Title: Apparatus for the continuous softening of feed water for steam boilers
IPC: C02F1/68
Filed: 1946-01-31
Abstract: 607,012. Softening water. KRUGER AKTIESELSKAPET. Jan. 31, 1946, No. 3140. Convention date. Jan. 30, 1945. [Class 46] Apparatus for softening water on board ship comprises a container divided into four compartments, the upper compartment a serving as a mixing chamber for raw water supplied through a pipe e, and precipitating agents, for example sodium hydroxide and sodium orthophosphate, supplied together with return boiled water, through a pipe q. The mixing chamber is also provided with a pipe f for steam supply and with a vent pipe h. The treated liquid is fed by a pipe i to the lowermost compartment d which contains vertical plates o adapted to prevent splashing, The plates become coated with precipitated calcium carbonate which acts to promote further precipitation. The liquid from compartment d flows up through a filter of wood-shavings in a compartment c, and into a compartment b provided with an outlet k to the feed-water tank. The filter is cleansed by reverse flow of liquid when an outlet valve p has been opened. In a modification the compartment a serves as a heating chamber only, the channels being mixed with the liquid in the compartment d.

IPC: F02D1/00
Filed: 1948-02-04
Abstract: 643,540. Fuel-injection pumps. C. A. V. Ltd. Feb. 4, 1948, No. 3235. [Class 7 (iii)] [Also in Group XXVIII] The output regulating member a of a fuel injection pump is combined with means for allowing an extra supply of fuel at starting which means comprise a contact piece f adapted to co-operate with an abutment b which is movable by a manually operable push button h from a position which determines the normal maximum fuel supply to the position shown which allows an extra supply of fuel, and is adapted to be held in the latter position against the action of spring d by a catch member j which is adapted to be released by the contact piece f to allow the abutment to return to its original position, the push button, if held down whilst the engine is running, having means to prevent the regulating member a from moving to its normal maximum fuel position. The contact piece f is adjustably connected to the regulating member and is adapted to enter a hole g for allowing the extra fuel supply whereupon the catch j is depressed and when the contact piece is moved out of the hole g after the engine has started, the abutment b moves upward and the stop position of the regulating member is determined by the outside surface of the abutment. If the button is pressed during running its shroud n envelopes the abutment and prevents the contact piece from engaging it. In other embodiments described the abutment member is slidable on a pivoted lever which is secured to the pump regulating member and adapted to be rocked thereby. The contact piece is adjustably mounted in the stationary pump casing and the push button if depressed during running obstructs the movement of the pivoted lever.

Title: Improvements in electromagnetic regulators
IPC: H02P9/22
Filed: 1939-02-01
Abstract: 524,580. Automatic regulators. NEWTON, F. Feb. 1, 1939, No. 3407. Drawings to Specification. [Class 38 (iv)] In a carbon pile regulator a lever, actuated by an electromagnet to relieve the compression applied to the pile by a spring, has its ratio varied as the magnet armature moves to compensate for the change in magnetic traction. The lever rolls upon or is provided with a curved surface, such as an ellipse. A circular curvature of suitable radius may provide correct compensation for change in magnet pull at three points, conditions elsewhere being sufficiently correct for practical purposes. To compensate for temperature effects the lever or the platen upon which it rolls may be a bimetallic structure so that the curvature may change with temperature, or a bimetallic element may vary the point of application of one of the forces acting on the lever.

Abstract: 547,894. Power plant; pumps. SULZER FRERES SOC. ANON. March 14, 1941, No. 3483. Convention date, March 29, 1940. [Class (ii)]  A main reversible engine 1 drives the propeller of a ship, aircraft, or vehicle through gearing 3, and an irreversible engine 2 assists the forward drive but is uncoupled by a clutch 7 for reverse driving. Each.engine is provided with two-stage' blowers 11, 12 having intercoolers 13 and driven by exhaust-actuated turbines 14. The blowers of the engine 2 may also be driven directly by this engine through the gearing shown, so as to be available when starting, the air from its blowers being also supplied to the main engine through a stop valve 15. The engine 2 may develop more power than the engine 1, in order to allow for the surplus power required for driving its blowers as well as assisting in the forward propulsion. The Specification as open to inspection under Sect. 91 also describes a plant in which the engine 2 only is fitted with a blower, which is driven directly from its engine and not by an exhaust-actuated turbine, the blower serving to supply both engines. This subject-matter does not appear in the Specification as accepted.

Abstract: 539,037. Skiving machines. BRITISH UNITED SHOE MACHINERY CO., Ltd. (United Shoe Machinery Corporation). Feb. 24, 1940, No. 3494. [Class 31 (i)] Cylinder-knife skiving machines of the kind described in Specifications 278,769 and 318,290, [both in Class 31 (i)], have the work-supporting surface inclined upwardly and away from the operator's station, a detachable head carrying the driven pressure roll, so that an idle presser roll or a presser foot may be readily substituted, and a grinding wheel angularly movable about an axis parallel to that of the knife to bring the wheel into and out of operative position. From the operator's position on the right of Fig. 3 the work supporting surface slopes upwardly and is apertured for the projection of the knife 17 and the lower feed roll 129. This roll is driven by a shaft 149 and is carried by a member 189 rigid with a shaft 193 engaging an inclined bore in a yoke 157 pivoted on a shaft 159. The yoke is urged anti-clockwise by a spring 175, an eccentric stud 179 determining the normal position of the feed-roll, and the member 189 is urged upwardly about the shaft 193 by a spring 195. The roll may be changed after removing a screw retaining the shaft 193 in its bearing. A driven presser roll is secured to a shaft 265 mounted in bearings on a holder 253 pivoted at 255 to a member urged upwardly by a spring 245 to a limit determined by a stop 247. A screw stop 259 and spring 257 determine the angle of the axis 265. This mechanism is carried by a head 239 removably carried by the upper surface of the work support, and housing a shaft driven by skew gearing from a shaft in the base of the machine. The knife has an internal chip deflector 61, adjustably carried by a screwed stem 63 locked by a screw 65. A grinding wheel 67 for the knife is pivoted at 85 and swung to and from operative position by a screwed stem 103 having a head 105. The wheel is driven by a belt when the knife is to be ground. After grinding, the edge of the knife may be adjusted to its former plane by turning a sleeve carrying a pinion meshing with a rack on the knife carrier. A plate 293 is rigid with a rod 297 engaging a slot in the knife carrier to cover the gap which would otherwise exist behind the knife after adjustment.
