Abstract: 1535759 Shoe scrapers G S FRODIN and C H WIKLUND 26 Nov 1975 [27 Nov 1974] 48700/75 Heading A4F [Also in Division F4] A grating for use as a ventilation grille or as a shoe-scraper, comprises two tubular posts 2 each having slots 3, slats 1 inserted into the slots 3 to such a depth that a hole 8 in each slat is at least partially located inside the corresponding post 2 to define a through passage along the interior of each post 2 through the respective holes 8, and a respective demountable rod 9 passing through each through passage and being locked with the slats 1 by partial rotation about its longitudinal axis. In the form shown, the slots 3 are inclined obliquely to the longitudinal direction of the posts 2, the holes 8 are circular, and the rods 9 are square, rectangular or rhombic in cross-section. Since each hole 8 is elliptic, so far as the rods 9 are concerned, rotation of the rods 9 by 45 degrees will cause engagement of the rods along the minor axes of the holes 8 either with the holes alone, Fig. 9 (not shown) or with the holes and the posts 2, Fig. 7 (not shown), with consequential deformation of the holes 8, and possibly the rods 9.. Each slat 1 includes recesses 4 which receive the non-slotted portions of the posts 2 and tabs 6 which are received within the posts 2. The posts 2 are provided with end members having holes engaging the rods 9 to hold them in their locked positions. In an alternative embodiment, the slots 3 are perpendicular to the longitudinal direction of the posts 2 and the slats 1 have holes 8 of elliptic or irregular shape.

Title: Method of and means for making articles by dip casting
IPC: B22D25/04
Filed: 1973-10-25
Abstract: 1445144 Casting processes GENERAL MOTORS CORP 25 Oct 1973 [7 Nov 1972] 49721/73 Heading B3F A method of forming thin-sectioned castings, e.g. battery grids, comprises providing a die 2 having a porous metal body 6 having thereon an impervious layer 8 provided with openings leading to a die cavity 4 in said body, passing a cooling gas through the porous body 6 and out through the walls of the cavity 4, immersing the thus prepared die into molten metal 18, applying a vacuum to the proous body 6 to suck the metal into the cavity, removing the die from the melt and shedding any melt metal from the outer surface 10 of the layer 8, and stripping the casting 24 from the cavity. The outer surface 10 is provided with striations (12), Fig. 2, (not shown), defining a plurality of peaks and valleys so that when the die is only shallowly immersed in the melt the metal does not penetrate into the valleys. This results in little, if any, soldification of the melt on the surface 10 and when a thin film of solidified metal does form it does not adhere to the surface but falls back into the melt as indicated at 22. In the embodiment shown, the die 2 is in the form of a rotatable drum and is provided with a stationary air pressure chamber 14 and a stationary vacuum chamber 16. Air from the chamber 14 passes out through the walls of the die cavities 4 to cool the cavities and to eject the castings therefrom. Heaters 20 may be provided to heat the impervious layer 8. The porous body 6 may be formed of sintered bronze and the layer 8 of copper. The lead alloy melt 18 is maintained at a temperature of 650 F.

Abstract: 1,118,710. Rotary regenerative heat exchangers. SVENSKA ROTOR MASKINER A.B. 28 Nov., 1966 [29 Nov., 1965], No. 50526/65. Heading F4K. In a rotary regenerative heat exchanger having a cylindrical rotor 10 containing a regenerative mass and movable within a stationary housing 14 having ducts for the passage of heat exchange fluids, sealing means between the ducts comprises sector plates 20, 22 hinged at their radially inner ends to the stationary housing, and an axial seal 52, the sector plates and axial seal being linked together such that movement of one seal due to thermal distortion of the rotor results in corresponding movement of the others. Links 50 are pivotally attached to the axial seal 52 and to yokes 48 rigidly attached to tubes 46 slidable along rods 44 attached to the sector plates. Lever members 58 are rigidly attached to each link 50 and are pivotally and slidably interconnected by a pin 60 in a slot 62, the lever members transmitting motion from the axial seal 52 to the sector plates 20, 22 and vice versa. A rod 24 attached to the lower sector plate 22 carries a stop (not shown) beneath the upper sector plate 20, which stop defines the minimum separation of the sector plates, and is attached through an adjustable suspension link 36 to one end of a lever 32 pivotally fixed to a link 30 which is pivoted to the housing end wall 28, the other end of the lever being biased by a counterweight 34 or by a spring (not shown) counterbalancing the weight of the sector plates, the axial seal and the linkages. The positions of the yokes 48 and hence of the axial seal 52 are adjustable by means of nuts engaging the outer ends of the rods 44 and a screwthread on the tubes 46. The tubes 46 and rods 44 pass through holes in the housing 14 sealed by bellows-like members 56. In operation, separation of the sector plates 20, 22 due to deformation of the rotor, is transmitted through the rod 24 and links 50 to cause outwardly radial motion of the axial seal 52 in order to decrease frictional contact between the sealing surfaces and the rotor surfaces.
