IPC: G01R31/42
Filed: 1998-09-02
Abstract: In low-power AC networks, it is desirable when a load is connected,  for example an arc furnace or a vehicle, to know the load capacity of the AC network in order to avoid undesirable drops in the network voltage U N. TO this  end,  load  voltage  signals  which  are proportional to the amplitude of a load voltage U L are detected at the point of the load L at a 1st measurement time which can be predetermined and at a 2nd measurement  time  which  can  be  predetermined  and  is later.  At  the  same  time,  load  current  signals  are detected which are proportional to the amplitude of a load current I L. Furthermore, a phase difference .DELTA..PHI. is determined,  which  is  obtained with  reference  to  the phase angle of the network voltage U N at the 1st measurement time. These measurements are used as the bases to calculate a magnitude of the network impedance of the AC network and the network phase angle .PHI.N between the network voltage U N and the network current. A maximum possible power P L of the load L can be calculated in accordance with P L = U L2 ~ COS .PHI.N/Z N, where Z N = network impedance.

Title: Apparatus and method for providing large inflated undulating figures
Inventor: DRANGER ARIEH LEON
IPC: G09F15/00
Filed: 1997-07-03
Abstract: This invention is an apparatus (20) and method for providing a dynamic gas inflated object such as a figure (40) with legs (42), a torso (44), and head (46), and a pair of arms (48). The figure (40) performs generally repetitive movements such as dance-like undulations in a manner that appears to keep time with music. The figure is hollow and connected to a generally constant flow source of air or other gas under pressure (30). The figure is provided with at least two spaced apart generally symmetrically arranged outlets or vents (48b) to allow a discharge of air. In operation, the figure tends to cycle between extending generally upright, and destabilizing or collapsing to a contorted or bent position, and as more air flows in, to extend generally upright. In a preferred form, the outlets (46b, 48b) are generally at the top of the head (46), and at the ends of the arms (48). The dynamic figure (40) movement is a result of the self-contained gas flow, and does not depend upon any external manipulation.

Title: Ieee-1394 serial bus network capable of multicast communication
Inventor: MOMONA MORIHISA
IPC: G06F13/00
Filed: 1999-03-05
Abstract: In a communication network where IEEE-1394 nodes are connected to a serial bus, each node functions as a source or a destination for signaling an asynchronous channel setup request containing a multicast address and signaling an asynchronous channel release request. A multicast manager, connected to the bus, includes a channel allocation table having a number of entries each mapping a channel number to a multicast address. The multicast manager responds to the setup request for making a search through the allocation table, setting a node count value to 1, acquiring ownership of a channel number from an isochronous resource manager and mapping the acquired channel number to the multicast address of the request in a corresponding entry of the allocation table if no channel number was mapped to the multicast address or incrementing the node count value by 1 if a channel number is mapped to the multicast address, and then signaling a reply message. The source node responds to this reply message by multicasting asynchronous stream packets to the serial bus. The multicast manager further responds to the asynchronous channel release request for decrementing the node count value by 1. When the node count value equals zero, the ownership of the channel number is restored to the isochronous resource manager and the corresponding entry of the channel allocation table is cleared.

Abstract: A protective cover for use with a stringed musical instrument (C) comprises a roof-like shaped shield body (11) attachable to the stringed instrument (C) to protect the most sensitive parts and areas including at least the bridge (5) and the strings (2). The shield body (11) has a concave bottom side (b2) and an inner string channel (12) open to the bottom side and designed to accommodate the bridge (5) and the strings (2). The shield body (11) is made of elastically deformable material and has on its slightly arched bottom side (b2) within an intermediate zone thereof locking projections (20, 21) designed to engage instrument recesses (a5) and projections (9, 9'), e.g. the fingerboard end portion from below. At both of its end portions (16', 15') the shield body (11) is equipped with claw-like fixing projections (16.1, 16.2;  15) designed to engage the instrument body (1) at its neckside edge area (a3) and at its opposed edge area (a4) in a mounted position (II), the latter being reached by pressing vertically upon an intermediate portion of the shield body (11) and simultaneously applying longitudinally directed forces, thereby causing a movement of the locking projections (20, 21) and of the fixing projections (16.1, 16.2; 15) into their form-locking positions. Physical loads (shocks, vibrations etc.) are absorbed by the shield body (11), and due to its arched construction, are guided to the robust neck-side edge and lower edge area (a3, a4) of the instrument body (1).

Title: New hev antigenic peptide and methods
Inventor: NG MUN HON
IPC: G01N33/576
Filed: 1999-09-30
Abstract: A highly immunoreactive viral peptide, E2, of the hepatitis E virus (HEV) genome, derived from the carboxyl terminal end region of ORF2, is disclosed. The ORF2 peptide, expressed either as a glutathione S-transferase (GST) fusion peptide (GE2) or as the viral peptide (E2) cleaved from sepharose-bound GE2, proved to be highly reactive with sera from patients having current or past infection with HEV. A special feature of E2 is that it is a conformational antigenic determinant generated by intramolecular interactions between monomers of the peptide to form homodimers. The immunoreactivity is strictly conformational in nature and is only functional when the E2 peptide is in a dimeric form such that immunoreactivity is lost upon dissociation of the dimer. Moreover, diagnostic methods useful in detecting HEV infection and an antigen vaccine composition effective in preventing hepatitis E virus infection in which E2 is utilized are also disclosed.

Abstract: A process for the preparation of a catalyst which is highly active for the synthesis of hydrocarbons from mixtures of hydrogen and carbon monoxide. A silica or silica-containing support is treated with a solution containing both an Iron Group metal, or metals, and nitrous acid, nitric acid, or a nitro-containing organo, or nitro-containing hydrocarbyl compound, or compounds, sufficient to hydroxylate the surface thereof and increase the number of hydroxyl groups on the surface of the support such that the metal component will be highly dispersed, this increasing the activity of the catalyst in a hydrocarbon synthesis reaction as contrasted with that of a catalyst of similar composition, similarly prepared except that the support component of the catalyst was not contacted and simultaneously treated with both the Iron Group metal and the acid.
