Patent GB-662356-A (GB)
Title: Improvements in or relating to the production of acetic anhydride
Filed: 1949-03-01
Abstract: <PICT:0662356/IV (b)/1> Acetic anhydride is obtained by a continuous process which comprises pyrolysing acetone to form ketene, immediately quenching the ketene, unconverted acetone and fixed gases so formed to a temperature of 200-300 DEG  F. by jet mixing them with a mixture of acetic anhydride and acetic acid, whereby the ketene reacts with the acetic acid to produce acetic anhydride, adding acetic acid to the reaction products and using at least a portion of the resultant mixture of acetic acid and acetic anhydride as the quenching medium.  Referring to the drawing acetone is vaporized in vaporizer 2 and then passed through the preheater 4 which is preheated to 1150 DEG  F. and then to pyrolysis chamber 6 which may be a single tube or coil of copper or of an alloy such as stainless steel containing a large amount of chromium or of the alloy disclosed in Specification 655,101.  The pyrolysis temperature may be from 1150 DEG  to 1300 DEG  F. with a contact time of 0.3 to 0.5 seconds.  The effluent gases from the pyrolysis chamber are immediately quenched to a temperature not exceeding 300 DEG  F. in the venturi mixer 8 with a mixture of 75-10 per cent acetic acid and 25-90 per cent acetic anhydride, this quenching mixture being preferably drawn off from tower 10 through line 12.  The quenched mixture then passes by line 9 to tower 10 where it is contacted counter-currently with glacial acetic acid introduced through lines 11 and 31.  The top section of the tower 10 serves as a fractionation section to separate the acetone and acetic acid, the acetone leaves in the top gases whilst a mixture of acetic acid and acetic anhydride is removed from the bottom of the tower and after passing through cooler 13 is pumped to venturi 8 where it is mixed with the effluent vapours from the chamber 6.  Another portion of the bottoms from tower 10 is passed through line 16 to the mid-section of fractionator 17 where the acetic acid and acetic anhydride are separated, the former being recycled to tower 10 through line 28, condenser 29 and line 31 and the latter withdrawn through line 32.  Unconverted acetone, some acetic acid and fixed gases (largely methane, carbon monoxide and ethylene) are passed overhead from tower 10 through condenser 19 to separator 20, a portion of the acetone being returned to tower 10 through line 21 as reflux and the remainder returned as feed to the vaporizer 2.  Fixed gases containing a small amount of acetone are passed by line 24 to scrubber 25, where they are contacted countercurrently at low temperature with glacial acetic acid introduced through line 26.  The acetic acid enriched with acetone is then returned to the middle of tower 10.  Specification 627,810 is referred to.

Title: Improvements in or relating to devices for measuring height
IPC: G01C5/00
Filed: 1953-03-02
Abstract: 725,837. Measuring height. ETIENNE, C. March 2, 1953 [June 23, 1952], No. 5759/53. Class 97 (2). A device for measuring the height of an object, e.g. a tree, comprises telescoping cylindrical parts 1, 5 and 9 of which part 1 has a window 3 which may register with a similar window 6 in the part 5. This part carries diametrically a plane mirror 8 which, when the device is collapsed, abuts a plane mirror 12 in the part 9, both mirrors then being viewable through the windows 3, 6. Abutting flanges 7, 10 on the parts 5, 9 carry scales respectively indicating angles in degrees and minutes, the zeroes of these scales coinciding when the mirrors are coplanar. In use a mark is made on the object at the height at which the device is to be held and the observer at an arbitrary distance d from the object holds the device at this selected height and, with the mirrors co-planar, observes one vertical half of the object in mirror 8 and the other vertical half thereof in mirror 12. The parts 5, 9 are then relatively rotated until the upper end of the vertical half seen in mirror 12 coincides with the observed mark. The angle A between the mirrors is then noted on the scales on flanges 7, 11 and the height of the object is determined by adding the height of the observed mark to the value d tan 2A. In order to ensure that the device is held at the height of the mark on the object, a frame in the form of an isosceles triangle having its apex weighted and its base pivoted centrally on a pin 4 projecting from parts 1 may be used.

Abstract: 945,881. Polarising spectacles. H.HEIMBERGER. Feb. 18, 1960 [March 3, 1959], No. 5836/60. Heading G2J. [Also in Division B7] To prevent dazzle from oncoming unpolarised motor vehicle headlights, a polarising foil, polarising in a vertical direction is provided on or behind the windscreen of a motor vehicle and an analyser, polarising in a horizontal direction is provided between the polariser and the drivers'eyes and is preferably in the form of a pair of polarising spectacles, the polariser and the analyser being provided with individual coloration which need not be the same for the polariser and analyser. Referring to Fig. 1, each spectacle eyepiece comprises a horizontally polarising foil c of light green colour disposed between optically neutral synthetic plastic cover plates a,b. A doublyrefracting transparent foil d having its optical axis inclined to the horizontal at an angle of 45 degrees, is disposed between the upper half of the foil c and the plate b. In unpolarised light the eyepieces appear uniformally green whilst behind the vertically polarising polariser on the windscreen, they have a green-blue appearance in those sections not covered with the foils d. The dazzle from oncoming headlights is prevented when the driver looks through the bottom halves of the spectacles. By looking through the upper halves, the driver can see the vertically polarised light arriving from ahead. In the embodiment shown in Fig. 2, each spectacle eyepiece is divided into zones A, B, C, D, by vertical separating lines 1, 2 and 3. All of the zones are covered with horizontally polarising foil. The zone A is also covered with a double refracting foil ensuring free viewing therethrough. The zone B is horizontally polarised and by slightly turning the head to the right (i.e. in righthand traffic) this surface is caused to intercept light beams passing through the windscreen polariser, and thus prevent dazzle. The zone C is also horizontally polarised to intercept light from following vehicles reflected from the rear-view mirror which is covered with a vertically polarising foil. Finally the zone D is also covered with a double refracting foil for viewing lights of vehicles approaching from the left or turning-in.
