PURPOSE:To aim at making a V-belt type transmission miniaturized and lightweight without its transmission power being lower, by steppedly or continuously incleasing the inclined angle of a drive movable face outwardly in the radial direction. CONSTITUTION:A drive movable face 12a has an inclined surface with different angle alpha1, alpha2 on the center and outer peripheral sides, respectively, and...

PURPOSE:To facilitate centering at case assembling by respectively providing projection parts having approximately the same diameter on the outer pripheral part of a drive shaft and on th inner peripheral part of a counter shaft, allowing said projection parts to make contact with each other just before transmission case joining, and separating said projection parts from each other after the compl...

A ribbon drive and motor control system in which the instantaneous speed and torque output of a pair of motors are controlled interdependently to bidirectionally transfer ribbon or other web material between a pair of storage reels mechanically coupled to the motors at a uniform ribbon velocity and tension. The motors are electrically excited in series to rotate in the same direction with the back...

A tension-proof thread joint, includes two endless threads pointing in different directions, the threads having ends lying adjacent each other in lengthwise direction thereof forming a common thread end with an end section, the common thread end being twisted through one and one-half turns forming a loop with a thread eye formed therein, and the end section of the common thread end being extended ...

A machine for coating (closing, sealing) metal/plastic composite electrodes pasted with active mass and comprising fibrous-felt nonwovens or woven fabrics. The working temperature is between 150 DEG C and 250 DEG C. The closure pressure used is 1 to 50 newtons/cm<2>. The electrodes to be processed are introduced into the machine horizontally and held between continuously circulating platens protec...

The invention concerns apparatus for splicing spun yarns, comprising a pneumatic yarn-splicing element and yarn-end-holding nozzles which are arranged at each end of the yarn-splicing element and within which one of the yarn ends to be spliced is aspirated and held and subjected to a compressed fluid for backtwisting the yarn ends prior to splicing from an inclined injection nozzle provided in the...

Diurethanes of the general formula I wherein R1 is allyl or a C1 to C4 alkyl radical possibly substituted by halogen; R2 is a C1 to C4 alkyl radical possibly substituted by halogen, a C3 to C4 alkenyl or alkinyl radical, cyclohexyl, phenyl, C1 to C3 alkylphenyl, C1 to C3 alkoxyphenyl, halogen phenyl, benzyl or phenylethyl; R3 is a C3 or C4 hydrocarbon radical possibly substituted by h...

Apparatus for melting and dispensing heat softenable thermoplastic materials such as adhesives including a main body having therein a melt chamber, an inlet passageway leading into one end of said chamber, a discharge passageway in communication with the other end of said chamber, the melt chamber having an initial melting section with a generally round or circular cross section and a melt acceler...

An industrial truck is described in which an additional third sensor remote from the usual two tracking sensors is provided. This is said to improve cornering and reduce swerving during straight line travel. Four modes of travel may be provided i) straight passage between racks ii) straight passage away from racks iii) straight paths where the vehicle is not centred on the track iv) cornering, the...

Vanadium-treated aluminum particles are provided, and in particular vanadium-treated pigment pastes, pigments, paints, and aluminum flakes, such aluminum being thereby transformed to a form capable of resisting attack from an aqueous medium. The vanadium-treated aluminum flakes may be obtained by posttreatment or by milling aluminum with a compound capable of providing vanadium, such as ammonium v...

A magnetic field is induced in a well casing. The location of this field may then be sensed while drilling another well and the direction of drilling modified in response to the sensed location of the first well. This allows one to either avoid or intersect the first well with the second well.

A low density foam product is formed from a chlorinated polyvinyl chloride polymer (CPVC) composition containing a primary blowing agent and a nucleating system comprised of an alkali metal borohydride and a proton donor activator.

PURPOSE:To perform the setting of a boot in an automated manner, by feeding air from the caliper side in making a piston contact with the boot attached to a caliper at its one end by way of causing the piston to be slightly eccentric, while fitting the boot in the piston's peripheral surface. CONSTITUTION:A caliper 1 attaching one end of a boot to the cylinder opening side is supported by a holdin...
