Title: Improvements in or relating to pneumatic apparatus for automatically operating musical instruments
Filed: 1922-10-17
Abstract: 210,364. Coldman, H. C. Oct. 17, 1922. Expression-controlling apparatus employing a tension-regulating differential governor or choker provided with a finger-key for accenting by varying the tension, comprises means whereby tune-sheets either with or without accenting holes may be used, the operator in the case of automatic accentuation preferably being able in addition to vary the accentuation by depressing another finger-key, said means consisting of an auxiliary differential governor, and an atmospheric valve connected thereto and to the accent duct in the tracker-bar and controlling the main differential governor. In the construction shown diagrammatically in the Figure, the striking-pneumatics are operated from the high-tension chest 1, and the primary valves from the low-tension chest 2. Two main governor-valves 6 with differential diaphragms 12 and finger-keys 18 are provided, one for the treble high tension and one for the bass, connected as shown to the pump-reservoir 5 and to atmospheric valves 21 which are controlled from accent ducts 46 in the tracker-bar 4 by diaphragms 29. When a sheet without accent-holes is in use, since the duct 46 is covered, the chamber 14 above the diaphragm 12 of a main governor is connected by the valve 21 to atmosphere through the duct 24, and the governor regulates the tension for soft playing. Accenting can then be obtained by depressing the key 18. When a sheet with accent-holes is in use, the valve 21 connects the chamber 14 by pipes 31, 32 to the smaller, but similar, auxiliary choker 33, whose diaphragm 38 is open on the upper side to atmosphere and which is also connected to the pump-reservoir 5. The chamber- 14 is therefore exhausted, giving automatic accentuation, and the degree of exhaustion, and therefore also of accentuation, may be increased by depressing a finger-key 43 on the auxiliary choker. The two main chokers and the auxiliary choker may be arranged beneath the keyboard; and pistons may replace the diaphragms. The cross-section of the lifter 26 of the valve 21 may be of approximately the same area as that of the valve seat, as described in Specification 210,132. Specifications 5812/09, 5011/10,. 14030/10, and 146,608 also are referred to.

Controlling different function by same handle or lever; relay or power apparatus.-Relates to power-driven continuously variable epicyclic gearing for (1) differentially steering, (2) varying the speed, and (3) reversing a motor.vehicle, and shown as applied to an endless-track vehicle. The driving-sprockets 10, Fig. 3, for the chaintracks are driven by the engine shaft 43, Fig. 5, through the usual change-speed and reversing gearing 42, bevel-gearing 36, driving-axle 33, sunwheel 32, normally stationary planet-wheels 30 and internal gears 27. The plant-pinions are mounted on rotatable carriers provided at their inner ends with worm gearing 52, by the rotation of which the planet pinions are rotated relatively to the sun-wheels. The mechanism for effecting this rotation comprises a hand steering- wheel 55 on a sleeve 57 rotatably mounted on a steering-post 54 adjustable on a pivot 56. The sleeve controls, by the arms 58, Fig. 6, rods 60 and yokes 62, a pair of friction cones 46 splined on the shafts 48 which carry the worms 50 for driving the worm gearing 52 and rotating the planet-wheel carriers. The steering-wheel sleeve also carries a loose collar 63 connected bv a rod 64 and yoke 65 to a central friction cone 45 splined on an extension of the engine shaft. By turning the hand wheel to the right or left the corresponding friction gear and planet-wheel carriers are operated for differential steering. By tilting the sleeve the central cone drives both lateral cones, and, according to the amount of slip, gives a varying series of forward speeds, or if by pressure no slip occurs a reverse drive is produced.

For the production of a multicolour stereoscopic effect, a set of photographic records comprising a left pair of photographic, positionally identical records and a right pair of photographic, positionally identical records stereoscopically related to the first pair are made of a subject through filters which are, such that the records of the first pair are made respectively with light of long and short wavelengths, relative to each other, both chosen from substantially one half of the visible spectrum whilst the records of the second pair are made respectively with light of long and short wavelengths, relative to each other, both chosen from substantially the other half of the visible spectrum. The records are then projected in superposition on a screen using for each record, light of a wavelength corresponding to that by which it was made and are viewed through a viewer comprising left and right filters, the left filter allowing the passage of the long and short wavelengths in the said substantial one half of the spectrum and blocking passage of the long and short wavelengths in the said other substantial half whilst the right filter does the opposite. The use of red and orange light for the left pair of images and green and blue light for the right pair of images is referred to. Camera or projector apparatus used in the performance of the invention may comprise four entirely separate cameras or projectors. Alternatively half the number of cameras or projectors may be used, in combination with beam splitters. Filters may be used for separating out light of the appropriate wavelength or, in the case of projectors, suitable sources of light may be used without filters. The invention is stated to be applicable to cinematograph and television as well as still picture recording.
