Patent GB-979850-A (GB)
Title: Improvements in methods and apparatus for measuring the relative amount of a given component of a mixture of substances by selective absorption of infrared radiation
IPC: G01N21/3504
Filed: 1961-05-26
Abstract: 979, 850. Infra-red gas &c. analysers. OFFICE NATIONAL D'ETUDES ET DE RECHERCHES AEROSPATIALES. May 26, 1961 [June 3, 1960], No. 19152/61. Heading G1A. In an infra-red analyser radiation from a source 1, Fig. 1, is passed through two chambers 2, 3, the first containing the fluid (which may be in motion) whose concentration is to be determined from the extent to which it absorbs radiation, and the second containing a reference fluid, and the emergent radiation from the two is directed alternately by a rotating shutter 6 on to a detector 7 comprising two radiation sensitive elements so that the concentration may be indicated at 14 in terms of the difference between, or ratio of, the alternating signal from the two elements. In a first embodiment the elements are leadsulphide photo-electric cells 10, 12, in front of which are disposed interference type filters 9, 11, respectively. The filter 9 has a passband including wavelengths lying within the absorption spectrum of the test fluid, whilst the filter 11 has a passband which differs from that of filter 9 although it may embrace it. A semi-transparent mirror 8 8 transmits some of the radiation incident upon the detector to the photo-cell 11 and transmits the remainder to the photo-cell 10, the characteristics of the mirror and filters being such that the intensities of illumination of the two photocells is approximately equal when there is no selective absorbtion in either of the chambers 2 and 3. This arrangement is stated to result in there being an indication of absorption on the instrument 14 due to an alternating differential output from the photo-cells only when energy is absorbed in the chamber 2 within the passband of the filter 9, so obviating errors due to variations affecting both chambers. In another embodiment detector of the type disclosed in Specification 849,831 is utilized in which two successive layers of gas 15, 16, Fig. 3, are exposed to the radiation and the differential pressure produced is measured by a diaphragm capacitor 17. The gas 15 absorbs radiation within the absorption spectrum of the substance to be investigated and the gas 16 exhibits absorption outside this range. In either embodiment two sources may be used, each irradiating one of two separate chambers.

Title: Improvements in and relating to circuit arrangements for deriving a unidirectional voltage from a discontinuous a.c. voltage
IPC: H02P7/26
Filed: 1955-07-01
Abstract: 776,500. Rectifying; automatic speed control systems. GENERAL ELECTRIC CO. July 1, 1955 [July 2, 1954], No. 19156/55. Classes 38 (2) and 38 (4). [Also in Group XXXVII] D.C. motor M is driven from A.C. supply 16, 17 through diodes 14, 15 and thyratrons 12, 13 whose grids are energized with an A.C. component from transformer 18 through a phase shifting bridge comprising capacitor 20 and resistor 19, and a D.C. component from a capacitor 28 across which is connected potentiometer 24, resistor 25, potentiometer 26 and resistor 27 in series with the motor armature. Motor speed control potentiometer 24 is connected across capacitor 30 which is charged through rectifier 31 and transformer 29 from the A.C. supply. To prevent current through thyratrons 12, 13 from exceeding a safe limit, when this limit is reached the voltage across resistor 27 and potentiometer 26 is arranged to rise to a value which reduces the thyratron grid voltage. A signal voltage is derived from the thyratron current through current transformers 32 having a primary winding 32a, 32b in each thyratron anode circuit coupled respectively with the two halves of the centre-tapped secondary winding 32c. The output voltage of the two halves are rectified by a double diode 37 and the direct signal voltage thereby derived is applied across potentiometer 26 and compared through resistors 40, 40a with a reference voltage derived from capacitor 30 of a value determined by the setting of potentiometer 39. A voltage determined by the difference between the signal and reference voltages is applied to grid 49c of valve 49, the anode/cathode circuit of which is supplied from transformer 50 and rectifier 52, and which conducts to pass a current through resistor 27 and potentiometer 26. So that the signal voltage may be sufficiently smoothed, energy storing circuits each comprising a resistor 33 and a capacitor 34 are connected across each half of transformer secondary winding 32 and a capacitor 41 is connected between the grid and cathode of valve 49.

Title: Improvements in and relating to automatic storage devices
IPC: G06K17/00
Filed: 1962-05-18
Abstract: 1,010,162. Selective retrieval storage systems. EASTMAN KODAK CO. May 18, 1962 [May 31, 1961], No. 19179/62. Heading B8E. [Also in Division B6] The storage receptacles 40, Fig. 1, of a circulatory storage system are disposed on the periphery of a rotating drum 10 and in operation are continuously moved past a detecting station 19, Fig. 2 (comprising means for detecting empty receptacles) and a loading station 12A. The system is such that when an article is placed at the loading station it is subsequently automatically loaded into the first empty pocket to pass the detecting station after the article was placed at the loading station. The system is designed for the temporary storage of packets containing photographic film awaiting processing or despatch to the owner. Such packages are stored by placing them in a holder 117, Figs. 1 and 3, at the loading station where its presence is detected by a photo-electric device (not shown). This produces a signal whereby circuitry (not shown) associated with the detecting station is conditioned to provide an indication of the next empty receptacle to pass that station. The detecting station comprises a plurality of photo-electric detectors 64, Fig. 7, mounted one above the other so that each receives light from a lamp 66 when a receptacle 40 passing between them is empty. The receptacles are arranged (see Fig. 3) in vertically aligned rows so that the detecting station will simultaneously sense all the empty receptacles in a given vertical row. The circuitry is such, however, that only the empty receptacle nearest to the level at which the holder 117 is normally positioned (i.e. the position of Fig. 1) is signalled as empty. This signal is then used to control the operation of the loading station so that the package will be placed in the signalled receptacle. A punched card, on which identifying information will have been recorded when the package was placed in holder 117, also receives the empty cell identifying signal and records the location assigned to the package. A checking device is subsequently brought into operation when the package is loaded into its receptacle. This device causes the display of the actual location of the package if this differs from the one signalled. Such erroneous placing is then recorded manually. The retrieval of stored packages is automatically controlled by a punched card on which are impressed the locations of each of a group of packages which are to go to a particular destination. This card is read by means which control the sequential tipping of the appropriate receptacles 40 about their pivots 42, Fig. 7, as they pass discharge shoot 17, Fig. 1.

Filed: 1972-09-06
Abstract: 1361288 Automatic control of tension HONEYWELL Ltd 6 Sept 1972 [7 June 1971] 19241/71 Heading G3R To prevent oscillation in a tape spool motor drive the spool motor 3 is controlled by a circuit which receives signals representative of tape speed from a capstan motor 9 which is permanently energized in a direction tending to unwind tape from the spool. This energization is from a constant current source 10 so that the voltage across the motor represents speed. The tape (magnetic, perforated or cinÚ film) is drawn past a reading head 20 by a second capstan 7 driven by a stepping motor 6 controlled by external signals. A loop 2 is formed as shown and the bottom of this more or less intercepts a light beam illuminating a photo-cell 24, whose output is thus proportional to the size of the loop. The loop signal, the tape speed signal from motor 9, and a second tape speed signal from head 20 which also detects sprocket holes are combined in an amplifier 8 in an unspecified way to control spool motor 3. If the signal from motor 9 exceeds upper or lower limits an unspecified "safety mechanism" may be operated. The system may be duplicated as shown for the second spool 1'. Both work for wind and rewind.
