Title: Improvements in and relating to interferometers for the testing of optical elements
IPC: G01B9/02
Filed: 1928-01-03
Abstract: 305,350. Hasselkus, J. W., and Hay, O. G. Jan. 3, 1928. Interferometers of the kind described in Specification 103,832 are modified so as to be applicable for the testing of optical elements of comparatively large dimensions and are constructed so that errors of movement of one part relatively to another during the test affect both the reference and testing beams in a compensatory manner. The two beams are directed to the testing and reference elements by reflecting surfaces mounted on a common frame or carriage. Light from a suitable source is passed through a diaphragm A and is rendered parallel by the lens B, being incident on a lightly silvered mirror C, the reflected part of the beam passing to the plane mirror D by which it is reflected to a plane reference mirror E normal to its surface so that it is returned to the eyepiece O. The other part of the beam is reflected by the mirror E to the mirror G and thence through the object K under test, e.g. a telescope objective, on to a spherical convex mirror L, the centre of which is coincident with the focus of the object glass under test. This beam is similarly returned, to the eyepiece O. The mirrors D, G are mounted on a common carriage M movable on the frame N so that a radial path is traversed in relation to the objective and any error of movement affects both mirrors equally. A complete survey can be made if the diameter of the mirror L and the length of the reference mirror E is not less than the radius of the objective under test. A planeparallel plate P serves to cause a displacement of the interference bands when necessary. In a modification, Fig. 3, only the mirrors C, F are used being mounted with the eye-piece on a carriage M, as shown. An arrangement of the apparatus is also described by which the convex spherical mirror L may be tested, and consists in adjustably mounting the mirrors D, G on the instrument so that they may be set at an angle whereby the two beams fall normally on the mirror. First the mirrors are arranged so that one beam falls on the central area of the mirror, which is rotated about this beam, testing an annular zone for symmetry, and then the mirror is rotated about the other beam, testing for zonal aberrations.

Title: Improvements in or relating to electric fire alarm systems
IPC: H04M11/04
Filed: 1934-01-04
Abstract: 431,343. Fire-alarm systems. STELJES, W. S., 138, Uxbridge Road, Hampton Hill, Middlesex. Jan. 4, 1934, Nos. 279 and 14819. [Classes 40 (i) and 40 (ii)] A fire-alarm signalling-box is provided with a code transmitter and a phonographic transmitter both of which are released when the alarm is pulled, the signals being given in succession or simultaneously. As shown in Fig. 5 the code transmitter comprises a code wheel 5 normally locked against rotation by a pivoted pawl 36. The wheel is released when a pull-handle is operated to tilt a bellcrank lever and thereby lower a spring-controlled slide 48 carrying a pawl 49 which cooperates with a projection 50 on a pivoted lever 52 to lift the pawl 36 out from engagement with the code wheel. When the pawl 36 is lifted, a pawl 37 which is in advance of the pawl 36 is lowered so as to ensure stoppage of the wheel in case the pull-handle is held operated. The catch 49 also is automatically tripped by a part 54 so as to allow the return of the lever 52 although the pull handle may be maintained operated. The lever 52 is connected by a link 51, Fig. 1, to the release lever 31 of the phonographic apparatus 12, 19. When the link 51 is lowered by the pin 50 upon operation of the pullhandle, the lever 31 is rocked to displace a projection 28b on a spring-controlled pivoted pawl and thereby release the phonograph turntable 12. Simultaneously a further projection is disengaged from a slot in a disc 61 and during rotation of the record rides on the periphery. At the end of the rotation of the record the projection re-engages the slot in disc 61 and thereby allows the pawl to stop the motor and act as a spring buffer thereto. In the arrangement shown, the transmission of the sound signal is effected subsequently with the transmission of the code signal. This is accomplished by a cam 40 which through 41, 21, 20 lowers the pick-up on to the record at the appropriate time during the cycle of operations. After the completion of the sound signal the pick-up is again raised and restored to its normal position by a spring 22. The cam is adjustable so that the timing of the operation of the pick-up may be varied. The radial normal position of the pick-up is also adjustable by an eccentric cam 65. The separate transmitters may be driven independently by spring or electric motors or by a common motor. Further the signals may be transmitted simultaneously instead of successively.

Abstract: 1,207,671. Photo-electric gas analysis. GAS COUNCIL. Jan.4, 1968 [Jan. 4, 1967], No.481/67. Headings G1A and G1B. In determining the sulphur or phosphorus content of a gaseous or vapourized hydrocarbon sample by photo-electrically measuring the intensity of the sulphur or phosphorus characteristic omission when the hydrocarbon is burnt in a hydrogen rich atmosphere, the hydrocarbon is first burnt in an oxygen atmosphere to burn off the hydrocarbons which otherwise when the sample is burnt again at the later measuring stage would quench or obscure the characteristic omission. In Fig.2 a liquid hydrocarbon containing sulphur is pumped with a carrier gas such as hydrogen or nitrogen into a vaporizer 111 and with hydrogen added from line 116 is burnt in an oxygen rich atmosphere in chamber 101. Air or oxygen is fed into the chamber from a ring of jets 121. The combustion products are then burnt at jet 130 in a hydrogen atmosphere added at 123; oxygen for this burning passes to the jet up centre tube 131 from line 132. A photo-multiplier, covered by a filter 139 removing infrared radiation and a filter 140 passing radiation in the band 3400 to 4100 A receives the characteristic omission. The level of intensity may be recorded and an alarm operated if the level exceeds a predetermined limit. A mirror 141 is positioned behind the transparent tube 134. The apparatus may be fed with successive hydrocarbon sulphur compounds from a chromatographic column.
