[Also in Group XIII] In a steam boiler comprising essentially a steam-and-water drum 36, steam-generating tubes 39, and downcomers 41, small solid particles and other impurities in the steam are removed by the passage of the steam through a series of grid trays 45, each formed for example of spaced rectangular bars, in opposition to a flow of relatively pure water such as condensate from the plant using the steam, normal feedwater or, as shown, condensate resulting from contact of the flowing steam with horizontal tubes 47 leading from a feedwater inlet header 48. The trays are mounted within a peripherally closed column having side walls 42 extending substantially the length of the drum, and in one specific example they are spaced 4 inches apart and are each constituted by bars which are 1 inch wide and “ inch thick and are spaced 1“ inch centre to centre to provide slots “ inch wide between adjacent bars. Chevron-shaped fins constituting a steam-and-water separator 46 may be mounted on the tubes 47, and baffles 50 are preferably disposed immediately below the steam outlets 38 of the drum. The steam-generating tubes 39 discharge against a baffle 40 which may depend below the level 37 of water in the drum and be provided with outlets leading to associated cyclone or other steam separators.

Title: Refrigeration apparatus including a fluid distribution control device
IPC: F16K31/68
Filed: 1965-08-02
Abstract: 1,085,439. Refrigerating. W. E. GIFFORD. Aug. 2, 1965, No. 33012/65. Heading F4H. [Also in Division F2] Refrigeration apparatus comprises a rotary disc valve member 16 driven by a motor 26 and controlling communication between a chamber 20 and chambers 30, 32, 34 defined by a piston 8. The chamber 20 is connected to a source of compressed fluid, e.g. helium or air. During the first 45 degrees of rotation of the disc, fluid flows from chamber 20 to chamber 30 via arcuate passages (38, 40) in the disc (Fig. 6, not shown) and passage 42, thereby depressing the piston. During the next 45 degrees of rotation gas passes from chamber 20 to chambers 32, 34 via the same arcuate passages and passages 44, 44a, 55, the latter passage containing a thermal regenerator 4. During the third 45 degrees of rotation gas still passes to passage 44, but chamber 30 is exhausted via arcuate passages (46, 48) in the disc, radial passage 54 in the disc and radial passage (56) (Fig. 3, not shown) in the seat member 10. The piston therefore rises and fluid in chamber 32 is transferred to chamber 34 via passages 44a, 55. During the fourth 45 degrees of rotation chamber 34 is exhausted via passages 55, 44, 46, 48, 54 and 56, thereby cooling the heat exchanger 57 due to fluid expansion. The cycle is repeated in the subsequent 180 degrees of rotation.

Abstract: 362,116. Electromagnetic interrupters. CHANCE BROS. & CO., Ltd. and SPAINK, J. H. ABBINK-, Lighthouse Works, West Smethwick, Staffordshire. Nov. 4, 1930, No. 33122. [Class 38 (v).] Contacts.-Voltage regulattors and other apparatus of the kind comprising a coil mounted so as to oscillate in a magnetic field, the coil carrying a lever fitted at each end with a contact co-operating with a corresponding fixed contact have the fixed and movable contacts mounted on iron or steel supports arranged to be traversed transversely by a magnetic field such as a stray field from the main relay magnet, repulsive forces thus being produced between the contacts which are thereby prevented from sticking together. As shown in the Figure, the operating coil d is pivotally mounted in the field of the permanent magnet e and is secured to a non-magnetic lever a fitted with contacts b of tungsten or other suitable material, the tungsten contacts being mounted on iron or steel supports h. Similarly fixed contacts c arranged below the contacts b are mounted on magnetic screws g passing through non-magnetic brackets secured to the magnet polepieces. The magnet is arranged to have a relatively large stray field which traverses the iron or steel contact-carrying parts transversely so setting up repulsion between these members. Thus the force required to separate the contacts is reduced and risk of the contacts adhering is eliminated.

Title: Improvements in or relating to the manufacture of primary alcohols of the vitamin a-series
Filed: 1953-12-03
Abstract: Alcohols of the Vitamin A series of the general formula <FORM:0751753/IV(a)/1> where n=1 or 2, are prepared from the corresponding acid halides by known methods for converting acid halides into the corresponding alcohols.  The acid halide may if desired be converted into the corresponding acid or an ester thereof which is reduced to the alcohol, or the acid halide may be reduced directly.  Suitably the reduction may be effected by means of a metal hydride containing two metal atoms such as lithium aluminium hydride, sodium boron hydride or magnesium aluminium hydride.  The reaction is suitably carried out at a temperature below 5 DEG  C. Examples describe the preparation of the corresponding alcohols by reduction with lithium aluminium hydride of (1) b -ionylidene acetic acid chloride; (2) Vitamin A acid chloride; (3) b -ionylidene acetic acid ethyl ester (obtained by treating b -ionylidene acetyl chloride with ethanol in the presence of pyridine); (4) Vitamin A acid ethyl ester (obtained by treating Vitamin A acid chloride with ethanol in the presence of pyridine); and (5) b -ionylidene acetic acid (obtained by hydrolysis of the acid chloride).  b -Ionylidene acetyl chloride is made by treating b -ionone with bromoacetic acid ethyl ester, splitting water off from the resulting b -ionone acetic acid ethyl ester by treatment with p-toluene sulphonic acid to give a product containing the ethyl esters of b -ionylidene acetic acid and b -iso-ionylidene acetic acid, hydrolysing the esters to the free acids and treating with phosphorus trichloride to give the required product.  Vitamin A acid chloride is made by converting the C18 ketone into the iso-C20 acid and treating this with phosphorus trichloride by the same sequence of reactions used for the preparation of b -ionylidene acetyl chloride.  Specification 744,804 is referred to.

Abstract: 481,770. Insulation. COMPAGNIE GENERALE D'ELECTRO - CERAMIQUE. Dec. 8, 1936, No. 33729. Convention date, Dec. 31, 1935. [Class 36] To prevent electric discharges in open air high-tension installations, small quantities of gases or vapours are continuously evolved in the vicinity of the high-tension conductors to form a protective sheath around the conductors which increases the disruptive voltage of the surrounding atmosphere. The vapours may be evolved from vaporizers arranged near the points of possible discharge, or the conductors may be covered by a film of liquid which evolves the protective vapour, the liquid preferably impregnating a layer of absorbent material covering the conductors. The vapours of carbon tetrachloride, non - inflammable halogen compounds, or conducting liquids may be employed for the protective sheath.

Data processing equipment comprising first and second data processors for performing operations of a first and second category, respectively, includes control means whereby, when one of the data processors is out of service, the other processor performs both categories of operations. In a system for checking the availability of, and booking seats on aircraft, the equipment at the central station is duplicated. One portion (upper part of the figure-not shown) is used for bookings on local flights while the other (lower part) is used for international flights. A pair of inter-processor transfer equipments TN, TA are provided which transfer the information from either portion to the other so that both portions contain all the information. This allows either one processor to be used for all flights, both local and international, in the event of a breakdown of either one processor. Each portion includes a magnetic drum store DSD, DSI, and a scanner DC, DI which scans the agents keysets for any requesting information. Information relating to a desired flight is fed to a control circuit ND, NI, which is of the type described in Specification 910,471. The control circuit locates through address tracks on the drum the desired information and returns it to the agent's set. If a firm booking is made the name of the passenger, his address and his intended flight are fed in on lines ID, DI to a control circuit AD, AI which records this information in random access tape stores ATS, ATI. An updating equipment TD, TI makes corresponding amendments to drum store DSD, DSI as required.
