A part assembly (), comprising: an aluminium part (); a magnesium part (), the magnesium part () coated in a first coating (); a bond (), the bond () securing the aluminium part () to the coated magnesium part (); wherein the aluminium part (), the coated magnesium part () and the bond () are subjected to an electrophoresis coating process to coat the aluminium part () in a second coating (). By subjecting the aluminium part (), the coated magnesium part () and the bond () to an electrophoresis coating process to coat the aluminium part () in a second coating () this may provide a simpler manufacturing process.

An optionally oriented copolyester film comprising a copolyester which comprises repeating units derived from an aliphatic diol, an aromatic dicarboxylic acid and a poly(alkylene oxide), wherein the copolyester film further comprises lithium ions, and wherein the film has a thickness of no more than about 25 μm. The copolyester film is suitable for use a separator in a lithium-ion rechargeable battery.

A posturally supportive toilet seat apparatuscomprising a seathaving a base portion. The base portion has leg support featuresand an apertureformed therein for passage of waste therethrough. The apparatusfurther comprises a back supportwhich extends from a rear end of the base portion. The back supportand leg support featuresare shaped, dimensioned, and, in an in use-configuration, adjustable/positionable relative to each other in an oblique relationship. In the in-use configuration, the thighs and torso of a user seated on the seatare encouraged to form an acute interior angle therebetween, with knees locatable above hips, essentially resulting in the user adopting a squat position.

A low pass filter for use in an image band pass filter of a photoelectron spectromicroscope incorporating a virtual potential surface for reflecting electrons below a particular energy and a special charged particle trap or super dump for unwanted electrons. The filter construction with the super dump reduces the proportion of elastically and inelastically scattered high energy electron escaping the filter.

A drivetrain (48) for an electric passenger vehicle (10) includes a battery (40) for energizing a single-phase A.C. traction motor (18) which drives a ground engaging wheel (12) through a multi-speed transaxle (20). The motor is characterized by an external ferrite permanent magnet rotor (26) drivingly engaging an input shaft (32) of the transaxle. The motor is controlled by an inverter circuit (44) and a control circuit (46) which generates switch command signals to reciprocally actuate power transistors (56 and 62) within the inverter circuit as a function of operator demand, rotor position and rotor speed. The control circuit includes a motor positioning circuit (442) which toggles the motor current when the rotor speed falls below a predetermined level to dither the rotor about a park position for a predetermined period. A pre-start rotor positioner (224) is provided to mechanically lock the rotor in its park position to ensure the availability of a high electrical starting torque. Finally, a minimum starting speed circuit (599) provides for motor startup from other than the normal rotor park position.

An electromagnetic machine (particularly an electric motor) based on the design described in British Patent Application No. 48794/74. Iron losses in this type of machine are reduced by laminating the rotor backing plate (2,4). Although a spiral lamination (FIG. 3) is preferred, an axial stack of insulated plates (FIG. 2) may be employed. Interpolar flux leakage is reduced by radially staggering the U-shaped pole pieces around the stator coil (FIG. 4). In addition or alternatively differently shaped pole pieces may be employed, alternately, around the stator assembly (FIG. 5). Eddy current losses are reduced by replacing the backing plates (2,4) and separate magnets (1,1a,3,3a) with plates (12,14) of sintered magnetic material, permanently magnetized to present alternate North and South poles, therearound. Alternatively eddy current losses are reduced by forming the backing plates from sintered ferrite material (16,18) and mounting either an array of discrete magnets (20,20a,22,22a) or a magnetized ring such as (16,18), therearound.

A scanning monochromator or spectrometer having a reflecting grating whose curvature in the meridian plane is equal to the curvature of a circle upon which the source, detecting means and grating lie and whose lines are ruled with a frequency which varies systematically and directly in proportion to the distance of the lines from a point of origin on the track as determined by the geometry of the equipment, and gratings therefor.
