Title: Purification of pivalolactone
IPC: C07D315/00
Filed: 1968-07-08
Abstract: Pivalolactone is purified by intimately mixing the lactone at a temperature of from 5 to 95 DEG C. with an aqueous alkaline medium having a pH of 8 to 13.0, subjecting the mixture to phase separation, removing the aqueous phase and subsequently intimately mixing the lactone with demineralized water followed by phase separation and removal of the aqueous phase. The alkaline medium is preferably a solution of one or more oxides, hydroxides or carbonates of alkali and/or earth alkaline metals, ammonium compounds or bicarbonates of alkali metals. The demineralized water has a pH of between 3.5 and 8.5 and comprises not more than 8 x 10-30% by weight of alkali or earth alkali metal compounds. The use of water immiscible solvents such as aliphatic or halogenated aliphatic or aromatic hydrocarbons or aliphatic or halogenated aliphatic ethers is advantageous. The purified product can be further purified by distillation and stabilized by the addition of di- or tri-nitrophenols or the addition products of boron trihalides and Lewis bases.

Patent ES-369019-A1 (ES)
Title: Apparatus for aligning continuous casting mold with the casting metal supply vessel
IPC: B22D11/053
Filed: 1969-07-01
Abstract: In case of oscillating chills, mechanical disturbances in operation of the installation frequently occur because the chill sticks to the nozzle or when a large one-sided deposit between the nozzle and the interior wall of the chill is formed, which affects the life of this part. This shows that these mechanical disturbances can be basically associated with the nozzle slightly changing its position and/or its direction in the course of the casting process. This position or direction change of the nozzle is connected with the thermal effects, those to which the wall of the casting container supporting the nozzle is exposed. The changes of the position between the surface of the nozzle and the wall of the chill resulting from the changes of the position, or direction, of the nozzle can also lead to molten metal entering the slot between the corresponding opposed surfaces of the chill and of the nozzle, which occasionally leads to blocking of the chill when this metal solidifies in the slot.

Patent ES-450618-A1 (ES)
Title: Screening apparatus
IPC: B07B1/20
Filed: 1976-08-11
Abstract: In a screening machine of the type having a perforated cylinder through which the material being screened is passed and a rotor for maintaining the cylinder perforations open, failure of the cylinder due to torsional forces imposed on it by rotation of the rotor is prevented by providing several beam-like cantilevers which extend longitudinally of the cylinder and resist the twisting, torsional forces imposed on the cylinder during screening operations. Intermediate reenforcing rings, which are designed to withstand radially directed loads imposed on the cylinder, are restrained against movement longitudinally of the cylinder by means of clips which are welded to the cantilevers on opposite sides of each of the rings. The cantilevers, therefore, also serve as an area on the cylinder to which the clips can be welded, eliminating the necessity of making welds at undesirable locations near perforated portions of the cylinder. The number of foils carried by the rotor and the number of cantilevers are selected such that there is an odd number of one and an even number of the other to avoid having all cantilevers receive a radial load simultaneously as would occur if the foils passed simultaneously all of the cantilevers.

Patent ES-473656-A1 (ES)
Title: Orifice trim and backpressure plate for high pressure valves
IPC: F16K47/08
Filed: 1978-09-26
Abstract: A new and improved fluid restrictor means for use in a valve structure, as a backpressure plate, or the like and generally comprising a plurality of close-fitting mating cylindrical parts each of said parts including a plurality of openings spaced across the surface thereof. The mating parts are rigid in construction and arranged and configured whereby they are in a contacting relationship and the openings of contiguous mating parts are in an overlapping relation to form restricting orifices for flow communication between complementary openings. The volume of each of the openings is sufficient to form an expansion chamber for high pressure fluid flowing thrugh the restrictor means. The disclosed fluid restrictor means provides a structure which is easily arranged according to precise engineering specifications for a particular application. For example, all of the dimensions for the expansion chambers and restricting orifices are determined by the size of the openings in the mating parts, the thickness of the parts and the relative positions of the mating parts when in the final assembled form. These factors are determinable with great mathematical exactness and the present invention permits a highly precise implementation of the predetermined flow path characteristics into the structure of the disclosed fluid flow restrictor means.

Title: Security wallet for transmission of valuable documents - has adhesive bonded flap opened only by tearing envelope material
IPC: B65D33/18
Filed: 1979-09-26
Abstract: A sheet of synthetic film is folded and welded along its lengthways running edges, to leave a flat which can be turned over the opening to seal the interior of the wallet thus formed. A layer of adhesive is applied at least along the flap, by means of a protective ribbon which can be easily pulled off. The bond when the flap is glued down is such that the wallet cannot be opened without tearing away the material of which it is made. This may be made more certain by the provision of a weakened line such as a row of perforations. The wallet is intended for the carrying of valuable documents by third parties under conditions ensuring that if the wallet has been tampered with during transit, this is immediately obvious to the receiver.
