Abstract: 816,111. Warp let-off motion for looms. SAKAMOTO, K. Oct. 11, 1955 [April 9, 1955], No. 28974/55. Class 142(2) A warp beam, rotated by ratchet mechanism operated by the slay movement, has its rotation varied in accordance with the movement of a presser arm and also in accordance with the warp tension. A rod 13 pivoted at 14 to the slay 5 rocks arms 11, 12 connected by a movable pin 28 to arms 15, 16, the arm 16 being connected by a rod 39 to the ratchet mechanism 51, 52, The presser arm 19, on a shaft 17, moves in the direction of the arrow a as the yarn unwinds and causes an arm 25 to swing, thereby moving the pin 28 connecting arms 11 and 15 and altering the operation of the ratchet mechanism and the let-off motion. The rod 39 is adjustable connected in a graduated slot in the arm 16 by a pin 38. The rod 39 is connected at its other end to an arm 37 pivoted on a pin 35 and a second arm 36 on the pin 35, and which swings with the arm 37, has a slot 36<SP>1</SP> in which is loosely connected a roller 42 on the end of a rack 41 engaging a toothed sector forming part of the ratchet mechanism. If the warp tension increases, a roller 84 is moved to the right (Fig. 1) and a weight lever 29 rises and lifts a rod 32 carrying the pivot 35. This movement increases the distance between the pivot 35 and the roller 42 so that the movement of the rack 41 is increased and the amount of yarn let-off is also increased. When a pedal 97 is depressed the pawls are disengaged from the ratchet wheel and a shaft 43, connected by toothed gearing to the warp beam, can be turned via a clutch 65, by a hand-wheel 99 on a shaft 61. The warp tension is eased during shedding by a lever 77 operated by a cam 72. The warp is held under tension at beat-up by a cam 71 and an arm 75. The arm 75 has a spring loaded piston 88 which engages a shoe 87 on an arm 86 mounted on a shaft 30 carrying the weight lever 29. The shoe 87 also ensures that the warp is not affected by the weights 31 when the loom is not running.

Title: Improvements in projectiles
IPC: F42C17/00
Filed: 1920-07-10
Abstract: 171,091. Pollak, F. Nov. 3, 1920, [Convention date]. Paper, treating with special materials.-Condensation products are obtained by heating urea, thiourea, or their derivatives with formaldehyde or a polymer thereof in the presence of a base, such as ammonia or pyridine. The initial condensation product first produced is a colourless liquid, soluble in water; on further heating, this is transformed into an intermediate rubber-like product, which is insoluble in water and infusible; the final product, obtained by still further heating or by combined heat and pressure, is a hard infusible transparent mass, insoluble in acids and alkalies. The presence of free formaldehyde must be avoided during the conversion of the initial product into the intermediate and final products; that is to say, the formaldehyde should not be present in greater excess than corresponds to three molecules of formaldehyde to one molecule of urea. A solution of the initial product, or the initial product itself, may be used for impregnating paper or pasteboard.

Title: Improvements in process of producing pure aluminium hydrate, particularly from aluminium-containing raw materials rich in silica
IPC: C01F7/26
Filed: 1925-11-18
Abstract: Pure alumina is obtained from siliceous materials such as clay by first making aluminium sulphate by known methods, treating the sulphate with sodium sulphydrate to precipitate crude alumina containing ferrous sulphide and liberate sulphuretted hydrogen, dissolving the alumina in sodium sulphide solution so as to obtain alkali aluminate and a residue containing ferrous sulphide, and precipitating pure alumina from the aluminate by means of sulphuretted hydrogen, thus re-forming the alkali sulphydrate.  In the treatment of aluminium sulphate with the sulphydrate, the aluminium sulphate as a hot concentrated solution may be introduced into the sodium sulphydrate maintained in active movement in a mixer. The sulphuretted hydrogen produced in the precipitation of the crude alumina is more than is required to precipitate pure alumina from the aluminate, and the surplus is converted into sulphur dioxide which, together with that obtained by roasting the ferrous sulphide, is converted into sulphuric acid.  The sodium sulphate produced in the process is reduced to sulphide for use again.  The Specification as open to inspection under Sect. 91 (3) (a) states that potassium compounds may be used instead of the corresponding sodium compounds, and that the alkali sulphide solution may be freed from carbonate by treatment with lime.  This subject-matter does not appear in the Specification as accepted.
