Abstract: A patient supporting device is disclosed for positioning a patient relative to a substantially flat surface during x-ray diagnosis or radiation therapy to the patient. The device comprises a support having material properties enabling the propagation of the electromagnetic radiation through the support with only minute attenuation of the electromagnetic radiation. The support has a base surface which is adapted for resting on the flat surface. A support surface on the support is adapted to receive the upper torso of the patient for supporting the patient relative to the flat surface. The invention includes a portion of the support surface being movable to position the patient relative to the flat surface. The device may include an aperture defined in the support between the support surface and base surface for receiving a film sensitive to the electromagnetic radiation. The device is suitable for use as a positioning device for elderly people during an x-ray diagnosis.

Abstract: A swimming pool skimming device is disclosed for use with a pool sweeping device connected to a source of water pressure to propel the pool sweeping device within the swimming pool. The invention includes a body member having a specific gravity substantially less than one enabling the body member to provide buoyancy. The body member has a central cavity communicating with an open bottom in the body member. Means are provided for rigidily mounting the body member to the surface unit of the pool sweeping device to provide floatation thereto. A filter is established relative to the open body member with a plurality of water inputs communicating with the central cavity of the body member to enable surface water of the swimming pool to enter the central cavity and to exit through the open bottom with the filter collecting debris accompanying the surface water.
