    • Apparatus and method is provided for reliably testing a quality level of bead fusion in molded foam parts. Such apparatus may be portable and hand-held, and the test procedure will not destroy or damage tested products. In a useful embodiment comprising apparatus for monitoring quality of a molded foam part, an insertion device introduces a stream of selected gas under pressure into the interior of the molded foam part. The insertion device may include a thin nozzle to be inserted into the part. Poorly fused beads allow a faster flow rate of the gas than well fused beads, since the poor fusion will provide more openings for the gas to escape. Accordingly, the embodiment includes a sensor for measuring the flow rate of the stream of gas, as the stream is introduced into the part interior. An indicator mechanism, responsive to operation of the flow sensor, provides notice to a user of the apparatus that the gas flow rate does or does not exceed a pre-specified level, which indicates a corresponding level of part quality.
    • 提供了用于可靠地测试模制泡沫部件中的珠粒熔合的质量水平的装置和方法。 这样的设备可以是便携式和手持式的,并且测试程序不会破坏或损坏测试的产品。 在包括用于监测模制泡沫部件的质量的装置的有用实施例中,插入装置将压力下的选定气体流引入模制泡沫部件的内部。 插入装置可以包括要插入到该部件中的细喷嘴。 由于不良融合将为气体逸出提供更多的开口,所以较不熔融的珠允许气体比熔融珠更快的流速。 因此,该实施例包括用于测量气流的流量的传感器,因为流被引入到部件内部。 响应于流量传感器的操作的指示器机构向设备的用户通知气体流量是否超过预定水平,其指示相应的零件质量水平。

    • A method and system is presented for ensuring that a latch securing a ramp to a pallet is properly aligned and seated before a product can be offloaded from the pallet and down the ramp. The system uses a latching system that has a pallet-attached base and a ramp-attached mating bracket. The pallet-attached base has two rods. The first rod has a retainer arm that is restricted by the second rod to a vertical position, thus preventing a shipment on the pallet from reaching the ramp. The second rod has a thin portion and a thick portion. The second rod must be laterally moved such that the mating bracket mates only with the thin portion of the rod. This lateral movement moves the second rod away from the first rod's retainer arm, thus allowing the retainer arm to fold down.
    • 提出了一种方法和系统,用于确保在将货物从托盘卸下并沿着斜坡卸下产品之前,将固定斜盘的闩锁正确对准和安置。 该系统使用一个闩锁系统,该系统具有一个托盘附接的底座和一个斜坡连接的配合支架。 托盘安装底座有两根杆。 第一杆具有由第二杆限制到垂直位置的保持臂,从而防止托盘上的货物到达斜坡。 第二杆具有薄的部分和较厚的部分。 第二杆必须横向移动,使得配合支架仅与杆的薄部配合。 该横向运动使第二杆移动离开第一杆的保持臂,从而允许保持臂折叠。
