Abstract: 1,037,173. Programmed control of turbines. RICHARDSONS, WESTGARTH & CO. Ltd. Jan. 29, 1963 [Feb. 5, 1962], No. 4340/62. Heading G3N. In a programmed apparatus for running a steam turbine up to speed, the programme is modified on the occurrence of a temporary decrease in the steam supply to avoid a rapid surge in speed on correction of the decrease. As shown, a time base servo 24 varies the output of a time base 16 comprising a variable ratio transformer, through a servo motor 22. The output F4 from the transformer is fed as a speed reference signal to a known closed loop control apparatus 20 controlling the steam supply to a turbine 12. The speed of the turbine is sensed by a device 10, the output of which is compared in a time-speed servo 14 with a speed reference signal F1 from the time base. When the difference between the reference and actual speed signals is outside of a permissible deviation limit the servo 14 control a servo motor 18 to reverse the programme from the time base 16 until the deviation fall within the permissible limits.

Abstract: 841,021. Carpet sweepers. WILLET & ROBINSON Ltd. Oct. 11, 1956 [Feb. 13, 1956], No. 4487/56. Class 138(1). In a carpet sweeper in which swinging of a bail 2 over the casing 1 in one direction effects lowering of the brush 4 and vice-versa, the bail 2 is journalled to opposite sides of the casing 1 and terminates in eccentric pins 11 forming stub axles for the brush 4. The pins 11 are located in bearing recesses in friction wheels 5 forming the ends of the brush 4, aligning with the axis thereof and in driving engagement with the peripheries of the track wheels 6. The casing 1 has corner rubber buffers 7 and strips 8 at the sides with holes 81 for the bail end and has a detachable cover 9 with a projecting portion 10 for spring engagement with the bail 2 when upright. Lateral displacement of the brush in swinging the bail is accommodated by the resilient surfaces of the wheels 5, or the axles of the wheels 6 are mounted for limited movement horizontally towards and away from the brush axis and spring-urged to contact the wheels 5. According to the Provisional Specification the stub shafts may be formed separately, being rotatably movable in the casing through levers pivoted on the shafts to bring them into operative engagement with the recesses. In a modification of the above forms the shafts have the parts of full and reduced diameter formed coaxially and movable axially to bring either of these diameters into the recesses by means which is part of the bail and operating when it is swung, or by manual means on or in the casing. In a further constructional modification, each stub shaft is journalled in a plate no the casing wherein the brush is mounted and has an outward extension carrying a disc or quadrant with inwardly-projecting teeth which is yeildably urged inwardly by a helical spring on the stub shaft, compressible by a wing nut engaging threads on the end of the shaft, for the teeth to engage in recesses on the plate. Rotation of the disc allows the teeth to reengage in different recesses to give variability in the projection of the brush from the casing.
