IPC: B29C43/00
Filed: 1969-02-18
Abstract: 1291111 Injection moulding machines IMPERIAL CHEMICAL INDUSTRIES Ltd 26 Jan 1970 [18 Feb 1969] 8714/69 Heading B5A Material is injected into a mould from two separate sources 1, 2 via separate bores 3, 4 which converge into a single sprue 6, a shuttle valve 9 being adapted to slide across the paths 3, 4 of the materials so as to open and close the two bores and the position of the shuttle 9 is determined by the relative pressures exerted on the shuttle by the two materials. Thus the shuttle 9 has cut-away portions 10, 11 acted on by the material in the channels 4, 3 respectively. A rotary shut-off tap 5 is provided between the shuttle 9 and the sprue 6. As shown, the shuttle valve is provided in the end cap 8 of the injection machine but it may be in the walls of the mould itself. The invention may be applied to the making of laminar articles, e.g. having a foamed core. A first material is injected under a pressure higher than that on a second material, the latter pressure being increased while the first material is being injected so that it becomes greater than that on the first material when a sufficient quantity of the first material has been injected so that the shuttle slides to allow the second material to be injected. A second amount of the first material may be subsequently injected. Reference has been directed by the Comptroller to Specification 1,156,217.

Patent GB-730713-A (GB)
Title: Process for the treatment of yarns or fabrics of glass
IPC: C03C25/475
Filed: 1951-04-16
Abstract: Yarns, slivers or fabrics made of glass are treated by heating to a temperature above that at which stress release takes place, e.g. to 450-550 DEG  C., cooling suddenly, and then coating with a mixture of one or more thermosetting condensation resins and one or more substances having surface-active cations.  The latter substance may be quaternary ammonium compounds having a long aliphatic chain, e.g. monostearylethylenediamine trimethyl ammonium methosulphate or octadecylpyridinium hydrobromide. Suitable thermosetting condensation resins are urea-formaldehyde, melamine-formaldehyde, methylolurea and methylolmelamine, and an acid catalyst may be present to facilitate polymerization.  The treatment improves the suppleness and receptivity for dyes.  The sudden cooling may be obtained by contacting the material with liquids or gases.  In example 1, continuous glass fibre yarns are heated to 550 DEG  C. and then suddenly cooled, e.g. with a blast of air, after which they are treated in a bath containing a urea-formaldehyde resin precondensate, Fixogene NT, which is a compound formed by the condensation of urea with ethylolamine, emulsified paraffin, a condensation product from dicyandiamidine and formaldehyde, and formic acid.  Polymerization is effected by heating to 140 DEG  C.  In example 2, a fabric of glass fibre is heated to 500 DEG  C., suddenly cooled with cold water, and coated with a composition containing a melamine-formaldehyde resin precondensate, Liofix SB, which is a compound obtained by condensing cyanamide or dicyandiamide with formaldehyde, emulsified paraffin, octadecylpyridinium hydrobromide and phosphoric acid.  The treated materials may be dyed, e.g. with acid, substantive or vat dyes, and the colouring matter then fixed by applying a solution containing trivalent iron, chromium or aluminium.  Suitable apparatus is described for the treatment of fabrics in a continuous manner.

Title: Washing machine program control device
IPC: A47L15/46
Filed: 1960-03-14
Abstract: 948,628. Time - switches. HOLZER PATENTS A.G. March 14, 1960 [March 20, 1959; June 1, 1959; June 15, 1959; July 25, 1959; Oct. 24, 1959], No. 8823/60. Heading H2B. A programme control device, e.g. for washing- machines has a driving motor that has an axially displaceable armature driving in one position a timer and in the other position (to which it is urged by an increased magnetizing current through the motor) driving a stepping device which actuates programme contacts. Armature 5 drives a cam disc 14 through a gear train 7, 8, 12 and functions as a synchronous motor. The contacts 1, 2 and 3 close in sequence and one is selected in accordance with the time interval required. The effective contact shunts resistor 17 and thus increases the current through the stator 4. The armature now slides into the magnetic field against a spring 28 and a gear drive now exists between 7 and 20. This drive operates a drive to the programme switch 15 and a cam 23 rotates with cam 22 and tilts the shaft 30 to allow the timing train to disengage and the cam disc 14 returns to zero under a spring 16. The programme drive energization is maintained by a cam 22 operating hold-on contacts 26, 27 until the programme switch has completed one step. When this is completed the energization of the motor is reduced to that pertaining to the timing drive, pinion 7 disengages the programme drive and the shaft 30 is released by cam 23 so that the timing train again becomes operative. In an embodiment, the movement of the armature disengages a clutch in the programme train instead of the pinion 7 being disengaged from wheel 20.

Title: Improvements in or relating to a circuit arrangement for an automatic telephone exchange
IPC: H04Q3/00
Filed: 1954-03-26
Abstract: 752,375. Automatic exchange systems. TELEFONBAU UND NORMALZEIT GES. March 26, 1954 [April 11, 1953], No. 8906/54. Class 40 (4). In an exchange employing line finders, a combined line and cut-off relay operates over a first winding to the calling loop and is held over the same winding in a local circuit during the time that a line finder is hunting for the calling line. As shown, when the subscriber N initiates a call the decade relay D pulls up over winding D1 in series with winding T1 of the line and cut-off relay T, which does not operate. Relay D locks up over its winding D2 and short-circuits its winding D1, whereupon T operates, and locks up over T1 in parallel with D2, relay KU being operated so long as a free link is available. Operation of the start relay AN of the link causes the vertical magnet H of the line finder AS to interact with relay F until DP pulls up to the marked decade over the vertical bank dk, and locks over winding DP2. Relay F then interacts with the rotary magnet D (connected up by vertical off-normal contact k), S pulling up over wiper c to the marked line to switch through the calling line, and shunt down AN whereupon KU relapses. The local holding circuit for D and T is thus interrupted, and D restores. T also restores momentarily but is re-operated over winding T2 and wiper d, and holds over wiper c. Release. Relay DP is released from the selector, S and T fall away, AS is homed, and KU re-operates. All links busy. No KU relay is operated, so D and T cannot be energized. The caller receives busy tone from BZ. Incoming call. Relay T is operated over T2 from the final selector LW.

Patent GB-888772-A (GB)
Title: Method of producing alumina
IPC: C01F7/34
Filed: 1958-03-20
Abstract: Hydrated alumina is precipitated from an aqueous solution of an aluminium compound at pH 7-10,5 and the resultant slurry subjected to comminution to reduce the particle size and render it more uniform ("homogenization"), whereby the apparent bulk density after spray drying is increased, e.g. to 0,3-1.5 gms./c.c.  When the precipitation pH remains below 10, aging of the slurry at pH 10-11 is essential The alumina precipitate may be obtained by acidifying sodium aluminate solution with a mineral acid, e.g. nitric acid, or with aluminium sulphate solution.  The precipitation may be conducted at 70 DEG -130 DEG F. and the amount of solids in the mixture is generally from 4-9%.  Preferably the alumina is aged after formation at pH 10-11 for at least 15 minutes at 90 DEG -130 DEG F.: aging at lower pH values is also described.  The alumina may, if desired, be filtered and washed prior to the homogenization, and in the flow sheet (not shown) two filters are employed with an intermediate reslurry tank to which a flocculant such as glue or polyacrylamide may be added.  The homogenization may be performed with a homogenizing valve operating at 500-3,000 p.s.i.g., or by grinding or milling.  After homogenization, the slurry may be dried in a tray dryes or rotating kiln, but is prefreably spray-dried, e.g. at 500 DEG -1,000 DEG F., to a moisture content of 15-40%, whereby microspheres are produced which, after pelleting, may be fully dehydrated by calcination at 1,100 DEG -1,350 DEG F.  Catalytic materialr may be added to the slurry before homogenization or may be incorporated after drying.  Platinic chloride may be employed, with or without subsequent treatment with hydrogen sulphide or ammonium sulphide and, as activator therewith, hydrogen fluoride, hydrogen chloride or aluminium chloride, to provide 0,1-0,8% of platinum and up to 3% of halogen in the catalyst; the alumina may be impregnated or coated with 8-20% of molybdena; catalysts may comprise 10-25% of molybdena and 1-5% of cobalt oxide (supplied as ammonium molybdate and cobalt nitrate) or 10-30% of chromic oxide or tungstic or palladium oxide.  In one example, a hydrodesulphurization catalyst is prepared by adding ammonium molybdate and cobalt nitrate during the formation of the alumina and, after spray-drying, mixed with 1% of graphite, formed into pellets and calcined at 1,260 DEG F.  It is then used (a) in the desulphurization of a gas oil with a boiling range of 480 DEG -630 DEG F.; (b) in desulphurization, nitrogen removal and olefin saturation of a thermal naphtha with a boiling range of 196 DEG -430 DEG F. and (c) in desulphurizing a heavy vacuum gas oil with a boiling range of 480 DEG -860 DEG F.  Specification 737,429 is referred to.
