Title: Sealing conductors into vitreous envelopes
IPC: H01J5/42
Filed: 1933-03-08
Abstract: A leading-in or sealing-conductor which passes through or forms part of the envelope of a vitreous vessel having a coefficient of thermal expansion substantially equal to that of tungsten is formed, at least in part, of sintered tungsten containing a metal of lower melting point in a proportion so small that the coefficient of expansion of the mixture is substantially that of tungsten.  An example contains 2 per cent of nickel.  The metal of lower melting point may be added to the tungsten at different stages and in different forms.  Thus, oxides of tungsten and nickel may be mixed and reduced together, or the metal powders produced separately may be mixed.  The mixture may be pressed into the required form and then sintered, or the pressing and sintering may be simultaneous.  Alternatively the conductor, formed by pressing and preferably sintered may be dipped into molten nickel so that the latter is absorbed into its pores. Further sintering may then follow.  Specifications 5150/13 and 193,329, [both in Class 39 (ii)], are referred to.ALSO:A leading-in or sealing-conductor which passes through or forms part of the envelope of a vitreous vessel having a coefficient of thermal expansion substantially equal to that of tungsten is formed, at least in part, of sintered tungsten containing a metal of lower melting point in a proportion so small that the coefficient of expansion of the mixture is substantially that of tungsgen.

Abstract: 559,810. Controlling aircraft. GENERAL AIRCRAFT Ltd., WILLIAMS, L. C., and ANDRE DREWS, E. J. May 26, 1942, No. 7133. [Class 4] To increase the power of a tailplane and elevator assembly in aeroplanes having lift increasing flaps which cause considerable variation of load on the tail planes when moved from one position to the other, a gap is provided between the tail plane and elevator so that the elevator acts as a slotted flap as it is moved in one sense and with a decreasing slot effect when moved in the other sense, until, with the slot nearly closed, the elevator acts as a plain flap. As shown, an asymmetrical elevator 4<SP>1</SP> is pivoted about an axis 6<SP>1</SP> behind a tail plane 3 so as to form a slot 7<SP>1</SP> in its normal and uptilted positions. When the elevator is moved downwardly the slot effect diminishes. An assembly also is described in which the parts are in an inverted position, the selection of one or the other arrangement depending upon which direction, up or down, the more powerful elevator control is required. The elevator tapers in both thickness and chord towards the tips, and the slot also tapers reducing the gap towards the tip. According to the Provisional Specification the chord of the elevator is 20 per cent to 25 per cent of the total chord of the tail plane and elevator assembly and is movable through a range of angles from 25 degrees down to 50 degrees up.

Abstract: 707,147. Endless conveyers. ROSE BROS. (GAINSBOROUGH), Ltd. April 2, 1952 [April 3, 1951], No. 7657/51. Class 78 (1) A slicing and wrapping machine for loaves of bread of the kind in which the loaves are passed through slicing knives towards a chain conveyer for carrying the loaves to the wrapping elements and in which the loaves are transferred in succession to the conveyer by grippers operating in timed relationship with the conveyer, a feeler member actuated by the leading loaf operating to determine the gripping position, is characterised in that the grippers are carried by a pair of endless chains surmounting the chain conveyer. As shown, loaves 11 are fed through slicing knives 12 on to a belt conveyer 13 towards a gripping station 14 at which the loaves are seized by pairs of grippers 16 on a pair of endless chains 17 and transferred to a conveyer 18 leading to the wrapping machine. The conveyer 18 is driven in timed relationship with the chain 17 so that each pair of grippers 16 delivers a loaf on to a supporting platform 21 somewhat in advance of a pusher element 19 on the conveyer 18. Upon the arrival of a loaf at the gripping station 14, a feeler bar 22 is pivoted about its axis 28 and. through a link 32, pivots a stop member 26 about its axis 33 to move a pair of abutments 36 out of the path of projections 37, 42 on lever arms 29, 39. These arms, under the influence of springs, then follow cams 23, 25 respectively mounted on a driven shaft 30. The feeler bar 22 falls clear of the loaf and links 38 connected to the lever arms 39 operate the grippers 16. The chains 17 then carry the loaf to a position above the support 21 when the cams 25 operate to release the grippers and cams 23, 24 return the feeler bar 22 to its operative position, the projections 37, 42 co-operating with the abutments 36 to prevent the arms 29, 39 following their cams until the feeler bar is again engaged by a loaf. The chains 17 are each carried by a pair of sprockets 43 mounted on shafts 44 housed in bearings 46 forming part of a chain support 47 pivotally mounted on parallel motion links 48, 49, pivoted on the framework of the machine, the link 49 being connected to the link 38. The arms of the members 46 are inclined so that as the gripper 16 move towards the gripping position they move. towards the loaves and so avoid the possibility, with some types of loaf, of the grippers catching the loaves as they approach, the gripping station.
