Title: Roller leveller straightening machines for metal plates, sheet or strip
Inventor: LAWSON KENNETH THOMAS
IPC: B21D1/02
Filed: 1960-10-18
Abstract: 914,020. Straightening. HEAD WRIGHTSON & CO. Ltd. Oct. 12, 1961 [Oct. 18, 1960], No. 35747/60. Class 83 (4). A roller leveller straightening machine has means for longitudinally and/or laterally tilting the work rolls which comprises two co-operating wedge members rotatable relative to one another. An upper roll assembly 12 includes work rolls 13, mounted on a framework 14, backed by rolls 15 in brackets 16. The distance between the upper roll assembly 12 and a lower roll assembly 17, having work rolls 18 backed by rolls 21, is adjusted by a hand wheel 29 which operates, through connecting rods 30 and gearboxes 31, screw jacks to raise or lower a crosshead 22 carrying the upper roll assembly 12. The assembly 12 is supported on the crosshead 22 by spring assemblies 23 pivoted at 24 to a plate 25 in turn hinged through brackets 26 on an axle 27 in bearings 28 on the crosshead 22. The roll assembly 12 is tilted longitudinally, that is in the direction of travel of sheet through the machine, by turning the axle 27 by a lever arm 32 and, through arms 34 bearing on the plate 25, rocking the plate 25 and thus the roll assembly 12. The rolls 13 are flexed by adjusting the backing rolls 15 by turning a hand wheel 35 which, through rods 36 and gear-boxes 37, actuates cams bearing on the brackets 16. The lower roll assembly 17 is tilted laterally by a rotary wedge device 38 comprising two wedge-shaped plates 39, 40, the upper plate 39 fixed to the frame 19 of the roll assembly 17 and the lower plate 40, turnably mounted on a pin 41 on the floor 42 of the machine. The plates 39, 40 are connected by a common pivot pin 43 and the plate 40 is turned by a hand wheel 45 screwing on a spindle 50 connected by a rod 51 to a bracket e2 on the plate 40, so that the roll assembly 17 tilts laterally, guides 44 preventing its rotation. The wedge plates 39, 40 could be arranged to tilt the assembly 17 longitudinally, lateral tilting adjustment could then be effected by lever means. Alternatively, one wedge device could be provided for each roll assembly 12, 17, or the upper roll assembly only could be tilted by wedge means. Both wedges 39, 40 of a wedge means could be rotated in opposite directions, by means Figs. 8, 9 (not shown).

Filed: 1960-08-11
Abstract: 956, 463. Photo-electric control of photographic colour printing. KODAK Ltd. Aug. 11, 1960 [Aug.14, 1959],No. 36074/63. Divided out of 956, 462. Heading G1A. [Also in Division G2] In a photographic colour printing apparatus of the type in which subtractive filters are inserted into the printing beam to terminate individual exposures, the intensities of the primary colours are measured before the light reaches the point of insertion of the filters. Light from source S passing through negatives N to printing paper 12 is sampled by a partial reflector 17 which directs light on to photo-cells Cr, Cg, Cb sensitive to the primary colours. The cells control a timer 20 of the condenser and thyratron type which operates the filters Fc, Fm, Fy. The filters have a controlled amount of absorption in colours they do not primarily absorb. This reduces the colour correction to 40%-80% whilst maintaining full exposure correction. The degree of colour correction may be different for each primary colour, 72% for the red, 58% for green and 75% for blue being preferred. Specification 660,099 also is referred to.

The intermediate condensation product itself is prepared by mixing from 3 to 1 mols. of an R1-substituted caffeic acid chloride or anhydride with from 1 to 3 mols. of quinide (or its derivative of formula I in which Y represents hydrogen) and heating to between 110 DEG  and 180 DEG  C. for 15-90 minutes.  In examples: (1) carbonylcaffeyl chloride and quinide are heated slowly to 180 DEG  C., yielding 1,4,5-tri-carbonylcaffeylquinide; (2) as in (1), heating to 150 DEG  C. and treating residue in dioxane with NNH4OH under nitrogen overnight, when acidification yields the amide of 1,4,5-tri-caffeylquinic acid; (3) the quinide from (1) is saponified with ammonia as in (2); (4) hydrolysis of 1,4,5-tricarbonylcaffeylquinide with aqueous acetic acid gives 1,4,5-tricaffeylquinic acid, which (5), with 3 per cent barium hydroxide yields 1,4-dicaffeylquinic acid; (6) the amide from (2) is hydrolysed with barium hydroxide to the amide of 1,4-dicaffeylquinic acid.

The pin 6 may have two keys 7, as shown, which are spaced so as to engage the apertures 8a, Sa, in the opposite sides of the socket portion 4. Otherwise there may be a single key 7 adapted to engage the single aperture 8 in the portion 3.

The chain links have to be inclined to each other at an angle of 96 degrees in order to bring the apertures 8 and 8a into alignment. In its passage over the return sprockets at each end of the conveyer in normal operation the maximum angle of inclination between the links is 60 degrees.
