Patent GB-766378-A (GB)
Title: Improvements in or relating to voltage stabilising circuits
Inventor: WOLFENDALE ERIC
IPC: G05F3/16
Filed: 1954-08-11
Abstract: 766,378. Automatic voltage regulation. MULLARD RADIO VALVE CO., Ltd. April 26, 1955 [Aug. 11, 1954], No. 23330/54. Class 38 (4). In a D.C. voltage stabilizing network, a junction transistor T1 is in " groundedcollector " connection with its collector-emitter path in series with a load 7 across a D.C. supply 1, 3. The base of T1 is controlled by the emitter output of a second junction transistor T2 of the same conductivity type as T1 and also in "grounded-collector" connection with its base controlled by a reference source 5 of voltage substantially equal to that of the D.C. supply. Since the emitter voltage of T1 follows the base voltage of T2, the voltage across the load 7 is maintained substantially equal to that of the source 5 in spite of fluctuations in supply voltage and load impedance. The current drawn from source 5 is negligible, since the base current of T1 is derived mainly from the supply. In order that control may be retained in the case of small load currents, a resistor 10 provides an alternative path for a reverse base current in T1, and thus prevents the cutting-off of T2 as a result of its high impedance collector-emitter diode connection in the path of such a reverse current. A resistor 12 may be connected across T1 to permit of larger load currents. Specification 752,055 is referred to.

Title: Improvements in clearers for the rollers of textile machinery
IPC: D01H5/64
Filed: 1930-08-02
Abstract: 354,053. Roller underclearers for spinning-frames. FIXE COTTON SPINNERS & DOUBLERS ASSOCIATION, Ltd., and HINDLEY, J., St. James' Square, Manchester. Aug. 2,1930, No. 23341. [Class 120 (ii).] An underclearer for the bottom drawing-rollers of mules, ring frames and flyer frames comprises a series of discs of wool or other material of alternately large and small diameters threaded on to a shaft and arranged just below the roller to be cleared. The clearer is formed of discs a<1>, a<2>, Fig. 1, threaded on to the shaft A<1>, the end discs a<3> being preferably slightly wider than the others. The holes in the centre of the discs are made slightly smaller in diameter than the rod A<1> so that the discs grip the shaft. The clearer is rotated in the reverse direction to the roller or rollers being cleared, and preferably at a slightly greater surface speed, there being a small gap, e.g. one sixteenth of an inch, between the surfaces of the clearer and roller. Various forms of mounting the clearers are described. For a mule one large diameter clearer is applied to the two front bottom rollers, or one large diameter clearer is applied to the front bottom roller and a small diameter clearer to the two back bottom rollers. For the rollers of a ring spinning frame having a four-roller system of high drafting, three clearers may be used, one for the bottom front roller, one for the two middle bottom rollers, and one for the back bottom roller. For a flyer frame in which the roller stand has a variable setting, a large diameter clearer A, Fig. 11, is applied to the front bottom roller C<1>, and a small diameter clearer to the bottom middle and back rollers C<2>, C<3>, the smaller clearer being supported on two inclined faces b<1>, b<2>, so that as the rollers are moved together or apart the clearer will always remain midway between them.

Title: Fuel supply control systems for aircraft gas turbine engines
IPC: H02P23/00
Filed: 1963-06-14
Abstract: 1,016,424. Electric correspondence control systems. R. WOOLISCROFT HAIGH. Sept. 1, 1964 [June 14, 1963], No. 23742/63. Heading G1N. The fuel supply to an aircraft gas turbine engine is controlled by a manually operated lever which at low speeds controls the fuel supply directly and at higher speeds controls the engine speed directly, the speed at which the change-over occurs being independent of altitude, which normally varies the relationship between fuel flow and speed. As shown (Fig. 3), the fuel flow is measured by pick-up 31 and the engine speed by pick-up 24, the latter signal being fed through unit 25 to produce a constant voltage whose frequency is proportional to speed. The manually operated selector lever 18 comprises a movable electrode 23 associated with four fixed electrodes 19-22. Electrode 22 is fed by difference amplifier 29 whose inputs are the actual fuel flow signal from 31 and an idling fuel flow signal preset by potentiometer 27: electrode 21 is fed by difference amplifier 28 whose inputs are the actual fuel flow signal and an intermediate fuel flow signal preset by potentiometer 26, at which control is to be passed over to engine speed: electrode 20 is fed by a frequency discriminator 34 whose inputs are the actual speed signal from 25 and a preset frequency above which control is to be in accordance with speed only: electrode 19 is fed by frequency discriminator 33 whose inputs are the actual speed signal and a preset maximum speed signal. Thus as electrode 23 is moved from facing electrode 22 to facing electrode 19 the engine speed is varied from idling to maximum by the signal on electrode 23 which controls the fuel throttle valve 15 through a servo-link, first in accordance with fuel flow and then in accordance with engine speed, electrode 23 overlapping adjacent fixed electrodes 19-22, as shown in Figs. 4, 5, to produce a smooth speed variation. Auxiliary parameters may be introduced into the servo-link, e.g. at 39.

Abstract: 1,243,962. Rocket launchers. AVIATION SUPPLY, MINISTER OF. 1 July, 1958 [29 July, 1957], No. 24025/57. Heading F3C. In a rocket launcher in which the rocket is supported and guided by two rails, slight longitudinal curvature of the rocket body tends to cause oscillation of the rocket relative to the rails when the convex side of the rocket and the rails are in contact. The oscillations, although of small amplitude may have an angular velocity sufficient to produce large deviations in flight after launching. To eliminate the oscillatory movement on the launching rails, the latter are given a slight upward concave shape such that the rocket, at any position along their length, will make contact with each rail at two points. The concave bearing edges are produced, either by mounting the rails on supports, the heights of which decrease with distance from the ends of the rails or by maintaining the rails straight and chamfering the inner supporting edges, the chamfer being deeper at the centre than at the ends of the rail.
