Title: Improvements in or relating to central heating boilers
IPC: F24H1/32
Filed: 1964-10-16
Abstract: 1,032,499. Hot-water boilers. HUSQVARNA VAPENFABRIKS A.B. Oct.16, 1964 [Oct. 18, 1963], No. 42308/64. Headings F4A and F4B. In a central heating sectional boiler with a fire-box 18 formed by half-sectional castings 12, 13, each of which enclose a water space and have openings 16 and 17 for connecting the water space to the adjoining section and also having a flue-gas collecting channel 20, vertical flues 21 are formed between adjoining sections by flanges 14 and 22 which create a space between the water spaces. Situated in the vertical flues 21 are inserts consisting of pairs of horizontal bars 28 rigidly connected to vertical bars 29 to cause turbulent flow in order to improve the heat transfer from the flue gases to the water. The inserts are removable through an opening 23 and are attached to a cover 24 and may either be made of heat-resistant steel or from ordinary iron, in which latter case they are considered expendable and replaceable, and may be made from solid bars or tubular material. In a modification, the horizontal bars 28 are supported by wires and are adjustable in their angular position within the flues 21. Instead of two rows of inserts a central row of larger horizontal bars can be used which may have oval cross-sections and be controlled by adjusting wires which rotate them and vary the restriction in the flue. In a further modification, the inserts are supported on lugs on the walls of the flues, access being provided in the outer side wall through the flanges 14 and the vertical bar 29 may be dispensed with. The boiler shown is particularly designed for an oil burner which may be situated either on a door at the front of the boiler or vertically near the top of the sections 12, 13. For alternative firing with solid fuel a loose grate 27 can be incorporated.

Abstract: 1,097,393. Ratchet clutches. PLESSEY-UK Ltd. Oct. 23, 1964 [Oct. 28, 1963], No. 42423/63. Heading F2C. Sprags 5, of a oneway clutch, having cylindrical centre portions 8 spaced in cross-bars 9 of a cage 10, are each biased into contact with the clutch races 3, 4 by associated individual pre-tensioned helical torsion energizing springs 17, each having its free ends engaged in holes 18, 19 (Fig. 3), in the associated sprag 5 and cage end plate 12 respectively. The springs 17 are accommodated in closed pockets 17 in the cage plate 12 to prevent broken spring fragments penetrating between and damaging the sprags and/or races. The sprag cylindrical centre portions 8 may engage with clearance, for relative radial sprag movement, similar cylindrically formed edges of the cage cross-bars 9 or, the cross-bars 9 may be formed as plane parallel surfaces to allow the free radial movements of the sprags in operation. A helical oil groove 20 in the bore of the cage produces an hydraulic end thrust between the cage 10 and inner race 4 on relative rotation thereof, whereby locating faces (not shown) on the inner race 4 frictionally rotate the cage with the inner race to prevent wear on overrun.

In an electronic image intensifier, a dynode comprises aligned grids G 1 , G 2  and a secondaryemissive grid G 3  arranged one behind the other and having potentials such that primary electrons reaching the dynode are focused by the electric field between the grids on to the last grid G 3 , the impact surfaces of which are arranged centrally relative to the aperture in grids G 1 , G 2 . As shown, each grid comprises coplanar parallel wires, the distance between grids G 1 , G 2  being of the order of the wire spacing, while the distance between G 2 , G 3  is several times greater. The grids G 2 , G 3  are at the same potential, which may be the potential of the first grid of the preceding dynode, while grid G 1  is at a higher potential, so that secondary electrons produced by electrons incident on the wires of grid G 1  are lost, while the remaining incoming electrons all produce secondary electrons at G 3 , and electrons leaving the dynode have only a small spread of velocities. Each dynode may be made by winding wire around two frames arranged together; detaching the frames from one another to provide two grid parts having parallel wires; removing every second wire from one grid part to form G 1 ; arranging the even-numbered wires of the other grid part in one plane and the odd-numbered wires in another plane, by the insertion of spacers, to form G 2  or G 3 ; and securing the frames together with the desired spacing and with the wires of G 1  and G 2  in alignment.
