Abstract: The improved door lock comprises, in combination, means for engaging a doorknob to releasably grip it and means secured to the doorknob-engaging means and adapted to releasably grip the leading edge of a doorjamb adjacent a doorknob gripped by the doorknob-engaging means. The retaining means prevents the doorknob and the door to which the doorknob is attached from being swung out and away from the lock. The lock is adapted to fit into the corner between the doorjamb and the door and to slide over that doorjamb down into contact and around the doorknob. When it is desired to remove the lock it is merely slid up and away from the doorknob. The lock requires no attachment to either the jamb or the door and can be made in a unitary integral form, preferably generally L-shaped in outline. The doorknob-engaging means can comprise a wall which extends out at right angles to the retaining means which may comprise a plate containing a vertical lip on its front end to engage the leading edge of the doorjamb.

Abstract: An anti-rape device having a hollow housing adapted to be worn within a human vagina. The housing has a front opening and contains a hypodermic syringe having a volume of rape-deterring fluid and a needle facing and aligned with the front opening. Actuator means in the housing are provided which include housing means such as a spring to force the needle through the front opening and inject the fluid, cocking means to cock the device into a position which totally shields the needle within the housing, and prevents action of the spring, and trigger means which automatically releases the cocking means, upon forceful penis penetration of a vagina containing the device, to permit the spring to protrude the needle and inject the fluid into the penis. Preferably, the fluid is a quick-acting, safe narcotic such as scopolamine, or the like to render the rapist unconscious.

Abstract: A portable machine for washing dirt, mud and other types of foreign matter from the surface of golf balls comprising a short cylindrical container whose upper and lower interior surfaces are fitted with roughly textured resilient scrubbing pads and whose upper surface contains a water tight, sealable opening with a hinged snapfast lid providing a means whereby a golf ball may be introduced into the confines of said short cylindrical container and sealed within and whereby water, surfactants and other materials may also be introduced into the confines of the system and through which the entire inner system may be cleansed as needed.
