Title: Card index
IPC: B42F17/00
Filed: 1925-05-18
Abstract: 242,184. Rand, J. H. May 18, 1925. Visible card indexes; index cards. - In cardindex devices of the kind wherein a number of card-holders are maintained in overlapping relation on a tray or support, with the edges of the card-holders projecting one beyond another, each card-holder is adapted to carry one or more groups of overlapping cards which are arranged upon it with their edges projecting one beyond another, the cards being either individually supported by the holder or detachably interlocked or connected with each other. The groups of cards may be arranged on either or both faces of the cardholders. Transparent protecting strips which are readily movable to permit access to the cards may be provided on the card-holders for preventing inadvertent engagement of the cards of adjacent card-holders. As shown in Fig. 9, the cardholders 10, provided with lateral tongues 14 on their upper edges to engage beneath the side flanges 16 of a tray, are arranged with their lower edges overlapping to expose primary index slips 30 within celluloid sheaths 19 along the edges, and the face of each card-holder carries two groups of overlapping secondary index cards 20 having oppositely directed tabs or ears 23 and slots 24 by which they are interlocked one with another. The upper card of each group is attached to the card holder by inserting its tabs 23 within slots 28 in the card holder. The protecting strips 45, two of which are shown for each group of cards, may be of celluloid or the like, and are secured to the card-holders by staples 46 at their lower edges, so that they may be beat back to remove or insert a card. The interlocking engagement of the cards may be modified by cutting additional slits 41, Fig. 6, in them to form tongues 40 which overlap the coincident lower edge 22 of the adjacent card 20 and prevent it from bulging at the centre, more particularly when the cards are made of paper or other thin material. In another method of attaching the groups of overlapping cards 31, Fig. 10, to the card-holder 10<a>, two spaced vertical slots 34 are cut in the body of the card-holder, or in a separate card attached thereto, to receive the ears 33 of flaps 32 cut in the cards, each card being thus separately attached to the holder, so that one or more can be detached independently of the remainder. In another modification, Fig. 12, two vertical rows of spaced slots 37 for each group of cards are provided in the body 10<b> of each card-holder to receive tabs 38 on the cards 36.

Title: Improvements in or relating to remote control and supervisory systems
Inventor: BUTCHER VICTOR LEONARD
IPC: G05B19/08
Filed: 1961-04-11
Abstract: 930,337. Electric selective signalling systems. PARKINSON COWAN Ltd. April 11, 1962 [April 11, 1961], No. 13005/61. Class 40 (1). In a system for controlling six pumps according to a preset programme, leads T1-T48 correspond to successive steps in the programme and may be connected by plugs (shown by crosses) either to selected ones of leads 1P1- 1P6 to represent start commands for the respective pumps, or to lead 1PO to represent a special command whereby all pumps which are running at that time are stopped. Master clock 1 pulses magnet CSTM every half hour to scan leads T1-T48 in turn during a day, and at the end of this operation bank CST2 pulses magnet CSDM to step switch banks CSD1-CSD7 so as to select the next group of leads 2P1-2P7 corresponding to the next day, and so on, until on the last day of the week, leads 7P1-7P7 are selected, the contacts of each bank being connected to a corresponding lead in each group. Lamps LT1-LT48 and LD1-LD7 indicate which step of the programme is in progress. Control circuit 2 transmits the signals from CSD1-CSD7 to a remote station where three of the pumps are located in a well and three on the surface. An interlocking arrangement is provided to ensure that the pumps in the two sets are started in the correct order and the total output from the pumps in the well is balanced by that from the surface pumps. In the programme shown for the first day, step 1 starts pumps 2, 4, step 2 stops pumps 2, 4 and starts pumps 1, 5. Step 47 stops all pumps running in step 46 and starts pumps 2, 5. Step 48 replaces pumps 2, 5 by pumps 2, 4, but in this case a command decoder at the remote station senses that pump 2 is required again in step 48 and prevents this pump being stopped by the common stop signal. Signals indicating the operating state of the pumps are received from the remote station and are supplied to a minic diagram 31, and also to a comparator 7 for checking with the commands transmitted. If the programme pattern is repeated on following days, the corresponding groups of leads 2P1- 2P7 to 7P1-7P7 may be dispensed with, the appropriate switches R1-R7 associated with banks CSD1-CSD7 being closed instead.

Title: Improvements in the extracting of tungsten compounds from tungsten ores
IPC: C22B34/36
Filed: 1957-04-24
Abstract: In a process for obtaining ammonium tungstate from tungstate ores or calcium tungstate, an aqueous mixture of said materials with oxalic acid or a soluble oxalate is treated with ammonia. Calcium tungstate may be mixed with an aqueous solution of oxalic acid (whereby some insoluble yellow tungstic acid is formed), digested at 50-100 DEG  C. and aqueous ammonia added.  After further digestion the residue may be removed and filtered hot to avoid precipitation of ammonium paratungstate.  Preferably 3-4 mols. of oxalic acid and 5-10 mols. of ammonia are employed per gram atom of tungsten in the ore. Alternatively the ore may be extracted with ammonium or other soluble oxalate, followed by addition of ammonia.  Thereafter tungstic oxide may be precipitated, e.g. by adding to the filtrate hot hydrochloric acid containing a small amount of nitric acid.  It is said to be known to extract tungsten with hydrochloric acid and with alkali metal hydroxides and carbonates.  A process wherein after extraction with oxalic acid the resultant solution is separated and ammonium paratungstate precipitated therefrom with ammonia, and Japanese Specification 172,961, which describes the extraction of scheelite with oxalic acid, are referred to.

Patent GB-481344-A (GB)
Title: Improvements in or relating to watch timing apparatus
IPC: G04D7/12
Filed: 1937-05-11
Abstract: 481,344. Testing timepieces. NORRMAN, E. May 11, 1937, No. 13380. Convention date, May 12, 1936. [Class 139] In an apparatus for testing chronometers, a movable reference member 6 is maintained in synchronism with a master chronometer by means actuated by a tick - responsive device. A graduated translucent dial 6, Fig. 2, is rotated at 1 r.p. sec. by an electric motor 7 and is maintained in synchronism with a master watch by means of a fixed electromagnet 63 surrounding an armature 64 carried by the dial 6 and coupled with the motor shaft by a low resistance friction clutch 62, the electromagnet receiving shortened electrical impulses from an amplifier in response to the ticks of the master watch. To set the dial, a vapour lamp 19 is. switched into the master watch amplifier circuit, the momentary flashes from it making the dial appear stationary. The dial can then be zeroized by rotating the motor 7 by means of a knob 24. Other vapour lamps 25 receive electrical impulses from the watch under test so that, by setting an adjustable index 26 opposite a zero as it appears on the dial, any apparent movement of the dial can be detected and will indicate lag or lead of the watch under test relative to the master watch. Since it is desirable to cut out alternate ticks of the watches, a device 50, Fig. 3, driven by the motor 7 so as. to revolve once for each two ticks of a watch, is included in each amplifier circuit, contacts 53 being moved by an arm 57 to bear upon a partly insulated section 54. In another embodiment, Fig. 5, the electric motor is mounted on a rotatable gear-wheel 70 and the motor shaft extends below this driving, through bevel and worm gears, a shaft 78 which oscillates an arm 73 carrying a double ratchet 74 and electromagnets 83 and 84, about the centre of a wheel 75. On the upper end of the motor shaft a disc 68, adapted to rotate once for each tick of the master watch and to receive electrical impulses from both amplifying circuits by means of a shoe 93, is provided with conductor points 86 passing close to conductor plates 87, 90 and 91. The plates 90 and 91 are so connected with the master watch amplifier that an impulse passing, for example, from the point 86 to the plate 91 causes the ratchet 74 to be pulled over by the magnet 83, as shown, causing additional rotation of the disc 68. Similarly, an impulse passing to the plate 90 would have a negative effect on the rotation of the disc. Impulses from the watch under test cause a spark to pass between the plate 87 and a point 86 which marks a strip of paper 85. In a further embodiment, Fig. 7, the dial 105 is given corrective rotation on its shaft by a worm 111 and star-wheel 112 which is engaged by one of the arms 113 of an electromagnetically controlled member 115. An arrangement for actuating the control magnets is shown diagrammatically in Fig. 9.

Title: Improvements in or relating to the purification of water
IPC: C02F1/76
Filed: 1955-05-09
Abstract: Chlorophenols, especially trichlorophenols, are obtained by treating phenols-containing waste water, in the acid condition, with chlorine. In one example the waste water is "extracted" by di-iso-propyl ether, acidified, and treated with chlorine.  The water is then "extracted" by a second solvent, e.g. toluene, which will take up not only the trichlorophenols formed but also the original solvent.  The extract containing the trichlorophenols is agitated with an aqueous alkaline solution, the resulting aqueous phase separated and acidified to excess, and the trichlorophenols are crystallized therefrom and filtered.  The chlorination is preferably applied to the whole content of phenols for maximum yield.ALSO:Phenols are substantially eliminated from waste water by treating it, in the acid condition, with chlorine, and separating from the water the chlorophenols thus obtained.  In one example waste water from a coking plant is clarified by aluminium acetate, filtered through sand, and "extracted" with butyl acetate.  The water is then continuously supplied, along with gaseous chlorine, to a vessel where it is agitated by a turbine.  The water continuously leaving the vessel is freed from its chlorophenols by treatment with a solvent.  In another example the waste water is "extracted" by di-iso-propyl ether, acidified, and treated with chlorine.  The water is then "extracted" by a second solvent, e.g. toluene, which will take up not only the trichloro-phenols formed but also the original solvent, leaving phenol-free water.
