摘要:
A device is described for electronic signature of data which can be immediately applied in e-banking and e-commerce or in any system based on electronic signature, with an optical input for receiving data from any computer monitor and with a display for showing the data to be signed. In addition it has a keyboard for interaction with the user and a system for processing the electronic signature. The device is not re-programmable, so that it is immune to possible attacks from viruses or malicious software which could compromise the system security. Moreover, as the data to be signed are displayed the user knows what data he or she is actually signing.

The document feeder for printing equipment as designated here, is designed to draw certain types of document, one by one, from a pile or stock of these to a device which prints certain characters or devices. The pile of documents is constantly pushed towards a set of tractor wheels (10, 11) by the action of a continuous pressure device (7), while the document is passed along the corresponding guide (1) in the direction of the exit (13) between a set of selector wheels (14, 15, 15′, 15˝) equipped with thoroidal rubber bands (16, 17). These are arranged in such a way that the roller (14) on one side of the guide turns in forward direction, while on the other side of the guide (1) another roller (15) with subsidiary rollers (15′, 15˝) connected to it turns in the opposite direction, tending to pull the documents back, thus preventing any documents in contact with it from moving forward. Finally, documents are moved towards the end (13) of the guide (1) by a last wheel set (18) close to the exit point.

A double carriage has been prepared for automatic tool change in core making machines for casting, where there are two sets of motorized rollers capable of receiving and expelling these tools; a carriage where there is a rolling frame, with wheels that are motorized by means of a reduction motor, where there is another reduction motor in each of the two operative sectors which activates the corresponding group of rollers, through an intermediary transmission shaft; in addition the carriage embodies handling devices for the tools in order to permit and facilitate their periodic cleaning. These devices consist of a support on which a tipper arm is assembled, which is activated by a hydraulic cylinder; on this arm there is also a plate, on guides, which contains clamps to secure the box of bores; the plate is moved by a hydraulic cylinder; this structure is a simple one when the carriage is used for boxes of cores of vertical opening and double when these are of horizontal opening.

The invention relates to a transmission for bicycles, which substitutes the conventional transmission by means of a chain, and which consists in a rimcarrier plate (1) related to the pedal shaft (3), to which are stiffened a plurality of concentric rings which engage respective pinions (4) mounted with a freedom of rotation on a tubular transmission shaft (5), within which is established an sliding element, with a diametrical arm, which allows one of said pinions to be blocked at will with respect to the shaft, said guiding rims-pinions group being complemented by a further similar guided rims-pinions group, at the other end of the shaft, which may be selected by identical means and which guided rimcarrier plate (20) transmits the movement through a multiplying planet (23) element and a freewheel pawl (24), to the shaft of an outlet pinion (22) which plays with an engaging track established on the inner side of the rim of the wheel.

The classifier is designed as an addition to an apparatus which prints and/or reads certain types of document, its purpose being to order such documents correctly and independently. To this end the device is equipped which lateral guide elements (15,16) mounted on swivelling shafts (13,14), each activated individually by its corresponding electromagnet (19); the inner edges of the successive lateral guides (15,16) themselves form a guide along which documents may pass straight ahead, while when activated, the outer edge (17) will direct documents towards the requisite side-compartments (26) in the order in which they entered the classifier. This assembly is supplemented by photo-detectors (21,22) at the entrance and exits of the lateral guides (15,16), while there are also sets of traction wheel (4,4′) combined with guide wheels (5,5′) which press against them; the guide wheels (5,5′) are mounted on shafts (3) which are pressed by springs (23) in the direction of the traction wheels (4,4#MIN).

The system is applicable to devices with two cam rests, a slow cam rest and a fast cam rest, provided with a temporising element, and centres its characteristics in the fact that the said temporising element 12, assembled on an oscillating lever 24 moves from the inactive position 13 to the active position 14 by means of the intervention of a selection lever 17 and a clutch 21 which swings about an axis 22 stiffened to the lever 17, whereas the opposite movement, the return movement to the inactive position, is determined by the change in position of the selection lever 17 dragging clutch 21 and which in turn releases the oscillating lever 24, or only by changing the position of the clutch 21. This system, applicable to the field of the household appliances, considerably increases programming capacity.
