Title: Continuous process for the production of ethylene terephthalate  polyesters
IPC: B01J19/00
Filed: 1974-02-14
Abstract: 1441679 Automatic control of viscosity KANEBO Ltd 14 Feb 1974 [22 Feb 1973] 6855/74 Heading G3R In a continuous process for producing polyesters, a polymer-forming melt is passed through a series of polymerization vessels. The melt viscosity at the inlet and outlet of each vessel, except for a first vessel, is measured, and a control signal for adjusting the conditions in a vessel is formed in dependence upon differences between the viscosities at the inlet and outlet of the vessel and command values for the viscosity. If the calculated setting for the adjustment lies outside a predetermined range, the command value for the viscosity of melt material leaving the preceding vessel is automatically varied accordingly. As shown, a melt of bis-2-hydroxyethyl terephthalate is pumped through low-pressure polymerization vessels 1, 2, 3 to form ethylene terephthalate polyesters for spinning into filaments 24, 25. The polymerization rate is determined by the pressure (near vacuum) in the vessels 1, 2, 3 which is controlled by regulators 14, 15, 16 setting valves 11, 12, 13 in ethylene glycol extraction circuits. The regulators 14, 15, 16 are controlled by a computer 26 periodically receiving inputs from viscosity measuring devices 21, 22, 23 connected to the outputs of the vessels 1, 2, 3. In the case of vessel 3, the signal from viscosity meter 23 is compared with a predetermined value and the difference is used to form a control signal in a PID circuit. This signal is added to a further signal representing a viscosity error at the meter 22 at an earlier time determined by the computer 26 from flow data. The resulting signal is used as a set value for the pressure regulator, but is also compared with a predetermined range of values, and if the signal falls outside this range, the computer 26 calculates a further signal to modify the desired value setting for the viscosity of the melt material leaving the vessel 2. In the case of vessel 1, the input viscosity is not measured, and if the calculated set point for the pressure regulator 14 lies outside a given range, an audible or visual alarm is actuated. The computer 26 may be of analog, digital or hybrid type.

Title: Improvements in or relating to street lamp structures
IPC: F21V21/38
Filed: 1936-03-07
Abstract: 466,367. Winding and supporting lamps. KEITH & BLACKMAN CO., Ltd., J., and KEITH, G. March 7, 1936, No. 6887. [Classes 78 (iv) and 78 (v)] In street lamp structures of the type in which the lamp is suspended from a gallowsarm on a supporting column and is movable by lowering and hoisting-gear, the lamp is suspended from a carriage which is movable along an inclined track so disposed that the lamp is maintained clear of passing traffic during raising or lowering. The gallows-arm 2, Fig. 1, is supported by an inclined rail 5, the lower end of which is attached directly to the column 3 by a clamp 10. The lower end may, however, be supported by the outer end of a bracket arm attached to the column. The lamp 1 is suspended from a carriage 8 running on the track 5 by a rope 9 attached to a winch 4. This rope passes over fixed guide pulleys 15, 16 to a guide pulley 18 on the carriage 8 which directs it into a tube 19 carried by a casting 20 surmounting the lamp. After passing downwardly through this tube, the rope passes round a pair of pulleys 21, Fig. 7, mounted on the casting 20, and upwardly through a tube 22 to an anchorage 23 on the carriage. The lamp-shipping mechanism is similar to that described in Specification 399,259 and includes a labyrinth-presenting ring 26 mounted on the casting 20 for rotation about an axis parallel to the rail 5 and engageable with pins 27 projecting inwardly from a casing 28 attached to the bend 17 through which gas is supplied from the hollow arm 2. A slot 30, Fig. 7, in the casing 28 is engaged by a projection 29 on the casting 20 to prevent rotation of the latter while the ring 26 is co-operating with the pins 27 in the initial and final operative movements of the winch. In a modification the rail 5 is replaced by a wire rope tensioned between the arm 2 and one end of a cross-bar attached to the column. A similarly tensioned rope connects the other end of the cross-bar to the arm 2. These two ropes may be continuous, or the second rope may be dispensed with and the first rope attached directly to the column 3. In the case of an electric lamp, current supply conductors are led through the arm 2 and bend 17 and connected to terminal spring prongs in the casing 28. There is sliding co-operation between the prongs and a pair of conducting strips insulated from the casting 20 and connected to the lamp.
