Title: Improvements relating to photocomposing equipment
Inventor: WHITING BARRY REX ANTHONY
IPC: B41B19/01
Filed: 1964-03-18
Abstract: 1,101,352. Local copying. CROSFIELD ELECTRONICS Ltd. 18 March, 1965 [18 March, 1964], No. 11435/64. Heading H4F. In photographic typesetting apparatus video signals derived by an image generating system comprising photo-electric means 4 responsive to light transmitted through, or reflected from a selected character on a matrix 3, when the latter is scanned by the raster on a flying-spot cathode ray tube 1, are supplied via a gate 5 to intensity modulate the beam of a further cathode-ray tube 6 scanned in single line fashion synchronously with the line scan of tube 1, the resulting line display being directed via a rotating mirror drum 8, on to a light sensitive film strip 9 on which the selected character is recorded. The required character position on film 9 is determined by the output of a position control 13 responsive to an input signal indicative of such position and to an input signal indicative of the angular position of the drum. The height and width of the characters may be varied independently by control unit 12 operating on the line and frame scan generators 10, 11 the width variation also allowing justification to be carried out without varying the gaps between characters or words. The different characters on matrix 3 are selected by varying the position of the raster on tube 1 in accordance with shift signals from generators 10, 11 under the control of a character selection circuit 14 and by superimposing a small signal at line scan frequency on the frame time base so that the raster is produced in the form of parallelogram characters having the slope characteristic of ITALICS may be produced. Underlining or tabulating graticules may be generated electronically and printed or hand drawn line drawings may be added to a text by means of a second image generator. The film 9 may be a positive or a negative. The image generator may be remote from the output system and more than one image generator may be associated with any one output system.

Title: Isomerization of xylene
IPC: C07C7/14
Filed: 1955-04-21
Abstract: <PICT:0787084/IV (b)/1> p-Xylene is produced by the isomerization of a mixture of xylene isomers consisting predominantly of o- and m-xylene and containing less than an equilibrium amount of p-xylene in which the mixture is fractionally distilled to separate an overhead fraction rich in m-xylene and a bottoms fraction rich in o-xylene, and in which the overhead fraction is contacted with a silica-alumina catalyst at 700-1000 DEG  F. and at a space velocity of 0.5-5.0 v/v/hour and the bottoms fraction is separately contacted with a silica-alumina catalyst at a temperature of 100-150 DEG  F. higher than that employed in treating the overhead fraction and at approximately the same space velocity.  The catalysts are preferably periodically regenerated by contacting with a free oxygen-containing gas and passing steam through the catalyst for a period of 2-20 minutes immediately subsequent to the regeneration step.  In an example, a feed consisting of ethylbenzene 5.8 weight per cent, para-xylene 18.6, meta-xylene 38.4, ortho-xylene 26.0, and C7 and C9 hydrocarbons and paraffins 11.2, is passed through a line 1 into a crystallization zone 2 where a part of the p-xylene is crystallized at a temperature of -75 DEG  to -120 DEG  F., the crystals being separated by a centrifugal filter 4.  The mother liquor is removed by line 6 and a fractionated in zone 7 into a fraction containing chiefly m-xylene which is removed through line 8 and is isomerized in zone 14 at a temperature of 700-1000 DEG  F. while the higher boiling fraction is removed through line 13 and isomerized at from 100-150 DEG  F. higher than the temperature used for the overhead fraction. The isomerized mixture is distilled in zone 19 from which ethylbenzene and lighter components are taken off by line 24.  A fraction consisting chiefly of m- and p-xylene is removed by line 25 and a fraction consisting predominantly of o-xylene by line 26.

Title: Improvements in or relating to turret lathes and like machine tools
IPC: B23Q16/04
Filed: 1942-08-21
Abstract: 565,021. Lathe turrets. BAIGENT, G. M. Aug. 21, 1942, No. 11830. [Class 83 (iii)] In a machine tool having an indexable tool carrier, such as a turret lathe, means are provided for preventing indexing of the turret unless the preceding cutting traverse has been fully completed. The bearing 12 for the turret spindle has slidable therein a rod 10 capable of engaging one of a series of recesses 38 in a plate 25 secured to the turret to prevent its rotation. When the operator traverses the turret on a cutting stroke, a stop 24 on a plate 23 rotatable and slidable with the turret engages the end of the rod 10 and carries it forward in its bearing 11, causing a dog 15 thereon to slide along a fixed cam 19. The dog first meets a projection 21, Fig. 2, on the cam and then slides along an inclined surface 20, the rotation thereby imparted to the rod being opposed by a spring 18. When the cutting traverse has been fully completed, the dog rides off the end of the cam and the spring causes it to return along the surface 22 of the cam to normal position so that the rod retracts fully together with the turret and does not engage the recess 38. If the cutting traverse has not been fully completed, the dog 15 does not ride over the end of the cam but returns along the surface 20 and is held by the projection 21 from complete retraction whereby, on return of the turret to the indexing position, the rod projects into a recess 38 and prevents indexing of the turret until the operator has again advanced it to complete the cutting traverse. The rod may have a semicircular end for engaging similar recesses in the plate 25 and the arrangement may be combined with that described in Specification 565,019, wherein a tube 14 through which the rod 10 slides is engaged by a stop on the plate 23 to actuate the mechanism for opening and closing the chuck. Specifications 565,018 and 565,020 are also referred to.
