Title: Improvements in and relating to stabilising and forced rolling apparatus for ships and other unstable objects
IPC: G05D1/08
Filed: 1923-09-18
Abstract: 226,279. Jackson, P. R., (Sperry Gyroscope Co.). Sept. 18, 1923. Rolling motion of ships, controlling. -Apparatus for exerting rolling torques on an unstable craft to reduce or augment the oscillations thereof comprises a travelling weight movable back and forth across the axis of oscillation of the craft and means including a gyroscope or gyroscopes whereby the speed and phase of the motion of the weight are suitably varied. Preferably the track for the weight is a closed one. A heavy car 1, Figs. 1 and 2, is mounted on a circular or oval track 2 and in addition to the lower rails 4 there is an upper guide rail 6 engaged by a double flanged roller 6'. The car is driven by a motor 7 through worm gear 8, 9 and pinion 11 engaging a rack 12. Current for the motor is provided by wires 13 - - 16 and the rails 4 - - 6. For governing the speed and position of the car, a gyroscope 17, Figs. 6 and 10, is held with its spinning axis transverse to the ship by weak springs 20, 21 suitable positive stops being provided. The gyroscope carries a brush 24 which when central contacts at 25, and when non-central an arm 24<1> on the brush 24 contacts with stops 26 or 26'. For bringing the car into proper phase relationship, a series of annular contacts 28 - - 31, Fig. 6, with variable central gaps on the fore and aft line of the ship are provided, these contacts being engaged by trolley wheels 36, 37 carried by the car. The gyroscope contacts operating with the sectors 28 - - 31 control the shunt field 39 of the motor 7 and thus its speed. A setries of contacts 51 - - 55 in combination with a double acting relay 56<1> is embodied in this control. A starting rheostat 70 and a variable resistance 71 for controlling the normal speed of the motor is employed. A brake 73 for the motor is held on by springs when no current fows to the motor and is released by a solenoid 72. A reversing switch 80 enables the apparatus to be used for opposing or augmenting the rolling motion. In a modification, a frame 86 is pivotally mounted on the centre line at 89, 90, Fig. 7, its outer end running on upper and lower circular tracks 91, 92 and its motor 7<1> driving a pinion engaging a circular rack. The car or weight 95<1> is adjustably mounted in the frame, a second motor 100 being geared to a rack 101. The motor 100 is manually or automatically controlled. In the latter case, the motor 100 is controlled from a second gyroscope the contacts for which are relatively wider apart than those of the first, whereby under small rolling action this gyroscope is inoperative, but with larger roll it comes into operation and causes the weight 95<1> to be moved radially in its frame and so provide an additional stabilizing effort.

Filed: 1931-08-20
Abstract: 369,513. R÷ntgen-ray tubes. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN, 13D, Emmasingel, Eindhoven, Holland. Aug. 20, 1931, No. 23474. Convention date, Aug. 28, 1930. [Class 39 (i).] Installations comprising a R÷ntgen-ray tube with an anode moved when in use by an electromagnet field are provided with means independent of the field to prevent the load current being established before the current exciting the field. The anode of a tube 1 is rotated by the field of a coil 3 supplied with 3-phase or other current through a switch 5, the supply to the load transformer 2 also passing through this switch. A switch 6 in the primary circuit of the transformer 2 may be coupled electrically or mechanically to the switch 5 so that the switch 6 cannot be closed unless the switch 5 is closed and that the switch 5 cannot be closed unless the switch 6 is open. To heat up the cathode of the tube without emitting R÷ntgen-rays, a low voltage is initially supplied by the transformer 2 when a resistance 7 is in circuit, this resistance being then short-circuited by a switch 8.

Filed: 1974-05-28
Abstract: 1504519 Continuous winding machines IMPERIAL CHEMICAL INDUSTRIES Ltd 12 May 1975 [28 May 1974] 23508/74 Heading D1J A yarn winding apparatus of the kind comprising at least two bobbin supporting chucks 3, 4 mounted on a rotatable head 11 to enable the bobbins to be brought, in turn, into driving engagement with a drive roll 15 is characterised in that the chucks 3, 4 are mounted on guide rails 7, 8 and 9, 10 that are in a plane perpendicular to the rotatable head axis 19, one set of guide rails 7, 8 being on one side of the axis 19 of the head 11 and the other set of guide rails 9, 10 being on the other side of the axis 19 of the head 11, the rails being long enough to allow associated means for moving the chuck carriers to be capable of moving the chuck carriers to settings in which the maximum package diameter may be greater than the distance between the axis 19 of the head 11 and the nearest surface of the drive roll 15. Pneumatic cylinders 12, 13 may be used to bias the chucks 3, 4 towards the drive roll 15. When a winding operation is complete a member 16 moves the yarn towards a suction tube 17 and a cutter 18. The yarn is cut and the yarn from the supply is taken up by the tube 17. The assembly 11 is then rotated through 180‹ to present the shaft 4 with an empty tube 2 thereon to the winding station. The suction tube 17 then swings to a setting such that the yarn being sucked into it is caught or snagged by the new tube, the yarn catching in a groove 20 in the tube and being severed from the tube 17 by a ring knife 21. The yarn from the supply then tends to move towards the centre of the tube and in doing so engages a delay pin 22 mounted on a pendulum. The yarn bears against this pendulum for a sufficient time for reserve wraps to be wound on the tube. The hold up time can be adjusted by changing the length or weight of the pendulum. When the tension in the yarn is sufficient to overcome the resistance of the pendulum it moves on to the traverse guide 24 and the true wind-up then commences.

Abstract: 167,394. Raven & Co., Ltd., W., and Knight, G. H. Aug. 14, 1920. Circular machines.-The apparatus for engaging the splicing-thread with the main thread described in Specification 22121/14 is modified by dispensing with the revolving spring device for releasing the trapped splicing-thread and allowing the two threads 3, 13, to travel round together for several revolutions, the splicing-thread, 3 being wrapped round the main thread 13 by the action of a pin 7 on the revolving guide 4. After this the splicing-thread end, if not forcibly pulled out from between the trapper jaws 1, 2, is released 'by withdrawing the trapper when a projection 17 makes contact with a drop-piece 19 on the frame 1<a>. A stop-pin 21 prevents the droppiece. 19 from swinging back and causes it to rock the jaw 2 on its fulcrum 23 and so to open the trapper in a. similar way to the drop-piece 1g described in the above-mentioned Specification. On the forward movement of the trapper, the droppiece 19 swings idly without operating the jaws. While the threads 1, 3 are being twisted together, the jaws 1, 2 are kept closed on the splicing- thread end by the action of a spring plunger 11, the pressure of which can be varied by adjusting- means. A wire arched member 14 or hook 15 mounted on the upper end of the stationary axis part 10 assists in twisting the threads 3, 13 together.

Abstract: 517,608. Coin-freed locks. HEENAN, BEDDOW, and-STURMEY, Ltd., and HOGGINS, S. Aug. 13, 1938, No. 23910. [Class 27] Coin-freed lavatory door locks are provided with means whereby the follower or other part operated by the inside handle is locked against movement when the door is open, thus preventing the indicator being moved to "vacant" position inadvertently while the door is open, and remaining in that position when the door is closed subsequently. A slider C operated from. the outside of the door has a flange c to engage the coin D. The tail-piece e<2> of a rocker E is engaged by the coin so that the rocker is moved to actuate the indicator through the pin-andslot mechanism e'. The follower F, by means of which the main bolt is retracted from the inside of the door, carries a projection f engaging a projection b<1> on the bolt, and a second projection f<1> engaging the arm g of a rocker 'G which is spring-pressed at g' against the rocker E to retain the latter in its raised position. Retraction of the main bolt by the follower thus also operates the rocker G to release the rocker E and allow the indicator to fall. The abovementioned details are all of known construction. According to the invention an additional sliding latch H, Fig. 2 is provided, which has a pin- and-slot engagement with a sliding plate K normally engaging. a lug f<2> on the follower F and preventing the counter-clockwise rotation of the latter necessary to operate the indicator from the inside of the door. When the door is closed, this latch is retracted by the striking-plate on the door frame, and the rearward movement of pin h<1> lifts the sliding member K clear of the lug f<2>.
