Title: Magnetic bubble propagation systems
IPC: G11C19/08
Filed: 1975-05-29
Abstract: 1503816 Magnetic storage arrangements MONSANTO CO 29 May 1975 [30 May 1974] 23368/75 Heading H3B In a magnetic bubble system in which an overlay pattern of ferromagnetic elements defining a bubble propagation path is such that bubble movement is effected by sequential in-plane magnetic field pulses oriented in a particular three phase vector pattern, the transfer of bubbles from one propagation path to another in a region common to both paths is effected by control of the  phase sequence of the vector pattern of the magnetic field pulses. Several different forms of elements arranged in overlay patterns are described, Figs. 2, 3, 4, 5, 6, 7 and 8 (not shown). Fig. 1A shows a typical such pattern formed by a plurality of so-called "dog leg" elements 14, and Fig. 2 shows a pattern formed by "alternate dog leg" elements 35. Two distinct propagation paths 10, 11, Fig. 1, are defined by such elements, magnetic bubbles being moved along one or other of these paths in response to an appropriate phase sequence and spatial position of in-plane magnetic field pulses represented by vectors 12 and 13. Transfer between a major loop and a minor loop is provided in the Fig. 10 arrangement, the major loop being formed of so called "crow feet" elements 124, while the minor loop comprises "duck step" elements 146, "crow foot" elements 126' and "chicken claw" elements 144. A common transfer region is formed by composite "crow feet" elements 134. Minor loop bubble propagation is effected by the vector system of field pulses 148, and major loop propagation by the vector system of field pulses 150, transfer of bubbles in the common transfer region being effected by stopping one in-plane field and starting the other. A transfer region using composite "crow feet" elements 152 arranged in a different manner is shown in Fig. 11, transfer being conditional on a bubble being in position 2 or b and the changeover of pulsed fields 160, 162 being effected at this time. This arrangement provides parallel transfer, serial transfer being obtainable when only one common leg 154 of the overlay pattern is provided, Fig. 12 (not shown). Other arrangements of "dog leg", "duck step" and "chicken claw" elements forming common transfer regions are described, Figs. 14 to 24 (not shown).

Title: Improvements relating to control apparatus for electric motors
Inventor: DOLAN HARRY
IPC: B66B1/12
Filed: 1951-10-12
Abstract: 715,701. Control of motors. ENGLISH ELECTRIC CO., Ltd. Oct. 10, 1952 [Oct. 12, 1951], No. 23810/51. Class 38(3) Control apparatus for an electric motor comprises a plurality of switch means associated with the sections of a speed controlling resistor for the motor and a pilot motor for operating the switch means in sequence at predetermined time intervals so as to cut out resistance from the motor circuit. wherein adjusting means are provided for varying one or more of the time intervals independently of the other time intervals. Movement of a manually operable speed controller closes contacts MC1 ... MC4 and starts up a motor driven timing device 10 which is' effective to momentarily connect the positive bus bar 11 alternately to timing bus bars 12. 13. With contacts MC1 ... MC4 closed, contactor RC1 is energized to cut out the first section of the speed control resistor at the moment bus-bar 13 is engaged. Operation of contactor RC1 closes self maintaining contacts RC1b, opens contact RC1a to disconnect the contactor from the timing bus-bar 13. closes contacts RC1d to prepare contactor RC2 for operation and closes contacts RC1c. Closure of these latter contacts energizes an eddy current brake coil 14 associated with an aluminium disc driven by the motor. in the device 10. Thus the time interval between operation of contactor RC1 and contactor RC2 is controlled by the adjustable resistor r1. When timing bus-bar 12 now becomes energized contactor RC2 operates to cut out the second section of the speed control resistor together with its self-maintaining and isolating contacts RC2b and RC2a. Simultaneously contacts RC2d close and contacts RC2c open thereby inserting adjustable resistor r2 in series with the brake coil and removing resistor rl therefrom. Thus the time interval between operation of contactors RC2 and RC3 is controlled by resistor r2. The operation of the remainder of the apparatus is similar, the timing device being de-energized after the last contactor has been operated, Resistors rl ... r4 comprise the adjusting means for individually varying the time intervals between the operation of the contactors RC1 ... RC4, whilst resistor RA forms an adjustment common to all the time intervals. In a further embodiment the contactors RC1 ... may be operated mechanically by a cam system. The invention may be applied to both A.C. and D.C. motors and the speed controlling resistor may be used for dynamic braking. Specification 715,700 is referred to.

Abstract: 316,893. Twin Coach Co., (Assignees of Fageol, F. R.). April 19, 1928, [Convention date]. Divided on 309,984. Drawings to Specification. Controlling-apparatus, arrangements of hand, foot, and transmission gear in conjunction with.- Comprises a road vehicle having a pair of selfcontained power units disposed substantially centrally between the front and rear axles and connected to individual driving wheels by gear means individual to each engine, wherein means are provided which enable either power unit to drive its associated wheel singly or both power units to drive their associated wheels simultaneously. The invention is described in Specification 309,984 as open to inspection under Sect. 91 (3) (a), and is shown more particularly in Figs. 1, 3, 4, 10, 14 - - 17, of the drawings accompanying that Specification. The throttles of the two internalcombustion engines which drive independent rear road wheels are separately controlled by two pedals situated close together so that the driver can operate them simultaneously with one foot or separately as desired. The friction clutches are simultaneously controlled by a single pedal, and the change-speed gears, when such are used, are normally controlled by a single hand-lever, but the selector mechanism of either gear can be disconnected from the hand-lever so that only the gear still connected to the hand-lever is operated thereby, the other being left in neutral and its power unit thus disconnected from the corresponding road wheel.

[Class 38 (ii).] In a valve inverter system in which frequency is determined by a synchronous machine driven from the A.C. side of the inverter, means are provided whereby the machine is kept running during the time interval when the system is rendered inoperative while a faulty section of the A.C. network is being cut out. In the arrangement shown, the system is divided into two parts comprising transformers T1, T2 and valve apparatus G1, G2 feeding A.C. networks NW1, NW2 each associated with a synchronous machine M1, M2. The two machines are mechanically coupled so that in the event of a fault arising on either network rendering it necessary for the corresponding circuit-breaker S1 or S2 on the D.C. side to be opened while the faulty section is being disconnected, the machine associated with that network will be maintained at synchronous speed by the other machine. Thus, after disconnection of the faulty section, the circuit-breaker on the D.C. side may be immediately reclosed to continue supply to the remainder of the network. The Specification as open to inspection under Sect. 91 comprises also modifications in which speed is maintained during the inoperative interval by providing the machine with a flywheel or by an auxiliary drive from some independent source. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in and relating to the hydrogenation of coal
IPC: C10G1/06
Filed: 1952-09-26
Abstract: <PICT:0727274/III/1> In the destructive hydrogenation of coal, the coal and the pasting oil are heated separately to such temperatures that on mixing the coal and oil the temperature of the mixture is at least 300 DEG  C.; the mixture is then destructively hydrogenated and the heavy oils are separated and recirculated as pasting oil. Operating in this manner, the percentage of coal in the mixture may be made as high as 65-75 per cent.  The pulverized coal is preheated to temperatures of 325-400 DEG  C. by suspending the coal in hot inert combustion gases and then separating the coal particles from the gas in a cyclone separator.  As shown, coal stored in a bin 10 is passed through a pulverizer 12 to mix with fuel gas fed through line 14 to cyclone separator 16.  The heated coal is mixed with recycle oil in paste mixer 20 and then fed by pump 26 to converter 30 supplied with hydrogen from furnace 32.  The hydrogenated products pass to hot separator 38 from which heavy oils and solids are removed to separator 42, from which the oil is recycled to the mixer 20. Vapour products pass to cold separator 46 from which condensate is removed to light oils still 52 and absorber tower plant 58, while gases, e.g. hydrogen, pass to the hydrogen recycle line 48.

Abstract: 434,997. Level-crossing signals. NAAMLOOZE VENNOOTSCHAP MACHINERIEEN-EN APPARATEN FABRIEKEN MEAF, 30, Croeselaan, Utrecht, Holland. Aug. 22, 1934, No. 24254. Convention date, Aug. 22, 1933. Addition to 426,870. [Class 105] The level - crossing signal arrangement shown in Fig. 2 of the parent Specification is arranged so that a leaving train causes the inner and outer rail lengths to be connected together. When an approaching train enters section A the relay 1 drops so that its open front contact 12a disconnects relay 2 (to prevent energization thereof) and its back contact 12b in conjunction with a contact 23b connects the section rail B to rail A ; thus the same conditions persist when the train is in section B. The back contact 11b of the relay 1 picks up a relay 3 over a back contact 42b of a relay 4 and a back contact 21b of the relay 2 ; the relay 3 is then stuck up over its contact 32a. The danger signal R is energized over a front contact 31a of the stick relay 3 which continues energized when the entrance sections A, B are vacated and the relay 1 is re-energized. When the train reaches the section rails G, E, H at the crossing the relay 2 is energized from its battery B2 over front contact 12a of relay 1. The front contact 21a of the relay 2 then picks up the relay 4 over the front contact 33a of the relay 3 ; the relay 4 then sticks over its own front 42a and the front contact 21a. The danger signal R continues to be energized, but now over the front contact 41a of the relay 4 since the relay 3 is de-energized by the opening of the back contact 42b. Contact 43a of relay 4 connects the rail E to the rails G, H so that the present conditions persist until the rails G, E, H are left, whereupon the relay 2 drops and so de-energizes the relay 4 to energize the clear signal W over the back contacts 31b, 41b of the relays 3, 4. The apparatus is now normal. When the leaving train reaches section D the relay 2 is energized over the front contact 12a of the relay 1 and sticks over its own contact 22a so that when the train enters section C and de-energizes the relay 1 the relay 2 continues to be energized, at first over its own front contact 22a and the axles still in section D, but later over the back contact 13b of the relay 1, its own front contact 23a, and the axles in section C ; it will be seen that at this later time the sections D, C are connected by the contacts 22a, 13b, 23a. The closure of the back contact 11b is now ineffective to pick up the relay 3 since the back contact 21b of the relay 2 is open and thus there is no effect on the clear signal W which remains energized over the normal circuit. When the leaving train vacates section C the complete apparatus returns to the normal state. The sections L, M, F of the return rail are insulated and are included in the return conductor of the relay 1 so that any damage to the rails will de-energize the relay.
