Title: Sliver roll forming machine for doubling or drawing frames and like machines
Inventor: BEE JOSEPH RYDER
IPC: D01G27/00
Filed: 1951-12-15
Abstract: 729,438. Sliver roll-forming machines ; sliver guides. FAIRBAIRN LAWSON COMBE BARBOUR, Ltd. March 16, 1953 [Dec. 15, 1951], No. 29408/51. Class 120(1). In a sliver roll-forming machine wherein a roll is formed on a core which, during roll formation, moves away from a roller which drives the roll peripherally and wherein the sliver, being narrower than the roll, is applied to the roll in an undulating manner, the sliver passes to the roll via a conductor which is oscillated during roll-formation by coupling means directly connecting the conductor to the core. As shown, Fig. 1, sliver 1 from a doubler or like machine is directed by an oscillating conductor 7 through a sliver guide 9 onto a roller 11 whence it is wound onto a freelyrotatable wooden core 13 by means of driving rollers 11, 12. Core 13 rotates in bearings 19 which move along slides 21 as the size of the roll increases. The sliver is traversed across the width of the roll by the oscillation of conductor 7 ; this oscillation is effected about a pivot 67 by means of a follower 65 engaging the face of a cam 63 driven, through' change gears 57, 59 and chains 45, 33, from the shaft 17 of core 13. The sprockets engaging chains 45, 33 are carried by links 37, 39 which permit movement of core 13 along slides 21. Follower 65 is pressed against cam 63 by means of a spring 69. In an alternative arrangement, the cam follower is carried by a rocking lever connected by a link to the conductor. Conductor 7 may be replaced by a false twist tube similarly oscillated. Sliver guide 9 consists of a bush 87, Fig. 6, mounted on a shaft 83, and two end plates 89, engaging right and left hand threads on shaft 83, the spacing of which can be varied by turning shaft 83.

Title: Regulating mechanism for back-pressure or boiler-pressure regulated turbines
IPC: F01D21/02
Filed: 1947-11-04
Abstract: 651,471. Turbines ; centrifugal governors. SVENSKA TURBINFABRIKS AKTIEBOLAGET LJUNSTROM. Nov. 4, 1947, No. 29412. Convention date, Nov. 4, 1946. [Classes 57 and 110(iii)] [Also in Group XXIX] In a turbo-electric generator plant having several generators connected in parallel and feeding an electric network 6 and wherein each steam inlet valve is regulated by a fluid-pressure servomotor control system responsive to the speed of the turbine and to either the boiler passage or the back-pressure of the turbine each valve is so arranged that in the event of any one of the turbo-generators being inadvertently disconnected from the network, the pressure-responsive part of the servomotor system associated with the turbine becomes locked and rendered ineffective. As shown, an inlet valve 12 is regulated by a servomotor 11 controlled by co-operating slide valves 6, 8. The valve 6 is slidable and rotatable and under the control of a speed governor 4 having spring-loaded weights 5, so that over a predetermined speed range of the turbine the governor is ineffective and permits variation. in the electrical frequency without affecting the pressure regulation of the valve 12, whilst the slide valve 8 is slidable only and connected through linkage 23 to the spring-loaded piston 21 of a second servomotor 20 and to a motor-driven speed-changing mechanism 13. The piston 21 is formed with serrations 29 coacting with corresponding serrations 30 on the end of the rod 26 of a spring- loaded, single-acting piston 25 and is controlled by a leak-off valve 18 disposed in a fluid pressure line 16, 17 and operatively connected to a spring-loaded diaphragm 15 responsive through a pipe 14 to either the boiler pressure or the turbine back-pressure. In normal operation, an increase in turbine speed causes downward movement of the valve 6 and closing of the valve 12, whilst an increase in the boiler or backpressure causes upward movement of the valve 8 and closing of the valve 12. Conversely. a decrease in speed or a decrease in pressure causes opening of the valve 6. In the event of the turbine being disconnected from the network, an electromagnet 33 becomes energized to open a valve 32 and supply pressure fluid to operate the piston 25 so that its rod 26 engages the piston 21 to lock the latter and so render the servomotor 20 inoperative and hence pressure regulation the valve 12 ineffective.
