Title: 金属空気セルを連結する方法ならびに装置
IPC: H01M50/103
Filed: 1998-05-19
Abstract: (57)【要約】
互いに連結してバッテリスタックを形成するための金属空気セルが提供される。２つ以上のセルが、熱融着または化学的融着により結合されて、バッテリスタックを創成する。金属空気セルの各々は、ケースを有し、このケースは、外面と、負極および空気正極を含むチャンバを画成する内面とを有する。ケースは、空気開口部を画成しており、この空気開口部は、外面と内面との間に延在して、空気を、ケース外部の環境からチャンバ内の空気正極に供給する。１つの実施形態において、各金属空気セルは、複数の突出した連結部材と、複数の突出した機械的止め部とを含む。２つのセルは、一方のセルの連結部材を他方のセルの連結部材に融着することにより結合される。連結部材を融着している間に、結合されるセルの機械的止め部が互いに接触されて、セルの互いに対する移動が抑止される。この抑止により、空間がセル間に均一に画成される。融着された連結部材と、隣接する機械的止め部とが協同して、構造的完全性をもたらす３次元的なトラス状のシステムを画成する。別の実施形態において、連結される２つの金属空気セルの少なくとも１つが、複数の連結部を含み、または止め部を含まない。これらの連結部は、他方のセル上の類似の連結部連結部と位置合わせされかつ融着され、または他方のセルの外面に直接融着されることができる。連結部材および機械的止め部は、好ましくは、それらのケースと一体的に形成され、かつ空気開口部により点在されている。

Title: Packing for valve stem: packing axially compressed between two support rings
Inventor: WILLIAMS P C
IPC: F16K41/02
Filed: 1984-03-23
Abstract: A valve body has a stem passage rotatably receiving a valve stem. A packing surrounds the stem in the passage and a packing nut threaded on the stem applies axial force to radially expand the packing into sealing engagement with the stem and passage wall. Controlled slippage components interposed between the packing and packing nut allow rotation of the stem and packing nut without any rotational sliding movement against an end face of the packing. A packing support ring engages the end face of the packing adjacent the packing nut and includes a chevron surface for radially expanding the packing. A gland engages the support ring and a pair of reversely positioned spring washers are interposed between the gland and packing nut. During rotation of the stem, packing nut and spring washers, the gland rotates against the packing support ring. The chevron surface of the support ring includes notches for gripping the packing to prevent relative sliding movement therebetween. A handle is attached to the stem by a handle nut, and a spring washer interposed between the handle and handle nut prevents loosening of the handle nut.

Title: Latch for tailgate:two simultaneously operating latch members engage lug on tailgate
Inventor: OLINS R C
IPC: B62D27/06
Filed: 1984-03-23
Abstract: A tail-gate assembly comprises a stationary support, a slide mounted on the stationary support, a platform pivotally mounted on the slide, a latch member mounted on and projecting laterally from said loading platform, a latch plate mounted on said stationary support. The latch plate has a latch notch formed therein which has an entrance way opening in a direction to admit the latching member. The notch is proportioned to receive said latch member in a close fitting relationship so as to provide a vertical restraint limiting vertical movement and a rotational restraint limiting rotational movement of said platform. A pair of latching jaws each having a locking tooth at one end thereof, are mounted on the latch plate for pivotal movement between a closed position in which the locking teeth extend inwardly from opposite sides of said entrance way to prevent withdrawal of the latching member from said notch and an open position in which the teeth are displaced outwardly from said entrance way to admit and release the latching member. A closure spring normally urges the jaws toward the closed position, the closure spring is adapted to yield to permit the jaws to open in response to contact with the latch member as it is moved into engagement therewith. An actuator is provided on the jaws which is adapted to cause the jaws to interact with one another whereby movement of one jaw toward the open position causes movement of the other jaw toward the open position.
