Title: A method of manufacturing gramophone records carrying visual material
IPC: B29C43/18
Filed: 1958-10-29
Abstract: 890,417. Laminates. BARDOWICKS, L. Oct. 29, 1958 [Oct. 30, 1957], No. 34716/58. Class 140. [Also in Group XXXVIII] A gramophone picture-record of the type in which printed layers on either side of a central core are retained by transparent outer layers in which the sound grooves are impressed, has at least one additional layer, having a surface area less than that of the printed sheets, on each side between the central core and the printed layers. This serves to prevent stretching and tearing of the printed layers due to the action of the record stamping press. The core is preferably of thermoplastic material, and the outer layers may be of cellulose esters. As shown, a record may be made in a mould comprising two halves 1 and 2 hinged together. 10 and 11 are centring pins, 10 being fixed and 11 axially movable under spring action. A transparent foil 14, having a central hole, is placed over the pin 10, followed by a similarly perforated printed paper sheet 15. An insert 16 of soft polyvinyl chloride is then laid over the pin, followed by a heated lump 19 of core forming material and a further insert (not shown) similar to 16. Another transparent foil 17 and printed paper sheet 18 are placed on pin 11. The mould is then closed and inserted in a press, heated and then cooled. The foil inserts may be circular, or may be longer in the direction normal to the axis about which the halves of the mould pivot than in the direction parallel thereto, or two circular inserts may be used on each side, having their centres displaced from one another along a line normal to the pivot axis but partially overlapping. Reference is also made to the use of a green leaf of a tree as the insert.

Title: Photographic transfer process and materials therefore
IPC: C09B1/515
Filed: 1968-07-23
Abstract: 1,243,045. Photographic transfer materials and process. INTERNATIONAL POLAROID CORP. July 23, 1968 [July 24, 1967 (2)], No.35133/68. Heading G2C. Photographic transfer process comprises (1) developing an exposed silver halide emulsion in the presence of a non-diffusible compound containing a colour-providing moiety, whereby there is formed imagewise a reaction product of this compound, which product undergoes intra-molecular cyclization with elimination of the colour-providing moiety, and (2) transferring at least part of the eliminated colour-providing moiety to a superposed stratum to form a colour image therein. The non- diffusible compound is either (A) a compound which couples with oxidized colour developer to form the desired reaction product, or (B) a developing agent, the oxidation product of which is the desired reaction product; the colour-forming moiety may be the residue of a dye or dye-precursor. Normally compound (A) forms a negative transfer image; positive transfer images may be formed by the following techniques:- (a) using a photo-sensitive material containing (i) a non-diffusible coupler (which immobilizes colour developer oxidized during development) and (ii) a prefogged emulsion which oxides residual colour developer; (b) a similar process but using physical development nuclei in the material or processing liquid instead of the prefogged emulsion; (c) using a directpositive emulsion; (d) developing with a black-andwhite developer, fogging and redeveloping with colour-developer; (e) using a material containing a Schiff base of a colour developer, developing with acidic TiCl 2 , and then applying alkali; (f) using a material containing a coupler which forms a diffusible development inhibitor, and a spontaneously developable metal salt emulsion layer. Using (B), a positive transfer image is formed by developing a photo-sensitive material containing (B) and physical development nuclei with a developing agent and a silver halide solvent, so that the undeveloped silver halide is complexed and reacts with (B), redox reaction between (B) and oxidized developing agent being prevented by either using a scavenger which reacts with the oxidized developing agent or using a developing agent which forms a non-diffusible reaction product. Negative transfer images may be prepared by (a) using (B) as developing agent, or (b) developing with a developing agent so that the oxidation product thereof reacts with (B). The invention also relates to a photographic product containing a support, a silver halide emulsion layer, and a non-diffusible compound as defined above.
