Patent CA-1334784-C (CA)
Inventor: HERBORT HANS-JOACHIM
IPC: C01B3/02
Filed: 1988-06-10
Granted: 1995-03-21
Abstract: The invention relates to a process for the production of ammonia from natural gas, liquified petroleum gas, naphtha or hydrogen-bearing gases, using a combined autothermic reforming process and feeding a separate oxygen stream and a separate stream of pre-heated air to the system.  The aim of the inven-tion is to design an economical and simple configuration which reduces the oxygen requirement substantially.         The aim of the invention is achieved by implementing various process steps some of which are already known and by combining them in such a manner that, in addition to the atmospheric oxygen, a separate oxygen stream with a min. O2 concentration of 50% is admixed, the concentrated O2 stream being pre-heated to a max. temperature of 250°C and the atmos-pheric air stream to approx. 450 to 900°C, and the H2/N2 ratio required at the outlet of the reforming section being adjusted with the aid of the atmospheric air stream and the make-up oxygen stream.

Title: Apparatus for real time data compressor
Inventor: FROST RICHARD L
IPC: H03M7/30
Filed: 1988-06-24
Granted: 1993-01-19
Abstract: ABSTRACT OF THE DISCLOSURE        High speed computing apparatus is provided for performing real time data compression of analog voice data or digital data to be transmitted over a data link.    The incoming  data  stream  is  divided into blocks of digital data and the blocks are subdivided into digital samples or elements  to  be  compressed.  Each  sample  is analyzed individually to determine its estimated variance  and  the marginal return to be gained by alloting the sample one or more of the bits to be employed to define  the  block  of digital data.  The bits are assigned to the samples having the highest estimated variance factor so that  an  optimum allocation  of bits to individual samples is achieved with variable ratio data compression.   The allocated bits  are employed  to  encode  the  samples  during  real time data compression and transmission.

Abstract: ABSTRACT            BIT SYNCHRONISATION FOR OPTICAL NETWORKS     A submarine optical telecommunications system has two shore based transmitting stations whose signals are combined at a passive, submerged junction.  Phase errors are caused by variations in transmission times to the junction.  an error signal is generated at the first repeater after the junction.  The error signal, which represents the phase errors, is transmitted to a shore station where it is used to adjust the sending phase.  A surface acoustic wave filter tuned to half the frequency of the combined signal is the preferred way to generate the error signal.

Title: Remote test access system for isdn testing
Inventor: CHAN WING-MAN
IPC: H04Q11/04
Filed: 1989-04-21
Granted: 1995-06-06
Abstract: Conformance with established standards and interoperability between products in an integrated services digital network (ISDN) system defined by a layered hierarchy of interrelated protocols is ascertained by remotely testing the protocols between a tester in a local testing centre and a system under test located at a geographically removed site.          The protocols tested relate to the first three layers of the system which are concerned mainly with the establishment, holding and release of a telecommunications path.   Cost effectiveness in product testing is achieved by accessing both the tester and the system under test and communicating test procedures between the local and remote sites over a packet switching network to support testing at the remote site.          Communications over a virtual circuit in the network are established between a pair of remote ISDN test access interfaces, one located at each site.  A communications path from a test access interface and its corresponding local tester or system under test is provided by an ISDN interface.  Under software control by a computer at each site, the test access interfaces function individually to split the corresponding ISDN interface so that the network may be inserted therebetween to link the tester with the system under test.

Abstract: ABSTRACT A communication system develops an information packet having a packet structure field and at least one message. The message has an address and information associated with the address. A central station accumulates and incorporates the at least one message into the information packet. The central station determines the occurrence of the at least one address and generates identifying data indicating where the address occurs within the information packet. The identifying data is incorporated into the packet structure field and the information packet is transmitted. The information packet is received by at least one selective call receiver capable of operating in a high power mode in order to receive the information packet and a low power mode when receiving is not being performed. The selective call receiver extracts the packet structure field and interprets the identifying data. The idenifying data is used to operate the selective call receiver in the high power mode only during the occurrence of the at least one address. The selective call receiver operates in the low power mode for the remainder of the information packet unless the information associated with the address is intended to be received by the selective call receiver.

Abstract: ABSTRACT OF THE DISCLOSURE     A spool for winding thereon a flexible elongate material includes a hollow cylindrical body having an elongate radial opening defined axially in the annular peripheral wall of the spool body for providing a passage of a holding means for automatically holding a leading end of the elongate material on the spool body.  A winding apparatus includes a pair of oppositely disposed first and second drive shafts for holding the spool therebetween.          The holding means is associated with the first drive shaft and cooperative with the radial opening in the spool body in effecting the holding of the leading end.  The holding means is either the pneumatic  type or the mechanical type.          The pneumatic holder means produces a negative pressure in the axial hole in the spool body to create a suction force acting around the radial opening in the spool body.  Due to the negative pressure thus produced, the leading end of the elongate material is sucked toward the radial opening and then adhered to the annular wall of the spool body. The mechanical holding means includes a row of locking needles movably mounted in an end portion of the first drive shaft so as to selectively project outwardly beyond the annular wall through the radial opening of the spool body.

Abstract: In the field of security validators, slot acceptors have been known which transport paper offered as a valid security past a testing station. Previously known acceptors have been susceptible to defeat by mosaics, stringing, shocking, photocopy duplication, and the like. Additionally, known acceptors have operated in an analog mode, relying upon rudimentary test functions. The invention herein overcomes the problems of the prior art by presenting an acceptor having a note path (18) characterized by changes of direction (22, 24), and which is secured at each end by means of unique gate assemblies (78, 98). A plurality of sensors (148-152) are positioned along the note path and are controlled to take a multitude of data samples from the paper as it passes along the path. The data is digitized (236) and used for solving complex transforms, the results of which are compared against results obtained from known valid securities to determine the authenticity of the paper offered. Further, the system includes a unique antijamming technique of drive motor reversals, and an escrow feature which secures the paper once it has been determined to be authentic and before a vend has been made. Yet further, there is included a novel receptacle for receipt and return of paper offered to the acceptor, and a number of variations of anti-stringing devices (112, 114, 118, 130) which may be operatively positioned at the end of the note path.

Abstract: A device for fastening together the parts of a heat-insulated composite section consisting of two metal sections and of at least one insulating rod has knurling rollers that shape exterior groove webs, forces them against the insulating rod, provides them with a knurled strip. The knurling roller has conical, toothed, circumferential surfaces. The bottom land between each pair of teeth parallels the conical circumferential surface. The knurling rollers are mounted in a tensioning mechanism that consists of two annular disks in such a way that it can be displaced along its axis. It can be displaced 0.5 to 1 mm to each side out of an intermediate position. The axial flotation make it possible to compensate for errors in alignment between the knurling roller and the composite section that occur while the groove webs are being shaped as a result of undesirable superimposition of the tolerances of the separate parts. The knurling rollers are mounted in such a way that they cannot rotate on powered shafts. They advance the composite section, which is also guided by horizontal and vertical guide rollers, through the device.
