Title: Production of high molecular weight acetaldehyde formaldehyde polymers
IPC: C08G2/20
Filed: 1960-11-23
Abstract: High molecular weight crystallisible linear acetaldehyde polymers having a polyacetatic structure and including copolymers of acetaldehyde and formaldehyde are prepared at -50 to -100 DEG C. using as catalyst an organo-metallic compound or hydride of a metal of Group Ia, II or III of the Mendel<\>aeeff Periodic Table. Particularly useful catalysts are aryls, alkyls and hydrides of lithium, sodium and potassium and alkyls, aryls, hydrides, alkyl hydrides, alkyl-halides and alkoxy-alkyls of beryllium, magnesium, calcium, zinc, cadmium, aluminium and boron as well as their complexes with oxygen-containing organic bases such as ethers. Polymerization may take place in the presence or absence of a diluent e.g. aliphatic or aromatic hydrocarbons, halogen derivatives of these and ethers.

Title: Improvements in or relating to full-fashioned knitting,knitting machines and knittedgarment blanks and articles
IPC: D04B/
Filed: 1962-07-21
Abstract: Men's pants are fashioned on a straight-bar machine to produce a front pouch, Fig. 6, not shown. This is achieved by causing two outer groups a, b and b1, a1 of needles to hold their loops without knitting whilst continuing to knit on the central group b, b1 of needles. The number of needles knitting in the central groups is gradually increased and then decreased as diagrammatically illustrated in Fig. 1. Subsequently all of the needles resume knitting. The widening and narrowing effect of the central group of needles can be effected a second time in succession before recommencing knitting. The machine has the normal presser mechanism modified during the fashioning of the pouch so that the needles are not caused to press and thereby fail to knit. The central needles are caused to press and knit by the action of auxiliary presser mechanism comprising two presser plates 101,102, Fig. 4 not shown, which bear on the backs of the needles and press them so that their heads engage the usual presser edge. The plates 101,102 are capable of being moved in an overlapping disposition such that the number of needles affected can be increased and decreased.

Title: Cyclic process for the recovery of bromine from mixtures of hydrobromic and sulfuricacids
IPC: C01B7/09
Filed: 1964-01-08
Abstract: <PICT:1021613/C1/1> Bromine is prepared from hydrobromic acid or mixtures containing it by oxidation with nitric acid or nitrogen oxides, such as those obtained by the combustion of ammonia, in a solution of acidity at least 5N. The hydrobromic acid-containing mixture may be that obtained in the recovery of bromine from sea water by treatment of brominated air with sulphur dioxide and spray water and consists of a mixture of HBr and H2SO4, referred to in the Specification as "bromosulphuric acid." Bromo-sulphuric acid containing 50-250 g. HBr per litre is fed via line 1 (see drawing) to packed column 2 and thence to reaction zone 3 supplied with nitric acid, e.g. 50-70% concentration, through line 4 and make-up mineral acid to achieve the required acidity through line 5. The reaction solution is maintained, preferably under atmospheric pressure, at between room temperature and the boiling point of bromine by inserting cooling means between reactor 3 and column 2, or the bromosulphuric acid may be pre-cooled to below room temperature. When the bromosulphuric acid concentration is 70-100 g. per litre, or the make-up acid is sulphuric acid of low concentration, or is hydrochloric acid, heat is required to promote the reaction. Sulphuric acid in the reaction solution is preferably 20 to 36% by weight. Bromine formed flows through line 7 to packed column 8 maintained at near room temperature and air or oxygen entering via 9 carries away entrained nitrosyl bromide via pipe 10 to the bottom of column 2. The bulk of the NoBr produced in reactor 3, plus that arriving via pipe 10, plus air or oxygen introduced via line 6, ascends column 2 and, in contact with descending bromosulphuric acid, is converted to nitric and hydrobromic acids which return to the reactor 3. Residual acid from reactor 3 passes via line 12 to packed column 13 into which steam and optionally air or other inert gas is passed via line 14. Dissolved bromine is thereby returned to reactor 3 via line 15. Bromine-free residual acid leaves via line 16, gases via 17 and bromine via line 11.

Patent ES-370655-A1 (ES)
Title: Color temperature correction controlled by the color killer and color oscillator
IPC: H04N9/70
Filed: 1969-08-20
Abstract: In a colour television receiver for low-colourtemperature colour and high-colour-temperature monochrome reception a colour-temperatureswitching circuit comprises a transistor 50 across a red-control variable resistor 48. The transistor is forward biased during colour reception by a rectified signal, from a colour killer circuit 9 via transformer 53 and rectifier 63, charging capacitor 65, and provides a lowresistance shunt across the variable resistor 48, thus increasing the red drive to the kinescope 48 and lowering the colour temperature. During monochrome reception, diode 59 loads the primary of transformer 53 greatly diminishing the signal in the secondary so that capacitor 65 is not charged sufficiently to forward bias the transistor 50 which thus exhibits a high impedance across the variable resistor 48 decreasing the red drive to the kinescope 18 and giving a high colour temperature. The controlling signal can alternatively be derived from a separate signal source or the horizontal circuitry instead of from the colour killer circuit. In a second embodiment the colour temperature switching circuit reduces the magnitude of the green and blue drives during colour reception, thereby effectively increasing the red drive, by connecting the transistor 50 across a variable resistor between the red control variable resistor and the common junction between the green and blue control variable resistors, Fig. 2 (not shown).

Title: Method of making self-locking internally threaded articles
IPC: B05D3/02
Filed: 1973-12-13
Abstract: Method of making a self-locking internally threaded article such as a nut including a locking body or patch of normally hard, tough, resilient thermoplastic resin adhered to the threaded surface. The article is mounted on a support with the openings at the ends substantially free. A heater raises the temperature of the threaded portion to above the softening point of the resin and a powder jet and guide device directs a stream of fine particles of the resin entrained in a gaseous jet into one of the openings toward a selected area of the threaded surface. Suction is applied adjacent the other opening of the article to draw in air around the guide and through the threaded hole in the article. Resin particles contacing the threaded surface are caught by softening them and causing them to adhere to the threaded surface by heat from the threaded surface to build up a deposit of resin which is fused by heat from the surface to form a continuous plastic body and then hardened by cooling.
