Title: A seal arrangement
Inventor: RUSHTON GUY JAMES
IPC: F01D11/04
Filed: 2003-12-20
Abstract: The present invention relates to a seal arrangement, preferably a labyrinth type seal, utilised between a rotating component 41 and a stationary component such as a housing 42. The seal is provided with an edged fin 43 to reduce the leakage gap which extends between the rotating component and the housing. A slot 46, e.g. a nozzle, is further provided directed across the leakage gap in order to present , in use, a fluid flow 40 to further constrict the leakage gap as an effective standing fluid sheet there-across. The slot may have a waisted shape with a convergent-divergent profile through its length. The slot nozzle may be provided in the edged fin or in an opposed surface to the fin. The fluid flow may be inclined towards a higher 48 or lower 49 pressure side, or perpendicular to the opposed side. Preferably several seal arrangements may be combined, in a straight through configuration, or stepped configuration, to form a labyrinth seal assembly. Barrier fins may further be provided on the opposite surface to the edged fin to limit flow through the assembly. The assembly is particularly suitable for use in a turbine engine to provide a seal between the rotor and stator.

Title: Locked breech mechanism
Inventor: TRENDALL SIMON
IPC: F41A3/36
Filed: 2008-04-01
Abstract: A locked breech mechanism for firearms comprises a bolt (3), bolt carrier (4), barrel extension housing a moveable locking means (6), mainspring (8) and operating member (9). The length of operating stroke is minimised because unlocking is achieved by travel of the operating member (9) in one direction, moving locking means (6) causing a load to be applied, via the bolt carrier (4) on the mainspring (8). On a return stroke the operating member (9) is caused to engage the bolt carrier (4), because of a mechanical abutment travel of the bolt carrier (4) causes the bolt (3) to travel, the return stroke further compresses the mainspring (8). At the limit of travel a link (7) engages the bolt carrier (4) with bolt (3) and disengagement of bolt carrier (4) from operating member (9) occurs. The mainspring (8) returns the bolt (3) to battery at which point the bolt carrier (4) is disengaged from the bolt (3) to continue travelling under the influence of the mainspring (8), locking the moveable locking means (6).

Title: Locating hydrocarbons passively by observing a porous oil and gas saturated system giving off its characteristic resonance response to ambient background nois
Inventor: ZUERCHER HANNES
IPC: G01V1/30
Filed: 2009-09-14
Abstract: This patent relates to a method to extract and analyze seismic signals due to resonance phenomena in an enclosed oil, gas, or water reservoir, which are passively excited by seismic background noise, locating thereby the presence of the reservoir by doing qualitative and quantitative estimates via forward modeling. Measurements are first used in a qualitative analysis in eight steps. The influence of gas bubbles is important. A quantitative method in form of a numerical simulation using one of several specific physical concepts is used for further analysis. By using successive forward modeling, together with investigation and feedback and in conjunction with the Monte Carlo method, more details are gained. It is also possible to determine the fluid type. The uniqueness of the methods is first that it is purely passive; second it is directly sensitive to the oil or gas, because the resonance effect is only present for a fluid.

Title: Improvements in or relating to controlling motor cars and the like entirely by hand
Filed: 1934-04-04
Abstract: 436,444. Controlling motor vehicles. KENYON, C. H., 43, Ashcombe Road, Westonsuper-Mare. April 4, 1934, No. 10142. [Class 79 (v)] Relates to vehicles in which the usual controls can all be operated by hand as described in Specification 321,345, [Class 79 (v)], the clutch and brake being operated by a single hand lever. According to the present invention the clutch is released by means of a rocking cam f mounted separately from the hand lever c, means are provided for moving the cam into and out of contact with the clutch release mechanism, and the hand lever is connected by a lost-motion device l to the brake pedal. The lever c is mounted on a shaft a near the gear-box u and has pivoted thereto at 4 a link g having a slot 5 adapted to engage a pin h on the cam f mounted on a shaft e, so that movement of the lever normally rocks the cam. In the position shown, in which the clutch is disengaged and the brake is " off," a groove 8 in the top of the cam is engaged by a roller r mounted on a pin sliding in a slot s in an arm p fixed to the clutch pedal n. To apply the brake the hand lever is rocked rearwardly, the lost motion at l is taken up and the brake shaft 2 is rocked to apply the brakes. At the same time the roller r rides on the top of cam f and the clutch is still held disengaged. When the hand lever is returned to the position shown, the brakes are released. To allow the clutch to engage, the hand lever is moved forwardly from the position shown until the cam f rocks sufficiently to allow the roller r to drop and the clutch pedal to turn. If the brakes are to be applied without disengaging the clutch the link g is rocked about its pivot 4 by means of a rod z and trigger y on the hand lever, so that the link is disengaged from the pin h and movement of the hand lever applies the brakes without affecting the clutch pedal. A horn switch L is mounted on the hand lever. The throttle may be controlled by hand as described in Specification 330,184, [Class 79 (v)].

Title: Rotary shaft actuated apparatus
IPC: G04F3/06
Filed: 1959-03-24
Abstract: 920,703. Electric time switches. AUTOMATIC TIMING & CONTROLS Inc. March 24, 1959, No. 10181/59. Class 38 (5). [Also in Group XXIV] An electric timer has a motor driven continuously rotating friction clutch disc driving a radial finger between two stops, the one on to which the finger is driven having switch contacts that open circuit a solenoid to disengage the clutch, thus allowing the finger to be returned by a spiral spring to engage the other stop. The timer is then ready to complete another cycle on energization of the solenoid. An electric motor (not shown) drives a shaft 21 geared to clutch disc 25 carrying a resilient ring 27. A projecting portion 30 of the radial finger 19 engages this ring when the solenoid 80 is energized to compress a spring 36 by a clevis 41 and link 90 and thus to move the finger to the right. When the switch is opened by the finger impinging on the forward stop the solenoid is deenergized as described above and the finger is driven back by a spring 32 to a back stop 71, set for the appropriate time interval by a knob 53. The timer is secured to a panel 115 by compression screws 113 acting on a flange 111  of the timer case. The latter is dustproof due to gaskets 181, 110, 112 and has a cover 44 with a transparent graduated portion through which the settable stop 71 can be seen and the operating interval thus determined.

Abstract: 639,245. Radio transmitting systems ; valve generating circuits ; pulse modulation. CHAMAGNE, E. L. J., and CHARBONNIER, A. April 13, 1948, Nos. 10193 and 10194. Convention dates, May 7, 1947 and May 14, 1947. [Classes 40 (v) and 40 (vi)] A train of pulses is shaped by a multivibrator, differentiated, and fed to a resonant circuit for the purpose of demodulation if the pulses are position-modulated, and as a synchronizing device for radio transmitters if the pulses are regularly spaced. Pulses, which may be received by radio, are detected at 10, amplified and inverted at 11, 12 and fed to a multivibrator 13 which gives an output of rectangular waveform. This is differentiated at the network 14 to give alternate positive and negative pulses 3, 4 which are amplified and applied to a valve 15 having an anode circuit 16, 17<1> tuned to the mean initial pulse frequency or an harmonic thereof. Both positive and negative pulses 3, 4 contribute to the setting up of oscillations in the tuned circuit, and if the initial pulses are position-modulated, these oscillations are frequency-modulated. Their frequency may be altered by mixing at 19 with a local oscillation, and the mixer output applied to a discriminator-detector 21 and signal amplifier 22. The double pulses 3, 4 may be broadened by an integrating network 17, 171 as they are applied to the tuned circuit. The rectangular pulses from the multivibrator 13 may be all of the same width, or the pulse width may vary in such a way that pulses and adjacent gaps have approximately the same width, so that negative pulses 4 are midway between positive pulses 3. When the system is employed for synchronizing radio transmitters the input pulses at 10 are equally spaced, and the oscillation set up in the tuned circuit 16, 17<1> is of steady frequency. After amplification and frequency multiplication it is employed as the carrier wave of a radio transmission.
