Title: Improvements in and relating to revoking mechanism for weft replenishing looms
IPC: D03D45/20
Filed: 1938-08-03
Abstract: 500,172. Looms with automatic weft replenishment. CROMPTON & KNOWLES LOOM WORKS. Aug. 3, 1938, No. 22920. Convention date, Feb. 26. [Class 142 (iii)] Shuttles, changing bobbins and other weft carriers in, automatically.-The latch 18 pivoted to the transferrer hammer 19 is lifted into position to be operated by the lay dagger 17 by a rod 71 having a yieldable connection 73 with its operating lever. This connection comprises two jaws 73, 78, the former notched at 74 and the latter straight-faced and pivoted to the jaw 73, towards which it is drawn by a spring 77. When the weft feeler 46 indicates shortage of weft the electromagnet 42 couples a normally stationary lever 32 to a lever 38 oscillated by a cam 36 on the bottom shaft 35. The various parts are then in the positons shown, and the lever 32 lifts the rod 71 to move a lever 64, and so bring the latch 18 and the shuttle feeler 66 into operative positions determined by the stop pin &c. 90, 91. The lever 32 continues to rise and forces its pin 80 out of the notch 74 into the position 75 between two parallel jaw faces. From this position the pin is displaced to the position 76 by the exertion of a very small force which may be due to the feeler 66 contacting with a shuttle before the latch 18 and dagger 17 engage thus revoking bobbin transfer, or due to a dagger 93 coming in contact with the lever 64 after the latch and dagger having engaged, in which case transfer will take place. On the fall of the lever 32 after the lever 64 is arrested by the stops 90, 92, the pin 80 will be lowered into the notch 74 again. Specification 485,884 is referred to.

Title: Improvements relating to railway signalling systems
IPC: B61L23/16
Filed: 1926-09-17
Abstract: 282,484. Tattersall, A. E., Downes, F., and, Westinghouse Brake & Saxby Signal Co., Ltd. Sept.] 17, 1926. Electrical systems, non-automatic.-In systems in which a temporary current is transmitted over the rails of a section between two cabins when it is desired to pass a train over the section, slow releasing relays are directly connected to the track rails and con trol the release of a starting signal lever or other device. The slow release is of such duration as to avoid the need for maintaining energization of the relays, and may be provided in any suitable way, as by adjustment of the air gap separating the armature and the poles of the relay when de-energized. Fig. 2 shows two cabins A, B at ends of a section. The circuits at A are for use where the cabin is close to the end of the insulated section of rails 1, 2; those at B for use where the cabin is some distance away. The relays 5 are slowreleasing and are normally connected across the track rails 1, 2 through the contact 6 of plunger 7 or the contact 26 of relay 24 which is energized by depression of plunger 7 at. B. When plunger 7 is depressed the battery 8 is connected across the track rails. The starting levers are controlled by electromagnets 4 and direction levers by electromagnets 19; the latter are provided to prevent admission of trains to the section from both' ends at once, and control line-relays 21, which in turn control the starting lever lock magnets 4. To pass a train from A to B, A depresses plunger 7 and relay 5 at B is thereby energized, closing contact 11 and energizing repeater relay 23. Contacts 27 of relay 23 close the circuit to the lock-magnet 19 of the direction lever, which may then be reversed. B then closes plunger 7 and, if the starting signal lever is normal and contact 9 is closed, relay 24 is energized and battery 8 at B connected to the rails 1, 2 to energize relay 5 at A. Current is also transmitted from battery 12 at B over contact 16 of the reversed direction lever at B, wire 22, contact 15 of the normal direction lever and relay 21 at A and return wire 28. The starting signal lever lock magnet 4 at A is energized from battery 12 at A over contacts of relays 5, 21. The direction lever at B is released for restoration by depression of plunger 7 at A, thereby energizing relay 5 at B; repeater relay 23 then completes the lock-magnet circuit. A simplified arangement of apparatus without the direction levers is also described.

Title: Pulse generating circuits using electric discharge tubes
Inventor: RANSOM DAVID HIRAM
IPC: H03K29/00
Filed: 1947-08-20
Abstract: 647,963. Pulse generating circuits. STANDARD TELEPHONES & CABLES, Ltd. Aug. 20, 1947, No. 23099. [Class 40 (vi)] A pulse generator circuit comprises a cold cathode gas-filled sequence tube of the type described in Specification 639,827, so that when one gap is fired the spread of ionization causes a succession of gaps to fire in turn the firing of any gap producing a pulse in an output circuit and means whereby any gap may be selected to fire first. The Figure shows a sequence tube 16 having a cathode 17 and anodes 18-27 used in a circuit for producing a predetermined number of impulses by depressing any given one of a series of keys K1 ... K0. When any key is depressed battery 3 is connected across resistors 9, 10 and neon 11, via transformer winding 28 and key contacts.a, b and the neon fires and a further circuit is made from terminal 2 to cathode 17. If it is required to generate, e.g. five pulses, key K5 is depressed, the associated anode 22 is connected to the higher potential line 29 and the gap 22, 17 fires and ionizes the gas in the adjacent gaps. The anodes 23-27 to the right of anode 22 are disconnected from the lower potential line 30 when key K5 is depressed and therefore do not fire. The anodes 18-21 to the left of gap 22 remain connected to the line 30 and fire in sequence as ionization spreads from the adjacent gaps, the voltage on line 29 being insufficient to cause any gap to fire in the absence of ionization migration from an adjacent fired gap. The cathode current of tube 16 thus increases in step wave-form and five pulses of current flow in the output winding of transformer 7. The line 30 may be disconnected from terminal 31 and connected to terminal 32 when only gaps associated with keys to the right of the depressed key will fire.

Title: Improvements in or relating to the treatment of industrial liquors containing sulphuric acid to remove the acid therefrom
IPC: C01B17/58
Filed: 1944-11-24
Abstract: Iron sulphide is added to industrial liquors to convert their sulphuric acid content to iron sulphate and hydrogen sulphide, and the iron sulphate is converted to iron sulphide for reuse by treatment with a metal sulphide or hydrosulphide having a solubility product greater than iron sulphide.  The hydrogen sulphide may be oxidized to sulphur, sulphur dioxide or sulphuric acid.  Preferably an alkaline earth sulphide or hydrosulphide is used, and the precipitate of alkaline earth sulphate and iron sulphide reduced, e.g., with petroleum coke at 1000 DEG C. to regenerate alkaline earth sulphide.  The latter may be leached out with water in the case of barium, or as more soluble hydrosulphide using water and hydrogen sulphide under pressure in the case of calcium.  Alternatively, the mixed iron sulphide/alkaline earth sulphate precipitate may be added direct to the sulphuric liquor and only the undissolved residue reduced.  Alkali metal, e.g., sodium sulphide, may also be used, the sodium sulphate being discarded or if economic, recovered by evaporation and reduced, e.g., with carbon at 850-900 DEG C. to sodium sulphide for reuse. Excess from sulphide arising from the iron sulphate content of the original liquor may be used as a source of hydrogen sulphide or sulphur dioxide.  If the liquor contains titanium, then titanium hydroxide, suitable for conversion to titanium dioxide pigment, is precipitated on neutralising with iron sulphide.  Examples are given.  Specification 20900/12, [Class 1 (ii)], is referred to.
