Title: Supply voltage independent quick recovery regulator clamp
Inventor: RASARATNAM DAYANANDA KUMAR
IPC: G05F1/59
Filed: 2009-06-25
Abstract: A voltage regulator output stage includes a clamp circuit that ensures that the output voltage recovers quickly, i.e. that the perturbation of this voltage is limited and it remains within specification, when entering a standby mode. An output device such as PMOS transistor M_OUT has a clamp circuit MCLMP to reduce the voltage swing on its control electrode in supply independent manner when the regulator is not in a standby mode, allowing faster switching on of the output device when the standby mode is entered. The clamping device can be: controlled according to the signal level on the output device control electrode by another device MSENSE; forced off when in standby mode; and prevent the output device from completely turning off when not in the standby state. The auxiliary voltage regulator can be used to supply low power for a standby mode of a mobile device such as a phone or camera and in parallel with a high current regulator for normal operation.

Filed: 1955-04-13
Abstract: 781,802. Glass manufacture. OWENSILLINOIS GLASS CO. April 13, 1955 [June 28, 1954], No. 10611/55. Class 56. [Also in Group XXX] Apparatus for discharging glass mould charges 17 from each of a plurality of discharge positions 19 includes transfer mechanism comprising shoot means 16 for directing the charges to a series of receiving stations 15, and automatic means 43 for periodically shifting the shoot means from one discharge position to another. As shown, molten-glass container 18 has two openings from which two gobs of glass are cut simultaneously by shears 20 operated by piston 21. The gobs fall respectively into two shoots 16 which together are mounted on a carriage 30 rotated by motor 32. Successive gobs fall down each shoot and are fed to each of the ring of stationary moulds 15 through a corresponding ring of stationary channels 45 as the carriage 30 rotates, for subsequent engagement by plungers 23. The ring 15 of moulds may be considered as forming two sets of moulds, and the shoots are given a second movement (i.e. in addition to their rotation) so that, when the left shoot 16 has fed the left set of moulds, its upper end swings over to the right discharge opening of container 18 and, continuing its rotation, feeds to the right set of moulds. Similarly, the right shoot 16 swings over to the left discharge opening as it rotates round to feed to the left set of moulds. This is effected to each shoot by stationary cam track 43 which imparts a horizontal movement (through gears 55, 54 and shaft 53) to the two parallel links 51, 52 on which (by links 46, 61) the shoot is carried, and, in addition, the shoot is given a vertical movement by pistons 63 which operate to lift plate 66, rolls 67 and rods 59. In this way each discharge opening 19 feeds only to its own set of moulds.
