Title: Improvements in mountings of binocular sights
IPC: G02B7/12
Filed: 1930-12-09
Abstract: 360,238. Binoculars. BARR & STROUD, Ltd. and FRENCH, J. W., Caxton Street, Anniesland, Glasgow. Dec. 9, 1930, No. 37050. [Class 97 (i).] In a binocular sighting-device comprising two parallel telescopes &c. with reference marks in the field of view and with variable interocular distance, in order to avoid alteration in the attitude of the reference marks when the interocular distance is changed, the mounting provides two points of support for the telescope which are separated laterally and guided to produce curvilinear lateral movement without rotation of the telescope. In the form shown the telescope B is fixed on the support 3 and the telescope A is provided with arms 4, 5 pivoted to a frame 8 the opposite end of which is pivoted at 9 to the support 3 an extension 15 of the frame being engaged by the adjustment screw 14. Rotation of the telescope is prevented by a link 10 pivoted at one end 11 to the telescope and at the other end 12 to the support 3, the points 7, 11, 12, 9 being at the corners of a parallelogram. A spring 23 prevents shake in the bearings. In another form the link 10 is dispensed with and instead a projection from the telescope engages in a curved guide the radius of which is equal to the distance 7-9.

Abstract: 941,782. Nuclear reactors. GENERAL ELECTRIC CO. Ltd. Oct. 9, 1962 [Oct. 19, 1961], No. 37541/61. Heading G6C. In a core structure comprising moderator units assembled in vertical columns, the units through which coolant channels extend are supported end to end in substantial alignment by spigot and socket joints, one end face of each such unit having an annular recess into which a support spigot extends, the spigot providing a spherical bearing surface adapted to bear upon a co-operating annular surface within the recess so as to maintain a fluid seal between the co-operating faces of adjacent units while permitting a limited amount of misalignment therebetween. In Fig. 2 graphite blocks 1A and 1B are coupled together by a graphite collar 19 which fits into recesses formed in the upper and lower ends respectively of the blocks. The lower surface of collar 19 is plane and bears on a plane annular surface 17 whilst the upper surface of the collar is spherical and bears on an annular spherical surface 18. This limited relative horizontal movement, such as might be caused by an earthquake, is permitted and the fuel channel 6 remains substantially continuous and gas-tight. Block 1A is the lowermost block of a column and is spigotted to a support base 3 by a flanged spigot 4;the block is seated on a graphite collar provided with a spherical bearing surface 18 to provide a gas seal. In a modification the annular bearing surfaces 18 on the blocks are frusto-conical instead of spherical, the bearing surfaces on the collars 19 and 20 being spherical as before. The collar 19 may be integral with block 1A. Specification 941,781 is referred to.

In a gas-fuelled lighter in which the gas is ignited by means of a spark generated by application of pressure to a piezo-electric crystal element 1 and the discharge of gas is controlled by the means 11 for applying pressure to the element 1, the gas discharge nozzle 4 has an auxiliary discharge duct 17 located below a gap between spark discharge poles 9, 10, the gap being above and laterally offset from the nozzle. When the cap 11 is depressed the cam action of roller 3 pivots the lever 5 about a flange 12 and induces an axial movement of the spring-biased tube 4. Thus, gas flow is initiated from a reservoir 7. Continued pressure on the cap 11 further depresses hammer 2 and the element 1 thereby produces a spark between the electrodes.
