Abstract: 967,850. Locating conductive or magnetic bodies. T. I. (GROUP SERVICES) Ltd. Sept. 30, 1960 [Sept. 30, 1959], No. 33131/59. Heading G1N. In an apparatus for detecting each end in turn of a length of inductive material, wherein the approach of the leading edge of a length of the material being fed to a drum is detected by one coil 11 adjacent the drum, and the passage of the trailing edge is detected by a second coil 12, spaced along the path of the material, which is switched into circuit in response to the output from coil 11, the coil 11 is withdrawn from its normal position by the leading edge signal in order to prevent its being fouled by the build up of inductive material on the drum. Coils 11-12 are connected in an A.C. energized Wheatstone bridge the output of which is arranged to operate a relay 23 through an amplifier 21 and detector 22. The relay is energized by the arrival of the leading edge, and transfers the indication of presence to coil 12 which holds the relay until the passage of the lagging end. The signals from the two coils may be used to give an indication of length. Coil 11 may be mounted centrally of the wind-on drum and coil 15, which serves as a bridge balance may be adjacent one end, the two are mounted so that both are withdrawn in response to the energization of relay 23. Coil 12 may be retracted by the passage of the tail end, in order to clear the way for the introduction of a fresh strip.

Abstract: 1,065,738. Hydraulic machines. INDUSTRIEWERKE KARL-MARX-STADT, VEB. Aug.14, 1964, No.33260/64. Heading F1P. A hydraulic control system, Fig. (not shown) for rapidly halting the movement of e. g. a machine tool table driven by hydraulic fluid supplied by a radial piston pump (1), comprises a gear pump (21) supplying via non-return valves (23, 24) an accumulator (25) and via a line (27) a spool valve (12), the arrangement being such that when the table is to be halted pump (21) is stopped and valve (12) is displaced to the right whereby lines (10, 11) are pressurized by the accumulator (25) and pistons (5, 6) move together to lock a control piston (4) in a position corresponding to zero output of pump (1). The halting of the table may be initiated by the detection of a fault in the system arranged to stop the pump (21) and deenergize a solenoid associated with the valve (12). The fall in pressure in a line (20) resulting from stopping the pump (21) allows a piston (19) to move to the right thereby connecting the accumulator (25) via lines (26, 17) and the valve (12) to the pistons (5, 6). In normal operation, a changeover valve (9) controlled by electrical switches actuated by the table, alternately supply fluid to lines (7) and (8) leading to opposite ends of the control piston (4) of the pump (1).

Abstract: 282,738. Axtell Research Laboratories, Inc., (Assignees of Axtell, F. C.). Dec. 27, 1926, [Convention date]. Mineral oils, purifying-The sulphur content of oils such as gasoline, kerosene, lubricating oils, or cracked distillates, is reduced by treatment with a reagent comprising sulphuric acid, preferably fuming, heated with excess of aromatic hydrocarbon preferably commercial benzene and its homologues at room temperature, whereby an acid sludge containing most of the sulphur is formed, and the aromatic and unsaturated content of the oil is unattacked. Concentrated sulphuric acid may be added to the reagent as required to react with the unsaturated portion. The oil is separated from the acid sludge, which may be largely freed from sulphur by adding water. The oil, preferably after treatment with a basic clay, which is then separated, is shaken with a strong aqueous alkali solutions. After separation, the oil is redistilled, and sulphur not separated in the acid sludge remains largely in the still. By treating an oil with an end boiling point of 225‹ C. with 12¢ lbs. of reagent per barrel, and blending with about 20 per cent of kerosene distillate and distilling wtih steam over caustic potash, the sulphur content is reduced from 0.68 per cent to 0.11 per cent. Commercial toluene and xylene may be added to or replace the benzene to raise the boiling point. The fuming sulphuric acid may contain enough sulphur trioxide to combine with any water formed on the formation of the benzene sulphonic acid. Crude distillates from cracking units may be first and immediately washed with caustic soda or sodium plumbite. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the use of selenic acid in place of sulphuric acid. This subjectmatter does not appear in the Specification as accepted

Abstract: 1460995 Tone receivers; frequency-to-digital conversion INTERNATIONAL STANDARD ELECTRIC CORP 6 Aug 1974 [16 Aug 1973] 34555/74 Headings H4K and H3H In a receiver of the type in which an incoming frequency signal of a predetermined group of frequencies is detected by counting clock pulses over a predetermined plurality of cycles of the signal as counted by a zero crossing counter, a pre-check is performed over a small number of cycles and the main check only proceeds if the pre-check is positive. The apparatus comprises a clock pulse counter TZ having first pairs of outputs, e.g. Z1, Z2 coupled to bi-stable devices, e.g. F1 for defining a range of counts for each of the frequencies to be detected. Each frequency also has allocated thereto a second pair of outputs, e.g. Z11, Z21 coupled to a bi-stable device, e.g. F 11 for use in a pre-check over a predetermined small number of cycles. The production of a first spike by circuit ND corresponding to a zero crossing sets bi-stable NF to gate clock pulses to counter TZ, and counter NZ counts the zero crossing spikes. Counter NZ produces an output on wire AV after a predetermined low number of cycles, e.g. 3, which causes bi-stable circuit SF to set if the count is in a range corresponding to any of the pre-check count ranges. All the counters are reset and bi-stable circuit SF inhibits gate SG. The main check is then performed over the predetermined plurality of cycles, on the termination of which counter NZ produces an output on wire AH to gate the output of any set bi-stable device F1, F2 &c. to a corresponding output 01 &c. The arrangement may be modified to allow two pre-checks to be performed, the main check only being performed if both pre-checks are positive. The band width for the pre-checks is made greater than that for the main check by having wider pre-check counting ranges than main check ranges. Two such arrangements may be incorporated in a 2 (1 out of n) tone receiver for telephone tones (Fig. 1, not shown). Reference has been directed by the Comptroller to Specification 1,221,890.
