Abstract: 605,555. Making valves; fillings. ECCLES, G. O., and TALBOT, G. L. Oct. 30, 1944, No. 21178. [Classes 83 (ii) and 83 (iv)] In a method of making hollow forgings by boring out a blank to form a cavity, forging the blank while the cavity is filled with a filler and finally forming an opening into the cavity and extracting the filler, the filler material comprises aluminium or paraffin wax and the forging is carried out at a temperature at which the filler will be in liquid form. The invention is described as applied to the making of a hollow poppet valve. A round bar is forged at the ends to form enlargements 11, 12, Fig. 1, and is bored to form a blind hole into which a rod 14 of aluminium is placed. The enlarged end 11 is then drawn down to close the open end of the hole on to the aluminium rod and the end 12 is compressed between dies 18, 19, Fig. 3; to form the enlarged head of the valve. The stem end of the valve is then drilled so that the aluminium may be removed. In a modification, the cavity is closed at the end 11 before the insertion of the filling material and is then drilled so that a filler such as paraffin wax may be run in after which the hole is closed by a plug which may be welded in. If the valve is required to have a comparatively large head, a larger round steel bar may be used, the stem portion being reduced by a swaging operation after the removal of the filling material.

Abstract: 962,266. Nuclear fuel elements. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. June 7, 1962 [June 13, 1961], No. 21377/61. Heading G6C. A support structure for a cluster-type fuel assembly comprises a contiguous assembly of cells, each cell comprising a single thin-walled member disposed edge on to the coolant flow past the fuel rods and bent to form a closed cell, an arcuate portion in the boundary wall of the cell, and at least two further portions of the wall inwardly formed relative to the cell to define, in conjunction with the arcuate portion, a fuel rod locating position. As shown, the structure is shaped as a sector of a circle subtending an angle of 60 degrees and comprises three cells 2, 3 and 4 spot welded together, six such sectors being spot welded together and to a support ring 8 to form a complete circular grid structure. The outer cell 2 comprises an inner uninterrupted arcuate portion and an outer arcuate portion interrupted by two V-shaped portions 5, the outer ends of the radial walls being chamfered at 6. The intermediate cell 3 is similar but has only one V-shaped portion 7, while the inner cell 4 has an uninterrupted arcuate outer wall and re-entrant portions in its radial walls. It is thus seen that each sector houses six fuel rods 1 so that where there is also a central fuel rod 1, the grid structure provides support for a thirty-seven rod cluster. Actual point contact between the fuel rods and the cells is provided by locating pips 9.

Title: Improvements in or relating to manually-operable selecting switches for use in intercommunication telephone systems
IPC: A44B11/04
Filed: 1931-07-28
Abstract: 382,635. Switches held set and freed mechanically. ASSOCIATED TELEPHONE & TELEGRAPH CO., 1033, West Van Buren Street, Chicago, U.S.A. July 28, 1931, No. 21530. Convention date, April 27. [Class 38 (v).] Switches, latching and unlatching.-A manually-operated line-selecting switch in an intercommunication telephone system is constricted by adaptation of the standard fingeroperated dial switch employed in automatic telephone systems, the selector being automatically latched after operation until released by replacement of the telephone receiver. As shown in Fig. 1, the selecting switch is operated by the usual rotatable finger hold plate 55 of the standard dial switch such as is described in Specifications 234,036 and 237,290, [both in Class 40 (iv), Telephones &c.], the operation of which rotates a spring contact finger 68 over spaced contacts 71 corresponding to the different lines in the system. The switch is automatically locked on being moved to engage any particular contact by means of a pivoted spring-controlled detent 80 having a projection 82, Fig. 3, adapted to ride over the teeth of a gear wheel 62 during the switch-operating movement and retain it in its displaced position, This detent is released by the replacement of the receiver between the jaws 8, the weight of the receiver operating switch-hook contact members 17, 18 as described in Specification 253,709, [Class 40 (iv), Telephones &c.], and also depressing a rod 19 which in turn rocks a pivoted plate 22 having a projection 27 engaging a down-turned extension 81 of the detent 80 which is returned under the action of a spring 58 at a speed controlled by the usual governor mechanism 64. To prevent possible damage to the gear wheel 62 due to the sudden re-engagement of the detent projection 82 during the return movement a spring-controlled trigger 87 is provided to engage automatically behind the projection 81 of the detent 80 on its release so that if the receiver is raised during the switch return movement the plate is held away until the trigger is engaged by a pin 91 carried by the moving parts which draws aside the trigger. Similarly if the selecting switch is operated before the receiver is lifted the trigger engages below the projection 81 and prevents the switch being latched in a selected position. In the circuit diagram shown in Fig. 6 the lines are connected to the contacts 1 .. 10, the line corresponding to the local telephone being connected by a lead 97 to the normally-engaged contact 70 of the selecting switch. The switch 17, 18 breaks a ringing circuit through a buzzer and completes a talking circuit, a local talking battery beng connected through a high impedance M. A pushbutton switch 75 is provided to produce on depression ringing impulses at a selected receiver after selection of the line has been effected.
