PURPOSE:To judge the operation quality of an ending machine using simple apparatus and procedure, by applying a tension higher than the tension of normal operation to a yarn immediately after ending and judging the ending machine to be abnormal when a prescribed frequency of yarn breakages take place by the repetition of the application of the tension. CONSTITUTION:A tension higher than the tensio...

PURPOSE:To reduce the initial investment with less processing step, simple work and no use of a heater or solvent by a method wherein flat items to be packed are placed between lengthy packing films coated with cold sealant, and the films are simply pressed and sealed around the items to be packed. CONSTITUTION:Polypropylene films 1a1 and 1b1 coated with cold sealant are wound around supporting ro...

PURPOSE:To reduce the packing losses due to phase shift by a method wherein before start of a packing apparatus, a differential driving motor for differential gears is brought in operation by a controller so that rotating bodies are brought back into a phase relation which has been stored in a memory circuit during the preceding operation. CONSTITUTION:A phase relation between rotating bodies Aa, ...

Highly abrasion-resistant transfer coatings are provided on a wide variety of substrates, thermoplastic or thermosetting, by transfer coating from a mold surface or a flexible web, such as by use of a heat transfer tape, an ultra-thin coating consisting essentially of a non-resinous binder material such as microcrystalline cellulose together with mineral abrasive particles, preferably alumina or a...

A method for transferring a continuously arriving web, specifically a paper or cardboard web, from a finished product roll to a new core rotating at the speed of web travel. The new core bears in the direction of web travel and before the finished product roll on a drum around which loops the web. The web is cut longitudinally, prior to running on the drum, for forming a transfer strip. Before rea...

A mould M particularly as used in the manufacture of a product from elastomeric material which is required to be heated. Preferably the heating is carried out by means of an electric current which may be induced electro-magnetically. The product may be a tyre (4).

A bobbin magazine for mounting on an end plate of a traveling service tender comprises a band movable on an endless path, compartments on the band to receive sticks of telescoped bobbins and a transfer device to transfer sticks from the magazine to the tender. The magazine can be hinged to the tender so that the magazine can be swung out to expose the end plate.

A cylindrical tire building former (11) has two sets of radially expandable segments (37) or (38) located one set at each axial end of the former. The sets of segments (37) or (38) are expanded by engagement of each segment with an axially moveable wedge member (36). The wedge member (36) may comprise an annular body, or an annular array of individual wedges. The wedge member (36) is moved by oper...

For the treatment of the surface of paraffin bodies (30) used for the paraffining of yarns, there is provided a device which holds the paraffin body (30) in a receptacle (10) and which is assigned means (20) for processing the surface of the paraffin body (30).

The chopper uses a rotary, slotted blade disc, which is powered by a motor within a housing and fitted with releasable blades, underside ejector vanes, and coacting counterblade (27). The latter bridges the blade disc (14) and is releasably fitted to the housing (11). A counter holder, pref. formed by a centrally projecting support surface of the counterblade, is arranged in the centre of the dis...

In a method for automatically controlling a vehicle transmission system having a gear-type transmission and a clutch, in the case where the system is controlled in a control mode wherein the clutch is disengaged so as to prevent idle running of the vehicle when the amount of operation of the acceleration pedal becomes less than a prescribed level, when the clutch is engaged in response to an incre...

Supercharge pressure is vented from the induction manifold in response to a shift command for a shift which requires engine torque reduction for shift shock attenuation. The ignition is subsequently retarded during the inertia phase of the shift. The supercharge pressure reduces the amount of torque being produced by the engine prior a further reduction by ignition retardation. At the end of the i...

In a center mechanism of a tire vulcanizing machine equipped with four kinds of hydraulic cylinders, lower end portions of a plurality of rods are made insertable into holes provided in a beam to transmit a pressing force generated by a pressurized hot medium to stoppers through the respective rods upon vulcanization of a tire. Upon completion of vulcanization of the tire, the stoppers are made to...

According to an engine torque control for a drive system including an engine followed by a continuously variable transmission, the engine torque drops quickly when the engine braking forward drive position (L range position) is set after a power demand on the engine has decreased to zero, while it drops less quickly after the power demand has decreased to zero when the normal forward drive positio...

Preparation of free-flowing pellets of ethylene terephthalate oligomer by water quenching droplets of molten oligomer.
