Filed: 1968-09-05
Abstract: 1,221,188. Electricity meters. SIEMENS A.G. Sept.5, 1968 [Sept.20, 1967], No.42368/68 Heading G1Q. In an induction electricity meter of the type having a short circuiting loop 1 fitted around the central limb 6 of the voltage electromagnet 6, 9, the loop is so disposed relative to magnetic circuit of the current electromagnet 7, 8 that none of the current flux from this electromagnet (passing to the limb 6) will pass through the loop. The loop is fitted to the shunt 2 which connects the limbs 6, 9 of the voltage electromagnet in such a way that in the area where current flux is coupled into the shunt and thus into the central limb 6, the loop passes over the shunt on the side further from the rotor of the meter (by parts 111, 112). The loop is adjustable transversely along the shunt. The arrangement ensures that when the loop is adjusted asymmetrically relative to the central limb 6, no undesired no-load drive will result, because no e. m.f. will be induced in the loop 1 by the current flux.

Title: Improvements in or relating to digital computers
Inventor: CAMPEAU JOSEPH OVID
IPC: G06F15/78
Filed: 1963-10-30
Abstract: 1,058,066. Digital electric calculating apparatus. LITTON INDUSTRIES Inc. Oct. 30, 1963, No. 42779/63. Heading G4A. A general purpose digital computer is made up of a single static logical storage element (e.g. a flip-flop), a memory device having a relatively short recirculating information storage loop, a second memory device having a longer recirculating storage loop, and a cyclical programme memory, operable in synchronism with the other memories. The invention provides a simple digital computer which may be used in place of a general purpose computer of much greater size and complexity. It is particularly useful where minimum initial cost is important and operational speed is a minor consideration. Two types of apparatus are described; firstly, as an introduction to the complexities of the programming scheme, a desk-type calculator, and, secondly, a general purpose computer, the claims being limited to this latter application. Flip-flops and gating logic circuits are simulated by step-by-step, bit-by-bit elementary logic operations upon bits stored in the common cyclically operable information channels, the memory channels including both multi-digit general purpose programme instruction words and multi-digit general purpose information words which are to be used to carry out the total general purpose calculation. The machine operates without discrimination on both types of digits. As described, circulating registers 30, 40 and 50 are formed from tracks on a magnetic drum; 34, 44 and 54 are " read " dynamicizers and 32, 42 are " write " staticizers. There are 3,000 bit positions in a drum cycle, and the programme register 50 comprises a plurality of parallel tracks extending over a complete drum cycle. The " S " register 30 comprises a regenerative loop of 186 bit positions which therefore circulates 16 times plus 24 cells each drum cycle, and the " R " register 140 comprises a regenerative loop of 2,813 bit positions. Thus, during a major computing cycle of 30 drum cycles the contents of the S and R registers precess relative to the programme register and to each other providing facilities in conjunction with a single digit store 20, for submission of any desired combination of digits extracted from store to the operating circuits 10. Detailed programme schedules are included in the Specification.
