Abstract: 1322577 Film splicing EASTMAN KODAK CO 2 Oct 1970 [2 Oct 1969] 46900/70 Heading G2C Photographic films are conditioned prior to splicing by briefly exposing the non-emulsion side of the film to radiation which vaporizes any oil and fuses the remjet coating (if present) to the film base, without burning the film. Preferably a high intensity flash exposure is used. The conditioning may be effected in an apparatus having an apertured film support having guides arranged to align two film ends over the aperture and a flash lamp arranged under the aperture for conditioning the film ends for splicing.

[Also in Division H2] In an electrical machine having an electronic commutator arrangement the conduction of semiconductor devices connected to an n phase star winding 1, 2, 3 are controlled by a bridge circuit having branches formed by a resistor RO and a magneto-resistive element A, B, C so that in one revolution of the rotor, the winding will pass n overlapping pulses of current causing the resultant flux vector to transverse 360 degrees in 2n steps. In the D. C. motor shown having a permanent magnet rotor 4 the magneto-resistive elements A, B, C are secured to the stator by an adhesive so as to control the conduction of transistors I, II and III and cause the rotor to step successively through angles of 120 degrees. Part of one end of the rotor is removed Fig. 2 (not shown) so as to ensure that the magneto-resistive elements responds only to one pole of the rotor field. The other end is similarly shaped or drilled with holes to balance centrifugal forces. The power supply is provided from two sources U, U v  or alternatively, a single source, a rectified transformer output, or a rectified transformer output driven by an inverter may be used Figs. 6, 7 and 8 (not shown)., Speed control. The speed of the motor may be varied by adjusting the supplies provided that the ratio U: Uv is maintained constant. A circuit for maintaining the speed constant is described Fig. 9 (not shown), in which the voltage induced in one of the stator field windings 2 is passed via a transformer (17) and rectifier (19) to a bridge circuit (16) for comparison with a Zener diode (Z) voltage.

A cable guide roller has a body part 19 affording a peripheral running face 11 and a fixed first radial flange 10, and also has a second radial flange 12 which is axially displaceable relative to the body part towards the first flange to the position shown by the dotted lines. The flange 12 is screw-mounted on pins 27, slidably mounted in bores 30 in the body part, and is retained in the normal extended position by springs 13. A locking device prevents inward movement of the flange 12 until a locking pin 16 is pushed in thereby downwardly retracting a locking piece 14, which normally abuts the inner faces of the body part and the flange 12, to the position indicated in Fig. 4 (not shown). In a mono-rail cableway, Figs. 1, 2 (not shown), an actuating bar 18 on a carriage contacts the locking-pin 16 and pushes the flange 12 inwardly, thereby allowing passage between two adjacent rollers of coupling means connecting the cable and the carriage.

Title: Forming shrink covers to articles
IPC: B65D75/00

Abstract: 1,065,098. Heat-shrinking wrappers. W. R. GRACE & CO. Dec. 13, 1963 [Jan. 29, 1963], No. 49419/63. Heading B8C. A sheet of heat-shrinkable thermoplastic film is trapped by its edges between a hot-plate and a bed-plate to restrain it while it is shrunk, and is then allowed to snap elastically on to the article it covers. In the machine illustrated a platform 30 (Fig. 1) raises the article to be covered through a hole 26 in a resiliently-surfaced base-plate 24 so that it raises part of a sheet 33 of thermoplastic film. A hot-plate 16, with a hole 22 to receive the article, is then lowered so that the film is gripped between the hot-plate 16 and the bed-plate 24 as it is heated and cut by a guillotine 23. When the hot-plate 16 is subsequently raised the heated portion of the film snaps around the article where it may be retained by a bead on the top edge of the article, or by engagement under the article as indicated in Fig. 3. A second wrapper may then be applied to the article of Fig. 3, so that an opening 41 is on the opposite side from that in the first wrapper. The article may be coated with wax to provide a heat seal with the cover. In alternative forms of the machine the hot-plate 16 may be stationary, and the bed-plate 24 move, and the hot-plate may serve to lift the article into the region of the bed-plate. The hot-plate may be formed as a perforated roller bearing in turn on successive bed-plates carried on a conveyer. Wrinkles in the wrapper may be removed by'subsequent local heating by hot air. Where a square wrapper is applied in this way around a circular article four corner tabs, which facilitate tearing the wrapper away, are left. Tearing may also be facilitated by a bead 42 (Fig. 3) formed by the heated guillotine 23 (Fig. 1).

The said device comprises the provision of a pair of helical pinions 68, 70 of opposite hand fixed to the opposite ends of a common shaft 66 that is mounted to allow axial float so that high torque loading at one pinion 68 or 70 causes axial movement of the shaft and therefore also an incremental rotation of the output at the other pinion 70 or 68. The helical pinions 68, 70 drive further gear 72, 74 which drive the rack pinions 84, 184. Alternatively the rack pinions may be the helical pinions and be connected by a bridge mounted to float transversely of the guideways 160.

Either of two keys (17, Fig. 1, not shown) corresponding respectively to insertion and ejection of a sheet, when depressed cause a motor (2) to be coupled to a shaft 30. The insertion key displaces a rod 60 to the right in Fig. 3 to couple an axially slidable gear 33 with another axially slidable gear 32, the two being shifted rightwardly by an arm 52 until the gear 33 is coupled to a gear 31 whereby the shaft 30 is coupled to the platen 5. The platen is thus rotated until a projection 44 on the gear 33, preset by turning a setting wheel 34, engages an arm 53 whereby the connections are broken and platen rotation ceased. At the same time, a paper bail (10, Fig. 5, not shown) is lifted from the platen to allow the sheet to pass freely round the platen. The ejection key displaces a rod 59 to the left, whereby the gear 32 is shifted leftwards to couple the shaft 30 to the platen for as long as the key is held depressed, in order to eject the sheet.
