Title: Improvements in or relating to sight-testing apparatus
IPC: A61B3/028
Filed: 1932-07-04
Abstract: 402,516. Sight-testing apparatus. PULZER, L. S., STEARMAN, S. R., 45, Hatton Garden, London, and MAXWELL, E. H., 472, London Road, Croydon. July 4, 1932, No. 18911. [Class 97 (i).] In apparatus of the kind in which two lens holders, one carrying a set of positive lenses and the other a set of negative lenses, are so mounted on a frame that the positive and negative lenses can be placed in succession independently of one another into the field of vision by adjusting the holders, the negative lens holder is arranged to carry as many or substantially as many lenses as the positive lens holder carries. The apparatus comprises two similar casings, one for each eye, each containing a set of positive and a set of negative lenses, and each having an aperture in the field of vision. As shown, the negative lens carrier comprises two discs 15, 16 mounted co-axially on a plate 19 which is connected by spacing members to the main frame plate 18 having an aperture 20 in the field of vision. Each disc 15, 16 has six apertures which can be brought successively by rotation of the disc into register with the aperture 20, five of these apertures carrying negative lenses and the sixth being blank. The disc 16 is freely mounted on the hub 33 of the disc 15 which is provided with a toothed rim gearing with an idle pinion 47 which can be rotated by a toothed wheel 48 secured to a spindle 49 having an actuating knob 50. Secured to the disc 15 is a wheel 52 having a single tooth 53 which engages once in each revolution of the disc 15 with a star wheel 55 fast with a toothed wheel 57 meshing with a toothed wheel 58 secured to the disc 16 so that the disc 16 turns through one-sixth of a revolution for each revolution of the disc 15 ; thus all the lenses in the disc 15 can be brought in turn into register with each lens of the disc 16 and with the aperture 20. The lenses in the disc 15 may have powers of -À25, -À5, -À75,- 1, and - 1À25 D, while those in the disc 16 may be - 1À5, - 3, - 4À5, - 6, and - 7À5 so that all powers from -À25 to -8À75 D by steps of -À25 can be obtained. An auxiliary lens of - 9 D may be pivoted to the casing so that it can be brought into the field of vision when required to enable powers from - 9 D to - 17À75 D to be obtained. The power of the lens or lenses in the field of vision is indicated by graduated discs 62, 61, the disc 62 being secured to the spindle 49 and of such diameter that it turns through 90‹ for each step of the disc 15. This disc bears the graduations 0, À25, À50, and À75 while the disc 61 bears the whole numbers from 0 to 8 and is intermittently rotated by the disc 62 by gearing similar to that described above so as to turn through one ninth of a revolution for each revolution of the disc 62. The disc 61 has gaps through which the numbers on the disc 62 can be read and both sets of numbers are observed through a window 63.

Title: Chemical ignition system
IPC: C06C9/00
Filed: 1973-04-19
Abstract: 1432621 Igniters RONSON CORP 19 April 1973 [27 April 1972] 19189/73 Heading F4F A method of igniting a gas in an ignition space comprises releasing into the gas in the space, quantities of aluminium borohydride and an ignition aid which is either methanol or acetaldehyde to form a reactive mixture which ignites the gas. An igniter, Fig. 1, comprises an outer cartridge 13 having a tapered part 14 in one end wall. An inner cartridge 15 reciprocable within cartridge 13 contains a hollow plunger 21 containing absorbent material saturated with aluminium borohydride, the plunger having an end closed by a cap 24 having a tip 27 adapted to seal an orifice 13a in cartridge 15. A spring 20 acts between a shoulder 22 on plunger 21 and a seal retainer 18 which may be integral with an end cap 17 of cartridge 15. Cartridge 13 is sealed by a cap 28 and seal retainer 31 to which is secured a rod 30 and one end of a spring 33. An absorbent cylinder 31 is saturated with the ignition aid. In use a blow on cartridge 13 adjacent orifice 14 or sharp acceleration/deceleration thereof, causes plunger 21 and cartridge 15 to move rearwardly. Cartridge 15 moves against spring 33 until end cap 17 strikes rod 30 and a space is provided between cartridge 15 and sealing gasket 34 for passage of the ignition aid to port 14. Plunger 21 continues to move towards cap 17 thereby opening port 13a for passage of aluminium borohydride through port 13a to port 14. In Fig. 2 a lighter comprises two cartridges (47, 48) containing aluminium borohydride and ignition aid respectively, movable within housing 35 and surrounded by springs 51, 52. A finger piece 36 is pivotable against the action of spring 38 to move a striker plate 41 into contact with the cartridges thereby moving them inwardly, the plate pivoting about pin 42 until it abuts stop 44 and flanges 53, 54 on the cartridges are freed from the plate 41. The cartridges then impact against a pin 55 to discharge some of their contents towards a baffle 57 located adjacent a burner valve 62 communicating with a fuel gas reservoir 60. Reference has been directed by the Comptroller to Specifications 1,249,101, 1,107,609.

Abstract: 748,788. Luminescent materials; discharge lamps. GENERAL ELECTRIC CO., Ltd., and McKEAG, A. H. July 12, 1954 [July 17, 1953], No. 19855/53. Class 39 (1). A neon filled discharge lamp includes titanium activated calcium magnesium meta-silicate with or without zinc silicate which luminesces under the very short U.V. radiation 736 Š from the neon discharge. The silicate contains calcium oxide and magnesium oxide in equimolecular proportions and is represented by the formula CaO.MgO.2SiO 2 . The titanium is present in the range of 0.01 to 10 per cent, preferably 0.1 to 1 per cent, by weight of the luminescent material. The luminescent material is prepared by mixing the oxides of calcium, magnesium, silicon and titanium, or compounds producing the oxides on heating, and heating the mixture in steam or in a restricted amount of air in a closed vessel at a temperature in the range 1100‹-1350‹ C., preferably 1250 ‹ C. for one hour. Five per cent by weight, preferably 2.5 per cent, of a flux such as calcium chloride and/or calcium sulphate can be used. The material can be mixed with one or more other luminescent materials such as willemite in such proportions as to produce luminescence of colours varying from yellow, through white to pink. The lamp has a tubular envelope so constructed that the current density of the discharge in normal operation is 5-40 milliamps per sq. cm. and the internal diameter of the envelope is from 10-10 mm. In one example the envelope is 20 mm. in diameter and is operated with a current of 60 milliamps. The pressure of the neon filling at room temperature is 2-15 mm., preferably 5 mm. Specification 457,486 is referred to.
