Abstract: Portable gas delivery equipment comprising a gas bottle (1) having a height of less than 50 cm, a gas tap or tap/pressure-regulator (2) mounted on the bottle (1), mechanical protection means (3) placed around the bottle (1) and around the said gas tap or tap/pressure-regulator (2), characterized in that the said protection means (3) comprise at least one external rigid shell (3) formed from at least two sub-parts (3a, 3b, 5) that include catching means (10, 11) for firmly fastening the said sub-parts (3a, 3b, 5) together. One or more additional protective elements (14a, 14b) are provided between the half-shells (3a, 3b) and the tap or tap/pressure-regulator (2) in order to improve the protection of the tap (2). Furthermore, the external rigid shell (3) has an external profile with a neck (12) designed in such a way that it allows the equipment to be manually gripped by a user via this neck (12).

Abstract: Portable gas delivery system intended for medical use. The gas delivery system has a gas cylinder with a bottle body and a gas flow controlling device. The gas cylinder body is partially covered by a first protective casing and the gas flow controlling device and/or the first protective covering are Partially covered with a second protective casing. A protective cowling also provides protection. Such protective casings may be joined together and have a disk shaped bottom portion to protect the bottom of the gas cylinder.

Abstract: The invention concerns a gas bottle in particular for medical use, comprising a generally cylindrical bottle body (1) comprising members (3) regulating gas output and optionally a protective covering (2) arranged around the members (3) regulating gas output. The invention is characterised in that the bottle body (1) is at least partly covered with at least a first protective casing (11), and the members (3) and/or the protective covering (2) are at least partly covered with at least a second protective casing (21). The invention also concerns a protective packaging for a gas bottle formed with a first protective casing (11) portion and a second protective casing (21) portion mutually integral and/or formed in a single piece, the first casing portion (11) comprising a disc-shaped base (12) to protect the base of the gas bottle.

Abstract: A process for manufacturing glass objects such as bottles, in which a cold fluid containing a cryogen is sprayed around and/or under the bottles in the region of the transfer tongs and/or of the standby table in order to accelerate the cooling of the bottles and improve the quality of the latter and the productivity of the manufacturing machines. This cooling may be accompanied by a localized, or complete quenching of the bottle.

Abstract: According to the invention, ventilating air blown around and/or in the walls of a mould is cooled so as to maintain substantially constant, at least during predetermined periods of time, the temperature of the air around and/or in the walls of the mould, irrespective of the ambient temperature.

Abstract: Process for lubricating a surface for the manufacture of a glass object, in which a layer of lubricant is periodically deposited on the surface.This layer of lubricant is produced with the aid of a source of heat such as an oxyfuel flame having a temperature higher than 2000.degree. K. through which there is injected during a given period of time a gaseous hydrocarbon or a mixture of gaseous hydrocarbons comprising at least 15% of a constituent in respect of which the ratio fo the number oc carbon atoms to the number of hydrogen atoms C/H is higher than 0.75. The rate of injection of the hydrocarbon through the flame and the temperature of the latter are controlled in such manner as to obtain a porous layer of carbonaceous particles capable of burning in the air when they are deposited on the glass object when the latter is still hot.
