Title: Improvements relating to the back feeding of yarn to spinning machines
IPC: D01H4/48
Filed: 1967-08-23
Abstract: In Fig. 1 the driving drum 7 engaging a yarn package 8 is connected to a drive-motor 10 through a clutch 14 when this is engaged bevels 12, 15 are also engaged to drive rollers 4 in the take-off direction. When a feeler 3 detects a fall in tension in the yarn, a solenoid 20 is energized to separate the clutch and engage bevels 13, 17 so that the direction of rollers 4 is reversed. In Fig. 2 (not shown), a drum (22) is continuously driven. Rollers (24, 28) are geared to it so that they rotate in opposite directions. During normal working, a roller (23) mounted on a pivoted arm nips roller (24) to withdraw the yarn. When the tension falls, solenoids (30, 31) are energized solenoid (30) transfers roller (23) to roller (28) so that the yarn is fed back, and solenoid (31) causes a brake to engage and lift the package off the drum. In Fig. 4 a roller 36 on a pivoted arm and coupled to one of a pair of yarn withdrawing rollers, engages a continuously-driven roller 34. When, the roller 36 is transferred from roller 34 to the inner surface of a segment connected to roller 34, the withdrawing rollers are driven in reverse and at a faster speed. In Fig. 5 (not shown), nip-rollers (45, 46) are driven in yarn withdrawing-direction from a continuously-driven shaft (51), roller (46) being coupled with a larger roller (49) spring-urged into contact with the shaft, and roller (45) being spring-urged away from the shaft. When roller (45) is moved on to shaft (51), thereby forcing roller (49) away from the shaft, is Lriven faster and in the reverse direction. Reference has been directed by the Comptroller to Specification 1,074,788.

Title: Improvements to Apparatus for Measuring Thermal Conductivity.
IPC: F15B7/00
Filed: 1967-10-27
Abstract: Apparatus for measuring the thermal conductivity of a material comprises an envelope for containing a heating plate 1 sandwiched between two panel shaped samples 2, 3 of the material, the outer surfaces of the samples contacting walls 8, 9 of the envelope these walls being maintained at a constant temperature during a test, which temperature is in the region of but slightly below the temperature of the plate 1, the envelope being completed by a ring 10 inside which the plates 8, 9 can shift, the ring 10 also being maintained at a constant temperature, and a clearance being provided between the ring 10 and the lateral walls of the samples 2, 3. The temperature of the walls 8, 9 may be controlled by thermocouples connected to electric heaters in the walls, and the ring 10 may be such as to have a temperature gradient therealong ranging from the greatest value adjacent the plate 1 to the least value adjacent the walls 8, 9. In this way lateral heat losses from the samples 2, 3 are eliminated. The envelope is mounted inside a pressure tight container 13 and is embedded in granular material 16 in the form of spherical particles of alumina, zirconia quartz and a pressure may be applied to the material 16 and thus to the envelope to keep the components thereof in heat conducting relation by pressurizing bladders 17 inside the container 13. The gaseous atmosphere inside the container 13 may be monitored as to pressure, humidity, and composition, and the atmosphere in the container 13 may be circulated if desired. Measurements on the samples 2, 3 may be made at different attitudes by rotating the container 13 in bearings 21. Thermal insulation 14 is provided on the outside of the container 13 and the container is maintained at a constant temperature by a water heated tubular coil 15. By means of the above apparatus it is possible to measure the thermal conductivity of samples at different temperatures up to say 500 C., and to study the effects of changes in pressure and/or humidity on the samples.

Title: Method of producing non-sticky filamentary material consisting of copolyamide and polyolefin
IPC: D01F8/12
Filed: 1968-02-08
Abstract: Non-sticky copolyamide fibres are obtained by melt extruding a copolyamide containing an olefin polymer said copolyamide having been obtained by a melt copolymerization process including the steps of (a) dissolving the olefin polymer in a solvent inert to the melt polymerization system and having a boiling point below the polymerization temperature, (b) adding the solution to the comonomer reaction system before, or at least prior to completion of the copolymerization which is carried out or at least completed in the presence of the olefin polymer and (c) removing the solvent from the reaction system after the polymer has been uniformly dispersed therein. The copolyamide may be melt spun through a spinneret orifice concurrently with a melted homopolyamide. Extensive lists of copolyamides and olefine polymers are given. Pigments, dyes, delustrants, heat and light stabilizers, antistatic agents and plasticizers may be incorporated in the polymers. In examples polyethylene or an ethylene-vinyl acetate copolymer is incorporated in copolyamides of caprolactam with hexamethylene diammonium adipate or isophthalate by the method of the invention. The product of Example 3 is extruded side-by-side with nylon 6 in a conjugation ratio of 1: 1 and taken up on a bobbin as an undrawn yarn of 360 denier/ 28 filaments.

Patent ES-350795-A1 (ES)
Title: Textile winding machines
IPC: D02H3/00
Filed: 1968-02-22
Abstract: An empty beam placed on rollers 16 is lifted by a hydraulic ram 24 acting through levers 18, and engaged by a head stock 6 and a tail stock 8 moved along rails by rams 106, 108. During winding, the rollers 16 serve as presser rollers. The beam is driven by a hydraulic motor 28 supplied by a variabledisplacement pump whose output is controlled to keep the yarn speed constant. The speed is sensed by a tachometer driven by nip rollers 48 through which the warp is fed to the beam. When the yarn speed changes, a disc 56 is turned by the tachometer 52 to bring one or other of two slots 58, 60 opposite an outlet port 78 or 80 corresponding inlet ports on the opposite side of the disc receive low pressure compressed air from an inlet 68. Each outlet 78, 80 leads to a pneumatically-operated valve feeding high pressure air to a pneumatic motor, which rotates one way or the other depending on which valve is opened the motor adjusts the delivery of the pump supplying the beam driving motor 28. Restrictors in the valves limit the air flow and hence the acceleration of the beam motor, especially when standing from rest the pump is automatically adjusted to zero delivery whenever the beam drive is stopped. The desired yarn speed can be set by swinging the head 64 about the axis of the disc 56.

Title: Means and method for transmitting a high count rate pulse signal over a common well logging cable
IPC: E21B47/12
Filed: 1975-08-26
Abstract: A conventional type radiation detector in cooperation with a photomultiplier tube provides data pulses of one polarity, corresponding in peak amplitude and number to detected radiation in a borehole traversing an earth formation. Each data pulse is effectively converted to two pulses of different polarities, with one pulse starting when the other is completed and transmitted over a common well logging cable. The creation of a second pulse of an opposite polarity cancels out the low frequency component of the pulse so that they arrive at the surface as a pulse of a single polarity having a very short tail and a fast rise time. This permits more pulses to be transmitted within a given time period than heretofore existed. Surface electronics process the transmitted pulses to provide a record of the sensed condition in the borehole.
