Title: Method of automatic transportation of laps between lap-winding and combing machines and apparatus therefor
IPC: D01G21/00
Filed: 1964-10-06
Abstract: A lap-winding machine and sets of combing machines which it supplies by means of fully automatic lap-transfer apparatus are linked by an endless overhead rail on which spaced lap-carriers driven by a common endless chain continuously travel and each is operable by clasping and release mechanisms to collect a lap, which has been automatically doffed from the lap-machine and then lifted into the path of the oncoming carrier, and subsequently deposit it on the first available unloaded combing-machine feeder. When an unloaded carrier approaches the lap-machine (and assuming a wound lap has been doffed and awaits transportation from one cradle of a horizontally traversable receiving apparatus thereby) it operates a limit switch to actuate an electromagnetic-valve controlled hydraulic mechanism of lifting apparatus whereby the cradle with the lap thereon is positioned in the path of the carrier: a second limit switch at the clasping position is then engaged by the carrier body to cause two electromagnetic-valve controlled hydraulic pistons to force spring-loaded, normally open or spread, pivoted arms of the carrier into a closed position in which their hook ends engage in projecting open ends of the spool on which the lap is wound: the lap is removed from the winding station as the carrier continues its travel and, after an interval determined by a time-delay relay, the lifting and clasping mechanisms return to their former positions.  If, as a loaded or unloaded carrier approaches the lap machine, a lap has not been doffed, then an initiating relay for lap receiving, lifting and clasping controls is not energised and the carrier passes over the lap-machine &c. without incident.  If, when a doffed lap is awaiting transportation, a loaded carrier approaches, then the lifting and clasping apparatuses remain inactive as the carrier pases the station but the receiving apparatus is shifted (by limit-switch operated, electromagnetic-valve controlled, hydraulic piston) on trolley wheels so that an empty cradle thereof is positioned to receive the next doffed lap.  When a loaded carrier arrives at an empty feeder, it actuates another limit switch to energise solenoids the core extensions of which rotate locking levers whereby the arms of the carrier spring open to release the lap.

Abstract: 1413674 Extruding reinforced cable sheaths LYNENWERK KG 5 Sept 1972 41209/72 Heading B5A [Also in Divisions D1 and H1] A self-supporting aerially suspended cable for power or telecommunication transmission comprises an extruded polyolefin insulating sheath 14, e.g. of polyethylene, or of copolymers of ethylene or propylene, Fig. 5, in which has been incorporated during extrusion, glass fibre single or doubled yarns 24 which are not provided with a binding agent for the polyolefin and are arranged as a number of transversely compacted bundles 23, which are circumferentially spaced and are of radially undulating configuration in the axial direction of the cable. The radial undulation arises from cooling shrinkage of the polyolefin and the undulation amplitude is greater for larger bundle diameters. The bundles should be spaced circumferentially apart, and from the interior surface 25 of the polyolefin, by a distance of at least twice the diameter (d) of a yarn. The cable core 13 about which the insulating sheath is extruded, may comprise an assembly of a spiral quad of two twisted conductor pairs 19, Fig. 2, provided with insulation 17 and covered with plastics tape 22. The sheath may be extruded around a pair of such conductor quads, Fig. 3 (not shown), or five, (Fig. 4 (not shown), arranged around a strand (21) of plastics material. The singles or doubles nature of the yarn, the filament fineness, and the number of bundles for conductor pairs numbering 2, 4, 6 and 10., are stated. The tubular sheath is applied to the core 13 by an extrusion die 11, Fig. 1, into which each glass fibre bundle is delivered through passages 26 which are progressively constricted to compact each bundle to not more than 110% of the cross-section occupied in the cable, the final compaction being obtained by the extrusion pressure of the polyolefin, and its shrinkage when cooled downstream of the die. Occluded air is removed from the bundles by reduced pressure within the passages 26. The undulating configuration of the bundles arising from the shrinkage of the polyolefin is controlled by the magnitude of a braking force applied to the bundles.

In a magnetometer of the type using Hall effect in a semi-conductor, the voltage across the output electrodes of the semi-conductor crystal is compared with a voltage at the slider of a directly-calibrated potentiometer fed with a current proportional to that flowing through the feed electrodes of the crystal. In Fig. 3, the potentiometer, calibrated in Gauss and crystal 21 are fed in parallel from the source 27. Resistor R5 is first adjusted so that the galvanometer 40 reads zero when switch 37 is open. The switch is then closed and the potentiometer 34 adjusted for balance. Temperature errors in crystals having a negative temperature coefficient of resistance are minimized by using resistors R1, R2 having high values compared with the crystal 21. Temperature compensation may also be achieved by means of a resistor 39 having negative temperature coefficient and mounted in contact with the crystal. Hall effect crystals specified may be of germanium, silicon, indium antimonide or indium arsenide.

Abstract: 1,268,105. Fluidic device. PITNEYBOWES Inc. 22 Aug., 1969 [12 Sept., 1968], No. 42060/69. Heading G4P. A fluidic device has a membrane not greater than À001 inches thick in one line which blocks the flow of fluid therethrough while permitting the passage of sound. The device comprises two turbulence amplifiers 10, 12 fed with air from an outlet tube 20, 76, having interaction chambers 28, 36 and outlets 30, 38, 40 respectively. Amplifier 10 has a bell shaped control passage 52, 54 having a taut thin plastic membrane 60 (e.g. polyethylene terephthalate resin) secured therein by a collar 62. In the usual mode of operation, with no signal to the control passage 52, air enters chamber 28 frominlet 22 and flows laminarly to outlet 34 which acts as a control passage for amplifier 12. This causes turbulent flow in the latter and the air is vented down outlets 38, 40. If an acoustical signal reaches membrane 60 the latter vibrates, hence causing the fluid above it to vibrate and hence causing a control signal at port 54. This causes turbulent flow in chamber 28, hence ceasing the signal in outlet 34, causing laminar flow in chamber 36, and an output signal in line 40, 72. On removal of the acoustical signal the flow returns to normal. The passages are grooves in a board 16 covered by a bolted down plate 18 with a gasket therebetween.
