Title: Facsimile system with data compression
IPC: H04N1/415
Filed: 1971-04-29
Abstract: 1352022 Facsimile systems MAGNAVOX CO 29 April 1971 [11 May 1970] 12210/71 Heading H4F A facsimile system transmitter comprises first means for examining a scanning area to distinguish between contrast-free areas and other areas and for providing address signals defining the boundaries between the areas, scanning means so controlled by the first means as to develop facsimile signals from said other areas only and third means arranged to transmit the address signals and the facsimile signals. The cooperating receiver comprises means for storing the received address signals, scanning means for reproducing the received facsimile signals and control means which cause the scanning means to scan the said other areas and reproduce the facsimile signals only thereon. The scanning area is considered as being divided into elemental areas, which may be black or white, with a particular number of such elements or bits to a line and each element may be assigned an address denoting its position in a line. On each line relatively long runs of consecutive white elements are detected (as described, twenty-two) to determine contrast-free areas, the boundaries of such significant runs of white being defined as addresses along the line and also forming the boundaries of data blocks in which a black element occurs at least at the beginning and end. In one transmitting arrangement, Fig. 1 (not shown) a line is first scanned at a very high rate to detect the boundaries of the first data block and to establish and store the addresses thereof and the fast scan is then stopped and the two addresses transmitted. In addition the scanner retraces and the data between the two addresses is scanned slowly and transmitted. The search for the next data block is then resumed and after detection the addresses thereof are transmitted and the data between these boundaries scanned slowly and transmitted as before, the process being repeated until all the data blocks on a line have been transmitted. The system then moves to the next line and the same procedure is repeated. At the start of each line thirty "white" bits are sent as a sync. signal. In an alternative transmitting arrangement Fig. 4 (not shown) a fast scan is used to cover a complete line and all boundary addresses for the data blocks are detected and stored. Subsequently the line is re-scanned, beginning with a jump to an address defining the start of a data block, a slow scan to the end of the data block, a fast jump to the next data block and so on. The transmitted signal for a line consists of thirty "white" bits as a sync. signal, followed by the sequence of address signals, followed by the sequence of facsimile signals developed for that line.

Title: Improvements in and relating to starting switches for electric discharge lamps
IPC: H05B41/06
Filed: 1942-09-16
Abstract: 553,481. Thermal switches; discharge apparatus. BRITISH THOMSON-HOUSTON CO., Ltd. Sept. 16, 1942, No. 13072. Convention date, Sept. 20, 1941. [Class 38 (v)] [Also in Group XL] A thermal switch for starting discharge lamps comprises two thermally-operated contact arm; 10 11<SP>1</SP>, moving in the same direc. tion, one, 10, caused to be more sensitive in action either by being made of thinner material or being raised to a higher temperature than the other, an electric circuit shunting the contacts and generating heat either by " glow " or resistance to close the contacts. And a stop 16<SP>1</SP> for limiting the movement of the more sensitive arm 10. The quicker movement of the arm 10 may be obtained alternatively by siting a heater 17 nearer to 10 than to 11<SP>1</SP>, or by shielding arm 11, as by means of the stop member 16<SP>1</SP> or by providing a thermal mass 21 in contact with 11<SP>1</SP>, or, in a modification, Fig. 3 (not shown), by winding both bimetallic strips with resistance heaters one of greater capacity than the others. On switching on, both arms 10, 11', bend to the right as shown, arm 10 faster than arm 11 to close the contacts. On repeated efforts at starting the lamp, arm 11 is bent beyond the range of arm 10 limited by the stop; and the switch is locked open. Where a "glow" " heating is used, the case 20 is of glass and filled with suitable gas.

Title: Improvements in coin selector mechanism
Inventor: DOLMAN HENRY JAMES
Filed: 1955-05-06
Abstract: 775,231. Testing coins. BRECKNELL, DOLMAN & ROGERS, Ltd. Nov. 28, 1955 [May 6, 1955], No. 13131/55. Class 27. Coin testing mechanism comprises adjustable means for testing the diameter, thickness and weight of coins, a magnet 22 for arresting ferrous coins, adjustable means for checking the presence of a rim on a coin and rejecting a rimless coin and a rebound plate 50 and stop 52 for rejecting " soft coins. A hinged clearing wall 5 having an inclined coin track 16 is spring-biased towards a support 1 and its spacing from the wall can be adjusted for two thicknesses of coin by screws 11 and by changing over washers on fixing bolts for hinge lugs 7 from one side of the support to the other. A too-thick coin cannot enter the coin track and a too-thin coin is rejected through the slot between the track and the support. A ledge 19 above the track is adjustable vertically to gauge the coin diameter by means of screws 21 and slotted holes, coins of too-small diameter toppling sideways through an aperture 4 in the support to a return shoot. A coin that passes the diameter and thickness tests and is not arrested by the magnet 22 drops into a pivoted bucket 28 counterbalanced by a set weight 30 and one or more adjustable weights 31. The bucket has a fixed claw 40 adjustable on a screw 41 by spacing washers and a spring-loaded pivoted claw 39 adjustable by reversing a stepped bracket 37A on which it is mounted. If a rimless coin enters between the claws, they fail to hold it as the bucket begins to swing down and it falls to the return shoot, and a coin of excessive thickness inside its rim forces the claw 39 outwards so that it engages a stop screw 43 and prevents downward swinging of the bucket. A too-tight coin fails to swing the bucket down and is retained until another coin enters, when both coins are rejected because, when combined, they are over-thick. A coin still held by the claws as the bucket swings down is removed by a stripper foot 47 angularly adjustable by a screw 49 and slot 48 and falls to the rebound plate 50. The diameter of coin accepted by a coin slot in the support is adjustable by a slotted coin rest 14 secured by a screw 15. Automatic clearing. When the clearing wall 5 is moved away from the support 1 by linkage between the coin-controlled mechanism and a leg 8 of the wall, any coin held at the entry to the coin track 16 is released, any coin held by the magnet is dislodged by a stripper 19 secured to the support and any coin held in the bucket is removed by a spring-loaded stripper 44 pivotally supported on the wall hinge pin 6.
Patent GB-132608-A (GB)
IPC: B63C7/04
Abstract: 132,608. MacGregor, J. Sept. 18, 1918. Sunken ships, raising.-A hawser secured to, or passed under, the sunken vessel is passed round a winding-drum C arranged co-axially with, and between, two cylindrical chambers A, the other end of the hawser being passed round a similar drum arranged between similar chambers. The chambers A are divided into radial compartments, the necessary pipes N and valves 0 being arranged so that the chambers and winding-drums are rotated by pumping or expelling water from one compartment and pumping water into the compartment diametrically opposite. Running centrally through the chambers and winding-drum is a tunnel E in which are arranged the electricallyoperated pumps M and the valve connexions. An operating-platform 2, shown at right-angles to its normal position, is mounted on rollers which run on rails round the wall of the tunnel, so that the platform normally maintains an horizontal position during the rotation of the pontoon. Access to the tunnel is obtained through an air shaft K, J journaled in the end of the tunnel and maintained in a vertical position by a weight K<2>. Electric power may be supplied to the motor L through the shaft K, J, one or more sliding contacts being provided between the non-rotary shaft and the rotary body of the pontoon. Instead of electrically-driven centrifugal pumps, compressed air may be used for displacing the water in the ascending compartments of the pontoon and a submersible pump arranged to fill water into the compartment diametrically opposite. When the sunken ship has been raised as far as possible by the rotation of the requisite number of pairs of pontoons, extra hawsers are passed under the ship and are secured to each pair of pontoons in an opposite direction to the winding of the first hawsers. Valves provided for the purpose are then operated, and all the ballast water is pumped out of the pontoons. Instead of being manually operated, the various valves may be actuated automatically by electro-magnetic or compressed-air gear controlled by a rotary switch or valve fixed to, and rotating with, the pontoon and having a pivotally-mounted bridge-piece which is prevented from rotation by a pendulum weight.
