Abstract
Abstract A relative displacement control apparatus comprising fixed structure (1,11,17) carrying a stopper (18); arm means (13 a ,13 b ) which are pivotally movable with respect to the fixed structure (1,11,17); and movement effecting means (21) for effecting pivotal movement of the arm means (13 a ,13 b ) into engagement with the stopper (18) characterised in that the arm means have at least first and second relatively movable portions (13 a ,13 b ) of which the first portion (13 a ) is connected to the fixed structure (1,11,17) about a pivot axis (12) and of which the second portion (13 b ) is engageable with the stopper (18), the movement effecting means (21) being operable so that, during a first part of its operation, it moves the arm means (13 a ,13 b ) as a whole from a position in which the latter is spaced from the stopper (18) to a position in which it engages the stopper (18) and, during a second part of its operation, it effects pivotal movement of the second portion (13 b ) about the stopper (18) and relative movement of the first and second portions (13 a ,13 b ).

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
199 words
A relative displacement control apparatus comprising fixed structure (1,11,17) carrying a stopper (18); arm means (13 a ,13 b ) which are pivotally movable with respect to the fixed structure (1,11,17); and movement effecting means (21) for effecting pivotal movement of the arm means (13 a ,13 b ) into engagement with the stopper (18) characterised in that the arm means have at least first and second relatively movable portions (13 a ,13 b ) of which the first portion (13 a ) is connected to the fixed structure (1,11,17) about a pivot axis (12) and of which the second portion (13 b ) is engageable with the stopper (18), the movement effecting means (21) being operable so that, during a first part of its operation, it moves the arm means (13 a ,13 b ) as a whole from a position in which the latter is spaced from the stopper (18) to a position in which it engages the stopper (18) and, during a second part of its operation, it effects pivotal movement of the second portion (13 b ) about the stopper (18) and relative movement of the first and second portions (13 a ,13 b ).
Claim 2
Dependent Claim
199 words
A relative displacement control apparatus comprising fixed structure (1,11,17) carrying a stopper (18); arm means (13 a ,13 b ) which are pivotally movable with respect to the fixed structure (1,11,17); and movement effecting means (21) for effecting pivotal movement of the arm means (13 a ,13 b ) into engagement with the stopper (18) characterised in that the arm means have at least first and second relatively movable portions (13 a ,13 b ) of which the first portion (13 a ) is connected to the fixed structure (1,11,17) about a pivot axis (12) and of which the second portion (13 b ) is engageable with the stopper (18), the movement effecting means (21) being operable so that, during a first part of its operation, it moves the arm means (13 a ,13 b ) as a whole from a position in which the latter is spaced from the stopper (18) to a position in which it engages the stopper (18) and, during a second part of its operation, it effects pivotal movement of the second portion (13 b ) about the stopper (18) and relative movement of the first and second portions (13 a ,13 b ).
Claim 3
Dependent Claim

Apparatus as claimed in claim 1 characterised in that the apparatus is provided with sample holding means (16) and sample detecting or examining means (20), one of said means (16,20) being carried by the fixed structure (1,11,17) and the other of said means (16,20) being carried by the said second portion (13 b ) of the arm means (13 a ,13 b ).
Claim 4
Dependent Claim
46 words
Apparatus as claimed in claim 1 or 2 characterised in that the said first and second portions (13 a ,13 b ) of the arm means are constituted by first and second arms (13 a ,13 b ) which are connected together by pivot means (14).
Claim 5
Dependent Claim
