摘要： A furnace for wood log fuel having apparatus which automatically inserts the logs into the furnace combustion chamber. The log fuel is retained in a sloping ramp storage compartment. Electrical circuitry controlled by a thermostat operates to move a log into an elongated chamber from which a motor driven injector pushes the log into the combustion chamber through a doorway covered by a flexible, segmented flap covering and also a door which is pushed open by the advancing log. The presence of the log on a spring mounted grate operates certain switches to return the injection mechanism to its ready condition and also to operate a fan which provides combustion air to the combustion chamber. The reduced weight on the grate by the consumption of the log by the fire permits the grate to move to a position to re-initiate the log injection cycle. A standby gas fuel burner system is also provided and is controlled by the thermostat to operate when the log fuel heat is insufficient, such as upon the supply of log fuel becoming exhausted. An optional auger conveyor which operates under the control of dual timers for automatic discharge of ashes from the furnace is also disclosed.
摘要翻译：一种用于木材燃料的炉子，其具有将原木自动插入炉燃烧室的装置。原木燃料保留在倾斜的坡道储藏室中。由恒温器控制的电路操作以将原木移动到细长的室中，电动机驱动的喷射器从该腔室通过由柔性分段的挡板覆盖物覆盖的门口推动原木进入燃烧室，并且还通过前进推开的门日志在弹簧安装的格栅上存在木材操作某些开关以将注入机构返回到其就绪状态，并且还操作向燃烧室提供燃烧空气的风扇。通过火灾消耗木材减轻炉排的重量使炉排移动到一个位置以重新启动对数注入循环。备用气体燃料燃烧器系统也被设置并由恒温器控制，以便在对数燃料热量不足时，例如在原料燃料供应耗尽时进行操作。还公开了一种可选择的螺旋输送机，其在双重定时器的控制下操作，用于从炉中自动排出灰分。

摘要： Polyamides comprising substantial amounts of Nylon-11 and/or Nylon-12 units are cross-linked by irradiation in the presence of an unsaturated cross-linking agent, preferably triallyl isocyanurate. The cross-linked products are particularly useful in the form of heat-recoverable shaped articles, e.g. heat-shrinkable tubing.
