Title: Forming of printing plates
IPC: G03G5/022
Filed: 1965-11-25
Abstract: 1,132,071. Printing plates. RANK XEROX Ltd. 25 Nov., 1965 [16 Dec., 1964], No. 50070/65. Heading B6C. [Also in Division G2] A relief printing plate is formed by bonding a layer of deformable plate forming material to a rigid support layer in areas where a relief image is required, directly or indirectly by means of electrostatic charges, urging the layers apart so that the plate forming layer is permanently forced away from the support in the unbonded areas. The plate forming material may be heat deformable and may be urged away from the support by heating until its elastic limit is exceeded while allowing the unbonded areas to sag under gravity away from the support. The deformation may alternatively be effected by subjecting the plate forming material to centrifugal forces (e.g. on a rotating drum) or, by including in the plate material a quantity of releasable subliming agent wherein deformation is effected by heating the subliming agent to generate fluid pressure between the plate material layer and the rigid support, or by using a porous support and applying a gas pressure through the support against the plate material or by applying suction from the reverse direction. The bonding in the image areas may be effected with an imagewise deposit of an adhesive substance; this substance may be an electrophotographically formed powder image on the plate material or on the support which is rendered adhesive by heat or solvent vapours. Alternatively a magnetic component may be present in the powder used to develop an electrophotographically formed image on the plate-forming material, the plate being held to the support by magnetic attraction. The deformable plate material may be bonded directly to a selenium surface bearing a latent, electrophotographically formed electrostatic image pattern, by electrostatic attraction between the plate material and the image bearing areas of the selenium surface. Numerous examples of suitable plate forming materials are given.

A sheave arrangement for limiting load moments of a jib crane comprises an outer ring 1 with a groove for a rope or chain 6. The outer ring 1 is rotatably mounted on an inner ring 2 pivotally mounted on a sheave pin 5 in a jib 8 through intermediate resilient members 4 and a shackle 3. The rotary axis of the outer ring 1 is offset from the pivotal axis of the inner ring 2. A cam 10 is rigidly mounted on the pin 5, Fig. 2 (not shown), and co-operates with a spring-loaded cam follower on an arm 11 pivotally mounted on the inner ring 2 and arranged to co-operate with a micro-switch 9 which, when actuated, either stops the crane machinery or sounds an alarm. At any particular luffing angle of the jib 8 the forces acting on the sheave cause the axes of the outer and inner rings 1, 2 to lie on the reaction R, this causes an appropriate part of the cam 10 to come under the cam follower so that the microswitch 9 is operated when the load detected by the deflection of the rssilient members 4 is the maximum for that particular luffing angle. Instead of being fixed to the jib 8 the cam 10 may be pendulously mounted on the pin 5 and remain upright under gravity, the cam profile being modified appropriately.

Abstract: 1537468 Thin film evaporator SOC ITALIANA RESINE SIR SpA 19 Dec 1975 [20 Dec 1974] 52225/75 Heading B1B A process for desalting saline water comprises evaporation in two evaporation stages 38, 40 in series wherein a higher pressure is maintained in the first (upper) stage 38, and the evaporation in each stage is by condensation heat of steam from the other stage (e.g. steam from lower to upper through pipe 43 and vice versa through pipe 27), and in which saline water flows downwardly as an annular thin film on the inside of vertical tubes in the upper first stage 38 into a similar lower second stage 40. Steam evolved in the second stage is compressed before delivery back to the first stage. The distillation residue from both stages is separated from the steam (e.g. with the assistance of demisters 26 and 45) and recovered. The sets of tubes 2 and 2' are each contained between pairs of respective plates 1 and 1a, 1b and 1c, and an intermediate plate 44 is fitted. Brine may be treated in compartment 42 with antioxidants and degassed, and passed to compartment 37. From compartment 37 brine is flowed down the tubes 2 by a film forming device detailed in Fig. 2 (not shown). Liquid falls on plate 44 to pass via pipe 24 to second stage and steam is separated through pipe 27. Condensed water from the first stage passes via pipe 28 to the second stage and condensate from both stages then passes via pipe 30 to collecting zone 31 for product water. Residual brine in compartment 41 may be recycled through outlet 33 and discharged from outlet 22. Degassing perforate tubes (e.g. 13) which are internally cooled and remove non condensible gases which pass to outlets 20 and 19. A main driving pump 24 is shown. Construction materials are brass (naval brass) for the header plates, copper nickel or aluminium brass for the heat exchange surfaces, stainless steel for bottom assembly and steel for the main evaporator casing.
