Title: Improvements in or relating to water treating apparatus and methods
IPC: C02F1/52
Filed: 1944-01-07
Abstract: 578,382. Treating water. INFILCO, Inc. Jan. 7, 1944, No. 338. Convention date, Jan. 7, 1943. [Class 46] In a water softening or clarification process the water is treated in contact with a large body of slurry accumulated from previous treatment and the water is circulated between the lower body of slurry and an upper body of clarified water, the separation of the clear water at the interface being promoted by subdividing the flow into a number of narrow streams by sloping surfaces which act as receiving surfaces for the solids separating, these solids passing thence to the main body of slurry. Raw water and reagent respectively enter a conical tank by pipes 77, 78 and under the influence of an impeller 25 pass to and rise upwardly in a reaction cylinder 50 mixed with slurry drawn from the lower portion of the tank. The precipitate and flocs arising from the reactions with the reagent are agglomerated on the slurry particles; agitator arms 29 facilitate this action. From the top of the reaction chamber 50, which is closed at the top, the liquid passes by radial conduits 69 which are slotted at the sides to provide openings 73 for the liquid to pass laterally into the narrow spaces formed by a nest of sloping baffle rings 74 on the surfaces of which the solids settle to pass thence into the main body of slurry in the tank, while the clear water rises up into the clarified-water space 51 and eventually passes over a weir 14 to a launder 15 and service line 16. Sludge concentrated in a pocket or chamber 60 is drawn off by a pipe 62. The circulation flow is greater than the rate of raw water admittance. A modification is described in which the narrow streams are formed by radially-arranged sloping plates, Figs. 1 and 2 (not shown), additional sloping plates being inserted towards the outer periphery of the tank. Specification 578,383 is referred to.

Title: A circular saw for cutting the jointing faces of segments of circular patterns
Inventor: KLASTERSKY VACLAV
IPC: B27B5/20
Filed: 1955-01-05
Abstract: 777,622. Sawing; mitering; tools for setting out work. YVZKUMNY USTAV TVARECICH STROJU A TECHNOLOGIE TVARENI. Jan. 5, 1955, No. 344/55. Classes 61 and 145 A jig for positioning annular segments of a circular pattern in a sawing machine so that their ends can be trimmed to the required angle and chord dimension comprises an arm 18 pivoted at 17 in the plane of the saw 15 and a bar 21 which is supported by the arm and carries a pair of adjustable supports 23, 24 for engaging the outer arc of a segment and an adjustable depressible abutment 32 for engaging one end of the segment. To set the jig, the arm 17 is rotated until the front wall of the bar 21 registers with the required number on a scale 20 graduated with numbers corresponding to the circular pitch or number of segments required for a full circle and is locked in position by a clamp screw 22 fitting in an arcuate groove in an extension of the bar. The support 23, which is carried by a bar 26 adjustable along the bar 21 by a screw 25, is then set so that a pointer 27 coincides with the required number on a circular pitch scale 27<SP>1</SP> and the support 24, which is carried by a slide 28 clamped in position on the rod 21 by a screw 35, is displaced until a vernier 34 indicates the required calculated chord length L on an inch or millimetre scale on the bar 26. Finally, by rotating a screw 31, the depressible abutment 32 is adjusted on the slide to a position in which a pointer 33 coincides with the required number on a circular pitch scale 33<SP>1</SP>. A blank which is oversize chordwise is then placed against the supports 23, 24 so that there is enough overlap at one end for the saw to cut a clean surface and so that the abutment 32 is depressed by the other end of the segment. While the segment is held in place by a clamp 36, the saw 15, which is slidable on an arm 12 vertically adjustable on a column 8, is moved along the arm 12 by hand to make the first cut, the direction of rotation of the saw holding the segment down on the table. The saw is then returned to its initial position, the segment is reversed so that its cut surface bears against the abutment 32 and the other end of the segment is cut to give the required chordwise dimension of the segment.

Title: Hydraulic valve operating and reversing apparatus for internal combustion engines
Inventor: GROSCHEL ERNEST RALPH
IPC: F01L9/11
Filed: 1963-01-04
Abstract: 1,010,703. Reversing; valve gear. RUSTON & HORNSBY Ltd. Nov. 25, 1963 [Jan. 4, 1963], No. 443/63. Headings FIB and F1K. In hydraulic poppet valve operating and reversing apparatus for reversible internalcombustion reciprocating piston engines, the poppet valve operation for forward or reverse engine rotation is selected by the setting of a changeover valve 26 situated in a pipeline connecting a poppet valve actuating ram 38 with either of two cam operated plungers 15, 20 per engine cylinder, one for forward and one for reverse engine rotation, the pipeline. being connected with means for circulating hydraulic fluid through the pipeline whereby the pipeline may be primed with the hydraulic fluid one of the plungers depending on the setting of the change-over valve being arranged during each cycle in accordance with the cyclic rotation of a cam 12 on the engine camshaft to isolate and pressurise a column of fluid between the plunger itself and the valve actuating ram to open the poppet valve 31, 32, the poppet valve being arranged to close as the fluid column pressure is relieved when in accordance with further cam rotation the plunger moves to re-establish circulatory connection between the pipeline and the circulating means, the ensuing circulation substantially scavenging the formerly isolated fluid at each cycle. The invention is described as applied to a three cylinder two stroke cycle direct reversing engine but may be applied to four stroke cycle spark ignition or diesel engines. It may be applied to inlet as well as exhaust valves and to other than overhead valves. A camshaft with two cams per cylinder may be used one for forward and one for reverse running. The changeover valve may be manually or automatically operated.

Title: High-voltage power circuit-breaker with a flowing quenching medium
IPC: H01H33/56
Filed: 1965-01-06
Abstract: 1,087,701. Fluid-blast circuit-breakers. LICENTIA PATENT - VERWALTUNGS - G.m.b.H. Jan. 6, 1965 [Jan. 6, 1964], No. 548/65. Heading H2B. In a high-voltage fluid-blast circuit-breaker the pressure fluid is supplied through a blast valve 3 which is at high potential and is controlled by a control device 14, 13 at earth potential and by a device responsive to excess currents and arranged in the extinguishing head of the circuit-breaker. Fig. 1 illustrates a multibreak gas-blast circuit-breaker in which each interrupting unit 1, I<SP>1</SP>, 1<SP>11</SP> has an electromagnetic valve 5 which opens when short-circuit currents occur, and the leading unit 1 has a further electromagnetic valve 2 which opens when a moderate excess current condition occurs. These valves control the supply of compressed gas to pneumatic motors 4 operating the valves 3 and to pneumatic motors 6 to release toggles 7 so that the valves 3 can open without retardation when operated by the motors 4 under short-circuit conditions. The toggles 7 connect the valves 3 to hydraulic motors 8 which may be driven by an hydraulic pump 13, 14 to actuate the valves 3 to apply opening blasts to the interrupting units or to apply compressed gas to the units to close their contacts. Under moderate overload conditions only the valve 2 is operated by the current so that the blast valve 3 of the leading unit 1 is opened without the toggle 7 being released. The resulting movement of the piston of the motor 8 establishes a pressure across a throttling device 15 to operate a control device 16 which then renders the pump 13, 14 effective to operate all the motors 8 to open all the blast valves. An interrupting unit of the double extinguishing head type is described and illustrated in Figs. 2 and 3 (not shown).

Title: Improvements in or relating to gear-boxes
IPC: F16H3/08
Filed: 1965-01-06
Abstract: 1,094,811. Change speed gear. A. E. C. Ltd., and E. J. RIDDLE. Jan. 6, 1965, No. 620/65. Heading F2D. A change speed gear for vehicles providing ten or twelve forward ratios and reverse comprises a two-speed planet or countershaft gear in series with a five or six-ratio main gear having aligned input and output shafts 13, 15 which may be clutched together at 20 for direct-drive and two countershafts 16, 17 driven at different speeds from the input shaft 13 through gear pairs 25, 26; 28, 29. Both countershafts carry identical gears 30, 31 meshing pinions 34, 35 fast with the output shaft 15 and the gears 30, 31 are selectively clutched at 32 to their countershafts to provide four reduced ratios. A gear 40 which meshes a pinion 42 on the output shaft 15 may be clutched at 41 to the countershaft 16 for overdrive. Reverse is obtained by sliding a pinion 43 on the countershaft 17 into mesh with a pinion 46 on an idler shaft 18 which carries a pinion 47 in constant mesh with the output pinion 35. The ratios may be in geometric progression. In Fig. 4 (not shown), the axial length of the gear is reduced by arranging the clutch operating sleeve 20 on the other side of the gear 35, the clutch comprising pins which pass through holes in the gear 35 and engage recesses in the gear 25. In this embodiment the reverse pinion is fixed on the countershaft 17 and the pinion on the idler shaft is axially slidable. In Figs. 5-7 (not shown) the overdrive gear pinion 40 is omitted and reverse is obtained by clutching a gear in permanent mesh with an output gear to the idler shaft, the direct-drive shift fork being extended to oparate this clutch. A power-takeoff may be taken from one of the countershafts.
