Abstract: 675,010. Rail-truck movers. BIRMINGHAM SMALL ARMS CO., Ltd., and FLETCHER, J. March 1, 1951 [Dec. 2, 1949], No. 30937/49. Class 79(i) A truck mover has lower and upper lifting heads for engaging the truck, each movable by the jack in a path whose direction approximates to the direction of the resultant force exerted by the truck, the upper head being movable rearwardly when the lower head is in use. With this arrangement, the effective range of the jack on the truck mover is doubled. Fig. 1 shows the front part of the truck mover 1 mounted on driven wheels 4 and 5, with the lower lifting head 6 in operative position and the upper lifting head 6 folded back. Fig 3 shows the upper lifting head 6 in working position. As shown in Fig. 1, the ram of the hydraulic jack 8, supported on trunions 9, is pivotally connected to a webbed lever 13 which is pivoted at its forward end 14 and carries the lower lifting head 7 at its rear end. The range of movement is between the positions shown in full and in dotted lines. If a higher range is required the upper lifting head 6 and its associated radius arm 16, arm 19 and link 22 are freed from the spring clip 25 and swung about pivot 17 into the position shown in Fig. 3, wherein the slotted ends of the pair of struts 18 are engaged on pivot 14 and the slotted ends of links 22 are engaged on the pivot 15 which mounts lower lifting head 7 on its webber lever 13. A full stroke of the hydraulic ram then results in movement of the upper lifting head 6 from the position shown in full to that shown in dotted. The mean path of the lower and upper lifting heads is on the line AB which is arranged to be parallel to the line of the resultant force exerted by the truck when it is moved. Specifications 655,694, 655,704 and 668,174 are referred to.

Title: Improvements in or relating to hydraulic pumping apparatus
IPC: F04B9/117
Filed: 1939-11-29
Abstract: 535,119. Reciprocating pumps. STEVENS, A. H. (Jackson Co., B.). Nov. 29, 1939, No. 31070. [Class 102 (i)] [Also in Group XXIX] Hydraulic pumping apparatus comprises a diaphragm, plunger, floating piston, or like movable partition dividing each of a number of cylinders into motive-liquid and pulp-liquid compartments, valve means for intermittently admitting motive-liquid under pressure to said motive-liquid compartments to move the partitions in one direction, and valve means for admitting and discharging pump-liquid to and from the pump-liquid compartments, the motiveliquid valve means being actuated solely by motive-liquid independently of the movements of the partitions. The partitions may be moved in the opposite direction by exhausting the spent motive-liquid from the motive-liquid compartments and/or by pump-liquid at relatively low pressure supplied to the pumpliquid compartments between intervals of admission of motive-liquid. For the motiveliquid, a steady stream of pressure water is supplied preferably by means of a centrifugal pump. Fig. 2 shows a section through a pump with three horizontal parallel cylinders 2 each containing a radially expansible rubber or like elastic diaphragm 20 with spacer bars 18, and each having a pump-liquid suction and discharge chamber 5, inlet and discharge valves 6, 7, and common suction and discharge headers 8, 9. The chamber 5 communicates with the cylinder space 23 by means of passages 24, and motive-liquid is supplied to the open end 21 of the diaphragm assembly by means of a reciprocating valve 33 and a passage 38. The valve 33 is reciprocated by motive-liquid supplied to the upper side of a piston 52, and the phase relationship between the three valves is maintained by connecting them by rods 47 to a common crankshaft 45. This motiveliquid is supplied through a branch conduit 54 leading to a chamber containing a rotary distributing valve secured to the crankshaft 45 and serving the pistons 52 in sequence. The volume of motive-liquid flowing to the valve motor is regulated according to the rate of flow of motive-liquid to the diaphragm by means of a venturi regulator 65 with a throttle valve 62 leading to the branch pipe 54. Fig. 7 shows the invention applied to a pump having three radial cylinders such as 71 each containing an axially expansible "Sylphon" bellows 74 with a rigid end plate 75 at its movable end, a reciprocating valve 32<SP>1</SP> operated by a piston 51<SP>1</SP>, and a rotary distribution valve 56<SP>1</SP>. Fig. 9 shows the invention applied to a pump having three vertical cylinders such as 101 each containing an axially expansible " Sylphon " bellows 125 secured to the motive-liquid ends of the cylinders, the motive-liquid being admitted by a rotary distributing valve 129 rotated by a small hydraulic radial-piston motor 135. Fig. 15 shows a pump similar to that shown in Fig. 2, but using a floating piston 215.

Title: The incorporation of inorganic materials into fuel oils
Inventor: GARNER PHILIP JAMES
IPC: C10L1/12
Filed: 1953-11-16
Abstract: A dispersion of a substantially dry solid inorganic material in a high ash residual fuel oil (i.e. a fuel oil having an ash content of at least 0.005 per cent by weight and a viscosity of at least 35 seconds Redwood I at 100 DEG F. and consisting of or containing a residual petroleum oil) is prepared by mixing the inorganic material with the fuel oil in the presence of an oil-soluble surface-active agent and mechanically working the mixture until it is substantially homogenous.  The inorganic material may be naturally-occurring or synthetic, for example silicon, ferrosilicon, inorganic oxides, hydroxides or carbides, metallic carbonates, silicates, sulphides, aluminates, sulphates, silicides or zeolites, kieselguhr, talc, asbestine, bentonite, kaolinite or montmorillonite, or mixtures of these.  The surface-active agent may be cationic, ionic or non-ionic, e.g. high molecular weight amines especially quaternary ammonium compounds, alkylamines, alkylated heterocyclic bases, partial amides of alkylene diamines, complex polyamines, free carboxylic and sulphonic acids and salts thereof, non-ionic hydroxy compounds, phosphorus-containing compounds and polyoxyalkylated product of some of these materials; numerous examples of each type are given.  The high ash residual fuel oil may consist of a mixture of residual petroleum oil with other liquid fuels such as distilled or cracked hydrocarbon fuel oils.  On combustion, the high ash residual fuel oil may form an ash containing a major proportion of vanadium and/or sodium compounds.  Fuel oil concentrates containing 1-70 per cent of the inorganic material may be prepared and subsequently diluted with additional fuel oil to obtain fuels for use in gas turbines or furnaces.  In the examples, fuel oil compositions are prepared from high ash petroleum residual fuel oil and (i) silica, asbestine or magnesium carbonate using aluminium stearate as the surface-active agent or (ii) asbestine using sodium sulpho di-iso-octyl succinate as the surface-active agent.  Specification 745,012 is referred to.

Patent GB-318568-A (GB)
Abstract: 318,568. National Cash Register Co., Ltd., (National Cash Register Co.). June 6, 1928. Printing totals. - In a cash register wherein a total lever 30 is adjusted from the add position to one of a number of total-taking positions as a preliminary to a total-taking operation, mechanism is provided for automatically restoring the lever to the add position at the end of a total-taking operation when this has taken place with the lever in a particular total-taking position. The lever is provided with a lug 45 which, when the lever is shifted one step below the add position, stands in the path of one of a pair of rollers 46 carried by a flanged sleeve 47. Coaxial with this sleeve and operative upon it by a one-way ratchet connection 61 is a. spring-influenced gear wheel 56 engaged by a toothed sector 55 from which depends a hook 52 controlled by a link 90. A lever 48 is depressed and released once per cycle by means of a cam 50 and has a stud 51 co-operating with the hook. When the total lever is shifted to the first position below adding as shown dotted in Fig. 1, and a totaltaking operation is initiated, the usual lever 93 shifts the link 90 and the hook 52 to the left during the time the lever 48 is in its displaced position. When the lever 48 returns at the end of the first cycle therefore, the stud 51 engages the hook so that in the second cycle the hook is drawn down by the lever 48 against the action of a spring 75 and the sector rotates the gear-wheel 56 clockwise. This movement has no effect on the sleeve 47 which remains locked by a detent 59 until released by a pin 80 on the sector. In the return of the lever 48 to normal position towards the end of the second cycle, the sector, gearwheel and sleeve tend to restore the total-lever through the medium of the lug 45 but are prevented on account of this lever being locked due to the construction of the two-cycle control mechanism. When this mechanism finally reaches home position the total lever is free and the spring 75 actuates the gear-wheel and the sleeve to return the lever. If the lever is adjusted to any other total-taking position the lug 45 will be beyond the path of the rollers 46 so that the restoring- mechanism will be without effect. Specifications 8119/15, 191,350, and 191,351 are referred to.

Void [Abridged as open to inspection under Sect. 91 of the Acts, July 28, 1933]. [Class 55 (ii).] To remove dust and metal vapours from gas it is passed down tubes 4 in a chimney 1 and sprayed upwardly from nozzles 10 preferably with hot water and from supplementary nozzles 11 to obtain a desired dew-point controlled by a thermostat 16 and expanded in a chamber 6. Moisture is condensed by passing the gas up over staggered horizontal rows of water-cooled tubes 24, the water flowing as shown through headers 26. Cold water is sprayed intermittently from nozzles 29 over the tubes, and water and gas are deflected inwardly by downwardly inclined flanges on the walls between the tubes. Water from the cooling tubes is warm and is passed by a pump 39 to the nozzles 10, which may be of ceramic material with bronze tips whereby the water sprayed becomes electrically charged. The gas passes off at 21 and sludge falls into a collector 7 with a syphonic outlet 7<a>.
