Patent GB-1090139-A (GB)
Title: Refrigerant drier
Inventor: GRUBER WALTER
IPC: F25B43/00
Filed: 1966-08-16
Abstract: <PICT:1090139/C1/1> A desiccant block 6 for use in refrigerant circuits having broader end 6b rests on washer 9 in a container 1 having inlet 3 and outlet 4.  A cavity in the block is filled with a loose desiccant 7 and is covered with material 6a, plate 10 being kept in place by spring 8.  Refrigerant passes round the side of the plate 10 and passes into the block from the sides and out at the bottom.  In Fig. 2 (not shown), instead of plate 10, the space round the sides of the block and on top are filled with additional desiccant (11), the whole being covered by perforated plate (12), held in position by spring 8.  Preferred desiccants are silica gel for the block 6, this being compacted with a binder, a molecular sieve for 7 and active carbon or alumina for (11).  The material (11) is said to prevent oil sludge, oil carbon, and acids from coming into contact with the main adsorber.  The whole is said to have a filtering as well as adsorbing action.  The binder may be a thermosetting resin which is initially liquid and then polymerized after addition to the drying agent, or else a solution of a suitable resin.  The cover-plate 6a may have the same composition as the block, and may likewise be applied to the top of the block in unpolymerized condition.

Title: Improvements in or relating to apparatus for controlling the rate of discharge of coal slurry to the hearth of a blast furnace
IPC: C21B5/00
Filed: 1966-08-17
Abstract: 1,109,947. Controlling burners. BAILEY METER CO. 17 Aug., 1966 [17 Aug., 1965], No. 36750/66. Heading F4T. In a burner arrangement for discharging a coal slurry into a blast furnace, coal slurry is conveyed via a pipe 21, shut off valve 23, a magnetic flow transmitter 29 and pipe 31 to an aspirator 17 supplied with a fluid such as air for controlling the slurry via a pipe 33 and control valve 35. The aspirator 17 extends along a tuyere 11 which is supplied with a blast gas such as air via a pipe 15. The rate of flow of fuel to each tuyere is regulated by a signal from a hand loader 47 which generates a signal corresponding to the desired rate of flow of the slurry. The signal is transmitted to a bias selector station 51 by means of which the signal may be biased to vary the rate of flow of slurry to one tuyere relative to another.

Abstract: 1,166,461. Fuel injection systems. RICARDO& CO. ENGS. (1927) Ltd. Oct. 18, 1966 [Aug. 26, 1965], No. 36820/65. Heading F1B. Fuel is initially supplied to the pressure chamber 11 at reduced pressure by a pressure reduction valve 27 which has associated therewith means for by-passing the valve at higher delivery rates. The fuel from an injector pump is supplied to passage 23 and initially flows through port 21 and passage 36 at a reduced pressure controlled by the spring-loaded plunger 27 to a piston 32, which is thereby forced to the left to cause a pilot injection at a slow rate determined by orifice 35. When piston 32 opens ports 22, 25, the plunger 27 is by-passed and the fuel flows through passage 26 at full delivery pressure. In a modification the restriction 35 is arranged between plunger 27 and piston 32. In Figs. 3 and 4 the pressure reducing plunger 49 is rotatable from an idling position as shown in Fig. 3, in which slots 50 are out of register with main delivery port 44 and all the fuel passes at reduced pressure through orifice 41, to a normal operating position in which the slots 50 interconnect the ports 42, 44, and the fuel is delivered at full pressure through passage 43. The plunger 39 is rotated by linkage 60...62, Fig. 4, operated from the pedal 54 controlling the fuel pump governor load spring 57.

Drawings to Specification. [Class 41] In the three-layer method of refining aluminium from aluminium alloy scrap, scrap is added to the anodic layer in excess of the quantity of alloy treated corresponding to the quantity of refined metal produced at the cathode such that as a result of the progressive increase of its depth, the anodic layer preserves a content of the heavy constituent (e.g. copper or zinc) lower than the value (40 per cent for Cu) incompatible with the purity of the refined aluminium. The initial depth of the anodic layer may be the minimum depth through which the alloy to be treated will sufficiently rapidly diffuse during the recharging step and the increase in depth of the anodic layer during the working of the cell may be equal to the depth of the electrolyte layer. The anodic alloy may be renewed by drawing off a portion thereof and diluting, as regards the heavy constituent (e.g. Cu or Zn), the remaining portion by the addition of alloy to be treated. Arrangements are provided for lifting the cathode block making contact with the refined aluminium as the bottom layer of alloy and hence the layer of refined aluminium rises and comprise a crank-wheel for lifting a rod supporting the block. Specification 405,596 is referred to.
