Patent GB-738000-A (GB)
Title: Improved particulate detergent compositions
Filed: 1952-03-11
Abstract: A solid particulate substantially non-caking detergent composition contains (1) 10-95 per cent by weight of sodium monoalkyl benzene sulphonates having 9-18 carbon atoms in the alkyl chain, and (2) 0.5-10 per cent by weight of sodium benzene or a sodium toluene monosulphonate, the remainder, if any, being essentially inorganic sodium salt builders.  The composition is obtained by drying an aqueous slurry of an intimate mixture of the components of the composition.  The components are preferably mixed by dissolving or dispersing benzene sulphonic acid or p  toluene sulphonic acids or their sodium salts in the caustic soda solution to be used for neutralizing the mixture of alkyl benzene sulphonic acid and excess of sulphuric acid formed by the sulphonation of the alkyl benzene.  A second method consists in adding benzene sulphonic acid or the toluene sulphonic acids to the sulphonation reaction mixture of alkyl benzene sulphonic acid and unreacted sulphuric acid, whereupon the whole is neutralized. A third method consists in adding benzene sulphonic acid or the toluene sulphonic acids to the mixture of C9-C18 alkyl benzenes before sulphonation and, after sulphonation, neutralizing the reaction mixture.  A fourth method consists in sulphonating a mixture of benzene or toluene with C9-C18 alkyl benzenes and neutralizing the reaction mixture.  Comparative experimental results are given in respect of (1) a number of compositions containing 40 per cent by weight of C12-C15 sodium polypropylene benzene sulphonate and 0.6-10 per cent of sodium benzene or toluene sulphonate, the balance being sodium sulphate, and (2) a similar series of compositions containing 42-55 per cent by weight of sodium tripolyphosphate as well as sodium sulphate.  U.S.A. Specification 2,477,383 is referred to.

Title: Improvements in or relating to process for removing wax and other impurities from oil
IPC: C10G73/24
Filed: 1950-03-16
Abstract: <PICT:0701312/III/1> Hydrocarbon oil is dewaxed and decolorized by passing the oil over a solid particulate mass of urea or thiourea and an active solid adsorptive material in the presence of a polar solvent.  Waxy constituents of the oil form solid adducts with the urea or thiourea.  The adsorptive material may be synthetic or naturally occurring, such as silica gel, Fuller's earth or alumina. Polar solvents referred to are water or alcohols, ketones or esters. The solid particulate contacting agents may be employed in a stationary bed or as a slurry with the oil.  Referring to Fig. 1, filter vessel 2 is filled with a mixture of adsorbent and urea from conveyers 40 and 39 respectively, and this filter bed is then saturated with methyl alcohol from pipe 42.  Mineral lubricating oil is introduced into vessel 2 by pipes 1 or 1a and passes through the filter bed.  Treated oil is discharged through pipe 3 or 3a into tower 5 wherein any solvent or urea is removed by solution in a solvent, for example water, introduced via pipe 6. The oil then passes via pipe 7 either to vacuum dehydrator 11 or to blotter press 12.  Finished oil leaves the system through pipe 13.  In a modification, the dewaxed oil is conducted through pipes 3 or 3a, 4 and 61 direct to vessel 11, where steam may be introduced through line 17 to remove solvent through pipe 15; the oil is then either led through pipes 10 and 16 to blotter press 12 or removed directly from the system by pipes 62 and 13.  Methods for the regeneration of the spent filter bed and recovery of the wax are also described.

Title: Apparatus for Indicating Changes in the Course of a Ship, Airship, Aeroplane or the like, also applicable for Automatic Steering.
Inventor: HENDERSON JAMES BLACKLOCK
IPC: G01C19/38
Filed: 1916-05-11
Abstract: 125,096. Henderson, J. B. May 11, 1916. Gyrostatic-precession speed indicators. - Relates to improvements upon apparatus of the kind referred to in Specification 7285/10 for indicating the rate of angular movements, e.g. the roll of a ship, in order that rate of change of course, and total change of course since last setting may be determined and the instrument rendered applicable to the automatic control of steering-mechanism. A small gyroscope is contained within a casing 1 mounted on an horizontal trunnion axis 2 in a frame 3 rigidly carried by the ship or aircraft with the rotor axis horizontal and fore-andaft. Within a casing 4 upon the axis are braking-disks 5 rotating in a viscous fluid, the casing being restrained by springs 6 attached to arms 7 upon the frame, and the relative movement of the parts indicated by a pointer and scale 8, 9 with pin-and-fork actuating-means. Movement of the rotor casing relatively to the brake casing is shown by a pointer and scale 13, 14. If, when the rotor is spinning, the pointers are set to zero while the ship ie on a prescribed course, the reading on the former scale will be a measure of the angular rate of change of course, and on the latter scale of the total deviation from the prescribed course. In an alternative design, the spring-controlled parts have less inertia, and the spring member is interposed between the horizontal axle and the brake disks, so that the brake casing may be incorporated in the base of the instrument. When employed for the control of steering, a crank 23 upon the end of the trunnion axle 2 transmits to the tiller head, through a servo-motor, a movement compounded of those due to the rate of change of bearing and the total change respectively.

Abstract: 980,308. Making-pipes. BRISTOL AEROPLANE PLASTICS Ltd. March 1, 1961 [March 3, 1960], No. 7578/60. Heading F2P. A resin-bonded fibre pipe has for internal or external protection a facing layer of resinbonded fibre material so that the layer is more resistant to abrasion or chemical attack than a layer of the basic fibre forming the body of the pipe, and a second layer lying between the facing layer and the body of the pipe and consisting of a cloth of a resin-bonded fibre stronger than that in the facing layer. The basic fibre is preferable glass incorporated as a winding, or cotton thread, or strong polyester fibre. The fibre of the second layer is preferably glass and that of the facing layer acrylic, or nylon, or a polyester, which fibre runs in two or more intersecting directions. The cloth of the second layer is formed by weaving, knitting or felting (as may be the basic layer), but is preferably in the form of a woven tape. As shown, resin impregnated tapes 29, 30 stored in cassettes 21, 22, mounted on a rotatable winding head 18, are helically wound on a mandrel 15, which rotates in the same direction as the winding head and moves axially. The widths of the tapes 29, 30 are substantially equal to a multiple of the pitch of the turns, say three times and twice, so that there are around the bore of the pipe two layers of the facing tape, surrounded in turn by a layer of the second tape, a further layer of the facing tape and a further layer of the second tape. Glass fibre 31 from the cassette 23 is wound over the tapes, being impregnated on its way to the mandrel. Two layers are wound over the glass fibre body for protection.

Title: Automatic machine for manufacturing blown glass articles
IPC: C03B9/20
Filed: 1924-03-25
Abstract: 213,576. Soc. Anon. d'Etudes et de Constructions d'Appareils MÚcaniques pour la Verrerie. March 30, 1923, [Convention date]. Blowing; gathering.-An automatic machine for forming glassware has a suction gathering device which comprises means for moving the parison mould into the working-hole of a tank furnace and for dipping it into the metal, a movable gate being used to cover the hole during gathering-operations in order to shield the machine from heat. The machine is mounted on a wheeled base 1 to enable it to be brought up to the tank furnace, a casing 2, mounted on the base, enclosing the driving shaft and the cams that control the various movements of the machine. Only a single set of moulds is used, the finishing moulds 4 being placed at a lower level than the parison mould 20, and the ring mould 36 reciprocates vertically from one mould to the other. The parison mould 20 consists of two halves carried by arms 24 which are pivoted to the underside of a carriage 19. This carriage can slide on bars 15 which are pivoted at 17 near one end, and at the other end are connected to a link 18. The carriage is moved forwards to project the parison mould into the working-hole, as shown in dotted lines, and the link 18 then raises the fare end of the bars 15 and thus dips the lower end of the mould into the metal. After a charge has been sucked into the mould, the action is reversed and a knife 58 is projected forwards to cut off the thread of metal from the bottom of the mould. The suction to fill the mould is applied through a cap 49, which fits on to the ring mould and is connected by a tube 50 with a vacuum pump. After the withdrawal of the filled mould from the tank, a gate 54 of refractory material, which was raised through the agency of links 56, 57, to admit the mould, is lowered, and the machine is thus shielded from heat radiated from the working hole. The mould is now opened by a slide 27, which moves on bars attached to the underside of the slide 19 and is operated by a lever 30 from a cam. The ring mould 36 has been engaged by pins 38 projecting from hanging rods 40 pivoted on a slide 43. This slide is now lowered and carries the ring mould with the suspended parison down to the open finishing mould 4. This mould is closed and the ring mould is opened and raised again, and a blowhead 61 is moved on to the finishing mould. The bottle is now blown and at the same time the parison mould is moved into the furnace to gather a new charge of metal. Finally, the mould 4 is opened and the finished article is tilted by the blowhead 61 on to a shoot 63.
