Title: Imparting crease-resistance and shrinkage control to cellulosic textile materials
IPC: D06M15/423
Filed: 1950-02-07
Abstract: Textile fabrics consisting of natural cellulose, regenerated cellulose or mixtures thereof with up to 50 per cent of cellulose acetate are impregnated with an aqueous solution containing 1-7 per cent of monomethylol dimethyl hydantoin or dimethyl hydantoin formaldehyde, together with dimethylol urea and a water-soluble non-volatile acid in such amount as to give the solution a pH from 2 to 2.5, and the surplus liquid is removed from the fabric, which is then dried at 180 DEG  to 240 DEG  F., baked at 212 DEG  to 310 DEG F., and finally neutralized and washed.  The dimethylol urea may be used in amounts from 3-10 per cent of the weight of the material (100 per cent pick-up).  Suitable acids are oxalic, lactic, tartaric, citric, boric and phosphoric acid.  If desired, the impregnating solution may contain a small amount of sodium sulphate.  The drying of the impregnated fabric may be carried out without tension, and the curing time may be from 2 to 5 minutes.  After curing, the fabric may be neutralized with, for example, soda ash, soaped, rinsed and dried. If desired, wetting agents may be added to the bath to improve the hand of the material, or starches, gums, glues, gelatines, modified starches, or solutions or dispersions of polyvinyl alcohol may be used to give a stiffened effect.  In an example a series of aqueous compositions comprising, per litre, 20-30 g. monomethylol dimethyl hydantoin, 40-80 g. dimethylol urea, 4 g. of anhydrous sodium sulphate, 1 g. wetting agent and varying amounts of oxalic and/or lactic acid are prepared, and used to impregnate spun rayon fabric. The fabrics are squeezed to 100 per cent pick-up, dried without tension at 180 DEG  F. and baked for 3 minutes at 300-310 DEG  F. Specification 449,243 is referred to.

Title: Apparatus for collection of dirt particles
IPC: B01D46/04
Filed: 1973-01-23
Abstract: 1424863 Fluid filter H G G LYNFIELD (Aerodyne Development Corp) 23 Jan 1973 3454/73 Headings BID and BIT An air or liquid filter comprises at least one pair of concentric filter bags or sleeves 60, 64 through which fluid is filtered in series, the upstream bag 60 being periodically cleaned by delivering reverse flow fluid directly into the space between the bags which flexes said upstream bag. Fig. 9 shows a series of bag pairs arranged in rows in a common housing. Dirty air flows from inlet 65 to the interiors of open-ended inner bags 60 and dust is discharged at 68. Reverse flow blower 70 may draw air from filtrate outlet 79 or atmosphere and delivers it via respective solenoid valves 76 to manifolds defined between tube plates 58, 59, each manifold communicating with spaces between the bags of different rows. The filtration may proceed under suction at outlet 79 or delivery pressure at inlet 65, and in the latter case central part 57 of the housing could be omitted. In Figs. 1, 2 (not shown) construction is similar, but dirty air enters the apparatus via the dust hopper (10b), and the inner, upstream bag is closed at the top. The valve (31) controlling supply of reverse flow air is operated by a solenoid or ram. Fig. 3 (not shown) involves a similar filter bag arrangement, but a single reversible blower and two one-way valves draw filtered air from the outlet and deliver reverse flow air to between the bags. Several such bag arrangements could be located in one housing but with individual blowers, so that reverse flow air from one passes to others on forward flow. Figs. 6, 7, (not shown) illustrate pluralities of bag pairs in one housing enabling some pairs to filter while others are cleaned. In Fig. 7 filtration is under suction and reverse flow is created by opening valves (31) to atmosphere. In all above embodiments filtering flow is outwards and both bags are of flexible woven, felted or knitted fabric, but in Fig. 8 (not shown) flow is inwards and the downstream bag is of rigid ceramic, sintered metal or wire mesh and only the outer bag is flexible. In all cases the upstream or downstream bag may be the more pervious of the two, but preferably the upstream bag retains most of the dirt. Bags may be cylindrical or flattened. To prevent the inner bag collapsing completely during reverse flow, the two bags may be stitched together along seams 92 (Fig. 16) or the inner bag may be stitched to longitudinal metal rods or taut cords (Figs. 13, 14, not shown). Fig. 11 (not shown) illustrates an electric pulse-generating device which could improve bag-cleaning in any embodiment by repeatedly opening and closing a reverse flow valve or starting and stopping or reversing a reverse flow blower.

Abstract: 1453323 Automatic electric control TOYODA-KOKI KK 28 Jan 1974 [21 Feb 1973] 03785/74 Heading G3N A monitoring arrangement for detecting faulty operation in a sequence of machine operations consisting of at least one machine cycle, includes a memory store for operations within the cycle to provide test instructions and control instructions, a timer for timing a sequence to see whether a predetermined time has been exceeded, a search process responsive to the existence of excess time for investigating the cycle information stored in the memory to produce a faulty cycle number signal and means responsive to said signal to select a diagnosis programme to find and indicate the cause of the faulty operation. As shown the sequence controller 10 includes a memory 11 which stores all the data relating to each cycle of the sequence of operations and connects through logical processing unit 12 to send control signals via circuit 15 to the machines under its control and to receive state signals, shown by the contacts, as input signals. A time clock 13 ensures that output and test instructions are sent out correctly. A general purpose mini-computer 20 is connected to the sequence controller through interface 16. Figure 2 shows a typical set-up where each sequence controller 10 controls a plurality of machines and an automatic typewriter 21 is provided in addition to indicator 22 to give fault indication data. The output signal control circuit 15 is provided with latching relay indicators and timers which are used for each cycle during the controlled operation and can be interrogated when fault finding. Thus a timer is set at the start of each cycle and should time out shortly after the cycle is completed if it times out before the cycle is completed then the operation is recognised as faulty and the relays are interrogated to identify which cycle is giving the faulty operation. The cycle number is sent to the computer which searches the operations within the cycle in accordance with a predetermined diagnostic programme to identify the faulty operation and indicates this accordingly. The circuitry is arranged to respond so that a fault signal is only sent once to the computer. A flow chart of a typical diagnostic programme is described, Figure 6, (not shown).
