Title: Liquid dispenser and flexible container arrangement for use in a cistern
Inventor: CHAIB-EDDRA DJAMEL
IPC: E03D9/03
Filed: 2009-01-08
Abstract: The invention relates to a liquid dispenser comprising two major parts, a flexible container and a dispenser unit 4. The flexible container comprises a hard top 3 which extends 5 to carry the dispenser unit 4. Liquid travels to the dispenser unit via a tube 6 whose opening is controlled by a valve 9 operated by a float valve 16. The valve 16 also controls the outlet 11 of the dispenser. As water in a flush cistern drops, pressure is exerted on the flexible container as a siphoning action forces liquid out of the container into the dispenser which holds the liquid until the water level in the cistern rises and operates the float, at which point the liquid flows out of the outlet 11 of the dispenser into the cistern water. The dispenser and container are fitted into any flush cistern in an immersed position.

Title: Securely downloading boot code to a locked system
Inventor: SMITH PHILLIP
IPC: G06F9/445
Filed: 2009-02-11
Abstract: In an electronic manufacturing process allowing mutual trust between designers, fabricators and assembly houses for devices (110, fig. 1) under different power states, a boot-ROM code (BR) stored on a chip (150, fig. 1) is executed to access a 128-bit Secure Boot Key (SBK), 32-bit device key (DK) and 64-bit device identifier (DID) which together calculate a Secure Storage Key (SSK) to protect customer data. The SSK is loaded into the Always-On (AO) domain (140, fig. 1) and decrypts a Boot Loader (BL) on a peripheral device (115-130, fig. 1) which is then authenticated. If this BL authentication stage is failed, eg. when the device has become locked after recovering from a power-up, the chip's DID is broadcast to a secure host 422 which maps the DID to a SBK and returns a message (fig. 6) which is validated using the SBK and subsequently executed.

Title: Improvements in and relating to electric converter devices
IPC: F16H7/14
Filed: 1939-03-31
Abstract: 527,147. Converting. BRITISH THOMSONHOUSTON CO., Ltd. March 31, 1939, No. 10182. Convention date, March 31, 1938. [Class 38 (ii)] In a converting arrangement comprising polyphase discharge devices 30, 40 interconnected through an interphase transformer 7, means are provided for periodically varying the transformation ratio of the interphase transformer to increase the frequency of the D.C. nipple. In the form shown in Fig. 1 the interphase transformer is tapped and connected to the D.C. circuit through a discharge device 70. During the period a conducting anode in group 31-33 has a higher voltage than the simultaneously conducting anode in group 41-43 the anode 71 is conductive and vice-versa. By suitable adjustment of the winding ratio the sixth harmonic will be eliminated. If desired the discharge device 70 may be provided with additional anodes which are connected to the ends of the interphase transformer. In a modification shown in Fig. 5, the star points of the transformer windings 3, 4 are connected to tappings on the interphase transformer 7, the ends of which are connected to auxiliary anodes 71, 72 in the main discharge device 10. In this form, the arc transfer from a conductive anode in the group of anodes associated with the winding 3 to the anode 71 when the voltage applied to the anode 71 from the interphase transformer exceeds that applied to the main anode from the winding 3, and will transfer back to another main anode when the voltage of that anode becomes greater. A similar operation occurs between the auxiliary anode 71 and the main anodes supplied from the winding 4. In this way a stepped waveform of the current is obtained in each parallel operating circuit and by suitable adjustment of the interphase transformer ratio, the sixth harmonic can be eliminated from the output. An arrangement having three twophase groups is described, in which the interphase transformer has three windings and three auxiliary anodes are provided. In the form shown in Fig. 7 the tappings of the interphase transformer are connected through the windings of chokes 73, 74 which are periodically rendered ineffective by means of auxiliary windings connected between the cathode of the discharge device 10 and the auxiliary anodes 71, 72, In a further modification the chokes 73, 74 are provided with additional saturating windings connected in series in the D.C. circuit. The Specification states that grid control may be employed. Reference has been directed by the Comptroller to U.S.A. Specifications 2,082,015 and 2,085,515.

Title: Improvements in or relating to the use of cameras on aircraft
IPC: G02B27/64
Filed: 1923-04-17
Abstract: 218,415. Jackson, P. R., (Sperry Gyroscope Co.). April 17, 1923. Aeronautical photography and apparatus. - In apparatus for stabilizing the line of sight of a camera on an aircraft, and of the kind in which an auxiliary device, such as a mirror, forming part of the optical system of the camera, is so controlled by stabilizing means that it is turned through half the angle of tilt of the aircraft in any plane, the mirror is supported independently of the stabilizing means and is connected therewith so as to be turned through the desired angle. The stabilizing means, comprising a gyroscope 1 with a vertical axis of rotation, is pendulously mounted or. pivots 3 in a gimbal ring 4 pivoted in standards 6 secured to the aircraft. A channelled bail 9 pivotally mounted on standards 6<1> passes over the gyro-casing and engages a roller 12 thereon, so that oscillations of the gyroscope about the pivots 3 are transmitted to the bail. Supported on pivots 16, carried by standards 14, is a frame 15, the lower end of which forms bearings for a shaft 17 which carries integrally a fork 18 in which is pivoted the mirror 19. An arm 22 carried by the gimbal ring 4 is connected by a link 24 to an arm 26 secured at its lower end to the shaft 17, the lengths of the arms 22, 26 being such that the shaft is turned through half the angle of tilt of the ring 4. Mounted on a pivot 29 on an arm 27 secured to the frame 15 is a channelled member 28 engaging a roller 31 on an arm 30 carried by the mirror, and connected by links 33, 35 to an arm 36 on the bail 9, the connection being such that the mirror is turned through half the angle of rotation of the bail. Adjustments are provided as follows for compensating for any errors in the position of the axis of the gyroscope. Mounted on the bail 9 is a level 37, and adjacent thereto is a fixed scale 39 with which co-operates a pointer 41 pivoted at 42 and formed below the pivot with a toothed sector 43 engaging in a rack 44 on the frame 15. The frame can be moved along its pivots 16 by means of the screw 48, the resultant movement of the rack 44 causing rotation of the pointer 41, which is continued until the reading of the pointer corresponds to that of the. bubble of the level 37. The displacement of the frame 15 is shared by the fork 18 so that a rotation of the mirror about the pivots 20 results. A similar level 50 is carried by the gimbal ring 4 adjacent a fixed scale 52 and a pointer 53 carrying a pinion 55 engaging a rack 56 on an arm 57 attached to the spindle 17. The frame 15 can be turned around its pivots 16 to adjust the pointer 53 by means of a screw 59, the resultant rotation of the shaft 17 being shared by the mirror. For locking the gyroscope when necessary against oscillation around the axis 3, 5 a centralizing ring 68, Fig. 1, is provided which can be moved into the operative position shown, or into ;he inoperative position, by means of suitable linkage. Stops may be provided to prevent excessive precessional movements of the gyroscope.
