Patent GB-607595-A (GB)
Title: Improvements in or relating to band or hose clips
IPC: F16L33/08
Filed: 1945-03-15
Abstract: 607,595. Band Clips. O'SHEI, W. E. March 15, 1945, Nos. 6468, 7486, 16869 and 34246. [Class 44] The part-threads on the bands of band or hose clips of the kind having a worm or screw engaging the band to tighten it, are produced by a press-like operation by the use of dies which force the material of the band at those parts where the serrations are to be produced in a direction towards one side of a plane through opposite ends of each part thread, and in a direction towards the other side of the plane at the intermediate parts where the teeth are to be produced. The part-threads or serrations 15, Figs. 2 and 4, of a band clip, for example, of the kind described in Specification 602,458, are produced by a pressing, embossing, drawing or like operation between dies or punches 18, 19, Fig. 6, which are preferably of cylindrical form having a series of annular or helical grooves corresponding to the thread to be produced, the grooves of one die being arranged opposite the ridges of the other, producing the form of serration shown in Fig. 5. The dies are preferably of greater diameter than the screw 9 to be used in the clip. Dies with helical grooves are used to produce partthreads of which the helix angle is less than that of the screw, as described in Specification 607,671. To produce bands with a thread of helical angle approximating -to that of the screw while still using large diameter dies, multiple start threads may be used on the dies. To avoid breakage of the dies due to overhang at the end of the thread if the latter is carried to the extreme end of the band, the thread is stopped short of the end, as shown in Fig. 4, and the width of the thread decreases towards the end, or preferably towards each end. The centre line of the threads is preferably offset from the centre line of the band so that the teeth assume a position in alignment with the screw as it is tightened, the clearance of the band in the screw housing allowing slight lateral movement. As shown in Fig. 3, the surface of that part of the clip which underlies the threaded part may be formed or recessed to accommodate the projections thereon, for example, the plain end 3 of the band and the part 2 of the housing may be curved, or spacers may be provided. Alternatively, the projections on the underside of the threaded part may be ground or sheared off, or the material of the projections 16a, Fig. 5, may be forced into the adjoining spaces 17a to make the underside of the band flat. Specification 542,482 also is referred to.

Title: Improvements in traffic control signals
IPC: G08G1/096
Filed: 1941-05-20
Abstract: 545,347. Road-traffic signals. LANGLEY, F. A. May 20, 1941, No. 6472. [Class 118 (ii)] A traffic control signal comprises an opaque disc which is rotated in front of an illuminated disc divided into two or more coloured sections, and is provided with an aperture through which the coloured sections of the inner disc are seen in succession. The device may comprise two circular casings 10, 11, Fig. 1, mounted on a standard 12 and each provided in opposite faces with an opaque disc 13 having an aperture 14 near its edge. The discs are rotated by suitable gearing from a shaft 19, Fig. 2, driven by a motor 21, the gearing being so arranged that all the apertures cover and uncover a signal simultaneously. Behind and parallel with each disc 13 is a stationary disc or annular frame 28, Figs. 2 and 8, formed of arcuate sections 29, 30 of translucent coloured material. An electric lamp 41 carried by a frame 42 is arranged behind the disc 28 and in line with the aperture 14 and revolves with the disc 13. The illuminated coloured sections are seen through the apertures 14, and the position of an aperture indicates the time remaining before a change of colour occurs. The sections 29, Fig. 8, may be coloured green and the sections 30 red, but yellow sections may be arranged between them. Alternatively, sections of colourless material may be included over which a semi-circular frame 51 having red and green sections, can be moved. By adjusting the position of the frame, the relation between the periods during which red and green signals are exposed can be adjusted to suit the volume of traffic.

Holes 23 in one end of the bands adapted to engage a peg 24 allow of adjustment to fit various sizes of rim. Fig. 7 shows a modified form adapted to be passed through a slot in the rim and contained therein. This form comprises a metal cover 32, walls 33, and bridge pieces 36 to hold the heating wires in place. British Specifications 24049/14, and 248,852, [both in Class 39 (iii)], and 425,360, [Group XXIV], and U.S.A. Specification 1,830,221 are referred to.

In a screw-and-nut mechanism employing recirculating balls, the return passage for the balls is formed in a two-part insert member 15 secured in the wall of the nut and having a pair of lugs 17, 18 projecting into the screw groove, the ends of each lug being shaped to provide a throat directing the balls into and out of an oblique passage 21 in the insert, and the insert being divided, along the axis of the transfer passage, into two identical parts. The two lugs 17, 18 are spaced by a distance more than one and a half turns, but less than two turns, or by a distance in excess thereof by any multiple of a whole number. The insert 15 is bolted into a recess milled in the nut 12, and is externally shaped to conform with the periphery of the nut so that the passage 21 lies within the thickness of the wall of the nut.

Abstract: 1,190,324. Coating apparatus. MEAD CORP. 13 Feb., 1968 [13 Feb., 1967], No. 7117/68. Hearing D1L. Coating apparatus comprises a stationary member having a curved surface provided with a longitudinal cavity creating a fluid-holding pocket on said surface under a web fed thereover, means for introducing coating fluid to said cavity, and means for removing excess coating fluid from said cavity. As shown, a fixed cylindrical tubular member 11 is provided with a fixed internal partition 22, and liquid coating medium, delivered under pressure through an opening 23 to one interior chamber 20 thus formed, passes to the outer surface of member 11 via a line of apertures 13. A line of apertures 14 connects the outer surface of member 11 with the other internal chamber 21. A web 10 passes over apertures 14, 15 and over a wire-wound driven roller 12 journalled at 'the surface of member 11 on the outer side of the apertures 13. Web 10 is biased against the .surfaces of member 11 and roller 12 by a leaf spring 26. The coating medium issuing from apertures 13 forms a pocket 15 of liquid between roller 12, the -outer surface of member 11, and the 'under surface of web 10 travelling towards roller 12. The web thus coated passes over the latter and the excess liquid passes through apertures 14 into chamber 21, to escape therefrom, for re-circulation, through an opening 24. The web initially passes over a roller 29 carried' by an arm 34 axially adjustable for varying the angle of approach of web 10 to member 11, In a modification apertures 13 are replaced by a continuous slot; the width of which may be varied by turning a screw connecting the outer wall of chamber 20 diametrically with portion 22. In a further modification, roller 12 is replaced by a fixed ridge.
