Title: Process for the separation of a wax-containing mixture
IPC: C10G73/06
Filed: 1965-12-22
Abstract: A wax-containing mixture which has been cooled to form wax crystals is separated in a primary hydrocyclonic zone into a primary underflow stream comprising at least a portion of the wax crystals and a primary overflow stream, the primary underflow stream is treated in at least one secondary hydrocyclonic zone, solvent being introduced into the (or the last) secondary hydrocyclonic zone, to yield a wax product, and/or the primary overflow stream is treated in at least one tertiary hydrocyclonic zone, to yield an oil or a lighter wax product.  Mixtures which may be thus treated include the waxy distillate or waxy residual oils, oily paraffin or oily microcrytalline waxes obtained from distillate and residual oils respectively, or a mixture of paraffin and microcrystalline waxes. Cooled waxy oil 5 is separated <PICT:1073809/C4-C5/1> in primary hydrocyclone 7 into a predominantly liquid overflow 9 and wax-containing underflow 11.  The halves of the Figure above and below 7 illustrate the subsequent de-waxing of the oil and de-oiling of the wax respectively.  De-oiling is carried out in three secondary hydrocyclones 15, 27, 31 and a separator 41 from which crude wax is obtained. De-waxing takes place in three tertiary hydrocyclones 55, 61, 65 and a separator 75 from which oil is withdrawn.  Arrowed lines indicate recycling &c.  The solvent is propane.  Other solvents are specified.

Title: Microprogrammed processor
IPC: G06F3/00
Filed: 1974-12-18
Abstract: 1496779 Peripheral controller HONEYWELL INFORMATION SYSTEMS Inc 18 Dec 1974 [18 Dec 1973] 54622/74 Heading G4A In a microprogrammed processor controlling peripheral devices a store includes "director" sequences of microinstructions which result in operation in a control byte appropriate to a peripheral device being serviced being stored in a register and "execution" sequences of microinstructions which effect a command relating to the peripheral 'device in accordance with the contents of the register. As described, mass storage devices 500, Fig. 1, e.g. tape or disc, communicate with a main memory 104 in a central processor 100 via the peripheral processor 300. The records on the storage device include a count field, key field and data field all or part of which may be written/read by an IO command. When I/O controller 101/6 receives an I/O instruction specifying that processor 300 is to execute a read operation on the count, key and data field of the record it transfers a number of command bytes to the processor 300 including a logical channel number byte specifying the channel to be involved, a command code byte specifying the type of operation, count byte specifying the number of bytes to be transferred to main storage and address bytes specifying the start address in main storage. The channel number byte and command code byte are stored in general purpose registers in the processor 300. The processor then executes a series of microinstructions which test the bits of the command code byte and branch to the appropriate "director" routine to store a director byte in one of the general purpose registers. The processor then enters the read execution routine and first performs a test on the state of the bits stored in an adapter parameter register to see whether the device calls for parallel or serial read. The appropriate routine is then effected with, for example, bit 1 of the director byte being examined if a read error occurs to determine whether it should be ignored or not.

[Also in Division G1] A sinusoidal constant amplitude variable frequency force applied to a body being tested (see Division G1) is obtained from an electromechanical vibrator unit. An axially vibratable probe 2, Fig. 3, is mounted on a resilient spider 29 so that vibrator coil 3 when energized by a sinusoidal constant amplitude variable frequency signal from a mixer, Fig. 1 (not shown), moves in the air gap between magnet poles 30, 31. In order to indicate when the pressure exerted on a body being tested falls outside preset limits three contacts 26, 27, 28 are provided. In the position shown when the probe 2 is not held against the body contacts 26, 27 touch and light a lamp, Fig. 2 (not shown). If the vibrator is held against the body with a force greater than is required contacts 27, 28 touch and a second lamp is energized. When the force exerted by the probe 2 is in the correct range both lamps are extinguished. In the vibrator unit of Fig. 6 the probe 2<SP>1</SP> is biased forward by spring 40 so that spider 29<SP>1</SP> is bent away from magnet 31<SP>1</SP> when no force is applied to the unit. When a static load is applied to the unit the spider assumes its mid-position as shown and oscillates thereabout allowing greater amplitude of movement than in the Fig. 3 arrangement.
