Abstract: 1,168,109. Electronic musical instruments. M. TIELAND. 14 Oct., 1967, No. 46949/67. Heading G5J. In a tone source for an electronic musical instrument a sine-wave oscillator is followed by a non-linear amplifier to obtain a signal rich in harmonics, and two frequency dividers, the tone signals being derived from the combination of the outputs of adjacent stages in pairs. A single transistor 1 is used in the oscillator which is tuned by a centre-tapped inductor 2 and capacitor 3. The output from the oscillator is taken to the base of a transistor 10 which operates in the non-linear mode and also to a resistor 14 where the output from the oscillator is combined with the output from the non-linear amplifier through resistor 15 across a resistor 16 connected to output terminal 17. The output from the non-linear amplifier is connected to two frequency dividers consisting of bi-stable multivibrators which successively halve the frequency. The outputs of these stages are also connected in pairs through resistors 28, 29 and 42, 43 across resistors 30 and 44, respectively, to terminals 31 and 45, respectively. Amplitude vibrato can be obtained by varying the bias on transistor 1 through resistor 8 from a terminal 7.

Abstract: 1391413 Brakes actuated by over-running of driven shaft; full-face disc brakes INTERNATIONAL HARVESTER CO 10 Oct 1973 [10 Oct 1972] 47307/73 Addition to 1361330 Heading F2E An agricultural implement provided with a braking mechanism comprising a braking surface 240, Figs. 1, 3, a drive member 245 movable into engagement with the braking surface, and a driven member 212, the drive and driven members being so constructed and arranged that if, in use, the driven member overruns the drive member, the drive member 245 moves into engagement with the braking surface 240 and co-operates with the driven member to reduce its speed, is characterized in that the braking surface 240 forms part of a brake member 236 which is resiliently mounted, e.g. on a wave spring 235, Fig. 5, with respect to the drive member 245 so that the peak torsional stresses developed in the drive and driven members during braking are less than would occur in the absence of the resilient mounting. As shown, a frusto-conical drive member 245 has fixed (e.g. welded), to it a dust shield 250 and pulley sheaves 151, 252, together forming a drive assembly. When the pulley is driven in a direction which is counter-clockwise when viewed from below, the drive assembly climbs up a helical rib 241 on driven shaft 212 until the uppermost edge of drive member 245 abuts spacer 248, and eventually shaft 212 is driven through washer 244 secured by nut 243 to the shaft. When drive to the pulley 251, 252 is discontinued, the momentum of the cutting blade 223 causes shaft 212 to over-run the drive assembly, whereupon this assembly descends down the helical rib 241 until the conical braking surface 247 on member 245 engages conical surface 240 on brake member 236. Brake member 236 cannot rotate because of engagement of its lugs 237 with indentations 238, but it is forced down, causing deflection of wave spring 235. Initial engagement of the conical surfaces rapidly increases the speed difference between drive and driven members so the brake is self-energizing. A dust cover 253 held in sheave 252 by a spring strip 254 forms, with 0-ring seal 255, a lubricating-grease reservoir.

Abstract: 473,791. Cash registers. VIGNEAULT, L. July 31, 1936, No. 21221. [Class 100 (iv)] [Also in Group XIX] Hammer-impression arrangements.- In a key-set, crank-operated machine the items are printed on a voucher strip by item type-wheels, these wheels being connected during their restoring movements to totalizer typewheels which thus accumulate the items and subsequently print the total on the strip in an operation in which a total key is depressed. The totalizer comprises a series of typewheels 8, Fig. 1, mounted on a shaft 9. The shaft is carried by a frame mounted for horizontal reciprocation, whereby pinions 12 rigid with the type-wheels are engaged and disengaged with actuator gears 6 permanently in mesh with pinions 5 rigid with item type-wheels 1. These latter wheels are set by the keys during each item-entering operation, in known manner, and are restored towards the end of the operation after the impression has been made. During the restoring movement, the totalizer is engaged with the actuators 6 to receive the item. Each type-wheel is' provided with two sets of type 0 ... 9 arranged in series. The voucher strip 84, Fig. 11, with its ink-ribbon 83 passes beneath the item type-wheels 1 and the totalizer type-wheels 8. During each item-entering operation, a platen 75 is raised to impress the strip against the type-wheels 1, the platen being actuated by a cam 63 mounted on a hub 62 of the main printer shaft 56. In a total-taking operation, however, the depression of the total key shifts the hub 62 axially of the shaft to disable the cam 63 and render effective a second cam 64 on the hub, whereby a platen 76 is actuated to impress the strip against the totalizer type-wheels 8. A record strip 87, Fig. 8, with its ink-ribbon 88 passes over the item type-wheels 1 and is impressed thereagainst at each operation by a roller platen 94 carried by a frame 90-91 rockable about a shaft 89. The platen is actuated from the printer shaft 56 by a stud 107 that projects from a gear 108 into the path of an offset portion 106 of a lever 104 connected, through the linkage shown, to a slotted arm 98 that embraces a stud 92 on the platen frame. A stop 92a carried by the platen frame aligns the actuators 6 during printing.
