Method of and apparatus for splicing fibrous formations, particularly yarns. Mutually closely arranged parallel and overlapping ends of the fibrous formations to be spliced are disposed inside the pressure channel of a splicing chamber. The thus disposed fibrous formations are subjected to the whirling action of pressure air and at least at one of the mouth of said pressure channel they are subjec...

Method of and apparatus for preparing and splicing the ends of fibrous formations, particularly in the pressure channel of a pneumatic splicing chamber provided with a displaceable lid. Excess lengths of ends of fibrous formations to be spliced are placed within the pressure channel in overlapping substantially parallel relationship and are then cut to a desired length by cutting means such as sci...

A machine for slicing slabs of cheese, sausage or the like comprises a feeding mechanism which supports the slab, feeds it intermittently at an inclination to the horizontal and includes a slab-supporting conveyor belt and gripping claws for holding the back of the slab. The conveyor belt runs over freely rotatable direction-changing rollers and on both sides of the conveyor belt parallel to the u...

A process is described for the transfer of metal ions from an aqueous liquid into a non-aqueous liquid and from there into a further aqueous liquid. The non-aqueous liquid contains one or more complexing agents and is kept separate from the aqueous liquid releasing the metal ions by one or more microporous hydrophobic membrane(s). The non-aqueous liquid is circulated through two or more transfer z...

An X-ray unit for producing X-ray pictures is described wich operates on the bases of scattered rays. According to the invention, a diaphragm system is provided by means of which in each case one section of the area under examination is in each case allocated to one detector. This improves the contrast/noise ratio.

A combination apparatus for splicing and entwining fiber slivers. A nozzle support arrangement for the nozzles of a splicing mechanism is provided and comprises essentially round rods that are adapted to be disposed horizontally one above another, with the nozzles of the splicing mechanism opening on the surfaces of the rods via nozzle outlets that are surrounded by respective raised portions of t...

In processes for the working of fibre slivers 3, broken fibre slivers, the ends of which can be connected again by splicing, occur. It has been known hitherto, for this purpose, to load the fibre-sliver ends with compressed air by means of pairs of nozzles 7, 9; 8, 10 directed in opposition, the splicing of the fibre-sliver ends taking place by aerodynamic swirling. So that the spliced connection ...

To treat waste water (effluent) streams, which are polluted in different ways, from small dirty water settling tanks, and for manual or automatically adapted intake flowrate of dirty water, flotate outflow and return of purified water to the water consumer by only one pump, the connection sequence, intake of already purified water from a collection tank, division of the pressurised stream into two...

A system for controlling line pressure has a line pressure calculator for producing a line pressure signal in response to load on an engine and vehicle speed, a control signal generator responsive to the line pressure signal for producing a control signal, and an electromagnetic valve operated by the control signal, for controlling pressure of control oil in a hydraulic circuit of an automatic tra...

In an automatic winder, the tension device provided on each winding unit has a tenser in contact with a yarn to apply a resistance thereto, and a driving actuator of said tenser member, and each of the actuators provided on each winding unit is associated with a control device positioned separately from each winding unit, and adjustment of the tenser member is remote-controlled. The control device...

A pneumatic yarn splicing apparatus including a yarn splicing member having a cylindrical yarn splicing hole, air nozzles opened in the splicing hole, and a yarn inserting slit wherein the air nozzles are opened non-tangentially on the inner periphery of the yarn splicing hole to spurt compressed air toward yarn ends and have a shape of an elongated slot extending in the axial direction of the yar...

An automatic guided vehicle travels for a predetermined distance by detecting the distance covered, and thereafter stops when the mark located at the desired stopping point is detected by at least one sensor. Obstacles on the route, and cumulative error therefore have very little influence on the vehicle's travel, so that accurate travel control is obtained.

Apparatus comprises a rotatable member 2 situated in a pressurized or evacuated chamber, means for generating an electric field at the edge of the member e.g. ring electrode 5 having sufficient strength to overcome the surface tension of the metal, and liquid metal delivery means 14 directing liquid metal onto a surface 3 of the member over which the metal flows toward the edge as the member is sp...

In a method for the detection of blemishes on the surface of an object, e.g. for the detection of blemishes in the paintwork on the surface of a motor vehicle body, a strip of light is produced on the surface by means of a lighting system, and this strip of light is moved over the surface by relative movement between the lighting system and the surface; strip-like sections of the surface of the ob...

A method of testing security papers with respect to the positions of a safety thread and water marks to detect errors in the paper is performed by a linewise scanning of a finished paper web. The web has at least two point like measuring marks inserted into it in addition to the water marks, whereby impulses which are originated from these measuring marks are evaluated and the sheet width and the ...

An installation for vehicles moving automatically, without human intervention, between starting and arrival points along a predetermined path consisting of stops, junctions, crossings, inlets, outlets of elevators, etc. An installation in which each self-propelling vehicle is adapted to carry a load and has steering-wheels and a central driving-wheel as well as optical detectors designed to read a...

A method of detecting defects present at the surface and/or internally in transparent materials, particularly of detecting included foreign bodies or bubbles in glass, is disclosed. The test material is scanned with an electromagnetic radiation of a single wavelength which is set to the penetration depth in the test material. The intensity reflected by the defects is picked up and analyzed. By thi...

Hydrophilic thermoplastic polymers such as polyurethanes are stretched at a temperature above their glass transition point and then cooled to control axial swelling characteristics of the polymer in aqueous media; such polymers are especially useful for intravenous catheters.
