Title: Improvements in and relating to the treatment of waste acid pickle liquor
Inventor: BOX PETER LUCAS
IPC: C01C1/24
Filed: 1963-06-29
Abstract: Iron hydroxides and ammonium salts are obtained by absorption of ammonia from coke oven gas in waste acid pickle liquor followed by mixing of the acid liquor with ammoniacal, liquors at a temperature between 50 DEG  and 150 DEG  C. under a pressure sufficient to prevent the boiling thereof.  Ferrous hydroxide is separated from the liquors, which are then aerated to precipitate any remaining iron, prior to crystallization <PICT:1002773/C1/1> of ammonium salts therefrom.  The waste acid pickle liquor may comprise hydrochloric, nitric, phosphoric or sulphuric acid. The ammoniacal liquors may be concentrated ammoniacal liquor condensate from a coke oven plant. Pyridine liberated in the process may be recovered.  As shown, coke oven gas from line 60 is scrubbed with waste acid pickle liquors from line 56 in absorber 54, make-up acid entering by line 58.  The liquors from absorber 54 are stored in vessel 12 before passage to reactor 15.  Dilute ammoniacal liquor from a coke oven plant is concentrated in plant 46, stored in vessel 42, and added to the reactor through line 44. Make-up ammonia may be added from vessel 11 via pipe 13.  The reaction mixture is centrifugal in plant 22, ferrous hydroxide being collected through line 23 and the liquors being oxidized in plant 25 to precipitate ferric hydroxide.  The latter is separated by centrifuge 28, and the liquors therefrom are passed to crystallizer 31.  Pyridine liberated in reactor 15 is condensed in condenser 20 and that liberated in the oxidizer 25 is transferred thereto via line 62.  Liquors from centrifuge 22 may be recycled to vessel 12 or to line 56.

Abstract: Fibrous material in the form of a sheet, web, fleece or the like contains regenerated cellulose fibres, in the preparation of which at least one substance activating a fibre-fibre bond has been added. This substance may confer acid, basic, anionic, cationic or contact-adhesive properties, may be a thermoplast or elastomer, and may swell strongly in water.  Examples are ethylene diamine, polyethylene diamine, polyvalent acids or acid salts, polyacrylic acid, cellulose-glycollic acid, alginic acid, polyethyleneimine, condensates of formaldehyde with urea, guanidine, dicyandiamide or melamine, basic cellulose derivatives, natural or synthetic rubber, polymers and copolymers of acrylate esters and acrylamide, cellulose or starch derivatives, polyvinyl ethers, polyvinyl alcohols or mucilages.  Hardeners such as formaldehyde or compounds which split off formaldehyde may be added.  The activating substance may be added to the solution from which the fibre is spun, and the fibres are then cut to staple length, formed into a suspension and a sheet, web or fleece formed therefrom.  Bonding occurs between the fibres containing the activating substances and fibres not containing it. The latter may be of regenerated or natural cellulose, wool, silk, inorganic fibres, polyamides, polyesters, polyacrylic compounds or polyvinyl compounds.  A precipitating agent, e.g. aluminium sulphate may also be present.  Alternatively there may be used: fibres of two different kinds containing different activating agents, e.g. oppositely charged or able to form bonds through secondary valencies; fibres of one kind only bonded by purely physical forces; or fibres of one kind bonded by a bridge-forming additive, e.g. a polyvalent base such as polyethylene diamine or ethylene diamine with acid-reacting fibres or a polyvalent acid with basic fibres.

Title: Improvements in and relating to feeding mechanisms for sewing machines
IPC: D05B27/08
Filed: 1929-08-30
Abstract: 318,589. Union Speicial Machine Co., (Assignees of Zeier, F. F.). Sept. 6, 1928, [Convention date]. Feed by dogs.-A differential feeding mechanism for sewing-machines including main and auxiliary feed dogs, has the auxiliary dog positively connected to its operating member without sliding adjustments, and by a flexible connection. The throw of the dogs may be adjusted. The main feed dog 7 is carried by a feed bar 9 having lugs at its end to carry the shaft 16 which connects it to the feed rocker 11 pivoted at 12. The rocker is operated by a rod 32 secured to the shaft 16, Fig. 2, and pivoted at 34 to an arm 35 on a crank 36 of the main shaft 3. A screw 38 enables the length of the arm 35 to be adjusted to vary the throw of the dogs. The auxiliary dog 8 is carried by a bar 18 housed in a recess in the bar 9 and connected by screws 20, 21 and a flexible plate 19 to one arm 17 of a bell crank lever pivoting on the shaft 16. The auxiliary dog therefore receives its throw motion from the shaft 16. The differential throw is imparted to it by the rocking movements of the bell crank lever on the shaft 16. The other arm 17<a> of this lever is pivoted at 22 to a link 23 connected to a crank 24 on an arm 25 pivoted at 26 to a fixed bracket 27. A coil spring encircles the shaft 26 and constantly tends to rotate the shaft in a counterclockwise direction. As the feed rocker 11 is oscillated therefore, the main dog 7 is moved horizontally thereby while the auxiliary dog 8 moves through the throw due to the rocker plus the additional throw due to the rocking of the bell crank lever 17, 17<a>. The extent of this additional throw is determined by a lever 59 with a pin 64 working over a graduated scale on the bracket 62. The lever 59 has a lug 61 engaging a lug 58 on a collar fixed to the shaft 26. By moving the lever, the shaft 26 is turned to vary the set position of the crank 24, so varying the extent of rocking of the bell crank 17. 17a. The up-and-down motion of the dogs is imparted by an extension 41 on the bar 9 pivoted to an eccentric strap 44 on the main shaft 3. Between the strap 44 and the eccentric 40, a floating sleeve 43 is provided, kept from axial displacement by a screw 50 engaging a circumferential slot in the sleeve. A lubricating pad 54 in the strap supplies lubricant to the sleeve.

Title: Electrical switching circuits
Inventor: SAUNDERS RONALD
IPC: H03K19/086
Filed: 1965-06-24
Abstract: 1,071,362. Switching circuits. INTERNATIONAL BUSINESS MACHINES CORPORATION. June 24, 1965, No. 26712/65. Heading H3T. A switching circuit comprises a constantcurrent generator and a switched load in parallel, in series with a drain circuit across a supply, the current taken by the drain being controllable so that when the load is switched on and the drain is switched to its higher conductance state, the latter takes more current than the generator can supply and the excess will be drawn through the load, but otherwise the drain will take the whole of the generator current and the load will not be energized. In Fig. 2 the generator and drain are transistors T1 and T2 respectively, the load comprising drive lines 7, 8 of a computer store selectively connectable by transistors T6, T7. In the rest condition T3 is saturated, biasing T5 to conduct at a level such that the base of T2 is slightly more positive than its emitter; T2 then takes all its current through T1, both T6 and T7 being biased off. To drive a current through the load, the appropriate transistor T6 or T7 is turned on by a signal on its base and T3 is similarly turned off. The current through T5 is now determined by the conduction of T4 and this is adjusted so that the base potential of T2 is raised and T2 takes more current than T1 can supply, the excess flowing through the load 7 or 8. The value of the load current can be controlled by the value of input pulses at 10. In a modification (Fig. 3, not shown), T1 is replaced by a resistor (11) whose junction with T2 is connected via a diode (12) to a voltage lower than + V1. The switching circuit T3-T5 is replaced by a single transistor (T9) and the control signal passes through its emitter-collector path. This transistor is caused to conduct by removing the control signal from its emitter; the base of T2 (T8) is clamped to earth by a diode and T2 (T8) then conducts more heavily.
