Title: Elongate information-bearing strip and to modifying elongate information-bearing strip
IPC: G03B31/02
Filed: 1976-04-28
Abstract: 1522089 Editing sound films B W ANDERSON 28 April 1976 [30 April 1975 (2) 15 Dec 1975]  17363/76 Heading G2E [Also in Divisions G4-G6] In an elongated strip having three longitudinally extending bands, each of which can carry sequentially recorded information (e.g. one being a sequence of film images and the other two capable of acting as sound tracks), sound actually recorded on one track is read and recorded on the other sound track at a position longitudinally offset from the first. The invention is used in editing a sound film strip, such as is shown in Fig. 4. This carries a sequence of film scenes on successive frames  18Aa, 18Ab,&c. The corresponding sound is recorded on a magnetic sound stripe 24 (called the principal stripe), the sound being customarily eighteen frames in advance of the film frame to which it relates. Thus as shown in Fig. 4, the crosshatched portion of stripe 24 adjacent frame 18Ab corresponds to the frame 18At. Such an arrangement presents difficulties when editing is required, since corresponding frames and sound are not adjacent but longitudinally offset, so that if a selection of film is cut out and removed, the section of sound track also removed does not correspond. The film strip shown has an additional magnetic stripe 28 along the opposite edge to stripe 24, which acts as a balance stripe. It is known, however, to also make use of the balance stripe for additional sound recording. In the present procedure, two reading and recording sound heads 48, 50 are provided, spaced eighteen frames apart, and located over stripes 24 and 28 respectively. These heads are connected to switching and amplifying devices 56, 58. For an editing operation the tape is moved in direction A. The sound recorded on stripe 24 is read by head 48, and recorded on stripe 28 by head 50, so the sound on stripe 28 now corresponds with the adjacent film frames. The film can now be edited, since the removal of a section of the film will involve only the removal of the corresponding sound track on stripe 28. The film is once again moved in direction A, but this time switch 56 is changed over so that head 50 is the reading head and head 48 the recording head, which at the same time erases any sound information still remaining on stripe 24. Thus the sound on stripe 28 is transferred back on to stripe 24 at the proper longitudinally offset position. Fig. 6 (not shown), is a practical realization of an apparatus for editing the film, incorporating a viewing screen, so that the film may be viewed during the editing process. In Fig. 9 (not shown), the editing system of the invention is incorporated into a film projector. The balance may also be utilized for an additional sound track, or for the superimposition of background music.

Abstract: 759,968. Aerials. BELLING & LEE, Ltd. May 20, 1955 [June 16 1954], No. 17696/54. Class 40 (7). A wireless aerial arrangement intended for operation at two frequencies which are not odd-harmonically related consists of a half-wave dipole comprising elements 10 and 11 designed for operation at the lower frequency and coupled to a feeder at the central supporting insulator 12. A shielding mem ber consisting of rods 14 and 15 is arranged to extend along the dipole elements for equal distances on either side of the insulator 12 and to be of such length that the remaining portions of the elements extending beyond the shielding are an odd number of quarter-wavelengths long at the higher frequency. The arrangement is suitable for use as a receiving aerial for television signals in one channel of band I and in band III. The shielding member need not be in the form shown but may be continuous, reticulated, foraminated, or in the form of a cage. It may be supported by resilient clips of insulating material, such as polyethylene, which can be sprung into position on the dipole elements (Fig. 2, not shown). The shielding member may, if desired, be electrically connected to the support arm 13. The arrangement may be associated with unshielded parasitic elements resonant at either or both operating frequencies. A screen member of suitable length can also be used in conjunction with a single quarter-wave element (at the lower frequency) and extend from the feeder end a length such that an odd number of quarter-wavelengths at the higher frequency is left unscreened. The invention contemplates the provision of " add-on " screen devices to enable existing dipoles or quarter-wave elements to be used also at a higher frequency.

Abstract: 613,971. Grinding. FELLOWS GEAR SHAPER CO. June 13, 1946, No. 17797. Convention date, July 21, 1945. [Class 60] [Also in Group XXII] A machine having a rotary-cutter for cutting teeth or grooves in a work-piece comprises means for reciprocating the work-holder and cutter-holder relatively to one another on a path transverse to the cutter axis, the means for effecting reciprocation and rotating the cutter being correlated to vary the angular velocity of the cutter so that the linear cutting-speed is substantially the same in each direction of traverse. In a gear-cutting machine, the cutter C is mounted on a carriage 16 which is reciprocated on guides 15, 17 across the face of a gear-blank W. Cutting takes place on each stroke, the cutter being advanced into the work or the work indexed at each reversal. The cutter is rotated by a worm 41, mounted on the carriage-base 13, meshing with a wormwheel 43, having a diameter approximating to that of the cutter, mounted on the cutter spindle 20. As the carriage reciprocates, the rolling of the worm-wheel on the worm cancels out the effect on the angular motion of the cutter of its linear displacement. The carriage 16 is reciprocated by hydraulically-actuated pistons acting on each side thereof. The base 13 is vertically adjustable and is steadied by massive guides 153. Alternatively, the workholder only or the work-holder, the cutter holder and the worm may be reciprocated. The worm may be arranged below or at the side of the cutter. The cutter may be a grinding- wheel.
