Title: Accelerometer.
IPC: G01C19/38
Filed: 1967-06-20
Abstract: 1,150,134. Measuring acceleration electrically. NORTHROP CORP. June 20, 1967 [June 28, 1966], No.28361/67. Heading G1N. An inertial mass 40, Fig. 1 is fixed by means of stub shafts 41, 42 and Piezo electric elements 55 to a cylinder 30 with which it rotates about an axis 65 inside a housing 11, the Piezo electric elements being so inter-connected that they produce a net output in response only to acceleration transverse to the axis 65. Rotation of the cylinder 30 in its gas bearings is produced by coils 24, and the assembly forms part of a gyro. Each stub axle 41, 42 is supported by four perpendicularly arranged Piezo elements (55, Fig.2, not shown) the cone-shaped ends of which are fixed to rings (51 and 54) on the shafts and cylinder respectively, allowing some relative movement of mass 40 and cylinder 30 in the axial direction and rotational direction but not in the radial direction. The elements are connected in a circuit Fig. 3 (not shown) in which all signals produced by axial or rotational movement cancel, but those produced by radial pressure are additive. Alternatively, the outputs of all the elements may be monitored individually; or they may be combined in two output leads, one lead for all the elements in one axial plane, and one for the rest, to provide a resultant signal at twice the spin velocity the components of the resultant signal being related to orthogonal axes by timing signals generated by rotation of the mass 40. In a refinement Fig.4 (not shown), the mass (85) may rotate relatively to the cylinder.

Patent GB-878855-A (GB)
Title: Apparatus for improving diesel fuel ignition quality
IPC: C10L1/24
Filed: 1959-08-20
Abstract: Additives for diesel fuels include the thionitrates and thionitrites, some chloro nitro compounds such as trichloronitro methane, chlorine, amyl and butyl nitrates, amyl nitrite and the alkyl nitro carbamates particularly N-methyl N-nitro, methyl carbamates.  In addition normally unusable organic sulphur compounds, particularly amyl thionitrite, tertiary butyl thionitrite and ethyl thionitrite, may be used with the above apparatus.  These provide a substantial cetance boost for low cetane diesel fuels and are used for starting only, in very small amounts e.g. 1 to 3% by weight.  As a solvent for incorporating such sulphur compounds in the fuel liquid spirits may be used e.g. petroleum naphthas, petroleum benzine and ether which is itself an excellent cetane booster.  Specification 606,212 is referred to.

A flyer of the type including two U-shaped clamping members arranged to receive a bush which locates on the flyer spindle, there being a flyer arm of spring steel secured to said clamping members and projecting substantially perpendicularly to the axis of the bush, is characterized in that the flyer arm at a point close to the clamping members is provided with at least one loop which serves to take up the stresses in the arm caused by oscillation thereof. The embodiment illustrated comprises two U-shaped clamping members 10 and 11 which are secured together by rivets 13 and serve to grip and locate a bush 14 of a mouldable plastic such as "nylon" which locates on a textile spindle. The clamping members are grooved at 17, 18, and a flyer arm 19 of spring steel wire extends into the groove and a loop on this arm encircles the bush 14 so as to retain the bush in the clamping members 10 and 11. The arm 19 has the usual thread guide eye 21 and a second loop 22 provided at a point close to the clamping members 10 and 11. Other embodiments are provided with two loops in the flyer arm in addition to the usual eye at the end.

Filed: 1974-06-28
Abstract: 1443603 Hydrostatic transmission control; lirikwork SPERRY RAND CORP 28 June 1974 [2 July 1973] 28761/74 Headings F2W and F2K In a hydrostatic transmission control linkage for a trench digging vehicle wherein a single lever 42 is moved forwards and backwards to control the speed and direction of the vehicle and is moved side-to-side to steer the vehicle, a lock 106 is provided to secure the control lever 42 in a predetermined steering position whilst permitting speed control by the lever 42. The lever 42 is fast with a ratio control shaft 48 which is connected by arms 66, 67 and cables 70, 71 to adjusting elements 78, 76 controlling flow from a pump 24 to hydrostatic motors 20, 22 driving wheels 16 on opposite sides of the vehicle. Rotation of the shaft 48 effects equal changes in the transmission ratios whilst bodily pivoting the shaft 48 about its centre effects equal and opposite transmission ratio changes to steer the vehicle. One end of the shaft 48 is connected by a ball joint 82 to a linkage 84 which is pivotally connected to the lock mechanism 106. During steering movement of the lever 42 the linkage 84 and lock mechanism 106 perform accompanying corresponding movement. When it is desired to lock the steering mechanism a knob 106 is tightened to prevent further movement of the linkage 84 and thus further pivoting movement of the shaft 48. Thereafter side-to-side movement of the lever 42 is prevented whilst forward and reverse movement of the lever 42 is permitted by the ball-and-socket joint 82. When the lock mechanism 106 is released and the lever 42 is released a spring 112 moves the lever 42 to a central neutral position.

Title: Improvements in and relating to sulphonates
IPC: C07C303/44
Filed: 1963-07-23
Abstract: "Olefin sulphonates" are prepared by reacting olefins having terminal double bonds and 8-22 carbon atoms with 1 to 1.7 moles per mole of olefin of gaseous SO3 in an inert diluent gas, at 20-100 DEG  C., and bleaching the product, before, during, or after hydrolysis, with hydrogen peroxide or an alkali metal chlorite or hypochlorite, or materials forming these under the bleaching conditions.  The sulphonating gas may contain 1-20% of SO3.  The hydrolysis may be acid-usually achieved merely by adding water-or alkaline, when alkali metal or alkaline earth metal hydroxides, carbonates or bicarbonates, may be added, or amine bases may be used.  The hydrogen peroxide may amount to 0.5-10% of the sulphonate weight, and other bleaching agents are used in equivalent quantities, the bleaching preferably occurring at 20-100 DEG  C. The preferred bleaching conditions are pH 6-8, and 40-50 DEG  C., using an alkali metal hypochlorite, after an alkaline hydrolysis.

Abstract: 1,254,741. Fluid propelled bodies in pipes. INSTITUT FRANCAIS DU PETROLE DES CARBURANTS ET LUBRIFIANTS. 9 June, 1969 [7 June, 1968], No. 29166/69. Heading F2N. A device, adapted for instance to be pumped through a pipe carrying a boring tool into an oil well, comprises one, or more, annular arrangements of curved bearing-plates 7 which, in operation, are resiliently urged against the wall of the pipe, each annular arrangement consisting of an elastic sleeve 6 having bonded to its outer surface a cylindrical arrangement of metal plates 7 each having, along one axial side, a lug 8 which makes a sealingly tight engagement with a corresponding recess 9 in an adjacent plate. In this manner, when the plates are sprung circumferentially apart and are pressed against the inner surface of a pipe 5, the lugs 8 block the passage of liquid, e.g. oil, from one side of the device to the other, through the spaces between the plates. In a modification, Fig. 3 (not shown),  the plates (7) have extensions (11) with projections (12) which engage, for limited radial movement, in slots (13) between abutments formed by distance-pieces (14) and rings (15) which are located on a core (10) having threaded apertures 4 at its ends for attachment of, e.g., a boring tool. Fluid pressure can be supplied to the interior of the elastic sleeves (6) through openings 16, 17 respectively in the core (10) and the distance pieces (14). In a further modification, Fig. 9 (not shown), two or more rings are placed sideby-side with the gaps between the plates relatively offset circumferentially so that the passages between the plates are also blocked by the plates of the neighbouring rings at each side. In another arrangement the elastic sleeve incorporates springs which are located between radial ribs depending from the plates to urge the latter apart circumferentially. Stops may be provided at the end of the lugs 8 to co-operate with stops on the corresponding recesses. The plates may be alternately provided with two recesses 9 and two lugs 8.
