Title: Improvements in and relating to control systems for power-driven objects
IPC: G05D3/12
Filed: 1941-11-27
Abstract: 583,838. Follow-up control systems. TUSTIN, A., and METROPOLITANVICKERS ELECTRICAL CO., Ltd. Nov. 27, 1941, No. 15314. [Class 40 (i)] A positional control system comprises differential gearing having two elements 17, 18 thereof connected respectively to a controlling member (operating on shaft 7) and the movable object (operating on shaft 6) and a third element 23, differentially moved thereby, which operates on an electric controller 32, 33 to produce an output, dependent in opposite senses on the differential displacement and velocity of the movable device.and controlling member as hereinafter described, for controlling the motive equipment (not shown). The motive equipment may comprise an electric motor controlled. directly by said output or indirectly by means of a metadyne or Ward- Leonard system, or it may operate a moving coil relay to control a variable velocity ratio transmission system, e.g. hydraulic, which controls the motive equipment. The electric controller (variable resistance) may be constructed as described in Specification 577,312, [Group XXXVII], one of the relatively movable parts 32 being driven by shaft 27 coupled to differential element 23, whereas the other is connected to shaft 34 loaded with a spring 42 which determines the displacement component and a damping device 39 which determines the relative velocity component. The operation of the system is similar to that described in Specification 583,835 and any of the damping devices described in that Specification may be used, the device shown being magnetic. The velocity component opposes the relative displacement component when the displacement component is decreasing. The differential element 23 may be coupled to the controller by the spring device 25 described in Specification 577,489, [Group XXIV], providing a solid drive for small torques but enabling the differential element to move relatively to the controller for larger torques. A similar coupling may be interposed between the shaft 34 and the spring 42 so that the displacement component in the output of the controller is non-linear with respect to actual displacement affecting the relationship between the relative velocity component and the relative velocity.

Title: Printing apparatus
IPC: B41K3/02
Filed: 1975-04-15
Abstract: 1469053 Selective printing J A RYLANDER and H R BLOMQVIST 15 April 1975 [16 April 1974] 15479/75 Heading B6F [Also in Division A6] Apparatus for printing combinations of symbols on to a coupon includes a type carrying device and a device on the opposite side of the coupon to the type carrying device. In operation one of the devices is set to a random unpredetermined position before the devices contact each other to print on the coupon. Characters are formed on stationary bar 60 in groups each comprising the characters "1", "2", "X". With each group are associated three discs 48 and hammers 46 (see Fig. 5). Shaft 52 prevents relative rotation of the discs within a group. On each disc the arc width of a recess 48a is one third of their centre-to-centre spacing. When viewed axially no recesses 48a of a disc group overlap. In operation (see Fig. 2), handle 16 is moved clockwise about shaft 18. This movement rotates shaft 50 through gears (132, 134, 136, 138), Fig. 4 (not shown). Each disc group is frictionally engaged by a spring 58 in a bore 56 in shaft 50. The disc groups 48 each have varying degrees of relative movement with the shaft 50 as a result. The gears can also free wheel after being set in motion by handle 16. The grip of springs 58 and the free wheeling of gears provides the random movement of the discs 48. As the handle 16 is moved further pin 32 abuts yoke 64 so that its edge 64 frees hammers 46 to pivot under action of springs 49. The width of the recesses 48a and the relative positions of the discs in a group ensures only one hammer 46 per group can have its tip 46a engage a recess 48a so as to permit that hammer to impress coupon T and ink ribbon R against bar 60. Ink ribbon spool 120 and coupon feed roll 116 are driven by respective pawls and ratchets driven by handle 16 (Fig. 4). A handle (144), Fig. 6 (not shown), can be moved to set the discs 48 so that on any selected horizontal line of the coupon a selected one of the characters of a group can be printed. Alternatively the characters may be carried on the print hammers and further the hammers may be held stationary and the selected hammers impressed by the bar which is moved.
