Title: Television systems
IPC: H04N7/088
Filed: 1973-02-15
Abstract: 1425637 Television BRITISH BROADCASTING CORP 8 Feb 1974 [15 Feb 1973] 7569/73 Heading H4F Blocks (i.e. pages) of digitally coded data are multiplexed on to a broadcast television signal, each different data block occupying a difference time slot, and at a receiver any one time slot can be selected for display (or storage) of the corresponding data block. In the embodiment described 32 blocks of data are multiplexed on the television signal using two lines within the vertical blanking interval of each field (e.g. lines 13 and 14 and lines 326 and 327 of odd and even fields respectively of a 625/50 television system), each block (page) having 24 rows each with 32 character places, and since the digitally coded data corresponding to only one row is transmitted during a two line period 24 (rows) Î 32 (blocks) television fields are required to transmit all the blocks of data. The data of the first block may be transmitted in the first 24 television fields or a row of data of each block may be transmitted every 24th field i.e. in an interlaced manner, as indicated in Fig. 1. Each data block cycle of 32 data blocks takes 15.36 sec., and the transmitter may be arranged to change every minute the data of any block i.e. the data in any one of the 32 time slots in a data block cycle. Thus in the transmitter described with reference to Fig 3, not shown, pages (blocks) 1-8 and 10-31 are transmitted as single pages, whereas page 9 comprises three pages 9a, 9b, 9c which follow in cyclic succession, one every minute, and page 32 comprises a fresh page of data every minute Since the 32-page (block) cycle time of 15.36 sec. does not divide into 1 minute, a page 32 data block is only transmitted in the first two complete block cycles occurring within the minute in question, there being always two such complete cycles in a minute such as cycles N + 1 and N + 2 as indicated in Fig. 2 of page 32 transmitted at 16.45 hours, two cycles of each page 32 being transmitted rather than one in each minute to improve the security of reception. Each row occupies the last half of line 13 and all of line 14, the first half of line 13 being occupied by an address including two characters defining the page number 1-32. The first row address of each page also includes a special beginning of page code to enable a receiver to correctly assemble the rows of a selected page. The changing page 32 address also includes four characters defining in 24 hour clock notation the times of transmission. In a receiver, Fig. 4, not shown, an address for a desired block is set in a register together with a time address if page 32 is to be selected and this address or addresses is compared with the received address information to gate out the appropriate information of the block (page) for storage and/or display.

Title: An improved machine for testing of materials
IPC: G01N3/14
Filed: 1935-03-12
Abstract: 450,028. Testing physical qualities of materials. WILLIAMS, G., Russell House, Stennels Avenue, Quinton, Birmingham. March 12, 1935, No. 7628. [Class 106 (ii)] A gapped ring of the material is pulled apart by a force applied across a diameter of the ring, a diagram being automatically recorded, the ordinates representing force applied and extension of the ring respectively. A plate 4 fixed to a standard 3 is provided with three spaced knife edges 5 one above the other. Within the hollow standard 3 is arranged a shaft 6 driven by bevel gear 8, 9 from a hand wheel 11 and driving at the other end gearing 14, 15 of which the latter is formed as a nut which on turning slides a screwed shaft 17 fixed to a frame 18 guided on the standard 3. Rotating in ball bearings 19 in the frame 18 is a horizontal shaft 20 to which is keyed a bracket carrying a depending arm 21 forming a swinging weight system and provided with a small adjustably clamped mass 22. The bracket carries two spaced hooks 24 each forming an anchorage for one end of a flexible steel strap 25 passing over a cylindrical or part cylindrical surface in the bracket or on the shaft 20 and coaxial therewith. The other end of each strap is anchored to a horizontal bar 26 rigidly connected by parallel rods 27 with a cross-bar 28 carrying a knife-edged projection 29 in line with the knife edge 5. The bars 26, 28 have also stretched between them piano wires 31 which are passed around and positively keyed to a cylindrical boss 32 on the shaft of a drum 35 adapted to receive a second chart. Mounted on the bracket opposite the arm 21 is a ball-bearing roller 36 engaging between the parallel edges of two light bars 37 depending from a bar 38 adapted to slide on two spaced wheels 39. One end of a rod 41 connecting the arms 37 for slight adjustment purposes, is provided with a pen 42. A scale 43 on bar 38 co-operates with a hair-line on a cursor or pointer 44 carried by a screwed rod 45. An arcuate metal strip 46 attached to the arm 21 is toothed to co-operate with a fixed pawl 47 to hold arm 21 in the position reached when the ring breaks. In use, the ring is placed over the knife edge 29 and one of the knife edges 5 and the wheel 11 turned. The pull of the frame 18 acting through the straps causes the arm 21 to swing out of the vertical. The piano wires turn the drum proportionally to the extension of the specimen and the roller 36 and arms 37 and 38 are moved horizontally proportionally to the displacement of the swinging weight or lead. The Provisional Specification describes also a modification in which the load is applied by a spring balance arrangement, the springs being stretched by a screw and nut device operated by a hand wheel. In this case, the chart-carrying drum is slidable on a vertical spindle proportionally to the extension of the springs and is rotated by wires in accordance with the movement of the movable knife-edge.
