Abstract: 1,120,851. Gap scatter removal. AMPEX CORP. 21 Sept., 1966 [7 Oct., 1965], No. 42177/66. Heading G5R. The effects of gap scatter, i.e. the deviations of the position of binary data signals transcribed on a magnetic tape by a multi-channel recording head from a line transverse to the tape, are eliminated by varying the amplitude of the signals applied to the individual heads whereby the position of the maximum flux gradient of the leading and lagging edges of the individual transcribed signals are varied in the direction of the length of the tape. In the arrangement described tape transport 20 halts the tape 11 whilst signals are recorded by the heads 10. The heads are fed from a data source 15 via amplifiers 16 and adjustable resistors 17. Assuming the maximum flux gradient of the leading edges of the transcribed signals are brought into alignment across the tape width the signals associated with these edges are selected in the playback circuits 12, 26-28.

Abstract: 1,118,344. Editing television tapes. FERN. SEH G.m.b.H. 6 Oct., 1965 [6 Oct., 1964], No. 42498/65. Heading G5R. In a system for editing a combined video and audio tape, takes 1, 2 and 3 on tapes MI and MII are transferred to a single tape MIII. The beginning and end of each take is determined by splicing marks U preceded by start marks S, which occur 20 seconds earlier. Take 1 is rerecorded on tape MIII, and when its start mark S reaches the magnetic head, tape MII is started and after 20 seconds the U mark causes changeover to tape MII. Tape MI now stops and tape MIII rerecords take 2 from tape MII. Tape MI is advanced under manual control so that when the next S mark is reached, tape MI is started with the result that when the associated U mark reaches the magnetic head, take 3 on MI is rerecorded on tape MIII. An arrangement of controls to effect this operation is described, Figs. 3 and 4 (not shown).

Title: Improvements in and relating to tubular film of plastics material
Inventor: DICKSON ROBERT WALKER
IPC: B29C53/10
Filed: 1964-10-20
Abstract: 1,114,930. Plastics bags. BRITISH VISQUEEN Ltd. 6 Oct., 1965 [20 Oct., 1964], No. 42735/64. Heading B8K. [Also in Division B5] Apparatus for producing film of plastics material in flattened tubular form, having a longitudinal area or areas of its outer surface treated to improve its bonding property towards printing inks, and including means for continuously advancing the tubing in flattened form, and means for subjecting at least one surface of the advancing tubing over a controlled width to high voltage electric stress, is characterized in that it includes means for imparting a controlled twist to the tubing after treating. As shown, said means for imparting a controlled twist to the tubing, may comprise, in the path of the tubing, two pairs of nip rolls 5 and 6 spaced apart from one another, each pair being adapted to seal off a gaseous medium held within the tubing in the section thereof extending from the first pair of nip rolls 5 to the second pair 6 and at least the second pair being driven to withdraw the tubing and the second pair of nip rolls being adapted to be set at a predetermined angle relative to the first pair about the longitudinal axis of the path of travel of the tubing and to be held in such position, for the purpose of imparting said controlled twist to the tubing. Means for printing one or both surfaces of the flattened tubing (not shown), after it has been subjected to high voltage electric stress, (3) but before any twist is imparted to it, may be supplied. Means in advance of the second pair of nip rolls for forming a gusset at each side of the advancing tubing may also be provided (10, Fig. 2). Thus, in Fig. 1, tubing 1 passes around rolls 2 and 3 and each side is subjected to high voltage electric stress from apparatus 3. The tubing then passes around rolls 4, is inflated between rolls 4 and 6, and is twisted while passing between rolls 5 and 6 which are at an angle to one another. In Fig. 1, the inflated tubing passes through guiding bars 7 and V-guide 8 to nip rolls 6. In Fig. 2 the inflated tubing is twisted between nip rolls 5 and 6 and contacts gussetting blade 10 and is collapsed by means of guide rolls 9. A tubular film is preferably made of polythene, and preferably exceeds 0À005 inch in thickness. In operation, the original side folds of the film which are not treated by high voltage electric stress, are displaced, so that the new folds formed lie along an area of the film which has been electrically treated and thus may be readily printed. Such film is useful in making sacks, the printing of the edge fold area being clearly visible in a pile of such sacks. Sacks are readily made by forming transverse heat seals at sack length intervals across the length of tubular film treated by the method described, and severing the sacks from the lengths of tubing at one side of each seal.

Abstract: 1,003,129. Variable-speed epicyclic gear. INPOWER WORKS (PROPRIETARY) Ltd. Nov. 29, 1961 [Dec. 24, 1960; March 10, 1961], No. 42772/61. Heading F2D. An epicyclic variable speed gear varying automatically up to solid 1/1 ratio comprises planets 28 on a driving (or idling) carrier 6 meshing an output sun 10 through a chain drive or, as shown, idler planets 20, bucket wheels 30 fast on the planets 28 and having generally circumferentially directed buckets 32, and an idling (or driving' rotatable drum 18 toothed or, as shown, friction geared to the bucket wheels or toothed geared direct to the planets 28 (Fig. 5, not shown), the buckets 32, reversely driven about the axis of the planets 28 due to output resistance, scooping liquid, by their outer lips, from a centrifuged annulus 104 in the drum 18 and discharging it near the drum axis for return to the annulus 104 past the planets 28 axis, and the liquid held in the inwardly directed buckets centrifugally resisting reverse rotation and imparting a forward driving torque on the output sun. Variations of the output torque characteristics is effected by suitable direction of the bucket openings relative to the bucket wheel/planet 28 axis. In addition, to provide a h igh starting torque, a drag torque is imposed on the bucket wheels by the passing of the buckets through the liquid annulus 104 when input speed exceeds output speed. The relative speed (before solid drive) between the buckets and the annulus 104, and hence the drag torque, may be predetermined by suitably choosing the diameter of the drum and bucket wheel/planet 28 engaging diameter. As shown, the bucket wheels planets 28 are bushed at 24 and rotate on pins 4 fast on swing arms 22 which pivot about idler planet axis pins 8 fast on the carrier 6. The swing arms may be outwardly spring biased (Fig. 4, not shown). In Fig. 5 (not shown) the pins 4 are pivoted on pins fast on, and tangentially directed with respect to, the carrier 6. Reference has been directed by the Comptroller to Specification 949,175.

Abstract: 1532637 Optical projectors S BESANCENOT 21 Oct 1975 [21 Oct 1974] 43119/75 Heading G2J [Also in Division F2]  Slide-changing mechanism for a projector, of the kind in which the mechanism is operated by a push-rod (1), Fig. 3, (not shown) pivoted to the end of a crank arm fixed to a shaft 2 which is continuously driven by an electric motor (not shown) through two stages of gearing, includes an arm 11 which disengages the two stages in turn. In operation, a gear-wheel 10 fast on shaft 2 engages a pinion 9 fast with a gear-wheel 7, both of which are freely mounted on a shaft 8 fixed to an arm 11 pivoted at 12. Gear-wheel 7 engages a pinion 6 continuously driven by the motor. One end 14 of lever 11 is spring-urged against the armature 15 of an electromagnet. When the electromagnet is not energized, the armature 15 takes up the position shown in faint lines, and lever 11 rocks about its pivot to disengage gear wheel 7 from pinion 6, and pinion 9 from gear-wheel 10. When a slide change is to be made, the operator presses a button which energizes the electromagnet for a short time. The armature 15 moves to its full-line position, pivoting lever 11 so that first gear-wheel 7 engages pinion 6, then pinion 9 engages gear-wheel 10, and the motor drives shaft 2 through the gears. At the same time a stud 13 at the other end of lever 11 enters a gap 19 formed in a flange 18 of the gear-wheel 10, pushing back a shoe 20 against action of a spring 21. When the electromagnet is de-energized, the gear-wheel 10 has turned so that stud 13 is trapped by flange 18, until the gear-wheel has completed one revolution, during which the push-rod (1) makes a complete excursion. At the end of the revolution, spring- loaded shoe 20 ejects stud 13 from the flange 18, and the gears are disengaged once more.
