Patent GB-1064911-A (GB)
Title: Improvements in or relating to magnetic recording and reproducing apparatus
IPC: G11B17/02
Filed: 1965-02-18
Abstract: 1,064,911. Magnetic disc recording &c. apparatus. AMPEX CORPORATION. Feb. 18, 1965 [April 2, 1964], No. 7053/65. Heading G5R.  Magnetic disc recording/playback apparatus comprises a turntable for rotating the disc 19, and means driven by the turntable for moving a transducer 131 radially along a guide 121 so that the transducer describes a spiral path along the disc. The disc is provided with a central hole 31 for engaging the turntable spindle and  with a locating slot 21 to ensure that the transducer always starts at the same point on the circumference of the disc. The record is inserted through a slot 51 in the casing and its insertion actuates a switch arm- 321 and a further switch (not shown) when it is centred on the turntable. These switches energize a solenoid 421 which allows a locating rod (101, not-shown in Fig. 1) to drop through the hole 21 in the rotating record and stop it in a reference position. The operator then presses a start button which energizes a further solenoid (461) which rotates a shaft 491, thereby withdrawing the locating rod, depressing a clamping member 111 on to the disc and the turntable, and lowering the guide 121 so that the transducer contacts the record. The transducer can be adjusted relative to the guide, Figs. 8-10 (not shown), and the pressure can be adjusted by means of a screw (284, Fig. 5, not shown) which controls the height of the turntable. The transducer is driven radially from the clamping member 111 via a clutch, a worm drive and a belt which is preferably of the same material as the record disc. When it reaches its limit position it operates a switch to turn off the apparatus. Alternatively, when recording a 30-cycle signal is recorded after the end of a message, and on playback the 30- cycle signal causes the apparatus to be turned off. Two machines may be coupled together so that when one stops the other starts. A cam (773) driven from the transducer drive transmission may switch capacitors (862) successively into the transducer circuit to equalize the frequency response as the head moves across the record. When a record-play switch is moved to the record position a warning light comes on, and recording will not start until a second manually operated switch is closed. The output circuit from the transducer passes through a muting switch which is opened when the shaft 491 rotates to the inoperative position

Title: Improvements in or relating to photographic sensitive materials
Inventor: DIMSDALE WILFRID HAMPDEN
IPC: G03C7/28
Filed: 1956-03-07
Abstract: 799,835. Photographic and radiographic materials. ILFORD, Ltd. Jan. 9, 1957 [March 7, 1956], No. 7215/56. Classes 98(1) and 98(2) A sheet support has a layer dyed black with a silver-dye-bleach dye or dyes and superimposed directly thereon a layer of silver halide emulsion. A further black dyed layer which is opaque to subdued light may be added and both sides of the support may carry either the two or three layers. The invention reduces the coating weight of silver required for a given contrast, the usual coating weight thus giving a very high contrast. The sub-coating of dye reduces halation and controls scattered light from radiographic intensifying screens. In an example, a gelatine solution containing a mixture of cyan, yellow and magenta silver-dye-bleach dyes is coated on a subbed film base and a silver iodobromide emulsion is coated on the dye layer. The exposed material is processed as in the silver-dye-bleach process using a bleach bath containing thio urea, citric acid and anthraquinone Z sulphonic acid. Specifications 133,034 [Class 98(ii),], 397,159, 397,188, 418,368 and 711,232 [Group IV(c)] are referred to.
