CONSTITUTION:A plate group 1 consisting of a positive plate 2, a negative plate 3, a separator 4 and so on is set to a fixed pressurizing state, while the periphery of these plates is molded wit...

In a device for splicing textile yarns by fibre-intermingling with the aid of compressed air, a pneumatic timing unit is provided for adjusting the duration of the compressed air jet. The unit essentially comprises a timing reservoir composed by a number of spaces interconnected with each other and communicating with the fibre-blending chamber, a cutoff valve controlling the flow of air from the a...

In a splice between ends of multi-ply yarn, each ply end (G1a, G1b) of an end of the multi-ply yarn (Z1) is disposed adjacent to an associated ply end (G2b, G2a) of the end of the other multi-ply yarn (Z2) so as to overlap it over a predetermined length (U1, U2), and each of these two ply ends (G1a, G2b, or G2a, G1b) has the respective other ply end (G1b or G2b) of the multi-ply yarn wrapped aroun...

In the carrier for beamed yarns, in particular for use on tufting machines, the beamed yarns run from one or more warping beams into the respective machine for processing. Each carrier (1) has only one warping beam (2) and can be brought into positive connection in the vertical direction with the feet (3, 3a) of other carriers. On its one bearing receiving side (8, 8a) it has an adjustable braking...

In a method for controlling a tire vulcanization of a vulcanizing apparatus, an initial green tire temperature is measured before vulcanization and a tire temperature during vulcanization is estimated on the basis of the thus measured initial tire temperature. In addition, a sum of products of vulcanizing rates derived from the thus estimated tire temperature is calculated so as to stop the tire v...

A holder for carrying personal items of value, i.e. wallet, passport, credit cards, jewellery, cash or any personal valuables, is in the form of flexible pouch and shoulder strap attachment. The shoulder strap attaches the said pouch to the wearer, leaving the hands free.

A device for positioning and firmly holding a test strip for optical-medical measurements, comprising a housing with a reception opening having a stop at the inner end for the test strip and a window which is positioned opposite the test zone of the test strip when it is inserted into the reception opening and it lies against the stop. The device also comprises a pressing mechanism acting substant...

PURPOSE:To conduct drives of each part with high accuracy as well as to meet a change of application very easily by driving engagement and disengagement of a feeding mechanism which reciprocates freely in a carrying direction and an in-and-out of a positioning pin with using an electromagnet. CONSTITUTION:A heater brock 145 goes up and down as an arrow 151, a snap-in lid 133 goes up an down as an ...

A device for determining the position of a moving part, particularly to a device containing a sensor carried by the moving part and designed to supply two out-of-phase signals, each assuming alternately the value 0 or 1 as the sensor is carried in one or the other direction. The device also has means of supplying pulses (ZD), each of which corresponds to one step forward on the part of the sensor,...

In a processing plant in which workpieces are conveyed to selected work stations according to a programme, the computer programme chosen for the plant operation and representing a simulated operating schedule is run through during the actual operation of the plant in synchrony with the latter. The plant comprises a number of sensors by means of which data on actual events taking place in the plant...

A device for transmitting signals from a transmitter at the bottom of a drill well to the earth's surface including a drill collar which extends in an axial direction, a transmitter disposed in the drill collar, a cylindrical metal sleeve from forming part of an antenna for electromagnetic wave transmission, the cylindrical metal sleeve being disposed around the drill collar and connected electric...

Very low molecular weight carboxymethylhydroxyethylcellulose polymers are used as additives for salt water cement slurries to lower the water loss therefrom when in contact with water permeable earth formations. The additives may also include hydroxycarboxy acids. The cellulose derivative has a DS of 0.1-0.7 (carboxymethyl), a molar ratio of ethylene oxide to anhydroglucose units of 0.6-2.8 and a ...

The wheel cylinder consists of a cylinder housing 1 which is supported against one brake shoe. Mounted for axial displacement in the cylinder housing is a piston 2 which can be acted upon by the pressure of a liquid. Further mounted for axial displacement in the cylinder housing is a thrust bolt 3, one end of which is supported against the piston 2 and the other end of which is supported against t...
