Title: Improved electric incandescent lamps
IPC: H01K1/50
Filed: 1957-01-15
Abstract: 821,465. Electric incandescent lamps. UNION CARBIDE CORPORATION. Jan. 15, 1957 [Jan. 16, 1956], No. 1443/57. Drawings to Specification. Class 39(2) An electric incandescent lamp has a filament consisting essentially of tantalumcarbide in an atmosphere or gaseous filling comprising, at operating temperatures, a halogen, hydrogen and vaporized carbon, said atmosphere being substantially free of oxygen. The gaseous pressure within the bulb or envelope during operation is maintained at, or near, the highest level that the bulb can withstand, an inert gas such as argon being included to attain such pressure if necessary. In an example a sealed beam automobile lamp has a tantalum carbide filament in an atmosphere.. at operating temperature, of hydrogen, chlorine, and volatilized carbon, together with argon. The components of the atmosphere may be provided by introducing hexachlorobenzene before the bulb is sealed. The filament may be carried between tantalum carbide leads which are, in turn, attached to nickel leading-in wires. The envelope, which is of about 270 c.c. capacity, has a filling comprising about 2.75 m.g. hexachlorobenzene and 20 c.c. of hydrogen at atmospheric pressure and room temperature, along with sufficient argon to bring the total pressure within the bulb at least to slightly less than one atmosphere. The inner surface of the bulb is preferably provided with a protective coating, e.g. by evaporating calcium fluoride upon it before the lamp is assembled. The filament may be straight, coiled, crimped or otherwise shaped and may be converted from tantalum to tantalum carbide, after the bulb has been assembled, by baking the bulb at about 300‹C. for about 15 minutes, with sufficient current passing through the filament to yield a filament temperature of about 3100‹C. Alternative materials for providing the necessary atmosphere comprise ethylenediamine hydrochloride oimethylamine hydrochloride, or a combination of materials such as ethylene or another hydrocarbon and hydrogen chloride gas, or a combination of hydrogen chlorine, and a volatile hydrocarbon. Other inert gases, such as xenon or krypton may be used instead of argon. The parts of the leads within the bulb may be rods of carbon, tungsten, or gold plated nickel.

Abstract: 858,142. Wrapping-machines. PEMBROKE CARTON & PRINTING CO. Ltd., and COOK, J. A. Jan. 15, 1958 [Jan. 15, 1957], No. 1525/57. Class 94(1). [Also in Group XVI] In a machine for wrapping a paper strip round a batch of collapsed cartons &c., feed of the strip is initiated by movement of the batch into the feed channel along which it is forwarded to the wrapping position. Batches 13 are fed over a guide 17 to an intermittently rotating wheel 16 with adjustable pockets which deposits them on the base 12 of the feed channel to be forwarded by a reciprocating pusher 27. Each batch may be secured by a single strip, the ends of which overlap and are adhesively joined, but in the embodiment described a short length of additional strip overlaps and joins the ends of the main strip. The main strip 31 has a heat responsive sealing surface and is fed downwards by rollers 35, 36, profiled to bend it to V section, the roller 35 being rotated through gears 38, 39 and pawl and ratchet mechanism, by vertical movement of a rack 44 under the influence of a weight 45. The rack 44 abuts at its lower end an arm 46 maintained in an upper position by a trip lever 25 engaging the end 51 of a lever 49. When a batch 13 is deposited on the base 12, it depresses a lever 18 which through linkage 21, 24 moves the lever 25 permitting the arm 46 and thus the rack to descend. The descent of the rack feeds the strip 31. As the strip 31 descends it passes adjacent the end of the second strip 61 and at the end of its travel a heater 60 seals it to the strip 61 and a cutter 53 severs it. It is engaged by the advancing batch and wrapped round three sides of it, a cutter 63 severing the strip 61. A vertically reciprocating finger 69 folds one end of the strip about the batch and a combined heater and folder 77 descends to fold in the other end with its sealing strip and secure the latter to the first end. A cam 52 raises the arm 46 and rack 44 and permits the trip lever 25 to reset.

Title: Improvements in or relating to shock absorbing struts
IPC: B64C25/60
Filed: 1945-01-22
Abstract: 589,674. Shock-absorbers. BENDIX AVIATION CORPORATION. Jan. 22, 1945, No. 1716. Convention date, Feb. 5, 1944. [Class 108 (iii)] In a shock strut for aircraft comprising two telescopic cylindrical parts 12, 14 adapted to cause a restricted flow of liquid from one chamber 18 to a second chamber 28 during compression of the strut and forming a third chamber 42 which increases and decreases in volume during compression and extension respectively of the strut, the rate of extension is limited by snubbing means consisting of at least one relatively large passage containing a ballvalve 52, which obstructs flow of liquid from the third chamber 42 to the second chamber 28 but permits free flow in the reverse direction, and at least one relatively small flow-restricting passage 56, permanently interconnecting the second and third chambers. As shown, the inner cylinder 14 slides in a bearing 38 at the lower end of the cylinder 12 and carries at its upper end a bearing 36 which incorporates the snubbing means, the bearing 36 having a number of axial passages 46 one or more of which are provided with plugs 58 formed with the restricting passages 56, while the remainder intersect an annular groove 48 communicating through openings 50 with the chamber 28 and are provided with the one-way ball-valves 52. The chamber 18, which is maintained full of liquid, is formed between a rigid diaphragm 16 in the cylinder 14 and a piston 22 on a tube 20 rigid with the outer cylinder 12 so that on compression of 'the strut liquid is forced from the chamber 18 through an orifice 24 in the piston 22, engaged by a metering pin 34 secured to the diaphragm, and through openings 26 in the tube 20 into the annular chamber 28 compressing air in the chamber and tube. Liquid also flows from the chamber 28 through the openings 50, annular groove 48 and passages 46, past the ball-valves 52 into the annular chamber 42. On extension of the strut due to the expansion of the air in the chamber 28 and tube 20, the ball-valves 52.close and flow of liquid from the annular chamber 42 is confined to the passages 56, thus damping the movement which is finally checked by the engagement of a stop 44 on the cylinder 14 with the bearing 38. In a modified form of bearing 36, the groove 48 is dispensed with and the passages 46 extend right through the bearing.
