Abstract: The invention is an operational amplifier having an output stage for enhancing the output driver capability near the negative source voltage. The output stage of the invention includes a voltage detector in combination with a current redirector or redirecting arrangement. The voltage detector converts the voltage difference between the amplifier output and the input to the output stage of the amplifier to a control current, which is redirected at the positive source voltage and applied to the negative output driver. The current redirector, which is operably connected to the voltage detector, allows the amplifier output to be driven at full rated current (e.g., approximately 40 mA) close to the negative source voltage (e.g., within approximately 1.5 volts) while maintaining an output configuration appropriate for stability.

Abstract: A method, and apparatus for practicing the method, for eliminating the necessity for manually dialing a local area code as a prefix to a call within the same area code in telephone systems in which such action is a requirement. An automatic dialer is activated and immediately transmits the local area code onto the caller's telephone line when an off-hook condition is sensed; e.g., when a telephone handset is picked up. Thus, the caller can merely then dial an ordinary seven digit telephone number within the local area code. In order to provide for the selective dialing of long distance, when the caller "flashes" his line within a predetermined period (typically, a few seconds) after picking it up, a hang-up followed by a second off-hook is emulated; however, the automatic dialer is inhibited from again transmitting the area code. Consequently, the caller is presented with a dial tone, and a telephone number, including an area code which may be different from the local area code, may be successfully dialed.

Abstract: The  invention provides  a method for  arranging  the inking for a pressrun in a rotary printing machine.   The rotary printing machine has  an  inking mechanism  and  a dampening mechanism.   The ink quantity transmitted by an ink ductor is adjusted by zone via ink zone ductor blades. When the dampening mechanism is switched off, the run-up curve of the inking mechanism is initially adjusted at an average surface coverage over the entire surface, so that a  constant  ink  density  corresponding  to  the  average surface coverage results on the printing stock for all printing  speeds.    The  run-up  curve  of  the  dampening mechanism is adjusted subsequently, wherein the ink zone ductor blades are in different positions which correspond to various surface coverage values of a printing subject customarily  printed  by  the  printing  machine.     The adjustment is effected in such a way that the ink zones with  average  surface  coverage  deliver  a  constant  ink density to the printing stock for all printing speeds. The surface coverage in ink zones not having the average surface coverage is measured at different printing speeds. A  measurement  for  the  readjustment  of  the  ink  zone measuring devices is obtained from the deviation of the measured  surface  coverage  from  the  reference  surface coverage.    For  each  of  the  surface  coverage  values, characteristics lines are obtained for the readjustment of the ink zone measuring devices which is dependent on the printing speed.

Granted: 2007-11-13
Abstract: The invention relates to a safety device for truck wheels. An integral member is provided which is retained in an abutting relationship with the axle of the wheel assembly, but the integral member is free of any connection with the wheel studs of the wheel assembly. The abutting relationship may be provided by having a plurality of holes of the integral member which receive a plurality of the axle studs of the axle. Alternatively, the abutting relationship may be provided by providing a sleeve portion on the integral member and an interior threaded portion within that sleeve that is threaded to the axle of the wheel assembly. A lock screw may then be passed through the integral member to retain the member in the abutting relationship with the axle. An advantage of the present invention is that a strong connection is provided between the axle and the safety device, thus making it possible for the safety device to prevent wheels from flying away from a truck, tractor, or trailer when the wheel studs or rim suffer mechanical failure.
