Title: Improvements relating to warp knitting machines
Inventor: PORTER ALLAN WILLIAM HENRY
IPC: D04B15/54
Filed: 1955-02-04
Abstract: 795,532. Knitting-machines. F.N.F. MACHINERY MANUFACTURING CO., Ltd. Jan. 25, 1956 [Feb. 4, 1955], No. 3459/55. Class 74 (2). A flat warp knitting-machine has a draw-off mechanism comprising a pair of draw-off rollers 69, 69a positively rotated always in directions which are opposed but which are reversible relatively to the direction of rotation of a take-up roller 70, so that, for a constant speed of rotation of the draw-off rollers, the takedown tension may be given any of four values by taking the fabric around the rollers in the desired one of the modes shown in Figs. 12- 12d. The reversal of the sense of rotation of the rollers 69, 69a in changing between modes 12a and 12d on the one hand and modes 12b and 12c on the other, is secured by swinging an arm 88 around a driving gear 84 until that gear drives the desired one of intermeshing roller gears 82, 83 through an idler gear 89. The main frame of the machine comprises a bed 1, carrying the moving knitting elements, and a beam 2 supporting the warp beams 7, 7a. The beam 2 supports pillars 4, 5, 6, which in turn support the warp beams. The beam 2 is supported on only two feet 3, arranged at what would be the outermost points of zero slope on the beam if it were simply supported at those points. The pin jointing of links which provide lateral support in one direction for the pillars, ensures that the whole vertical load from the warp beam assembly shall be transmitted to the beam 2. Shafts 24 (not shown), 25, bearing the eccentrics actuating the knitting elements, are driven, at or near their torsional centres, through gear wheels including wheels 34, 43, by a shaft 33 driven by a main motor through a pulley 50, or by an auxiliary motor 38. The auxiliary motor; used to rotate the machine slowly, acts through a reduction gear, a shaft 52 coaxial with the shaft 33 and an automatic clutch. The clutch comprises an internally threaded dog 57 which moves along an externally threaded sleeve 54 keyed to shaft 52 so as to move into or out of engagement with pins 61 on the pulley 50 as the shaft 52 is rotated faster or more slowly than shaft 33: the clutch is thus automatically disengaged when the main motor 37 drives the pulley 50. Each sheet of warps passes over a reed assembly comprising a rail such as 70a, which helps to damp out oscillations normal to the plane of the warp due to the cyclic vibrations of tension bar 65 or 68, and a reed 64 or 67. Each assembly is adjustable in a direction normal to the plane of the warp, as the diameter of the warp beam decreases, by a hand wheel 80 and pinion, nut and lead screw arrangements 81, 76, 74. The machine is lubricated by a pump which draws oil from a sump enclosing the driving shaft and delivers it to the bearings, the oil then draining back to the sump. The sump, of semi-circular cross-section has, along its sides, lengths of bar which serve as handles and as attachments for pivoted hook bolts by which it may be secured to the machine bed. Specification 524,969 is referred to.
Patent GB-1076332-A (GB)
Title: Improvements in and relating to the dyeing and finishing of textile fabrics
IPC: D06B23/04
Filed: 1965-01-27
Abstract: In a method of dyeing and finishing material, particularly knitted fabrics, the material is conveyed through the treatment zone by means of endless flexible tenter bands which together with the material pass over at least one roller in the treatment zone. The edges of the material are impaled on the pins of the tenter bands, the bands are then turned so that the pins project outwardly, and the bands and material are in substantially the same plane.  The bands with the material pass first through a scouring device comprising two rollers (19) and (20) having rollers or brushes spaced around their circumferences to achieve a beating action, Fig. 1A (not shown).  The liquid in the scouring device may be water or a spirit solvent.  The excess liquid is removed and the material is conveyed round a perforated rotating drying drum (22), through which hot air circulates.  The material may then be heat set in a blanket calendering device (27) followed by immersion in a dye bath (31). Excess dye liquid is removed prior to passage of the material through a steam treatment chamber (33).  The material is subsequently washed by means of a spray pipe (35), the excess liquid being squeezed of by rollers (36), dried by passage over a perforated rotating drum (37) and cooled by means of a fan (40).  The material may then be rolled or folded, the tenter bands returning to the feed end of the apparatus.  The tenter bands, one at each side of the fabric, may diverge subsequent to the attachment of the material to further tension the material.

Title: Circuit arrangement for automatic telephone systems for metering connections of different grades according to time and zone
IPC: H04M15/10
Filed: 1937-02-12
Abstract: 486,802. Automatic exchange systems. MIX & GENEST AKT.-GES. Feb. 12, 1937, No. 4304. Convention date, Feb. 13, 1936. [Class 40 (iv)] Apparatus transmitting metering impulses in accordance with zone and duration is provided in common to a number of junctions and is associated with a particular junction on termination of a connection. Two sets of common apparatus may be provided each normally serving a particular group of junctions but capable of serving the other group in the event of a fault arising. Normal operation. Common apparatus Zg1 normally serves a group of 10 junctions and when the apparatus is in order, relay Y is normally energized. On the termination of a call over one of the junctions ZZ, relay F operates over wire a<1> energizing relay E(i) which connects up stepping magnet SM of finder S. When the junction is found, relays P, K operate and magnet AM steps switch A under the control of relays J, W. During the stepping of switch A, metering impulses are sent out over wire b<1> at contact j<1> the operation continuing until relay H operates over wiper t of a time-recording switch, one of wipers a<I> .. a<IV>, and wiper z of a zone-recording switch. Relays E, F, P are then released and switch A returns to normal. A relay N controlled by clock contacts 241a may vary the tariff at night. If the connection is released within the time for which no charge is made, relay H operates immediately over wiper t in position 0. The common apparatus may also contain the zone-determining switch which is then set in accordance with digit switches associated with the junction. Irregular operation. If fuse Si blows, or key Sp is opened, relay Y releases. The second set of apparatus Zg2 contains a relay G which operates when a metering condition arises and the normal apparatus is out of action. If, for example, apparatus Zg2 is faulty, ground over contact f2 of a junction in the second group operates winding G(i) in series with relay E of Zg1. Contact g2 renders the junctions of the second group accessible to switch S over wiper s<II>, and other contacts of relay G connect the time and zone wipers of the second group to switch A. If the switch A continues to advance to position 49, due, for example, to a wiper connection being broken, contacts a3 are closed to hold relay W operated and operate an alarm ZKL. Statistical metering. When relay H shortcircuits its upper (high-resistance) winding, meters R7 .. R10, R1 .. R5, operate to register the number of calls of a particular duration and to a particular zone, respectively. Meter R6 registers the calls which are released within the no-charge period. Meter Jz registers the total number of metering impulses sent out by the apparatus.
