Title: Aerosol compositions containing encapsulated insecticide in the dispersed aqueous phase
Inventor: HASSAM DEAN ANTHONY
IPC: A01N53/08
Filed: 1996-10-09
Abstract: An insecticidal composition in the form of an aerosol water-in-oil emulsion is disclosed which comprises:  (a) an amount of an aqueous suspension of microencapsulated insecticide to give an insecticide concentration in the composition of from 0.001 to 5% w/w; (b) one or more solvents in an amount of from 1 to 20% w/w; (c) one or more emulsifiers in an amount of from 0.2 to 10% w/w and selected from the group comprising mono-, di-and tri-sorbitan esters, polyoxyethylene sorbitan esters, mono- and poly-glycerol esters, ethoxylated nonionic emulsifiers, propoxylated nonionic emulsifiers and ethoxylated/propoxylated nonionic emulsifiers; (d) from 2 to 80% w/w of one or more propellants; (e) optionally from 0.001 to 5% w/w of one or more oil phase soluble insecticides; and (f) the balance being water.  Whereas incorporation of microencapsulated insecticides, particularly microencapsulated insecticides that are aqueous dispersions or suspensions into aerosol compositions has been known to be problematic owing to the instability of the so-formed emulsions (this instability has been attributed to the fact that the microencapsulated insecticide is present in the dispersed aqueous phase rather than the oil phase as occurs with conventional water based aerosol insecticides), the particular emulsifiers in the present compositions act to stabilise the compositions without impairing insecticidal effectiveness.

Title: Band selection using a fixed filter or parallel switchable filters and a mixer at the input to select the desired signal
Inventor: SCHERER DIETER
IPC: H04W88/08
Filed: 1997-11-11
Abstract: Transmit and receive programmable band select/transfer modules are programmable to select spectral segments and translate the frequency of the selected segments to designated spectral positions in the output signal. Each module shifts the frequency of an applied ~wave signal 6 to dispose a predetermined spectral segment about an IF frequency. The predetermined spectral segment is then selected using a fixed frequency filter at the IF frequency. The spectral segment has one of several bandwidths, selected by one of multiple fixed frequency filters in the modules. The module translates the frequency of the filtered spectral segment to dispose the selected spectral segment about an output frequency to provide the output signal. An optional pilot signal or service channel may be summed with the filtered spectral segment prior to the frequency translation. Use in a local multipoint distribution service (LMDS) is described.
Patent GB-2317543-A (GB)
Title: Virtual network architecture
Inventor: HART JOHN
IPC: H04L12/46
Filed: 1996-07-12
Abstract: Network traffic management is achieved based on automatically setting up a plurality of virtual networks (VNETs) (27) within a single large virtual LAN (35). Mulicast/broadcast traffic (211) is confined to the VNET (27) of the source, without imposing constraints on layer two addressing within the virtual LAN. VNETs (27) are domains of users of a virtual LAN (35) which include members of logical networks defined at layer three or higher. One method includes transferring a multi-destination packet originating from a particular node in the virtual LAN (35) by a point-to-point path to a virtual net server (106). The virtual net server (106) translates the multi-destination packet to a plurality of directed messages identifying nodes authorized to receive multi-destination packets from members of the particular VNET (27) which originated the packet. The directed messages are then forwarded from the virtual net server (106) to the authorized nodes. This way, multi-destination packets, such as advertisement or discovery packets, are confined to a single VNET (27). By confining the mult-destination packets to a single VNET (27), unicast packets generated within the virtual LAN (35) are then also then also naturally confined to that VNET (27).
Patent GB-2338844-A (GB)
Title: Interface for by-passing a failed uninterruptible power supply
Inventor: JESSE PETER
IPC: H02J9/06
Filed: 1998-04-03
Abstract: In an on-line type interruptible power supply system in which the UPS receives power from a mains supply at L1, N1 and normally provides an output at L4, N4 for a load, and the UPS continues to provide power for the load on interruption of the mains supply L1, N1, an interface circuit is provided which connects the mains supply L1, N1 directly to the load L4, N4, by-passing the UPS, in response to sensing failure of the supply of current from the UPS. The interface circuit may have a relay with a coil R connected across the output L3, N3 from the UPS, so that when the UPS is operating normally the coil R is energised to open normally-closed contacts of a switch R1 and to place a changeover switch R2 in a state connecting the load line terminal L4 to the output terminal L3 of the UPS. If the UPS fails, relay R drops out, so that switch R2 connects load terminal L4 directly to mains line terminal L1, by-passing the UPS, and switch R1 closes to connect a warning alarm buzzer AL across the mains L1, N1. The circuit may be locked into the by-pass state by operation of a switch SW to allow replacement of the failed UPS. When the replacement UPS has been connected, the switch may illuminate to indicate that the UPS is operating correctly. An equivalent solid state circuit may be used instead of the relay-controlled circuit.

Title: Thermosensitive recording method wherein a substrate is rolled back from a wait position to a print start position during a warm up operation of a printhead
Inventor: TAKEDA KAZUHIRO
IPC: B41J2/38
Filed: 1999-03-12
Abstract: A thermal printer includes a recording controller 1 and a sensor 3 which detects the temperature of a thermal printhead 2 prior to a print operation. If the temperature is below a first threshold value (e.g. 25{C), then a warm-up operation is performed by the controller to heat the printhead whilst a leading edge of a substrate (e.g. paper) is rolled back from a wait position 7 to a print start position 8. If the detected temperature is below the first threshold value but above a second threshold value (e.g. 20{C), then the paper is fed at normal speed and the printhead is controlled to print thereon at a normal print energy level. If the detected temperature is below the second threshold value, then either the paper is fed at a low speed and the printhead is controlled to print on the recording paper at a normal print energy level; or the paper is fed at the normal speed and the printhead is controlled to print on the paper at a higher print energy level.

Title: Extraction of aluminum and titanium
Inventor: OMOYIOLA BAMBOUR OLUBUKOLA
IPC: C25C3/00
Filed: 1999-06-25
Abstract: The non-suitability and inadequacy of conventional thermal reduction utilising carbon for the extraction of metals such as Titanium, Chromium and Vanadium is a point of focus in this invention principally because the end products are carbides of these metals and not the metals as would be expected.,wherein attention is drawn via this invention of a contemporary process involving the electrolytic extraction of titanium, chromium and vanadium as well as other metals from an electrolytic production cell utilising and comprising a mixture of high and low melting point carbides, hydrides, borides, nitrides, silicates and sulp hides. Aluminium and titanium are obtained by electrolytic extraction using, as electrolyte, a mixture of high and low melting point carbides, the high melting point carbide being either aluminium carbide or titanium carbide and, as anode, graphite and/or carbon. The low melting point carbide may sodium carbide, calcium carbide or selenium carbide. In a further embodiment a metal is produced by reaction of metallic carbides with metallic hydride. Specifically titanium is produced by reaction of titanium carbide with titanium hydride.
