摘要： A caller who calls an 800 number is given an audible or visual indication that the call will not incur any charges for services provided on that call by the called party. If such charges will be incurred the caller is warned and may terminate or continue the call. For certain classes of telephone subscribers such as coin stations wherein the caller is not always the same person as the one who pays the bills, calls wherein the caller may incur charges for services provided on the call are automatically routed to an operator; such calls can then be completed using credit or calling cards in order to transfer the charges from the owner of the telephone station to the caller who made the specific call.

摘要： A planar writing surface is attached to a vertically arrangable support panel for engagement next to an automobile console. The support panel has a pair of side edges which each have a vertically adjustable support leg thereon. Each support leg may be independently heightwise adjustable to each touch the floor of the auto next to the console, and provide rigidity to the writing surface. The writing surface panel may flip onto the support panel through an arc of 270 degrees, about its common hinge.

摘要： The security system includes a time dimension in an alpha-numeric personal identification number (PIN) security system to enhance its security yet maintain the familiar and simple to use PIN system. The alpha-numeric digits comprising the PIN are separated into two or more digit groups that must be entered into the system according to a predefined time sequence in order to positively identify the user and provide security clearance. The time sequence can include time delays between the entry of digit groups or time periods during which the digit groups must be entered.

摘要： An apparatus that after a time period settable by the user automatically returns an off-hook telephone to an on-hook condition. This apparatus thus electrically hangs up a telephone handset that is inadvertently left off-hook and allows normal handling of outgoing and incoming calls at other telephone extensions and in some embodiments, even allows calls to ring-in to the telephone having the inadvertently off-hook handset. The apparatus also senses when the inadvertently off-hook handset is returned on-hook and rapidly restores the automatic-return-to-an-on-hook condition switch to normal operation.

摘要： A composite tube for a gun barrel and a method for making the tube are disclosed. The tube includes a plurality of elongate carbon fibers and a resin material surrounding a longitudinal bore axis. The elongate carbon fibers are aligned parallel with the longitudinal bore axis and are under compression along the longitudinal bore axis. Such a tube for a gun barrel may be made by wrapping a tubular metal liner with a resin matrix material containing a plurality of elongate carbon fibers, and aligning the carbon fibers parallel with the longitudinal axis of the liner. The resin matrix material is cured, and the elongate carbon fibers are placed under compression along the longitudinal axis of the liner. Compressing the carbon fibers along the longitudinal axis of the liner produces a tube of surprising stiffness. The tube provides a highly stable gun barrel of reduced weight for good accuracy.
摘要翻译：公开了一种用于枪管的复合管和制造该管的方法。管包括多个细长碳纤维和围绕纵向孔轴线的树脂材料。细长碳纤维与纵向孔轴线平行排列并且沿着纵向孔轴线被压缩。用于枪筒的这种管可以通过用包含多个细长碳纤维的树脂基质材料包裹管状金属衬垫并且使碳纤维与衬套的纵向轴线平行地对准来制造。树脂基体材料被固化，并且细长碳纤维沿着衬套的纵向轴线被压缩。沿着衬套的纵向轴线压缩碳纤维产生了令人惊奇的刚度的管。该管提供了一种高度稳定的枪管，重量更轻，精度更高。
