Title: A method and a plant for continuously cooling and solidifying by temperature lowering substances that are liquid hot and particularly pitch, bitumen, asphalt, resins and the like
IPC: B29B13/04
Filed: 1945-09-28
Abstract: Apparatus for cooling and solidifying resins, colloids, bitumen, pitch, and other substances, comprises an endless belt conveyer composed of fine mesh wire cloth of smooth surface, on to the upper lap of which the substance to be <PICT:0600685/IV(a)/1> <PICT:0600685/IV(a)/2> cooled is spread in a thin layer; low-feed atomisers for spraying a liquid coolant on to the underside of the upper lap over a substantial portion of the length between the point at which the molten substance is deposited and the other end of the lap; and atomizers for spraying a liquid coolant, such as water, which readily evaporates at the temperature of the molten substance (a) on to the upper lap of the conveyer just to the rear of the point of deposition of the molten substance and (b) on to the layer of the substance just in front of the point of deposition.  At the delivery end of the band, the solidified material may be caused to scale off by arranging for the band to make a sharp bend as it passes round an end supporting roller.  As shown in Fig. 1, molten substance from container G flows on to apron E and then on to band C, which is cooled by water sprayed from nozzles d.  Cold water is sprayed on the upper surface of the band from nozzles K and from nozzles M on to the molten substance.  The amount of water sprayed on to the material is preferably restricted so that it all evaporates before the solidified material leaves the band.  The spreading device, Fig. 2, comprises container G with apertures O arranged above the band and uniformly distributed across the width.  The flow is controlled by a spindle with conical valve P and centring needle P2.  As shown, the liquid streams are first received on sloping aprons E and spread into thin layers, but they may be received directly on the band.  The Specification as open to inspection under Sect. 91 comprises also apparatus provided with a steel belt instead of the wire cloth belt. This subject-matter does not appear in the Specification as accepted.

Title: Resilient car-seat carriage
IPC: B60N2/70
Filed: 1966-06-07
Abstract: 1,133,157. Resiliently mounted seats. NORDPATENT A.B. 7 June, 1966 [9 June, 1965; 13 May, 1966], No. 25313/66. Heading A4U. In a resilient vehicle seat mounting, in which the occupant's weight is preferably supported by rubber belts 20, tensioned between a stationary bar 21 and a moving bar 19, the adjustment of the position of the bar 21, relative to the base frame 11, is assisted by tensioned coil springs 26, tending to counterbalance the tension exerted by belts 20, on bar 21. The adjustment is effected by screwing rod 23 into or out of fixed nut 24. As the seat oscillates vertically on arms 14, the shafts 13 are rotated in their bearings 10 to vary the angular positions of crank arm 17. The front pair of arms 17 are pivoted to bar 19 and connecting rods 18, so that together with the rear pair of arms 17, they provide a parallelogram linkage. The upper limit of travel of the seat may be adjustably determined by movable abutment member 27. A shock absorber 31 offers higher resistance to upward motion of the seat than to downward motion. The seat mounting is slidable in the fore-and-aft direction to a position determined by the engagement of a fixed projection (39) between one pair of teeth of rack 37.

Title: Improvements in or relating to vacuum brakes for railway or like vehicles
IPC: B60T13/46
Filed: 1931-09-09
Abstract: 386,362. Fluid-pressure brakes. ALGRAIN, P., 198, Rue Parmentier, La Croyere, Belgium. Sept. 9, 1931, No. 25314. Addition to 386,333. [Class 103 (i).] A vacuum brake as described in the parent Specification comprises a separate vacuum reservoir 17 divided into two chambers 17a, 17b in which exist respectively the counter-pressure acting on the regulating valve 4 and the counter-pressure existing in the brake cylinder 2. This device prevents a fall in the braking force due to the compensating action of the valve 4 on an accidental increase due to leakage occurring in the pressure in the chamber 2a acting on the working surface of the brake piston. If this pressure increase occurs the needle valve in the regulating valve 4 described in the prior Specification connects the brake cylinder working pressure chamber 2a and counter-pressure chamber 17a by means of a pipe 13a and causes a compensating increase in the counter-pressure. In the present invention the braking force is maintained by ensuring that the counter-pressure in the brake cylinder chamber 2b is less than the increased counterpressure determined by the compensating movements of the regulating valve. Only when this increased counter-pressure in the chamber 17a produced by the needle valve of the valve 4 is sufficient to compress a spring 17e, is a piston 17c depressed to increase the pressure in the chamber 17b connected by a pipe 13 to the counter-pressure chamber 2b of the brake cylinder. Pipe 13a is closed by downward movement of the piston 17c. The counter-pressure chamber is evacuated on brake release through ball valves 13c, 60.

Title: Improvements relating to the manufacture of moulded building blocks
IPC: B28B7/18
Filed: 1948-09-29
Abstract: 651,617. Moulding hollow building blocks. OBO CONSTRUCTION CO., Ltd., and OATLEY, A. E. Sept. 29, 1948, No. 25404. [Class 87 (ii)] In moulding hollow building blocks, the cores for forming the cavities are longer than the required cavities and are withdrawn to their required positions during the filling of the mould, so as to draw in and consolidate the moulding material. Mould box 18, divided by partitions 33 to contain four blocks, rests on a table 17 which is in turn supported on a framework by means. of rubber blocks 16. Projections and recesses in the blocks are produced by means of profile strips 34, 36 whilst the cavities are formed by means of hollow cores 37 mounted rigidly on a platen 38 moved by a hydraulic ram. The platen is first raised to the position shown in Fig. 5 in which the cores 37 project above the top of the mould box 18 into a feeding box 76 fitted on to the top of the mould box. As concrete is poured into the mould, vibrators 77 underneath table 17 are set in motion and the cores 37 are lowered until their upper ends are level with the top of the mould box 18. The vibration is then stopped, the concrete tamped, and surplus removed. Next, the cores are lowered below the table 17 to a position in which the upper ends of guide-rods 44 are situated just inside holes 47, Fig. 4, in brackets 48 on the mould 18. Apertured slidebars 49 which do not normally obstruct the passage of the rods 44 are slid to a position in which they block the holes 47. Therefore, when the platen is again raised, the moulding box 18 containing the four moulded blocks 24 supported upon bars 74, is lifted off the table 17 catches 56 engage the bracket 48 as shown in broken lines on Fig. 4. A metal frame (not shown) carrying four wooden pallets is then slid into the gap between the bottom of the mould box and the table 17. The slide-bars 49 are then pulled rearwardly so that the guide-rods 44 have an uninterrupted upward path and the supporting bars 74 are withdrawn. The platen is again raised until the blocks 24 supported upon their platens have been ejected from the moulding box 18, and are withdrawn.

Title: Preparation of phenylalkylchlorosilanes
IPC: C07F7/12
Filed: 1958-08-11
Abstract: Zirconium tetrachloride is used as catalyst in the redistribution reaction, at elevated temperatures, between phenylsilanes of the formula (C6H5) m SiRnCl4-m-n and alkylsilanes of the formula R1p Si Cl4-p, where R and R1 are alkyl radicals, m is 2, 3 or 4, n is 0 or 1, m + n not being more than 4, and p is 1 or 2, to prepare phenylalkyl chlorosilanes.  Instead of the tetrachloride, zirconium metal or a compound thereof which is converted to the tetrachloride under the conditions of the reaction, may be employed.  Such compounds include zirconium acetate, hydroxide and oxychloride, and, less desirably, the tetrabromide and tetraiodide.  The temperatures are preferably above 125 DEG C., and although atmospheric pressure may be employed, pressures of about 100 to 750 p.s.i. are preferred. The proportion of catalyst is generally from 0,1 to 10% by weight of total reactants, and it may be used on an inert support such as alumina.  The reaction is improved by the addition of small amounts of silanes containing silicon-bonded hydrogen, e.g. MeSiHCl2, PhSi H Cl2 and Me2 Si H Cl.  Examples are given, including comparisons with aluminium chloride as catalyst and HSiCl3 as promoter.

Abstract: 1,036,753. Injection moulding machines. AMERICAN CAN CO. July 1, 1963 [Nov. 23, 1962], No. 25960/63. Heading B5A. Apparatus for forming moulded articles comprises relatively movable male mould members 25, 26 and female mould members 11, 15, 16, which are controlled by sleeves 18, 17 so that in operation the male members are moved away to leave a moulding retained in the cavity by the separable mould parts 15 which are then opened to release the moulding. In an injection moulding machine for moulding collapsible dispensing containers, the female mould members comprise a stationary die housing 11 having inclined walls 14, and an external neck-forming means 15 urged upwards by a collar 16 which is maintained in position by an outer movable sleeve 17. The sleeve 17 is seated on the flange 18a of an inner movable sleeve 18, itself supported by a movable plate 19. The shoulderforming part 25 of the male forming tool is bolted in the axial passage 18b of sleeve 18, and itself supports the part 26 which shapes the internal surface of the neck of the tube. In operation a thermoplastic sleeve 40a is located on the shoulder former and the parts assembled as in Fig. 1. Thermoplastic material is injected through a nozzle 44 to form the neck. The plates 19, 20 are then lowered causing the sleeve 18 to descend, carrying with it formers 25, 26 to release them from the tube headpiece 40b. When a bolt 30 on inner sleeve 18 bottoms in a slot 31, movement of plates 19, 20 causes descent of sleeve 17 against the action of springs 22a, and hence collar 16 drops. The spring forces on thread plates 15 cause them to slide along walls 14 freeing the moulded article. Air may be supplied through an orifice 26e to completely eject the formed tube 40.
