Filed: 1975-01-17
Abstract: 1495792 Automatic control SNAMPROGETTI SpA 17 Jan 1975[1 Feb 1974] 2227/75 Heading G3N  The automatic production of drawings by a computer, or the production of drawing information for use by a computer, is effected by rotatably supporting a model of the plant and automatically surveying the model and supplying data to an electronic device producing a tape, or punched cards, which are fed into a computer producing a drawing and printed collateral information. As shown, a theodolite rangefinder 1 automatically surveys a model on a support 3. The co-ordinate data from a transmitter 2 together with collateral information from a keyboard 5 are transmitted to an electronic device 4. The device 4 serialises information fed to it, in accordance with a set program, and transmits it to a magnetic tape recorder, or punched card device 6. The processed information on the tape or cards is used by a computer 7 to control a plotter 8 and a printer 9 to prepare drawings and material lists.

[Also in Division B1] Methanol is synthesized by catalytically reacting a gas mixture consisting essentially of hydrogen and a carbon oxide at high temperature and pressure wherein the hot reaction gas mixture is cooled by heat exchange with a pressurized liquid which is thus heated to form high pressure vapour and wherein the methanol vapour in the cooled gas mixture is condensed and separated while the high pressure vapour is expanded with simultaneous recovery of usable generated power and then cooling the resulting low pressure vapour to a liquid which is pressurized prior to recycling said liquid for further heat exchange with the hot gas mixture. According to further embodiments of the invention the high pressure vapour may be superheated by heat exchange with a hot fluid, e.g. flue gas, prior to expansion of the said vapour and the cooled reaction gas mixture may be further cooled by heat exchange with an auxiliary coolant and additional methanol separated from the residual gas mixture prior to recycling the said mixture for further reaction. Specified pressurized liquids are ammonia, fluorohydrocarbon, methyl chloride, propane or butane suitably at a pressure of from 200-100 kg./sq. cm. and the preferred auxiliary coolant is water.

Abstract: 578,231. Automatic circuit-breakers. SHEPHERD, G. R. (Westinghouse Electric International Co.). Feb. 18, 1944, No. 3050. [Class 38 (v)] In a circuit-breaker which is immune from tripping by vibration, movement of the tripmagnet armature is obstructed by a loadcurrent carrying strip, which heats up and frees the armature with a time-delay on moderate overloads, but has a resilient connection with the armature which is overcome to produce instantaneous tripping. As applied to the three-pole breaker described in U.S.A. Specification 2,050,285, wherein a handle can open and close the circuit with a snap-action, the movable contact arms 23 are connected to a common frame 25, 33 pivoted at 61 and connected at 63 with a toggle 45, 47, which is pivoted at 65 to a normally-latched cradle 53 pivoted at 66 to the frame. The toggle-knee is connected by the dead-centre springs to a handle-lever 43 pivoted at 55 to the frame. When the cradle 53 is released on overload, the springs cause it to rotate clockwise and when pivot 65 passes the line of the springs, the toggle collapses and the contacts open. To reset, the lever 43 is moved anti-clockwise and a part 67 thereon restores cradle 53 to latched position, the lever being then moved back to reclose the contacts. The carrier is latched under the bridge of a U-shaped latch 79 rigid with a statically-balanced, common trip-bar 71 having a T-shaped projection 75 for each pole engageable by the spaced limbs of trip members 77 pivoting in slots in the trip bar. The members 77 are normally held, against spring-action 89, by adjustable parts 91 engaging projections 109 on the centrallypivoted armatures 101 of series coils 99. A leaf spring 111 on each armature has an adjusting screw 117 and projection 113 engaging the side of a series bimetal strip 95 serving as a latch and deflectable normal to the plane of armature-movement. The strip thus blocks the armature until an overload of predetermined value has passed for a given time, but on severe overload, the spring 111 is overcome at once to produce tripping. The cradle 53 in the resetting movement engages a reset pin 83 on latch 79, and the projections 75 in turn relatch the members 77 with the armatures. Specification 575,518 also is referred to.
