Abstract: 670,729. Valve closure members. ARMSTRONG, C. H., and COPES REGULATORS, Ltd. May 11, 1950 [June 10, 1949], No. 15479/49. Class 135. A valve for supplying feed-water to a high pressure steam boiler comprises a valve body 1, Fig. 1, having inlet and outlet connections 2, 3 and concentric hollow ported valve members 9, 4, 7. The middle member 4 is screwed to the body 1 and formed around its periphery with a number of equally spaced rectangularshaped ports 6, Fig. 4, whilst the members 9, 7 are secured to an operating spindle 12 and formed with similarly spaced V shaped ports 10 and 8 respectively. The ports 10, 8 are aligned with each other and so dimensioned that at any cross-section through the members 9, 7 the width of a port 10 is always less than that of a port 8. The width of a port 6 is made substantially equal to the maximum width of a port 8. The ports 8, 10 may be adjusted axially with respect to the ports 6 by rotation of a handwheel 19 formed integral with a housing 18 which co-operates with the body 1 and houses a spring 20 between thrust bearings 21 which bear on a nut 23 and a collar 22. The members 9, 7 are rotated with respect to the member by a lever 17 to open and close the valve. The arrangement is that for any axial adjustment of the valve members the ports 10 will overlap and shroud the ports 6 when the valve is fully open, so that the adjacent surfaces of the members 9, 4 are shielded from direct fluid flow and hence wear and pitting thereof is reduced. When the valve is designed to pass fluid in the reverse direction the widths of the parts 8, 10 are interchanged to produce the shielding effect on the adjustment surfaces of the members 7, 4. Ports of other shapes may be used provided the ports through which the fluid first passes shroud the subsequent ports when the valve is fully open. Specifications 303.238, [Class 135], and 458,378 are referred to.

Title: Improvements in and relating to gas blast electric circuit breakers
IPC: H01H33/32
Filed: 1952-06-23
Abstract: 723,156. Gas-blast switches. BRITISH THOMSON-HOUSTON CO., Ltd. June 23, 1952 [June 26, 1951], No. 15759/52. Class 38 (5). An operating mechanism for a gas-blast circuitbreaker having an isolating contact 6 and an interrupting contact 4 comprises a blast valve 14 to control the supply of gas to the interrupting contact, the valve 14 being operated by a piston 19 having a projecting undercut portion 44 which acts as a sleeve valve to admit gas to a fluid motor 23 controlling the operation of the isolating contact. In the multi-pole arrangement shown, when a main valve 21 is opened, gas pressure is applied through conduits 20 to pistons 19 which move upwardly opening the blast valves 14. Gas now flows through conduits indicated at 18 to the circuit-breaker units 1 ... 3, the blast opening finger contacts 4 against the bias of springs 5 and extinguishing the arcs drawn. During the upward movement of the pistons 19, the undercut portions 44 of the piston rods 15 establish communication between ports 46, 47. Compressed gas now flows through conduits 48, 49, 50 and 43 to the fluid motor 23. The resulting downward movement of the piston 42 " breaks " an overset toggle 35, 36 so that a spring 33 aided by the piston 42 and gravity moves a connecting rod 32 to the right. The rod 32, through " straight-line " linkages 25, 27, 29, moves the isolating contacts 6 downwardly to complete the opening and isolation of the controlled circuit. When the master valve 21 is closed, springs 16 close the blast valves 14 and the contacts 4 return to their initial positions. The isolating contacts 6 are restored by opening a valve 54 so as to supply gas through a conduit indicated at 55 to the underside of piston 42. If the circuit-breaker is to operate as a reclosing circuit-breaker, a valve 51 is closed to prevent the supply of gas to the fluid motor 23 so that only the contacts 4 may be operated under the control of the valve 21. Specifications 549,756, 583,346 and 712,436 are referred to.

Title: Improvements in or relating to check sorting and endorsing machines
IPC: B07C3/04
Filed: 1946-05-24
Abstract: 623,020. Sorting or filing cheques. INTERNATIONAL BUSINESS MACHINES CORPORATION. May 24, 1946, No. 15781. Convention date, Aug. 9, 1945. [Class 146 (i)] [Also in Group XVI] A machine for endorsing cheques as they are sorted into compartments, comprises a printing " cylinder " carrying elements for printing a " partial " endorsement and supplementary elements for printing, with the first mentioned elements, a " full endorsement, the selection of the compartment determining whether full or partial endorsement is effected. In the machine which resembles that described in Specification 531,922, the compartment 17 of a wheel 10 into which a cheque is to be fed is selected by key-controlled mechanism. After this, a motor-release bar is depressed to couple the drive of feed rollers 48, 53, 58, 61, Figs. 4, 8, to the driving motor and the cheque is fed by hand from a table 18. Situated between the rollers 58, 61 and cooperating with a platen 90 is a printing " cylinder 70, Fig. 7, carrying an electrotype, 82 for printing the name of the bank and typewheels 77, 78 projecting through a slot therein for printing the date and a number respectively. The " cylinder " 70 is mounted on a shaft 75 geared to the shafts of the feed rollers and carried by arms 88, 89 pivoted on a cross-bar 55. Between the arms 88, 89, two other arms 93, 94 are pivoted on the bar 55 and carry a rod 95 on which two rollers 96, 97 are mounted, the latter being slidable thereon. Springs 99 tend to move the arms 88, 89 so that the " cylinder " 70 contacts the platen 90 but normally this is prevented by studs 101 on these arms engaging the arms 93, 94, the roller 97 on which is bearing on a circular disc 98 on a shaft 103 geared to the feed rollers. If the roller 97 is moved to the left, Fig. 7, out of engagement with the disc 98, the springs 99 cause the roller 96 to engage a cam 110, Fig. 8, on the shaft 103. In this condition, when the machine operates a cheque is printed from both the electrotype and the typewheels, i.e., it is fully endorsed. If, however, the roller 97 is moved to the right, Fig. 7, it engages a cam 126, and the combined action of the cams 110,126 on the rollers 96, 97 causes printing to take place only from the type-wheels, i.e., for partial endorsement. Movement of the roller 97 is effected by a forked member 119 fixed to an axially-slidable rod 117 carrying a pin 106 engaging a slot in a lever 114 pivoted at 109, Fig. 6, and moved in one direction when an electromagnet 111F, Fig. 8 is energised and in the opposite direction when another electromagnet 111P is, energised. Scissor-levers 123, 124 joined by an adjustable spring 125 engage a pin 113 on the lever 114 to restore the parts to normal positions. Contacts closed by depression of a compartment selecting key can be connected by plug contact to the electromagnets so that cheques entering compartments can be either fully or partially endorsed, or so that all the cheques are either partially or fully endorsed.
