Title: Improvements in the manufacture and production of organic halogen-sulphonic acid chlorides
IPC: C07C309/65
Filed: 1938-07-28
Abstract: 516,214. Halogen sulphochlorides. JOHNSON, G. W. (I.G. Farbenindustrie Akt.-Ges.). July 28, 1938, No. 22501. [Class 2 (iii)] Halogenated sulphonic acid chlorides, which may contain more than one sulphochloride group, are prepared by acting with a mixture of sulphur dioxide and chlorine during irradiation with short-wave light, preferably shorter than 2,200 Angstrom units, in the liquid phase on halogen hydrocarbons containing in the molecule at least one carbon atom to which is attached at least one hydrogen atom but no halogen atom, preferably at temperatures below 50‹C., e.g., 0‹-20‹C. Initial materials specified are 1- or 2-monochlorpropane, 1- or 2-mono-chlor-normal-butane and its isomers such as monochlor-isobutanes, 1.2-dichlornormal-butane, dichlordodecane, monobromoctadecane and cyclic halogen hydrocarbons such as cyclohexylchloride; the halogenated hydrocarbons may also contain non-halogenated hydrocarbons and mixtures of different halogeen hydrocarbons may be used, e.g., halogenated hydrocarbons formed by the action of halogen on the hydrocarbons obtained by the catalytic hydrogenation of carbon monoxide at ordinary or moderately increased pressure. The reaction may be carried out under pressure, and, especially in the case of solid or very low boiling halogen hydrocarbons, in the presence of solvents such as halogen hydrocarbons containing one or more halogen atoms on every carbon atom, e.g., carbon tetrachloride or ethylene chloride. The mixture of chlorine and sulphur dioxide which may contain equal volumes of each or which may have an excess of sulphur dioxide, may be lead through dispersing means provided at the bottom of a vessel, e.g., of enamelled iron or ceramic material, in which the initial material is situated, while irradiating with short wave light, e.g, by using a mercury vapour lamp, or by passing the light through a window of quartz or of a glass permeable to ultra-violet light. In examples, (1) chlorbutane sulphonic acid chloride, along with some 1.2- and 1.3-dichlorbutane, is obtained by passing chlorine and sulphur dioxide into 1-chlor-normal-butane for 7 hours, (2) cyclohexane sulphonic acid chloride is obtained from cyclohexyl chloride by the method of example (1), (3) chlorinated hydrocarbons having an average chlorine content of 9.1 per cent. obtained by chlorinating a hydrocarbon mixture having a boiling range of 200‹-350‹C. is reacted in the manner described in example 1 ; 1:2 dichlor-normal-dodecane and' a chlorinated hydrocarbon prepared from a hydrocarbon oil having a boiling range of 200‹-350‹C., are similarly treated.

Title: Improvements in and relating to gyroscopic apparatus
IPC: G01C19/02
Filed: 1956-07-20
Abstract: 836,817. Ammunition. COMMONWEALTH OF AUSTRALIA. July 20, 1956 [July 21, 1955], No. 22571/56. Class 9(2) [Also in Group XX] A gyroscope driving means comprises a clock spring means for coupling it to the gyroscope rotor, and means for uncoupling it from the rotor as it unwinds. The gyroscope shown comprises a cylindrical housing 11 in which a gyro rotor 15 e.g. as described in Specification 836,816, is mounted on gimbals and a cylindrical housing 17 attached to housing 11 with its axis at right angles to that of housing 11 and passing through the centre of rotor 15. The ends of a spiral spring are secured to housing 17 and to a cylindrical arbor 20 respectively and an internally threaded sleeve 22 forms a close fit in the arbor. Threaded in this sleeve is a nut 24, and this nut and the lower wall 21 of arbor 20 have squared holes accommodating a shaft 25 to which a ratchet 28 is attached. This shaft has a slot 32 for engagement by a key to wind up spring 18 and, at its lower end, a slot for engagement by a tongue 16 on the gyro rotor 15. Ratchet 28 is held fast to prevent unwinding of spring 18 by a pivoted pawl 29, spring urged at 49 so that the tail of the pawl engages a pin 34 carried by a piston 37 slidable in a cylinder 35 and adapted to be forced downwardly on fixing a matchhead of the type used for igniting rockets. This releases the ratchet 28 with the result that the spring 18 runs down and in doing so accelerates the rotor 15 up to its operating speed. As the spring runs down, the nut 24 moves upwardly and engages the ratchet boss 27 so as to raise shaft 25 and thus disengage the rotor 15. When this occurs a contact 39 overhanging ratchet 28 moves into engagement with conduit 40 and closes the firing circuit for the rocket motors of the missile in which the gryo is incorporated. There is also provided a pair of normally open contacts- 41, 42 controlled by a pivoted lever 43, movable by turning a key from a safe position, in which lever 43 engages a pin 47 and is positioned to prevent a release movement by pawl 29, to a position in which contacts 41, -42 are closed and the matchhead firing circuit is operated.

Title: Improvements in or relating to apparatus for rolling metal strip
IPC: B21B1/32
Filed: 1936-08-17
Abstract: 470,216. Rolling. WILLIAMS, W. P. (American Rolling Mill Co.) Aug. 17, 1936, No. 22666. [Class 83 (iv)] In a repeat strip-rolling mill the strip tension is controlled by mounting each coiler 76 on a cradle 78 tiltable about pivots 82 by fluidpressure cylinders 84, 85 so urging the coilers away from the mill under constant forces to take up sporadic variations in elongation. When the mill is reversed it will cause automatically a greater fluid pressure in the cylinder 84 than in the cylinder 85 by providing a separate accumulator for each cylinder and changing the effective weight on the accumulator by tilting them automatically about trunnions 99, Fig. 2. The coiler 76, Fig. 3 (lower part) is braked by friction cables 121 on a drum 120 through the gear-box 116 to the coiler. The braking is kept constant by a loaded scale beam 125, Fig. 9, pulling up one end of the cable 121, a weight 130 on the scale beam being automatically moved along the scale beam 125 by a reversible motor 128 switched on as required by the rocking of the cradle 78. The braking can be relieved during the threading through the work by a hand-operated scale beam lifter 131. The brake drum 122 is provided with an overrunning clutch which renders the brake ineffective when the coiler is being positively driven by its motor To move the drum for loading or re-winding, it can roll along the cradle by means of grooved rollers on its shaft ends. The forward and back tensions on the work are measured by the angular displacement of the hydraulic cylinders about their trunnions 99 and shown on suitably calibrated indicators 109 moved by flexible shafts, or by a Selsyn generator and motor.

Inventor: GEARY WILLIAM RICHARD CLIFFORD
IPC: A01F15/07
Filed: 1968-05-14
Abstract: 1,218,647. Hay harvesters. W. R. C. GEARY. 14 May, 1968 [15 May, 1967; 11 Dec., 1967], No. 22742/68. Heading A1F. [Also in Division B5] A hay harvester which is drawn along a previously cut swath comprises transverse rotatable winding means around which the swath is wound as the machine advances to form a roll, the winding means being vertically movable to conform to the diameter of the roll, and means being operable to withdraw the winding means from the finished roll. A wheeled frame 10 provided with a tractor hitch point 14 carries lifting arms 16 pivoted at their forward ends to a spindle 18 and connected at their free ends by a beam 20. The arms 16 carry brackets 29 to which long main arms 26 are pivotally connected by pins 28; a hydraulic cylinder unit 22, acting vertically on a bracket 24 carried by the beam 20, and a further hydraulic cylinder unit 32, acting on the arms 26 and supported by a sleeve 30 freely mounted on the spindle 18, respectively produce vertical and inward/ outward movement of the arms 26. A detachable freely rotatable swath winding device 34 is mounted at the end of one arm 26, the other arm supporting a driving disc 38, engageable with the device 34 when the arms 26 are swung inwards. A vertically adjustable sub-frame 42 pivoted on a spindle 43 and having skids 48 carries a driven swath pick up roller 50, the swath being compacted between the roller 50 and a second roller 54 as the machine advances. Twine 58 from reels 63, or protective sheet material, e.g. polythene, applied towards the end of the process from a roll 68 may be paid out beneath the swath as it is returned to the ground, strengthening it as it is finally picked up and reeled on to the device 34, attachment of the initial end of the swath to the winder being achieved by swinging the device 34 inwardly around the end of the swath. When the rolled swath 37 reaches the required diameter the device 34 is progressively withdrawn. In an alternative construction, Figs. 6-7 (not shown), only that arm 26 carrying the device 34 is directly operated by the hydraulic cylinder 32, an optional linkage (27) transmitting the movement to the other arm 26. Further, each arm 26 may be fitted with a similar driven swath engaging member, or stubs (72) may be provided for transporting completed rolls 37. For use as fodder, rolls 37 may be unwound, Fig. 8 (not shown), the twine being re-wound on to spools (73) for re-use.

Title: Improvements in operating gear for automatic slack adjusters of vehicle brakes
IPC: B61H15/00
Filed: 1939-08-08
Abstract: 531,936. Adjusting brakes. SVENSKA AKTIEBOLAGET BROMSREGULATOR, and BROWALL, B. H. Aug. 8, 1939, No. 22881. [Class 103 (i)] Relates to operating means for automatic slack-adjusters that act both to increase and decrease slack and are arranged as at 7 in one of a pair of pull-rods 5, 40 connected to levers 2, 4 linked together as at 3 and operated as by a cylinder 1. In adjusters of this kind and as described for instance in Specification 418,492, the rod 5 is in two parts relatively slidable under the control of a casing 7 slidable on the rod and adapted to be moved in one direction at brake application against the action of a spring 8 and in the other direction at brake release. In order to reduce the reaction of the spring 8 on the brake piston, the operating rod 9, for the casing 7, in the arrangement shown in Fig. 1, instead of being connected to the lower end of the lever 4 is connected to a lever 11 linked by a rod 12 to the lever 2 so as to increase the leverage. As shown, the levers 2, 4 are adapted selectively to be connected by either of two links 3, 3a to vary the brake applying leverage according to the vehicle load. In Fig. 4, the operating rod 9 for the casing 7 is connected to the lever 4 but operates the casing through a lever 13a pivoted to the casing at 21 and bearing by a roller 22 on the rod 5 so that the leverage is increased. The increase of leverage reduces the extent of movement of the casing and thus of the slack reduction at a single brake operation and in order that an abnormally excessive slack may be reduced at one brake operation the lever 13a may be adapted to engage a projection 25 on the casing. after a predetermined movement so that it then has the same movement as the rod 9. The lever 13a may be arranged to abut on the flange 23 on the rod 5 below the pivot 21 near the end of the release movement so as to move the casing 7 relatively to the rod 5, sufficiently to lock the adjuster against slack-increasing action due to shocks. In a further arrangement, the lever 13a is so shaped that it ceases to be moved by the rod 9 after a pre-determined movement.
