The extreme forward position 20a of the heater is closely adjacent to the welding electrodes 3, 4. In a modification (Fig. 2, not shown) the transformer is stationary and connected by flexible cables to a carriage on which the heater is mounted. In a further embodiment, Fig. 3, in which the wires and mesh are fed continuously the welding electrodes 3, 4 and the preheaters 20 are mounted on a reciprocating carriage 25. In a modification of this embodiment the electrodes and preheaters are mounted on separate reciprocating carriages which may be arranged so that the heaters complete their return movement and begin heating the longitudinal wires again before the welding electrodes begin returning. The preheating means may comprise an electric induction coil through which the wires pass (Fig. 4, not shown), a ring burner using, e.g. butane gas (Fig. 5, not shown) or electric resistance heaters (Figs. 6-9, not shown). In the latter case the heaters may accommodate one or two wires for simultaneous heating and may have provision for heating wires at various spacings. Feed movement of the heating means may be provided by means of clamps arranged to grip the advancing wire intermittently. In the case of electric resistance preheating the clamps may also form the resistance heating electrodes.

Abstract: 1290406 Gas analysis; analyzing gases electrically SCOTT RESEARCH LABORATORIES Inc 3 June 1970 [3 June 1969] 26878/70 Headings G1B and G1N Before passing combustion exhaust gases e.g. from an I. C. engine through a test chamber 23 containing a catalyst-coated resistance sensor 42 for measuring carbon monoxide or hydrocarbon content, they are passed through a scrubber 15 containing a particulate basic material, e. g. calcium or magnesium oxide or carbonate, or strontium carbonate or barium carbonate, to effect solution of acid gases in water present in the gases, and through a water separator 17, to reduce the risk of poisoning the catalyst. The test chamber 43 is formed in a cylindrical aluminium block 22 wrapped in an electrical heating jacket 40, and contains aluminium wool in its entry position. The gas under test enters the chamber 23 via a line 21, combustion air from an inlet 29 and a water separator 30 being introduced via a line 26. Both inlets have control orifice plates 27, 28. A pump 35 connected by a line 34 to the chamber 23 draws the gases through the apparatus. Cooling air for an electric motor 37 driving the pump is drawn into an inlet 38 adjacent the scrubber 15 to cool the latter. The sensor 42 is of tungsten coated with a catalyst in a suitable cement. A compensating sensor 43 is identical apart from the omission of the catalyst. The sensors are connected in a bridge circuit Fig. 6 whose unbalance indicates the change in resistance of the sensor 42 due to oxidation of the carbon monoxide or hydrocarbon of the gases in the presence of the catalyst. To calibrate the bridge meter 54, a standard substance, e.g. methanol, formaldehyde, or formic acid, from a canister 44 is passed through the test chamber 23. The catalyst may be Hopcalite, which at a gas temperature of 475‹ F. detects carbon monoxide, or at 650‹ F. detects hydrocarbons. Vanadium pentoxide at gas temperatures below 750‹ F. may be used to detect hydrocarbons in the presence of carbon monoxide. Chromium oxide is another possible catalyst. Exhaust gases are collected by inserting the end of a pipe 13 in the exhaust pipe of the engine, the pipe 13 being of considerably smaller diameter than the exhaust pipe.

Abstract: 1309733 Continuous winding of filamentary material onto flanged spools DAVY PLASTICS MACHINERY Ltd 2 June 1970 [3 June 1969] 28034/69 Heading D1J In the continuous winding apparatus shown, in Fig. 2, when the left-hand spool is full the empty right-hand spool is accelerated until the peripheral velocity of the barrel of the empty spool is equal to the linear speed of the wire 30 being wound. The guide roller 23 is then displaced by the screw means 24' to a setting such that the wire 30 from the full spool contacts the barrel of the empty spool as shown. According to the invention deflectors 27, carried by a post 26, then move to a setting pushing the wire onto a snagging hook carried by an annular chamber rotating with the full spool and so cause one or more turns of the wire to be wound in said chamber. The wire deflector 27 is then moved to a setting pushing the wire onto a snagging hook carried by an annular chamber rotating with the empty spool and so cause the wire to enter said chamber. The wire extending between the two chambers is severed by fixed knives (35), Fig. 1 (not shown). Further rotation of the empty spool causes the wire 30 to be wound onto the empty spool. By transferring the wire into the annular chamber associated with the full spool before the wire is severed, the tail end of the wire is retained in the annular chamber by centrifugal force.  Fig. 3 shows a cross-section through one of the aforesaid chambers. The upper and rear wall of the chamber 10 are provided by an annular plate 13. Friction pads 14 are so positioned that the plate 13 normally rotates with the mandrel 2 on which the take up spool is mounted. A peripheral brake 17 can be actuated to act on the plate 13 and reduce its speed relatively to that of the mandrel 2. In order to increase the length of the wire contained in the chamber of the right-hand spool the brake 17 is actuated as soon as a few turns have been wound onto the empty spool. This causes the snagging hook carried by the plate 13 to slow down relatively to the spool and so cause wire to be wound off the barrel of the right-hand spool and into the chamber 10 where it is retained by centrifugal force. The brake 17 is then released and the plate 13 accelerates to the speed of the spool.  When the right-hand spool is full, an empty spool on the left-hand spool is brought up to speed and the guide roller 23 is moved to a setting such that the wire 30 is tangential to the barrel of the empty barrel. The wire is then transferred to the left-hand spool in the manner described with respect to the righthand spool. The annular chambers 10 prevent the severed ends of the wire from lashing and damaging the machine whilst a spool is being brought to a standstill.

Abstract: 1310011 Active fibrous carbon DEFENCE SECRETARY OF STATE FOR 8 April 1970 [8 Jan 1969] 1150/69 Heading C1A Active fibrous carbon, i.e. filaments, yarns or fabrics of carbon are formed by passing a fibrous organic material 6, upward relative to a source of heat, e.g. electric elements 3, so as to heat the material through a carbonizing temperature range of up to 600 C., the material being spaced from the heating source so as to permit an upward convective gas flow between the fibres and the heat source so as to remove volatile decomposition products from the carbonized material, and then contacting the carbonized material at a temp. between 600 and 1000 C. with CO 2  or steam to activate it. The organic material may be a polymer fibre containing at least C, H and O, e.g. it may be, oxidized polyacrylonitrile, polyvinyl alcohol or carbohydrate polymersuch as viscose rayon, cuprammonium rayon, or cellulose ester rayon. The convective gas flow over the organic material may be increased by admitting additional gas to the furnace, e.g. through inlet 12 to give a total gas flow relative to the surface of the material between 50 and 25 cm./minute. This gas may be the activating gas, i.e. CO 2  or steam, and the heating elements 3 may be arranged so that the organic material is carbonized, raised to activating temp. and activated all in a single furnace, the speed of the material through the furnace being such that it has a residence time at its critical decomposition temp. of at least 15 mins. The speed of the feed rolls 6, 9 and take-up rolls, 10, 8 may be adjusted to submit the material to tension during carbonization and/or activation. Between 0À1 and 10% of a Lewis acid selected from the dihalides of Ba, Ca, Mg and Zn, and the trihalides of Fe, Cr and A1 may be incorporated into the organic starting material.
