    • 846,605. Lamps combined with key holders. SEGER, E. Jan. 14, 1959 [Jan. 17, 1958], No. 1729/58. Class 39(2). [Also in Group XXV] A key comprises a retaining member 13 which is intended to reach through perforations in the keys and is held in a flexible envelope 10 and the envelope is adapted to cover the keys and also houses a switch controlled torch 12 operated by a dry battery. As shown, the retaining member 13 is a rod secured at one end to one part of the envelope 10 by a head 15 and having a detachable head 16 at the other end by which another part of the envelope may be lifted clear of the rod to remove or refit a key thereto. The envelope is adapted to be folded double around the keys and to be fastened by a snap fastener 17, 18. The torch is located in a housing 11 and comprises a metal casing 20 closed by an insulated bulb cover 19, and an electric battery 24, the centre contact 25 of which is held off the centre contact of the bulb 22 by a spring 23 which engages the other contact of the bulb and the metal casing of the battery. The torch is operated by a push switch 21. In a modification Figs. 4-6 (not shown), the member 13 is constituted by a plate carrying spring clips each of which engages a key perforation.

    • A contactless rotary shaft position sensor provides for precision computation of shaft angle for a wide range of input shaft rotational angles. The sensor includes two annular two-pole magnets which are connected by a precision, motion-transmitting gear train. An optional second gear train between one of the magnets and the input shaft can provide additional angular rotation scaling to accurately measure either fractional or a large number of multiple turns of the input shaft. The gear ratios are selected such that one of the magnets does not rotate more than one revolution. Pairs of ratiometric Hall-effect or magnetoresistive sensors provide differential voltage signals which are used for sensing angular position of each magnet over a full 360 degrees of rotation. The single-turn magnet provides an absolute, coarse indication of input shaft rotation with a typical accuracy of 2%. The gear ratio between the magnets produces several turns of the second magnet for each turn of the single-turn magnet. Since the gear ratio between the magnets is fixed, the angle sensed for the multi-turn magnet can be predicted from the position of the single-turn magnet. This is compared to the multi-turn magnet's actual sensed rotation. The result is an improvement in accuracy directly proportional to the gear ratio between the magnets. Computation of the individual magnet rotation angles and the input shaft angle is performed using a microprocessor and appropriate signal conditioning circuits. Utilizing two magnets, input shaft rotation can be accurately measured to within 0.1% of maximum range.
    • 非接触式旋转轴位置传感器可以在宽范围的输入轴旋转角度下精确计算轴角。 该传感器包括两个通过精密的运动传动齿轮系连接的环形两极磁体。 在一个磁体和输入轴之间的可选的第二齿轮系可以提供额外的角度旋转缩放以精确地测量输入轴的分数或多个匝数。 选择齿轮比使得一个磁体不旋转超过一圈。 成对的霍尔效应或磁阻传感器提供差分电压信号,用于检测每个磁体在全360度旋转角度的位置。 单转磁铁提供绝对粗略的输入轴旋转指示,典型精度为2%。 磁铁之间的齿轮比对于单匝磁铁的每一圈产生第二磁体的几圈。 由于磁体之间的传动比是固定的,所以可以从单匝磁体的位置预测多匝磁体感测到的角度。 这与多圈磁铁的实际感测旋转相比较。 结果是与磁体之间的传动比成正比的精度提高。 使用微处理器和适当的信号调节电路来执行单个磁体旋转角度和输入轴角度的计算。 利用两个磁体,输入轴的旋转精度可以在最大范围的0.1%以内。

    • A display case for a replacement window, comprising a case assembly and frame member. The case assembly has a front panel and a rear panel hingedly connected to each other near their top edges, and having an inwardly directed flange connected to their side edges. The frame member secures a replacement window therein and is slidably inserted within the case assembly. The frame member comprises two side sections, a top section and a bottom section. Each side section has at least one longitudinally-extending channel on its external surface for sliding engagement with a flange on the case assembly. The case assembly has means for preventing opening of the hinged connection beyond a predetermined maximum point. There is a plank attached to said bottom section of the frame and extending along its length. The plank has outwardly beveled longitudinal edges so as to create a groove between the bottom section of the frame and the bottom of each beveled edge. Sliding the frame out of the case assembly and opening the hinged connections to their maximum point causes the top edges of the panels to engage the grooves and lock the frame in an extended position. Closing the panels releases the grooves and allows the frame to slide within the case assembly for transportation and storage.
    • 一种用于更换窗的展示柜,包括一壳体组件和一框架构件。 壳体组件具有在其顶部边缘附近彼此铰接地连接的前面板和后面板,并且具有连接到其侧边缘的向内凸缘。 框架构件将替换窗口固定在其中,并且可滑动地插入到壳体组件内。 框架构件包括两个侧部,顶部和底部。 每个侧部分在其外表面上具有至少一个纵向延伸的通道,用于与壳体组件上的凸缘滑动接合。 壳体组件具有用于防止铰链连接超过预定最大点的打开的装置。 有一个板条附着在框架的底部并沿其长度延伸。 板条具有向外倾斜的纵向边缘,以便在框架的底部部分和每个倾斜边缘的底部之间形成凹槽。 将框架从壳体组件中滑出并将铰接连接件打开至最大点使得面板的顶部边缘与凹槽接合并将框架锁定在延伸位置。 关闭面板释放凹槽并允许框架在壳体组件内滑动以便运输和存储。
