Title: Fashioned knitted fabric with cable stitch and method of and apparatus for making same on a full fashioned knitting machine
Inventor: BOUTILLETTE EDWARD JOSEPH
IPC: D04B11/00
Filed: 1965-11-08
Abstract: A method of knitting a cable stitch on a full fashioned machine using a single transfer point in which a loop intermediate two bands of wales is deposited on an adjacent needle, whereafter loops are successively moved to vacant needles to cross one band over the other.  In the preferred embodiment each band comprises two wales and the intermediate loop is transferred onto the first loop of the right hand band.  The loops of the left hand band are then successively transferred to the right onto the denuded needles.  The loops on the first needle of the right hand band are then transferred three spaces to the left onto the first, vacant needle.  The left hand band is again moved to the right, and the second loop of the right hand band transferred three spaces to the left.  The operation is concluded by again moving the left hand group to vacate the centre needle. Knitting is then recommenced for several courses before the next operation.  The lateral movements of the points is controlled by a slide 90 (Fig. 3, not shown) engaging the point bar 66 and abutting a pattern chain 116.  Before each loop transfer the point bar is cammed to the right and then returns under spring action until a stop 112 abuts a peg on the chain.  The height of the peg determines the position of the point over the needles.  The point is dipped to engage the loops in conventional manner.  A rotatable cam 106 engages pegs of different lengths on a member 98 fixed to the slide.  Cam 106 normally engages the centre pegs 102, and is rotated to engage either the high pegs 100 or the low pegs 104 to shift the point bar one space to the left or three spaces to the right respectively.

Title: Waveguides
IPC: H01P3/02
Filed: 1973-10-17
Abstract: 1490339 Waveguides NATIONAL RESEARCH DEVELOPMENT CORP 16 Oct 1974 [17 Oct 1973 28 June 1974] 48474/73 and 28836/74 Addition to 1392452 Heading H1W Electromagnetic waves are propagated in the dipole mode in a waveguide lacking an internal wave-supportive structure. The invention is a modification of that described in Specification 1,392,452 in which co-axial structures for the propagation of these modes are disclosed. The modes are designated EH n  and HE n  and the field pattern of the EH 1  mode in a circular waveguide is shown in Fig. 1. The dipole modes have an asymmetric E-field pattern and both H and E components in the direction of propagation. It is shown in the specification that these modes may be propagated with low attenuation, low dispersion and without frequency cut-off. Conditions for propagation are met if the bounding surface is anisotropic and, in particular, if the longitudinal impedance is resistive and inductive whilst the transverse impedance is resistive and capacitive. This condition is met in the construction shown in Fig. 2b by the provision of a number of parallel, longitudinal strip conductors 15 supported on the inner surface of a dielectric tube 16. The strips may be replaced by longitudinal wires embedded in the tube 16 and defining one or more concentric cylinders. Since the mid-plane intersecting the diametral electric line of force (Fig. 1) lies on an equipotential, a conductor may be inserted in this plane without disturbing the field pattern. The resultant semi-circular waveguide using a semi-dipole mode is described in the specification (Fig. 4, not shown). A rectangular waveguide for dipole-mode propagation may consist of parallel conductive plates 64, Fig. 7, arrays 65, 66 of parallel conductive strips 67 having the anisotropic impedance set forth above. The conductive members are supported by a rectangular dielectric tube 63. The wave may be launched by a probe 69 and has the configuration shown in Fig. 5b. Various constructions are described (Fig. 6, not shown) in which the arrays of strips 67 are replaced by parallel wires lying in one or more adjacent parallel planes. In the construction shown in Fig. 8, one narrow wall and both broad walls of the waveguide are provided by a conductive member 74 of U- section. The other narrow wall is replaced by a single conductor 76 or an array of such conductors lying in a plane normal to the limbs of member 74. Such conductor or conductors may be supported by a mass of material 75 of low dielectric constant which may occupy the whole of or any part of the space enclosed by the member 74. The conductor or conductors may be provided with a thick layer of dielectric, i.e. PTFE, which serves to reduce dispersion. The wave is launched by means of a probe 77. The specification also describes a resonator having cylindrical walls, constructed as shown in Fig. 2b, and end walls in the form of conductive discs (Fig. 3, not shown). One or more probes may extend radially into the resonator at the mid point.
