Title: Circuit for light signals in railway equipment
IPC: B61L5/18
Filed: 1963-03-26
Abstract: 1,023,865. Automatic alarm systems. SOC. TECHNIQUE POUR L'INDUSTRIE NOUVELLE S.A. " STIN ". March 26, 1963 [April 13, 1962], No. 11860/63. Heading G4N. [Also in Division B7] In a light signalling arrangement for railways in which each aspect is signalled by a combination of at least two series connected lamps, e.g. lamps L1, L2, Fig. 1, the voltage across each lamp is maintained by checking devices P1, P2 connected to the lamps either by conductors P1, P2, M or by a common conductor and the lamp current connections, Fig. 2 (not shown). The voltage applied to each checking device energizes a relay with a contact, P11 or P21, in the circuit of a supervisory relay PR, Fig. 1a which on release disconnects the supply to the lamps and energizes an alarm circuit at contacts PR1 and PR3 respectively. After fault correction auxiliary relay Hi is released by operation of button T1 and energizes relay PR at its contact Hil; pick up of relay PR restores the lamp supply and on subsequent pick up of the checking device relays, relay Hi is again energized via contacts PR2, P12, P22 and relay PR is held energized via contacts P11 and P21.

Filed: 1943-07-28
Abstract: <PICT:0564565/IV/1> The endless impression blanket 11 of a textile printing - machine is cleaned in two stages between which a sheet of colour solvent is maintained on the blanket.  The blanket 11 passes from the impression cylinder 10 round a metal roller 13 on which colour is offset and removed by a scraper assisted by a colour solvent spray.  The blanket is then scrubbed by a rotary brush 18 which is cleaned by running in a solvent bath.  Between the bight of the brush 18 and a co-operating roller 14, solvent is sprayed on to the blanket which is thereby flooded with solvent which remains on the blanket as a sheet as it passes over a support 24 to the second stage of the cleaning.  The support 24 is shaped as shown in Fig. 7 to maintain the liquid on the blanket.  After leaving the support 24, the blanket passes downwards and around a roller 35 with which co - operate spring - pressed rubber - covered squeezing roller 38, a solvent spray 40, squeeze roller 42 and felt-covered blotting roller 20.  The blanket then passes through a drying apparatus 44 to the impression cylinder 10. Specification 23642/96, [Class 42], is referred to. <PICT:0564565/IV/2>
