Abstract: 843,045. Gas liquid contact apparatus. MONTZ, 0., [trading as MONTZ K.G., J.]. March 18, 1958 [March 18, 1957 ; Sept. 27, 1957], No. 8671/58. Class 55 (2). An internal structure for conducting a liquid trickling downwards inside a gas-liquid contact column comprises narrow ribbons which are twisted into a helical coil. In a vacuum column, vapour enters the lower chamber 1 at 7 and, after passing upwards through the helically wound ribbons or wires 12 condenses on the insides of tubes 6 to trickle down on to the stirrups 11 and thence on to the wires for interaction with the rising vapours. The opening 8 may be connected with a vacuum system and may be used for the withdrawal of vapour. Two or three sets of helically-wound wires may be used in close proximity so that the liquid runs along the spaces between the wires by cavitation. The ribbons may be made from a flat strip of metal which is longitudinally slotted at 13 (Fig. 6) at spaced intervals to form ribbons 15, 16 connected by bridges 19 which are in staggered relation, the strip then being coiled to form a helix arranged so that a liquid passing down one ribbon completes a full turn of the helix before encountering a bridge to take it on to an adjacent ribbon.

Abstract: 433,388. Prepayment electricity meters. CHAMBERLAIN & HOOKHAM, Ltd., and JAMES, S., 4, New Bartholomew Street, Birmingham. March 20, 1934, No. 8694. [Class 27] [See also Group XXXVII] A mercury switch a mounted on a lever b is closed after prepayment and retained by a pivoted catch d held against a stop i by a spring h. The catch is released automatically at the end of a predetermined time by an arm e rotated by a synchronous or other motor, or by clockwork, or, after a predetermined consumption, by a current meter. If the current taken exceeds a predetermined limit, an electromagnet f is energized and releases the catch d by attracting an armature m mounted thereon. When the switch is tripped by the action of an excessive current, the normal supply may be restored by insertion of another coin, the residue of the interrupted supply being thereby also made available, or by a finger lever for re-engaging the switch. In a modification, the excessive current heats a coil controlling a bi-metallic or other thermal switch in the circuit of the eloctromagnet f.

Abstract: 225,116. Wade, H., (Mills Novelty Co.). April 7, 1924. Kinematograph apparatus. -- The shutter is carried by a lens cell which is oscillated so that it has a limited movement with the image carrier, the shutter being caused to move in one direction across the exposure aperture by the momentum imparted to it by the oscillation. The Figure shows the invention applied to an apparatus having a rotating disc film as described in Specification 225,115. The film disc 43 has a spiral groove with a projection therein for each image, as described in Specification 182,197. The lens cell 54 is caused to vibrate by the engagement of a finger 60 with the projections in the groove as described in Specification 225,115, and is connected to a curtain 69 by means of a bellows 73 secured around an opening therein. The shutter is mounted within the bellows on an arm 79 pivoted on a tongue 78 projecting from the lens cell, and comprises a curved plate having an aperture 81 and a weight 80. When the lens cell is stationary the aperture 81 is kept out of register with the exposure aperture in a curved plate 77 by a spring engaging the tongue 78 and arm 79, but the vibration of the cell causes the shutter to vibrate across the aperture, its movement in one direction being due to its inertia and in the other direction to the spring. A cord 98<a> passing through a lug 98 enables the lens cell to be pulled away from the film disc.

[Class 120 (ii)] In a spool winding machine of the kind wherein the spools are mounted on vertical spindles to which motion is imparted by friction driving wheels which act upon driven discs on the spindles, each driven disc is made bodily movable heightwise and means are provided for lifting the said disc out of contact with the corresponding friction wheel, actuation of the said means for this purpose being automatically controlled by an element adapted to be displaced by the thread on a wound spool on the spindle. Thread &c. T from a bobbin 27 surrounded by a transparent casing 29 is led over a guide 31 and thence between guides 32, 33 to the hub of the winding spool 18 positioned horizontally at the top of a vertical spindle 13 driven by a friction wheel 19 through a disc 14 keyed at the lower end of the spindle. The friction wheels 19 of the machine are driven by an electric motor 7, which is adjustable along rods 4, through pulleys 23, 24. The portion 41 of a spring-biased " knock-off " lever, pivoted at 42, is contacted by the wound thread, when a predetermined diameter is reached, and turned to release a spring-loaded vertical catch 51, which, in falling presses on a weighted lever 62 to raise the driven disc 14 from its friction wheel 19 so to stop the drive. The "knock-off lever comprises two parts 43, 44 adjustably held together at 47 so that the diameter of winding at which " knock-off " occurs may be adjusted as required. The catchpin 51 is formed with a cam-faced top portion so that, in falling, the cam will move the lever 43, 44 away from the windings to facilitate doffing. In order that different sized spools may be wound with yarn &c., each spindle 13 may be bodily moved to vary its distance from the " knock-off " lever. The " knock-off " mechanism is reset by a handle 64 or by a dial. A handle 65 is included on the " knock-off " lever so that the operative may manually stop any spindle at will without stopping the others. The spool may be retained upon the spindle during winding by a knurled nut &c. If desired, a plurality of spools may be carried one above another on the same spindle and held together either by a knurled nut or a weight at the top.

Filed: 1931-03-23
Abstract: A sulphonic acid or an acid sulphuric ester containing an alkyl group having more than 12 carbon atoms is added as a detergent to the topping dye bath, when piece goods are dyed with indigo followed by topping with an acid or mordant dyestuff.  The usual separate cleansing operation to render the dyestuffs fast to rubbing is thus avoided.  In an example, a botany piece after being dyed with indigo, is rinsed and dyed in a bath containing Carmoisine WS, acetic acid, Glauber's salt and octadecylsulphuric ester.  The bath is exhausted by adding lactic acid and the dyeing is chromed by means of sodium bichromate.  The following detergents are also mentioned: cetylsulphuric ester, cetylsulphonicacid, octodecenylsulphuricester (obtained by treating oleyl alcohol with sodium pyrosulphate in the presence of pyridine), the oleyl ester of b -hydroxyethanesulphonic acid, cetylsulphoacetate, cetylsulphobenzylether (obtained by the action of benzylchloride on cetyl alcohol in the presence of sodamide followed by sulphonation) and octodecenyl-b -sulphoethylether (obtained by the action of sodium b -bromethanesulphonate on the sodium compound of oleyl alcohol).
