Patent GB-826775-A (GB)
Title: Improvements in or relating to the production of multilayer compacted granular products
Inventor: CHERRY GEORGE JOSEPH NALL
IPC: B22D7/10
Filed: 1957-01-28
Abstract: 826,775. Moulding granular material. FOUNDRY SERVICES Ltd. Jan. 24, 1958 [Jan. 28, 1957], No. 2965/57. Class 87(2). [Also in Group XXII] An article comprising at least two layers of compacted granular material is made by feeding the materials which are to form the layers separately into adjacent compartments separated by a removable partition, compacting each in its own compartment by a jolting action, removing the partition and continuing the jolting action until the materials become united at their interfaces. For example, a sleeve consisting of two contacting concentric cylinders, e.g., of sand and exothermic material respectively, is made with the illustrated apparatus in which a cylindrical partition 5 divides the space between a core former 3 and a core box 4 and is removable by means of the plunger 8 of a fluid-operated cylinder 9. The base plate 2 rests upon a vibratory platform 1 which provides the jolting action which is maintained while the granular materials are fed into the mould and compacted and also while the cylinder 5 is slowly removed. Additional material may be added to make up for the loss of volume due to the compacting of the materials and removal of the partition. The sleeve is subsequently stoved to impart rigidity and to improve the anchorage between the sand and the exothermic material. Specifications 627,678, 769,719 [both in Groups II and XXII], 772,273, 774,490, 774,491 and 775,380 [all in Group II], are referred to.
Patent GB-432505-A (GB)
Title: Improvements in recording sound photographically
IPC: G03C5/14
Filed: 1934-01-29
Abstract: 432,505. Photographic sound-records. I. G. FARBENINDUSTRIE AKT. - GES., Frankfort-on-Main, Germany. Jan. 29, 1934, No. 2968. Convention date, Jan. 28, 1933. Drawings to Specification. [Class 40 (ii)] A process of producing sound-records on a film adapted to be developed by the reversal method, comprises projecting on to the film an image of a source of light modulated in accordance with the sound, and arranging that the maximum exposure produces a density not exceeding about 1À8 units, means being adopted so that, after reversal, a minimum density due only to fog would be obtained with a maximum density of about 1À8 in the recording of sound. The means adopted may consist of an additional treatment of the film, such as a preliminary exposure, the extent of which is such that parts of the film given also the maximum density of 1À8 during exposure will, in the reversed film, be of the desired minimum density. Alternatively, it may be arranged that only part of the unchanged silver bromide, which is left after the first development, is used for the production of the final soundrecord. In such a case, a reduction of the residual silver bromide may be effected by treatment in a fixing bath prior to the second development. In another method, the desired minimum density is produced by controlling the second development or second exposure. In the latter case, a source of light, which, when operated at a voltage of 220 effects the full exposure for a normal reversal process, may be operated at 120 volts so that a minimum density due only to fog is obtained. As applied to variable density recording, the highest density is given only such a value (in any case below 1À8) that after the second exposure the minimum blackening lies so much above the density due to fog that the corresponding value of the transparency still lies on the rectilinear part of the transparency curve. According to a further process, the sound is recorded on photographic layers which have so low a silver content, or are so thin, that the silver halide contained therein suffices only to produce a density of about 1À8 after the first development when the film is exposed throughout the thickness of the photographic layer.
