[Also in Division E1] Earth boring equipment comprises a drill 41 and a concentric drill 49 both rotated by rods 9, 27 and non-rotary tubing 71, 73 enclosing the rods and arranged to follow the drills and permit retraction of the drill 41 and the rods through the tubing. The rods are driven by means of an adaptor 1 from a hammer drill 3 having mechanism 4 for rotating the adaptor 1 and movable on a feed bar 61 by chains 63. The tubing is attached to the hammer drill by chain 85 and runs in guides 66 on the feed bar. The adaptor 1 rotates on the tubing head fitting 97 which is axially movable relative to the tubing. Flushing water is supplied to the drill 41 and the rods through bushing 83 and to the space 90 outside the rods by line 14. A non-return valve 88 is interposed in the line 14 so that the fitting 97 may be reciprocated relative to the tubing to cause the flushing water to clear obstructions between the drills. Flushing water leaking from joints in the tubing acts as a lubricant for the tubing. The drill 41 is connected to the rod 27 by an adaptor 33 having splines 46 adapted to rotate the drill 49 which has limited axial movement in the lower part of the tubing. The drills have radial hard metal inserts 42, 50. When, during the drilling of a hole 91, solid rock 69 is encountered, the drill 41, adaptor 33 and the rods are removed from the tubing and the rods and drill 41 are returned to drill a hole 93, the supply of flushing water from the line 14 being discontinued. After completion of the hole the drill 49 and tubing may be withdrawn.

Abstract: 139,505. Fritze, H. Oct. 30, 1918, [Convention date]. Void [Published under Sect. 91 of the Act]. Lighting and heating systems. - The current which may be supplied from a generator of limited output is adjusted so that as each of a number of unipolar or multipolar burners for welding or soldering is put into circuit the output limit is raised by that required to supply one burner. The generator G has an additional separately excited field winding V with a resistance in series, equal sections W of which are short-circuited as each burner is placed in circuit. This may be effected by main or shunt-current relays in the burner or generator circuits or by current or potential transformers acting directly or through relays. A contact switch upon the handie of the burner or outside the burner operated mechanically or electrically may be used to effect the variation of output limit. As shown in the Figure, a relay R1, R2 with a coil in series with the burner B<1>, B<2>, short-circuits the resistance section W related to it when the welding arc is struck.

Patent GB-375798-A (GB)
Title: Improvements in the chlorination of iron sulphide containing material
IPC: C01B17/06
Filed: 1931-02-26
Abstract: In the recovery of sulphur from materials containing iron and other sulphides by treatment with chlorine, the operation is so conducted that ferric and sulphur chlorides are vaporized and condensed, the separated sulphur chloride being used to treat further sulphide material and produce ferrous chloride and p  elementary sulphur.  The ferrous chloride is chlorinated, the ferric chloride formed being combined with that first produced and treated with steam to produce ferric oxide and hydrogen chloride which is catalytically oxidized by air to form chlorine for re-use.  Finely ground material is treated in a rotary reaction chamber at 300-400 DEG  C. with an excess of chlorine, metallic chlorides other than ferric chloride, such as those of nickel and copper, remaining in the residue.  Any sulphur chloride carried from the condenser by inert gases with which the chlorine may have been diluted is arrested by passage through a tower containing sulphide material; the stripped gases are passed over the separated ferric chloride and entrained sulphur chloride is removed by a second iron sulphide tower.  The sulphur chloride is used to treat further sulphide material and form ferrous, nickel and copper chlorides and liberate sulphur which is condensed, the reaction being carried out in a rotary chamber having a temperature of 450 DEG  C. at the charging end and 300-350 DEG  C. at the discharging end. Separation of the chlorides is effected by chlorinating the hot residue at 300-350 DEG  C., the vaporized ferric chloride being condensed, mixed with that initially formed and hydrolyzed with superheated steam at 300-400 DEG  C.  The mixture of hydrogen chloride and water vapour is dried by sulphuric acid and treated with air, at 420-500 DEG  C., to produce chlorine in the presence of a catalyst consisting of copper or nickel sulphate or chloride distributed over pumice &c., or formed in situ by the action of the hydrogen chloride on copper oxide carried by the pumice.  The action does not proceed to completion and, after being dried, the gases may be passed through further reaction towers.  Any remaining hydrogen chloride is separated by washing with water and the chlorine is dried by sulphuric acid which is mixed with the washing water and concentrated, the part of the steam containing hydrogen chloride being used to act on the ferric chloride.  Specifications 7107/13, [Class 1 (ii), Inorganic compounds, other than &c.], 374,070, and 375,795 are referred to.

Title: Improvements in and relating to winding machines
IPC: B65H67/06
Filed: 1952-03-10
Abstract: 734,930. Supplying tubes &c. to winding mechanisms. REINERS, W. March 10, 1952 [March 10, 1951], No. 6154/52. Classes 120(2) and 120(3). A winding machine having a plurality of independently operating automatic winding mechanisms each with a receiver device 36 to which empty tubes 12 (or full supply bobbins) are delivered from a conveyer 9 and from which the tubes 12 are transferred to the winding mechanisms, comprises feeler means 19 adapted to be periodically positioned by the movement of the conveyer so as to detect the presence or absence of a tube 12 in each device 36 and to initiate release to each empty receiver 36 of a tube 12 on the conveyer 9 and means automatically operable during the transfer of a tube from the receiver 36 to the winding mechanism temporarily to prevent release of a tube from the conveyer 9 to the receiver 36 until the transfer has been completed. In the embodiment of Fig. 1, the tubes 12 are supported in holders 11 on the conveyer 9, each holder being closed at the botton by a movable flap 13. As an empty tube 12 comes to a position for possible transfer, a projection 20 on the conveyer 9 moves a spring-biassed linkage 21, 22, to rock the feeler lever 19 to test for the presence of a tube 121 in the receiver 36. If one is not there, the linkage 18, 17, 15, opens the flap 13 to release a tube 12 to the shoot 8. If a tube 12<SP>1</SP> is present, the spring 33 absorbs the movement of the linkage 21, 22 and no tube is released from the conveyer. The release of a tube 12 from the conveyer 9 during bobbin-changing at the winding mechanism is prevented by a control cam 28 through a rocker 27 and link 24 which moves the link 22 from contact with the arm 21 and prevents the feeler 19 from being operated. In two further modifications the empty tubes are dropped from verticallyarranged tubular holders, carried by belts, the holders being closed at the bottom by movable flaps, into stationary vertically-arranged tubular receivers, also closed at the bottom by movable flaps, the presence of a tube in a receiver being tested by a feeler device carried by the conveyer. The receiver flaps are maintained closed during the bobbin-changing operation at the winding mechanism by a cam 28 as in the above modification.
