Title: Method of producing additives for cementitious composites and additives produced in this way
Inventor: PENNA ANNA MARIA
IPC: B28B/
Filed: 1990-09-26
Granted: 1994-06-10
Abstract: Additives for cementitious composites formed from pieces 1A,3 of carbon fibre preferably blocks 1A or filamentary bodies 3, bonded together by dressing them with bonding resins and having an adhesive capacity with the cementitious matrix. The cementitious composites are cement, inert fillers, fluidizers and/or superfluidizers, expansive additives, artificial and/or natural pozzuolanas, and synthetic polymers. The method of producing the said additives involves: dressing the carbon fibres by immersing them in an aqueous dispersion of resins taken from the following group: acrylic, styrene-acrylic, styrene-butadiene, and vinyl; followed by drying and optional chopping to obtain the blocks of fibres 1A or the filamentary bodies 3 having the desired measurements. <IMAGE>

Title: Pneumatic rubber fender of cord reinforced fabric layers - is assembled folded on drum and turned inside out
Filed: 1975-12-22
Granted: 1981-11-30
Abstract: A pneumatic fender of laminated, cord reinforced, rubberised sheet material with a cylindrical contour and roughly spherical ends in one of which there is an air valve, is produced on a rotary former. The main body of an unvulcanised rubber fender is built up as a cylinder on an assembly drum with a closed end face, against which a flat piece of the rubberised material is held and bonded to the edge of the cylindrical layers. The open end of the cylindrical body id folded back towards the first end cover and a number of second end covers are held in posn. and bonded to the various cylindrical layers in their peripheral zones, so that an actual unvulcanised fender with one half folded inside the other is formed on the drum. There is a valve in the second end cover and when compressed air is blown in, the reversal of the cylinder forces the fender off the drum, and it is vulcanised whilst inflated. Eliminates the complicated operations necessary when paper formers are used and have to be removed after vulcanising.

Patent IT-1004381-B (IT)
IPC: H03K3/013
Filed: 1974-03-15
Granted: 1976-07-10
Abstract: A bistable logic circuit generating a stable, preferred output logic state for activating a circuit load having a known response time and capable of being tested while installed and in service without activating the output load includes preferential output state logic memory means, asymmetric delay means and first logic means to generate an output which is the logic product of the memory output and the negation of the circuit Reset input. Second logic means generates the memory means control signal as the logic sum of the circuit Set input and the circuit output asymmetrically delayed by a time period less than the load response time. A test pulse output having a time duration less than the load response time is generated for a set input having a time duration less than one internally determined time period whereby the circuit load is not activated. A load activating output is generated at any time, including the test time period, for a Set input having a time duration greater then another internally determined time period and maintained until a Reset input is solely present.

Title: An irreversible winch device for curtains
IPC: A47H/
Filed: 1990-01-12
Granted: 1993-11-05
Abstract: A winch device to irreversibly move curtains and the like, this irreversible movement is obtained by inserting two pairs of spheres (33), held apart by the appropriate elastic means (35), in the correct rolling trail (31) of various sizes, carved out of the inside of the device (1) thanks to two arching overhangs (27), carved on the hub (15) and having a slight curvature that follows the curvature of the internal surface (23) of the inside wall (21) concentric to the enclosure (1). The device works on a tooth wheel (5) crown gear (11).The element (11) on which the tooth wheel is carved (13) brings, on the opposite side of the vertex, two T-shaped overhangs (37) that can be inserted with the stem (39) between the end of the bowed sector (27) and almost comes in contact with the T-wings (41) and with the above-mentioned spheres (33). In the rest position, the device is blocked so that the spheres (33), pushed by the respective clamps (35) press against the lesser rolling trial light (31) that will be less wide than the spheres; as soon as the users turn on the crown element (11) with the starter gear (5) the T elements (37) of the said element will press against the two spheres (33), opposite to the vertex, and push them towards the centre of the trail (31) which is wider than the spheres (33) and is a zone where the spheres can roll. With this given push to the two spheres opposite to the centre of the T element (37), the device frees itself from the rotation; with a similar given push to the other two spheres, opposite to the centre and with respect to the abovementioned two T elements (37), the device frees itself in the other rotation directions. To detect that, given the decisive innovative concept of the irreversible mechanism, the device in question has a high mechanical return, dealing with a tooth wheel-crown tooth pair that operates the rolling elements (spheres) in the opposite rolling trails.

Title: Insulating panels made of foam resin to be put on the roof frame under the roof's covering
Inventor: FERRARI LUIGI
IPC: E04B/
Filed: 1989-01-04
Granted: 1992-09-21
Abstract: The insulating panel made of polystyrene foam, to be modularly put on the roof frame to form a continuous insulating covering is furnished with a longitudinal seating embedded into the upper face directly over and parallel to the grooving. This is normally present on the lower surface of the panel to receive the listel of the frame. After a group of panels have been hung, a wooden listel with a length equal to the layers width is stuck into the longitudinal seating of the panels still sticking out of the upper level of the panels. This a sufficient height to constitute the hooking edge of the tile or of the roof tile covering. The stuck listels increase the resistance to the impact and the snowy load substituting itself for the foam rubber corners, covered or not, of the panels that are easily ruined with concentrated loads. The listels effectively distribute the load maintaining the integrity of the foam resin panel and contribute to the robustness of the entire covering.
