Filed: 1956-10-18
Abstract: The invention comprises hydantoin compounds of the general formula <FORM:0818724/IV (b)/1> (wherein R represents hydrogen or an alkyl group of not more than 4 carbon atoms), and the preparation thereof by subjecting the corresponding hydrindone-(1) of the formula <FORM:0818724/IV (b)/2> to the Bucherer hydantoin synthesis to produce the compound in which R is hydrogen, and alkylating this if desired.  The products possess anticonvulsant properties.  In examples: (1) 4-chlorohydrindone-(1) is warmed with ammonium carbonate and potassium cyanide in aqueous methanol to produce 4-chlorospirohydrindenyl - [1 : 51] - hydantoin: (2) the product of (1) is converted to its 31-methyl derivative by reaction with dimethyl sulphate in aqueous caustic soda.  The Provisional Specification comprises compounds (analogously prepared) of the general formula <FORM:0818724/IV (b)/3> wherein R represents hydrogen or a lower alkyl radical and ring A bears at least one substituent, e.g. an alkyl (e.g. methyl or ethyl) or alkoxy (e.g. methoxy or ethoxy) radical or a halogen atom.

Title: Improvements in or relating to rotary printing machines
IPC: B41L35/26
Filed: 1958-10-06
Abstract: 845,829. Rotary printing machines; sheet delivery apparatus. DAVIDSON CORPORATION Oct. 6, 1958 [Oct. 29, 1957], No. 31776/58. Classes 100(1) and 100(2) A rotary printing press having a cylinder 10 on which a printing plate is mounted and a pressure roller 27 to assist in delivering a printed sheet from the cylinder to an ejection mechanism and sheet receiving tray 58, includes means for moving the roller into and out of sheet engaging position during normal operation of the printing press so that the roller engages the sheet only after the leading edge thereof has passed under the roller, and manually actuated means for moving the roller away from the cylinder a distance sufficient to give access to the roller for cleaning purposes. The cylinder 10 which carries a printing plate and platen surface is rotatably journalled in machine side frames 11 and has a 180 degrees arcuate cam 12 mounted thereon. The cam 12 cooperates with roller 14 on a lever 15 fixed to a rod 18. The rod 18 has a lever 19, mounted outwardly of the frame 11, and a roller 20 is mounted on the lever 19. The roller 20 is spaced from lever 19 by a pin 21 which passes through a hole 23 in the frame 11. A tension spring 24 biases the lever 19 anticlockwise thus biasing the roller 14 towards the cam 12. Rollers 27 are mounted on a rod 28 fastened between horizontal bars 29. Bar 29 rests on stud 30 and is pivoted at 31 to a bar 32. The bar 32 is pivoted at 34 and is connected to a toggle device 36. The bar 29 is held in position by tension spring 41 and compression spring 39 of toggle device 36. A delivery roller 42 is secured on shaft 43 and is driven by gearing from the drive for the cylinder 10. The shaft. 43 is provided with a pulley 53 and a belt 55 which runs over a pulley 54 on shaft 50. Shaft 50 also carries a delivery roller 49 which delivers sheets into the receiver 58. Delivery guides 56, 59 are also provided. Co-operating with the roller 42 are rollers 46 each mounted between pairs of plates 48 pivoted on rod 28. In operation when roller 14 runs off cam 12 the action of spring 24 causes roller 20 to engage bar 29 and lift the rollers 27 out of contact with the cylinder 10, whereas when the cam 12 acts on the roller 14 the rollers 27 are moved into contact with the cylinder 10. The cam 12 extends over slightly less than 180 degrees and ensures that the rollers 27 contact the cylinder after the leading edge of the sheet to be delivered has passed the rollers and are lifted from the cylinder before the plate portion of the cylinder passes beneath the rollers. In order to clean the rollers 27 the bar 29 is pulled to the left as viewed in Fig. 1 so as to pivot the bar 32 anticlockwise about the pivot 34 to a position where it abuts a stop 60. The bars are maintained in this position by the toggle device 36. The rollers 27 and delivery rollers 46 are thus also moved to the left thus allowing access for cleaning.

[Also in Group XL (a)] In a mechanism for adjusting the spacing between two relatively displaceable elements, e.g. the grids 11, 12 of a klystron, and indicating the adjustment, two adjustment members 23, 33 having co-operating screw threads and carrying co-operating marks such as 46 to give an indication of the relative spacing are coupled one to each element so as to alter said spacing by a screwing action. The zero may be set by adjusting one member relative to its element and the other member without altering said spacing. Flanges 17, 18 which are connected to the grids 12, 11 of a reflex klystron, both accommodate an adjusting rod 23. Said rod carries threads 31, 29 of different pitch; the latter being screwed into flange 18. A second adjustment member 33 comprises a sleeve over rod 23 and carries like internal and external threads, the former engaging threads 31, and is locked within this section of its length to flange 17, by nuts 38, 39. Because of the threading on sleeve 33 it can be rotated with nut 38 loose and both locking nuts and rod 23 prevented from rotating to bring its top opposite a zero marking 46 on the rod 23 without moving the flange 17. The nuts 38, 39 are then tightened and the klystron is tuned by rotating rod 23. Rod 23 carries annular markings 46 at its upper end symmetrically disposed with respect to the zero 46 and the sleeve 33 carries at its upper end a contiguous member 42 the upper face of which carries radial calibrations (Fig. 5, not shown) to indicate the relative angular position of rod 23. Specification 606,794 is referred to.
