Title: Oral small pox vaccine - in capsule form
IPC: A61K39/285
Filed: 1972-01-25
Abstract: Vaccine prepn. for oral vaccination against smallpox is produced by (a) grinding freeze-dried vaccinia vaccine in the dry state with surfactant, drying and preservative substances and with dispersant and swellable substances (suitably silicates such as 'Aerosil' (RTM) and Al and Mg silicates), (b) filling into a capsule which is soluble only in the small intestine, and (c) sealing the capsule airtight; advantageously, the capsule is rendered airtight and resistant to gastric juice by coating with a cellulose acetate phthalate lacquer. With the new vaccine, there is no risk of excretion of virulent viruses after vaccination. Stability of the vaccine during storage is improved, and enclosure in a capsule avoids the risk of infection of the mouth and throat after oral administration. Since the capsule only dissolves in the small intestine damage to the vaccine by gastric acid is avoided.

Title: Direct positive image prodn - using diazo photographic products with top PVA layer
IPC: G03F7/09
Filed: 1973-05-23
Abstract: A product for producing a direct positive image by selective exposure followed by simple washing with warm water comprise a support coated with a photosensitive diazo cpd, opt in a binder, and a top layer contg a gas permeable, water soluble hydrophilic polymer pref. PVA modified with 2,4-disulphobenzacetal. Upon exposure the diazo cpd decompses to forms N2 which is trapped by the top layer. When washed the top layer swells and frees the N2; this causes rapid rupture of the top layer in the exposed areas and results in the complete elimination of those areas by washing with water. The unexposed zones remain intact to give a positive image.

Title: Measuring pollutant concn. in a gas, esp. atmospheric water vapour - by photodissociation and photometry of products
Inventor: BERTAUX JEAN LOUP
IPC: G01N21/63
Filed: 1975-10-24
Abstract: To measure the concn. of a body contained in a gas, such as water vapour in the atmos., the gas is first irradiated with a radiation having a sufficient wave length to photodissociate the body to be measured. At least one of the prods. of photodissociation is then photometered to determine its concn. which is proportional to the concn. of the body to be measured. Pref. the wave length used is sufficient to produce one of the products of photodissociation in an excited state; the photometry consisting in the measurement of the intensity of the light emitted when the product relaxes to the ground state. When the product is not produced in the excited state, the measurement may be by absorption photometry. System makes it possible to measure accurately the concn. in a gas of a body which does not have an absorption spectrum easily distinguished from other absorption spectra.
