Patent ES-459408-A1 (ES)
Title: Nasal spray adapter
IPC: A61M11/00
Filed: 1977-06-01
Abstract: The nose adapter is used in conjunction with a manually operated piston pump. It comprises an elongate pipe piece (1) having an inner channel (3) which has a compressible valve shaft (14) of a pump (not shown). At the upper end of the pipe piece (1) there is formed an annular, central pressure chamber (7) delimited by a disc (11). In conjunction with a jacket (12) this disc forms a button which delimits the pressure chamber (7) in the action position shown. A groove (11a) arranged on the underside of the disc (11) extends tangentially to an outlet opening (8), so that the liquid forced into the pressure chamber (7) enters the outlet opening (8) with a slight torque and emerges from this opening in the form of a fine spray mist. The nose adapter can be used as a spray head for a nose spray for the treatment of disorders inside the nose.

Title: Methods and apparatus for determining the stuck point of a conduit in a borehole
IPC: E21B47/09
Filed: 1977-09-21
Abstract: In the representative embodiment of the new and improved apparatus disclosed herein, a so-called "stuck-point indicator" or "freepoint-indicator" tool includes a deformation-responsive sensor tandemly supported between upper and lower hydraulically-operated tool anchors cooperatively arranged to be sequentially engaged with longitudinally-spaced wall portions of a string of well pipe believed to be stuck in a well bore. In the preferred embodiment of the tool, each tool anchor respectively includes a piston actuator which, upon application of a predetermined pressure as developed by a hydraulic-control system on the tool, operates to retract a set of movable anchoring elements and, upon a reduction in that hydraulic pressure, is biased by a spring to extend the anchoring elements. To assure sequential operation of the upper and lower anchors, the hydraulic-control system of the tool further includes a flow restrictor for cooperatively delaying the reduction of the hydraulic pressure acting to retain the lower anchoring elements in their retracted positions until such time that the upper elements are moved into anchoring engagement with the pipe wall.

Title: Process for the preparation of aromatic amines
IPC: C07C253/00
Filed: 1977-11-16
Abstract: A process for the preparation of substituted aromatic amines of the general formula (I) < IMAGE > where R1, R2, R3 and R4 are as defined in claim 1, by direct amination with N-chloramine in a redox-type system is characterised in that an aromatic compound 1-4-disubstituted with an ether group and an acylamino group are reacted with an N-chloramine in an acid reaction medium with a strong acid. Products of this type present considerable difficulties in synthesis by the traditional methods due to the complexity and low selectivity of the processes which lead to the formation of secondary amines and salts. This synthesis technique is instead accompanied by a strong activating effect on the amination and enhanced selectivity. The products thus obtained are of great interest in the field of fine chemicals and particulary in the field of dyes, where they represent basic intermediates for the synthesis thereof.

Patent ES-483789-A1 (ES)
Title: Altering slab width during continuous casting of steel slab - by lowering flexible insert into mould to form temporary mould wall cast into the slab
IPC: B22D11/08
Filed: 1979-08-31
Abstract: During casting via a cooled mould, a steel insert with a compsn. corresp. with the steel being cast is moved from a horizontal position above the mould to a vertical position, so it is partly immersed in the molten steel adjacent to an adjustable narrow wall of the mould. The insert welds onto the solidified skin of the steel in the mould and thus forms a self-supporting wall retaining the semi-solid steel in the mould while the narrow wall is moved outwards to increase the width of the cast slab. Both the oscillation of the mould, and the extn. of the slab out of the mould, can be continued while the mould width is increased. There is no harmful change in the cooling rate of the slab.
Patent ES-485137-A1 (ES)
Title: Stored cryogenic refrigeration
IPC: F25B1/00
Filed: 1979-10-18
Abstract: A holding chamber may be supplied from a storage vessel system with a cryogen, such as liquid CO2, or it may itself be large enough to take the place of a separate storage vessel. The temperature within the holding chamber is reduced to the triple point or below to form a refrigeration reservoir of solid cryogen, as by removing vapor from the chamber to cause evaporation or by employing mechanical refrigeration. The stored cooling power of the reservoir is later employed to meet a large or a periodic refrigeration demand and is thereafter replenished over a number of hours, preferably during a period of non-peak electric demand. This storage principle can be incorporated into a variety of different refrigeration systems. For example, a CO2 storage system may be used to produce and store solid CO2 during a period of low demand upon a coupled mechanical refrigeration system thereafter, the solid CO2 is used to supplement the mechanical system during a high-demand period, thereby increasing the effective refrigeration capacity of the mechanical system.

Title: Device for checking the diameter of a cylindrical hole bored in a thick workpiece.
IPC: G01B5/00
Filed: 1980-10-07
Abstract: Apparatus for testing the diameter of a cylindrical hole machined in a very thick part, comprising a first support having a central cavity in axial continuation of the hole to be tested and a second support mounted rotatably on the first support and having an axial cavity. A shaft bearing a bore-testing means passes axially through the cavities in the supports. A motor driving the support by means of gearing allows the second support to be angularly oriented with respect to the first, and a second drive allows the shaft to be driven in an axial translation movement. Controls for the first and second drives allow a scan to be made successively of the entire length of the hole along two generatrices of a first plane passing through the axis of the hole and along two generatrices of a second plane passing through the axis of the hole. The invention is particularly applicable to bore-testing the holes of a steam generator tube sheet of a pressurized water nuclear reactor.

Title: A method in the manufacture of sulphuric acid from gases generated in discontinuous processes.
IPC: C01B17/76
Filed: 1982-10-25
Abstract: Method of utilizing process gas containing sulphur dioxide obtained from discontinuous processes, in the manufacture of sulphuric acid in a contact plant. When practicing the method according to the invention, all of the process gas, or a predetermined amount thereof, is withdrawn from the process during process operational periods, in which gas containing sulphur dioxide is generated, and the sulphur dioxide contained by the withdrawn gas is at least partially separated therefrom to form a liquid phase containing the amount of sulphur dioxide separated. The gas partially freed from sulphur dioxide, together with any non-withdrawn process gas, is passed to the contact plant for manufacturing sulphuric acid. Stored absorption liquid is utilized during those periods in which no process gases are produced or passed to the contact plant or in which the process gases contain insufficient sulphur dioxide. Sulphur dioxide is stripped from the liquid phase with the aid of a carrier gas, and the carrier gas, together with the stripped sulphur dioxide, is passed to the contact plant. This enables a required amount of gas and sulphur dioxide to be constantly supplied to the contact plant, even during those periods when the discontinuous process does not produce a sulphur-dioxide-containing gas or produce a gas having an insufficiently high sulphur-dioxide amount.
