Abstract: 1,222,516. Moulding foam material. DUNLOP CO. Ltd. 3 July, 1968 [6 July, 1967], No. 31240/67. Heading B5A. A method of moulding a porous foam material comprises positioning a sheet of porous polyurethane foam material between an air impermeable elastomeric diaphragm and a heated shaping mould and creating a pressure differential on opposite sides of the diaphragm to cause the diaphragm to move the foam material into contact with the shaping mould and to at least partially compress the foam. The pressure differential is created by applying a vacuum between the diaphragm and the mould and can be augmented by applying fluid under pressure to the diaphragm or it can be wholly hydraulic. The mould is heated to between 150-300‹ C. The foam may be either polyether or polyester polyurethane. The foam material may have a flock-coated surface, e.g. using nylon flock and it may be reticulated. Articles made are upholstery, shoe uppers, luggage handbags, soft toys and wearing apparel, especially simulated animal fur gloves.

Abstract: 958,833. Evaporators; distilling water. RICHARDSONS WESTGARTH & CO. Ltd. Sept. 9, 1960 [Sept. 14, 1959], No. 31246/59. Heading B1B. In a multi-stage flash-type evaporator, suitable for distilling sea-water, comprising a vessel divided by internal walls 8 into a number, e.g. twenty or more, separate chambers 7 each having a tube nest 11 for heating the liquid and a flash-section 7b, at least part of each internal wall extends in a plane other than the vertical. In the horizontal evaporator shown in Figs. I and 2, the upper part 8a of each dividing wall is inclined at an angle relative to the bottom of the evaporator. In Figs. 9 and 10, the chambers are arranged one above the other and each of the internal walls 8 is contained entirely in a horizontal plane, and is provided with a reinforcing frame 12. The tube nests of the heater-sections are connected in series. The flash-sections 7b are also connected in series by apertures 9. The first heater-section is in the same chamber 7 as the last flash-section ; and the last heater-section is in the same chamber as the first flash-chamber. In operation, seawater passes successively through all the tube nests wherein it is heated by vapour flashed off in each of the flash-sections. Before the preheated brine, leaving the last tube nest, is transferred to the first flash-section, it is heated to a higher temperature by an auxiliary source of heat in a so-called heat-input section. This heat-input section may be outside the evaporator vessel, or it may be housed in the last heater-section of the evaporator vessel. The hot brine then passes successively through all the flash-sections, in each of which vaporization takes place. The vapour flashed off in each chamber condenses on the external surfaces of the tubes 11 ; and the resultant distillate is collected in a tray 17 arranged below each tube nest. The distillate may be withdrawn from each tray individually ; alternatively, the trays may be connected in series and the distillate withdrawn from a single point. In Fig. 14, each chamber 7 is divided into three sections by two reinforcing frames, the middle section 7c being used for separating any brine particles which may be entrained in the vapour.

Abstract: 1,273,418. Making filter elements. PHILIP MORRIS Inc. 20 June, 1969 [24 July, 1968], No. 31438/69. Headings B1D and BIT. [Also in Divisions A2, B5 and B6] Continuous filter rod particularly for cigarette filters but suitable also for filtering liquid or other gaseous media is produced by extruding a thermoplastic material such as polyethylene through a tubular die 28 to form a tube of greater diameter than the intended final diameter, advancing a fibrous tow 14 of filter material through a nozzle 38 so that it does not come immediately into contact with the hot extrudate, and subsequently contracting the tube in a portal gland 42 at the entrance to a cooling chamber 40. The tow, which may be of cellulose acetate, a polyalkene, polyethylene or paper, is treated with a plasticizer, e.g. triacetin, and may contain filtrant or flavourant particles, e.g. charcoal. It is partially compressed in a horn 26 to a cylindrical form of slightly larger diameter than the final internal diameter of the tube so as to be radially compressed as the tube is finally sized, the tow being bonded to the tube either as a result of the inner wall of the latter being still plastic, or by the plasticizer in the tow. The cooling chamber 40, which contains water and a succession of sizing plates 48-58 to provide progressive cooling and hardening of the tube, is followed by a puller unit 64 and cutter (not shown). The tube, which is kept in contact with the sizing plate apertures by the provision of vacuum in the chamber 40, may have a cylindrical or polygonal outer surface, or a surface with longitudinal flutings.

Title: Improvements in or relating to preparation of iron-aluminium alloys
IPC: C22C33/04
Filed: 1956-10-17
Abstract: In a process for producing a ductile iron-aluminium alloy, e.g containing 6-18 per cent aluminium, in air at atmospheric pressure the ingredients of the alloy are thoroughly deoxidized and maintained in that condition until the alloy has solidified. Electrolytic iron may be melted in a rammed magnesia crucible by induction heating, deoxidized with 0.1 per cent of aluminium and 0.5 per cent of manganese added as such or as ferro-alloys, and finally deoxidized with calcium which may be plunged into the melt by means of an iron rod.  In place of calcium a aluminium-calcium alloy or magnesium may be used.  Aluminium is deoxidized with about 0.1 per cent of calcium and degassed by introducing chlorine through a refractory tube.  The dross is then skimmed off.  Flourspar is then added to the molten iron to form a slag and the aluminium is poured through the slag. The molten alloy is vigorously stirred and allowed to settle so that the slag may be removed.  Finally the alloy is poured at about 2900 DEG F. into cast iron moulds which have been given a wash of chlorinated pitch or exposed to carbon tetrachloride vapour.

Abstract: 1,153,891. Cathode-ray tube displays. ELECTRONIC & X-RAY APPLICATIONS Ltd. 21 Oct., 1966 [24 July, 1965], No. 31656/65. Heading H4T. In a cathode-ray tube display variations of the magnitudes of some input signals are displayed against a time base scale, e.g. traces 65, 66 (Fig. 4), whilst the magnitudes of other signals are displayed as traces 63, 70 against fixed scales 62, 69. The traces 65, 66 may be produced by the outputs of different electro-cardiographs and traces 63, 70 may indicate the heart rate of the respective patients but signals indicative of other factors may alternatively be displayed. The display is produced by the arrangement of Fig. 1, which utilizes switching circuits 11 ... 18, each comprising a pair of switches simultaneously operated by pulses from a source 30 which switches on the circuits 11 ... 18 successively and cyclically each for a period of 140 Ás at 60 Ás intervals. The outputs of the left-hand switch of each pair, e.g. T3, are connected via conductor 8 and amplifier 4 to the horizontal deflection plates 2 of the display tube and the right-hand outputs, e.g. T4, are connected via conductor 9 and amplifier 5 to the vertical deflection plates 3, 10 so that as source 30 cycles through its switching sequence the horizontal and vertical positions of the beam of tube 1 are determined respectively by the inputs to the left and right-hand switches, e.g. T1, T2. In the case of circuits 11 and 15 the left-hand switch inputs comprise the output of a time base 32 and the right-hand switch inputs comprise the outputs of electro-cardiograph amplifiers 47 and 48 respectively, the output of 48 including a fixed bias so that the respective vertically spaced traces 65, 66 are produced. For circuits 12 and 16 the left-hand switch inputs are derived from potentiometers 41, 44 the - V potential source to which includes a small A.C. component so that a, horizontally elongated trace such as 63 is produced with a similar trace if desired on the right-hand side of the display instead of the display shown. The vertical position of line(s) 63 is then determined by cardiotachometers 49, 50 which supply the inputs of the right-hand switches in 12 and 16. Circuits 13, 14 and 17, 18 are utilized to produce upper and lower limit markers such as 68, 67 the left-hand switch inputs from potentiometers 42, 43 and 45, 46 determining the horizontal position of the traces and the right-hand switch inputs from potentiometers 51, 52 and 53, 54 determining the vertical positions. If desired, one of the latter displays may take the form shown at the right-hand side of Fig. 4 in which the heart rate output of the tachometer is indicated by the length of a vertical line 71 with a desired rate value indicated by horizontal trace 70. A circuit which operates an alarm when the heart rate departs from pre-set maximum or minimum values and which rates may be displayed is described with reference to Fig. 5 (not shown).
