Patent GB-822910-A (GB)
Title: A method for the vapour phase exothermic oxidation of a titanium halide
Inventor: SCHAUMANN HOLGER HEINRICH
IPC: C01G23/07
Filed: 1956-02-28
Abstract: In the production of titanium dioxide by the vapour phase exothermic oxidation of a titanium halide, oxide scale depositing on the internal wall surfaces of the reactor is removed during the reaction by moving over said surfaces <PICT:0822910/III/1> a scraping element internally cooled by means of ducts through which a cooling fluid is passed.  In the embodiment illustrated in Fig. 1, an oxidizing gas preheated to above 350 DEG  C. is introduced into cylindrical reactor 1 through conduit 2 and vaporized titanium tetrachloride is mixed therewith having been fed into the apparatus through conduit 6 and inlet 5 as a sheeted stream.  In an example the top lip of this inlet is said to be externally heated.  The products of reaction pass out through conduit 7 whilst a deposit 19 builds up on the reactor.  The scraping device has a serrated cutting edge 15 and is supported and operated by means of a vertical hollow shaft 11 and brackets 13.  The shaft 11 is provided with conventional sealing means 12.  A fluid coolant such as water is supplied to the head of the scraping device through the shaft 11 and ducts 17 in the brackets 13, and removed by means of concentric ducts 18.  The scraping device is rotated by a geared motor drive and vertically actuated by a hydraulic ram.  It may be moved intermittently preferably before 40% of the area of the reactor is blocked or it may be moved continuously. Removed oxide scale falls through the scraping device and is withdrawn through a shoot 8 adapted to be closed from the atmosphere.  Alternatively the scale may be removed with the gaseous product suspension and subsequently separated therefrom. Scraper heads consisting of segments of a circle or of arms provided with cutting edges which project from the rotatable shaft or of a helix supported by projecting arms from the rotatable shaft, are mentioned.  Examples refer to the use of the invention in the oxidation of a mixture of titanium tetrachloride, preheated to 950 DEG  C., with or without aluminium chloride with humid air obtained by preheating dry air to 1030 DEG  C. and burning acetylene therein.

Title: Improvements in packaging machines
Inventor: HILL DENNIS
IPC: B65B11/52
Filed: 1963-02-01
Abstract: 1,011,665. Blister packaging. FORGROVE MACHINERY CO. Ltd. March 5, 1964 [Feb. 15, 1963], No. 6303/63. Heading B8C. [Also in Divisions B5 and B6] A machine for packaging articles forms recesses or " blisters " in a web of material, e.g. heat-sealable thermoplastics material and includes means for cutting the web transversely after filling the blisters, comprising fixed and associated movable knives and one or more suction cups to lift the web into contact with the fixed knives, the cups also removing the individual packages from the machine. The blisters may be closed by a further web. A web of material 13, Fig. 1, is fed beneath a preheater 35 to a moulding section where one or two transverse rows of one or more blisters are formed using a heater 37 and vacuum mould (see Division B5). This section is movable longitudinally to effect correct registration and if the machine is stopped the heater may be swung away automatically to prevent web damage. Articles are placed in the blisters at 11. Pairs of drive rollers 25 and web margin engaging discs 26, 27 intermittently operated by piston 17 through a rack-and-pinion 18, 19 communicating motion to chains 23, 24 feed the web 13 and its associated top web 14 through the machine. A photo-electric device 32, Fig. 1, and associated clamp 33 may be provided to register the top web with the resulting packages (see also Division B6). The webs are sealed around the blisters by sets of bars alternately heated and water-cooled, and slit longitudinally between columns of blisters by rotating knives coaxial with the discs 27. At the transverse severing and discharge section, Figs. 9, 10, the webs come to rest with the blisters spaced between rails 60. Suction cups 64, 64A are moved down and grip the webs and lift them against the fixed knives 62, 62A. Operation of a piston 83, moving a rack 84, rotates a pinion 85 journalled to a shaft 86 carrying chain sprockets 87. Each chain 88 moves a slide 89 carrying a cutter wheel 63 maintained in contact with the fixed knives by spring means 98, along guides 90. As the slides advance, pinions 92 engaging fixed racks rotate the cutter wheels through gearing 94, 95 to sever individual packets. The suction cups 64A are moved in the feed direction to remove the leading packages from under the knife edge 62A, then all the cups are raised and lowered while remaining vertical by rotating the arms 65, 66 through 180 degrees, to discharge the packets from the machine. If a single blister or one row of blisters is moulded, suction cups 64A and one of the two transverse cutting means will not be required. If the top web is omitted the sealing section is redundant.

[Also in Group XXVII] A temperature-controlled clutch between a constantly driven shaft 1 and a freely-mounted engine-cooling fan 35, comprises a steel or phenolic resin clutch-nut 17, left-hand threaded on a shaft-mounted support member 9 of cast-iron or phenolic resin, and adjustably connected by a bi-metal spiral 21 to a cup 24 fast on the support 9 and having punched-out windows 26 which draw warm air from the coolant radiator over the bi-metal 21, causing the latter to screw the clutch-nut 17 rearwardly into frictional engagement with a bearing member 31, freely mounted, but dragging on the support 9, and carrying the fan 35, to which it has a lost-motion connection by screws 39 passing through arcuate slots in the fan. The initial frictional engagement between the clutch nut 17 and the bearing member 31 screws the nut further rearwards, tightening the bearing member 31 against the support 9, with or without an interposed plate spring, for rotation in unison with the shaft. On decelerating the driving shaft, the fan takes up the lost-motion with an impact which initiates unscrewing of the clutch-nut 17. The outer end of the bi-metal 21 has a screw and slot circumferential adjustment 23 in the cup 24.

Abstract: Pharmaceutical solutions, fruit juices, and other liquids sealed in thermoplastic containers are sterilized by heating at temperatures above the softening point of the thermoplastic material while completely immersed in a liquid or gas heat-exchange medium of a density lower than that of the liquid in the container, and then cooling to a temperature below the softening point.  The volume of liquid and gas at the sterilization temperature must be less than that of the container and the boiling point of the liquid being sterilized must not be less than that of the heat-exchange medium.

Filed: 1925-03-18
Abstract: 238,181. Kopf, P. Aug. 7, 1924, [Convention date]. Void [Published under Sect. 91 of the Act]. Automatic power control.-A locomotive is provided with two independent automatic braking devices operated from the track when a danger signal is overrun, one giving an ordinary application at an advance signal and the other an emergency application at a home signal. On passing a home signal at danger, valve 44 is opened and communication is established between the train-pipe, not shown, connected to inlet 49, and a cylinder 56. The train-pipe pressure raises a piston 55 uncovering a large vent 57, causing an emergency application and stopping the train. The piston 55 is connected with the arm 60 of a valve 61 which is opened when the piston is raised, establishing communication between the reservoir, not shown, and a pipe 65 leading to a cylinder 68, a piston 67 thereby being moved to uncover a port allowing the reservoir to vent through a whistle 69. At the same time a linkwork 73 is operated by the rod 70 of piston 67 to move a regulator, cutting off the steam supply.
