Title: Saving motion for control means on flat knitting machines
IPC: G05G21/00
Filed: 1972-02-24
Abstract: 1388575 Knitting machines UNIVERSAL MASCHINENFABRIK DR RUDOLF SCHIEBER KG 24 Feb 1972 [10 March 1971] 8588/72 Heading D1C In a saving motion arrangement for controlling the stepping of movable control means, e.g. control cards or control chains, a decade counter with sequentially activated output connections and a decade counter with input connections are arranged along different sides of a distributor so that plug connections can be made at intersections for producing a control signal at given counts, the count of the counters being changed by movements of the control means whose stepping operation is altered by the control signal. Switch 1, mechanical or electronic, is switched, e.g. by a control card, once in every pattern repeat and via gate 2 a pulse is fed to decade counter 3 for "ones" and thus is advanced one step causing a pulse to be given to outputs 0'-9' in succession. The eleventh pulse resets counter 3 and passes a pulse through gate 4 to decade counter 5 for "tens" and connects outputs 0"-9" in succession to output 15. Outputs 0'-9' and 0"-9" are connected respectively to vertical and horizontal strips 8, 9 mounted in separate planes. Thus a strip 8 e.g. connected to output 6' can be connected by a plug 10 containing a diode 1 to a strip 9 e.g. connected to output 4". Thus, when a pulse goes to 6' and 4' is connected to output 15, a signal occurring at 15 extinguishes the advancing function preprogrammed in the control card and produces forward switching and it continues to the next card. As shown, advancing controls take place via gates 16, 17, 18, 19 which respectively provide two steps forward, one step rearward two steps rearward and one step forward. Gates 16 to 18 are controlled by the inverting of the signal of the connection 15 i.e. no signal at 15 and they switch as set. Gate 19 is connected  via diode 20 with connection 15 so that if a signal is present at connection 15, gates 16  to 18 are blocked and "one step forward" is connected. When a new item is to be started, switch 21 is actuated by a control card and counters 3 and 5 are returned to 0. The arrangement may alternatively be reset by a special plug which is so long that it engages a contact plate 28 and is such that, when this point is reached on the counters, the reset process is initiated. Manual switch 29 allows the counters to be moved step by step. Manual switch 30 acts like switch 21.

Filed: 1963-03-05
Abstract: A fertilizer containing ammonium phosphate is obtained by treating phosphoric acid, alone or in admixture with sulphuric acid, with ammonia to a pH in the range 5.5 to 6.7, such that a fluid slurry is obtained containing 5-25% by weight of water and having a temperature in the range 100 DEG  to 130 DEG  C.; mixing the slurry at a temperature in this range with one or more acidic substances selected from H3PO4, H2SO4, single superphosphate, and triple superphosphate, the acidic substance containing not more than 38% by weight of water based on the weight of the acidic substance, in such proportions as to give a pH of 4.0 to 5.0; said mixture solidifying to a hardenable solid which contains less than 10% by weight of water based on the mixture, and which can be comminuted.  The preferred pH range of the ammonia treated acid is 5.9 to 6.7 and the slurry preferably contains 10 to 20% by weight of water.  The temperature of the acidic substance is in the range 20 DEG  to 60 DEG  C.  When using H3PO4 alone, it should preferably contain 40% by weight of P2O5 based on the acid but when mixed with H2SO4, the phosphoric acid used should contain 30 to 40% by weight of P2O5 and the sulphuric acid used should contain 90-96% by weight of H2SO4 and a preferred mixture is given as 1 part by weight H3PO4 (as 100% H3PO4) and 0.1 to 0.5 parts by weight of H2SO4 (as 100% H2SO4).  The mixer used in forming the slurry may vary with the physical state of the components, e.g. with a liquid/liquid mix a Venturi mixer is preferred, with a liquid/solid mix, a paddle mixer.  The components are mixed just long enough to form an intimate mixture, e.g. 0.2 secs. with a Venturi mixture and less than a minute for a paddle mixer, the product obtained being allowed to consolidate without further agitation.  The mixture of slurry and acidic material is preferably fed to a vented chamber to solidify, e.g. a Broadfield den, and the solid product may be mixed and granulated with other fertilizer materials, e.g. single or triple phosphate, NH4NO3, (NH4)2SO4, CO(NH2)2, KCl and KNO3, the granulation being achieved by wetting the mix, tumbling the wetted mix at elevated temperature and drying.

Title: Thread controlling mechanism for sewing machines
IPC: D05B47/00
Filed: 1961-03-14
Abstract: 903,112. Sewing-machines. SINGER MANUFACTURING CO. March 14, 1961 [April 1, 1960], No. 9277/61. Class 112. To achieve uniform stitch formation throughout a wide variation in sewing speed a lockstitch machine includes a needle thread-tensioning device having a frictionally braked rotatable thread receiving drum 50, a first thread guide 51 and a second thread guide 52 engaging the needle thread between the tension device and the needle, and a thread takeup member engaging the bight of thread between the guides and having a path of motion during the initial expansion of the thread bight during each stitch forming cycle which is substantially in the direction of the thread extending from the first thread guide to the take-up element. Further, the means for applying frictional resistance to the turning of the thread tensioner drum accounts for only a minor fraction such as one-fifth of the stitchsetting tension. The tension device is similar to that described in Specification 867,694, and the rotary take-up has a leading edge 57 which controls the thread during the expansion of the bight and a thread confining finger 59. From one stitch to the next the amount of thread consumed in one stitch is drawn through the tension device by the take-up. The sewing machine shown avoids increased tension in the thread at stitch-setting time, towards the end of the expansion of the thread bight by the take-up which increased tension would otherwise occur as the sewing speed increased due to the effects of both decrease in the time for drawing the thread and to the inertia of the thread drum, by reducing, as the speed increases, the increment of thread drawn through the device at that stitch forming time. The limb of the thread extending from guide 51 to the take-up element, being in the direction of motion of the element, is suddenly engaged at the early portion of the " taking-up " motion and an impact load, increasing with the sewing speed is applied to the thread. This load then draws through the tension device increasing increments of thread as the speed increases, to reduce the magnitude of the increment of thread required at stitch-setting time.
