  • Patent number: 4290219
    Abstract: A rifle having a telescopic sight has apparatus for recording the target as seen through the telescopic sight at the instant the trigger is pulled. The apparatus includes a beam splitter for directing to a camera some of the light passing through the telescopic sight. The shutter mechanism of the camera is coupled to the rifle trigger so that the camera will "shoot" the picture of the target when the trigger is pulled. The camera is of the instant-copy type so that pictures of the target can be viewed shortly after "shooting". The apparatus thus enables the ability of a rifleman to be tested without the need for firing live ammunition.

  • Patent number: 4228794
    Abstract: A massager comprises a dumbbell-shaped housing having a relatively large upper part, a narrow intermediate part, and a relatively large lower part. An electric motor is housed in the upper part and has an at least partially flexible shaft extending through the intermediate part and connected via a transmission in the lower part to massage fingers extending axially from this lower part. A fan mounted on this shaft in the intermediate portion sucks air in through slots through which the massage fingers extend, moves it axially through the housing, and expels it from holes in the upper end of the housing.
