Patent GB-782944-A (GB)
Title: A method of press-forming hollow members
IPC: B21K21/08
Filed: 1955-05-31
Abstract: 782,944. Extruding; forging. BOSCH GES., R. May 31, 1955 [June 11, 1954], No. 15518/55. Classes 83 (2) and 83 (4). Making sparking-plug casings. A method of making hollow members with stepped walls, more particularly sparking-plug casings, comprises forming a cup-shaped blank 21, Fig. 3, with internal and external stepped surfaces in the region of its mid-length, backwardly extruding the solid base portion 16 of the blank by means of a ram 28 and in a separate subsequent pressing stage, forwardly extruding the head portion at the other side of the stepped surfaces by means of a ram 38, Fig. 4, to form the blank 40, whereby the axial length of the blank is extended on both sides of the stepped surfaces. In the manufacture of a sparking-plug casing, a blank 1, Fig. 1, cut from cylindrical bar stock, is inserted in a die 2 yieldably movable against springs 3, and supported therein against an ejector 5. A ram 6 with a conical nose 7 is pressed into the blank whilst simultaneously an annular pressure member 8 pushes the die forward against its springs, the ejector remaining stationary. The blank is thus pierced and enlarged laterally to cup-shape. The blank is then annealed and phosphated. It is then inserted in a second die 11, Fig. 2 (not shown), in which it is elongated by a ram pressed into the bore of the blank, and the stepped surfaces are formed internally and externally at the mid-length of the blank; the latter now has the shape 21, Fig. 3. The blank 21 is then inserted in the die 23 within which the centre and head portion of the blank are slidable. The base portion is closely fitted in a cylindrical die section 24 closed by an ejector 26. The ram 28 having an enlarged collar 29 is then pressed into the base portion 16 to backwardly extrude the latter, the centre and head portions sliding backwardly unchanged. The ejector 26 carries a boss 27 which forms a recess 30 in the end of the extruded blank 31. The ejector 26 and a stripper plate 32 remove the blank from the die 23. After insertion in the next die 33, Fig. 4, a mandrel 37 is fitted into the blank, and the head portion thereof is extruded forwardly by an annular ram 38; the mandrel moves forwardly with the ram during the extrusion. An ejector 36 removes the extruded blank 40 from the die. The blank is then inserted in a further die 42, Fig. 5 (not shown), a mandrel is passed into the bore of the blank and an annular ram presses on the open end of the blank to form the head 39 thereof into hexagonal cross section; the casing may also be pressed to size during this operation. The disc of metal remaining in the closed end of the blank is then removed by a punch 52, Fig. 6 (not shown), the end of the hexagonal head is turned down by a cutting tool 56, Fig. 7 (not shown), and a thread cut on the base portion of the casing. The surfaces of the plug may then be phosphated, coloured or provided with a rust-protecting coating. The various pressing operatsions are preferably performed cold on a five-stage press.

Class 99 (i) The shank 18 of a spigot 10 is connected by threads 20 to a coupling body 12 and has in the region of the threads a frusto-conical bore portion which is expanded by a suitable tool to provide full-bore flow and to distort the threads to a tapered form so that the spigot and body are interlocked, the hose 15 being gripped between the expanded shank 17 and a ferrule 11. The body may abut an inward ferrule flange 23 which engages in a spigot groove 19 and the shank 18 may be internally or externally threaded or provided with a rotatable nut or annular teeth for connection to a complementary coupling part or hose end. A spigot having tapered threads 20 may be provided when the body and ferrule are salvaged from a damaged coupling for re-use.
Patent GB-549070-A (GB)
Title: Improved steering device for endless track vehicles
IPC: B62D11/10
Filed: 1941-12-03
Abstract: 549,070. Driving and steering endless-track vehicles. BOUNSALL, H. R. Dec. 3, 1941, No. 15549. Addition to 539,079. [Class 79 (ii)] Each track sprocket H of an endless-track vehicle is driven through a separate epicyclic reducing gear of which the sun pinion B is positively driven through bevel gearing A from the gear-box S, the toothed annulus K is fixed to the sprocket, and the planet carrier E is normally held stationary by a brake O. Steering is effected by slowing down the drive on the side to which the vehicle is to turn, and for this purpose the brake O on that side is released and the corresponding planet carrier E is driven through a differential gear in the required direction. In the construction shown the differential gear is driven from the gear-box S when a clutch T is engaged, and one brake O being released while the other is still applied, one differential shaft remains stationary but the other is driven and slows down the drive to one track sprocket, the other sprocket being positively driven at its normal speed. Two steering levers are provided, each acting in succession on one brake O and the clutch T. Free-wheels W are provided on the differential shafts and permit the latter to run in one direction only. Thus, the sprocket on the side where a brake O is released cannot over-run or rotate faster than the other sprocket and the defect of so-called "reverse" steering is not possible.

Title: Improvements in valve-operating mechanism
IPC: F16K31/48
Filed: 1943-09-23
Abstract: 571,710. Gas purifier valves. DEMPSTER, Ltd., R. & J., SHEERAN, A. J., and SAVAGE, W. A. Sept. 23, 1943, No. 15645. [Class 55 (ii)] [Also in Groups XXIV and XXIX] Each of the six main valves of an absorption filter plant for recovering benzol from retort or still gases is operated by a diaphragm actuated by pressure fluid controlled by a pilot valve which is actuated from an operating shaft driven from a slow-motion shaft, the arrangement being such that, during each quarterrevolution of the operating shaft, the pilot valve is first rotated through a small angle at slow speed and for the remainder of the quarterrevolution, at high speed due to the temporary coupling of the operating shaft to a high-speed shaft, the pilot valve thereafter being stationary until the drive of the slow-motion shaft is resumed. The fluid-pressure diaphragm is controlled by a rotary plug valve 10, Fig. 1, actuated from a shaft 14 through bevel gears 13. Loosely mounted on the shaft 14 is a wheel 16 carrying four spaced sets of teeth 161 and driven by a dog 25 which engages between the spokes of the wheel 16. The dog 25 is carried by a worm-wheel 23 driven by a slowly rotating worm 22. When one of the sets of teeth 161 reaches and engages a pinion 19 driven from a fast-motion shaft 21, the wheel 16 is spun quickly and this movement is transmitted from the diametrically opposite set of teeth 161 through pinion 17 and. gearing 182, 181 to the shaft 14, and the movement of the latter actuates the valves 10. In a modification, the shaft 14, Fig. 4, carries a ratchet wheel 30 which has a lost-motion connection with the slowly rotating worm-wheel 23 through a dog clutch 38, 39. The fast-motion shaft 21 actuates an oscillating pusher 33 which normally moves between one of the curved surfaces 301 of the ratchet wheel and a guide 36. When one of the recesses 31 is presented to the pusher, the ratchet wheel is given a quick movement which actuates the valves.

Abstract: 924,900. Overhead conveyers. GEO. W. KING Ltd. May 2, 1961 [May 4, 1960], No. 15755/60. Class 104 (2). In a conveyer system, in which trolleys 11 are propelled along a track 10 in the direction X by dogs 12 on attachments 14 depending from an endless driven chain 13, the dogs 12 are pivotally mounted on the attachments 14 and are provided with pawls 19, which, when in their operative position, as at the station C in Fig. 1, prevent the dogs 12 from pivoting rearwardly, so that they engage with the trolleys, and when in their inoperative position, i.e. at the station A in Fig. 1 allow the dogs 12 to ride over the trolleys 11. The chain 13 is supported by trolleys 15 running on a track 16, and the dogs 12 are alternated with retaining dogs 17, which prevent the trolleys from moving faster than the chain e.g. on a downward slope. The pawls 19 are normally in engagement with recesses 18 in the dogs 12 and means is provided for tripping the pawls out of the recesses 18 in order to stop the trolleys at predetermined positions on the track 10, e.g. the stations A, B, C in Fig. 1. At the station A in Fig. 1 a frame member 20 is provided, hinged at 21 on an axis which is at an angle both to the horizontal and to the direction of travel of the trolleys 11, the member 20 normally hanging clear of the trolleys. A solenoid (not shown) is provided, which, when actuated, moves the member 20 so that a cam element 22 on the member 20 is held in the path of pegs 23 projecting from the pawls 19. The next pawl 19 to pass is then tripped and the dog 12 released from driving engagement with its trolley 11. Succeeding pawls 19 are also tripped by the element 22 and the trolley 11 is held at the station A by the front end of the frame member 20 and by a stop 24 which is pivotally mounted to allow passage of the trolleys in the direction X only. In order to prevent a pile-up of trolleys 11 whilst the one is held at the station A, the succeeding trolleys are held at stations B, C by similar frame members 20. The trolleys 11 engage with pivoted levers 26, 26<SP>1</SP>, these levers being fixed to links 27, 27<SP>1</SP> respectively, which in turn are connected to rods 28, 28<SP>1</SP> serving to pull the frame members 20 at the following stations into their operative positions through the actions of springs 29, 29<SP>1</SP>. The members 20 may be replaced by switch or lever-operated cam elements.
Patent GB-1101922-A (GB)
Title: Improved process for preparing amines
IPC: B01J25/00
Filed: 1965-04-13
Abstract: A compound containing an aliphatically bound primary or secondary hydroxyl radical, the hydroxyl radical being attached to a carbon atom which is non-vicinal to a carbon atom carrying hydroxyl or phenoxy, is converted to an amine by ammonolysis with ammonia or a primary or secondary amine at 150-275 DEG  C. in the presence of a Raney type metal hydrogenation catalyst comprising nickel and chromium. The catalyst may be prepared in conventional manner from a Ni-Al-Cr alloy, e.g. one containing from 45 to 65% Al, 34 to 50% Ni and 1 to 5% Cr.  The compound containing the hydroxy radical may be e.g. ethanol, n-propanol, isopropanol, n- or sec-butanol, isobutanol, n-amyl alcohol, 1- or 2-octanol, cyclohexanol, tridecyl-, oleyl-, or stearyl alcohol, benzyl alcohol, 2-phenyl ethanol, a polyhydric alcohol, e.g. an appropriate diol such as 1,3-propanediol, diethylene glycol, higher polyethylene glycols, di- and tri-propylene glycols, and appropriate oxyalkylene derivatives of various alcohols, phenols and amines.  Specified aminating agents are ammonia, methyl-, dimethyl-, ethyl-, diethyl-, n-butyl, sec.-butyl, isobutyl-, 1-octyl-, n-dodecyl-, and octadecyl amines, morpholine, pyrollidine, piperidine, piperazine, ethylene diamine, diethylene triamine, and benzyl amine. The reaction is generally effected in the absence of an inert solvent or diluent, but if desired an inert solvent or diluent, e.g. a tertiary alcohol, an ether, an aliphatic or aromatic hydrocarbon, or a non-reactive tertiary amine, e.g. pyridine, picoline or lutidine, may be present.  Water may also be present in minor amount.  The reaction is generally carried out under pressure and may be operated batchwise or continuously.  An excess of ammonia may be used, especially when it is desired to form primary amines. Examples are given for the production of n-butyl amine and di-n-butyl amine from n-butanol and ammonia, and for the production of amines from ammonia and polyoxyethylene (6) tridecyl ether, triethylene glycol and polyoxyethylene (4) phenol respectively, using a Raney type Ni-Cr catalyst prepared from a Ni-Al-Cr alloy containing by weight 58% Al, 39.5% Ni and 2.5% Cr.
