Abstract: The present invention provides an apparatus to support an electrical heating element installed in an oven and extending generally horizontally therethrough from one side of the oven to the opposite side thereof for heating an oven cavity to bake or broil food set inside the oven cavity. The oven cavity has side walls, a top wall and a bottom wall. The apparatus and heating element are located below the bottom wall of the oven cavity. The apparatus includes at least one support bracket extending horizontally in the oven and has a plurality of openings formed therein each of which is generally presented in the upward vertical direction and sized to receive the heating element. The support bracket also has a plurality of standoffs generally presented in the upward vertical direction and having a height sufficient to prevent the bottom wall of the oven cavity from coming in contact with the heating element.

Abstract: A co-ordinate measuring machine has a probe (62) used to touch points on an article (61) under manual control by a user, e.g. from a joystick (69). A computer (71) determines a vector describing the direction of probe movement prior to touching each point. On the basis of the number of points touched by the user and their respective vectors, the computer makes a decision as to the shape of a feature of the article under inspection, e.g. whether it is a flange, slot, boss, bore, internal sphere, external sphere, cylinder or cone. It can then either calculate a relevant geometrical parameter such as a dimension of the feature, or write a part program for future inspection of the feature on further, nominally identical articles (61). This can be done automatically without the need for the user to tell the computer anything about the shape of the feature concerned.

Abstract: An electrical totalizer for forming an output signal with occurrences separated by a minimum time interval and representative of the total number of random occurrences in first and second circuits. First and second input circuits receive occurrences from, respectively, such first and second circuits. First and second bistable state circuits respond to separate strobes for changing states for each occurrence at, respectively, the first and second input circuits. A combining circuit is coupled to the first and second bistable state circuits for forming an output representation for each different occurrence at the input circuits. A separator forms, in an output signal, an output occurrence responsive to an applied strobe for each of the output representations. A strobing circuit is operative during repetitive cycles for applying, during each cycle, a strobe to each of the first and second bistable state circuits and to the separator in a predetermined sequence.
