The invention relates to a device for the winding of yarn on a tube to a yarn package which device is equipped with a traverse unit. The device imparts to the yarn a traverse motion in axial direction with respect to the tube. The circumference of the yarn package is clear of any element. A pneumatic detector located near the circumference of the yarn package pneumatically detects the distance bet...

PURPOSE:To provide a differential gear of a car such as an automatic tricycle or the like which can be easily machined and simply assembled by forming a key way which is axially opened on the inner surface of a center spider, and retaining a key by a circlip. CONSTITUTION:A driven side bevel gear 26 is fixed to a center spider 30. The center spider 30 is ring-shaped and tooth-like projection group...

PURPOSE:To enlarge the size of a bearing, by embedding a bearing support sleeve at the time of casting, so as to secure the sleeve to a support member. CONSTITUTION:A ball bearing 101 is made of an iron having a lower coefficient of thermal expansion than a fixed member 157, and includes balls 101A and an outer race 101B. When the fixed member 157 is cast, an already molded sleeve 156A, which has ...

A safety binding for use with a ski including holding, support and intermediate members, and an elastic system. The holding member is adapted to hold one end of a ski boot onto the ski, and the support member is adapted to be attached to the ski. The elastic system acts on the holding member to press the intermediate member against the support member. In addition, the holding and intermediate memb...

A heat wave shielding lamination consisting of at least two In2O3 shield layers containing different amounts of Sn is provided on the surface of a glass substrate to provide shielding against heat waves without causing heat wave pollution in the surrounding environment. The amount of tin contained in the respective layers increases with increasing proximity to the substrate. The heat wave shieldin...

A tire building machine and method employing a tire building drum for receiving at least one ply of tire material having an edge overhanging an axial end of the drum, a bladder turn-up mechanism extending axially outwardly from the drum, an annular array of radially contractible ply-down fingers movable axially to and from a position encircling the overhanging ply edge, and an axially movable ring...

A memory data coincidence device includes a volatile read write memory connected to a main power source and auxiliary backup power source, and a keyboard for supplying data to the read write memory. The device further includes a read only memory for storing all data capable of being stored in the read write memory and a central processor unit (CPU) which compares the data of the read write memory ...

A method of communicating is disclosed in which the receiving device acknowledges the receipt of a valid transmission and awaits the receipt of an abort message from the transmitting device before accepting the transmitted data. The transmitting device awaits the receipt of a valid acknowledgement and, if it fails to receive such an acknowledgement within a predetermined time-period, transmits an ...

A quantity of tantalum powder is heated to a temperature greater than 400 DEG C in a non-oxidizing atmosphere to dissolve the tantalum oxide film existing on the surfaces of the tantalum particles. The treated powder without conventional organic binders is compressed to form a unitary pellet in a mold maintained in an inert atmosphere. The pellet is subsequently heated in a vacuum to sinter the p...

PURPOSE:To monitor and display discontinuation of data of more than a prescribed time, by providing a timer which measures the elapsed time after receiving data at every time when data of one character quantity are received to a receiving side system and discriminating whether or not the elapsed time exceeds a prescribed time before the next character is received after one character is received. C...

The present invention comprises a heat shield element (60) having a central opening (62) for receiving the reduced diameter portion (40) of a piston (16) of a disc brake (10). The heat shield element (60) is disposed between a metallic retainer ring/heat shield (50) and the convolutions of a flexible boot seal (30). The retainer ring/heat shield (50) maintains the axial position of the heat shield...

Acrylic films having superior properties are produced by casting a solution comprising an organic solvent and a polymer system of one or more completely polymerized acrylic polymers onto a carrier, removing the solvent thereby forming the film on the carrier, and stripping the film from the carrier. The polymer system comprises at least one polymer prepared by polymerizing monomers of the general ...

A composition useful in producing an open-cell, elastomeric silicone foam combines a silicone oil-in-water emulsion, which forms an elastomer upon removal of the water, with an aerosol propellant. When the composition is discharged to atmospheric pressure, a froth is formed. Removing water from the froth yields an open-cell foam. The froth is stabilized by surfactants, thickeners, or froth stabili...

A process is provided for making a liquid composition of a perfluorinated polymer having sulfonic acid or sulfonate groups in a liquid medium by contacting the polymer with a mixture of 25 to 100% by weight of water and 0 to 75% by weight of a second liquid component such as a lower alcohol, e.g., propanol or methanol, at a temperature of at least 180 DEG C. (at least 240 DEG C. when about 90% t...

TITLE PERFLUOROCARBON COPOLYMER FILMS A perfluorocarbon copolymer film which, upon heat shrinking, does not expand in the direction perpendicular to stretching. AD 5241A

This invention provides an understanding of the structure and porosity of soil and stony regions. The method is characterized by release of a measuring gas in the region being investigated and its penetration through the investigated region to several places where it is captured and measured. Thus, the measured data from the various measuring locations provides the structure and the porosity of th...
