Abstract: The invention is a work holding system (79) for adjustably receiving and holding printed circuit boards (325, 804) for automatic machine component insertion. It includes a frame and a plurality of mutually cooperative adjustable board holders. The frame is U-shaped and is made up of framing members (101, 102, 103) each having a linear scale (301, 302, 303) affixed thereto. An adjustably positionable framing member (104) extends across the U and is slidable along the opposed framing members (101, 102) toward and away from the base framing member (103) forming the bottom of the U. Means (171, 173) are provided for indexing, locking the adjustably positionable member (104) to the frame in any desired position. A linear scale (304) is also carried by the adjustably positionable member and all scales have a common datum. The frame carries indexing means (81, 82, 83, 84) to index it to the machine which inserts components. A number of adjustable board holders (321, 335, 601, 602) are slidably carried by the base framing member (103) and the adjustably positionable framing member (104) to receive circuit boards (325) therebetween. The board holders (321, 335, 601, 602) are indexed and locked to the respective framing members in the proper positions for attaching the boards to the frame, and indexing means are carried by at least one of the receiving board holders for indexing the boards to the frame and consequently to the machine for component insertion. Another embodiment of the invention includes a second pair of adjustably positionable framing members (105, 106) slidable along the opposed framing members (101, 102) between the first adjustably positionable framing member (104) and the mouth of the frame. This pair is equipped with similar structure, as previously described, in order that second or further circuit boards (804) may be indexably received and supported between the further pair of adjustably positionable framing members. The plurality of adjustable board holders is universal in ability to receive and index any type of circuit board. Alsα, the provision of the second pair of adjustably positionable framing members (105,106) permits 90° of circuit boards from one side of the frame to the other side of the frame for insertion of components at 90° to those inserted at the first location.

Abstract: A motor operated valve, typically a butterfly valve driven by a synchronous electric motor (16) is provided with a torque sensing arrangement wherein an cyclic electrical signal representative of the rotational speed of the motor is produced by magnets (22) on disc driven by the motor and Hall effect switches (23, 24). The frequency of this signal is compared in a circuit (43) with the frequency of current supplied to the motor to provide an indication of motor torque. Switches (46, 47) define preset torque limits for the valve. If the limits are exceeded a signal is fed to control logic (41) which operates switches (18) to control the supply current to the motor. The speed signal from the Hall effect switches is also fed to a converter (33) to develop a counter representative of movement of the valve. The output of counter (33) is compared with preset valves defined by switch circuits (37, 38) to define limits of travel forthe valve.

Abstract: An oxygen sensing element of the concentration cell type in the form of a laminate of thin layers supported on a substrate (12). The laminate includes an oxygen ion conductive solid electrolyte layer (20) and reference and measurement electrode layers (18; 22, 24) formed respectively on the inner and outer surfaces of the solid electrolyte layer (20). In operation, a small DC current is forced to flow through the solid electrolyte (20) from the reference electrode (18) to the measurement electrode (22) to maintain a reference oxygen partial pressure at the reference electrode (18). The outer surface of the measurement electrode (22, 24) is covered with a gas diffusion layer (26) of a ceramic material. The diffusion layer (26) is also porous, but the total volume of micropores per unit mass of this layer (26) is not greater than 0.2 cm 3 /g. A preferable thickness of this layer (26) is 10 to 300 m. As the effect of the diffusion layer (26), a partial pressure of oxygen at the measurement electrode (22) becomes below that in an ambient gas atmosphere. When used in combustion gas discharged from a combustor, this element is responsive to a change in the air/fuel ratio in the combustor across a definite value which may be very higher than a stoichiometric value.

Abstract: An adjustable slit plate assembly for a monochromator is formed by two identical metal plates (P1, P2) each having a set of slits (EX1 to EX6 and EN1 to EX6 respectively) with all the slits disposed on a common circle. The plates (P1, P2) are located and supported on a disc (SM) on a rotatable shaft (SH) at the axis (A) of the circle. The slits are each of minimum length to pass a radiant beam of given energy through the monochromator and each set of slits occupies an arc of substantially minimum length. The shape of each plate is substantially a sector of a further circle whose radius and arc are the minimum necessary to accommodate the slits and the axis. The complete configuration of the plates is formed by etching in a single operation, and a greater number of slit sets can be formed together from a plate of given area than for the prior art case in which the two sets of slits for a slit assembly are formed in a single plate in the shape of a complete disc. A significant cost reduction in the slit assembly is thus achieved.
