Title: Improvements in and relating to tipping-off devices for tubular electric lamps
IPC: H01J9/40
Filed: 1951-04-09
Abstract: 683,191. Sealing tubular electric lamps. BRITISH THOMSON-HOUSTON CO., Ltd. April 9, 1951 [July 12, 1950], No. 8184/51. Class 39(ii) In a device for sealing or tipping- off vitreous tubes extending from electric lamps and like devices, more particularly tubular fluorescent lamps, and comprising a floating bearing member which supports the heating means and is movable laterally in order to compensate for misalignment between the heating means and the vitreous tube upon which it is to operate, as claimed in Specification 634,119 means are provided for automatically recentring the floating bearing member, and the heating means mounted thereon, with respect to the housing within which the floating bearing member is located. As shown in Fig. 1 a tubular rod 20 which is slidable vertically within a sleeve 22 is provided at its lower end with a transverse pin 41 to which the lower end of a tensioned helical spring 40 is connected, the upper end of the spring being connected by a wire 42 to a pin 43 at the centre of the floating disc 17, which is supported upon two concentric rings of ball bearings 18, 18<SP>1</SP> mounted in a single retaining ring. Lateral displacement of the disc 17 with respect to the housing 19 is limited by a vertical pin 47 which is attached to a mounting plate 48 secured to the disc 17 and is confined within a locking ring 49 formed on a projection from the housing 19, so that the edge of the disc cannot strike the housing. The tension in the spring 40 is adjusted so that the disc 17 is returned automatically to the central position within its housing 19 when the device is lowered out of engagement with the end of a lamp. The raising and lowering of the sealing device is effected by a piston 24 which is guided vertically within the lower end of the fixed sleeve 22 and acts upon the lower end of the 'rod 20 through an interposed spring 23. The centring device that engages the lower end of the lamp tube when the sealing device is lifted comprises a series of fingers 14<SP>1</SP> each provided with a small heating-jet 44 located below it to raise its temperature to approximately that of the tubular envelope when the latter emerges from an annular oven, the jets being supplied through a ring 45 mounted below a centrally apertured plate 31 and fed through an inlet tube 46. The central portion of the plate 31 is in the form of an inverted funnel to guide the sealing-flames from burners 11, 12 on to the lower end of the exhausting tube. In some instances, e.g. for work of less refinement, the ball bearings may be dispensed with and the kind of operation described obtained by using two flat discs, one bearing against the other.

Filed: 1960-03-10
Abstract: 931,287. Controlling road vehicle height; oleo-pneumatic suspension. SOC. D'ETUDES ET D'APPLICATIONS INDUSTRIELLES COMMERCIALS ET IMMOBILLIERES INTERTECHNIQUE. March 10, 1960 [March 11, 1959], No. 8449/60. Classes 108(2) and (3). A vehicle oleo-pneumatic suspension system, which has an annular chamber 24, located in the or each load carrying damper unit A, surrounding the piston-rod 10 and below the piston 2 each such chamber 24 being in communication with a low pressure oil tank 46 from which a pump 44 returns the oil to the suspension device, is characterized in that the or each chamber 24 communicates with a fluid volume compensating chamber d through a passageway of sufficient cross-section to avoid creation of back pressure on the piston during suspension movements. In the embodiment each annular chamber 24 communicates with compensating chamber d through a port 23, concentric annular chamber 6 and duct 53 each of cross-section approximately one-third or onequarter that of the chamber 24. The oil return pipe 54 to tank 46 is of smaller section. Engine camshaft driven pump 44 sucks oil through restriction 62 and delivers it through pipe 48 with pressure fluctuation damper e, and non- return valve 50, to the head of unit A from which it passes through opposed spring controlled damping valves into the upper cylinder chamber 25 whence it flows through piston height regulating hole 22 in the cylinder wall back to the tank 46. Hole 22 will pass the whole output of pump 44 and is preferably the same size as restriction 62 which limits the pump output at high pressure engine speeds. The volume compensating chamber d has a volume of four times the combined volume of the chambers 24 and contains a flexible diaphragm 58 to allow oil to flow in and out freely. In alternatives the hole 22 is connected directly with the oil tank or the chamber 24 extends directly into a tank or chamber bounded by a resilient diaphragm concentric with the cylinder.

Title: Improvements in rear sight mechanism for small-arms
IPC: F41A19/32
Filed: 1928-03-20
Abstract: 291,782. Pedersen, J. D. June 9, 1927, [Convention date]. Sights.-A rear sight for rifles comprises a vertically adjustable range slide 171 carrying a transversely adjustable windage slide 173, in which is the sight aperture 174. The vertical slide 171 is mounted in grooves on a part of the receiver 2 of the gun, and is attached to a stem 191, which rests over a spring plunger 196 in the stock 1. This spring takes up any backlash in the adjusting gear of the vertical slide, which gear comprises a rack 183 attached to the receiver and a worm 180 rotatable on a hollow spindle 181 on the slide. The hollow spindle 181 is clutched to the worm 180 by a toothed catch 188 under the action of a spring 190; and a lug 193<1> on the worm limits the rotation of the worm to a little less than 180. The serrations of the catch correspond to the divisions of a scale which is marked on the worm and moves opposite to a zero line marked on the slide. When the spindle 181 is pressed down against the spring, the catch may be disengaged and shifted to a new position, and the lug 193<1> is no longer operative and the worm can be rotated indefinitely until the vertical slide is detached. The spindle 181 and the stem 191 are attached to the slide by bayonet-like joints, which facilitate assembling and disassembling. The rack 183 is adjustably screwed to the receiver 2 at 186, enabling the vertical slide to be raised or lowered slightly without affecting the zero of the scale of the worm 180. The rack 183, after adjustment, is clamped by a screw 187. The vertical slide may move slightly obliquely to compensate for bullet drift. The windage side 173 is adjusted by a screw 176 with a milled head 177 detachably secured by a. spring catch 179.

IPC: F23H9/02
Filed: 1928-03-22
Abstract: 300,862. Metropolitan-Vickers Electrical Co., Ltd., (Westinghouse Electric & Manufacturing Co.). March 22, 1928. Rotary conveyers.-In a furnace through which charges are conveyed on supports adapted to be tilted when they arrive opposite a discharge opening, motors driving the conveyer and the tilting means are inter-connected so that they control each other's operation, and only function alternately. As shown, an electrically-heated annular furnace 14, having a discharge-shoot 15 leading to a quenching-bath 75, is provided with a conveyer comprising tables 25 carried by pillars 24 projecting upwardly from a wheel 18 which is rotated on roller-bearings 23 from an electric motor 37 through rack and pinion and worm gearing 31 - - 36. Hinged to the outer edge of each table 25 is a charge support 27 which projects inwardly for engagement by the inturned end 41 of a lifting-rod 38 which carries at its upper end a roller 83 engaging in a cam groove in a cylinder 43 rotated through worm gearing 44 by a second motor 42. The cam groove is so formed that each support 27 is first raised quickly, then maintained in the tilted position for a predetermined time, and finally lowered slowly to allow time for charging a fresh support before the motor 37 is re-started. The shaft 19, which is secured to the hub of the wheel 18, carries at its upper end a commutatormember 46 having radial projections 48 separated by insulation 50, the upper surface and the rim portion of the member 46 being engaged by brushes 51, 54 respectively. As shown in the circuit-diagram, Fig. 4, the operation of the motors 37, 42 is controlled by the respective electro-magnetic switches 61, 69, the former being actuated by a switch 65 constituted by a fixed contact 72 and a member 73 carried on an arm 74 secured to the 'lifting-rod 38. In operation, with the motor 37 running, when the brush 54 contacts with one of the projections 48 the coil 56 is energized and the switch 69 closes to start the motor 42, and so raise the rod 38. This movement breaks the contacts 72, 73 to open the switch 61 and so cut out the conveyer motor 37. As shown in Fig. 5, the furnace wall, adjacent the discharge passage 15, is formed with a projection 76 having an inclined upper face 77 which, by engagement with the outer end 78 of the support 27, positively returns the latter to the horizontal position.

Title: Improvements in or relating to contact photographic printing apparatus
IPC: G03B27/16
Filed: 1942-06-26
Abstract: 557,399. Photographic contact printing apparatus. KODAK, Ltd., and PITT, F. H. G. June 26, 1942, No. 8850. [Class 98 (ii)] In order to control exposures on variablecontrast paper coated with two or more emulsions of different colour sensitivity, the apparatus employs differently coloured filters between the printing zone and printing lamps which are connected in an electric circuit so arranged that an adjustment of a current-regulating device therein, the current in a lamp associated with a filter of one colour is increased, while that in a lamp associated with a filter of a different colour is decreased. In the apparatus shown, a casing 1, Fig. 1, has a glass support 2 for the negative and printing paper, a pressure platen 3 and a diffusing screen 4. Lamps 9 are disposed below the four corners of a frame 5 supporting four colour filters, which may be yellow and blue, alternating round the centre of the frame. Heatresisting glass screens 11 are placed between the lamps and filters. An electric resistance 12 is wired to a series of contacts on a control panel 13 with an adjusting knob 14. A pilot lamp 21 is mounted at the centre of the filter frame 5. The circuit arrangement is shown in Fig. 3, and includes a main switch 22 and a switch 23 operated on closing the platen 3. When the adjusting arm 17 is (a) on contact 20, the pilot lamp 21 is in circuit; (b) on contact 15, the arm 17 breaks the spring contact between 20 and A, and the yellow filter lamps only are energized when the platen closes switch 23 ; (c) on contact A, the spring contact between 20 and A is re-established and the energized yellow filter lamps are weakly supplemented by the blue filter lamps energized through the whole of the resistance 12; and on contacts B, C, D the resistance 12 is distributed between the two lamp circuits so that the yellow filter lamp intensity decreases while that of the blue filter lamps increases in successive steps. If desired, a spring coupling similar to 15 may be provided at the D-end of the contact series so that a printing light wholly blue may be obtained. Reference is made to apparatus in which shutters are used to vary the light passed through the respective filters. Specification 506,727 also is referred to.

Abstract: 677,028. Weighing-apparatus. SARTORIUS-WERKE, AKT.-GES. April 11, 1950, No. 8868/50. Class 143 The knife edges of a precision balance are relieved by vertical movement of a lower carrier 11, Figs, 1 and 4, which, by means of rods 13, lifts the beam 6 off its fulcrum block 4 and, by means of rods 12, swings a pair of upper carriers 15 about pivots 17 so lifting pan suspension blocks 8. During lifting the upper carriers 15 each support the associated block 8 on the conical tips of two rods 20 spaced transversely of the beam, one tip engaging a V bearing whilst the other engages a flat bearing surface, thus, since the pivots 17 allow universal movement, the upper carriers are self aligning. Springs 21 secured to the column 1 bear on the carriers and maintain them in engagement with rods 12 and pivots 17. The amplified movement of the rods 20 ensures that the blocks 8 are separated from their knife edges before the fulcrum knife edge is relieved. In a modification, Fig. 5, each pair of rods 12 are replaced by pairs of rods 12a, 12b which are interconnected by a block 23 secured to rods 12b and pivoted to rods 12a.
