Title: Improvements in or relating to Gradient Delineators.
Inventor: NELSON HERBERT OLIVER
IPC: G01C7/04
Filed: 1965-07-28
Abstract: 1,162,512. Recording clinometers. H. O. NELSON. Sept. 19, 1966 [July 28, 1965], No. 32240/65. Heading G1F. A gradient indicating and recording device comprises a wheeled carriage 1 one of the wheels of which is adapted to drive an input shaft 8 to a ball resolver 7 the ball of which is driven by a roller whose axis is maintained horizontal by a pendulum 16 so that the axis of rotation of the ball remains horizontal two output drive rollers being provided for driving respectively a record strip 51 longitudinally in accordance with the actual horizontal movement of the device, and a marker 67 transverse to the strip in accordance with vertical movement of the device. The carriage 1 is mounted on wheels only one of which (3) is shown, the other serving to drive a pulley 13 by way of a toothed belt 14. The pulley 13 drives the shaft 8 by way of gears 9, 10, the shaft 8 being mounted for rotation in a hollow shaft in turn mounted for rotation in the casing of the ball resolver 7. The hollow shaft carries the driving roller for the ball and the axis of this roller is maintained horizontal by the pendulum 16 which is carried by the hollow shaft. The pendulum comprises a weight 17 moving in an oil filled damping chamber 18, one wall 19 of which is transparent and marked so that the inclination of the pendulum can be viewed. Guide wheels 20 on the weight 17 restrain sideways movement thereof. One of the output drive roller 30 is positioned to contact the ball so that it rotates at a speed dependent on the actual horizontal movement of the device over the ground to be surveyed. This drive roller 30 is carried by the frame of the device and thus will move relative to the rotating ball as the device ascends or descends a gradient. In this way the record strip 51, which is perforated at its edges to engage with its drive roller is driven at a speed proportional to the horizontal movement of the device. A spray clutch is preferably fitted in the drive to the strip 51 so that it is only driven whilst the device is being pushed in a forward direction. The other output drive roller (not shown) is arranged to contact the ball of the resolver and to be driven at a speed proportional to the vertical movement of the device. This roller drives a helically grooved spindle 63 to move the marker 67 across the strip 51 in accordance with these vertical movements. Spring-loaded idler rollers, as 26 are mounted opposite each drive roller to locate the ball, and the whole mechanism is preferably encased to enable it to be used under water. In an alternative arrangement the output drive rollers are mounted in a cage whose attitude is controlled by the pendulum and the drive to the ball of the resolver maintains the rotational axis of the ball fixed with respect to the carriage 1.

Title: Improvements in or relating to braun tubes for use in television receivers
IPC: H01J29/84
Filed: 1949-12-16
Abstract: 670,152. Cathode-ray tubes. PHILIPS ELECTRICAL, Ltd. Dec. 16, 1949 [Dec. 21, 1948], No. 32346/49. Class 39 (i). In an ion trap for a cathode-ray tube in which the negative ion beam is deviated while the electron beam continues undeviated, the collecting plate on which the ion beam impinges is not located at or near the point of minimum cross-section of the electron beam, and has an aperture for the passage of the electron beam which is any shape other than a centrally located circular hole, and whose centre of gravity is on the opposite side of the axis to the deviated ion beam. The collecting plate is held transversely in an enclosing cylinder, and in each Figure shown the dotted circle 5 indicates the area of impingement of the deviated ion beam. The present construction gives increased efficiency and picture contrast by allowing part of the less dense marginal portion of the electron beam to pass in addition to the dense core. This is effected by extending the central hole in any direction other than the direction of deviation of the ion beam. Fig. 3 shows an eccentrically located hole 8, and Fig. 6 a symmetrical slot. In Fig. 4 about half the plate is cut away, in Fig. 5 even more, while in Fig. 7 only so much of the plate is left as will intercept the ion beam. In the arrangement of Fig. 4, a central recess 9 or elevation facilitates centring the beam. Specifications 498,491 and 538, 684 are referred to.

Yarn is fed to a multifeed cylinder and dial knitting machine either positively by two coacting feed members or with slip by one of the members only. In Fig. 5 the yarn is positively fed between an endless band 10 driven from the machine drive and a roller 22 which is free to rotate and is driven by the band 10. The roller 22 may be swung out of engagement with the band 10 and in this position the roller 22 is driven by an electric motor mounted inside the roller to feed the yarn with slip. The motor is switched on and off by the pivotting action. In further embodiments (not shown) the band 10 is replaced by a second roller driven from the machine and in these cases the second roller is pivoted out of contact with the roller which is driven by the electric motor causing the electric motor to be switched on and the yarn fed with slip.

Title: Drive device for either intermittent or continuous driving of perforated film
IPC: B65H20/22
Filed: 1975-08-05
Abstract: 1514820 Drive mechanism for cine projectors KINOTON GmbH 5 Aug 1975 [8 Aug 1974] 32605/75 Heading G2E [Also in Division F2]  The film drive in a cinematographic device such as a projector can be changed from continuous to intermittent, or vice versa, by means of a clutch mechanism. As shown, a continuously rotating shaft 1 carries a disc 3 on which is mounted a pin 2. As disc 3 rotates, the pin 2 engages with a Maltese Cross gear 4 mounted on a shaft 5, so producing an intermittent drive, the film feed sprocket 6 being carried at the end of shaft 5. A gear-wheel 7 on shaft 1 meshes with a gear-wheel 8 forming part of a clutch member 9, which in the position shown rotates freely on shaft 5 via an intermediate bushing. A fork 11 embraces both gears 7, 8 and can be displaced to the left from the position shown, so carrying both gears with it. Movement of gear 7 to the left causes the whole shaft 1 to move with it, so that pin 2 moves clear of the Maltese Cross gear, and no longer engages with it. Movement of gear 8 to the left causes the member 9 as a whole to move likewise, so that pins 10 on member 9 engage between the arms of the Maltese Cross gear. Thus the drive now transmitted from shaft 1, via gears 7, 8, member 9 and pins 10 to shaft 5 is a continuous drive. This imposes less wear on the transmission in the case of fast wind or rewind.

Abstract: 1,013,143. Controlling jet propelled aircraft. BRISTOL SIDDELEY ENGINES Ltd. Sept 11, 1962 [Sept. 14, 1961], No. 33011/61: Heading B7G. [Also in Division F2] An aircraft has nozzle systems 7, 8 each adjustable to vary the orientation of its thrust vector FV 1 , RV 1  in a vertical fore-and-aft plane through the aircraft's c.g., the orientation centre cf of vector FV 1  being forward of and lower than said c.g. and the orientation centre cr of vector RV 1  being rearward of and not higher than said c.g., in the first range of movement of the vectors from vertical, the vector FV 1  moves forward until its moment about the c.g. is a maximum whilst vector RV 1  does not move forwards of the vertical, and in a subsequent range both vectors turn forwards together until vector FV 1  is horizontal or nearly so. Nose-up pitching during take-off can be balanced out by nozzles 9, 10 but by keeping vector RV 1  vertical or moving it rearwardly during the first range this pitching can be at least partly balanced. In one system of controlling nozzles 7, 8, Fig. 3, a shaft 21 connected by lever 22 to a pilot control, carries discs 23f, 23r having cam-tracks 24f, 24r engaged by rollers on plunger 26f, 26r which have rotatable worm sleevess 29f 29r engaging wormwheels 31f, 31r of servomotors 32f, 32r controlling nozzles 7, 8. A trim shaft 35 can adjust sleeves 29f, 29r through worm-gearing to adjust the vectors in unison to adjust the aircraft attitude in vertical flight, In the first range R 1  of lever 22, cam 24f causes vector FV 1  to turn forward and cam 24r turns vector RV 1  rearward; in range R 2  both vectors turn forward in unison until vector FV 1  is aligned with flight direction 5; and in range R 3 , slot 24f is concentric with shaft 21 so vector FV 1  is not moved whilst vector RV 1  is rotated to the flight direction. In Fig. 7, the front and rear nozzles 41f, 41r are adjusted by air driven servos 42f, 42r supplied with air from pipe 46 through shut-off valves 47r, 47f and valves 48f, 48r controlled by a scheduling device 49 receiving input 50 from a pilot's control which adjusts the nozzles to the appropriate positions. Devices 52f, 52r compare signals from repeaters 51f; 51r representing nozzle movement with a signal from device 49 and any difference in excess of a permitted tolerance causes closure of the respective valve 47f, 47r until the fault in the nozzle has been rectified. In Fig. 8, not shown, the front nozzle is adjusted through a servo from the scheduling device and movement of this nozzle operates a valve of a second servo which adjusts the rear nozzle; signals from the rear nozzle and scheduling device are compared to ensure correct functioning. In Figs. 9, 10, 11, not shown, the nozzles are adjusted through a system of gears (Division F2).
