Title: Improvements in or relating to stop motions for knitting machines
Inventor: SHORTLAND ARTHUR
IPC: D04B35/18
Filed: 1950-10-02
Abstract: 703,846. Knitting-machines. MELLOR, BROMLEY & CO., Ltd. Aug. 22, 1951 [Oct. 2, 1950No. 24032/50. Class 74 (2) A stop motion for a knitting machine comprises a detector 1a adapted to be held, against a spring 12, in the vicinity of the needles by a catch member 6 engaging a recess in the side wall of a casing 2. When the end 1b of the detector is engaged as a result of a fault or abnormality in the knitting it is moved aside in the casing so as to release the catch and projected upwardly so that an electrical contact 9 carried by it engages a similar contact 16 fixed to the casing thereby energizing an electrical circuit which effects stoppage of the machine. To enable adjustment of its position to be made, the detector is screw threaded in the catch member 6. As described, a number of detectors in their casings may be secured to a cylinder and dial machine and connected to a common electrical circuit.

Title: High temperature fluid heater
IPC: F22B29/02
Filed: 1960-07-11
Abstract: 901,577. Hot-water boilers. BABCOCK & WILCOX CO. July 11, 1960 [Oct. 6, 1959], No. 24143/60. Class 64 (1). In a fluid heater particularly for high temperature and high pressure water comprising a furnace 10 having an outlet 32 for the hot gases, a convection gas-pass 29 and a device such as a stoker 11 and a travelling grate 14 for introducing fuel into the furnace, tubes 26, 26A, 26B and 50 line the front, rear and side walls of the furnace and the convection gas pass. Fluid enters through an inlet which is connected to the header 27, and flows upwards through the tubes 26, 26A, 26B to the header 31. External downcomers 33 then deliver the fluid to an intermediate header 34 from which it flows through the horizontal convection heating tubes 35 to the header 36. The fluid then passes through the downcomers 37, 38 and 42 to the headers 40 and 41 positioned in the side walls of the furnace, which assure distribution to the side and rear walls. From these side tubes the fluid is delivered to two headers and thence collects in the header 47 and is discharged through the outlet 52. The fluid is circulated by a pump, but should it become inoperative then the natural circulation of the fluid through the tubes by way of the standpipes 53, 54 which connect the side and rear wall headers protects the unit from tube failure. Specification 736,474 is referred to.

Title: An improved boring bar steady for use in the boring of the main bearings of crank cases and the like
IPC: B23B29/02
Filed: 1944-12-04
Abstract: 583,778. Boring-bar machines. MALIA, A. Dec. 4, 1944, No. 24188. [Class 83 (iii)] In a portable boring-bar machine for the main bearings of crank-cases, two brackets 3 are erected on the joint face of the crank-case 1 and support, in slots 3a, a cross-head 6 having a central rectangular recess containing a knurled screw 7 having a chamfer 7a. The chamfered face abuts clamping-pads 8 which project into bores 6a, in the cross-head, arranged parallel to and in a horizontal plane with the joint face. Two threaded studs 6b project from the centre of the cross-head sides and locate in slots 3a ; the studs have nuts 12 and washers 13 to position the cross-head. A central stud 14 is supported in bracket 3 and allows vertical adjustment of the cross-head by means of wheel 16 and plate 15. Two alignment rods 9, 10 fit the bores 6a which are of different diameters to ensure correct fitting of five brackets 11 carried by the rods. These brackets have similar adjusting screws 7 bearing on pads 8 to clamp them to the rods and a lower portion 11a acts as a bearing for the boring-bar. The brackets 3 complete with cross-heads are erected at either end of the crank-case with brackets 11 slidable on rods 9, 10 and the bearing 11a approximately coaxial with the main bearings. Bearing caps 2 are removed from the crank-case, a boring-bar is inserted in the bearing 11 a and the caps replaced minus their bearing bushes. Setting is effected by arranging a flanged half bush in each of the two main bearings beneath bracket 3 and adjusting the cross-head and height of .brackets 11 until it is possible to move the bush completely round the boring-bar. Cross-head is then locked by nuts 12. Remaining brackets 11 can then be positioned and will be in correct alignment due to their common support on the rods. Bores 6a may be arranged in a vertical or other plane and more than three alignment rods may be used.

Variable-speed gearing as described in Specification 194,152 is combined with a combined driving friction clutch and brake for reducing shocks in changing speed. Upon an extension 1<a> of the engine shaft 1 there slides a sleeve 3a carrying the male member 3 of the clutch. The female member 2 with its lining 2a is secured to the shaft 1. Upon the driving-shaft 5 of the change-speed gear is splined a sleeve 4 bolted to the sleeve 3<a>. When the clutch 3 is moved to the right out of engagement against the action of a spring 1<b> by a pedal-lever 6, a brake disc 4a eventually comes into contact with a fixed braking surface 8, upon which the change of speed is carried out.

Title: Improvements in the production of artificial filamentary materials
Inventor: HILL FRANK BRENTNALL
IPC: D01D5/06
Filed: 1953-09-02
Abstract: <PICT:0787558/IV (a)/1> In the wet-spinning of artifical filaments wherein the filaments are drawn from the spinneret through a narrow tube through which coagulating liquid flows, the filaments are drawn through and out of the tube by a godet which makes contact with the filaments at intervals along their length.  The godet may comprise a fluted roller having flutes parallel to its axis, the flutes and lands being approximately equal in width and the edges of the lands being rounded off slightly.  As shown, filaments are spun upwardly from the jet 2 in coagulating bath 1 supplied with coagulating liquid through pipe 4 and gauze 6, which prevents turbulence.  Coagulating liquid passes up tube 7 and is collected in collector head 10, whilst excess liquid adhering to the filaments is removed by pigtail guide 13 and drains over inverted funnel 12 into the collector head 10, as described in Specification 787,556.  The filaments are drawn out of the tube and stretched by fluted roller 14, which may be associated with a skew idler roller (not shown) which may or may not be fluted. The filaments are then passed round skew rollers 17 in washing bath 18.  The invention is of particular value in the extrusion of acetone solutions of cellulose acetate into aqueous solutions of diethylene glycol diacetate or of aqueous acetone, but may be used in other wet-spinning processes, e.g. in the wet-spinning of acetic acid solutions of cellulose acetate, using as coagulant aqueous acetic acid containing a high concentration of a salt such as an alkali metal acetate.  Specifications 720,187, 787,557, 787,559, 787,560 and 787,561 also are referred to.
