Title: Improvements in hydraulic pump and motor systems
IPC: F15B9/10
Filed: 1945-02-07
Abstract: 592,200. Hydraulic presses. NORMAN, R. M. Feb. 7, 1945, No. 3093. Convention date, Feb. 7, 1944. [Class 69 (ii)] In a hydraulic pump and motor system, the servomotor 21 controlling a reversible variable delivery pump 14 is connected to that, 45, controlling a one way variable delivery pump 15. As applied to a press the reversible pump 14 extracts liquid from one end of the ram cylinder 10 and discharges it to the other, while the other pump discharges from a reservoir into the upper end of the ram cylinder only. Hence the pumps work in combination on the down stroke, the approach portion of which may be assisted by liquid entering through the surge valve 13, while only the reversible pump effects retraction of the ram. A pilot pump 22 supplies liquid for actuation of servomotor 21 which is connected at 44 to the servomotor 45 of pump 15, and at 26 to exhaust. The servomotor piston 51 has large and small portions 54 55, supply of actuating liquid being controlled by a central valve 62 operated by a solenoid 29 to commence the down-stroke. The valve is then moved to the right and connects the left side of piston 51 and also servomotor 45 to pressure thereby starting both pumps. To effect retraction of the press the solenoid. is deenergizedand a spring 67 reverses valve 62 whereby the left side of piston 51 and servomotor 45 are connected to exhaust via passages 65 and 26. Thus pump 14 is reversed and pump 15 stops. At the end of the up-stroke the control valve 62 is brought to neutral position by a tappet on the press and the pump 14 stops. Specification 535,625 is referred to.

Title: Ultrasonic neutron dosimeter
IPC: G01T3/00
Filed: 1960-01-29
Abstract: 912,644. Ultrasonic inspection devices. UNITED STATES ATOMIC ENERGY COMMISSION. Jan. 29, 1960 [Feb. 27, 1959], No. 3273/60. Class 40 (7). [Also in Group XL (a)] Neutron dosage is measured by establishing ultrasonic wave pulses in a medium responsive to the neutron flux and remotely indicating an ultrasonic wave transmission characteristic in the medium. Continuous monitoring of a nuclear reactor in a vehicle is thereby provided. It is stated that the recoil particles in the medium, produced by the capture of thermal neutrons, disrupt the normal lattice structure of the atoms and cause minute mechanical changes which are detected by their effects on ultrasonic wave pulses. In the embodiment a borosilicate glass cylinder 16 and a piezo-electric transducer 52 are coupled by bonding cement or a liquid and are mounted in aluminium container 50; the glass cylinder may be embedded in glass wool. Generator 10 is triggered by oscilloscope 24 to produce pulses of 1 to 4 microseconds duration on a frequency in the range 5 to 200 mc/s. and at a repetition rate of 300 per second. The reverberations between walls 31, 32 of the glass cylinder are displayed on the oscilloscope which is calibrated by a crystal-controlled time delay; the velocity of the waves in the glass is thus obtained. Wave attenuation is found by introducing an auxiliary pulse via calibrated attenuator 30. Calibration of an apparatus is discussed, Figs. 4 and 5 (neither shown). The borosilicate glass may be replaced by a lithiumcontaining glass or lithium fluoride.

Filed: 1929-02-04
Abstract: 327,500. English Electric Co., Ltd., and Donnelly, W. Feb. 4, 1929. Exciting.-A variable-speed multipolar generator with a two-circuit armature winding for battery-charging, as in train-lighting or petrol or Diesel-electric sets, has a shunt winding only on some of the poles adapted to give battery terminal voltage at a low speed and a reversed series winding only on the remainder, adapted when carrying the charging current to cancel a part of the shunt flux and cause the machine to give full charging current at maximum speed. Satisfactory charging over a large speed range is thereby obtained. In the four-pole machine shown, three poles have normal shunt coils 1 and the remaining one a series coil 2 carrying the charging current and opposing magnetically the pole 4. If it be desired that charging shall occur from, say, half to full engine speed the shunt coils are designed to give full battery terminal voltage at half speed, at which speed the generator floats. At full speed, only two of the shunt poles are effective, but although the effective flux of the machine is lowered, the increase in speed gives an increase of about 30 per cent in the voltage, which is sufficient for full changing rate on the fully charged battery. With a larger number of poles, a greater range may be obtained, for example by winding two poles with a reversed series winding in a six-pole machine.
