Abstract: 1386803 Pressure die casting machines BNF METALS TECHNOLOGY CENTRE 27 Oct 1972 [28 Oct 1971] 50207/71 Heading B3F [Also in Division B5] In a casting process in which molten metal is forced into a die cavity by gas pressure, means 40 senses when the cast metal reaches a desired temperature and generates a signal, this signal being used to terminate the application of the gas pressure. The signal may also be used to initiate the die opening sequence either immediately or after a set time delay. Alternatively, another signal may be generated when the temperature falls to a second desired value and this further signal used to initiate the die opening sequence. The temperature measurement responsible for the termination of the gas pressure may be made by one or more thermocouples 40 located at the top end of the spine and that responsible for initiating the die opening sequence, by one or more thermocouples 14 located in the die. The circuits for controlling the operation of the machine are the same as that disclosed in Specification 1,288,307, and are such that the initiation of the die opening sequence and the termination of the application of gas pressure only takes place if the temperature sensed by the thermocouple rises above and then falls below the said desired values. Alternatively, a timing device (15) may be used to prevent the temperature sensor from operating prematurely. Reference has been directed by the Comptroller to Specification 1,288,037.

Abstract: 1,242,271. Feel simulator. M. G. OVCHINNIKOV and A. M. TITOV. 24 Oct., 1968, No. 50535/68. Heading B7G. A control system coupling a controller, for example a manual control 10 of an aircraft, and a control rod 9, connected to a booster operating one of the control surfaces of the aircraft, includes an artificial loading device 2 for providing " feel " to the manual control, a first end of which is attached to a lever 7 directly moved by the controller and the second end of which is controlled by a linkage having two conditions between which it is moved by an actuator 3 in the first of which the loading device 2 is moved bodily without changing its length and in the second of which the second end of the device 2 is not movable so that when the controller 10 is moved " feel" is applied to it. The linkage comprises a four-armed lever 7 pivoted on a bracket 1 and having a first arm of length a attached to the rod 9, a second arm of length b attached to the controller 10, a third arm of length c connected to the upper end of the loading device 2 and a fourth arm of length d at the end 12 of which is pivoted a bell crank 6. One end of the bell crank is attached to one end of the actuator 3, the other end of which is attached at 8 to the bracket 1, and the other end of the bell crank is attached at 20 to one end of a rod 4, the other end 21 of which is attached to one end of a lever 5 pivoted on the bracket 1 at 14, the other end of the lever 5 being attached to the lower end of the device 2. If the booster is disengaged so that there is a direct mechanical connection between the controller 10 and the control surface, pivots 8, 14, 21 and 20 define a parallelogram so that any movement that the controller causes in the arm of length c is accompanied by an identical movement in the lever 5 so that the length of the loading device 2 is not changed. If the booster is engaged an electrical signal is applied to the actuator 3 to extend it, rotating the bell crank 6 so that the pivot 20 moves into alignment with the pivot 8. Lever 5 and consequently the lower end of the loading device are now fixed so that a force is felt opposing the motion of the controller 10. The pivot 20 may be stopped in an intermediate position. Alternatively (Fig. 2, not shown) the rod 4 may be replaced by a rod (15) which is of variable length, so that for example in the case of a protracted manoeuvre the amount of " feel " provided by the device 2 may be varied.
