Title: Improvements in speed governing devices for the carriages of typewriting and like machines
IPC: B41J19/02
Filed: 1920-07-02
Abstract: 166,442. James, R. W., (Remington Typewriter Co.). July 2, 1920. Carriage-retarding devices.-In a centrifugal brake of the kind comprising revolving brakemembers co-operating with a stationary surface, the brake-members are loose and are operated by an independent driver which is coupled to the carriage when the latter is released. The invention is shown in Figs. 1 and 5 applied to the direct and reverse column-selecting mechanism described in Specification 83/15, and comprising stops 21, Fig. 1, which are operated by tabulating- keys and co-operate with column stops 19 on the carriage 7; the feed-rack 10 is raised for carriage release by means of a pivoted frame operated by the tabulating-keys. The pivoted frame is now replaced by a barrel 57 which is trunnioned on a bracket 62 and supports the brake. An enlargement 56 on the barrel is formed with a depression 85, Fig. 5, containing four loose brake-members 94 and a four-armed driver 91 which is secured to a crown pinion 89 gearing with a pinion 81 on a shaft 69 provided with a pinion 73. The driverarms 92 are each formed with a radial side band a non-radial side c, and the end of the arm is out of contact with the rim of the depression 85. The brake members are formed with two straight sides for engaging the driver-arms, and one curved side which is normally out of contact with the rim and is preferably of a slightly less radius than the rim. The shaft 69 passes through an ,enlarged bore in the barrel and is supported at the front by a sleeve on the pinion 73. Flats on the shaft engage a slot in the sleeve, and the reduced part of the shaft passes through the pinion and is expanded at the end. The shaft is supported at the rear by the enlargement 56, a collar 79 preventing endways movement. The pinion 89 is mounted on a stud 87 and is formed with a square head for engaging a square hole in the driver. A cover 95 is provided for the depression 85. On operating the tabulator-keys, the barrel is rocked and the pinion 73 engages and raises the feed-rack, the carriage being thereby released from the escapement and coupled to the brake. In direct tabulating, the carriage runs towards the left and the brake-members are driven by the radial sides b of the driver arms and are caused to move outwards into contact with the rim. In reverse tabulating, the carriage is pushed towards the right and the sides c of the driver-arms operate the brake-members. The sides c, being non-radial, engage the brake-members at the ends, thus causing the brake to offer a greater resistance during reverse tabulating than during forward tabulation.

Title: Improvements in or relating to darning devices
IPC: D04B17/00
Filed: 1922-07-06
Abstract: 206,886. Morley, D. W., and Woodroffe, C. H. July 6, 1922. Darning. - A hand appliance for darning by knitting comprises a housing 2, 3, Fig. 1, to which is pivoted an arm held in position by a spring 1. Arms 5, 6 pivoted to and fixed to the housing respectively are pressed together by hand so that an arm 7, pivoted at 8 on the arm 5, and an arm 40, pivoted at 41 to the housing and pivotally connected to lugs 42 on the arm 5, are actuated. The arm 7 engages a slot, 9 in a member 10, Fig. 3, freely mounted in a vertical raceway. Pins 11 on separate needle blocks 12 engage in another slot in the, member 10. When the needles 13 are fully withdrawn, the arm 7 is at the right-hand end of the slot 9. When the arm 7 rises, the member 10 is tilted to. the position ]4 and then raised bodily to the position 15. During this movement the arm 7 displaces string-connected vertical and horizontal slidera 18, 25 against a spring 27, Fig. 5, until the sliders contact to free the slider 18. from the arm, when the spring 27 returns the sliders and swings the arm 7 from right to left, Fig. 5, so that the member 10 is raised to the position 16, the needles being raised consecutively to the highest position. On the downward movement of the arm 7. due to a spring between the arms 5, 6 the needles descend in a similar manner, the arm 7 and the needles being returned to their original position by sliders 45, 46 and a spring 47, Fig, 5. The needles rise through needle-slots 4, Fig. 1, and between prongs on a spring yarn-guide 36. When the needles are fully raised, yarn 31 is laid in the guide by swinging a bobbin-arm 33 on its pivot 34 from one side of the apparatus to the other. During the descent of the needles, the blocks 12 are pressed forward into a recess 133, Fig. 1, so that the needle-beards are closed for passage through the work by a presser 35, and the yarnguide 36 is pressed aside to allow the loops to be drawn therefrom. After the needles have left the work, prongs 37 on a blade-spring 38, which is fixed to a rod 39 pivoted to the lever 40, pass through the needle-holes 4 to feed the work. For removing and replacing the work, the latch 1 is removed and the pivoted arm raised. The Provisional Specification describes a modification in which the needles are mounted in a single block and penetrate the work simultaneously, and refers to means for varying the needle-spacing and the number of needles in action.

Abstract: 1485358 Colour television tubes INTERNATIONAL STANDARD ELECTRIC CORP 6 May 1976 [7 May 1975] 18599/76 Heading H1D In a shadow-mask colour television tube, mislanding of electrons on the phosphor dots resulting from thermal expansion and distortion of the shadow-mask is reduced by applying the anode voltage to the shadow-mask, and connecting the fluorescent screen to the shadowmask through a resistor of a valve chosen to generate a potential difference producing correcting deflection of the beams between the shadow-mask and the screen. Since the potential difference varies with the beam current, the arrangement connects not only for warm-up effects, but also for mislanding due to the prolonged flow of high beam current corresponding to the production of a bright picture. The conductive aluminium coating 3 on the fluorescent screen 2 is connected to the shadow-mask either by a resistive foil, or by a suitable laquer layer envelope coating replacing the usual graphite layer, or the resistive material may be incorporated in a terminal portion of the aluminium layer and make contact by a spring with the shadow-mask.
