Title: Improvements in control systems for prime movers
IPC: H02P23/00
Filed: 1965-08-19
Abstract: 1,088,879. Automatic control of speed and acceleration. GENERAL ELECTRIC CO. Aug.19, 1965 [Oct.28, 1964], No.35565/65. Heading G3R. Sensors 3, 4, generate pulse-signals with a frequency proportional to the speed of a turbine, these signals being applied respectively to speed and acceleration control channels 6, 7. The pulses are passed through amplifiers 8, 9, to converters 10, 11, whereby they are converted to direct voltages proportional to frequency. In channel 6, the direct voltage is filtered and then compared with a reference voltage in summer 14. In channel 7, the signal from converter 11 is differentiated in device 16 and then compared with a reference signal, the resulting error signal being integrated in summer 18. The outputs from summers 14, 18, are applied to gate 20 which passes only the error signal which results in the lesser flow of steam through a valve controlling the turbine. The gated error signal is amplified and actuates electro-hydraulic servomechanism which moves the steam valve by hydraulic rams, the arrangement comprising a valve-position feedback device. The turbine is started under acceleration control, automatic change-over to speed control taking place near the selected speed when gate 20 rejects the output of summer 18 and passes the output of summer 14. Thereafter, variations in turbine speed cause only small error signals which are passed through the gate to control the valve-position. In a modification, both the speed and acceleration control channels are duplicated, whereby, in the event of failure of a component, control is taken over by the duplicate channel.

Nov. 28, 1929, No. 36447. [Class 28 (ii).] A slicing-machine clamp of the kind in which a clamping bar is supported only at one side of the machine by one or more (usually two) uprights, the bar being pivoted to a supporting member on the uprights, is characterized by the provision of a connection of variable length extending between the supporting member and the clamping bar, the said connection comprising elements which are normally locked together by self-acting means adapted to be released by manipulation. As shown, the bar 2 is pivoted at 8 to a member 5 slidable on a post 3 and prevented from rotating by an extension which engages another post in line with the post 3. The means for actuating the release for the member 5 is positioned between the posts. The variable length connection comprises telescopic parts 11, 12 which are locked by a clutch ring 13. A pivoted handle 14 at the free end of the bar has an extension 15 which presses on a rod 16 in engagement with the ring 13, so that, by lifting the handle 14, the clutch is first released and then the freed bar 2 mav be raised.
