Title: Improvements in and relating to chain and like drives
IPC: F16G5/18
Filed: 1931-03-06
Abstract: 373,679. Belt gearing. HEINDL, R., 1, A Via Giustinelli, Triest, Italy. March 6, 1931. No. 7003. Convention date, March 6, 1930. [Classes 80 (i) and 80 (ii).] In belt gearing, the belt, which may be of link or rope form, or the V-pulley, or both, carries balls, rollers, or pivoted or rocking segments acting in ratchet-clutch manner to produce a non-slipping drive in one or both directions of drive. The invention is applicable to expanding wheel variable-speed gearing. The belt members 6, Fig. 5, which may be interconnected by links 3, are formed with inclined flat or curved surfaces 8, 8<1> supporting balls or rollers 7 of cylindrical, conical, barrel, or other form centred by springs 9 and engaging the walls 4 of the V-pulley. The rollers &c. move along the surfaces 8, 81 and jam between the pulley walls. Friction plates, centred by the springs 9, may be arranged between the rollers and the walls 4. The walls of the pulley, which may be flat or curved, may be inclined to the central plane of the pulley at less than the angle of friction to prevent the belt from riding radially outwards, or may be restrained from such movement by the pull of the belt. The faces of the rollers 7, Fig. 13, may be struck from eccentric centres, as shown, when the members 6 may have flat faces. In another form, Fig. 15, segments 7 turn on separate or common pivots 34 in the member 6. Radial lugs on the members 6 may engage a slot in the base of the pulley groove to prevent tilting of the belt. As shown in Fig. 25, the rollers 7 and enclosed surfaces 8 may be arranged in the pulley 5, or in both the pulley and the belt. In the expanding-pulley gear shown in Fig. 22, the cones 49, 53 are secured to their shafts 47, 48, and the cones 50, 52 are adjusted by levers 55 actuated by a screwed rod 59. Lugs on the belt members engage in grooves 43 in parts 63 loose on the shaft to prevent belt tilting. One or both of each pair of cones 49, 50, Fig. 23, may be adjusted by a nut 65 carrying a spur wheel 80 geared by idlers 67 on stationary spindles 68 to a wheel 70 also geared by pinions 71 on a bevel wheel 73 to a wheel 74 secured to the shaft 47. Rotation of the wheel 73 turns the nut 75 relatively to the shaft 47 and changes the gear.

Abstract: 1,051,607. Grinding crank-shafts. K. GOLTEN and S. GOLTEN. Feb. 20, 1964. No. 7154/64. Heading B3D. A machine for grinding crank-shafts of large marine engines comprises one or more grinding bridges 15 which are adjustable axially and radially of the shaft and carry units 14 having grinding wheels 13, the machine being adapted to be movably attached to the main bearing of the shaft so that the machine will follow the journal if the rotational axis of the journal is displaced in relation to the axis of the main bearing during rotation of the crank-shaft. When the journal 1 of the engine requires grinding, the upper half of the bearing and the lower part of the bushing are removed so that the journal is unsupported. A pair of half rings 2 are spaced apart by bolts 10, 11, 12, the bolts 10 being connected by rods 5 to stationary parts 8 of bolts for the bearing. Springs 6 act on nuts 9 on the rods to press guides 4 mounted on the half rings against the unworn parts at the ends of the journal. The bolts 11, 12 act as guides for the bridge 15, bolt 11 being embraced by a bushing at one end of the bridge, and bolt 12 being engaged by a clamping member 19 which passes through the bridge and has a spring 20 pressing the bridge towards the bolt. A screw 18 engaging the bridge is adjustable to raise and lower the bridge to adjust the grinding wheel radially of the journal. The grinding unit 14 is reciprocatable by a handle 16 in a horizontal direction to remove errors caused by wear of the grinding wheel. If all the journals of the crank-shaft are worn, every second journal is exposed and a machine as described above mounted on each exposed journal with the guides 4 engaging the unworn parts of the journals so that, when the crankshaft is rotated, the journals are ground true with their original axis of rotation. Two or more bridges 15 with grinding units 14 may be supported on the spacer bolts 11, 12.

Binary data is transmitted in frequency shift form, bits of one significance being represented by frequency f s  and bits of the other significance by f u  or f l  which are symmetrical about f s  and of which one is the carrier frequency. In the system described, Fig. 2, binary data (A), Fig. 1 (not shown), is gated at 11 with clock pulses at bit rate (C1), the resultant pulses feeding a bi-stable circuit 18 whose output (B) is the differential representation of the binary data (A). The differential signals are gated at 19 with the slightly delayed clock pulses (C1), the resultant pulses (P) being added at 27 to carrier clock pulses (C2) at twice the bit rate. The sum of these pulses feeds a bi-stable circuit 32 which gives a square-wave signal (D) having two symmetrical side bands. A filter 34 selects one of the side bands and modifies the spectral density to contain continuous components only. The filter output is duobinary waveform (E) in which Mark bits are represented by f s , the centre frequency of the side band, and Space bits by f u  or f l , one of the latter being the carrier frequency.
