Abstract: 262,767. British Thomson-Houston Co., Ltd., (Assignees of Blake, D. K.). Dec. 8, 1925, [Convention date]. Switching systems; systems depending on the use of transformers.-High voltage mains 1 are connected to a low-voltage network 4 by feeders 7 including circuit-breakers 5, transformer 3 and automatic circuit-breakers 6. Each feeder is associated with a relay 9 for tripping the circuitbreaker 5 on occurrence of reverse energy flow in the feeder from the network due to either a fault or to the magnetizing current of the transformer being drawn from the network due to circuit-breaker 5 being opened. The relay 9 has a voltage coil 10 and a current coil 11 connected across the secondary of an easily saturated current transformer 8 so that the coil is sensitive to small magnetizing currents and yet is not damaged by heavy fault currents. When the circuit-breaker 5 is reclosed, the current coil 11 serves to ascertain when there is equality of voltage and phase on opposite sides of the circuitbreaker 6 and thereupon to energize the closing coil 19. As applied to a polyphase system, there is a relay 9 provided for each phase, the " opening " contacts of the relays being connected in parallel so that a fault on any phase trips the circuit-breaker 6, and the " closing " contacts being in series so that all phases have to be correct as regards voltage and phase before the circuit-breaker is closed.

Patent GB-760194-A (GB)
Title: Upgrading of heavy hydrocarbon oils
IPC: C10G9/32
Filed: 1954-11-01
Abstract: <PICT:0760194/III/1> In a process of cracking heavy hydrocarbon oils wherein the oil is introduced into a fluidized bed of hot non-catalytic solid particles and the cracked vapours withdrawn from the cracking zone are fractionated to obtain naphtha, gas oil and other products, the heavy bottoms fraction withdrawn from the fractionator is recycled to a separate section of said fluidized bed or alternatively to another fluidized bed, and the pressure in the recycle cracking zone is maintained higher than that in the primary cracking zone in order to prevent vaporization of the recycle fraction before liquid-phase cracking can occur.  A vacuum residuum, preheated to about 500 DEG F., is sprayed through line 1 into vessel 10 which contains a bed of coke particles, at about 950 DEG F., maintained in a fluidized state by steam introduced through line 7. The coking is effected with a pressure of about 15 p.s.i.g. in the upper part of vessel 10.  The cracked vapours pass out of vessel 10 through cyclone 20, and are conveyed by line 2 to fractionator 80. Light gases, naphtha and gas oil are withdrawn from the fractionator through lines 13, 14 and 15 respectively.  The residual fraction, boiling above 1100 DEG F., withdrawn from the base of the fractionator, is passed through line 6 to the lower part 30 of vessel 10.  This secondary coking zone contains a bed of hot coke particles, fluidized by steam supplied through line 8.  Coke particles from the main bed of vessel 10 can circulate through section 30; but baffles 50 ensure that the solids-circulation between the two zones is not too great.  The secondary zone lies about 50 feet below the pseudoliquid level of the main fluidized bed, so that the pressure in the secondary zone will be about 30 p.s.i.g.  The cracked vapours formed in section 30 flow upwards through the main fluidized bed to cyclone 20.  The fluidized coke particles are maintained in a hot condition by heater 60.  Coke particles are withdrawn from vessel 10, and are transported by steam through standpipe 3 to heater 60, where partial combustion of the particles in the presence of fluidizing air is effected.  The fluidized bed of particles in heater 60 is thereby maintained at about 1100 DEG F.  Hot particles are withdrawn from the heater, and transferred via lines 4 to 24 to the main and secondary fluidized beds respectively in vessel 10.  The temperature in section 30 can be higher or lower than that existing in the main zone. Excess coke is withdrawn from the system as product through line 5. In a modification an entirely separate secondary coking zone is used; and the vapours therefrom are introduced into the upper part of the main zone so that they are not degraded by the main coking bed.

Abstract: 751,958. Viscosimeters. NATIONAL RESEARCH DEVELOPMENT CORPORATION. March 1, 1954 [Dec. 12, 1952], No. 31596/52. Class 106 (2). In a device for determining the viscosity of thixotropic and non-Newtonian liquids, a body, moving in the liquid, is acted on by some varying external force other than the reaction of the liquid, and its motion and the magnitude of the varying force are recorded against time. A base, Fig. 1, supports a platform 5 and a pillar 6, and a disc-shaped body 12 perforated with holes 13 is fixed to the end of a rod 11 which is suspended from the pillar by a helical spring 9. Attached to the rod 11 by an arm 20 is a stylus which co-operates with a drum 17 driven by a synchronous motor 16 so that as the body falls through the liquid under test, which is in a container 1 surrounded by a thermal jacket 2, a graph of the effective external force acting on the body against time is produced. In a second embodiment, Fig. 5, a stirrer 21 fixed to gears 23 is acted on by a varying external couple. The cord 26 is wound up by a handle 24 until a spring 29 is fully extended and the handle is then released. The stirrer then rotates under the decreasing torque produced by the spring. Simultaneously a stylus, attached by an arm 34 to a carrier 32 which is attached to the cord, co-operates with a drum 35 driven by a synchronous motor 37 to produce a graph as before.
