Abstract: 1,062,741. Knitting machines. MATTHEWS & BIRKHAMSHAW Ltd. Jan. 21, 1964 [Jan. 26, 1963], No. 3337/63. Heading D1C. In order to reduce the number of stitches when changing from a rib welt to plain knitting "loop-doubling" is carried out mechanically by co-operating with a set of needles or points carrying the last course of the rib welt a set or sets of points to effect the sideways transfer of predetermined loops from their needles to neighbouring needles. The reduced number of loops are then run on to a corresponding reduced number of points of a point bar for transfer to a straight bar plain knitting machine. The rib welt on the rib knitting machine is run on to a point bar and removed to a separate machine for the "loopdoubling" to be carried out. As shown, Fig. 1, a modified Cotton's Patent straight bar machine is used as a "loop-doubling" machine, the rib welt being first transferred from a point bar 3 to the needles N of a needle bar 1 by the dipping and raising motion of the narrowing head 2. Spaced points 4, 6 on rods 5, 7 are then brought into co-operation with the needles N and operated with endwise motions in opposite directions, as well as the dipping and raising motion, to pick up and "double" spaced loops as in Fig. 7 to form spaced groups of loops on needles N, each group having end double loops. Groups of loop support elements GP, GP1 on mounting bars 9, see also Fig. 10 (not shown), are then brought into co-operation with needles N and are operated to lift the spaced groups of loops on needles N and close them together on a consecutive number of needles. The point bar 3 is then re-introduced to receive the reduced number of loops for transfer to a plain knitting machine. In a modified arrangement a single bar with spaced loop transfer points is provided but is actuated to transfer loops sideways first in one direction then the other.

Title: Improvements in control devices for data recording machines
Filed: 1958-02-03
Abstract: 879,721. Typewriters etc; strip perforating. INTERNATIONAL BUSINESS MACHINES CORPORATION. Feb. 3, 1958 [Feb. 1, 1957], No. 3444/58. Classes 100(3) and 100(4) In a typewriter or like machine which produces a printed sheet and at the same time produces a record in code form e.g. in a perforated, magnetic or photosensitive tape 34, a control device causes a first code designation, representing a line of data, to be made in the tape, and has a storage device whereby such first code designation is stored until the first data-representing code is made when the stored designation is cancelled; means also operable in response to a further control signal representing the non-delivery or delivery of said data representing code to cause the control device to deliver a second or third code designation according to whether said storage device is set or is reset respectively. A carriage return key CR initiates the first code designation and at the commencement of operations is the only key on the machine which is operable. This key causes three functions (i) mechanical return of the typewriter carriage, (ii) release of the keyboard lock and (iii) energization of a relay to make the first code designation through a code unit 32 and offset FS code in the tape 34. This action is stored by another relay in the memory means 38 and held until a data-representing code is typed or a space key is operated. If the carriage-return key is held depressed no subsequent action results because of an anti-repeat circuit arrangement. A second depression however of the carriage-return key, energizes a line-space relay to line-space the typewriter and a line-space code is entered in the tape. If a line of typing is completed the depression of carriage-return key operates a control relay (70 not shown) and five tape-punch cycles occur to punch end-of-record codes CR, FS, LF, a check code and beginning of record codes in the tape 311. If an error has been made in the line of data entered an error key 16 is depressed and an error memory relay controls functions relating to error identification and deletion, locks the keyboard and conditions circuits for the entry of the beginning of a message code in the tape. To re-enter the line of data the carriage-return key is depressed to provide return of the carriage, effect line-spacing, and unlock the keyboard. Specifications 644,576, 737,751, 840,894, 843,004, and 843,005 are referred to.

Title: Process for dyeing fibres of polyacrylonitriles
IPC: D06P3/70
Filed: 1954-02-09
Abstract: In the dyeing of polyacrylonitrile fibres with azo-dyestuffs which are free from sulphonic acid groups and contain at least one amino group which forms with acids salts which are at most partially hydrolysable in an acid medium, the dyestuff is fixed on the fibre in the form of an amine salt which contains no salt grouping other than such as are formed from the amino groups and acid molecules, the dyeing being fast to light and alkalies.  The salt of the dyestuff base may be preformed and directly applied to the fibres, or it may be formed in situ by adding the acid to the dyebath containing the dyestuff base, or the fibres treated with the dyestuff base may be after-treated, or may have been pretreated, with the acid.  Specified acids are hydrochloric hydrobromic, sulphuric, phosphoric, aminosulphonic, perchloric, methane-sulphonic, benzene-, naphthalene-and cymene-sulphonic, acetic, propionic, chloracetic, oxalic, lactic, tartaric, citric, gluconic (if desired in the form of its lactone), glutaminic, ethylene-diamino-tetracetic, benzoic, 4 - tertiary butyl benzoic, naphthoic, salicylic and phthalic acids. Dyeing, and also the pretreatment and after-treatment, are preferably effected in an aqueous medium to which dispersing agents may be added if necessary.  When the dyestuff contains an -NH2 group, it may be diazotized and coupled on the fibre.  Numerous examples are given.
