Title: Improvements in machines for winding yarn, thread or other material
IPC: B65H54/24
Filed: 1919-05-27
Abstract: 142,326. Abbott, E. J. May 27, 1919. Knot-tying devices.-In the winding of yarn, thread or other material, from one package on to another, especially from small spools or bobbins into a larger cop or cheese, mechanism is provided which will operate automatically immediately upon and as a direct consequence of the cessation of the supply from one bobbin, to attach the leading end from a reserve bobbin to the end of the yarn passing to the winding- mechanism. The tying and severing device employed may be utilized when a slub or enlargement occurs in the yarn &c. to cut out the slub or enlargement in the yarn &c. and to tie together the severed ends of the yarn. as described in Specification 142,325. The tying and severing device comprises a blade 107, Figs. 11 and 13, pivoted between two fingers 111, 112 at the end of a sleeve 105 mounted on a bushing 103 carried by a framework 52. The stem 105 is driven from a gear 57<1> on a shaft 57, which is put into operation automatically at the required time. A tail-piece 106 on the blade 107 works in an eccentric recess in the bushing to open and close the blade. The stem rotates twice during one operation. The yarns are laid by arms 99, 86 against the stem 105 in the angle formed by the fingers, and are wound during the first revolution once around the stem close to the bases of the fingers. During the next revolution the yarns are caught between the fingers 111, 112 and the blade 107, which, on closing, cuts away the ends and grips the yarns. The arms 86, 99 then move away and draw the yarns to pull. the knot from off the stem and draw it tight.

Title: Improvements in the balancing of reciprocating engines
IPC: G01M1/12
Filed: 1942-09-22
Abstract: 560,955. Balancing reciprocating engines. DOXFORD & SONS, Ltd., W., and PURDIE, W. H. Sept. 22, 1942, No. 13343. [Class 7 (ii)] An oil engine of the vertical opposed-piston single crank-shaft type of the kind having a scavenge pump 20, Fig. 2, driven from the crank-shaft and situated in the middle of a row of cylinders, has the weights of all the lower (or upper) pistons modified, half being increased and half decreased, all by the same amount and the position of the scavenging crank 22 is arranged so that unbalanced primary forces for the complete engine remain at zero while the unbalanced secondary vertical forces are reduced to a small valve. In a four-cylinder engine, Fig. 2, each cylinder has two pistons coupled to a single crank-shaft 19 and the scavenge pump 20 is arranged between cylinders 2 and 3. The reciprocating weight of the pump is balanced by reducing the weight of lower pistons 26, 27 (cylinders 3 and 4) conveniently by fitting thinner piston skirts and increasing the weight of the other lower pistons 24, 25 by' the same amount by adding weights 28, 29. The phase of the pump crank relative to the cylinder cranks is shown in Fig. 3 and the added or subtracted weight is equal to #2 / 4 = 353, of the reciprocating weight of the scavenge piston assembly. In a modification, Figs. 4 and 5, the lower pistons are secured to cranks arranged at 60 degrees. The scavenge pump crank coincides with that of cylinder No. 5 and in order to balance the scavenge pump assembly when the pump has the same stroke as the lower pistons, the weights of the lower pistons in cylinders 1, 5 and 3 are reduced by a quarter of the reciprocating weight of the scavenge pump assembly 31 and the pistons of cylinders 2, 4, 6 have their weights increased by the same amount. If the pump has a different stroke from the lower pistons, the added and subtracted weights are modified aceordingly. In other examples, the modification of the weights may be applied to the upper set of pistons or to both sets of pistons.

Title: Method of and composition for the treatment of water
IPC: C02F1/64
Filed: 1936-05-12
Abstract: Compounds of iron and manganese are removed from water by filtration through a bed of granules comprising a mixture of cement and particles of manganese dioxide or triferric tetroxide, the granules being of a size to pass through a 10 mesh screen and to be retained on a 60 mesh screen.  The treatment also removes hydrogen sulphide from the water.  The oxide may be formed into granules in admixture with cement or particles of the oxide may be held by cement in the pores or on the surfaces of a granular base material such as pumice, lava, earthenware, porcelain, sand, slag, coke or charcoal.  The cement may be Portland cement, a hydraulic cement containing a large proportion of alumina, rubber latex, phenol condensation resins, pitch or asphalt.  In filtering, the bed of granular material becomes clogged by precipitate and is cleansed by back-washing.  The granules should be of such size and density that they are suspended in the back-wash stream.  The base material may comprise a water-softening agent such as base-exchange compound.  An example of the preparation of suitable material is described according to which a mixture of finely divided pumice, powdered pyrolusite, alumina cement and water is cast into small blocks which are crushed into granules when the cement has set.  In another example finely divided zeolite and pyrolusite are cemented together by rubber latex or artificial resin. If the water under treatment is deficient in oxygen it may be aerated or treated with oxygen or ozone prior to its passage through the bed. If the water contains hydrogen sulphide the efficiency of the bed may be maintained by periodic treatment with a solution of potassium or sodium permanganate or by continuous addition of such permanganate to the water.  The Specification as open to inspection under Sect. 91 states that the finely-divided active material may be cemented to larger surfaces, such as coarse rock, large sheets or boards, which are arranged in the water stream.  This subject-matter does not appear in the Specification as accepted.

Abstract: 1,065,632. Winding bobbins. W. REINERS. April 3, 1964 [April 5, 1963], No. 13841/64. Headings D1D, D1F and D1J. Spinning packages are prepared for unwinding by the thread end being introduced into the bore of the bobbin tube and then at the winding station being pneumatically removed ready for the knotting operation. As shown in Fig. 1 wound packages, which have a transfer tail at the foot of the package, are fed on to rolls 61, 62. The tail is pneumatically removed through pipe 218, Fig. 4 and as pipe 218 then pivots away from the tube the thread is severed. As the tube is rotated by the rolls the back turn is sucked into nozzle 160 till the bobbin tip is reached, A leaver 207 then pivots to pull the thread across shears 210 while spike 205 contacts the package to prevent further unwinding. Pipe 218 pivots back on to the end of the tube to cause the thread end to be sucked into the other end of the tube. The package is then deposited onto an empty trough on chain 7. As troughs 37 Fig. 2, pass a winding station, they pivot a lever 43 which if trough 25 is empty causes rod 42 to move to the right so that ring 47 releases flap 39 and the package falls into trough 25. When ejector 21 moves an empty tube from peg 19 onto belt 22 a suction tube 30 moves over the end of package K' in trough 25 to withdraw the thread end. Peg 19 then moves clockwise to receive package K', and as it moves back anticlockwise, a transfer lever 20 also moves anticlockwise taking the yarn into the region of thread seeker 16. Instead of having a transfer tail at the base of the bobbin, there may just be a return winding.
