Title: Rotary air heaters
IPC: F28F27/00
Filed: 1972-05-22
Abstract: 1397951 Temperature alarms BABCOCK & WILCOX Ltd 22 May 1972 [21 May 1971] 24053/72 Heading G4N [Also in Divisions F4 and H1] In an air heater (e.g. a thermal regenerator, see Division F4) sudden local rise in temperature in a rotor is sensed via the air stream by one or more temperature responsive means and an electrical signal is thereby applied to an electrical circuit, Fig. 3, via an amplifier A. A relay R4 is energized on receipt of a first signal from the member 9, relays R5 and R2 are energized on receipt of a second signal from the member 9, and a relay R3 is energized on receipt of a third signal from the member 9 to operate a warning device AV. If no subsequent signals are received after the first or second signals the electrical circuit is de-energized until another "first" signal is received. After the warning device AV has been actuated the alarm signal persists until the circuit has been restored to its original condition by manual actuation of contacts B1, B2, B3 and B4. The preferred heat sensing means, Fig. 2, comprises a series of thermocouples 10 which react almost at once to any temperature change alternating along a member 9 with thermocouples 11 less sensitive to a sudden temperature change.

Patent GB-1064162-A (GB)
Title: Control and switching means for traversing devices of textile winding and ring twisting frames
IPC: B65H54/28
Filed: 1964-06-10
Abstract: 1,064,162. Builder motions. BARMER MASCHINEFABRIK A. G. June 10, 1964 [July 26, 1963], No. 24112/64. Heading DID. [Also in Division G1] In a building motion device for use in the mechanically or hydraulically powered traversing mechanism of a spinning or winding machine of the type having a pair of switches 10, 11 which are moved in increments and determine the reversal points of the traverse member e.g. of a ring rail 6, the drive to the elements (e.g. threaded spindles 14, 15) which adjust the position of switches 10, 11 is in the form of impulses, the impulses being initiated by a photo-electric or electro-magnetic impulse generator. In the form shown the ring rail is moved by a hydraulic piston rod 1 which also carries a member 12 for alternating actuating switches 10, 11 to reverse the traverse. The drive to the spindles 14, 15, the nature of which determines the shape of the package produced, comes from a motor 18, the drive to the spindle 14 passing via an electro-magnetic clutch 19, 20, a gear box 22 and a shaft 23 and drive to spindle 15 passes via clutch 19, 20, gear box 22, a shaft 24, a gear box 25 capable of reversing drive, gears 26, 27 and a shaft 28. Gears 26, 27 may be replaced by an infinitely variable gear. To produce the desired shape of package, clutch 19, 20 is intermittently engaged in accordance with impulses produced by a photoelectric generator. The generator comprises a pawled disc 44 (see Fig. 3 not shown) which is rotated (via gear 47, 48) to intermittently interrupt a light beam passing from a source 42 to a cell 43. The rate at which switches 14, 15 move (assuming the speed of motor 18 to be constant) is thus dependent upon the total width of the disc pawls 15. To alter the rate at which switches 10, 11 move during a build, a disc having pawls which increase in width towards the centre of the disc is used and the light beam is moved, during the build, towards or away from centre of the disc. A compound disc having two angularly adjustable disc elements may be used. Variable speed gear 25 may be used to alter the relative speeds of rotation of spindles 14, 15 or to drive spindle 15 in the opposite direction to spindle 14. A further control on the motion of switches 10, 11 may be provided by axially reciprocating spindles 14, 15 by means of shaft 23, the reciprocation of this shaft being derived from an eccentric drive powered by the rotation of shaft 23 or it may be independently powered. Limit switches 16, 17, 16', 17' operable by the reversing switches 10, 11 determine the beginning and the end of the build. At the end of the build a clutch 19, 21 is engaged and motor 18 reversed to wind the components back to their initial positions.

[Also in Division F2] A rotary switch mounted at the end of a gearshift lever 16 (see Division F2) comprises a hand lever 18, Figs. 2, 3, and a slotted hub 25 of insulating material turned about the axis of the gearshift lever so that a spring-biased pawl 31, connected to air energized insulated wire 28, can enter a slot 35 in the hub and contact a conducting knob support 24 screwed on to the end of the gearshift lever, itself connected to earth. The pawl 31 co-operates with the slot 35 and with an abutment on the hub 25 to limit the angle through which the hand lever 18 may be turned. In a modified form, the hand lever 18 and rotary switch mechanism are mounted by a universally tiltable ball-and-socket connection 56, 59, Fig. 10, at the end of the gearshift lever 16, a spring 60 biasing the ball &c. to the position shown. When the hand lever 18 &c. is tilted against the bias of the spring 60 relatively to the gearshift lever 16, the lower end 63 of the ball member 63 engages a contact ring 62 energized through an insulated wire 64 and mounted within the gearshift lever by means of an insulating ring 61. As a modification, the ball-andsocket connection 56, 59 can be replaced by a transverse pivot passing through the centre of the ball at right angles to the lever 18. In another modification, Fig. 9 (not shown), the hand lever 18 is fast with a shaft extending down the centre of the gearshift lever and acting at its lower end through a cam upon electrical contacts.
