    摘要： An indicating instrument having at the front of its casing a bezel surrounding the front window, and having illuminating lamps within the casing. The bezel has one or several small removable cover pieces or plugs which, when removed, carry with them the illuminating lamps. The sockets for the lamps remain in the instrument, the removed lamps being readily accessible for replacement without requiring dismantling of the instrument casing.

    摘要： AN ELECTRICALLY-OPERATED "ON-OFF" INDICATOR COMPRISING AN ELECTROMAGNET HAVING BETWEEN ITS POLES A ROTATABLE PERMANENT MAGNET CONNECTED TO AN INDICIA-CARRYING ROTARY DRUM. THE PERMANENT MAGNET AND DRUM ARE ON A CENTRAL BUSHING CARRYING BEARINGS THROUGH WHICH A SHAFT EXTENDS. THE ENDS OF THE SHAFT ARE DISPOSED IN ALIGNED HOLES IN THE LEGS OF A U-SHAPED INTEGRAL FRAME BETWEEN WHICH THE DRUM AND MAGNET ARE LOCATED. THE FRAME AND THE ELECTROMAGNET ARE CLAMPED TO A PLASTIC MOUNTING BLOCK WHICH, IN CONJUNCTION WITH THE U-FRAME, MAKE FOR AN EXCEPTIONALLY STURDY AND SHOCK-RESISTANT INSTRUMENT.

    摘要： A clock setting mechanism for automatically and instantaneously shifting the hour hands of clocks forward or backward by a predetermined amount such as an hour for the purpose of complying with semi-annual changes between ''''Standard Time'''' and ''''Daylight Saving Time.'''' In addition to the conventional clock drive mechanism including the friction drive which moves the hour hand, the clock is provided with power-operated driver members which normally are out of engagement with the hour hand assemblage. The hour hand normally turns in the conventional manner. When it is desired to advance or to set back the clock, this being done from a two o''clock (usually A.M.) position, the hour hand is engaged by one of the driver members, utilizing electromagnets and a remote switching control for this purpose, to effect a 1-hour, forward or backward adjustment as required by Daylight or Standard Time.

    摘要翻译： 一种时钟设定机构，用于自动瞬时地将时钟的时针向前或向后移动预定量，例如小时，以便符合“标准时间”和“夏令时间”之间的半年变化。 除了包括移动时针的摩擦驱动器的常规时钟驱动机构之外，时钟还具有通常与时针组合不配合的动力驱动部件。 时针通常以常规方式转动。 当需要前进或后退时钟时，这是从两点（通常是AM）位置完成的，时针由一个驱动器部件接合，利用电磁铁和一个远程切换控制 按照日光或标准时间的要求进行1小时，向前或向后调整。
