Title: Improvements in and relating to electric switching arrangements
IPC: H01H33/66
Filed: 1929-12-10
Abstract: 343,230. Heavy - current switches. INTERNATIONAL GENERAL ELECTRIC CO., Inc., 120, Broadway, New York, U.S.A.-(Assignees of Allgemeine Elektricitõts.Ges.; 2, Friedrich Karl Ufer, Berlin.) Dec. 10, 1929, No. 37856. Convention date, Dec. 22, 1928. [Class 38 (v).] Opening of a main switch 1 shunts the whole current through a vacuum switch 4 and coils 22, 23 in series, the coil 22 removing a spring pawl 17 and releasing a moving contact which is accelerated by the coil 23. Reclosures of switch 1 energizes through contacts 20 a closing coil 18 which raises the movable contact of the vacuum switch to the latched-in position, whereupon a time-lag relay 21 operates to de-energize the coil 18. The fixed contact of the switch 4 comprises a polished disc 9, supported by springs 8 and connected to a number of distributed conducting strands 10, and a contact 11 with an iron core. The movable contact comprises a copper plate 15 on an iron core 14, which in opening attracts the contact 11 until the securing spring of the latter overcomes the magnetic attraction, thereby ensuring a rapid break. The latter expedient causes separation of the contacts at the zero point of an A.C. cycle, thus diminishing arcing. The pawl 17 may, alternatively, be released by the coil 23, thereby dispensing with the coil 22.

Title: Electrical circuit to indicate the difference between two binary code numbers
IPC: G06F7/50
Filed: 1958-11-25
Abstract: 852,388. Digital electrical calculating apparatus. WESTERN ELECTRIC CO. Inc. Nov. 25, 1958 [Dec. 3, 1957], No. 37887/58. Class 106(1). A network for determining the magnitude and sign of the difference between two numbers, one expressed in conventional binary code and the other in reflected binary code, comprises a comparison circuit for each denomination and control means comprising more than two carry leads connecting each comparison circuit other than that associated with the least significant digit position with output means associated with the next less significant digit position. The minuend is entered on leads g A , g B  ... g N  in conventional binary code and the subtrahend on leads b A , b B  ... b N  in reflected binary code. Taking the comparison circuit N-1 as an example the following rules then apply: 1. If the inputs on g N-1  and b N-1  are both zero the AND gates 325, 330 produce no outputs and the positive carry leads 341, 356 and the negative carry leads 122, 123 bear the same signal as was applied to them from the preceding position. 2. If the signal on g N-1  is zero and that on b N-1  is one then both carry leads of one polarity will be energized. All outputs, such as - R N , + R N  of the same polarity in less significant digit positions will be energized so long as all less-significant digits are zero. A less-significant one on a " g " input inhibits one output in its position, over circuit 335 or 385 according to sign. Similarly a less-significant one on a " b " input stops one of the carry signals so preventing an output in that and succeeding digit positions. This carry will be restarted if another one appears on a " b " input in a subsequent position. 3. If the signal on g N-1  is one and on b N-1  is zero two carries of the opposite polarity will be started. These carries are continued through successive positions as long as the " g " inputs are one and the " b inputs are zero. The appearance of a zero " g " input inhibits one output in that position. The appearance of a one " b " input stops one carry and one output in that and all subsequent positions. Another one " b " input restarts the carry. 4. If the signals on both g N-1  and b N-1  are one and no mismatch in an earlier position has occurred there are no outputs and no carries and the reflected binary code input digit on the next " b " terminal is reversed. Output circuit. When a comparison circuit has an output it applies a potential to one or more associated resistors - R N-1 , + R N  +  1 . weighted according to the binary position concerned. There is an additional pair of resistors - R o , + R o  of unit weighting. The resultant currents are accumulated and applied to output terminals prior to conversion to digital form in known manner. Specifications 663,872, 843,723 and 850,503 are referred to.

[Class 83 (iii).] A multiple spindle screw machine having a reciprocable main slide adapted to carry a number of simultaneously operable end working tools is provided with a supplementary slide mounted on the main slide which is automatically given a reduced feed compared with that of the main slide, in a diagonal direction to the main axis, without interference to the operation of the tools of the main slide. A cam-operated multiple tool slide 2 has a bevelled plate 9, Fig. 4, mounted on one face which engages a dovetail groove of a slide 11 ; this slide carries, in diagonal ways in its upper face, another slide 14 for a tool which, in the case shown, is designed for finishing both rails. A cross-piece 17 bolted to the main slide 2 carries a cam bar 20 and is recessed at its ends to take compression springs 171 which bear against the slide 11 and normally force it towards the left, Fig. 3 ; the cam bar 20 fitting between the upper andi ntermediate slides bears against a roller 22 which is secured by a bolt in a slot on the upper slide, adjusting screws 27 enabling the correct setting to be obtained. When the main slide is moved to the left by the lead cam, carrying with it the cross-piece 17 and cam bar 20, the intermediate slide is forced to the left by the compression springs 17<1> until its movement is arrested by a stop c, at this point the tool 15 carried by the top slide is in position for the finishing cut, further movement of the main slide and cam bar causing the latter to bear against the roller 22 and move the tool slide diagonally, thus feeding the tool into the work in a transverse as well as lengthwise direction, a spring 23 housed in the cross slide and bearing against a bracket secured to the slide 11, serving to maintain the idler and cam bar in engagement during the operation. Movement of the main slide to the right after the completion of all the tooling operations retracts the cam bar and thus allows the tool 15 to move away from the work, a stop 18, Fig. 1, fixed to the main slide later engaging with the slide 11 and thereby drawing it clearof the work ; should the slide 11 be drawn back against the effect of the springs 17<1> due to friction between it and the main slide a stop b comes into action and limits the movement.
