Title: Improvements in or relating to indicating systems
IPC: G01R13/28
Filed: 1944-01-27
Abstract: 595,449. Telemetering. CURTIS PUMP CO. Jan. 27, 1944, No. 1547. Convention date, July 9, 1943. [Class 40 (i)] In an indicating system a number of signals, each varying in intensity with a quantity to be measured, are applied over a single channel to a receiver, preferably a cathode-ray tube, having a similar number of indicating means and scales. As shown in the Figure, differing low-frequency inputs 109-112 are varied in amplitude in response to the condition to be by means of the movable contact elements 105-108 and applied through isolating resistors to a single pair of conductors. At the receiver, the signals are segregated by means of tuned circuits, each comprising an inductance 148 and condenser 149, each circuit being tuned to one of the input frequencies. The signals are then rectified and applied to the deflector plates 23-26 of cathode-ray tube 10. In a modification, Fig. 3 (not shown), the signals modulate a high-frequency carrier wave which is transmitted to a receiving station where the modulated carrier wave is demodulated and the signals segregated in a similar manner to Fig. 2.

Abstract: 1402961 Feeding sheets MERKUR BETEILIGUNGS-GmbH [trading as WEITMANN & KONRAD] 11 Jan 1973 [21 Jan 1972] 1553/73 Heading B8R Sheets are fed from the top of a pile 100, Fig. 1, by means of rollers 102, 103 and a belt 105 against a pivoted registering front stop 109, and thereafter to a printing-machine, and the presence or absence of sheets at the registering position is detected by two laterally spaced light-sensing means 110, which actuate control means to stop the printing machine and sheet feed, or to start or stop printing by bringing cylinders 107, 108 together or apart, according to the presence or absence of a sheet at particular times, the sheets being fed in overlapping relationship. During each machine cycle, the sensing means are enabled to actuate the control means at three specific moments A, B, C, corresponding to early, correct and late arrival of a sheet at the registering position. Two discs are mounted on a shaft 116, Fig. 3a, rotating in synchronism with the machine, the discs carrying cams 112, 113 which pass switches 117, 118 and inductively influence the latter at moments A, B, C. The electric control circuit, (Figs. 5a and 5b, not shown) includes a storage means which is set in one of two states, according to whether the printing-machine is being operated normally, or is being started (i.e. the first sheet has not yet reached the registering position). During normal operation, detection of a sheet at moment B causes printing to take place. If the sheet is askew, it is detected by only one of the two sensing means and the machine is stopped. If there is no sheet present at moment B, the machine is stopped. During starting, if a sheet is detected at moments A or C, or is detected askew, the machine is stopped, but detection of the absence of a sheet at moment B does not stop the machine.

Title: Improved method of balancing rotary machine parts
IPC: G01M1/04
Filed: 1921-01-10
Abstract: 157,959. Schenck Eisengiesserei und Maschinenfabrik Darmstadt Ges., C., and Heymann, H. July 6, 1916, [Convention date]. Testing balance of rotary apparatus.-Relates to a method of balancing rotating bodies by means of a pendulatory mounting, especially applicable to crank-shafts, in which a single mass is applied, in the line of intersection of a radial plane and the plane of action of the oscillating moment resulting from all excess balance'forces, so as to balance the said moment, whereafter the bearings of the machine are interchanged and another compensating mass is applied in the immediate vicinity of the plane of the unbalanced force to balance the residual moment still existing, and the process repeated till the excess balance force is small. A body B with unbalanced forces P, Q, acting in planes distant p, q, from an axis of oscillation y, y, can have imaginary forces Q1, Q2 and P1, P2 equal to the forces P, Q, respectively, impressed at the bearing point C, as shown, without disturbing the balance, and the forces P1, Q1, compounded to form a resultant R, the couples P, P2 with arm p and Q, Q2, with arm q being compounded to form an oscillating moment M1. The oscillation of the shaft is stopped by a mass m1, applied in the plane f, such that the product of its centrifugal force, i.e. K1 and the arm K balances the moment M1. The residual unbalanced force is R1, the resultant of K2 and R. The bearings A, C of the machine are now interchanged so that the axis yy is in the bearing A. The oscillations set up by R1 about yy are eliminated by a mass m2 with centrifugal force equal to H applied in the plane b, and the residual unbalanced force is a pressure H-R1 in the bearing A. By arranging the plane b in the immediate vicinity of the bearing C, the unbalanced force becomes smaller at each interchange.. As applied to crank-shafts with cranks in different planes, the balance masses are applied to the sides of the web adjacent to the bearings, the practical difficulty due to the nearness of the crank-webs being overcome by fitting an extension sleeve over the journal. Should the points of application of the balance masses not fall in favourable positions on the crank webs, they can be artificially shifted by the additon of other balance masses.
