Abstract: 1,255,882. Fancy yarns. SOC. RHODIACETA. 21 Nov., 1969 [22 Nov., 1968], No. 57228/69. Headings D1F and D1W. A yarn comprises as the sole constituents 1 to 5 thermoplastic continuous filaments of gauge above 5 dtex and having a spiral crimp and/or residual twist torque, each filament having a cross-section which is essentially oval except that one side is concave or substantially flat, and which varies slightly along the length of the filament. The filaments are preferably of polyamide or polyester material. The process for making the yarn comprises the steps of heating a twisted yarn, which has been obtained by giving an initial doubling or assembling twist to two or more synthetic thermoplastic continuous filaments 1 of gauge above 5 dtex, or to two or more yarns 17, 18 each comprising 2-5 such filaments, to a temperature permitting setting and deformation of the filaments without causing individual filaments to stick together, blocking the twist at a definite point i.e. feed rolls 4 or 28, separating the individual filaments or yarns at a point close to where they leave the heating zone, cooling the separated filaments or yarns, and winding them up. The filaments or yarns may be stretched prior to being twisted, and the point of draw may be localised by a snubbing pin 26. The degree of stretch and/or the degree of twist may be varied with time. The separated filaments or yarns may be relaxed with the accompaniment of heat. The apparatus may be arranged such that either a single filament or yarn is supplied from a package by over end yarn feed, or one or more filaments or yarns are supplied from a package 2 by unrolling, or two filaments or yarns are supplied by over end yarn feed in opposite directions as from packages 19, 20. In the case of a single filament or yarn being supplied over end means are also provided for controlling the degree of twist to compensate for the twist imparted by such feed. Such means may comprise a movable spindle having at least two arms arranged symmetrically about the spindle and provided at their free ends with a passage for the yarn, the spindle being provided with means e.g. a magnetic element, for exerting a return torque in opposition to the twist torque.

Patent GB-1345329-A (GB)
Title: Automobile guidance system
IPC: G05D1/02
Filed: 1970-12-28
Abstract: 1345329 Controlling vehicles MINNESOTA MINING & MFG CO 28 Dec 1970 61387/70 Heading B7H [Also in Divisions G3 and G4] In a system for controlling vehicles travelling on a roadway, the roadway is prepared by applying a stripe of magnetizable material down the centre. The stripe is formed from a magnetizable paint comprising ferromagnetic oxide particles or iron filings dispersed in a paint vehicle that includes an organic polymeric film-forming binder material dissolved in a volatile solvent. A stripe may contain 30-40% of magnetizable particles, the particle ratio decreasing with stripe thickness which is in the range of 10-30 mils. It is stated that the stripe can be laid down in a channel in the roadway. Alternatively, the stripe can be preformed or made from a metal foil. The magnetic stripe is programmed by a vehicle carrying an electromagnet having a winding which is pulsed at constant rate to induce spaced magnetized areas having on the stripe a magnetic surface induction of at least 2 gauss. Alternatively, the electromagnet is energized to induce a sinusoidally varying flux in the stripe. A vehicle is equipped to follow the programmed stripe with a flux-sensing device that can be lowered to within 8 inches of a smooth roadway. The device includes two flux-sensors laterally spaced for steering control each of which comprises two vanes of ferromagnetic material connected by a narrow portion whereon a conductive coil is wrapped. The speed of the vehicle along the road is controlled, as shown, by a device 33 responsive to the output of amplifiers 51, 52, 53 connected to flux sensors 26, 27. The device 33 comprises a synchronous motor 35, energized by the mixing amplifier 53 at the frequency derived from the stripe flux-pattern, and a synchronous motor 34 energized from an electric tuning fork. A difference in the speeds of the motors causes the stator of motor 35 to rotate and move a throttle 46 of the vehicle through a lever 44 so as to tend to maintain the road speed at the sensed value. When the vehicle first enters a striped section of roadway at the control speed the lever 44 moves away from a stop 47 to operate a range light 54 through a switch 47; the driver than switches on the automatic guidance system. This is effected by depression of a push-button 58 which energizes an electromagnetic coupling 65, to connect the device 33 to the throttle 46, and external lights 67, 68 to indicate to other vehicles that the vehicle is under automatic control. Power steering is effected by the outputs of amplifiers 51, 52 energizing power steering valves 49, 50. The vehicle is taken out of automatic control be depression of brake, accelerator pedal or movement of steering wheel to open one of switches 60-62. A system malfunction, such as the lever 44 operating switch 48 causes the dashboard light to darken, and, through a thermal-flasher 73, energize a tail light 74, a "take-over control" light 75 and a warning buzzer 76.

Patent GB-760381-A (GB)
Abstract: 760,381. Calculating-apparatus. OLIVETTI & CIE SOC. PER AZIONI, ING. C. Nov. 16, 1954 [Nov. 17, 1953], No. 33116/54. Class 106 (1). In a calculating machine having a selectively settable indexing mechanism, amount-representing elements differentially settable under the control of the indexing mechanism, and travelling means carrying either the indexing mechanism or the elements, a device is provided to sense the elements from the highest order downwards and to arrest the travelling means in a position corresponding to the highest significant digit in the amount represented by the elements. In the machine described, differential actuators, normally settable under the control of a laterally movable pin-carriage, may also be positioned in accordance with a dividend registered by a totalizer, and the sensing device properly positions the pin-carriage, on which is set the divisor, relative to the totalizer, for a division operation. On depression of a key 53, a slide 68 is operated to initiate a machine cycle and a bar 41 is rocked so that when it is moved to the left by a cam 46, its end 48 engages a stud 36 in a lever 32. A pawl 31 carried by the latter engages a rack 28 on a slide 24 which is thus urged to the right. A sensing plate 17 is carried by pivots 21, 211 in the slide 24 and is urged upwardly by a spring 27, but such movement is prevented by lugs 19 of the plate which move sequentially under the lower surfaces 15 of the highest order actuators 12 if these are in zero position. At this time, the actuators are positioned in accordance with the total previously standing on a totalizer 104 since depression of the key 53 also operated a sub-total control slide 73. When however a lug 19 moves beneath the actuator of the highest significant order, the plate 17 rocks upwardly, the lug 19 of the next higher order entering a recess 16 of the next higher actuator and so preventing further forward movement of the plate 17. At the end of the sub-total cycle, the key 53 is restored and a pawl 54 disengages a latch 59 to allow a lever 60 to rock a bail 9 so that an arm 8 thereof releases the pin-carriage for lateral movement. The carriage is stopped with its highest order aligned with the highest significant order of the totalizer by the engagement of an extension 4 with a lug 19. On such engagement, the plate 17 is moved laterally on its pivots 21, 211 just sufficient to rock a lever 74 and release a lever 76 which operates the slide 68 through a slide 117 so as to initiate a further cycle during which the levers 60, 32 and the slide 24 are restored. The lever 76 may initiate a division operation or a sub-total operation in which the amount registered in the totalizer is reset into the pin-carriage. The sensing device may move transversely of the machine and co-operate with apertures in the actuators which are in its path when the actuators are in their zero positions.
