Abstract: A new process, particularly simple and economical, for FSH and LH separation and purification starting from crude HMG preferably urinary, comprising the following steps:1) optional exhaustion of crude HMG viral charge in aqueous EtOH2) ion-exchange chromatography on weakly basic anionic resins of DEAE type;3) affinity chromatography on resin having an antraquinone derivative as a ligand;4) optional ion-exchange chromatography on strongly basic anionic resins;Hormones obtained thereby, in particularly pure form and having high specific activity, may subsequently undergo a depyrogenation step.

Abstract: The present invention relates to a bumper device for boats, which is extremely simple to use. The device comprises inflatable bodies, which are associated with the peripheral walls of the boat, and means for inflation-deflation of the inflatable bodies. The means for inflation-deflation can be activated by command, for transition of the inflatable bodies from a condition of rest, in which they are deflated, to a condition of work, in which they are inflated, and project from the peripheral walls of the boat, in order to protect the peripheral walls during mooring manoeuvres.

Abstract: New betaketosulfonic derivatives, the process for their preparation, the photopolymerizable systems containing the same and their application as polymerization photoinitiators for inks, and particularly for inks having high content of pigments are described.

Abstract: The present invention refers to conjugates formed by a natural or modified oligonucleotide, capable of forming a triple helix with a DNA chain, linked to the aglycone moiety of an anthracycline or to an anthracyclinone via an appropriated linker; such conjugates are capable to bind selectively to specific DNA regions inhibiting their transcription and therefore the formation of the corresponding codified protein.

Abstract: A controlled release dosage form for an analgesic that does not contain an expanding polymer and comprising a core containing the analgesic, preferably tramadol or it pharmaceutically acceptable deviates and a semipermeable membrane coating the core.

Abstract: The main purpose of the invention is to enable protective masks commonly known as "large face shield" masks to be used in a variable pressure environment, and in particular under water. The mask (1) internally comprises a pair of parallel protuberances (34) extending below the user's nose and having dimensions such as to be able to hermetically close the user's two nostrils simultaneously when applied to said nostrils by a movement from the bottom upwards. Said movement is allowed by the deformability of the gasket (4) which provides the hermetic seal between the edge (17) of the face shield (2) and the user's face.

Abstract: An automatic ironing machine for ironing the neck and shoulder portion of a cloth article having a bearing framework defining a fixed bottom shaping element, two supporting arms articulated to the framework and a supporting a plate for a top movable shaping element, the supporting plate being rotatively driven, vertically and transversely with respect to the supporting arms.

Abstract: Articles of manufacture are provided with a low surface energy, permanently non-stick, non-fouling and ice-phobic surface by a system of coating comprising applying a primary coating having a surface energy of 22-28 dynes/cm.sup.2 comprising a novel polymeric material having non-stick and hardness properties and then applying a top coating having lower surface energy of from about 18-21 dynes/cm.sup.2 comprising a siliconic polymer and interdigitating means to make the top coating permanent, the means preferably comprising a bi- or polyfunctional organic compound adapted to wet the surface of the primary coating and chemically or physically bond thereto and to couple to the siliconic polymeric substance in the top coating. The coated substrates are resistant to marking by graffiti, to adherence by marine fouling organisms, and frozen ice on the surface is easily removed.

Abstract: A load limiting device to transmit an axial motion to operating mechanisms, comprising: an engaging element (6, 68) which can be connected to a mechanism (4); self-bearing means (2,5) transmitting in axial direction the motion of a driving group (1); a disengagement group (7) which is integral with the element transmitting the axial motion and comprises one or more elastic disengagement means (72) which are connected with the engaging element (68); means (73,74) to adjust the threshold value of the axial load causing said elastic disengagement.

Abstract: Process for the preparation of 2-halomethyl-penems (I) comprising (a) reacting an acetoxy-(protected hydroxyethyl)-2-azetidinone (III) with a 2-halothioacetic acid to form a 3-haloacetylthioazetidinone (V), (b) reacting (V) with oxalyl chloride to give an intermediate (VII), acylated on the beta-lactamic nitrogen, and (c) cyclizing (VII) in the presence of an organic phosphate or phosphonite to produce the corresponding 2-halomethyl-penem (I).
