[Class 112] A card cylinder, the mechanism connecting the needle plates with the embroidery frame, and the needle plate clearance of a jacquard machine are actuated by linkages instead of cams. A coupling rod 9 connected to an eccentric 8 and an anchored link 13 forms the common basic linkage. The mechanism 31 connecting the needle plates and the frame is actuated by links 17, 29. The pivot 15 connecting 17 and 9 describes a curve c, the lower part e being a circle with a pivot 27 as centre. The link 29 remains stationary while the pivot 15 is describing the curve d and is raised to actuate the mechanism 31 while the pivot 15 is describing the upper curve d. The mechanism actuating the needle plate clearance 24 comprises an anchored linkage 20, 21, 23 which is connected to the pivot 15 of rod 9 by a further link 16. The curve d is a circle of radius equal to the length of the link 16 and while the pivot is tracing d the linkage 20, 21, 23 and mechanism 24 is stationary. During the tracing of the curve e the mechanism is actuated. The mechanism actuating the card cylinder is on anchored chains 85, 87, 115 which is connected to the pivot 82 of the rod 9 by a link 83. The pivot 82 describes a curve, part of which is a circle b with centre 84. While the circle b is traced the linkage 85, 87, 115 is stationary. Actuation of the card cylinder secured to the link 115 occurs during the tracing of the upper part of the curve a. The link 115 moves the card cylinder and its operating worm bodily to allow the cylinder to be rotated through a step by a cam actuated rack. The frame 102 is controlled from the carriage 53 described in Specification 421,700 by a rack 61 and locking pawl 69 which are actuated by a linkage 42, 71, 76, 78.

Title: Improvements in the treatment of regenerated cellulose fabrics to reduce their tendency to shrink
IPC: D06M11/40
Filed: 1946-05-31
Abstract: A fabric consiting at least in part of regenerated cellulose fibres is rendered resistant to shrinking on wetting and subsequent drying by treating it with a solution of a swelling agent, removing the swelling agent by washing, stretching the fabric in both directions to dimensions in excess of those ultimately required in the finished article, drying the fabric, p  and then heating it while still stretched so that on subsequent release of the tension and on wetting, the fabric will not shrink appreciably below the required final dimensions.  If desired, the fabric may be stretched before the removal of the swelling agent, in addition to stretching after removal of swelling agent.  A solution of caustic soda of 2-5 per cent strength if used alone or of higher strength if used with a moderating substance such as glycerine, may be used as swelling agent.  An aqueous solution of caustic potash of 10-40 per cent strength may be used.  The fabric which has been rendered plastic by the swelling agent may be dried before the swelling agent is washed out.  Removal of alkaline swelling agent may be assisted by treatment with acids. The heat treatment may be effected at 100-150 DEG  C. for a few minutes, but the temperature may be as high as 200 DEG  C.  In an example, a viscose rayon fabric is immersed in a solution containing 100 grams of caustic soda and 120 grams of sodium chloride per litre.  After squeezing, it is stretched in the warp direction, but allowed to shrink slightly in the weft and dried under tension at 70 DEG  C.  The tension is released and the fabric is soured in dilute acetic acid and washed.  It is stretched again in the wet state to 10 per cent beyond the loom state in the warp and 5 per cent below loom state in the weft.  It is dried at these dimensions and heated for 2 minutes at 150 DEG  C.  In another example, the swelling agent is a solution of caustic soda and potassium chloride.  Viscose rayon crepe fabric, slub spun viscose rayon fabric, and spun viscose poplinette may be treated.  Very dilute sulphuric or hydrochloric acid, or sodium bicarbonate may be used for assisting the removal of the swelling agent. Specification 462,899 is referred to.
Patent GB-587153-A (GB)
Title: Solubilized cellulosic material and solutions thereof
IPC: C08B1/00
Filed: 1943-10-12
Abstract: Solutions of cellulosic material are obtained by treating wood pulp, cotton linters or rayon in the form of powder, sheets or fibres, with an aqueous solution of sodium or potassium zincate of a concentration such that if established in a sodium zincate solution of the cellulose it would cause precipitation of the cellulose therefrom and diluting the mass of solubilized material by adding water, ice, dilute sodium hydroxide or dilute sodium zincate solution until the material dissolves.  The solution may be used as a coating, an adhesive, or a spinning solution for the manufacture of threads and sheets.  The cellulose used initially may be modified or degraded by heating the unmodified material to 50 DEG  C. with a strong solution of sodium zincate.  The zincate solution should contain an excess of alkali metal hydroxide and may be prepared by mixing zinc oxide, hydroxide, or a zinc salt with excess aqueous sodium hydroxide.  The temperature of treatment may be as high as 50 DEG  C. or as low as 5 DEG  C., and when the solution temperature after dilution is below 15 DEG  C., the solution is stabilized by warming promptly to 15 DEG  C. or higher. The solution may be ripened before use.  If desired, the concentrated zincate solution in the original treated mass may be pressed out and the treated cellulose stirred into a dilute solution of sodium zincate.  Numerous examples are given, in one of which rayon staple fibre is stirred with a solution of sodium zincate at 50 DEG  C. and the mass cooled to 25 DEG  C.  Ice is added gradually until the temperature falls to 3 DEG  C. and until the cellulose is completely dispersed.  The dispersion is then warmed promptly to 15 DEG  C., and ripened for 24 hours at room temperature. Specification 573,767 is referred to.

Abstract: 1,255,468. Digital data processing. BURROUGHS CORP. 9 April, 1970 [9 July, 1969], No. 16825/70. Heading G4A. An apparatus for connecting any unit of a first group of units to any unit of a second group of units comprises a switching means for effecting connection and a store by which requests for connection to a particular engaged unit are dealt with. The switching means is a matrix and requests are dealt with on a first come, first served basis (Fig. 1, not shown). When a request is received the apparatus checks whether the requested unit is free and, if not, the request is stored in a stack register with a priority depending on its time of arrival. When the requested unit becomes free the requesting unit with the highest priority is connected thereto. Circuitry (Fig. 2).-The requesting unit sends a signal to priority control 27, and information designating the requested unit to exchange control 26. A register 28 stores each request in synchronism with a clock pulse and signals exchange control 26, and a register 30 designates which of the requested units are available, register 30 being set by exchange control 26 each time a connection is made. A register 32 records which requesting unit has priority and a register 34 determines which units are connected and sets register 32. A scanner 36 (e.g. a ring counter) resolves simultaneous conflicting requests and allots priority, and a compare unit honours requests in the priority order from priority sections SR1, SR2, SR3 &c. of the stack register 44. When a communication is completed, stack register control 48 cancels the number of the requesting unit from the stack and shifts the remaining numbers up one in the stack. The detailed circuitry is shown in Figs. 3A, 3B (riot shown). If the requested unit is immediately available it is connected by way of the scanner which scans the requesting units in sequence.
