Title: Conveyed article controlling devices
IPC: B65H31/30
Filed: 1963-10-15
Abstract: 1,003,360. Endless conveyers. BROOKHIRST IGRANIC Ltd. Oct. 15, 1963 [Oct. 29, 1962], No. 40607/63. Heading B8A. A conveying system for stacks of newspapers comprises a supply conveyer 2, a receiving conveyer having portions 4, 6, 8 adjacent the end of the supply conveyer and extending transversely thereof, and control devices 12, 14 which engage each stack of newspapers as it passes from the supply to the receiving conveyer so as to oppose the initial movement of the stack in the direction of the receiving conveyer and cause it to turn through 90 degrees. The supply conveyer 2, comprises a pair of endless belts 2a driven and supported on a plurality of rollers 2b whilst the sections 6, 8 of the receiving conveyer comprise single endless belts driven and supported on rollers 8b. The centre portion 4 of the receiving conveyer comprises a plurality of rollers 4a driven in either direction by an endless belt thereunder, depending on whether the stack is to be conveyed to the receiving portion 6 or 8. Each controlling device 12, 14 is pivotally mounted on a vertical shaft 12a adjustably secured to the conveyer framework and comprises a lobe-shaped engaging surface 12d the near parallel ends of which are secured to bearing blocks 12e, 12f at top and bottom. These blocks are freely mounted on the shaft 12a, the top one 12e being supported on a shoulder thereon. Midway between the two blocks 12e and 12f, a stop block 12m is secured to the shaft 12a by a pin 12n. A projecting portion 12o of the stop block 12m is used to anchor in vertically spaced relationship, two tension springs 12s, 12t, which resiliently bias the rotatable control device 12 or 14, to its normal angular mid-position relative to the stationary shaft 12a. The other ends of the springs are coupled to hooks 12w mounted on a bracket 12u which is bolted to the inside surfaces of the engaging surface 12d. A stop bracket 12x having a pair of wings 12z is adjustably mounted between the parallel ends of the engaging surface 12d and wings 12z engage the projecting portion 12o and act as stops to limit the rotation of the device 12, 14. Each stack of newspapers comprises a lower batch LB folded one way and an upper batch UB folded the other way. The heights of the control devices 12, 14 are such that if the stack turns in the direction (left, Fig. 5) where the folds of the papers in the lower batch are adjacent the control device, the latter is restricted to the height of the lower batch. If however the same stack is to turn to the right (Fig. 5), the folds are in the upper batch and so the control device must extend up to the top of the stack. This arrangement is to prevent displacement of one batch relative to the other.

Title: Process for accelerating the transesterification process for the production of high molecular weight thermoplastic polycarbonates
IPC: C08G64/30
Filed: 1963-10-17
Abstract: In the manufacture of polycarbonates by effecting a transesterification between (a) an ester of carbonic acid and (b) a dihydric phenol or a mixture thereof with a dihydric alcohol, the transesterification is carried out in the presence of an unstable monomeric and/or polymeric ester which evolves carbon dioxide.  The latter acts as an entraining agent for the removal of monohydroxy compounds from the reaction melt.  A mixture of unstable esters may be used which decompose at different temperatures. The unstable esters may be added at the beginning or during the transesterification and may be certain dialkyl, dicycloalkyl or diaryl carbonates or similar mixed dicarbonates, or may be certain biscarbonates of dihydric phenols and monohydric alcohols. Alternatively, there may be added to the reaction mixture substances capable of forming by transesterification unstable carbonates or polycarbonates, suitable substances being certain aliphatic or cycloaliphatic mono- or dihydric alcohols. The diaryl carbonates used for the transesterification may be diaryl carbonates or bis-phenyl carbonates of dihydric phenols. Examples describe the manufacture of polycarbonates by reacting (1)-(4) and (6) bisphenol A with diphenyl carbonate in the presence of hexylene-1:6-bis-phenyl carbonate, hexane - 1:6 - diol, n - dodecyl alcohol, n-stearyl alcohol, 2:2-bis-(4 - (beta - hydroxyethoxyphenyl) - phenyl) - propane, 1:4 - dimethyl - butylene - 1:4 - bis - (phenyl carbonate) or 3 - methyl - propylene - 1:3 - bis-(phenyl carbonate); (5) bisphenol A and hydroquinone with diphenyl carbonate in the presence of 1:6-hexylene-bis-(phenyl carbonate).

Abstract: 1,235,505. Feeding articles. W. GASSERT. 30 Aug., 1968 [27 Dec., 1967], No. 41613/68. Heading B8S. Articles are introduced into container 2 to be fed out one by one down vertical channel 40 of magazine 3, the container 2 having been filled with oil through openings 5 and closed by lid 6. The oil is given two movements, a rotational movement by oil fed into the container through jets 49 via pipe 32 and jet 50 via pipe 36 from respective piston-and-cylinders 16 and 17; and a reciprocal up-and-down movement by oil introduced into magazine 3 via pipe 30 and pipe 7 from respective cylinders 14 and 15, the oil reciprocating between the cylinders. In this way the articles are agitated so as not to block the entrance from the container 2 into the channel 40. Air from pipe 21 is governed by valves 22 and 23 so as to flow into the tops of the cylinders to cause the movement of the oil. Feeding articles to container 2 (Fig. 9)- Batches of articles are fed into container 2 from chamber 61, the articles entering at 64 and falling at 65 in front of piston 62 which is connected by chain 74 to the piston 77 of vertical cylinder 75. When the supply of articles in magazine 3 falls below the entrance to pipe 84, the oil from container 2 passes through the pipe 84 and via pipe 81 enters the top of cylinder 75 to cause the piston 77 to descend and permit spring 70 to move the pusher 62 leftwards to push the articles from chamber 61 into the top of the container 2.
