One or several fabric loops are disposed along the running route of a web of paper. The loops are driven via reversing rollers normally belonging to the paper machine. Air blowers extending along the running route of the fabric loops are disposed so that air jets blown through them support the tail of the web of paper and press it toward the fabric that drives the tail forward in connection with d...

The major surfaces of a solid plate-like conductive core in an accumulator are adjacent to slabs of positive active material which are flanked by porous layers consisting of sintered synthetic plastic material or of compacted glass wool, synthetic plastic filaments or rock wool. A sheath consisting of polyvinyl chloride has a chamber which receives the core, the slabs and layers and is formed wit...

PURPOSE:To improve the battery life by initially charging an unformated plate fabricating lead-acid battery, when a current is flowed at low temperature initially and the temperature is increased gradually.

A tire building drum is described as having a unique mechanism for controlling the radial movement of the bead lock segments which are designed to hold the tire bead rings firmly, in position, during the tune-up operation. The mechanism includes an annular support member which is disposed concentrically around the longitudinal center axis of the drum adjacent opposing ends of the drum, and which h...

The present invention provides a mixing head for devices for joining textile threads with the aid of compressed air, for use indifferently for joining short-fibre threads and long-fibre threads, in both the cases perfect joints being obtained, both as regards their tensile strength, and as regards their aesthetical appearance, by being free from thickenings and undesired protrusions at the sides o...

The invention concerns the control of an infinitely variable transmission, provided with an endless transmission member running over a primary and a secondary V-shaped pulley, one conical disc of each pulley being affixed to a shaft, respectively the primary and the secondary shaft, and the other conical disc being controlled in axial direction by a hydraulic cylinder-piston unit, respectively the...

In order to mathematically detect the gear position of a vehicle transmission system, engine speed and vehicle speed are detected. A first reference level defined by a predetermined ratio of engine speed and vehicle speed is established for determining the gear position by a mathematical operation involving the sensed engine speed and the sensed vehicle speed and the reference level. The first ref...

The invention consists of a splicer device to disassemble and recompose yarn mechanically, whereby the splicer device comprises facing disks to untwist and retwist mechanically two yarns positioned between the two disks, a cutter to eliminate excessive tail ends of yarn protruding from the two disks, a crank to set the two disks in rotation, a cam to actuate the cutter that eliminates the excessiv...

This invention relates to a novel class of hydroxamic acid based collagenase inhibitor derivatives of the formula wherein R<1> is C1-C6 alkyl; R<2> is C1-C6 alkyl, benzyl, hydroxybenzyl, benzyloxybenzyl, (C1-C6 alkoxy)benzyl, or benzyloxy(C1-C6 alkyl); a is a chiral center with optional R or S stereochemistry; A is a -(@HR<3>-@HR<4>)- group or a -(CR<3> = CR<4>)- group wherein b and c ...

A navigation apparatus for vehicles, having an input unit (1) for entering input data, by means of which a specified destination can be entered with its destination coordinates relative to the starting point of the vehicle and can be evaluated to produce a destination vector. Furthermore, there is an output device which can indicate the instantaneous destination vector valid in each case in terms ...

Rotating cutting tool, in particular a drilling, milling and/or reaming tool, with a tool body having a pronounced longitudinal extension in the direction of the rotational or main axis and made of carbide or mechanically resistant material, which tool body has on its outside at least one groove running preferably at an angle to the axis differing from 0 DEG , in particular roughly helically, and ...

A spring-activated parking brake for a rail vehicle includes a pressure spring (4) working in a break-activating direction on a piston (2) which is connected to a spindle (7) with a nut (13) in non-self limiting engagement with this. This nut can be coupled to a regulator sleeve (16), which is rotational with a worm gear (18, 19). In order to allow not only manual return of the piston (2) by means...

A port assembly for delivering fluid through a shell of a rotary kiln is disclosed with structures for screening and excluding particulate matter from the port during operation of the kiln. The port assembly comprises a cylindrical nozzle defining a nozzle orifice to deliver fluid to the interior of a kiln. A base member secured to one side of the nozzle is provided with a platform extending partl...
