Title: Improvements in and relating to coil-winding machines
Inventor: ORAM JOHN ANDERSON
IPC: H01F41/06
Filed: 1954-02-16
Abstract: 764,697. Coiling wire on potentiometer cards. AIR TRAINERS, Ltd. Feb. 16, 1955 [Feb. 16, 1954], No. 4526/54. Classes 83 (2) and 83 (4). [Also in Group VIII] A machine for winding a coil of wire on a card comprises an annular head mounted for rotation around the card and means for effecting relative movement between the head and the card along the length of the card, the head carrying a notching tool for cutting notches in an edge of the card and a supply of wire which, as the head rotates, is payed out over a guide so disposed on the annular head relatively to the notching tool that the wire is received by a notch almost immediately after the notch is formed. A potentiometer card 44 to be wound is held at its ends by clamps 100, 102 so as to extend through an annular rotary winding head 28. The clamps 100, 102 are carried by a rigid rectangular frame 105, 104, 107 connected by parallel linkage means 114, 116 to a slide 42 on a support 36, which support is moved along the machine by a driven screw 16 to move the card 44 axially through the winding head 28. In its passage through the winding head 28 the card 44 is guided by co-operating jaw members 90, 92, the jaw 90 being lightly spring-urged against the jaw 92 and the card 44 is urged so that the edge to be notched bears against a vertical part 99 of the jaw 92 by a weight 108 pulling on the clamp 102 to tend to align the parallel links 114, 116 with the card. The winding head 28, rotated by a shaft 14, carries a supply of wire 66, a wire guide pulley 68 on a pivoted arm 70, a wire guide pulley 86 and, about 10 degrees in front of the pulley 86, an adjustable notching knife 48 which forms a V-notch in one edge of the card just before the wire is laid therein, the wire being guided also by shaped surfaces 124 on the jaws 90, 92. The pivoted arm 70 also carries a brake bearing on the wire supply 66 to maintain the wire tension constant. The notching knife 48 is adjustable, in a slot 52 in a support 54 on the winding head 28, to and from the card, to vary the depth of the notch cut, by an eccentric pin 60c, on a rotatable key 60, engaging a slot in the knife. The knife 48 is also adjustable to and from the face of the winding head 28 by a screw 58 bearing on the knife. A revolution counter 126 for the number of revolutions of the winding head is provided. A limit switch 130 is engaged by a projection 132 on the frame 104 to stop the machine when the required number of turns have been wound. The head 28 may be moved axially along a stationary card.

Abstract: 1,169,742. Transformers. PLESSEY CO. Ltd. 30 Jan., 1967 [2 Feb., 1966], No. 4526/66. Heading H1T. The windings of a transformer are wound on an insulating bobbin 7 which fits on to core parts 3, 4 of a magnetic pot core structure 1, 2, the secondary winding being wound before the primary and its high-voltage end lead being led out through an insulating sleeve 12 bonded in a passageway 10 formed in one of the end cheeks 9 of the bobbin. The insulated turns of the transformer are bonded together to form a solid mass, by, for example, drip impregnation with a polyester based resin impregnant which is polymerized by a heating current passed through the secondary winding. The bobbin may preferably have been compressed during winding, and released thereafter to produce spaces at the winding ends which, like the space around sleeve 12, are filled with the impregnant. The pot core structure is preferably sintered or moulded from ferrite material and has corner portions 5, 6 to define the inner cavity for containing the bobbin which may be moulded from glass-filled nylon.

Title: Process of and apparatus for washing or otherwise treating wool and other fibrous textile materials
IPC: D01B3/08
Filed: 1925-02-18
Abstract: 230,808. Duhamel, E. C., and Compagnie GÚnÚrale des Industries Textiles. March 11, 1924, [Convention date]. Passing loose fibrous materials through fluids and fluid-applying materials.-In washing wool or other textile materials or removing impurities from silk, the material is passed through a series of small vats the last of which contains clean washing- liquor and is passed between squeezing-rollers on leaving each vat, the expressed liquor being led to the previous vat. The expressed liquor may be centrifuged to remove its impurities and water may be added to cause the dirtiest liquor to give up some of the soap or other detergent which has been adsorbed by the impurities. The liquor is passed from vat to vat in the opposite direction to the passage of the material, and in apparatus having a double row of vats, the circulation of liquor may be in series, parallel, or series-parallel. The vats are just of sufficient capacity to wet the material, and liquor draining from the material before it reaches the squeezing- rollers is returned to the same vat. The overflow of each vat passes to the next dirtier vat. Fresh or centrifuged liquor is added to the first vat to maintain its volume. In apparatus for carrying out the process shown in Fig. 4, (Cancelled) wool in two parallel layers enters vats E and passes through a pair of vats B, to a larger vat A containing clean washing-liquor. Pressure rollers 6, 3, 2 are provided for compressing the liquor, and ducts controlled by float-valves lead the liquor back to the vats having the next dirtier liquid. In order to maintain the level of liquor in the middle vats B, a float-valve in one of those vats controls an electric motor to adjust the pressure of a squeezing-roller R thereby determining the volume of liquor expressed by the rolls 2 and returned to t.he middle vats B. Valves are provided to determine the flow of liquor in series, parallel, or series-parallel through the vats of the apparatus. A steam turbine may be employed to operate centrifuges, the waste steam being utilized for drying the washed material. The centrifuging may be performed in two operations, the first serving to remove the colloidal mud from the used liquor.

The limbs are 30-60 cms long, and have a cross section of 100-300 sq. cms. A second ionization chamber 23 may be provided to measure the source radiation directly for comparison at 32 with the radiation passed through the sheet. A cylindrical shield 20 around the source is adjustable by a knob 11 via gear 27, coupling 28 and shaft 29. The result of the comparison of the two detector signals is displayed at 9. The shield can be moved by knob 11 to initially zero the signal at 9. The knob 11 can be calibrated, and used to re-zero the meter when the sheet is present, the knob rotation measuring the density. Alternatively the knob may simply be marked to show whether the sheet is acceptable or not. Finally, the meter 9 can be calibrated in terms of density. In another embodiment, Fig. 2 (not shown), the shield and source are in the upper limb, and knob 11 is directly connected to the shield.
