Method of joining textile threads, respectively, formed of a plurality of twisted-together filaments by splicing the threads with the aid of compressed air, the threads being inserted into a splicing chamber having a compressed-air channel communicating therewith, the threads being fed from two sides of the splicing chamber and being held by respective thread holding members, which includes, prior...

Controlled compressed-air splicing device for textile threads with a controlled compressed-air metering valve supplied from a compressed-air supply device, including an automatic quality control device for ensuring the quality of spliced joints formed by the splicing device.

The thread splicing device in which the two overlapping and in line ends and combined pneumatically, holds the tips of the thread ends freely and uses two air jets to interweave them. Before splicing, the ends of both threads are reverse twisted, being clamped at positions spaced away for the thread tips, the two jets being spaced apart to produce the rotation. The thread splicing member (101) has...

The invention provides a method of moulding a plastics material comprising the steps of placing the material with a quantity of an appropriate catalyst in granular (including powdered) form into a hollow mould shell (1); suspending the mould in a mounting system enabling rotation in a plurality of directions whereby the powdered material, together with the catalyst, is able to flow over all the in...

A wound dressing comprises an absorbent material (1) and a surface layer of a non-absorbent apertured fabric (2). The non-absorbent apertured fabric preferably serves to present a smooth surface to the wound, minimising any possibility of adherence of the dressing to the latter. Absorption of exudate from the wound by the absorbent material takes place through the apertures in the fabric. The fabr...

A crushing apparatus is fitted with hammers which preserve the hammer spindle. The bores of these hammers have a wall which is made curved away from the hammer spindle towards the two edges, leaving a shorter, straight middle piece. Thus the individual hammer can execute a limited rolling movement on the hammer spindle, without unfavourably influencing the hammer spindle in doing so. Likewise the ...

The invention relates to a lead accumulator with a thixotropic gel consisting primarily of sulphuric acid and a gel former as an electrolyte, whereby the electrolyte consists of two different phases, a liquid, gel former-free phase, by which essentially the pores of the active materials are filled in, a solid phase, as a thioxotropic gel, by which the electrolyte space especially between the elect...

PURPOSE:To detect even such a fault that an operation end signal is held sent back by adding an AND circuit and a storage element to a fault detecting circuit and monitoring the state of the operation end signal. CONSTITUTION:Even when an electronic computer 1 outputs a start signal 6a while the operation end signal is held sent back from an input and output device, an AND circuit 12 ANDs it with ...

PURPOSE:To substitute any one faulty processor with a reserved processor by rewriting the address allocated to the reserved processor of correspondent table in the address allocated to an individual bootstrap loader corresponding to the processor in normal use. CONSTITUTION:The bootstrap loader for loading system programs SP1-SPN is divided into a common bootstrap loader CB that is common for all ...

Process for solid refuse disposal in which a vertical shaft furnace is maintained at 30-250 psia, part of the recycle-condensate is filtered to form liquid waste a portion of which is incinerated with a minor part of the product gas to form hot exhaust gas used to heat feed water in steam boiler zone, and energy from the resulting steam is recovered as part of the process energy requirement.

An arithmetic device having successive arithmetic registers connected in cascade, with buffer registers at each end of the cascade. An information exchange circuit bidirectionally connected to all the arithmetic registers for controlling information transfer therebetween such that the first register is connected to all of the other registers and every other register is also connected to a precedin...

A capacitor (12) which, by its charge or discharge, times the interval between successive signals at a computer output point which is being monitored so as to provide a reset signal to the computer when the interval exceeds a predetermined normal value, is held in a charge condition which produces a reset signal to the computer component, for a predetermined time after power is turned on. In one e...

Calculi, stones, calcified tissue and other material are broken down for removal from within a body using laser pulses that are delivered via an optical fiber and have a wavelength, intensity, energy per pulse and pulse duration selected to break down the object into smaller particles without delivering energy sufficient to cause damage to other tissue.

A speed sensing differential axle mechanism provides a plurality of teeth formed in a small diameter end portion of a differential case. In a preferred form, the teeth are integral to the case, spaced uniformly about the small diameter end portion thereof, and are disposed for relative rotation with respect to a stationary electronic pickup element secured rigidly in an associated external carrier...
