Abstract: 849,631. Swash-plate pumps. DOWTY HYDRAULIC UNITS Ltd., and UNIPAT A. G. March 4, 1958 [March 4, 1957], No. 7131/57. Class 102(1). [Also in Group XXIX] A swash-plate pump comprises a rotating cylinder block 10 having a preferably even number of cylinders 11, and a valve body 15 having inlet and outlet ports 17, 18. Between the valve body and cylinder block is a bearing 51 in the form of a cage member having plurality of radial slots each of which houses two cylindrical rollers which are relatively rotatable, the bearing provides and maintains a low leakage working clearance between the valve body 15 and the cylinder block 10. A cylindrical member 19 secured at one end to a plug 21, bearing on the valve body, and having a flange head 25 at the other end is provided with an axial passage 27 in communication at one end with ports 17 and 18 through non-return valves 28, 29 and at the other end communicates with cylinder 23 in the cylinder block. A spring 34 in the cylinder 23 provides an initial loading to urge the valve body 15 and cylinder body 10 together and depending upon which port 17 or 18 is the high pressure port, liquid is fed past the appropriate non-return valve 28, or 29 to the cylinder 23 and acts between the flange head 25 and an annular face 20 to urge the cylinder block and valve body together during operation of the pump.

Title: Process for the manufacture of ethers from alcohols
Filed: 1930-03-05
Abstract: Ethers, such as dibutyl ether or diisopropyl ether may be employed as diluting agents for solutions of lacquers and varnishes.  Dibutyl ether may also be employed as an extraction agent for oils and fats.ALSO:Ethers are manufactured by treating aliphatic alcohols containing at least two carbon atoms in the molecule under pressure at a temperature of 200-300 DEG  C. in the presence of ferrous chloride, copper sulphate, stannous chloride, manganese chloride, aluminium chloride, chrome alum, potash alum, or chromium sulphate. The products may be employed as diluting agents for solutions of lacquers and varnishes, whilst dibutyl ether may be used as an extraction agent for oils and fats. Examples describe the manufacture of dibutyl ether from butyl alcohol employing each of the catalysts mentioned above, and of di-isopropyl ether from isopropyl alcohol employing the first two catalysts.
Patent GB-349655-A (GB)
Title: An improved process for the production of motor driving spirits
IPC: C10G45/34
Filed: 1930-03-06
Abstract: Relates to the production of motor spirit by the catalytic hydrogenation under pressure of crude benzines obtained in the distillation of coal or brown coal, or crude benzenes from high temperature coking.  The catalyst used is active carbon alone, and the hydrogenation is effected at 20 atmospheres or above, e.g. 100 or 200 atmospheres, and at 300-400 DEG  C., the conditions being such that no cracking takes place.  In examples, (1) crude benzine from low temperature coking of long-flaming gas-coal, b.p. 87-192 DEG  C. (90 per cent) is heated with one-fifth its weight of active carbon for 3 hours at 345-350 DEG  C. in hydrogen at 110 atmospheres, the pressure rising to 250 and falling again to 228 atmospheres; the cooled products, steam-blown, are free from unsaturated hydrocarbons, and boil from 89-197 DEG  C. (90 per cent); (2) crude benzine from lignite generator tar, freed from phenols and bases and boiling about 140-230 DEG  C. is heated with active carbon for 2\ba1/2\be hours at 340-350 DEG  C. in hydrogen at an initial pressure of 110 atmospheres at normal temperature: the product boiled from 123-230 DEG  C. (90 per cent); (3) crude solvent naphtha from coke oven tar, freed from phenols and bases and boiling at 181-196,5 DEG  C. (90 per cent) is heated with one-third its weight of active carbon for 2\ba1/2\be hours at 345-350 DEG  C. in hydrogen at an initial normal pressure of 110 atmospheres.  After cooling, the pressure is 95 atmospheres and is raised again to 110 atmospheres and the heating repeated; the product is steam-distilled yielding a benzine boiling from 165-220 DEG  C. (85 per cent) and 10 per cent of a yellowish resin. Specifications 205,868, [Class 91, Oils &c.], and 247,587, [Class 32, Distilling &c.], are referred to.  Reference has been directed by the Comptroller to Specifications 296,429, 300,900 and 327,463, [all in Class 91, Oils &c.].

Title: Improvements in or relating to photographic cameras and auxiliary apparatus therefor
Inventor: LESLIE NORMAN ALBERT
IPC: G03B27/465
Filed: 1957-03-06
Abstract: 856,631. Photographic cameras. INSTITUTE OF OPHTHALMOLOGY. June 6, 1958 [March 6, 1957], No. 7473/57. Class 98(1) In a micro-reproduction camera, a sheet of cut film is carried in a cassette which is periodically movable step-wise on a carrier slide by means of a spring-loaded ratchet arm and the carrier slide is stepped in a direction at right angles to the step-wise movement after each exposure. As shown, the operation of an electro-magnetic shutter release (Fig. 3, not shown) also instantaneously operates a solenoid 72 after a delay to allow the shutter to close. Pawl 69, which normally holds carrier slide 51 against the spring tension in wires 59, 60, thereby allows the slide to move through one tooth space of rack 68 to position an unexposed portion of the film carried in the cassette over exposure aperture 57. When carrier slide 57 has been moved to complete a row of exposures, switch 74 is operated by pin 73 to break the circuit of solenoid 72 and the electromagnetically operated shutter and to light a warning lamp 26. The carrier slide is returned by pulling cord 25 and, as the return motion is completed, ratchet arm 75 engages a pin on the cassette and moves it one step in a direction at right angles to the direction of travel of the carrier slide so as to align the next section of unexposed film with slot 56. As the cassette is moved to expose the last section of film, it frees pawl 78 and allows it to assume an operative position so that, should cord 25 be pulled, the pawl will contact switch 79 and thus sound a warning buzzer. The documents to be photographed are resiliently pressed against the underside of a transparent plate (Fig. 1, not shown) having concentric rectangles numbered to indicate the field of the camera at heights similarly denoted on the camera support.

Abstract: 1467083 Purifying coke oven gas H HÍLTER 25 Feb 1975 [13 March 1974 31 Aug 1974 17 Sept 1974 13 Feb 1975] 7743/75 Heading C5E [Also in Division C1] A process for purifying detarred and cooled coke oven gas comprises removing NH 3  therefrom with a water wash optionally containing H 2 SO 4 , and removing H 2 S by washing with a solution containing Na 2 CO 3  or K 2 CO 3 , the H 2 S being removed from the wash liquid with CO 2  and the wash liquid recycled, wherein NaOH or KOH is introduced into the wash liquid to replenish it before it is recycled and a corresponding amount of wash liquid is removed. In a preferred embodiment, Fig. 1, the detarred and cooled coke oven gas 1 is washed at 2 by water/ H 2 SO 4  mixture. The effluent 4 of the wash is led to an ammonium sulphate recovery plant 5. The NH 3 -free gas 6 is washed at 7 with the recycled wash liquid of circulation 8 which contains NaOH, Na 2 CO 3 , Na 2 S, NaHS (or corresponding K compounds) to provide pure gas 13. Part 11 of the effluent is passed to the ammonium sulphate recovery plant 5 and mixed with effluent 4 of the ammonia wash to provide (NH 4 ) 2 SO 4  at 15 and waste 16 containing aqueous H 2 S. An amount of KOH or NaOH solution 12 corresponding to the part 11 of the wash liquid removed replenishes the alkaline wash liquid upstream of the H 2 S removal wash. Effluent from the H 2 S removal largely passes to be treated by CO 2  10 at wash station 9 producing waste 14 containing H 2 S. The waste 16 and waste 14 may be combined to form inputs to plants producing H 2 SO 4  or S. The NH 3  and H 2 S washings may be carried out simultaneously or reversed in order.

Abstract: 195,386. Hartmann, C. W. March 21, 1922, [Convention date]. Electricity, discharging from paper.-Electricity is discharged from a paper web in a paper bag-making machine by moistening the paper by directing against it particles of water carried in a finely divided and uniformly distributed state by means of air which is blown on to the paper. This may be effected by an atomizing device 3 in which air, compressed by a pump 5 driven by the machine, passes from a storage bottle 4 so as to direct a moistening mist on to the roll of paper 1. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the treatment of webs of paper in machines other than paper bagmaking machines and the use of moistening materials other than water atomized by gaseous media other than air.
