Title: Modification of hepatitis b core antigen
Inventor: LI JING-LI
IPC: C07K19/00
Filed: 2001-06-22
Abstract: A protein is provided comprising hepatitis B core antigen (HBcAg) wherein one or more of the four arginine repeats has been deleted, said protein comprising the C-terminal cysteine of HBcAg. The deleted region may be replaced by an epitope from a protein other than HBcAg, in which case the HBcAg acts as a carrier to present the epitope to the immune system. The chimeric protein is useful in prophylactic and therapeutic vaccination of a host, for example against hepatitis B virus.

Title: Catalyst and process for aromatic hydrocarbons production from methane
Inventor: WRIGHT HAROLD
IPC: C07C2/52
Filed: 2001-07-27
Abstract: A molybdenum-loaded crystalline aluminosilicate molecular sieve that exhibits the MFI crystal structure and has a silica-to-alumina ratio of about 50:1 is useful for aromatizing a hydrocarbon feed stream. The crystalline aluminosilicate preferably has an external surface acidity selectively passivated by means of an amorphous silica layer. A process for the aromatization of methane comprises a one- or multi-step process that contacts a feed stream comprising at least methane with a catalyst composition comprising the preferred molecular sieve, at hydrocarbon conversion conditions that include a temperature of 600-800 ~C, a pressure of less than 5 atmospheres absolute and a Weight Hourly Space Velocity (WHSV) of 0.1-10 h-1, with the external surface acidity of the crystalline aluminosilicate preferably selectively passivated by an amorphous silica layer. C6-plus aromatic hydrocarbons are preferably recovered from the process by means of an intermediate separation step.

IPC: B65D5/00
Filed: 2003-02-04
Abstract: A container is disclosed having a plurality of interconnected panels forming sidewalls surrounding a central space. Flaps extend from lower sidewall edges and fold along fold lines to form a bottom. Support flanges are arranged along upper sidewall edges on oppositely facing sidewalls. The support flanges are oriented at right angles to the sidewalk and provide a support surface allowing the containers to be stacked one atop another without collapsing or nesting within each other. Each support flange is supported by a truss formed by a panel segment extending angularly from the support flange to a support panel biased against the sidewall to which the support flange is attached by a retaining flap extending from an inner sidewall layer. Locking tabs at the ends of each panel segment are received within recesses positioned in sidewall panels perpendicular to the support flanges.

Title: Discharge lamp lighting device and system using discharge-lamp lighting device
Inventor: KAKIMOTO YASUHIRO
IPC: H05B41/292
Filed: 2002-03-04
Abstract: A discharge-lamp lighting device is provided which decreases arc jumps, suppresses the fluctuation in brightness of the lamp, and prolongs a life of the lamp, by positively accelerating growth of spots even when an inexpensive, small and highly efficient lamp is used. A discharge-lamp controlling portion (101) sets frequencies of drive-controlling signals (A and B) for drive-controlling a commutator (109) within a predetermined frequency range so that spots formed by arc discharge on electrodes composing a high-pressure discharge lamp grow through a cycle of oxidation-reduction of a metal composing the electrodes, and superimposes a triangular wave signal generated on the basis of the drive-controlling signals onto a current-controlling signal (F) over an entire period of the drive-controlling signals so as to make a peak value of the triangular wave constant, thereby adjusting the waveform of current flowing in the high-pressure discharge lamp.

Abstract: A machine and a method for fabricating structural wood components, such as joist building components, is described. The machine comprises a component assembling jig for assembling pre-cut wood pieces at predetermined positions corresponding to a structural wood component design. Magnetic elements are adapted to position connector plates at predetermined locations in the machine. The assembled wood pieces of the jig are displaced to a transfer platform where they are clamped with the wood pieces positioned at interconnecting junctions. The transfer platform then displaces the assembled and held wood pieces to a position adjacent magnetic connector plate applicators whereby the plates are secured to the wood pieces at the interconnecting junctions to interconnect the wood pieces together to form an assembled structural component which is then displaced and discharged from the machine.

Title: Self-authentication of value documents using digital signatures
Inventor: HAYOSH THOMAS D
IPC: H04L29/06
Filed: 2001-11-02
Abstract: An encryption-free technique for enabling the self-authentication of value documents (including personal and commercial checks) presented at a point of purchase or financial institution. Certain data contained on the value document may be signed with a first digital signature and authenticated with a public key certificate issued from a trusted certificate authority. The signed data and public key certificate are stored on the value document, preferably in a two-dimensional bar code data format. In the case of certain personal value documents (such as checks, credit cards, passports, birth certificates, Social Security cards, etc.), a unique personal identification number (PIN) also may be included in the document data that is signed by a second digital signature. At a point of purchase, a merchant or teller can scan and read the data stored in the two-dimensional bar code and other magnetically recorded information, and together with the PIN the customer provides, can authenticate the value document thus presented using the second digital signature. Alternatively, if the customer is not present, if the personal value document contains the second digital signature, the document may be verified using a PIN-generating algorithm or other method that generates all permutations of PINs. The first digital signature alone may be used to authenticate selected data within the personal value document even when the PIN is not available. Similarly, in the case of a commercial value documents, authentication of pre- printed data may be based entirely upon only the first digital signature.

Abstract: A method is described of determining the distance (50, 56) of a projection point (24) of a first imaging beam (22) of imaging device (20) from a measuring point (28) of a measuring device (26) or from a second projection point (36) of a second imaging beam (34) of a second imaging device (32) on the surface (10) of a printing form (12), both the projection point (24) of the first imaging beam (22) and the measuring point (28) of the measuring device (26) or the second projection point (36) being movable in relation to the surface (10) of the printing form (12). In the method, the reflected light intensity of at least a part of a pattern (84), which is produced by the first imaging beam (22) on the printing form (12), is measured as a function of the position of a measuring device (26), so that the distance (50, 56) may be formed as the difference of the position of the measuring device (26) and the correlated position of the imaging beam (22), at which the imaging beam (22) was located when the part of the first pattern (84) was written. The method may advantageously be used in a method of correcting the time triggering of an imaging beam (22), using which a projection point (24) may be produced on a surface (10) of a printing form (12).
