A low profile light comprises mating front and back housings (), between them defining the thickness of the light. An attachment is provided on the back housing, whereby the light is attachable to a base on which the light is to be mounted. A circuit board () mounts circuit elements () and interconnecting conductive tracks to which LED devices () are connected. The board is enclosed and sandwiched between said front and back housings. The front housing is transparent or translucent to transmit light emitted from the LED devices. The circuit elements and LED devices are arranged to be powered by AC mains electricity. The thickness of the light is no greater than 10% more than the sum of the thicknesses of said front and back housings and the maximum 15 dimension of a minimum power-rating two-core mains electricity power cable (). That is, it is less than 10 mm thick.

A method of rocking a wheeled infant carrier () comprises using a rocking device () having a pair of discrete units (). Each unit has a ground-engaging base () and a platform () supported thereon through bearings for movement relative to the base in a first direction. A drive one () of the units has a motor in a housing () arranged to drive the platform () of the drive unit relative to its base back and forth in said first direction. A first wheel () of the carrier () is placed on the drive unit and a second wheel () on the second, slave unit (), with the axes of rotation of the wheels being arranged parallel said first direction. The motor is operated to rock that end of the carrier that is supported by those wheels from side to side.

A power drill has a mode changing mechanism enabling the drill to be operated selectively in a hammer mode and a non-hammer mode. Pivotally mounted upon an internal partition of the drill is a mode changing mechanism comprising a first rigid limb and a second limb consisting of a leaf spring located in side-by-side relationship with the first limb. The mechanism is pivotable into a first position in which the rigid limb is directly behind the output shaft of the drill so preventing rearward movement of the shaft and enabling the drill to operate in a non-hammer mode, and a second position in which the leaf spring is directly behind the output shaft so allowing rearward movement of the shaft and enabling the drill to operate in a hammer mode.

An air cooled bearing assembly for the armature shaft of an electric motor comprises a heat sink with an axial bore and spaced outwardly extending fins along its external surface. The fins are of a greater depth over part of their length and the junction between the parts of different fin depth is round to form a seating for a resilient mounting member. Located in the bore is a bearing sleeve which is an interference fit in the bore.

A stator assembly of an electric motor includes a lamination stack, a field coil, an end cap having a plastics body fixed to the lamination stack, a brush box made of electrically conducting material, mounted on the plastics body, housing brushes resiliently biased towards the axis of the assembly, and a plurality of electrical conductors in the form of strips of predetermined configuration located on the plastics body for making electrical connections between components of the motor. The electrical conductors include a first conductor extending from the brush box; a second conductor extending from a termination of the field coil and a conducting means, which incorporates an inductance, connects the first and second conductors. The inductance in the connection is altered by altering the inductance of the conducting means. The first conductor is wrapped around the brush box to give a good and reliable electrical connection. The end wall of the brush box is connected by a tongue that can be flexed repeatedly to allow brush replacement without the end wall's breaking off. An impedance, typically a capacitor, that is connected across the power supply of the motor, is clamped on the end cap by a plastics clamping arm.

A guide system for guiding the movement of an article such as a router includes a carrier for a guide plate, an arrangement for coupling the carrier to the router and means for enabling the location of the carrier relative to the coupling arrangement to be finely adjusted. This fine adjustment is provided in addition to the coarse adjustment between the router body and the coupling arrangement that it is known to employ.

Adjustable guides

A tool or machine in which the relative position of two components is adjustable has setting means operable in a first mode to set the two components approximately to a desired setting and in a second mode to adjust the approximate setting accurately to a required setting. A tool for routing has a base plate and a depth stop comprising a post extending upwardly from the base plate, a first collar movable along the post, a screw thread on the outer surface of the first collar, and a second collar whose bore is screw-threaded screwed over the first collar. The post includes a surface in the form of a toothed rack, the first collar has a bore one portion of whose surface is formed to engage one or more teeth on the rack to lock the first collar in a selected one of a number of predetermined positions along the post and a spring resiliently biases the first collar into engagement with the toothed rack. A scale operating with a fiducial mark is provided.
