Title: Improvements relating to methods of producing alumina films
IPC: C25D11/04
Filed: 1967-01-24
Abstract: A method of manufacturing an alumina film comprises the steps of forming a porous alumina frame 5-20 m  thick on one side of an aluminium foil by anodic oxidation, forming an alumina film on the same side of the foil by anodic oxidation of the foil enclosed by said frame such that the film and the frame are integral, and then removing the remaining metallic aluminium with the aid of a reagent which dissolves aluminium but does not appreciably attack the alumina.  The porous alumina frame may be formed using an oxalic acid or sulphuric acid electrolyte and the alumina film, which may be about 0.1 m  thick, may be formed using a 4% aqueous solution of tartaric acid or a 6% aqueous solution of boric acid containing 1.5% sodium borate.  The reagent used to dissolve the metallic aluminium may be a mixture of hydrofluoric and nitric acids or a mixture of chromic and phosphoric acids.  The film may be formed with two concentric annular frames, the outer being later cut away.  A vopour deposited layer, e.g. of PbO may be formed upon the alumina film.

Title: Catalytic reforming
IPC: C10G35/00
Filed: 1941-03-14
Abstract: 549,963. Hydrocarbons. STANDARD OIL DEVELOPMENT CO. March 14, 1941, No. 3494. Convention date, March 28, 1940. [Class 2 (iii)] In the process of subjecting hydrocarbons boiling within the gasoline range to a process of catalytic reforming, the proportion of saturated to unsaturated hydrocarbons in the feed stock is increased as the catalyst becomes less active so as to increase the quantity of hydrogen produced, and thus to enable the reaction to continue without regeneration of the catalyst. Catalytic reforming comprises the heat treatment under pressure of the said hydrocarbons at 800-1100‹F. in the presence of hydrogen and a catalyst, with recycling of the normally gaseous products, the time of treatment being so adjusted in conjunction with the temperature, pressure and partial pressure of the hydrogen that there is no net consumption of hydrogen. The catalysts employed are the oxides and sulphides of metals of groups II, IV, VI and VIII of the Periodic Table, preferably supported upon clays, bauxite, activated alumina, aluminagel, peptized alumina, silica, silica gel, aluminium silicates and silicamagnesia. A plurality of reaction vessels may be used having separate-feed stocks but only one system for recycling the gaseous products containing hydrogen, whereby the hydrogen produced by the treatment of the feed stocks rich in saturated hydrocarbons compensates for the hydrogen consumed in other reaction vessels. A feed stock may also be separated into two fractions, one rich in saturated constituents and the other poor in saturated constituents, and the latter used first. The resulting fuels may be blended with tetraethyl lead, iron carbonyl, isopentane, alkylated isobutane, isopropylether, hydrogenated polymers of isobutylene, and oxidation and gum inhibiting agents.

Abstract: 414,150. Coin-freed liquid-delivery apparatus. ELECTRIC FIRES, Ltd., SMITH, C. H., Heatrae Works, St. George's Street, Norwich, and MILLNER, W., 6, Eccleston Place, London. Feb. 7, 1933, No. 3710. [Class 27.] Coin action, mechanicalconnection.-A liquid delivery tank a, Fig. 1, is filled through a pipe d from a source of supply to a level indicated by a float gauge y, the liquid passing through a plug cock f forming the inlet valve. The tank a is discharged through an outlet valve p. A coin inserted through a slot b enters coincident slots h<1>, k', Fig. 6, in discs h, k loose on and fixed to the stem of the plug cock f. An operating handle g is secured to a boss extending upwardly from the loose disc h. The disc k is formed with a cam on its under surface to actuate the outlet valve, and a fixed slotted guard plate v is disposed between the loose disc h and the cam diso k, the slot in the plate v being of progressively increasing widths w, w1, w2. The inserted coin projects through the portion w to couple the discs together so that the disc k rotates with the handle g and opens the inlet valve. At the same time its cam by acting on a roller r on the valve stem g closes the outlet valve p against its seat pl. The coin enters the slotted portion w<1> and drops further through the plate v, thus preventing the handle g with the discs h, k from being returned to their initial position before a full stroke of the handle is made. The coin ultimately drops through the wide slot w<2>. When the tank is full, the handle g is returned, the disc h driving the disc k by a pawl 2 so that the inlet valve is closed and the outlet valve opened. In a modification, Fig. 13, the inlet pipe d opens into a valve box 6 and both the inlet and outlet valves 5, p are controlled by the cam on the diso 17 engaging rollers 9, r on the valve stems 10, g. The handle operated disc 13 has an elongated coin slot or holder 15 coincident with a slot 16 in the cam disc 17, the coin passing through both slots and resting on a stepped slotted support plate 19. The step on the plate 19 prevents the handle being returned before a full stroke has been made.

Abstract: 468,715. Prepayment mechanism for meters. MEASUREMENT, Ltd., and CLIFFORD, C. F. Feb. 8, 1936, No. 3910. [Class 27] Mechanism for prepaying basic charges.-A prepayment meter has hire or rent charge mechanism which debits a charge against subsequent payments after the supply has been cut off by the meter, adjustable means being provided for limiting as desired the extent of such debit. The rent charge motor, through gearing including wheels b, c on a spindle d, Fig. 1, drives the planet carrier e of a differential mechanism, the sun-wheels f, g of which are rigid with wheels h, i meshing with wheels j, k. The wheel turns a spindle m which drives through a reduction gear a spindle n having a wheel q to rotate a low speed cam r, while a high speed cam j<1> is associated with the wheel j. The cams j<1>, r control switch tripping mechanism as described in Specifications 444,663 and 446,201. The wheel k is connected with one sun-wheel k1 of a differential A, the planet carrier x of which is driven by the meter while its other sun-wheel w<1> is turned by prepayment. The motion of the connected wheels f, h represents prepayment less consumption and less rent charge. When the supply is cut off, the spindle n is still rotated in the direction indicating a debit of rent or hire charge. This spindle carries a disc o having a pin p which, when the debit or arrears of rent charges reaches a certain limit, engages a lever s carried by a spring fulcrum t, the other end of this lever engaging a collar u on the spindle d. The spindle d is thereby moved axially to disengage the wheels c, e so that no further increase in the debit charge is made. The angular position of the pin p relatively to the trip cam r is adjusted by slackening a grub screw securing the boss of the disc o to the spindle n. In a modification, Fig. 2, the disc o is replaced by an arm 2 having a pin 3 which, when the limit of debit is reached, engages a spring 4 resting against an abutment 6. The arm 2 and spindle n is thereby arrested, a friction clutch in the drive from the rent motor to the wheel c slipping. The pin 3 may be arranged to open a switch in the circuit of the motor which is thus stopped or it may close a switch to shortcircuit the motor.
