Abstract: A data communication network for connecting inductive loop sensors comprises a feeder controller 1, one or more nodes 3 each node connected to an inductive loop sensor. Cable 108 allows for a duplex or bi-directional data circuit to be established with either the controller or with other nodes in the network. Each node comprises a transceiver 105 to connect to the cable/data circuit. Each node is also equipped with an encoder 101 and decoder 10, 102 for transmitting and receiving data to and from the data circuit. Communications to each node may comprise a control data in line 6, a control data out line 7, sensor data in line 9 and sensor data out line 8. In one embodiment one or more of the cables maybe replaced by a wireless communication path using a hidden or concealed antenna. In both embodiments the controller may issue control commands to the sensors and receive sensor information from the sensor assemblies. The node may also act as a repeater through the use of a forward amplifier 14 and a return amplifier 12.

Title: Improvements in or relating to the production of methanol and acetic acid from mixtures obtained by the hydrolysis of methyl acetate
Inventor: ANSELM HANS
IPC: C07C51/09
Filed: 1956-03-29
Abstract: Methanol and acetic acid are produced from a mixture obtained by the hydrolysis of methyl acetate in the presence of water and an acid catalyst, advantageously when the hydrolysis is over more than 50% complete, by passing the mixture continuously at approximately its boiling-point to the feed plate of a rectifying tower, the plate being maintained at a temperature below the boiling point of water; taking off from the tower above the feed plate alcohol which is surplus to the amount required to form an azeotrope with methyl acetate; extracting methyl alcohol from the binary mixture of methyl alcohol and methyl acetate obtained as head distillate by means of a highly concentrated aqueous solution of an organic or inorganic salt, which does not separate in the extraction and in which the ester is of low solubility and the alcohol of high solubility; distilling off the alcohol from the salt solution; passing the methyl acetate back to the hydrolysis stage; and recovering the acetic acid e.g. by solvent extraction, from the aqueous solution produced in the still body of the rectifying tower.  In a modification of the process, methyl alcohol and unhydrolysed methyl acetate are distilled off together from the rectifying tower and are separated in a second tower into binary mixture and methanol.  Suitable salts for use in the extraction are, for example, potassium formate, potassium acetate, sodium propionate, sodium chlorate, sodium chloride, sodium lactate and potassium phenolate or a mixture of such salts.
