An arrangement for stretching the tension anchorage rod, connecting the bearing members for the rolls of a rolling mill, in order to relieve stress on the rolls if a bar being rolled has become stuck therebetween, includes hydraulic piston and cylinder means in which one part thereof, i.e. the piston or cylinder, is supported at one end of the rod and the other part, the cylinder or piston, bears directly or indirectly on the other end of the rod, the arrangement being such that stretching of the rod may be effected without applying pressure to at least one of the bearing members. Bearing members 1, 2 for rolls 3, 4 are clamped together, with a distance element 5, by a tension anchorage rod 6 having an adjustable clamping nut 11 screwed on its head 6c and a clamping nut 8 screwed on its other end 6a. The nut 8 and thus the entire roll stand is supported in a bearing cup 10. To stretch the rod 6, without applying pressure to the bearing members 1, 2, hydraulic fluid is supplied to a cylinder 9, defined by the space between the lower end of the rod 6 and the nut 8, to apply pressure to a piston in the form of a tube 7 surrounding the rod 6 and bearing against its head 6c. Pressure on the rolls 3, 4 is then relieved and the nut 11 may be readily released. In a modification, Fig. 2, an hydraulic cylinder 9a is defined by a part 8a on the upper end of the rod 6, an adjustable clamping nut 13 being screwed thereon and a non-adjustable clamping nut 14 being carried on the head 6c at the lower end of the rod 6. The arrangement of Fig. 2 may be used when the rod 6 is in the form of a stay bolt screwed into the lower bearing 2, the head 6c and nut 14 being dispensed with and the tubular piston 7 extending only from the hydraulic means 9a to the upper surface of the member 2 on which, or on a collar on the screwedin part of the rod, it is supported. In an alternative modification of Fig. 2, although the rod 6 is of full length the tube 7 extends only from the hydraulic means 9a to the top of the member 2. In a modification of Fig. 1, the hydraulic chamber 9 is formed in the member 2 and the tube 7 is correspondingly short.

Title: Improvements in or relating to modulated oscillators
Inventor: FORBES MICHAEL JAMES
IPC: H03K4/06
Filed: 1968-07-12
Abstract: 1,270,528. Pulse modulation circuits. E.M.I. Ltd. 14 July, 1969 [12 July, 1968], No. 33256/68. Heading H4L. In an oscillator providing output pulses whose repetition frequency varies linearly in accordance with an input control signal, the input signal V 1  is applied to the base of transistor VT1 which develops equal and opposite voltages across resistors R1, R2 which are applied to the bases of complementary transistors VT3, VT2 respectively. Transistors VT2, VT3 with emitter feedback resistors R3, R4 act as equal constant current sources of opposite polarity, one or other of which is directed by a diode switch D1 to D4 to an integrating capacitor C, the diode switch being operated by the output of a differential amplifier A having positive feedback provided via resistors R5, R6 to its non-inverting input terminal. The junction between the capacitor C and the diode switch is connected to the inverting input terminal of amplifier A. The amplifier A changes its output alternately between two limiting states as the difference in magnitude of its two input signals tends to change sign and at other times rests in one or other of its steady states, Fig. 3. When the output voltage V 0  is at a positive limiting value this voltage is supplied to the non-inverting input of the amplifier A and also to the junction of diodes D1, D4. Assuming there is only a small voltage across C, diodes D1 and D3 will be biased off, D4 will conduct and the collector current from transistor VT2 will charge the capacitor C via diode D2, the voltage across C rising linearly to produce the rising portion of the triangular waveform, Fig. 2. When the difference between the rising voltage V applied to the inverting terminal and the voltage applied to the non-inverting terminal of the amplifier is reduced sufficiently, the gain of the amplifier will increase and a negative transient will be fed back via the feedback path of the amplifier to rapidly reverse the polarity of the output V 0  so that a negative bias appears at the junction of diodes D1, D4. Under these conditions D1 and D3 will conduct D2 and D4 will be biased off and the capacitor C will discharge through D3 and VT3 so that the voltage V c  will fall linearly until the difference between it and the negative bias applied to the non-inverting input is sufficient to cause the amplifier gain to rise and the resulting positive feedback to rapidly reverse the polarity of the output V 0  and the cycle is repeated. The control voltage V 1  controls the collector currents of transistors VT2, VT3 and hence the slopes of the triangular waveform VC and the frequency of the output voltage V 0 .

In the cathodic protection of the tanks of cargo ships by the provision therein of consumable anodes or anodes used with applied electric current, the anodes 16 which, for example, are of magnesium alloy, are cast around iron rods 12 so that the ends of the rods project to form means whereby the anodes are secured to and equally spaced apart on supporting ropes 10, 11, thus forming a ladder-like structure. The anode assembly or a group of such assemblies, is hung from a bar 21, the lower ends of the ropes 10, 11 being secured to a bar 22 and provided with tensioning devices 25 to hold the anodes at a preset distance from the tank surface to be protected, the anodes being electrically connected by a conductor which is connected to the tank structure. In a modification, the ropes 10, 11 are replaced by supports formed of separate metal links. The arrangement is such that the anode assembly can be easily removed from and replaced in the tank, for example, when consumed anodes are to be replaced or, when the anodes are not required in the tank, the assemblies can be withdrawn and folded or rolled up for storage.

Abstract: 522,628. Change-speed chain gearing. GARDINI, P., TROTTIER, G., and DECHANET, R. Nov. 17, 1938, Nos. 33469 and 33471. Convention dates, Nov. 20, 1937, and Aug. 25, 1938. [Class 80 (ii)] [Also in Group XXXI] In change-speed chain gearing for cycles &c. of the type in which the chain is selectively engaged with driven sprockets of different sizes, means are provided on the rear fork near the driven sprockets for supporting the chain in an inoperative or non-driving position, whereby the removal of the rear wheel is facilitated. The chain is shifted into a non-driving position on a fixed disc or drum 45, Figs. 1 and 2, provided with a flange 47 around part of its periphery ; or an idle sprocket may be employed instead of the fixed drum. When the chain is in this position, the rear wheel of the cycle may be readily removed by unscrewing a spindle 46, provided with a lever or wing-nut, from a bush 44 forming the inner cone of the hub bearing, a similar screwed spindle being provided on the other side of the wheel. Several modified arrangements for mounting the fixed chain-supporting disc and the screwed spindle 46 on the fork end are described, means being provided for ensuring correct centring of the wheel. The Specification as open to inspection under Sect. 91, comprises also the following subjectmatter. A support 1 secured to the cycle fork 3 is provided with a U-shaped member 4, in which are pivoted at 5, 6 links 7, 8, the other ends of which are pivoted at 9, 10 of a chainshifting fork 11, 12, thus forming a parallelogrammic linkage adapted to be actuated by a double Bowden control cable 15, Fig. 2, to move the chain laterally as indicated in dotted lines. The cable 15 is looped around, and fixed by a screw to, a roller secured to an operating lever, which moves over a dial and can be held by an eye or stop in an extreme position corresponding to the non-driving position of the driving-chain, the movement of the roller and lever being frictionally controlled under the action of a spring at the pivot. The outer part 12 of the chain-shifting fork is extended to form an angular arm 20, 20a, in which is mounted the spindle 21 of a chain-guiding roller 22, a chaintensioning lever 26 carrying a roller 27 being also journalled on the spindle 21. The end of the arm 20, 20a, carries a stud 28 on which is mounted the coil of a torsion spring 29, which is connected to the lever 26 by a link 30 so arranged that the chain receives equal tension in all positions of the change-speed device. The rollers 22, 27 are each formed of two flanged members soldered &c. together and enclosing a ball bearing between them, and may be provided with peripheral notches formed to fit the rollers of the chain and spaced apart at a distance corresponding to one half of the pitch of the chain. This subject-matter does not appear in the Specification as accepted.
