Abstract: 1,202,552. 552. Recording Fourier transforms. BRITISH AIRCRAFT CORP. Ltd. Aug.2, 1968 [Aug.2, 1967], No.35478/67. Heading G2J. [Also in Division H4] A method of recording the Fourier transform of an object 40 comprises focusing an image of the object in incoherent light at afocal plane 13, causing the surface 16 of a suitable deformable medium 12 to be locally distorted in a manner corresponding to the local intensity of light in the image, the surface being spaced from the focal plane, illuminating the distorted surface with coherent light S, and collecting coherent light reflected from the surface 16 away from the object in a manner to record in a suitable recording medium 50 and in coherent light the Fourier transform of the object. The image of the object 40 is focused through a glass substrate 10 on to a photo-conducting layer 13 carrying an integral grid structure 14 connected to an electric current. The deformable medium 12 (e.g. PVC) is formed on a second glass substrate 11 and is spaced from the photo-conducting layer by an air space of 10 to 100 microns. A D.C. or A.C. field is applied through both the photoconducting and deformable layer. Thus the surface 16 of medium 12 is locally deformed in a manner corresponding to the local intensity of the signal focused on layer 13. The recording medium 50 may be a photographic plate, other photographic emulsion surface layer or a photo-chromic crystal. In an alternative system the glass substrate 10 and photo-conducting layer are replaced by an electron gun directed at medium 12 and a TV camera is arranged to supply a video-signal to the gun to modify the surface 16 of medium 12 directly.

Title: Improvenments in or relating to gas cleaning apparatus
IPC: B01D46/04
Filed: 1962-09-18
Abstract: 1,019,735. Cleaning bag filters. AMERICAN AIR FILTER CO. Inc. Sept. 18, 1962 [Sept. 27, 1961], No. 35521/62. Heading BIT. Outward flow filter bags 23, e.g. of fibrous glass material capable of resisting temperatures as high as 550 F., are cleaned by reverse flow or the gas being filtered, the cleaning being further effected by so interrupting the subsequent resumed flow of the gas being filtered before the bags are fully inflated that the bags will reach their fully inflated position by virtue of their own inertia, thus producing fluttering of the bags. The bags are disposed in a housing 2 comprising a dirty gas inlet section 3, a bag section 4, a clean gas outlet section 5, a hopper section 6 and a damper section 7. The section 3 is divided into four separate compartments each having a dirty gas inlet 9 and a reverse gas flow outlet 11, and the section 5 has a clean gas outlet 10. The section 7 is provided with a damper 14 for each inlet 9 and a damper 16 for each outlet 11, the movement of the dampers being accomplished pneumatically under the control of an electrical circuit, Fig. 3 (not shown), which comprises switches operated by cam timers so that the pairs of dampers associated with the compartments of the section 3 are operated successively. Blowers (not shown) are provided to move the dirty gas through the inlets 9 and the bags 23 to the outlet 10 and reverse flow of clean gas through the bags 23 and the reverse gas flow outlets 11. During normal flow of dirty gas through each compartment of section 3 the inlet 9 and outlet 11 associated with the compartment are open and closed, respectively. When the bags 23 associated with the compartment have to be cleaned the electrical circuit operates the dampers 14 and 16 to close the inlet 9 and open the outlet 11 which collapses the bags. After a given time the position of the dampers 14 and 16 are returned to normal but before the bags inflate fully the damper 14 is again moved to close the inlet 9. The damper 14 is subsequently moved to again open the inlet 9 and normal cleaning of the dirty gas then proceeds. The hopper section 6 is provided with a pair of rotary valves 12, 13 which are timed to open and close in a preselected manner in accordance with the bag cleaning operations.

Title: A process for the production of polyolefins from unsaturated hydrocarbons
IPC: C08F10/14
Filed: 1962-09-20
Abstract: Olefin polymers are made by subjecting mono-ethylenically unsaturated hydrocarbons having 4 or more C atoms and which do not contain vinyl groups to an isomerizing treatment with organo-boron compounds and polymerizing the resultant mixtures containing 40 to 80% vinyl compounds, possibly with the addition of other alpha-olefins, in the presence of a catalyst comprising organometallic compounds of metals of Group I to III and compounds of metals of Group IVa to VIa, and VIII of the Mendel<\>geeff Periodic Table, removing the polymerizate from the polymerization zone continuously or intermittently, separating the polymer produced and returning the residual mixture into the isomerization stage.  The unsaturated hydrocarbons which are used in the isomerization step are generally obtained by the dimerization or inter-dimerization of olefins containing up to 7 carbon atoms, e.g. ethylene, propylene, or butylene.  In the example, 2-methylpentene-1, obtained by the dimerization of propylene, is isomerized with boron tri-propyl, and the products of isomerization after fractionating, polymerized with alpha-TiCl3 and tri-ethylaluminium.  The polymer recovered is purified by conventional techniques, e.g. addition of water, alcohol, acids or alkali.  The Specification includes a process, including a flow diagram, of a continuous method of effecting dimerization, isomerization, polymerization, and recovery.
