Title: Pumping apparatus incorporating a centrifugal pump
Inventor: SERGENT ANDRE
IPC: F04D9/00
Filed: 1969-03-19
Abstract: 1,268,245. Centrifugal pumps. A. SERGENT. March 19, 1969 [March 22, 1968], No. 14533/69. Heading F1C. In a pumping apparatus comprising a centrifugal pump receiving liquid through a pipe 6 from a chamber 1 supplied with liquid through a pipe 2 from a tank (not shown), the pump impeller 12 is automatically moved axially along shaft 13 in a direction away from the pipe 6 to reduce the effectiveness of seal 16 and thereby the output of the pump, when there is a drop in the liquid level in the chamber 1. Thus drainage of the chamber 1 and consequent ingress of gas or vapour into the pump is avoided. The axial movement of the impeller occurs when a cavity 10, normally at pump discharge pressure, is communicated through a pipe 7 with the chamber 1 by automatic opening of a float-controlled valve 8 due to the drop in liquid level in the chamber 1. If the supply to the chamber should cease, the impeller moves axially as described and the consequent lowpressure developed by the pump is insufficient to maintain a spring-loaded valve 20 in its open position. Thus some liquid is retained and the pipe 6 is kept full. The chamber 1 has a float-controlled vent valve 4. The wall member 19 of a continuously-effective seal 17 may be of the same diameter as that of the impeller and arranged so that the impeller channels are partly or completely closed when the impeller moves axially from its normal operating position. The impeller may be of the open type. The flow through the inlet duct 2 may be accelerated by a screw-type impeller or by a nozzle connected to the pump discharge. Alternatively, a partition may be provided in the upper portion of the chamber 1 below the valve 4, the position having a non-return valve therein coupled to a float.

Abstract: 711,058. Cigarette-making machines. KORBER, K., and KOPER, E., [trading as KORBER & CO., KOMMANDIT-GES. K.]. June 21, 1951 [Feb. 12, 1951; March 2, 1951; March 16, 1951; March 16, 1951], No. 14724/51. Class 130 In a continuous-rod machine in which a tobacco stream is conveyed upwards round the periphery of a conveyer disc 1 rotating about a horizontal axis, between a paper web 10 on the periphery and an outer supporting belt 3, the belt 3 is caused, by co-action with suitable beltprofiling means provided in front of and around the disc 1, to have a laterally waved profile as it passes round the disc 1 whereby the belt surround the stream and confines it to the central part only of the web. As shown, a belt-profiling former 6 is part of the trough 5 into which tobacco is showered to form the stream, and is shaped as in Fig. 4 so that the sides 3a of the belt 3 are clear of the stream T. On passing on to the disc 1 the belt tension in combination with the shape of the disc periphery causes the parts 3c, Fig. 7, of the belt to form projecting ribs which press down on. the web 10 to achieve the purpose of the invention. The lateral section of the periphery of the disc 1 may be a concave curve, Fig. 7, with or without a flat bottom to receive the paper 10. The periphery may have, to receive the paper, a recess 1a, Fig. 8, which may extend sufficiently to retain the edges of the belt 3 also, or these may be accommodated in further recesses 1b. Where such recesses are provided the outer portions 1, Fig. 8, of the periphery may be of V-shape in section as shown, axially disposed, or rounded or bevelled down, and guide rolls or strips 14 may be provided where the belt 3 runs. on to and off the disc 1. The ribs 3c may be additionally held down on the disc periphery by circular section guides fitting into the ribs. Ribs 1c, Fig. 13, may be provided on the disc 1, with or without recesses 1b, to assist in a wave-like belt profile formation. On running off the disc 1 on to a support 11a recessed to receive the web 10 the belt 3 passes over a roller 16 having a groove 16b, Fig. 15, receiving the tobacco-holding portion of the belt, and which may have recesses 16d corresponding to the recesses 1b or be formed with projecting circumferential ribs on either side of the groove 16b. The direction of movement of the belt 3 is then reversed by rollers 7, 8 which may have grooves of successively diminishing size, and the belt returns over cylindrical rollers 9. The roller 7 may be omitted. The tobacco stream finally enters apparatus 11 which folds the paper 10 round it to form a cigarette rod. A scraper 20 is provided to clean the belt 3. In Fig. 2 (not shown) the machine is provided with a further endless belt which passes round the periphery of the disc 1 between it and the paper web and carries the web over rollers into the rod-forming apparatus, the rollers 7 and 8 being dispensed with and the roller 16 replaced by a roller 9.

Title: Tele-compass with soft iron
Filed: 1922-05-25
Abstract: 180,684. Soc. des Etablissements Gaumont. May 26, 1921, [Convention date]. Void [Published under Sect. 91 of the Act]. Tell-tale apparatus.-A compass specially suitable for use on ships or aeroplanes comprises a soft-iron ring fixed in position away from disturbing influences such as masses of iron and provided with fixed windings excited by alternating-current. The effect of the earth's field superimposed on the variable field produces variations in current which indicate at a distance the direction of the earth's field with respect to the fixed ring. In one example, the fixed coil carries a primary winding fed by alternating current and a secondary winding tapped at three equidistant points and connected similarly to a closed coil. A search coil in the field of this coil is in series with a telephone and sounds are heard except when the axis of the search coil is at right-angles to the line corresponding to the direction of the earth's field. In a modification, the primary winding of the fixed ring is omitted and alternating current is supplied to a coil at right-angles and fixed to the search coil. In a further modification the fixed ring is composed of insulated iron wire fed by alternating current. In a further modification, Fig. 4, both transmitter and receiver comprise a fixed ring 1, 1<1>, of insulated iron wire fed by the alternating-current source 3 and provided with star-connected windings 4, 4'. Sounds are heard until the pivoted magnet NS is put parallel to and in the same sense as the earth's field. In all these cases the iron ring may be replaced by other shapes, such as a cable surrounding the vessel or the wings of an aircraft, the receiverbeing altered correspondingly. Arrangements may be made whereby the search coil or magnet sets itself automatically to indicate the North and South line, either of its own accord or by means of relavs and servo-motors. Several transmitters or receivers may be used at once.
