A road vehicle wheel is formed with separate rim and hub portions each with radially extending flanges having circumferentially spaced radially extending recesses or projections, the flanges being mutually adjacent to leave an annular gap therebetween which is filled by a rubber or like annulus co-operating with positive means acting axially therethrough, and the recesses or projections to provide respectively, relative axial location of, and driving engagement between, the rim and hub portions. Fig. 1 shows a rim 10 and wheel disc 13 with aligned radial flanges 11b and 14 respectively each embraced by a channel-sectioned rubber ring 18, 17 the bases of which abut each other. The flanges 11b and 14 have aligned radial recesses through which extend bolts 20 clamping together securing rings 19 which embrace the two flanges and deform the rubber rings 18, 17 to fill the recesses in the flanges around the bolts 20. Fig. 4 shows an alternative arrangement wherein a channel-sectioned flange 26 is riveted to the underside of a rim 25 the rivet heads 27a forming projections on the flange base which are aligned on assembly with recesses in the edge of a bowed wheel disc flange 30.

Abstract: 602,706. Gas turbines. GILBERT, A. V. Nov. 9, 1945, No. 30041. [Class 110 (iii)] A gas turbine rotor for use in the propulsion of automobiles is provided with adjustable blades the angle of which relative to the axis of the rotor is adjusted in accordance with the load on the shaft driven by the rotor. A compound gas turbine, Fig. 2, has two independently rotating stages A, B, the first stage A has fixed blades D and is used to drive the compressor of the plant and the second stage B has adjustable blades G and is used to drive the output shaft N. The blades G are rotatably mounted in a bowllike housing B<1> by shafts H attached to bevel pinions K which are engaged by two crown bevel wheels L and M. The wheel M is attached to, and the wheel L is rotatably mounted on, the shaft N. Attached to the wheel M is a disc O also secured to the shaft N and provided with four arcuate recesses P in which are mounted compression springs Q, and attached to wheel L is a disc T with four projections U which fit into the recesses P on one side of the springs Q. Relative rotation of the discs T and O compresses the springs Q. Any relative movement between the discs T and O due to changes in the torque required by the shaft N will cause the crown bevel wheels L and M to rotate the pinions K and adjust the angle of the blades G and thus alter the output of the turbine to suit. Projections on the distance pieces S between the springs Q limit the amount by which the springs Q may be compressed.

Abstract: 1368221 Vehicle headlamp polarizer POLAROID CORP 27 June 1972 [28 June 1971] 30127/72 Heading F4R [Also in Divisions B5 and G2] An attachment 10 for polarizing the light emitted by a vehicle headlamp 12 comprises a circular concave sheet 34 of linear light polarizing material, the sheet 34 including asymmetrically disposed locating means formed integrally with the sheet and disposed adjacent its periphery, e.g. recesses or holes 34, 36, 38, such that the unique polarization azimuth of the polarizer 10 may be located in a predetermined orientation with respect to the emitted beam of light. As shown, the sheet 34 has a spherical curvature and the rim 32 thereof fits between flanges 44 and 56 of a rubber gasket 14 and is mounted on the rim 20 of headlamp 12 by a bezel 16 which fits round the headlamp and has lip 52 engaging the gasket 14. The gasket 14 provides a weather-tight seal and the flange 54 provides an air space between the headlamp and polarizer to insulate the latter from the heat of the headlamp. The polarizer is formed of a laminate comprising a 0À05 mm. thick stretchoriented polyvinyl alcohol sheet between two supporting layers of cellulose acetate butyrate, the total laminate thickness being 0À75 mm. A quater-wave retarding element may be incorporated in the polarizer laminate on the concave side of the polarizing element, this is particularly advantageous when the polarizer is of the multi-laminar interference type. The spherically shaped, recessed or apertured polarizer is made by hot pressing an appropriate planar polarizer laminate using vacuum forming techniques, Fig. 5 (not shown).

[Class 5 (ii).] A method of circulating air in incubators consists in arranging stacks of superimposed trays of eggs in different stages of incubation including eggs in the hatching stage in the same compartment, withdrawing the air from one side of the stacks of trays, mixing the air withdrawn with fresh air and re-introducing the air laterally, under control, into the opposite side of the stack so that the quantity of air admitted is regulated according to whether the eggs are in the incubating or hatching stage. Egg-trays T, having mesh bottoms, are arranged in tiers each comprising three banks of six tray spaces for trays containing eggs in the incubating stage and a bank for hatching trays ; the incubating and hatching trays are separated by horizontal partitions 11 ; otherwise, no horizontal partitions intervene between the various trays. Vertical partitions 13 comprise a plurality of series of apertures corresponding in position with the tray spaces. At the other side, the tray spaces communicate with a central corridor 8 communicating with spaces 14 between the partitions 13 and the incubator walls. A door 7 is provided at one end of the corridor. Fans 17 are mounted over the corridor on beat-insulating boxes 20. Fresh air enters the incubator through a grating 21, passing into a duct in one of the boxes 20 and through apertures 22 into the central corridor; foul air leaves at 23. Below each fan is an electric heater H. The number and sizes of the apertures in the various rows are so arranged that there is an equal flow of air through the incubating trays and a greater flow through the hatching trays. A diffusion of air between the trays containing warmer eggs and those containing cooler eggs is provided for by arranging that trays containing eggs in progressive stages of incubation are separated by trays containing eggs in a different stage ; indicator boards 24 are provided for this purpose ; five stages of incubation are provided for, one tray space in each of the incubating banks being always empty and such space being blanked off by a baffle 25.

On depressing shutter release member 21, lever 10 is moved about its pivot 11 by spring 13, as permitted by the co-acting part of member 21. Electromagnet 27 is responsive to photo-resistor cell 25 so that, at a critical level of illumination of the cell, it releases armature 28 and hook 29 adopts an intercepting position for porjections 46 and 18. When the ambient illumination is below this critical level, the hook 29 intercepts the first projection 46 (as this moves upwardly) and thereby moves pivoted low light signal 41 into the field of view-finder 42 (Fig. 2, not shown). When the ambient illumination is slightly above the critical value, the armature 28 is held upright until mask 16 moves up over cell 25 and reduces its illumination below the critical value. Armature 28 is thus released after the passage of projection 46 and accordingly traps projection 18, as shown, so that lens aperture 20 is not changed. In bright light conditions, the momentary attenuation, as mask 16 crosses cell 25 does not go below the critical value and armature 28 remains upright throughout the movement of lever 10. The movement goes beyond the position shown to align reduced aperture 15 with the lens aperture 20 (Fig. 4, not shown). Sliding contact 24 is also moved about pivot 11 by release 21 and, during its movement over fixed contacts 32, 33 and 34, it momentarily joins all three, to connect a battery directly across the electro-magnet 27. Thereafter, it joins contacts 33 and 34 to connect the cell 25 in series with the magnet 27.
