Patent GB-2110015-A (GB)
Title: Disk drive system
Inventor: LEE SEN LIN
IPC: H02P25/02
Filed: 1982-10-28
Abstract: The system includes a motor control circuit wherein an AC synchronous motor (19) is utilized to drive the disk spindle from a source of DC voltage. The motor control circuit is utilized to convert the DC voltage to an AC square wave which is applied to the motor, a crystal- controlled oscillator (22), being utilized to generate the square wave. Since the motor is synchronous to the oscillator output, feedback from the motor is not required. A delay circuit (U5) is provided between the oscillator output and voltage source (20) to eliminate large current surges which would normally appear on the input line of the voltage source. The relatively small sizes of the synchronous motor and the printed circuit board utilized to mount the drive circuit electronics allows both to be mounted far from the disk and read head, the possibility of magnetic fields affecting either being thereby minimized. <IMAGE>

Title: Gas turbine rotor tip clearance control apparatus
Inventor: KIRKER TIMOTHY JOHN
IPC: F01D11/08
Filed: 1982-11-09
Abstract: A stationary shroud structure 26 surrounding a turbine rotor 22 comprises a ring 30 having a frusto conical inner surface 32 defining a small running clearance 29 with blades 24. The ring 30 is supported from a structure 42, 46 by flexible springs 38, 40 which permit axial movement of the ring from an initial position. In operation a pressure difference is formed axially across the ring 30 and a gas bearing is formed between the ring and the radial extremities of the blades 24. The pressure difference produces a first force on the ring 30 acting in a downstream direction; and the air bearing produces a second force on the ring acting in an upstream direction. Axial movement of the shroud ring from the initial position produces a third spring force on the ring acting towards the equilibrium position. The axial position of the ring 30 is determined by the resultant of the first, second and third forces and controls the running clearance. The gas bearing may be improved by the supply of air from each blade interior 58 to a cavity 52 at the blade tip. Winglets may also be provided at the tip. The ring 30 may include a heat pipe or thermosyphon to reduce thermal gradients. <IMAGE>

IPC: G06M3/12
Filed: 1984-02-02
Abstract: The counting index of a gas meter includes a drum (11) on which is a ring of pins (12). A trip member (17) mounted on a sliding plate (16) rests on an upper one of the pins (12) when the drum is rotating in a correct direction indicated by arrow 3. If an attempt is made to reduce the reading of the meter by winding the counter backwards, the drum (11) is rotated in the opposite direction. The trip member and sliding plate then follow the descending movement of the pin on which the trip member rests, the trip member being shaped to enter between the pins. The trip member and plate drop below the pins on the drum and remain there, indicating that reversal of the count has taken place. A viewing opening (19) is adjacent the plate (16) so that it can be seen that the plate has dropped. <IMAGE>
