Title: Gravity motor
Inventor: PAULTON DONALD
IPC: F03G3/00
Filed: 1990-09-24
Abstract: ABSTRACT OF THE DISCLOSURE          A motor which utilizes the force of gravity is disclosed.          The motor comprises two wheels interconnected and a series of spirals  projecting outwardly in the  first larger wheel which spirals accommodate a rollable weight.   The weight is caused to roll by movement of the spiral.  The rolling weight in turn causes rotation of the first larger wheel by means of gravitation which drives the second smaller interconnected wheel.  The second smaller wheel comprises a weight transferring means designed to load and unload the rollable weight on to and off of the spirals of the first larger wheel.   The rotational force of the rotating first larger and  the  second  smaller  wheels  may  be  harnessed  by conventional means.

Title: Projection cathode ray tube having a multilayer optical interference film
Inventor: IWASAKI YASUO
IPC: H01J29/28
Filed: 1991-01-31
Abstract: ABSTRACT OF THE DISCLOSURE     A high-quality projection cathode ray tube for project-ing the image displayed on a fluorescent surface as an enlarged image on a screen in front of the fluorescent surface through a projection lens disposed at a given distance ahead.  On the inner surface of a face panel, a multilayer optical interference film consisting of optical thin film layers of alternately superimposed high refractive and low refracte index materials is provided.  The outermost surface of the multilayer optical interference film is coated with a film of an inorganic material such as silicon dioxide which is optically transparent and stable with respect to the impact of an electron beam.  The thickness of the transparent film is not less than 1.0 µm.   Even an electron beam having a high energy which has passed through the gaps of the phosphor layer loses the energy in this protective film.   Thus, the projection cathode ray tube is capable of reducing the deterioration of the light output with time by suppressing the browning phenomenon of the glass surface of the face panel and the multilayer optical interference film.

Title: Timing apparatus particularly for racing vehicles
Inventor: PENGLASE KIM E
IPC: G04F10/00
Filed: 1990-05-14
Abstract: A timing apparatus for providing timing information to a moving person (11) moving past a datum line (13). A radiation source (15) located at the datum line (13) emits modulated radiation in a diverging conical radiation zone (16) across a path (12) along which the person moves and straddling the datum line (13) across the path (12). A radiation sensor (21) located on an aerial (22) receives radiation emitted by the radiation source (15) as the radiation zone (16) is crossed and generates a sensor signal (21a). A  radiation detector circuit (26) receives the sensor signal (21a) and is tuned to discriminate the modulated radiation from the radiation source (15) and to generate a detector signal (26a) for as long as radiation from the radiation source (15) is being received and detected. A calculator circuit (27) calculates a predetermined proportion of the duration of the radiation zone crossing as represented by the duration of the detector signal (26a) so as to determine the instant of crossing of the datum line (13) and display means (28) display timing information including the time of crossing of the datum line (13).
