    • A pin display first embodiment utilizes a cammed two differently dimensioned cam to press a pin support forward to make it even or clear it, followed by a flattened portion to enable a pin support to move back into gentle contact with a belt having raised numerals which generally advance based upon a continuously driven motor. A third position on the cam brings the pin support forward to a third, rest position away from the belt and at which the mechanism rests, typically for one minute. The subject matter can be time, temperature, barometric pressure, or for symbols and pictures for a story telling application. The device can be configured to display any dimensional image and can present a sequence of images. A pin display of a second embodiment of the invention utilizes push-pull solenoids to control pre-specified segmented areas of pins to an outward or inward position.
    • 销显示器第一实施例利用凸轮式两个不同尺寸的凸轮来向前按压销支撑以使其均匀或清除它,随后是平坦部分,以使销支撑件能够移动回与具有一般的凸起数字的带的柔性接触 基于连续驱动的电机进行前进。 凸轮上的第三位置使销支撑件向前移动到远离带的第三个静止位置,并且机构在该位置处通常为一分钟。 主题可以是时间,温度,气压或用于故事讲述应用的符号和图片。 该设备可以被配置为显示任何尺寸图像并且可以呈现一系列图像。 本发明的第二实施例的销显示器利用推挽式螺线管来将预定的分段区域的销控制到向外或向内的位置。

    • A manually generatable lighting device utilizes a pull cord, which is mechanically linked to a motor, to charge a power pack for on-demand illumination of at least one light-emitting diode. The lighting device employs circuitry which enables its use as continuous light source, a night light which illuminates automatically in low-light conditions, or an emergency light which illuminates automatically during power failure. The lighting device includes a power plug and may be stored or illuminated portably or as plugged into a power outlet. Built-in charging circuitry allows electrical recharging of the power pack to a maximum of 4 hours of usage, although the pull cord mechanism extends the possible usage time because it allows the power pack to be manually recharged at any time regardless of the level of stored charge available in the power pack. The lighting device requires only minimal effort to achieve maximum brightness, and two complete actuations of the pull cord can achieve maximum charge.
    • 手动可生成的照明装置利用机械地连接到电动机的拉绳来对至少一个发光二极管的按需照明的电源组进行充电。 照明装置采用使其能够用作连续光源的电路,在低光条件下自动照明的夜灯或在断电期间自动照明的应急灯。 照明装置包括电源插头,并且可被携带或插入电源插座中被存储或照明。 内置充电电路允许电源组充电最多4小时,尽管拉绳机构延长了可能的使用时间,因为它允许电源组随时手动充电,而不管存储的水平如何 电源包中可用的电量。 照明装置只需要最小的努力来实现最大亮度,并且拉绳的两次完全致动可以实现最大电荷。

    • A hand held, one touch jar opener can be placed on a jar and activated with a momentary touch of a button. An epicyclic gear train is set to sequentially provide a grip on a jar, and on a lid, followed by development of torque needed to move the lid in a counterclockwise direction with respect to the jar. The principles embodied in the opener shown can be realized in an opener which can be manually powered, or preferably motorized and possibly highly automated. A differential geartrain provides reduction of speed and increase in torque and then provides two balanced and opposing forces through the epicyclic gear assembly having sun and planet gears. This configuration enables a wide variety of screw-on lids and jars to be automatically closed to match the correct diameters, apply a gripping force and then apply torque in an opposing direction.
    • 一只手持式,一触式开瓶器可以放在一个罐子上,激活一下按钮。 设置一个行星齿轮系,以顺序地提供一个把手在一个罐子上,一个盖子上,然后发展相对于这个罐子沿逆时针方向移动盖子所需的扭矩。 所示的开启器中体现的原理可以在开启器中实现,该开启器可以手动动力,或优选地机动化并且可能高度自动化。 差速齿轮系提供速度的降低和扭矩的增加,然后通过具有太阳和行星齿轮的行星齿轮组件提供两个平衡和相反的力。 这种配置可以使各种螺旋盖和罐自动关闭以匹配正确的直径,施加夹紧力,然后在相反的方向施加扭矩。

    • An improved pool vacuum includes a filter cone and poppet valve combination which enables quick drainage of water which has passed through and been cleaned by the cleaner's filter. A charging circuit is provided with isolation so that the pool vacuum can be used in an electrolytic environment without battery drainage. A combination charger and hang bracket enables the pool vacuum to be stored in a vertical position to both drain and charge simultaneously. An interstitial open exhaust gap between a rear body and nose-cone shaped front section provides a low pressure drop free exhaust area for an impeller. An optionally obstructed bottom gap portion helps to produce a net downward thrust to assist in using the vacuum in deep pools from a long pole structure.
    • 改进的池式真空包括过滤锥和提升阀组合,能够快速排出已经通过并被清洁器过滤器清洁的水。 充电电路具有隔离,使得池电真空可以在没有电池排放的电解环境中使用。 组合充电器和悬挂支架可使池式真空储存在垂直位置,同时进行排水和充电。 后体和鼻锥形前部之间的间隙开放排气间隙为叶轮提供了低压降自由的排气区域。 可选地阻塞的底部间隙部分有助于产生净向下的推力以帮助在来自长杆结构的深池中使用真空。
