    摘要： A fixture and method is provided for in vitro storage of a cornea. The fixture includes a platform having a corneal-sceral rim receiving surface, a clamp having a mating surface for the cornel-scleral rim and handles. A locking mechanism is provided to secure a donor cornea between the clamp and platform. The combination cornea, platform and clamp are placed in a storage unit having a fluid preservation media. In one embodiment, the storage unit includes a vial having an optically clear closed end and an opened end. A lid is secured to the open end of the vial and engages the handles in order to stabilize the clamped cornea within the vial.

    摘要： The plotter stylus has a writing point (10) which is connected to the ink cartridge (50) via the ink duct (40). The ink duct (40) is surrounded by a pressure compensator (20) and connected thereto. In the pressure compensator a compensator element (21) is provided with annular chambers (23) which absorb surplus ink emerging from the ink duct (40) in the case of temperature or pressure increases. The annular chambers have no capillarity for the ink. Air is introduced via the air inlet orifice (28) located above the chambers (23). The ink cartridge (50) is exchangeable.

    摘要： The discharge end of a supply conduit for a mixture of tobacco particles and air communicates with the top portion of a hollow cylindrical housing for a driven cell wheel whose cells are subdivided into inner and outer chambers by impermeable partitions. The outer chamber of each preceding cell communicates with the inner chamber of the respective next-following cell by way of a sieve which forms part of the corresponding vane of the cell wheel. The outlet for tobacco particles is disposed at the lowermost point of the housing and communicates with successive outer chambers, the same as the discharge end of the supply conduit. A suction pipe for evacuation of gaseous carrier medium has an intake end which is coaxial with the wheel and communicates with successive inner chambers at a level above the axis of the wheel so that the inner chambers of cells whose outer chambers discharge tobacco particles into the outlet are sealed from the suction pipe. The discharge end of the supply conduit has a wall portion which deflects particles of tobacco onto successive partitions of the wheel. A pipe for admission of compressed air which cleans the sieves communicates with successive inner chambers in the region of the outlet for tobacco particles.

    摘要： A filter cigarette making machine wherein two plain cigarettes of unit length are connected to a coaxial filter plug of double unit length therebetween by an adhesive-coated uniting band which is convoluted around the filter plug and the inner ends of the plain cigarettes. The machine has a rotary drum-shaped draping conveyor and a heated stationary block-shaped rolling device adjacent to the peripheral surface of the conveyor to normally define therewith a gap of a width slightly less than the diameter of a group consisting of two coaxial plain cigarettes and a filter plug therebetween. Successive groups, each of which carries a non-convoluted uniting band, are fed into the gap by moving sideways whereby the groups roll about their own axes and the uniting bands are converted into tubular envelopes. A parallel motion automatically retracts the rolling device from the draping conveyor when the prime mover of the machine is arrested whereby the groups between the conveyor and the rolling device are free to leave the machine by gravity. This insures that filter plugs which are sensitive to heat cannot adhere to or contaminate the peripheral surface of the draping conveyor and/or the adjacent surface of the rolling device. The parallel motion is actuated by a double-acting pneumatic cylinder and piston unit which receives pressurized fluid by way of a valve whose solenoid is controlled by a tachometer generator which monitors the speed of the draping conveyor.

    摘要翻译： 一种过滤嘴香烟制造机，其中两个单位长度的平烟香烟通过粘合剂涂覆的联接带连接到双组分长度的同轴过滤塞，该粘合带围绕过滤嘴和平烟卷烟的内端卷绕。 该机器具有旋转滚筒形悬垂输送机和与输送机周边表面相邻的加热的固定块状滚动装置，以通常限定宽度略小于由两根同轴平卷烟组成的组的直径的间隙 和它们之间的过滤塞。 每个带有非卷积的联合带的连续组通过侧向移动而被馈送到间隙中，由此组围绕其自身的轴线旋转，并且联合带被转换成管状包封。 当机器的原动机停止时，平行运动自动地将滚动装置从悬垂输送机中缩回，由此输送机和滚动装置之间的组件可以通过重力自由离开机器。 这确保了对热敏感的过滤塞不能粘附或污染覆盖输送机和/或滚动装置的相邻表面的周边表面。 平行运动由双作用气动缸和活塞单元致动，气动缸和活塞单元通过阀门接收加压流体，其中螺线管由转速计发生器控制，该转速计发生器监控悬垂输送机的速度。
