The thread guide flyer arrangement (5) provided for the lower yarn bobbin (3) is mounted between the two yarn bobbins. The second thread g...

Condensed steam containing oil emulsified therein and/or salts dispersed or dissolved therein is purified by supplying the condensed steam to an arrangement of two concentric anodes 6 and 8 with a cathode 7 therebetween, the electrodes being formed of porous corrosion resistant material and subjected to an impulse direct current. Electrolysis of water present causes gas bubble formation and format...

A roller construction for use on the lever arms of a front jaw of a ski binding. The rollers have a central opening therethrough which has a radially enlarging characteristic from the midlength portion thereof toward the axial end thereof. That is, the diameter of the opening adjacent the axial ends is greater than the diameter of the opening at the midlength portion thereof. The interior surface ...

Herbicidal compositions containing as active ingredients quaternary bipyridylium herbicides and additionally containing as a safety factor, an odorant alkyl carboxylic acid such as valeric acid and butyric acid.

PURPOSE:To measure the interference and thickness of a half-divided plain bearing simultaneously by forming a bearing supporting part having a bearing supporting block and a detector, a pressing mechanism and a thickness measuring element. CONSTITUTION:A half-divided plain bearing B to be measured is inserted into a half cylindrical recess 3. The recess 3 of the block 2 is formed on the inner diam...

The timepiece of this invention comprises at least one hand making a revolution in twelve hours and a disc making a revolution in twenty-four hours. A crown enables simultaneous setting of the hand and disc display when pulled out to the second position. When rotated in one sense while in the first pulled-out position the crown sets the disc only. Between the disc and the hand there is interposed ...

A display apparatus and method for displaying the value of the release threshold to which a ski binding is adjusted. The display apparatus is an electronic display means for electronically displaying the release threshold of the binding.

Provided between a spring and a member for setting the binding strength is a disc which has at least two units of stages of different strengths on its side engaged with the setting member. On its inside directed towards the spring, the setting member has support surfaces which are arranged in the same transverse plane, are arranged spaced apart in the circumferential direction, and on which are su...

The process for manufacturing pneumatic tires comprises as essential step the manufacture of a tire body by winding cords or cables (3, 23, 35). The cord or cable is withdrawn from a supply reel (7) under constant tension and laid around and anchored to the bead cores (2; 22; 36; 39) arranged at both sides of the tire. In addition a peripherally extending belt is applied which again can be formed ...

A rubber composition, expansible under vulcanization conditions consisting of at least one vulcanizable synthetic rubber, vulcanizing agents and a propellant gas donor under vulcanizing conditions consisting of (a) from 100 to 900 parts by weight, based on 100 parts by weight of said synthetic rubber, of natural, non-pretreated chalk, and (b) from 5 to 120 parts by weight, based on 100 parts by we...

Films which are clear, transparent, non-tacky, easily handleable, mechanically strong and stable at both low and high humidity conditions, and are rapidly soluble in cold and warm water are formed from blends of water soluble polyvinyl alcohol (partially hydrolyzed polyvinyl acetate) and polyacrylic acid, optionally with a plasticizer. The films are also heat sealable and biodegradable.

The invention relates to a method of producing coolant channels in a metallic object such as a cutting tool whereby a blank is formed by at least one working step such as compaction etc and the channels are formed by cores whereby the working takes place as a compaction at a temperature of at least 950 DEG C and that the core thereafter is removed in a separate step.

PURPOSE:To prevent flaws of forgings by working a heated rod material with the enclosed preform die and the preform extruding punch to form lobes and shaft, and then forging and finishing the material to provide a projection which serves as a dead metal on the connecting part between the lobes and the shaft. CONSTITUTION:Heated and descaled rod material is extruded by a full enclosed preform dies ...

PURPOSE:To make the stability of feeding to wire and the stability of arc better by constituting to push the wire inside through hole to the wall face of through hole by pusher. CONSTITUTION:A pusher 16 is pushed upward against the spring action of a spring 17 and passes through the tip of wire W since the pusher 16 is pushed by the tip of the wire W when it is inserted into a through hole 13. Aft...
