Abstract: 1,228,591. Photo-sensitive materials for printing plates. POLYCHROME CORP. March 3, 1969 [March 14, 1968], No.12479/68. Heading G2C. A photo-sensitive material for use in producing printing plates comprises a transparent support having a surface which is either hydrophilic or rendered hydrophilic during processing coated with a light-sensitive layer which on exposure and processing produces a positive-working lithographic plate and coated on the other side of the support a layer which after processing contains a positive silver image said layer being (a) a silver halide emulsion layer (b) an image-receiving layer used in a silver salt diffusion transfer process or (c) a layer comprising a photo-sensitive or photoconductive compound which after exposure may be physically developed in the presence of a silver salt to yield a positive silver image. Specified positive-working light-sensitive layers are naphtho- or benzo-quinone diazide sulphonic or carboxylic acid amides or esters, a condensation product of a phenol-formaldehyde resin with a naphtho-quinone diazide as in Specification 1, 204,496, a diazo resin treated with potassium ferrocyanide as in Specification 947, 760, a novolak resin and a diazonium salt as in Specification 944, 884 or a novolak resin with a diazonium reinekate salt as in Specification 1,080,153.

Alternatively, photo-sensitive compounds which on exposure and physical development produce a silver image disclosed in Specifications 1, 064, 095 and 1, 076, 779 may be used. In the examples, a polyester support is coated on one side with polyvinyl alcohol layer which is either cross-linked or insolubilized by heating and this layer may contain silica and then coated with a diazide resin. The support is coated on the other side with gelatine and then with a high contrast silver halide emulsion which is imagewise exposed and developed. The silver image is bleached out with an acidic dichromate bath, the material fogged by exposure to light and the latent image produced developed to give a reversal, positive silver image. The diazide resin layer is now exposed to ultraviolet light through the silver image and developed to produce a positive printing plate. Alternatively, the support may be rubbed on both sides with cellulose acetate which is surface hydrolyzed on one side to which the silver halide emulsion is applied. After exposure and development of the diazide resin, the bared cellulose acetate is surface hydrolyzed to produce a lithographic plate.

Abstract: 1,228,701. Frequency syntherisers; signal generators. GENERAL RADIO CO. 1 Jan., 1969 [31 May, 1968], No. 87/69. Heading H3F, H4L. The invention relates to a frequency-synthesizing arrangement of the "add-and -divide" type; i.e. in which a first frequency #C 1  (e.g. 5 MHz) is added in a mixer 1 to the output of a source of fixed standard frequency F (e.g. 42 MHz) and the sum frequency (47 MHz) extracted by a filter 47. This is then added in a second mixer 3 to the output of a switchable source of digit selecting standard frequencies 2 (e.g. 3-3.9 MHz), the sum frequency (50-50.9  MHz) extracted by a filter and applied to a divide-by-ten circuit 4. The output of this comprises a frequency #c 2  (within the range 5À0- 5.09 MHz) based on the first frequency #c 1  and to which the process is again applied, using mixers 1<SP>1</SP>, 3<SP>1</SP> and divider 4<SP>1</SP> to obtain the frequency #c 3  (within the range 5.0 to 5.099 MHz). The process may be repeated as many times as desired to give descending orders of variable digits. According to the invention, switches S1 S2 &c. are provided and permit the replacement, in any stage of the synthesizer, of the fixed standard frequency F by a swept frequency F##. The swept and fixed standard frequencies are compared in a subtracting mixer 12, followed by low-pass filter 13, the output of which comprises a marker signal whenever the swept and fixed standard frequencies coincide. Side marker frequencies can also be generated by means of side-marker generator 6, the output of which is compared in a subtraction mixer 14 with the output of mixer 12, marker output being obtained over low-pass filter 15.

Abstract: 1,229,094. Atomic absorption spectrophotometer. COMMISSARIAT A L'ENERGIE ATOMIQUE. Sept. 19, 1969 [Oct. 1, 1968], No.46385/69. Heading G1A. An installation for atomic absorption spectrophotometry for the analysis of radio-active solutions, comprises a chamber 17 having a burner 1 and a device for spraying into the flame a solution containing an element to be determined said burner being supplied with combustion gases from cylinders 6 and 7. Light from a discharge tube 22 having a cathode formed of the same element is shone through windows 21 and the flame into a spectrometer 24 for measurement of the atomic absorption. The gases and vapours produced are removed by duct 28 having a high power extractor fan 30 such that the gases and vapours are passed through a bubbling column 31 containing dilute sulphuric acid and fitted with Raschig rings, through cooling coil 36 and two filters 38 and 39 into a second column 42 for bubbling through sodium hydroxide and thence via extractor fan 30 and duct extremity 29 into the atmosphere. Further cooling of the gases is effected by a stream of air, circulated through the vacuum tight chambers 17 towards duct 28 and from a closure member having an elastic sleeve 44, placed in the chamber wall so as to open under the action of the reduced pressure produced by extractor fan 30. The radioactive wastes produced can be removed by means of extractor valve 35. Safety devices are included for monitoring the flame and measuring the rate of flow and temperature of the gases.

Abstract: 1,229,152. Magnetic storage arrangements. BURROUGHS CORP. 22 Jan., 1969 [1 Feb., 1968], No. 3542/69. Heading H3B. Writing and reading of data in a magnetic store is effected by the passage of a domain wall along a magnetic plate. As shown in Fig. 14, data is stored in a removable memory board 14-26 consisting of an anisotropic magnetic film deposited on a glass plate 14-20 which is bonded to a copper write/sense ground plane 14-32, a thin glass epoxy sheet overlying the assembly. The travelling domain wall is produced in an adjacent magnetic plate 14-42 which is capped by a silver drive winding 14-48 and has a zig-zag winding 14-40 on its lower surface. The drive winding 14-48 is in electrical contact with an electro-deposited copper secondary winding 14-46, and the winding s together enclose a silicon-rubber encased primary drive winding 14-60 and a pair of transformer laminations 14-44. The assembly includes write/sense lines 14-30, and is surrounded by a bias winding 14-12, pairs of such assemblies being mounted on opposite sides of a support sheet 14-10, Fig. 12 (not shown). Domain wall propagation by nucleations is effected by A.C. in primary winding 14-60 which is coupled to the closed secondary path 14-46, 14-48, the secondary winding path additionally acting as an eddy current shield for forming a domain wall field of a shape suitable to influence the magnetic storage film. The bias winding is used to switch the storage film towards the hard direction during writing. Detection of the spatial position of the domain wall during propagation is effected by the zigzag winding. The writing and reading circuitry for groups of memory assemblies in a memory stack frame 1-10 is shown in Fig. 1. A drive matrix 1-16, a bias matrix 1-12, a nucleation matrix 1-20 and an information matrix 1-26 are provided for the selection and control of a particular group of memory assemblies identified by an address register 1-38. Drives are provided by a drive generator 1-30, a bias generator 1-14, a nucleation generator 1-36 and an information driver 1-42, the latter driver being controlled by an information register 1-58 through a gate 1-56 and a write strobe gate 1-60. Domain wall propagation by the drive and nucleation generators is controlled by a timing and control circuit 1-32, the correct spatial position of the wall being maintained by the output from a zig-zag winding amplifier 1-28 which adjusts a phase compensator 1-34 in the drive generator control circuit and at the same time activates a strobe generator delay 1-46. For writing information from an information register into a particular address identified by the address register, the write strobe gate is controlled by a lead-in timing and control 1-52. For reading, a sense preamplifier 1-22 couples the sense line outputs to a sense matrix 1-24, the output signals from the sense matrix being applied through sense amplifiers 1-40 and a delay 1- 48 to a read strobe gate 1-50. A suction system is provided for holding the memory boards adjacent the travelling domain wall assembly.

Abstract: 1,230,903. Foam generators. G. ROTVAND. 15 July, 1969 [22 April, 1969], No. 35613/69. Heading B1C. [Also in Division A5] A fire foam generator has a mixing conduit 1 with at least two parallel sides (e.g. it may be of rectangular cross-section), a feed chamber 4 for foam-forming liquid with nozzles 6 arranged to produce jets which impinge on each other and on the walls of the conduit, and an air inlet 7. As shown the generator is mounted vertically on a support 9 on the well 10 of an oil tank having a floating cover 13, and has a downwardly curved outlet spout 11 (see also Figs. 7, 8 and 9, not shown). The feed chamber 4 may also be flat-sided (see Figs. 5, 7 and 9, not shown) and the conduit may be arranged as a tortuous passage to increase turbulence and shorten the generator (see Fig. 10, not shown). The wider walls of the conduit may be curved transversely to mate with the side walls of a cylindrical tank; it may be of trapezoidal cross-section, have rounded narrow wells, corrugated side walls, or be divergent or convergent (see respectively Figs. 11, 12, 13, 14, 15 and 16, not shown). There may be screens in the conduit to promote foam formation. In a modification, Fig. 17, a generator 40 for normal foam having a side air inlet is mounted on top of a fine foam generator 43 (having screens or other devices, not depicted) which is open to atmosphere at the inlet end and has four diverging jets 45 supported by a spider 44, whereby normal or finely-developed foam or a mixture may be supplied.
