The voltage drop U 0  across the resistor 4 is applied to a switching circuit (not shown) which switches off the apparatus 1 when the voltage U 0  falls below a predetermined value due to reduction in the resistance of the resistor 4 as it heats up on cessation or reduction in the flow of coolant fluid.
Patent GB-105753-A (GB)
IPC: B63B39/04
Abstract: 105,753. Norden, C. L. April 15, 1916, [Convention date]. Gyroscopic apparatus.-Means are provided in stabilizing-apparatus for limiting the angular velocity of precession when it attains or exceeds a predetermined magnitude. The frame carrying the precessing rotor is provided with means to couple automatically the spinning rotor to the body to be stabilized so as to transform energy of oscillation of the body into energy of rotation of the rotor. In the construction shown in Figs. 1 and 2, the vertical rotor shaft 2 is connected by worm gearing to two horizontal shafts 5 mounted in the frame 35, which precesses about horizontal trunnions and carries a shaft 11 connected by a pinion 10 with a rack 8 secured to the body to be stabilized. As the frame 35 precesses, the shaft 11 is made to rotate, the speed and direction of rotation changing with the speed and direction of the precession. The shaft 11 is geared to shafts 5 by the gear 12 meshing with pinions 15, loosely mounted on shafts 5 and fast with clutch sleeves 16 loose upon shafts 5 and automatic coupling occurs when one of the gears 15, 16 is turned by the movement of precession faster than its shaft 5, ratchets 20 fast on the clutch sleeves 16 engaging pawls 19 pivoted on plates 17 fast with shafts 5 and so causing a clutch band 16 to clutch its shaft 5 frictionally. In another construction, the rotor shaft is geared to a shaft made to rotate by the precession in the same manner as the shaft 11 through bevel-gearing, which becomes coupled to the precessiondriven shaft bv friction clutches whenever the speed of precession exceeds a predetermined magnitude. An hydraulic control system shown in Fig. 7 comprises a variable-stroke hydraulic pump 36 driven by the precession movements and connected to an hydraulic motor 38 geared to the rotor shaft 2. Fluid is drawn by pump 36 from pipe 44 and delivered through pipe 43. At a certain pump speed, a spring-loaded valve 42 in pipe 43 is closed and the fluid from the pump 36 drives the motor 38 and so the rotor shaft 2.

A tube drawing apparatus having a die 12 and a plug 16 has a transducer assembly 24 for vibrating the plug and a transducer assembly 38 for vibrating the die. When the length of tubing which has been drawn is “-wavelength of the speed of sound in the material being drawn, at the operating frequency, there is a drop in the drawing tension necessary and thereafter the drawing tension decreases momentarily as the length increases by half-wavelengths. To take advantage of this effect and thereby maintain the required drawing tension at a minimum, a second die 80 is adjustably mounted on the apparatus. The second die is moved to a position “-wavelength from the first die 12 so that a permanent condition of resonance obtains in the section of tubing between the two dies. Further dies may be positioned at half-wavelength intervals beyond the second die. The second and further dies are dimensioned so that they produce a slight sinking effect on the tube.

Abstract: 768,783. Printing-machines. GRAFISKA MASKIN AKTIEBOLAGET. April 19, 1955, No. 11273/55. Class 100(2) A reciprocating bed printing press provided at its ends with one or more brake or buffer cylinders for absorbing the retarding forces at the reversing points of the bed is characterized by the provision of one or more regulating cylinders 1 connected by conduits 18 with the brakes or buffer cylinders, each regulating cylinder containing a piston 3 arranged to move against a spring 5 by compressed air forced from the brake or buffer cylinders, from one to the other of two predetermined positions in which the piston is retained by a locking device. The piston 3 has a piston rod 4 provided with a groove 17 which co-operates with bolts 12 and 13 to retain the piston in either one of two positions A and B. The bolts 12 and 13 are connected with a three-armed lever 14, 15 attached to a spring 16. The positions A and B of the piston correspond to different printing speeds, since the necessary retarding force to be applied to the bed varies with the speed of the bed; the variation in retarding force is provided by the different positions of the piston 3. When the press is operating at high speed the piston is in the position A. When the press speed is reduced the arm 15 is rocked to the left, e.g. by a Bowden cable. The bolt 12 is pulled from the groove 17 and the piston 3 is moved' to left by air pressure against the action of the spring 5 and locked there by the bolt 13. When the press speed is increasd the bolt 13 is removed from the groove 17 upon release of the arm 15, thus allowing the spring 5 to move the piston 3 to the right into the position A.
