Abstract: 1,105,750. Rectifying. ENGLISH ELECTRIC CO. Ltd. 17 Dec., 1965 [22 Dec., 1964], No. 52061/64. Heading H2F. In a rectifying arrangement, as shown a polyphase bridge of controllable rectifiers 13R, 13Y, 13B, 14R, 14Y, 14B, auxiliary commutating rectifiers 18, 19, and capacitors 20 are provided to shut-off a conducting rectifier before natural commutation. Thus, both initiation and extinction of conduction are provided to allow for control of both output voltage and power factor. If, for example, the conducting period is arranged to be symmetrical with respect to the maximum voltage in a half wave, then a power factor of unity obtains. Varying the width of this period varies the mean output voltage. Displacing the conducting period forwards within the half cycle gives a leading power factor, and displacing it backwards a lagging power factor. As shown, diodes 15, 16 are provided to complete a current path back to the neutral point of N of transformer 10, as an alternative to a path through two main rectifiers 13, 14. A sequence of operations for the Red phase is as follows: With R negative rectifier 14R is fired and a path is completed through 14R, load 12 and diode 15 and/or either or both of rectifiers 13Y, 13B. At the end of the desired period 19R is fired discharging a capacitor 20 (previously charged with terminal 20A positive) to shut off Rectifier 19R continues to conduct until capacitor 20 is again charged with terminal 20B now positive. Subsequently, during the next half cycle when R is positive, rectifier 13R is fired and current flows through 13R, load 12 and diode 16 and/or either or both rectifiers 14Y, 14B. At the end of the desired period 18R conducts to discharge capacitor 20 through rectifier 13R to shut it off. A similar sequence applies to the yellow and blue phases.

A ship 1 has underwater openings 3 along both sides below the waterline 2 and means for exhausting air through the openings. The dimensions and number of the openings and the output of the exhausting air are such that air can be blown as bubbles 4 through the openings at a rate sufficient to cause upwardly directed flows of water along each side of the ship which create ridges 5 of water on the water surface along the sides of the ship and thus generate water flows which move sideways out from the sides. In the embodiment shown the openings are provided in the bow part of the ship. Blowing of the air through the openings at different pressures on each side can be used as an auxiliary method of steering the ship.

Abstract: 1,237,020. Vehicle power steering; steering columns. FORD MOTOR CO. Ltd. 3 Nov., 1969 [11 Dec., 1968], No. 53753/69. Heading B7H. A vehicle steering system comprises a steering gear (20) (Fig. 1, not shown), a shaft 12 connected to said gear and constructed for rotation by a driver and a spring device 22 connected to said shaft and exerting a spring force tending to retain said shaft in a position corresponding to a " straight-ahead " position of vehicle wheels, the spring device 22 comprising a spirallywound leaf spring 36 having one end secured to a steering column assembly and means connecting the other end of the spring to the shaft 12. The spring device comprises a housing 24 secured to the steering column assembly and rotatably supporting a shaft 32 one end of which is slotted, as at 40, and locates an end 38 of the spring 36 whose other end is fixed as by riveting 44 to a housing 42 for the spring. Connected to the other end of shaft 32 is a spool 34 around which is wrapped a flexible cable 52 such that end portions 54, 56 of the cable issue from the same side of the spool (Fig. 3). The end portions 54, 56 are secured to steering shaft 12 such that in the " straight-ahead " position of the vehicle wheels the bisector of the angle defined by portions 54, 56 extends through the centre of shaft 12. The steering gear (20) is constructed to have minimum reaction torque, and the steering effort of the system is a function of steering angle. The steering gear (20) may be of the type employing a torsion-bar coupling. As the steering wheel is rotated from its position corresponding to the " straight-ahead " position of the vehicle wheels, the spring 36 is extended and causes steering effort to increase rapidly giving positive centre feel. Since, however, the torsional rate of the spring drops to approx. zero at one revolution of the steering shaft from the " straight-ahead " position almost no increase in steering effort occurs as the wheels approach full lock.

Abstract: 1411584 Splicing webs HAUNI-WERKE KORBER & CO KG 6 Dec 1972 [17 Dec 1971] 56329/72 Heading B8R In a method of and apparatus for wrapping tobacco rods for cigarettes &c., an expiring wrapping web 11 is spliced to a replacement web 18, and the rod wrapped with the spliced portion is rejected. On near expiry of the expiring web reel (12), Fig. 1 (not shown), a light sensor (19) actuates an electromagnet 61 which draws the expiring web 11 into contact with a friction roller 52. The replacement web 18, previously clamped on to the periphery of a drum 43 by a clamp 47, is thus accelerated up to a speed less than that of the expiring web, the roller 52 being in driving connection with the drum. The roller 52 also drives a splicing drum 78, at a speed equal to that of the expiring web 11, and a control drum 107. The drum 107 comprises control discs 107a, 107b, 107c, having cams which actuate electric switches 109a, 109b, 109c respectively in a control circuit, Fig. 4 (not shown). Initially, switch 109c actuates an electromagnet 91 which causes a carrier 82 to pivot upwardly bringing a splicing drum 42, the web 18, a two sided adhesive strip 62, the web 11 and the splicing drum 78 into contact thereby effecting a splice between the webs. At the same time, a roller 89 on the carrier operates a cutter 111 which cuts the expring web 11. Additionally, a catch means is released allowing a carrier plate 63 to move from its illustrated position, for reception of a new adhesive strip 62. The leading end of the replacement web upstream of the splice is cut off by a fixed knife 112 as the web turns about a guide roller 38. The switch 109b is actuated to start a blower (32) at the precise moment a rod containing the splice is passing thereby removing it from further treatment. Switch 109a then de-energizes the electromagnet 61 and may actuate a brake for the roller 52.
