Abstract: A facial growth indicator is used to measure the linear distance from an incisal edge of either a permanent or primary maxillary incisor to the intersection of a line constructed from the center of the ear, passing forward through the most anterior point on the soft tissue of the nose. A patient's measurement can be compared to a normal standard expected for a child at his or her particular age. If the child being examined has an abnormal measurement, then further diagnostic tests can be performed on the child.

Abstract: A human forearm prosthesis is disclosed which has attached thereto a device comprising a housing, a knife blade suitable for cutting food, a projection on the knife blade for restraining the travel of the knife blade into the housing when it is desired to retract the knife blade into the housing for storage thereof, and out of the housing when it is desired to extend the knife blade for use of the knife blade for cutting food. Preferably, the knife blade moves into and out of the housing by force of gravity. The travel of the knife blade is restrained by a guide slot which extends substantially the length of the housing and a projection located on or near the back end of the knife blade, which projection travels in the guide slot. The device of the invention has a spring operated knife blade release mechanism that blocks the knife blade from passing out of the housing when it is desired to restrain the blade in retracted position.

The composition is used for treating a neoplastic disease by a process of administering a non-toxic, effective amount of a ligand-carbohydrate-cytotoxic drug conjugate to a human being or animal in need of such a treatment.

Abstract: An improved tremolo device for a stringed musical instrument provides a fixed plate attached to the body portion, a fixed gear rack with teeth, and a movable plate that is slideable with respect to the fixed plate and has a bridge member. A pinion gear having teeth around the circumference thereof is provided to mesh with the teeth of the fixed gear rack and to move in unison with the movable plate. A lever is attached to the pinion gear for rotating the pinion gear to change the tension on the strings. The fixed plate has a slot or groove in the face thereof opposite the body, and the movable plate has a slot or groove in the face thereof opposite the fixed plate to form one or more cavities in which anti-friction bearings are encased. In the operation of the tremolo device of the invention, tension in the strings is decreased by depressing the lever which causes pinion gear to rotate, thereby driving the movable plate to cause the tremolo effect when the musical instrument is played.

Abstract: A process for preparing a lubricating grease in which a bright stock paraffin oil is mixed with 12-hydroxy stearic acid, and the mixture is then heated to a temperature of from about 170 to about 200 degrees Fahrenheit for at least 30 minutes. Thereafter, lithium hydroxide and calcium hydroxide are added to the mixture, and the mixture is then neutralized by heating it to a temperature of from about 360 to about 450 degrees Fahrenheit. The saponified mixture is then comminuted so that at least about 90 weight percent of the particles in it are smaller than 1 micron. To this comminuted mixture is then added another portion of the specified paraffinic bright stock oil.

Abstract: The process of photodynamic therapy (PDT) is conducted by the step of:1) separately encapsulating at least one activation component for said photodynamic therapy process in a liposome;2) injecting a photosensitizer into a human or animal host;3) injecting the liposome encapsulated components systemically into the same human or animal host; and4) heating the site of the tumor to melt the liposome encapsulated components to permit mixing of the activation components.The mixing of the activation components can result in:a) energy transfer to the previously injected photosensitizer;b) emission of light and absorption of said light by the previously injected photosensitizer; andc) direct formation of at least one cytotoxic species that functions against the tumor.The heating of the site of the tumor is accomplished by one of the following methods: laser, ultra sound, radio-frequency or microwave frequency. Photofrin photosensitizer is a preferred photosensitizer.
