Abstract: An optical system for a periscope-like sighting device is proposed for the localization, tracking and measurement of a target and comprises a plurality of optical elements as well as a laser range-finder essentially comprising transmitter and receiver portions. In this optical system, the visible and invisible radiation mutually parallelly incident upon a main mirror rotatable about a first axis and pivotable about a second axis is reflected to a first deflection prism. The first deflection prism deflects the radiation at substantially right angles through an objective lens to a first beam-splitter. The first beam-splitter deflects the invisible laser radiation to the receiver portion and transmits the visible radiation to a second beam-splitter and thence to a second deflection prism and an ocular. For achieving a view of the field of observation or a tracking of the target, or both, a television camera can be arranged on the side of the housing of the sighting device.

Abstract: An explosive powder charge operated tool for driving nails includes a housing with a muzzle part mounted in and projecting axially outwardly from the housing. By moving the muzzle part rearwardly into the housing, the tool is in the ready-to-fire condition. A magazine is supported at one end within the muzzle part and extends generally radially outwardly from it. A slide in the magazine feeds individual nails in a nail strip into the bore in muzzle part into position to be driven by a piston located within the housing. When all of the nails in the strip have been driven from the tool, one end of the strip projects into the muzzle bore. A stop shoulder on the one end of the strip faces toward an end face on the housing and contacts the end face when the muzzle part is pressed into the housing, preventing the placement of the tool in the ready-to-fire condition.

Inventor: SPARKS BRADLEY ALAN
IPC: H04N5/44
Filed: 1990-03-22
Abstract: A receiver comprises a synthesizing tuner circuit (22) for detecting a selected input signal and an audio circuit for reproducing the audio content in the detected signal. The tuner circuit includes a local oscillator (54), a prescaler, a phase locked loop (70) and an integrator (92, 94), and has a tendency to uncontrollably detune during AC power interruption and generate audible noise during the detuning. The audible noise is introduced into the audio content of the detected signal. An AC power interruption detector monitors a run power supply and generates a control signal when the run supply falls below a predetermined threshold. A control circuit (12, 84) responsive to the control signal first disables normal operation of the tuner circuit and then disables the audio circuit, thereby reducing the audible noise. The tuner circuit may be disabled by decoupling the output of the phase locked loop from the input to the integrator, enabling the input to float. In the absence of a corrective signal from the phase locked loop, the integrator maintains a substantially constant output tuning voltage and prevents sudden detuning.
