Inventor: ROE JOHN PEARCE
IPC: B61B12/02
Filed: 1917-02-26
Abstract: 126,720. Roe, J. P. Feb. 26, 1917. No Patent granted (Sealing fee not paid). Travelling ropeway conveyers; rope railways.- Terminal stations for rope railways or travelling ropeway conveyers, in which the carriers are either passed on to a shunt at the terminal station or remain attached to the rope, are constructed for erection on land that has not been previously prepared by forming the parts capable, of easy detachment or erection. Fig. 1 shows the arrangement at a terminal station employing a shunt track and provided with tensioning arrangements. A supporting frame of uprights 3 and horizontals is provided with wheels b so as to move on the rails c to allow for tensioning by the rope 8, one end of which is connected to a ground anchor while the other end, after passing over pulleys 12, is connected to a winch. The frame carries a pedestal h in which a pillar f is stepped, the upper end of which forms axles for the rope drum g and its toothed driving wheel. A link p attached to the top of the pillar f is connected to the tension wheel 12. Power is transmitted to the rope drum from any desirable source x through the necessary gearing to a shaft, the upper end of which has a bearing in an arm i carried by the pillar f. The supporting frame is arranged to carry the shunt rail 1 and guide-pulleys 4 for the travelling rope A. At a terminal station where there is no tensioning, the various parts are secured directly in or on the ground instead of on a movable structure. Similarly, when no shunt rail is employed, the parts are shaped and arranged so that the carriers pass round the rope drum without disconnecting from the rope.

Title: Production of vitamin a aldehyde
IPC: C07C47/38
Filed: 1958-01-28
Abstract: The invention comprises 1-alkoxy-3 : 7-dihydroxy - 3 : 7 - dimethyl - 9 - (21 : 61 : 61-trimethylcyclohex - 11 - enyl) - nona - 1 : 8-dien-4-ynes and the corresponding 1 : 4 : 8-trienes (the alkoxy groups of which contain up to 10 carbon atoms), the preparation of the former by condensation of a di-magnesium halide of 4-hydroxy-4-methyl-6-(21 : 61 : 61-tri-methylcyclohex - 11 - enyl) - hex - 5 - en - 1 - yne with a 4-alkoxybut-3-en-2-one, the conversion of the 1 : 8-diene-4-ynes into the 1 : 4 : 8-trienes by partial hydrogenation, the conversion of the 1 : 4 : 8-trienes into Vitamin A aldehyde by subjecting them both to hydrolysis and to dehydration in the presence of an acid and, if desired, the conversion of Vitamin A aldehyde to Vitamin A by hydrogenation and the formation of retinylidene acylhydrazones by reaction of Vitamin A aldehyde with an acylhydrazine.  The condensation involving the dimagnesium halide may be conducted in a solvent such as an ether and the dihydroxy-1 : 8-dien-4-yne isolated after hydrolysis of the dimagnesium halide compound first formed. Suitable catalysts for the hydrogenation step include Raney nickel and palladium on a carrier, the activity of which may be modulated by the addition of an organic base or lead, the reaction advantageously being effected in a suitable solvent. The hydrolysis and dehydration steps are advantageously effected simultaneously in the presence of an acid such as a mineral acid, formic, acetic or oxalic acid or p-toluene sulphonic acid, which can be used together with a cation exchange material, preferably in an organic solvent and in presence of an organic salt of an alkali metal or a metallic salt such as lithium chloride and an oxidation inhibitor such as tocopherol or hydroquinone.  In a modification of this process the dihydroxytriene is treated with diketene to form the diacetoacetate which is then treated with an acid when hydrolysis accompanied by dehydration and de-acidification occurs to form Vitamin A aldehyde.  Examples illustrate all the above processes, and the 2 : 4-dinitrophenyl hydrazone of Vitamin A aldehyde is described. In an additional example the 1-methoxy-dihydroxytriene is shaken with 10% sulphuric acid in dioxan in an inert atmosphere to give a product of the probable structure <FORM:0861460/IV (b)/1> which on heating with 2 drops of concentrated hydrochloric acid in dimethylformamide gives Vitamin A aldehyde.  U.S.A. Specifications 2,676,990 and 2,676,991 are referred to.

Title: Improved production of alkali metal, including ammonium, zirconium or hafnium doublefluorides
IPC: C01G25/04
Filed: 1953-02-02
Abstract: Alkali metal including ammonium double fluorides of zirconium or halfnium are prepared by calcining a finely divided oxidic ore of the metal with a compound of calcium, strontium or barium at 2200-2400 DEG C. to form a calcium &c. oxidic compound with the metal, e.g. calcium zirconate or calcium zirconium silicate, adding sulphuric or phosphonic acid, cooling and digesting the resultant slurry in alkali metal fluoride solution at 100 DEG C. or less and crystallizing the resultant double fluoride in the presence of an alkali metal fluoride (which need not be the same as that in the double fluoride).  The compound of calcium &c., preferably limestone, is added in an amount to provided one mole thereof per mole of both the Girconia and silica which may be present. Calcium chloride (10 mole per cent of the limestone) may also be present.  According to a typical example, zirconium ore (baddeleyite) containing 77 per cent. zirconia together with iron, silica and alumina, is ground and mixed with calcium carbonate and chloride.  The mixture is calcined at 2400 DEG C. for one hour, cooled, ground and slurrie in water.  Sulphuric acid is then added in amount sufficient to provide 1 mole thereof per mole of lime and sufficient in addition to combine with all the alkali metal (to be subsequently added) which does not go into the double fluoride to be formed.  After the exothermic reaction the mass is cooled, broken up and dispersed in water at 90 DEG C.  A solution of sodium and potassium fluorides at 90 DEG C. is added slowly and digestion continued at 90-100 DEG C. for one hour with stirring. After dilution, powdered iron is added to convert any iron present to the insoluble hydrate and digestion continued for 15 minutes. The temperature being maintained, the solution is allowed to settle and the clear liquid is decanted.  The precipitate is washed with a mixture of sulphuric acid and potassium fluoride and the combined decant and wash water is evaporated and cooled to produce crystals of potassium zirconium fluoride.  Specification 682,757 is referred to.

Title: Improvements in and relating to phase and frequency modulation systems
IPC: H03C3/40
Filed: 1949-02-03
Abstract: 657,272. Phase and frequency modulation. BRITISH THOMSON-HOUSTON CO., Ltd. Feb. 3, 1949, No. 3006. Convention date, Feb. 3, 1948. [Class 40 (v)] Relates to phase. modulating circuits of the kind in which carrier from a source 1 is fed in push-pull to a pair of valves 4, 5 and in quadrature phase to a parallelfed pair 12, 13, each pair having its anodes connected in push-pull to an output circuit 16; and consists in applying modulating voltage from a source 23 in push-pull to the quadrature valves 12, 13 and a fraction of the modulating voltage in push-pull to the valves 4, 5. In this way linearity of modulation may be obtained over a greater phase swing than with known arrangements. The carrier output from the circuit 16 has two components in quadrature, one EA, Fig. 2, arising from the valves 4, 5 and the other EB from the valves 12, 13 giving a phase-angle # for their resultant a. The valves 12, 13 give linear amplitude modulation so that EB or y is proportional to the modulating voltage u. The valves 4, 5 have anode-current grid voltage characteristics 26, 27, Fig. 3, such that their resultant 28 is a cubic of the form i=au +cu<SP>3</SP>. The modulated carrier EA from these valves is dependent on the slope of this cubic and is proportional to a+ 3cu<SP>2</SP>. The phase angle # of the resultant of EA and EB is of the form tan <SP>-1</SP>y/l+ky<SP>2</SP> and in the particular case in which k is minus one-third, this approximates to y - y<SP>5</SP>/45, ignoring powers of y higher than the sixth. The deviation from linearity is expressed by the fraction (# y)/y which equals y<SP>4</SP>/45 and is of small amount.
