Class 83 (iv). [Also in Group X] A stationary framework comprising a steel chord tube 2 and steel diagonal tubes 1 and 11 is characterized in that (a) at least one of the diagonal tubes is flattened where it joins the chord tube and/or the diagonal tubes are brought together so that the point of intersection of their axes is located at a distance a from the axis of the chord tube not exceeding one quarter of the chord tube diameter; (b) one of the diagonal tubes penetrates or abuts the other, the tubes being welded along the line of penetration or abutment, and (c) the point along said line farthest from the chord tube axis is at a distance b of at least 65 per cent of the chord tube diameter. If both diagonal tubes are flattened the line of abutment may be perpendicular as in Fig. 2, or one of the tubes may penetrate the other as in Fig. 3. Preferably, the tube of smaller diameter is the penetrating tube. The distance x, Fig. 6, of the flattened part of the tube 1 is one quarter to one fifth of the diameter of the chord tube 2. The welded seams connecting the chord tube and the diagonal tubes are fluted seams. The Specification as open to inspection under Sect. 91 comprises also a method of forming diagonal tubes of equal diameter with both ends flattened simultaneously by flattening the middle portion of a length of tube at least equal to two diagonal tubes and then cutting the flattened portion with a saw, grinding machine or cutting torch at an angle according to the disposition of the diagonal and chord tubes. Diagonal tubes having unflattened ends are cut from tubular stock by means of a cutting torch directed radially to the tube surface and guided around the tube along the line of penetration with the chord tube, the inclination of the flame to the axis of the tube being varied to correspond to the angular setting of the diagonal tubes. This subjectmatter does not appear in the Specification as accepted.

Title: Novel polyol and polyurethane compositions and process
IPC: C08G18/32
Filed: 1966-02-17
Abstract: Phosphorous-containing polyol compounds of formula <FORM:1062869/C2/1> wherein R1 and R2 are C1-C8 alkyl radicals, A is an alkylene radical having two carbon atoms separating the valencies and a total content of 2 to 8 carbon atoms; n is 0 or an integer from 1 to 8, m is 0 or 1, and x is an integer from 1 to 3, are prepared by reacting the corresponding amine of the formula <FORM:1062869/C2/2> with the appropriate alkylene oxide or mixture of alkylene oxides in the presence of an acid or base.  In an example diethyl p-aminobenzyl-phosphonate (1 mole) is reacted with propylene oxide (8.4 mole) at 0 DEG  to 4 DEG  C. in presence of glacial acetic acid to form diethyl p[N,N-bis-(2 - hydroxypropyl)amino]benzylphosphonate. By substituting the appropriate alkylene oxide, diethyl p[N,N - bis(2 - hydroxybutyl)amino]-benzylphosphonate, diethyl p[N,N - bis(3-hydroxy - 2 - pentyl)amine]benzylphosphonate and diethyl p[N,N - bis(2 - hydroxyoctyl)-amino] benzylphosphonate may be prepared. By reacting, in the presence of caustic soda, diethyl p-aminobenzylphosphonate with propylene oxide diethyl p-[N,N-bis(5-hydroxy-2-methyl -3-oxahexy)amino]benzylphosphonate is prepared.  By increasing the proportion of propylene oxide diethyl p-[N,N-bis(8-hydroxy-2,5 - dimethyl - 3,6 - dioxanonyl)amino]benzyl-phosphonate may be obtained.  The amines of the above formula wherein m is 0 can be prepared by reacting the appropriate phenylalkyl bromide with the appropriate trialkyl phosphite followed by nitration and reduction.  The amines wherein m is 1 can be prepared by reacting the appropriate cyanophenyl alkylbromide and trialkylphosphite and reducing the resulting dialkyl cyanophenyl alkane phosphonate.ALSO:Fire-retardant polyurethanes are prepared by reacting a polyisocyanate with a polyol which contains 5 to 90%, based on the OH equivalent, of a compound <FORM:1062869/C3/1> in which R1 and R2 each represent C1-C8 alkyl groups, A is an alkylene group having two carbon atoms separating the valencies and having a total of 2 to 8 carbon atoms, n is 0 or an integer from 1 to 8, m is 0 or 1 and x is an integer from 1 to 3.  The mixture may consist of (a) a polyol having an OH number from 180 to 800 and sufficient of the above phosphorus containing polyol to give a content of 0.5 to 3% by weight of phosphorus in the final polymer. The polyol mixture may be used to prepare a rigid polymethane foam in which case a blowing agent may be used.  Specific phosphorus compounds exemplified include diethyl p-[N.N-bis (2 - hydroxyethyl)amino] benzylphosphonate and diethyl p - [N,N - bis(2 - hydroxypropyl) amino] benzylphosphonate.

Filed: 1944-04-17
Abstract: 575,911. Stereoscopic kinematograph cameras. WRIGHT, E. B. April 17, 1944, No. 7109. [Class 97 (i)] In a stereoscopic kinematograph camera, one eye-view image, reflected transversely to the axis of the lens, is reflected into the lens by means synchronized with the picture shift to move in and out of the reflecting position and allow the other eye-view image to pass directly into the lens when out of the reflecting position. In the camera shown, a semicircular mirror, mounted in a circular frame 21, is rotated about the centre of its base, in synchronism with the picture shift, by gears connecting the mirror shaft 16 to the camera shaft 32. A mirror 35 is mounted on a frame 36, which may be given angular and transverse adjustments by means of screws operable by knurled heads 43 and 51. The left eye-view image (looking from the camera 10) is formed by light passing into the lens 52 directly through the open half of the frame carrying the semicircular mirror. When the mirror comes into the reflecting position, the right eye-view image is formed by light which it receives from the mirror 35 and which it reflects into the lens. The mirror and camera shafts may alternatively be driven by separate synchronous motors. The rotary mirror may be replaced by a reciprocating mirror or totally reflecting prism.
