[Class 110 (i).] A self priming centrifugal pump has an impeller 5 rotating in a chamber, the sides 1, 3 of which have channels 9 extending from the vicinity of the suction ports 6 to the vicinity of the discharge ports 7. The impeller has cast blades 12 with a peripheral shroud 14 ; the front and rear walls of the pockets 8 formed by the blades are concentric curves at their inner ends, and parallel at their outer ends. The suction ports 6 in the wall 1 may be triangular and are placed in the wall 1 near the hub while the discharge ports 7 are near the periphery in the wall 3. The ends 10 of the channels 9 are sloped to merge into the chamber 1, and the maximum depths of the channel are situated opposite the forward ends of the suction ports. The bottoms of the sloping sections may be roughened. Similar sloping sections are provided at the discharge ends 11 of the channels. When the impeller is rotated, the water retained in the pump or specially introduced for starting is thrown to the shroud 14, and air from the suction ports is trapped in the impeller and passages 9. As this air passes out to the delivery ports its volume is diminished by the decreasing depth of the ends 11 of the channels, and the air is exhausted from the suction pipe until normal pumping is initiated. In a modification a pump of the type described is combined with an ordinary centrifugal pump. Specification 388,052 is referred to.

Title: Improvements in indicating, recording, regulating and the like apparatus
Filed: 1922-11-03
Abstract: 211,920. Waller, P. H. Nov. 3, 1922. Counting-apparatus.-In indicating, recording, regulating, and like apparatus operated by an impact or contact device capable of oscillating, such as printing-machinery of the flat-bed type, an electrical system is interposed between the impact device and the indicating or like component so as to render the oscillations, after the first, ineffective on the indicator or the like. Fig. 1 shows an oscillating contact lever 1 which is movable about its pivot to cause the contact arms 3, 4 to close the contacts 15, 25 according to the direction of movement. Restoration of the contact arms 3, 4 by the springs 5, 6 is delayed by the rotating-mechanisms 12, 13. The arms 3, 4 respectively control contacts in the circuits to the coils 22, 30 through contacts 19, 28 which are opened when the other coil is energized. The cores of the two coils control the step-by-step rotation of counting-mechanisms on a shaft 38, through one-way ratchets, and their return movement is retarded by mechanisms 33, 35. Thus, if the lever 1 swings back so far as to cause the closing of the contacts 25, the circuit to the coil 30 is open at the contact 28 and the core of the coil 30 is not moved. A roller detent entering a notch 44 is the counterweighted end of the lever 1 serves to hold the lever in normal position.

Title: Improvements in or relating to the production of alloy-steel forgings
Inventor: JONES FREDERICK WILSON
IPC: C21D9/08
Filed: 1961-08-24
Abstract: Brittle fracture is reduced in an alloy steel forging which is to be submitted to centrifugal stress and having an axial bore by subjecting the bore surface to controlled liquid quenching, e.g. by spraying water on to the surface of the bore, to a temperature below the martensitic transformation temperature under conditions such that the average temperature of the forging does not fall below 250 DEG C. throughout the quenching, thereby producing a low temperature bainitic structure adjacent to the martensitic structure of the bore thus ensuring that highly stressed parts of the forging have low impact transition temperatures.  The forging may also be quenched externally.  The hardening may be followed by tempering to reduce residual stresses, e.g. to no more than 2 tons p.s.i.  Examples are given of alternator rotors and turbine wheel forgings made from 3% Cr-Mo and 2 1/2 % Ni-Cr-Mo steels.
