Abstract: 1,253,303. Storage drums. SCAPA-PORRIT Ltd. 24 Feb., 1970 [15 March, 1969], No. 13715/69. Heading B8M. A storage drum comprises a flanged reel 11 arid a body part 12 on which the reel is rotatably mounted, the body part 12 including side walls in closely adjacent disposition to the flanges at the periphery thereof and continuing about the periphery and a series of bridge pieces 12c angularly spaced about the periphery of the reel and extending closely adjacent said periphery. The body part 12 comprises two discs 12a, 12b closely adjacent the flanges 11a, 11b of the reel. Each bridge piece 12c has a pair of slits 12c<SP>1</SP> parallel to the lateral edges of the .bridge piece, the slits engaging the peripheries of the discs 12a, 12b at the required axial spacing. In operation, a wire 13 is secured to and wound on a central sheath or hub 11c, rotation being effected by means of a handle 14b attached to a disc 14a which mates with the shaft of the reel through an aperture 12a<SP>1</SP> in the disc 12a of the body part. When winding-on is complete, the bridge pieces 12c are placed in position to prevent radial movement of the turns of wire. Two bridge pieces 12c are placed closely adjacent each other, these two pieces having a central aperture to receive the end of the wire and thus prevent unwinding. To unwind the wire, the end of the wire is first removed from the said two bridge pieces. In an alternative embdoiment, the flanges of the reel are formed from radial arms.

Title: Improvements in or relating to electrical control circuits, particularly for television and the like
IPC: H04N5/272
Filed: 1935-05-11
Abstract: 456,582. Television. CHAPTER, C. F., and BAIRD TELEVISION, Ltd., 58, Victoria Street, Westminster. May 11, 1935, No. 13860. [Classes 40 (iii) and 40 (v)] A method of producing "rolling cuts" from one of a plurality of scenes being simultaneously scanned at a television or like transmitter to another, comprises controlling a plurality of amplifiers to which the outputs from an equal plurality of simultaneously operative scanning devices are respectively applied so that only one of the amplifiers is operative at any one time. Various ways of producing " rolling cuts" are referred to and each amplifier may be rendered operative during the scanning of at least a portion of any one frame or of at least a portion of each scanning line. Fig. 1 shows a system employing two scanning devices S1, S2 associated respectively with control amplifiers CA1, CA2, the outputs from which are applied to a mixer M. Synchronizing signals from a generator SG and image signals from the mixer M are applied to a transmitter (not shown). The generator SG also controls the scanners S1, S2 and the control circuit CC. When changing over from one scene to another, the scanners are rendered operative and inoperative alternately as required by increasing the bias on one of the amplifiers by the control circuit and at the same time decreasing the bias on the other amplifier and vice versa. Fig. 2, shows the control circuit by which the alternation of cut-off bias between S1 and S2 is effected. M1, M2 are magnetron valves each of which is situated in a magnetic field, provided by bias coils B1, B2, of a strength just greater than the critical value. In the anode circuits of the valves are arranged " holding " coils H1, H2 and resistances R1, R2 across which are developed the cut-off bias potentials for the amplifiers CA1, CA2 respectively. A " trip " coil T1, T2 is also associated with each valve as shown, these coils being so connected in series that a current passed through both coils increases the magnetic field of one valve and reduces that of the other. Thus by passing current impulses of appropriate value and direction through the coils T1, T2, the bias potentials on the amplifiers CA1 and CA2 can be suitably controlled. For the type of cut in which the line of cut is vertical and moves across the screen, the pulse generator may be locked to the line synchronizing circuit through a control network of the type described in Specification 451,786, [Group XXXV], and the cut effected by slowly rotating the potentiometer of the control circuit. For the type of cut in which a horizontal line moves up or down the screen, the pulse generator may be similarly controlled from the picture synchronizing circuit.
