Filed: 1966-07-12
Abstract: 1,136,863. Seismic impulse devices. PETTY GEOPHYSICAL ENG. CO. 12 July, 1966, No. 31254/66. Heading H4D. Seismic impulses are generated by means of an hydraulically operated hammer striking a base plate in contact with the ground, the assembly of hammer and base plate which is carried by a truck being raised and lowered by hydraulic means, the base plate in the lowered position resting on the ground and supporting the hammer and at least a portion of the weight of the truck. In Fig. 1 (not shown) the general arrangement is depicted with the base plate (21) in contact with the ground and bearing a portion of the weight of the truck, an hydraulic cylinder-piston device (14) and hydraulic control mechanism (16). Fig. 2 shows one embodiment in which the base plate 21 is supported via ball joints 59 and rods 52 (which may be hydraulic cylinders) by an assembly 25 which may be raised and lowered with respect to a cylinder 24 (secured to the truck) by pressure fluid (oil) admitted to the appropriate side of flange 42 (i.e. chamber 35 or 37) via valve 29B with a corresponding release to reservoir 28 via valve 29A, a preloaded outlet pressure valve 40 operating to damp the downward motion when flange 42 covers the round outlet pipe 41. The upward movement of the assembly may be similarly damped. For effecting the hammer action a fast acting valve 61A releases pressure fluid (supplied via a flexible tube 31 to chamber 60) into driving chamber 60A to force hammer 20 against plate 21 and retraction of the hammer is effected via a fast acting valve 61B (which is open when valve 61A is closed and vice versa) communicating via passage 62 and flexible tube 30 with reservoir 28 the pressure in which is sub-atmosphere. To prevent damage to the equipment should the base plate be forced against a comparatively unyielding area such as a rock 45 shear pins or fracturable I-beams 65 are provided. In a second embodiment the assembly 25<SP>1</SP> (Fig. 5) is raised and lowered by the introduction of pressure fluid to chambers 37<SP>1</SP> and 35 (as in the Fig. 2 arrangement) and the operation of hammer is effected by means of a slide valve assembly 61A driven by an hydraulic piston 101, to release hydraulic pressure from chamber 60<SP>1</SP> into the driving chamber 60A. The hydraulic control system for the arrangement of Fig. 5 is described with reference to Figs. 3 and 4 (not shown) and the construction of the hammer is described with reference to Fig. 6 (not shown).

Title: Method and apparatus for treating gases with liquids
IPC: B01J19/00
Filed: 1938-11-01
Abstract: 520,839. Absorbing gases in liquids. FANSTEEL METALLURGICAL CORPORATION. Nov. 1, 1938, Nos. 31562 and 31563. Convention dates, Nov. 15, 1937, and Oct. 17, 1938. [Class 55 (ii)] [Also in Group XXII] In conducting an exothermic reaction between a gas and a liquid, as in the manufacture of hydrochloric acid, the gas and liquid are passed in concurrent flow in contact with a cooling wall cooled by a medium such as water on its opposite side, the mixture of reacting and non-reacting gas being removed before completion of the reaction from the reacted liquid which is further cooled. An absorbing column 14, preferably of thin tantalum and with spaced circumferential ribs 66, is surmounted by a chamber 16 to which hydrochloric acid gas is delivered through a pipe 10 and weak hydrochloric acid through a pipe 18, the liquid passing under a gas trap 22 and over a notched distributor 24 to form a number of streams down the inside wall. A jacket 26 is supplied with cooling water at spaced points through a pipe 28 and has a discharge pipe 30. A separate jacket 45 surrounds the lower part of the column from which acid is withdrawn through a pipe 48. The cooling water supplies are regulated in dependence on their outlet temperature. Unabsorbed gas is removed from the column just above the level of the lower jacket through a tube 38 whence it is passed to a scrubber 54 in which it forms with water, introduced through an inlet 56, weak acid for supply to the column. The water supply valve may be regulated in dependence on the specific gravity of acid issuing through pipe 48. In a modification, gas is introduced into the column through perforations in an inner tube of which the upper part is tantalum, and the lower part is non-metallic; unabsorbed gas is withdrawn through perforations at the lower end of the distributor tube into the outlet tube 38. Gas rich in hydrogen chloride may be introduced into the column immediately below this point to increase the acid concentration. Niobium and tantalum-niobium alloys may be used instead of tantalum. In an example, gases at 90‹-120‹ F. containing 90 per cent. hydrochloric acid are supplied to a 6ft. column, the cooling water temperature rising from about 75‹ to 140‹-170‹ F. Or brine at 20‹-40‹ F. may be used when very strong acid is to be stored under superatmospheric pressure required.

Patent GB-667069-A (GB)
Title: An improved method for removing volatile matter from rolls of long lengths of unwoven sheet materials in preparation for coating under vacuum
IPC: C23C14/20
Filed: 1948-12-08
Abstract: <PICT:0667069/IV (a)/1> <PICT:0667069/IV (a)/2> Rolls of long lengths of unwoven sheet materials are prepared for the application of coating under vacuum by repeatedly unrolling and re-rolling the sheet materials in an atmosphere substantially at a pressure of 10 microns of mercury absolute pressure, the rate of exposure to this vacuum being at least 25 linear feet per minute.  In the example, two rolls of sheet material, such as 500-foot rolls of cellulose acetate sheeting are placed on one of the two rollers 89 (Fig. 1), which are connected with the pulleys 92, Fig. 2, unrolled around idler rollers 91, Fig. 1, and fastened to the other roller 89.  The gas-tight degassing chamber 81 is evacuated to a pressure of about 10 microns Hg by means of a diffusion pump and a mechanical backing pump connected with conduits 56 and 66.  Pulleys 92 are then driven by means of belts 93 and the motor and speed reduction gear 94 so that the sheeting is unrolled from one of the rollers 89 and rolled up on the other at such a speed that the sheeting is exposed to the vacuum between the rollers at the rate of 100 linear feet per minute.  When all the sheeting has thus been transferred from one of the rollers 89 to the other, the direction of rotation of the rollers is reversed and this cycle is repeated until the sheeting ceases to give off volatile matter at a rate which would interfere with the subsequent deposition of coating material thereon.  About 35 exposures of the sheeting in the above manner may be necessary to reach this stage. After the volatile matter has been removed from the sheeting the latter is removed from the degassing chamber in tightly rolled form. If the sheeting material is an air-tight plastic it may be stored exposed to the atmosphere for a number of hours before being coated without appreciable re-absorption of moisture &c.
