Abstract: 414,655. Mixing-machines. HARRISON, N., 18, Killowen Street, Low Fell, Co. Durham, and FIELD, H. S., Grey Walls, Harlow, Essex. Feb. 4, 1933, No. 3489. [Class 86.] The drum of a concrete &c. mixer is rotated by rubber-tyred rollers on which it rests, means being provided for raising the drum for stopping its movement ; for rotating the drum by hand in an emergency, ratchet mechanism is provided on one of the supporting rollers. The drum 1 is mounted on front and rear pairs of rollers 3, 2, the former being driven from an engine 5. The drum can be raised by means of a handoperated toggle 7 carrying rollers 8 which lift the drum out of contact with the driving rollers ; the toggle may be replaced by lever mechanism. One of the rollers 2, normally loose on its shaft, can be secured thereto by a set screw &c. and the shaft rotated by means of a hand-lever 17 having a hub fitting over the shaft and fitted with a spring pawl, the end of the shaft being formed as a ratchet. The drum may be driven by rollers on the same side of the machine, being raised out of contact therewith by a pair of rollers on a jack. The supporting rollers may be adjustably spaced to carry drums of varying size.

Abstract: 1,189,096. Reforming hydrocarbons. E. J. HOFFMAN. 22 Jan., 1969, No. 3504/69. Heading C5E. Carbonaceous material (coal, peat, lignite, gilsonite, oil shale, oil sand, tar sand or coke or petroleum fractions) is converted directly to hydrocarbons by reaction with steam (and optionally O 2 ) in the presence of a multicomponent catalyst comprising at least one compound of an alkali or of an alkaline earth metal, and at least one compound of an element of Group VIII of the Periodic Table. Figure 1 is self-explanatory, but the fluidized bed reactor may be replaced by a moving bed reactor, or by one or more fixed bed reactors in parallel. Reaction conditions are temperatures in the range 800‹ to 1200‹ F., and pressures up to 500 p.s.i. Oxides and carbonates are preferred for the first catalyst component, and compounds of Ni, CO, and Fe for the second, especially Fe oxides. The reaction may be performed with the carbonaceous formation in situ, oxygen and superheated steam with dissolved or entrained catalyst being supplied to the formation, which may be low API gravity petroleum. In a specific embodiment described with reference to Figure 1, the catalyst comprises 10 wt. % Na carbonate and 90 wt. % impure iron ore, including iron carbides. A molar ratio of 1-5 (steam to carbon) and a space velocity of 400 per hour are maintained.

Title: Process for the isolation of pentaerythrite from its solutions
IPC: C07C31/24
Filed: 1941-03-18
Abstract: Pentaerythrite is purified by causing an aqueous solution of the compound to crystallize at a temperature higher than 40 DEG  C. and separating the crystals from their mother liquor at a temperature above 40 DEG  C.  Under these conditions, impurities such as dipentaerythrite, remain dissolved in the mother liquor.  The crystallization may be effected by evaporation of the aqueous solution, with or without subsequent cooling.  In an example, 100 parts of a 10 per cent solution were concentrated in a vacuum at 85 DEG  C. until 84 parts of water were distilled off.  The crystals formed were separated from the mother liquor by filtration with suction at this same temperature, washed with a small quantity of a saturated aqueous solution of pentaerythrite and dried.  The yield was 90 per cent.  In another example, the evaporation is carried out at 104 DEG  C. under ordinary pressure and is followed by cooling to 90 DEG  C. with stirring.  The crystals are then separated at 90 DEG C.  Specification 440,691, [Group IV], is referred to.ALSO:Pentaerythrite is purified by causing an aqueous solution of the compound to crystallise at a temperature higher than 40 DEG  C. and separating the crystals from their mother liquor at a temperature above 40 DEG  C.

Title: Removing hydrogen sulphide from gases
Inventor: MILLS JOHN ERIC
IPC: C10K1/16
Filed: 1956-02-10
Abstract: 827,153. Purifying gases. GAS COUNCIL. Jan. 31, 1957 [Feb. 10, 1956], No. 4312/56. Class 55 (2). In a process for removing hydrogen sulphide from gases, e.g. coal gas, which consists in alternately washing the gases with a liquid comprising a solution or suspension of an organic compound which will yield a readily oxidizable reduction product on contact with hydrogen sulphide, and bringing the liquid containing the reduction product into contact with air or oxygen to oxidize the reduction product back to the original compound, the process is so conducted that during absorption of hydrogen sulphide there is at all times an excess of the organic compound in its non-reduced form while during the oxidation with air or oxygen there is at all times an excess of the organic compound in its reduced form. Suitable organic compounds are certain dyes, e.g. methylene blue, used in solution in a solvent, e.g. aniline, in conjunction with a catalyst, e.g. pyridine or quinoline. In an example the oxidized solution passing into the absorber contains 1.5% methylene blue in the non-reduced form and 0.5% in the reduced form and the solution leaving the absorber and passing to the oxidizer contains 1.5% methylene blue in the reduced form and 0.5% in the non-reduced form. Specifications 827,151, 827,152, [Group III], and 827,154 are referred to.

Title: Improvements in or relating to Light Beam Deflector Systems
Inventor: MANSELL JOHN REVERE
IPC: G02B27/28
Filed: 1967-01-30
Abstract: 1,168,161. Light deflectors. MULLARD Ltd. 30 Nov., 1967 [30 Jan., 1967], No. 4420/67. Heading H4F. [Also in Division G2] A digital light beam deflector system comprises two birefringent crystals X1 and X2, Fig. 1, of the same material and arranged as shown, so that depending on the plane of polarization of an input (achromatic) light beam P or P<SP>1</SP> it emerges undeflected at b2 or deflected at b1 due to total internal deflection (T.I.R.) at the interface B and a further T.I.R. at face C. The deflector of Fig. 1 comprises two negative uniaxial crystals of calcite with their optic axes OA1 and OA2 orientated orthogonally. For light beam b0 incident normally on face A and travelling through crystal X1 parallel to its optic OA1, the refractive index is equal to the ordinary refractive index Á 0  irrespective of the direction of polarization. A beam P polarized in the plane of the Figure experiences no change in refractive index at interface B and passes through the second crystal X2 undeflected. A beam polarized at right angles to the plane of the Figure P<SP>1</SP>, experiences a change in refractive index at interface B since the refractive index in the second crystal is that of the extraordinary ray Áe. This beam is totally internally reflected at B if the angle of incidence (90-#) is greater than the critical angle α c  given by sin α c  = Áe/Á 0  (with Áe<Á 0 ). The final displacement of the beam depends on the separation of the two inclined faces of crystal X1. The two crystals are in optical contact or cemented together with an adhesive having a refractive index equal or close to Á 0 (the critical reflection taking place at the interface between the cement and crystal X2). In operation the device is preceded by an electro-optic switch and a plurality are arranged in series, Fig. 4 (not shown). The crystals may be positive uniaxial crystals Áe>Á 0  in which case the directions of the optic axes are changed by 90 degrees, Fig. 3B (not shown). In a third embodiment, Fig. 3C (not shown), the crystals are biaxial crystals arranged so that an incident light beam polarized in one direction experiences a refractive index Áb in both crystals and passes through undeflected, but light polarized at right angles experiences a change from Ác to Áa at the interface (Áa<Áb<Ác) and if the angle of incidence on the interface is greater than the critical angle given by sin αc = Áa¸ Ác then the light is totally internally reflected. The output face of crystal X1 may be normal to its input face, in which case a separate external mirror parallel to the interface is used to re-direct the reflected beam into a displaced path parallel to the input beam.
