Patent GB-1413646-A (GB)
Title: Model railway coupler systems adapted for either mechanical or magnetic uncoupling
IPC: A63H19/18
Filed: 1974-03-14
Abstract: 1413646 Model railway coupler systems C K EDWARDS and L D EDWARDS 14 March 1974 [2 April 1973] 11522/74 Heading A6S Model railway cars are coupled by a device comprising two complementary interlocking C- shaped knuckles 14, 16, each being normally held by gravity in a horizontal position but being free to rock upwards so as to clear the other during coupling or uncoupling. Attached to each knuckle is a permanent magnet 36 having elongate upper and lower poles whereby it may be rocked upwards through magnetic repulsion when exposed to an electromagnetic field at an uncoupling station 18 comprising a coil 22 round on electromagnet with elongate poles 24. The uncoupler 18 is set beneath the rails with one pole 24 lying alongside one of the rails 25 so that the permanent magnet on one of the knuckles is repelled when the car passes over the uncoupler, and the other is effectively uninfluenced thereby. This method of uncoupling may be in addition to the standard uncoupling device whereby the up ward rocking of the knuckle is brought about by co-operation of a downwardly extending finger 40 with a lifting ramp 42. The tail 68 of the coupling knuckle which is triangular in section is contained within a rectangular cavity 60 in the truck 48 by a clip 78. The limit of vertical upward rocking of the knuckle is thus brought about by abutment of the face 84 of the tail 68 upon the face of the retaining clip 78.

Title: Improvements in or relating to the purification of nickel and cobalt electroplating b
IPC: C25D21/18
Filed: 1962-03-27
Abstract: Metal impurities in acidic nickel and cobalt solutions e.g electroplating solutions, are removed by adding sufficient barium or strontium oxides, hydroxides or carbonates to the solutions in order to raise the pH above 5 and filtering off the precipitated impurities.  When chloride solutions are to be purified a slight excess of soluble sulphate may be added after the pH raising stage to precipitate any barium or strontium that may be in solution. In the example, portions of a standard Watts solution containing about 300 g/l of nickel sulphate about 60 g/l of nickel chloride and 40 g/l of boric acid were oxidized with hydrogen peroxide and the metal impurities precipitated therefrom by the addition of barium and strontium hydroxides and carbonates.  In all cases the final pH was 5.2 and the temperature was either 55 DEG  or 65 DEG  C.

Title: Improvements in and relating to barrelling machines
Inventor: SMITH-GORMAN ROBERT JACK
IPC: B24B31/02
Filed: 1958-04-14
Abstract: 841,447. Barrelling. ROLLS-ROYCE Ltd. Feb. 5, 1959 [April 14, 1958], No. 11786/58. Class 60. A barrelling machine comprises a plurality of barrels 15, means for rotating them simultaneously, a plurality of barrel-stopping mechanisms, one for each barrel, so that a selected barrel may be stopped whilst permitting rotation of the remainder, and a timing device for controlling each barrel-stopping mechanism so that rotation ceases at the end of the pre-set period of the associated timing device. The barrels 15 are friction-driven by rollers 3 mounted on parallel shafts 1, 2 which are chain-driven by a motor 8 through a variable speed unit. Each barrel is carried in a cradle 16, pivotally mounted on a shaft 17 which carries an idler roller 24 between the end-plate 18, further idler rollers 21, 22, are carried between the ends of the arms of the plates 18. The upper arms of each cradle are joined by an abutment portion 25 which, when the barrel is in driving engagement with the roller 3; bears against the frame of the machine. A spring 27 urges the cradle towards the disengaged position shown at A, Fig. 2, but each cradle is normally held by a solenoidreleasable catch in the barrel-driving position, the catch engaging the spindle 19 of the roller 21 in a gap formed by dividing that roller ; when the drive is disengaged by releasing the catch the projecting ends of the spindle 19 engage the machine frame to limit the outward movement of the cradle to the unloading position. The solenoids are operated by timeswitch 45 mounted on a front panel 42, the switches being controlled by buttons, each switch being independently set for the running period of its associated barrel. A sink unit 50, below which is a shoot and bin 56, is centrally disposed at the front of the machine for sieving the barrelling chips from the workpieces, together with a hose 47 and accommodation for screens 53 of different mesh. The barrels. Fig. 6 and 8, may be polyethylene mouldings, each with four shallow internal ribs 39 extending across the inner wall, a cover 37 of similar material being sprung into a rim 35, or a cover of rigid material with locking means may be used. The ribs 39 are stepped on one side to collect the chips, causing them to follow the path indicated in dotted lines in Fig. 8, the direction of rotation being clockwise. To ensure that barrels are correctly loaded into the machine the idler rollers are offset on their spindles to accommodate a wide peripheral rib 32, Fig. 6, moulded on the cylindrical outer wall of each barrel. A liquid medium may be used for the barrelling process.
Patent GB-935802-A (GB)
Title: Production of alcohols
IPC: C07F5/06
Filed: 1962-03-28
Abstract: Alcohols are produced by oxidising a feedmixture of alpha-olefins and trialkyl aluminium with an oxygen-containing gas to produce partially oxidised aluminium alkyl in which up to 70% of the alkyl substituents are converted to alkoxy groups, separating, by stripping, the a -olefin from the partially oxidised aluminium alkyl, and oxidising with an oxygen-containing gas the separated partially-oxidised aluminium alkyl to produce trialkoxy-aluminium which is then hydrolysed to the corresponding alcohol.  The process is suitable for treating the mixture of a -olefins and trialkyl aluminium obtained by treating aluminium triethyl with ethylene.  The solvent used for this reaction may be retained in the mixture of alpha-olefins and trialkyl aluminium used as starting material and is stripped off with the a -olefine after the first oxidation step.  In general the alkyl groups of the trialkyl aluminium each contain 4-30 carbon atoms.

IPC: C08L91/08
Filed: 1961-03-30
Abstract: A composition suitable for use in candles consists by weight of (a) 45-55%, preferably 50%, of a paraffin wax of M.P. 125 DEG -132 DEG F., penetration (A.S.T.M.) at 100 DEG F. of 80-120, and viscosity at 210 DEG F. of 38-40 S.U.S., (b) 32-42%, preferably 37%, of a paraffin wax of M.P. 130 DEG -136 DEG F., penetration at 100 DEG F. of 30-50, and viscosity at 210 DEG F. of 36-39 S.U.S., and (c) 10-16%, preferably 13%, of a paraffin wax of M.P. 149 DEG -155 DEG F., penetration at 130 DEG F. of 35-65, and viscosity at 210 DEG F. of 42-46 S.U.S.  Candles made from this composition generally also contain 3-30% stearic acid by volume of the total composition.  Wax component (a) may be obtained either (1) by distilling a slack wax obtained from lubricating oil to obtain a fraction boiling at 390 DEG -565 DEG F. at 2 mm., dissolving the fraction in a solvent, cooling to 75 DEG -83 DEG F., filtering off and discarding the precipitate, cooling the filtrate to 25 DEG -33 DEG F., and filtering off the required crystals which have separated, or (2) by combining the crystals obtained by dissolving the slack wax distillate boiling at 390 DEG -475 DEG F. at 2 mm. in a solvent and cooling to 25 DEG -32 DEG F. with those obtained by dissolving the slack wax distillate boiling at 450 DEG -565 DEG F. at 2 mm. in a solvent, cooling to 72 DEG -82 DEG F., filtering and then cooling the filtrate to 25 DEG -33 DEG F., the crystals obtained from the distillate fraction boiling at 390 DEG -475 DEG F. at 2mm. generally forming 69-75% of the mixture. Component (b) may be obtained by distilling slack wax from the dewaxing of lubricating oil or a topped, high wax-content crude petroleum to recover a fraction boiling at 390 DEG -475 DEG F. at 2 mm., dissolving the fraction in a solvent and recovering the crystals which separate at 32 DEG -37 DEG F. Component (c) may be obtained by distilling slack wax from the dewaxing of lubricating oil or a topped, high wax-content crude petroleum to recover a fraction boiling at 450 DEG -565 DEG F. at 2 mm., dissolving the fraction in solvent and recovering the crystals which separate at 77 DEG -83 DEG F.  The solvent used in the crystallization of the wax fractions is usually a mixture of methyl ethyl ketone and benzene, but if required toluene may be substituted for a part of the benzene.

Title: Improvements in devices for measuring the temperature of gaseous fluids and in particular of flames
IPC: G01J5/00
Filed: 1955-04-25
Abstract: 805,123. Measuring temperature. OFFICE NATIONAL D'ETUDES ET DE RECHERCHES AERONAUTIQUES O.N.E.R.A. April 25, 1955 [April 27, 1954], No. 11892/55. Class 40 (3). Apparatus for measuring the temperature of a gaseous fluid (e.g. a flame) comprises an optical system for imaging a light source on the flame, and a shutter disposed upstream of the flame so as to cut off a part of the light beam and an optical system disposed downstream of the flame for splitting the beam coming therefrom so that the split beams fall on separate detectors (e.g. photo-electric cells) one split beam emanating from the flame and corresponding to the cut-off part of the beam from the sources and the other split beam coming directly from the source and passing through the flame. As shown, a light source 1 is imaged by lens 3 at 1a where an adjustable shutter is placed so as to cut off one half of the beam. Lens 4 forms an image of 1a at 1b where the flame of which the temperature is to be measured is disposed so that the light from the source passes through only one half of the flame. Light from the flame now falls on the entrance slit of a spectrometer 9 and then on to a mirror 10 so disposed as to direct that part of the beam which emanates only from the flame at 1b on to a photo-cell R1 while that part of the beam from source 1 which has not been blocked at 1a passes to a photo-cell R2. In this way, the intensities of the split beams can be measured and the flame temperature deduced therefrom. By means of the spectrometer and of an adjustable slit between the latter and mirror 10, the temperature can be determined for different wavelengths. Specification 711,924 is referred to.

Abstract: 1,170,657. Distillation apparatus of the vapour-compression type. G. MASCARINI. 15 March, 1967 [24 March, 1966], No. 12083/ 67. Heading BIB. In a distillation apparatus of the vapourcompression type comprising a unitary boiler/ condenser 10 connected by vapour-conduits 19, 20 to a compressor 16 and to a compressor by-pass conduit 23 and valve 24, the boiler being provided with auxiliary electric heater elements 13, 14, the distillate Rows from the condenser into a tank 11 which is provided with an outlet 22 and with sensors 28, 29 for sensing maximum and minimum levels of condensate in the tank, and these sensors, together with temperature and pressure sensors and electric control devices 30, 31 automatically control the starting-up, the running, and the shutting-down of the apparatus. Pressure-responsive elements 4, 5, 6, disposed e.g. in the vapour-dome, boiler and conduit 20 respectively, are connected to device 30. Temperature-responsive elements 1, 2, 3 disposed in the boiler, compressor and one of the conduits 19, 20, respectively, provide electric signals to programmer 31 comprising a series of cams C rotating on shaft 40. Device 30 starts up the apparatus when a signal is received from sensor 29 in tank 11. Heaters 13, 14 are put in operation by programmer 31; compressor motor 15 is inoperative, bypass valve 24 is in the closed position, and the drain valve 26 of the compressor is open. When boiler 10 has reached suitable temperature, elements 1, 2, 3 send a signal to motor 42 to commence rotation of shaft 40, whereby valve 24 is opened, and the compressor is put in operation. Valve 24 is then slowly closed, and the drain valve 27 for non-distilled liquid is opened. During the normal working phase of the apparatus, heaters 13, 14 are switched to maintain optimum conditions in the boiler. When the distillate reaches the level of sensor 28 in tank 11, device 30 stops the operation of the apparatus. The apparatus is also shut down when device 30 receives a signal from elements 4, 5, 6 in the event of lack of feed liquid to the boiler or faulty pressure conditions therein.
