Title: Non-catalytic nitro-naphthalene prepn. - by naphthalene and or mono-nitro-naphthalene nitration in solvent with water removal by azeotropic distn. (BE100576)
IPC: C07C201/00
Filed: 1975-11-12
Abstract: Non-catalytic prepn. of nitro-naphthalenes by nitration of naphthalene and/or mono-nitronaphthalenes with HNO3 in an organic solvent is carried out with removal of water formed in reaction by azeotropic distn. Process is esp. useful for prepn. of 1-mono-nitronaphthalene and of dinitronaphthalenes, esp. 1,5- and 1,8-dinitronaphthalenes. Mono- and dinitronaphthalenes are useful intermediates, e.g. for naphthylamines used in synthesis of dyes. The process allows naphthalene to be nitrated in high yields in presence of a slight excess of HNO3, without catalyst and/or of water-extracting agents; and causes no environmental pollution, by-product being merely dilute HNO3 which can be concd. or re-used.

Title: Blood sample tube uses internal vacuum to cause filling - with blood entering through needle to move piston downwards and maintain filled volume of blood
IPC: G01N33/49
Filed: 1975-12-03
Abstract: A vacuum sealed container is used to obtain blood samples and provide a gas tight stove. The container has a glass body sealed at one end (13) and with an air tight elastic plug at the other (16). The inner section of the plug is retrieved (30) leaving a relatively thin section (22) into which a needle may be inserted. An elastic material piston (24) is located within the tube. After assembly, the container is evacuated to a vacuum of 650 mm Hg. For obtaining a sample, the needle is inserted through the plug and blood begins to enter due to suction. The piston moves downwards at a controlled rate. As the needle is removed the plug reseals to provide an air tight container.

Title: Thermoformed plastics breakers with decorative strip - have square shape with rounded corners and are moulded directly onto strip
IPC: B29C51/16
Filed: 1976-02-24
Abstract: An appts. for holding and pressing a portion of a decorative strip or the like in a thermoforming (deep-drawing) mould for thermoplastics beakers or similar vessels comprises a vertically movable mould for the vessel, open at top and bottom, and a rolling chamber immediately below this mould and integral with it. This entire assembly can be raised and lowered around and relative to a fixed mould base and a transfer piston, both mounted upon a vertical rod projecting upwards from the base of the machine. When the mould and rolling chamber are in their raised position, a strip can be introduced laterally through a slit into the rolling chamber and thus forms a ring ready for transference into the mould and resting with its lower edge on the transfer piston. When the mould and rolling chamber assembly is lowered (position illustrated) this ring of decorative strip is transferred by the piston into the mould chamber. When the assembly is again raised, the decorative strip travels upward with the mould, until the mould walls arrive with their bottom end flush with the mould base ready for the deep-drawing operation. For deep-drawing thermoplastics beakers of the like in a mould in which a decorative strip is already in position, so that this strip becomes integrally bonded to the beaker. The arrangement enables beakers of relatively square or rectangular cross-section, i,e, with sharp radii at the corners, to be fitted with such a stirp. Previous arrangements did not enable this strip to be satisfactorily positioned and drawn into the corners of a generally rectangular mould in this way.
