Abstract: In a first embodiment, the present invention is directed to a container body for a circular or non-circular container with an attached lid covering the upper opening, the container body comprising a bottom and a side wall surrounding the bottom, the side wall extending essentially rectangular in respect to the general plane of the bottom or extending with an angle therewith which does not exceed about 95°, wherein in at least two first areas of the said side wall, a first shoulder is formed, the first shoulder being arranged at between ? and ? of the height of the side wall, wherein in at least part of said first areas, first flutes are arranged at least below the said first shoulder, the flutes running essentially vertically from the bottom side end of the side wall up to the lower end of the said first shoulder, wherein in case the container is a non-circular container, the first areas are areas which, seen in plan view from above, are most strongly curved, compared to second areas, and are situated between

Abstract: The projector for medical use comprises an illuminating cupola articulately mounted about different axes and provided along its wider outline with a protecting flange of flexible material dimensioned so as to constitute a device for gripping and operating the cupola and defining an inner chamber bounded, on the outer face of the flange by a sufficiently thin wall to be deformed by manual pressure and allowing the operation of control mechanisms of a device for unblocking and reblocking articulation brakes of arm supports of the capola.

Abstract: The unit may be a surgical operating table and has electric control devices. The unit comprises two identical electrically-operated jacks 14, 15 which are located at equal distances from a vertical plane containing an axis about which the platform 11 of the unit is pivotable in a transverse plane, the jacks exerting on a universal joint 8 connected to the platform forces of the same magnitude and in the same direction or in opposite directions, and a third electrically-operated jack and a pneumatic spring device disposed on opposite sides of that vertical plane.

Abstract: An illuminating device which employs prisms to concentrate light onto an operating area or field.The prisms are formed by an assembly of straight prism-segments which are combined into radial sectors the angular extent of which is such that the beams issuing from the source are reflected onto the field to form an area of approximately the same width as the field. Each sector thus illuminates the whole of the field, resulting in a great uniformity of illumination.Applicable to the illumination of operating tables and in general to the illumination of cavities and their walls.
