Title: Improvements in and relating to apparatus for applying getters to leading-in wires of electric lamps and similar devices
IPC: H01K1/54
Filed: 1953-03-02
Abstract: 724,807. Making electric lamps. BRITISH THOMSON-HOUSTON CO., Ltd. March 2, 1953 [Feb. 28, 1952], No. 5741/53. Class .39 (2) In apparatus for applying a getter paste to a leading-in wire of a mount of an electric lamp or similar device, more particularly' for use in conjunction with a mount-making machine, an arm, arranged to be moved to and fro between the work station and an adjacent pool of getter material, is provided with an axially rotatable end portion carrying a laterally extending finger which has a notched end arranged to be dipped into the getter material at the end of one movement and, during the return movement, rotated so that the notched end of the finger is positioned  about a portion of the leading-in wire. In the example, a mount 4 held between jaws 1, 2 of an indexing carrier is provided with two filaments 45, 46 carried by pairs of leading-in wires 43, 44 respectively, and the getter-applying device comprises a pair of notched fingers 22, 23 extending radially from the end 24 of a shaft 12 that is rotatable. axially within a hub 11 secured upon the upper end of a vertical shaft 13. The shaft 12 and its end portion 24 together form an arm 7 that is swung to and fro in a horizontal plane by a cam-operated crank and connecting rod coupled to the lower end of the shaft 13. During the clockwise swing of the arm 7 from the getterapplying station to the getter reservoir 10, a tab 25 extending upwardly from the shaft 12 engages. the underside of a flat arcuate plate 26 and assumes a trailing position by turning the shaft 12 in opposition to a tensioned helical spring 27, so that the fingers 22, 23 occupy a leading position. At the end of the swinging movement of the arm 7 the ends of the fingers 22, 23 . are located above a spoon 8 which is immersed in the getter paste, whereupon the spoon is lifted by the upward reciprocation of a vertical shaft 30 to which it is conected by a U-shaped strap 31, thus applying the getter to the notched ends of the fingers. During the return movement of the arm 7 the tab 25 and fingers 22, 23 retain their angular position relative to the track 26 until the tab passes beyond the end of the track, whereupon the tensioned spring is released and the shaft 12 carrying the fingers rotates through 90 degrees to bring them against the leading-in wires 43, 44. The operation is completed. by a short upward, movement of the shaft 13 under the action of its control cam, whereby the getter-carrying fingers 22, 23 are caused to spread the getter more thinly over the wires 43, 44. The movements of the spoon 8 are such that it is withdrawn from the getter reservoir only for the moment required for the getter to wet the fingers, the constant movement of the spoon serving to stir and agitate the contents of the getter reservoir; further agitation of the getter is provided by a steady stream of air bubbles from a pipe 39. Specification 264,805, [Class 39 (ii], is referred to.

Title: Method of and apparatus for determining counting efficiency in liquid scintillation counting
IPC: G01T1/204
Filed: 1973-02-08
Abstract: 1422721 Liquid scintillator counting apparatus G D SEARLE & CO 8 Feb 1973 [10 Feb 1972] 6221/73 Heading G1A In liquid scintillator counting apparatus, the counting efficiency is calculated, whereby to compensate the measurement of the radio-activity of an isotope sample under analysis for the effects of quenching, by dividing the accumulated pulse amplitude by the number of pulses to determine the average pulse amplitude which is used to obtain the counting efficiency. In the arrangement of Fig. 1, coincidence of pulses is determined at 12 to get A/D converter which delivers digital signals representing pulse amplitudes to register 18 and pulses representing each pair of coincident pulses to register 20. These registers may provide digital displays, but are anyway connected to divider 17, which whenever 18 and 20 are updated takes the quotient and applies the resultant average pulse amplitude to register 19. (Alternatively, this quotient is calculated after predetermined time intervals or counts). The output of 19 is operated on by a function generator 21, having a function of the form of Fig. 3 (not shown), which is obtained empirically on a set of standard samples, or mathematically. Preferably, in the latter case, the function generator comprises a linear amplifier and weighting of the pulses of different amplitudes is carried out in A/D converter, which then includes a pulse height analyzer, each channel of which includes a respective weighting function generator (linear amplifiers of different gains). Whichever method of calculating counting efficiency is used, the output of 21 is applied to compensate the output register 22 which forms the output of the main pulse height analysis channel of the system 12, 13, 14.
