Title: Improved means for fastening tokens or tabs to coal or other hutches, corves, and such like
IPC: B65D55/10
Filed: 1920-05-25
Abstract: 158,487. Ross, A. F., and Forsyth, T. May 25, 1920. Addition to 119,362. Label fastenings.-In devices for securing tokens or tabs to coal corves &c. and of the kind wherein a staple c pivoted on the token a is provided with a locking-member f adapted to be passed through a hole in the corve and then turned through a right-angle and slid along so as to lie across the hole, the locking-member is provided with means for preventing its accidental displacement. In the construction shown in Figs. 1 and 3, the member f is contracted towards a waist i; in securing the token, the member is slidden from the position shown in Fig. 1 until the eyes e of the staple c reach the waist, after which the eyes e spring apart and occupy the position shown in Fig. 3. If the member f is open-ended, as shown in Fig. 4, the resiliency of this member instead of that of the staple is relied upon. In the construction shown in Fig. 6, the eyes e of the staple are passed through separate apertures n in the corve, and the locking- member f which is attached to one of them is engaged also in the other eye, the free end of the member being crimped at m to prevent its accidental displacement.
Patent GB-862258-A (GB)
Title: Improvements in or relating to over speed control apparatus for prime movers
IPC: G05D13/00
Filed: 1959-04-27
Abstract: 862,258. Fluid-pressure servomotor-control systems. WESTINGHOUSE ELECTRIC CORPORATION. April 27, 1959 [April 30, 1958], No. 14224/59. Class 135. A governor for a prime mover such as a steam turbine 10 having admission valves 12 controlled by a servomotor 14 has a prime mover driven hydraulic pump 22 feeding the servomotor 14 through a restriction 35, and a leak-off valve 30 controlling escape of fluid from the servomotor under the control of speed and acceleration means including a reverse flow governor pump 17 fed through a restriction 21 by the pump 22 and producing a pressure which is conveyed through a conduit 27 to a chamber containing a bellows 26 which, through a lever 31 loaded by a spring 32, controls the valve 30. The arrangement is such that increase of pressure in the conduit 27 due to an increase of speed of the prime mover results in opening of the valve 30 with consequent lowering of the pressure in a conduit 29, the servomotor 14 being arranged to close the admission valve in response to reduction of pressure. The valve 30 can also be operated by an acceleration responsive diaphragm 43 subject on its upper surface to pressure in a chamber 50 connected directly to the conduit 29 and on its lower surface to pressure in a chamber 52 connected with the conduit 29 by a first passage comprising a restriction 60, a duct 57, a variable volume chamber 53 containing a bellows 54, and a check valve 59, and by a second passage comprising the restriction 60, a duet 78, a restriction 76 and a duct 72. In response to a rapid acceleration of the prime mover the pressure in the chamber 50 falls at a sufficiently greater rate than that in the chamber 52 to cause the diaphragm 43 to rise to enable the valve 30 to release pressure from the conduit 29 at the still greater rate to cause a rapid closure of the turbine admission valves. Fluid under pressure will then escape from the chambers 52, 53 under the control of the restriction 60 until the bellows 54 has expanded whereupon the check valve 59 will close and the chamber 52 will continue to exhaust through the duct 72 and restrictions 76, 60 until the pressures on either side of the diaphragm are equalized. The downward bias on the diaphragm assembly due to the weight thereof determines the value of acceleration at which the diaphragm becomes effective. This bias may be substituted by a spring should the arrangement be such that the diaphragm assembly is mounted with its axis other than vertical.

Title: Improvements in centrifugal pumps and liquid seals supplied thereby
IPC: F04D1/12
Filed: 1950-06-08
Abstract: 673,520. Centrifugal pumps; stuffing-box substitutes. METROPOLITAN - VICKERS ELECTRICAL CO., Ltd. June 8, 1950 [July 29, 1949], No. 14334/50. Classes 110(i) and 122(v) [Also in Group XXXV] A centrifugal pump which may be used as a sealing device comprises a drum having an inwardly directed flange at its open end and, located within the drum, a disc which extends close to the cylindrical wall of the drum, either the drum or the disc being rotatable and provided with vanes or the like which rotate the liquid, the fixed member being provided with an outlet port at or near the periphery of the drum and an inlet port nearer the axis of rotation, both ports being substantially at right-angles to the direction of the rotating liquid. Oil from an annular tank 6, Fig. 1, passes by way of a pipe 7 and a suction passage 9 in a disc 5 to the interior of a drum 1, which is rotated by a motor 3. The oil is acted on by vanes 13, forming a liquid ring which discharges into a delivery conduit 11. Fig. 2 shows a pump 20 acting as a sealing device whereby the oil ring 23 prevents leakage of hydrogen from the casing 19 of a dynamo-electric machine 17. The temperature of the oil ring may be stabilized by water circulation (not shown) in the disc 21. When the machine is running, the pump 24 which supplies lubricating oil through a conduit 26 to a bearing 27 also supplies oil through a conduit 22 to the sealing device 20. A blow-off valve 30 keeps the pressure in conduit 22 constant. When the machine is stationary, the oil is supplied through conduit 22 by a pump 1, an oil cooler 28 being provided. The changeover is effected by a pressure-actuated switch 34 which closes the supply circuit for the motor 3 and for an electromagnetically-opened valve 8 when the pressure in the oil ring 23 falls consequent upon slowing down of the machine 17. A valve 29, actuated by the pressure developed by the pump 1, closes the connection of the conduit 22 to the pump 24 and opens its connection to the pump 1. Oil leaving the ring 23 passes through a clearance 37 and thence by a conduit 40 back to tank 6, and also through a clearance 36 to mix with the bearing lubricating oil. The mixed oil passes through a conduit 38 to the lubricating oil tank 25 by way of a device 39 which byepasses a proportion of the oil, equivalent to the quantity which has passed clearance 36, back to tank 6.
