Class 64(iii) A heat exchanger in particular for liquids, comprises a plurality of series-connected jacket pipes 25-30 (Fig. 1) through each of which a set of tubes 31 (Fig 3) extends, a tube in one set being connected either to another tube in the same set or to a corresponding tube in another set by bent or elbowed tubes provided externally of the jacket pipes and having a cross-section substantially the same as that of the tubes 31. In Figs 1 and 3 the sets of tubes 31 in adjacent jacket pipes are provided at each end with tube plates 33 and are interconnected by sets of U-tubes 36 united at their ends to tube plates 35 which are bolted together with the tube plates 33 to flanges 32 provided at each end of the jacket pipes. Alternatively (Fig. 9) the tubes within the jacket pipes may extend back and forth within the same pipe e.g. from an elbow 54, through the jacket pipe 50 to return bends 56 and back through the same jacket pipe to the elbow 55. Fig. 1 shows an arrangement for heating water in a laundry by hot waste water. The valves 45 and 22 are normally closed and the valves 49, 21 are normally left open. Hot waste water is drawn from a sump 10 by the pump 17 and passes to a header 23, and thence in series through the pipes 31 of each jacket pipe to a header 24 leading to the waste pipe 47. Meanwhile fresh water to supply the laundry washing machines flows through the jacket pipes in series from an inlet 39 to an outlet 38 leading to the point of use. By closing the valves 49 and 21 and opening the valves 45, 22 the flow of hot waste water through the pipes ment which may have collected in the header 23. An arrangement for automatically and periodically reversing the flow of hot waste water through the pipe 31 is described Figs. 5 to 8 (not shown), and in this form the jacket pipes and their associated tubes 31 are arranged in two adjacent banks. In an arrangement Fig. 10 (not shown) for cooling mash and mixing slop and. mash in a distilling process, slop is cooled in one set of tubes and jacket pipes and is mixed with mash entering a further set of tubes and jacket pipes, cooling water passes serially through both sets of jacket pipes, a connection being made from the water supply pipe to the inlet pipe leading to the sets of tubes so that the tubes may be flushed out when required.

Patent GB-1082064-A (GB)
Title: Process for treating glass
Inventor: STACEY MARTIN HUGH
IPC: C03C21/00
Filed: 1965-02-18
Abstract: To strengthen glassware, the surface is first etched with an aqueous solution of one or more acid, the etched glass is then subjected to the action of high vacuum, i.e. at pressures less than 0.1 millimetres of mercury, and finally to a cation-exchange treatment whereby cations in the surface layers are replaced by cations that occupy a larger volume, The glass may also be etched in a further step after the high vacuum treatment and before the cation-exchange treatment, such etching removing a layer of about 10 microns as against removal of about 50 microns in the first etching.  Etching is normally by HF alone or with H2SO4, the glass then being washed with distilled water and acetone.  The high vacuum is maintained for about 1 hour when the glass is heated, for example to 300 DEG  C. or for about 6 hours at room temperature.  For soda/lime glass, the cation-exchange treatment is by molten KNO3 at about 430 DEG  C. for 1 hour.

Title: Improvements in or relating to the manufacture of plastic artificial materials
IPC: C08F8/00
Filed: 1936-03-09
Abstract: Plastic masses soluble or swellable in water are prepared by partial saponification of wholly or partially polymerized acrylic or methacrylic esters.  Other polymerized substances or substances such as softeners, cellulose esters, dyestuffs, or turbidifying agents may also be present.  The saponification, which may be effected in solution, in dispersion or as a surface treatment on bodies such as films, is preferably effected by alkalis, alkaline earths, ammonia or amines.  Suitable esters include methyl, ethyl, butyl, amyl and hexyl esters, whilst other polymerisation products such as those of vinyl acetate, chloracetate or chloride may be present or used in the preparation of the polymer.  The products may be used as gelatine substitutes, in particular in the photographic industry, as coatings for textiles or leather, for impregnation and as thickening agents for dyes and sizes.  In examples, (1) polyacrylic acid ethyl, methyl, propyl, butyl, amyl, hexyl or phenyl ester is saponified by heating with alcoholic potassium or sodium hydroxide; (2) a dispersion of polyacrylic acid methyl ester in water is heated with potassium or sodium hydroxide, a softening agent added, such as phthalic acid methyl glycol ester, diethylene glycol monoethyl ether, glycerine ether, and the product cast into films to use as a gelatine substitute; (3) a hot solution of polyacrylic acid ethyl ester in alcohol is stirred with aqueous barium hydroxide to yield a solution which will give an adherent solution on glass; (4) an interpolymer of ethyl acrylate and acrylic acid is saponified with caustic soda; (6) an interpolymer of methyl and n-butyl acrylate prepared in solution in methyl ethyl ketone is saponified with alcoholic potassium hydroxide; (7) a dispersion of polymethacrylic acid n-butyl ester is saponified with sodium hydroxide; (8) a film of polyacrylic acid ethyl ester is treated with lye to yield a mat surfaced product.

Title: Improvements in trigger mechanism for automatic guns
IPC: F41A19/30
Filed: 1947-03-17
Abstract: 622,387. Automatic firearms. REISING, E. G. March 17, 1947, No. 7376. [Class 119] A firearm has a trigger-operated disconnector which actuates a firing hammer sear and extends into the path of a member movable with the breech bolt, the disconnector being fitted with a spring-controlled element which is moved by the member on the bolt to a position in which it constitutes a cam surface for deflecting the disconnector from that member. The element also serves to maintain the disconnector in the " sear-disconnected " position during the last portion of the movement of the bolt towards the breech-closed position. In the form shown in the Figure, the trigger 46 pivoted at 48 and spring-pressed by spring 50 has a disconnector 56 pivoted on it at 54. The notch 58 on the disconnector normally engages a notch 38 on sear 34 which engages the hammer 20 by nose 42. An extension 66 spring-pressed by spring 64 is pivoted on the disconnector. In action, pressure on the trigger pivots the sear anti-clockwise to release the hammer which strikes the firing pin 18 on the breech-bolt 14. On recoil of the bolt, the part 28 carried by action slide 26 and engaging a groove in the bolt contacts the part 66 and the force of the recoil causes it to pivot against its spring so that the action slide rides over the top of it, thus causing the disconnector to be pushed down so that the notch 58 cannot engage notch 38. Only when the bolt returns to the fully-closed position can the part 28 drop back into contact with part 66 and the notches 58 and 38 engage thereby cocking the gun.
