Title: Improvements in or relating to the manufacture of hosiery footwear
IPC: D04B9/46
Filed: 1958-03-14
Abstract: 914,306. Knitted fabrics. REYMES-COLE, B. T. R. March 13, 1959 [March 14, 1958], No. 8238/58. Class 74 (2). The foot, heel part and leg of an article of hosiery footwear are knitted mainly or wholly by rotational knitting, at least the heel part being formed at least partly from thermoplastic yarn; part courses are knitted at least at the heel position on the heelward part of the article by continuous rotational knitting with the floats between the ends of the part courses taken up in the fabric within the circumferential extent of the part courses; and the heel is subsequently shaped at least partially by stretching the heel part widthwise on a form and heat-setting. In the region of a line 19, caused by the junction of part courses with the remainder of the fabric when a partial pouch 21 has been formed, part courses of main yarn may, at the heel side, be interposed between complete courses thereof, the lengths of yarn between the ends of the part courses being passed from the back of the fabric, in front of sinker loops 31, and laid in as short floats 28. When splicing yarn is present, as in Figs. 1 and 2, that yarn may be knitted in with and laid in with the main yarn wherever knitting and laying in of the splicing yam occurs. Alternatively, the part courses may be of main yarn only, the splicing yarn being omitted therefrom. In the region of the line 22, when the foot is spliced, the part courses may be of splicing yarn 25 and the floats may be laid in at 26 in front of sinker loops 30 and behind needle loops. Floats of splicing yarn may, however, be knitted in at the next course, as at 29. The toeward portion of fabric may be knitted of stretch yarn, or narrow inserts of reciprocatorily knitted fabric may be included in the region of the heel and/or toe, or a small tuck may be formed in the fabric at the toe extremity, held in place by the seam 23. Specifications 570,180 and 756,841 are referred to.

Abstract: 1417460 Steering mechanism ZAVODY TAZKEHO STROJARSTVA GENERALNE RIADITELSTVO 21 Fob 1973 [22 Feb 1972] 8457/73 Heading B7H A power assisted steering mechanism includes a power circuit 1 and a control circuit 2, the arrangement allowing the power cylinder 10 to be operated by fluid from the control circuit in the event of power circuit failure. The power circuit includes a pump 3 connected via line 6 in a spool valve 7 which controls supply to the cylinder feed lines 8, 9. The control circuit includes a steering wheel actuated metering pump 18 and pressure lines 20, 21 connected to a feed back cylinder 22 and actuating chambers 24, 25 of the valve 7. A valve 26, Fig. 5, interposed between lines 20, 21 and lines 8, 9 is subject to the pressures in lines 20, 21 and line 6, and is normally held in the closed position by the pressure in line 6. In normal operation movement of steering wheel 19 causes a pressure differential between lines 20 and 21 and spool valve 7 is moved to connect pump 3 to line 8 or 9. Movement of the steering linkage 14 acts on piston 23 in cylinder 22 to equalize the pressure in lines 20 and 21 and valve 7 is eventually returned. If the power circuit fails, pressure in lines 20, 21 move a spool valve 26 to connect lines 20, 21 to lines 8, 9. Valve 26 may be replaced by two separate spool valves (Figs. 2, 6, not shown) connected between lines 20 and 8 and lines 21 and 9. In another embodiment (Fig. 4, not shown) two separate spring loaded check valves may be interposed between lines 20 and 8 and lines 21 and 9, the opening pressure of these valves being greater than the actuating pressure of the valve 7. In a further embodiment (Fig. 3, not shown) a 3-way spool valve controls the connections between lines 20, 21 and lines 8, 9, this valve is actuated by the pressures in lines 20, 21 but requires a higher actuating pressure than valve 7. In a modified arrangement, Fig. 7, a spool valve 47 controls the normal power circuit connections in positions p and l and the connections between lines 20, 21 and lines 8, 9 in the extreme positions p<SP>1</SP> and l<SP>1</SP>.

[Also in Group II] Shearing.-In a machine for die forging a succession of nut blanks &c. from bar stock the heated stock is successively severed into blanks which are squeezed endwise to loosen the scale from the peripheral faces before scale has formed on the severed end faces to render the blanks substantially scale free. The stock 20, Fig. 3, s intermittently fed from a furnace 21 by rollers 30, 31 against an adjustable gauging stop 33 and is severed by a blade 40 while held between fixed and movable jaws 37, 38, the stop 33 then being withdrawn by a cam 61 to permit the blade 40, which has a spring- loaded blank-gripper, to carry the blank to a position between squeezing dies 51, 55. The movable die 55 is actuated by a cam 60 through an adjustable spring-loaded push rod 50 which, on initial movement of the cam follower 64, causes the blank to be gripped under the pressure of a spring until the blade 40 and gripper are withdrawn, whereupon on further movement of the cam follower the push rod becomes solid and the blank is squeezed to loosen the scale. The die 55 is then withdrawn permitting the blank to drop into a shoot 80 along which it rolls or slides to the nut-blanking position, a slot 81 being provided in the shoot for the release of scale. Blanks are successively fed from the bottom of the shoot 80 to the nut-forming die 111 by a finger 103, Fig. 13, pivoted at 106 in a support 90 which is reciprocated by a cam 91 through a system of levers 93, 95, 97. The finger 103 is yieldingly held by a spring 108 to permit passage of a shaping tool 110, Fig. 16, to the die 111. The tool 110 is reciprocated by a crank 116 with a safetyclutch mechanism and has a central portion 131 which partially forms the hole in the nut, leaving a web 141. Upon withdrawal of the forming tool 110 the nut is ejected by a camoperated pin 130 having passages 134 for directing cooling fluid into the die when aligned with ports in the frame of the machine. The ejected blank is then carried by a second finger 104 on the support 90 of the finger 103 to a die 142 at which position the web 141 is removed by a punch 140 reciprocating with the shaping tool 110. The web 141 drops through an aperture 143 in the frame and the completed blank is stripped from the punch 140 by a stationary stripping plate 145, as the punch 40 is withdrawn. Specifications 695,946 and 696,019 are referred to.
