Title: Improvements in railway signalling systems
IPC: B61L29/28
Filed: 1963-05-10
Abstract: 1,002,619. Block signalling; level crossing control. FORGES ET ATELIERS DE CONSTRUCTIONS ELECTRIQUES DE JEUMONT. May 10, 1963 [May 11, 1962], No. 18585/63. Heading B7N. In an automatic block signalling system, a relay 24, controlling the operation of a level crossing N, is operated when a train occupies a signalling zone L which extends over part of two block signalling sections 1 and 2. The sections are supplied with pulsed current from transmitters E1, E2. When a train enters section 1, relay 14, which forms part of receiver R2 of the type described in Specification 852,386, releases but an auxiliary relay 9, normally supplied via secondary winding 8b of transformer 8, is maintained energized by operation of contact 13, relay 14, which alters the relay supply circuit to include secondary windings 8B and 8C. The voltage developed across these windings is sufficient to maintain relay 9 energized until the train reaches point C when release of the relay opens at contacts 15 the supply circuit to relay 24. This relay releases and in addition to operating a warning via contacts (not shown) to road vehicles approaching the crossing also releases auxiliary relay 20 at contact 23. The sensitivity of the circuit feeding relays 24 and 20 is increased by increasing the step-up ratio of transformer 18 at back contact 19 relay 20. When the train enters section 2, signal relay 7 is switched to danger via a relay associated with receiver R1, relays 14 and 9 pick up but relays 24 and 20 are maintained released by the absence of a signal at points c and d positioned beyond the level crossing. When the rear end of the train reaches point F the voltage applied to the primary of transformer 18 is sufficient to energize relay 24 which picks up and cancels the road warning signal.

Patent GB-404018-A (GB)
Title: Improvements in processes of and apparatus for treating solid materials with gases
IPC: F27B7/20
Filed: 1932-07-06
Abstract: In a process and apparatus for treating a layer of fine granular material of relatively high specific gravity, such as minerals, with a gas which is caused to pass through the layer, the material is charged in a layer on to a moving grate or sieve part of which serves to support the layer but from part of which it tends to fall, and the layer is held to the grate or sieve by setting up a sufficient difference of gas pressure on the two sides thereof.  The material is finally discharged from the grate or sieve by reducing or eliminating the pressure difference <PICT:0404018/III/1> <PICT:0404018/III/2> <PICT:0404018/III/3> <PICT:0404018/III/4> at the point of discharge. The treatment may be for the purposes of effecting chemical reactions, heat exchange, or the removal of solid matter from the gas.  Suitable granulation of the initial material may be effected by treatment with water, insufficient to form a slurry, in a crushing mill, grinding drum, or like mixing or pulverising apparatus, with subsequent drying if necessary.  In one arrangement, Figs. 1 and 2, the granular material is supplied through a shoot 4 to form a layer upon the outer surface of the perforated wall of a rotary cylindrical drum 1 mounted within a fixed casing 3 and the material is prevented from falling from the underside of the cylinder by the pressure of air supplied through an opening 5 in the casing 3 and extracted axially of the cylinder through a pipe 6.  At the point of discharge is provided a hood 7 connecting by a pipe 8 with the atmosphere or with a supply of compressed air.  In a modified arrangement the material forms a layer upon the inner surface of the perforated wall and the air is supplied to the inside of the drum.  Fig. 5 illustrates the use of the apparatus of Figs. 1 and 2 for preheating by means of the hot gases from a rotary kiln 12, granular material being fed to the kiln, the material being supplied to the drum 1 by a shoot 4 and worm conveyer 10 and held to the drum by the chimney draught, preferably increased, until it arrives beneath the hood 7 and falls into a shoot 13 delivering it into the kiln. Alternatively, the rotary grate may be built into the enlarged inlet end of the kiln, the material falling from the grate being transferred to the kiln by scoops.  In this case the grate preferably rotates more rapidly than the kiln.  Fig. 7 shows a modification of this arrangement in which the material is supplied by a shoot 4 and worm conveyer 10 to the inner surface of the perforated drum and on leaving the drum is delivered into the kiln by a shoot 13.

Patent GB-594084-A (GB)
Title: Improvements in or relating to cinematograph cameras
IPC: F41J5/10
Filed: 1944-10-09
Abstract: 594,084. Kinematograph cameras. DANEK, J., and TUDDENHAM J. Oct. 9, 1944, No. 19357. [Class 97 (i)] A kinematograph camera has a continuously rotating electric motor which drives the camera mechanism through a friction device, the camera mechanism being positively locked when not required to operate. As shown in Figs. 1 and 2, the motor 7 drives a control drum 10 through gearing and a friction disc held by a spring washer. The drum is allowed to revolve and the camera to operate when an electromagnet 14 is energized from an external circuit 8. When the circuit is broken, the armature 15 is pulled away from the magnet by the spring 16a and a projecting pin 18 rides on the surface of the drum until it enters a gap 17 in the wall of the drum. The projection 19 then rests on the surface of the drum and after one more revolution it engages the edge of the gap. To retain the armature, a spring blade 44 engages a step in the block 45. This blade is pulled aside again when the solenoid is next energized. The movement of the armature 15 as the pin 18 enters the gap in the drum brings a flag 9 into the camera field during the last exposure corresponding to the last revolution of the drum 10. The last exposed frame is marked accordingly. In a modification, Fig. 3, an arm 20 is spring urged, with reference to the drum 10, against a pin 21. After the arm 20 has engaged the projection 22 on the armature 15, the drum 10 completes one more revolution until the pin 21 strikes the other side of the arm 20. A projection 11 on the drum 10 operates the shutter blade 2 through levers 55, 56. An eccentric 46 operates an arm 48 which actuates the worm-driven counter device 49, 50 through a ratchet. The take-up spool 5 has a friction drive taken from the same gear train as the control drum 10. A film feed claw 13 is operated by a cam 12 carried on the same shaft as the drum 10. Specification 594,117 is referred to.
