PURPOSE:To remove slack of a yarn end to obtain a good seam by providing a nozzle pipe for untwining the yarn end and suction-retaining same, and reducing the open area to the diameter of the pipe to heighten the suction-retaining force so as to increase the speed of a running suction air current. CONSTITUTION:By ejection of compressed air from a jet orifice 32 mounted obliquely, a cut yarn end is...

A bobbin holder for receiving and securing a conical or cylindrical tube is provided with a support tube, a conical clamping ring axially movably mounted on the support tube, and a pair of spreading levers each having a free end and being pivoted for movement toward or away from each other in a plane which includes the axis of the support tube. The clamping ring and the spreading levers are spaced...

A power transmission device of a motorcycle comprising a main transmission case formed integrally with an engine crank case and accommodating a main transmission, and a subtransmission case provided at the rear side of the main transmission case. The sub-transmission case accommodates a subtransmission which is drivingly connected to the main transmission and also to a rear wheel of the motorcycle...

The essence of the method of extracting or recovering meat of small crustaceans, e.g. antarctic krill, resides in that crustaceans are introduced into an air flow relative to the surface of the crustaceans at a given velocity required for creating a pressure drop across the internal space or cavity of the crustaceans and the air flow. Consequently, the inter-cavity pressure breaks up the shell and...

A chemical analysis slide frame assembly including first and second slide frames each having an opening whose area is smaller than the area of a chemical analysis film inserted therein and a third slide frame disposed between the first and second slide frames. The third slide frame has an opening which is adapted to receive the chemical analysis film and is shaped so as to substantially prevent th...

A puncture sealant package for incorporation into a pneumatic tire is formed by coextruding a puncture sealant, and a skin forming material. The ribs are formed in an initially circular package profile as chords. After flow in a sheet die, the chords form divider ribs making small angles with the encapulating skin. The compartments formed by the ribs prevent flow of the sealant toward the center o...

An organic, high-molecular weight polyester containing substantially chain members of the formula -O-X-O-Y- wherein X is at least one member selected from the group consisting of and Y has the formula having an inherent viscosity of at least 1.0 dl/g, preferably at least 1.2 dl/g measured at 30 DEG C. in a solution of 0.5 g of the polyester in 100 ml of a mixture of 60% by ...

A tape coated with an adsorbent and impregnated with a processing solution which includes silver nitrate, an acid, an alcohol and a glycol is a sensitive detecting means for hydride gases and is stable upon exposure to light.

This invention relates to a pneumatic tire comprising a tread surface and two separate side parts of an elastomeric synthetic resin and optionally reinforcing elements, wherein the side part not only forms the side wall of the tire but extends from the rim wire to the mid-line of the tire and therefore also forms the foundation for the tread surface on one side, and to a process for the manufactur...

A pneumatic tire comprising an encircling tread and two side members, wherein each side member comprises a side wall having a bead ring and part of the tread backing, characterized in that said tread backing has the following features: (a) the tread backing is formed as a ring which extends to the center of the tire and is intimately joined to the side wall on the other side; (b) bands whose lengt...

An apparatus is described which is particularly suitable for applying insulation in the form of plastic foam or the like to a surface of a container to be insulated. The apparatus deposits a strip of foam in a generally helical manner while following the contour of the container or structure.

1464435 Dry distillation and thermal decomcomposition of solid waste HITACHI Ltd 7 May 1974 [9 May 1973] 20094/74 Heading C5E Hydrocarbons are produced by the dry-distillation and thermal decomposition of solid combustible waste containing plastics by using a fluidized bed, comprising the steps of: (a) separating and removing solid carbon and ashes from gases produced through thermal decomposition...

PURPOSE:To utilize car shredder dust as a fuel and to make a basic slag pollution- free, by charging a basic slag into a rotary kiln and then passing a combustion gas generated in the combustion of car shredder dust. CONSTITUTION:A basic slag contg. 3-15wt% water or a residue thereby from which a base metal has been recovered is charged in a rotary kiln. Then a combustion gas generated in the comb...

A circuit board socket is provided with a silicone rubber seal to prevent flux, solder, or other impurities from entering the interior contact areas. Viscous liquid silicone rubber is applied to an opening communicating with the interior of the socket and flows completely into the opening prior to curing to form an effective seal. After the silicone rubber sets, it may be easily pierced by a lead ...
