A continuous marine pipe laying system utilizes two rollers to overbend and straighten pipe as it is unwound from a reel. A support arm is pivotally connected to the axis of rotation of said reel and first and second roller arms are pivotally connected to the support arm at a point spaced from said axis of rotation. During use, the first roller is positioned at a point adjacent the pipe substantia...

In a radiological apparatus wherein radiation is passed through a body along a plurality of co-planar paths, attenuator means is utilized to tend to compensate for differences in the lengths of said paths within a body being examined. The attenuator means, however, introduces a variation into the radiation spectrum and the invention provides means for compensating for such variation. Such compensa...

A chuck or mandrel for a bobbin tube or sleeve serving as bobbin support embodying a thread catch ring and a thread severing ring defining therebetween a thread catching zone. The thread severing ring is provided at an end face with a substantially ring-shaped arrangement of spaced recesses and teeth formed between such recesses, these teeth each having an inner sharp cutting edge for engaging and...

An improved method and apparatus for a winder for anchoring an indefinite length of thread supplied from a supply source onto an anchoring disc in said winder. The method comprises the steps of offsetting the thread to a position facing the anchoring disc, spanning the thread vertically, arresting the spanned thread, protruding the thread outwardly from the disc, and displacing the thread slantly ...

A knotting arrangement, especially for spool frames for warping and other textile machines in which the orbital knotting head is connected to a suction tube and has a freely movable clamping body, e.g. a ball, therein which, when air pressure is supplied to the suction tube can press the ball against a seat to hold the yarn end. The clamping body is not connected to any elements within the head an...

An electromagnetically-operated adjusting means for the valves of displacement machines, comprises an oscillatory spring-mass system 12-20 which can be held by electromagnets (1,2) in each of two end positions of maximum oscillation deflection so that at least two discrete switching positions are achieved. The electromagnets and their armature(s) 17 are designed as part of a damping means and, at ...

The invention relates to a sheet feeder for the individual feeding of sheets to a sheet treating machine. A first sheet pile is carried by a main pile table, and sheets from this sheet pile can be fed by a sheet separating device, optionally via a first feed table, to the sheet treating machine. A further sheet pile is carried by an auxiliary pile table. Sheets can be fed by a second sheet separat...

In the comminution of material on a screw-shaped processing path by means of rotating hammers, a portion of the material already reaches its desired degree of fineness while still on the way to the outlet. It has to be entrained, with frictional losses, and undergoes an excessive comminution. This disadvantage is eliminated according to the invention, in that the cylindrical casing of the comminut...

In an apparatus for the comminution of garden waste, with a cutter disc (10) which can be driven by a motor, travels beneath a stationary counter-holder (22), and is arranged in a housing chamber (8) which is provided with an ejection channel (4) and into which there opens an input shaft (3), blocked at its lower end by the cutter disc (10), a trouble-free and reliable manner of operation is achie...

This invention relates to a power divider which distributes the motive power from a drive device to the front and rear wheels of a four-wheel drive vehicle etc, more specifically a subassembly for the power driver which makes the whole length of the power divider shorter with easy assembling.

Antistatic polyester films suitable for montage printing processes are made by coating the polyester film during or after orientation with an antistatic composition comprising lithium nitrate and polymeric binder, such as an acrylic copolymer.

There is provided a method of producing an open-cell polyurethane foam comprising heating a mixture of an aqueous emulsion of a polyurethane-forming composition and a fluorocarbon compound of 1 to 3 carbon atoms having a boiling point of 5 DEG to 100 DEG C. The above emulsion may further contain an ionic surfactant.

Polyurethane foams which may be rendered flame resistant by the addition of flame retardants are produced by reaction between a carbohydrate, a polyisocyanate and water in the presence of a suitable surfactant and polyurethane forming catalyst.

In detection of a defect in a part of an object having a surface which is substantially a surface of revolution, the surface of the inspected part is illuminated by light rays which are emitted through an annular portion coaxially disposed with the surface of the inspected part, and light rays reflected at the surface of the inspected part are received to form an image of the inspected part. The i...

In a data storage apparatus, memory chips are arranged in groups, each group having an address bus which is connected to the address inputs of all the chips in that group. Each address bus is terminated at both ends by circuits which perform the dual function of suppressing reflections and checking the addresses. Because reflections are suppressed, the time taken to address the store is reduced. O...

A method of making a printing plate from a negative microphotographic film by means of enlarged photographic projection which comprises the steps of impressing a code for detecting the respective frames of the negative microphotographic film on the blank space of said frames; automatically detecting any desired one of the frames by reference to the code; projecting the image of the detected frame ...

Moldings are described which are composed of a silicic acid with a layer structure, or salts thereof with the general formula (H,M)2SiyO2y+1, or the corresponding hydrates, M representing lithium, sodium, potassium or ammonium and y being 1.7 to 24. They can be prepared for example by extruding pulverulent layer silicic acids, or salts thereof with the general formula (H,M)2SiyO2y+1, or the corres...
