Abstract: 735,448. Storing organic products. LINDEWALD, T. W. Sept. 24, 1952 [Sept. 24, 1951; Feb. 27, 1952; July 10, 1952], No. 23986/52. Class 49. In storing oxidizable organic products in chambers containing inert gas maintained at pressure greater than atmospheric, the gas is delivered from the chamber, is mixed with an oxidizable gaseous substance and conveyed over an oxidation catalyst for removal of oxygen present in the gas, and is returned to the storage chamber. The oxidizable substance is preferably of such composition that water is formed in the oxidation, and is exemplified by hydrogen or the vapour of pentane or ethanol. Water and other oxidation products may be removed from the gas by adsorption on activated carbon or alumina or by absorption in concentrated sulphuric acid. With the apparatus of Fig. 1, gas is driven by a fan 2 from a storage chamber 1 into a carburetter 4 for admixture with ethanol or pentane, the mixture is passed, in 7, over the oxidation catalyst, and then into a condenser 11 where water and unused ethanol or pentane are condensed, and the gas is returned by a pipe 13 to the chamber 1, the system being maintained constantly at pressure above atmospheric by means of a fan 9 to a branch pipe 8. With the apparatus of Fig. 2, gas from a storage chamber 14 is led through a non-return valve 27 into the lower part of a chimney-like vessel 16, therein past a wick 19 supplied with ethanol or pentane, over a heater 26 and through a layer 20 of oxidation catalyst, is led from the upper part of the vessel 16 to a condenser 22 and liquid separator 23, and is conveyed therefrom by a pipe 25 back to the chamber 14, pressure in the system being maintained by a fan 18, and the thermosiphon flow in the system induced by the heater 26, together with the rate of evaporation from the wick 19, being accelerated or retarded in accordance with the activity of the catalyst.

A gas filtering plant comprises a plurality of preformed chamber units assembled side by side as shown in Fig. 3 and connected together by open frames 3, Fig. 2, each unit comprising a hopper 6 surmounted by a frame having a closed top, front and rear and also at those parts of the sides not engaged by the connecting frames 3, each said frame being partitioned by a closed vertical frame i, k, l, m, Fig. 1, and by a closed horizontal frame n, r, p, o, thereby providing a horizontal conduit bounded by corners n, o, m, e and r, p, l, f, and forming a section of the dust-laden gas inlet duct of the assembly, and providing a vertical filtering compartment bounded by corners m, l, g, h, and i, k, c, d, and also providing a horizontal conduit bounded by corners b, k, p, r, and a, i, o, m and forming a section of the filtered gas outlet duct of the assembly. In operation dust-laden gas from a cupola 15 is drawn by a fan 17 through a main inlet 14 into the inlet compartment of the first chamber unit whereupon a portion of said gas passes downwards through an open valve 1, Fig. 4 into the first hopper 6, then upwardly and through open-bottomed outwardflow filter bags 10 within the filtering compartment, and filtered gas traverses a valved duct 2 connecting the top i, k, c, d of the filtering compartment with the top a, b, k, i of the clean gas duct ; the remainder of the dust-laden gas passing to the inlet ducts of next chamber unit in succession. The filter bags 10 of each unit are cleaned sequentially by known shaking means 11, 13 connected by a link 12 to the valve 1 to close the same and isolate the filtering compartment of the unit being cleaned from the remaining units.

Abstract: 361,372. Cable clamps. MILLER, J. G., The Gables, Trysull, near Wolverhampton, and BULLERS, Ltd., 6, Laurence Pountney Hill, London. Aug. 12, 1930, No. 24173. [Class 36.] A suspension clamp for an overhead cable comprises upper and lower clamping members 19, 13, Figs. 1 and 2, supported by a block 8 bolted between the limbs 4, 5 of a suspension strap 1. The lower face of the clamping member 13 is convexly curved and rests upon a concave face 12 formed on the block 8, the radius of curvature of the concave face 12 preferably being greater than that of the convex face on the lower clamping member 13. To prevent rotation of the block 8, flanges 11 formed on the block are adapted to engage flat surfaces 10 formed on the ends of the limbs 4, 5 of the suspension strap. The lower clamping member 13, which may be formed with troughed extensions 17 having downwardly curved ends 16, is formed on each side of the suspension strap with stops 18 which prevent the withdrawal of the clamping member from the suspension strap. In a modified construction, the block 8 may be formed with a convex face which co-operates with a concave face on the lower clamping member 13. The faces of the block 8 and the clamping member 13 may also be curved about an axis parallel to the cable to permit a lateral oscillation of the clamping members. Figs. 3 and 4 show a similar construction in which excessive pivotal movement between the clamping members and the suspension strap causes the cable to be released. The gripping of the cable is effected by pressure exerted on the upper clamping member 19 by links 30, 31 pivoted together and suspended from a bridge-piece 28 which connects the two troughed extensions 17 of the lower clamping member 13, as shown. The limb 4 of the suspension strap 1 is formed with abutments 33 spaced on either side of the links 30, 31 so that excessive movement between the suspension strap and the clamping members causes flexure of the links 30, 31, and releases the upper clamping member. Complete disengagement of the upper clamping member is prevented by bolts 35.

Abstract: 626,867. Pneumatic springs; road-vehicle spring suspensions. HOUDAILLE-HERSHEY CORPORATION. Aug. 15, 1946, No. 24288. Convention date, Jan. 9. [Classes 108 (ii) and 108 (iii)] [Also in Group XXVI] In a pneumatic suspension device having an electrical control structure comprising electrically conducting sections separated by a dielectric section which is engaged by an electrical contact in the balanced-spring condition of the device, the conducting sections being moved into engagement with the contact on relative movement of the control structure and contact, to complete electrical operating circuits for the control structure in respectively the over-loaded and under-loaded conditions of the device, a pneumatic spring unit is provided including a cylinder member and a piston member co-operatively related, means for supplying, and means for bleeding off, compressed air to and from respectively, the cylinder member, means for controlling the supply means and bleeding-off means, operative in response to energization of the respective electrical operating circuits, the control structure being mounted on one of the members and the contact being carried by the other member. The spring unit comprises a plunger 11 and associated cylinder 9 containing compressed air supplied from a pump (not shown) through a conduit 27. An inner cylinder 37 secured to the base of the cylinder 9 contains liquid and provides a damping action in conjunction with a piston 38 on a piston-rod 43, rigid with the plunger 11. A bellows 29 comprising a series of annular rubber diaphragms 30, united by metal connecting rings 31, 32 provides pneumatic sealing between the plunger 11 and cylinder 9. Supply air through the conduit 27 is controlled by a thermally-responsive pneumatic valve (not shown) in conjunction with an electrical-resistance heating-element which is wired in series with a battery (not shown), a contact 63 on a rod 57 secured to the plunger 11, and a contact 68 in a tubular mounting 61 surrounding the rod 57 and secured to the piston 9. Escape of air from the cylinder 9 is similarly controlled by a second thermally responsive valve in a bleed conduit 28, and associated heater, which is wired in series with the battery, a second contact 64 on the rod 57 spaced from the contact 63 by an insulating portion 65, and the contact 68. As applied to a vehicle suspension the cylinder 9 is secured at its base to an axle while the upper end of the plunger 11 is secured to the vehicle. Operation.-When the plunger 11 and cylinder 9 are in their normal relative position the contact 68 lies adjacent the insulated portion 65 of the rod 57. Under increased load causing relative inward movement, the contacts 63 and 68 complete the circuit through the heater associated with valve in the supply conduit 27, and air is pumped into the cylinder 11 until the contacts 63, 68 separate. Similarly, under decreased loading, engagement of contacts 68, 64 causes air to be released through the bleed conduit 28.
