Title: Improvements in or relating to viscous vibration dampers for shafts
Inventor: THORN JAMES DOUGLAS
IPC: F16F15/16
Filed: 1951-11-23
Abstract: 712,641. Torsional-vibration dampers. RUSTON & HORNSBY, Ltd. Feb. 23. 1953 [Nov. 23, 1951], No. 27588/51. Class i08(3) A torsional-vibration damper comprises a fluid-tight casing B rigid with the shaft A, two or more circumferentially-spaced driving pegs 10 secured to the casing walls, a mass 8 having holes 11 corresponding to, but of greater size than, the pegs, and a viscous fluid filling the remaining space in the casing. Torsional vibrations of the shaft A are damped by relative movement of the mass 8, casing B, and the interposed fluid The relative movement is limited to an amount which equals the difference in the diameters of the pegs 10 and holes 11. As shown, the mass 8 is, annular. The casing is annular, and fabricated from end plates 3 and 4, and inner and outer rings 5 and 6. The casing joints may be secured by welding instead of bolts 7. Alternatively, an annular channel-shaped casing may be closed by a single end plate. There are six holes 11 in the mass and respective pegs 10. The latter are secured at end plates 3, 4 by a nut 15 and set bolt 16. Washers 18 are partly countersunk into the end plates and thus prevent contact between the side faces of the mass 8 and the end plates. The pegs 10 may alternatively have reduced diameter threaded portions at both ends, and the washers 18 may be disposed on the reduced-diameter portion's. Holes 17 are bored transversely in the pegs 10 (but these holes may be omitted). A rod, Fig. 4 (not shown), may be mounted coaxially in the peg 10 having holes positioned to correspond with the holes 17. The rod is rotationally adjustable, thereby providing an adjustment to the effective area of the holes 17. In the construction shown in Fig. 5, the peg 10 is secured at one end, only, to the casing. An annular sleeve 26a is in threaded engagement with the peg 10 and its axial position may be adjusted and then locked by means of a nut 27. The aperture in the end plate 4 through which the sleeve 26a projects is sealed by a gland 28. The action of the damper may be varied by axial adjustment of the sleeve 26 or by replacement of the sleeve 26 by another sleeve of different diameter. Alternatively, provision may be made for replacement of the peg 10 by a peg of different diameter. The central portion of the peg 10 shown in Fig. 1, may be of reduced diameter, Fig. 3 (not shown). The casing B and mass 8 may alternatively be of cylindrical shape. In this case, the shaft A may extend through the casing and through a hole bored in the mass 8. The fluid (which is a silicone) may be introduced into the damper after assembly. Alternatively, the casing B assembled except for one end plate and disposed horizontally may be filled with fluid before the mass 8 is placed in position. According to the Provisional Specification, the sleeve 26 of Fig. 5 may be in threaded engagement with the hole in the mass 8, instead of with the peg 10. A fluid reservoir may be formed in the shaft or in the mass 8.

Title: Automatic remote meter reading

IPC: H04M11/00
Filed: 1970-06-10
Abstract: 1,267,793. Collecting data over telephone systems. INTERNATIONAL STANDARD ELECTRIC CORP. 10 June, 1970 [19 June, 1969], No. 28095/70. Heading H4K. Data, such as the identity and total of a public utility meter, is sent to a central processing station over a telephone network and at timed intervals, such as two or four weeks, by means of a telephone substation attachment which at each expiry of a timed interval dials the processing station and in response to an acknowledgement signal sends the data. The period between meter readings is timed by an electrochemical device which deposits silver from an electrolyte and the current through which stops when all the silver has been deposited on one electrode, reversal of the electrodes reversing the process of deposition to time a further interval. Such a timer 25 sets a latching circuit 33 which operates a relay 35 to sense the free/busy condition of the substation telephone line. If the line is busy the circuit waits. If or when the line is free it is looped by operation of a relay 48 and a period of 3 seconds is timed at 46 to presume receipt of dial tone before a motor driven multifrequency number sender 20, 21, 22 is operated to dial the number of the processing station. From the beginning of sending a timer 63 waits for an acknowledgement audio frequency signal from the processing station as detected over filter 72 and triggers 73, 74. Receipt of the acknowledgement in time resets the timer 63 and causes the meter 23 to send its identity and total. If the data sent by the meter is not satisfactory the processing station sends a repeat of the acknowledgement signal to reset timer 63 once more and obtain a repeat of the data. When satisfied the processing station sends an audiofrequency shutdown signal which over filter 81 and trigger 82 resets the latching circuit 33. If timer 63 times out before an acknowledgement signal is received, or when the call is blocked or misdirected, the telephone line is released by dropping relay 48 momentarily before reseizure and a further attempt to set up the connection. Such attempts are repeated until acknowledgement and shut-down signals are received. The attachment withdraws by releasing relay 48 if during its sending function a call is originated over the line by the associated substation. The attachment renews its attempt to send as soon as the substation frees the line. The attachment is locally powered but may be powered over the exchange line.
