Abstract: 629,780. Windows. BECK, R. H. Nov. 25, 1947, No. 31241. Convention date, Dec. 13, 1948. [Class 20(iii)]  In a combined storm and window frame having vertically sliding window sashes 5, 6, Fig. 3, and storm sashes 26, 27, Fig. 5, (the latter, when both are in position, being vertically slidable to a limited extent in the same plane) the stationary frame is rabbetted at 21 along the inner faces of the side jambs 1, top bar 2 and sill 3. Storm sash guides 24 are provided in the jamb rabbets and serve as the outer guide strips for the outer window sash 5, and a channel bar 23 is provided in the rabbet in the top bar to serve as the top retaining. strip for the outer window and as a channel to receive the top sash bar of the upper storm sash 26. An auxiliary sill 25 to which the lower storm sash 27 may be latched is secured in the sill rabbet. A portion of the left hand jamb is made removable but is normally closed by a plug 15 which carries a rib 16 in alignment with the strip 4 separating the window sashes. The hole 13 which forms a pocket in the left hand jamb is somewhat higher than the height of a window sash and approximately the same width as the two window sashes together. On removing the plug 15, the lower window sash 6 can be slid to the left into the pocket 13 so as to ride clear of the guides on the right-hand jamb. On releasing the sash lines 8, Fig. 6, which connect the window sashes to spring drums 7 and hooking them temporarily to the jambs at 19, the lower window sash can be swung inwardly and removed from the frame entirely as shown in Fig. 3. The upper window sash can now be lowered and removed in the same way. The lower storm sash 27; Fig. 5, can be unlocked from the auxiliary sill 25, both storm sashes raised somewhat so that the upper sash completely enters the channel bar 23 and the lower storm sash can then be removed from the frame by a downward and inwardly-swinging movement, the lower portions of the side flanges 29 of the storm sash guides 24 being omitted to allow this. The upper storm sash can then be pulled down and removed similarly. The window sashes need not be removed to permit removal of the storm sashes. The storm sashes may be replaced by summer screens.

Title: Process for the production of high molecular weight thermoplastic polycarbonates
Filed: 1964-08-04
Abstract: In the manufacture of polycarbonates by heating (a) a dihydric phenol with a dialkyl, dicycloalkyl or diaryl carbonate or (b) a bisalkyl, biscycloalkyl or bisaryl carbonate of a dihydric phenol either alone or with a dihydric phenol, the reaction is effected in the presence of a diaryl ester of phosphoric acid or a salt thereof, e.g. of Li, K, Na, Mg, Ca, Zn, Mn or Sn. If a salt is used, this may be present ab initio and acts as a transesterification catalyst.  However, if a free diaryl phosphate is used, reaction may be effected in the presence of a basic transesterification catalyst (e.g. the sodium salt of bisphenol A) and the diaryl phosphate added only when 80 to 98% of the monohydric compound or the dihydrocarbyl carbonate has distilled off.  The diaryl phosphate, if present at the beginning of the reaction, may be used together with known transesterification catalysts, e.g. cadmium acetate.  Examples describe (a) the reaction of diphenyl carbonate with bisphenol A or a mixture thereof with 1,1-(4,41-dihydroxy - diphenyl) - cyclohexane or (b) the heating of the bis-phenyl carbonic ester of bisphenol A alone or with bisphenol A.

In winter, when cooling of the compressed air from blower 9 is unnecessary, valve 17 is closed to disconnect the pump 15 from cooler 10, pipe 16b is opened to connect header 14 to the headers 6, and valve 18 is opened to connect the engine cooling system to the pipe 12a leading to the radiators 13<SP>1</SP>, 13<SP>11</SP>, 13<SP>111</SP>, so that the latter radiators are arranged in parallel with radiators 4 in the engine cooling circuit whereby they are prevented from freezing. Partial closing of a cock 19 ensures flow through the branch 16a and a by-pass 20 permits pump 15 to continue running without building up back pressure. As an alternative the radiators 13' . . . 13<SP>11</SP> may be connected in series with radiators 4 in winter conditions. The radiator 13<SP>1</SP> is arranged close to the air intake filter 7 so that in winter the air entering the filter is heated, and the radiators 13<SP>11</SP>, 13<SP>111</SP>, may be built directly into the side of the vehicle.

Title: Improvements relating to the polymerisation of olefines
IPC: C07C2/16
Filed: 1936-11-17
Abstract: Polymers of iso and normal butenes, obtained by treating butene-containing hydrocarbon mixtures with sulphuric acid, are used, generally after hydrogenation, as motor fuels or blending-agents therefor.ALSO:Polymers of gasoline boiling range are produced by treating a hydrocarbon mixture containing iso and normal butenes in liquid or gaseous phase with 60-65 per cent sulphuric acid first at about room temperature to absorb isobutene, then at elevated temperature to absorb n-butenes, mixing the separate batches, and heating to 150-300 DEG  F. at a pressure above the vapour pressure of the olefines.  Alternatively, sulphuric acid of at least 87 per cent and at room temperature may be used in the second absorption stage. In this case dilution with water may be necessary to bring the concentration of acid in the final heating stage within the necessary range of 60-78,5 per cent.  A C4 cut may be finely dispersed in the acid by passage through a porous thimble or by using packed towers. It is preferably first washed with alkali and dried, and introduced into the bottom of the first tower down which acid flows. Unconverted C4 cut leaves at the top and passes to a second acid tower.  Acid containing olefines is drawn off from the base of each tower, the two batches are mixed, passed to a heating coil and thence to a separator for the polymer.  This is fractionated to recover dimers, mainly interpolymers of iso and n-butenes, and trimers.  The former when used as fuels or as blending agents therefor are generally hydrogenated.  The unreacted hydrocarbons may be dehydrogenated and recycled, or thermally polymerized at about 1000 DEG  F. and 1000 lb./in.2 to yield more gasoline.  In examples, a liquid C4 cut is treated first with 65 per cent, then with 87 per cent acid at 80 DEG  F., or with 65 per cent acid first at 80 DEG then at 150 DEG  F.  The combined extract is heated at 200-250 DEG F. Specification 479,940 is referred to.  The Specification as open to inspection under Sect. 91 comprises several other modifications. The liquid C4 cut may be contacted with 60-75 per cent sulphuric acid at 150-300 DEG  F. in a single stage, or with 65-87 per cent acid to absorb all the butenes, the solution then being heated to effect the polymerization.  Examples of the former modification are given, and one in which 78,5 per cent acid at 240 DEG  F. is employed. This subject-matter does not appear in the Specification as accepted.
