Patent GB-1208302-A (GB)
Title: Improvements in or relating to machines for operating upon continuous material
IPC: B65H20/24
Filed: 1967-10-10
Abstract: 1,208,302. Feeding webs. GLOUCESTER ENG. CO. Inc. 10 Oct., 1967 [10 Oct., 1966], No. 46200/67. Heading B8R. Relates to apparatus wherein a web 50 is fed continuously from a supply, and a portion of the web, adjacent to a device 103 intermittently operating on the web, is brought to rest whilst the device 103 is operative. In one construction, Fig. 1, the web 50 passes under a floating roller 44, over a fixed guide roller 8, over driven rollers 4, 6 on a reciprocating carriage 2, between rollers 87, 89 intermittently driven as described below and from thence to the operating device 103. The floating roller 44 operates a potentiometer 120 controlling the speed of a motor 122 which drives a belt 21 driving the rollers 4, 6. The motor 122 also drives a shaft 130 which operates a valve 132 controlling an hydraulic motor 16 so that the motor reciprocates the carriage 2 to cause the part of the web extending towards the operating device 103 to be intermittently brought to rest whilst the device 103 operates thereon. The span of the belt 21 between the rollers 4, 6 is in driving engagement with a sprocket 85 which through a one-way clutch 101 and chains 21<SP>1</SP>, 22<SP>11</SP> drives the feed roller 89 intermittently. A linkage 107 from the roller 89 causes the device 103 to operate when the web beneath it is stationary. The one-way clutch prevents any rearward movement of the web during the period the device 103 is operating. In a second construction, Fig. 2, the carriage 2 is freely movable horizontally and the sprocket 85 is drivingly connected by devices 105 such as the chains 21<SP>1</SP>, 22<SP>11</SP>, Fig. 1, to the feed roller 89<SP>1</SP>. An intermittently-operating rotary hydraulic motor drives a web feed roller 89<SP>1</SP> at a higher speed preferably twice that of the incoming web 50, the motor speed being controlled by a valve 132<SP>1</SP> operated by a cam controlled by the incoming web. Whilst the roller 89<SP>1</SP> is being driven the carriage is moved to the left by the web. The valve 132<SP>1</SP> also operates to reverse the flow of fluid to the motor when the device 103<SP>1</SP> is operating, but reverse rotation of the motor and roller 89<SP>1</SP> is prevented by the one-way clutch 101 at the sprocket 85, so that any reverse movement of the web is prevented and at the same time the carriage is caused to move to the right by the action of the belt 21 in preparation for the next feed of the web past the device 103<SP>1</SP>. Specifications 1,058,883 and 1,058,882 are referred to.

Abstract: 1382517 Transistor switching circuits HONEYWELL Ino 13 Oct 1972 [26 Nov 1971] 47458/72 Heading H3T  In a circuit for connecting an A.C. supply to a load by means of a bilaterally conducting controlled switch 10, the control circuit for the switch comprises: a charging circuit including charge storage means 27; means for providing a pulsating voltage; a first switch 33, 34 controlled by the pulsating voltage to periodically connect the charge storage means to the control electrode of switch 10; and a second switch 35, 40, 41 connected in series with the first, and responsive when the potential on the charge storage means 27 exceeds a predetermined threshold. When switch S is closed, an A.C. input at 16, 17 is rectified by bridge rectifier 21 to produce a steady D.C. across capacitor 27, and a D.C. pulse train at the base of transistor 29. Each pulse switches on transistors 29, 33, 34 to connect the voltage across capacitor 27 to SCR 35, which can only conduct when the breakdown of Zener 40 is reached. Triac 10 therefore cannot be gated on until the voltage across capacitor 27 has built up sufficiently for the triac to conduct over its entire current carrying region.

Abstract: 1,187,905. Fuelling reactors. ATOMIC ENERGY OF CANADA Ltd. 11 Oct., 1968 [16 Oct., 1967], No. 48369/68. Heading G6C. The lower end of a reactor standpipe 27 is normally sealed by a flap valve 15 pivoted at 16 in a body 11 attached to the standpipe. A fuel bundle 19 is lifted into the standpipe by the tip 30 of a tapered snout 29 of the fuelling machine (not shown), during which movement the fuel bundle 19 engages the convex face 21 of the valve 15 so that the latter enters a recess 17 of the body 11, Fig. 3b. Eventually, Fig. 3c, the face 21 of the valve 15 returns under gravity against the snout 29 and on withdrawal of the snout the parts assume the positions shown in Fig. 1. To remove a fuel bundle 19 from the standpipe the snout 29 is raised to the Fig. 3c position and then rotated through 180 degrees, Fig. 4c, so that on withdrawal of the snout the bundle follows and is not retained by the valve. In a modification (Fig. 5, not shown), the snout is not tapered and a retaining member is interposed between the snout and the fuel bundle. After the snout has raised the fuel bundle into the standpipe dogs on the retaining member enter recesses in the standpipe so that on withdrawal of the snout the fuel bundle is retained.

Abstract: 1,120, 967. Measuring aerodynamic conditions electrically. ELLIOTT BROS. (LONDON) Ltd. Nov.2, 1966 [Nov. 16, 1965], No.48730/65. Heading G1N [Also in Division G3] Turbulent or non-turbulent air disturbance around an aircraft in flight is measured by feeding, for example, an indicated air speed signal at I, Fig. 4, to a filter 11 which removes the component representing mean value of the speed to leave higher frequency signals representing the disturbance, these being rectified at 12, and smoothed at 13. The smoothed signal is compared in a function generator 14 with a predetermined rate of change of air speed signal from 15, and when it exceeds this predetermined value (k 1 , Fig. 2 not shown) the function generator 14 operates to reduce the gain of an amplifier 16 in an autopilot control loop according to a preset curve Fig. 2 (not shown). A second disturbance measuring channel may be provided in which a height signal is fed in at I', filtered at 11', rectified at 12', smoothed at 13', and compared with a predetermined vertical speed signal from 15'. When the smoothed signal exceeds the predetermined vertical speed signal, a function generator 14' operates to reduce the gain of a second autopilot control amplifier 19, which is connected in the control loop only if the first function generator 14 is also giving an output. Exceeding of the predetermined values is detected by respective operation of switches 18 and 21 which must both operate in order to close a switch 20 which connects the amplifier 19 into the control loop. A third channel responsive to Mach number Ia and a predetermined Mach rate 15a may be provided, and in this case a third control amplifier 16a is connected in series with the first amplifier 16, so that one or other or both may have their gain modified. A switch 18a, in parallel with switch 18 and operable when the output of smoother 13a exceeds the predetermined Mach rate signal from 15a, ensures that the amplifier 19 is connected in the control circuit only if either the indicated air speed channel (as described above), or the Mach number channel, or both, produce gain-adjusting outputs in addition to the altitude channel.
