Title: Improvements relating to the saponification of cellulose ester materials
IPC: D06M11/38
Filed: 1944-07-14
Abstract: Filaments, ribbons, films and the like of a cellulose ester of a carboxylic acid are completely saponified by means of an alkaline aqueous medium in the presence of a lower aliphatic aldehyde, for example, formaldehyde, acetaldehyde, propionaldehyde or glycollic aldehyde, and a salt such as sodium sulphate or potassium sulphate which represses the swelling effect of the saponifying bath on the cellulose ester.  Examples of other suitable salts are given in Specification 453,302.  The process may be applied to the treatment of high tenacity yarns obtained by stretching yarns of a cellulose ester of a carboxylic acid, e.g. the yarns described in Specifications 438,655 and 438,656.  In an example, skeins of cellulose acetate yarn are saponified at 80 DEG  C. in a bath containing 0.6 per cent of sodium hydroxide, 3 per cent of formaldehyde and 25 per cent of sodium sulphate.  In a second example, the amount of formaldehyde in the bath is 1 per cent, and the yarns are treated on bobbins.  The Specification as open to inspection under Sect. 91 refers to the addition of an aliphatic aldehyde to a saponification bath for material comprising fibres, ribbons or films of a cellulose ester of a carboxylic acid and specifies also glucose as a suitable aldehyde.  This subject-matter does not appear in the Specification as accepted.

A method of bulking continuous multifilament thermoplastic yarns includes the step of correlatively controlling the speed of the yarns passing in contact with at least one heated surface, the tension on the yarns and the temperature of the heated surface to maintain the tension lower than the dynamic retractive force on the yarns so that shrinkage of some only of the filaments occurs with consequent convolutions of the others, the convoluted and shrunk yam being then merged and plied with another yarn. The yam may pass in contact with two heated surfaces prior to merging with the other yam, the first heated surface having a temperature in the range 150-400‹F. and the second a temperature in the range 300-600‹F. The yarn is caused to travel at 100-1500 feet per minute under a tension in the range 0.05 to 5 grams. The multifilament thermoplastic yarn is one selected from the group-polyamides, polyesters, acrylics, polyolefins and tri-acetates. The other yarn is selected from the groupcotton, flax, rayon, wool, texturised or untexturised thermoplastic yarns. Apparatus for carrying out the method comprises a yam feeding means 3, a heated surface 15, a yarn receiving means 5, a speed regulating means 33, 35 operatively connected to the yarn receiving means, temperature regulating means 19 operatively connected to the heated surface, tension regulating means 13 positioned upstream of the heated surface, merging means 23 located downstream of the heated surface for merging the multifilament yarn 1 with the other yarn 25, and plying means for twisting the merged yarn composite as it is received on the yarn receiving means.

Title: Improvements in devices for the automatic control of variables
IPC: G05B1/04
Filed: 1937-05-14
Abstract: 497,219. Automatic control systems. LAUCHLAN, A. D. E., and CAMBRIDGE INSTRUMENT CO., Ltd. May 14, 1937, No. 13725. [Class 38 (iv)] Temperature &c.-In systems for controlling a variable such as the temperature of a furnace wherein the deflection of a galvanometer, or the like, sensitive to the variable is associated with intermittent or continuous self-balancing of the galvanometer circuit, and in which corrective control of the variable is effected in recurring cycles, the magnitude of the corrective control applied in each cycle is determined by the duration of contact between a single pair of contacts. In apparatus according to Specification 366,290, [Group XXXVIII], a snail cam 2 causing a contact 14 to move to and fro over a fixed path is driven from the shaft 3 operating the means for periodically restoring the galvanometer index to zero. A cam 7 shaped according to any desired law is fixed on the spindle 1 which is displaced in each cycle according to the deflection of the galvanometer and this cam operates a contact 13 so as to interpose it in the path of the contact 14 so that a certain duration of mutual contact occurs when the variable is not at the controlled value and its rate of change is nil. When the cam 2 is adjusted so that the contact 14 is at its outermost position just as the self-balancing mechanism completes its cycle the contact 13 will travel towards the contact 14 when the rate of change of the variable is positive and in the opposite sense when negative so that the correction applied with depend upon the displacement of the variable from its correct condition and upon the sense of its rate of change. As shown the contacts are associated with a cam-actuated reversing switch 15 in the circuit of a reversible motor 6 controlling the correcting means which switch, together with the contacts 13, 14, is carried by a drum 8 whereby the desired value of the variable is determined.

Title: An arrangement for transforming rotary motion into a continuous progressing motion
IPC: F16H37/12
Filed: 1924-06-06
Abstract: 232,436. Mirkov, T. June 6, 1924. Turning. - Relates to means for converting rotary motion of a shaft into the continuously progressing rectilinear motion of a member, such as the slide-rest of a lathe. A cam 4 slidably secured to, a driving-shaft 1 is engaged by rollers 12, 13 on the arms 14, 15 of levers 16, 17 turning on pivots 18, 19 on brackets 20, 21 secured to a support 9 adjustable on the frame 10 under the control of a rod 51. The support 9 also has arms 7, 8 retaining the cam 4 in position on the shaft 1. Slotted faces on the levers 16, 17 engage rollers 22, 23 carried on slides 24, 24<1>, which move on a guide 25 at right angles to the shaft 1. Screwed rods 27, 28 slide through collars 26, 26<1> on the slides 24. 24', free motion in one direction being prevented by collars 49, 50 secured to the rods. The slide-rest 29 engaged by the rods 27, 28, which are formed with reduced ends sliding in the frame 10 and splined to engage spring-pressed friction cones 32 engaging the coned interiors of intermeshing wheels 35, 36 which gear with wheels 40, 41 loose un a shaft 39 driven from the shaft 1 by gearing 37, 38. A rocking clutch pawl 44 connects the wheels 40, 41 loose on a shaft 39 driven from the shaft 1 by gearing 37, 38. A rocking clutch pawl 44 connects the wheels 40, 41 alternatively to the shaft 39 under the control of rods 42, 43 pressed by a spring 47 against a control arm 48 secured to the support 9. Each roller 22 or 23 is in turn pressed to the left by its lever so that one rod 27, 28 pulls the member 29 to the left, in which process its rotation is stopped, the coupling 32 slipping while the wheels 35, 36 rotate. At the same time, the other rod is rotated by its coupling and screws to the right through the member 28, the parts being so formed that the second lever is moved by its roller 23 or 22 to keep the roller 13 or 12 in contact with the cam 4 in readiness to take up the drive when the cam has turned through 180‹. The member 29 is thus kept constantly in motion towards the left. The rate of feed can be varied by adjustment of the support 9; the position of the axis of the pivots 18, 19 in relation to that of the rollers 22, 23 is thus changed, and at the point of coincidence the feed is zero and the arm 48 is so placed that the rod 42 contacts with its end 53. With further movement of the support 9, the direction of feed of the member is reversed and the rods 42, 43 are released so that the clutch pawl 44 clutches the wheel 41 to the shaft 39 to reverse the direction of rotation of the rods 27, 28. Two such devices may be applied for longitudinal and transverse feed, respectively. By suitable variation of the rates of the two feeds, blanks of any desired form may be produced.

Abstract: 1299002 Drilling machines KERNFORSCHUNGSANLAGE JULICH GmbH 24 March 1970 14314/70 Heading B3C A drilling machine for drilling small holes in a number of drilling cycles operates as follows: a threaded spindle is operated by a hand wheel 10 until a nut 11 is positioned such that when drill spindle 1 is lowered so that a drill just touches a workpiece then nut 11 abuts surface 15. Thus when the machine is started an initial fast feed of the drill spindle is provided via a drive shaft 2 and a gear-wheel 8 until the nut 11 meets surface 15 when the forward movement of the spindle stops and a magnetic clutch (6), Fig. 1 (not shown), between drive shaft 2 and a driven shaft (7) is caused to slip. The nut 11 operates a switch contact 5 which starts a variable-speed motor 14 to drive shaft 9 and thus feed the spindle forward. A time relay is also activated which after a preset time stops motor 14. Also by a known circuit the magnetic clutch (6) is disengaged and a spring 16 returns the spindle to the starting position to enable swarf to be removed from the drill. This drilling cycle is repeated until the necessary depth of hole is achieved. Another time relay may be provided for the magnetic clutch which operates after the motor 14 has stopped for a time suitable for ligting the drill and removing the swarf. The spindle 9 may be changed to control the required spindle feed although motor 14 can give fine adjustment of the feed speed. Driven shaft 7 is driven through a worm gear 3 and the spindle is driven by a V-belt. To enable fine adjustment of nut 11 a ratchet 17 is provided on the driven shaft of the motor 14 or on the threaded spindle 9. The machine could be operated by hand via a hand lever (18) and hand wheel 10.
