Abstract: 1,024,025. Digital comparators. LICENTIA PATENT-VERWALTUNGS-G.m.b.H. April 22, 1964 [April 22, 1963 (2)], No. 16662/64. Heading G4M. In an arrangement for comparing for equality and for relative magnitude two multi-digit numbers, the digits of the numbers are arranged in groups, each group corresponding to digits of the same orders in each number, each group receiving inputs from the respective digits of the two numbers to be compared and providing output signals, the output signals for the various groups being combined in a further logical output circuit to produce the required comparison signals. The switching time required to effect a comparison is thus reduced. The switching circuits described comprise diode AND and OR gates and are interconnected by inverter gates comprising transistors, a single transistor being indicated in the figures by a thick black bar and two such transistors in series by a black- and-white bar, the interconnections being such that AND and OR gates are controlled only by stages employing transistors. The Specification describes numerous arrangements for comparing two multi-digit numbers a, b, having binary digits ai, bi, a relation a > b being indicated by P = 1, a < b by N = 1 and a = b by K = 1, with corresponding relations for the individual digits ai, bi and indicators Pi, Ni, Ki. The equality relationship of a group of digits, e.g. digits of orders 3, 4 and 5 is indicated by symbols such as P 5/3 ,   N 5/3 , K 5/3 , which are = 1 according as the numbers a 5 a 4 a 3 , b 5 b 4 b 3  are in the relationship >, <, =. In the circuit shown in Fig. 9 for comparing two 12-digit binary numbers, the digits are arranged in four groups, with three digits in each group, the groups thus corresponding to digit positions 2-0, 5-3, 8-6 and 11-9 respectively, switching circuits S 45 -S 52  providing, for each of the four groups K- and P-type (as defined above) output signals such as K 2/0  and P 2/0 , these signals being applied to further switching circuits S 53 -S 55  which produce the desired output signals P 11/0 , N 11/0 , K 11/0  (and their inverses). In other circuits (Figs. 10-12, not shown) the grouping of the digits and/or the particular auxiliary signals K, P or N developed by the groups differ from the arrangement of Fig. 9 and in further modifications (Figs. 13- 19, not shown) different arrangements are illustrated for forming the final outpur signals from the intermediate signals such as K 2/0 , P 2/0 .

Title: Diameter measuring system for cylindrical objects
IPC: G21C17/06
Filed: 1976-04-26
Abstract: 1535862 Measuring diameters photoelectrically EXXON NUCLEAR CO Inc 26 April 1976 [7 Aug 1975] 16798/76 Heading G1A To determine the diameter of an object it is moved past a light source and detector so that one side of the object is in a known position and the other side obstructs the light beam by an amount depending on the diameter; both the source and detector are temperature compensated. Fig. 5 shows skew rollers 38, 40 which drive a nuclear fuel pellet 12 past source 50 and detector 26. The pellet rotates as it passes the measuring station, so its diameter can be measured at many points; this is not essential, and an ordinary belt conveyer may be used, Figs. 1-3 (not shown). The rollers (or a guide-plate in Figs. 1-3) support the pellet such that one side is in a reference position and the amount of light reaching the detector varies directly with the diameter. The detector comprises two phototransistors 60, 62, of which the former always receives the same amount of light from the source while the amount of light received by the latter varies with the diameter. The phototransistors are connected to respective amplifiers as in Fig. 4, the phototransistor 60 acting as a reference which controls the gain of the measuring channel by means of FET 80. This compensates for temperature effects on the phototransistors. The source is an infrared diode 50, driven by amplifier 54 and transistor 52. A further transistor 58, mounted near the source, controls the amplifier 54 and hence the source current so as to maintain the source output constant when the temperature varies.

Filed: 1939-06-15
Abstract: 530,627. Signalling overpower systems. SANGAMO WESTON, Ltd., GILLIVER, G., TAGG, G. F., and SHOTTER, G. F. June 15, 1939, Nos. 17493 and 26658. [Class 40 (i)] In a remote-control and signalling system wherein signals are transmitted over a threephase power system, the signals are produced by a transformer which is supplied by one phase and causes variation of phase angles and magnitudes of the other two line voltages by generating voltages at about 60 degrees and 120 degrees thereto respectively. The variations may be produced at a point on the high-tension side of the system and can be received at another point on the same side or on the low-tension side. As shown in Figs. 1, 2 and 4, the auxiliary transformer is included in line 3 of the power supply system, the winding 5 being connected across the lines 2, 3 through a reversing switch 6. Under non-signalling conditions a winding 7 is short-circuited by a switch 8 and thus negligible impedance is included in the system. When a signal is transmitted the switch 6 is closed in one or other direction and switch 8 is opened, a voltage being introduced in line 3 in phase with or in opposition to the voltage across 1, 2. Fig. 2 shows the effect on the line voltages when the auxiliary voltage V1.2 is introduced, that across 2, 3 being increased from V23 to V<SP>1</SP>23 and retarded by angle α and that across 1, 3 being reduced to V<SP>1</SP>31 and retarded by #. The receiving arrangement comprises two transformers 9, 10 the primary of 9 including a condenser 12 which normally produces phase opposition of the voltages in the series-connected secondaries. When a signal is transmitted the secondary balance is upset and a voltage is developed to operate a receiving relay which is actuated in one or other direction depending upon the actuation of the reversing switch 6. Receiving arrangements for use on a 4-wire high-low tension network may comprise a star-connected transformer or a 3-phase watthour meter relay, connected between the lines and neutral. When a 4-wire low tension system is supplied from a 3-wire high-tension network the receiving system comprises a two-winding relay, one winding of which is connected in a balanced circuit of impedance or transformers so that normally no current flows through the winding.

Abstract: 418,125. Knitted fabrics. LIEBERKNECHT GES., K., Oberlungwitz, Saxony, Germany. June 15, 1934, No. 17812. Convention date, Aug. 24, 1933. [Class 74 (ii).] Hosiery, with French heel and foot, is produced on flat knitting frames, the leg, the heel portions and the part of the foot preceding the narrowed toe, together with the sole portions, being worked on the legger, whereupon the fabric is transferred to the footer on which the toe is worked. The welt and leg of the stocking are worked on an ordinary legger provided with a device for preventing the pressing of the needles of the instep. At the commencement of the working of the heel the needles of the instep are excluded from the pressing so that the loops remain hanging on the needles. The heel portions are then worked and cast off. The side portion of the foot are then begun by forming a starting course on both sides of the instep, still on the machine, and the needles of the instep are again released for the pressing operation. The foot is then produced up to the commencement of the toe whereupon the fabric is cast off from the legger and transferred to the footer where the toe is worked and the stocking completed.
