, sequentially writing the outline data extracted in the outline extraction step in a memory ...

Method and apparatus for building annular tire components such as steel cord tread reinforcements, in which a measuring drum is employed to receive strip material and simultaneously to feed it to a component building former. The strip material laps a portion only of the measuring drum, and a measured length of the strip is severed on the measuring drum and the major portion of the length of strip ...

A method is provided for administerin...

The bond strength between a sulphur-vulcanizable rubber and a metal, especially brass, is increased by using as bonding promoter an organic substance containing one or more groups of the formula -S-SO2R where R represents (a) a radical -OM where M is a monovalent metal, the equivalent of a multivalent metal, a monovalent ion derived by the addition of a proton to a nitrogeneous base or the equival...

A process for the preparation of tack-free, free-flowing, filler-containing, rubber particles which comprises: a) the addition of a rubber latex and a solid filler to an agitated aqueous coagulating medium, having a pH in the range of from 0-4.5, and at such a rate as to provide an aqueous slurry of filler-containing, rubber particles, b) treating the rubber particles as prepared under a) with a...

A percussive-action mole 10 is energised by compressed air supplied through hollow rods 36 in a string 12 connected to the mole. A hydraulic motor 18 rotates the string and mole. The mole head 30 has a slant face 32 and a transverse permanent magnet 34. After each new rod is added to the string, the air is stopped to halt the mole which continues to be rotated. The field fluctuations from the magn...

The present invention is an improved process for separating alcohols from ethers and/or hydrocarbon raffinate in an etherification process. The excess alcohol reactant which forms azeotrope mixtures with the product ethers and C4-C7 raffinate, is removed by passing the liquid azeotrope mixture over a pervaporation membrane which effectively breaks the azeotrope and permeates the alcohol with high ...

In the initial operation phase of a data recording apparatus, a controller (9) detects the output signal of a position detector (8), thus determining whether or not the objective lens (62) of an optical head (6) is facing the non-recording region (B) of an optical disk (1). If the lens (62) faces the non-recording region (B), the controller (9) turns on a semiconductor laser (7), whereby the laser...

This invention provides an erasable optical disk, on which information is recorded and reproduced repeatedly through the irradiation of laser beams, and an optical information recording/reproduction apparatus which records and reproduces information on the erasable optical disk. In erasing and then recording information on the erasable optical disk by using an erasing laser beam and a recording/re...

Prepn. of water resistant, biologically degradable sheets with high mechanical strength formed from polypeptides (gelatine) derivatised with ethylenically unsatd. gps. is claimed. The peptide (gelatine) inccorporates known photoinitiators used in photopolymerisable paints and coatings. Derivatisation of the peptide with ethylenically unsatd. gps. produces carbon-carbon double bonds that are polyme...

The prodn. control system uses an automatic process for the execution of orders by a prodn. plant that can involve a wide range of different machines and work cells. The processing system is organised with a control unit (K) that identifies the instruction and activates a prodn. planning unit (P). The planning unit accesses the system data base, which contains tables of data indicating machine res...

The friction device operates with a gear wheel (150 fixed on a shaft (16),and has at least one friction body (10 - 13). At least one spring element operates with an opposing, synchronised body (17) against the friction action, rising via centrifugal force. The spring element comprises at least one ring element (1), with at least one plate spring tongue (2 - 5) which operates in an essentially radi...

In a process for the production of a shaped article involving the remelting of a polyamide which has been subjected to a drying stage, such as that which occurs during solid phase polymerisation, the stage of conditioning the polyamide prior to remelting can be reduced or even avoided by adding a controlled amount of water to the polymer when molten or immediately prior to its remelting.

A resiliently flexible strip device mounts the armature of an electrically released brake for movement toward and away from the pole faces of the field shell, the armature either moving with pivotal motion or with linear motion. The resiliently flexible strip device may take the form of one or more leaf springs or may be one or more tongues molded integrally with the flange of a bobbin which forms...

Fibre-reinforced rubbery polymers are prepared by mixing polymeric para-phenylene terephthalamide fibre with a solution of a rubbery polymer in a hydrocarbon solvent, and recovering the product by removing the solvent, in which either the fibre is subjected to fluffing prior to mixing, or the mixture is subjected to shearing agitation.
