IPC: B65H69/04
Filed: 1968-01-16
Abstract: 1,149,708. Knotters. SHIMADZU SEISAKUSHO Ltd. 16 Jan., 1968 [17 Jan., 1967], No. 2363/68. Heading D1C. A knotter for tying a weavers knot comprises a rotary bill 17 and two pairs of guides 27a -b, 28a -b movable parallel to the bill axis for wrapping the two ends of yarn around the bill. The free ends of yarn are held pneumatically. A loop of yarn 24 is pulled by the guides under yarn 25, Fig. b, while the yarn is held by rotating the bill. Return of guides 27 to their starting position, Fig. c draws a loop of yarn 25. The bill is rotated 180 in the direction of arrow X, and clamps and cuts the free end of yarn 25. The bill is rotated through a further 180, the end of yarn 24 is clamped, and the loops of yarn pulled over the held end by moving arms 42, 44, 45 to a position between guides 27a, 28a. The knot is tightened by moving guide 28a, or an auxiliary guide (76 Figs. 2, 8 not shown), away from the bill; and the end of yarn cut between arms 44-5.

Abstract: 1445272 Fluid actuation of switches; switch contacts GAUER AG ELECTRONIC 18 Jan 1974 [26 Jan 1973] 02451/74 Heading H1N A pressure-actuated switch comprises a thin domed resilient element 11 (or 111, Figure 2, not shown) having a convex surface and being supported at its edge; a pressure-actuated member 9 (109) is movable relative to element 11(111) for exerting a mechanical force against the said convex surface via a confronting surface 9a (109a); either (Figure 1) the element 11 has a central region of insulating material 17 surrounded by conductive material 13, and the confronting surface 9a is completely formed of conductive material, or (Fig. 2, not shown) the element (111) has a completely conductive convex surface (113) and the central region of the confronting surface (109a) comprises insulation (110); the arrangement being such that, when actuated, the member 9 (109) deforms the element 11(111) and the respective conductive materials come into contact. The actuator may be mechanical, but as shown compressed air or hydraulic fluid acting in bellows 8 causes conductive member 9 to engage an annular conductive layer 13 on a spring steel disc 12. As conductive housing halves 1a and 1b are joined by an insulating ring 2 and bellows 8 are conductive, this closes a circuit between respective leads 3 and 4. Threaded member 16 serves toadjust the operating pressure, and ensures connection between the edge of layer 13 and the side walls of recess 15.

[Class 130.] The stem of a pipe is constructed of a metal such as aluminium having good heat-conducting properties. As shown in Fig. 2, a wooden or other bowl is screwed into an enlarged portion 13 of a metal stem 2, a metal disc 12 being fitted beneath the bowl which communicates with a chamber 4 through a passage in a screwed nipple 14. A central chamber 5 communicates with the chambers 4 and 8 through passages in members 15 and 9, respectively. The mouthpiece is screwed to the member 9. In the modified construction shown in Fig. 3, the chamber beneath the bowl consists of a spiral groove 20 which terminates in a passage 22 leading to a chamber 23. Extending throughout the full length of the stem the member 9 separates chambers 23, 25 which communicate with one another through passages, not shown. A further modification is shown in Fig. 6 in which smoke passes from the bowl 1 to a chamber 31, enters an aperture 42 in a disc 29, passes around a corrugated member to a chamber 33 and through openings 34, 36 to a chamber 37 from which it issues to a chamber in the mouthpiece. The Specification, as open to inspection under Sect. 91 (3) (a) also describes a modification, Fig. 9 (Cancelled), in which the bowl is fitted with a separate cup-shaped member 2 ; grooves 6 are formed on the inside of the bowl and the smoke passes from the cup member into a chamber at the bottom of the bowl, through a vertical passage to the top groove in the bowl, then through perforations into the succeeding grooves, and finally enters the chamber through a passage 7 and passes around a helical member 8 to the mouthpiece chamber. This subject-matter does not appear in the Specification as accepted.

Abstract: 432,798. Pictorial toys. HALL, M., Kenemish, Stanton - on - Hine Heath, near Shrewsbury. Jan. 27, 1934, No. 2842. [Class 132 (iii)] [See also Groups XX and XVIII] The effect of movement is produced in pictorial effects by relative movement between the picture and a background sheet having continuous or discontinuous optical lines thereon. Figs. 1 and 2 show a front sheet 7, having a picture thereon, in which apertures 8, 10, 11, are cut. A fixed sheet 6, behind the sheet 7, has a portion of the picture thereon which is visible through the aperture 8, and openings which register with the apertures 10, 11. A disc 4, rotatable on a pivot 3, carries a representation of a motor car which is visible in front of the sheet 6, while traversing the aperture 8, the lower half of each wheel being cut away, and holes 18, 19 being formed in the positions of the rear and front lamps. Apertures are also formed in the disc 4 in such positions that they register with the apertures 10, 11 for a short time during the rotation of the disc A fixed background sheet 2 has openings registering with the apertures 10, 11, the lines radiating from the pivot 3, and visible through the cutaway parts of the wheels, to represent spokes. Lamps and coloured material may be provided in connection with the apertures, and rotation of the disc produces the effect of a lighted car approaching through a hidden road, passing into an open space, and continuing along a hidden road. The disc may also serve as a crank operating other movable parts to produce further effects. Constructions are described in which vehicles, optical lines, &c., are carried by stationary screens and by one or more endless bands moving on rollers to co-operate and produce effects of movement, change of lighting in traffic signals, &c. Fig 8 shows a flat or curved stationary screen 43 carrying any desired picture provided with one or more slots 45 through which are visible optical lines 44 on a cylinder 42 secured to a fan 46 rotated by rising air from a lamp 47. Two or more cylinders rotating on the same axis at different speeds or in different directions may be used. The optical lines may be arranged and coloured in any desired manner. Reference has been directed by the Comptroller to Specifications 152,537, [Class 132 (iii)], 186,077, [Class 97 (i)], 224,637, 252,294, and 267,460, [all in Class 3 (i)].

[Class 40 (v)] The search coil or each of the field coils of a radiogoniometer is so constructed that the turns are of substantially the same size and shape, each turn having an axis of symmetry which is common to all the others. Fig. 1 shows one form of search coil in which the former is represented by two discs 1, 2, the axis of revolution being shown at 3, 4. The wire W forming the coil is wound from one end E1 in the direction of the arrows to the other end E2, two turns only being shown. The turns have an axis of symmetry QQ. In a modification, Fig. 3, the common axis of symmetry of the turns coincides with the pivotal axis 3, 4. The field coils for use with such search coils are of ordinary construction. Alternatively, the search coil may be of ordinary construction and the field coils wound as shown in Fig. 1 or 3. Harmonic errors due to variation in flux linkage of the rotor with the stator field upon rotation of the rotor are reduced by " distributing " each of the turns of the coil or coils so that the turns cross one another at several places.
