Title: Supporting latch for lighting fixtures
IPC: F21V17/20
Filed: 1951-06-28
Abstract: 704,016. Lighting fixtures. SYLVANIA ELECTRIC PRODUCTS, Inc. June 28, 1951 [June 30, 1950], No. 15417/51. Class 75 (4) An elongated lighting fixture comprising two end plates 3 has a light-controlling member, such as a louvre 5, 6 supported detachably between the end plates by a latch arrangement which has a latch lever 8 pivotally mounted on the light controlling member and a latch hook 7, normally locked in engagement with one of the end plates 3, pivotally mounted on the latch lever 8, the arrangement being such that during initial pivotal movement of the lever 8 the light controlling member is caused to move relatively to the said one of the end plates 3 into an unlocking position and with the light controlling member held in said unlocking position, subsequent pivotal movement of the lever 8 causes the latch hook 7 to move relatively to the end plate 3 into an unlocked position whereby the light controlling member can be detached from the fitting. As shown the lever 8 is pivoted for clockwise unlocking movement on a pin 11 on a central longitudinal member 5 of the louvre 5, 6 and the latch hook 7, which engages the lower edge of an aperture 9 in the end plate 3 is pivoted on a pin 10 to the lever 8. The latch hook 7 is arranged so that during the final pivotal unlocking movement of the lever 8 it bears against the end plate 3 which acts as a fulcrum to rotate the hook 7 out of engagement with the aperture 9. The louvre 5, 6 may have a latch arrangement at each end.

In an automatic D.C. voltage stabilizer of the series valve type, the series valve is controlled by a cold cathode discharge tube which is responsive to the output voltage of the stabilizer. The anode of the trigger controlled cold cathode discharge tube 11 is supplied from an auxiliary stabilized D.C. source through load resistors 15, 16 shunted by reservoir capacitors 17, 18. The trigger of the tube 11 is connected to a potential divider 20, 21 across the output terminals and resistor 21 is shunted by a capacitor 22. The tube 11 forms a relaxation oscillator, and it is shown that in either of two possible modes of operation the voltage drop across the resistor 16 is proportional to the output voltage error, and the grid of the series valve 1 is controlled accordingly.

Abstract: 544,199. Aircraft undercarriages. ARMSTRONG WHITWORTH AIRCRAFT, Ltd., Sir W. G., MURRAY, C. V., and WATSON, H. R. Oct. 29, 1940, No. 15814. [Class 4] A swivel mounted aircraft landing wheel is frictionally damped against its swivelling movement solely by means the action of which is substantially linearly proportional to the load on it. Applied to an oleoleg, this damping is substantially linearly proportional to the fluid pressure obtaining in the oleoleg. In a leg of the latter type wherein the cylinder 14 of the shock absorber forms part of the mounting of the supporting means of the wheel 11, which comprise a hollow piston 13 with bleed holes 15 fast with a trailing fork 12, the mounting also comprises a spindle 25, slidably splined with the piston, integral at its upper end with a freely mounted disc 26. Fixed friction discs 27, 28 are arranged on either side of the latter and the remaining fluid contained within a flexible space above the disc 28 is filled with the hydraulic bag 30, communication with the space above the piston being effected by a pipe-line 31. In the unloaded condition the wheel is free to swivel, thereby facilitating its retraction into its compartment. Known retraction means are described comprising a breakable radius rod operated by a hydraulic jack. The invention is applied particularly to the front wheel of a tricycle type of landing gear. Specifications 421,223, 530,386, 530,387, and 530,388, are referred to.

Abstract: 1457413 Controlling vehicle headlamps BRITISH LEYLAND UK Ltd 11 June 1974 [3 April 1973] 15814/73 Heading F4R [Also in Division F2] In a self-levelling headlamp system, of the type in which the front and rear suspension movements of a vehicle are transmitted to a mechanical integrator the output signal of which is used to adjust the elevation of the headlamps about a horizontal axis, the integrator comprises two input members in the form of bevel gears 2, 3 rotatable on a fixed axle 4 in response to input signals corresponding to the respective suspension movements and an output member in the form of a bevel pinion 9 meshed with the gears 2, 3 and rotatable in response to relative movement between the gears, the pinion 9 being carried by a member 8 which rotates about the axle 4 in response to any except equal and opposite movements of the gears and the output signal being derived from the rotation of the member 8 through a pivoted link 10. In the illustrated embodiment the member 8 carries two bevel pinions 9 and the input signals are transmitted to the gears 2, 3 by respective cables F, R which are wound around the hub portions 6, 7 of the gears in opposite senses and rotate the gears in opposite directions against the bias of return springs (5, 5<SP>1</SP>, not shown). The output signal is transmitted to the headlamp by a damper T which removes high frequency oscillations and comprises an input plunger 14 connected to the link 10 and having an end portion 15 slidable in a sleeve-shaped piston 17 between centralizing springs 18. The piston 17 is connected to an output plunger 16 and is slidable in an oil filled cylinder 13, bleed grooves (26) extending along the entire length of the outer surface of the piston. The end portion 15 is provided with large apertures (28) so that its movement is not restricted by the oil.

Abstract: 643,625. Spinning and twisting yarns &c. FARRAND, T. H., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. June 16, 1948, No. 16177. '[Class 120(ii)] In the production or treatment of a yarn or filament wherein the yarn &c. is collected continuously on a rotating receiving package, initially non-uniform yarn &c. is collected in a suction tube fitted near the receiving package and beyond it on that side of the package distant from the source of the yarn &c., and the yarn &c., is not brought into contact with the receiving package until stable operating conditions have been attained. As shown, undrawn continuous filament yarn, e.g. of polyethylene terephthalate, from a supply package is fed through a ring traveller 7 to a suction tube 9 and is then passed through feed rollers 1, 2 and around a heated snubbing pin 3. When the apparatus is running smoothly, the yarn is passed three times around a draw roller 4 and idler 5 and through guide 6. A pivoted arm 16 is then moved so that a guide 15 presses the yarn against a notched entraining disc 13 mounted between the receiving bobbin 10 and its seat on the spindle 11. Movement of the arm 16 also causes spindle 11 to be set in motion. The yarn is caught up by the entraining disc and caused to wrap around bobbin 10, and at the same time is brought into contact with a cutting edge mounted on the end of tube 9, and cut. Undrawn yarn sucked down tube 9, which communicates with an induction pump, is collected in a bin. Instead of using a guide 15, the yarn may be moved over to the entraining disc manually, or the suction tube itself may be moved. Instead of using a separate disc 13, the bobbin may have a grooved or projecting edge. A cap spindle, instead of a ring spindle, may be used.
