Title: Improvements in and relating to the stacking of blocks
IPC: B65G57/26
Filed: 1957-11-01
Abstract: 903,440. Load-handling machines. BENNETT, C. L. Dec. 15, 1958 [Nov. 1, 1957], No. 33718/58. Divided out of 903,439. Class 78 (3). [Also in Group XVII] Bricks or the like are formed into openwork stacks by separating rows into ranks comprising groups of bricks with spaces between them, the ranks are assembled to form a layer and the layer placed on a receiver which is rotated 90 degrees to receive the next identical layer. Stacking.-Rows 12a- 12c of bricks from a forming machine 10 are fed on to a pair of identical platforms 13, each comprising panels 14-17. The platforms are drawn apart by hydraulic means 32, Fig. 4, to separate each row of twelve bricks into two rows of six and the panels are then separated, in a manner similar to that described in Specification 781,264, so that each row becomes a rank consisting of single bricks at either end and two pairs of bricks between. The two layers formed on the tables are gripped by means substantially as described in Specification 781,263 and transported to the receivers 18a, 18b or on to pallets &c. on the receivers. The receivers are then rotated through 90,degrees and a further layer added to each. This is continued until the stack is formed. Loading of stacks.-The stacks are loaded on a truck 21 for transport to a drying kiln by a lift fork device 20. This comprises a trolley 55 running on rails 53, 54 on a turntable 50. The fork tines are carried on a member 59 movable vertically on the trolley and may consist of two spaced rows 19, 19<SP>1</SP>. The tines engage a stack as shown in Fig. 3, raise it, the trolley withdraws and the turntable swings so that on advance of the trolley the stacks are placed over the truck, which may be two tiered, and are then deposited on it. Channels 24, Fig. 3, on the receivers 18a, 18b, and similar channels on the truck permit entry and withdrawal of the tines 19, where stillages &c. are not used.

Title: Electrolysis of aluminium
IPC: C25C3/20
Filed: 1973-07-16
Abstract: 1413726 Automatic control of meltelectrolytic aluminium production SWISS ALUMINIUM Ltd 16 July 1973 [18 July 1972] 33735/73 Heading C7B [Also in Division G3] In a known type of cell for recovery of aluminium by electrolysis of aluminium oxide in a fluoride melt, the electrical energy supplied to the cell is measured over successive intervals of time and compared in each interval with a desired value, any differences being added to form a cumulative total, the cell average interpolar distance being varied, if the total exceeds a pre-set value, to establish a rate of energy supply to the cell approaching a predetermined rate. In the embodiment, a computer calculates the energy supplied from the product of the cell base voltage, cell current and the sampling time interval, and calculates the energy supply desired value according to the type and condition of the cell. The average interpolar distance may be varied by moving all the cell anodes or by moving only the anode whose interpolar distance is less than that of the other anodes. The cumulative total can be returned to zero after each adjustment of the interpolar distance, which may be made in steps.

Title: A process for the production of a fertilizer compound
IPC: C05F1/00
Filed: 1959-10-07
Abstract: A fertilizer is produced by subjecting waste material such as leather, hide or the like or wool to the effect of steam at a pressure of 8 to 15 atmospheres to reduce the material to a semi-liquid condition, concentrating by heating, reducing the water content to 2 to 10%, and then cooling the product so formed.

IPC: C11C3/00
Filed: 1927-12-15
Abstract: 292,574. Erba Akt.-Ges. June 23, 1927, [Convention date]. Sulphonated oils.-Oils are sulphonated by sulphuric acid in the presence of substances capable of giving off oxygen in acid solution, such as hydrogen peroxide, alkali or alkaline earth peroxides, persulphonic acids, alkali persulphates, alkali percarbonates, alkali perborates, peroxides of organic acids such as acetyl peroxide or benzoyl peroxide, compounds of hydrogen peroxide with organic bodies such as benzoic acid and urea. Oils prepared in this way are preferably not washed but neutralized directly, the sulphates being thrown down by the addition of watersoluble alcohols such as ethyl alcohol, methyl alcohol and isopropyl alcohol. An example is given in which oil is sulphonated by sulphuric acid in the presence of hydrogen peroxide stabilized with phosphoric acid or a corresponding quantity of sodium. potassium or ammonium persulphtae, percarbonate or perborate. The reaction mixture is neutralized and an alcohol is added. The Specification as open to inspection under Sect. 91 (3 (a) also states that the neutralization process described may be used with other sulphonated oils and in all sulphonating processes in which, as well as sulphuric acid, aromatic or hydroaromatic sulphonic acids or their alkyl derivatives are employed.

Abstract: 649,786. Diplex radio signalling ; superheterodyne receivers. PHILIPS ELECTRICAL, Ltd. Dec. 31, 1947, No. 35181. Convention date, Oct. 10, 1939. [Class 40 (v)] [Also in Group XL (a)] The invention relates to circuits for separating two or more oscillations applied to the grid 3 of a valve (for example the sound and vision signals in a television receiver) in which the two oscillations are derived by selective circuits 18 and 12 connected respectively to the anode 6 and one or more secondary emitting electrodes 5. According to the invention the valve has an anode in the form of a plate located outside the path of the primary electrons, and a suction grid 36 parallel to and in front of each of the secondary emitting electrodes, the latter being connected to the cathode either inside or outside the envelope through a low impedance 40 and either inside the envelope through a resistance or choke to the anode or outside the envelope to a high positive potential. The valve may operate in addition as a frequency changer, in which case local oscillations are also applied to the grid.

A table 8 slung, from wheels 13, beneath casting-supporting rollers (4), Figs. 2, 3 (not shown), with end wheels 6 running in rails 3, travels in the same direction as the horizontal movement of a continuous casting 1 (and in synchronization with the movement of a cutting torch 2 and of the rollers) to catch an ingot 11 cut off and dropped from the casting 1. The table wheels 13 run on transverse rails 7, supported by hangers from members (5) which couple the spindles of the rollers 4, the rails having downturned ends (7<SP>1</SP>), Fig. 3 (not shown), so that the table 8 is tipped, to slide the ingot 11 into a truck (12), when the wheels 13 run towards the end (7<SP>1</SP>). This lateral translation of the table 8 is caused when wheels 10 mounted on a table bracket to embrace and run on a guide rail 9 parallel with the casting 1, encounter an inward bend 9<SP>1</SP> of the rail. As the rollers 4 shuttle back, the bend 9<SP>1</SP> causes the table 8 to run back under the rollers. The table may tilt the ingot on to a shoot or it may be removed by a pneumatic slide without tilting.
