Title: Improvements in or relating to vehicle lamps
IPC: B60Q1/124
Filed: 1928-08-07
Abstract: 295,258. Addor, O. Aug. 5. 1927, [Con. vention date]. Rotary machines.-In a vehicle lamp in which the reflector is swivelled sideways by means of the steering mechanism, the reflector is operated by means of an armature on the axis of the reflector and having a number of radial poles co-operating with a relatively smaller number of stationary electromagnets inserted in an excit. ing circuit by the steering gear, the number of poles not being exactly divisible by the number of electromagnets. In the form shown, a reflector is carried by a ring secured to a vertical rotatable shaft 4 mounted on upper and lower ball bearings. The shaft 4 carries a wheel 5 having on its periphery seventeen armature poles 6 adapted to pass between the limbs of U-shaped cores 8 of four electromagnets 7<a> - - 7<d>. The electromagnets are provided with pivoted pressure pawls 10 adapted to be attracted by the cores 8 against the action of springs and to bear against the rear ends of the armature poles 6 to hold them in the field axis positions. The springs are carried by angle pieces 13 adjustable so as to vary the tension, and the angular position of the pawls may be adjusted by screws 14. The electromagnets are connected to insulated segments on a stationary commutator ring 20 provided with a movable contact 21 carried by a rotatable hollow shaft 22. The shaft 22 is coupled by a clutch 23 to a cord-disc 24 free to turn on a hollow shaft 25. The commutator may be mounted on a dashboard 72, and the cord-disc 24 is connected by a cord 25a with a cord-disc 26 on the steering column. By this means, when the steering column is turned, the electromagnets are successively brought into the circuit of an electric-current supply, the armature pole wheel is turned in steps, and the reflector is turned sidewise in the same direction as the steering wheels. The arrangement and breadth of the commutator segments with respect to the initial point of the control movement, and the distribution of the armature poles, are such that the first movement of the steering gear causes a double movement of the reflector, so that the angular position of the reflector is always in advance of that of the steering wheels to give a good illumination around bends in the road.

Title: Improvements in or relating to winding or like engines
IPC: B66B1/12
Filed: 1934-08-07
Abstract: 440,278. Regulating-gear for preventing overwinding. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and RAY, A., c/o Sneyd Collieries, Ltd., Burslem, Stoke-on-Trent. Aug. 7, 1934, No. 22871. [Class 78 (v)] In winding and like engines provided with overwinder throttle tripping mechanism the reverse lever is adapted to render the tripping mechanism ineffective to prevent opening of the throttle when the said reverse lever has been moved to the position for the return journey, thus allowing reverse power to be applied to prevent an overwind in case of brake failure. The throttle lever 1, pivoted at 2, is connected to the throttle by a link 3 through any known form of tripping mechanism (not shown), and also directly through a link 33 carried by a floating lever 30 held by links 31, 32 to the frame 4 and to the lever 1 respectively. A cam 5 is rotated by the engine through slightly more than 360‹ at each wind and effects oscillation of a pivoted arm 7, from the outer end 10 of which is suspended a floating lever 11. The lower end of the lever 11 is connected by a pin-andslot joint 12 to a rocking arm 13 controlled by the reverse lever rod 15. The middle of the lever 11 is connected by a pin-and-slot joint 18 to a rack 17 guided by rollers 19 and gearing with pinions 20, 21. The pinion 20 carries an abutment 28 which can be rotated to lie against the middle of the lever 30, and the pinion 21 carries a crank arm 23 to which is pivoted a rod 24 having a pin-and-slot joint 25 with the throttle lever 1. In the position shown the cage is at the bottom of the shaft and the driver is unable to move the lever 1. On pulling the rod 15 by the reverse lever (not shown) the arm 13 is brought to the position 16 and the lever 11 is swung about pivot 10 and moves the rack 17 to the left to its midway position. This brings the arm 23 to the position 27 and frees the lever 1, also at the same time setting the abutment 28 against the lever 30 and allowing the lever 1 to open the throttle through link 33. The cam 5 now begins to rotate in an anticlockwise direction, first allowing the arm 7 to fall to a vertical position, and at the end of the " raise " lifting it to the position 9, thus forcing the rack 17 to extreme left and again locking the lever 1 in shut position. The driver can, however, at any time after the cam 5 has contacted with the hanging arm 7 pull his lever into reverse and supply steam &c. to the engine, the rack 17 being brought to the midway location by reversing and allowing the link 33 to be effective.

Title: Improvements in electric lighting control systems
IPC: H05B37/02
Filed: 1951-10-02
Abstract: 712,050. Control systems for lighting systems. WILLIAMS, R. G. Oct. 2, 1951 [Oct. 2, 1950], No. 22887/51. Class 38(4) A stage lighting system comprises a single dimmer 1 for the several light sources R, G, B and a pair of cam-operated microswitches (A, B or C, D or E, F) for each source, the dimmer and the cams being operated by a single control member and the arrangement being such that, for any setting of the control member, one source is energized directly from the supply, another is disconnected from supply and another is energized over the dimmer. A further switch allows a white lamp to be energized from the supply either directly through the dimmer, or through the dimmer and a coloured lamp. The effect of continuous rotation-of the control member is to fade up one lamp to full brightness whilst another is directly connected to the supply and then to connect the first lamp directly to the supply whilst fading down (and eventually de-energizing) the lamp which had previously been directly connected to the supply. The third lamp (previously de-energized) is next faded up, after which it is connnected for direct supply whilst the first lamp is faded down and finally disconnected from supply. The wiper, or other voltage selector, of the dimmer thus runs at three times the speed of the switching cams. A separate switch 9 allows a white lamp W (for producing pastel effects) to be energized from the dimmer, either directly or through a resistor, which is constituted by whichever of the lamps R, G, B is " disconnected " from the supply. In a modified arangement two white lamps may be arranged for series or parallel operation. In another arrangement, the " disconnected " lamp R, G or B is energized through a resistor from the dimmer instead of being completely de-energized, in order to produce a pastel effect with the other two lamps. The control member may be manually operated, or powerdriven through a clutch. The driving motor may operate the control members of a number of similar lighting control units.

Title: An improved heat-resisting machinable alloy for use as electric resistance material for high temperatures as well as for manufacturing details of construction exposed to high temperatures
IPC: C22C38/34
Filed: 1945-09-05
Abstract: A heat resisting machinable alloy, wholly or mainly of the ferritic type having a strongly reduced disposition for grain increase at high temperature, contains 10-40 per cent of chromium, 0.2-2.5 silicon, optionally 0.1-9 per cent of aluminium, with or without one or both of nickel and cobalt and the remainder iron in an amount not less than 49 per cent, the alloy being characterized by a content of fine particles of oxides of strong oxide forming metals in amount between 0.05 and 10 per cent or fine particles of carbides in amount between 0.20 and 10 per cent or oxides and carbides together in amount between 0.1 and 10 per cent.  The oxides used may be those of lithium, beryllium, magnesium, calcium, titanium, vanadium, strontium, zirconium, barium, cerium, tantalum or thorium.  The carbides used may be those of titanium, vanadium, zirconium, molybdenum, niobium, hafmum, tungsten, tantalum or thorium.  The said fine particles may be added in a ready-prepared condition and finely powdered, to the molten alloy or mixed with the alloy in a powder metallurgical process.  Alternatively the basic constituents of the fine particles may be added to an alloy melt in stoichiometric proportions.  Thus oxygen may be added to a melt containing a strong oxide forming element or the addition of oxygen may be followed by addition of the strong oxide forming element.  Oxygen may be added by using a slag rich in oxygen, by blowing in oxygen or by giving the oxygen-containing atmosphere surrounding the melt a higher pressure. The alloys may be used in the form of rod, bar, strip or wire or in the form of details of furnaces, machines or apparatus working at high temperatures.

Abstract: 658,293. Adjustable supports for projector lamps. JEWELL, S. V. Sept. 1, 1948, No. 23038. [Class 75(iii)] [Also in Group XXIV] In a lamp mounting device of the type that is manually adjustable in two directions a base for the lamp is pivoted about a horizontal axis on a rotatable sleeve biassed in one rotative direction by a clock-type spring and the base is pivoted against spring means by an operating rod extending through the sleeve and actuated by a bell crank. A casing 1 having studs 2 whereby it can be secured to a motor car contains a sleeve 3 which is rotatable about a vertical axis and has an enlarged head 6 to which a circular table 7 with a threaded stub 9 for mounting a spotlight is hinged by a pin 8, a spring 17 within the sleeve serving to pull the table downwardly. The table is pivotally adjusted by a Bowden cable 25 extending from the dash-board of the car to a bell-crank 24 pivoted at 23, and a push-rod 20 formed by two telescopic parts 20a, 20b with a light spring 27 urging them apart passes through the sleeve from the bell-crank to a socket member 22 on the table. The sleeve is journalled in a bush 4 secured bv a nut 5 in an aperture in the top of the casing and is rotated against the action of a clock spring 29 by a second Bowden cable 13 connected to a grooved nut 15 screwed to the lower part of the sleeve. A ball-bearing 26 for the sleeve is formed by races in the adjacent faces of the nuts 5, 15. An electric lead 44 extends from a terminal 28 in the wall of the casing through the sleeve 3 where it may be protected by a sheath 31 and through a hole 49 in the table to the interior of the lamp-mounting stub 9. Ingress of dust to the device is prevented by a flexible bellows 45 attached to the circular table 7 and to the top of the sleeve. The sheath of each Bowden cable is held by a nipple 34 screwed into one end of a cylinder 32 and the core 13 of each cable is attached to a plunger 35 in screw thread engagement with a handle 38 journalled in the other end 40 of the cylinder; axial movement of the plunger is limited by a flange 46 thereon abutting the end of the cylinder and a bush 36 in which the plunger slides.
