Title: Gas blast type electric circuit interrupters
IPC: H01H33/56
Filed: 1962-10-05
Abstract: 971,280. Gas-blast circuit-breakers; automatic circuit-breakers; pressure actuation of switches. WESTINGHOUSE ELECTRIC CORPORATION. Oct. 5, 1962 [Oct. 12, 1961], No. 37690/62. Headings H2B and H2K. A gas-blast circuit interrupter having separable contacts 5, 6 in a casing 3 filled with arcextinguishing gas, such as the interrupter of Specification 904,160, is provided with operating mechanism including a trip coil 47, a "closing"  coil 37, a relay X for energizing the closing coil, and a switch 70 responsive to pressure in the casing and effective on low pressure to prevent the energizing of the relay X and the closing of the interrupter. The closing coil 37 may be the operating solenoid of the interrupter, but in the arrangement shown is the operating coil of a valve 34 controlling the admission of compressed air to an operating cylinder 31. Under normal conditions, the operation of a tripping switch CST causes the energization of the coil 47 to release a latch 46 so permitting the contacts 5, 6 to open under the bias of a spring 45. The interrupter is reclosed on the operation of a switch CSC which causes the energization of the relay X via contacts 101, LPC, 61 and 77, with the resulting energization of the coil 37, operation of the valve 34, and the closure of the interrupter contacts 5, 6. An " antipumping " relay Y is provided. Should the pressure in the casing 3 fall to a first predetermined value, a micro-switch unit 72 of the pressure-responsive switch 70 opens its contact 73, 77 to interrupt the circuit for the relay X to prevent a closing operation and closes contacts 73, 79 to complete an alarm circuit. In the event of a further fall in pressure, a second micro-switch unit 71 of the pressure-responsive switch 70 opens its contacts 73, 76 to interrupt the tripping circuit from the switch CST to prevent tripping. If, however, automatic tripping on loss of pressure is desired, a switch 98 is closed so that the trip coil 47 is energized when the unit 71 closes contacts 73, 78. Fig. 3 (not shown) illustrates a modified arrangement in which an alarm is given on the operation of the switch unit 72 and the switch unit 71 controls an additional relay which opens both tripping and closing circuits. In a further arrangement, Fig. 4 (not shown), the pressure-responsive switch has one micro-switch unit only. The pressure-responsive switch 70, Fig. 2, includes a diaphragm (not shown) which acts through a plunger 74 on a pivoted actuating plate 87 which is biased against the plunger by a spring 89, a spring adjustment 90 being provided.

In the form shown in Fig. 1, return air is entrained through inlets B<1>, B3 controlled by louvres 7, 9 so that one inlet is opened as the other is closed. Fresh air may be entrained through inlets B, B<2> so controlled by louvres 6, 8 that they open and close together thus effecting a control of the volume of fresh air admitted, the proportion passing through the heat exchanger being controlled by a damper 13. The air is admitted to the room from an outlet 3 at the upper part of the duct. In modified forms, the additional fresh air inlets are omitted and' the nozzles 2 are arranged below the return air inlets. In the form shown in Fig. 5, fresh air is supplied to a duct 15 and is ejected into the main duct through a nozzle formed by pivoted flaps 16, 17. The proportions of entrained air passing through the heat exchanger and byepass are controlled by a single damper 18. In another modification, Fig. 10, fresh air is entrained through an inlet B5 and return air through an inlet B<6>. The heat exchanger 4 extends across part of the main duct, a partition 26 forming a byepass 27 controlled by a damper 28. In a further modification, Fig. 12, two heat exchangers 4, 41 adapted respectively to heat and cool the entrained air are positioned obliquely across the main duct, a damper 28 hingedly suspended from the top of the lower exchanger serving to control the proportions of entrained air passing through each exchanger. Only one exchanger is in operation at any given time, the other forming a byepass. Air is admitted at the base of the casing through inlets B<5>, B<6> and filters 30 and may be humidified by means of a water tank 31. In a slightly modified form the upper heat exchanger is omitted.

Abstract: 1517975 Petroleum coke production MARUZEN PETROCHEMICAL CO Ltd 16 Sept 1975 [26 Sept 1974] 38066/75 Heading C5E A process for the production of petroleum coke from a low sulphur content feedstock comprises subjecting the feedstock to a heat treatment to remove non-crystalline substances as pitch or coke and thereafter injecting the feedstock downwardly into a coking chamber 1 through a nozzle 11, heating of the feedstock being effected by means of a heating medium circulated through a jacket 4; gaseous hydrocarbons produced during coking being discharged through line 14 and, when the accumulated coke fills the chamber, injection of feedstock being discontinued and a purging gas being introduced through line 12 to expel any remaining oil from the chamber through line 14, the coke produced being then withdrawn through outlets 2, 3. Clogging of the outlet of the purging gas line 12 during coking is prevented by allowing a slow stream of heated gas to flow into the chamber throughout the coking process. The initial heat treatment may take the form of flash distillation, the condensed oil from the flash distillate being used as feedstock for the coker. Alternatively, the non-crystalline compounds may be removed by delayed coking of the feedstock, the distillate from the delayed coking step being used as feedstock. Separation of the non-crystalline compounds may be aided by the addition of 0À5-10% by weight of a hydroxide and/or a carbonate of an alkali or alkaline earth metal.

Abstract: 1303927 Measuring fluorescence photoelectrically LABORATORY DATA CONTROL Inc 16 Aug 1971 [28 Sept 1970] 38285/71 Heading G1A In a differential fluorimeter including a radiation source and a photo-cell arrangement 70 for receiving fluorescent radiation from reference and sample materials, e.g. liquids flowing in the tubes 52 and 56, a light pipe 42 having a longitudinal dividing member 44 divides the incident beam into reference and sample beams. Fig.6 shows an exploded view of the apparatus, which may be used to monitor the output from a liquid chromatograph. Radiation from a low pressure, hot cathode Hg lamp with a phosphor coating 28, Fig.2, (not shown), passes through a UV filter (22) and fixed aperture (20) before being divided into the two beams. The fluorescent radiation from the sample and reference liquids passes through a UV blocking filter 68 before incidence upon respective photo-resistors 70a, 70b. These photo-cells form two arms of a bridge Fig.7, (not shown) whose output is supplied to a recorder. The mercury lamp is viewed by a third photo-resistor (82) included in a feedback path to the bridge power supply. In this way the bridge voltage is changed to compensate for any variations in source output. The light path also includes a movable shutter blade 32 containing a small aperture 34, for use in restricting the incident beam to strongly fluorescing liquids, and a weakly fluorescent screen 38, used for initially setting the zero on the recorder. Two thumb-screws 60, 62, carrying fluorescent beads at their ends, are movable into the sample and reference beams for balancing.

Abstract: 1,035,056. Fluid-pressure brakes. MIDLAND-ROSS CORPORATION. Sept. 30, 1963 [Oct. 9, 1962], No. 38378/63. Heading F2F. [Also in Division G3] In a power-assisted braking system a brakeactuating hydraulic master cylinder 17 is carried by the actuating cylinder 11 containing a power-actuated piston 12, a valve 13 being carried by the latter piston, and a manual control unit comprising a manually operated member 47, sliding in a sleeve 33 screwed into the cover 31 of the cylinder 11, and having a seating 73 co-operating with the valve 13 so that the retracted position of the manually operated member is adjustable relatively to the housing by means of rotation of the sleeve 33 from the outside of the brake mechanism to adjust the position of the hydraulic piston 18 in its retracted position with respect to a compensating port 19 formed in the side of the hydraulic master cylinder. The lower part of the housing 11 of the power piston is adapted to act as an hydraulic reservoir the compensating port 19 communicating between the hydraulic cylinder and this reservoir. In operation, effort applied to the pedal mechanism 48 is transmitted through the push rod 47 to a control member 14 to move the latter downwardly relative to the sleeve 33. Initial movement causes the exhaust valve seat 73 to move downwardly and engage the exhaust valve element 71 forming part of the valve 13 carried by the power-actuated piston 12 without disturbing the position of the supply valve element 66 closed on its seat 68 to isolate the fluid pressure chamber 52 from the atmosphere in the chamber 46 of the control member 14. Subsequent downward movement of the push rod 14 is transmitted to the valve mechanism 13 but not to the power piston 12 and is effective to actuate the valve mechanism so that the exhaust valve element 71 is moved downwardly relative to the stationary piston 12 and moves the supply valve element 66 from its seat 68 to permit compressed air under pressure from the chamber 62 to pass through the bore 69 into the chamber 52 above the piston 12. Since atmospheric pressure exists below the piston 12 the resulting pressure differential causes downward movement of the piston 12 and the rod 61 to actuate the piston 18 of the master cylinder 13 and apply the brakes 29.

Filed: 1966-08-30
Abstract: 1,135,254. Improved ammonia synthesis. ESSO RESEARCH & ENG. CO. 30 Aug., 1966, No. 38709/66. Heading C1A. Ammonia is produced by contacting a stream of nitrogen and hydrogen gas with an ammonia synthesis catalyst at ammonia synthesis conditions of temperature and pressure, forming ammonia, and thereafter complexing the product NH 3  with a metal halide to form a reversible complex, thereby driving the synthesis reaction on to form more product NH 3 . In one embodiment the N 2  and the H 2  may flow upwards through the catalyst and the molten metal halide flows downwardly in countercurrent, so forming a reversible complex and reducing the partial pressure of product NH 3  in the gas stream. Alternatively the N 2  and H 2  may flow upwards through a reaction zone (102) and the resulting stream of H 2 , N 2  and NH 3  passes up through a sorption zone (103) in countercurrent to molten metal halide. This may be repeated, as in Fig. 3, for a series of reaction zones (104, 106) and sorption zones (105, 107) until the hydrogen is substantially depleted. Descending complex and metal halide by-pass the catalyst zones via outlets (112, 115). The molten complex is recovered (via 118) and heated (121) to decompose it into NH 3  (122) and metal halide, the latter being recycled (123, 124, 108). The complex may also be decomposed by reducing the pressure on it. The metal halide may be a halide of Zn, Mn, Fe, Co, Ni or Mg. Preferred halides are ZnCl 2 , ZnBr 2 , MgBr 2  and MgI 2 .
