Title: A damped vibration isolating system
IPC: F16F1/371
Filed: 1966-02-03
Abstract: 1,091,752. Vibration isolators. SANDERS ASSOCIATES Inc. Feb. 3, 1966 [Feb. 4, 1965], No. 4839/66. Heading F2S. A vibration and shock isolating system comprises a part to be isolated from vibration and an isolating medium mechanically coupling the part to a source of vibration the medium being of foam material such as polyurethane, silicone rubber, natural rubber, polyvinylchloride &c., impregnated with a damping substance, e.g. polysulphide, polychloroprene, polyacrylate &c., which is usually dissolved in a suitable solvent applied to the foam, the solvent being subsequently driven off. The dimensions, mass, and other physical characteristics of the isolator and the parts to be isolated thereby are preferably proportioned for critical damping of the system and the impregnants should be of the non- hardening visco-elastic type. As a general rule the mass should be of the open cell type; however, closed cells could be used in which case the impregnants should be mixed in before the material is foamed. As shown in Fig. 2 a housing 26, containing parts to be isolated from external vibrations, is supported by a number of isolators such as 28, 30 each of which comprises a plate 44 which is sandwiched between impregnated foam slabs 46, 48 accommodated in a housing 32, 34 and which is connected to a load-bearing stud 38 which projects upwardly through an aperture 36 in the housing 32, 34 and is screwed, at 42, to the housing 26. A seal 50 closes off the aperture 36. The slabs 46, 48 are preferably bonded to the plate 44, the stud 38, the housing 32, 34, and the seal 50. An isolator of this kind can be employed to damp torsional vibrations. In a modification, Fig. 3, not shown, a spring (56), which may be selected to balance a part, or all, of the static load, is added. In a further modification, Fig. 1, not shown, three mounting boards (10, 12, 14) for electronic components are encased, by impregnated foam slabs (18, 20, 22, 24), in a housing (16), the slabs being preferably bonded to the mounting boards, electronic components, and the housing. Any electrical leads extending between the casing and the boards should be of relatively limp construction.

Title: Improvements relating to processes for the production of multi-coloured patterned sponge rubber
IPC: C08J9/00
Filed: 1955-02-18
Abstract: In a process for making multi-coloured patterned sponge rubber, pieces of individually coloured raw rubber compositions containing blowing agents and treated with a material, e.g. talcum, for preventing them from sticking together, are arranged as a loose mass of uniform height in an open container and heated so that the pieces combine to form a continuous mass which is expanded by the gas released by the blowing agents and is then vulcanized.  The pieces may be arranged indiscriminately in the container to form an indeterminate pattern or may be arranged to form a desired pattern. The process may be employed for manufacturing sponge rubber mats.

Title: Improvements relating to insulated electric conductors
IPC: H01B7/22
Filed: 1928-02-17
Abstract: 302,522. Siemens Bros. & Co., Ltd., and Foster, A. E. Feb. 17. 1928. Armouring.-Relates to the helical wrapping of thin metal tape, usually of brass or copper, which is wound on a submarine or other electric cable to protect it against the attack of boring insects. According to ihe invention, the metal tape c is wound on the insulated core a with overlapping edges, and the fabric tape b, which is interposed between the tape c and the core, is made of such a width that it protrudes between the windings and partly or wholly covers their exterior. With this construction, the fabric absorbs moisture quickly and forms a good " earth " when the core is submerged in water for the purpose of testing for defects in the insulation. The fabric protects the metal wrapping externally as well as internally, and its thickness is not sufficient to allow insects to penetrate between the overlapping edges of the metal tape.

Title: A process for the separation and recovery of hydrocarbons of different degrees of saturation
IPC: C07C7/11
Filed: 1941-04-21
Abstract: 548,734. Separating light hydrocarbons. FIFE, J. G. (Shell Development Co.). April 21, 1941, No. 5140. [Class 32] [Also in Group IV] Hydrocarbons of different degrees of saturation contained in hydrocarbon vapour mixtures of relatively narrow boiling range are separated by bringing the vapour into contact with a liquid solvent mixture containing 5-35 per cent. by weight of water and 95-65 per cent. by weight of morpholine, dioxane, acetone, methyl ethyl ketone, acetonitrile, or lactonitrile to dissolve selectively the hydrocarbons of lesser degree of saturation which are then recovered from the solution. The vapour may be scrubbed by the solvent in a spray, packed, or bubble plate tower or the solvent may be caused to flow down a distillation column as the distillation proceeds. The process may be applied to the separation of acetylene from ethane or ethylene, ethylene from ethane, propylene from propane, butadiene from butylenes, butane &c., butylenes from butane, pentadienes such as isoprene from fractions containing five carbon atoms, cyclopentadiene from cyclopentane or pentenes &c.

Title: Improvements in or relating to temporary tubular frameworks such as for market booths and similar erections
IPC: E04G7/18
Filed: 1937-02-23
Abstract: 489,786. Scaffold and like clamps. MILLS SCAFFOLD CO., Ltd., and CASWELL, G. F. C. Feb. 23, 1937, No. 5442. [Class 20 (ii)] Tubular members of temporary frameworks, such as for market booths, are interconnected by means of a bolt or the like passing diametrically through one member and partly embracing another member, and are prevented from moving laterally or longitudinally by means of a projection or projections on one member which co-operate with the other member. The bolt 3, Fig. 2, passes through the tube 2 and its flattened hook-shaped end 7 partly embraces the tube 1. A pin 8 passes diametrically through the tube 2 to which it is welded and projects through a hole 10 in the tube 1 to prevent movement of the tubes when they are clamped in position. The clamping and releasing of the parts are effected by a wing nut 5. In a modification, a nose on the hook 7 projects downwards into a hole in the tube 1. In the construction shown in Fig. 4, a sleeve 16 is connected by a pin 17 to a tube la and projects into the bore of a tube 1b. These tubes, which are thus arranged end to end, are connected together and to a further tube 2 by a bolt 4. The bolt passes diametrically through the tube 2 and a nose 14 on its hooked end enters holes 20 formed in the tube 1b and sleeve 16. The tube and sleeve also have holes 19 for receiving the projecting end of the pin 8. In a further modification, an external semi-cylindrical sleeve is welded to one tube and functions in a similar manner to the sleeve 16.

Title: Fluid pressure seals
IPC: F16J15/32
Filed: 1961-02-14
Abstract: 979,792. Piston and stuffing-box packing. B. F. GOODRICH CO. Feb. 14, 1961 [Feb. 23, 1960], No. 5466/61. Headings F2B and F2T. A packing arrangement 10 includes a sealing ring 15 comprising a body 19 and a frustoconical sealing flange 20 terminating in a narrow sealing edge 21 which is urged into sealing contact with a cylindrical surface, e.g. the surface 12 of a rod 11 projecting through a housing 13, by deflection of the flange about its juncture 23 with the body 19, the amount of deflection being limited by an adjusting sleeve 17. The ring 15 is sealed to a bore 27 of the casing by a ring member 40 attached to the body 19 by a thin radial web 43, Fig. 3, and having a narrow sealing edge 42. The flange 20 is clamped at a thickened region 25 adjacent its sealing edge between a nose 29 of a spacer ring 16 and an adjusting sleeve 17 threaded into the body 19. The spacer ring 16 and the sealing ring 15 are formed so that, when unstressed, they slide freely in the bore 27 and on the rod 10. In assembling the seal, the spacer ring 16 is first positioned and the sealing ring 15, preferably with the sleeve 17 part-way threaded in the body 19, is placed with its region 25 against the nose 29. The ring 15 is then forced toward the ring 16 by a loading nut 18 screwed on the housing 13, such action causing the flange 20 to bend about the juncture 23 whereby the sealing edge 21 is forced into contact with the rod 10. At the same time the member 40 is flexed about the radial web 43 by pins 45 to press the sealing edge 42 against the bore 27. When the required sealing pressure at the edge 21 is obtained the sleeve 17 is screwed in until it abuts the flange 20 opposite the nose 29. The ring 15 is preferably of metal and preferably all the components of the seal are of metal having the same thermal expansion charactetistics. The rod 10 may have its surface case hardened or plated with chromium. Fig. 5 shows a piston packing according to the invention, the sealing ring 315 having a flange 320 with a sealing edge 321 which is pressed into contact with the cylinder wall 312 by deflection of the flange by a bolt 318 threaded into the piston and engaging the body 319 of the ring 315. The flange 320 is locked in position by an adjusting sleeve 317 screwed on the ring 315. In a modification for sealing a rod, the spacer ring 16 is spring-urged against the flange 20.

Title: Solvent extraction of hydrocarbon oils
IPC: F02B3/06
Filed: 1956-02-22
Abstract: Hydrocarbon oils, including petroleum and shale oils, are segregated into their relatively more aromatic fractions and relatively more paraffinic fractions by extracting with a lactone and separation of a solvent extract phase and a raffinate phase. Lactones referred to are g -butyrolactone, b -propiolactone, angelicalactone and g -valerolactone.  Solvent modifiers such as water, water-soluble aliphatic alcohols, ethylene glycol and acetic acid may be added to the lactone in amounts less than 1/3 of the total solvent composition.  A mixture of 90 per cent butyrolactone and 10 per cent water is specified.  The extraction may be carried out in more than 1 stage and may be a batch or continuous and countercurrent process. The process may be used to remove, besides aromatic compounds, olefinic metal contaminants such as Ni, Va and Fe, and nitrogen compounds; gas oil fractions, kerosene, diesel fuel, residual petroleum fractions, thermally or catalytically cracked naphthas, lubricating oil boiling in the gas oil range, and shale and hydrogenated shale oils.  The process may be carried out at a temperature of 80-500 DEG  F. and a pressure of 15-750 p.s.i.  From 0.5 to 3 volumes of solvent per volume of oil treated may be used. Gas oil may be treated and the raffinate phase catalytically cracked. Alternatively, virgin naphtha may be hydroformed and after removal of C5 and lighter fractions, the hydroformate may be extracted with g -butyrolactone.

Title: Improvements in or relating to the measurement of physical values
IPC: G01R17/08
Filed: 1953-02-27
Abstract: 751,852. Electric indicating systems. TINSLEY (INDUSTRIAL INSTRUMENTS), Ltd., and STEGHART, F. L. F. Feb. 15, 1954 [Feb. 27 1953], No. 5613/53. Class. 40(1) A variable, e.g. fluid-flow, pressure, temperature or electric current, is measured translating it into a corresponding force which is automatically balanced by a counter force controlled by an electric current derived from an electromagnetic pick-off responsive to force unbalance and amplified in a magnetic amplifier. Further thermionic amplification may be provided, and the amplifier current output which may provide the counter force electromagnetically, may serve to indicate or control the variable in question. As shown, the rate of fluid flow in a pipe 1 is converted by a venturi 2, diaphragm 4 and a mechanical amplifying lever system 10-15 into a corresponding displacement of a lever 7 about its pivot 8. The lever 7 carries a coil 18 movable along the core leg 19 of an A.C. electromagnet 20 in such a way that the e.m.f. induced in the coil varies in magnitude and phase sense according to the magnitude and sense of the displacement of the lever 7 from a neutral position. This control voltage is fed through a rectifier 23 to the control windings 25, 25a of a magnetic amplifier 24. The amplifier energizing and output windings 27, 27a are series fed from a transformer 22-26 and through a rectifier 30 supply positive feed back windings 29, 29a to increase the amplification. Through a further rectifier 28 the output A.C. windings supply a corresponding pulsating D.C. through coils 34-36. The coil 34 is carried by the lever 7 and moves in the gap of a magnet 35 energized by the coil 36 until the two torques exerted on the lever 7 balance one another when the current in the coils 34-36 is a measure of the fluid-flow and is indicated at 31 recorded at 32 and integrated at 33. Since both coils 34-36 are energized by the output current the meter reading at 31 is directly proportional to fluid flow. The rectifier 28 may be dispensed with if moving iron instruments are used. In a modification (Fig. 2, not shown), a thermionic amplifier is disposed between the magnetic amplifier and the output circuit 31-35. Temperature may be measured by using a bimetallic strip to actuate the lever 7, or the current produced by a thermocouple or resistance thermometer may be supplied to a D.C. electromagnet which actuates the lever 7. Electric current may be measured by applying it to this magnet.
