Title: Improvements in or relating to electric incandescent lamps for vehicle lighting
IPC: H01K9/08
Filed: 1955-02-25
Abstract: 764,944. Electric incandescent lamps. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Feb. 25, 1955 [March 2, 1954], No. 5703/55. Class 39(2) In an electric lamp for use in motor vehicle headlamps, comprising a filament 1 surrounded in part by a screen 2 extending substantially in the axial direction of the lamp, the concave surface of the screen is rendered dull black over the area of the end 12 adjacent the lamp cap and has light-reflecting properties throughout the remaining portion of the concave surface, the object of the black area being to cut out the upwardly inclined rays emanating from a dipped beam when the lamp is associated with a parabolic reflector. The provision of the black area 12 allows the distance "a" between the projection of the end turn 13a of the filament upon the axis X-X of the lamp, and the corresponding projection of the part 14a of the edge of the screen upon the axis to exceed 0.5 mm. thereby reducing the risk of short circuit between the edge of the screen and the oblique end part of the filament which is secured to an adjacent pole wire 4. The other end 5 of the filament is secured to the horizontal lateral edge 6 of the screen below which is secured a second pole wire 3 supporting the screen. The dull black surface is obtained by coating the area 12 with a thin layer of graphite, zirconium, or .zirconium compound, the last mentioned materials also having a "getter" effect. A main filament may be supported between the pole wire 3 and another pole wire (not shown), and positioned so that when the lamp is mounted in a parabolic reflector the main filament is at the focus F.

IPC: G01T7/12
Filed: 1969-02-04
Abstract: 1,216,961. Detecting aerosols. J. H. BURNETT, M. SUCHOMEL, AND W. C. TIPTON. Feb. 4, 1969 [Feb. 5, 1968], No. 5945/69. Heading G1N. [Also in Division G4] In a fire alarm, smoke is detected by an ionization chamber S1 having a pair of electrodes connected to a source of direct current, the voltage of which is stabilized by a Zener diode 1 to give a field strength of about 4 volts per cm. between the electrodes which is said to maximize the effect of smoke on the current through the electrodes. A second ionization chamber S2 having only a small opening to the air compensates for air pressure variations. When, due to the presence of smoke, the electrode current drops below a certain level a normally non-conducting unijunction transistor 9 is turned on to discharge capacitor 5 to trigger an S. C. R. 15 and thereby light lamp L1. Adjustable feedback to the field effect transistor 2 increases sensitivity. Diode 13 protects the circuit from incorrect supply polarity and diode 17 enables incorrect supply polarity to be indicated by lamp L1.

Abstract: 526,810. Conveyer loading-machines for mines &c. MOORE, M. S., and MINING ENGINEERING CO., Ltd. March 23, 1939, No. 6010. [Class 78 (i)] A loading-machine comprising an endless conveyer and a rotating loader bar on each side, is built up of three detachable units, one being a base-plate which carries the motor and transmission gear, the second comprising a member supporting the horizontal run of the scraper conveyer, and the third a member supporting the inclined run of the conveyer. As shown in plan in Fig. 2, the base member A projects laterally on both sides of the other members B and C and one extending portion carries the motor 21 which drives the cross shaft 23 through worm gear. This shaft drives the shafts 17 of the loader bars through bevel gear, and also carries sprockets which drive the chains of the scraper conveyer. An extension of the shaft also carries a clutch 27 and gearing 30 which can be used to drive a windlass or warping drum 28 which travels along the fixed cable 54 to move the whole machine laterally towards the heap as the loading progresses. The rotation of the loader bars picks up the material by means of the fingers 18 and deposits it on the comb 19 whence it falls on to the conveyer and is eventually delivered from the top of the structure to a main carrying-off conveyer. The second member B is supported on two channel irons 33, Fig. 9, which are provided with a saddle 37 straddling the fixed housings of the shafts 17 and also with projections 34 bolted to other projections 35 formed integrally with these housings. The third member C has inwardly projecting flanges 45 bolted to inwardlyprojecting angle irons welded to the channel irons 33.
