Title: Photographic photosensitive materials and processing
Inventor: YUDELSON JOSEPH SAMUEL
IPC: C08F8/14
Filed: 1968-07-12
Abstract: 1,240,707. Photographic light-sensitive materials. EASTMAN KODAK CO. July 12, 1968 [April 22, 1968], No.7222/71. Heading G2C. A photographic light-sensitive material comprises a support bearing a layer of a polymer having free hydroxy groups and vinyl anthranilate units in which a radiation-sensitive palladium compound has been imbibed or incorporated. The polymer may be copoly (vinyl alcohol-vinyl anthranilate-vinyl succinate). Palladium compounds include palladium oxalate, co-ordination compounds of palladium, e.g. K 2  PdCl 4 , K 2 Pd (oxalate) 2  and Pd(NH 3 ) 4  Cl 2  and complexes of PdCl 2  with organic compounds. After exposure to light the material is physically developed to give a visible image. Physical developers for the material contain a heavy metal salt, e.g. of Ni, Co, Fe, Cu, Cr, Pd, Pt, Ag or Au; a reducing agent for the heavy metal ion, e. g. formaldehyde, water-soluble hypophosphites, hydrosulphites and borohydrides, borane amines and hydrazine; and a complexing agent for the heavy metal ion, e.g. NH 4  Cl, aspartic, malic, citric or glycolic acids, sodium or potassium citrate, glycolate or succinate or potassium sodium tartrate. The developer may also contain a complexing agent for palladium ions such as gluconic acid, saccharic acid and quinic acid and water-soluble salts thereof, and a minor amount of stannous ions may also be present. After exposure, the lightsensitive palladium material may in certain cases be washed to remove unexposed palladium compound and then immersed in the physical developer bath to obtain a visible image. Alternatively the exposed material may be brought into contact with a receiving sheet containing physical developer solution and heated to promote migration of unexposed palladium compound to the receiving sheet where it is developed. The light-sensitive palladium material may be used to prepare lithographic printing plates by developing heavily using an ink-reception heavy metal or to make printed circuits using a non-conductive support and a heavy metal such as Cu, Fe or Ni.

Abstract: 987,633. Making cartons. LIQUID PACKAGING Ltd., and T. N. GAUNT. May 16, 1963 [Feb. 27, 1962], No. 7611/62. Heading B5D. [Also in Division B8] A paper board blank coated on one side with thermoplastic resin is formed into a tube with rectangular cross-section, placed on a former (Fig. 2) and its base folded as in Fig. 4; the flange 46 is then gripped first by heated jaws 42, 44 and then by cold jaws for heat-sealing; this flange is then folded on to the base with the coated side of the extension 40 towards the base and is secured thereto by pressure of a heated platen 48 (Fig. 5) and then a cold platen. The platens 48 preferably extend across the entire base to consolidate the whole base.

Title: Improvements in and relating to weighing scales
IPC: G01G3/08
Filed: 1946-03-22
Abstract: 604,201. Spring balances. WRIGHT, G. E. March 22, 1946, No. 7622/45. [Class 143] In a weighing scale, particularly for domestic and cookery use, having at least two flat springs each anchored at one end and rigidly interconnected at their opposite ends by a member carrying the load, a further flat spring is combined with said member, the other end of which spring engages an abutment after a predetermined flexing of the other springs whereby a greater movement is obtained for light loads than for heavier ones. A back plate 1 carries blocks 2, 3 to which are anchored the parallel springs 4, 5. Their free ends carry blocks 6, 7 connected by a rigid member 8 comprising the bent over edge of a triangular member 9 which has an upwardly turned flange 11 over which a scale pan can engage. Alternatively, the member 9 may extend above the casing. A pointer 12 and scale 13 indicate the extent of flexing of springs 4, 5. The pointer pivots on a member 14, adjustable by a screw 15 for zeroising, and has an arm 17 engaging arm 18 on the block 7. Zeroising may, alternatively, be effected by adjustment of the flexing of one of the springs. A pin and slot 25, 26 limit movement of the member 9. A third spring 30, anchored to block 6, after a predetermined flexing of springs 4, 5, engages an abutment 31. Thus, the scale may register ounces up to one pound from the zero 32 to the mid point 33, and from 1 to 4 pounds over the latter half.

Title: Improvements in or relating to the manufacture of plasters
IPC: C04B24/30
Filed: 1935-03-13
Abstract: A slurry of a calcium sulphate plaster, such as fine boiled hemihydrate, or accelerated anhydrite plaster, is mixed with such a proportion of a cold-hardening urea- or thioureaformaldehyde resin syrup, that the set mass contains 5--25 per cent of resin, and the mass is cast, moulded, sprayed, &c., and sets to a hard, glossy mass which can be worked.  The syrup may be stabilized, but preferably is not, and may be mixed with acids or salts to accelerate its setting. The elasticity of the mass may be varied by the addition of glycerol, sugars, alginates and the like. Fillers such as paper, wool, cotton, ground glass, silver sand, marble or alabaster chippings, or set plaster as described in Specification 451,113, [Group V], may be added to reduce the tendency of the surface to crack.  Specification 381,155, [Group V], is referred to as describing a plaster block suitable for veneering with the composition.

The thrust of the rod 2 causes the leg. 3b to be inclined to its former position and also the leg is bent with 'the bend of the U as fulcrum with the result that the bend of the leg 3b is compensated and the leg 3a moves parallel to itself without variation of the angle between it and the rod 2. The free end of the leg 3a is slotted to engage a ballpin 10 on a transmission lever pivoted at 9.

In vertical section each furnace is arranged as in Fig. 3 which shows the evaporating furnace. The outer walls of this furnace are lined with steam generating tubes 8 . . . . 10, and it contains in its upper portion radiantly-heated platens 17 of generating tubes. The furnace has a top outlet into a lateral pass leading into a downpass, the passes locating secondary and primary superheaters 18, 19 and an economizer 20. The reheating furnace 4 has outer walls 11, 12 lined in part with reheater tubes R and in part with evaporating tubes E and contains platens of reheater tubes arranged and disposed as for the platens 17. The outlet passes from this furnace contain secondary and primary reheaters and an economizer. The super-heating furnace 5 has outer walls 13 . . . . 15 lined in part with superheater tubes 5 and in part with evaporating tubes E and contains platens of superheater tubes arranged and disposed as for the platens 17.
