Title: Improved mechanism for driving a sound film or other flexible band
IPC: G03B19/18
Filed: 1947-01-16
Abstract: 648,260. Automatic control systems for flexible band drives. BRITISH THOMSONHOUSTON CO., Ltd. Jan. 16, 1947, No. 1534. Convention date, Jan. 16, 1946. [Class 38 (iv)] [Also in Groups XVI, XX and XXXVIII] Mechanism for driving a film or band at uniform speed over a smooth drum driven by a mechanical or induction slip coupling and having a control member actuated by the relative sizes of loops before and after the drum, is characterized by a servomotor actuated by the control member to control the torque of the slip coupling. In the form shown the film 1 is fed by sprockets 2, 3 over a smooth drum 4 to which is attached a drum 7 driven by eddy currents induced by a rotating magnet 6, the current in which is controlled by a rheostat 23. The film passes round pins 11, 12 on a pivoted arm 14 so that any change in the sizes of the film loops 8, 9 pivots the arm about its axis 10, this movement controlling a mechanical servomechanism 16 by which the rheostat 23 is adjusted. This mechanism comprises two discs 17, 18 on a continuously rotating shaft 19. The disc 20, on shaft 21, is moved by a link 15, connected to the arm 14, into contact with one or other of the discs 17, 18 and is caused to rotate in a direction determined by which disc is driving. The rotation adjusts the rheostat through gearing 22. In another embodiment the arm 14 carries a contact which is brought into contact with one or other of two contacts to cause an electrical servo to run to adjust the rheostat. In further embodiments the drum 4 is driven through a friction drive and the pressure between the frictional elements is controlled by a mechanical or electrical servomechanism. 'The film may be held on the drum 4 pneumatically. The Specification as open to inspection under Sect. 91 refers also to the use of photo-electric cells to detect changes in the relative sizes of the film loops 8, 9, their outputs being fed to a differential amplifier which controls a servomotor. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in and relating to washing machines
IPC: D06F23/02
Filed: 1944-01-28
Abstract: 578,637. Washing - machines. BRITISH THOMSON-HOUSTON CO., Ltd. Jan. 28, 1944, No. 1610. Convention date, Feb. 4, 1943. [Class 138 (ii)] A washing-machine comprises a tub 3, Figs. I and 2, having a scoop 22 which faces in one direction of rotation only, and has its outer end adjacent to, and its. inner end radially inward from, the outer wall of the tub, and a drain from. the inner end of the scoop to the outside of the tub whereby during rotation in the said direction at washing speed liquid is picked up from the lowermost part and drained from the .tub and washing is carried out in the reverse direction at washing speed without draining the tub. The tub 3 has an annular compartment 19 of slightly larger external diameter from which it is separated by a partition 7 perforated at 18. Water is supplied through the hollow drive shaft 4 of the tub. An electric driving motor 10 has a switch 13 for controlling the speed of rotation of the tub and a gear box 11 for forward or reverse directions of rotation. Washing is carried out at low speed and in a clockwise direction as viewed.in Fig..2. The tub is emptied by driving at low speed in a counter-clockwise direction, when water draining through the holes 18 into the compartment 19 is pumped by the spiral vane of the scoop 22 to a central orifice 5 and thence to a drain by gravity or pump means. Drying .may be carried out by rotating the tub in either direction at high speed. At this speed centrifugal force exceeds gravity and water draining off through the holes 18 remains in the periphery.of the compartment 19 until the tub slows down. The annular compartment 19 is large enough to accommodate the water extracted in this process. Rinsing is preferably carried out at the low speed of rotation. In a modification of the compartment 19, Fig. 4, scoops 31 replace the spiral vanes and feed a trough 32 which leads to a drain, pipe 33. At high speed in either direction, water held in the periphery by centrifugal force is deflected by lips 34 to drain as soon as sufficient collects to cover the inside edges of the buckets. 'Thus rinsing can be carried out at centrifugal speed.

[Also in Division G3]  An automatic control valve for an agricultural sprinkler system has a main closure member 11 on the end of a stepped piston for co-operation with a seat 5 between an inlet 3 and an outlet 8. An axial bore 14 extends through the piston to communicate fluid pressure to the large diameter end of the piston and also allow fluid to flow to an outlet 24 past a pilot valve 22 which is held closed by a bucket assembly 27, 28. Evaporation of fluid in the bucket 27 allows the assembly to tilt over, partially opening pilot valve 22 and permitting fluid to flow from outlet 24 into bucket 28. The bucket assembly then rapidly tilts to completely open the pilot valve and also the main valve. The pilot valve closes when bucket 27 is sufficiently full, the majority of the fluid in bucket 27 draining out when in the position shown, lip 34 retaining sufficient to hold the pilot valve closed. In another embodiment a passage extends between the larger diameter bore of the valve housing and the outlet and a solenoid, float or manually-operated pilot valve therein acts as a shut-off valve.

Title: Improvements in or relating to machine and method for applying tape to objects
IPC: B65B7/28
Filed: 1948-01-23
Abstract: 644,643. Applying sealing tape to objects. MINNESOTA MINING & MANUFACTURING CO. Jan. 23, 1948, No. 2104. Convention date, Feb. 27, 1947. [Class 73] A can-taping machine is provided with a rotary carrier to which a can may be clamped, adhesive tape being temporarily anchored to a collar at the centre of the carrier so that on rotation of the carrier, the can is taped, cutters operating to sever the tape after completion of the taping operation. Cans are fed into the machine by a conveyer or other means on to a feed-plate 77 above a bed-plate 26. They engage the nose 79a of a gate 79 and rotate it until a further nose 79d, depressed to the level of the feedplate 77, engages the periphery of a substantially circular carrier 47, level with the feed-plate 77. The can is then locked in position between the nose 79a and a guide 78 extending to the central shaft 48 of the carrier 47. Rotation of the gate 79 closes switch 81 to actuate a solenoid which clutches the carrier to a meter and so rotates it, the cam remaining stationary until a cam portion 47a of the carrier periphery allows the gate 79 to turn further and free the can. By this time a vertical clamping plate 54 has been brought down on top of the can by arcuate cams 58, 581 and followers 60, 601 to clamp the can to the carrier. Sealing tape, supported on a freely rotatable wheel 84, passes behind a roller 83 and its end is adhesively attached to a collar on the shaft 48 of the carrier. As the carrier rotates; the can is brought into contact with the tape which is pressed into position by a roller 85 passing through an aperture 47b in the carrier. The roller 85 is mounted on a spring-urged arm 86 which is depressed by a cam on the underside of the carrier to allow the can and carrier to rotate further. As the carrier rotates, the tape is applied round the can, the tape being severed by cutters 67, 70 after the completion of the taping, the can then being ejected by wipers 71, 711 down a shoot 91. The end of the tape applied to the can is tabbed by a small piece of non-adhesive strip to facilitate removal of the sealing tape from the can. The guide 78 is provided with a channel 102 down which the tabbing strip is fed by a roller 104 which is rotatable in a clockwise direction only. A cam on the underside of the carrier presses back a link 106 which is attached to the roller arm 105, a spring 110 then returns the roller 104 to its original position and as it is not free to rotate in this direction, tabbing strip is fed along the channel of guide 78 to engage the adhesive surface of the sealing tape, forming a double web which is severed as described. The tabbing strip is carried on a freely rotatable wheel 111. A safety switch is described which prevents the machine operating until the guard cover has been closed.
