Abstract: 1,015,376. Optical apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. May 8 1964 [May 20, 1963], No. 19346/64. Heading G2J. [Also in Division H4]. A device for deflecting a light beam comprises a composite structure 20 of two optically refractive materials 22. 24, such as potassium dihydrogen phosphate, potassium dideuterium phosphate, ammonium dihydrogen phosphate or barium titanate, which have their refractive indexes variable under the influence of an electric field, an arrangement for directing light on to the boundary 26 between the two materials 22,24 and a pair of electrodes 28, 29 which may be platinum or gold coatings for applying the electric field to deflect the beam. As shown, light from a laser 10, or other monochromatic light source is collimated at 12, plane polarized at 14 and passed through an aperture 18 in a plate 16 to enter the crystal 22 through face 21. When no voltage is applied to electrodes 28, 29, the beam passes as shown by the dotted line undeviated across boundary 26, is reflected a number of times by reflective coatings 30 32 and emerges through face 33 of crystal 24. When a potential is applied to electrodes 28, 29 such as by source 36 and control means 38, the beam is deflected by a small amount ## each time it crosses boundary 26. Since the beam may obtain components of elliptically polarized light, in its multiple reflective path, a polarizer 35, aligned with polarizer 14, is placed in the putput path.

For example, the metal carbonate, bicarbonate or sesquicarbonate is precipitated in precipitator 4, wherein is an atmosphere of CO 2 , is filtered and the precipitate is washed in filter 6. The precipitate and washings are passed back to 4. Liquors are drawn from an unagitated zone of 4 to evaporator 11 where NH 3  and CO 2  are volatilized and condensed in 13 before passing back to 4. Residual solution is drawn from 11 to crystallizer 16 where water is evaporated at 40‹ C. through 18. From an unagitated zone of 16 liquors are passed to 4, while a slurry of ammonium perchlorate is passed to filter 20. The solid is washed and the filtrate and washings passed back to 16. Alternatively the metal perchlorate feed may be added to filtrate and wash liquors from 20 and added to 16. The CO 2  pressure may be from less than one atmosphere to greater than 20 atmospheres and the temperature may be from 10‹ C. to 110‹ C.

Abstract: 1,050,302. Diamidines. O. DANN. Feb. 19, 1965 [Feb. 19, 1964], No. 7312/66. Heading C2C. Novel compounds of the Formula I and their acid addition salts are prepared by reacting a di-imino-ether of the Formula III, where Hal represents a halogen atom and Alk represents a methyl of ethyl group, with dry ammonia gas in an anhydrous solvent, or by reacting a compound of the Formula II with an ammonium salt at an elevated temperature and, if desired, converting the products into their acid addition salts Di-imino-ethers of the Formula III may be prepared by reacting a compound of the Formula II with a dry hydrogen halide gas in the presence of an anhydrous alcohol Alk.OH and an anhydrous solvent. Di-cyano compounds of the Formula II may be prepared by cyclizing a tolyl-methyl-phenacyl sulphide to give a 2-tolyl-methyl-thionaphthene which can be halogenation in the methyl groups and the resultant halomethyl compounds converted into aldehydes, converting the aldehydes into their oximes followed by dehydration. 6-Cyano- and 5-cyano-2-(3<SP>1</SP>-cyanophenyl)thionaphthene may be prepared by conversion of 6- and 5-formyl-2-(3<SP>1</SP>-bromophenyl)thionaphthene into their mono-oximes followed by dehydration to give the monocyano-derivatives and subsequently exchanging the bromine atoms for cyano groups in known manner. Therapeutic compositions, with trypanocidal activity, in the form of solutions and ampoules for parenteral administration, comprise compounds of the Formula I and their non-toxic salts together with a pharmaceutical carrier.

Abstract: 1,052,110. Building frameworks; doors; glazing; door hinges. A. G. BOS. Aug. 26, 1964 [Aug. 26, 1963], No. 34971/64. Headings E1J, E1R, E1W and E2F. A building structure comprises hollow polygonal sections 1 provided along at least one side with a single trapezium shaped groove 4 slidably engaged by at least one tenon 14' rigid with co-operating part or parts of the structure. A groove may be provided in each of three of four walls of the section. Hollow vertical and transverse sections may be connected together by a connecting member 12 fitted inside the end of one section 2 and having a tenon engaged within the groove 4 of the other section 1. Four hollow sections (including sections 24, 25) may be connected together by four brackets 26 engaged in their ends to constitute a door. The door hinge comprises a plate 30, having a tenon 14, Fig. 5, on one face which engages within the groove 4 in the section 24, the enlarged base 32 of the plate 30 having a hole (not shown) which receives a hinge pin (not shown) carried by a further plate 35 similar to the plate 30, the plate 35 being attached to the section 1 by the tenon 14 which engages a groove 4 in the section 1. A screwed bore 34 in each plate receives a clamping screw which serves to bear against the bottom of the groove 4 to secure the plate. A fitting 37 carrying a packing 36 also has a tenon 14" engaged in the groove 4 in the section 1, the tenon 14" being of reduced width to allow transverse adjustment in the position of the fitting 37, thereby compensating for doors which may be made of different thickness. Panelling members 20 or glass sheets 29 may be retained by resilient elements 17 each having a tenon engaging the grooves 4.

Abstract: 1,227,886. Mandrels for making pipes RECHERCHES ET APPLICATIONS DES PLASTIQUES DANS L'INDUSTRIE ET LE BATIMENT. 19 Aug., 1968 [17 Aug., 1967], No. 39563/68. Heading F2P. A radially expandible, and contractible, mandrel, which is adapted to be erected vertically for the manufacture of tubes, or tanks, of reinforced plastics by winding around the mandrel bands of fibre impregnated with polymerizable plastics material, is formed of a number of individual sectors each of which comprises a rectangular metal frame 1 with sides 2-5, cross-bar 6, and bracing bars 9, 10 and a second rectangular frame 7 perpendicular to the frame 1, and secured to the vertical centre line of a flexible metal sheet 12 which has L- section reinforced edges 17 with pairs of arcuate upper and lower stay-members 22, 23 and 35, 34 having series of holes 24 and 35 which are individually co-operable with holes respectively in corresponding brackets 21, 20 or 33, 32 on a side 2, or 3, of the frame 1 so that the curvature of the sheet can be adjusted. To erect a mandrel, the stay-members 22, 23, 34, 35 are adjusted so that each sheet 12 corresponds to the desired overall circumference, the sectors then being arranged side-by-side in circular formation and connected together by turnbuckle connections 50 which threadedly engage between adjacent pairs 28, 30 and 29, 31 of oppositely threaded pivotal brackets to leave gaps between the neighbouring sheets 13. Adjustable rods 40 are connected between pins 27 on brackets 26 on the sides 2 of the frame 1 and a base 44 placed on the ground on the axis of the completed mandrel. After bands, e.g. of fabric impreg-' nated with polymerizable resin, or glass fibre, have been wound tightly upon the mandrel and polymerized the connections 50 are shortened to reduce the circumference of the mandrel so that wound bands can be slid axially to allow the winding on of more bands. When the pipe, or tank, is completed the mandrel can be dismantled for withdrawal.
