Title: Improvements in fog signalling apparatus for railways
IPC: B61L5/22
Filed: 1930-11-13
Abstract: 361,593. Detonator apparatus for railway signalling. FLETCHER, - B. P., 7, Bentley Road, Cambridge. Nov. 13, 1930, No. 34162. [Class 105.] A detonator apparatus comprises a detonator-carrying belt or chain 30 passing round two wheels or drums, one a large drum 2 on a fixed axis and the other a small wheel 3 which is moved away from and towards the track rail 1 to place a fresh detonator in position by reason of the drum 2 being moved in one direction and then prevented by a ratchet arrangement from return movement. The apparatus is operated by a sliding bar 12 inserted in the semaphore signal operating wire and having a pin 11 to engage a slot 10 in the end of a lever 7 which is mounted on the same spindle 4 as the drum 2 and carries at its other end the small wheel 3. The slot 10 is formed with lost motion sections 46, 47 so that when the semaphore signal is cleared the lever 7 is moved a definite amount and by reason of its spring-pressed plungers 17, 18 engaging ratchet teeth 19 on the drum 2 moves the latter forward. When the signal is returned to danger the lever 7 is returned but the drum 2 is prevented from corresponding return movement by spring-pressed plungers 23, 24 mounted on fixed bases 25, 26; 'the small wheel 3 therefore rolls on the chain 30 and the effect is to place a fresh detonator on the rail 1. The chain is engaged by projections or studs 39 on the drum 2. A ramp 41 with an inclined face is attached to the rail 1 so that any detonator which may have been bent at the stem is properly guided on to the rail. The detonators 32, Fig. 3, are formed with stems bent at right-angles to engage sockets 34, 35 carried at appropriate spacing on the links 31 of the chain. Dual detonators 32 may be provided on each stem.

Title: Device for examining and measuring the balance condition of rotors or other rotary bodies
IPC: G01M1/22
Filed: 1962-09-12
Abstract: 1,013,266. Measuring rotary unbalance. W. & T. AVERY Ltd. Sept. 12, 1962 [Sept. 21, 1961], No. 34778/62. Heading G1N. In a device for measuring the unbalance of rotary bodies, transducers are mounted on members situated at the rotor journals supporting the rotor and rotating with it, the members transmitting the forces at the bearings to the transducers. Support 5-8, which carry load cells 11-14 disposed against the rotar journal 9, are mounted on a carrier 4 and a spindle 3, which is rotatably supported on stand 1. The load cells thus give constant outputs indicative of the magnitude and angular position of unbalance without the use of phase sensitive devices. In a modification brackets carrying strain gauges bear against the rotor journal at two axially spaced planes so that unbalance of rotors having flexible shafts may be measured. Fig. 3 shows an automatic balancing arrangement in which the axis of rotation of the rotor is automatically adjusted by motor 32 through screw 33. A counter-balance weight on the end of the screw moves in the opposite direction to support 31. A circuit for use with this arrangement is described (Fig. 5 not shown). The load cells 12,14 are each connected in series with the input of a separate bridge circuit, the bridge outputs being differentially connected and the resultant output being applied to one winding of motor 32. The other motor winding is fed from the same source as the bridge circuits. In a modified automatic balancing arrangement (Fig. 4, not shown) a ring member is clamped to the rotor journal and carries two masses adjustable in directions at right angles to each other by individual motors to vary the centre of gravity of the rotor. Load cells carried by an outer ring bear against the ring member, the outer ring being rotatably mounted on the test stand to rotate with the rotor.
