Patent GB-1046852-A (GB)
Title: Improvements relating to electrical measuring or indicating instruments
IPC: G01R25/00
Filed: 1961-12-13
Abstract: 1,046,852. Dynamo-electric machines. C. R. COOKE. Feb. 12, 1963 [Dec. 13, 1961], No. 44691/61. Heading H2A. [Also in Division G1] A phase difference meter comprises a plain annular stator having at least one set of polyphase windings thereon, each phase winding being distributed round the stator and arranged, when excited, to produce a leakage flux to form at least one pair of poles, and a rotor having at least one pair of vanes which cooperate with the poles, and a rotor winding for polarizing the vanes. As shown, Fig. 3, a phase meter comprises a stator core 1 which is a plain ring of laminated " Mumetal " (Registered Trade Mark), a rotor comprising two laminated Mumetal discs 4, 5 each having a vane 7 extending radially from its periphery, mounted on a pivoted spindle 6, and a rotor polarizing coil 9 wound on a bobbin 10 of Mumetal, which may alternatively form part of spindle 6. The stator core 1 carries a two-pole winding (as depicted in Fig. 1a or Fig. 2, not shown) for each phase of two three-phase sources; when the sources are connected to their respective windings they produce two contra-rotating magnetic fields the resultant of which is an alternating field whose angular alignment depends upon the phase relationship of the two sources. The rotor winding 9 is supplied with single-phase A.C. and the rotor vanes 7 line up with the stator field, a pointer 8 on. spindle 6 co-operating with a circular scale (not shown) to indicate phase angle; in addition, displacement of the rotor may be arranged to produce signals to control, e.g. the positioning of a machine tool. Each stator winding may alternatively be wound to produce four or more poles, e.g., as depicted in Fig. 1b (not shown). To prevent the polarizing current becoming 90 degrees out of phase with the stator field, with consequent loss of torque, the polarizing current may be derived from a transformer designed to deliver current in phase with the resultant of two polyphase sources; alternatively the rotor may include an induction member. To indicate the phase relationship between a single-phase source and one polyphase source or the resultant of two polyphase sources the former is connected to the polarizing winding while the polyphase source(s) produce(s) a rotating field in the stator; the rotor aligns itself with the stator field at moments of maximum rotor field strength. Drag may be offset by mounting on the rotor a small conductive ring or vane which coacts with a subsidiary polyphase stator winding to produce a countertorque, and the movement may be damped by arranging that the conductive element rotates in a permanent field. Errors due to magnetic drag and friction may be reduced by adding subsidiary stator windings presenting more poles than the main stator windings. Moreover the rotor vanes may be widened, or their number increased. If sources of unequal frequency are compared, the rotor will rotate at a speed which is a function of the frequency difference.

Title: Oxymethylene copolymers
IPC: C08G2/00
Filed: 1963-11-13
Abstract: Solid thermoplastic oxymethylene polymers, the molecules of which consist of chains of oxymethylene groups having distributed along the chains divalent groups containing adjacent carbon atoms forming links in the chains, 0.1 to 15% of all the groups forming the chains being said groups containing adjacent carbon atoms, are obtained by reacting in an inert organic formaldehyde solvent and in the presence of a cationic catalyst, formaldehyde and a prepolymer containing oxymethylene groups and other groups containing adjacent carbon atoms forming links in the chain in the proportion of 1 to 8 oxymethylene groups to each 2 of said other groups.  The process is preferably carried out by introducing formaldehyde and a cyclic ether into an inert organic liquid which is a solvent for both monomers in the presence of boron trifluoride or a co-ordination complex thereof and thereafter introducing further formaldehyde into the mixture. Copolymers of formaldehyde and ethylene oxide are exemplified.

Abstract: 1,003,771. Inspecting fabrics. AMERICAN CLOTH-STRAIT CO. Dec. 22, 1961 [Dec. 22, 1960], No. 45981/61. Heading D1S. [Also in Divisions G1 and G3] A misalignment of the weft threads with respect to the warp threads in a strip of woven fabric 16 travelling in the direction of the warp threads, is detected by causing two beams of light directed throuth the fabric 16 to traverse synchronously and repeatedly two respective short equal linear paths along the plane of the fabric, the paths being inclined to the direction of travel and to each other and spaced in the direction of travel, causing the beams to energize respective light sensitive devices to provide two signals indicative respectively of the number of weft threads which traverse each path within the same interval of time. The fabric 16 passes from a processing centre to a weft correction assembly 18, passes a weft sensing station 20 and then passes further processing stations 19. The fabric 16 at the assembly 18 passes around an idler roll 120, a skew roller 116, an idler roll 122, a bow roller 104, an idler roll 124, a skew roller 118, an idler roll 126, a bow roller 106, and an idler roll 128.
