Title: Scanning system for a beam
IPC: H04N3/08
Filed: 1970-04-21
Abstract: 1,254,664. Scanning systems. SINGERGENERAL PRECISION Inc. April 21, 1970 [May 8, 1969], No. 18962/70. Heading G2J. A beam scanning system wherein a fast scanning speed is achieved by the use of small deflectors comprises two deflectors 30, 32 which are adapted to deflect a light beam 40 successively in two different planes and which are rotatable to effect a scanning motion of the beam on a display 34, together with a lens arrangement 36, 38 for imaging the deflection centre of deflector 30 on to that of deflector 32, the deflection centre being that point about which the beam appears to rotate when deflected. The lenses 36, 38 are so arranged that the front focal point of lens 36 and the rear focal point of lens 38 coincide with the deflection centres of deflectors 30, 32 respectively, and the rear focal point of lens 36 coincides with the front focal point of lens 38 at F. Thus the deflection centre of deflector 30 is imaged on to the deflection centre of deflector 32 so that the images from the rotating deflector 30 are directed to a point on the rotating deflector 32. Hence the deflected beam 40a-40e can be deflected on to display 34 with a large (and rapid) scanning motion by a small deflector 32. Deflector 32 may take the form of a dove prism in order to achieve a spiral scan, and the system may be used to scan with a narrow parallel laser beam.

Title: Mass spectrometric system for rapid automatic and specific identification and quantification of compounds
IPC: G01N27/62
Filed: 1975-05-06
Abstract: 1484742 Mass spectrometers UNIVERSAL MONITOR CORP 6 May 1975 [16 May 1974] 19001/75 Heading HID A mass spectrometer system includes a data analysing system which stores spectral data of known substances being sought and which also stores criteria for judging the presence of these substances (e.g. detection of a certain number of spectral lines typifying a substance): output signals from the mass spectrometer are compared with the stored spectral data and on the basis of the said criteria an indication is given of the presence or absence of substances sought. The presence or absence of a substance can be judged on a probabilistic basis and an indication of confidence in the result can be given. The likelihood of finding a particular line at random can be taken into account. The intensity of spectral lines can be measured to give a quantitative estimate of a substance. The substances sought can be organized in sets and the determination can be based on these sets rather than individual substances. The Specification describes in detail and at some length the various elements of the spectrometer system. The main items described are as follows (none of the Figures is shown here): Figs. 2a and 2b means for injecting samples in a neutral gas into the spectrometer; Figs. 3 and 4 a quadrupole mass spectrometer and a control system and power supply therefor; Fig. 5 a variable gain detector amplifier; Fig. 6 a "peak stretcher" circuit which stores the maximum detector amplifier output in any spectrometer scan; Fig. 7 a block diagram of the analysing system which can be a suitably programmed digital computer and Fig. 8 illustrates a "contracted spectrum" which can be stored in the analysing system this spectrum consisting of selected lines of the full spectrum.

Abstract: 634,590. Preparing fuel. STANDARD FRANCAISE DES PETROLES. July 17, 1947, No.19124. Convention date, July 22, 1946. [Class 50] [Also in Group II] A method of briquetting coal fines comprises feeding the fines into the upper part of a mixing chamber through which they fall by gravity, liquefying a binding agent whose consistency at normal temperatures may range from that of a hard solid to a plastic mass and injecting the liquefied binding agent atomised in a carrier gas downwardly into the lower part of the mixing chamber, whereby there is formed a mist through which the coal fines fall, thus causing intimate contact between the coal fines and binding agent, and, after further mixing, forming the mixture into briquettes. In the apparatus shown, the binder after being liquefied in a boiler, is pumped through a pipe 1, in which is concentrically mounted a pipe 5, fed with steam, air or other gas under pressure, whereby the binder is blown downwardly into the lower part of chamber 2 in the form of a fine mist 6. The powdered coal is fed to the chamber through pipe 4 and falls through the mist 6 to mix intimately with the binder. A revolving blade mixer in the bottom of the chamber completes the mixing, the mixture then being conveyed to a briquetting press. The Specification as open to inspection under Sect. 91 is not limited to the treatment of coal fines and refers to solid and liquid pitches, particularly those from petroleum refining processes, precipitated or natural asphalts, coal tar pitch and petroleum resins, as suitable binding agents. This subject-matter does not appear in the Specification as accepted.

Abstract: 147,432. Ges. f³r Drahtlose Telegraphie. Nov. 9, 1916, [Convention date]. Morse and like recorders; photographic recorders; automatic telegraphs.-The paper strip ordinarily used for reception and transmission in code telegraphy is replaced by a textile thread. As shown in Fig. 1, the receiving-instrument comprises a thread 1 wound from a spool 3 on to a spool 4 and passing across the rim of a roller 7 dipping into a trough of coloured ink. An electro-magnet energized by the received signals has its armature mounted on a blade 8 which presses the thread on to the roller 7, thereby impressing the Morse signals on the thread. Alternatively, the thread may be coated or impregnated with a light-sensitive substance, and the signals photographically recorded by arranging the receiving-instrument to direct a beam of light thereon. For transmission, either the crosssection or the conductivity of the thread is varied in accordance with the signals. In the first case the thread acts mechanically on a spring contact. and in the second case the thread is passed between two rollers connected in circuit with a battery and relay. The variation in conductivity of the thread may be effected by impregnating it with a conducting liquid, or by depositing metallic dust on it by a spray &c.
