Abstract: 1,013,740. Photo-electric apparatus. PYE Ltd. July 3, 1964 [July 4, 1963], No. 26471/63. Heading G1A. In optical apparatus e.g. a spectrophotometer, the detector is adapted to receive two light beams, one after transmission of light from a source through either a sample or a reference body and the other from the same source or a similar or other source, and there are provided means to interupt periodically at least one beam, and means in the detector circuit, to indicate the ratio of intensities received when the sample or the reference body is in the light path. The detector used is a photomultiplier and the apparatus is designed to enable fast measurement to avoid the effect of gradual changes in the sensitivity of the photomultiplier over a long period. In one arrangement (Fig. 2), a chopper C-alternately interrupts the beams A and B to give a series of square folds in the detector D and meter M. with the reference body R in the light path, the aperture T is adjusted to make the height of the voltage pulses a 2  received by the meter for the beam A, equal to those D received for the beam B. The sample S is then moved into the light path and gives pulses of height a 3  which value is compared in the meter system M with the reference a 2  (=b) to give an indication of the transmissivity of the sample. In other arrangements the chopper may interrupt only one beam, in which case suitable arrangements in the meter are provided to allow for this. The variable aperture may be in both beams, and the same source L 1  may be used to provide both beams. The light used may be monochromatic.

Title: Transportation system
IPC: B61B15/00
Filed: 1974-06-15
Abstract: 1476783 Transport systems; automatic train control P M BOURASSA 15 June 1974 26614/74 Headings B7L and B7N A transportation system comprises a continuous main traffic line 2 between two points of which extends a station traffic line 5 having oppositely inclined end sections 6 extending upwardly from said points a predetermined height to a station 4; car units 1 each having a relatively high cruising speed motor 12 to drive the unit only when in the main line 2 and a relatively low speed motor (14) activated on the upward incline 6 to drive the unit along the station line 5 at a predetermined low speed but provided with an overrunning clutch (15) so that the low speed can be exceeded on the inclines 6. Gravity effects acceleration and deceleration of the unit between the low speed and cruising speed during travel along the inclines. The system includes several such stations and each car unit 1 is equipped with a station selection circuit, Fig. 9, in which selected switches 49a- 49e are closed to energize sliding contacts 50 and 51a-51e which project from the unit to engage corresponding contacts 61 and one of 62a-62e which are provided prior to each station and divert the unit into a station line if required. Circuitry for automatic opening and closing of doors on the unit and on the station platform is also provided, Fig. 15 (not shown). Spacing of the units 1 is controlled as shown in Fig. 16 by a series of conductor sections 136 extending along the main line adjacent to a series of rail sections 134 on which wheels 9 of the units run, each conductor section 136 being co-extensive with a rail section 134 but connected by conductors 137 to the preceding rail section 134. Power supply means 135 energize each pair of sections 134 but are short-circuited by the wheels 9 and axle 11 of a car unit in that section of track. However, when the unit vacates the track section, the conductor sections 136 are energized from the rail sections 134 via the conductors 137 so that contacts 85 and 86 projecting from a following unit in the next track section receive supply to energize a coil 89. This causes opening of a switch 90 to de-energize braking system 93 and actuate motor 12 of this following unit which then proceeds into subsequent track sections. In each station traffic line, the track sections become progressively shorter as the unit approaches a stopping zone, and there is interaction with the spacing control means of the main line sections by-passing the station so that a unit can only leave the station line when a suitable gap in the main line exists.

Abstract: 1,184,791. Electrolytic cells. MARSTON EXCELSIOR Ltd. May 31, 1967 [June 15, 1966], No. 26638/66. Heading C7B. Salt solutions are acidified in an electrolytic cell by introducing separate streams of the solution into a catholyte chamber 16 containing a cathode 12 and into an anolyte chamber 17 containing a hydrogen-permeable anode 13 e. g. via inlets 26 and 27, passing D. C. between the cathode and anode to promote ion exchange through an ion-permeable diaphragm 18 between the chambers, supplying hydrogen gas e. g. via inlet 22 and space 23 to the anode interior to be oxadized to hydrogen ions, and removing the resulting acidified salt solution and alkaline salt solution respectively from the chambers 17 and 16 e. g. via outlets 29 and 28. The hydrogen gas is preferably supplied from that liberated at the cathode. The ion-permeable diaphragm may be of glass cloth or asbestos fibre. The cathode may be of graphite, Ti, Ti-clad steel or Cu, stainless steel, Ni or Pt, or a Ta screen holding a dispersion of PTFE with Pt black alone or on carbon; the anode may be of porous Rh, Pd, Ir or Pt, alone or as coating on Ti, Ta or Nb, or porous Ni or graphite. A stack of cells may be used wherein the anolyte and catholyte chambers of each pair of adjacent cells are separated by a bi-polar electrode through which hydrogen liberated at the cathodic face can diffuse to the anodic face. The invention is applicable to the acidification of brines e. g. seawater, and other alkali or alkaline earth metal salts such as sodium sulphate, nitrate or phosphates, particularly used in the production of hypochlorite.

Abstract: 1,023,681. Sintering machines. RICHARD THOMAS & BALDWINS Ltd. July 25, 1962 [July 25, 1961], No. 26902/61. Heading F4B. Material is sintered in the form of a bed on a moving sinter strand and is fed at a rate corresponding to the volume of air drawn through the bed (i.e. the difference between the volume of air flowing through and the leakage air entering the suction system). Suction is set up by the fan 6 beneath the bed of raw material on the sinter strand 1, in the suction heads 3 and in the main 5, discharge being through a duct 7 leading to a chimney. Through a tapping 8 in the main 5 the pressure is applied to a flowmeter 9 which includes an adjustment device 10 so that a signal in accordance with the expression " Leakage volume = Leakage factor #strand suction " is fed to the computing unit 11. A Venturi 12 is connected to a flowmeter 13 so that a signal corresponding to the flowrate through the fan is fed to the unit 11 where it is corrected for temperature by a signal from the instrument 15 connected to the thermocouple 14. A unit 16 feeds to the unit 11 a signal corresponding to the volume of air required per ton of raw material although the computing unit may alternatively be set to take account of this factor. The resultant signal from the computing unit is fed into an instrument 17 which also receives a measured feed rate signal from a tachogenerator 18 driven by the belt 2 for conveying raw material to the strand. A discrepency between these signals constitutes an error signal which, after amplification is used to modulate the speed of the electric motor that drives the belt 2.
