Title: Improvements in or relating to apparatus for retarding advance of a line under load
IPC: B64D1/02
Filed: 1950-07-07
Abstract: 672,160. Rope grips. FRIEDER, L. P. July 7, 1950. [July 12, 1949] No. 17021/50 Class 78 (ii). Apparatus for retarding advance of a line under load comprises gripping members between which the load line passes and linked together to move into frictional engagement with the line upon exertion of load force on one member relative to the other, one of the members includes a device engaged by the line for drawing the members together under the load force, the other member being separatelv connected to oppose the load force on the limbed members, for coaction to effect the drawing of the members together by engagement of the line with the device. A rope 36 is coiled on a reel 34 secured to a link 44 for suspension from a balloon or the like. The rope passes through holes 70 in an extension 54 of a gripping member 51 and then between the two channelled gripping members 50, 51 and then through holes 71 in an extension 64 of member 50, the load being attached to the end of the rope. The members 50, 51 have each a hole at opposite ends through which the rope also passes, the members being connected together by links 66, 67. The rate of unwinding can be varied by altering the selection of holes 70, 71 through which the rope passes. The upper and lower parts are contained in a protective casing when in use. The rate of descent may be increased by having an enlarged hole between the upper holes, with a projecting tab over which the rope passes. The holes may also be arranged other than in a straight line. The rope may be of gradually decreasing diameter. In a modified form the rope passes between the two gripping members and the rope is retarded by passing a few turns of the rope round a horizontal spindle connected to the lower end of one of the gripping members. For the release of a parachute contained in the balloon, the neck of the balloon is secured to a cover 163, Figs. 16 and 19, screwed into a housing 160. To inflate the balloon a conduit is passed over the housing and air is forced into the balloon between the cover 166 and closure 167 to the housing through holes 172 in the cover into the balloon. The conduit is then removed and screwed to the housing 160 is a yoke 141 carrying a reel 142 for the rope 144 which is connected to a speed retarding device and to the load. When the balloon is burst the parachute can then deploy paying out its load line 193, Fig. 19, from its holder bringing the load slowly and safely to earth. The parachute may be released when the load line is extended by severing the release cord by an electric current bv supplementary means. The rope is then wound on a reel similar to 34 over a movable member contained partly inside the reel and which when the rope is unwound is free to move to make contact with a battery and two other contacts which complete a circuit to sever and release cord to allow the parachute to deploy.

Title: Method of gasifying crude oil
IPC: C07C67/00
Filed: 1973-09-26
Abstract: 1453082 Synthetic natural gas AIR PRODUCTS & CHEMICALS Inc 26 Sept 1973 [12 Oct 1972] 17058/76 Divided out of 1453081 Heading C5E Gaseous hydrogen is introduced into a pool of a crude oil in a vaporization vessel at 800- 1000 F. to produce a mixture of hydrogen and vaporized oil above the pool of oil, the mixture of hydrogen and vaporized oil is reacted in a hydrogasification vessel to form an effluent consisting essentially of hydrogen, methane, ethane, aromatic hydrocarbons and hydrogen sulphide, and the effluent is cooled to condense and separate aromatic hydrocarbons therefrom. A crude oil 12 is topped to remove a naphtha of end point 360 F. and then partially vaporized by sparging preheated hydrogen from beneath the surface of a pool of the heated oil. The vaporized oil-hydrogen mixture is reacted in a gas recycle hydrogenator (illustrated in Fig. 2 not shown) at 1000-1400 F. The hydrogen used in the vaporization and gasification of the oil is produced at 20 by partial oxidation of the unevaporated portion 42 of oil from the vaporizer and of a portion of the residual aromatics 36, followed by a water gas shift reaction, removal of H 2  and CO 2  and methanation to remove CO. The gasification effluent 22 is cooled and a stream 44 of hydrogen sulphide and a stream 36 of aromatics are removed. The purified effluent 46 is cooled in the cryogenic separation zone 48 to separate liquefied methane and ethane from the hydrogen 52 which is recycled. The naphtha stream 18 is reacted with steam in a first catalytic rich gas reaction (Fig 1a, not shown) to produce an effluent which is mixed with the methane-ethane stream 50, further reacted with stean in a second catalytic rich gas reactor and then subjected to methanation followed by CO 2  removal.

Title: Improvements in methods of purifying refractory carboncontaining compounds of titanium and zirconium
IPC: C01B31/30
Filed: 1942-12-03
Abstract: 564,603. Flotation processes. EVERY, C. E. (Titanium Alloy Manufacturing Co.). Dec. 3, 1942, No. 17230. [Class 82 (ii)] [Also in Group III] Titanium and zirconium carbides, cyanonitrides and carboxides are purified from free carbon by agitating in a state of fine division with a 0.1-1.5, preferably 0.25-0.5 per cent aqueous soap solution, settling, and pouring off the supernatant liquid. The material is generally ground to at least 200 mesh, a satisfactory fineness being such that 5 per cent or less remains on a 325 mesh screen. Iron from the grinding balls is removed by hydrochloric acid. About 10 g. of soap per kg. of material gives satisfactory results, the treat ment usually being repeated several times. Agitation is continued until the carbon is completely emulsified, the formation of froth being avoided. The time for settling is sufficient to allow the carbide or other compound to form a coherent cake which does not disintegrate when the vessel is tilted to pour off the liquid containing suspended carbon. The residual cake may be washed if desired. In examples : (1) titanium carbide of finer than 325 mesh is agitated with a 0.25 per cent solution in tap water of a sodium fatty acid soap followed by settling for 5 hours and decanting; (2) titanium carbide. from the decantations resulting from a purification with tannic acid is stirred with 0.3 per cent soap solution for 15 mins. and allowed to settle for 3 hours. A coherent cake forms beneath an intermediate layer containing graphite and some carbide, and a top layer containing graphite which are decanted. The cake is treated twice with a soap solution of about 0.4 per cent when only a single layer of liquor separates from the carbide cake ; (4) zirconium carbide or cyanonitride or titanium cyanonitride is agitated with sodium fatty acid soap solution and the cake settling out from the upper layer which is poured off, is washed. Other sodium and potassium soaps including liquid soaps may be used.

Title: Improvements in or relating to Radiators for Cooling Fluids.
Inventor: JAMES JOHN MELVILLE
IPC: F28F9/26
Filed: 1918-10-24
Abstract: 134,277. James, J. M., Talbot, E., and Davison, E. G. Oct. 24, 1918. Plate apparatus.-Radiators for cooling fluids are constructed of flat hollow elements A held together by one or more bolts D passing through the apertures A<2> connecting the interiors of adjacent plates. In place of the separate distancerings normally used in this type of apparatus tu prevent crushing on tightening up the bolt, one plate of each unit is flanged inwards to bear against the opposite plate, and perforated as at A<6>, Fig. 5. The other plate is flanged outward to form a spigot A<5> which engages in the fancet formed in an adjacent plate. Or both plates may be flanged inwards. The invention is stated to be applicable to the formation of D or V fronted radiators by staggering the spigot in relation to the fancet in each unit, the axis of the aperture A<2> being thus inclined, or by arranging two groups constructed, as shown in Fig. 1, at an angle to the other and united by T-pieces. The plates may be corrugated.

Title: A centrifugal extraction method operating in countercurrent as well as an extractor suitable for this purpose
IPC: C11B1/10
Filed: 1962-05-07
Abstract: Vanillin is extracted from sulphite waste liquor, using toluene as an extraction agent, by circulating the waste liquor in countercurrent to the toluene in a centrifugal extractor (see Divisions B1 and B2) and recirculating part of the vanillin-containing toluene leaving the extractor to the inlet for the waste liquor. A centrifugal pump, which may be followed by a diffuser, is inserted in the waste liquor inlet pipe for mixing the latter with the portion of the toluene to be recirculated. Alternatively, part of the substantially vanillin-free waste liquor is recirculated to the inlet for the toluene.  A number of extractors may be connected in series, the toluene becoming gradually enriched with vanillin as it circulates from one extractor to the next in countercurrent to the waste liquor which becomes correspondingly gradually poorer in vanillin. The same process may be employed for extracting phenol from gas works water using benzene as the extraction agent. Specifications 815,029 and 941,937 are referred to.ALSO:In a centrifugal extraction process the liquid components fed to the extractor (see Divisions B1 and B2) are caused to circulate in counter-current within the extractor and part of at least one component discharging therefrom is recirculated into the extractor by being fed to the inlet for the other component.  As applied to the extraction of glycerol from a soap solution coming from the saponification stage of a continuous soap-making process and using a solution of common salt as the extraction agent, the glycerol-containing salt solution leaving the extractor is partly recirculated to the soap solution inlet. Part of the purified soap solution may also be recirculated to the inlet of the fresh salt solution. A member of extractors may be connected in series, the salt solution becoming gradually enriched with glycerol as it circulates from one extractor to the next in countercurrent to the soap solution which becomes correspondingly poorer in glycerol. The process may also be applied to the extraction of aromatic and unsaturated aliphatic hydrocarbons from shale or mineral oil using furfural as an extraction agent.  Proportions of the components used, their composition and results of extraction processes are given. Specifications 815,029 and 941,937 are referred to.

Title: Improvements relating to motor vehicles
IPC: B60S1/18
Filed: 1933-06-20
Abstract: 421,584. Driving windscreen-wipers on motor vehicles. TRICO PRODUCTS CORPORATION, 817, Washington Street, Buffalo, New York, U.S.A. June 20, 1933, No. 17609. Convention date, June 23, 1932. [Class 79 (ii)] The windscreen-wiper is driven from a member subject to the variations in speed of the engine or power unit through transmission means including a speed-responsive control governed by the speed of the wiper for maintaining a substantially-constant wiper speed when the speed of said member exceeds a predetermined maximum. In the construction shown the wiper arms 3 are driven through a flexible shaft 25 and a centrifugal clutch 28 from the cam-shaft 27 of the engine 1. The clutch arms or segments 28 are pivoted at 29 to a member 30 splined on a shaft 25<1> and are drawn inwards to grip the coned end 31 of the driving shaft 27 by means of a spring ring 32. When the speed of the wiper, and therefore of the driven shaft 25<1>, becomes excessive the arms 28 swing outwardly against the spring tension and slip on the cone 31 so as to maintain the speed of the wiper constant. The clutch may be disconnected by means of a lever 35 and Bowden wire mechanism 37 actuated by a knob (not shown) which also brings the wiper blades to rest in their out-of-use positions. The flexible shaft 28 drives the wiper blades through worm gearing 24, a crank-pin 22 which reciprocates a rack 5, and spur gearing between the rack and arms actuating the wiper blades. Specification 270,028, [Class 79 (ii)], is referred to. The Specification as open to inspection under Sect. 91 describes also the subject-matter of Specification 421,688, [Group XXIII]. This subject-matter does not appear in the Specification as accepted.

Title: Improvements relating to wire-drawing machines
IPC: B21C9/00
Filed: 1921-06-29
Abstract: 165,732. Picotin, J. June 30, 1920, [Convention date]. Drawing wire.-In drawing wire, the wire is cooled immediately after passing through the die, so that the heat generated by drawing may be utilized to keep the wire ductile during drawing and the wire then quickly cooled, prior to reaching the winding drum. Further, the wire may be heated if desired prior to drawing, or may be lubricated prior to drawing with a liquid different from the cooling liquid. As shown in Fig. 3, the wire is drawn by drums g, g', &c. through a series of dies f, f<1>, &c., having on their exit sides cooling baths a through which the wire passes, the baths having inlet and overflow tubes b, c. The drums g, g<1>, &c., may be on separate shafts or they may be of required diameters so as to be mounted on a common shaft. The wire on leaving the baths carries a portion of the liquid to the drums so that it may slide more easily thereon. In an apparatus as shown in Fig. 2, winding drums carried at each end of a shaft 2 driven by a central pulley 3, are arranged to draw separate wires from spools 21 in a receptacle 22 containing hot lubricant through dies 4 that form the bottoms of cooling baths 16, which are clamped to a tube 12 reciprocated by a cam to facilitate winding. The dies are held in position by spring-pressed members 17, and cooling liquid is supplied to the baths from the tube through an aperture controlled by a screw 14. When previous beating is not required the wire may be lubricated by the cooling liquid prior to drawing, the liquid being supplied to a rod 20. The pulley 3 is driven by a belt which is tensioned by a roller 5 carried by a holder rotatably mounted on a bearing and operated by a handle 7. The holder is normally pressed by a spring against the side of the pulley so as to hold it stationary, but is moved away therefrom, when the handle is operated, by a screw carried thereby engaging a helical slot in the upper end of the member 1.

Title: Improvements in and relating to change speed gears
IPC: F16H15/56
Filed: 1923-07-09
Abstract: 217,444. Garrard, C. G. July 9, 1923. Variable-speed epicyclic gearing comprises group-friction rollers 19, 22 supported upon a carrier 18 secured to a driven shaft 15 and rolling round between a driving internal gear 6 and sun gears 27, 35 adapted to be held fast alternatively by sliding dog-ended sleeves 30, 43. There is a separate reversing-train, 33, 23, 35. The rollers are curved and the frictional pressure is supplied by lateral thrust as described in Specifications 211,521, [Class 80 (i), Gearing, Belt &c.], and 217,403. The lateral thrust is supplied by the springs 7 which hold in action a main friction clutch 4 which connects a driving fly-wheel 1 to the gear members 6, 33. The sleeve 30 is loose, and when thrust to the left engages clutch dogs 31 on the carrier 18 while remaining in engagement with dogs 28 inside the gear 27. This produces a solid high-speed drive. On moving this sleeve to the right, a clutch head 38 at its other end engages fixed teeth 39, with the result that the gear 27 is held against rotation. The rollers 19 act to effect a middle speed. The low speed is effected after freeing the sleeve 30 by holding fast the gear 35 by sliding sleeve 43 to the left into engagement with internal dogs 41. This sleeve 43, which is prevented from rotating by feathers 44, is slid to the right to effect the reversed drive until dogs 42 engage dogs 55 inside the carrier 26 of the planets 23. In this drive the internal gears 6, 33 turn at engine speed. The planets 19, 23, which are thus driven, are connected by the loose element 35. The carrier 26 being fixed, the carrier 18 is driven reversely. The sleeves 30, 43 are operated selectively by a ball-supported lever 48.

Abstract: 530,142. Aircraft landing gear. AIRCRAFT COMPONENTS, Ltd., and BRIDGES, D. G. June 17, 1939, No. 17772. [Class 4] A retractable aircraft undercarriage operated by a double-acting jack has a single-notched latch adapted to engage alternative detents for locking the undercarriage in the up and down positions, by latch movement in the same sense in each case. A pivoted leg 1 is braced by a breakable strut 2, 3, which is locked in the extended position by a latch 10 pivoted to the strut section 3 at 11 and having a notch engaging a detent 5 on an offset part of the strut section 2. A jack 6 pivoted to the same pin as the section 2 has a ram 7 with a notched end engaging a pin 8 on an offset member on the section 3. An offset part 7b on the ram is connected by a link 9 to the latch 10 the link being extensible to allow the latch to snap over the detent but acting positively under compression. Initial movement of the ram 7 to retract the undercarriage consequently first disengages the latch and as the parts fold, the latch assumes the position shown in broken lines and snaps over a detent 5<1> on the aircraft frame. Initial movement of the ram to lower the undercarriage releases the catch. Specification 486,936 is referred to.
