Title: Improved method and means for drying loosely aggregated material
IPC: F26B17/10
Filed: 1936-02-06
Abstract: 452,633. Drying systems and apparatus. PEHRSON, J. M., and PEHRSON, R. V., 18, Regeringsgatan, Stockholm. Feb. 6, 1936, No. 3665. Convention date, July 31, 1935. [Class 34 (ii)] A method of drying loosely - aggregated material sensitive to over-heating is carried out in two stages and consists in introducing the material into a current of hot gas which transports it to a position where the material is separated from the gas, after which it is finally dried by hot gases which are of a lower temperature than the gas used in the first stage and are passed transversely through the material which is spread out to form a layer. In the construction shown, the material to be dried is conveyed to a hopper 2 delivering to a screw conveyer 3 which feeds the material to a container 4. Hot gases from a furnace 5 enter the container and, together with the material, are drawn by means of a fan 8, through pipes 7, 9 to a separator 10. The container 4 is provided with a rotor 19 adapted to throw the material into the path of the gas current. The material is discharged through an opening 11 on to a screw convever 13 which feeds it to a drying apparatus 14. The apparatus comprises a rotary drum formed with apertures in its circumference through which hot gases are forced by a fan 16, the gases passing through a layer of the material. The hot gases used are at a lower temperature than those used in the container 4 and may be cooled combustion gases from the furnace 5. The material in the drum is automatically fed longitudinally towards the exit 17.

Patent GB-1034451-A (GB)
Title: Improvements in or relating to winding mechanism for laying yarns, filaments, cords and like continuous lengths of flexible material in successive courses to form packages
Inventor: MATTINGLY DENIS ALBERT EDWARD
IPC: B65H54/28
Filed: 1962-01-31
Abstract: In order to prevent the thread reversal points at the ends of a drum-wound package coinciding in successive layers the traversing speed of the thread guide is varied cyclically and its path of travel shifted cyclically in the axial direction but without varying its length.  In a machine having drum wound packages fed with thread by means of thread guides mounted on cables 20, Fig. 5, (not shown), reciprocal movement of the thread guides is effected by means of a cam 24 rocking arcuately shaped members 22 to which the cables 20 are secured.  The cam 24 is driven with a cyclically varying motion from a differential epicyclic gear arrangement (Fig. 4 not shown), housed in a gear-box and comprising input and output bevel gears mounted in line and having intermeshing planet bevel gears mounted on a carrier which is adapted to be oscillated cyclically by a crank or cam (Figs. 2 and 3 not shown).  To obtain the axial shifting of the paths of travel of the thread guides the cam 24 operates on a roller 70 attached to one end of an arm 71 which is mounted coaxially with the member 22.  At the other end of the arm 71 an annular plate 80 (Fig. 6 not shown) is mounted for restrained rotation about a spindle 75 carried by the arm 71, the internal surface of the plate 80 being eccentric to the spindle 75 and serving to transmit the oscillatory movement to the member 22 by means of a follower roller 92.  The outer surface of the plate 80 is formed with ratchet teeth and a spring loaded pawl 88 operates therewith to rotate the plate 80 a fraction of a revolution for each complete oscillation of the arm 71. Thus, owing to the eccentricity of the inner surface of the plate 81, which forms, in effect, a cam track for the follower 92 the relative positions, angularly, of the arm 71 and member 22 gradually alter with consequent shifting, axially of the package, of the end points of the path of travel of the thread guides 19.  A spring, not shown, maintains contact between the roller 70 and cam 24.

Title: Improvements in or relating to magnetic amplifier systems
IPC: H03F9/06
Filed: 1958-02-07
Abstract: 863,931. Magnetic amplifiers. WESTING- HOUSE ELECTRIC CORPORATION. Feb. 7, 1958 [Feb. 13, 1957], No. 4062/58. Class 40 (9). In a cascade connection of resetting magnetic amplifiers in which the set output of a preceding stage is used to back off the reset voltage of a subsequent stage, the leading edges of the reset voltages are delayed relative to the leading edges of the set voltages. This arrangement avoids the cumulative attenuation which occurs when all the amplifier cores are at maximum remanence and the early portion of the set voltage is required to take the core from maximum remanence to adjacent saturation, as well as to overcome back conduction in the reset circuit of each core, during which time the set voltage cannot produce a backing-off voltage for the following stage. As shown in the two-stage amplifier in Fig. 3, set windings 23 and 43 are driven in alternate cycles by centre-tapped winding 73 on a transformer 70, secondary winding 72 of which drives the reset windings 22 and 42 in alternate half-cycles. To delay the leading edge of each reset pulse from winding 72 a saturable core 80 is switched one way when stage 1 or, in general, when the odd numbered stages are supplied with reset current from terminal 61, and is switched back the other way when stage 2 or the even numbered stages are supplied from terminal 62. Non-linear resistance circuits 120, 130 and 140 are provided to give low impedance paths for reset current in the absence of a backing-off voltage. Non-linear resistance circuits 150 and 160 provide a low impedance path to earth for the magnetizing currents necessary to switch core 80 which are in consequence shunted away from the reset windings.

Title: Improvements in or relating to coin freed apparatus or the like
IPC: G07F5/02
Filed: 1928-02-09
Abstract: 311,673. Thrissell Engineering Co., Ltd., (formerly Brecknell, Munro, & Rogers, Ltd.), and Bryan, W. E. Feb. 9, 1928. Coin action, mechanical-connection and with delivery proportionate to value of coin.-Relates to a coin-freed apparatus of the kind in which two or more operations of the release mechanism is permitted upon the insertion of a single coin of two or more times the value of the coin which can be normally inserted to effect a single release of the mechanism. According to the invention, the locking mechanism is moved to its release position by the initial opening movement of the delivery mechanism, acting through the inserted coin, and, after the delivery mechanism has been actuated, the coin is led to another position so that it will again permit of the operation of the release mechanism, the coin being finally delivered to the money-receptacle. The Figure shows a delivery drawer 9 and release mechanism, the drawer being locked by a detent 7 connected to a lever 5 pivoted at 6 and controlled by a spring 10. The detent 7, in the absence of a coin, engages a projection 8 on the drawer to prevent its being pulled out in the direction of the arrow. A second lever 11 pivoted at 12 and controlled by a spring 16 has an arm 13 which is moved by a cam 15 on the initial movement of the drawer to rock the lever. The levers 5, 11 have studs 17, 18, 19 and 23, 24, 25 respectively working in slots 20 - - 22 and 26 - - 28 in a coin shoot 1. A coin inserted through an inlet 2 passes to the position 29 between the studs 23, 17. The drawer is then pulled and the coin transmits the movement of the stud 23 to the stud 17, thereby raising the detent 7. The coin passes to the position 31 from which it drops to the position 33. When the drawer is pushed in, the levers are returned by their springs and move the coin to the position 34 from which it drops to the position 35 to form a connection between the studs 25, 19. The drawer can now be pulled out again to deliver a second article, and the coin passes to position 36 from which it drops through a shoot 3 to a moneybox A single operation of the drawer is permitted by inserting a coin of lower denomination through a shoot 4. This coin passes direct to the position 35. The shoot 4 may be omitted so that the apparatus receives only coins permitting two actuations of the delivery mechanism.
