Abstract: A gate for ski sports indicates and traces the path to be followed by a skier on a ski slope and has two poles to be driven into the snow pack and a panel joining the poles at their upper portions. An indicator associated with the poles indicates a predetermined height of the panel relative to the snow pack thereby allowing correct height-positioning of the panel. The indicator may be a white or colored band, text, a band combined with text, or other forms and be at various locations to indicate the predetermined height of the top and bottom edges or both edges of the panel. This facilitates easy and correct height-positioning of the panel particularly according to applicable regulations and standards, to thereby considerably reduce the risk of dangerous and disastrous collisions of the skier against the gate.

Abstract: A flexible slalom ski course pole has a fixed base to be driven into the snow and a flexible post extending above the snow. The base and post are connected by an intermediate hinge located a short distance above the snow so the post can bend relative the base and later move back into its initial vertical position, when impacted by a skier during a race. The hinge is associated with a protective sleeve which is provided in addition to or as a part of the hinge, and is disposed around the post adjacent the snow. The sleeve and post have first and second colors which are distinct so their contrast allows the skier to easily recognize the pole and the point it is inserted in the snow, and the gate judges to accurately appreciate proper passage of the skier around the pole.

Abstract: A single pacemaker catheter electrode for the biventricular cardiac electrostimulation by an assisted cardiac stimulation device by the insertion of its stimulation tip into the right ventricle of the heart without the need of using a second catheter electrode directed to stimulate the left ventricle, including a stimulation screw having a penetration tip brought to the distal end of the catheter electrode which is such as to allow the electrostimuiation screw to be driven from the outside in order to deeply penetrate into the ventricular septum separating the two ventricles.

Abstract: Safety element intended to assure in time the electric reliability of pulse transmitting leads, comprised in apparatus for the electric stimulation of the heart (pacemaker) and consisting of a main metallic coil of tubular structure delimiting an inner bore, covered by an insulating sheath, which safety element comprises a flexible lead formed by one or more wires coiled in tight turns or intertwined and provided with a rounded head for making it easier the introduction of the safety element in the bore of the main metal coil of the pulse transmitting lead.

Abstract: Improvement in pacemakers for a quick and safe replacement thereof without interrupting the electric stimulation of the patient's heart from the outside, wherein the contact pin of the electro-de-catheter inserted in the pacemaker is accessible from the outside, and related tool to be utilized therewith by which tool the contact pin can be pushed out of the pacemaker; the tool is provided with contact means to the electrode catheter which means make it possible the uninterrupted electric stimulation of the heart during the whole replacement operation of the pacemaker.

Abstract: Equipment with an incorporated cardiac radio-frequency receiver (CPR) for temporary heart stimulation from the outside in case of open-heart operation, suitable to be left insitu to provide permanent stimulation if subsequently necessary. The equipment is formed of an electrode with epi-cardial stimulation tip, and a quick jack-type connection emerging from said cardiac radio-frequency receiver and suitable to rapidly and easily connect a permanent pacemaker.

Abstract: Apparatus for loading and unloading palletized materials (C) into and from isothermal delivery wagons (F). The apparatus comprises a powered carriage (4) which is longitudinally movable on parallel guides (1,1') secured to the upper interior portion of the wagon (F). A telescopic guiding and lifting/lowering structure connected to the underside of a powered and transversely movable slide (17) and supporting in cantilever fashion a fork (28) for handling the palletized loads (C), comprises at least one jack (26, 26',29) of the multiple-stage single or double-acting type, and preferably of the hydraulic type. The fork (28) is rotated about a vertical axis in order to angularly position it with respect to the load to be handled, and is then locked in such position.

Abstract: The armoured guard-house allows one or more guards to be protected and is provided with an armoured lateral envelope provided with at least one glazed observation area or window protected by bullet-proof glass, a base and an upper closure canopy. The window is composed of an opaque reinforced frame of grid supports delimiting a plurality of window openings of relatively small dimensions, closed by means of transparent panes made of a bullet-proof glass and each having a reflective surface facing outwardly of the guard-house in such a way that an external observer cannot see through the glazed area. The guard-house is made in such a way as to resist the impact of armoured bullets fired from military rifles of the FAL-type.
