Patent GB-486107-A (GB)
Title: Improvements relating to colour-photography
IPC: G03C7/30
Filed: 1936-09-28
Abstract: 486,107. Colour photography; stripping films. WEBB, K. W. C., and GALL, R. L. B. Sept. 28, 1936, Nos. 26199/36 and 16607/37. [Class 98 (ii)] Superimposed silver images in multi-layer photographic material are isolated by transfer from the material to a metal plate in the form of a metallic image and thence to a transparent support. In one example, a multi-layer film comprises three layers sensitive to blue, green, and red respectively, separated by inactive layers and mounted upon a celluloid support. After exposure, developing and fixing, the whole film may be hardened bv immersion for 15-20 minutes in a 5 per cent solution of alum. The first layer is then bleached as with ferric chloride, the bleaching being arrested by a weak solution of sodium carbonate. After rinsing the film is immersed in a deposition agent, e.g. 20 per cent solution of sodium chloride, potassium chloride or sodium sulphite. The first layer is then pressed into contact with a clean copper plate for 7-10 minutes. The silver chloride is converted to silver which adheres to the copper plate as a deposit. The copper plate is then made the anode of an electrolytic cell containing, for example, copper sulphate or sulphuric acid or both. Upon the passage of a small current, the silver deposit is loosened, and it is then transferred to a film of dry hardened gelatine mounted on a sheet of celluloid. The plate which has had weak hydrochloric acid poured over it, is lightly pressed onto the gelatine and the silver deposit adheres to the gelatine. The gelatine remaining in the first yellow printing layer is removed by gentle .friction and stripping, the intermediate film accompanying it. The procedure is then repeated for the second and third separation negatives. The multilayer film may comprise two outside support lavers of celluloid, and in this case, one sensitive layer and the support are stripped off before the other layers are developed and fixed and the middle layer image isolated by the transfer method described. In another modification, a layer of waterproof varnish is mounted between the blue sensitive and green sensitive layers. Upon developing and fixing, a negative image is formed in the first layer only. This image is transferred to a transparent carrier as described above, the gelatine removed by scrubbing, and the varnish layer dissolved off. After redeveloping and fixing, the remaining negative images are transferred. A varnish layer may be substituted for the inactive layer between the greensensitive and red-sensitive layers. The inactive layers may be of gelatin which melt or dissolve in water at different temperatures, e.g. at 80-90 F. and 115 F. Upon immersion at these temperatures the layers can be separately stripped. Specification 440,736 is referred to.

Title: Chromium electro-plating of titanium
IPC: C25D5/14
Filed: 1971-04-19
Abstract: 1338515 Chromium electro-plating of titanium; cleaning Ti alloys SUPERIOR PLATING CO 19 April 1971 [20 April 1970 5 March 1971] 26234/71 Headings C7B and C7E A method for depositing a hard chromium electro-plate on a Ti or Ti alloy substrate comprises (a) electro-plating a layer of Cr on the substrate, (b) subjecting the electro-plated substrate to a heat treatment at a temperature in the range of 1600‹F. to 1900‹F. for a time sufficient to allow for diffusion bonding of the Cr to the substrate but brief enough so as not to have any significant effect on the physical properties of the substrate, (c) cooling the substrate to approximately room temperature, and (d) electro-plating on the first Cr layer a layer of hard Cr. The substrate may be of Ti alloys containing (a) 6 per cent Al and 4 per cent V or (b) 7 per cent Al and 4 per cent Mo. It can be initially honed, chemically or mechanically polished, and be activated. Activation can be either by anodic treatment in a solution of glacial CH 3  COOH and HF using a Pb or stainless steel cathode and an anode cathode distance of # inch (see Example I) or by soaking in an acidic etching solution, e.g. of H 3  PO 4 , H 2  SO 4  and HF (see Example III). The Cr may be deposited from a conventional bath e.g. of H 2  CrO 4 , H 2 SO 4  and H 2 O. The heat treatment may be in an induction furnace, e.g. in an inert atmosphere of He or Ar. The cooling may be in H 2 O, air or an inert atmosphere. The Cr plated substrate may then be subjected to shot peening to increase its fatigue strength it may be activated by anodic treatment in a Cr plating solution and the second Cr layer then be deposited by switching the leads. Where worn Ti parts are to be electro-plated, additional Cr may be electro-plated with the initial Cr which, after the heat treatment and cooling, can be machined to size thus replacing worn Ti with Cr.

Title: An improved device for lifting flat slabs such as pavement flags
IPC: B65G7/12
Filed: 1948-10-08
Abstract: 645,790. Lifting-dogs. RUTHERFORD, W. Oct. 8, 1948, No. 26259. [Class 78 (iv)] A device for lifting pavement flags or the like comprises two or more pairs of pincer-like arms, the corresponding arms of which are rigidly connected, while the arms of each pair are pivoted together and have their engaging ends shaped to engage the edges of the flag, one arm being extended beyond the pivot to form a lever, the inner end of which may be raised relatively to the other arm, so that on raising the lever the engaging members of the pincerlike arms first press against the sides of the flag, further raising serving to lift the flag. As shown in Fig. 1, arms 1 rigidly connected by a member 3 and arms 2 rigidly connected by a member 4 are connected by pivots engaging projecting pieces 5 on the arms 1 and lugs 2a on the arms 2. The arms 1, 2 are formed with projecting portions 1a, 2b respectively which have respectively welded to them angle pieces 6 and flat plates 7 for engaging the flags, the vertical flange 6a and the flat plates 7 lying in planes substantially parallel to the planes of the flag edges and such that the lower ends of the flanges 6a and of the plates 7 engage the edges of the flag first. The arms 2 form levers joined by a slidable and rotatable lifting arm 8 normally secured against sliding by pins 9 and washers 10 but adjustable. Links 11 pivoted to the levers 2 and having pin-and-slot connections 11a to the arms 1 maintain the device in a position facilitating engagement of a flag. The lugs 2a rest on the flag before it is gripped and ensure that the angles 6 engage the flag before the plates 7. The flanges 6a are shallower than the edge of the flag so that the flag may be aligned with a flag already in place before being released. The lifting-rod 8 is preferably midway between the engaging ends of the device, but may be otherwise positioned to facilitate laying the flags on an inclined surface.

Title: Improvements in or relating to cement applying apparatus
IPC: A43D25/18
Filed: 1955-09-14
Abstract: A cement applying apparatus, of the type in which a rod of thermoplastic current is progressively fed into the apparatus in which it is melted at a controlled rate and applied to the work, comprises a stationary unit and a rotary unit arranged to co-operate with the stationary unit and mounted for rotation relative thereto about an axis, the two units being shaped to provide a passage at least partially encircling the axis, part at least of which passage lies along a groove in the rotary unit and encircling the axis, there being an inlet into said passage and an outlet from said passage to which cement is urged when the rotary unit is rotated relative to the stationary unit <PICT:0849652/III/1> <PICT:0849652/III/2> in the operation of the apparatus.  In a machine similar to the second illustrative example of the parent Specification there is included a member which pushes the rod of cement into contact with the rotary unit at the beginning of work and withdraws it therefrom at the end of work.  As shown, (Fig. 1) a rod R of cement is fed into a bore 254 in block 252.  The toothed arcuate member 260 is operated by a treadle which also causes the disc 152 to start rotating.  The rod even if it is of soft or limber p  material is urged by the member 260 into contact with the rotary unit, and the continued movement of the member brings roller 282 into contact with inclined surface 294 thus disengaging the member from the rod until such time as the treadle is released, when member 260 again engages the rod of cement and partially withdraws it so that the tail portion T is allowed to cool and solidify. The pivoted work-table 44 (Fig. 2) is raised and lowered and the feed rollers 18, 28 for workpieces are started and stopped by the same treadle which operates the member 260.  The groove around the rotary unit may be of arcuate or rectangular cross-section; in one embodiment it subtends an angle at the axis of about 270 degrees while in another embodiment two such grooves connected by a passage subtend a total angle of about 540 degrees at the axis.

Inventor: WILCOCK ALBERT
IPC: H04N1/08
Filed: 1950-11-01
Abstract: 704,152. Copying-telegraph transmitters. POSTMASTER GENERAL. Nov. 16, 1951 [Nov. 1, 1950], No. 26700/51. Class 40 (3) In facsimile apparatus employing a cylindrical drum, a sheet of transparent material is wrapped around the drums to press a sheet bearing the matter to be transmitted into close contact with the outer surface of the drum, one edge of the transparent sheet being attached to the drum, whilst the opposite edge is releasably attached to means capable of adjustment in such manner that the transparent sheet when wrapped around the drum is placed under circumferential tension. The sheet 1 of transparent material, such as celluloid, has at each end a pressed metal strip 2 formed with recesses 4, 5 and intervening turned-over portions. One edge of the sheet is anchored to the drum by means of a hinge pin 11 passing through the turned-over portions and tunnel portions 6 of a plate 7 secured to ledges 9 of a thick plate 10 fixed to the inner surface of the drum. The non-recessed portions of the edge of the sheet 2 engage tongues 14 pressed up from the plate 7. A recess 19 in the plate 10 houses a floating plate 18, Figs. 4, 5 carrying pins 15 engaging inclined slots 21 in a longitudinally movable plate 20 and guided by slots in the plate 7. For the disengagement of the transparent sheet, the plate 20 is moved to the right against the action of springs 23 and is retained by the shouldered portion 29 of a spring latch 26. After the insertion of the sheet carrying the matter to be transmitted to slots 17 in the free end of the transparent sheet are engaged with the pins 15 and the release of the latch 26 allows the plate 20 to move to the left, thus displacing laterally the plate 18 and moving the pins 15 in the circumferential direction to bind the transparent sheet 1 into close contact with the drum 3.
