Title: Improvements in methods of and apparatus for filling bottles with aerated liquids
IPC: B67C3/06
Filed: 1933-11-21
Abstract: 429,268. Bottling-machines. BLAXTER, A. P. L., and BLAXTER, C. G., c/o Barnett & Foster, Eagle Wharf Road, Hoxton, London. Nov. 21, 1933, No. 32512. [Class 125 (ii)] A rotary machine for filling bottles &c. with aerated liquids comprises a number of filling heads 30 and a valve 24 which controls the supply of compressed air from a reservoir 28 and a valve 26 for controlling the escape of compressed air to the atmosphere. The controlling valve 24 intercepts the discharge of compressed air from the bottle to the atmosphere prior to the interruption of the flow of aerated liquid, so that compressed air is trapped in the bottle above the liquid level therein. The bottle is initially charged with compressed air at a pressure higher than that of the carbonated liquid and the air pressure in the bottle is so maintained that the liquid only trickles therein. The controlling means comprises a multiported disc valve 4 and a leather valve disc 5, the ports of which are adapted to establish connections between the bottles and the filling heads, and the compressed air and aerated liquid supplies. A compressed air dome 1 is bolted to a casting 2 which supports the filling heads 30. The pipe 7 charges the bell with compressed air at a pressure higher that that of the carbonated liquid. A pipe 9 for carbonated water leads to the valve 4, and an air discharge pipe 11 is also connected to the valve 4 and to a snift pipe 13. The pipe connections on the valve communicate with ports in the valve disc. On rotation of the casting 2 the ports 22 are moved successively into communication with the carbonated water port 20 in the disc, while the ports 23 are moved successively into communication with these three other ports in the valve disc 5 for the purposes stated.

Filed: 1920-11-25
Abstract: 176,084. Schat, A. P. Nov. 25, 1920. Brakes for winding and paying-out apparatus. -An anchor capstan or windlass is provided with brake mechanism in which the brake is applied by the tension in a bight in the anchor chain under the control of manually-operable means. As shown in Fig. 1, the chain a passes from the lifter 1<b> under a roller 4 over the bow stopper 3 and through the hawse pipe 2. The roller 4 is carried at the end of one arm of a lever 6 pivoted at 7. The ends of a brake band 8 are attached to the other arm of the lever and a hand-lever 9 is secured to it at its fulcrum. The tension in the bight formed by passing the chain under the roller 4 tends to apply the brake and the hand-lever permits manual control. In one of two modifications in which the capstan is vertical, the roller 4, Fig. 4, is carried by a link 6<a> attached to a pivoted arm 6 to which one end of the brake strap is also attached, and the chain is passed round a bollard 10 to form a bight for the roller 4. This brake can be operated by a vertical hand-lever 7 acting on the link 6<a> through a pin and slot connection. In the other, the roller 4 is mounted in one arm on a vertical shaft to another arm on which one end of the brake strap is attached. On the. upper end of the vertical shaft is an horizontally-swinging hand-lever for manual control. Specification 149,175, [Class 115, Ships &c., Rigging &c. for], is referred to.

Title: Improvements in and relating to apparatus for bending vitreous rods or tubing
IPC: C03B23/06
Filed: 1938-11-17
Abstract: 507,734. Bending vitreous rods or tubes. BRITISH THOMSON-HOUSTON CO., Ltd. Nov. 17, 1938, No. 33443. Convention date, Nov. 18, 1937. [Class 56] A machine for bending vitreous tubes or rods to a predetermined curvature, particularly for shaping tubular envelopes for electric lamps, comprises a former having the desired shape of the tubing and mounted close to a furnace, means for moving the tubing into and through the furnace and then into engagement with the former, rollers for pressing the tubing against the former, and means for rotating the former to carry the tubing past the rollers which bend it to the shape of the former. The machine operates on two tubes simultaneously, and these are fed automatically from racks 11, Fig. 2, to positions in front of spindles 12, Fig. 4, with heads 62 which enter and engage the tubes 10 and move them forwards slowly through a furnace 13, Fig. 2. In the furnace, the tubes are softened before their ends pass between rollers 14, 15 and large rollers or formers 16, the edges of which have the desired curvature for the tubes. The spindles then return to their initial position, and the rotation of the formers 16 carries the tubes past rollers 116, 116<1>, 123 and 124 which bend them to the curvature of the formers, the shaped and cooled tubes being discharged on to conveyer. The spindles 12 are mounted on a carriage 18, the movement of which controls the operation of the other parts of the machine. The carriage is moved'along guides by the pistonrod 47 of a cylinder 46. A liquid, preferably oil, is forced into the cylinder 46 from a storage tank by compressed air, valves being' provided to control the rate of flow and therefore the rate of movement of the carriage. While the tubes are being heated in the furnace 13, they are rotated by the spindles 12 which are driven by a motor 81 on the carriage. The spindles are cooled by air which is introduced from a pipe 86 into a chamber 85 through which the spindles pass.

Title: Improvements in circuit arrangements for reducing the influence of fluctuations of mains potential and load on the potential supplied by a rectifier
IPC: H02M7/06
Filed: 1935-12-03
Abstract: 463,992. Converting automatic regulation ; charging and discharging batteries. SIEMENS-SCHUCKERTWERKE AKT.-GES. Dec. 3, 1935, Nos. 33508, 33509, and 33510. Convention dates, Dec. 4, 1934, March 23, 1935, and July 10, 1935. [Classes 38 (ii) and 38 (iv)] Fluctuation of potential of the D.C. circuit 4, Fig. 1, fed from an AC. circuit through a rectifier 3 due to variations in D.C. load and also variations in the A.C. potential, is prevented by means of two transformers 1 and 2 having different magnetic characteristics, their windings being in series on the primary side and in series on the secondary, and one of the transformers having a magnetic biassing winding fed with the rectified current. Preferably, the secondaries are in series opposition although series-additive connection may be used. When a battery 4 is used and the arrangement has a rising voltage characteristic as in Fig. 3, charging will cease at the point D and will not recommence until the battery voltage has fallen to the point E<1> at which point the charging current jumps from zero to J<1>. To cause the characteristic to drop beyond a particular load value, a resistance having a negative temperature coefficient is connected in parallel with the winding 5. In addition, the transformer 2 may be provided with a further biassing winding which is connected through a resistance across the rectifier. By adjustment of this resistance and also the resistance across the winding 5, the shape of the characteristic can be varied. To produce a characteristic having a very pronounced curvature, the biassing windings are connected to act in opposition. To compensate for variations in the rectifier impedance due to temperature changes, a resistance may be connected in parallel with the windings 5 having a similar temperature resistance characteristic to the rectifier. Fig. 10 shows a high voltage arrangement in which the load 20 is fed through a rectifier 3 from a step-up transformer 13, the primary of which is supplied from the series connected secondary windings of the transformers 1, 2, the saturating winding 5 is supplied from a rectifier bridge 14 in series with the primary of the transformer 13, and the saturating winding 7 is supplied through a rectifier 16. Resistances 15, 19 enable adjustments to be effected. The Specification as open to inspection under Sect. 91 also states that an A.C. load could be supplied by omitting -the rectifier and transformer 14. This subject-matter does not appear in the Specification as accepted.
