Abstract: 一种无线自组织网络中保障寻径可靠性的方法，利用特殊的报文格式在无线自组织网络中传输路由请求报文，使接收结点可以根据识别的报文片断来判断是否存在路由请求报文由于报文冲突或噪声干扰被毁坏或丢失，并在发现路由请求报文丢失时立即通知相关结点重发该报文，从而保障寻径过程的可靠性和有效性，使路由协议能尽快找到尽可能多的可选路径，以便做出最佳的路由选择。该方法对路由请求报文的识别在物理层或者数据链路层完成，正常接收的情况下不需要发送确认信息，从而最大程度地减少了对网络资源和系统资源的使用。另外，相对传统的超时重传机制而言，该方法可以更快地发现路由请求报文的丢失并重传该报文。

Abstract: The invention relates to a method and a communications network of updating a domain name server's (DNS) routing data when a second mobile terminal (TB) that has been the customer of a second operator's communications network (OPB) changes operators becoming the customer of a third operator's communications network (OPC) while retaining the telephone number. In the method, the third operator submits a transfer request for the change of the second mobile terminal's (TB) operator to a database server (DB), after which the time-to-live of the responses given to the enquiries sent to the domain name server (DNS) is reduced stepwise down to a predetermined maximum value. After this, the database server (DB) updates the domain name server's routing data in respect of the second mobile terminal (TB) to indicate the third operator's data communications network (OPC) and changes said time-to-live back to original.

IPC: B03C1/14
Abstract: 1,051,794. Magnetic separators. ERIEZ MANUFACTURING CO. Jan. 29, 1965, No. 4017/65. Heading B2J [Also in Division H1] In a magnetic drum-type separator having a shell made of non-magnetizable material rotatably mounted on a stationary shaft, a number of pole assemblies 110-113, Fig. 3, are secured inside the shell to a back plate 102 of magnetic material fixed to the shaft 105 and extend radially outwardly to the vicinity of the inner periphery of the shell. Each pole assembly comprises one or more stacks, e.g. 121, 122, of magnetic units 125 each of which has a greater dimension in length and width than in thickness. In the or each stack the units are arranged with their major faces in abutting relationship. The units in each assembly are magnetized permanently in the same direction. which direction is substantially normal to the major faces of the units. As shown, the back plate 102, which may be of steel, has welded thereon upstanding projections 102a which are detachably secured to support plates 104 axially spaced along the shaft and provided with hubs 106, 107 for the passage of the shaft. The pole assemblies are of alternate polarity. The units 125, which may be of a non-metallic material comprising a magnetized ceramic, e.g. barium ferrite, are held together on flat portions 130, 131 of the back plate 102 by means of plates 135-138 of non-magnetizable material and threaded bolts 140. Non-magnetizable holding plates 141, 142 may be provided on the endmost faces of the pole assemblies 110, 113. In a modification, Fig. 4 (not shown), the magnetic units 125 are held by means of channelshaped covers 150 of stainless steel bolted to the backplate 149. In the arrangement of Fig. 1 the drum 11 is driven counter-clockwise by means of an electric motor 18 through a chain 17 and a sprocket 15 and is spaced from a plate 41 defining a chamber 40 to which is fed. through an opening 39, in the plate 41, a slurry of material 35 to be separated. The material is delivered to a chamber 36 to which water is fed at 37 to form the slurry. Non-magnetic constituents 52 of the material are discharged, via an opening 50 in the plate 41, into a chamber 51 and are removed at 54. The magnetic constituents are attracted to the outer surface of the shell-and are carried thereby past the pole 29 of the permanent magnet 20 to fall off, or to be scraped off, into a chute 55. A baffle plate 45 defines an overflow chamber 46 for excess water which is removed at 48. Fig. 2 (not shown) relates to a slightly different arrangement in which the separator drum is rotated clockwise. Separators for dry separation may be similarly constructed.

Abstract: 1,053,230. Transistor pulse generating circuits. HEWLETT-PACKARD CO. Dec..31. 1963 [Jan. 11, 1963], No. 51448/63. Heading H3T. A pulse generator comprises a short-circuited transmission line 39 connected to a load 41 and two further transmission lines 35, 37 each comprising one conductor of line 39, also connected to the load 41 and means for propagating voltage steps along lines 35, 37. As described, the conductive states of transistors 9, 13 forming a Schmitt trigger, is reversed each time an alternating voltage at the input terminals passes through a reference level. Voltage steps of opposite polarity are thus fed to transistors 27,-29 which propagate corresponding voltage steps along lines 35, 37. The impedances of the lines are such that on reaching the load 41 the voltage steps initiate a half-amplitude pulse across the load 41 and further voltage steps are reflected from right to left along lines 35, 37, 39. The impedance of transistors 27, 29 is much greater than that of lines 35, 37 hence the steps will be further reflected along these lines without change of polarity. The steps on line 39 will be inversely reflected by the short circuit at the left-hand end. When the voltage steps reach the load 41, cancellation occurs, terminating the pulse. The pulse duration is thus equal to twice the transit time of the lines. When using the impedance ratio shown, the impedance presented by the lines to transistors 27, 29 will be eight times the impedance of load 41.

Abstract: 1,085,350. Flame detecting electric circuits. DANFOSS A/S. Aug. 9, 1966 [Aug. 11, 1965], No. 35632/66. Addition to 1,056,625. Heading F4T. In an improvement in or modification of the flame control apparatus of Specification 1,056,625 the apparatus has, in addition to the flame electrode, an ultra-violet radiation sensitive discharge tube 27 shunted by a rectifier 28 and arranged in a circuit to control the diode 10 and cause it to conduct when current is passing through the tube.
Patent GB-1114372-A (GB)
Abstract: 1,114,372. Removing filter cake. SIMONACCO Ltd. 5 July, 1965 [14 July, 1964], No. 29201/64. Heading B1D. In a method of filtering using a rotating sectorial vacuum drum filter described below, the filter cake is blown off each sector 16, Fig. 2, once only in a plurality of revolutions of the sectorial drum 16. The cake may be blown off all the sectors in one revolution e.g. every 7th revolution, or off different sectors in successive revolutions. The arrangement is such that as the sectors 16 rotate, vacuum is applied to them while they are immersed in the slurry, and filter cake is blown off by compressed air supplied to the interior of the sector while it is outside the material. The filter comprises a tank (12) for slurry to be filtered, hollow sectors 16 of filter drum 14 which are partially immersed in the slurry in the tank as they are rotated during filtration. each sector having perforated faces and covered by filter cloths, means for applying vacuum to the interior of each sector via vacuum boxes 66, (68), apertures 78, 80 and 82 in stationary plate 60, Fig. 4, apertures 46 in rotating plate 39, and connecting pipes 44 and apertures 48 contained in rotatable cylinder 32, means for supplying compressed to the interior of each sector via a control valve (90) pipe 86 aperture 84 in plate 60, apertures 46 and pipes 44. The blown off cake is guided by plate (22), (24) into chutes (18), (20). The sectors are described in Specifications 870,769 and 894,318.
Patent GB-1225589-A (GB)
IPC: D01D5/42
Filed: 1969-04-25
Abstract: 1,225,589. Bulked yarns; fibrillated. AVISUN CORP. 25 April, 1969 [26 April, 1968], No. 21281/69. Headings D1F and D1W. A process for continuously producing bulk yarn from molecularly orientable polymeric material comprises the steps of extruding the polymeric material into a film-like web 11, longitudinally drawing the web to stretch the same to an orientation point at which filamentization is possible, slitting the web into a plurality of individual flat ribbons R 1  to R n , passing the ribbons through a heating zone Z 1  to Z n , and false-twisting each of said ribbons to fibrillate the structure thereof to form a yarn composed of twist-free, continuous filaments. In an alternative embodiment, the web is slit into ribbons before orientation, the width of the ribbons being appropriate to the denier of the final yarn. The polymeric material may be polyethylene, polypropylene, polyamide, or polyester.
