Title: An improved cartridge fuse assemble
Inventor: MCGHIE TERENCE VICTOR
IPC: H01H85/25
Filed: 1984-06-18
Abstract: An electric fuse assembly comprises an insulating carrier 1, and an insulating base 2 having fuse contacts each protected by a preformed plastics shroud 3. The shroud 3 is constrained to slide transversely of the insulating base between a first position, in which a slot in the shroud overlies the electric fuse contact, and a second position in which the shroud prevents the insertion of a cartridge fuse link blade into the electric fuse contact. The shroud is urged by an associated resilient means 8 into the second position, and the insulating carrier is provided with means 18 for engaging each shroud and causing it to slide transversely of the insulated base 2 against the action of the association resilient means, so permitting insertion of the fuse link blade contact. <IMAGE>

Title: DC Brushless motor drive control
Inventor: PALOMBO GASTON ALBERT
IPC: H02P6/06
Filed: 1984-09-13
Abstract: Servo system e.g. for the head 12 of a disc drive employs a brushless DC motor 16 and is driven by a single power supply amplifier 18 which can provide a reversible drive current to the phases of the motor. Commutation of the motor is accomplished by electronic commutation circuitry 20. An encoder 24 provides position feedback signals to a microprocessor 28. During a velocity mode the microprocessor 28 generates a velocity profile and compares the actual velocity 26 of the motor with a desired velocity and generates a drive signal to the amplifier 18. The amplifier provides a drive current of direction dependent upon the polarity of the drive signal. During a subsequent position mode of operation, the commutation of the motor is frozen and the error signal is generated as a function of the difference in the actual and desired position of the motor. By freezing the commutation, commutation transients and positioning instability are eliminated. <IMAGE>

Title: Length measurement method and apparatus
Inventor: KAMDAR PRASHANT RASIKLAL
IPC: G01B7/04
Filed: 1986-11-12
Abstract: The simultaneous measurement of the lengths of two elements e.g. the lengths of an optical fibre and its sleeving, is made by feeding the fibre (1) through a first length measurement rig and then through a second rig after the sleeving has been applied. Each rig includes, at a first station, an electrode (7) for applying an electrostatic marker charge to the fibre (or sleeve) which charge is detected at a second station, spaced a known distance from the first station, by electrode (12). Detection of the marker charge triggers pulse launcher (8) to apply another charge to the fibre (1). A count of the marker charges gives an indication of the relevant lengths. The rate of movement of the fibres is measured and a microprocessor keeps a specified relationship between the two rates of movement. <IMAGE>
