Title: Artichoke treating machine
IPC: A23N15/00
Filed: 1974-01-11
Abstract: The invention provides a machine which extracts artichokes one-by-one from a hopper, and conveys them individually on a conveyor device including grooved rollers, which rollers align the artichokes so that their axes are horizontal. Artichokes with their stems pointing in the wrong direction are manually or automatically reversed. Pincer arms remove the artichokes one-by-one from the conveyor at the end of its travel, and convey them to clamps on a wheel, where cutters are employed to trim the artichokes, whereafter they are released by the clamps to drop into a hopper. Both the conveyor and wheel movements are intermittent and synchronised.

Title: Winches for hauling on board purse nets or similar fishing devices
IPC: B63B35/20
Filed: 1975-04-23
Abstract: Winches for hauling on board fishing vessels purse nets or similar fishing devices. The nets are pulled by frictional engagement with at least two rollers rotatable in mutually opposite directions and arranged in spaced apart relationship to project freely outwards from a common pivotable end member for adjusting the rollers in various oblique positions relative to a vertical plane. The rollers each have inner and outer rest portions with friction-promoting means, such as rubber coating, the inner rest portion having a smaller diameter than the outer rest portion thereby enabling a float-supporting side of the net to bear against the roller between the inner and outer rest portions in a manner regulated by the oblique positioning of the rollers. Furthermore, each roller has an annular portion formed without friction-promoting means to constitute a net-slide portion. By arranging the net-slide portion between the two rest portions, the float-supporting side of the net can be readily controlled by relatively slow pivoting of the rollers in the one or the other direction from the outer rest portion to the slide portion and from the inner rest portion to the slide portion.

Patent ES-444595-A1 (ES)
Title: Apparatus for impregnating porous materials with fluids
IPC: B27K3/02
Filed: 1976-01-24
Abstract: It permits the impregnation according to the double-vacuum, the vacuum-pressure and the Lowry processes, in particular for the protective treatment of solid wood and wooden materials with liquids for protection against biological and atmospheric damage. In known apparatus of this type, the time required for filling and emptying the impregnation cylinder is quite considerable, so that, apart from the variation in absorption due to the material, further variation in absorption results from the impregnating process itself. In the apparatus according to the invention, the cross-section of the connecting line (d) between the impregnation vessel (JG) and the supply vessel (VG) arranged above it is dimensioned in such a way that a period of only 6 minutes, preferably 4 minutes, is sufficient to completely fill the impregnation vessel. The same pipe dimensioning and therefore also the same times apply to the emptying of the impregnation vessel, for which a collecting vessel (AG) is arranged below the same, so that during both the filling and emptying of the impregnation vessel the free fall of the liquid can be utilised and thus work can be carried out in an energy-saving manner.

Title: Process for the preparation of di(amino phenyl)methanes
IPC: C07C209/78
Filed: 1976-06-08
Abstract: Aniline and formaldehyde are condensed (2-10 moles aniline per mole of formaldehyde) at ambient temperature in the absence of acid catalysts to give a mixture of aminals (anilinoacetals) and aniline from which the water is removed. The anhydrous aminals are contacted with a solid catalyst (clays, zeolites, diatomaceous earth) using either batch or continuous operation initially at 20 DEG C to 55 DEG C until benzylamine formation is substantially complete, then at 50 DEG C to 65 DEG C until benzylamine conversion to methylene polyphenyl polyamines is 75 - 90% complete and finally at 80 DEG C to 100 DEG C. A polyamine mixture is obtained in which diaminodiphenylmethane is the major (order of 90 percent by weight or higher) component, the bulk of the higher oligomeric polyamines being triamine. The diaminodiphenylmethane component contains of the order of 85 percent of 4,4'-isomer, the rest being 2,4'-isomer except for very small amounts (order of 2 percent or less) of 2,2'-isomer.

Patent ES-474407-A1 (ES)
Title: Identifier for manual switchboards with conference facility
IPC: H04M15/00
Filed: 1978-10-20
Abstract: A line identifier at a telecommunication switchboard comprises a matrix of magnetic-induction elements serving as current sensors for detecting a request for establishing a connection between a selected incoming line and a selected outgoing line. The sensors are connected to a multiplexer for providing samples in a time-division mode to a logic circuit controlled by a pair of microprogrammers and addressing a read/write memory for storing information on the states of the sensors. The logic network, upon receiving from a sensor an identification request for a selected outgoing line, such request implicitly coding a selected input line, activates a relay which closes a circuit enabling the energization of a sensor whose output signal to the logic network identifies the outgoing line selected via the switchboard for connection to the prior-identified incoming line. Upon successful identification of a selected incoming line and at least one selected outgoing line, the logic network emits energization signals to a pair of relays which thereupon break the circuits energizing the sensors and establish a link between the selected incoming line and the selected outgoing line. The logic network is connected via its control microprocessors to a computer for communicating thereto the identities of interconnected lines. The logic network with its associated multiplexer and microprocessors may be duplicated for cross-checking operations.
