Title: Supervising power supply systems
IPC: H02J3/00
Filed: 1975-09-23
Abstract: 1516999 Measuring voltage INTERNATIONAL BUSINESS MACHINES CORP 23 Sept 1975 [12 Dec 1974] 38899/75 Heading G1U In monitoring a supply system which provides a number p of supply voltages of nominal value U si , where i = 1 ... p, which each have different upper and lower limits U SPi  and U SNi , the actual supply voltages U i  are multiplied by corresponding normalizing factors Uo /U Si  and compared to a reference value U REF , which steps through all the normalized limit values i.e. U SPi . U O /U Si  and U SNi . U O / Si  and respective outputs are produced if the normalized actual values lie outside the normalized limit values. As shown in Fig. 2 the normalized actual values U NO1,  U NO2  may vary with time. The common normalized supply voltage Uo lies between respective pairs of normalized limits UEP2, UEN2 and U EP1 , U EN1 . The reference value UREF is repeatedly stepped through those values until e.g. at T6, U NO1  is detected as exceeding its upper limit U EP1 . A scanning unit  then adjusts the reference generator, Fig. 1 (not shown) to provide a series of fine steps during T7 which enables the actual normalized level of U NO1  to be determined. The stepping programme then recommences. If several voltages are being monitored which have equal relative deviations allowable, only two reference levels are required after the normalizing step, Fig. 3 (not shown). The arrangement may be used to monitor voltages in. a computer, Fig. 4 (not shown), where the CPU monitors the compared voltages, controls the reference generators, provides a visual display and also may control the power supply to bring the levels back within required limits, or to switch off any affected apparatus.

Title: Process for the separation and recovery of substantially pure aluminium chloride
IPC: C01F7/56
Filed: 1966-09-02
Abstract: In a process for concentrating an aqueous solution containing AlCl3 and other metal chlorides by evaporation to obtain crystals of AlCl3.6H2O, a portion of the mother liquor is continuously withdrawn at such a rate that the concentration of other metal chlorides is sufficiently low to prevent contamination of the AlCl3.  The process is repeated at least once, and possibly 2 or 3 more times, using as feed the withdrawn mother liquor, to obtain impure AlCl3 which is recycled with the feed to the previous step.  The mother liquor may be withdrawn separately from the crystals and treated to remove solids (filtrate from the crystals being recycled), or may be withdrawn together with the crystals.  Part of the initial feed may bypass the first evaporator.  Graphs are given relating the concentration of Fe and Cr chlorides in the mother liquor to the amount of these chlorides in the product, and examples are given of the amount of mother liquor that must be withdrawn in the first and second evaporators if a certain concentration and product purity is to be maintained.  The AlCl3 may be calcined to give Al2O3 and HCl, and the final mother liquor is evaporated and the residue calcined to recover HCl.

Abstract: 1,152,364. Spinning. COURTAULDS Ltd. 23 Sept., 1965 [23 Sept., 1965], No. 40625/65. Headings DID and D1W. A yarn of varying colour character along its lengh is produced by feeding two rovings or tops (or groups thereof) of different colour or dyeing affinity to a drafting system through a gripping device through which one roving can pass freely while the other roving is gripped, and vice versa, and intermittently changing over the gripping device so that the two rovings are alternatively gripped and thus alternatively withheld from the drafting system. The rovings pass from the device to the drafting system through a tubular guide which holds the broken end of a roving gripped by the device. When the gripping device changes over, the end of the roving which is being released is caught up and fed to the drafting system by the other roving before the other roving breaks. The gripping device may comprise a pair of intermeshing toothed rollers, one roller being axially divided into halves, each half being only toothed in opposed quadrants and a toothed quadrant in one half being aligned with a plain recessed quadrant in the other half. The rollers are intermittently rotated by a cam drive from the drafting rollers. Alernatively the gripping device may comprise a cylindrical member having two diametrical bores which are disposed at 90‹ to each other, and through which the rovings can pass freely, the member being rotated by for example a cranked arm controlled by a spring and solenoid - between a first position in which an end of one bore is adjacent a roving gripping platform and a second position in which an end of the other bore is adjacent the platform. The gripping device may be changed over at regular or random intervals.

Abstract: 406,670. Cash registers. NATIONAL CASH REGISTER CO., Dayton, Ohio, U.S.A.-(Assignees of Green, C. W.; 106, S. 4th Avenue, Ilion, New York, U.S.A.) Aug. 31, 1932, No. 24281. Convention date, Aug. 31, 1931. [Class 106 (i).] Printing on bills and like inserted material.-In a cash register of the key set and operated type having means for printing on an inserted slip, means are provided for sensing the presence or absence of a slip and for preventing the continuance of a machine operation when no slip is present. The invention is described as applied to a cash register of the kind disclosed in Specifications 135,465 and 157,824, [both in Class 106 (i)]. As shown in Figure 3, the slip is inserted between a table 400 and plate 403, and its presence is sensed by a feeler 503 mounted on one arm of a lever 500. The other arm of the lever terminates in a hook 504 that, when no slip is present, co-operates with a shoulder 514 on a disc 513 rigid with the main shaft 26 to interrupt the operation of the machine. The lever is normally held in the position shown in dotted lines by a pin 510 on a lever 507 that is urged in clockwise direction by a spring 508. At the beginning of an operation, a pin 515 on the disc 513 rocks the lever 507 counterclockwise and allows the lever 500, under the action of a spring 509, to rock clockwise and engage the feeler with the slip, if present. The end of the feeler is provided with teeth to prevent the withdrawal of the slip during the printing operation. Immediately the printing operation is finished the pin 515 passes the end of the tail 512 of the lever 507 and the feeler is disabled. In a modified form of the device, Fig. 6, the feeler 623 is carried by one arm of a lever 600, the other arm of which is connected by toggle links 603, 604 and pivot 606 to an arm 607 pivoted to the casing. A pin projecting laterally from the pivot 606 bears on the periphery of a cam disc 610, and a pin projecting laterally from the centre pivot 605 of the toggle lever bears against a pivoted arm 630 that terminates in a hook 613. In the event of there being no slip present, the toggle is moved upwardly by the cam without breaking and the hook 613 remains in the path of a shoulder 612 of the disc to arrest the main shaft. If, however, a slip is present, the toggle breaks and rocks the arm 630 into inoperative position against the action of its spring 616.
