Abstract: 1294929 Treating ore DER DILLINGER HUTTENWERKE AG 29 Jan 1970 [30 Jan 1969] 4225/70 Heading C1A In treating an ore, for example by pelleting or sintering, the charge of ore is moistened by adding thereto the dust in water dispersion obtained by the spray precipitation treatment of waste gases from oxygen blowing or blast treatment in the steel industry. Dirty water fromsuch spray precipitation treatment is fed by pipe 1 into a cyclone 2 in which the heavier dust particles separate out and are fed via pipe 5 to a tank 6 in which settlement occurs, the deposit being removed by chain conveyer 7. The lighter dust dispersed in water is fed into thickener 4 by pipe 3. The resulting mud is pumped by pumps 12 and 13 through pipes 10, 11 and 14 finally into mixing drum 15 where it is mixed with the ore to be pelleted or agglomerated. The pumping speed of pumps 12 and 13 may be varied to cope with the varying moisture requirements of the ore. The system may be fitted with water supply, e.g. via pipes 17, 23, 22, by means of which the system may be flushed or kept operating if a blockage occurs in the mud flow line. The water line 17 is fitted with pump 16 and connections 18, 19 and 20 which ensure that blockages both before and after the pumps may be coped with. A recycle line 21 is fitted adjacent the end of mud line 14 which when valve 25 is closed serves to return any water used for flushing back to tank 6. The water requirements of drum 15 are satisfied by line 22 during such flushing operations. Blockages of the mud line may be minimized during stoppages of the mixing drum or sinter plant, by utilizing line 21 to return all the mud from line 14 back to the tank 6. Valves are positioned as required by the operational demands of the system and additional water supply points are provided.

The as-spun filaments may have a tenacity of greater than 0À6 g.p.d. and an elongation at break of less than 15% and are, suitably, heated at a temperature between 100‹ and 175‹ C., a temperature between 115‹ and 150‹ C. being preferred, for one minute or more. After the heat treatment at constant length the filaments may be hot drawn at a draw ratio of from 2:1 to 8:1, preferable draw ratios lying between 4À5:1 and 6À5:1, and are then heat set at constant length at a temperature higher than any used in previous steps of the process. The hot drawing process is suitably carried out within the preferred temperature ranges indicated for the heat treatment under constant length and may be conducted in air or an inert atmosphere, for example, nitrogen or steam and the heat may be supplied by one or more hot rolls, hot shoes, heated tubes or ovens. Filaments produced by the process show improved hot-wet modulus, tensile factor, tenacity and elongation at break. The dry-spinning of a terpolymer comprising 95 wt. per cent acrylonitrile, 4À5 wt. per cent methylacrylate and 0À5 wt. per cent sodium methallyl sulphonate from an aqueous solution of acetonitrile is exemplified.

Abstract: 1297501 Discharge apparatus HORIZONS Inc 2 Jan 1970 [8 Jan 1969] 271/70 Heading H1D [Also in Divisions B6 and C7] An X-ray image intensifier comprises a laminar arrangement of means for absorbing X-rays, and means for transforming the resulting photc electrons into either secondary electrons or charged particles which are multiplied and accelerated towards an electron- and/or charged particle-sensitive receptor 16. In the arrangement shown an electrode 12 adjoins an insulating film 14, e.g. of plastics material, supporting the receptor layer 16. Electrode 10 may be a thin sheet of Al or may also act as the X-ray absorber in which case it should contain a high proportion of elements having an atomic number higher than Ag, e.g. Pb, Bi, U, Th and their compounds, which may be dispersed in a partially conducting plastics film to act as an electrode and a multiplying structure. A separate multiplication layer 18 is preferably provided and may act in either the Geiger-Muller or secondary emission mode. For the G-M mode the layer 18 contains a gas, e.g. A or N, with a quenching gas such as alcohol, methane or a halogen, confined by insulating spacers 22 which are not necessarily hermetic seals since electrode 12 may be a metallic surface in a cassette which can be filled with the gas at a pressure of a few mm. up to atmospheric. The region 18 may be a porous film, open mesh, a grid, or a layer containing a large number of channels formed by anodic etching (see Division C7) or by a photo-resist etching process (see Division B6). The electrode 10 is positive for the G-M mode and negative for the secondary emission mode. For the latter mode the channels are lined with a compound of high atomic number to act as an X-ray absorber and with secondary emitting material, e.g. alkali metals or alkaline earth metals. The channels retain the resolution of the incident X-ray pattern. In alternative embodiments (Figs. 2, 3 or 4, not shown) an additional electrode is provided above the layer 16 to provide what is in effect a voltage divider circuit. A power source connects the additional electrode to either or both of electrodes 10 and 12, depending on the insulating properties of the layer 14. In a further alternative embodiment (Fig. 5, not shown), the electrode 12 is provided on the opposite side of the insulating layer 14. Examples of suitable receptor layer compositions are given.

The housing 1 is connected by a saddle member 6 to the vehicle steering column. The lock cylinder is connected by a member 17  rotatable with and slidable within a shaft 10 to an ignition and starter switch mechanism. The cam 11 moulded with the shaft 10 is rotated by the key in the lock cylinder when turned to ignition or start to withdraw the bolt. A spring- urged detent 26 engages a projection 19 on the member 16 moving with the cylinder 9 and prevents movement of the key to lock position. The key is turned to auxiliary position to free the projection 19 from an abutment 22 on the lock housing and allow depression of the lock cylinder and member 16 to disengage the detent 26. The projection 19 engages surface 20 of the slide 13 and a spring-urged detent 23 in the member 16 engages a projection 25 on the lock housing. The tip of the key prevents inward movement of the detent 23 by withdrawing the key, the detent moves inwardly to disengage the projection 25 and the cylinder 9 and the member 16 then move outwardly under the action of the spring 18, thereby freeing the bolt which moves to a locking position. A spring-urged plunger 33 completes a circuit from a terminal to earth when the bolt is withdrawn. The device may include a pair of contacts in circuit with a visual or aural warning and which are closed by the key in all or predetermined key positions in the lock.
