Title: Prestressed concrete prodn. without requiring autoclave conditions - using Portland cement, insoluble anhydrite and dispersing agent
IPC: C04B/
Filed: 1977-08-12
Granted: 1985-05-21
Abstract: Concrete of high strength is prepd. from a mixt. contg. 400-600 kg. of Portland cement/m3 concrete. The mixt. also contains 3-30 wt.% of insoluble anhydrate (type II) and 0.1-3.0 wt.% of a cement dispersion agent, both based on the wt. of Portland cement. Concrete moulded parts are obtd. by mixing the above ingredients, opt. contg. Al2 (SO4)3. 16-17 H2O, a cement expansion agent and a powdery pozzolano material, and adding water to a water:cement proportion of 25-35 wt.%. 38-48 wt.% of a fine aggregate is added. After moulding the concrete is subjected to a presteam treatment, followed by a steam hardening at atmospheric pressure. High strength concrete is obtd., suitable for posts, pillars, etc., relatively quickly without requiring autoclave conditions. It has a high prestress with reduced relaxation. The concrete has no tendency to crack after hardening. In an example, a concrete contained a condensation product of beta-naphthalenesulphonic acid and formaldehyde (dispersing agetn).

Title: Free radical polymerisation of vinyl chloride - in suspension or dispersion in presence of small amt. of alpha olefin
IPC: C08F/
Filed: 1975-05-15
Granted: 1979-11-20
Abstract: Free radical poymsn. of vinyl chloride in suspension or homogenised dispersion is carried out in the presence of 0.02-0.08 wt. % of at least one 6-20C alpha-olefin calculated on wt. of vinyl chloride, which is added (a) before the start if a homogenised dispersion polymsn, or (b) before the start or during a suspension polymsn. but in any case before the beginning of auto-acceleration of the reaction. The tendency for auto-acceleration of the polymsn which can lead to uncontrollable conditions is avoided. In view of the claims of GB 1220714 that at least 0.1 wt. % of a 10-22C alpha-olefin is needed for this purpose, the efficiency of 0.02-0.08 wt. % is unexpected.

Title: Expansible build up drum for tyres and tyre breaker belts - has movable central segments, cylindrical springs in an elastic envelope
Inventor: AVENIR ANANIEVICH ECHIN
IPC: B60C/
Filed: 1975-08-07
Granted: 1979-12-20
Abstract: Drum comprises central segments fastened on levers which are displaced by an opening mechanism; cylindrical springs fastened at the segments, and an elastic envelope covering the springs. The springs are shaped as a bellows whose elements are distributed over the width of the bearing surface of the segments of the drum, and have lateral sections whose shape corresponds with the profile of the type to be built up. The elements of the spring embrace the expansible segments and are, in addn., bearing on elastic stringers whose one end is connected with a given segment whilst the other end slides freely over the adjacent segment as the drum is being expanded. Drum construction prevents deformation of the tyre to be built-up.

Patent IT-1045381-B (IT)
IPC: G01R31/28
Filed: 1973-08-31
Granted: 1980-05-10
Abstract: Propagation delay testing is performed on a generalized and modular logic system that is utilized as an arithmetic/logical unit in a digital computer. Each arithmetic/logical unit of a computer is formed of arrangements of combinational logic networks and storage circuitry. The storage circuitry has the capability for performing scan-in/scan-out operations independently of the system input/output and controls. Using this scan capability, the method of the invention provides for the state of the storage circuitry to be preconditioned and independent of its prior history. Selected propagation paths through the system circuitry are sensitized by test patterns from an automatic test generator. By altering selected inputs and cycling controls applied to the networks of combinational logic and their respective associated storage circuitry, propagation delay indications through the selected paths are obtained to determine the status of these path delays through the logic system.

Title: Redox sintering of metal powder - for metallizing a non-metallic substrate
IPC: B22F/
Filed: 1974-10-28
Granted: 1978-08-10
Abstract: The redox sintering of metal powder comprises shaping a quantity of powder metal particles to form a body, heating this body in a furnace at a temp. which is lower than the standard sintering temp. of the metal, changing the atmosphere inside the furnace repeatedly from oxidising to reducing nature and maintaining the temp. so that the surface of the metal particles is alternately oxidised and reduced and in which the metal is attacked in such a way that, at the furnace temp., a surface oxidation and -reduction occurs. A non-metallic substrate covered with a quantity of powder metal particles is metallized by this sintering procedure. Method is used for the metallisation of ceramic substrates for soldering purposes.

Title: Plastics containers with composite walls - comprising a low permeability layer backed by a scavenger filled layer
IPC: B65D/
Filed: 1977-09-01
Granted: 1985-06-18
Abstract: Plastic containers are moulded with composite walls including one layer which is a low permeability barrier for some gaseous species, e.g. O2, and a complementary layer incorporating dispersion of a chemical scavenger for the same species. Used for preventing entry or escape of the gaseous material relative to the inside of the container. The barrier layer is located nearest the face exposed to the gaseous concn. the scavenger filled layer being positioned to trap any of the species which permeates the barrier. For protecting oxidisable foods or preventing taint transfer, the composite wall structure reduces the apparent permeability of plastic walled containers by comparison with e.g. glass or metal containers.

Title: Toy knitting machine - with crank wheel actuating reciprocating and turning needle and plastic frame feed mechanism
IPC: A63H/
Filed: 1976-12-22
Granted: 1985-04-17
Abstract: A toy knitting machine to knit yarn in loops around a continuous plastic grid frame consists of a crank handle, a feed mechanism for the frame and a needle which moves up and down and has a hook at the end. By coordinating a reciprocating movement with a twisting movement the yarn can be fixed in loops to the frame. The rotation of a crank on a wheel of the drive shaft turns a contrate wheel and through a gear wheel the disc which has a radial slot. A crosspiece with a pin which engages in this slot has a toothed rack in engagement with a gear wheel. This turns the needle with the hook at a certain point of its up and down stroke. All movements are derived from a simple turning of a crank handle.

Title: Procedure for creating arches in tunnels by means of reticulated archways equipped with mutable joints
Inventor: FRANCO PIERLUCIANO
IPC: E21D/
Filed: 1989-05-15
Granted: 1992-06-23
Abstract: As noted, in the construction of tunnels, the archway (where necessary) is an essential element of the excavation, as they protect those employed in these operations and the excavation machines from sudden falling rock material from the excavated surface. According to the preceding technique, normally the archway is constituted by a curvilinear profile in iron, placed at appropriate intervals, and by a spray covering of quick-drying cement. The solution proposed here regards an archway with iron support in a studied reticular structure with important resistance characteristics and of primary mutability. Provided said structure is realized with iron of resistance nearly double with respect to the profiles, it is possible to achieve an important savings, bearing in mind the increased construction cost, in the adoption of this type of archway.
