The circuit of the coils a is made and broken at contacts g, g', which are operated by a sliding rod e connected to the arm b<4> by a flat spring f. The end of the arm b<4> works in an adjustable collar on a sliding rod n<1> which terminates in an adjustable air dash-pot n. Quick-action mechanism for the rod e comprises two bell-crank levers h pivoted at either side of the arm b<4>, each lever h having at one end a knife-edge pin i co-operating with a collar k on the rod e and at the other end a hole through which passes a rod m pivoted to the arm b<4> and carrying stop collars l. When the armature b is attracted, the spring f is flexed but the rod e cannot move until the arm b<4> moves the collar l on the rod m against the lever h, releasing the pin i from the left-hand collar k and thereby allowing the lever e to move over quickly under the influence of the flexed spring f, breaking the energizing-circuit of the coils a at contacts g, g'. A similar action ensues in the return movement of the armature, the speed of which is controlled by the dash-pot n, the energizing-circuit being suddenlv re-made at or about the end of the armature stroke, which is limited by stops a<1>, a<2>. Contacts for controlled circuits may be attached to the rod n<1> as at o, p or may be attached to the rod e.

Title: Regulating device for piston pumps with shaft drive and variable length of stroke
IPC: F04B1/06
Filed: 1920-06-30
Abstract: 145,642. Krupp Akt.-Ges., F. June 26, 1917, [Convention date]. Stroke, varying.-In a piston pump with shaft drive and variable length of stroke, a stroke-controlling piston H is open on one side to the delivery pressure through a pipe a<4> and on the other side to the pressure of a pressure reservoir through a pipe J. An accumulator M with a piston K is open at one end to the pump delivery through a pipe m<1> and at the other end to the pressure reservoir through a pipe m<2>. The piston H is connected by links F, E, D to a sleeve C on the pump shaft controlling the length of stroke. The sizes of the pistons K and H are such that the ratio of the areas of the two sides of the piston K is greater than the ratio of the areas of the two sides of the piston H. When the delivery pressure rises, the piston K descends until a collar k<2> on its rod engages a spring-pressed plate N. When the pressure rises further, the piston K descends again, the spring P is compressed, and the pressure on the right side of the piston H is sufficient to move the motor to the left and shorten the pump stroke. The normal position of the piston H corresponds to the maximum stroke of the pump.

Title: Improvements in process and apparatus for precipitating calcium saccharate from liquids containing sugar and separating excess lime therefrom
IPC: C13B35/04
Filed: 1924-07-30
Abstract: 233,936. Steffen, C., and Steffen, C. July 30, 1924. Refining sugar.-In extracting sugar from saccharine liquids by precipitating it as calcium. saccharate by means of lime which is added to the solution as quicklime, the undissolved lime which has not entered into the reaction is separated from the lighter calcium saccharate by settling, centrifugation, &c. before the liquid containing the saccharate is passed to the filterpresses. The lime thus separated is used for precipitating a further quantity of sugar, and it is stated that if the separator is keep cool, about 15‹ C., unslaked lime entangled in the slaked lime remains unslaked and the mixture is more efficient in precipitating the saccharate. Apparatus for the purposes comprises a lime-supplying device M, a settling chamber S, and a cooler K of ordinary type. Between the cooler K and the lime-supplying device M is arranged a settling chamber A provided with a cooling jacket B. The separated lime can be passed by a pipe d to the chamber S to treat a new lot of solution.
