Title: Improvements in or relating to variable-speed power transmission mechanism
IPC: F16H9/16
Filed: 1944-04-25
Abstract: 582,213. Variable-speed gearing. KEARNEY & TRECKER CORPORATION. April 25, 1944, No. 7693. Convention date, May 12, 1943. [Class 80 (ii)] In variable-speed gearing having a pair of belt-connected expanding pulleys each pulley may be locked in a predetermined position while the other is adjusted throughout its range of variable diameter. As shown, applied to the drive of a milling machine, a driving pulley 23 driven by a motor 20 which is slidable on its frame 16 is connected by a belt 22 to a pulley 24 on the cutter spindle 17. The pulley checks 25, 26 which are urged towards one another by a spring 57, have slidable sleeve hubs 27, 28 connected by a link 37 to equalize the expanding movement between the two parts. The link 37 is pivoted at 34 to the spindle 17, passes through slots in the hubs 27, 28 and has pins 42, 46, engaging the side walls of slots in the hubs. The hub 28 has a cap 58 with a bayonet notch 67 engaged by a pin 61 in a sleeve 62 on the pulley half 25. When the checks 25, 27 are nearest one another the caps 58 can be turned to lock them together. Both driving and driven pulleys are of similar construction. In operation, the pulley 24 is locked in its greatest diameter position the pulley 23 being unlocked at its smallest diameter. The pulley 23 and motor 20 are then in the extreme right hand position, Fig. 1. Movement of the motor 20 to the left by rotation of a screwed spindle 72 causes the pulley 23 to gradually increase its diameter until the maximum diameter is reached and the gearing is then at a one-to-one ratio. The pulley 23 is then locked and the pulley 24 unlocked whereupon the motor is moved to the right so that pulley 24 gradually decreases its diameter. The speed of the driven shaft is indicated by a double scale 74 on the motor casing and fixed pointer 75. In a modified type of pulley the spring 57 is replaced by a spring acting both in compression and torsion.

R. ; 2476, Elm Place, both in New York, U.S.A.) March 10, 1930, No. 7788. Convention date, April 30, 1929. Addition to 332,284, [Class 40 (v), Wireless signalling &c.]. [Classes 40 (iii) and 40 (v).] In a system comprising a plurality of television transmitters, Fig. 6, the frequency components of one set of signals are interleaved with, or lie between, the frequency components of another set of signals throughout a range of frequencies, which is transmitted on a single channel 100. The speeds of scanning discs 21 are so arranged that, above say 5600 cycles, the respective frequency groups, which lie close to harmonics of the corresponding linescanning frequency, are more than 200 cycles apart. All the signals from one transmitter 20 are passed through a transformer 80 to a high-quality line 100, and the signals above 5600 cycles from the second transmitter are passed to the line through a filter 140 and a transformer 141. The signals below 5600 cycles from the second transmitter are passed through a filter 130 to a low-quality line 120. Oscillators 94 produce synchronizing frequencies between the frequency groups on the two lines. At the receiver, Fig. 7, the synchronizing frequency on the line 100 is abstracted by a filter 220, and the frequencies of one set of signals are passed to a receiver 280 through filters 231 .. 235, and the frequencies of the other set of signals are passed to a second receiver through filters 236, 237, 238. Alternatively a low-pass and a high-pass filter are n parallel and the latter is followed by harmonic band-pass filters for selecting the frequencies appropriate to each receiver, Fig. 8 (not shown). According to a modification the scanning speeds are so chosen that as few as possible of the frequency components overlap, Figs. 1 and 5 (not shown), and all the signals are transmitted over a single circuit. The signals may be applied direct to each receiver, when the interfering signals appear as a moving mottled background, or the signals are separated by filters except for the interfering frequencies, or the interfering frequency bands are eliminated at the transmitter. The frequencies of one set of signals in the range in which interference occurs may be changed, for example by modulation by a carrier frequency, to a value different from, for example higher than, the frequencies of the other set of signals. The signals may correspond to two objects at the same or different stations or to the same object for stereoscopic or colour reproduction or for simultaneous transmission of separate areas.
