Patent GB-533185-A (GB)
Title: Improvements in radio beacons
IPC: G01S1/02
Filed: 1939-10-14
Abstract: 533,185. Directive wireless systems. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and SMITH, S. B. Oct. 14, 1939, No. 27933. [Class 40 (v)] In a radio-navigational system of the overlapping- beam type, the middle course is further narrowed in width by periodically' varying the directivity of the equi-signal area 8, Fig. 3, through a smaller angle #. The possible limits of deviation are thus reduced from the zig-zag course marked b to that marked a in Fig. 4. In a beacon transmitter in which only one beam is emitted at any instant, the desired effect is obtained by oscillating the aerial system mechanically through a small angle by means of an eccentric link and worm gearing. Alternatively the radiated beam may be periodically changed in direction by varying the phase of the high-frequency currents fed to it.
Patent GB-228832-A (GB)
Title: Improved process for the dehydration of volatile fatty acids
IPC: C07C51/46
Filed: 1923-11-06
Abstract: 228,832. CoppÚe, E. Nov. 6, 1923. Acids, concentrating.-Volatile fatty acids, such as formic acetic, propionic and butyric acids, are dehydrated by distilling in presence of toluene or of an ester such as methylbutyric ester. Vapours of toluene or ester and water pass over and leave a concentrated acid as residue. The vapours on condensation yield a liquid which separates into two layers; the aqueous layer is rejected and the other is returned to the still. The aqueous layer and the residual acid may be passed through separate distilling columns to separate traces of the added liquid. Aqueous acid is introduced by a pipe 1 into a column 2 heated at the base. The vapours evolved are passed by a pipe 6 into the base of a column 7 the plates of which contain toluene or ester. The vapours from the top of this column pass by a pipe 9 to a cooler 10 and the condensate passes into a separating vessel 11, from which the layer of toluene or ester is returned to the column 7. The aqueous layer from the vessel 11 may be passed into a column 16, the vapours from which pass into the cooler 10. The concentrated acid from the base of the column 7 may be passed into a column 22, the vapours from which pass into the column 7. When the residual liquid from the base of the column 2 retains small quantities of acid, the liquid is treated with steam under pressure, and the vapours are passed into a column containing lime, soda, potash or alkaline carbonate. The solution of salts obtained is concentrated and the salts decomposed by hydrochloric or sulphuric acid to liberate fatty acids which are introduced into the aqueous acid to be concentrated.

Title: Improvements relating to means for effecting a saving in fuel in internal combustion engines
IPC: F02M25/022
Filed: 1921-10-21
Abstract: 191,837. Hyvert, J. Oct. 21, 1921. Superheating by gases other than furnace gases. -The heat of the exhaust gases of an internalcombustion engine is utilised for generating saturated steam, which is superheated to a temperature of about 700‹ to 800‹ C., then mixed with a combustible mixture, and admitted to the engine cylinder. The exhaust gases are passed through tubes or coils in a generating chamber and a superheating chamber, and may then pass to a condenser for recovering the water. In one form, Fig. 1, the exhaust passes from a pipe 5 through coils 3, 6 located in the chambers 1, 2. Water is sprayed on the coil 3 from a water pipe 10, and the resulting steam is conveyed to the super-heating chamber 2 by a pipe 12 having apertures 13 within the coil 6. The superheated steam passes by. an outlet pipe 16 to the inlet manifold of the engine. In Fig. 2, the coil 6 is enclosed within a tube 7 coiled about the generating chamber 1, the annular space between the tubes forming the superheating chamber. The chamber 1 and coils 6. 7 are enclosed in an outer casing 20, into which the superheated steam escapes through perforations 18 in the tube 7. In a further form, Fig. 3, water is sprayed into a generator chamber 1 enclosing three parallel pipes 3, 3<1>, 3<11> supplied with exhaust from chamber 24. The pipes 3, 3<1>, 3<11> are continued through superheating coils 7, 7<1>, 7<11> in an outer casing 25, which has an outlet 15 for the superheated steam and a removable plug 27 for inspection and cleaning.

Title: Improvements in the surface or edge treatment of laminates
Inventor: DOWNING TOM ANTHONY
IPC: B32B27/00
Filed: 1959-08-19
Abstract: 901,541. Laminates. IMPERIAL CHEMICAL INDUSTRIES Ltd. Aug. 3, 1960 [Aug. 19, 1959], No. 28360/59. Class 140. [Also in Groups I and X] The surfaces or edges of laminates made from condensation products of phenols (with or without minor proportions of urea) and formaldehyde reinforced with paper, glass fibre or asbestos are treated with vinyl-trichlorosilane, preferably in solution in a solvent such as toluene, benzene or xylene, and the treated parts, after drying, are subsequently bonded to polymethylmethacrylate with a liquid cement comprising methylmethacrylate monomer or partial polymer. The cement may include catalysts which are heat-sensitive, such as benzoyl peroxide or lauroyl peroxide with or without a tertiary amine, or azo compounds such as α,α<SP>1</SP>-azodiisobutyronitrile, or are lightsensitive, such as benzoin, acetoin, butyroin, and diacetyl. The bonding may be face-to-face to form polymethylmethacrylate - faced laminates, the cement being formed as a pool on one surface and the other surface being pressed into contact with it, or, where the surfaces are not flat, being injected between them with a syringe. Constituent laminates surfaced with melamine resins must first have the surface removed to expose the phenolic resin beneath. Bonding may alternatively be edge-to-edge; for example a panel of polymethylmethacrylate may be cemented, for example, as a window, in an aperture in a phenolic resin laminate, the edges of which have been treated with an organic solution of vinyl-trichlorosilane, dried, and then covered with a dough of polymethylmethacrylate and methylmethacrylate monomer. The panel may be pigmented and/or may be shaped for example as a dome. In a further modification the panel may be softened in situ, for example by radiant heat, and shaped as by blowing, vacuum-forming, or die-pressing, with or without a female mould, to form, for example, a sink unit. As shown, an apertured paperphenolic resin laminate 1 on plywood 2 has secured beneath the edge of the aperture, by cement 4 applied according to the invention, a polymethylmethacrylate panel 3 supported by a screwed-on block 5. The panel 3 is subsequently softened and blown against a mould surface to form a sink unit, the edge of which is filled with mastic 6. In another construction the components 1, 2, are cut away at the edge of the aperture to form a recess having an upstanding rib, and the panel is grooved to fit over the rib and slightly chamfered on its lower edge to accommodate cement applied to the engaging surfaces according to the invention, the panel being finally blown to shape as above.

In a machine for feeding strip stock 23 from a coil 11 to a machine which consumes the strip intermittently e.g. a punch press, shears or stamping machine, a variable length loop of the strip is suspended beneath the coil 11. In a first embodiment the coil 11 is supported on a continuously rotating expansible arbor 12 and the strip 23 leaves the coil 11 and passes over support rolls 21, through a washing and straightening device 24 having brushes 37, 39 and straightening rolls 42, and along a variable length loop to intermittently rotating feed rolls 30. The strip may be supported after straightening by a support 59 which can be moved into operative position by piston and cylinder 62. The size of the loop may be controlled by an arm 65 which operates a switch 67 to control the speed of the arbor 12 or the feed rollers 30. The coil 11 is loaded on to the arbor 12 by a cradle 14 running on rails 15 and the free end of the strip is guided to the feed rolls 30 by rollers 48<11> which are moved to an inoperative position 48 by piston and cylinder 56 and lead screw 53 driven by motor 54.
