Abstract: 750,270. Generating arrangements. BRITISH TELECOMMUNICATIONS RESEARCH, Ltd. Jan. 14, 1955 [Feb. 8, 1954], No. 3693/54. Class 38 (4). The driving of a generator, upon failure of a main prime-mover, is taken over by a stand-by engine or motor which is automatically started up, the drive being maintained during the starting period of the stand-by machine by a hydraulic or other fluid-pressure motor automatically connected for supply from a fluidpressure accumulator when the main primemover failed, the accumulator normally being maintained charged by means energized by the generator. In the arrangement shown in Fig. 1, an alternator 10 is driven by a hydraulic motor 12 which is supplied either by pumps 14, 18- driven, respectively, by main and stand-by prime movers 13, 17-or by an accumulator 21, normally maintained charged by a motordriven pump 24, 25 supplied over a switch 29 from the alternator. Valves 16, 23 automatically shut and open, respectively, upon failure of the main machine 13, say as a result of the fall in speed, or frequency, of the alternator, valve 23 subsequently closing and valve 20 opening when the pressure developed by pump 18 of the stand-by machine reaches working value. The re-charging switch 29 and associated valve 27 may be controlled by the pressure obtaining in the accumulator. In a modified arrangement the hydraulic motor is in service only during the change-over period between main and stand-by drive.

Abstract: 1,087,213. Tachometers. V.L. CHURCHILL & CO. Ltd. March 3, 1966 [Jan. 27, 1966], No.3775/66. Heading G1N. A tachometer for measuring the rotational speed of a diesel engine comprises a pressure sensitive detector which is clamped on to the fuel injection feed pipe in the engine's fuel system so that the dilation of the pipe by the injection of fuel stimulates the detector to provide an electrical signal representative of the dilation. A signal representative of the frequency of dilation of the pipe and therefore of the rotational speed of the engine is then derived from this. The detector comprises two stainless steel members 4, Fig. 2, mounted in a U-shaped alloy clamping member 1, which are held against opposite sides of the pipe by adjustment of screw 12. The outer faces of members 4 bear against the ends of Piezo-electric crystals 11, surrounded by sleeves 6 of insulating material. Contact screws 22 provide electrical connections to the outer ends of the crystals, through brass pads 5, and contact screw 23 provides an electrical connection to their inner ends. The voltage signal from the crystals is fed via a flexible cable (24), Fig. 1 (not shown), to a pre-amplifier (21), Fig. 3 (not shown), and then to an amplifier (14). A voltage representative of the frequency is finally read off from a meter (16), connected to the output of amplifier (14). A switch (20) is provided by which the device can be used for 2 or 4 stroke engines, an additional resistance being inserted in the meter circuit by the switch to halve the reading on the meter for a 2 stroke engine. The condition of a battery (15) supplying power to the amplifier (14) can be checked by connecting it to a meter (16), Fig. 1 (not shown), via a suitable resistance (not shown), when a button (19) is pressed.

Title: Improvements in means for use in discharging the cargoes of ships, and for transporting goods from one point to another
IPC: B63B27/18
Filed: 1919-02-22
Abstract: 139,592. Vivian, R. E. Feb. 22, 1919. Overhead travellers and transporters.-Relates to means for discharging the cargoes of ships and transporting bales, cases, packages, &c. from one point to another in yards, and is particularly applicable to landing the catches of fishing-vessels. The catch is placed in a basket which is detachably connected to the hook E by a slip-hook e<3>. A sheave e is mounted in the hook E, and the nose of the hook is formed with an aperture to receive a hook f which is connected to the hoisting-rope D by a bridle F. The inclined rope A along which the sheave e runs to the shore is arranged between the ropes D, F, so that these ropes guide the sheave on to the rope during hoisting from the hold. When the full basket is detached at the shore end, the hook f is engaged with a ring F<1>, Fig. 5, which is loosely mounted on the rope A, and an empty basket is attached. During the travel of the sheave up the rope, the hook E gradually turns into the perpendicular position, and when this position is attained, the rope D is slackened arid the hook f becomes disengaged from the ring F<1>. The hook E can then be lowered into the hold. In a modification, the rope A is connected to a jib which is mounted in an upright at the bow of the vessel, and the sheave e travels along this jib to the shore. As the ring F<1> cannot be used in this modification, means are provided for turning the block C to throw the sheave c clear of the rope A. In another modification for transporting goods on land, the rope A is supported by uprights G, Fig. 8, and the rope D is detachably connected to the hook E by a plate e<7> which has a hook at its lower end for engaging a notch in an extension e<5> of the pin of the sheave e, and a pivoted U-link e<10> for engaging a projection c<11> on the top of the hook E.

Title: Priming mechanism for centrifugal pumps
IPC: F04D9/00
Filed: 1932-02-15
Abstract: 386,144. Centrifugal pumps. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.- (Nash Engineering Co. ; South Norwalk, Connecticut, U.S.A.) Feb. 15, 1932, No. 4491. [Class 110 (i).] Mechanism for priming a centrifugal water pump comprises an air pump, a control chamber communicating direct with the inlet of the centrifugal pump, and connections from the control chamber and from atmosphere respectively to the air pump, both of said connections being controlled by a vent valve adapted to open the connection from atmosphere to the air pump when the water reaches a predetermined level in the control chamber, the stem of the valve being so formed that the valve first throttles the connection between the control chamber and the air pump and thereafter admits a progressively increasing quantity of air to the air pump as the water rises above said level. The impeller 10 of a centrifugal water pump draws in water through the parts 12, 13, 14. On the same shaft 31 as the impeller is secured the rotor 30 of an air pump driven by a motor M. Passages 32, 33, 35 connect this pump with a control chamber 20, provided with a ball float 52 operating a valve 22, the top of the valve being subjected to atmospheric pressure. The valve stem 51 is of reduced diameter at its lower end 59, and formed with tapered flutes 58. It works in seat bushings 54, 55 secured in a cover 34 of the chamber 20. During the initial priming, air is drawn out of the water inlet 14, through the chamber 20, and into the passage 35 through the bushing 55 and flutes 58, the valve being closed as in Fig. 2. The water will pass into the inlet 14 to start the pump and continue to rise, together with entrained air, into the chamber 20, lifting the float and valve stem 51 so that the flutes 58 pass up into the bushing 55, and the connection between the chamber and passage 35 is reduced to the small clearance between the stem 59 and bushing 55. There is a progressive increase, however, in the flow of air into the passage 35 through bushing 54 and the flutes. If the pressure in passage 35 becomes greater than that in the chamber 20, there will be a slow leakage of air into the latter through the restricted passage surrounding the stem 59. This leakage is so controlled that the water drops slowly. The air flow through bushing 54 now decreases until the vacuum in passage 35 is sufficient to cause a slight flow from the chamber 20. The water column will be brought to a complete stop in practically one operation, and will be kept at a constant height during pumping. To prevent water passing into the air pump, the nut 53 on the valve stem, and bottom of the bushing 55 are shaped to form a valve and seat, which closes when water reaches an excessive height. To reduce eddy formation, baffle plates 60, 61 are arranged between the pump intake 14 and chamber 20. In a modification, a removable grid is employed instead of baffles.
