Title: Improvements in door securing means
IPC: E05C5/02
Filed: 1955-11-15
Abstract: 792,777. Door fastenings. EVANS, O. (Ostroff, H. S.). Nov. 15, 1955, No. 32702/55. Class 44 A door operating means includes a latch bar 3 pivotally mounted on the inside of the door 4 for oscillation between a closed position, in which it engages a keeper 12 mounted on the door frame 13, and an open position in which it is disengaged from the keeper, means associated with the latch bar so that on rotation of the bar in one direction to a prescribed position, it may be moved axially and then rotated in the opposite direction to assume a locked position in which it is inhibited again bscillation to the open position and means for oscillating the latch bar from outside the door. The latch bar 3 made of round steel rod, is supported on the inside of the door 4 by means of a cylindrical bracket 5 provided with two apertures 6, 7. One aperture 6 provides a circular bearing for the bar so that the bar can be swung into or out of engagement with a keeper 12 and the other aperture 7 is a slot the ends of which limit the swinging movement of the bar 3. The end of the bar is bent to form a lever 8 by means of which the bar can be rotated, swung and moved axially. When the lever 8 is parallel to the surface of the door a radial key 9 on the bar 5 limits its axial movement but when the lever 8 is moved perpendicular to the door surface the key is brought into alignment with a notch 10 in the aperture 6 so that the end which engages the keeper can be moved through a hole 16 in the keeper. The keeper is formed of sheet metal and is bent. to define a recess 14 for retaining the end of the bar 3, the hole 16 being in the wall of the recess 14 which faces the bar 3. An inclined guide 15 is formed on the keeper to guide the bar into the recess. When the bar is not engaged with the hole 16 it can be swung to release it from the recess 14 from the outside of the door by means of a handle 26 secured to a shaft 22. The shaft 22 is journalled in a sleeve 23 integral with the bracket 5 and a plate 24 is secured to the inner end of the shaft, te plate having a bridge 25 projecting from it and straddling the bar 3. Thus when the handle 26 is turned the bar 3 is raised by the bridge 25. On the outside of the door the sleeve 23 and the shaft 22 have apertures 27 which' register when the handle is in its neutral position so that a padlock 29 can be inserted through the aperture 27 to immobilize the handle 26, Such immobilizing of the handle 26 does not prevent operation of the bar 3 from the inside of the door. Complete withdrawal of the bar 3 from the bracket 5 is prevented by means of a lug 18. The keeper 12 is provided with a hole 30 in which the padlock can be hung when not in use and the hole 30 is positioned so that it can take the place of the hole 16 when the device is used on a door of opposite hand.

Title: Improvements in Processes for the Manufacture of Sulphur
Inventor: SERVASIER ALFRED
IPC: C01B17/04
Filed: 1968-07-11
Abstract: 1,191,242. Sulphur. SOC. NATIONALE DES PETROLES D'AQUITAINE. 11 July, 1968, No. 33131/68. Heading C1A. Superheated steam is used to flush process units for the manufacture of S from a gaseous mixture containing H 2 S 1  as a precautionary measure when the gas supply is interrupted. A typical process unit for the production of S consists of a combustion furnace with a number of catalytic converters, between each pair of which is a condenser which condenses the S. The steam can be produced either in the combustion furnace or an external furnace, in the former case a valve is used to isolate the furnace during production of the steam. The steam may be at a pressure of between 2 to 30 bars at a temperature of between 300‹ to 500‹ C. before injection into a converter. The flushing process can be applied to Claus units.

Title: Method and arrangement for measuring small gas concentrations
IPC: G01N21/35
Filed: 1975-08-08
Abstract: 1523605 Photometric gas analysis LICENTIA PATENT VERWALTUNGS GmbH 8 Aug 1975 [9 Aug 1974] 33238/75 Heading G1A Gas analysis apparatus Fig. 1 comprises: a tunable infrared laser 1, and means 8 for controling the laser so as to produce light at a plurality of predetermined frequencies; a deflection device 2 for dividing the laser output into a measurement beam and a reference beam; means for directing the beams to at least one detector 5; means for locating a gas specimen 3 in the measurement beam; and means 7 for determining the relative transmissions of the gas at the respective frequencies.  The beam from the laser 1 e.g. a semi-conductor injection laser is selectively directed by an optical switch 2 into a measurement path containing the gas specimen 3, and a reference path, to illuminate a detector 5. Detector signals responsive to radiation received from respective measurement and reference beams are processed by an amplifier 6 and a store and computer 7, which controls the optical switch 2, and determines the laser emission frequency through a tuner 8 which may operate by pressure, or by a magnetic field, or by a temperature change due to a variation in the injected power.  Gas concentration is computed in accordance with one of two equations relating, at two and three frequencies respectively, the known absorption coefficients of the suspected gas, the length of the transmission path, and the logarithms of the measured transmission ratios. In the threefrequency equation the intervals between each frequency and the remaining frequencies also appear. In a second embodiment Fig. 2 (not shown) the optical switch is replaced by a beam-splitter (11) supplying a portion of the laser light directly to a second detector (5b) whose output is amplified (at 6b) and applied to a second input of the computer (7). In a third embodiment, Fig. 3, pulsed laser light is divided by a beam-splitter 11, a direct portion taking a short path to a detector 5, and a transmitted portion being retro-reflected in the specimen 3 to take a long path, and so to arrive at the detector 5 after the end of the direct pulse. A fourth embodiment using laser light of swept frequency Fig. 4 (not shown) is similar to the second embodiment, but has an added reference cell (12) in the common path between the laser (1) and the beam-splitter (11). The reference cell (12) is a cuvette containing a quantity of the pure gas at a pressure such that its absorption line is substantially narrower than the pressure-broadened line of the specimen gas (3). As the laser frequency sweeps through this line, the narrow dip due to absorption by the reference cell (12) serves as a marker to calibrate the frequencies of the reference and measurement beams arriving at their respective detectors (5b, 5a), in the event of a difference in the respective transit times along the two paths.
