Abstract: A combination carpenter square and bevel/sliding bevel having three triangle-shaped adjoining legs, with an articulating joint between the hypotenuse leg and each adjoining leg. The other two non-hypotenuse legs are capable of being latched or detached by a latching joint that, when latched, forms a substantially 90 degree angle between the two non-hypotenuse legs to function as a carpenter's square. One of the articulating joints at the hypotenuse leg is capable of tightening and loosening. The hypotenuse leg also consists of a slot positioned longitudinally of the hypotenuse leg. The tightening and loosening articulated joint joins the hypotenuse leg with an adjacent leg through the slot, which allows the adjacent leg movement about the joint relative to the hypotenuse leg to function as a bevel. The articulated joints and the detaching function of the latching joint allows the combination square and bevel/sliding bevel to be folded into a compact shape.

Abstract: Apparatus which can be used to calibrate, or provide measurement data on, a machine. The apparatus comprises two structures each with three spherical supports spaced in a triangular array thereon. The supports may be balls or sockets. The structures are interconnected by six members and each support has the ends of two members connected to it. The members are passive extensible measuring bars and the structures are respectively connected to fixed and movable parts of a machine so that movement of the machine parts causes relative movement between the structures and varies the lengths of the measuring bars. From measurements of the lengths of the measuring bars the actual movement of the machine part can be determined. Calibration of the spherical supports is carried out using a measuring bar which is pre-calibrated in a Zerodur jig.

Abstract: Precision measuring apparatus like Co-ordinate Measuring Machines (CMMs) are very susceptible to deformations due to temperature variations and gradients. In a known CCM such variations are counteracted by providing parts of the apparatus with an insulating PUR layer. According to the invention the metrology frame 2 of the measuring apparatus is provided with a heat shield 12, 15 which includes an inner layer 12, having a comparatively high heat resistance, and an outer layer (14) which has a comparatively low heat resistance. Temperature gradients causing deformations of the metrology frame 2 are thus effectively reduced, whereas homogeneous temperature variations can be easily compensated for by means of software correction. Moreover, the shield acts as a low-pass filter which reduces the temperature disturbances due to short-term heat inputs.
