Title: Process for producing peptides
IPC: B01J19/10
Filed: 1974-03-06
Abstract: 1423961 Synthesis of peptides UNIVERSITY OF OSAKA JAPANESE MINISTRY OF EDUCATION 6 March 1974 [7 March 1973] 10128/74 Heading C3H Peptides are produced by a process which comprises reacting an amino-acid or a peptide with an amino-acid or peptide, the latter being bound to a resin, in the solid phase, in the presence of ultrasonic waves, the preferred frequencies of said waves being 78-22 kc./sec. The method involves blocking the terminal amino-acid group of the amino-acid or peptide by conventional reagents (t-butyloxycarbazide is preferred) and reacting the N-blocked derivative with a resin (e.g. a chloromethylated copolymer of styrene/divinylbenzene). The resulting amino-acid resin is swollen, washed and the N-terminal blocking group removed, all steps being performed by conventional reagents. Excess blocking agent is removed by washing and the resin neutralized with a suitable reagent. The resulting amino-acid resin or peptide resin is condensed with another amino-acid or peptide, which has an N-blocked amino group in the presence of a condensing agent (dicyclohexylcarbodiimide is preferred). The blocking agent is removed and the cycle repeated to build up the required peptide bound to resin. On completion of all steps, the peptide is removed from the resin by contacting the product with a cleaving agent. The use of ultrasonic waves is not limited to the condensation reaction but may also be used in any of the pre-treatment and after-treatment steps. Examples relate to the preparation of the nonapeptides: H.Arg - Pro - Pro - Gly - Phe- Set - Pro - Phe - Arg.OH (bradykinin), H.Arg- Gly-Phe-Phe-Tyr-Thr-Pro-Lys-Ala.OH. The bradykinin shows the same specific activity on guinea pig ileum muscle as that of authentic bradykinin.

Filed: 1965-03-10
Abstract: 1,091,933. Backwashing of filters for liquids. SWINNEY BROS Ltd. March 10, 1965, No. 10152/65. Heading B1D. A filter comprises a plurality of filter elements disposed exteriorly of a stationary hollow supporting member, a rotatable backwash pipe disposed axially of the member, ducts in the pipe arranged to register with apertures in the member and leading to the filter elements, and means for intermittently rotating the backwash pipe so that the ducts are brought into registration in turn with the apertures and are caused to dwell to permit the backwashing of the filter elements in sequence. As shown, unfiltered liquid enters, at 2, the region between a stationary hollow supporting member 3 and a rotatable backwash pipe 13. The liquid passes outwards through ports 11 into annular filter element supports 4 and then up through apertures 7 therein, above which apertures filter elements 8 are fixed. Filtrate passes upwards and outwards to the region between member 3 and outer body 1 and is discharged at 2A. At any one time, two backwash ducts 14 secured to pipe 13 provide communication between a port 11 and pipe 13, enabling filtrate to flow downwards through an element to clean it; liquid and residue escape, or are withdrawn, at 16. Each ported region of each support 4 is separated from adjacent regions by radial partitions; and the lands between the ports in member 3 are slightly wider than the ports. In addition to the two ducts 14 shown, two further ones (not visible) are provided, arranged to cooperate with the second and fourth assembly (reading downwards) of filter elements, but so disposed that in the position of pipe 13 shown they are aligned with lands between ports. The pipe 13 is rotated intermittently by a motor 15 through, e.g. a Geneva wheel movement. In a modification, the filter elements are vertical and located directly on the outside of member 3, and each duct 14 communicates with only half an element at a time.

Title: Improvements in optical systems for photography or kinematography particularly in colour
IPC: G02B27/14
Filed: 1932-04-12
Abstract: 404,307. Colour photography. HILLMANN, A. G., and COLOURGRAVURE, Ltd., Victoria House, Vernon Place, Southampton Row, London. April 12, 1932, Nos. 10489/32 and 10170/33. [Class 97 (i).] An optical light-dividing system for obtaining multiple images simultaneously for colour photography or kinematography comprises a non- refracting reflector device perforated with multiple holes which diminish in size through the reflector thickness towards the reflecting plane or planes, the non-reflecting walls of the holes having portions so inclined to the optical axis towards the margins of the surface receiving light transmitted through the holes as to facilitate the passage of light to the said margins, and also having portions which partially obstruct the passage of light to the central part of the said surface, so as to produce even illumination of the image obtained by transmitted light. The Figs. show a pair of reflectors 1, 2 arranged in the form of a V in rear of the objective 4 to produce two images by reflected light and one image by transmitted light. The reflectors are made of polished steel &c. and are provided with medial groups of perforations 7, 8 and with marginal groups 9, 10 all having their axes parallel to the optical axis of the objective, and also with groups 11, 12 having their axes inclined to the horizontal plane containing the optical axes. The axes of all the holes 11 or 12 in a given reflector above the transverse centre line C, D are inclined downwards substantially in parallelism, and those of the holes below the centre line are inclined upwards substantially in parallelism towards the front of the system so that the axes of all the holes intersect the said horizontal plane in front of the system. All the apertures are expanded towards the rear of the thickness of the reflectors, to facilitate the passage of light to the marginal portions of the direct image. To obtain more even illumination the diameters of the holes in any given reflector increase as their distance from the objective increases. To accommodate for the different filter factors for the two reflected images, the perforations in one reflector may be made smaller than those in the other, leaving a larger reflecting area. The reflectors are provided with interengaging tongues 13 and are mounted on supports 32, 33 in such a way that they can be adjusted as required in relation to the objective. An arrangement for two colour photography is also described, comprising a single perforated reflector and a plane mirror receiving the reflected rays and directing them parallel to the transmitted rays.
