Title: Improvements in or relating to binders and adhesives
IPC: C09J103/04
Filed: 1955-10-04
Abstract: Wood substitutes, e.g. furniture panels, are moulded from a fibrous composition prepared by mixing wood shavings or sugar cane waste, impregnated with aqueous caustic soda, with an adhesive obtained by mixing starch with a substance capable of evolving formaldehyde, such as paraformaldehyde or hexamethylenetetramine, dissolving this last-mentioned mixture in an aqueous solution of formaldehyde, caustic soda and ammonia and neutralizing the resulting solution, e.g. by adding sulphuric acid.  Excess sulphuric acid may be added as a hardener to bring the pH value of the solution to about 5. Alternatively, hardeners such as acetic acid, pyridine or monoethanolamine may be added.  The fibrous composition may also contain a synthetic resin, e.g. urea- or melamine-formaldehyde resin or polyvinyl chloride, or melamine and/or urea.ALSO:Moulded fibreboards, furniture panels, floor-coverings, shuttles, rifle butts and lavatory seats are made from a fibrous composition prepared by mixing wood shavings or sugar cane waste, impregnated with an aqeuos solution of caustic soda, with an adhesive obtained by mixing starch with a substance capable of evolving formaldehyde, such as paraformaldehyde or hexamethylene - tetramine, dissolving this last-mentioned mixture in an aqueous solution of formaldehyde, caustic soda and ammonia and neutralizing the resulting solution, e.g. by adding sulphuric acid.

Abstract: 859,099. Bending glass sheets. LIBBEYOWENS-FORD GLASS CO. Sept. 3, 1958 [Sept. 26, 1957], No. 28251/58. Class 56. In the bending of a glass sheet into conformity with a concave bending mould in which an upwardly directed face is applied to an end of the sheet to lift the end upwardly in facilitating the depositing of the sheet on the mould during bending, the force applied to the end of the sheet is maintained normal to the sheet surface during the application thereof. The mould 22, supported on a frame 18 comprising U-shaped sides 20 and end posts 19, has a centre section 23 formed with rails 29, 30 and supports 31, 32 parallel thereto joined by blocks 33 with cross struts 34, joined by hinges 25 to end sections 24 formed into rails 35 and parallel supports 36 joined by blocks 37 the end sections 24 being pivotally mounted by a rod 26 joined by links 27 to pins 28 mounted in brackets 21 on the sides 20. At the apex A of the end sections, at which the sheet 45 is supported in the open position, each rail 35 is slotted at 56 and a roller 53 is positioned therein, the roller being supported on a pin 54 between brackets 55 secured to the support 36 to be with its upper part at a tangent to the plane through the adjacent edges of the rail 35. The sheet 45 is supported at intermediate positions by fixed and movable supports 38, 39 secured to the centre section 23 and extending outwardly to engage the glass sheet over the end sections 24. Each support 38, 39 comprises a U-shaped bracket 44 with a support block 40 and locator block 41, each of refractory material, mounted on a support rod 48 secured to the rail 29 or 30, the support 38 being fixed thereto and the support 39 being mounted by a bearing 47 offset from the centre of the U so that the support tends to pivot outwardly to engage a rod 52 in the vertical position of Fig. 4.

Abstract: 902,057. Electric selective signalling systems. CONTRAVES A.G. Aug. 19, 1960 [Aug. 19, 1959], No. 28787/60. Class 40 (1). [Also in Group XIX] An arrangement for measuring a volumetric quantity and indicating its product with a variable parameter comprises means for producing pulses in accordance with the volumetric quantity and a binary counter for said pulses, outputs from the stages of the counter being connected to switches controlled in accordance with the value of the parameter, the output from the switches being commoned and connected to a product-indicating counter. The binary counter thus constitutes a frequency divider the variable division factor of which is determined by the variable parameter. As described, the arrangement is applied to indicating the total cost of liquid dispensed from a dispensing apparatus at a preset unit price, but other applications are suggested. Liquid flowing through a pipe R, Fig. 1, operates an impulse generator IG comprising a rotatable permanent magnet adapted to produce pulses in co-operating coils which pulses are fed to a binary counter or frequency divider BZ comprising conventional transistor bi-stable stages F1-F10 adapted to produce output impulses when changed from the " 0 " to " 1 " state. The " 0 " output of each stage F1-F10 is connected to a price variator OSp comprising switches S1-S10 and a unit price indicator PS. The pattern of open and closed switches S1-S10 is set in accordance with the desired unit price, and the outputs of the switches S1-S10 are connected to a common line Lp which feeds further binary frequency divider stages F11-F13, the output of the stage F13 being applied to a total cost indicating counter PZ. The " 0 " outputs of the frequency divider stages F3, F4, F7 are commoned at OSm and connected to further binary frequency divider stages F15-F18, the output of the stage F18 being connected to a total volume indicating counter MZ.

Title: Improvements in circulatory systems for the regeneration of spent solutions from thepickling of ferrous metals
IPC: C01G49/14
Filed: 1948-11-05
Abstract: <PICT:0670085/III/1> In a process involving the crystallization and recovery of iron sulphate heptahydrate from the used pickle liquor for ferrous metals and the re-use of the mother liquor, concentrated sulphuric acid is added to the used liquor during agitation thereof, and the regenerated liquor from a previous crystallization step is passed through a conduit in the used liquors so as to absorb the heat produced by the addition of the acid and to bring the regenerated liquor substantially to pickling temperature.  The amount of acid used is such as to obtain an acid concentration of 125-200 g./litre for a concentration of iron ranging from 125 to 105 g./litre as sulphate, the acid concentration being higher as the sulphate concentration is lower.  In Fig. 1, the liquor from pickling tanks B is pumped to tank 10 provided with a stirrer 29 to which 60 DEG B<\>ae sulphuric acid is added from tank 12.  The heat produced is removed by passing regenerated liquor from tank 22 through coil 14, whence it passes via pipe 24 to regenerated liquor tank 18 or to the first of the pickling tanks.  The solution then passes to tank 32 provided with stirrer 29 wherein it is cooled by the passage of water through coil 35, the water passing to outlet cock 36a or via cock 37a to regenerated liquor tank 18.  The liquor now containing suspended ferrous sulphate heptahydrate passes to settling tank 16 from which the mother liquor is decanted at 17 into tank 18 whence it is pumped to tank 22.  A drain plug 30 is provided in the settling tank.  If desired, tank 10 only may be employed, in which case after the acid addition, first the solution from tank 22, then water through pipe 39, is passed through coil 14, the water escaping through pipe 40. Another Figure is provided illustrating the use of single heat exchange tank.  Conversely, any desired number of such tanks may be employed.  The Specification as open to inspection under Sect. 91, discloses the use of a centrifugal filter in place of a settling tank. This subject-matter does not appear in the Specification as accepted.
