Title: Detonator
Inventor: CLUTTERBUCK RICHARD CEDRIC D AGNALL
IPC: F42B3/113
Filed: 2012-11-30
Abstract: A detonator comprises two secondary explosives 20, 26, one of the explosives 20 being contained by a rupture plate 14. Each secondary explosive 20, 26 can be initiated by respective trigger 30, 34. Initiation of one of the secondary explosives 20 causes rupture of the rupture plate 14, and a flyer thereof then causes a detonic reaction in the other explosive 26. The other secondary explosive 26, when initiated by its trigger 34, will deflagrate, without causing detonic explosion. The detonator may be a laser initiated detonator and the triggers 30, 34 may include optical fibres.

Title: Tape dispenser with suction gripper
Inventor: HUANG HARRISON
IPC: B65H35/00
Filed: 2012-12-07
Abstract: A tape dispenser has a carrier portion 50 displaceable between an open position (fig.4) and a closed position (fig.8). When transferring to the later stages of the closed position (fig.8), formations, such as a bevel 523, and groove 524, engage and pull upwards upon a transverserod 344. In this manner a suction member 32 is pulled upwards against a spring 40 bias, to clamp the tape dispenser to a surface upon which it is resting. When the dispenser is engaged to a surface it might now be possible to pull tape from the device single handed, as the dispenser will not slide across the surface to which it has been attached.

Title: Method of controlling of a brushless permanent-magnet motor
Inventor: CELIK TUNCAY
IPC: H02P29/00
Filed: 2013-06-13
Abstract: A method of controlling a brushless permanent-magnet motor comprises dividing each half of an electrical cycle of the motor into a conduction period followed by a primary freewheel period. The conduction period is then divided into a first excitation period, a secondary freewheel period, and a second excitation period. The method then comprises exciting a winding of the motor during each excitation period and freewheeling the winding during each freewheel period. The secondary freewheel period has a position and length within the conduction period that acts to reduce the harmonic content of current in the winding relative to back EMF in the winding. As a result, the efficiency of the motor is improved. The secondary freewheel period may occur at a time when back EMF in the winding is rising, and the primary freewheel period when back EMF is principally falling. The method may be used within a specified speed range only.
