Patent GB-464905-A (GB)
Title: Improvements in or relating to processes for manufacturing artificial or reconstructed leather
IPC: C08L89/06
Filed: 1936-10-31
Abstract: A process for making artificial and reconstructed leather from admixtures of disintegrated scraps and cuttings of leather or hides or both and aqueous rubber dispersions is characterized in that the admixtures contain the insoluble precipitate formed by the interaction in an aqueous medium of a water-soluble zincate and magnesium bicarbonate.  It is stated that the precipitate is a coagulant for rubber dispersions and an accelerator of vulcanization. The zincate may be sodium zincate.  The precipitate is presumed to be an intimate mixture of zinc oxide and magnesium oxide carbonated by a molecule of carbon dioxide, thus ZnO.MgO.CO2; its composition may be modified.  Thus a precipitate may be formed by partially decomposing an aqueous zincate solution by means of carbon dioxide, keeping the zinc oxide thus formed in suspension by mechanical agitation, and mixing this suspension with magnesium bicarbonate; this method gives a higher proportion of zinc oxide than the simple mixing method.  A precipitate rich in magnesium carbonate can be obtained by using an alkaline solution of zincate and excess of magnesium bicarbonate. The precipitate may be formed in situ in the rubber dispersion by adding to the dispersion first an aqueous zincate solution and then an aqueous magnesium bicarbonate solution; or the two solutions can be added at the same time.  In an example an artificial leather comprises, inter alia, 290 parts by weight of chrome tanned hide cuttings, 100 parts by weight of rubber in the form of normal latex and 19 parts by weight of a 5 per cent aqueous paste of the precipitate.  The leather mix may contain also reinforcing ingredients such as oxides of titanium, silicon and aluminium, and carbon black, as described in Specifications 422,027 and 422,028.

Abstract: 1530055 Automatic control of PL INTERNATIONAL BUSINESS MACHINES CORP 18 July 1977 [2 Sept 1976] 30078/77 Heading G3R The Ph of a liquid in a processing tank is automatically controlled by a system in which, when the Ph detected by a known device 20 drops below a predetermined level, a finite quantity of a concentrate from a tank 25 is added at 27A immediately on to measuring electrodes in the device 20 and a timer is started which prevents a further addition for a predetermined time, long enough for mixing to occur. The object is to overcome the "hysterisis" of the device, which requires an increase in Ph of 0À2 to reset; in the present arrangement the "dose" resets the device but increases the general Ph by a smaller amount, e.g. 0À05. The device 20 is situated adjacent the intake of a pump which circulates the liquid through spraying heads beneath which glass plates are passed on which electrodes are formed by etching. The amount of concentrate is determined by timer control of a valve 26, and a further timer inhibits the system for a period after initial start-up.

Abstract: 1,090,553. Injection moulding. DOW CHEMICAL CO. July 15, 1965 [July 23, 1964], No. 30118/65. Heading B5A. A thermoplastic article having high multidirectional molecular orientation is moulded in a mould, one element of which is rotatable, means being provided for sensing when the cavity is filled, and means for terminating the rotation a predetermined time after the mould is filled or after a predetermined number of revolutions. The article may be produced in injection moulding apparatus similar to that in Specification 1,067,100, or by impact moulding (Fig. 3, not shown). The means for sensing when the mould is full may comprise a glass-insulated electrode (58) arranged flush with the mould surface, and connected to a source of power sufficient to cause sparking between the electrode and one of the mould elements. The thermoplastic material quenches the sparking and results in a signal being passed to control means to start the counting. After a predetermined number of revolutions the rotating mould element is stopped. In a preferred embodiment (Figs. 4, 5, not shown) the sensing means comprises a thermistor (90). In a modification a time delay relay terminates the rotation a predetermined time after the mould is filled.
