Title: Improved fabrics of cellulose acetate
IPC: D06M13/525
Filed: 1963-04-19
Abstract: Woven or knitted fabrics consisting of or containing cellulose acetate threads or yarns having drip-dry properties and good dimensional stability are produced by a process comprising the steps of (a) washing out any size from the fabric, e.g. with soap or a condensation product of ethylene oxide and lauryl alcohol, removing excess desizing liquid and drying, (b) passing the fabric, if woven, over a stenter with overfeed and light steaming, (c) dyeing or printing, e.g. with solid fast acid or dispersed dye, washing, drying, applying a softening finish, e.g. a condensation product of a long chain fatty acid with ethylene oxide, further drying with overfeed and light steaming, (d) steam decatisation and (e) where necessary breaking, the process steps being carried out in the substantial absence of any tensile force on the fabric, and the fabric being pebbled before or after step (a).  The pebbling may be carried out on one or both surfaces of the fabric and may be effected at a temperature of 80 DEG -150 DEG C. and under a pressure of about 6 tons for a calendar having a 150 cm bed.  Fabrics having a special appearance may be produced by treating fabrics having in the warp or in the weft or in both the warp and the weft yarns of irregular count.  Yarns in which the slubs are situated at irregular intervals may be used in the production of the fabrics.

IPC: G11B20/00
Filed: 1968-04-01
Abstract: 1,208,921. Automatic exchange systems. COGNITRONICS CORP. 1 April, 1968 [18 May, 1967], No. 15633/68. Headings H4K and H4R. A speaking machine is adapted to simultaneously supply a plurality of different spoken messages to a corresponding plurality of output lines in accordance with coded representations of the message. The apparatus shown is adapted to convert coded signals (which may represent answers from a computer) into their verbal equivalents and transmit them to appropriate telephone subscribers. The subscribers are equipped with touch-tone dialling facilities by means of which they can send coded enquiries relating to metering rates, account or other inventory information. The answers are stored in verbal form on a storage drum 30 which is of the photo-electric type, but may be of the magnetic type, each possible phrase or word is stored on a different track associated with a different read amplifier MA0 to MA31. A phrase fills a complete track, while a word is repeated at three equally spaced intervals around a track. The commencement of each word and the start of a phrase are marked by pulses on a flag track associated with a further read amplifier 36. The output of this amplifier passes to a circuit 37 which distinguishes between a word start pulse and a phrase start pulse by detecting its duration and energizes one of a pair of lines 38 and 39 leading to the computer. The module shown to the right of the Figure can deal with ten simultaneous calls and has ten outputs, one each from output amplifiers SAFi-1 to SAF-10. Each output amplifier has associated with it a five bit flip-flop register 51-60 and a comparator 71-80. When the computer receives a signal on line 38 or 39 as previously described, it clears some or all of the registers 51-60 and enters into them the binary code designations of the next words or phrases to be transmitted one to each line. All tracks on the drum are read out simultaneously and scanned rapidly by a counter 42 and a diode AND gate matrix 43 feeding an OR gate 45 to provide a multiplex verbal message on a line 46. This message is applied simultaneously to the amplifiers SAF-1 to SAF-10, but each amplifier is only opened during the time slot associated with the message track specified in the register 51 to 60 associated with that amplifier. The gating signal for the amplifier SAF-1 for example is provided by coincidence circuit 71 when the count of the counter 42 coincides with the code set in the register 51. A maintenance and check unit enables a coded representation to be inserted into a register under manual control.

Abstract: 805,125. Stapling machines. CARSTAIRS, L. S. May 23, 1956 [June 1, 1955], No. 15712/55. Class 89(3) [Also in Group XXIV] In a stapling appliance wherein staples are ejected by the release of a compression spring, a control device is provided which when operated causes an electric motor to compress the spring, the spring being automatically released when compressed through a prescribed distance. In the exemplified embodiment, a stapling machine similar to that described in Specifications 767,273 and 767,274 is actuated by an electric motor 18. The motor 18 drives a worm 25A engaging a worm wheel 25 freely mounted on a hub 34. The worm wheel 25 and hub 34 are connectable by a roller key clutch of which the roller key 36 is normally held against a spring in a declutched position by a lever 42 engaging a handle 38 projecting from the roller key. To drive a staple a button 48 is depressed causing the lever 42 to release the handle 38 allowing the key 36 to spring into a position wherein it clutches the worm wheel 25 to the hub 34 so that the hub rotates. An eccentric pin 27 carried by the hub 34 rocks a lever 30 about a pivot 31 and a spring loaded pivoted pawl 16 at the upper end of the lever 30 retracts a hammer block 14 against a spring 15 until the pawl 16 is released by striking a pin 17 to allow the block 14 to return under the action of the spring 15 to drive a staple. The mechanism continues to operate whilst the button 48 and a trigger 20 of an electric switch 19A for the motor remain depressed. In the construction described in the Provisional Specification, the pawl 16 and the manual control for the roller key clutch are differently arranged.

IPC: C01C1/244
Filed: 1951-07-09
Abstract: Ammoniacal liquor, particularly concentrated liquor resulting from steam stripping of gas-works ammoniacal liquor is treated with copperas (FeSO4.7H2O) in solid form or as a slurry in water, in such a quantity that the total ammonia (free and combined) represents up to 10 per cent, excess by weight of that theoretically required to react with the copperas, removing the precipitated iron oxide, mixing the filtrate with an additional amount of ammoniacal liquor, approximately 15 per cent of that originally employed and removing further precipitated iron oxide.  The filtrate, free from iron, may be stripped of excess ammonia by steam and the ammonium sulphate concentrated and crystallized.  The precipitated iron oxide may be mixed with a filler such as peat or sawdust or with burnt oxide or solvent extracted spent oxide and employed for coal gas purification. The reaction may be carried out at 60-100 DEG C. as a continuous or batch process; when a slurry of copperas is employed, this may be made up with part of the first or final stage filtrate.

Abstract: 497,035. Protective cut-out arrangements. STANDARD TELEPHONES & CABLES, Ltd. (Piece, R.) June 11, 1937, No. 16277. [Class 38 (v)] [Also in Groups XL and XXXV] A radio transmitter has a safety air gap associated with the aerial for protection against lightning discharges, and a switch is provided which in response to an increase in radio-frequency current in the earth lead when the spark gap flashes over, causes the discontinuance of the radio frequency feed to the aerial, and removes the high-tension supply from the transmitter valves. The aerial feed coil T R and the series condenser C are shunted by a gap S G which discharges a lightning flash direct to the earth lead L. When this occurs, the aerial and the earth lead L may carry excessive radio-frequency current which tends to maintain the spark-gap SG conductive. A coil coupled to the earth lead L and forming the secondary coil of a radio-frequency current transformer CT, is connected as one diagonal of a rectifier bridge R, the other diagonal being connected to a relay A, which is rendered operative by the rectified radio-frequency current. A further relay B is thus operated to disconnect the feed from the aerial, and to operate a counter G. A further contact may control a no-volt coil BBC on all oil switch. The relays restore to normal position when the are across the gap SG is extinguished. The screen. S of the transformer TR may be connected to the earth lead L.

[Class 137] [Also in Group XXXIII] In supplying air under pressure to land vehicles, ships, and aeroplanes, wherein a hood 12 is provided and is sealed by an inflatable tube 13, valve mechanism for controlling the air supply to this tube and to the cabin is so arranged that in one position the air is cut off and the tube deflated, in another, the tube is still deflated but air is supplied under pressure to the cabin, and, in a third position, the tube is inflated and air pressure is maintained in the cabin. Air, heated if required, is supplied under pressure from a source 15, and passes by pipe 16 to the interior of a rotary valve 17 which directs it either to exhaust 22, or, by pipe 23, to the interior of the cabin. A part of the pressure air is taken by a pipe 26 to another rotary valve 28 connected by a gear chain 29 to valve 17 and operated by a handle 30. In the position shown, pressure air passes to. exhaust and ventilation is effected by air passing between the deflated tube 13 and the hood. By moving the handle 30 through 90 degrees air passes through ports 20 to pipe 23 and the cabin while valve 28 connects ports 27, 31, so that air from behind choke 24 passes to inflate tube 13 and seal cabin. By turning back handle 30, the pressure supply from port 20 can be cut off without exhausting the tube through passage 32, the pressure being maintained in the cabin, and by turning the handle further, the tube may be exhausted to pipe 34 while air is still being supplied to the cabin. In a modification, the two valves may be mounted on the same spindle.
