Title: Electrical rotary machine
IPC: H01R39/39
Filed: 1969-11-07
Abstract: 1,261,955. Brush holders for dynamo-electric machines. INTERNATIONAL BUSINESS MACHINES CORP. 7 Nov., 1969 [18 Nov., 1968], No. 54612/69. Heading H2A. The current collecting brush 36 in a rotary electrical machine is pivotally coupled to a leaf spring 44 which biases the brush towards the cylindrical current-collecting surface 26. In Fig. 4 the silver graphite brush 36 is coupled to leaf spring 44 by a ball-and-socket joint comprising a steel ball-bearing 40 glued into a cavity 42 in the brush and a concave depression 46 in the spring 44. Disengagement of the ball from the socket is prevented by a member 48 which has a portion 50 formed with flanges 52 (Fig. 3, not shown) crimped to the brush and a portion 56 which restricts relative movement of the brush and the leaf spring by engaging the depression 46. Further projections 60, 64 of the member 48 limit the relative movement in other directions. In another embodiment (Fig. 5, not shown) a hemispherical projection on the leaf spring constitutes the "ball" and engages a corresponding depression in the brush. The ball- and-socket joint is disposed at the centre of the brush if the electrical machine rotor is adapted for bidirectional rotation, and nearer the trailing edge of the brush if the rotor rotates in one direction only. The leaf spring 44 is secured at its fixed end in a moulded phenolic body (68). Current is conducted to the brush via the leaf spring and a flexible braided conductor (66) interconnecting the leaf spring and member 48. The brush is shown in use in a motor, Fig. 1, having a low-inertia rotor 16 comprising a thinwalled tube of epoxy filled glass fibre with printed conductors on both its inner and outer surfaces, a portion 26 of these conductors constituting the commutator. The stator comprises permanent magnets 18, with poles 20, supported by a collar 22 mounted on frame 12. The rotor includes an extension 16a supporting a capstan 34 which drives a flexible web, e.g. a magnetic tape or a belt, the whole rotating assembly being mounted on bearings on a fixed shaft 28.

IPC: A01K9/00
Filed: 1968-11-19
Abstract: 1,214,400. Drinking appliances. G. K. CROOKS. 19 Nov., 1968, No. 54736/68. Heading A1M. [Also in Division F2] Animal liquid feeding valve, preferably for laboratory animals, comprises a valve member 1 including a closure part positioned on the upstream side of a seat 3 and a stem 2 which extends through the seat and through a protective cylinder 8 on the downstream side. The valve member is biased to a closed position by a spring 4 on the inlet side, and is adapted to be tilted by the animal to open the valve. The amount of tilting, and hence of the opening, is controlled to suit the size of animal to be fed, by an axially adjustable screwed ring 7 in the cylinder 8. This arrangement avoids the need to reduce the supply pressure for smaller animals, and reduces the risk of bacteria gaining access to the supply. Also, animals such as rats cannot gain access to the spring. The device can be secured to a clip on the wall of a cage by a nut 16, or to wire netting by a spring-finger washer (18), Fig. 1 (not shown). A filter 11 is included.

The particular description relates to two fasteners each having hooks or loops but not apparently, both hooks and loops. In Figure 1 a base sheet 11 is passed under a sewing machine 13 which stitches loops 14 (Figure 3) over rods 16 and forms understitches 15 on the base of the material 11, the stitched sheet is then heat treated to set the loops and a adhesive coating 17 (Figure 5) is applied to the rear of the sheet to secure the under stitches thereto. The loops are then severed by a cutter 18 to form hooks and the rods 16 are then moved laterally to free them from the stitches. The cutter 18 may either sever the loops 14 or cut a portion therefrom. In place of the rods 16 the loops may be supported during severing by temporarily placing against the loops a rotary or other member, the rods 16 may be replaced wires of water-soluble polyvinyl alcohol which is dissolved after severing, or the rods may be replaced by a sheet of lead with upstanding ridges over which the loops are stitched; the sheet being pulled from the fastener after severing. The thread forming the hooks may be nylon monofilament. The loops may be formed of finer gauge thread than the hooks and are not severed. They may be of multifilament thread and the loops may be randomly oriented and thereafter brushed to separate the individual filaments to produce a multiplicity of loops.
