Title: Method of bonding a face fabric to a fusible interlining material
Inventor: GORDON BRUCE ERNEST
IPC: A41H43/04
Filed: 1967-03-22
Abstract: 1,217,333. Laminated fabric. STAFLEX INTERNATIONAL Ltd. 19 March, 1968 [22 March, 1967], No. 13558/76. Heading B5N. A method of bonding a face fabric to a fusible interlining material having a coating of a heat softenable resin on one surface comprises positioning an assembly of a piece of face fabric and a piece of fusible interlining material in superimposed relation between a platen 1 and a flexible non-porous membrane- 5, and applying pressure to the assembly by reducing the pressure in the space between the membrane and the platen, heat being supplied to the assembly to soften the resin either before, or before and during, the application of pressure, the pressure being sufficient to cause the resin to flow and integrate with the fibres of the face fabric. In the apparatus shown for performing the method, the membrane 5<SP>1</SP> is supported by a peripheral frame 61 carried by a tray 4<SP>1</SP> which is one of a pair of trays 4, 4<SP>1</SP> horizontally movable in turn to a pressing station between the platen 1 and a clamp frame 2. When the membrane 5<SP>1</SP> with the assembly to be bonded placed thereon reaches the pressing station the clamp frame 2 is raised to press the frame 6<SP>1</SP> against a sealing member 11 of the platen 1 the platen being heated. Air is then withdrawn via galleries 9 and holes 10 to hold the assembly against the platen 1 whilst the resin softens. After softening, further air is withdrawn to cause the assembly to bond. Subsequently the air is reintroduced, the clamp frame 2 lowered and the bonded assembly removed from the membrane 5<SP>1</SP>. In an alternative embodiment the positions of the platen 1 and clamp frame 2 are reversed in which case the assembly to be bonded is positioned on a sheet of porous material carried by a lower part of the frame 6<SP>1</SP> before an upper part of this frame which carries the membrane 51 is placed in position. The heating of the assembly may be effected by the support being heated by steam, oil or electrical elements, or by flexible electrically heated "blanket" between the membrane and the assembly, or by an electrically heated membrane, or by radiant heaters. The fusible interlining may be a woven, knitted, or non-woven fabric e.g. a fabric of woven cotton, or cotton and rayon threads, the resin may be a vinyl chloride/vinyl acetate copolymer applied in a pattern of dots, and the face fabric may be a 55% polyethylene terephthalate fibre/45% wool mixture or a 3-ply mohair, or a worsted fabric, or a pile fabric, in which latter case the platen is in the form of a needle board. The platen may be shaped to give a shaped product.

Filed: 1974-03-29
Abstract: 1454358 Testing batteries FORD MOTOR CO Ltd 29 March 1974 [12 April 1973] 13940/74 Heading G1U In a method of testing a lead-acid battery, if the charging current necessary to raise the battery voltage to a reference value is too low the battery is judged to be defective. Preferably this step is preceded by a discharge step in which, if the fall in the battery voltage resulting from its discharge through a standard load (0.03 ohms) is sufficiently small, the battery is judged to be good, and the charging step - above - is only performed when the discharging step produces a large fall in the battery voltage. The ideal sequence of tests, according to the Specification, is as follows (see Fig. 6):- (a)an open circuit voltage test - if the open circuit voltage is too low (e.g. 10.5v for a 12v lead/acid battery) the battery is judged to be defective and is discarded, (b)a discharge test as above - if the fall in battery voltage is sufficiently small the battery is accepted as being serviceable, and (c)a charge test as above - which is only performed if the battery is not judged to be serviceable by the discharge test and which judges the battery to be defective or serviceable in accordance with the size of the charging current necessary to raise the battery voltage to a reference level. In other words, even though a discharged battery may not pass the discharge test, it may still be judged to be sufficiently serviceable not to be discarded, by the charge test. Other possible test sequences are described.
