Title: Improvements in or relating to flexible tube pumps
IPC: F04B43/02
Filed: 1951-01-17
Abstract: 682,225. Flexible tube pump; speed of governors. MAILLOT, L. A. Jan. 17, 1951 [Jan. 17, 1950: May 24, 1950], No. 1313/51. Classes 57 and 110(ii) The pump chamber comprises an elongated tube having a single deformable wall 3 of plastic material or metal, the other walls being rigid, the wall 3 being subjected to a succession of pressures from piston-pushers 4 caused by the passage of rollers 5. Alternatively the tube may be in a flattened, closed, condition under spring pressure Fig. 11 (not shown) the wall 3 being deflected by a roller-pressed pusher forcing down the spring at one or more places on the tube. Synthetic rubber or poly-tetra ethylene fluor may be used for the tube. Fig. 2 shows a roller 5, carried by a rotor 13, which bears on pushers 4, to flatten the wall 3 which, in its free position, is supported by an annular abutment 17. The inner edge of each pusher is supported by an edge 18. Adjustment of the pumping capacity is caused by vertical adjustment of the rotor, relative to the pump stator, by means of an arm 22 or by an adjustable wall 11 at the back of the pushers. An inlet 7 leads to passages 6, supplying the pumping chamber and discharge passages lead to an outlet 9. Fig. 6 shows a pump for injecting fuel into the cylinders of an internal-combustion engine, the number of working chambers being'equal to the number of engine cylinders. The size of each working chamber is governed by a diaphragm 42 which is moved up or down in accordance with pressure variations above and below the diaphragm and the pressure exerted by a spring 43 built up of Belleville washers. The effect of the spring 43 may be varied by altering the number of washers or rotation of a nut 44 by hand or by control of a thermostat. The port 46 may be connected to the atmosphere or to a vacuum pump or bellows. Fuel enters through a port 7 and an annular passage 50 and is delivered through a number of outlets. The supply may be under control of a pressure governor Fig. 15 interposed between a feed pump and the pump 3. The governor is of a known type having a diaphragm 53 dividing a chamber into two parts, and supporting a needle valve, 66. The needle valve 66 lifts a ball valve 64 when the pressure in the lower chamber 68, leading to the valve chamber of an internal-combustion engine, rises. In a modification a metal disc 34, Fig. 12 (not shown) is inserted between the pusher and the plastic sheet. The plastic sheet may be replaced by a metal one of one or several laminations.

Filed: 1926-01-19
Abstract: 246,181. I. G. Farbenindustrie Akt.- Ges., (Assignees of Chemische Fabrik Griesheim-Elektron). Jan. 19, 1925, [Convention date]. Neutral diazonium salts of 1: 5-naphthalenedisulphonic acid.-Diazo preparations for use in forming insoluble azo dyes on the fibre contain neutral salts of 1 : 5-naphthalene-disulphonic acid with diazonium compounds of unsulphonated substituted aromatic amines. Advantageously other suitable compounds such as metallic salts of arylsulphonic acids may be added. The diazonium salts prepared from negatively substituted amines, particularly the negatively substituted aminophenylethers, are especially useful. The preparations are particularly useful when employing 2 : 3-oxynaphthoic arylides for producing shades on the fibre. The salts are prepared by double decomposition of aqueous acid diazo solutions with metal salts of the disulphonic acid. In an example, neutral 1:5-naphthalenedisulphonate of o-chlordiazobenzene is mixed with aluminium sulphate and sodium benzenesulphonate; neutral 1 : 5-naphthalenedisulphonate of diazotized dianisidine is also mentioned, and disodium 2 : 7-naphthalenedisulphonate is referred to as a further example of a suitable aryl sulphonate. Specification 15884/15 is referred to. The Specification as open to inspection under Sect. 91 (3) (a) comprises an additional example in which neutral 1 : 5-naphthalene disulphonate of diazotized dianisidine is mixed with partially dehydrated aluminium sulphate and disodium 2 : 7-naphthalene disulphonate. It also comprises the use of the acid diazonium salts of 1 : 5-naphthalene disulphonic acid and preparations made therefrom, which now forms the subject-matter of Specification 269,212. This subject matter does not appear in the Specification as accepted.

Title: The control of a gas flow as a function of the position of a standing shock-wave in the gas
Inventor: BULLOCK LESLIE
IPC: F02C7/057
Filed: 1964-01-14
Abstract: 1,080,951. Automatic control of shock waves. HAWKER SIDDELEY DYNAMICS Ltd. Jan. 14, 1965 [Jan. 14, 1964], No. 1621/64. Heading G3R. [Also in Division F1] An aircraft gas turbine engine has a rectangular cross-section intake duct 1 leading to the engine compressor 12. In order to maintain the air mass flow to the compressor constant at a predetermined value corresponding to a predetermined position of a standing shockwave 6 resulting from supersonic flight, a temperature sensitive probe 10 is positioned at the desired position of the shockwave and any deviation of the shockwave from this position is sensed to cause adjustment of a vent 4 and a return of the shockwave to the desired position. The sensing mechanism includes additional temperature probes 9, 11 disposed respectively upstream and downstream of probe 10. An electrical signal corresponding to the average temperature measured by probes 9, 11 is transmitted from an averaging unit 13 to a unit 14 for comparison with the signal from probe 10. Any deviation of the shockwave 6 from its desired position causes a change in signal from probe 10, the resulting error signal passing to an amplifier 15 and to an electro-mechanical or electrohydraulic motor 16 controlling the vent 4. A negative-feedback line 17 stabilizes the system. The invention is applicable also to the control of gas flow through an aircraft engine exhaust duct into the atmosphere according to the position of the shockwave associated with the flow.

Abstract: 1,171,003. Automatic winding and doffing of lap. TOYO BOSEKI K.K. and KANPATSU KOGYO K.K. 11 Jan., 1967 [14 Jan., 1966; 18 March, 1966; 22 April, 1966], No. 1632/67. Heading D1N. In an automatic lap winding and doffing machine a pair of piston actuated supporting members 1 carried by swing arms 2 mounted on the machine frame support a mandrel in contact with a single rotating lap roller 4 for winding lap onto the mandrel by frictional contact with the lap roller while loading the mandrel towards the lap roller with uniform pressure at all times during the winding by a piston device 3. When a full package of lap has been wound the loaded mandrel is released from members 1 and it rolls forward on to a delivery conveyor 29, due to its positioning slightly forward of the roller 4. A further empty mandrel 101 disposed in a pivotally mounted, piston actuated, receiving member 105 which is fed with mandrels from a mandrel supply rack 102, is brought into the winding position in contact with roller 4 by turning the receiving member 105. Meanwhile a cutting member cuts the lap where it extends between the full mandrel and the empty mandrel and the free end of the lap is then tucked around the empty mandrel. The cutting device (Fig. 5) may consist of a curved plate 31 of same diameter as an empty mandrel and provided with a comb 32, the device being moved by a rack and pinion arrangement 34, 35 actuated by a piston 56 in a circular path to so cut the lap and then press the lap end with curved end 33 of plate 31 around the empty mandrel. Alternatively the lap is cut from above and a separate piston actuated plate 99 (Fig. 14E) serves to tuck the lap end around the empty mandrel. The transverse width of the lap fed from rollers 26, 26<SP>1</SP> to the mandrel is reduced first before the full lap package is formed by a device 131 (Fig. 10) in which a pair of guide plates 130 are moved together by energizing an electromagnet 141.
