Title: Improvements in the mechanism of speed governor devices
IPC: F03B15/12
Filed: 1924-09-30
Abstract: 245,193. English Electric Co., Ltd., (Seewer, P. W.). Sept. 30, 1924, Centrifugal governors; fluid relays; transmitting-mechanism. - The lever connecting a centrifugal governor to the pilot. valve of a servometer is given rocking movements in two planes one of which moves the valve as the speed changes and the other causes a return movement of the valve due to the movement of the servomotor. The pivot of the lever may be moved to obtain a permanent speed variation with change of load. A rotary casing 8 carries rollers 10 bearing against an inclined surface and a disc 16, loaded by adjustable springs and bearing against one end of the lever 5 through a rod 4 and sleeve 21. A dashpot 27 communicates with the chamber 33. The lever 5 pivoted on the sleeve 44 actuates the needle valve 6 controlling leakage from a cylinder 84. The piston 83 moves a piston valve 82 which distributes fluid to chambers 91, 92 to actuate the distributing valve 61 of the servomotor. Rotation of the. sleeve 44 is caused by the servomotor piston (not shown) to which it is connected through a dash-pot 158. The ends of the lever 5 have an arcuate shape and one or both ends have a cam face 41 so that rocking of the lever due to the servomotor in one plane causes it to rock in the other plane in a direction contrary to that due to centrifugal action, tending to neutralize the first movement of the needle valve 6. This neutralizing movement is carweUed as the movement of the dash-pot 158 returns the lever to its central position. The dash-pot comprises a bracket 159, Fig. 15, to which two cylinders 161 are secured and in which the cylinder 162 is a sliding fit. The pistons 181 are biassed to central position by springs 183 and are attached to a crossbar 168 also connected to piston 167 which has a through passage for fluid controlled by an adjustable needle valve 173. Toothed sectors 157 on the lever 152 gear with racks 158 secured to the cylinder 162 and the crossbar 168 is connected to the toothed sector 51.

Title: Improvements in or relating to machine tools
IPC: F16D43/26
Filed: 1953-08-26
Abstract: 749,706. Friction clutches. SCHULER AKT.-GES.. L. Aug. 26. 1953 [Sept. 2, 1952], No. 23579/53. Class 80(2) A reciprocating machine tool such as a press, &c., actuated on rotation of a crankshaft 1, is driven through a clutch 3 which slips on overload, and the pressure engaging the clutch elements is automaticallycontrolled during each rotation of the crankshaft in such a way that it is reduced during the bottom portion of the crank's rotation when the press, &c., force is at a maximum, and damage due to overload is therefore most likely to occur. The clutch comprises a driving member 2 carrying plates 3, engaged by plates 13, 26, on a hub 5 fast on the shaft 1, when levers 8 are moved pivotally about rollers 7 to move a carrier 10 to the left of Fig. 1. A disc 26<SP>1</SP> on the hub can alternatively be engaged with a brake surface 22 on a surrounding stationary housing 29. The inner ends 27 of the pivoted levers 8 engage a slot 28 in a control rod 14, disposed in a bore in and moved axially of the crank shaft 1 to engage the clutch or brake. The right-hand end of the control rod is fast with a piston 20 in a cylinder 30; pressure fluid is fed to the side K of the piston to engage the clutch, and to the side B to engage the brake. A lever 15 is pivoted to the left-hand end of the control rod and carries a roll 33 engaging a cam 17 adjustably secured to the frame of the press. The raised portion of the cam is arranged to be passed over by the roll 33 as the press is reaching the bottom portion of its stroke, so that the control rod 14 is then moved to the left, against the pressure of the fluid in the cylinder portion K, and thus the clutch can the more readily slip on overload. In a modification (Fig. 5, not shown), the pivoted lever 15 acts on the control rod 14 through a compression spring.

Title: Magnetic device
IPC: G11B5/00
Filed: 1973-05-18
Abstract: 1372516 Moving domain sensing arrangements INTERNATIONAL BUSINESS MACHINES CORP 18 May 1973 [30 June 1972] 23721/73 Heading H3B A bubble domain in a moving domain system is detected at a sensing position by oscillating its size and detecting its effect in a tuned circuit. As shown in Fig. 1, a bubble domain 12 in an orthoferrite or garnet plate 10 is biased by a field Hz, and is propagated by an in-plane rotating field H along T and I bars 20 to a sensing position defined by a sense loop 26. Domain oscillation is effected by an A.C. source V AC , and the mean domain size determined by a D.C. bias V DC , both being connected in series with a loading impedance Z1. The sensing loop forms part of a parallel resonance circuit L1, C1 which is resonant in the absence of a domain. When a domain is present in the sensing position, the resonant circuit is detuned by the change in inductance of the sensing loop due to the oscillating domain, and the voltage at point A is reduced. The change in voltage is detected by a circuit, Fig. 3, comprising an amplifier 32, a diode detector 34 and a noise filter R2, C2. In a modification, Fig. 5, the detection circuit comprises a first tuned circuit T1 which includes the sensing loop 26, a second tuned circuit T2 and a coupling amplifier 32. The arrangement forms a Miller oscillator which operates only when the two tuned circuits have the same resonant frequency, the operational condition being detected by a diode 34. In an alternative arrangement, Fig. 7, the sensing loop is replaced by two conductors magnetically coupled when a domain 12 is present, one conductor being in a domain oscillating circuit 26 and the other in a detection circuit 30. A further sensing arrangement, Fig. 8, using separate oscillating and detection circuits 26, 30, comprises a sensing loop 12 and a capacitor formed  by disc electrodes 38A, 38B on opposite sides of the plate. An oscillating domain may also be detected by optical methods. In Fig. 9 light from a helium-neon laser 40, for example, is circularly polarized by a quarter wave plate 42 before striking the domain plate 10. Oscillation of domain size changes the degree of scattering of light passed through the plate to an aperture 48, a photodetector 44 responding to the light transmitted by the aperture and producing an output signal at terminal B. Alternatively an analyser may be located behind the plate.
