Filed: 1939-08-29
Abstract: 535.213. Titanium dioxide. PITTSBURGH PLATE GLASS CO. Aug. 29, 1939, No. 24804. Convention date, May 4. [Class 1 (iii)] In the production of titanium dioxide by thermal decomposition of a vaporized titanium halide, specially TiCl 4 , in the presence of an oxidizing gas, and in order to prevent the formation of large crystals the reaction mixture is maintained substantially out of contact with the inlet of the vapour into the reaction chamber by an atmosphere of halide. The necessary atmosphere of e.g. chlorine may be obtained from a tube surrounding the titanium chloride inlet or may be produced by the decomposition of the titanium chloride as in the operation of the apparatus shown in which the chlorine produced at the inlet 7 is swept back in its passage to the outlet 9. The oxidizing gas is introduced through an inlet 4 and a heating element 8 is enclosed within the inlet 7. In order to further minimize any reaction at hot surfaces in the neighbourhood of the inlet, the inlet may be formed of or coated with carbon with the object of reacting with any oxygen present at that point. In an alternative method drops of titanium halide may be sprayed through an atmosphere of chlorine into the oxidizing zone. Specification 535,214 is referred to.

Abstract: 1,043,986. Testing fuel injection pumps. FRIEDMANN & MAIER. June 24, 1963 [Aug. 11, 1962], No. 24971/63. Heading F1A. In a test stand for a fuel injection pump, in which the support for the nozzles and measuring glasses is mounted by a horizontal pivoted arm for pivotal movement from one side of the test stand to the other, the pivoted arm extends below a bracket only one end of which is fixed to the frame of the test stand and which is intended for fixing the pump to be tested. A support 4, Figs. 1 and 3, carrying testing nozzles 17 and a holder 11 for measuring glasses has an arm 13 provided with a slot 15 receiving a pin 14 about which the support 4 may be rotated through 180 degrees when it is fully extended laterally of the test stand. Only in this position can the curved end 18 of a bridge piece 19 pass between the pin 14 and a stop 24, thus the danger of collision of the support 4 with the test pump support bracket 20 or a pump mounted thereon is avoided. Two further stops 23 govern the two extreme angular positions of the support 4 lockable by a nut or handle 16. The stops 23, 24 may be replaced by a strip, and the stops or strip may have a soft covering such as rubber. The bridge piece 19 may be removed and the support 4 replaced. A frame 8, 9, supported by half-shells 10 and retractable to avoid obstruction, supports the holder 11 through half-shells 12. Thus the holder 11 and the frame 8, 9 may be moved to either side of the support 4 for reading the liquid levels in the measuring glasses. The latter are emptied by tilting, the discharged testing oil passing through a pan in the support 4, a conduit 26 in the arm 13 and a pan 27 in a bench 1 to a container below the bench. In a modification, Fig. 5, an extension of the pin 14 is gripped by plastic plugs (not shown) in the bore of a tube 34 connected by its ends to the bracket 20, the plugs being forced against the extension by bolts screwed into the ends of the tube 34. It is stated that in a known arrangement the pivot for the nozzle and measuring glass support is a large circular disc which is embraced by an annular horizontal arm of the support, and the pump under test is clamped to the bench and must be removed before the support can be swung from one side of the test bench to the other.

Breaks in the continuity of carded webs arising from stoppage of the doffer whilst the main cylinder is running are avoided by causing the doffer to restart in a manner to re-present to the main cylinder that part of its surface displaying a fibre gap. In the form of apparatus shown in Fig. 1, doffers 16, 16a are driven by reversible electric motors and pressure rollers 4, 5 and stripper and transfer rollers 17, 18, 19, 20 are driven from the doffer 16. Rollers 6, 7, 17a, 18a are similarly driven from doffer 16a. The feed members 11,12 are driven independently of the doffer 16 and, after a stoppage, they are started first to allow the cylinder 14 to be filled with fibres, then the doffer 16 is reversed for a few inches, followed by forward movement. Prior to stopping doffer 16a, the calender rollers 9 are stopped by means of a clutch or differential arrangement to provide an excess of web between pressure rollers 6, 7 and the calender rollers. An alternative arrangement employs a guide roller that normally deflects the web from a straight path but is moved away from its normal position when the doffer and rollers are to be reversed. Instead of reversing the doffers and other rollers, the stripper rollers 17, 17a may be moved away from the doffers until the fibre gap has passed them. This displacement of rollers may take place under the control of mechanical or electrical means. According to the Provisional Specification, the doffer may be driven through some form of epicyclic gearing and by providing a clutch to lock the planet gears a forward or reverse rotation of the doffer may be obtained. In another arrangement employing tandem cards and pressure rollers, automatic means may be provided for moistening the top pressure roller just before a fibre gap reaches it.
