Abstract: 981,412. Magnetic storage devices. MOTOROLA Inc. Sept. 28, 1962 [Oct. 16, 1961], No. 36930/62. Heading H1T. A transfluxor device having rectangular loop core as described in Specification 981,411, has first and second input windings 12, 13 (Fig. 1), which each link at least one minor aperture (such as 23, 24, 25) in each of the major flux paths defined by major apertures 17 and 18, these input windings 12, 13 passing in the same sense through the same minor aperture, e.g. 23 in one major flux path to provide a gate function and through minor apertures, e.g. 24, 25 in the other major flux path in senses to provide a negation of the gate function and an output winding 14 linking another minor aperture 27, 26 in each major flux path and in which a current is induced in one direction to represent the gate output and in the other direction to represent negation of the gate output. In the AND gate arrangement of Fig. 1, the core is blocked by a current from 31 which saturates it with a clockwise flux passing around the whole core outside the minor apertures and around the major apertures 17, 18 inside the minor apertures. X and Y currents through 12 and 13 then produce opposite effects at aperture 13 which cancel but switch the flux to an anti-clockwise direction round aperture 25 and cause the clockwise flux on the outside of aperture 26 to return inside this aperture and pass in an anticlockwise direction along member 22. The flux at aperture 26 is then switched by a priming current from 34 which produces an output in winding 14 insufficient to switch a succeeding core. The core is then again blocked by a current from 31 and transfers out the information at 26 in the form of a current XY in 14. Other input current combinations #XY, #X#Y produce the same output as X#Y above described. The combination XY however produces information at aperture 27 and an output current XY of the opposite direction to XY in winding 14. The input sources " X " and "Y" may be OR or AND devices as described or may be devices of the kind described in Specification 981,411, which can drive two AND gates if a further output winding is linked to other minor apertures 25, 28 (Fig. 3, not shown). To provide an OR gate instead of input winding 13 an input winding 43 (Fig. 4, not shown), linking apertures 28 and 24 is provided. An EXCLUSIVE OR device may be provided using two input windings both linking apertures 28, 23, 24, 25 (Fig. 5, not shown). A modified AND gate device also described has input windings 52, 53 (Fig. 6), both linking four minor apertures 54, 55, 56, 57 and presents a constant load to the input windings 52, 53.

Abstract: 1,236,653. Crimping yarn. ALGEMENE KUNSTZIJDE UNIE N.W. 2 Aug., 1968 [4 Aug., 1967; 14 Feb., 1968], No. 37067/68. Headings D1F and D1W. A synthetic yarn is drawn and crimped by heating in a process in which the yarn is supplied at constant speed and/or under constant tension, heated then crimped by crimping members providing a zig-zag path for the yarn and having a speed equal to or greater than the yarn supply speed and providing a total angle of contact of the yarn with the crimping members of at least 20 radians. The crimping members can be pins blades, but are preferably intermeshing gear teeth in which the acute angle between the tooth flank and the radius of the pitch circle is less than 15‹. The circular pitch of each gear can be less than 1 mm., the thickness of gear teeth measured along the pitch circle can be less than 0.5 mm., the depth of the teeth can be 0.45-0.95 mm., the working depth of the teeth can be 0.35-0.55 mm. and the teeth can be involute and have a module of 0.2. The crimped yarn can be taken up on a ring twisting spindle in which the spindle speed is varied to maintain the ballon tension constant. In the zone between the crimping members and a wind-up device the yarn can be advanced at a speed 1¢ times the peripheral speed of the crimping members, and in that zone the yarn may not be drawn. Alternatively to twisting, the yarn can be tangled and interlaced by a medium flowing turbulently under pressure. After crimping the yarn can be heated in saturated steam under a tension of less than 0.001 g/denier. The yarn produced, e.g. polyester or polyamide may have an angle between neighbouring sides of the zig-zag of less than 90‹ have a uniform crimp and be up to 15% thinner at the bends of the zig-zag.

Abstract: 1478910 Heart pacemakers MEDCOR INC 23 Aug 1974 [25 Sept 1973] 37186/74 Heading A5R [Also in Division G1] Body organ stimulating apparatus, e.g. a pacemaker, includes a power supply 12 comprising at least two parallel branches containing equal voltage sources 22, 31, and a circuit for automatically substituting a series connection for the parallel connection when the voltage of the parallel connected supply falls to a predetermined value, and for maintaining the power supply voltage equal to the predetermined value. Diodes 24a, 26a, 32a and 34a are reverse biased when cells 24, 26, 32 and 34 are normal, but permit current bypassing of an open-circuited cell, and prevent cell reverse polarization. A reference voltage proportional to the output voltage between terminals 16, 18, is produced across resistor R 1  and applied to the base of transistor Q;, to maintain conduction of Q 1 , and consequently Q 2  and Q 3  non-conducting. When the output voltage falls to a predetermined value, Q 1  becomes less conductive and the voltage at the base of transistor Q 2  rises until Q 2  conducts, thus allowing conduction in Q 3 . Conduction in Q 3  back biases diodes 40 and 44 thus allowing batteries 22, 31 to be connected in series with a variable impedance dependent on the base current of Q 3 . In this mode of operation the output voltage at 16, 18 is stabilised, producing a stabilised pulse rate, Fig. 3 (not shown). The circuit of the demand pacemaker 14 is substantially the same as that disclosed in Specification 1366902. A normally open magnetic reed switch 28a, which may be either bistable or monostable, may be closed by a magnet applied externally of the body. Operation of switch 28a causes transistor 82 to conduct thus locking the pacemaker into the fixed rate mode, with output rate dependent upon the voltage available at terminals 16, 18, and also makes Q, non-conducting thus allowing Q 3  to become saturated, switching the batteries 22, 31 in series. Observation of the pulse rate and/or pulse width of the pacemaker may then be used to monitor the condition of the batteries according to previously determined curves, Fig. 2 (not shown). If it is required to switch the batteries in series while maintaining the demand mode of the pacemaker a conductor 29 may be provided.
