Title: Day and night anti-glare lens for eye spectacles
Inventor: JOHNSON BERTHULD T
IPC: G02C7/10
Filed: 1990-06-20
Abstract: Page 1 Of 3 An Invention: Day-Night Anti-glare Lens for Eye Spectacles.          AN ABSTRACT     "The usual traditional way to attempt to counter glare from  say  approaching vehicle lights at night, or the sun's rays  at certain times and positions during daylight  hours, has  been by using lightly shaded to darker shaded lenses in both prescription and 'sun glasses' which have been  on  the market  in  various  shapes  and  sizes  for many years. The problem is however that to  effectively  obscure  bothersome glare,dark shaded lenses are required which in turn obscures the  road ahead, which can lead to an accident. My invention solves this problem with special lenses by having a dark yet transparent section  (similar  to  a  camera  film  negative resulting  from  exposure  to  bright light) above the usual area of vision, having a narrow 'window'  section  which  is perpendicular  and at right angles to the base of the shaded section, and proceeding up  from  the  base  of the  shaded section  some  two-thirds  of  the  way. The  said window is positioned laterally directly above the eye(s) when  looking straight ahead. By lowering the head, the windows allows the eyes to see ahead, and by turning the head slightly away fr-om the source of glare, it is obscured in the darkly shaded area beside the said window, allowing an unimpaired view ah-ead."

Inventor: TIPMAN ROBERT N
IPC: B03B9/02
Filed: 1990-07-13
Abstract: A process for treating bitumen froth containing mixtures of a hydrocarbon component, water and solids, comprises heating said bitumen froth to a temperature in the range of about 80°C to about 300°C, preferably in the range of 100°C to 180°C, under pressure of about 150 to about 5000 kPa, preferably in the range of 800 to about 2000 kPa, sufficient to maintain said hydrocarbon component in a liquid phase, passing said heated froth into a plurality of separation stages in series, and gravity settling the solids and water from the hydrocarbon layer while maintaining said elevated temperature and pressure.  A diluent miscible with the bitumen may be mixed with the bitumen froth in an amount of 0 to about 60 per cent by weight of the bitumen, preferably in an amount of 15 to 50 per cent by weight of the bitumen in a mixing stage for preconditioning of the froth prior to each gravity separation stage.  A low molecular weight hydrocarbon diluent, such as typified by naphtha, kerosene, toluene or natural gas condensate, is preferred.

Abstract: ABSTRACT OF THE DISCLOSURE          A speech coding apparatus coupled to a transmission channel includes m (m is an integer greater than 1) coders, m decoders and m or (m - 1) error correcting coders.  The apparatus also includes an evaluation unit which evaluates a quality of each of reproduced speech signals from the input speech signal and the reproduced speech signals and which outputs an evaluated quality of each of the reproduced speech signals.  The quality of each of the reproduced speech signals is evaluated in a state having no transmission error.  A decision unit identifies one of the m coders which provides the reproduced speech signal having a smallest distortion on the basis of the evaluated quality of each of the reproduced speech signals, a current error rate of the transmission channel and error correcting abilities of the error correcting coders, and generates a coder identification number representative of a selected one of the m coders.  An output part outputs a multiplexed transmission signal including the coded speech signal generated by the one of the m coders identified by the decision unit and the error correcting code generated by a corresponding one of the m error correcting coders.

Abstract: ABSTRACT OF THE DISCLOSURE    In a modulation system using an amplitude and a phase of a carrier wave as information such as a QPSK system, a modulation device modifies an input signal series to compensate the nonlinear characteristics of an amplifier located at a later stage, and provides a carrier wave modulated by the modified signal series to the amplifier.  A first arithmetic circuit obtains an amplitude and a phase of an input signal by calculation.  A ROM is set with correction data corresponding to the calculated amplitude so as to compensate the nonlinearity of the amplifier.  A modification value generating circuit and a RAM output an amount of compensation so as to further modify the correction data according to part of an output signal from the amplifier to compensate amplifier characteristic changes due to temperature variations and the like.  A second arithmetic circuit provides a signal series produced from the modified amplitude and phase to a quadrature modulator.

Title: Apparatus for handling of biopsies and samples
Inventor: GILLIARD RENE
IPC: A61B19/00
Filed: 1990-09-26
Abstract: The instrument for handling biopsies and samples comprises a main body (3) of which the form is similar to that of a syringe, a plunger (4), a recoil means (7), and an element (5) for contacting the sample (2). In order to prevent the suction created by the movement of the recoil means (7) from cancelling out the ejection effect, a small calibrated air inlet (8) is provided to compensate for the volume deficit when the sample obstructs the opening (6) of the suction-ejection tube (10). The ejection of the sample by means of a jet of air can therefore take place in all cases from a plunger position which corresponds to the maximum volume.
