Title: Bottle handling apparatus
IPC: B08B9/44
Filed: 1975-08-04
Abstract: 1484097 Bottle conveyers SHIBUYA KOGYO CO Ltd 4 Aug 1975 [5 Aug 1974] 32562/75 Heading B8A Alternate rows of pockets 4 of a bottle handling conveyer 2, e.g. in a bottle washing apparatus, are fed with bottles from a feed conveyer or conveyers at spaced locations along the conveyer 2. As shown, the spaced locations are fed by respective feed conveyers 9a, 9b. Each end of a rotary pusher bar 19a is carried by a respective rotary member 18a (one only, visible in Fig. 2). The members 18a are given a cyclic movement (to periodically displace the bar 19a) by being connected to planetary gearing 15a, 16a driven by a shaft 14a. A similar mechanism 14b-19b is associated with the conveyer 9b. The push bar 19a pushes a row of bottles from the conveyer 9a on to the tips of fingers 21a. Each finger 21a lifts respective bottle up parallel guides 20a. Fingers 29a interdigitating with the fingers 21a, push the bottles into a row of pockets 4. The fingers 29a are operated by a kidney shaped cam 23a, acting on a segment 26a, and gears 28a, 27a. Similar mechanism 21b-29b operates between the pusher 19b, and the alternate pockets 4, not filled by the conveyer 9a and associated apparatus. Discharge of containers from the pockets 4 to discharge conveyers.-A row of bottles is received from the pockets 4 to bottle supports 33a carried by arms 34a when the latter are in their support positions adjacent a gap 54 in a guide 31. While the supports 33a are in this position, a pair of rollers 40a at each end of a pusher bar 41a are drawn to a retracted position resting on extensions of receiving boards 43a. After the supports 33a have carried a row of bottles from the pockets of the conveyer 2, to the receiving boards 43a, the row is pushed by the bar 41 on to the discharge conveyer 12a. The pusher bar 41 and the supports 33 are actuated by the same mechanism (crank 44a, push rod 47a, cam follower 50a, and cam track 52a), but a lost motion mechanism delays the movement of the bar 41 so that it does not operate prematurely. A cam track 65, cam follower 62, and link 60, cause reciprocation of a member 53 which blocks the release of alternate rows of containers to the supports 33. The mechanism is duplicated for discharge of the alternate rows to a second discharge conveyer 12b.

[Also in Division H2] Longitudinal and/or torsional vibrations of sonic or ultrasonic frequency are induced in a bar 6 (Fig. 1) or 16 (Fig. 3) by the alternate attractive and repulsive forces and by the torque between a disc 5 (Fig. 1), or 11 (Fig. 3), comprising a plurality of segments magnetized axially and with adjacent segments of opposite polarity (see Figs 2 and 2a) or magnetized tangentially (see Figs. 4 and 5) secured to the bars which are supported at vibrational nodes 7 or 16 and a similar disc 2 (Fig. 1) or 11<SP>1</SP> (Fig. 3) secured to shafts 4 or 18 which are driven at a speed such that the frequency of alternation of the attractive and repulsive forces between the discs is equal to the frequency of the natural longitudinal vibration of the system formed by the bar 6 or 16 together with the disc 5 or 11 respectively. To increase the magnitude of the vibrations the driving shaft and the vibrated shaft may each be provided with a pair of magnetic discs 11<SP>1</SP>, 11a<SP>1</SP> and 11, 11a respectively, (Fig. 6). In the arrangement shown in Fig. 2 and 2a, the discs may be constructed from individual segments of sintered magnetized material separated by spacers 8a, 8b etc. of diamagnetic material or, a single piece of such material magnetized in the required manner may be employed. In the arrangement shown in Figs. 4 and 5, the discs are constructed from segments of ceramic material 12 magnetized tangentially and inserted in incisions in a " plate " formed by winding a plurality of layers, e.g. 13a, 13b, 13c etc. of a material of high magnetic saturation. The assemblies are secured by adhesion to discs 14, 14<SP>1</SP> of non- magnetic material and enclosed by a band of similar material. For ease of starting the two discs are separated by a considerable distance which is reduced when the desired rotational speed has been reached preferably under the control of automatic means such as a centrifugal governor or by electronic means. To avoid overheating due to eddy current losses air-cooling of the assemblies may be effected by providing blades in the axial space between the discs or the latter may be provided with obliquely directed bores or slots. Applications of the invention referred to are: the production of vibrations in liquids; the atomization of liquids; drilling; welding (steel and plastics); emulsifying and dispersing, the end of the bars 6 or 15 being suitably shaped themselves or provided with suitable tool attachments. For the atomization of liquids the latter is supplied via a hole situated at the vibration node (7 or 16) of the rod and emerges via an axial bore ending in fine outlet bores in the end face of the rod which in this case is tapered or stepped down to a smaller diameter to provide a " speedtransformer " effect.

Title: Improvements in or relating to warp-knit fabrics
IPC: D04B21/00
Filed: 1965-08-03
Abstract: A warp knitted fabric is given a bulky appearance by knitting a grooved fabric from at least one set of yarns and simultaneously incorporating a second set of yarns on a single or double needle chain stitch effect such that the amount of yarn of the second set expressed in units of length is at least 1.4 times that of the first set of yarns.  The first set of yarns may be knitted in tricot stitch or satin stitch and more than one set of ground yarns may be knitted. Smooth filamentary yarns may be used for both the ground fabric and for the yarns producing the bulky effect.  The yarns may be polyamides, polyesters, polyolefines, polyethers or other thread forming polymers.  The difference in the amount of yarn supplied by the guides supplying the yarns for producing the bulky appearance is achieved by increasing the rate of delivery of the corresponding warp beam or supply or other yarn feeding means.
