Abstract
For the purposes of measuring the configuration of cylinder bores, at least one measuring probe with a plurality of measuring sensors each having respective radially projecting sensing pins is introduced into the cylinder bore, without the sensing pins touching the cylinder bore, and the sensing pins are then brought into contact with the cylinder wall by relative displacement of the workpiece and the measuring probe with respect to each other. Thereupon the measuring head is fixed with respect to the workpiece and that fixing is maintained by means of a biasing force, whereupon, with the workpiece resiliently seated and with the measuring head decoupled from members which produced the advance movement thereof, the configuration of the cylinder bores is measured by sensing by means of the sensing pins on adjacent parallel circles. The apparatus has at least one measuring probe but preferably a plurality of measuring probes which are arranged in terms of number and position in accordance with the cylinder bores to be measured, the measuring probe or probes being associated with a measuring head which can be decoupled in the measuring position.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
