Abstract: 492,367. Bottling. MEADOWCROFT & SON, Ltd., W., and MEADOWCROFT, W. Dec. 16, 1936, No. 28096. [Class 125 (ii)] In a counter-pressure filling-machine, the passage through which liquid is discharged from the reservoir A is provided with an upstanding flange e and over this is situated a sealing cap K, by which means foreign matter cannot pass from the bottle into the reservoir, being trapped at this point and flushed out at the next filling. Further, the gas-supply and pressure-equalizing tube G which passes through the liquid-supply passage projects into the bottle and is provided with lateral passages g<1> so that any foreign matter which may enter the tube, is blown out when the succeeding bottle is being filled. In the form shown, the pressureequalizing tube G is capable of vertical movement, being carried by the weighted lever m, and it carries the liquid-supply valve B; the gas-supply valve J<1> is located at the upper end of the tube G, being suspended from a lever j<4> and held with limited vertical movement by a cap j<2>, the levers j<4> being weighted so that they tend to hold both their respective valves in the open position ; in the cover of the reservoir A there is mounted a shaft n<3> carrying the actuating star wheel O at its upper end and at its lower end a pivoted cam member N which engages projections j<5>, j<6> on the lever j<4>. The following is the sequence of operations : both valves B, J<1> are held closed by the cam N engaging the projection j<6>; rotation of the cam through 180‹ rocks the lever j<4> so opening the gas valve J<1>, the liquid-supply valve B remaining closed ; rotation of the cam N through 90‹ frees entirely the lever j<4>, and the gas pressure in the reservoir and the bottle now being equalized, the liquid-supply valve B opens.

Title: Improvements in or relating to the driving of alternating current generators
IPC: H02K7/02
Filed: 1927-10-22
Abstract: 304,629. Funga, F. Oct. 22, 1927. Dynamos, driving.-In driving an alternating- current generator from a variable-torque prime mover, such as a gas-engine, by means of a resilient coupling, the coupling is so designed that the torque produced by it when turned through a given angle is substantially less than the synchronising torque produced when the generator is out of step by the same angle. The coupling is preferably arranged between the flywheel of the prime-mover and the generator, and the Specification defines certain "critical speeds" arising from the, relations of the various parts of the apparatus and their most satisfactory relation to the operating speed. The coupling may be made to act as a rigid coupling, by means of an electromagnetic clutch or otherwise, during starting and stopping. A step-up gear may be interposed between the resilient coupling and the generator.

Title: A process and machine for the automatic boring and turning of thread-reels
IPC: B23B5/00
Filed: 1924-11-26
Abstract: 248,068. Cronstr÷m, H. Nov. 26, 1924. Combined turning and drilling machines.-In a process of and machine for making wooden reels, the roughly-turned blanks are fed from a hopper through a vertical tube to a self-centering drilling head, where the blank is drilled by a reciprocating drill and then transferred to a lathe where the external surfaces are turned and the finished reel ejected. The blanks are shovelled into an opening in a floor under which is a hopper 2 from which the blanks are fed to a tube 4 in a continuous vertical column by the mechanism described in Specification 248,296. At the bottom of the tube the blanks drop successively on to a platform 19 where they are gripped by claws 14 on a sector 13 which is swung to present the blanks horizontally to a chuck in readiness for the drilling operation, the construction of the chuck being described in Specification 248,297. Faulty blanks are automaticalily rejected before they reach the chuck. The blank is dropped by the claws 14 on to a cushion 31 whence it is pushed into the chuck by a push rod 33. The drill is mounted in a spindle 59, Fig. 4, adjustable in a sleeve 61 which is rotated by a pulley 67 drawn from a motor 69. Axial movement of the drill is effected through a bracket 75 adjustably secured to a shaft 78 connected by a rod 84 to a swinging lever 85 which also actuates the pusher 33. The lever 85 is oscillated from a second lever 88 with which is incorporated a resilient device as described in Specification 248,293, so that if the drill encounters an impenetrable obstruction, the yielding device operates and the detective blank is ejected undrilled. After the drilling is completed, the drill is withdrawn and subsequently the blank is pushed on to an incline 112 down which it rolls to the lathe where it is fed to the lathe centres by means described in Specification 248,300. The lathe is described in detail in Specifications 250,139 and 251,203, the feed of the turning tools being progressively lessened so that a finely finished reel is obtained and subsequent polishing is unnecessary. The finished product is finally pushed off the spindle and falls into a box beneath the machine. The lathe is driven by a separate electromotor 207.

Class 146(2) In a chart casing comprising two transparent protective covers hinged together at one edge and provided with a locking arrangement at the opposite edge, with at least one luminescent sheet between the covers, one cover has a smooth and the other a matt surface. The chart is placed between the luminescent sheet and the transparent cover, and when two charts, and therefore two luminescent sheets are used the latter may be different, e.g. the one for use with the smooth disc giving a strong illumination for a short duration, and the other a less intense light for a longer time. A reflector screen may be used behind the luminescent sheet and may be attached thereto. The smooth cover may be fitted with an orientation compass with a rotatable compass scale. A pencil pocket may be provided. All parts, especially the luminescent sheet, must be non-magnetic, the joining and latching means being formed of leather &c. strip attached, for example, by brass rivets. A luminescent sheet may be carried by the matt cover when, no chart is to be used therebetween. The chart is retained in position in the casing by flexible tapes or rubber bands. Self-illuminating points or directing lines, for orienting the chart in the case, may be arranged on one or both sides of the casing. A carrying strap is threaded through eye-. lets in the casing.

[A Specification was laid open to inspection under Sect. 91 of the Acts, April 21, 1938.] [Class 26] [Also in Groups X and V] The walls of a swimming-bath are first coated with a layer containing bitumen, and then with a wear-resisting layer comprising about 5 parts of a filling-material, such as cork, which does not absorb water and preferably is light in weight, one part of sand, two parts of cement, two parts of a bitumen-water dispersion containing some filling-material, and two parts of water. The initial layer may be applied in two layers, the second of which is less dilute than the first and is applied after the first is partly dried.
