Title: Process for coating metallic objects with other metals
IPC: C23C2/02
Filed: 1947-12-01
Abstract: 676,198. Coating with metals; modifying metallic surfaces; annealing. ALFERIEFF, M. Dec. 1, 1947 [July 31, 1946], No. 31653/47. Classes 72 and 82(ii) Metallic bodies are coated with aluminium, zinc, lead, cadmium, tin or an aluminium alloy, by heating the body to a temperature from 35-180F lower than the annealing temperature of the body in a reducing atmosphere, then expelling occluded active gases by heating the body at the annealing temperature whilst subjecting the entire surface to the continuous flow of a practically inert atmosphere, and whilst protected by the inert atmosphere passing the body into a molten metal coating bath. The reducing atmosphere may be of hydrogen containing not more than 30 per cent of water vapour and the inert atmosphere may consist predominantly of nitrogen but may contain just sufficient hydrogen to counterbalance the effect of air penetration. As shown in Fig. 1, a degreased steel strip 1 passes through a furnace 4 having two heating chambers 5, 6, the former of which may be heated to 1470-1670F and the latter to 1510-1710F, the reducing atmosphere being passed into the chamber 5 at 9 and leaving at 10 and the inert atmosphere being circulated by a pump through the chamber 6 and an extension thereof forming a cooling chamber 11 and through a regenerating apparatus 15. The strip is cooled in the chamber 11 to 1100- 1280F and passes into a pure aluminium bath 12 maintained at a temperature not exceeding 1290F. Before the strip has cooled below 300F and preferably immediately after solidification of the coating, it may be lightly rolled at 16 or, during cooling or after passing through the rolls 16, it may pass through muffles 17 to permit gradual cooling to 700-400F over a period of 2-5 minutes whereafter it may be lightly rolled at 19. In a modification, Fig. 2, a nitrogen atmosphere containing 20 per cent of hydrogen is introduced at 20 into the cooling chamber 11 the end of which is immersed in a molten lead bath 21, the aluminium coating bath 22 floating above the lead bath in the container 23: to accelerate cooling, a water jacket is provided around the chamber 11. Pure nitrogen is fed into the heating chamber 6 at 25. After passing through the cooling bath and before cooling, the strip is heated in the furnace 26 to 1290-1830F for a few seconds until a blackish lustreless coating is obtained. In a further modification, Fig. 3, the aluminium coating bath 29 floats in the bell mouth 28 of the chamber 11 on a lead bath 27 through which the coated strip passes: in this form, the formation of a pure aluminium layer is prevented, the coating consisting exclusively of ironaluminium alloys.

Title: Improvements in machines for grading eggs by weight
IPC: B07C5/22
Filed: 1934-11-05
Abstract: 446,753. Endless - belt conveyers. BINGHAM, G. C., The Friary, Maldon, Essex. Nov. 5, 1934, No. 31698. [Class 78 (i)] [See also Group XVIII] In a machine for grading eggs &c. by weighing, the eggs are brought to the balances 12 by means of a conveyer belt 24 provided with circular holes 25 into which the eggs are placed. As the eggs are advanced, they roll along a rubber strip 27 of less width than the diameter of the holes and are caused to position themselves with their long axes at right angles to the direction of travel. The leading egg falls into a pivoted V-shaped carrier 32 which is rocked by a cam 38 on a rotating table 10 so as to drop the egg on to two pivoted flaps 43 (shown open). The pivoted flaps are then opened by the cam to drop the egg gently on to the balance. The carrier 32 and flaps 43 may be dispensed with.

Title: Improvements in or relating to electrical storage of information
IPC: H03K23/82
Filed: 1946-10-25
Abstract: 619,155. Telephone systems. STANDARD TELEPHONES & CABLES, Ltd., and RIDLER, D. S. Oct. 25, 1946, No. 31709. [Class 40 (iv)] [Also in Group XL (c)] A set of discharge tubes arranged in pairs to form a binary counter comprises means whereby the changeover in conducting condition in any binary denomination in response to transfer from the lower denomination can be effected in response to any changeover in the lower denomination. An incoming call on the line U1, U2 seizes the repeater by energizing relay A which operates relay B to mark the repeater busy over a wire U9, and discharges a condenser C8 to trigger the cold cathode tubes CT1, 3, 5, 7 in a binary counter. A train of impulses from the calling station releases and re-operates the relay A a corresponding number of times, contacts a2 pulsing this digit to the counter by discharging condenser C1 at each impulse. The first pulse triggers tube CT2 and extinguishes tube CT1. The second pulse retriggers tube CT1 and extinguishes CT2, passing a further pulse to the next pair of tubes through a biassed rectifier MR1, which conducts only when the cathode potential exceeds the bias. In a similar manner, transfer can take place at the fourth and eighth pulses to the higher pairs of tubes. The first release of relay A operates relay C which remains operated during the train of impulses and operates relay CC, which locks. At the end of the train of impulses, relay C releases slowly and removes earth from the line BL to decrease the bias on the rectifiers MR1-4, the release of C also discharging condenser C1 to apply an impulse to the counting train, all the rectifiers become conductive and the whole train changes over. to register the complement with respect to the capacity of the counter. When the synchronized machineoperated loop springs 1, 2 next close, the impulse guard relay IG operates and locks to release relay CC slowly to restore the original bias to the rectifiers. While the springs 2 are still closed, contacts ig7 close to discharge the condenser C1 and apply an additional pulse to the counter. Each opening of springs 1 now sends an impulse over line U3, U4 and each closure of springs 2 sends a pulse to the counter until the capacity of the counter is exceeded and a pulse passes to a further tube CT9 which ionizes to operate a cathode relay T which locks up, disconnects tube CT9 and shortcircuits the springs 1 to prevent sending further impulses to line. The circuit then returns to normal. In a modification, instead of reversing the counter train, the bias connection is switched from point W to point Y. The rectifiers may be replaced by neon tubes.

Title: Improvements in or relating to preparation of attrition resistant alumina
IPC: B01J23/24
Filed: 1955-11-11
Abstract: Eta alumina suitable for fluidized catalyst supports in hydrocarbon conversions in the presence of hydrogen is prepared by hydrolysing an aluminium alcoholate, ageing the resultant slurry to form b -alumina trihydrate, mixing said trihydrate, after drying if desired, with an alumina hydrosol to form a composite slurry, preferably containing 3-10 weight per cent of solids which is then dried and calcined.  If desired the product may be obtained in the form of microspheres of 20-80m  diameter form by spray drying the composite slurry.  In the initial hydrolysis 1-8 volumes of water per volume of alcoholate solution, e.g. as formed in situ in petroleum naphtha, may be employed, and 0.5-10 per cent of ammonia may be present in the water; ageing may take 40 hours or more.  Thereafter the slurry, which may be partially filtered or centrifuged to provide a suitable solids content, or the trihydrate after separation and drying, is mixed with alumina hydrosol, and may comprise 40-90 per cent of the alumina in the mixture.  The hydrosol may be prepared by hydrolysing an aluminium alcoholate solution in petroleum naphtha with dilute acetic acid containing 0.5-5 per cent of acetic acid at 70-210 DEG  F., separating the alcohol &c. layer formed and removing the residual alcohol &c. by steam stripping.  (Such a sol on drying alone at 212-280 DEG  F. is said to yield a -alumina monohydrate.)  The composite slurry is dried and calcined at 900-1300 DEG  C. for 1-6 hours to give attrition resistant c -alumina.  Catalytic materials which may be incorporated in the alumina are molybdic oxide (5-15 per cent), chromic oxide (10-40 per cent), cobalt molybdate, nickel-tungsten sulphide, and platinum group metals (0.01-1 per cent), e.g. platinum (e.g. by impregnating the chloroplatinic acid) and palladium (0.05-5 per cent).  Small amounts of silica sol, zirconia, potassia, magnesia and/or calcium oxide may be added to the composite slurry as stabilizers and promoters.
