Title: Cathode-ray tubes
IPC: H01J29/89
Filed: 1971-05-05
Abstract: 1324565 Cathode-ray tubes and image pick-up tubes SIEMENS AG 5 May 1971 [14 May 1970] 13269/71 Heading H1D A cathode-ray tube includes a post-deflection accelerating lens comprising electrically conductive hollow member 2, with open exit and entry apertures, the edge of the member adjacent the screen electrode being shaped so that the perpendicular distance from the plane of the screen electrode is less at the corners than at the middle of any edge of the screen electrode 1. Preferably the edge of the hollow member adjacent the screen electrode is matched to the symmetry of the screen electrode. The hollow member may be shaped as a cone or pyramid, or may be cone-shaped adjacent the deflection system and merge into a pyramidal shape adjacent the screen electrode. Also the member may be a lining or coating on the tube envelope. Reference is made to pin cushion distortion and lack of definition and elimination of errors formed by employing an open exit aperture instead of a metal gauze exit aperture. The potential differences between the screen electrode and hollow member will be larger, the greater the angle between the central beam path and the wall of the hollow member. With tubes incorporating a mask before the screen, the accelerating field is applied to take effect before impingement of the electrons on the mask, and in multi-gun tubes this may lead to a reduction in convergence difficulties and increase in brightness. Applicability to tubes having central deflection systems such as oscilloscope tubes, monochrome or colour picture tubes and camera tubes employing high velocity electron beams is exemplified.

Title: Improvements in or relating to the decarbonization of carboncontaining metals and ferro-alloys
IPC: C21D3/04
Filed: 1938-05-04
Abstract: 514,491. Decarburizing iron &c. RENNERFELT, J., and KALLING, B. M. S. May 4, 1938, No. 13319. Convention date, May 5, 1937. [Class 72] Carbon-containing metals or ferro-alloys in granular form are decarburized by heating them in a rotating tubular furnace to a non- melting temperature and blowing air or oxygen containing gas directly on to the inclined surface of the charge and away from the upper furnace wall and in amounts causing incomplete oxidation of carbon monoxide generated from the metals in close proximity to the hot metallic grains. The heat necessary for heating the charge is produced for the major part by the exothermic oxidation of the carbon monoxide. The velocity of the inner surface of the wall is maintained at not less than 5 metres per minute and the furnace is filled to at least 25 per cent. of its cross-section in the hottest zone of the furnace: The decarburization mav be effected to produce a superficial oxidation of the granules an additional reduction of the carbon content then taking place when the product is subsequently melted. The granules may be classified in size before and/or after treatment and may be mixed with iron oxide. The metallic granules are fed through an opening 3 into the rotating furnace 1 and air is fed by a pipe 6 eccentrically located in the opening 3 and provided with nozzles 7 directed downwards. Within the tube 6 is located a tube 8 through which may be introduced a fuel gas which is thus admitted into the final decarburizing zone of the furnace. Fuel gas may also be admitted through a pipe 9 placed in the exit 5 of the furnace. The decarburized granules pass through a cooling device 10 provided with baffles 11 having apertures 12 therein and immersed in a tank 13. The process may be applied to metals such as iron, nickel, cobalt and molybdenum and to ferro-alloys such as ferro-molybdenum, ferrotitanium and ferro-vanadium. Specifications 484,662 and 504,122 are referred to.

Abstract: 446,136. Free-wheel clutches. MACKAY, J., 8, Hutchison Road, YOUNG, W. T., 92, Polwarth Gardens, and McVITTIE, C. R., 16, Leamington Terrace, all in Edinburgh. May 7, 1935, No. 13390. [Class 80 (ii)] In driving-gear for cycles comprising spring- pressed forward-drive and backward-drive pawls 9 and 10 carried by a ring 6 secured to the wheel hub and co-operating with teeth 15 in the interior of the sprocket wheel 16, the pawls 10 are controlled, so as to render the drive alternatively unidirectional or bidirectional, through a semicircular wire link- 19, the bent ends of which engage grooves 18 in the side faces of the pawls 10. A pin 20 secured to the link 19 passes through elongated slots in the ball bearing rings 17, 31 and is adjustably secured to a rod 24, the other end of which is pivotally connected to a member 23 pivotally mounted on the ring 17. A fork 26 is formed on a lever 28 pivoted in a bracket 27 suspended from the axle pin. A part 44 of the rear fork of the frame engages a notch 43 in the bracket 27 to prevent turning of the latter. With the lever 28 held by a spring 40 in the normal position shown in dotted lines in Fig. 2, the fork 26 co-opera,tes, on forward rotation of the wheel, with the member 23 to turn the latter and thereby move the link 19 so that its bent ends engage the grooves 18 near the pawl pivots, whereby the pawls 10 are free to turn, and the drive is bidirectional. By rocking the lever 28, through a connection 29, into the position shown in full lines, the link 19 is moved so that its bent ends engage the grooves 18 near the free ends of the pawls, as shown in Fig. 4, thus holding the pawls 10 in inoperative position. A slotted plate spring 38 is fitted between the head of the pin 20 and the ring 7.

IPC: F42C14/04
Filed: 1917-09-18
Abstract: 129,009. Elia, G. E., Feb. 21, 1917, [Convention date]. Mines, marine.-Consists in making these with a spring-striker cocked and released by the pull of a line connecting the depth charge to a float, the length of the line determining the depth at which explosion takes place, somewhat as described for explosive booms in Specification 6426/15. As shown, the line 9 connecting the float 10 to the depth charge 8 is coiled round a drum 25 in the depth charge, and the drum screws over a spindle 18 interlocked with the spring striker 16 by radial bolts 19. The effective length of line is regulated by screwing or unscrewing the spindle 18 and then locking it by a spring catch 28 which engages a longitudinal groove on the spindle. When the depth charge is thrown and sinks in the water, the line is paid out and rotates the drum. This draws out the spindle until the radial bolts 19 are wedged out into an enlargement 20 of the tube enclosing the striker. The striker is thus released and fires a detonator 15 exploding the charge 12.

Abstract: 747,817. Pressure gauges; indicating-apparatus. SMITH & SONS (NOTTINGHAM), Ltd., S. Oct. 30, 1952 [May 29, 1952], No. 13689/52. Classes 106 (2) and 106 (4). Link-and-lever mechanism 23, 17, 18 transmitting motion from the operating element of indicating or recording apparatus, e.g. a Bourdon tube 4 to the pointer &c. 19 is constructed to provide one ratio of movement for a low part of the range and a higher ratio for a higher part of the range, a stationary abutment 33 cooperating with the link and lever mechanism to change from one ratio to the other, lost-motion connections being provided between the link and lever mechanism, the indicating or recording element and the abutment. The invention is shown applied to a pressure gauge with edgewise type dial mounted by a T-shaped frame 3, 7, 9, 11 in a casing 1 having a removable front cover la. The frame part 7 carries a scale strip 2 and the part 11 supports the Bourdon tube 4 connected by a capillary tube 5 to an inlet pipe 6 which is fixed to the casing 1 and has a mounting 6a connected to the frame part 11 which carries spaced therefrom a strip 12, a block 14 connecting the tubes 4, 5 lying between the strips 11, 12. The strips 11, 12 also provide bearings for a pivot pin 17 attached to a return spring 25, Fig. 2, and also to an arm 26 and link 18 pivoted to pointer 19 constrained by a peg 21 riding in a slot 22 so that a bent-over part 20 of the pointer 19 co-operating with the scale 2 moves parallel thereto. The Bourdon tube 4 causes displacement of the pointer 19 through linkwork connecting a slotted arm 23.to the arm 26 and comprising two links 30, 27 both pivotally interconnecting the arm 26 and a lever 31 having a peg 32 riding in a slot 33 of a fixed arm 34, the lever 31 and arm 23 being pivotally interconnected by a link 39 pivoted to the lever 31 at the same point as the link 27. In the zero position of the pointer, determined by the engagement of the arm 26 with a peg 36 on an arm 35 adjustably mounted on the strip 12 by pin and slot connection, the pivot pin 28 of the arm 26 engages the lower end of a slot 29 in the link 27 and when the arm 23 rises with a rise of pressure the arm 26 turns the pivot pin 17 comparatively slowly through the link 27 until the peg 32 reaches the top of the fixed slot 33, thereafter the link 31 rocks clockwise causing the link 30 to rotate the arm 26 and pivot pin 17 faster, thus opening out the scale over the ensuing range of movement, the pin 28 now riding up the slot 29. For initially setting and subsequently varying the leverage motions of the mechanism adjustments may be made by forming the link 39 in two superimposed parts with screw-and-slot connections, the arm 23 may be connected to the link 39 by screw-andslot and the arm 26 may carry a subsidiary lever which is fixed by a screw 43 and to which the links 27, 30 are connected. The apparatus may be adapted for recording on a travelling sheet. Specifications 616,161 and 656,775 are referred to.
