Title: Quick freeze refrigeration appts. - has circulation fan operable during direct injection of refrigerant
IPC: F25D17/06
Filed: 1975-05-26
Abstract: The refrigeration apparatus has a normal refrigerating system of vaporiser, compresser and condenser and neutral refrigerant agent can be admitted directly to the storage space to bring about rapid initial cooling. A partition divides the storage space from a separated space in which the evaporater is located. A gas circulating fan causes circulation out of the storage space into the bottom of the separated space, up through the separated space and back into the storage space. To protect the drive motor for the circulating fan from low temperature, the motor may have a housing which provides an inslation gap around the motor and is open at its upper side.

Title: Temporary fastening joining two bottles - each with a circumferential groove, is plastic sheet moulded to fit round the bottles and into the grooves
IPC: B65D23/12
Filed: 1975-06-24
Abstract: Neat fastening method for joining bottles that are to be placed on sale together, e. g a scent bottle and an atomiser. It is neat, and simple at unfasten but not so readily undone as to encourage shoplifting. The bottles both have round grooves perhaps somewhere in their length, perhaps formed by the edge of a screw cap. A sheet of transparent plastic, which has two openings, is slipped over the bottles as far as the grooves, which it fits into: the plastic is has the necessary stretch. It is moulded to fit round each bottle for a short distance immediately below the groove; if the groove is under a screw cap, the plastic fits over the shoulders of the bottle and a little way down the slides.
Patent FR-2315308-A1 (FR)
Title: Absorption of vapour on e.g. activated carbon - with regeneration of adsorbent and recovery of adsorbed vapour
IPC: B01D53/04
Filed: 1975-06-27
Abstract: A process for removing gas or vapour from a carrier gas, by absorption on activated carbon, molecular sieves, silica gel or activated alumina in a first adsorber, followed by regeneration of the adsorbent by hot gas and cooling the hot gas and sending it to a second adsorber for recovery of the adsorbed gas or vapour, incorporates distributing the adsorbent in the first adsorber in several layers, passing the carrier gas through one layer only at a speed suitable for adsorption, but passing the hot gas for regeneration through all the layers. The flow rate of the hot gas for regeneration is of the same order as that of the carrier gas, and the whole of the hot gas leaving the first adsorber goes, after cooling, to the second adsorber. The process is partic. useful in removing small quantities of solvents which evaporate into the air in printing works and during many other industrial operations. It allows the gases to flow at the same stages, thus ensuring adequate gas distribution through the adsorbant, but the total flow of gas for desorption is much less, so that the gas giving to the second absorber contains a higher proportion of the vapour and the process is more efficient than existing ones.

Title: Forming hollow non-developable surfaces under fluid pressure - from developable surfaces approximating desired shape welded from sheet
IPC: B21D26/02
Filed: 1975-10-07
Abstract: A non-developable surface is formed from a fabricated approximation of the required shape, by injecting fluid under press. until the required deformation is obtained; heat may be applied at the same time, partic. with thermoplastic materials. Metal may need annealing before and/or after the pressure is applied. A torus of circular section can thus be formed from one of square section: the latter can be fabricated from two coaxial cylindrical sleeves joined top and bottom by circular rings. A sphere can be formed from a surface of revolution whose cross section is an octagon; this surface is composed of a cylinder, two conical frusta and two circular discs. If a sheet of uniform thickness is used, a sphere results when press. is applied; if the circular discs are thicker than the rest, the surface becomes ellipsoidal.

Title: High speed ion plating of substrates - using cleaning by sputtering, and magnetron cathode supplying dense stream of particles
IPC: C23C14/32
Filed: 1975-10-30
Abstract: A thin film is deposited on an electrically-polarised substrate, esp. to obtain a protective coating by ion plating. The substrate surface is cleaned by catholic sputtering until the start of film formation, and then a high density flux of particles is supplied to form the deposited film. The particles are obtd. from a magnetron cathode. Pref. appts. consists of a vacuum chamber contg. a substrate holder; a mobile substrate mask; and a magnetron cathode. Between the substrate mask; and a magnetron cathode is a set of grids, which can be separately earthed, or be at separate potentials which may be positive, negative, continuous, modulated, or at high frequency, in order to separate the two plasmas formed round the cathode and round the substrate. Process can be used, e.G. for depositing carbon, tungsten, carbides or oxides etc.,esp. for providing thin protective coatings on tools. Magnetron cathode provides deposition speeds of ca. 1 mu m/minute which is 20-30 times that obtd. by conventional sputtering; and the magnetron only needs a 600 V supply.
