Title: Method and apparatus for measuring the dimensions of an object
Inventor: KAESER BEDA
IPC: G01B11/02
Filed: 1993-04-06
Abstract: Laser beams from separate sources are deflected by a rotating mirror and travel over further mirrors and objective lenses into a measuring field for measuring the dimensions of an object 3 in the x and y directions. The result is a simple, compact configuration. The separate optical systems for both measuring directions can be set in an optimum manner independently of one another, permitting great precision.      Thanks to an offset of the optical axis of the incident laser beams relative to the rotation axis of the mirror the measurements in the two directions are made staggered in time so that the measurement signals can be processed in a common measuring channel.

Title: Combination mixer dispenser
Inventor: CAMM STEPHEN JOHN
IPC: B65D81/32
Filed: 1990-12-03
Abstract: A dispenser for dispensing two components is disclosed which comprises a drum (10) in which a tube (20) is supported. A first piston (12) is arranged within the drum (10) and has an opening (22) through which the tube (20) extends. The opening is provided with a plug (80) which has an aperture also through which the tube (20) extends. The plug supports a blade (32) which bears on a second piston (40) arranged within the tube (22). The plug (80) is fixed relative to the piston (12) so that it and the blade (32) move with the piston (12). During movement of the piston (12) the blade (32) slices the tube (20) and bears against the second piston (40) so that the first piston (12) and the second piston (40) move in a fixed manner as a single unit. During movement of the pistons (12 and 40) the two components are dispensed from the drum (10) and the tube (22) in a particular ratio depending upon the volume displaced by movement of the pistons (12 and 401). The dispensed components can therefore be mixed together in the predetermined ratios.

Abstract: An active noise controller includes a prediction filter which comprises a delayer for delaying the noise or error detection signal by a predetermined period of time, a first adaptive filter for processing the output of the delayer to deliver its periodic component, and a subtractor for subtracting the output of the first adaptive filter from the noise detection signal to deliver a random component of the signal. More specifically, the prediction filter is capable of dividing the noise or error detection signal into two, periodic and random, components. In addition, two, second and third, adaptive filters are provided for processing the periodic and random components respectively. Accordingly, the second and third adaptive filters become responsive precisely to their respective periodic and random components regardless of the ratio in level between the two components, whereby any undesired noise consisting of the two discrete components will be suppressed.
