The hinge has a body with a cylindrical body, in which a pin is rotatably arranged. The method involves the seat for the pin being mechanically tooled and attached to the hinge element by pressure-welding. The cylindrical body is fixed to the apex of a rib on the hinge body which is formed through plastic deformation. The rib stands above the datum level of the hinge element by a distance (H) whi...

In order to facilitate the temporary storage of glass panes 19 during two consecutive processing steps, the storage 1, 1A comprises a framework 2 able to move on wheels 6 formed by at least one pair of parallel and inclined vertical uprights 7, on which can move perpendicularly, guided by transport chains 11, pairs of support rods 18 matched up and supporting said glass panes 19. The mechanism 4 f...

In order to reduce the overall size as much as possible, the clamp (1) has the jaw operating arms (6) substantially perpendicular to the jaws (4) and said jaw operating arms (6) defining a space (21) within which both the elastic means (9) and the operating arms (8) for elastic means are housed.

In order to operate both arms (21, 22) of the clamp (15) with the same force and at the same time, the guide carrier element (23), which comprises two longitudinal surfaces (26, 36) on which the free ends of the movable jaws (41, 42) slide, is formed in one piece and can move vertically transverse to said free end so as to be instantaneously and automatically self-centering about them and hence ab...

The use of food dyes as chemical detectors for caries which once chemically bound to the caries cannot be removed except with mechanical instruments.

Rolling slurry is produced from rolling steel as iron oxide particles moistened with a mixt. of water and lubricating oil, and obtd. by sedimenting or filtering cooling water from steel rolling plants to modify the colour of brick prods., esp. wall bricks and roofing tiles. Colour-modified brick products produced from crude clay are also claimed, in which 5-50 (pref. 5-20) % the above rolling slur...

A surgical incision member is provided including a body portion defining first and second longitudinal ends, tissue penetrating portion adjacent each longitudinal end of the body portion, suture attachment structure intermediate the tissue penetrating portions, and a suture attached to the suture intermediate structure. A method is also provided wherein the suture is attached to the surgical incis...

An electrical capacitor includes an organic electrolyte to provide high power, high energy density, and a broad operating temperature range. The capacitor includes electrodes and an electrolyte system comprising a salt combined with a solvent containing a nitrile. The electrolyte system is selected to be relatively nonreactive and difficult to oxidize or reduce so as to produce a high electric pot...
