Title: Improvements in or relating to infusion equipment for shot-firing
Inventor: POTTER JOHN JAMES
IPC: E21C37/12
Filed: 1958-08-15
Abstract: 853,272. Fluid pressure blasting devices. HAYDEN-NILOS Ltd. July 10, 1959 [Aug. 15, 1958], No. 26243/58. Class 9(1). An infusion tube is provided with a relief valve operated by lengthwise movement of an end of a tubular expansible seal on the tube and limiting the pressure inside the tube and consequently the amount by which the seal may be inflated. The seal 30 of rubber tubing is clamped at one end 31 to a groove 28 in an extension 11 of the tube 12 and at the other end to a valve collar 23 slideable on a stem 19 projecting from the extension 11. In operation water is pumped through a cross passage 16 connecting the inner end of the blind bore 14 and the cylindrical periphery of the extension, inflates the seal and extends it lengthwise until as the pressure increases the collar gradually exposes a cross passage 21 leading to an outlet bore 20 in the stem 19. The stem may be anchored by spikes 34 and in either case the shot blast urges it and the extension 11 back through the seal, which is in gripping contact with the hole 26 and may therefore be torn from the extension at the clamped end 31. In another form the seal is reinforced longitudinally, so that it contracts lengthwise as it inflates and aligns a cross passage in an inward extension of the sliding collar with the outlet cross passage. In a modification, Fig. 8, each end of the seal is mounted on a sliding collar 48, 49, an annular space is left around the tube extension 39 between the collars and a coil spring 51 is compressed betwen the collar 49 and the anchor of a collar 50 to urge the collar 48 against an annular shoulder 52 of the extension, exposing the water inlet cross passage 42 until the blast causes the extension to slide back in the collars without damage to the seal and thereby close the passage 42 to prevent back pressure on the water supply. Specification 853,273 is referred to.

Filed: 1925-10-22
Abstract: 242,618. Metallbank und Metallurgische Ges. Akt.-Ges. Nov. 4, 1924, [Convention date]. Gravity, materials falling by. - In the drying or low temperature distillation of fuel by the passage therethrough of hot gases the furnace in which hot gases are generated is arranged between two retorts, but separated from them by chambers through which gases are passed to be heated and to mix with the hot combustion gases from the furnace before entering the retorts. Each retort comprises a distilling chamber 1 and a coke cooling zone 14, combustible gases being introduced at inlets 15 and channels 16 and being heated by the coke before reaching collecting chambers 17 and passing through openings 18, conduits 9, and openings 20 to channels 3. Combustion products from a furnace 6 mix with the gases and pass through the distillation chambers 1 to the gas outlet 22, from which a portion of the gas may be returned to the inlet 15 and to the burner 23 of the furnace. The cooled coke is discharged through a door 24. When employed for drying a temperature lower than that necessary for carbonization is maintained and the heating is produced exclusively by burning a gas obtained from any 'source or powdered or liquid fuel. The drying and the carbonizing apparatus may be superimposed and heated by the same furnace.

Abstract: 1431081 Spray-producers; mixing apparatus HUDSON OXYGEN THERAPY SALES CO 5 June 1973 [22 June 1972] 26858/73 Headings B1C and B2F [Also in Divisions A5 and F2] An atomiser, or nebuliser, comprises a cap 14 which is part of a manifold, and a jar 16 which is preferably threaded to be received into the cap, and has a bottom 62 with an integral air nozzle 44 having an interior 43 through which gas is upwardly directed. At the nozzle apex is an orifice 49 and the nozzle 44 is frusto-conically shaped. An aspirator cap 42 is disposed coaxially on the nozzle 44, its bottom surface 55 being slightly elevated off the bowl 62 to provide a passage for water or medicament. Alternatively, the surface 55 may seat on bowl 62 with passageways formed through its lower end. At the upper end of cap 42 is an orifice 47 in line with orifice 49. The interior of the aspirator cap is cut to provide four flattened surfaces which rest on the exterior of nozzle 44, Fig. 12 (not shown), to form channels 53 between the nozzle 44 and the cap 42, so that fluids can be drawn up the channels to mixing chamber 51 between orifices 47 and 49. In an alternative form the interior of the aspirator cap may be cylindrical and the exterior of the nozzle surface bevelled to produce channels. Gas supplied via line 52 to nozzle 44 creates a depression on emerging from nozzle 49, drawing liquid upwardly within channels 53 into chamber 51 so that a mist impinges on baffle 46 which breaks up the droplets further. The baffle 46 comprises a body having a plurality of arms 40 flanged inwardly at 59 for attachment to the exterior of cap 42. To achieve the preferred range of particle sizes the nozzle orifice diameter should lie between 0.030 and 0.032 inches and the aspirator orifice should lie between 0.041 and 0.043 inches. The distance 'between the upper edge of the nozzle orifice and the lower edge of the aspirator cap orifice should be greater than the diameter of either orifice, and preferably twice the diameter of the aspirator cap orifice.

Abstract: 209,013. Haynes, E. J. Oct. 29, 1923. Sounding-apparatus.-A line for use with pneu. matic sounding-apparatus consists of an air-tube 1 surrounded by an inner armour consisting of a number of metal collars 2 and flexible coils 3 arranged alternately along the tube. Upon this armour is helically wound a cable 4 formed of wire rope the strands of which are acutely pitched to resist longitudinal stresses. The whole is surrounded by an outer armour consisting of a number of metal sleeves 5 abutting together pivotally so as not to interfere with the flexibility of the tube. Each sleeve is formed at one end with two diametrically-opposed obtusely-pointed tongues 6 separated by concave portions 7, while at its other end it is formed with recesses 8 in which the tongues 6 of the. next sleeve engage. Between the recesses are convex parts 9 having less curvature than the parts 7. The. tongues 6 of a given sleeve are removed a quarter turn circumferentially from the recesses 8 of the same sleeve, thus rendering the tube flexible in any direction. The coils 3 of the inner armour are in radial alignment with the abutting ends of the sleeves 5.

A method of rolling sheet or strip material comprises passing the material between two roll assemblies which are prestressed to oppose a force tending to separate the roll assemblies, the prestressing force being automatically controlled such that it is always greater than the separating force by a predetermined value. In operation, screw jacks 28 are operated through gearing by motors 42, which are interconnected by a clutch 48, to adjust the roll pass, hydraulic jacks 74-76 urging work rolls 14 in chocks 15 against back-up rolls 17. Hydraulic fluid is then pumped into cylinders 58 in each roll frame 11 until the jacks are prestressed in compression to the desired degree, loadmeters 53 beneath the jacks measuring the pressure. Any variation measured by the loadmeters during rolling is fed electrically to an hydraulic pump 64 which then corrects the pressure in the cylinders 58 so that the required difference in forces is maintained. Axial movement of the rolls is prevented by plates 22 and 24.

[Also in Group XXIX] The static gas pressure, e.g. in an air bag or a number of individual supports for the mirror of a reflecting telescope, is controlled by passing the gas supply through the space 9 between the end of a piston 2 and a container 1 which is oriented so that the weight of the piston or a component thereof acts on the gas in the space. Gas enters the container 1 through a connection 8 and flows past a restriction 13 of fixed length and through jets 10 and a restriction 14 whose length varies with the position of the piston to an outlet 12, the mirror support being supplied by a connection 11. The piston is made of two parts 2a, 2b of different density materials, such as aluminium and mild steel, and the device is mounted with its longitudinal axis parallel to the optical axis of the mirror whereby the desired supporting pressure is automatically provided for each attitude of the mirror. Air from jets 3 rotates the piston and leaves the container at its open end and by way of an outlet 6. The Specification gives examples of dimensions and pressures.
