Title: Improvements in corner blocks for connecting or reinforcing adjoining wood surfaces and method of producing said improved corner blocks
IPC: F16B12/04
Filed: 1939-02-13
Abstract: 524,965. Furniture joints. LAMMERMANN, H. Feb. 13, 1939, No. 4719. Drawings to Specification. [Class 52 (ii)] [Also in Group XXIII] Corner blocks for connecting or reinforcing adjoining wood surfaces at an angle to one another comprise a number of thin layers of wood of equal curvature glued together face to face and with the grain extending substantially in the line of curvature of the layers while the convexly curved side of the block faces the apex of the corner formed by the wood surface to be joined. The blocks are cut from a slade of wood made up of superposed and glued layers of equal curvature and the equal curvature is obtained by impression in inflexible equally curved halves of a pressure mould during the glueing of the layers.
Patent GB-682369-A (GB)
Title: Improvements in or relating to optical aligning instruments
IPC: G01B11/27
Filed: 1951-02-27
Abstract: 682,369. Optical apparatus. KODAK, Ltd. Feb. 27, 1951 [March 7, 1950], No. 4721/51. Class 97 (i). An optical aligning instrument comprises an objective forming an image of a test object, means for viewing the image, and optically between the objective and the viewing means, semi-transparent plane reflector means for doubling the image in two azimuths. The reflector means may comprise a single reflector with its plane substantially in the optic axes and rotatable about such axis, or two fixed plane reflectors, the line of intersection of which substantially coincides with the optic axes. Fig. 1 shows the principle of the invention. A lens 12 forms an image 13 of an object 11 viewed through a lens 14. A semi-transparent reflector 16 intercepts some of the light to form a second image 20 inverted relative to the first and inclined thereto according to the inclination of the plane 17 of the mirror. The point of intersection 21 of these images is the point on the object 11 at which it is intersected by the plane 17, whereby the alignment of the instrument and object can be checked. The mirror may lie in the optic axis when the two images will be parallel, rotation of the mirror about the axis enabling doubling of the image to be effected in a number of azimuths. The mirror 16 may be between the lens 12 and the lens 14 and may be replaced by a transparent block 31, Fig. 5, having plane parallel end walls 35, 36 and two orthogonal internal semi-reflecting surfaces 32, 33 the line of intersection of which is placed on or adjacent the optic axes. Four images of the object are seen, Fig. 8, and, with the line of intersection of the mirrors 32, 32 on the optic axes, when the object or instrument is adjusted until all the images coincide at the centre 45 of the field, the axis of the instrument will be aligned with the centre of the object. Fig. 10 shows a modification in which the objective comprises a concave spherical mirror 66 and meniscus correcting lens 67 the latter carrying a plane mirror 68 to form an image at 69, at which point is located the quadruple mirror of Fig. 5, or a rotatable plane mirror, the resulting images being viewed in a microscope 71, 72. Small adjustments of the optical axis may be effected by adjustment of a plane-parallel plate 85 mounted for rotation about a horizontal axes 88 in a ring 86 adjustable about a vertical axis by a knob 87. A wide angle telescope may be incorporated in the system to assist initial alignment on the object. This comprises an objective 79 cemented to a Dove prism 76 on the lens 67, which mirror reflects light to a fold lens 80 with a graticule, which is observed in an eye-piece 77.

Abstract: 684,814. Change-speed gearing. STOECKICHT, W. G. Feb. 27, 1951 [Aug. 30, 1950] , No. 4726/51. Class 80 (ii). A change-speed gear giving two forward and one reverse speeds comprises two epicyclic gear sets, the annulus 6 of the first set being coupled to the engine shaft 4, the carrier 13 of the second set constituting the driven member of the double gear, the carrier 8 of the first set being coupled to the annulus 11. of the second set and the two suns 9, 14 being formed on a common sleeve 15. Reduced forward speed is obtained by applying a brake 24 to the member 15, direct drive by engaging a fluid-actuated clutch 26 between the annulus 6 and the carrier 13, and reduced reverse drive by applying a brake 23 to the carrier 8. As shown, the carrier 13 drives the final driven shaft 20 through an additional epicyclic. gear of which the annulus 18 is coupled to the carrier 13, carrier 19 is integral with shaft 20, a brake 25 being adapted to be applied to sun 22 or a fluid-actuated clutch 27 engaged between sun 22 and carrier 19 so as to afford two additional reduced forward speeds. Alternatively, the additional gear set 18, 19, 22 may be arranged ahead of the double gear set and may be replaced by a hydraulic torque converter.

Class 23 In a multi-cell cyclone separator comprising a primary separator having cells of the straight flow type and a secondary separator having cells of the return flow type, all the dust discharged from the primary separator is led by a duct to the secondary separator, and the clean gas from the secondary separator is withdrawn by a suction fan. Gas to be cleaned from a duct. 10 passes through the primary cells 11 which discharge clean gas into a duct 16. The dust discharged from slots 19 in the primary cells is led by the duct 29 to the inlets 23 of the secondary cells 22. All the separated dust is discharged from the secondary cells to a hopper 32. The clean gas from the secondary cells is discharged into the ducts 10 or 16 by the fan 31. The separator may be provided with a central partition 47 and dampers 45, 46 so that part of the separator may be isolated whilst the other part is operated. Inspection doors may be provided at A, B, C. In a modification Figs. 9, 10 (not shown), the separator is arranged between vertical ducts in which the gas flows downwardly. The cells are arranged vertically, groups formed by double rows of primary cells being interspaced by groups formed by double rows of secondary cells placed at lower, level. The dust is discharged from each group of secondary cells by hoppers which project through the wall of the clean gas duct. In a further modification, Figs. 11, 12 (not shown), the separator is arranged for upward gas flow. Groups formed by single rows of primary cells are interspaced by groups formed by single rows of secondary cells placed at the same level. The dust is discharged by hoppers which project through the walls of the dust laden gas supply duct.
