Title: Improvements in or relating to a method of and apparatus for welding pen tips to pen nibs and the products resulting therefrom
IPC: B23K11/00
Filed: 1934-12-29
Abstract: 452,861. Welding tips to pen nibs. PFANSTIEHL CHEMICAL CO., Waukegan, Illinois, U.S.A.-(Assignees of Pfanstiehl, C.) Dec. 29, 1934, No. 37290. Convention date, Jan. 13. [Classes 83 (ii) and 83 (iv)] [See also Group XI] In a method of welding a metallic tip to a pen nib the tip is first tacked to the nib, providing poor heat conductivity between tip and nib, and subsequently metal is fused adjacent to the tack whereby the tip is welded to the nib. The nib 10 is secured in a holder 13 having a spring-pressed copper jaw 12, Fig. 4, and a copper ring 26 to position it in the apparati for tacking and arc welding the tip. In the former operation the ring 26 closes contacts 24 to charge a condenser 21 when the nib holder is placed in position in a stand 14, when the nib reaches the hard metal tip 11 resting on the tantalum contact 17 a discharge takes place and the tip is tacked to the nib. The holder with the nib is next placed in the air-cooled stand 43, Fig. 3, for the arc-welding operation. A glass sleeve 30 surrounds the space occupied by the nib and hydrogen is fed in through the pipe 31 to provide a quiescent atmosphere, this hydrogen is ionized by a heated tantalum or like filament 29 which forms one electrode for the arc for welding the tip to the nib, the latter forming the other electrode. In a modification, Fig. 7, two filaments 29 are employed and the arc takes place across these. A D.C. or A.C. current may be used for the welding operation in the latter case a 110 or 220 volt supply is stepped up by the transformer 44, Fig. 7 to 800-1000 volts, a magnetic shunt 47 being provided to prevent a sudden rush of current on establishing the arc. The tungsten filaments are continuously heated by a high amperage low voltage current, for example 30 amperes and 1¢ volts, from the transformer 45, the operation of the arc is controlled by a mercury timing switch. A three-phase arrangement is also described in which three filaments each operating on a different phase are used to produce a larger and hotter arc than in 'the previous arrangement. The Specification as open to inspection under Sect. 91 was directed broadly to welding a tip to a metallic base and described the use of the apparatus for fusing each point of a split-steel pen nib into a small spheroid. This subject-matter does not appear in the Specification as accepted.

Abstract: 1322193 Film reading devices RICOH KK 4 Aug 1970 [22 Sept 1969] 37453/70 Heading G2E In a cine projector, the free end 17a of film roll 17 is automatically extracted from opening 2a of cartridge 2 by a device comprising a stripper pawl 4 pivotable against spring-loading about shafts 18 and 11a to engage the periphery of roll 17 somewhat before a driven endless belt 9 on feeder 10 pivots against gravity about shaft 6a to frictionally engage the periphery and rotate roll 17. Shafts 11a and 6a are driven through one-way ratchet devices 22 and 36 on gears 12 and 16 which are themselves driven by the gear 15 through gear trains as in Fig.3. The film end passes between pawl 4 and belt 9 to the projector gate 44 and there displaces portion 42c of a detector 42. Lever 41 is thereby pivoted on shaft 40 and so rotates bi-furcated lever 37 on shaft 38 to axially move clutch ring 29 and disconnect the drive to gear 15 from pulley 27. Pawl 4 on arm 11 is then spring-retracted, while feeder 10 retracts under gravity. Feeder 10 is rotated about shaft 6a by a frictionslip coupling between the pulley 6 and the beltsupporting plates 5, 32.

Abstract: <PICT:0783713/III/1> In a process for the separation of a gas mixture into its constituents by continuous circulation of the mixture through a tube containing material which causes the various constituents to flow at different rates through the tube, the temperature of the tube is alternately lowered and raise so that some or all of the constituents are alternately condensed and volatilized. A carrier gas, e.g. nitrogen, is pumped from reservoir f through tube a which is immersed in a liquid bath h, the temperature of which may be varied; the gas mixture is introduced at g and separated fractions are examined in cell c by means of an infra-red gas analyser, an infra-red spectrometer, or a mass spectrometer; transmission measurements may be made with ultraviolet, visible, or infra-red radiation, or variations in thermal conductivity may be measured. The tube a may contain activated charcoal for the separation of permanent gases and lower hydrocarbons, or kieselguhr mixed with dinonyl phthalate for less volatile compounds.  Isotopes may be separated when a suitable gaseous or low boiling compound can be prepared.
