Patent GB-1395067-A (GB)
Title: Tunnel furnace
IPC: F27B9/24
Filed: 1972-07-04
Abstract: 1395067 Tunnel furnaces DEUTSCHE GOLD - UND SILBER - SCHEIDEANSTALT 4 July 1972 [7 July 1971] 31157/72 Heading F4B A tunnel furnace for continuous firing or sintering of elongated ceramic mouldings comprises a housing 1, a lining 2 and a well structure formed within the furnace by hollow refractory block elements 4 dividing the interior into a firing zone 8 and a flame zone 3. The blocks 4 have openings 6 towards which the flames from burners 5 are directed, the gases filling the zone 3 and penetrating into the blocks 4 and heating the walls 7 which radiate heat into the zone 8. The walls 7 are thinner than the other walls of the blocks 4. Hot gas diffusing through the wall structure is removed by suction through tubes 10. The material 15 to be treated is mounted in an arched cover 13 having insulation 14. The cover 13 has rollers travelling on rails and thus forms a trolley that moves along the top of the furnace carrying the material slowly through the furnace. The trolley is cooled by drawing in outside air through a gap between the trolley and the furnace, through opening 12 and into channels 11. The hollow blocks 4 may be open top and bottom to allow circulation of hot gases within the wall. The blocks may be held together with motor or they may interlock, e.g. as shown in Fig. 4.

Title: Improvements in or relating to electrical capacitors
IPC: H01G4/015
Filed: 1962-08-15
Abstract: 966,538. Capacitors. SIEMENS & HALSKE A.G. Aug. 15, 1962 [Aug. 24, 1961], No. 31262/62. Drawings to Specification. Heading H1M. A capacitor formed from metal layers alternately separated by two different thicknesses of dielectric, the dielectric consisting of varnish layers, has the metal layers vaporized on to those varnish layers which form the or part of the thicker layer of the intervening dielectric. In a method of making such a capacitor a first composite strip is prepared by applying a varnish layer to a paper strip, then vapour depositing an aluminium layer on the varnish layer and applying a further varnish layer on the aluminium layer. The two varnish layers and the aluminium layer are stripped from the paper to provide the composite strip required. A second composite strip is prepared similarly, but need only combine the aluminium layer with one varnish layer. The two composite strips are wound together into a roll with the metal layer of the second strip against the second varnish layer of the first strip, the thickness of this varnish layer being less than that of the combined thickness of the varnish layer of the second strip and the first varnish layer of the first strip. An alternative method using a more complicated second composite strip but constructed similarly is also described. The object of the arrangement is to provide a capacitor which has a high specific capacitance per unit volume.

Title: Method and apparatus for Accomplishing Blank Area Skipping in a Facsimile System
IPC: H04N1/17
Filed: 1966-07-12
Abstract: 1,159,401. Facsimile systems. XEROX CORP. 12 July, 1966 [14 July, 1965], No. 31352/66. Heading H4F. In a facsimile scanning system the absence of information (e.g. the absence of black lettering on a white background) in a line or in portion of a line on the original is utilized to cause the video signal generating scanning means to "skip-over" such line whilst the presence of information allows normal operation to continue. Thus, as shown, the original is carried by a rotating drum and scanned by three heads 25-1, 25-2, 25-3 the outputs of which are selectively utilized by a logic network 27 such that two of the heads act as pre-scan heads for each line whilst the output of the third constitutes the video signal which is transmitted to the receiver printer together with signals identifying such head. The operation is as follows. Assuming head 25-1 to be producing video signals as the result of information being present in that portion of a line (one third) scanned by it and if during this one third revolution of the drum no information is sensed by head 25-2 only the output from the latter head is then utilized for transmission and heads 25-1 and 25-3 are utilized as pre-scan heads. If, however, no information is sensed by heads 25-2 and 25-3, the head 25-2 output is utilized for transmission and a line advance signal is generated by the network 27. If no information is sensed by head 25-3 only, the operation continues unchanced. The video signals, head identification signals and line advance signals are transmitted in multiplex fashion to the receiver and utilized to control the operation of a printer to reproduce the required facsimile.

An enclosure 1 is cooled by the evaporator 2 of a closed evaporating-condensing system the condenser 5 of which is cooled by blocks 6 of solid Co 2 , a circulating pump 11 being provided in the system. The blocks 6 are immersed in a liquid 7, e.g. the higher alcohols or methylene chloride, in an insulated tank 4 having double walls which form the condenser 5. When it becomes necessary to defrost evaporator 2 or when it is desied to heat the enclosure, valves 12 and 13 are operated to connect a heat exchanger 14 in the circuit in place of the condenser 5 and pump 11. Heat exchanger 14 is associated with a heat source, e.g. a vehicle exhaust, ambient air, an electric heater or the cooling water circuit of a vehicle, and now functions as the evaporator of the system with former evaporator 2 as the condenser. The vapour from the evaporating Co 2  may be used to provide the power for the pump 11 and for a fan 3 in the compartment, in which case the vapour is led from the tank 4, heated and expanded in an expansion machine (Fig. 2, not shown). The cooled, expanded Co 2  may be supplied to the compartment 1 or to its insulation.
