Title: One button security lockdown of a process control network
Inventor: SCHLEISS TREVOR DUNCAN
IPC: G05B19/418
Filed: 2009-09-25
Abstract: Proper function and security of a complex network for communicating data within a process control system maybe manually or automatically "locked-down" with a single command for an entire process control network or portions of the network. A user or application monitors network communication over multiple network devices. Once the network is configured and properly communicates data over the process control network the application may lock down the network by deactivating or "locking out" access points (ports/points/addresses) on the network that are open and unused or have invalid connections, for example ports that are unused may be disabled by removing electrical power from the port(s) or by suspending bridging functions. Locking down the network may essentially freeze it in a properly configured and functioning state and restrict future reconfiguration of the network devices or harmful communication over an open or unused access point. When locked, if a currently connected device is unplugged and a different device is plugged into the access point, the network device may refuse the new connection.

IPC: D06F49/00
Filed: 1965-03-12
Abstract: 1,151,891. Spin driers. SIMPLEX ELECTRIC CO. Ltd. 13 June, 1966 [12 March, 1965], No. 10485/65. Heading F4G. In a spin drier the torque of the brake is increased by a servo-mechanism which derives its power from the rotating assembly of the drier, up to a predetermined maximum, whereafter a torque limiting means operates. The brake comprises a rotating surface 10 fixed to or rotating with the drier drum and at least one brake member 12 mounted for pivotal movement about the axis of a pin 17 in a slot 16 under a thrust derived at least partially from the frictional engagement of a shoe 13 on the member 12 contacting the brake surface 10. This pivotal movement is initiated by release of a manually operable latch (not shown) on the drier lid operating through a Bowden cable 25 and a tension spring 23 connected to an extension 22 of the member. The frictional force established between the shoe and surface causes the brake member to be moved angularly which both advances the leading end of the member towards a stop bracket 30 and also allows movement of the trailing edge by means of the pin 17 and slot 16. This angular movement of the member compresses a coiled spring 20 mounted about an abutment member 21 secured to the drier body until the member abuts thereagainst and is thereby pivoted to increase the pivotal movement of the member and the contact pressure between the shoe and braking surface up to a value determined by the position of the stop bracket 30. The positions of the stop bracket and abutment member are adjustable.

Abstract: 376,359. Table ball games. SCHICHTL, C. and SCHICHTL, L., 63, Rosendale Road, Dulwich, London. April 10, 1931, No. 10636. [Class 132 (ii).] Apparatus for a table ball game comprises a lever 11 controlled by the spring 16 and supported by the bracket 15, having integral with it the starting cup 14 for holding the ball 13. The cup is adjustable to vary the direction of propulsion of the ball the velocity imparted to which can be varied according to the extent the lever 11 is pulled back against the action of the spring 16, the ball passing along the runway 12 and up the ramp 17 to be thrown into the air over the gap 18 to fall through one of the apertures 19, 20, 21 into one of the pockets 22, 23, 24. From the pockets 22, 23, 24 the ball passes to one of the shoots 28, 29, 30 pivoted at 31 and connected at their ends by cords 32, 33, 34 to balanced arms 35, 36, 37 loosely rotatable on the spindle 38 carrying the score-indicating disc 39. Normally the arms rest against stops 64, 65, 66 and the arms carry pawls 41, 42, 43 which, on pivotal movement of the shoots 28, 29, 30 due to a ball running down them, rotate the indicating disc 39 through varying angles determined by the brakes 47, 48, 49. The readings on the disc 39 are observed through an aperture 58 and the disc is retained in its rotated position by a pawl 59 during the return to normal position of the arms 35, 36, 37 and associated pawls 41, 42, 43. The scoring disc is returned to zero through the resetting cord 62 actuated by the ring 63. The shoots, at the end of their rotational movement, are positioned opposite holes 50, 51, 52 through which the balls fall into a shoot 54 leading to a return shoot 27, the balls on falling to the return shoot moving a pivoted metallic plate 55 to close the contact 56 of an electric lamp 57 which may be visible through the opening 58. If the strength of the shot or the direction of the travel of the ball be incorrect it will not enter one of the apertures 19, 20, 21 but will pass to the return shoot 27. Coin-freed mechanism of any known type may be used for releasing the balls.
