Sept. 14, 1931, No. 25683. [Class 120 (ii).] Spindle reversing apparatus for ring spinning and doubling frames comprises a positioning bush or a pair of positioning bushes with peripheral portions, which occupy an angular position in relation to the bore of the bush, to facilitate the change of direction of the spindle driving belt from twist way to weft way or vice versa. A grooved shaft B carries a bush A, with inclined cylindrical surfaces A<1>, A<2> for each jockey pulley, the bushes being secured to the shaft by screws A<9>. Projecting snugs A3, A4 are provided on the bushes to engage in a slot c, Fig. 7, in the half-bearing C of the oscillating bracket D carrying the jockey pulley E. According to which snug the slot c engages and hence on which inclined portion the jockey pulley unit rests, the jockey pulley is inclined to lead the driving tape F twist or weft way. The portion a of the bush is slightly lower than the portion a<1> so that a side inclination is given to the jockey pulley to keep it clear of the driving tape. A modified form for narrow gauge frame comprises a single bush with an outer surface suitably inclined to its bore which is rotated through 180‹ to alter the inclination of the operative surface and hence of the jockey pulley. This bracket is secured to the shaft by screws passing through oppositely positioned snugs to engage the shaft. In frames of very wide gauge two single bushes of this type, one turned one way and one the other, may be employed for each jockey pulley. If desired, the shaft carrying the inclined bushes may be turned through 180‹ instead of each bush being separately turned. Specification 312,772, [Class 120 (ii), Spinning, twisting, &c.], is referred to.

Abstract: 822,275. Waveguide accessories. GENERAL ELECTRIC CO. Ltd., COLE, W. P., and WALSH, A. S. Nov. 25, 1957 [Aug. 23, 1956], No. 25856/56. Class 40 (8). A screen of polytetrafluorethylene is mounted in a waveguide to prevent radiation of ultraviolet light from a pre-TR tube. Such radiation causes ionization of air in the waveguide. The arrangement shown is a duplexer and consists of two waveguides 1, 2 coupled by long slots 4, 5 arranged in a common wall 3. Branches 6, 7 are connected respectively to a receiver and an aerial and branches 8, 9 to a matched load and a transmitter. The pre-TR tube is of the kind which emits ultra-violet light and is in the form of a quartz tube 13 passing through both waveguides 1, 2. Loss of energy is prevented by annular chokes 14. Polytetrafluorethylene screens 16 are arranged adjacent the tube on the high-power side. The capacitative reactance of the screens may be compensated by inductive loading in the form of two metal rods 17, Fig. 2, which pass through the screens 16 and are attached to square-section metallic strips 18 abutting the edges of the screens. These strips lie in recesses in the waveguide walls. Alternatively, the inductive loading may be in the form of conductive irises which may also fit into recesses in the walls or may be brazed to the walls. For narrow-band operation, the screen may have a thickness equal to an odd number of quarter wavelengths, no inductive loading being necessary. The surfaces of the screens may be treated with a solution of sodium or potassium in liquid anhydrous ammonia. The waveguides may be formed from two identical channel members which join at a plane bisecting the broader walls, means (not shown) being provided to clamp them together. Specification 822,274 is referred to.

Abstract: 728,376. Disc brakes. GIRLING, Ltd. Oct. 12, 1953 [Oct. 16, 1952], No. 25938/52. Class 103 (1). In a "spot-type" disc brake, friction pads adapted to engage opposite faces of a rotatable brake disc are mounted in a bore in a block which is slidable in a direction parallel to the axis of the disc in a stationary housing and one pad is urged towards the disc relative to the block by hydraulic or mechanical means and the other pad is backed by an abutment member mounted in an open end of the bore so that when the first pad is moved into ongagement with one face of the disc. the reaction on the block moves the block axially to urge the second pad into engagement with the other face of the disc. Fig. 1 shows an embodiment of the invention in which a brake housing 10, secured to a rigid plate 15, houses three pairs of opposed hydraulic cylinders 11, 12, 13 for normal braking and on an extension of the housing 10 is formed a slidable block 16 in which is formed a bore 17 housing mechanically actuated friction pads for parking. Fig. 2, which is a section on the line 2-2 of Fig. 1, illustrate, the mechanically actuated brake. When a pull is applied to the free end of the lever 21, it is rocked about its pivot 22 and tappet 26 urges friction pad 19 into engagement with one face of the brake disc 14. The reaction of the lever on the block 16 moves the block axially to urge the other friction pad 18, engaged by a plug 27 which forms an abutment into engagement with the opposite face of the disc and the pressures exerted by the two friction pads are balanced. The axial movement of the block 16 is limited by a lug 31 which defines the axial position of the block when the brake is in its "off" position. A stud 24 is provided for adjusting the wear of the friction pad. Another form of extension is illustrated which is wholly hydraulic in operation and an alternative form is described which combines both hydraulic and mechanical operation of the parking brake extension. Specifications 688,382 and 700,644 are referred to.
