    • A retaining system (1) that retains the front portion of a cable (7) in a connector housing (3). A sleeve device (21) has a base (25) with a hole (34) through which the cable extends, and has a pair of arms (27) with part-cylindrical inner surfaces that press against the cable to grip it. The arms have rear ends with recess (31). When the sleeve device is pushed fully forward into the connector housing, a bridging device (23) is pushed through an opening (15) into the housing. Legs (37) of the bridging element are inserted into the arm recesses (31) and prevent pull-out of the sleeve device and cable.
    • 一种将电缆(7)的前部保持在连接器壳体(3)中的保持系统(1)。 套筒装置(21)具有带孔(34)的基座(25),电缆延伸通过该基座(25),并具有一对具有部分圆柱形内表面的臂(27),该部分圆柱形内表面压靠电缆以夹持它。 臂具有带凹部(31)的后端。 当套筒装置完全向前推入连接器壳体中时,桥接装置(23)被推动通过开口(15)进入壳体。 桥接元件的腿部(37)插入到臂凹部(31)中,并且防止套筒装置和电缆的拉出。

    • A system for launching an unmanned aerial vehicle (UAV) payload includes a launch tube, liquid rocket, and launch control assembly. The rocket is positioned in the launch tube and contains the UAV payload. A booster assembly may include a canister partially filled with liquid. A gas cylinder is filled with compressed gas. The liquid is pre-pressurized by the gas or mixed with the gas right before launch such that, upon launch, liquid and gaseous thrust stages launch the rocket to a threshold altitude. The UAV payload deploys after reaching the threshold altitude. Optional stability tubes may be connected to the launch tube, which may be buoyant for water-based operations. An optional tether may be connected to the liquid rocket for arresting its flight prior to reaching apogee. The UAV payload is not launched directly by the gas/liquid mix. A method of launching the UAV payload is also disclosed.
    • 用于发射无人机(UAV)有效载荷的系统包括发射管,液体火箭和发射控制组件。 火箭定位在发射管中,并包含无人机的有效载荷。 增压组件可以包括部分地填充有液体的罐。 气瓶内充满压缩气体。 液体被气体预加压或在发射前与气体混合,使得在发射时,液体和气体推进阶段将火箭发射到阈值高度。 无人机有效载荷在达到阈值高度后部署。 可选的稳定管可以连接到发射管,其可以浮动用于水基操作。 可选的系绳可以连接到液体火箭,以在达到远地点之前停止其飞行。 无人机有效载荷不直接由气/液混合发射。 还公开了一种启动无人机有效载荷的方法。

    • The present invention relates to a mesalamine rectal suppository designed to provide improved comfort of use. One embodiment of the invention is a mesalamine rectal suppository comprising mesalamine and one or more pharmaceutically acceptable excipients, wherein the drug load of the suppository ranges from 35% to 50%. Yet another embodiment of the invention is a mesalamine rectal suppository comprising mesalamine having a tap density ranging from about 600 to about 800 g/L (as measured by USP ) and a hard fat having an ascending melting point of 32 to 35.5° C. Yet another embodiment is a mesalamine rectal suppository comprising mesalamine particles and one or more pharmaceutically acceptable excipients, where the mesalamine particles have a surface area of from about 0.1 m2/g to about 2.8 m2/g (e.g., from about 0.1 m2/g to about 1.3 m2/g). Methods of preparing and methods of treatment with mesalamine suppositories are also provided. The invention further provides a method of determining a dissolution parameter (such as dissolution rate) of a mesalamine rectal suppository, such as a 1 g mesalamine suppository, by measuring its dissolution with USP Apparatus #2 at 40° C. and a paddle rotation speed of 125 rpm in 0.2 M phosphate buffer at a pH of 7.5.
    • 本发明涉及美沙拉坦直肠栓剂,其旨在提供改善的使用舒适性。 本发明的一个实施方案是美沙拉坦直肠栓剂,其包含美沙拉嗪和一种或多种药学上可接受的赋形剂,其中栓剂的药物负载范围为35%至50%。 本发明的另一个实施方案是美沙拉坦直肠栓剂,其包含振荡密度范围为约600至约800g / L的美沙拉嗪(通过USP <616>测量)和具有上升熔点为32至35.5°的硬脂肪 C.另一个实施方案是美沙拉坦直肠栓剂,其包含美沙拉嗪颗粒和一种或多种药学上可接受的赋形剂,其中美沙拉嗪颗粒的表面积为约0.1m 2 / g至约2.8m 2 / g(例如,约0.1m 2 / g至约1.3m 2 / g)。 还提供了制备方法和美沙拉坦栓剂的治疗方法。 本发明还提供了一种通过用USP装置#2在40℃下测量溶解参数(例如溶解度)来测定美沙拉嗪直肠栓剂如1g美沙胺栓剂的溶出参数(如溶出速率),并且桨叶转速 在pH 7.5的0.2M磷酸盐缓冲液中的125rpm。

    • A rail fence retractor allowing removal of a fence rail engaged with a fence post comprising a blade having a first and second end. The first end of the blade is configured for insertion into a fence post slot having a rail inserted therein. The rail has self-locking tabs which must be depressed for removal of the rail from the fence post slot. The fence rail retractor also has a handle which is attached to the second end of the blade. The handle allows the application of force against handle to fix the position of the handle against the fence post during removal of the rail from the fence post slot. The handle is also useful in carrying the rail fence retractor when not in use. The handles may be also be configured to allow a pair of rail fence retractors to fit or snap together when not in use.
