Patent GB-2466661-A (GB)
Title: Rake receiver
Inventor: MUIRHEAD DAVID STUART
IPC: H04B1/707
Filed: 2009-01-05
Abstract: A rake receiver for a femtocell base station, the rake receiver used for receiving a multipath signal and comprising a plurality of fingers, and wherein the rake receiver is adapted to assign multiple fingers to the same path in the multipath signal. A coarse timing searcher may be used to identify paths in the received multipath signal. Also described is a configurable user mobile equipment comprising said rake receiver in communication with a femtocell base station. A complex/fine timing search/tracker may no longer be required to be used in the arrangement as fingers are assigned at sub-chip (i.e. less than one chip apart) accuracy. Thus a power-saving arrangement is also possible for a user mobile equipment in communication with a femtocell base station as described.

Title: Improvements in Electrical Oil Switches.
IPC: H01H3/30
Filed: 1918-06-19
Abstract: 129,763. Ferguson, Pailin, & Co., Ferguson, S., and Pailin, G. June 19, 1918. Automatic circuit-breakers.-A loose handle a movable in a vertical plane is connected to the operating-levers of an oil switch by the engagement of the forked end j of a lever i pivoted at h with a pin k on the handle, the forked lever being held in engagement with the pin by a trigger lever m adapted to be tripped either before or after the switch is fully closed. The main switchoperating lever g is connected by links f , f<1>, h<1> to a two-armed lever e pivoted to the framework at d. The trip mechanism comprises a lever r pivoted at sand connected to a rod t adapted to be raised by the armature v of the overload coil u, thereby causing the arm r<1> of the lever r to engage the trigger lever m and release the forked lever i. The rod t is provided with a knob x by means of which the rod may be raised to trip the switch by hand. A no-volt coil y is provided, the armature z of which, on failure of the current, raises a rod 3 carrying a disk 4 adapted to engage the knob x of the rod t. The operation of the switch by the no-volt coil is prevented until the switch is closed bv means of a rod 7 connected to a lever 5. On closing the switch, the lever e engages the end of the lever 5 and raises the rod 7 out of engagement with the disk 4 on the rod 3, thereby bringing the no-volt coil into operation. The armature z of the no-volt coil is held in the raised position by the rod 7 until the switch is closed, thereby enabling a smaller no-volt coil to be used. In the closed position of the switch, a spring-controlled catch 10 on the handle is held in engagement with a plate 11 on the framework by a rod 9 carried by the lever 5, so that the switch can only be opened through the trip mechanism, which can be operated manually by raising the rod 3 or by means of the knob x on the rod t. A shunt trip coil, operating in the same manner as the overload coil u, may be provided when it is desired to prevent the switch from being closed under certain conditions, e.g. until a starter is in the off position. The trip arm r<1> engages the trigger lever m at a point near its pivot when the switch is being closed than when it is actually closed, thus enabling the switch momentarily to take a heavier current during the closing movement without operating the trip mechanism.

Abstract: 716,912. Telephone transmission systems. TELEFONAKTIEBOLAGET L. M. ERICSSON. April 24, 1952 [April 24, 1951], No. 10333/52. Class 40 (4) An amplification device for both voice and signalling voltages comprises a valve 11 having a cathode network 13 having high impedance for voice voltages but low impedance to signalling voltages and whose lower end 12 is connected, to earth via a condenser having low impedance for voice voltages and to a diode 8 connected to a source of biasing potential so that the amplifier has negative feed-back for voice voltages but when the signalling voltage exceeds a predetermined limit the diode conducts to cut out the negative feed-back. As shown voice signals are applied to terminal 2 and taken off the output terminals of the transformer 3. Signalling relay 4 is normally operated by anode current, but negative signalling potential of sufficient magnitude on terminal 2 causes the diode 8 to conduct and remove the negative feed-back thereby permitting a large drop in anode current to release the relay 4. In a modification, Fig. 3, an anode filter is provided to improve the frequency characteristic, voltage and current feed-back circuits being provided in combination to match the output impedance of the tube to the filter. In a modification, (Fig. 2, not shown). The diode is oppositely poled so as to conduct when the signalling voltage exceeds a prescribed upper limit. The arrangements may be combined and two such diodes provided so that the negative feedback is cut out in either case.

Title: Device for sealing a rotatable plug in a nuclear reactor
IPC: G21C13/073
Filed: 1972-03-07
Abstract: 1332616 Reactors COMMISSARIAT A L'ENERGIE ATOMIQUE 7 March 1972 [17 March 1971] 10537/72 Heading G6C In a nuclear reactor a rotatable plug adapted to bear the fuel element manipulating system is mounted either directly in the reactor vessel or in another plug secured to the vessel and comprises a member 1 extending into the orifice 3 to be closed and secured outside the vessel to a ring 2 on a track 4 borne by a stationary element 6 which is either the vessel wall or the stationary plug. The periphery of ring 2 is cut away to form a slightly convex friction track 8. A tubular base 12 coaxial with ring 2 is secured to element 6, and a flat annular seal 10 rests on base 12 and on track 8, the outer portion of seal 10 being retained on the base by a ring 14 and screw 16. The inner portion of seal 10 rests on track 8. Seal 10 comprises a p.t.f.e. layer 18 in contact with the track 8, and a rubber layer 20 of the same size as and disposed above layer 18. Between and above the two layers there are annular spring strips 22, 24. The resulting force on track 8 is sufficient to provide adequate sealing-tightness when the reactor is shut down and the plug rotated. When the reactor is in operation a hollow seal 26 disposed in a groove 27 formed in a ring 28 secured by screws 30 to ring 2 above the track 8 is inflated and exerts sufficient pressure on seal 10 to provide static sealing-tightness between the plug and the reactor vessel. When the reactor is shut down, on the other hand, the seal 26 can readily be deflated, thus reducing the clamping force of seal 10 on track 8 during rotation of the plug. The space 42 between ring 2, seal 10, seal 26 and ring 28 may be filled with a fluid e.g. a silicone, which lubricates the seal 10 and preserves its resilience. In further embodiments, the retractable clamping means comprises either a flat ring (32) parallel with the seal (10) and having control rods (34) extending through the ring (28), external electromagnets (36) for moving the ring (32) to a retracted position when the plug is rotated, and springs (38) for clamping the ring (32) to the seal (10) during normal reactor operation (Fig. 2, not shown), or hydraulic jacks which are borne by the ring (28) (not shown).
