Title: Improvements in or relating to deburring methods and apparatus
IPC: B24B9/00
Filed: 1979-08-08
Abstract: A method and apparatus for deburring the ends of tubes utilises a brush located at the end of an arm projecting from a member mounted for rotation and includes drive means to cause the brush and the arm to simultaneously rotate about axes which intersect at the mid point of the brush. The method and apparatus may include two arms projecting from the same member at an angle to each other, each arm carrying a brush at its face end which is caused to rotate about an axis perpendicular to the axis of the arm, rotation of the member causing the brush to describe a circle having its centre on the axis of rotation of the member. Means are provided for moving the brush into engagement with the end of the tube whereby the brush removes burrs therefrom. <IMAGE>

Title: Timing mechanism
IPC: G01F13/00
Filed: 1979-12-18
Abstract: A timing mechanism having an operating member (2) movable between two predetermined positions in which the operating member is to be located.

Title: Copy camera
IPC: G03B27/32
Filed: 1981-10-16
Abstract: Adjustment of the diaphragm opening required in a copy camera for a given magnification is effected by rotary adjustment of an arcuate member, which bears a diaphragm or magnification scale and is attached to the diaphragm control ring, with respect to an adjacent stationary arcuate member, which bears a magnification or diaphragm scale respectively.
