Patent DK-85898-A (DK)
Inventor: JUHL FOENS MOGENS
IPC: F04C29/04
Filed: 1998-06-17
Abstract: A typical impeller wheel compressor has a limitation relating to the maximum delivery pressure, cf. the fact that the temperature of the output gas after an isentropic compression becomes high, even at a moderate pressure. The internal parts of an impeller compressor have to resist said temperature. 1. By returning and cooling part of the high pressure delivery mass flow, and by returning the mass flow to the expansion side of the rotor, or 2. by injecting relatively cold gas into the expansion side of the rotor, the temperature can be further lowered at the subsequent expansion. The returned or injected mass flow is mixed with a mass flow from the inlet, whereby the temperature of the mixture will be lower than the temperature of the inlet gas. Hereby, the impeller wheel compressor may reach a higher delivery pressure at the same delivery temperature. <IMAGE>

Title: Improvements in and relating to the manufacture of sulphur
IPC: C01B17/04
Filed: 1936-01-02
Abstract: Sulphur is obtained in maximum yield from gases containing sulphur dioxide and/or sulphur trioxide by reaction with such an amount of substances containing hydrogen and/or carbon in free or combined form that in the resulting gaseous mixture, after removal of free sulphur, the concentrations (in volume percentage) of carbon oxysulphide, hydrogen sulphide and carbon disulphide, if present, satisfy the relation SO2/(COS+H2S+CS2)=1 or substantially 1.  The gases may be treated with carbonaceous substances, or bodies containing carbon combined with oxygen and/or sulphur, e.g. carbon monoxide, carbon dioxide, carbon disulphide or carbon oxysulphide, or with hydrocarbons or mixtures containing both carbon and hydrogen, or bodies containing carbon and hydrogen combined with oxygen or sulphur, e.g. phenolic oils, hydrogen sulphide or water.  According to an example, the gas to be treated contains 7 per cent sulphur dioxide, 10 per cent oxygen and 83 per cent nitrogen.  This is reacted at 800 DEG  C. with carbon so that the C/S ratio is 2,425, i.e. so that 29,1 gms. of carbon are gasefied for every 32 gm. of sulphur.  The residual gases contain 0,3 per cent sulphur dioxide, 0,3 per cent carbon oxysulphide and 0,001 per cent of carbon disulphide and the sulphur yield is 92 per cent.  The carbon may be injected in pulverized form into the gases, or the gases may be passed at temperatures of 800--1400 DEG  C., over an excess of carbon, the speed being adjusted in accordance with the amount of gasefied carbon required, or a portion of the gases may be passed over carbon to give an excess of gasefied carbon, the remainder of the gases then being added in the required amount.  A catalyst may be used if desired.

Abstract: 938,407. Protective arrangements. PHILIPS ELECTRICAL INDUSTRIES Ltd. Jan. 3, 1962 [Jan. 6, 1961], No. 260/62. Class 38 (5). [Also in Groups XXXV and XL (b)] In a protective arrangement for a rectifier comprising a plurality of semi-conductor rectifying elements D 1 , a glow-discharge lamp L in series with a resistor R 1  is connected in parallel with each element D 1 , and a photo-resistance element W is arranged in proximity to each lamp L, the elements W being connected in series with a relay circuit adapted to operate alarm and/or safety means. In the arrangement shown, constant resistances R 2  are connected in parallel with the photo-resistance elements W which are connected in series with resistors R 3  ... R 5  across a half-wave rectified A.C. supply. Under normal conditions the lamps L are lit by the inverse voltages across the elements D 1  and the resistances of the elements W are low so that the potentials across the resistors R 4 , R 5  are sufficient to ignite two relay tubes B 1 , B 2  and relays S 1 , S 2  are energized. Should one element D 1  fail, the associated glowdischarge lamp L is extinguished causing the associated photo-resistance element to increase its resistance and reduce the potential across the resistor R 5 . Relay tube B 1  no longer ignites and relay S 1  releases to cause an alarm to be given. Should two elements D 1  fail, then the reduction in potential across the resistors R 4 , R 5  is such that the tube B 2  no longer ignites and relay S 2  releases and causes the interruption of the supply circuit. A fuse F may be provided in each branch of series-connected rectifier elements D 1 . Fig. 2 shows how the lamps L and photo-resistance elements W are mounted in recesses in an opaque block 1 of synthetic resin with a hood 2 so that the lamps L are visible but the elements W are shielded from external light.

Title: Process for the preparation of precooked rice
IPC: A23L7/196
Filed: 1963-01-03
Abstract: 1,010,854. Pre-cooked rice products. RIVER BRAND RICE MILLS Inc. Jan. 3, 1963 [Jan. 3, 1962; June 13, 1962], No. 390/63. Heading A2Q. In preparing a pre-cooked rice product, grains of rice, e.g. white or brown raw rice or parboiled rice, are heated to a relatively high temperature, e.g. between 120‹ and 220‹F. for raw rice, or between 200‹ and 225‹F. for parboiled rice, then cooled to a lower temperature, e.g. between 60‹ and 100‹F., and heated again to a relatively high temperature, e.g. between 120‹ and 230‹F. for raw rice, or between 200‹ and 225‹F. for parboiled rice, which heating- cooling-heating cycle may be repeated, to produce rifts, crevices, cracks and chinks in the grains thus making them highly permeable and absorptive to water and/or water vapour. The grains may be heated and cooled by hot and cold air and may be in the form of a bed, between 1 and 3 inches thick, on one or more, e.g. three, travelling conveyers. The bed may be quiescent or fluidized by the hot and cold air. The grains are then cooked, e.g. at atmospheric pressure or at a pressure not exceeding this by more than 5 p.s.i., in hot water, e.g. at a temperature of 195‹ to 210‹F., followed, if desired, by cooking in steam, until they are substantially completely gelatinized. The water-cooked grains may be cooled, i.e. quenched, in cold water or air before they are finally cooked in steam. The cooking water may be distilled water or water having a pH between 5 and 7. The cooked grains are then dried, continuously or in batches, by a hot gas, such as air or nitrogen, until they have a stable moisture content, e.g. between 6 and 11 per cent., by weight. The resulting dried, pre-cooked rice grains may be enriched with a vitamin and packed. The cooked rice grains may be dried by a hot gas in two stages, namely at a temperature between 250‹ and 350‹F. for raw rice, or between 300‹ and 360‹F. for parboiled rice, and then at a temperature between 210‹ and 280‹F. The hot gas may be passed upwardly and downwardly through a bed of cooked grains. Additives, such as flavourings, seasonings and emulsifiers, may be sprayed on to the grains between the drying stages. The cooked rice grains may be cooled and washed in cold water, e.g. having a pH between 7 and 8, before they are dried. Brown rice grains, after having been heated, cooled and re-heated in the above-mentioned manner, may be soaked in tepid water before being cooked.
