Patent GB-2443379-A (GB)
Title: A gate valve assembly
Inventor: DOW LESLIE WILLIAM
IPC: F16K3/02
Filed: 2006-09-28
Abstract: A gate valve assembly has a body with a valve chamber that intersects a fluid conduit therethrough. A valve gate is disposed in the chamber for movement in a direction transverse to said conduit between open and closed positions. The gate is driven by a sliding stem that is actuated hydraulically by directing pressurised hydraulic fluid into a working chamber defined between part of the stem and a bore in the housing. The assembly also has a rotary override actuator that is actuated manually or by a ROV. The rotary actuator has an eccentrically mounted crank pin that is received in a slot of the stem. The pin and slot combination serve to convert rotational movement of the actuator into a translation movement of the gate member. The pin and slot connection permits operation of the valve through only one half turn. The sliding stem has a pressure balance passage defined therethrough to equalise pressure at both eiids of the stem, thereby eliminating stem ejection forces applied by the fluid passing through the fluid conduit.

Title: Ventilation device controlling air flow into and out of a building
Inventor: TURULOV ALEKSANDR
IPC: F24F7/003
Filed: 2008-05-15
Abstract: A ventilation device to control the flow of air into and out of a building comprises an inner panel 2 located on an interior side of the building, an outer panel 5 located on an exterior side of the building, air vents 1,6,7 through the inner 2 and outer 5 panels each being opened and closed by a damper to permit air to pass from the interior to the exterior of the building. A screen (partition) is located between the inner 2 and outer 5 panels thereby defining a plurality of channels for the passage of the air. During cold periods (i.e. winter), the combination of opened air vents 1, 6 and two air channels creates a U-shaped movement of the air flow through the device that may be heated via a heat exchanger 3 that is heated by absorbing radiated heat. During warm periods (i.e. summer), the combination of opened air vents 7, 6 and only one of the air channels creates a Z-shaped movement of the air flow through the device that by-passes the heat exchanger 3. The screen 8 may be moved to affect the amount of ventilation. Heat exchanger 3 may be made of an air permeable porous material for reducing noise and function as a filter to clean the air from mechanical impurities. The device may function independently or together with a window.

Title: Holographic security marker
Inventor: BROWN STEPHEN CHRISTOPHER
IPC: B42D15/10
Filed: 2008-05-28
Abstract: The invention provides a holographic security marker comprising a holographic security symbol containing encoded digital security data recorded on a thin film data carrier that is laminated to a surface protective film. The replay frequency of the recorded volume holographic data is in a band outside of the visible spectrum, preferably into the infra-red or near-infra-red part of the spectrum. The hologram may be recorded in the visible range and then moved into the non-visible range. The data carrier may for example be a polymeric pressure-dependent light-sensitive material that is capable of volume holographic storage, and which has been cross-linked, after recordal of visible holographic data thereon, after exposing the data carrier to an external pressure which moves the replay frequency of the recorded holographic data to a band width outside of the visible spectrum. Alternatively the polymer may be a swellable polymer which is pre-swollen before recordal of the hologram in the visible range and then dried to contract it to move the recorded holographic data into the non-visible range. The recorded holographic image may be a volume hologram or a volume hologram combined with a surface hologram. The digital security data may be a bar code or a matrix code, and the holographic image of the security data recorded in the volume hologram can be replayed only using suitable camera or data capture equipment which is capable of replaying the hologram within that narrow band width, and capable of reading and if necessary decrypting the encoded digital data. The bar code or matrix code is invisible to the human eye.

Title: Finite state automaton which performs a pattern match by examination of a string of header and content matches
Inventor: LAW DAVID JOHN
IPC: H04L29/06
Filed: 2006-10-27
Abstract: The invention relates to a finite state machine for detecting a pattern match in a character stream, such as a packet comprising a header and a payload. The invention relies on previously determined match states, each match state being associated with at least one respective character string. For example, the finite state machine of Fig. 9 can be used to define the header match states 21-28 and the finite state machine of Fig. 13 can be used to define the content match states 41-50. The finite state machine of the present invention (see for example the accompanying figure) comprises a multiplicity of states (circles) and a multiplicity of transitions between states (lines). Each of the transitions requires the occurrence in proper sequence of a respective one of the match states in a string of match states. For example, the transition between states 70 and 66 requires the match state 44 to occur in the sequence of match states 26, 45, 44. According to the invention, from a received character stream a string of match states is produced (e.g. using header and content matching as exemplified in Figs. 9 and 13 respectively). An example of such a string is provided at 202, Fig. 18. The swing of match states are then examined using the finite state machine of the present invention (e.g. Fig. 14) to determine whether those match states conform to a predetermined sequence of match states. The invention reduces the occurrence of false positives and the need for post-processing.

Abstract: 1,001,809. 809. Photo-electric pressure transducers. AMERICAN OPTICAL CO. March 10, 1964 [April 19, 1963], No. 10022/64. Heading G1A. The invention relates to a photo-electric . pressure transducer comprising a catheter measuring head dimensioned so as to be suitable for insertion into the cardiovascular system to enable the blood pressure at required points therein to be investigated. The apparatus is not only capable of following pressure variations at heart-beat frequencies but also at audio frequencies so that the sound of an internal organ functioning can be monitored at close range. The apparatus consists essentially of a measuring head including a diaphragm 48 which has one side open to receive the pressures to be measured and the other side of which receives light from strands in an optical fibre bundle 24 and reflects the light to a greater or lesser extent according to pressure into other fibres in the bundle. The fibre bundle is made flexible for exploratory purposes and close to the external measuring part of the apparatus is split in junction box 14 into a first group 24.2 which receives light from source 18 and a second group 24.3 light from which falls on a photo-cell 20. The measuring part of the apparatus is preferably arranged as shown in Fig. 5. Lamp 18, fed from a regulated power supply is there shown as feeding into the fibre bundle 12.2 through a half-silvered mirror 72 which directs a reference level radiation beam to photo-cell 76. The instantaneous amplitudes of the signals from the cells 20 and 76 are compared in unit 82 and after amplification separated by low and high pass filters into components having frequencies lower than 60 c.p.s. and higher audible frequencies. The lower frequency signal is modulated in accordance with fluid pressure variations at the measuring head position whilst the other carries any sounds picked up. The outputs may be fed to recorders, oscilloscopes or loudspeakers.

Title: Improvements in foundry moulding machines
IPC: B22C21/00
Filed: 1943-06-23
Abstract: 569,142. Moulding - machines. McCARTHY, J. June 23, 1943, No. 10150. [Class 83 (i)] In a moulding-machine, pneumatic jarring and pressing cylinders 5, 6 are supported by liquid o which receives the reaction thereof and is then discharged to draw the pattern from the mould without much vertical movement of the mould. The pattern-plate is fixed to a table 1 and a flask is placed thereon and charged. Air is then supplied, by passages 13, 14, 14a, 14b, 14c to the space 15a below the jar plunger 4 so that this raises the table 1 until the passage 14 is closed and the space 15a opened to exhaust 15, when the table falls and the operation is repeated as long as required. More sand is then added to the flask, a board is placed thereon, a head 2 is swung into position over the flask and air is admitted to the cylinder 6 by a passage (not shown), in communication with a passage 12. This causes the cylinder 5, now acting as a plunger, to lift the table 1 and compress the sand against the head 2. After the return of the cylinder 5 &c. to the position shown, a valve 8 is opened to allow the liquid, e.g. oil, to flow into a space 9 and the cylinder 6, now acting as a plunger, to fall with the table 1 and pattern-plate, the mould being supported, and thus drawn, by adjustable pillars 23. After the mould has been removed, the cylinder 6 &c. are raised to the position shown by admitting compressed air at 10 and closing the valve 8. In modifications, the sand is pressed successively against heads 21, 2<2>, Fig. 8, carried by a rotatable member A or by two arms, like the arm 3<3>, Fig. 1. The table 1 may have a pneumatic vibrator embedded therein for use during drawing.
