Title: Improved pipe coupling
IPC: F16L37/12
Filed: 1968-05-24
Abstract: 1,217,781. Pipe couplings. HYDRASEARCH CO. Inc. 24 May, 1968 [26 May, 1967], No. 24824/68. Heading F2G. A coupling for connecting conduits 11, 12 comprises a tubular nipple 14 secured to the conduit 11 and having a flange 17 including a radially extending face 18 on which sealing means 20 effects a seal between the face and a flange 13 on the conduit 12, and a plurality of clamps 30 each carried by the nipple and terminating in a hook 34 adapted to engage the flange 13. There are pivot means for each clamp and also mounting means 31 interconnecting each clamp with the pivot means for pivotal movement of the clamp about an axis transverse to the longitudinal axis of the nipple from a first position, in which the hook portion is radially outward beyond the periphery of the flange 13, to a second position in which the hook portion overlies and engages the flange. Retaining means carried by the nipple and engageable with each clamp inhibit movement of the clamp from the said second position. The mounting means interconnects each clamp with the pivot means 42 to permit longitudinal movement of the clamp relative to the pivot means, and there are means to effect longitudinal movement of each clamp when in the second position in a direction substantially parallel to the axis of the nipple. As shown, in Fig. 5, the hooked ends 34 of the clamps are carried on shafts 33 which extend through the mounting means 31 which are pivotally connected by links 40 to pivot pins 42 provided with eccentrics 46 and camming surfaces, the pins 42 being connected to locking handles 48. To facilitate alignment of the pipe 12 and nipple 14, the latter has axially projecting lugs 51. In operation, the handles 35 are pressed downwardly, the flanges 13, 18 being brought into alignment and the clamps being then pushed downwardly so that the hooked ends 34 assume the positions 34a; the slotted recesses 38 are received between the legs of the bifurcations 55b and engaged by resiliently biased balls 61. By turning the handles 35 the hooked ends 34 are brought into engagement with the flange 13, after which rotation of the handles 40 causes rotation of the eccentrics 46 so that the ends 34 are pulled tightly against the flange 13. Stops 49 on the links 40 prevent over rotation of the handles 48. In a modification, the hooked end 134, Fig. 11, of each clamp is connected to an hydraulic piston-cylinder unit 136 which draws the hooked end into engagement with the flange 13, the clamps being raised radially by hydraulic piston-cylinder units 157 for alignment of the nipple 119 and pipe 112.

Title: Catalytic reforming of hydrocarbons
IPC: C10B/
Filed: 1965-06-11
Abstract: 1,109,296. Catalytic steam-reforming hydrocarbons. OFFICE NATIONAL INDUSTRIEL DE L'AZOTE. 11 June, 1965 [3 July, 1964], No. 24834/65. Heading C5E. In the catalytic steam-reforming of hydrocarbons (except methane) to produce a methanerich gas, heat is provided by supplying a hydrogen-containing gas to the reaction to react exothermically with carbon oxides (to produce methane). The reaction is carried out at 450‹ to 550‹ C. and at 1 to 50 kg./sq. cm., and the flow rates of hydrocarbon, steam and hydrogen-containing gas are controlled to give an autothermic (or exothermic, if desired) reaction. The catalyst may be Ni and/or Co, or a Pt group metal on a refractory support. In an example, light petrol vaporized by superheated steam was mixed in the reactor with a gas (67% H 2 ), all reactants being preheated to 430‹ C., and the mixture reacted over a Ni/Pt catalyst. The product gas (57À9% CH 4 ) was methanated with H 2  at 320‹ C. to 95À6% CH 4 .

Title: Improvements in the manufacture and production of motor fuels
IPC: C10L1/06
Filed: 1928-08-29
Abstract: 325,858. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Aug. 29, 1928. Motor spirit is made by blending a hydrocarbon oil fraction with a tendency to knock and boiling up to about 150‹ C. and for the most part below 120‹ C., with an anti-knocking 120-185‹ C. hydrocarbon oil fraction rich in unsaturated or aromatic hydrocarbons and obtained by (1) distilling aromatic tars, aromatic petroleums, and the like; (2) the condensation of unsaturated compounds; (3) the destructive hydrogenation or dehydrogenation of aliphatic or hydroaromatic compounds, e.g. as described in Specifications 293,906, [Class 1 (i), Chemical processes &c.], and 302,253, [Class 32, Distilling &c.]; (4) the destructive hydrogenation of aromatic middle oils e.g. anthracene oils, coal tars, coal tar products, or cracking residues; or (5) sulphur dioxide extraction. For example, (1) the 120-185‹ C. fraction of a knocking fuel boiling up to 185‹ C. is replaced by one of the above anti-knocking fractions. (2) 3 litres of straight run Pennsylvanian gasolene boiling up to 150‹ C. are mixed with 1 litre of a 140-180‹ C. fraction obtained by treating Coastal gas oil with hydrogen at 560‹ C. and 200 atmospheres in presence of a ferrosilicon catalyst.

Patent GB-484472-A (GB)
Title: Improvements relating to the mounting of electrical contacts for telegraphic relays
IPC: H01H50/54
Filed: 1936-09-11
Abstract: 484,472. Electromagnetic relays. CARPENTER, R. E. H. Sept. 11, 1936, Nos. 24859 and 31879. [Class 38 (v)] An electric telegraph relay has one or more of its contacts mounted with compliance accompanied with heavy damping in such a. way as to damp out vibrations of the contacts and to enable substantially the whole travel of the armature between the side contacts to be accounted for by the compliance or yielding of the contacts. As shown in Fig. 1, the armature 3 is suspended on a blade spring 4 and is provided with contacts 5 on opposite sides. These contacts engage with contacts 9 mounted on springs 10 attached to cup members 8 mounted on adjusting screws 6. As the contacts 5 move to left or right the springs 10 are depressed into the cup-like members 8 mounted on screwed rods 6. The springs are each riveted to the saucer-like members 8 and the platinum contacts 9 are mounted thereon. As each relatively-fixed contact is engaged the spring blade moves into the saucer-like depression of the member 8 so increasing the sum of the contact gaps. The gaps between the contacts may be adjusted so that the transit time of the relay is made vanishingly small, i.e. so that the armature contact or moving tongue breaks with one side contact practically simultaneously with making with the other side contact. At the same time it is not essential to operate the relay with such an adjustment which provides the possibility of a short-circuit between the side contacts of infinitesimal duration at each swing of the armature since the relay may be still made to work satisfactorily when sufficient gap is left to prevent the short circuit. Such a short-circuit of brief duration is, however, of no importance since protective resistances may be ordinarily connected in the leads to both side contacts 9, Fig. 5 (not shown). In a modification, the contacts are each carried on a sheet of metal gauze, Fig. 8 (not shown). Specification 315,496, [Class 38 (v)], is referred to.

Title: Improvements relating to hydraulic transmissions
IPC: B60W10/10
Filed: 1969-05-16
Abstract: 1,269,141. Hydrostatic transmission. INTERNATIONAL HARVESTER CO. 16 May, 1969 [23 May, 1968], No. 25090/69. Heading F2D. In a vehicle hydrostatic transmission having by-pass valve means preventing excessive pressures during overrunning to prevent overspeeding of the pump and engine, an anti-coast valve 139 is operative in forward only to prevent complete by-pass of fluid during overrunning to maintain engine braking effective. The transmission comprises a pump and a motor of the variable-stroke swash-plate type having by-pass relief valves 19, 19A between their pressure and return lines. The valves have spring-loaded spools 38, 38a subject to the pressure in a line 18a, 18 acting via a line 20, 20a and connected to a respective transmission line. Passages having restricted orifices 48, 47 and 48a, 47a are provided in the valves and lead via lines 46, 46a to chambers between relief valves 82, 93 and 82a, 93a which are connected by the anti-coast valve 139 and a line 50 to a manually-adjusted spring- loaded pilot relief valve 52. Valves 82a and 93a are selectably unseated, according to the direction in which the transmission motor is to be driven, by a slidable cam 117 acting through push rods 107, 106a, and positioned by an F-N-R lever 118. In neutral, push rod 107 is raised by land 135 on cam 117 to open valve 93a and, through push rod 106a, to open valve 82a. In forward gear, the rod 107 abuts reduced diameter portion 133 and is raised sufficiently to open valve 93a but not valve 82a. In reverse gear, the rod 107 abuts portion 134 and both valves remain closed. Under normal drive in forward gear, line 46 carries high pressure acting between valves 82, 93 to open valve 82 and force spool 140 of anti-coast valve 139 down so that the high pressure may be regulated by the relief valve 52 which relieves excessively high pressure or allows the transmission to be brought into neutral by depression of pedal 76. On overrun, high pressure in line 46a acts on the spool 140 via the open valve 93a and a passage 111, to raise the spool and close line 50 preventing complete by-pass. The pressure also acts to open valve 93 thus reducing the pressure acting on the rear of spool 38a which is thereby shifted to interconnect the lines 18, 18A to reduce the excess pressure. In reverse, during normal operation, high pressure in line 46a opens valve 82a and forces spool 140 down to open line 50. Similarly on overrun, high pressure in line 46 opens valve 82 and holds spool 140 down. High pressure is thus regulated by only the pilot relief valve 52 during reverse. Depression of pedal 76 will again neutralize the transmission, and may also be used to provide smooth power take-ups. A shuttle valve (24), Fig. 1 (not shown), is opened by high pressure to direct low make-up pressure from an engine-driven pump (12) for cooling.

In a tubeless tyre wheel rim comprising a rim base 1 with an integral tapered bead seat 3 and tyre retaining flange 2 at one side, and a gutter 4 at the other side in which is received a locking ring 12 to retain a detachable endless tyre bead seat and retaining ring 8, the locking ring 12 comprises an endless extensible metal core embedded in rubber-like resilient material 14 which extends laterally from the core as at 15, Fig. 4, to be compressed, and effect an airtight seal between the side ring 8 and rim base 1. As shown the core may comprise either an annulus of closely spaced helical turns 13 of spring steel wire, Figs. 3 and 4, or an endless open-braided tube 17, Fig. 5, of metal wire or ribbon 18. The rubber-like material may be vulcanized to the core to provide a thin surface coating thereon, and the side ring 8 may have an arcuate groove 11 to engage the locking ring on assembly of the wheel.

Filed: 1970-05-26
Abstract: 1,237,850. Deflecting propulsive jets. ROLLSROYCE Ltd. 26 May, 1970, No. 25200/70. Heading B7G. A ducted fan gas turbine engine for effecting forward propulsion of an aircraft has means for moving a pivotable member disposed at or adjacent the rear of the engine into and out of an operative position, such that when the member is in this position, at least part of the efflux gases of the engine are upwardly directed by the pivotable member on to a lift-increasing flap member (or members) in order to assist landing and take-off of the aircraft. In one embodiment, a ducted fan gas turbine engine 14 has a pod 11 forming the outer casing of the fan duct 13 and an inner casing 15, the downstream end of which forms an exhaust duct 16 for the turbine exhaust gases. A part 17 of the exhaust duct 16 is mounted on pivots 18 and is movable (by a ram, not shown) into and out of an operative position (indicated in broken lines) in which part of the fan air passing through the fan duct 13 will be upwardly directed by the part 17 on to lift-increasing flap members (not shown). By this means the take-off run of the aircraft is considerably shortened, while when the aircraft is landing, its stalling speed is considerably lower. In an alternative embodiment (Figs 6 to 8, not shown), the fan duct is bifurcated at its downstream end into two branches, the fan air passing to atmosphere through two pivotable nozzles mounted at the downstream ends of the branches and so directed as to flow over lift-increasing flap members.

Abstract: 665,797. Hand-operated brakes. DAIMLERBENZ AKT.-GES. Oct. 4, 1949 [Oct. 1, 1948], No. 25545/49. Class 103 (i). Brake operating means comprising a column movable axially for applying or releasing the brakes and rotatable for locking or unlocking it in or from a braking position, is distinguished by the column being guided by means permitting it to oscillate about an axis substantially parallel with the pivot axis by which it is jointedly connected with brake linkage. The brake-operating column comprises two parts, an upper tubular part 5 having a handle 7 attached thereto and a lower solid part 4 pivoted at 8 to a lever 9 of the brake linkage. The upper extremity of the part 4 is formed with a collar 15 which fits within a recess in a sleeve 12 fast with the end of the tube 5. A further sleeve 13 is pinned to the part 4 and the interengaging faces of the sleeves are formed with projections 17 which permit a limited amount of relative rotation between them. The upper end of the part 5 is slidably mounted in a collar 6 attached to the dashboard 1 and formed with a radiused seating 20 which permits the column to rock about a theoretical axis B under the action of the arcuate movement of the lever 9. A tubular projection 21 formed on the collar 6 houses a pawl 23 urged by a spring 22 into engagement with a rack 24 formed on the part 5. The teeth of the rack are shaped to run out into the outside diameter of the tube so that by rotation of the handle 7, the rack can be disengaged from the pawl 23 to permit free axial movement of the operating column.
