Title: Improved method and means for washing wool
IPC: D01B3/08
Filed: 1956-04-05
Abstract: <PICT:0810134/IV (c)/1> <PICT:0810134/IV (c)/2> Apparatus for purifying wool, particularly raw wool, comprises a processing bath 1 containing mineral oil, a vessel 3 therein which has a perforated bottom 4 and is vibrated by a rotatable eccentric weight 8, and an apparatus 9 which supplies wool in an oil suspension to the bed 4, the wool being caused by the vibrations to move along the bed 4 and pass beneath oil spray pipes 10, 11, 12, the oil being re-circulated to the sprays so that purer oil is supplied to the spray 12 than to the others.  In a complete plant the bath 1 is divided into compartments 1a and 1b by a partition 20.  From the compartment 1a an outlet 21 conveys oil via a pump 22 and conduit 23 to the wool feed apparatus 9.  Oil is also drawn off from a branch conduit 24, and is then passed through a straining, centrifugally separating and collecting system 24-37 to a conduit 39 and spray series 41.  Oil is also passed via a second conduit 40 to another centrifugal separator 42, collecting vessel 44, and distillation column 48 to a tank 50 which supplies an even finer purified oil to a tank 57 and a spray series 60. From the part 1b of the bath 1 sprays 53 are supplied via conduit 52 with lower purity oil.  The wool discharged from the bed 4 is passed by a conveyer 54 to pressing rollers 55, and to a conveyer 65 which drops it into a centrifuge 66 where surplus oil is removed and pumped back to tank 57 which also receives oil pressed out by the rollers 55.  Level regulators 61 and 63 in the tanks 1 and 57 respectively regulate the oil levels in these tanks and the flow of oil through the sprays 60, and the level in tank 57 is maintained by a supply conduit 62, the system being topped up with pure oil through a conduit 64 via the tank 50.  In a modification, Fig. 3 (not shown), the conduit 23 leads to a mixing vessel into which wool is also fed down, the suspension being fed by a pump to the bath 1.  Two pairs of pressing rollers 55 are also provided, between which pairs pure oil is supplied from the conduit 62.  If desired a series of baths 1 may be employed, or the bed may be constituted by a perforated belt conveyer which is subjected to vibrations at right angles to the belt surface.  Specification 668,467, [Group III], is referred to.

Title: Improvements relating to the drying of continuous webs, and particularly of paper inpaper-making machines
IPC: D21F5/02
Filed: 1945-04-27
Abstract: 597,653. Drying materials in long lengths. CELLULOSE DU PIN. April 27, 1945, No. 10628. Convention date, June 16, 1944. [Class 34 (i)] In drying a continuous web of material, e.g., paper from a paper making machine, the paper is traversed around a cylinder 1 enclosed partly by an air-tight hood 2 into which air at a temperature of about 125'C, from a heater 3 is blown and vapour-saturated air at 80‹C. is withdrawn, through an orifice 4, by a fan 6, this withdrawn air being recirculated through the heater 3 and hood 2 after passage through two heat-exchangers 5a, 5b. In the latter supplied water is converted into steam at temperatures of 60‹C. and 40‹C. respectively, the temperature of the circulating air falling to 60‹C, and this steam is compressed to 90'C. by thermo-compressors 7a, 7b and then injected into other, e.g., pre-drying, cylinders 8 which operate under a light vacuum through a condensate extraction pump 9. Preferably the water supplied to the heat exchangers is the condensate from the drying air. In a modification a number of such cylinders 1 are totally enclosed by a hood having a plurality of hot-air inlet and vapour-saturated air outlet orifices, with the air being exhausted, as before, through heat-exchangers for generating a steam supply to pre-drying cylinders. In addition final drying cylinders are provided, these latter being located in the open and the hot air rising therefrom being collected within an upper open hood and directed to below the pre-drying cylinders.

Title: Machine for straightening wire-like leads of electric compo nents or other workpieces
IPC: H05K13/02
Filed: 1974-03-09
Abstract: 1462272 Straightening by axial rolling J F KOPCZYNSKI 9 March 1974 10653/74 Heading B3M [Also in Division B8] A machine for straightening the leads 29 (Fig. 1A) extending from a workpiece 30 (e.g. a diode or resistor), includes roll assemblies 60, 61 62 (Fig. 8) between which the leads are rolled without changing their cross-section, and conveyers for feeding workpieces to and from the assemblies. The workpieces are fed from a hopper 14 (Fig. 1) to a feed wheel 15 which feeds them to the work gap between the roll assemblies, and then to a conveyer 17. The workpieces are then wrapped in a packaging unit 18 and wound in strip form on a spool 190. In one embodiment, Fig. 8, the workpieces are transversely aligned in the hopper by its magnetic side walls, and are picked up centrally by magnets on the feed wheel 15. The wheel is rotated intermittently by a Geneva mechanism, and the roll assembly 62 is similarly intermittently raised (by an eccentric drive, Fig. 2, not shown) to the dotted position to allow a workpiece to be placed between the roll assemblies. The assembly 61 is moved slightly towards the assembly 60 during rolling, and then retracted to permit the wheel to remove the workpiece. A sponge-like wheel 53 prevents two workpieces from being rolled. The straightened workpieces are carried away on toothed belts 173 which are fed stepwise in synchronism with the wheel 15. The roll assemblies (Fig. 7) are of similar finned construction, with the assembly 62 being interleaved with the other assemblies during rolling. The fins are of plastics material. During rolling, the workpieces are tested for continuity by passing a current through them using brushes 155 (Fig. 7) which co-operate with metal fins at the opposite ends of the assembly 61. If a faulty workpiece is indicated, a relatively strong magnet 165 (Fig. 8) is raised to remove it from the wheel 15. A photocell unit 174, 175 senses the absence of the workpiece, and momentarily stops the conveyer 173. The finished workpieces are lifted from the conveyer 173 by adhesive tape 179 (Fig. 1), are enclosed by a second adhesive tape 187, and are fed as a composite strip to a spool 190, a liner tape 193 being interleaved between adjacent layers. In a second embodiment, (Figs. 9-15, not shown), the upper roll assembly is replaced by a series of cams, and the intermittent drive of the feeding assemblies is substituted by a continuous one in which the parts have cyclically increasing and decreasing speeds.

Title: Method of operating a direct-current transmission system
IPC: H02J3/36
Filed: 1975-03-14
Abstract: 1493495 HVDC power transmission ASEA AB 14 March 1975 [15 March 1974] 10671/75 Heading H2F In a method of operating a bi-polar direct current transmission system comprising bipolar converter stations 1, 2 having earthed centre taps and connected by two transmission lines 3, 4 and in the event of required disconnection of one pole, the corresponding transmission line is used as a return conductor for the remaining pole by increasing or decreasing the current in that conductor to the same value as in the pole in operation and opening the earth connection at one of the stations when the earth current is substantially zero. As described, if it is necessary to disconnect e.g. converter 7 because of a fault, by-pass switch 11 is closed. If station 2 is a rectifying station this will increase current in pole A whereas if station 2 is an inverting station, the current in pole A will decrease. In both cases the control of station 9 will reduce the voltage of this station to a low value corresponding to the preset current in line 3 since this current value is usually set at equal value in both poles, the earth connections will be currentless (as indicated by transductor 13) so that breaker 5 or 6 can be opened. After this, the by-pass switch 12 is closed so that pole B obtains a return conductor formed of items 11, 3 and 12. The degradation in power factor may be reduced by operating part of converter 9 as a rectifier and part as an inverter as described in Specification 1,329,764. This is facilitated by use of a plurality of series connected bridges for each converter, each bridge having its individual by-pass switch 12. The current in the remaining inverter may be varied so that the earth current exhibits distinct zero passages during which the breaker 5 or 6 may be opened. In Fig. 2 (not shown) station 1 feeds three stations connected in series, the junction between two of said stations being earthed via a breaker.

Title: Improvements in and relating to pressure controlled regulating devices, particularlyadapted for regulating combustion in furnaces
IPC: F23N3/02
Filed: 1925-04-27
Abstract: 248,310. Cash Co., A. W., (Assignees of Terry, C. M.). Feb. 4, 1925, [Convention date]. Machines and apparatus.-In a regulating device of the kind in which the fuel supply and draught of a steam-boiler furnace are regulated in accordance with the demand for steam on the boiler, the pressure of the boiler is transmitted to one side of a diaphragm 26, Fig. 1, loaded on the other side by a spring 27 and compensating spring 28 the tension of which is adjusted by a differential rack and pinion gear operated by a piston 65 actuated by water, oil or other fluid under pressure, controlled by the boiler pressure, and serving to actuate through the rod 13 the furnace dampers or a valve admitting steam to a motor controlling the speed of a mechanical stoker. Should the steam pressure in the boiler increase above the normal, the diaphragm 26 is deflected and the spindle 31 moved downwardly to open a spring-loaded valve 34 and admit pressure fluid from a conduit 41 through a conduit 46 to the space above a piston 48 resting on top of a double piston valve 50. The valve 50 is moved downwardly against a spring 53 and uncovers a port 64 so as to permit fluid to pass from below the piston 65 through the pipe 60 to the valve casing 36, and drain pipe 56, while the lower part of the valve 50 uncovers a port to allow pressure fluid from the conduit 41 and port 66 to pass to the pipe 62 and above the piston 65. The latter moves downwardly and serves to close the damper and reduce the fuel supply. The piston rod 13 carries a bracket 73 having arms 76 in which are mounted two gear wheels 77, 78 engaging with a fixed rack 70 and vertically movable rack 72 having teeth of the same shape and size. The wheel 78 has less teeth, preferably two, than the wheel 77. Downward movement of the piston rod 13 causes a slight downward movement of the rack 72 which movement is communicated through a lever 79 to the lower end of a sleeve 82 carrying the compensating spring 28. In order to control the apparatus by hand, a plunger 90 is lowered by rack and pinion gear 91, 92 operated by a hand lever 96 so as to close the conduit 46 and allow the piston valve to operate under the control of the spring 53 or the plunger 90. Pressure fluid is allowed to drain away from above the piston 48 through a small orifice 55.
