Abstract: 144,964. Veron, A., and Veron, J. Dec. 8, 1919. Bell-operating mechamism, electric; bell cases or covers; bells, fixing.-In an electric bell of the type comprising a solenoid coil provided with a reciprocating core which acts as a striker, the core is held normally in equilibrium by two unequal springs acting in opposition. In Fig. 1, which shows a construction adapted for continuous current, the core is in two parts c and e. When the circuit is closed the part e is drawn into the solenoid against the action of the spring g and the circuit broken by the interrupter b. The spring g then causes the core e to strike the gong i, the weaker spring h restoring it out of reach of the gong. In a modification, the core c may be connected at one end by a spring to a fixed point, and carry at the other end an adjustable screw which makes and breads contact with a spring on the interrupter b. The construction shown in Fig. 5 is adapted more particularly for operation by alternating cunent, c<1> being the stronger and d<1> the weaker spring. The bell is intended to be included on an electric light circuit and may be fixed to a wall by a bracket supporting the gong and secured to a cover protecting the coil. The springs and contacts are also enclosed by a protective covering.

Title: Improved moulds for casting synthetic resins, for example for optical elements
IPC: B29D11/00
Filed: 1945-11-16
Abstract: 599,782. Moulds for casting optical elements &c. from synthetic resins. SILBER, M. H., GREENWOOD, W. A., CROOKS, C. H., and IMPERIAL CHEMICAL INDUSTRIES Ltd. Nov. 16, 1945, No. 30780. [Class 87 (ii)] A mould is made by pressing two glass plates 1, 1A, Fig. 1, (Prov.) having plane parallel surfaces, against plane polished surfaces X, X<1>, of angle pieces 2, 2A, and sandwiching and pressing a glass plate 3, also having plane parallel surfaces, between other plane polished surfaces Y, Z on the angle pieces, the pressing operations being carried out with forces which cause the appearance of interference bands at the glassangle piece interfaces. The interference bands are a function of the thin films of air between the surfaces of the angle pieces and the glass plates, and the bands broaden as the surfaces approach perfect parallelism. To obtain highest possible accuracy the bands should be as broad as possible. All angle piece-glass interfaces have at least a portion visible. The forces are applied by clamps &c. through the intermediary of resilient pads. The mould shown in the said Fig. 1 is for casting a prism, e.g., by the process described in Specification 582,248, and a cover-plate 4 is used. The edges of the cover-plate may be bevelled, to facilitate removal by prising. In a modification (Fig. 2, Prov., not shown) the angle piece 2A is replaced by a flat plate and one glass plate is used instead of the two glass plates 1A and 3 In a second modification (Fig. 3, Prov., not shown) three angle pieces and two plates 3 are used. Fig. 3 (Comp.) shows a mould made from three right-angle pieces 8, 9, 10, three glass plates 11, 12, 13, and a suitable coverblock, for making binocular prisms. The surfaces which back the exposed glass surfaces may be cored to carry heating or cooling fluids. Specifications 569,684 and 582,559, [both in Group IV], also are referred to.

IPC: G21C13/067
Filed: 1962-08-14
Abstract: 948,233. Stud and socket fastenings. COMMISSARIAT A L'ENERGIE ATOMIQUE. Aug. 14, 1962 [Aug. 16, 1961], No. 31209/62. Heading E2B. [Also in Divisions F2 and G6] The invention provides a plug and inserter for nuclear reactor fuel channels which can be locked in position therein by pawls which are themselves locked, and includes provision for ensuring that the plug is locked before the plug inserting device is withdrawn. The fuel channel tube 13 includes an annular recess 85 and a seating shoulder 99a. The plug comprises a body 11, a locking member 121 urged upwardly by a spring 129, and three or more locking pawls 120 pivotably mounted in the plug portion 126 within grooves 134 therein. The inserter comprises a guide and sealing tube 47 within which is situated a handling clamp 122 having grab levers 123 and a grab lever actuating rod 131 axially movable within and independently of the handling clamp 122. In its inserted position (Fig. 1), the plug rests on the channel tube shoulder 99a, and is retained in this position by the pawls 120 engaging the channel tube recess 85; sealing is provided by the members 103. To unlock and remove the plug, the sealing tube 47 is positioned on the channel tube end as shown, and the handling clamp 122 lowered until its grab levers 123 abut a shoulder 126 in the top of the plug. The actuating rod is moved upwardly, which causes its annular portion 131a to contact the upper end of the grab levers 123 outwardly and thereby engages shoulders 125 within an annular recess 127 in the locking member 121. The handling clamp and actuating rod are moved simultaneously downward until the projection 124 is situated below the shoulder 126; since the shoulder 125 is engaged in the recess 127, the locking member 121 will have been pushed down, thus unlocking the pawls 120. The position now reached is shown in Fig. 3. The actuating rod is moved downward, thus causing the lower annular portion 131a to move the grab levers 123 outwards to the position shown in Fig. 4, in which they hold the pawls out of engagement with the recess 85, and still restrain the locking member 121 from moving upwards. The plug can now be withdrawn by raising the handling clamp 122. Insertion of the plug follows the above procedure in reverse, and it is to be noted that during insertion of the plug, it is impossible to disconnect the handling clamp unless the pawls have correctly engaged in the channel tube recess.
