Title: Improvements in or relating to treatment of sulphur
Inventor: HAIMSOHN JEROME NEWTON
IPC: C01B17/12
Filed: 1956-06-08
Abstract: Carbon disulphide-insoluble sulphur is stabilized by the presence of a mono- or di-substituted ethylene of the formula R1R11C=CH2, wherein R1 is an alkyl, alkenyl, aryl, alkaryl, aralkyl or substituted aryl group and R11 is R1 or hydrogen, and wherein said substituted ethylene contains 4-18 carbon atoms.  0.2 per cent of stabilizer may be present.  Stabilizers specified are isoprene, chloroprene, butadiene, dodecene, tetradecene, octadecene, dicyclopentadiene, indene, 1 - vinyl - 3 - cyclohexane, styrene, p-methyl styrene, 2,5-dichlorostyrene, vinyl toluene, p-vinyl biphenyl, divinyl benzene, allyl benzene.  The stabilizer may be present during the production of the insoluble sulphur or may be added afterwards. In the production of insoluble sulphur by the interaction of sulphur dioxide and hydrogen sulphide in aqueous solution, the stabilizer is preferably added to the sulphur produced.  In its production by quenching liquid or vaporous sulphur in carbon disulphide or aqueous acid, the stabilizer may be added, prior to the quenching step, to the quenching medium or the sulphur to be quenched, or, after quenching, to the quenched slurry, either immediately or after the sulphur has hardened.  Other methods of production specified are spraying liquid carbon disulphide into vaporous sulphur, and passing vaporous sulphur into an aqueous solution containing an oxidizing salt.  The stabilizer may be introduced into a wet sulphur cake during the final wash with carbon disulphide, or into powdered sulphur by passing vaporous stabilizer over or through the sulphur.

Title: An improved machine for tying objects with wire
IPC: B65B13/28
Filed: 1920-07-02
Abstract: 145,761. Warwick, R. M. Feb. 28, 1915, [Convention date]. Twisting wires together; shearing-adjuncts. - A machine for tying-up the puckered mouths of bags, bundles of fibre, sticks, bottles, jars, boxes, &c. with wire has mechanism, preferably controlled by the object to be tied, adapted to contract the tie to fit the object after the wire has been fed around the object through a guide, preferably of horse-shoe shape and clamped, and mechanism for twisting and severing the wire and bending its ends inwards. The invention is described with reference to a machine for tying the mouths of bags for cement, flour, &c., wherein the bag is fed to a device for puckering the mouth and thence to a device for looping wire round the mouth, tensioning it, severing the wire from the supply, twisting the free ends to form a tie, and delivering the tied bag. As shown, the mouth of the bag is passed between spaced members 116, Fig. 2, and is forced by a plunger 118 against projections 113 on radial plungers 105 mounted in a periodically-rotated member 101. When the plunger 105 is forced inwards, arms 107 are closed, to pucker the mouth of the bag, by engagement with abutments on the member 101. The bag is carried by the member 101 to the tying-device which is situated diametrically opposite to the spaced members 116. When the bag is presented to the tying-mechanism, semi-circular guides 47, 48 are swung down into position to embrace the mouth of the bag. Wire from a supply is then fed by engaging segmental members 11, 12 on driven gear-wheels 2, 3 to a tube 14 on a rotatable head 16, Fig. 4, having an eccentric exit for the wire to cause it to pass around channel portions 49, 50 in the guides 47, 48. The free end of the wire is gripped by vice members carried by the head 16 and the body portion of the wire is engaged by segments 73, Fig. 2, on spring-controlled toothed quadrants 69, 70 to tighten the loop. After separation of the loop-forming guides 47, 48, the body portion of the wire is gripped by a pair of vice members, and the head is rotated through three revolutions to twist the ends of the wire together. The rotation is effected through a toothed quadrant 84 mounted on the gear-wheel 3 and adapted to engage a bevel-wheel 22 ccnnected by gearing 20, 19 to the head 16. The free end of the loop of wire is engaged by a bent lever 95, Fig. 4, on a reciprocating slide 91 which bends it over a pin 46 on one of the vice. members. On the return motion of the slide, a cutter 97<1> carried thereby, severs the other end of the loop from the body of the wire and a second bent lever 95 bends it about a pin 46 to form a " key " to the tie, as shown in Fig. 17. The wire-engaging members 73, 12 are normally separated from the complementary members 73, 11 so that they do not grip the wire, but are moved into action, if a bag is presented to the tying-device, by the engagement of the bag with a lever 125<1>. If no bag is presented, wire is neither fed to, nor retracted from, the tying-device.

Abstract: 272,352. Marks, E. C.R., (Ingersoll-Rand Co.). July 20, 1926. Auxiliary gear rods; stroke, varying; regulating delivery by opening by-passes.-In a fuel pump for internal-combustion engines, the fuel is delivered by the plunger 13 past a valve 19 into a chamber 20, from which part of it passes by a pipe 6 to the engine while the remainder is by-passed through a valve 21 and pipe 22. The valve 21 is opened at a variable point in the delivery stroke by a lever 23 operated by the plunger driven through links 27, 25 and carrying an adjustable screw 29 which opens the valve when the lever 23 engages a fulcrum roller 24. The roller 24 is carried by an arm 28 which may be rocked by governor or hand to vary the position of the roller and thereby the moment at which the valve 21 is opened. A rod 30 on the arm 28 engages a pin 31 on the lever 23 and holds the valve 21 permanently open when the roller 24 is moved to its limit. The roller 24 may be moved out of alignment with the lever 23 if it is desired to keep the valve 21 permanently closed. The arm 28 may be rocked by a governor 34 through rod 35 and arms 36, or by a hand-wheel 12 and linkwork 38, 39. The pump may be operated by a hand lever 17 resting on an adjustable stop 17<a> which limits the return stroke.

Title: Refining pig iron
IPC: C21C5/56
Filed: 1965-04-30
Abstract: <PICT:1097811/C6-C7/1> Pig iron is refined in a vessel e.g. a converter by top blowing an oxidizing gas, such as oxygen containing slag-forming materials e.g. lime or limestone in suspension, on to the molten pig iron covered with a foaming slag which is at least partly removed from the vessel during at least part of the refining operation, e.g. through a slag-overflow opening 2 in the side of the vessel 1 (Fig. 4).  The top blowing may be effected with a lance 5 placed between the opening 2 and the vessel axis and producing a jet inclined downwards away from the opening.  A cover 4 is preferably provided to pressurize the inside of the vessel.  An opening 3 may be provided at a level higher than that of opening 2 for tapping molten iron when the vessel is turned down. Foam-promoting materials such as iron or chromium oxide, graphite or magnesia may be introduced into the vessel.  The slag being removed preferably contains 20% or less of iron and at least 14% P2O5.  Silica or other Si compound may be added to the slag after removal to keep the ratio of SiO2: P2O5 in the slag above 0.3.  The slag may overflow continuously from the refining vessel into a decanting vessel, then into a slag container. Also the metal may overflow continuously into a secondary top blowing refining vessel by adding metal to the primary refining vessel.  A three-stage cascade continuous process may be used. Scrap may be added to the refining vessel.  The slag removed may be granulated pneumatically or by liquid jets.

Title: Improvements in or relating to control arrangements for telegraph transmitters
IPC: H04L27/10
Filed: 1946-06-18
Abstract: 613,605. Multiplex telegraphy. STANDARD TELEPHONES & CABLES, Ltd., and ARMSTRONG, L. J. HEATON-. June 18, 1946, No. 18256, [Class 40 (iv)] [Also in Group XL (b)] A remote control system for a telegraph transmitter comprises a control station having an oscillator which may be switched on and off and may be keyed to give different frequencies for marking and spacing and at the transmitter location means responsive to the reception of the oscillator wave of either frequency for switching the transmitter to its operative condition and means responsive to the frequency of the oscillator wave for keying the transmitter. The system shown comprises a multi-channel arrangement with oscillators 1, 2, 3 connected over a single path 7, 8 to control circuits 12, 13, 14 for different transmitters. The oscillator 1 generates different frequencies, e.g. 300, 350 cycles with a transmitting key 4 in the open and closed positions respectively. The circuit 12 at the transmitter station comprises tuned transformers 15, 16 connected to two diagonal points of bridge rectifier arrangements 21, 22. On the reception of either frequency a positive voltage is produced at the other diagonal points of the bridge 21 or 22 and is applied to one of two oppositely wound windings of a relay 23 which on operation switches on the transmitter. For signal transmission-assuming, for example, that the marking frequency is 300 cycles-the positive voltage at the diagonal points of the bridge associated with the transformer 21 is much higher than that produced by the bridge 22. The grid of a valve 24 becomes more positive and the resulting increase in plate current reduces the voltage applied at an output terminal 28. The reception of the spacing frequency effectively decreases the voltage applied to the grid of the valve 24 and with the reduced plate current a relatively higher spacing voltage is applied at the terminal 28. The marking and spacing voltages derived at the terminal 28 of the circuits 12, 13, 14 may be utilized to key an associated radio transmitter. Specification 442,342, [Group XL], is referred to.

Title: Improvements in or relating to punched card handling machines
Filed: 1956-06-13
Abstract: 826,679. Statistical apparatus. SPERRY RAND CORPORATION. June 13, 1956 [June 13, 1955], No. 18333/56. Class 106 (1). Sensing apparatus for record cards comprises means for feeding the cards 51, Fig. 13, to bring the rows of data positions in succession under the sensing brushes 87, photo-electric means for detecting a card fed to sensing position and for initiating a succession of electric pulses for application to the sensing brushes, these pulses being synchronized by a magnetic disc 82 rotating in time with the card feeding rollers so as to coincide with the data positions. As the leading- edge of the card passes over the photo-cell 90 a pulse is generated and passed through gate G100 both to recording head 83 and to the sensing brushes 87 to coincide with the passing of the first row of data under the brushes. The magnetic mark recorded by the head 83 is read by head 84 and passed through gate G109 back to the recording head and also to the brushes 87 where it coincides with the second row of data. The cards are fed from a hopper 17, Fig. 3, by a knife 21 on picker arm 22. The arm is oscillated by a cam 26 and may be latched in one extreme position by a latch 28 controlled by a magnet 29. The cam shaft is driven by a belt from motor 25, the belt also passing over pulleys serving to drive the feed rollers 47, 48 for the cards. The magnetic disc 82 is fastened to the middle lower roller shaft. On emerging from the last pair of rollers the card is taken by grippers on drum 54 and carried round to be stacked on plate 62. If an error is detected in any card the lever 67 is swung into the path of the card to draw it out of the grippers and cause it to fall into the error pocket 16. The sensing brushes 87 are mounted on a cross-bar 86 of insulating material, there being eighty brushes; one for each column of the cards. All brushes are pulsed by the circulating sprocket pulse and where the pulse coincides with the registration of a brush with a card perforation, the pulse is transmitted to a contact strip under the card. In another form the picker knife is modified by the provision of a suction chamber adapted to grip the card adjacent the knife edge. A suction chamber is also provided across the width of the feed hopper adjacent the exit throat 17b. Slots are provided in the floor of the hopper so that the card is drawn downwardly and passes through the throat without jamming.
