Title: Improvements in or relating to plugs or closures
Inventor: WEST DEREK
IPC: F16J13/08
Filed: 1967-09-28
Abstract: 1,241,802. Stud and socket fastenings. FLIGHT REFUELLING Ltd. 27 Sept., 1968 [28 Sept., 1967; 17 Nov., 1967], Nos. 44267/ 67 and 52495/67. Heading E2B. [Also in Divisions F2 and G6] A plug 3 carrying seals 8 and 9 is locked in a fuel stack pipe of an advanced gascooled reactor, by a plurality of locking struts 15 each of which is pivotally mounted at one end in a groove 12 in the plug and is movable by a cam ring 21 from extracted position to a locking position wherein the other ends of the struts engage in a groove 25 in the pipe so that any force tending to move the plug out of the conduit places the struts under compression. Each strut is provided with a head 19 which engages in a cam track 20 formed by straight and arcuate portions 23, 22 of an annular groove in the caming. In the retracted position of the struts, the strut heads lie in the central region of the straight cam track portions, right hand side of Fig. 1. On rotation of the ring the strut heads are moved into the arcuate portion and are thus extended to the locking position, left hand side of Fig. 1. Reaction pins 48 on the cam ring lift the heads off the cam track in the locked position to prevent the transmission of forces from the struts to the ring in a direction tending to rotate the ring. The plug is provided with a valve 28 which prevents rotation of the cam ring from the locking position until the valve is depressed to equalise pressure on both sides of the plug the enlarged valve stem portion 30 obturating a peg 26 on the cam ring until the valve is depressed. The cam ring is additionally retained in the locked position by levers 42 each of which is centrally pivoted to the cam ring and has a free end engaging a notch in a stop ring 38 secured to the plug so that the cam ring cannot be rotated from the locking position until a grab off the charge machine initially releases the levers from engagement with the stop ring. In an alternative embodiment, Fig. 2 (not shown), the locking struts are extended and retracted by an axially movable cam ring 53 having inclined camming slots 55. The cam ring is locked in the inner most (locking position) until a charge machine grab depresses a valve stem 30 to equalise pressure on both sides of the plug and permit radially inwards movement of a ball 58 from a position obturating movement of the cam ring. An extension sleeve 63 of the plug is additionally locked to a cam ring extension 62 by a pin 65 whose withdrawal is prevented by a padlock 66.

Title: Demodulator
IPC: H03M1/08
Filed: 1971-11-22
Abstract: 1350102 Pulse modulation systems T T FJ€LLBRANT 22 Nov 1971 [23 Nov 1970] 54211/71 Heading H4L A signal (dotted line Fig. 2a) which has been sampled at periodically varying intervals is demodulated by adding to it in circuit 1 a signal 12 representing the missing samples e required to make up a uniformly sampled signal f, and filtering the result at 2. Amplifier 3 produces the output U. If the notional uniform sampling signal shown at f has a period T, the varying sample periods of input a may be for example nT, (n+1)T, nT, &c., so that a generally lower (varying) sample frequency can be used for a given maximum frequency ¢T of the signal being sampled. The missing samples e may be generated in Fig. 1 by applying the demodulated output b to a uniform rate sampler 4 and to a variable rate sampler 5 whose rate varies in the same way as the sample rate of the input a. A subtractor at 6 derives e. The filter 2 may be an analogue or gate-and-store type, and timing for the sampler 4 is controlled either by a clock or by the input signal. Alternatively (Fig. 3, not shown) the output U is fed to one sampler 7 which samples at the missing sample times. In another embodiment (Fig. 4, not shown) a plurality of adding circuit is used, each receiving the input signal a through successive delays (J), and the missing samples each being derived by a filter 2 amplifier 3 and a missing sample generator (7), as in the Fig. 3 embodiment, but in this ease with the filter 2 being connected to the output of the previous adder circuit, or in the case of the first stage, the filter receiving the input signal a at 1. If a digital filter (F, Fig. 5, not shown) is used, the missing samples are generated by a gate circuit (G) operated at appropriate periods.

Title: Device for testing for broken threads in spinning machines
Inventor: GUIDO CARLO
IPC: D01H13/14
Filed: 1965-12-24
Abstract: A carriage carrying a seat for an operator and provided with a feeler bearing against the threads moves alongside a spinning machine; when the feeler encounters a broken thread, the movement of the feeler interrupts the drive of the carriage so that the operator can repair the break.  The carriage may be provided with pneumatic means for cleaning the machine and the shop in which it is used, and may move one machine or more than are simultaneously or necessively.  The feeler may be a spring wire engaging the threads by a curved portion, or a shoe.  It may be caused to bear against the threads by its own weight, being mounted on an inclined ax is or to slide on an inclined guide; or by a spring e.g. of a switch with which it is in contact; or by a pneumatic piston.  The feeler may be mounted so that it can be retracted to avoid the end-posts of the frame, either by means of lazy-tongs Fig. 17 (not shown), or by a rack and pinion arrangement, Figs. 11, 12 (not shown).  The carriage may move on a single rail laid on the floor, Fig. 1, (not shown), or an overhead rail which may carry current for the carriage.  It may be suspended Fig. 14 (not shown), from an overhead carriage guided on rails and carrying the driving motor, the suspension being such that the feeler-carriage tends to swing towards the machine, when a vertically-pivoted runner engages a rail on the machine.  When the runner moves off the rail, e.g. between machines, the carriage tilts to cause a wheel, normally off the ground, to touch the ground and support the carriage.  The carriage may be guided by pulses emitted from a buried cable, in which case the feeler is on the end of a spring-loaded bellcrank Figs. 15 and 16 (not shown).  The carriage may be driven by compressed air from bottles carried by the carriage; in this case the feeler is urged against the threads by a piston which interrupts the supply to the motor when the feeler encounters a broken thread.  A blower may be provided beneath the seat of the operator.  This is connected with outlets one directed on to the shop floor and some directed at various levels of the machine.  The dust &c. thus blown off the floor and machine are collected by suction nozzles connected via a filter connected to the intake side of the blower, Figs. 19, 20 (not shown).
