Title: Improvements in or relating to machines for buffing parts of boots or shoes or otherarticles
IPC: A43D95/08
Filed: 1924-08-22
Abstract: 243,074. British United Shoe Machinery Co., Ltd., and Gouldbourn, J. Aug. 22, 1924. Band apparatus; driving and feed devices; guides and rests; tables, slides, and carriages. - A machine for buffing boot and shoe parts &c. comprises an abrasive band 2 supported by a drum 3, the work being fed through the machine by feed rollers 52, and pressed against the band by presser members 1. The members 1 are slidably mounted in a carrier 8 and each is pressed by a spring 9. The carrier 8 is movable towards and from the work under the action of a spring 15, which is weaker than any one of the springs 9. When bevelled articles, for example, stiffeners, are to be buffed the carrier as a whole is prevented from rising by a latch 17, which is mounted on a bar 18 secured to the work-table 26 and is turned to engage a rod 20 engaging the carrier, the members 1 then yield individually to accommodate the varying thickness of the work. For operating upon uniform work, for example, soles or insoles, the latch 17 is turned to an inoperative position and the carrier 8 yields as a whole. The feed rolls 52 are carried by a frame 24 movable, under the action of springs 50, upon rods 19 carried by the worktables. When operating upon work of uniform thickness, latches 21 upon the carrier 8 are turned so that they are engaged by pins 23 on the frame 24, the feeding-means then, by its engagement with the work, limiting the approach of the pressers 1 and the buffing-band; when the latches are turned out of the path of the pins, the above limiting action ceases to function. Auxiliary feed-rollers 25 are provided between the main feed rollers 52 and the pressers, the work being supported under the rollers 25 by projections 27 on the work-table 26. Specification 11999/14 is referred to.

Title: Improvements in or relating to devices for performing arithmetical operations
IPC: G06F7/50
Filed: 1951-08-23
Abstract: 732,902. Digital electric calculating-apparatus. COMPAGNIE DES MACHINES BULL. Aug. 23, 1951 [Jan. 4, 1951], No. 19945/51. Class 106 (1). Electronic serial operators for addition or subtraction of binary operands A and B, the digits 1 and 0 of which are represented by the presence and absence of impulses at periods r each of which is marked by a control impulse, comprise a first bi-stable trigger circuit receiving on a symmetrical inlet the A-and B-impulses through elements producing different delays smaller than a period r, and controlling an output gate, a second carry-registering trigger circuit, a carry feedback circuit between the second trigger circuit and the inlet of the first trigger circuit including a delay element, and means for applying the control impulses to a resetting inlet of the trigger circuits, and to the output gate whereby a train of output impulses representing the required sum of difference is transmitted by the gate. In the adding circuit shown in Fig. 2, series-connected trigger circuits 20, 21, e.g. of the Eccles-Jordan type, register the sum and carry digits respectively and for a " 1 " registration, open gates 22, 23. Timing impulses at ET, coinciding with the numberrepresenting digit pulses applied at EA, EB, are applied to the gates to produce sum pulses at S (A + B) and carry impulses on line 31, and are also applied to the triggers through short delay 55 so as to reset them at the end of each digit period. The carry impulses and the digit pulses at EA, EB, are applied successively to the input of trigger 20 due to different delays t - 3t, where t = “p. Other adding circuits are described in which the gate 23 is omitted; and in which three numbers are added by, three series-connected triggers 20, 21, 40, Fig. 5 (t = 1/6p). Fig. 3 shows a subtracting circuit in which the trigger. 21 has a symmetrical carry input 37, and asymmetrical inputs 33, 35 by which the trigger is switched from one stable state only. In this instance t=<SP>1</SP>/ 5 p. A modified subtracting circuit is described in which only three delays are employed and an additional gate in the input to trigger 21 is controlled by trigger 20. Combined devices which can be adapted to perform either addition or subtraction are mentioned. Specification 679,993 is referred to. Reference has been directed by the Comptroller to Specification 706,436.

Patent GB-601706-A (GB)
Title: Improvements in and relating to the dyeing of cellulose esters
IPC: D06P1/651
Filed: 1945-08-10
Abstract: Cellulose esters are dyed by subjecting the esters to a preliminary swelling treatment by complete impregnation with a mono-ether of a dihydric alcohol and thereafter treating with a dyestuff, or a component thereof, which has no affinity or only a low affinity when applied from a cold dyebath in the absence of the preliminary swelling treatment, e.g. direct cotton and wool dyes, sulphuric acid esters and/or ethers of leuco vat dyes. Cellulose esters after the preliminary swelling treatment may be dyed with a vat dye from a morpholine/hydrosulphite bath, or a dyestuff coupling component may be applied, e.g. a naphthol which is coupled with a diazo compound, e.g. by printing with a diazonium salt paste.  The cellulose esters may be swollen by immersion for a short time in a mono-ether of a dihydric alcohol at an elevated temperature, e.g. at 40 DEG  to 50 DEG  C., followed by an optional washing with water and the esters may be dyed without drying.  Resists to the action of the swelling agent may be applied locally to the cellulose esters before the swelling treatment, and after dyeing with a dye which normally has no affinity for the esters, the esters may be dyed with a dye having normal affinity for cellulose esters.  In examples: (1), (5), (6) and (7) cellulose acetate fabric or satin is swollen by immersion in the mono-ethyl ether of ethylene glycol or one minute at 45 DEG  C., and is dyed with Solway Purple RS, Chlorazol Fast Yellow B and Scarlet 4BS, Soledon Orange RS, Solacet Brilliant Blue BS or Duranol Brilliant Blue B; (2) and (8) cellulose acetate satin, swollen as in (1), is washed with water and dyed without drying with Neolan Orange G or Naphthol AS (Brenthol AS), and in the latter case the naphthalated acetate is first printed with a paste comprising Brentamine Fast Red X3GL Salt, water and gum tragacanth mucilage followed by a second print of a similar paste containing Variamine Blue Salt FG; (3) and (4) cellulose acetate locknit and fabric comprising a mixture of cotton and cellulose acetate are swollen as in (1) and are dyed from a morpholine/hydrosulphite bath containing Caledon Red and Caledon Brilliant Violet R respectively; (9) cellulose acetate satin is printed with gum arabic or British gum and is then swollen and dyed as in (1) or (2) with Caledon Yellow 5GKS, Solway Green G, Soledon Orange RS or Neolan Navy Blue 2RL.
