Patent GB-2302312-A (GB)
Title: Direct drive for printing machines
Inventor: JOHN THOMAS
IPC: B41F13/004
Filed: 1996-06-14
Abstract: Printing rollers 34,35 are each associated with an induction motor 45,46 which drives the roller and also causes the gap 44 between adjacent rollers to close on rotation. The rotors 49, 50 of the induction motors are connected to the rotating casings 51, 52 of the printing rollers 34, 35 and the stators 47, 48 of the induction motors are fixed directly or indirectly to the side wall 36, 37 of the press. In the inactivated state the rotors 49, 50 and stators 47, 48 are arranged opposite each other with a gap 53, 54. The radial position of the printing rollers 34, 35 is determined by means of transverse magnetic forces of the induction motors 45, 46 so that the rollers engage when the drive is switched on. At least one part of the directly-driven printing rollers 34, 35 is provided with an asymmetrical biassing 40, 41, which holds the affected printing rollers 34, 35 in the off-position in the absence of electric actuation in a position eccentric to the printing-on position, so that a gap 44 remains between the co-operating printing rollers. The induction motor can alternatively be arranged between the cylinder axle and the side wall.

Patent GB-2315885-A (GB)
Title: Controlling electric motors dependent on load
Inventor: KIRKHAM RAY
IPC: H02P29/00
Filed: 1996-08-01
Abstract: A system of motors 6, such as the compressor motors of refrigeration units, varies the supply voltage to the motors 6 in steps in dependence on the loads on the motors. The loads on the motors 6 can be determined from the current demanded by each motor, sensed by a current sensor 11, or the temperature of the working fluid in a refrigeration unit, sensed by a temperature sensor 10. If the load on all of the motors is light, the supply voltage is reduced. However, if the load on any one motor increases beyond a threshold, the supply voltage is increased.

Title: Charge and discharge control of multiple battery packs in a portable electronic device
Inventor: BARKAT SHAKIL
IPC: H02J7/00
Filed: 1996-10-29
Abstract: A portable electronic device has detachable main and auxiliary battery packs 101, 102, the auxiliary 101 battery preferably having a greater capacity than the main battery 101. A main battery switch 424, which is controlled by a detector 422 sensing the voltage of the auxiliary battery 102, and an auxiliary battery switch 420 (in the form of a diode 500, Fig.5) control energisation of the device which is initially powered by the auxiliary battery 102 until the voltage of the latter falls below a threshold, whereupon the switch 424 closes to power the device from the main battery 101. The auxiliary battery 102 may be detached while it is powering the device, whereupon the main battery switches in substantially without interruption of the operational state of the device. The main battery can similarly be detached while it is powering the device, whereupon the auxiliary battery takes over, the threshold voltage being above the minimum operating voltage of the device. Connection of an external power source 430 causes the device to be powered therefrom while the batteries are also charged from source 430 via a current regulator 470, 472. A controller 306 senses battery presence through a thermistor switch 446 coupled to thermistors 406, 414 in the batteries. If both batteries are present, the main battery is first fully charged, then the auxiliary battery, and then both batteries are maintenance charged. If a non-fully charged main battery is replaced during charging of the auxiliary battery, charging is switched to the main battery. The device is preferably a radiotelephone, but may alternatively be a lap top computer, camcorder, pager, two way radio, or personal digital assistant.

Patent GB-2324608-A (GB)
Title: Method for conducting moving or rolling check shot for correcting borehole azimuth surveys
Inventor: HOLMES ANNE
IPC: E21B47/022
Filed: 1997-01-10
Abstract: A method is disclosed for correcting the distorting effect of cross-axial magnetic interference on the readings of a well survey tool using a reduced number of measurements and measuring locations. A well survey tool connected to a drill string assembly measures the gravitional and distorted terrestrial magnetic fields at two or more axially displaced locations in an axially extending well bore. The measurements are made from two or more different orientations (tool faces) of the tool about the well axis. Initial values for the tool inclination, azimuth and tool face angle are first determined without correction for the cross-axial magnetic interference introduced by the drill string assembly and the survey tool. Measurements made at each location and tool face are referred to the tool's coordinate system and variations introduced by the different tool face angles are used to estimate the cross-axial interference.
