Title: Method and apparatus for drying sheet material
IPC: D21F13/00
Filed: 1956-10-17
Abstract: 822,936. Drying sheet materials. AMERICAN VISCOSE CORPORATION. Oct. 17, 1956 [Nov. 29, 1955], No. 31590/56. Class 34(1) A continuous length of film &c. 4, Fig. 1, is dried by passage over heated rolls 2, housed in a chamber having upper and lower walls conforming to the general contour of the rolls, in counterflow to warm air supplied through nozzles C. Partitions 15, Fig. 2, on the walls divide up the spaces between the walls and the rolls into channels 17, the nozzles being divided by partitions 27 into channels 29 corresponding to the channels 17. Individually-adjustable dampers 31 in the nozzles permit control of the air flow through the channels so that less air flows through the channels at the sides of the film than at the centre. In this way uniform drying is achieved across the width of the film. Vapour-laden air is withdrawn from the chamber through nozzles D each of which is connected through a chamber 35 for the recovery of ethylene glycol &c. evolved from the film to a fan 22 by which the air is circulated through a heater 23 back to the drying chamber. The upper part of the chambers consists of hinged parts 8 adapted to be folded back to the positions shown in Fig. 2 to give access to the rolls for cleaning &c. The humidity of the air may be regulated by steam sprays 39 disposed in the nozzles C and the temperature by heating pipes 37 in the channels 17.

Title: Power operating mechanism for fluid control valves
IPC: F16K31/05
Filed: 1958-10-03
Abstract: 850,338. Friction clutches; change-speed control. PHILADELPHIA GEAR CORPORATION. Oct, 3, 1958 [April 21, 1958], No. 31603/58. Class 80 (2). [Also in Group XXIX] The threaded stem- 12, Fig. 1, of an electric motor actuated gate-valve 11, engages a nut 16 journalled in a casing 15 but restrained against axial motion, the casing 15 supporting a box 17 containing limit switches for stopping the electric motor 35 at the end of the valve opening and closing movements. The valve may be manually operated by a wheel 18 and a declutching handle 19 that prevents rotation of wheel during power actuation. Within the casing 15 is an input gear 21 on a worm shaft 22 that drives a worm gear 23 integral with the nut 16 ; shaft 22 is provided with another worm 25 driving a gear 26 which operates an electric switch 27 having wires 67, 68, 69 connected thereto. Gear 21 is driven from the motor 35 via a two speed gear 31 that comprises a driven shaft 44, Fig. 3, and a countershaft 43, the latter having an input gear 33 fixed thereon and the shaft 44 supporting the output gear 32; relatively small and large gears 46, 47 are fixed to the countershaft 43, which gears mesh with relatively large and small gears 48, 49 journalled on shaft 44. Each gear 48, 49 may be connected to the drive shaft 44 by a normally disengaged multiple disc clutch 50, 51, respectively. Two stationary housings 60 encircle the shaft 44 and each contains a coil 60a, which when energised moves ar armature 61 to clutch the associated gear to, the shaft 44. Terminals 65, Fig. 1, are connected to a source of power, which terminals are joined by wires 66, 67 to the coils 60a and switch 27, respectively, and since the latter is in the drive means of the valve the coil 60a associated with clutch 50 is energised to cause the drive to the valve to be transmitted through low-speed gears 46, 48 during the initial valve opening movement, contined rotation of the switch 27 then energises the other coil 60a so that the drive is taken through the higher-speed gear 47, 49. In this manner an increased force is applied to the valve during the initial opening movement and surging or " liquid hammer " is prevented. The reverse sequence occurs during valve closure. Switch 27 energises only one coil 60a at a time and the point at which one clutch is engaged and the other disengaged is adjustable. In a modification, the low-speed clutch 50 is normally spring engaged so that the valve can still be operated should there be a failure of the coil 60a. Both coils are mounted in a common body and the armatures are disposed adjacent the latter, the coils being simultaneously energised. The mechanism may be applied to any type of fluid-controlling valve.

Title: Calendar mechanism for use in a time-piece
IPC: G04B19/253
Filed: 1972-07-06
Abstract: 1371455 Calendar timepieces K K DAINI SEJKOSHA 6 July 1972 [8 July 1971] 31748/72 Heading G3T The winding stem 9 of a calendar watch is axially movable into three positions; an inner, winding position, Fig.1, an outer, hand-setting position, Fig.5 (not shown) and a middle position in which rotation of the stem in one direction Fig.3 (not shown) adjusts a day wheel 14 alone and rotation of the stem in the other direction Fig.4 (not shown) adjusts a date ring 19 alone. In the winding position a clutch wheel 16, which rotates with the stem 9 but can move axially along it, engages a winding pinion 12. When the stem is moved from the winding position to the middle position it rotates a setting lever 8 in a clockwise direction about a pivot 8a. By means of a nose 8e engaging a projection 10b, this rotates clutch lever 10 counter-clockwise about a pivot 10a and against a bias spring 11. A part 10e of lever 10 urges clutch wheel 16 into engagement with a setting wheel 3, which is pivoted at 3a on an arm le of lever I and which has a swing lever 2 frictionally engaged around its pivot 3a. Lever 2 has a slot 2a through which passes the spindle 4a of an intermediate setting wheel 4 which, together with a further wheel 5, is movable along a slot 1d in lever 1. Rotation of stem 9 in one direction causes wheel 3 to rotate lever 2 clockwise so that wheels 4 and 5 are moved to the bottom of slot 1d and wheel 5 indexes day wheel 14 via an intermediate wheel 13. Upon rotation of the stem 9 in the other direction wheels 4 and 5 are moved to the top of slot 1d so that wheel 5 engages teeth on date ring 19. When the stem 9 is moved from its middle position to the hand-setting position, lever 8 is rotated so that a part 1a of lever 1 disengages from a face 8d of lever 8. Arm le is then rotated counter-clockwise under the action of a second, resilient arm 1c of lever I so that wheel 3 is moved to engage minute wheel 15. The rotation of lever 8 also causes nose 8e to engage another projection 10d on lever 10, thus again engaging wheel 16 with wheel 3. In this position rotation of the stem adjusts the time-indication via wheels 16, 3 and 15. To avoid unintentional rotation of wheels 13 and 15 during movements of the stem between its middle and outer positions, a recess 10g is provided in lever 10 into which nose 8b enters while moving between projections 10b and 10d. This allows spring 11 to rotate lever 10 clockwise so that wheels 16 and 3 are disengaged.

[Classes 38 (iii) and 38 (v).] Automatic control mechanism to ensure that the difference in levels of two bodies of liquid shall not exceed a predetermined amount comprises movable members responsive to rise and fall of the respective liquid levels and a member pivotally mounted relatively to the movable members so that it moves angularly to actuate the control device when there is differential movement of the liquid level but moves translationally without actuating the control device when the liquid levels move together. A rake 10 for cleaning a sewage bar screen 11 is driven by an electric motor 15 which is started automatically by a difference in the liquid levels above and below the screen due to the clogging of the screen. Floats 19, 20, Fig. 2, are arranged in chambers 21, 22, connected respectively by channels 24, 25 to the up-and-down stream sides of the strainer. Float rods 31, 32 are pivoted to either end of a link 33 which carries a mercury switch 43, Fig. 4, which, when the link is tilted sufficiently is closed to connect leads 46, 47 connected in a circuit 16 of a solenoid switch 13 and thus start the motor. A switch 18a associated with the device 10 provides that the device is not stopped until it has reached a defined position. The circuit 16 may also contain a manually operated switch 18.
