Filed: 1967-02-01
Abstract: 1180414 Metering A O SMITH CORP 1 Feb 1967 [1 Feb 1966] 4959/67 Headings G4D D6Y D6C2 D6M1 and D1D14 In electronic pulse combining apparatus, for example for recording the total amount of petroleum used at a plurality of meters 1, 2, 3, 4 Fig. 1, a switch is closed in each meter when a unit of petroleum is used to switch an associated bistable memory device 14 to its "1" state, the pulse stored therein being fed via an associated transfer gate 15 to a summing circuit 11 when the memory is scanned. In the embodiment described the switch 7 is closed by a cam 8 on the output shaft of the meter. This results in a pulse being applied to the base of a transistor 24, Fig. 2, in the memory unit 14 to cause transistor 23 to conduct and to cut off transistor 24. Each transfer circuit 15 includes a pair of transistors 39, 40 which are such that when the transfer circuit is scanned by a pulse on input lead 17 and a pulse is stored in the memory unit 14 resulting in a positive potential being applied to terminal 18, transistor 39 conducts and transistor 40 is cut-off so that a negative output signal is established at terminal 20 which is applied to a summing unit 11 Fig. 1 and to the reset terminal 34 Fig. 2 of the memory unit 14 to cut-off transistor 23 and drive transistor 24 into its conducting state. The summing circuit operates as a NOR circuit so that for each pluse stored in one of the memory circuits a pulse is applied to a counter 12 Fig. 1.

Title: Omega-chloro-polyfluoroalkane sulphonyl fluorides and derivatives thereof
IPC: C07C309/80
Filed: 1957-06-18
Abstract: The invention comprises omega-chloro polyfluoroalkane sulphonyl fluorides corresponding to the formula:  <FORM:0869922/IV (b)/1> wherein the free valencies on the carbon atoms of the olefinic monomer unit are satisfied by hydrogen, fluorine or chlorine atoms at least two such free valencies being satisfied by fluorine atoms and wherein n is an integer from 1 to 150 or a corresponding sulphonic acid or metal or ammonium salt thereof, acid chloride or sulphonamide and a process for the preparation thereof in which sulphuryl chlorofluoride is reacted in the presence of a free radical initiator with a polyfluorinated olefinic compound copolymerisable with sulphur dioxide.  Free radical initiators specified include organic peroxides e.g. benzoyl peroxide and hydroperoxides, aliphatic azo compounds and ultraviolet light. Polyfluorinated olefinic compounds specified for use as starting materials include 1,1-difluoro-, 1,1-dichloro-2-chloro-, 1,1-difluoro-2,2- dichloro-, trifluoro-, trifluorochloro- and tetrafluoroethylenes.  The process may be carried out batchwise or continuously.  In examples: Compounds of the formula CI(CF2CH2)nSO2F in which n has an average value of 4 or 5 are obtained by reacting 1,1-difluoroethylene and sulphuryl chlorofluoride (1); compounds of the formula CI(CFCICF2)nSO2F in which n has an average value of 18 or 110 are obtained by reacting trifluoroethylene with sulphuryl chlorofluoride (2); compounds of the formula Cl(C2F4)nSO2F in which n has an average value between 4 and 5 are obtained by reacting tetrafluoroethylene with sulphuryl chlorofluoride (3), and similar compounds in which n has a value of 8, 9, 12 or 52 are similarly obtained (4).  The number of olefinic monomer units in the products are varied by varying the proportions of reactants.  The products of the examples are converted to the corresponding sulphonic acids, metal and ammonium salts thereof, acid chlorides and sulphonamides.  Thus the product of Example (3) is converted to the calcium salt of the corresponding sulphonic acid by heating with calcium oxide and water and the zinc, potassium, lithium, ammonium or sodium salt with the appropriate metal or ammonium sulphates.  The corresponding free sulphonic acid is obtained by distilling the calcium salt with sulphuric acid.  The sulphonyl chlorides Cl(C2F4)nSO2Cl are obtained by reacting the acids with phosphorus pentachloride or the salts with a phosphorus pentachloride-zinc chloride complex.  The sulphonamides of the formula Cl(C2F4)nSO2NH2 are prepared by reacting the acid fluorides with liquid ammonia.  Specification 758,467 is referred to.

Abstract: 996,885. Tyre building machines. PNEUMATIQUES CAOUTCHOUC MANUFACTURE ET PLASTIQUES KLEBER COLOMBES. Feb. 9, 1962 [Feb. 10, 1961], No. 5113/62. Heading B7C. In a tyre building machine comprising a building drum formed by a tubular, flexible diaphragm C sealed at its ends to two coaxial discs A, B, which are movable axially away from each other, to tension the diaphragm for building a flat band carcase thereon, and towards each other on inflation of the diaphragm to effect shaping of the carcase, the movements of the end discs are effected by means of a pneumatic jack D housed wholly within the confines of the diaphragm and the discs. As shown in Figs. 1 and 2 the jack D is formed by two telescoping collars attached respectively one to each disc A and B, pressure air being fed to the jack space # via an axial bore 4 in the drum shaft E. The concentric radially outer diaphragm space alpha is supplied with inflation air via a conduit 5 extending through the bore 4. Operation of the jack to move the discs A and B is controlled by the supply or exhaust of air to or from the space #. The two collars are movably sealed to each other by a ring seal d1 or by a flexible foldable diaphragm, the collars being shorter in this case. Fig. 6 shows an alternative arrangement wherein the jack is defined by a radially inner tubular circumferentially inextensible diaphragm K which is also sealed at its ends to the end discs A and B to define the jack space #. In this arrangement, a spring-loaded compressible buffer 14, 17, 21 is carried by the disc A and serves to set the limiting positions of the disc B for the shaping and removal respectively of the carcase. An adjustable outer stop 6 on the shaft E limits the building position, of the disc B. In an alternative arrangement Fig. 10, a collar 25 extending exteriorly of disc B slides over an adjustably fixed stop 26 on the shaft E and carries an abutment member 27 at its outer end. The space 28 defined by the disc B, collar 25 and stop 26 may be pressurized or evacuated to assist movement of the disc B between a building position abutting stop 26 and a removal position wherein abutment 27 contacts stop 26. In a further arrangement, the end discs A, B carry peripheral bead sealing flanges and the building diaphragm C defines the jack space, the shaping of the tyre being effected by direct inflation of the carcase outwardly of the diaphragm. Specification 952,624 is referred to.

Abstract: 1,217,203. Testing cigarettes. MOLINS MACHINE CO. Ltd. 30 Jan., 1969 [1 Feb., 1968], No. 5255/68. Heading A2C. A tester for cigarettes wherein a pressure differential is created radially across the cigarette to detect a leaky wrapping, comprises a circumferentially fluted carrier drum which co-operates with a circumferentially fluted closure drum, said flutes being axially disposed and carrying one cigarette each. The two drums rotate about parallel axes at the same peripheral speed and where the two drums cooperate, the flutes from each drum together momentarily define a chamber around the cigarette, terminated at or near the ends of the cigarette by seal portions partly defined by each drum, the cigarette being tested for leaks whilst in this chamber. An apparatus suitable for carrying out the testing process, is shown in Fig. 1 wherein a carrier drum 1 co-operates with closure drum 2, the latter being held by gravity in contact with drum 1, but being pivotally mounted on a hollow shaft 3. Suction for testing is applied from a fan via shaft 3 to a suction chamber in drum 2, the suction being applied via the port 50 to a cigarette contained in the chamber which is formed by the flutes of drums 1 and 2 momentarily co-operating. If the cigarette in the momentarily formed chamber has a leaky wrapper, a flow of air to the suction source via the leaky wrapper will be created, said flow being indicated by a pressure drop at the ends of the cigarette which pressure drop is detected by a transducer 40 (Fig. 2, not shown) which activates a mechanism to eject the faulty cigarette.

Filed: 1937-02-23
Abstract: 487,616. Toy aeroplanes. DUTTON, H. C. Feb. 23, 1937, No. 5342. [Class 4] A toy aeroplane is automatically controlled by means of a movable mass, which may be either liquid or solid, located in a tube or container adapted to tilt between fixed limits about a transverse axis and connected to the elevator and if desired to wing flaps. In one form a glass tube a closed at both ends is bent slightly at the centre to receive a small quantity of mercury b and is pivotally carried by a transverse axle a<2> to which are secured arms c and d connected to elevator and flap operating levers respectively. Rocking movement of tube a is restricted by stops e, el of which e<1> is adjustable, being carried by a frictionally locked lever e<2> having a handle e<5>. If the nose of the aeroplane tilts downwardly, tube a is also tilted by reason of the presence of stop e the mercury runs to the forward end of the tube and causes further tilting movement of the tube limited by stop e<1> thus producing stabilizing movement of flaps and elevators. The mercury is returned when the aeroplane nose tilts upwardly sufficiently to bring tube a substantially horizontal. A metal ball in a closed ended tube may be substituted for the mercury. Both stops may be adjustable.

Title: Process for the reforming treatment of motor fuels
IPC: C10G35/06
Filed: 1937-02-23
Abstract: Motor fuels of low anti-knock value, e.g. straight-run gasolines, are reformed by subjecting them at 400-750 DEG  C. for a contact time of less than 15 secs. to the action of catalysts comprising refractory base materials of relatively low catalytic activity which support minor additions of promoters of relatively high catalytic activity selected from compounds of the elements of the left-hand columns of Groups IV, V and VI of the Periodic Table, other than halogen compounds.  Refractory base materials specified comprise magnesium oxide, aluminium oxide, bauxite, bentonite clays, montmorillonite clays, kieselguhr, crushed firebrick, or silica, glauconite, acid-treated clays.  The oxides may be prepared by the calcination of suitable ores or minerals, e.g. magnesite, diaspore, bauxite, or by precipitation from salt solutions.  The promoters, which are used in amounts less than 10 per cent of the carrier, comprise oxides &c. of titanium, zirconium, cerium, vanadium, columbium, tantalum, chromium, molybdenum, and tungsten, and are applied to the carriers by precipitation from aqueous solutions or by moistening the carriers with solutions of the metallic compounds and then igniting to dryness.  The catalysts may be activated by pretreatment at elevated temperatures in air, steam, carbon dioxide, hydrogen, nitrogen.  In examples: (1) a catalyst comprising 94 per cent aluminium oxide, 4 per cent chromium sesquioxide and 2 per cent water is obtained by making a paste of activated alumina and chromic acid solution, evaporating to dryness, grinding and reducing the trioxide to the sesquioxide by treatment with hydrogen at 370 DEG  C.; vapours of a naphtha of 130-225 DEG  C. boiling range are passed through a vertical chamber containing the catalyst particles at 500 DEG  C. and atmospheric pressure for a contact time of 4 seconds, the octane number of the naphtha being increased from 40 to 70; the catalyst after 5 days' use is regenerated by oxidation in air; (2) a catalyst is obtained by adding 20 parts of ammonium molybdate in 50 parts concentrated aqueous ammonia to 250 parts alumina produced by calcining bauxite at 700 DEG  C., drying, and heating to 350 DEG  C. for eight hours followed by reduction in hydrogen at 500 DEG  C.; a naphtha of 140-225 DEG  C. boiling range and octane number 30 is passed over the catalyst at 500 DEG  C., and the octane number is thereby increased to 65; (3) a suitable catalyst is also prepared by dissolving ammonium metavanadate in hot water and adding thereto activated alumina.  Specifications 470,588 and 475,125 are referred to.
