Title: Energy beam scanning systems
IPC: G01N21/59
Filed: 1961-11-14
Abstract: 942,227. Sensing record cards. UNITED AIRCRAFT CORPORATION. Nov. 14, 1961 [Dec. 8, 1960], No. 40611/61. Heading G4M. [Also in Division G1] The invention relates to an electro-optical transducer for generating electrical signals indicative of the position of a scanning beam of energy. The transducer 46 comprises a length of transparent material of high refractive index 48 having means 50 disposed in spaced relationship along the length, responsive to a scanning beam impinging thereon which causes the said means to transmit light along the length of material to an element 52 responsive to the transmitted light and converting it to an electric signal. The transducer may be utilized in an automatic system for scoring test papers or for reading ballots or the like in which a line of locations on the medium carrying the information is scanned with a beam of light to determine the locations at which the marks have been made. The system shown comprises a beam of light 10 from a source 12, which passes through an aperture 14 in a shield 16, and through a collimating lens 18 to an oscillating galvanometer mirror 20. After reflection by the mirror 20 the beam returns through the lens 18 striking a mirror 30. As the mirror 20 oscillates,the beam 40 reflected from mirror 30 scans a line of spaced locations 34 on a sheet of paper 32. If the beam strikes a location at which a mark has been made, less light is reflected, this being indicated by a photocell 36. A second beam 38 from the source 12 is reflected by a mirror 40 through a second aperture 42 in the shield 16 and passes through the lens 18 to the oscillating mirror 20 from which it is reflected back through the lens 18 to a mirror 44. The mirror 44 reflects the beam on to the transducer 46. At spaced locations along the length of a rod 48 of the transducer, corresponding to the spaced locations 34 on the paper 32, are mirror grooves 50 perpendicular to the axis of the rod, and when the scanning beam strikes one of these grooves the beam is scattered and transmitted along the rod energizing a photosensitive device such as a photomultiplier 52,to produce an output signal therefrom. As the beam scans the grooves 50 a train of pulses is sent out from the photomultiplier equal to the number of locations on the paper. Hence with marks on the paper being detected by the photocell the number and location of such marks may be indicated by a suitable counting device (not shown). The grooves 50 may be made responsive to a beam of electrons instead of light by filling them with a fluorescent material which produces light in response to an impinging beam of electrons.

[Also in Division H4] In a system for determining the physical properties of a gas, oscillations are maintained in a gas-filled resonant cavity having a neckshaped opening by means of acoustic feedback between an energizing transducer and a pickup transducer. As shown, a loudspeaker 5 (or Piezo-electric transducer), microphone 6 and amplifier 8 maintain oscillations in a hemispherical resonator 1 of volume V and having a neck 4 of length L and cross-sectional area S. The oscillation frequency f is given by (where k is constant, y is the specific heat ratio of the gas, R is the gas constant, T is the gas temperature and M is the molecular weight of the gas). For a given resonator geometry and a given gas, f provides a measure of gas temperature or the velocity C of sound in the gas (C equals the facor under the second square root sign) and can provide indirectly a measure of the current flowing through an electric heating element disposed in the resonator. In an embodiment for determining when the contamination of one gas by another (e.g. air by fire-damp) reaches a critical level, a band-pass filter 11 in the feedback circuit allows oscillations to be maintained only when that level is reached, and negative temperature coefficient resistances are provided in the filter circuit to make this determination independent of temperature. Alternatively the temperature independence is obtained by maintaining the ratio TS/VL constant by using a bi-metal strip (10) either to (a) operate a shutter (9), Fig. 2 (not shown) movable over the neck opening 4 to keep T.S. constant, (b) operate a bellows (9a Fig.3) coupled to the resonator to keep T/V constant, or (c) operate a tube (9b), Fig.4 (not shown) slidable in the neck opening 4 to keep T/L constant. To deaden vibrations of the resonator wall the wall may be made of rubber or of metal covered inside and outside with rubber. In a second embodiment Fig.7 for determining gas composition one resonator 19 is supplied with a reference gas and a second resonator 20 is supplied with a gas to be analysed. Both gases are piped through a thermally-insulated enclosure so that they are supplied at the same temperature. A signal proportional to the difference between the oscillation frequencies F 1 , F 2  of the two resonators is provided by a phase comparator 21. If this signal reaches a given level, corresponding to a given contamination of the gas in resonator 20, a gate 22 is opened to apply an audible frequency signal (e.g. from resonator 20) to an alarm 23 comprising an amplifier and loudspeaker. In a modification resonator 19 is replaced by an electrical oscillator whose frequency . is temperature dependent in the same way as the resonator frequency. Modifications of the transducer positioning in relation to the resonant cavity 1 are described.

In a transposed slot-conductor, the rate of transposition in end portions 7, 7 of the conductor, is double that in the central part 8, and the net shift of each conductor, although it has undergone complete transposition, is less than the number of conductors in one of the conductor stacks and such as to occupy asymmetrically disposed positions at opposite ends of the slot. If K is the ratio of the net strand-position shift to the total number of strands (K = 3/12 in Fig. 1 because, e.g., conductor a moves three positions from A to B), and L is the overall slot length, then the lengths of the end sections is ¢ LK (= <SP>1</SP>/ 8 L, as shown) and the length of the central portion is L(1-K), (=¥ L, as shown).
