Title: Cooling and classification of particulate solids
IPC: B01J8/00
Filed: 1955-04-15
Abstract: <PICT:0768774/III/1> <PICT:0768774/III/2> <PICT:0768774/III/3> Hot coke particles from a coking zone of a hydrocarbon oil cracking process are fed through one or more lines 4, 5 and 11 into a vessel 1 and form a bed in the lower portion thereof. Water is injected into the bed through a nozzle 8 and the steam produced fluidizes the bed and passes upwardly through an elongated conduit 3 containing baffles 12, 13.  Fine coke particles are carried upwardly with the steam and the mixture leaves from a line 14, whilst cool relatively coarse particles are withdrawn through a line 6.  Additional fluidizing gas may be supplied through lines 9.  The velocity of the steam in the upper portion of the bed, and hence the entrainment of particles, is controlled by varying the upper level L2 of the bed relative the converging walls 2.  The steam and solids removed through line 14 may be returned to the coking system.  In Fig. 3 the classifier 59 is directly below a coker section 55 of a hydrocarbon oil conversion plant and hot coke particles pass directly over baffles 61 to the bottom of the classifier.  Alternatively the particles are fed through valve controlled lines 71, 72.  Water is supplied to the bottom of the coke bed through line 65 and steam may be supplied through a line 63.  Coarse particles are removed through a line 69 and the finer particles and steam are returned to the system.  In Fig. 2 a coking vessel 18 is supplied by a line 15 with hot particles from a fluid bed heater 21 fed with combustion gases through inlets 23, 24.  Oil is fed to the vessel 18 through nozzles 25, 27 and 29 and the coke bed in the vessel is fluidized by a gas or vapour flow. The resulting vapours pass through a cyclone system 35, are scrubbed in a section 37 and fractionated in a system 39.  Some coke particles are withdrawn through a line 45 and returned to the heater, and a further portion of the coke is withdrawn through a stripping section 55 supplied with stripping gas through a line 57 and fed downwardly into a quench-classifier 59.

Title: Improvements in or relating to polyphase self-starting electric synchronous motors
IPC: H02K19/14
Filed: 1943-07-12
Abstract: 575,681. Synchronous motors. GENERAL ELECTRIC CO., Ltd., and FRIEDLANDER, E. July 12, 1943, No. 11274. [Class 35] A polyphase, self-starting, synchronous motor with two primary windings.in series for starting and in parallel for synchronous operation, has a starting winding co-operating with each primary winding, these being formed by bars in salient pole faces or other non-uniform arrangement and the arrangement is such that relative phase displacements of the currents in the two starting windings is produced when changing the primary windings to parallel operation. In the form shown in Fig. 2, one starting winding consists of bars a', a<2>, a<3>, a<4> and the other bars b<1>-b<4> on cores displaced ninety electrical degrees during starting, but when synchronism is reached, primary windings d<1> d<2>, d<3> and e', e<2>, e<3> are parallel connected and the rotor bars are brought into alignment in the case of coaxial cores or into similar positions if the cores are on parallel shafts. Alternatively, one stator may be rocked relatively to the other. Instead of mechanical means, the phase displacement may be produced electrically, e.g. by subdividing one primary winding into two sections re-arranged from the connections shown in Fig. 5 for starting into those shown in Fig. 6 for synchronous operation, or by coupling a phase-shifting transformer or reactance in the circuit of one primary winding. Each primary winding may also be changed from delta to star.

The ring rail 4 of a twisting machine is operated by oscillating sprockets 8, 9 driven by the output shaft 3 of a reversing gear 2 through a worm gear 2a, 3a, the amplitude of movement being adjustable to control the rail travel by a gear arrangement 14 on shaft 3 and which operates cam discs 29a, 29b on radial arms 28a, 28b, the cams actuating the control member 2b of reverse gear 2. In the direction of rotation a<SP>1</SP> of shaft 3, Fig. 2, one-way clutches 18, 19 incorporated in pinions 15, 16 are respectively locked and overridden, so that gear 14 and cams 29a, 29b are rotated bodily with shaft 3. In the reverse direction of drive, Fig. 3 (not shown), the operation of clutches 18, 19 is reversed so that shaft 3 transmits a geared-up drive to pinions 24, 25 through pinions 23, 21, 22, thereby causing rotation of cams 29a, 29b about their spindles 27a, 27b as the latter revolve with shaft 3. Hence by fitting cam discs of different shape, the rotational position of shaft 3 at which operation of reversing control 2b occurs may be adjusted to vary the amplitudes of successive oscillations of shaft 3.
