Title: Improvements in the manufacture of knitted fabrics
IPC: D04B35/02
Filed: 1946-05-10
Abstract: 633,624. Knitting. PARES, J. J., and DAROCA, S. S. May 10, 1946, No. 14132. Convention date, Dec. 7, 1945. [Class 74 (ii)] A needle 3 has an inclined part 4 ending in a rigid hook 5, and a groove 6 in which can slide a member 7 or 17 having an upwardly directed hook 8 or a downwardly directed hook 18. When the needle, with a newly fed yarn 12, begins to descend, the previously formed loop 11 is caught by the hook 8 or 18, the member 7 rising, or the member 17 descending. slightly. As the needle continues to descend past a knocking-over member 1, its hook carries the new yarn through the old loop 11, which is now released by a descent or ascent of the member 7 or 17. The needle is of rectangular cross-section and the bottom of the groove 6 is vertically in line with the point of the needle hook. The travel of the needle need be only slightly greater than the length of the part 4 and thus the needle may be relatively short and stiff and a greater speed of operation possible.

IPC: B41J19/76
Filed: 1928-05-14
Abstract: 317,510. Alexander, F. May 14, 1928. Line-spacing mechanism. - The line-spacing lever 13, Fig. 2, rocks a shaft 10 provided with a tooth 14, Fig. 8, which is guided by a slot in a bearing-sleeve 9 and engages an arm 15 pivoted on a lever 18 carrying a pawl 21. The pawl is normally horizontal and co-operates with a ratchet-wheel 8, but can be turned into the position shown in Fig. 2 when out of use. The arm is secured to a pin 16 pivoted in lugs on the lever. The lever is pivoted on a pin 19 and engages a returning-spring 20. The spacing- regulator consists of a curved member 23, Fig. 2, resting on the bearing-sleeve and formed with a finger-piece, and a lug which normally holds the pawl out of engagement with the ratchet-wheel. The member is rotatable to vary the position of the lug and is retained by a screw 24 which passes through a slot. The above-described mechanism is provided at each side of the carriage, and to permit employment of the same line-spacing lever with either mechanism, each shaft 10 is formed with a slot and grooves for engaging a mortise and cross-pins on the line-spacing lever. The ratchet-wheels engage detent-rollers 26 on springs 27 engaging projections 30 on a shaft 28 which can be rocked by means of a finger-piece 29 to the detent-rollers. Specification 315,044 is referred to.

Title: A process for the production of low carbon iron or steel

Filed: 1938-05-16
Abstract: 514,950. Decarburizing iron &c. WESTBERG, S. May 16, 1938, No. 14532. Convention date, May 18, 1937. [Class 72] In the production of iron or steel having a low carbon content, the molten metal to be decarburized is subjected to a highly oxidizing treatment, e.g., by Bessemerizing, to obtain a mass containing substantially sufficient oxygen present therein as to be capable of reacting with the residual carbon in the metal and then subjecting the metal in granulated form to a decarburizing heat treatment in the solid state preferably in the presence of hydrogen or a hydrogen-containing atmosphere. If the oxygen content in the mass is not sufficient, the decarburizing may be carried out in the presence of oxygen or an oxygen-containing atmosphere. When hydrogen is used, elements such as aluminium, calcium, magnesium or silicon which will regenerate hydrogen from the water vapour formed may be present. After treatment, the decarburized metal may be further heated, preferably in an inert atmosphere, to melt the same.

Abstract: 744,925. Automatic control systems. ADDISON ELECTRIC CO., Ltd. May 4, 1954 [May 22, 1953], No. 14540/53. Class 38 (4). In Fig. 1 change in diameter of a rubber or plastic insulated cable being produced by a continuous extrusion process is detected by a contact gauge L which energizes a relay O or U according to whether the cable is oversize or undersize respectively. A relay F or S is then energized to run a motor I in the appropriate direction to correct the size by adjustment of the haul-off speed or the extruder screw speed. Auxiliary contacts 03, U3, Fig. 2, associated with relays O and U initiate the continuous operation of a relay A, the operating time of which is determined by a network R1, C1, the release time of which is determined by a network R2, C1 and the interval before the commencement of the next cycle of operation of which is determined by a network R3, C3 associated with a relay B. Contacts A4 of relay A cause intermittent operation of motor I and the timing is adjusted manually or automatically so that the operation of motor I is suited to the particular operating conditions, e.g. diameter of the cable or the time taken for the cable to pass from the die face to the gauging unit. The Specification also refers to modifications involving magnetic or capacitative gauging, and timing controlled by bimetallic switches, thermionic valve circuits, contacts operated by a roller running on the cable, and a temperature-variable resistance responsive to a tachometric voltage dependent on cable speed. Application to the extrusion of metal or plastic wire, strip and sheet is referred to.
