Title: An improved process and apparatus for impregnating insulating dielectric materials
IPC: H01B13/30
Filed: 1928-03-20
Abstract: 313,987. General Engineering Co. (Radcliffe), Ltd., and Taylor, S. March 20,1928. Impregnating-compositions for electric insulation. - In a process for impregnating dielectric insulating materials, for example the coverings of electric cables, with oil, the oil and the material are separately treated under vacuum to remove air and moisture therefrom, the oil is admitted under vacuum to a chamber containing the material, and is kept under vacuum or isolated from the atmosphere during the impregnation process. The surplus oil is removed after the impregnation process and stored in a vacuum for further use. The apparatus comprises chambers adapted to be used as impregnation chambers, or as chambers for de-aerating the oil, for example, by spraying under vacuum, with means for transferring the oil from one chamber to another. The oil is first prepared in a mixing tank a, which is connected by a pipe b<1> to a vacuum tank c provided with mechanical stirring means. The tank c is connected to the main vacuum pipe d which leads to a vacuum pump and a condenser; and from the bottom of the tank c is a connection to a pump e, the output of which is connected to a floatcontrolled valve f in the de-aerating chamber g, with branch connections through a relief valve e<4> to the tank c, and through a valve e<6> to a pipe o. In the chamber g is a spray device f<1> through which the oil is sprayed, and at the top of the chamber is a catch pot g<1> connected by a valve g<2> to the vacuum main. From the bottom of the chamber g oil is forced by a pump h into a chamber k provided with stirring means. A connection from this chamber leads to a vacuum and pressure pump k<2> having a reversible motor and a bye-pass valve k<3>. From the pump k<2> connection is made through a valve to the impregnating tank m, with branch connections to the tank k and to the pipe o. The impregnating tank is also connected to the vacuum main. All the tanks are jackettecl and connected to a heat exchange oil circulating system to control the temperature. Oil mixed and melted in the tank a is transferred to the tank c and mixed under vacuum. It is then sprayed into the tank g, and transferred to the storage tank k. The cable to be treated is subjected to vacuum in the tank m till it is dried and de-aerated. Oil is then pumped in from the tank k, the valve m<1> may then be closed, and pressure applied by means of the supply pump k<2>. When the treatment is complete, the oil may be returned to the tank c or to the de-aerating tank g for further de-aeration. For certain purposes the tanks k and m only may be used, the oil being sprayed in the tank m and stored in the tank k. Alternatively, the tank a may be omitted. The impregnating medium may be oil and resin or similar mixtures.

Patent GB-398884-A (GB)
Title: Improvements in or relating to winding machines for yarn, thread or the like
IPC: B65H54/14
Filed: 1932-03-23
Abstract: 398,884. Bunch-winding mechanism for yarn and like winding machines. UNIVERSAL WINDING CO., 95, South Street, Boston, U.S.A. March 23, 1932, No. 8708. Convention date, Aug. 13, 1931. [Class 120 (ii).] In yarn and like winding machines a bunch is wound before the engagement of the yarn by the guide which effects the service winding, whereby undue friction and tensioning of the yarn is avoided during the winding of the bunch. An arm 26 is so arranged that it engages the yarn as shown in Fig. 1 to wind the bunch b and hold it clear of the traverse guide 12, and at the conclusion of such winding it is automatically moved to the position shown in Fig. 2 so as to bring the yarn into the path of the traverse guide which thereupon engages it and the normal service winding takes place. The arm 26 is adjustably secured to a lever 32 carrying a lever 40 which is coupled to the traverse bar 11 and oscillated thereby, so that, by means of a pawl 42 and a ratchet wheel 35, a cam 45 is rotated until a recessed part 46 thereof by engagement with an extension 37 of the lever 32 permits a spring 47 to move the lever into the inoperative position. A pawl 34 carried bv the lever 32 serves as a check for the ratchet wheel 35 and, by its engagement with a finger 35<1>, retains the ratchet wheel in its initial position. To reset the mechanism the lever 32 is moved in a clockwise direction so that the extension 37 is moved from the cam and engages a finger 34<1> on the pawl 34 to remove it from the ratchet wheel which is returned to its initial position by a helical spring. Specifications 15338/13, 293,437, [both in Class 120 (ii), Spinning, twisting, &c.], and 367,726 are referred to.

Patent GB-565959-A (GB)
Title: Improvements in or relating to electrical gauging arrangements
Filed: 1943-06-01
Abstract: 565,959. Gauges. STANDARD TELEPHONES & CABLES, Ltd., and BISHOP, H. S. June 1, 1943, No. 8737. [Class 106 (ii)] [Also in Group XXXVI] An electrical arrangement for comparing physical dimension of an article with a standard physical dimension comprises two spark gaps, means for setting the lengths of the said gaps respectively in accordance with the said dimensions, means for applying a sparking voltage simultaneously to the said gaps, and means for indicating the particular gap across which the spark occurs. Fig. 1 shows an arrangement for determining whether a linear dimension of a test-piece, such as the thickness of a disc, is between specified limits. A spark gap G2 is adjusted by a jig so as to correspond to the thickness of the piece under test, but to vary in the opposite sense while spark-gaps G1 and G3 are preset to correspond to the maximum and minimum permissible limits of the thickness of the test-piece. Thus, gap G1 is smaller than gap G3. The lower electrodes of the spark gaps are connected respectively to the trigger electrodes of cold-cathode discharge tubes V1, V2, V3, the anodes of which are connected through respective relays A, B, C to HT+. An induction coil I is arranged to supply a high voltage to a variable tap Q on a potentiometer Z. The tap Q is connected to the upper electrodes of spark-gap G2 and can be connected to the upper electrodes of spark gaps G1, G3 through change-over contact a1 operated by relay A. The primary of the induction coil I is energized from a voltage source E through key K and contact a2 operated by relay A. A test is made by inserting the test-piece to set gap G2. Key K is depressed to break the primary circuit momentarily and hence apply a high voltage across gaps G1 and G2. If the piece is larger than the permissible upper limit, gap G2 is smaller than G1. Then the spark will occur across G2 and relay B will operate to indicate the fact. If the piece is within or below the permissible limits, the spark will occur at Gland relay A will operate. This causes contact a1 to connect the applied voltage across gap G3 and causes contact a2 to open to give another voltage impulse. Then if the piece is within the limits, the spark will occur at G2 to operate relay B, while if the piece is below the lower limit, relay C will be operated. A contact d opens the H.T. circuit at the end of a test. The relays A, B, C may operate means for automatically sorting the pieces according to size. In a modification, Fig. 3 (not shown), only two valves are used, the valve V1 being automatically switched into the position of valve V3 by the operation of relay A. Also the high potential is generated by charging a number of condensers in parallel from a battery and discharging them in series through a resistance.

Title: Method and apparatus for processing heat-softened mineral material into filaments
IPC: C03B37/02
Filed: 1965-03-02
Abstract: A method of processing glass into filaments comprises the steps of establishing a supply of glass in a feeder, flowing streams of the material through orifices in the feeder floor and attenuating the streams, as they cool, into filaments, wherein the orifices are arranged in spaced groups and excess heat is conducted away from a region of the feeder floor between the spaced groups to assist the establishment and maintenance of uniform distribution of temperature of the glass in all the orifices and wherein the feeder floor is supported between adjacent groups or orifices within the said region from which heat is conducted to prevent sagging of the feeder.  Glass is fed into a feeder having walls 46, 48 (Figs. 3 and 5, not shown), and floor 56 made of a platinum-rhodium alloy.  The floor 56 comprises four prefabricated sections 61-64 containing orifices 68 through which the glass flows.  The sections 61-64 are welded together along their edges, the longitudinal central join being indented upwardly 76 (Fig. 6, not shown).  Along this join in the indent 76 is an oval-shaped hollow tubular support member 80 which is separated from actual contact with the feeder floor by a layer 78 of heat-resistant electrically insulating material.  The support 80 is so fixed that it leaves the feeder floor visible from below whilst giving sufficient support to prevent warpage.  Water is flowed through the support member 80 to conduct excess heat away from the central region.  An additional transverse support member 91 is fitted at the central point of all the joins. Further cooling tubes 94 are fitted out of contact with the feeder floor down its outer edges. These also have a series of fins 96 which extend inwardly between successive or alternate rows of nozzles 66 to control the viscosity of the glass therein.  Alternatively, the feeder floor may be flat and not indented along the central join or the insulating layer 78 may completely surround the support tube 80 (see Figs. 8, 9, not shown).  In an alternative embodiment (Figs. 10, 11, not shown), the feeder floor comprises eight prefabricated sections there being hollow support and cooling tubes along the three longitudinal junctions, and the transverse cooling fins are attached to the two outer tubes.  The glass is flowed through the orifices 68 and is attenuated and sized in a conventional way.
