Patent IT-1068166-B (IT)
IPC: F28F9/02
Filed: 1976-09-30
Granted: 1985-03-21
Abstract: The heat exchanger has two header boxes provided for the inflow and outflow of a fluid. Three walls of each header box consist of an extruded U-section. The wall thicknesses of the U-section are of different sizes and are designed such that it is possible to achieve a maximum capacity for static loading by internal pressure in conjunction with a minimum outlay on material. By contrast with header boxes made from bent sheet metal, this design has the advantage that it can be produced from material of higher strength, and that the outer walls can be constructed flat over a larger area, which permits larger tube connecting pieces. <IMAGE>

Title: Monolithic metering signal generator for telephone
Inventor: SILIGONI MARCO
IPC: H04M/
Filed: 1984-06-06
Granted: 1989-12-14
Abstract: The monolithic integrated telephone circuit forms part of the exchange equipment and has a call charge signal regulator. The signal is formed by an a.c. voltage generator (TTX), of constant amplitude and frequency, typically 12 to 16 kHz, and a unidirectional voltage generator (IG) with a trapezoidal wave form. The signal is produced by multiplying (X) the outputs of the two generators. The signal is added (S) to the speech circuit (VC) and sent out on the transmission line. At a point (N) in the circuit (VC) the signal is extracted by a high pass filter (F) to eliminate speech, and then rectified (/v/). The rectified voltage is compared (COMP) with a set reference (VREF) and applied to a control circuit (LC) to regulate the trapezoidal voltage generator (FG). This regulation ensures a constant and adequate charge signal amplitude on the line.

Title: Hide drying machine belt centrallisation - by selvedge contact sensors actuating power cylinders for askew position of tensioning roll
IPC: C14B/
Filed: 1975-12-02
Granted: 1981-05-20
Abstract: Centring device for endless belts in machines for the drying of skins and hides is based on two hydraulic cylinders which are attached to the ends of the tensioning roll. Contact feelers at each selvedge can actuate solenoid valves, when contacted by the belt, which sets a hydraulic control valve to pass hydraulic fluid to opposite ends of the hydraulic cylinders. This moves the tensioning roller askew so that the belt slides towards the centre and, in freeing the feeler, cuts off the hydraulic supply. This system can deal even with thick felt belts which are axially loaded by forces depending on the thickness and compsn. of the hides. It is partic. effective if the correction takes place at right angles to the plane of the two rolls.

Title: Changeover unit for railroad switch
Inventor: CLAUDIO SILIANI
IPC: B61L/
Filed: 1989-07-26
Granted: 1992-02-17
Abstract: The unit comprises an electric control motor able to actuate, through a speed reducer, a sliding rack intended to be connected to the frame of the switch tongues. Such a reducer is of the differential type and has a conductor element coupled to the shaft of the electric motor, a first guide element coupled to the rack, and a second guide element to which is coupled an elastic device generating a resistant couple. Such a device applies to the second guide element a resistant couple sufficient to keep it locked, and to permit the rotation of the first guide element and the consequent displacement of the rack, while the electric motor is actuated to determine the displacement of the said tongues of the switch from the one to the other working position. When the first guide element is locked, the elastic device generating a couple permits the rotation of the associated second guide of the differential reducer, applying to it a reducing or increasing couple. The electric motor can then be deactivated as soon as the resistant load applied to the said second guide element returns to a predetermined value.Figure 1.

Title: Aluminium electrical generator for bicycles, tricycles and similar
Inventor: ANIELLO GERARDO D
IPC: H02K/
Filed: 1988-03-04
Granted: 1992-06-02
Abstract: Described herein is an electrical generator for bicycles. It is constituted of particular components properly assembled providing a small electric machine, which transforms mechanical energy into electrical energy. This generator has been studied in such a way as to take advantage of almost all the useful space. The transfer (space between stator and rotor) has been reduced to provide the maximum yield. It is capable to a power exceeding 3 Watts, indispensable for feeding the frontal and rear lights of the bicycle. The frontal light of the bike absorbs 2.4 Watts, the rear absorbs 0.6 Watts. Another important characteristic of this generator is that it begins to provide very high electrical voltage after only a few wheel rotations, and therefore lighting the lamp at only 5 Km/h; while at an elevated velocity, as for example downhill, the voltage never exceeds 6.7 volts, so as to avoid frequent surges to the lamp. The voltage for bike lights is 6 V. Another advantageous characteristic of this generator is for manufacturers of bicycle light installations, and that of being able to be automatically assembled, thanks to the study of new particulars, of which include: - wireless cast iron roller; - wireless rectifying shaft; - self-lubricating bronze flanges; - spring cover; - the entire click mechanism; - the enclosure seemed at the bottom.
Patent IT-1225995-B (IT)
Title: Mechanical-physical evolution principle in and for the inside closure of ski boots having the structure integrally evolving and intermediate between the inside and the outside
Inventor: RUMONATO PAOLO
IPC: A43B/
Filed: 1988-07-27
Granted: 1990-12-10
Abstract: The mechanical-physical evolution principle as in the title can be stated with the assistance of two correct bases, which are integral to each other but completely different.  The principle is the Cartesian rule, which for co-ordinates has the sole of the foot, which rests on the sole of the ski boot as the horizontal co-ordinate x and the fitting area of the neck of the foot at the front of the foot of the leg-guard of the ski boot forming the vertical y co-ordinate.  The extremes of this system are the final mobile points of all the directions intervening from all the straight lines which are not those resulting from forces as will be described here below.   These straight lines describe the space in the ski boots of all the skier's movements.  Since these movements are curved, this is how the straight lines are transformed as they describe the space in evolutes to then fall-out to find themselves as in an entirely different seat from the the original one.  That is to say, a straight line or a group of perpendicular straight lines can be then found to be horizontal or vice-versa; it starts from that and the evolute movement is produced.  The second basis is the group of vectorial physical forces, which causing the movements, create the progressive movements of the mobile structural parts of the ski boot from their original resting points, which are found to be replaced without a gap until on return (or static position) , conditioned by the initial recomposition of the forces, acting as above described, in the ski boots.  It is possible to deduce from this data the relative synergic conjugation which requires some equitable constructive geometry to be adhered to.  Conjugation forms the basis of the patent such as: involutes with their evolutes in relation to the composition of the oscillatory movements creating variables on the site of the points of support in the evolutes.
