Title: Improvements in or relating to photocoagulation apparatus
IPC: A61F9/008
Filed: 1965-09-23
Abstract: 1,076,560. Photo-coagulating apparatus. AMERICAN OPTICAL CO. Sept. 23, 1965 [Oct. 16, 1964], No.40550/65. Heading G2J. Photo-coagulating apparatus comprises a first optical system 76, a source of intense light 54 located at the first principal focus of the system 76, field stop means and a second optical system 82 which receives light from the system 76 through the stop means, the systems 76 and 82 being co-operable to form an image of the source at the patient's pupil when the system 82 is arranged in telecentric relation with the pupil of the eye so as to form an image of the stop means 64 on the retina for coagulation thereof. The light source is preferably a laser 44 which is stimulated by a flash tube 48. A series of diffusors 78 carried on a rotatable disc 62 intercept the light beam 54. The field stop means comprises a series of apertures 64.1 in a disc 64 which is synchronously rotatable with the disc 62 so that the appropriate diffusor and aperture may be simultaneously brought into the path of the beam 54. An afocal telescope 84 may be mounted coaxially between the stop 64 and the optical system 82, and axially slidable so as to move the image 140 of the stop 64 in the region of the first principle focus 141 of the system 82 and thus compensate for ametropia in the patient's eye. ' The patient's eye is viewed through an optical system 116 and a semi-reflecting mirror 122. Light from a lamp 102 is projected by means of an optical system 104 and a semi-reflecting mirror 110 on to the optical system 82 so as to illuminate the fundus of the eye. The laser beam is aimed by means of a further lamp 96 from which light passes via an optical system 98 and a semireflecting mirror 100 through the stop 64 and thence to the retina. The laser is then energized by closing a switch in the electrical circuit of the apparatus. A mask 137 located in the path of the beam 54 to provide protection against inadvertent firing of the laser is retracted on actuation of the said switch. Also, on closing the switch a filter 139 is brought across the line of sight of the system 116 in order to protect the surgeon's eyes.

Title: Improvements relating to the testing of catalysts
Inventor: PITKETHLY ROBERT CHALMERS
IPC: B01J23/882
Filed: 1962-10-26
Abstract: 1, 026, 723. Testing catalysts. BRITISH PETROLEUM CO. Ltd., R. C. PITKETHLY, J. F. FORD and A.G.GOBLE. Sept. 25, 1963 [Oct. 26, 1962], No. 40567/62. Heading B1X. The desulphurisation activity of a catalyst of cobalt and molybdenum oxides on alumina is tested by determining the reversible adsorption of an organic monosulphide when a stream of carrier gas containing said sulphide at a partial pressure of below 5 mm. Hg. and below 200‹C., is contacted with said catalyst. By "reversible adsorption" is meant the difference between the total quantity adsorbed and the quantity desorbed when the carrier gas only is passed over the catalyst. The preferred monosulphide is thiacyclopentane and suitable carrier gases are hydrogen and nitrogen. The Figure shows a suitable apparatus for performing the invention: the catalyst sample is placed in sample holder 20, and hydrogen is admitted thereto through line 1, pressure regulator 2, manganous oxide trap 4 (for oxygen) and 4Š molecular seive trap 5 (for water), line 14 and selector valve 13, and after passing over the catalyst is discharged to atmosphere. The furnace 21 is brought up to the testing temperature and the catalyst is thus pretreated. Meanwhile a stream of hydrogen is passed over the monosulphide in a diffusion device 8 and via valve 13 to sampling valve 24 where samples are automatically and repeatedly passed to flame ionisation detector 29 to enable the composition of the stream to be determined, adjustments being made to valve 7 to obtain the correct partial pressure of monosulphide. The stream is then directed by means of valve 13 over the catalyst in holder 20 and the effluent sampled and tested repeatedly until the concentration of monosulphide reaches the original value. Pure hydrogen is then passed over the catalyst and effluent again sampled and tested repeatedly. From the series of results thus obtained the reversible adsorptionwhich is an approximate measure of desulphurisation activity-may be calculated.

Abstract: 1,079,422. Programming arrangements for digital computers. GENERAL PRECISION Inc. Oct. 5, 1964, No. 40601/64. Headings G4A and G4C. A computer system employing a magnetic drum memory is provided with means for " relative addressing " of word sectors on the drum, i.e. for specifying in an instruction word stored in a particular sector the sector address of an operand (or of the next instruction) relative to that particular sector. The instruction to be executed is read out from its main memory channel and rewritten on a circulating register channel (C-channel) with the relative sector addresses counted down by one at each transfer (i.e. at each drum sector time); this is done by selecting the complement output of the read amplifier for the sector address up to the first " one " (starting at the least-significant bit). When the sector address is counted down to zero a control signal is generated for read-out of the operand (or next instruction) from the appropriate track read amplifier. By this means a programme can be written to minimize access time from the drum. The instruction format allows the specifying of the more conventional sector addressing (i.e. from a fixed " start of revolution " point).

Abstract: 973,116. Printed resistors. BTR INDUSTRIES Ltd. Nov. 9, 1962 [Nov. 15, 1961], No. 40924/61. Heading HIS. A group of electrical resistors is produced by fixing a metal foil, carrying on one of its faces a layer of resistance material, to an insulating support, the layer of resistance material being adjacent the support, the foil is then etched away to leave two or more pairs of terminal areas overlapping the resistance material and then the resistance material is removed in part so as to leave discrete areas thereof cooperating with each pair of terminal areas. Fig. 3 shows one embodiment in which terminal areas 16 have been produced by etching away unwanted areas of foil mounted on an insulating base, 15, discrete areas of the resistance material 18 are created by punching out areas of the insulating base carrying the resistance material between the aforesaid discrete areas. Fig. 4 shows an alternative embodiment in which the discrete areas of resistance material are separated by removing the unwanted resistance material by abrasion, as at 20, and in which the resistance value between terminals 16 is increased by punching out areas of resistance coated base to make the path between the terminals tortuous. Reference has been directed by the Comptroller to Specification 690,691.

Such functionally converted sulphonic acid groups may be sulphonic acid chloride, fluoride or bromide groups.  The dyestuffs may belong to a large number of specified vat dyestuff series and as well as the sulphonic acid and acylamino groups may be further substituted with halogen atoms, alkoxy and alkylamino groups and, in certain cases, further hydrophilic, e.g. sulphate, groups.  Especially suitable are a -acylamino, particularly a -aroylamino derivatives which contain the sulphonic acid group or the aroyl group.  The dyestuffs may be applied to regenerated cellulose or cotton in a printing paste or padding liquor (the pad-roll process being suitable for cotton) or advantageously by the exhaustion method in a bath at about 50 DEG C. which preferably contains neutral salt and an alkali.  The reducing agent which may be introduced at any stage of the process may be an alkali metal hydrosulphite, thiourea dioxide or preferably an alkali metal sulphide or hydrosulphide or glucose.  Instead of preparing a dyebath the vattable compound, reducing agent and, if desired, neutral salt may be made up into a stiff paste or dry preparation. In the examples a large variety of dyeing, printing and padding processes are described employing a large number of dyestuffs.
