Title: Knitting machine
Inventor: TENCONI RICCARDO
IPC: D04B9/18
Filed: 1961-09-15
Abstract: 937,965. Knitting machines. M. S. MOSETTA. Sept. 15, 1961, No. 33106/61. Class 74 (2). A knitting machine for forming reinforced parts on socks and stockings comprises rocking jacks 15 which may be moved from an inoperative position to an operative position by cams 25, 26 which are rotatable with the needle cylinder 2. When in the operative position, Fig. 3, jacks 15 can be engaged by a cam 24 to lift the needle 6 so that it grips a supplementary thread fed through guide 14 as well as the normal thread fed through guide 13. The position of cams 25, 26 and hence the number of jacks 15 in operative position is controlled by a tubular member 30, slidably mounted within cylinder 2 and rotatable therewith. Member 30 has contoured grooves 32, 33 in which rods 34 on cams 25, 26 engage. Axial movement of member 30 thus causes angular movement of rods 34 to rotate cams 25, 26. The axial position of member 30 is controlled by means of a pivoted member 36 resting on an eccentric 38 which is moved in accordance with protuberances of cams 55, 56 by rods 42, 43 acting on toothed wheels 40, 41. An alternative form of jack is shown in Fig. 9 and the grooves on member 30 are correspondingly adjusted. A multifeed may be used.

Title: Improvements in or relating to electric discharge lamps
Inventor: RIGDEN SYDNEY ALFRED RICHARD
IPC: H01J61/35
Filed: 1960-09-23
Abstract: The outer jacket of an alkali metal vapour-rare gas discharge lamp has at least part of its inner surface coated with a multi-layer heat reflecting film of high light transmissivity consisting of or including a layer of metal oxide directly on the glass surface of the jacket and a layer of gold on the layer of metal oxide.  Metal oxides referred to are those of bismuth, cadmium, lead, tellurium and antimony. The metal oxide layer can have a thickness of at least 80<\>rA and the gold layer a thickness of between 50<\>rA and 150<\>rA, e.g. 100<\>rA. There can be a further layer of metal oxide on the gold layer and each of the metal oxide layers can be about 130<\>rA thick.  A final layer can be applied consisting of a material, e.g. magnesium fluoride, which reduces the amount of light from the discharge which is reflected by the film.  The layers can be formed by a sputtering process and apparatus such as described in Specification 915,568. When the multilayer film consists of a layer of gold sandwiched between two layers of bismuth oxide the sputtering apparatus preferably employs two electrodes, the first coated with a layer of gold and the second coated with a layer of bismuth, the process incorporating the steps of producing an electric discharge between the electrodes with the second electrode acting as the cathode, whilst the jacket is rotated about its axis and contains oxygen at low pressure to cause a layer of bismuth oxide to be formed on the inner surface of the jacket, replacing the oxygen by argon at low pressure, and reversing the direction of the discharge so that the first electrode acts as the cathode and a layer of gold is formed on the bismuth oxide layer, and replacing the argon by oxygen at low pressure and reversing the direction of the discharge to cause a layer of bismuth oxide to be formed on the gold layer.  The duration of the different discharges is adjusted to form layers of the required thicknesses.  A mask can be used when parts of the jacket are to be left uncoated.

Patent GB-397161-A (GB)
Title: Improvements in or relating to the oxidation of olefines
IPC: C07C51/25
Filed: 1931-12-03
Abstract: Oxygen-containing organic compounds other than glycols or alcohols, such as olefine oxides, aldehydes, ketones and acids are produced by the oxidation under increased pressure of olefines containing not more than five carbon atoms with oxygen or air in presence of water or steam at least sufficient to saturate the gases at room temperature and pressure but insufficient to produce substantial quantities of alcoholic products such as glycols, the production of which is covered by Specification 387,372.  The gases may be passed through hot liquids containing oxygen carriers, preferably liquids of an acid nature or containing oxygen carriers of an acid nature such as chromic acid, manganese acetate, or chromium acetate which may be dissolved in water or acetic acid.  Unless the solution comprises water, steam is added to the gases.  Preferably the gas mixture is treated at high temperatures such as 200-600 DEG  C. in presence or absence of catalysts such as heavy metals or their compounds, for instance, silver or copper, or silver, copper, chromium, cobalt, or iron oxides or vanadium pentoxide, which may be associated with promoters such as alkali or alkaline earth compounds, and carriers such as pumice, kieselguhr, carborundum or silica gel may be employed.  The pressure may be up to 10 atmospheres, preferably 2-5 atmospheres.  Diluent gases such as nitrogen and carbon dioxide may be used.  When ethylene oxide is desired, its further change may be minimized by using moderate temperatures, a considerable quantity of diluent, high speed of the gas, and avoidance of acid catalysts in the reaction zone, ammonia or other volatile base being added to the gases if desired; inert packing may be used instead of catalysts, or neither filling materials nor catalysts may be employed.  To produce acetaldehyde hydration catalysts such as phosphoric acids and zinc chloride may be used, or the products of reaction may be passed over these catalysts at 300-400 DEG  C.  The formation of acetic acid is favoured by the use of an excess of oxygen, relatively high temperatures and oxidation catalysts such as silver, copper, or their oxides.  Propylene may be oxidized to acetone, and butylenes and amylenes to the corresponding ketones.
