Abstract: 951,149. Toothed gearing; screw and nut mechanisms; gearing for stopping machinery. DRAYTON CONTROLS Ltd. Oct. 24, 1962 [Nov. 6, 1961], No. 39580/61. Headings F2L and F2Q. An axially movable worm 32 engaged by a toothed wheel 34 imparts linear motion to an actuating member by two relevant modes of combined working between the worm and the wheel. In one mode of working, the worm is rotated by a handwheel 36 and splined shaft 35, while the worm-wheel 34 is held by the irreversibility of a second worm 38, thus providing a screw-and-nut action of the worm to actuate a fluid valve. In the other mode of working the worm 38 is driven by an electric motor 37 to rotate the wheel 34 and provide a rack-and-pinion operation of the worm 32. The worm 38 is carried in axially movable bearings 41, 42 engaged by levers 47, 50 pivoted on the main casing and loaded by a spring 51. When the actuated member reaches either end of its travel the increased axial loading of the worm 38 causes either lever 47 or 50 to rock and open a relevant microswitch 53, 55 to stop the motor. In a second embodiment the worm 32 is driven by the motor and the worm 38 by the hand wheel; the worm 38 being swingably engageable with the worm wheel which is held by an electromagnetic brake in circuit with the motor. Limit switches are provided for the worm 32. The mechanism in its most simple form is described and shown in the Provisional Specification.

Abstract: 1,047,568. Convertible aircraft. WESTLAND AIRCRAFT Ltd. Sept. 3, 1964 [Oct. 9, 1963], No. 39743/63. Heading B7W. In a convertible aircraft, and to take account of the different characteristics of the rotor that are necessary with its axis vertical for take-off and landing and with its axis horizontal for forward flight, each rotor blade 31 (Fig. 5, not shown) is secured by its root rib 32 to a torque tube 33 which houses bearings for a torsion member 34 which is secured at its root end to the rotor head and at its outer end to a rib 39. The tube 33 carries an arm 35 connected by a link 36 to the collective pitch controlling mechanism and the blade is so constructed as to provide predetermined torsional flexibility along its length, so that the variation in pitch of the blade varies from a maximum at the root to a minimum at the tip in dependence on the aerodynamic loading of the blade and the propeller movement, such effect being considerably greater during landing and take-off than in forward flight. In a further embodiment the torsional flexibility of the blade is relied upon to achieve the desired result and in another embodiment the leading edge of the blade is formed by a hinged flap which has an outboardlydecreasing chord, the flap being connected by gearing to the non-rotating part of the blade root member so that when the blade is at minimum pitch and the leading edge member is depressed the mean chord at the root is substantially parallel to the chord line at the tip. Consequently when pitch is increased, as for take-off, the flap chord is automatically aligned at the root with the blade chord thus providing a decreasing pitch outwardly along the span of the blade.

Abstract: 1,218,709. Winding webs. HOBEMA MASCHIKENFABRIK HERMANN H. RATHS. 8 Aug., 1969 [9 Aug., 1968], No. 39882/69. Heading B8R. A web-winding machine comprises a plurality of winding shafts 8 carrying cores 17 upon which a web 9 is to be wound into rolls 15, the shafts 8 being mounted between two spiders 1, 2 which are of different diameters and which are connected by a shaft 18 so as to be indexable about a common axis. The spider 1 of larger diameter is formed with a series of radial slots (3a to 3b), Fig. 2 (not shown), each of which receives one end of a respective winding shaft 8 whilst the other end of each shaft is received by a corresponding slot 4a to 4b formed in individual cullis blocks 5 arranged around the spider 2 of smaller diameter, the blocks 5 being mounted so that they can move radially of the spider 2. The ends of the winding shafts 8 are further supported by guide rails 26a, 27a, 28 fixed on the machine frame 19a adjacent spider 2 and by guide rails (26b), (27b) fixed on the frame 19b adjacent spider 1. The cullis blocks 5 are provided with guide rollers 6 which co-operate with a cam 7 fixed to the frame 19a, this cam controlling the radial movement of the blocks 5 during the indexing of spiders 1, 2. Thus, starting from the position characterized by slots 4e, (3e) a winding shaft 8 carrying a core 17 passes through the rest position 4f, (3f) as the spiders 1, 2 are indexed in the direction of arrow 20, into a station 4g, (3g) where the core 17 is cut into individual sections and provided with lines of glue; then the shaft 8 is accelerated up to the required winding speed in station 4h, (3h) before passing to the winding station 4a, (3a). The web 9 to be wound comes from a supply reel (not shown) and is slit longitudinally by cutters 12 before it enters the winding station where driven support rollers 11, 13 perform the winding operation; when a reel 15 has been almost completed the spiders 1, 2 index forward one step, a transverse cutter 14 being operated to sever the web before position 4b, (3b) is reached. From position 4b, (3b) the shaft 8 with the completed reel 15 is moved to position 4c, (3c); during this movement the cullis block 5 retracts radially of the spider 2 under the control of cam 7 thus freeing one end of the shaft 8 so that the reel 15 can be removed. The spiders 1, 2 are then indexed to bring the shaft 8 into position 4d, (3d), block 5 remaining in the retracted position during this movement, so that a fresh core 17 can be placed on the shaft. Thus the winding cycle can continue without interrupting the supply of web to the machine.

Abstract: 1,005,824. Photo-electric-spectrometers. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Oct. 18,1963 [Oct. 22, 1962], No. 39960/62. Heading G1A. [Also in Division H4]. In a spectrometer employing a diffraction grating 11 Fig.1as the dispersing element wander - ing of the image due for example to scintillation is allowed for by utilizing a wide entrance slit 13 and high resolution is maintained by deriving from an undiffracted image a signal varying with lateral movement of the apparent source of light. In one embodiment the undiffracted image falls on a photo-cathode 16 in a tube incorporating an electron slit 18, an electron-sensitive surface 19 and a deflexion coil 17; a similar tube is placed to receive the first-order diffracted ray 25. The signal from surface 19 passes to a servo-mechanism 27 which supplies current to deflexion coils 17 and 22, thereby keeping the ray falling on surface 24 centred and permitting the use of narrow slits 18, 23 for high resolution. By applying an additional independently controlled signal from a generator 28 to coil 22 a scan according to wavelength can be effected and this is recorded by unit 29 which also receives the signal detected by circuit 26. A constructional arrangement is given, Fig. 2 (not shown). A block schematic circuit for the system of Fig. 1 is shown in Fig. 3: an oscillator 35 supplies coil 17 and a phase-sensitive rectifier 36. The light signal produced on surface 19 excites a photo-multiplier 37 the output from which feeds rectifier 36 which applies the position-correction voltage via D.C. amplifiers 39, 41 to coils 17, 22. In an alternative arrangement, slits 18, 23 are moved mechanically; in Fig. 4 slit 18 is in a member 45 mounted by spring strips 46 which also carry a coil 47 in the gap between magnetic poles 48. An analogous circuit arrangement to that of Fig. 3 is employed, Fig. 5 (not shown). Electrostatic displacement of the slits may be used.

Title: Surface-active sulphates of alkyl ether alcohols and a process for their preparation
IPC: C07C305/10
Filed: 1962-10-29
Abstract: The invention comprises surface active sulphates of alkyl ether alcohols of the formula R1R2R3C.O.CH2CH2OH in which R1 and R2 are alkyl groups, R3 is hydrogen or an alkyl group, and R1, R2 and R3 together contain at least 7, and preferably not more than 19, C atoms, and alkali metal, ammonium or amine salts thereof.  R1 preferably contains 10-14 C atoms, R2 is preferably -CH3 and R3, H or CH3. The ether-alcohol may be made by (a) the reaction of olefins with ethylene glycol, (b) the reaction of olefins withethylene halohydrins, followed by hydrolysis of the halogen-containing products, or (c) the reaction of secondary or tertiary alcohols with ethylene oxide. Reactions (a) and (b) require acid catalysts, preferably BF3 or H2SO4, and temperatures of 50-200 DEG C., and a polar solvent, preferably nitromethane, is desirable for (a). Efficiency is improved by the addition to BF3 of 0.3-1.1 moles of water, and a hydrocarbon liquid, e.g. pentane, may be used to extract the reaction mixture. The sulphation is carried out using known agents (listed), preferably a slight excess of chlorosulphonic acid at 0-10 DEG C. Examples I-IV describe the preparation of 1-methyl-undecyl ethylene glycol ether from dodecene-1 and ethylene glycol in nitromethane, using a BF3-water catalyst. Examples V and VI describe the reaction of C13-15 olefins, and of dodecene-1, with 2-chloroethanol, using BF3-water and H2SO4 catalysts respectively, and the hydrolysis of the former product directly to the ether alcohol, using NaOH, and of the latter via the acetate, formed by reaction with potassium acetate, followed by saponification to the ether alcohol. The products are all sulphated with chlorosulphonic acid.

Abstract: 1,127,560. Differential pressure indicator. FRAM CORP. Sept. 7, 1967 [Sept. 9, 1966], No. 40986/67. Heading G1L. A differential pressure indicator in which an indicator 20 is projected outwardly of the housing 10 when a predetermined pressure difference is sensed and in which mechanism is provided so that temporary pressure surges do not actuate the indicator. The indicator 20 is pressed outwardly by spring 24 and is latched in retracted position by a stop fixed on rotatable shaft 50. The two pressures whose difference is being sensed are applied, respectively, to opposite sides of a spring-biased piston 88. A cam 94 on one end of the piston, through follower pin 74, rotates shaft 50 to release indicator 20 when the piston is caused to move in one direction by a pressure differential exceeding a predetermined amount. To prevent the indicator from being actuated by pressure surges a spring pressed valve is positioned in the inlet to chamber 98. If a sudden pressure increase occurs in the inlet line, the valve closes, sealing chamber 98 from the high pressure source. A leakage path is provided between the interior of chamber 98 and the source of high pressure through the looseness of mating threads 80 and 82. Thus if the pressure increase is more than temporary, the pressure in chamber 98 equalizes with the pressure of the source after about a 3-5 second delay, thereby permitting valve 112 to open and the indicator 20 to be actuated. A temperature sensing element is provided to lock the indicator 20 in retracted position until a predetermined temperature is exceeded.
