Patent FI-991597-A (FI)
Inventor: SOININEN JONNE
IPC: H04L29/06
Filed: 1999-07-12
Abstract: In an access network which supports a mobile IP protocol, a packet data protocol (PDP) context is opened at support node (SGSN) and a gateway node (GGSN) in order to establish a connection between a mobile node (MS/MN) and a mobile IP foreign agent (FA) located at the gateway node. A mobile IP registration over the connection is initiated. The gateway node (GGSN) monitors (15) whether the registration is successful or fails. The PDP context is deleted (16 to 18), if the registration irrecoverably fails. If the registration was unsuccessful but a retry could be successful (the first failure was due to a load situation, for example), the PDP context may not deleted, but the registration is retried.

Title: Improvements in and relating to aircraft with autorotative wings
IPC: B64C27/02
Filed: 1935-01-16
Abstract: 452,397. Aircraft with rotarywing systems. LA CIERVA, J. DE., Bush House, Aldwych, London. Jan. 16, 1935, No. 1347/36. Divided out of 452,365. [Class 4] An aircraft having an autorotative sustaining rotor, includes means actuated by contact with whatever supports the aircraft at rest for decreasing the pitch angle of the rotor blades on landing or for applying a braking torque to the rotor on landing, the latter being combined with means responsive to the application of a braking torque to the rotor for decreasing the rotor-blade pitch angles. The invention is shown applied to a rotor assembly constructed and driven in the manner described in Specification 452,365. In this form, when the aircraft lands a projection 75 on the movable portion 73 of the landing gear forces upwardly a plunger 77 against a spring 78 to tension an element 80, 83 and apply a rotor brake 51 against the action of a spring 85. Movement of the lever 65 to engage a clutch, in the transmission to the rotor, through a tension element 66 withdraws a catch 87 against the action of a spring 88 and allows a plunger 82 to move under the action of the spring 85 in a cylinder 81 interposed in the element 80, 83 and release the rotor brake. The clutch is held in engaged position by a projection 91 which engages a spring-pressed catch 92 which is releasable by downward movement of the plunger 77 under the action of the spring 78 when the aircraft leaves the ground, or at the will of the pilot by a lever 98. In a modification the invention is shown applied to an aircraft in which the incidence of the rotor blades is adjustable mechanically at the will of the pilot. In this form, when the aircraft lands, a plunger 77 is forced upwardly to move a lever 101 clockwise against the action of a spring 102. The lever is connected by a spring-pressed catch 103 to a cam plate 107, clockwise movement of which against the action of a spring-pressed dash-pot piston 113 reduces the rotor pitch. A clutch in the rotor transmission is actuated by a lever 65 and is held closed by a projection 91 which engages a spring-pressed catch 92. The clutch is released for taking-off by depression of a lever 98 which withdraws the catches 92, 103 through, respectively, tension elements 96, 105. Release of the catch 103 allows spring 115 to actuate the cam 107 to increase the rotor pitch and, when the aircraft leaves the ground, release of the plunger 77 allows the spring 102 to return the lever 101 to its initial position. Specifications 420,322, 444,485, and 452,364 are referred to in the Provisional Specification.

Title: Improvements in or relating to rectifier powered equipments
IPC: H02M7/08
Filed: 1952-01-17
Abstract: 698,454. Rectifying. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Jan. 17, 1952 [Feb. 10, 1951], No. 1363/52. Class 38 (ii). [Also in Group XXXIX] The invention relates to a full-wave rectifying circuit suitable for use on a vehicle powered by D.C. motors, which comprises two rectifiers 21, 22 such as ignitrons connected respectively in the A.C. supply leads 21<SP>1</SP>, 22<SP>1</SP>, the supply circuit having such inductance that the commutation period extends over at least 20 electrical degrees whereby higher harmonics liable to cause telephone interference are reduced as described in Specification 682,610. There are connected across the supply leads firstly a capacitor C4p in series with a damping resistor R4p which capacitor is in resonance with the supply inductance at a frequency between the third harmonic of the supply current and 900, and secondly a capacitor C4s in series with an inductor L4s which elements are in resonance together at approximately that frequency. The series-resonant circuit reduces the lower order harmonics in the supply line which result from the parallel resonance. The reactor windings 21<SP>11</SP>, 22<SP>11</SP> are disposed together on the same core, which has an air-gap, in such a way that they present maximum impedance to a circulating commutating or back-fire current, and thereby provide inductance for producing the overlap and giving protection. Where there are several motors 1-6, each with its pair of reactors, these may have differing values so that they slightly displace the phases of the load currents to cause mutual cancellation of harmonics. The reactors also help to supply regulation and to equalize the loads. To throw the low order harmonics out of phase so that they tend to cancel more than one parallel resonant circuit may be provided for each motor. They may be connected in different ways, e.g. on the rectifier side of the reactor, as at 34, or the supply side, or with one end on each side, as at 36, 37, and tuned to different supply harmonics.

Title: Improvements in or relating to spindle coupling assembly
IPC: B21B35/14
Filed: 1957-01-14
Abstract: 809,347. Universal joints. KOPPERS CO. Inc. Jan. 14, 1957 [Jan. 12, 1956], No. 1363/57. Class 80 (2). Relates to a gear coupling connecting, e.g., a driving spindle 9 to the roller 6 of a rolling mill, and having internally toothed coupling sleeves 26<SP>1</SP>, 26, fast with the driving and driven members, engaged by externally toothed hubs 17, 18 fast with a connecting spindle 11, the coupling allowing misalignment of the driving and driven members. According to the invention, one of the pairs of co-operating sleeves and hubs 261, 18 and 26, 17 has at least one more tooth than the other pair, and one tooth on the hub 17 is in line with one tooth on the hub 18. With the aid of markings on the back face of the sleeve 26 and hub 17, assembly of the coupling without inching round either the driving spindle 9 or the roller 6 until the tooth gaps of the sleeves and hubs coincide, is made possible. In the form shown, the sleeve 26 fast with the driven roller 6 and the cooperating hub 17 have forty-two teeth, and the sleeve 26<SP>1</SP> and hub 18 have forty-one teeth. As shown in Fig. 7, the markings on the back face of the driven sleeve 26 coincide in number and position with the teeth within the sleeve 26, and the markings on the back of the hub 17 coincide in number and position with the teeth on the hub 18 at the other end of the spindle 11. The number 1 of the markings around the hub 17 is indexed with an arrow. An untoothed space 46 within the sleeve 26<SP>1</SP> is provided to receive the hub 18, so that the spindle 11 and hub 17 can be withdrawn rightwards of Fig. 1, to disengage the teeth on this hub from the cooperating teeth within the driven sleeve 26, when a roller 6 is to be changed. To reconnect the coupling, the spindle 11 is moved leftwards until the teeth on the hub 17 abut the teeth within the sleeve 26. It is then determined by inspection which of the numbers on the back face of the hub 17 most nearly coincides with a number on the back face of the sleeve 26, indicating the positions of the teeth within the sleeve. Having noted the number on the back of the coupling sleeve 26, the spindle 11 is moved rightwards to disengage the teeth on the hub 18 from teeth within the sleeve 26<SP>1</SP>. The spindle 11 is then turned until the number 1 on its back face, indexed by the arrow, coincides with the observed number on the scale on the back of the sleeve 26. The two sets of teeth within the driving and driven sleeves will then be aligned with their co-operating teeth on the driving and driven hubs, so that the spindle 11 can again be slidden to the left to engage both hubs 17, 18 with their sleeves. The hub 17 is retained within its driven sleeve 26 by a closure ring 32 held in position by a snap ring 42. The closure ring 32 contains a segmental sealing ring 36. Lubricant is introduced to the teeth of the coupling through a hole 31. Axial movement leftwards of the spindle 11 is prevented by replaceable abutting thrust buttons 22, 23.

Abstract: 441,349. Gun mountings. BIRKIGT, M., Rue du Capitaine Guynemer, Bois-Colombes, Seine, France. Jan. 16, 1935, No. 1517. Convention date, Nov. 20, 1934. [Class 92 (i)] A gun 1 is attached at one end to a support such as an aircraft engine 2 by means which are yieldable in the direction of the axis of the gun and so stressed initially that only abnormal recoil forces provoke substantial movement, the other end of the gun being guided by means 5, such as that described in Specification 414,300, which prevent lateral movement of the axis of the gun. The invention is shown applied to an aircraft gun firing through the hollow propeller shaft 4, Fig. 2, a spring 17 being arranged between a fixed bearing 6 and an adjustable collar 18 on the gun barrel. The spring 17 is preferably given an initial compression equal to five-thirds of the recoil force. Further, a second adjustable spring system 14 may be arranged between the bearing 6 and a collar 11 on the gun barrel to absorb shocks when the moving gun parts return to firing position. The spring abutments are so arranged that the spring systems 17, 14 do not react upon each other. Specification 441,350 also is referred to.

[Also in Group XXXVI] Separable contacts for fuses, switches or plug- and-socket connectors have the contact pressure augmented by a resilient member of helical, tubular or other hollow form in cross-section which is subjected to strain by way of inward lateral displacement tending to distort its crosssectional shape when the contacts are engaged. In the embodiment shown in Fig. 1, the limbs 18, 19 of a fixed U-shaped contact 11 loosely embrace a helical spring 22 lying with its axis parallel to said limbs so that on insertion into contact 11 of the limbs 12, 13 of a U-shaped removable contact 10, the spring is distorted into oval shape and reinforces the contact pressure. The contact 11 is held captive in a recess in a housing 23 by a cover-plate 24 and an insulating member 29 is disposed between the spring and the base of contact 11 so that current does not flow through the spring. The coils of the latter may be skewed in relation to its axis so as to limit the amount of pressure exerted by the spring. Fig. 4 shows another embodiment wherein a pair of springs 49, 50 operate between grooves 47, 48 in the walls of housing 41 and the outer faces of contact limbs 33, 34 to urge these limbs into engagement with a single blade contact 36. Alternatively, the fixed contact may comprise a pair of nested U-shaped members between the pairs of limbs of which fit the limbs of a U-shaped removable contact. The inner U-shaped member of the fixed contact may embrace a spring arranged as in Fig. 1 or springs as arranged in Fig. 4 may be provided outside the outer U-shaped member.
