Patent GB-492479-A (GB)
Title: Improvements in or relating to methods of coating metal articles
IPC: B05D7/22
Filed: 1937-07-20
Abstract: In a method of making coated metal containers, particularly cans for foodstuffs, in which the metal blank for the can is coated with two or more coats of resinous material, there is applied to the blank, after the first resinous coating has dried, a lubricant which is miscible with the composition used for the over-coat and which is a non-solvent for the first coat, and the blank is then shaped prior to the application of the over-coat. The under-coat may be baked before the application of the lubricant, and the latter may consist essentially of a non-volatile plasticizer for the resin of the over-coat and a liquid which evaporates under the heat of the dies used to shape the blanks.  According to an example, the undercoat comprises an oil-free phenol-formaldehyde resin which is insolubilizable by heat, an alkyd resin plasticizer and a solvent, and the lubricant is an emulsion consisting of butyl-cellosolvestearate, morpholine and water.  The shaping dies generate heat which partly or wholly vaporizes the water from the emulsion.  The top coat, which is then applied, consists of Vinyloid H resin, dibutyl-cellosolve-phthalate, methylethyl ketone and toluol. Other specified plasticizers for use in the lubricant are triethanolamine oleate, butyl-cellosolve-phthalate and butyl phthalyl butyl glycolate.  Specification 468,382, [Group IV], is referred to.

Title: Means for consecutively discharging two or more gas-holders into a common supply main
IPC: F17C13/04
Filed: 1920-07-09
Abstract: 148,201. Pintsch Akt.-Ges., J. May 20, 1919, [Convention date]. Void [Published under Sect. 91 of the Act]. Gas distribution systems.-Two (or more) gasholders 1, 2 are discharged successively into a common supply pipe 10 through cut-off valves 22, 23 located in reducing-valves 5, 6, the reducing valve 5 of the holder 1 about to be discharged being so loaded that the resulting gas pressure acts through a pipe 9 on valve 23 in connexion with holder 2 and holds it closed until the pressure has fallen to a predetermined point. The cut-off valves 22, 23 are operated by levers 18, 19 secured to diaphragms 12, 13 controlled by setscrews 16, 17. If gas-holder 1 is being discharged before gas-holder 2, the pressure at which diaphragm 12 opens valve 22 is so adjusted as to be slightly higher than the corresponding pressure at which valve 23 is opened, thus until the pressure in valve 5 falls to below the pressure in valve 6 the higher pressure in valve 5 acting through pipe 9 tends to keep valve 23 closed by its upward pressure on diaphragm 13, and prevent the gas from holder 2 reaching the main 10.

Title: Improvements in bevel gears and in methods of producing the same
IPC: B23F9/10
Filed: 1929-07-02
Abstract: 336,220. Mammano, B. July 2, 1929. Gear-cutting; milling - cutters. - Bevel gears having curved teeth are cut by a method wherein the tooth flanks are generated by the point of a tool 1 which rotates round a fixed axis while the blank rotates in timed relation to the tool and has its axis' inclined at the pitch cone angle to the plane of movement of the tool. In Fig. 1 four tools I - - IV rotating uniformly round a fixed axis 0 are shewn in operative relation with four gear blanks which rotate in the direction of the arrows f<1> - - f<4> about inclined axes O<1>, P<1>, O<4>, P<4>, the points P<1> - - P<4> representing the pitch cone apices. The blank speeds are such that the tools I - - IV respectively trace the cycloidal curves S<1> - - S<4> on the blanks and, after a tool head rotation of 90‹ the tool IV reaches the position 1 and then cuts the next succeeding tooth on the blank a and each of the other tools similarly cuts the next successive tooth on its particular blank. Any number of tools and blanks may be employed and in some cases the blanks R may be arranged on either side of a double-sided tool head D as shown in Figs. 4 and 5. The ratio of the angular speed of each blank and the angular speed of the tools must be equal to the ratio between the number of teeth of the gear and the number of tools. In some cases one tool may cut one tooth flank and the next tool the opposite flank of the same tooth. The curves S<1> are epicycloids when the tools are arranged as in Fig. 1 but by other relative dispositions and directions of rotation of the tools and blanks, teeth having other cycloidal or trochoidal longitudinal curves may be cut. In the particular case where the rolling circle of the cycloidal system (represented by the circle described by a tool point I) is of half the diameter of the base circle (represented by the crown wheel) and is arranged to roll. on the inside of the said base circle, straight tooth forms may be generated. In addition to the rotations of the tool and blank required to produce the longitudinal curve of the teeth, the blanks are rolled on the imaginary crown gear represented by the tools in order to generate teeth of involute profile in cross section. In all cases the finished profile is generated by the extreme point of the tool so that all sections of the basic crown wheel by planes parallel to the pitch plane give superposable cycloidal curves. The finishing tools may however be associated with roughing tools arranged along spiral lines as described in Specification 331,973. The tools may be ordinary pointed tools or milling or grinding tools.

Title: Improvements in tap changing systems for electric transformers
IPC: H01F29/04
Filed: 1929-07-02
Abstract: 315,408. Associated Electrical Industries, Ltd., (Assignees of Hill, L. H.). July 14, 1928, [Convention date]. Systems depending on static transformers.- The voltage ratio between the circuit connected to the high tension winding 2 and that connected to the low tension winding 3 of a. power transformer is regulated by means of tapping switches 14 - - 19 associated with the winding 32 of an autopreventive transformer the mid-point of which forms one terminal of the low tension circuit, this winding being inductively associated with a winding 36 connected through switches 37, 38 to windings 34, 35 inductively associated with the main transformer and arranged to supply to the low tension circuit small amounts of positive and negative boost at each tapping position. For example, with switches 14, 37 closed, the voltage between terminals 7, 8 corresponds to the voltage between terminals 7 and tap 9 less the amount of boost supplied by winding 34. Voltage is increased by an amount corresponding to a fractional value of that between adjacent taps by opening switch 37 to remove the boost. A further increase is obtained by closing switch 38 thus adding to the voltage between terminal 7 and. tap 9 a small amount of positive boost due to the winding 35. The next increase is obtained by closing switch 15 thus providing through the medium of the winding 32 a voltage corresponding to a tap mid-way between taps 9 and 10, the windings 34, 35 being disconnected at this position. Further increases by small steps up to a value corresponding to a tap position 10 are obtained by opening switch 14 and employing windings 34, 35 as before.
