Title: Self threading reel
IPC: B65H75/28
Filed: 1974-03-19
Abstract: 1436680 Self-threading reels INTERNATIONAL BUSINESS MACHINES CORP 19 March 1974 [4 May 1973] 12088/74 Heading B8M A self-threading reel comprises a rotatable hub 10 having a plurality of outwardly extending inner vanes 32, a rotatable spool 18a mounted coaxially with the hub 10 and having a plurality of inwardly extending outer vanes 36, and means to rotate the hub, the inner and outer vanes 32, 36 being overlapped and interleaved to permit relative rotatation of the hub and spool and being adapted to co-operate upon rotation of the hub to grip the leading end of a web 57 inserted between the outer vanes 36 to thereby cause rotation of the spool to wind the web on the vanes 36. The vanes are formed with co-operating recesses 32b and projections 36b which permit relative movement of the vanes in the absence of a web 57. The hub is rotated from a prime mover via a pulley 64, belt 66 and slipping clutch. The prime mover also drives the feed rollers 58, 60 for the web 57 which is guided via guide 62 to the reel. When a predetermined length of web is wound on the reel, the end of the guide 62 is pivoted by the wound web to operate a switch 74 to stop the prime mover. The wound web can then be removed axially of the reel. Rotation of the spool also causes rotation of a flange 46 via a friction drive, rotation of the flange 46 being limited by an arm 54 and stop 52. When the wound web is removed, the spool is free to move relative to the hub and a return spring 55 connected to arm 54 causes such rotation of the spool in the reverse direction. This reverse direction is limited by a pawl 40 acting on spaced projections 19a on the spool, the pawl being positioned to stop the spool in readiness to receive the end of the web 57 between the vanes 36. The vanes 32 and 36 are located on chords 32h, 36h as shown.

Patent GB-290245-A (GB)
Title: Improvements in optical systems for the scanning or recombining devices of picture transmission or television systems
IPC: H04N3/08
Filed: 1928-05-02
Abstract: 290,245. Westinghouse Electric & Manufacturing Co., (Assignees of Zworykin, V. K.). May 11, 1927, [Convention date]. Television.-In an exploring device for television transmitters and receivers the exploring pencil passes through two prisms which rotate at different speeds so that it traces out a spiral path. Fig. 1 shows the receiver in which the fluctuating light from a lamp 1 is collimated by a lens 2 and passes through a mask 3 and prisms 4, 5 to a viewing screen 6, the position of which is adjustable. The prisms 4, 5 may have convex surfaces, as shown, or plane surfaces, additional lenses being used in the latter case. The prisms are rotated at high speed, the prism 4 being mounted inside the rotor 10 of an induction motor having a stator 12. The prism 5 is rotated at a slower speed by the magnetic drag exerted on the steel cylinder 14, which carries it, by the steel cylinder 13, forming part of the rotor; its speed is regulated by means of the adjustable brake 18, 19. The scanning pencil of light consequently traces on the screen 6 a spiral path of varying luminosity, the shape of one period of the spiral being shown in Fig. 7. The crowding of the whorls near the periphery of the spiral tends to off-set the loss of luminosity which arises in that region from greater linear speed of exploring, but in order to secure a still more uniform distribution of luminosity a double prism 56, Fig. 6, may be interposed to the path of the pencil. The parts 57, 58, are then superimposed as indicated in Fig. 8, the remainder being masked off. In a modification six prisms 72, Figs. 9, 10 may be employed so to superimpose six adjacent areas of the spiral, the centre of which is masked out by a screen 75. Chromatic dispersion may be corrected by using two kinds of glass at 72, 73. In a further modification, Fig. 13, the scanning pencil passes through a fixed lens system 81, 82, through rotating prisms 4, 5, corrected for dispersion, and in succession through six lens systems 90, 91 (of which four are shown) to prisms 92 whence after two internal reflections it reaches a screen so placed that the areas corresponding to the six optical systems 90, 91, 92 are superimposed. The transmitting apparatus is similarly constructed, mutatis mutandis. Synchonous movements.-The rotors 10 at the transmitter and receiver are driven from the same source and the speeds of the cylinders 14 are adjusted manually by means of brakes 18, 19. In the modification in which use is made only of the parts 57, 58, Fig. 7, of the spiral traced out by the exploring pencil, the time intervals corresponding to the remaining parts of the spiral may be occupied by synchronizing signals.

Title: Improvements in the lubricating systems of internal combustion engines
IPC: F16N13/22
Filed: 1924-05-27
Abstract: 232,801. Raleigh Cycle Co., Ltd., and Viles, F. W. May 27, 1924. Force-feed lubricating.-In a lubricating system for internal-combustion engines, a pipe G connects the outlet of a hand pump J to the inlet A of a mechanical pump B, and the latter is provided with a by-pass D fitted with a non-return valve E. Oil is drawn from a tank H through holes M in an outlet fitting K, a flexible washer N acting as a suction valve. The fitting K is connected to the pipe G and is fitted with a non- return valve L. Both pumps are then adapted to supply oil to the engine from the tank through the same pipe G. A light spring fitted to the piston O of the pump J normally keeps the valve N closed. If the piston O is drawn up to charge the hand pump, the pump B draws from the charge and the gradual fall of the piston indicates that the pump B is working properly.
