Abstract: 966,946. Hydraulic driving gear; controlling vehicles; adjusting vehicle height. L. A. MORTIER. March 16, 1962 [March 20, 1961], No. 10168/62. Headings B7D and B7H. [Also in Division B8] A self-propelled truck for lifting and rotating cable reels (see Division B8) is propelled by a single driving and steering wheel 37 which is driven and steered by rotary hydraulic motors 62, 63 respectively supplied with fluid from pumps driven by an I.C. engine 39. The wheel 37 is supported from a platform 38 which comprises plates 64, 65 secured to an annular block 67 supported in bearings 68, 69 on the crossmember 36 of the chassis and which is rotated about the axis 73 by an endless chain 74 clamped to the block 67 and engaging a sprocket 75, Fig. 3, driven through reduction gear 78 by the motor 63. The output shaft 94, Fig. 8, of the drive motor 62 drives a shaft 90, through a torque limiter 93, supported in roller bearings 89 in a housing 88 secured to the plate 64. The shaft 90 supports a bevel pinion 91 which meshes with a bevel pinion 91 1  secured to shaft 96 which drives, through an epicyclic gear train 97, the wheel hub 108, which forms a cover for the reduction gear. A control device 122, Fig. 19 (not shown), and Fig. 3, is provided with a single lever for controlling the starting, forward or reverse movement and stopping of the truck by controlling fluid distributers for forward or reverse movement, for the steering, and braking means are actuated to stop the truck when the lever is released. The truck may be driven at either of two speeds depending upon whether one pump 44, Fig. 1, or two pumps 43, 44 are connected to the hydraulic motor 62. The front wheels 5 of the truck, Fig. 1, are each rotatable on an axle 11 secured between a pair of arms 13 which are pivotally mounted on an axle 16 mounted on the chassis side member 3. The chassis is raised with respect to the wheels 5 by extension of hydraulic rams 32 each pivoted between a bracket 35 on the chassis and a lever 25 which is provided with a tyreengaging shoe 29 and which is pivotally connected to a crank 21 rotatably mounted on the axle 16 and secured to the arms 13. A spring 27 is connected between the crank 21 and lever 25. The rams are individually operable to level the chassis or to raise or lower the end of the chassis.

Title: Improvements in or relating to the recovery of ammonia from gases containing it and for the recovery of iron from waste pickle liquor
IPC: C01C1/12
Filed: 1947-04-18
Abstract: The process for recovering ammonia, as ammonium sulphate, from gases, such as coke oven gas, containing ammonia and hydrogen sulphide, and for recovering iron values from pickle liquor containing free sulphuric acid and ferrous sulphate, according to the parent Specification, in which a feed liquor containing ammonium sulphate and the pickle liquor is contacted with the gas to precipitate the major portion of the iron (partly as ammonium ferroferrocyanide) and to form ammonium sulphate in solution which is subsequently separated from the precipitate, is improved by removing the residual ammonia in the gas by contact with an aqueous solution of sulphuric acid.  In one embodiment (Fig. 1, not shown) the ammonium sulphate solution, resulting from the absorption of residual ammonia in a scrubbing operation, is passed to a crystallizing unit (similar to that described in Specification 559,360) the solution from which is pumped to an evaporative cooling chamber, and the resulting supersaturated solution is returned to the crystallizer, from the bottom of which large crystals of ammonium sulphate are removed, and from the top a solution of ammonium sulphate is recycled, with or without additional sulphuric acid and water, to the absorption stage of the residual ammonia.  In another embodiment (Fig. 2 not shown) an ammonium sulphate saturator is used instead of the scrubber operation in conjunction with the crystallizer.

Title: Stud tensioner having self-aligning connector
IPC: B25B29/02
Filed: 1962-03-19
Abstract: 948,555. Bolts-tensioning. DIAMOND POWER SPECIALTY CORPORATION. March 19, 1962 [May 8, 1961], No. 10435/62. Heading F2H. A stud tensioner 11 comprises a pedestal 17, supporting a cylinder 18 to which it is attached by flexible links 31, the cylinder housing a piston 19. The lower end of the piston forms a hollow rod 21 which is externally threaded and to which a drawbar 35 is engaged. The lower end of the drawbar has an inwardly directed shoulder 36 of slightly larger diameter than the stud thread. The upper surface 39 of the shoulder is of frusto-conical shape for engagement with a nut 56 of a self aligning connector 54. The nut 56 is universally connected to telescopic tube 55 within guide sleeve 44 so as to permit location of said connector over the stud to be tensioned. The tensioning operation is effected by positioning the tensioner over the stud, alignment between pedestal and cylinder being permitted by spherical bearing members 24, 25. The nut 56 subsequently is positioned over the stud, tube 55 being telescoped within sleeve 44 and engagement between stud and nut produced by rotation of the connector assembly with gear 45 of the bevel gear assembly at the top of the tensioner until the nut contacts the surface 39 of the shoulder 36. Hydraulic pressure may then be applied to the underside of the piston 19 and the force then exerted is transmitted to the stud via the drawbar through contact with the nut at the surface 39. In another embodiment the nut is formed in four segments, threaded internally and externally each segment engaging the drawbar on an internal convergent conical taper thread so that rotation of the whole connector assembly screws the nut segments down the taper of the drawbar and into threaded engagement with the stud.

[Also in Division H3] In a device for detecting changes in the rate of flow of a fluid (e.g. ventilating air in a mine) by virtue of the consequent changes in the cooling effect of the flow, an electric heating coil 21 exposed to the fluid flow is connected in an A. C. bridge circuit 47 with a temperature-compensating coil 22 which is similar but shielded from the fluid flow so as to be affected only by its temperature, the bridge being set by a slider 46 to be balanced at a chosen rate of flow; the phase-sense of any output from the bridge, relative to the A. C. supply at terminals 27, is indicative of the sense of the change in fluid flow rate from the chosen value. A transistor 51 acts as a phase-sensitive rectifier so that an amplifier 57 produces an output to energize a relay 64 only when the rate of flow is greater than or equal to the chosen value, the relay 64 being de-energized to light warning lamps 17 and actuate a control circuit 68 when the rate of flow falls below the chosen value.
