Patent GB-647210-A (GB)
Title: 4-substituted ar-tetrahydro-ª‰-naphthoxazolones
IPC: C07D263/60
Filed: 1947-08-18
Abstract: Ar - tetrahydro - b  - naphthoxazolones of the formula <FORM:0647210/IV (b)/1> where y represents a nitro, amino, hydroxy, cyano or thiocyano group or a chlorine or bromine atom, are prepared by nitrating the parent compound (where y is hydrogen) in glacial acetic acid, reducing to the amino compound (e.g. with hydrogen and a platinum catalyst), converting this to the diazonium salt and substituting the diazonium group by a hydroxy, cyaono or thiocyano group or by a halogen atom.  The substitution may be effected as follows: (1) heating the diazonium salt with dilute sulphuric acid gives the hydroxy compound; (2) heating the diazonium chloride with cuprous chloride and hydrochloric acid yields the chloro compound; (3) the bromo compound is similarly obtained from the diazonium bromide or sulphate with cuprous bromide and hydrobromic acid; (4) the diazonium halide forms the cyano compound with potassium cuprous cyanide and the thiocyano derivative with a mixture of potassium and cuprous thiocyanates.  Examples are given of the preparation of the nitro, amino and chloro compounds.  The products may be hydrolysed to 4-substituted-1-amino-ar-tetrahydro-b -naphthols as described in Specification 647,209.  The Specification as open to inspection under Sect. 91 states that low-temperature sulphonation of ar-tetrahydro-b -naphthoxazolone with fuming sulphuric acid yields the 4-sulphonic acid.  The 4-fluoro-derivative may be obtained by thermal decomposition of the 4-diazonium borofluoride and the 4-iodo-derivative from the 4-diazonium chloride with iodine and potassium iodide.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to the preservation of vegetable products
IPC: B65D81/24
Filed: 1949-09-06
Abstract: 691,682. Preserving vegetable products. OESTERLE, R. Aug. 11, 1950 [Sept. 6, 1949], No. 23106/49. Class 49. In storing vegetable products such as fruits, roots and tubers, flowers, seeds and grains in a gas-tight container, the air in the container is substituted with a gas which has no reaction upon the products stored and does not affect their respiration, e.g. nitrogen, to the required oxygen content, preferably the moisture is also removed, at intervals, and the oxygen is replaced at intervals. In Figs. 4 and 5 is shown a thermally-insulated container 1<SP>1</SP> having an apertured pipe 4' in a the carbon dioxide produced is removed, and trough at the bottom and upper apertured pipes 8<SP>1</SP>. The pipe 4' is connected through an exhauster 13, a vessel 15 of moisture-absorbing agent, and a vessel 17 of carbon dioxide-absorbing agent to the pipes 8<SP>1</SP>. The pipes 8' are also connected, by a pipe 19, with valves 21 and 22 of cylinders 23 and 24 of nitrogen and oxygen respectively. After charging the container with vegetable products, the oxygen content of the atmosphere within is decreased by opening the valve 21 of the nitrogen cylinder and opening a container outlet valve 5', and, when the desired diminished oxygen content has been attained, the valves 21 and 5<SP>1</SP> are closed. Thereafter, a hygrometer 26 functions in dependence upon the moisture content desired in the container to drive or halt the exhauster 13, gas exhausted from the container being freed from moisture and carbon dioxide in the vessels 15 and 17 and re-entering the container by the pipes 8<SP>1</SP>. Sufficient fall of pressure within the container, by reason of oxygen consumption by the vegetable products, is detected by a gauge 25, which, by means of described electrically-operated devices, causes opening of the valve 22 to admit oxygen to the container, and, upon restoration of the pressure, closing of the valve 22.

Title: Improvements in or relating to switchfuses
IPC: H02B1/40
Filed: 1950-09-22
Abstract: 674,602. Switchboards; switch cases. CANTIE SWITCHES, Ltd., and MASON, E. Sept. 22, 1950. No. 23234/50. Class 38 (v). A switch-fuse has its switch mechanism and its fuse assembly in separate casings, the casings having co-operating openings at each end so that the fuse casing may be disposed either above or below the switch casing and there is provision for the passage of conductors from one casing to the other. This enables the use of standardised casings in an installation where switchfuses are located both above and below busbar chambers and it is necessary that the switches should be adjacent the busbars. The casing 12, Fig. 3, enclosing the switch mechanism 19 has openings 26, 27 for cooperation with the openings 29, 28 of the casing 13 enclosing the fuse assembly 18. As shown, the opening 26 is adjacent the opening 29 and a plate 30 with bushed connections 31 is interposed between the casings, the connections 31 projecting into the openings. Identical connection chambers 14, 15 may be provided and these chambers may have sealing boxes 16, 17 bolted to them, or alternatively one of the chambers, i.e. that adjacent the switch, may be directly bolted to a busbar chamber, Fig. 1 (not shown), Interlocks may be provided so that neither the covers 24, 25, Fig. 4, may be opened when the switch is "on" and the switch cannot be closed while either or both of the covers are open. The switch operating shaft 22 has a member 40 which when the switch is closed, abuts a hook member 36 which is pivoted on a shaft 38 and engages in a locking bracket 44 on the cover 24. The member 40 also abuts a lever 41 which is separately pivoted on the shaft 38 and connected by a rod 42 to a hook member 37 engaging the bracket 44 of the cover 25. When the switch is opened (as shown), the opening or removal of the covers 24, 25 causes the hook members 36, 37 to pivot, so that the hook member 36 and lever 41 are moved to interlock with the member 40 to prevent operation of the switch. If the fuse casing is situated below the switch casing, the position of the rod 42 is reversed so that it extends downwardly into the fuse casing. The plate 30 may have additional bushed connections 31 to provide for a neutral connection and a neutral connecting link, Figs. 5 and 7 (not shown).
