Patent GB-565533-A (GB)
Title: Improvements in or relating to the ring-spinning of yarns
IPC: D01H1/36
Filed: 1943-03-01
Abstract: 565,533. Ring - spinning. BRITISH CELANESE, Ltd. March 1, 1943, No. 3338. Convention date, Feb. 28, 1942. [Class 120 (ii)] A method of forming packages of yarn on flanged bobbins by ring spinning comprises traversing the yarn by means of a ring and traveller over a field of traverse having a substantially constant length that is slightly shorter than the bobbin and shifting the field of traverse to and fro along the length of the bobbin with a frequency that is lower than the frequency of traverse. The traverse bar 13, supported by posts 12, is reciprocated vertically by a lever 17 attached to a shaft 21 and counterweighted at 18, the lever 17 being connected to a lever 19 moved by a chain 54 attached to an idler pulley 52 by a projection 53. Attached to the pulley 52 is another idler pulley 51, formed with a flat at 55, to which is attached a chain 46 attached at its other end to an extension 45 of an eccentric sheave 44, the eccentric 43 of which is carried by a shaft 29 and fixed to a ratchet wheel 42 rotated step-by-step by a spring- loaded pawl 39 pivoted to an arm 32 pivoting on the shaft 29 and counterweighted at 33. A rod 34 carried by the arm 32 has adjustable collars 35, 36 which are arranged to contact an abutment plate 37 when the arm 32 and the ratchet assembly is moved upwardly and downwardly by the builder arm 27 pivoted at 28 and operated by a heart-cam 22. The arrangement is that the rings and traverse bar are raised by the counterweights 18 and lowered by the positively driven cam 22. The traverse of the bar 13 is thus of constant length, but due to the eccentric 43 the traverse is moved a short distance to and fro during the building of the package. The flat 55 and the projection 53 combine to accelerate the rate of traverse of the bar 13 as it moves towards the top of the package at B, whereas the lower portion of the package A is built at constant traverse speed so producing a tapered top to the package. The portion C is preferably about <1>/45 th of the entire length of the package, the traverse being A +B - C.

Title: Improvements in or relating to the etching of metal objects
IPC: C23F1/42
Filed: 1952-02-08
Abstract: 709,315. Etching. DOW CHEMICAL CO Feb. 8, 1952 [Feb. 12,1951], No. 3428/52. Class 100 (2) An etching bath for etching an acid-soluble metal, e.g. in making a printing plate, comprises a mixture of a petroleum sulphate having from 18 to 30 carbon atoms, a liquid petroleum fraction boiling in the range 90‹ C. - 390‹ C., and an aqueous solution containing nitric acid. Preferably the nitric acid solution contains between 5 per cent and 10 per cent of HNO, by weight, the weight of the petroleum fraction being at least 1.3 times the weight of the petroleum sulphonate, but not more than 0.15 times the weight of the aqueous nitric acid solution. The petroleum sulphonates used may be the petroleum sulphonic acids and salts thereof, e.g. naphthenic soaps or mahogany soaps. The preferred sulphonates have 24-26 carbon atoms, the sodium salts having the empirical formula CxHySO 3 Na where y = 2x - 10. Examples of petroleum fractions used are gasoline, benzine, kerosene, coal oil, and lubricating oil. Inclusion of the petroleum sulphonate and petroleum fraction increases the ratio of the depth of the etch to the amount of lateral attack on the metal underlying the parts of the plate coated with a resist. The composition may be splashed against the plate.

Title: Card transferring apparatus
IPC: G06K13/10
Filed: 1958-02-03
Abstract: 872,609. Feeding and delivering sheets. MAGNAVOX CO. Feb. 3, 1958 [Feb. 21, 1957], No. 3430/58. Class 100(1) Apparatus for transferring record cards comprises a card-transporting means, an adjacent card-holding means having a fixed surface on which cards are supported on edge, and means constantly movable along this fixed surface and engaging the cards for reducing the frictional forces between the cards and the fixed surface during the transfer of cards between the cardholding and transporting means. As described, the apparatus is for use in connection with a card sensing or reading device 76, the cards having data thereon in the form of perforations or magnetised areas, and being removed sequentially from a card holder 20 by a rotating suction drum 16, carried past the device 76, and stacked in a holder 42. The leading edge of the bottom card in the holder 20 rests on the face of the drum, this face having peripheral recesses therein which are in constant communication with a vacuum pump, but the trailing edge of the card is gripped by suction to the face of a retainer 24. When a solenoid valve 30 is closed in response to a signal, the retainer 24 is cut off from its source of suction, and the card is removed by the drum 16. The card is stripped from the drum by a stripper 46, and stacked in the holder 42. Both card holders are mounted on a table 18, and comprise parallel side bars between which cards are stacked on edge, a pusher member urging the cards towards the drum under the action of a coil spring, and a pair of constantly-driven endless belts on which the bottom edges of the cards rest. In the holder 20, the pusher 32 is urged by a coil spring 34 which gradually winds up as the stack is depleted, the wound coil constantly engaging the pusher. The endless belts 38, 40 are mounted on rollers driven by a motor, the upper runs of the belts moving towards the drum 16. In the holder 42, the pusher 50 is urged towards the drum 16 by a coil spring 52, and the upper runs of the belts 56, 58 move away from the drum 16. In both cases, the force exerted on the cards by the belts is not sufficient to overcome the actions of the coil springs on the pushers. The purpose of the moving belts is to overcome frictional drag between the cards and the table 18 and thus speed up card separation and stacking. The moving belts may be applied to the apparatus described in Specification 871,548 wherein each card holder can be adapted either to allow cards to be separated therefrom by a rotating suction drum, or to receive cards from the drum. In this case the belts are driven by reversible motors which are automatically arranged to drive the belts in a direction suited to the operational modes of the holders.

Title: Improvements in and relating to the Production of Ammonium Nitrate.
Inventor: PARTINGTON JAMES RIDDICK
IPC: C01C1/18
Filed: 1918-03-04
Abstract: 136,190. Partington, J. R., Jones, G. J., and Brownson, T. K. March 4, 1918. Ammonium nitrate is produced in the solid form by bringing together oxides of nitrogen, oxygen, water, and ammonia under such conditions that the proportion of oxygen present is in excess of that required to convert the whole of the oxides of nitrogen into nitrogen dioxide, the proportion of ammonia is insufficient to react with the whole of the oxides of nitrogen, and the proportion of water is not in excess of, and is preferably equal to, that which is sufficient to convert the whole of the ammonia added into ammonium nitrate by interaction with the oxides of nitrogen and oxygen. In the case of gases containing about 10 per cent by volume of oxides of nitrogen, produced, for example, by the oxidation of ammonia, an amount of oxygen equivalent to three or four times that theoretically required to convert the whole of the oxides of nitrogen into nitrogen dioxide may be added. The oxygen may be added in the form of oxygen gas, air, or air enriched with oxygen, and the water should be in a finely divided state, for example as vapour or spray. The process may be carried out in the apparatus shown. Oxides of nitrogen containing moisture, after passing through a cooler A where excess moisture, if present, is condensed, are passed, together with air or oxygen admitted through a valve C, into an oxidizing-chamber D; the oxidized gases, cooled if necessary, then pass to the first reaction chamber E<1>, into which a mixture of air and ammonia is admitted through a tube F<1>. Solid ammonium nitrate is deposited, and the residual gases pass into successive reaction chambers E<2>, E<3>, &c. of gradually increasing size, where they are treated with further quantities of air and ammonia. An empty chamber or tower, to act as an oxidizing- space, may be interposed between any two of the reaction chambers.
