Title: Improvements in and relating to colour analysers
IPC: G01J3/42

Abstract: 404,065. Recording colour values. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Stone, C. W.; Box 985, Schenectady, New York, U.S.A.) Aug. 10, 1932, No. 22425. Convention date, Aug. 10, 1931. [Class 97 (i).] Apparatus for recording colour values comprises a light source, means for dispersing a beam therefrom to produce a spectrum each band of which successively illuminates simultaneously both a standard and a test sample, a photo-electric device receiving light in alternation fron the standard and sample, and recording means responsive to the output from the photo-electric device. The Figure shows a lamp 1 directing a beam through a slit 3 on to a dispersing prism 4 ; a prism 6 receives a colour band of the spectrum produced and reflects it both on to the sample 7 and the standard 8. Light from the sample and from the standard is transmitted by rotating polarisers 13, 19, fixed polarisers 14, 20, and fixed prisms 15, 21, to a photo-electric cell 16. The polarisers 13, 19 are rotated through gearing by a synchronous motor 25, and the polarising apparatus is arranged so that, when one beam is passing to the cell 16, the other is cut-off, and viceversa, in a definite phase relation to the supply circuit. The motor 25 also rotates a record drum 40 through worm gearing 43, and rocks the prism 4 through a cam 44, links 45, 46, and shaft 5, the rocking of the prism 4 causing the complete spectrum to pass over the prism 6 during a half revolution of the drum. If the intensities of the light reaching the cell 16 from the sample and standard respectively are different, the current impulses from the cell, passed through an amplifier 30, and transformer 31, energize the field winding 32 of a reversible motor 33. The shaft 34 of the motor armature carries a worm 35 operating through a worm wheel 37 to adjust a diaphragm 17 to equalize the light intensities reaching the cell, and also, through a screw 36, moves a nut 38 carrying a pen or pencil, to make a record of the adjustment on a sheet carried by the drum 40. Specification 341,200 is referred to.

The powder is used in a trap comprising an earthenware basin made with slanting surfaces a from which a round glazed curve b leads into the catching space of the trap; the curve b is treated with the powder which is also strewn over the catch space. A central bait receptacle g is filled with bait f and its upper portion may serve as a spittoon i. A rough porous covering z may be fitted to the exterior of the trap and may be supplied with water from a hollow space d in the outer wall by wicks e. In a modification the bait receptacle is raised above the catch space. The powders may be mixed with water or sticky liquids, particularly with water glass. In the Specification as open to inspection under Sect. 91 the immobilizing powder is described as being contained in receptacles surrounding the supports of perches, bird's nests and also around the legs of furniture.

Filed: 1922-08-18
Abstract: 202,839. Lembeke, C. C. H., and Poths, F. J. Aug. 18, 1922. Riveting.-Relates to holders-up and comprises a construction in two parts separated by a spring which can be compressed by a lever-actuated cam so that the two parts have a metal-to-metal contact when the riveting operation is started. As the head of the rivet cools and contracts, however, the two parts are separated by the spring so that during the later part of the riveting operation the resistance is an elastic one. In the device shown the die 13 for the rivet head is held in the tubular upper end of a part 7 in which is a diaphragm 10 separating the bores 8, 9. In the bore 8 is the upper end of a spindle 1, which is slotted at 2 and has a telescopic extension 28 engaging the abutment 30. The lower end of the part 7 is flanged outwardly at 7a and surrounding it is a sleeve 4 to which is screwed a ring 5 carrying a crossbar 3 passing through the slot 2. Pivoted in the. slot is a cam 14 having a lower extension 17 provided with a spring pawl 20 which engages a toothed segment on the spindle 1 to lock the cam in any desired position. After the rivet has been inserted the cam is rotated to place the parts in the positions shown in Fig. 2 in which the flange 7<a> abuts on the ring 5 to give a solid hold-up. As the rivet-head cools and contracts the parts 7<a> and 5 are separated by the spring 12 so that the hold-up is a yielding one during the finish of the riveting operation.
