Title: Improvements relating to propellers
IPC: B64C11/34
Filed: 1931-11-05
Abstract: 393,622. Air-screws. MACALUSO, E., 35, Via San Domenico, Turin, Italy. Nov. 5, 1931, No. 30690. [Class 114.] In a propeller for automatically varying pitch in accordance with varying aerostatic conditions, the propeller blades are mounted through universal joints on a carrier mounted on the propeller hub, and toggle links carrying centrifugal masses so connect the carrier and the hub, that variations of the angle L between the hub and the carrier effect a proportionate rotation # of the blades on their axes. A hub 1 keyed on the engine shaft carries the looselyfitting blade carrier 2 which extends into a cruciform member 6, two arms 7 of which are slotted at 33, Fig. 4, and are engaged by rollers 32 of toggle levers 13, linked to the second member 12 of the toggle which is weighted at 31 and pivots in bearings 11 on a flange 2 of the hub. A bearing 18 for each blade is trunnioned at 17 in the other arm of the cruciform member 6 in an arm of a member 8 of the blade carrier. A yoke 21 attached to the root 22 of the blade 23 works against a ball 19, further balls being interposed between it and the curved bearing 18. A cross-bar 24 on the hub 1 is connected by four-pronged forks 25 gymbal-connected to the yokes 21 through the intermediary of spherical joints 27 and sliding seats. The angular movements of the propeller blades under centrifugal forces is thus accompanied by a change in the pitch angle through the operation of the mechanism associated with the cross-arm 24, which is fixed to the hub. The adjustment of the position of the toggle-link 13 relative to the arm 7 by means of the roller 32 and slot 33 permits the so-called efficiency curve to be varied. A plate 42 axially slidable on the hub can be adjusted by the pilot through suitable mechanism. A steep-pitched nut 40 carried thereby thus angularly displaces a spindle 39 and which through levers 36, 37 adjusts the position of the toggle link 13. The variation in the movements of the aerodynamic forces acting on the blades is compensated for by the linkages 43, 44 attached to the root of each blade and cradle 20 respectively. The unevenness of the propelling force couple is smoothed out by the beam 46, Fig. 2, loosely mounted on the hub and carrying a pinion 16 meshing with quadrants 15 and combined with an arrangement for imparting to the beam 46 the angle alpha reversed and amplified.
Patent GB-812581-A (GB)
Title: An improved apparatus for the application of lengths of fabric to the drums of tyre forming machines or the like
IPC: B29D30/30
Filed: 1956-10-10
Abstract: 812,581. Tyre building apparatus. CONTINENTAL GUMMI-WERKE A.G. Oct. 10, 1956 [Oct. 11, 1955], No. 30825/56. Class 144 (1). In a tyre-building machine, each fabric ply 4 is wrapped around the building drum 2 by a longitudinally movable conveyer belt 3 upon which the ply is laid, one end of the conveyer belt being attached to, or guided around, a rigid roller 6 mounted parallel to, and pivotal about, the drum axis, whereby rotation of the roller 6 about the drum axis in the direction of arrows 10, winds the belt 3 and therefore the ply 4 around the drum periphery. As shown the belt 3 is of finite length with its end remote from the drum 2 stored on a spring-loaded roller 1 and with its end adjacent the drum guided over a support roller 5 fixed parallel to, and in the horizontal plane containing, the drum axis and then attached to the roller 6. The roller 6 is rotatably supported between arms 8 journalled on the drum-shaft 9. In operation a bias-cut ply 4 is accurately positioned on the belt 3 with the aid of markings 11 on the belt, and the arms 8 and drum 2 rotated in unison to wind the ply, without slip, on to the drum. When the roller 6 reaches the limit of its rotation about the drum axis, as shown in Fig. 2, and in broken lines in Fig. 1, the roller 6 is rotated about its own axis in the direction of arrow 12 to wind up the belt 3 and thereby continue feed of the ply 4 on to the drum periphery until the bias-cut ends 4<SP>1</SP> of the ply 4, Fig. 3, abut. Take-up of the belt 3 on to its roller 1 is effected on reverse rotation of the roller 2 and arms 8. If an endless belt conveyer is used the rollers 1 and 6 constitute the end reversing rollers and either roller 1 is mounted for movement towards and away from the drum, or a compensating loop is arranged in the return run of the belt, to permit the displacement of roller 6 about the drum axis. In a tyre pocket or belt forming machine, the drum 2 may comprise two interfitting cylindrical axial halves which are separable for withdrawal of the formed pocket.

Title: Character recognition system
IPC: G06V30/262
Filed: 1974-07-12
Abstract: 1437586 Character recognition systems INTERNATIONAL BUSINESS MACHINES CORP 12 July 1974 [25 Oct 1973] 30879/74 Heading G4R The system includes recognition units which respectively determine, for each scanned character, both the alphabetic character and the numeric character (here called the read characters) which most closely match the scanned character. The read characters address stores which contain tables of probability factors. The factors of one table indicate the probability of a read alphabetic character being a misrecognition of a scanned numeric character (which should appear as the read numeric character), and the factors of the other table the probability of a read numeric character being a misrecognition of a scanned alphabetic character. The factors read from the store are used to determine whether the read alphabetic or the read numeric character is more likely to be correct. The embodiment described examines groups of read characters, the groups forming for example the name and address on a postal item, and being separated by an interword space. The characters are scanned, normalized and segmented, and the lines in which the characters lie (e.g. the house number and road will be in line 2) are determined by known means, not described. Character features are extracted and passed to two recognition units which provide signals representing the read characters. If the number of rejects, i.e. characters which the recognition unit failed to identify, in the read alphabetic group is more than one greater than those in the corresponding read numeric group it is assumed that the read numeric group is correct, and vice versa. However if there is not a significant difference in the number of rejects the probability stores are both addressed by the sequence of read alphabetic and corresponding read numeric characters so as to produce, from each store, a sequence of probability factors. The factors of each sequence are multiplied together and the resulting two products compared to determine whether the alphabetic group of the numeric group is more likely to be correct and to gate the relevant group to a utilization unit. Before comparison takes place the probability products may be weighted by further factors which are selected from stored values in accordance with the line in which the group lies and in accordance with the position of the group within the line, e.g. the first group of the second line of an address is expected to be numeric.
