[Class 39 (i).] A rectifier cooling system comprises a plurality of sections for cooling the circulating fluid and valves which automatically control the flow of the fluid through at least one of the sections in dependence on the temperature of, or the load on, the rectifier. The fluid passes through coolers 6, 7, Fig. 1, the first of which is permanently in circuit. The passage of fluid through the section 7 is controlled by a thermal responsive relay 10 through a valve 8. A fan 24 may be used to cool the section and is controlled by a thermal responsive means 11 which is adapted at a certain temperature of the rectifier to operate a switch 20, 21 by energizing a coil 18. A switch 19 may be used to short-circuit the coil 18 to connect the fan permanently in circuit. A relay 14 prevents operation of the fan until the load has reached a certain magnitude. In a modification, three cooling sections 27, 28, 29, Fig. 2, are provided, two thermal responsive means 30, 31 being adapted to operate the valves 34, 35 of the sections 28, 29 at different temperatures. Upon closure of the valve 34, contacts 36 are connected together to operate a switch 39 through a coil 40 to start the fan 42. Time delay means may be used to delay the starting of the fan until a predetermined time has elapsed after the connection of the contacts 36. In a further modification, a two-way valve is used to close the section 6, Fig. 1, when the section 7 is opened. The valves may be controlled by both thermal and load responsive means or one valve may be controlled in dependence upon temperature and the other in dependence upon the load. A section which is kept permanently in circuit may be located below or adjacent another section to prevent freezing of the medium in the latter. Thermostatic means may be arranged to determine whether the rectifier or the cooling fluid shall be heated, before the rectifier is started. A number of cooling sections may be connected in series, a temperature or load regulated valve being inserted in a byepass used with one or more of the sections.

Title: Improvements relating to hose cocks for use with apparatus for dispensing measured quantities of liquid
IPC: B67D7/48
Filed: 1938-04-25
Abstract: 510,281. Valves. AVERY-HARDOLL, Ltd. and FRASER, J. April 25, 1938, No. 12280. [Class 135] A hose cock for use with liquid measuring and dispensing apparatus, particularly of the flow meter type, incorporates a valve means subject to the control of the operator and to the influence of liquid pressure; when the valve means has been subjected to a control operation and opened by liquid pressure, the flow of liquid is caused to engender a venturi effect which is utilized to counteract the tendency of the valve means to interrupt delivery. As shown, a piston valve 2 slides in a cylindrical member 3a integral with a closure plug 3, and is normally closed.by a light spring 6 and by a stronger spring 7 interposed between the plug 3 and a flange 5a on a rod 5 slidable in the plug. The valve is relieved of the pressure of the spring 7 by manual operation of a lever 8 acting upon the rod 5, and can then be opened by liquid pressure. The -interior of the cylinder 3a is connected by passages 3b, 4b with openings 10a in a venturi tube 10 fixed in the delivery nozzle 4c, so that the flow of liquid through the venturi induces a suction in the cylinder 3a counteracting the closing force of the spring 6. The valve 2 may be replaced by two valves, one subject to the control of the operator and the other controlled by a spring such as 6 and the suction created in the venturi tube.

Patent GB-890110-A (GB)
Title: Improvements in and relating to methods of making stretch yarns
Inventor: STARKIE DAVID
IPC: D02G1/00
Filed: 1957-04-16
Abstract: A thermoplastic, e.g. polyamide, polyester or polyacrylonitrile, mono- or multi-filament yarn is crimped by continuously stretching and heating in such a manner that a temperature gradient is established across the stretched yarn, cooling and permitting the yarn to relax.  The gradient may extend between a high temperature at which the yarn will retain all the extension imparted to it by stretching and a low temperature at which it will be restored to its condition before stretching.  The gradient may be produced by heating the yarn on one side and cooling it on the other side as by passage through the nip of heated and cooled rollers moving in the same direction and at the same peripheral speed as the yarn.  As shown in Fig. 3, yarn 10 passes successively around rollers 11, 12, 13, 14, of which 13 is heated and may co-operate with a chilled auxiliary nip roller (not shown) and rollers 12, 13, 14 are rotated at a peripheral speed 10% greater than roller 11.  Subsidiary pulleys or guides (not shown) may be used at each roller to prevent yarn slipping and the yarn may pass over a portion only of the periphery of roller 13. As shown in Figs. 5-7, yarn 10 travels from a package 16, through tensioner 17, several times around grooved, stepped, conical stretching rollers 11 and 12, partially around grooved heating roller 13, several times around grooved drawing-off rollers 14 and 18, to take-off mechanism 19.  Roller 13 is heated by an insulated metal block 25, in which are embedded electrical heating elements, and the yarn is pressed in contact therewith by a disc 26 which is carried on a biased, pivoted arm 27 and chilled, e.g. by a flow of cold air thereon from the pneumatic system through which a piston and cylinder 28 may bias the disc towards roll 13.  A yarn-deflecting roller 29 is similarly mounted on a pivoted arm 30 and may also be <PICT:0890110/IV (a)/1> <PICT:0890110/IV (a)/2> <PICT:0890110/IV (a)/3> <PICT:0890110/IV (a)/4> biased by a spring or pneumatically. The pneumatic system for rollers 29 and 26 is controlled by a handle 33 rotating a cam 35 to operate a valve 32 and a key-operated valve 41.  These rollers are adjustably displaceable by eccentrics 37, 38, on the cam-shaft 34, to facilitate threading-up.  Specifications 796,876 and 808,213 are referred to.
