A speed governor for a rotational drive includes a rotor arranged to be driven by the rotational drive and located within a housing having a cylindrical inner side wall and an end wall. Centrifugal brake shoes are pivotally mounted on the rotor and contact the cylindrical side wall and the end wall during rotation of the rotor in a first direction and to move and remain out of contact with the cylindrical inner side wall and end wall during rotation of the rotor in the opposite direction. The brake shoes may be moved and retained out of contact with the end wall by riding up over a portion of the rotor.

Speed governor for a rotational drive

An anti-tamper device for use with apparatus of the type having a slot for receiving a component needed in use. In one embodiment, a first portion is insertable into the tape receiving slot of a cassette player mounted in a vehicle. When inserted, the portion lies in front of the tape player. The first portion has sprung projections which protrude outwardly therefrom and prevent the device as a whole from being withdrawn from the cassette player when inserted therein. To insert the device the first portion is simply pushed home into the cassette receiving slot. In order to remove the device from the cassette player, the projections must first be compressed by sliding them beneath the first portion. The projections are connected to a slider which is moved to and fro by turning a key in a lock barrel. The device is secured to the steering wheel of a vehicle by a cable having a loop at one end.
