Abstract: ORAL PROSTHESIS AND METHOD FOR PRODUCING SAME          ABSTRACT           A porous implantable oral prosthesis which can be used to replicate and replace any hard tissue portion of the mouth such as bone and teeth is described.          The prosthesis comprises sintered polymeric particles coated with a hydrophilic material.  The polymeric particles vary in size so as to provide an area of rela-tively coarse porosity where the prosthesis is intended to interface with bone tissue and relatively fine porosity where it is intended to interface with soft tissue.  A process for producing such prosthesis by filling a mold with appropriate molding compounds comprised of polymeric particles and a hydrophilic monomer, sintering the particles and polymerizing the monomer by dielectric heating, removing the sintered material from the cooled mold, and placing the prosthesis in a hot liquid to remove residues is described.  An entire tooth, including a nonporous crown may be produced.  A process for producing a porous replica of a tooth root suitable for implantation immediately after extraction of a tooth is disclosed.          When extraction has taken place in the past and has resulted in the bone and gum receding, a porous implant inserted in a newly drilled hole in the patient's jaw bone may be used.  A central post associated with the implant projecting above the gum may be used for attaching a denture, partial bridge or a crown.  A porous implant may be used for jaw bone replacement in order to improve the fitting of dentures.

Abstract: ABSTRACT   A flat type display apparatus includes an electron beam source for emitting a row of a large number of electron beams, and a phosphor screen having a phosphor layer which emits light in response to impingement by the electron beams.  An electron beam convergence means is provided and an electrostatic deflection means for deflecting the electron beams prior to impingement on the phosphor screen.  An electron beam controlling means has a number of electron beam controlling electrodes for individually controlling the current of the electron beams to control light emissions from the phosphor screen.  A pulse width modulation circuit feeds electron control signals of a constant voltage and pulse-width modulated by video signal information to be displayed.  Light emission control without changing converging conditions of electrostatic lenses is thus obtained so that a good linearity between the video signals and the electron beams is obtained.

Abstract: Abstract of the Disclosure This specification discloses an absolute pressure sensor and measuring technique using an electrochemical apparatus as a feedback element in an oscillator circuit. The sensor needs no reference pressure or reference vacuum. Contributing to sustained oscillation is a phase shift caused by the electrochemical apparatus.  The period of oscillation of the oscillator circuit is inversely proportional to the diffusion coefficient of oxygen in its carrier gas, which, in turn, is inversely proportional to total absolute pressure.  The result is that the period of oscillation of the oscillator circuit is proportional to total absolute pressure.

Abstract: ABSTRACT OF THE DISCLOSURE A circuit for controlling the voltage applied to a glow plug used to assist the starting of a diesel engine, the circuit including a circuit network composed of a normally-closed relay contact connected in parallel with a serially connected voltage-dropping resistor and a nor-mally-open relay contact, the circuit being serially con-nected with the heating element of the glow plug and with a power supply for producing the voltage, and a timer connected to the power supply.  The normally-closed relay contact is opened when the temperature of the heating ele-ment exceeds a preset value which is below a steady-state heating temperature, and the normally-open relay contact is closed by the timer a predetermined time after voltage is applied to the glow plug, whereby the glow plug is heated rapidly.  In the event of an abnormal rise in power supply voltage during the rapid heating of the glow plug, the supply of current to the glow plug is interrupted temporarily to prevent glow plug burn-out.

Abstract: ABSTRACT TELEVISION SYSTEMS AND SUBSYSTEMS THEREFOR       An image is scanned by a color camera (800-808) and the luminance representative signals (e.g. Green) of pairs of adjacent lines are summed and differenced in a processor 861.  Color signals R,G,B and the sum signal (GS) are matrixed to form chrominance components and luminance components of a standard composite video signal (e.g. I,Q, YS for NTSC) in a matrix 812.  One of the chrominance components (I) is comb filtered (1112) to remove portions of its frequency spectrum.  The difference signal (G  ) is comb filtered (1122) to be inserted (1124) into the removed portions of the chrominance component (Fig.11). In a compatible high definition system first ones (L1,L2) of the pairs of lines conform to a standard TV system (e.g. NTSC) and the second ones (L1A,L2A) are offset by e.g. ? of the standard interline spacing.  In an example of the high definition system, the pairs of lines are sampled by a sinusoidal scanning path the samples from the lines being derived by a synchronous switch (618) (Fig. 6).  The difference signal (G   ) is invisible on a conventional receiver but allows high vertical defin-ition on a high definition receiver.

Abstract: ABSTRACT An optical arrangement is disclosed which provides color selective prepolarization of the light incident upon two or more light valves.  In the preferred embodi-ment, this is accomplished by the use of a prepolarizing prism which acts on light from a light source to direct light of a first polarization to a first dichroic separator and light of a second polarization to a second dichroic separator.  Each separator transmits an output beam having substantially a single color and a single polarization state.  The two resulting beams are recombined by a dichroic adder prior to being applied to a second polarizing prism.  The second polarizing prism directs light of a first color and polarization to a first light valve and light of a second color and polarization to a second valve.  The result is that one light valve sees light of a first color and a first polarization and the other light valve sees light of a second color and second polarization.  Each light valve modulates the polarization state of incident light in accordance with the input or writing light.  Where the writing light is present, the polarization state is changed from the first to the second or vice versa depending upon the light valve.  The output of each light valve is applied to a second or main polarizing prism which converts the modulations of polarization into modulations of brightness.  The output of the main polarizing prism is then applied to a projection lens in a conventional manner.

Abstract: Abstract Virtually caffeine-free coffee bean extract sub-stances are restored into coffee beans which have been extracted with an aqueous liquid and thereby decaffeinated. The swollen extracted beans are brought directly into contact, without intermediate drying, with a concentrated, decaffeinated aqueous coffee extract.  The amount of this coffee extract is greater than the amount which the extracted beans are capable of absorbing.  The extract content of the beans is thereby brought almost to the extract content of non-extracted coffee beans, virtually without its caffeine content being increased.  The excess coffee extract is removed from the coffee beans.  It can be recycled to the process again.

Abstract: Abstract Minimization Of The Effects Of Yaw Oscillations In Wind Turbines Yaw (fishtail) oscillations in large wind turbines (10) are minimized by damping provided by a drive motor (65) connecting the turbine to the supporting tower (50) therefor at, for example, a yaw bearing (45).  The drive motor drives the wind turbine in yaw and maintains desired yaw settings of the turbine.  The motor is also capable of being driven by yaw oscillations of the wind turbine and in being so driven, dissipates the energy of such oscillations.
