Title: 一种基于媒体网关控制协议的安全认证方法
Inventor: ZHENG ZHIBIN
IPC: H04L12/66
Filed: 2003-07-14
Abstract: 本发明公开了一种基于媒体网关控制协议的安全认证方法，该方法是：预先在媒体网关(MG)和媒体网关控制器(MGC)中设置MGC和对应MG的共享密钥K i ，MG和MGC之间进行安全认证时，MG和MGC分别利用双方确定的密钥生成算法、数字签名算法、MGC产生的随机数以及共享密钥，计算出本次认证过程中自身的签名字，然后通过将计算出的自身签名字和对方发送过来的签名字进行比较，以确定对方是否为合法方，从而完成对方安全身份的认证，该方法可确保非法媒体网关无法正确接入到媒体网关控制器中使用。

Patent GB-1053325-A (GB)
IPC: H04Q11/04
Abstract: 1,053,325. Automatic exchange systems. SIEMENS & HALSKE A.G. Aug. 20, 1964 [Aug. 20, 1963], No. 34087/64. Heading H4K. In a time division multiplex PABX system in which the addresses of a calling and a called party are stored in respective circulating stores at a time slot allotted to the connection between the parties, either party may initiate a call-back (interim, conference or transfer call) by transmitting a signal to a central control system of the exchange whereafter the relevant party inserts the address of the called-back party into a further circulating store at the same time slot. A (called) station N1 engaged in a connection with a (calling) exchange line ALx at time slot P1 initiates a call-back by depressing a special key whereby when an address register AZ next provides at its output for one multiplex cycle N1's address, central control StE detects a change in state of line circuit T1 and allocates a digit receiver Zi to N1. A pulse is entered in RB at P1 to indicate that a called party at P1 has initiated a call-back. The address of the wanted party is entered in Ua (normally a calling party store) at P1. By means of circulating stores Uda, Udb, Udu, Udp, the switches Sp1 to Sp4 are controlled so as to allow or prevent, as the case may be, the transmission of an address between stores Ua to Up and decoders Da to Dp. Thus if the pulse at P1 in Udu is erased (as would normally be the case for the interim call described above) then the exchange line cannot take part in the callback since switch Sp3 is open at P1 whereby speech switch SAx cannot be closed.

Abstract: 1,053,335. Primary cells. P. J. TAMMINEN March 11, 1964 [March 11, 1963], No. 10341/64. Heading H1B. A primary battery is made by assembling a stack of flat cell elements of substantially the same major dimensions, coating them with an insulating material in a solvent whilst holding the stack under pressure, evaporating some of the solvent in a vacuum until a sticky residue is left, releasing the vacuum so that the coating penetrates into the mix cake and the joints between the parts, and evaporating the remaining solvent to leave small holes in the coating at the mix cake surfaces. The soprepared battery can be impregnated with water and coated in an impervious manner. By this means a greater quantity of water can be incorporated into the battery than could be done if it were to be introduced into the mix initially, with increased efficiency.

The reactions are carried out under anhydrous conditions in an organic solvent which may be an acyclic ether, e.g. diethyl ether or the dimethyl ether of ethylene glycol or a cyclic ether, e.g. tetrahydrofuran and at a temperature of 50-150‹ C., e.g. reflux temperature. The compounds, which are used as additives to lubricant compositions comprising a polyphenyl ether or polyphenylpolyether or a mixture of both, may be bisdiphenyltin, dinaphthyltin, diterphenyltin, diphenanthryltin, dianthryltin, diacenaphthyltin, and biphenylylnaphthyl tin.

Abstract: 1,084,099. Automatic exchange systems. WESTERN ELECTRIC CO. Inc. Dec. 21, 1964 [Dec. 20, 1963], No. 51862/64. Heading H4K. In a system which includes a PBX 130 attached to a main office 110, an incoming call to a PBX subscriber may be transferred to a second PBX subscriber, to a main office subscriber, or even to a subscriber connected to another main office 140 by the transmission of VF pulses to the main office. As shown, the main offices 110, 140 are of cross-bar type, while the PBX 130 uses step-by-step switching. An incoming call to trunk circuit 113 is extended to a PBX subscriber 101 with the assistance of a dial pulse sender 126. If the call requires transfer, the subscriber actuates his switchhook, and the circuit 113 responds by recalling the marker (not shown) which sets up a fresh connection to a transfer trunk 116 and transfer register 118. On receiving dial tone, the subscriber dials into a dial tone pulsing circuit 136 which converts each pulse into H3, L4 tone (Fig. 3) to set the register 118. The latter is capable of responding either to tone pulsing of this kind, or to frequency-sending, in which each digit is denoted by a pair of frequencies (Fig. 3). Meanwhile, the incoming trunk 113 has been connected via the transfer trunk 116 to the PBX 130 and a sender 126 is taken into use to set up the connection required, e.g. to 102. If no reply is received, the call may be further transferred to another subscriber or to an attendant's position 131. The call may be similarly transferred to a subscriber 104 connected to the main office 110, or to one 103 connected to another main office 140, but in the latter case a multifrequency sender 123 is taken into use instead of the dial pulse sender 126. A call directed to the subscriber 103 may also be transferred, if necessary by the use of a dial tone pulsing circuit 146 similar to 136.

[Also in Division G4] In apparatus for measuring the rotational speed of a turbine shaft by measuring the frequency at which the turbine compressor blades 12, which are electrically conductive, pass a transducer 10 mounted on the housing 14, the transducer 10 comprises a permanent magnet 28 mounted on a central magnetic core 24 within a magnetic housing 18 to form a magnetic circuit having an air gap that the blades 12 pass through and a pick-up coil 32 wound on the core 24 for detecting changes in flux caused by eddy currents induced in the blades as they pass the transducer.

Abstract: 1,227,507. Stretching and testing fabrics. RADUNER & CO. A.G. 27 Oct., 1969 [31  Oct., 1968], No. 52537/69. Addition to 1,140,030. Heading D1S. A fabric web 10 continuously advancing in its warp direction is subjected to a multiplicity of closely spaced laterally aligned sets' of stretching forces to continuously transversely elongate the fabric in the weft direction and the transversely elongated web is continuously scanned to detect the presence of any fabric splits. The fabric 10 is stretched by a pair of meshing grooved rolls 50 as described in the parent specification. The fabric is scanned by an ultrasonic unit comprising a pair of 25 KC transducers 47 mounted within and at each end of a sound-reflecting metal trough 48 the lips of which are located close to the rolls 50. The trough 48 is mounted on arms 51 pivotally attached by straps 52 to a tie bar 53. The arms 51 are provided with depending legs 54 pivoted to a rod 55. The lower ends of the legs 54 are maintained spaced by a tie rod 56. At startup, the legs 54 are displaced to permit the arms 51 to pivot downwardly to allow the fabric 10 to be threaded through the unit. The transducers 47 detect the sounds of any fabric splits and produce a voltage signal which is applied to an amplifier to operate, any or all of, a warning signal, a fabric marker or a machine controller. The fabric may be of natural or synthetic fibres or a blend thereof and may be wet or dry and with or without chemical treating materials, e.g. dyes, cross-linking or swelling agents. However, stretching should take before a dimension stabilizing treatment.

Abstract: 1,228,237. Catalysed oxygen consumption in molten electrolyte fuel cells. BOLT BERANEK & NEWMAN Inc. 11 June, 1968 [9 Aug., 1967 (2); 20 March, 1968], No. 27752/68. Heading H1B. In an electric cell wherein continual peroxide or superoxide formation is effected during operation of the cell by supply of oxygen, with agitation, to a fused electrolyte in the cathode region of the cell, the peroxide or superoxide formation is catalysed by addition to the electrolyte of a compound of a metal of Group VIII of the Periodic Table or of Mn, or of a boron compound giving rise to a borate or perborate. In examples cells using a Pd hydrogen anode and a Ni cathode in a 90/10 mixture of KOH/Na- OH at 460-500‹ C., improved oxygen utilization and power density, together with reduced deposition of Ni at the anode and Ni 2 O 3  at the oxygen inlets, were obtained by adding CO 2 O 3 , MuO 2  or Fe 2 O 3  or Co(NO 3 ) 2 .6H 2 O; and improved power density and dependence thereof on O 2  partial pressure were obtained by addition of K 2 B 2 O 7 , H 3 BO 3  or Na 3 BO 3 .
