Abstract: A power driven hair trimmer appliance is fitted with a demountable comb attachment having a supporting segment of similar but larger configuration than the appliance. A plurality of discrete pressure pads are provided for fitting the comb to the appliance so that the comb may be adjusted to any position between predetermined maximum and minimum positions of trim length. At any operating position of the comb, trimmed hair will fall away from the appliance thereby eliminating the need to periodically interrupt trimming operations for cleaning the appliance.

Abstract: A light responsive, battery operated fragrance device is described. The device establishes an air stream over a fragrant material when an artificial light source such as a room lamp is energized. It includes a swivel light gathering body and a photo transistor mounted thereto which can be aimed at the artificial light source and provides directional discrimination and screening of other light sources. The unactuated device provides a limited flow of convection air current which maintains a relatively low level of fragrance dispersion in a room therefor. Upon actuation forced air flowing through the device causes a rapid increase in the level of fragrance dispersion in the room.

Abstract: An improved buoyant alarm device which provides an indication of a disturbance to a quiescent level of a body of water. The device includes a cover assembly and a buoyant body. The cover assembly includes a cover member and a support member. The support member provides a subassembly support for electrical components which are mounted thereto and for forming, with the cover member, an enclosed water-tight chamber for housing the electrical components.
