An apparatus for transporting a sheet of a flexible material between a first and a second position. The apparatus includes an elongated frame and an air-pervious endless belt movably mounted on first and second pulleys positioned at each end of the frame. The belt has its upper rung travelling from the first pulley, adjacent the first position, to the second pulley, adjacent the second position, a...

A method for preventing the irregular untwisting of yarn ends in pneumatic yarn splicing apparatus. The respective free yarn ends to be spliced are untwisted and loosened in the control nozzles and each untwisted yarn ends is cut at a predetermined position thereof. The cut yarn ends are overlapped in a splicing hole and spliced by the jetted fluid stream.

A continuous, completely jacketed countercurrent centrifugal extractor of the type utilized to mix and separate two liquids that have different specific gravities and enter through separate inlets. The extractor has at least one overflow weir in a mixing zone between the inlet for the specifically lighter and the inlet for the specifically heavier liquid phase and a division of the mixing zone int...

A one-piece blank (11) forms a liquid-tight carton having rectangular side walls (13, 15, 17 and 19) sealed or integral with one another at adjoining side edges (21) and flat end panels (25, 27) of polygonal shape, the end panels being sealed ultrasonically to the side walls through sealing tabs (29, 39). Ultrasonic heating and sealing of the upper end panel (27) is effected after the carton is fi...

The plate stacks are positioned for further processing in a clamping arrangement with clamping elements between stacks. Each element is displaceable by an amount of play X with respect to its neighboring element.

The mould cavity includes ventilation holes (11) leading therefrom, each covered by a perforated metal plate (7) flush with the interior mould surface (9); the plate is thin (e.g. 1mm) and has small holes (10) or passageways extending therethrough (e.g. 0.1 mm diameter). The plate may be supported as a result of being a press-fit in one end of the ventilation hole or as a result of being supported...

The invention relates to a method and circuit arrangement for magnetic recording of a digital data signal composed of a set of transitions. A recording signal is formed by superposition on the data signal of a high frequency, constant amplitude, magnetic biasing signal Sp. The biasing signal is phase-modulated relative to the data signal transitions. The invention remedies "peak shift" and can be ...

Polycrystalline alumina tubing is scribed by means of laser pulses which are reiteratively focused on the same spots at spaced time intervals. By drilling small holes, the laser need be on for a very short period of time only, and only the surface layers are vaporized, thereby minimizing heat shock. The holes are deepened by repeating the series of pulses and directing them sequentially into the s...

A centrifuge assembly incorporates a centrifuge bowl 1 having a filler piece 3 in which is formed an elongate channel 5. Removably disposed in the channel is a polyvinyl chloride tubular container 13 which conforms to the channel 5 and receives whole blood to be centrifuged so as to collect red cells, platelets and plasma. The channel 5 has two portions of which the first is wider than the second ...

A cop supplying apparatus in an automatic winder includes a full cop delivery conveyor belt and an empty cop delivery conveyor belt arranged along each of a plurality of winding units of the winder. A cop fitted on an individual cop deliverying carrier is travelled on the conveyor belt and a passage for receiving the carrier from the conveyor belt is formed in each winding unit. The cops are locat...

Dual-circuit electrical accumulator, i.e. an accumulator with two circuits, which contains various elements connected together in series and in which each individual element has positive plates connected in parallel with one another and negative plates connected in parallel with one another, which are arranged inside the element in a common acid enclosure and are separated from one another by mean...

In a high density solenoid operated multiple punch apparatus, having a punch head provided with the plurality of closely-spaced large bores arranged in column and rows that extend partially through the punch head from the top side, solenoid elements mounted in the large bores, a plurality of holes with a diameter smaller than the large bores aligned with the large bores and extending the remaining...
