Patent GB-1084671-A (GB)
Abstract: 1,084,671. Automatic control of steam pressure. TODD COMBUSTION Ltd. Oct.23, 1964 [Oct. 23, 1963], No.41803/63. Heading G3R. An automatic control system comprises means for detecting the value of a first variable and further means for controlling this variable in dependence upon a second and a third variable, the system being particularly concerned with steam raising plant in which the steam pressure is detected and is controlled by variations in the pressures of the fuel oil and air supplied to the burners of the plant. Thus the steam pressure is detected by means of a servo follow-up system which includes a reversible motor controlled by the voltage appearing across a bridge circuit, one arm of which is sensitive to steam pressure and the bridge diagonal includes a polarized relay sensitive to the direction of any unbalance of the bridge. The motor serves to rebalance the bridge and at the same time controls the position of the sliders of potentiometers in two or more further bridge circuits which form part of further servo follow-up systems for controlling the air and fuel supplies to the steam generating plant. One potentiometer in the bridge circuit of the steam pressure detecting follow-up system has its slider normally out of contact with the potentiometer resistance, the slider and resistance being brought into contact intermittently by means of a motor driven cam which cam at the same time causes a rectified alternating voltage to be intermittently applied to the control system. The system is provided with relays having time delays to allow the air supply to increase more quickly or decrease more slowly than the corresponding changes in oil fuel supply thus inhibiting the production of smoke. An alternative power supply for manual operation of the system is provided.

Objects O are mounted on a base 16, e.g. a theatre stage, between a partly reflecting, partly transparent mirror 14 and a convex mirror 13 and below a lamp 19. When the lamp 19 is switched on a view through the mirror 14 shows multiple reflections in the mirror 13. Further mirrors may extend laterally between mirrors 14, 13, and have their reflecting surfaces directed towards the location of the objects O. Mirror 13 may be of part-spherical form, or cylindrical. In a modification (not shown), mirror 14 subdivides a cabinet into two compartments, the front one having a frontal sheet of plain glass. Each compartment has an independently controlled light source: thus two alternative displays are possible. One of the mirrors may be tiltable with respect to the other.

The pivot means 58 comprise a pair of links, Fig. 4 (not shown), pivotally connected to the steering shaft 40 and tiller 56, and spring means which urge the tiller into alignment with the shaft. The control unit 62 is mounted on the steering shaft 40 and includes a linearly movable elongate cam member 85 which is connected to the twist-grip 60 by a cable 61 extending through the tiller 56 and actuates switches for energizing the motor 28 through acceleration control means 120.

Raw meat is tested to determine how tender it will be after cooking by measuring the resistance to insertion of a probe into the meat while supporting the meat against lateral distortion. The test may be carried out while the meat is still on the carcass so that the bone structure of the carcass gives the necessary support, or cuts of meat may be supported in a clamp. The meat is preferably chilled to a temperature of 32‹F. - 40‹F. Transducer construction. As shown in Fig. 3, four resistance strain gauges 14a are arranged on a common diameter of a flexible diaphragm 14b, the centre of which is connected to needles 17 via an arrangement for decoupling bending moments. Stops 11 limit the depth of penetration and indicate that the needles have been evenly pressed into the meat. Circuit details. The strain gauges 139-142, Fig. 11, are connected in respective arms of a bridge circuit 125 so that the two outermost, which experience compression, are in one pair of opposite arms and the two innermost, which experience tension, are in the other pair of opposite arms, temperature compensation being provided by resistors 141b, 141c connected in the same arm as that strain gauge, 141, having the highest temperature co-efficient. The bridge is energized via wire wound calibration resistors 138a, b (14f in Fig. 3) by a stabilized D.C. source and is balanced by adjusting potentiometer 152 to give zero output when there is no load on the needles. The output of the bridge, when of a sense indicating a compressive load on the needles, is amplified at 148 and fed via diodes 160, 162, 163 to a capacitor 165 which stores the maximum value of the unbalance signal reach during insertion. A high input impedance amplifier 170 connects the capacitor 165 to an indicator 183. Push-button 171 resets the capacitor 165. A potentiometer 180 allows the gain of amplifier 148 to be adjusted for calibration purposes. The indicator 183 may also be used to indicate the state of charge of batteries 134, 135 by reversing the position of switch 136.

Opposite each post 8 is a post 7 carrying the means 23 which have rollers 22 and are moved vertically by motors 24. Each conveyor is moved vertically by chains 16, 17 driven by a motor- 20, and is rotated one revolution at a time by a drive within a casing 13b. A comb 27 on each finger may be moved so that its teeth are horizontal or vertical. A rod is loaded into the apparatus by placing it horizontally on a roller train 41. Placing the rod on the train moves a finger 61 to render an actuator 47 operative to drive the rod onto the means 23, this motion being stopped by engagement of the rod with a contact c which also stops the actuator and pivots it to an inoperative position, and starts the motors 24 to move the means 23 downwardly. The conveyors have been raised to the level of the pair of fingers on which the rod has to be stacked so that the descending means 23 operates a contact which stops the motors 24 and rotates each conveyor one revolution to transfer the rods from the means to the pair of fingers. As further rods are loaded the preceding rods are moved along the pair of fingers. When the pair of fingers support their complement of rods the conveyors are moved downwardly to the next pair of fingers and in so doing the teeth of the fingers above the first pair are moved to vertical positions to space the rods supported by the first pair of fingers. The apparatus may be set for unloading.
