Title: Method for anaerobic treatment of high strength liquors
Inventor: HOFFMAN CLARENCE ANTHONY
IPC: C02F11/04
Filed: 1986-08-05
Abstract: A process for the treatment of high strengfh BOD containing liquors (1) involves mildly mixing and contacting the liquors with anaerobic bacteria (2) and a powdered adsorbent support medium (4), such as activated carbon, to remove a substantial portion of the organic matter and generate a methane fuel gas (3). Use of the powdered support medium at 0.1-20 g/l enables high removal of BOD in short treatment times of 72 hours or less, rapid clarification of treated liquors, and increased adsorbability of liquor colour. The biomass and adsorbent support medium (8) is separated from the digested liquor (7) and at least part (9) thereof is returned to the anaerobic digester (2). Another part (11) may be treated to regenerate the support medium (13) for re-use. The digested liquor (7) may be further contacted with reduced concentrations of powdered colour adsorbent (15), which may also be activated carbon, to produce a treated liquor (18) low in dissolved organic matter and colour, and the spent powdered colour adsorbent (19) is preferably regenerated (37) and re-used.

IPC: D21H21/22
Filed: 1997-08-19
Abstract: Fibrous cellulose materials useful in the manufacture of soft, absorbent paper products such as paper towels, facial tissues, and toilet tissue are disclosed. The paper products contain a vegetable oil based quaternary ammonium chemical softening compound. Examples of preferred vegetable oil based quaternary ammonium chemical softening compounds include diester di(oleyl)dimethyl ammonium chloride (DEDODMAC) (i.e., di(octadec-z-9-eneoyloxyethyl)dimethyl ammonium chloride) derived from canola oil and/or high oleic safflower oil.

Title: Sand reclamation.
Inventor: SIMPSON ROBERT
IPC: B22C1/22
Filed: 1997-10-31
Abstract: A carbohydrate is added to sand, which has been used to make foundry moulds or cores, and which has been bonded using an alkaline resol phenol-formaldehyde resin, prior to reclamation of the sand by a thermal reclamation. The thermal reclamation may be done in other equipment, for example, a rotary thermal reclamation unit, but is preferably done in a fluidized bed reclamation unit. The carbohydrate is preferably water soluble and is added to the used sand as an aqueous solution. The carbohydrate may be for example a monosaccharide, such as glucose, mannose, galactose or fructose, or a disaccharide such as sucrose, maltose or lactose. The carbohydrate may also be a carbohydrate derivative such as a polyhydric alcohol (e.g., ethylene glycol, glycerol, pentaerythritol, xylitol, mannitol or sorbitol), a sugar acid (e.g., gluconic acid), or a polysaccharide derivative (e.g., a starch hydrolysate, i.e., a glucose syrup or a dextrin). The amount of carbohydrate used in the reclamation process is usually of the order of 0.25% to 5.0% by weight based on the weight of used sand.

Abstract: A portable storage device, for example a secure smart card, contains network identification information for a processing unit that is connectable to a data communications network, which processing unit includes a device reader for reading the portable storage device. The portable storage device includes storage and an access controller. The storage holds a network identity for the processing unit and at least one encryption key. The access controller is operable to control access to the storage by implementing key-key encryption. An embodiment of the invention thus provides a medium not only for storing a network identity for processing unit, but also for other secure information such as an encryption key associated therewith. The processing unit is operable to access a secure portion of the storage of the portable storage device by supplying a request key to the access controller of the portable storage device, and, in response to receipt of an access key from the access controller, to send an encrypted command to access the content of the storage of the portable storage device. In response to the return of an access key, the processing unit can be operable to use the access key to encrypt a command for access to a secure storage in the portable storage device.

Abstract: In an optical transmission system, an optical terminal transmits a plurality of tone signals corresponding to a plurality of gain bands, where the frequencies of the plurality of tone signals are different from each other, and each of the plurality of tone signals has a characteristic which is varied according to detected power of optical signals in the corresponding gain band. Each optical repeater receives the plurality of tone signals, extracts the characteristics of the plurality of tone signals, and compares a signal representing each characteristic with a reference signal. The optical repeater controls the gains of optical amplification in the plurality of gain bands based on the comparison result so as to equalize the gains in the plurality of gain bands.

IPC: H04L47/2491
Filed: 2002-09-19
Granted: 2004-01-14
Abstract: An identifier distinguishing unit 14 distinguishes what the identifier contained in a packet is. A VC search processing unit 13 searches the identifier/VC management table 12 using that identifier as the search character sequence. A VC selecting unit 15 selects an ATM VC for use in transmission on the basis of the ID information on ATM VCs resulting from the search. A cell formation processing unit 16 subjects the packet to ATM self format conversion processing. A frame formation processing unit 24 regenerates individual packets from packet information. A VC distinguishing unit 25 distinguishes the ID information on ATM VCs pertaining to each individual packet. An identifier search processing unit 23 searches the VC/identifier management table 22 using the ID information on ATM VCs as the search character sequence. An identifier assigning unit 26 assigns the identifier resulting from the search to the packet, and supplies that packet. This makes it possible to comprehensively manage packets transferred across a plurality of packet networks having different identifier management policies.

Title: Inactivity monitoring for different traffic of service classifications
Inventor: ERIKSSON GOERAN
IPC: H04L12/56
Filed: 2007-04-17
Granted: 2010-10-20
Abstract: Different types of traffic requiring different inactivity timer settings are assigned to different bearers or to different QoS classes. Different inactivity timer settings are established for different traffic types. Individual bearers or individual QoS classes are linked to a corresponding inactivity timer profile. The link may be accomplished in a number of ways. For example, an additional QoS parameter may be employed in a 3GPP QoS profile, or a new QoS class identifier may be mapped to an inactivity timer setting. Different inactivity timer settings allows both UE battery power conservation to be prioritized for some traffic and end-user experience (quick subsequent response times) to be prioritized for other traffic.
