Title: Method of measuring and controlling the level of liquid in a container
Inventor: WILSON JAMES HOWELL
IPC: G01F23/28
Filed: 1984-03-28
Abstract: A method is provided for measuring and controlling the level of an elevated temperature liquid in a container. The electrical voltage signal outputs of a plurality of temperature sensing devices at spaced elevations on the container are converted to digital form. The converted signals are periodically scanned in elevation sequence. A determination is made from the scanned signals of the location of the uppermost sensing means having a converted signal value of sufficient magnitude to indicate a temperature in the wall below the level of liquid in the container. Then a fraction, F, of the spacing between the sensing means, n, and the next above sensing means, n-1, is calculated as a function of the converted signal value, Sn-1. The measured level in the container is calculated as a function of, n, and, F, with respect to their location on the container. Finally, the rate of addition and withdrawal of liquid to and from the container is controlled based on the measured liquid level in the container.

Title: Catalyst system for the production of aromatics from aliphatic hydrocarbons
Inventor: KJELL SOLVEG S
IPC: B01J29/70
Filed: 1986-12-02
Abstract: Superior tolerance to catalyst coking in a process for production of aromatics from C₂ to C₅ hydrocarbons is obtained with a catalytic composite comprising a gallium component and a crystalline aluminosilicate zeolite incor­porated into a phosphorus-containing alumina matrix. A five-fold reduction in the coke content of the spent catalyst of the instant invention is observed which is directly attributable to the phosphorus-containing alumina matrix. A novel method of preparing this catalyst is presented, along with a novel process for the dehydrocyclo­dimerization of C₂-C₅ aliphatic hydrocarbons using this catalyst system.

Title: Carrier for stacked articles
Inventor: SCHUSTER RICHARD LEE
IPC: B65D5/46
Filed: 1993-09-29
Abstract: A carrier containing a plurality of layers of articles, such as beverage cans, arranged in stacked end-to-end fashion. The carrier is fully enclosed and is formed with overlapping top panel flaps which produce an area of double thickness between handle openings in the flaps. A reinforcing sheet on the underside of the top panel in the double layer area protects against tearing, while stress relief lines in the form of score lines extending from the ends of the handle opening to the corners of the carrier provide for distribution of lifting and carrying stresses. A separator sheet preventing direct contact between stacked articles extends between layers and may include distortable areas aligned with the articles. Downward pressure on the upper layer causes the bottom of an article to force the distortable area into a recess in the top of the next lower article.

Patent ZA-973572-B (ZA)
Title: Apparatus for reproducing a digital information signal from a record carrier
Inventor: ENDEN GIJSBERT JOSEPH VAN DEN
IPC: G11B20/18
Filed: 1997-04-24
Abstract: An apparatus for reproducing a digital information signal from a record carrier includes a read unit for reading a signal from a track on the record carrier, a bit detection unit for deriving the digital information signal from the signal read from the track in response to a clock signal and a phase locked loop for deriving the clock signal from the signal read from the track. The phase locked loop includes a phase comparator for deriving a phase error signal and a voltage controlled oscillator for deriving the clock signal. The apparatus further includes a sync pattern detector for detecting sync patterns occurring in the digital information signal and a counter for counting the number of bits occurring between two sync patterns in the digital information signal. If the number of bits counted between the two sync patterns exceeds a predetermined value (THR) by at least one, at least one additional bit is inserted into the digital information signal (an insertion error) and this at least one additional bit should be deleted from the digital information in order to keep the apparatus in synchronisation. When the predetermined number exceeds the number of bits counted by at least one, at least one bit was deleted from the digital information signal (a deletion error), so that at least one bit should be added in order to keep the apparatus in synchronization.
Patent GB-2358332-B (GB)
Title: Method of communicating data in a communication system
Inventor: ABBAS GHANI ABDUL MUTTALIB
IPC: H04J3/16
Filed: 2000-01-14
Granted: 2002-05-29
Abstract: The invention pertains to a communication system (300) including one or more communication channels (10), each channel comprising a transmitter unit (20) and a receiver unit (40). Each transmitter unit (20) is connected through an optical fibre link (30) to its associated receiver unit (40). In operation, each receiver unit (20) receives payload data from its associated sending client and adds overhead data to the payload data to generate corresponding aggregate data (600). The aggregate data of each transmitter unit (20) is conveyed through the fibre link (30) to its associated receiver unit (40) which receives the aggregate data, decodes it to separate the payload data from the overhead data and then outputs the payload data to its associated receiving client. The \receiver unit (40) interprets the overhead data and uses it for controlling and managing the payload data in the system (300). The one or more channels of the system (300) are capable of adapting to the bit data rate of their associate payload data; thus, the channels are capable of operating mutually asynchronously, thereby circumventing a need for justification in the aggregate data. Moreover, each transmitter unit (20) is operable to add the overhead data to the payload data when generating the aggregate data so that the number of payload bits relative to the number of overhead bits is in a fixed ratio of 31:1. Such a fixed ratio renders the aggregate data simpler to decode and bit error rate easier to determine therefrom.

Inventor: CLOUGH GEORGE FRANCIS GILBERT
IPC: B01D33/01
Filed: 1990-08-23
Granted: 1995-01-18
Abstract: Industrial filtration apparatus for the separation of solids entrained in a fluid stream comprises: a flexible perforate filtering sleeve closed at one end such that fluid can pass through perforations in the sleeve but entrained solids of a predetermined size are retained within the closed end of the sleeve. The apparatus has a structure for holding the sleeve about a discharge pipe for the fluid at a point between the closed and open ends of the sleeve, and for restraining movement of the sleeve away from the pipe; the apparatus is adapted such that in response to a predetermined fluid (e.g. hydraulic) pressure within the sleeve between its closed end and the discharge pipe, the closed end is allowed to be displaced away from the discharge pipe, thereby drawing a portion of the sleeve nearer its open end into a position forward of the pipe to expose said portion to the fluid stream.

IPC: C10G69/08
Filed: 1992-03-12
Abstract: A novel integrated olefin processing scheme is provided where olefins and paraffins are processed to produce high octane gasoline blending components. The integrated process involves the dehydrogenation of paraffin compounds to olefin compounds and the processing of olefins by hydroisomerization to produce hydroisomerate streams which are subsequently etherified. Those olefin compounds which are not etherified pass to an alkylation process where they are alkylated with branched chain paraffin compounds to produce an alkylate product.
