Title: Improvements in drawing heads for spinning fibres
IPC: D01H5/26
Filed: 1937-02-24
Abstract: 488,302. Drawing-heads for spinning- machines. KLUFTINGER, H. Feb. 24, 1937, No. 5525. [Class 120 (ii)] In drawing-heads with endless belts passing around the second foremost bottom roller, the belt is passed around a guide roller close to the nip of the front rollers, and tension means bearing against the lower run of the belt acts in conjunction with the guide roller to tension the belt sufficiently for it to be driven by the bottom roller alone, whereby the top roller may be dispensed with or an unweighted passage roller used. One or more passage rollers may be mounted on the tape to provide suitable retarding points for the fibres of a blend yarn. A bridge-member 4, comprising a series of bearing supports connected by supports 5, Fig. 3, is provided with recesses for needle rollers 9, 10 so arranged that, when it is inserted between the slide 2 and the front roller bearing, as shown in Fig. 2, and the slide is adjusted, the belt is guided and tensioned. The bridge-member enables a drawing-head of the gripping type to be readily adapted for a belt. The bearings of the roller 9 are open so that if a lap is formed or the belt is rotated reversely it is lifted and the belt rendered inoperative. The guide roller may be resiliently mounted or may be in the form of a spring 15, Fig. 8, the bridgepiece 51 being provided with bearings for a roller 91. The bridge-piece may be adjusted by distance pieces in front or behind it. If long belts are used a separate table 12, Fig. 7 is provided to support the top roller 13, the belt ballooning at 14 between the roller 13 and the bottom roller.

Patent GB-950913-A (GB)
Title: Circular, independent needle, knitting machines
IPC: D04B15/54
Filed: 1962-02-14
Abstract: 950,913. Knitting machines. DRAPER CORPORATION. Feb. 14,1962 [Feb. 20, 1961], No.5622/62. Heading D1C. A circular knitting machine having at least one feeding station with a plurality of yarn feeding fingers thereat and a continuously rotating cam drum controlling operation of the feeding fingers, has further means for controlling the position of the yarn fingers including locking members, one for each yarn finger, each acting directly upon a corresponding yarn finger and intermittently actuated pattern means operating the locking members. Sixteen yarn fingers 23 at a feeding station are operable by levers 41 either by a primary control comprising wires 44 from a main pattern drum or by a secondary control comprising levers 45 and an end drum 49. A shogging mechanism 50 effects engagement of each lever 45 with one or another of cam rows on the drum 49. Each yarn finger is lockable in its inactive position by a lever 107 (see Fig. 8) spring biased to move its notch away from the tip 112 of the yarn finger, but held against the tip when so required by one of a set of plungers extending between the locking member and a pattern means. This means may comprise a pattern card 74 extending round drums 66,72. Drum 66 has slots 68 corresponding to perforations 75 in the card and is rotated by a pawl 76 actuating a ratchet wheel 56 attached to the drum. The pawl is pivoted to a plate oscillated by the reciprotation of a plunger 81 co-operating with a cam 85 on a disc 84 (Fig. 2). A ratchet wheel shield 57 is movable over the ratchet teeth to vary the incremental advance of the drum, the position of the shield being altered by a link 87 and follower 89 actuated by a pattern disc mounted on the drum 66 and provided with frangible butts 92. The drum is frictionally braked. The ends 121 of the plungers 120 are withdrawn from the drum and pattern card when the drum is about to be advanced, by an arm 125 moved by linkwork and a cam 134 on the disc 84. When the arm 125 returns the plunger ends 121 press against the card, and the presence. of a perforation therein allows the corresponding plunger to move into a slot 68 to free its locking member from that yarn feeding lever. In a modification (Fig. 5, not shown) the drum 66 and pattern card 73 are replaced by a series of pattern discs having frangible butts. The plungers may then be replaced by sliders having camming ends, in place of the ends 121,to co-operate with those butts (see Figs. 12-17, not shown). In knitting stockings only a fraction of the circumference of the card or discs are required for each stocking so that a number of stockings may be knitted before the pattern starts to repeat. Thus, stockings knitted on the same machine may have variations in the colour effects. Specifications 519,867, 738,737 and 770,639 are referred to.

Abstract: 1,165,131. Pipe connections. J. & E. HALL Ltd. 8 Feb., 1967 [9 Feb., 1966], No. 5624/66. Heading F2G. [Also in Division F4] Apparatus for connecting a bulk cargo container to an air supply duct includes a thermally insulating, extendible duct 8 which joins the supply duct to an apertured sealing plate 2, and power means for extending and retracting the duct. In the figure, the duct comprises a bellows divided by a membrane 9 to connect air-supply and return ducts S, R to apertures 3, 4 in the plate which carries a gasket 12 for sealing engagement with the inlet and outlet ports of the container. Hydraulic or pneumatic rams 5, or an electric motor combined with a rack and pinion or a drive screw, extends the apparatus beyond a protective cowl 13. In modifications, (a) the plate is provided with two circular apertures and is extended by a single ram, and (b) the extendible pipe comprises a rigid tube slidable within a housing the volume between the tube and housing being divided into two regions, to which fluid pressure is alternately fed to provide the extending and retracting movements of the plate; a compression spring is located in one of the regions to bias the tube into the extended or retracted position. Automatic actuating means may be employed, e.g. a switch connected in circuit with the fluid supply means to the rams 5.

Class 145 A hack saw frame 1 has an extension 2 which is reciprocated in a slide block 4 by a .rocking arm 26 oscillated by a crank pin 23 and slider block 24 and the shaft 19 carrying the crank pin is rotated through a lay shaft 15 from a prime mover 7 such as an electric motor; the motor drive means and slide block 4 are all pivotable on trunnions 47 so that the saw 3 bears down by gravity on the work. A pair of spaced side plates 5 attached to the slide block support the motor 7, lay shaft 15 and crank shaft 19 and the pivot 27 for the rocking arm 26 is supported by another side plate 45 also attached to the slide block. For tensioning the belt or chains 12, 21, the lay shaft bearings are adjustable in elongated slots 40 by a screw 43 and the motor' can be pivoted on its support bolt 8. The trunnions 47, which rotate in bearing holes in an arch-shaped bracket 46 welded to the frame 33, are carried by plates 48 that can be slightly adjusted relative to the guide blocks 4 by means of bolts 49 engaging in elongated slots 50. When the saw frame is lifted from the work, it is held in the raised position by a latch 29 engaging a catch 30 on a lever 31 and, when the catch is released, a dashpot 28 ensures the gradual return of the saw to the work. The work support 35 is vertically adjustable.

Inventor: MERIAN ERNEST
IPC: C09B29/08
Filed: 1961-02-16
Abstract: The invention comprises monoazo dyes of formula <FORM:0971167/C4-C5/1> wherein x is a chlorine or bromine atom, y is a hydrogen atom or a methyl or ethyl radical, R1 is a methyl or ethyl radical and R2 is a mono- or di-hydroxy-alkyl radical containing 1-3 carbon atoms which may be etherified with C1-C6 alkanols or esterified with C1-C6 alkanoic acids. The dyes are prepared by the usual coupling reaction from a diazotized 2-cyano-4-nitroaniline and a suitable N : N-di-substituted aniline.  The dyes may be used to colour hydrophobic fibres e.g. cellulose ester and aromatic polyester fibres in red to violet shades.  In an example 2-nitro-4-cyano-6-bromoaniline is diazotized with nitrosylsulphuric acid and coupled in glacial acetic acid with 1-(N-ethyl-N-acetoxyethyl) amino-3-methylbenzene. Further examples are specified.
