Title: Improved means associated with cranes for the operation of tip-buckets
IPC: B65D88/56
Filed: 1919-10-31
Abstract: 159,811. Macnamara, C. M., and Reid, W. Oct. 31, 1919. Tip-buckets.-Means for operating tip-buckets, of the type in which a crown-piece or weight, suspended from the crane jib, co-operates with a lever to disengage locking-dogs associated with the bail and engaging the rim of the bucket, are provided with guiding-means to ensure the tipping of the bucket in a predetermined selected plane. The crane jib carries three pulleys in line, the centre pulley supporting the hoisting-rope k and the outer pulleys the hollow crown-piece C. The distance between the outer pulleys is such that the crown-piece does not rotate bodily during the tipping-operation. Guide-ribs q, formed internally on the crown-piece or on an inner member mounted therein, co-operate with a projection u to lead the latter into a slot n which fixes the plane of the rising bucket prior to the tipping-operation. The inner member can be rotated relatively to the crown-piece to vary the plane of tipping, or the crown-piece can be rotated bodilv by manipulation of the crane. On further rising of the bucket after the fixing of the plane, a rod j is depressed by contact with the rim r. This movement is communicated by pin-and-slot connections to levers f which raise latches on the ends of levers e from the rim of the bucket and allow the latter to tip by gravity. The latches are bifurcated to engage the bail, and the levers e are guided by links s, the arrangement of parts being such that the latches and levers as a whole are within the confines of the bail. The bail may be fitted with means to limit the tipping of the bucket to one side only. The bucket may also be positioned and tipped by allowing the crown-piece to fall while the bucket is stationary.

Title: Improvements in and relating to coil windings for dynamo-electric machines
IPC: H02K3/14
Filed: 1926-12-28
Abstract: 263,833. British Thomson-Houston Co., Ltd., (Assignees of Summers, I. H.). Dec. 29, 1925, [Convention date]. Coils.-In a method of reducing the eddy current losses in multiple layer coils for dynamoelectric machines by transposition of the component layers of a laminated coil conductor from slot to slot, a twist of 180‹ is given to the laminated conductor at one end of the coil. The Specification analyses the parasitic voltage distribution across the conductors in a given slot into an elementary parabolic component and a linear component which increases from zero at the bottom of the slot to a maximum at the top of the slot in direct proportion to the number of conductors in the depth of the slot, and it is shown that the present method of twisting approximately balances out the effects of the linear components in the two sides of the coil. Fig. 1 shows a two-turn, two-layer coil composed of four-strand conductor, each strand being made of two wires and insulated from the other strands. The coil has the usual reversing ends 2 and, according to the invention, it is given a twist of 180‹ in such turn, as shown at 6, the resulting effect being shown in Fig. 2, which is a section on the plane 2-2, Fig. 1, and in which a selected strand is shown in shaded lines. Fig. 3 shows a three-turn three-layer coil having four double strands insulated from each other as in Fig. 1. The coil has the usual reversing ends 12 and has a single twist 16 through 180‹ at the front end. It is shown in the Specification that the linear parasitic voltage components completely cancel out in the form shown in Figs. 1 and 2 and that in the form shown in Fig. 3 they are reduced to one-ninth of the value which they would have without the twist at 16. Fig. 3 shows the twist in the top conductor at the connection end of the coil, but it may also be at the other end of the coil in the end of the bottom conductor in the top coil side, an arrangement which gives a smaller reduction of losses but a coil twist at a place where there is more room available than there is at the connection end. The terminals 4, 14 may also alternatively enter the slots at the top in place of the bottom as shown, in which case the point of twist is placed at the back end of the coil one turn distant from the terminal.

Title: Metering valves for pressurised containers
IPC: B65D83/14
Filed: 1959-10-01
Abstract: 872,187. Dispensing measured quantities of liquids. RISDON MANUFACTURING CO. Oct. 1, 1959 [Nov. 10, 1958], No. 33271/59. Class 106(5) [Also in Group XXVIII] - A device for dispensing measured quantities of liquid from a pressurized container 22 comprises a measuring chamber 50 formed in a valve housing 34 having intake and discharge ports 72, 56 for connecting the chamber with the interior of the container and with atmosphere respectively, valve means 70, 62 associated with each port, and a closed auxiliary chamber mounted on the housing and in continuously open communication with the chamber intermediate both ports. The valve housing 34, of a suitable moulded plastic material, has a flange 36 sealingly clamped by a cap 38 against a flange 40 formed on a resilient sack 42, the interior of which, together with the exterior of the valve housing and a dip tube 32 secured thereto, defines the auxiliary chamber 80. A hollow valve plunger 52 passes into the chamber 50 through a sealing ring 60 and is arranged at its lower end, to co-operate with an elastomeric valve plug 70. In operation, liquid in the container, which is pressurized by a gas, such as nitrogen, in the space 30 above the liquid, is forced by the gas up the tube 32 through the inlet space 72 into the chamber 50 and thence through a number of ports 82 into the chamber 80, escape of the liquid from the container being prevented by a ridge 54 on the plunger engaging a resilient sealing washer 62. Upon depression of a nozzle 26 secured to the plunger 52, the latter acts against the valve plug 70 so as to close off the inlet space 72 and, after further depression, bring the port 56 in the plunger into communication with the chamber 50, the liquid in the chamber 80 then being dispensed due to the collapse of the resilient sack under the action of the gas pressure in the space 30; in the case when the propellant gas readily mixes with the liquid being dispensed, the admixture contained in the chamber 50 is also dispensed under the action of the gas contained therein. The container is filled by removing the nozzle 26, fitting a filling head over the end of the valve plunger 52, depressing the plunger so as to bring the ports 56 into communication with the chamber 50, then forcing the liquid under pressure through the ports 56 into the chamber 80 thereby lifting a sealing lip 43 out of contact with the dip tube 32 so that the liquid may enter the container (Fig. 5, not shown). Fig. 6 shows, inter alia, a modified form of the nozzle 166 and method of clamping the valve housing 116 and resilient sack 154 to the container 112, the flexible lip 160 of the sack engaging an extension of the valve housing; the function of the device is identical with that previously described. Specification 798,169 is referred to.
