Title: Improvements in or relating to electric arc horns
IPC: H01H9/46
Filed: 1932-06-07
Abstract: 391,998. Arc-rupturing in switches. SHEPHERD, G. R., 2, Norfolk Street, Strand, London.-(Westinghouse Electric & Manufacturing Co. ; East Pittsburg, U.S.A.) June 7, 1932, No. 16109. [Class 38 (v).] In order to direct the arc towards the central portion of the arc horns and prevent it spreading to the underside of the horns, the horns are formed as shown in Fig. 5, of two spaced parallel members 23, 24 joined at their extremity by a cylindrical portion 25. The arc on striking one of the side members as at the point 26, causes the current to divide, one portion flowing to the terminal portion 22 through the adjacent portion of the side member 23 and the other portion flowing through the end portion of the member 23, the cylindrical portion 25 and the side member 24. The interaction of the fluxes of the divided portions of the current with that of the arc itself tends to produce a relatively weaker field strength in the space between the members 23, 24 than on the outside. Thus the arc is caused to travel along the horn on the inner edge of the side members and is directed to the central portion of the cylindrical member 25, where it is extinguished without damage to the surrounding arc shoot.

Abstract: 474,930. Knitting - machines. HEMPHILL CO. June 10, 1936, No. 16240. Convention date, July 11, 1935. [Class 74 (ii)] Needle jacks 4 of a circular machine are provided with removable selecting butts 8 actuated by cams 22 so that the jacks are moved lengthways to bring butts 7 thereon into register with a cam 24 by which the jacks can be rocked. Rocking movement of a jack causes a hook-shaped portion 10 thereon to engage a corresponding hooked portion 11 of the needle. All the jacks 4 are lowered by a cam 26 engaging butts 6 thereon, so that the needles corresponding to the rocked jacks are lowered as at 28 so as either to form tuck stitches or miss stitches. Lowering of the needles by a cam 30 and engagement of the hooked portion 11 with a bevelled portion 35 of the jacks effects separation of the needles and jacks, and the jacks are lowered for reselection by a cam 39. The tricks for the needles and jacks may be constructed of sheet-metal having relatively wide portions 12, 13, 14 seating in grooves in the needle bed. In an alternative form, Fig. 6, the jacks and needles do not have hooked engagement, and the rocking movement of the jacks 41 brings the selected jacks into the path of a raising cam 52.

Filed: 1973-04-05
Abstract: 1427385 Analogue-to-digital-conversion COULTER ELECTRONICS Inc 5 April 1973 [7 April 1972] 16437/73 Heading H3H [Also in Division G1] In a photometer, an electrical evaluation circuit of the type in which the input signal is compared with an exponentially decaying signal to establish a time duration is provided with means for storing a signal dependent on the absorption of a serum blank for use as the starting value for the decaying signal in each of several subsequent measurements. Means may be provided for adjusting the rate of decay of the decaying signal during calibration. The illustrated circuit operates as follows. With a serum blank, and both transistor switches 18, 34 closed, the output signal of the photoresponsive element 10 is amplified at 14 and 22 and stored in capacitor 32, allowance being made by the feedback loop for the voltage drops across various circuit components Then, with a calibration sample, switch 18 is opened and the signal from 10 is compared at 14 with the decaying signal, derived from RC circuit 36, 38, 40 of which capacitor 38 is charged to the voltage stored on 32 by momentarily closing switch 34 under the control of slow clock pulses on lines 70 and 62. During the time interval between initiation of decay and equality being detected at 14, fast clock pulses on line 68 are gated out at 65, the equality being signalled via line 58 to reset flip-flop 60. The cycle is repeated at the slow clock rate. During the calibration process, the resistor 40 is adjusted to get the correct output at 65. The circuit is then ready to measure unknown samples from the same serum blank. Error correction features.-Accuracy of the initial part of the decaying signal is ensured, despite a low pass band of amplifier 14, by RC circuit 42, 44, 72. Drift is compensated by voltage divider 44, 50, the resistors 44, 50 being nearly but not exactly equal. Voltage divider 74, 76 prevents unwanted turn on of transistor 18 during calibration and measurement.
