Title: Scanning Interferometer Using Wedge for Producing Fringes
Inventor: BARRINGER ANTHONY RENE
IPC: G01J3/453
Filed: 1967-01-10
Abstract: 1, 195,840. Photo-electric interferometers. BARRINGER RESEARCH Ltd. Jan. 9, 1967 [Jan. 10, 1967], No.1231/67. Heading G1A. An interferometer comprises a wedge producing Fizeau fringes which are imaged on a mask having a plurality of light and dark lines corresponding to the fringes produced by light of a predetermined spectral content and being movable cyclically relative to the fringes. Light passing through the mask 16, Fig. 2, is detected by a photo-multiplier 18 and a signal at the frequency of the mask movement or a harmonic thereof is detected by a synchronous detector 21 and indicates on meter 25 or display means 26 the presence of light of the predetermined spectral content. The mask may have sharp lines for detecting specific wavelengths or a complex pattern produced by photographing a spectrum e.g. of SO 2  or NO 2  gas, for detecting that spectrum in incoming radiation. The D.C. level at the output of amplifier 20 is kept constant by an AGC circuit 27. Light reflected from the wedge may be used to form the fringes and the relative movement of the mask and fringes may be effected by an oscillating parallel sided glass block, Fig. 4 (not shown). The spacing of the fringes may be made equal to the lines on the mask by adjustment of a zoomar lens between the wedge and the mask, Fig. 5 (not shown). In a modification Fig. 3, the angle # between the wedge 28 and mask 29 is varied cyclically so as to vary the effective spacing of the lines on the mask. As the spacing correlates with the fringe spacing for each spectral component of the incoming light 31 the signal from detector peaks and this output is recorded at 38 together with wavelength marker pulses synchronized with the variation of #. Undispersed light is received by detector 35 and used to vary the gain of amplifier 33 to compensate for variations in input light intensity.

Title: Improvements relating to the softening of water
IPC: C02F1/52
Filed: 1942-02-04
Abstract: 555,335. Purifying water. PERMUTIT CO., Ltd., AKEROYD, E. I., and HOLMES, E. L. Feb. 4, 1942, No, 1482. [Class 46] In the removal of salts from water, particularly in lime or lime-soda softening by crystallisation on to nuclei maintained in suspension within a reaction vessel through which the water with an added reagent is caused to flow upwardly, the water is so introduced that it flows uninterruptedly upwards through a vertical parallelsided reaction vessel 1 at a substantially uniform rate throughout the suspended bed and the speed of flow is correlated with the total quantity, size and concentration of the nuclei to ensure that the desired reactions are complete and all, or substantially all, the crystallisation has taken place when the water leaves the tap of the bed. The shape of the bottom of the vessel and the water inlet are correlated so that, at starting, the bed of nuclei is carried into suspension by the incoming water. The water may be introduced by a central pipe 3 and the reagent by a branch pipe 4 into a conical or pyramidal bottom 2 of comparatively small base angle. With a somewhat wider base angle, the reagent may enter by a pipe 7 and water by a pipe 5 having a conical outlet 6. With a still wider base angle, or a rounded bottom, the water may be supplied through a distributor 8. The reagent may be supplied through a branch pipe 11 adjacent the outlet of the water pipe 10. In lime softening with nuclei of 16 - - 32 mesh size and .6 mm. average diameter, the concentration of the bed should be above 30 per cent and may be as high as 80 per cent and the speed of flow between 2 and 4 feet per minute. As the nuclei grow, the speed may be increased to maintain the bed in suspension or it may be maintained constant and deposited nuclei removed. The treatment may be carried on at elevated temperature and pressure. Specifications 507,750 and 522,430 are referred to.

Filed: 1959-01-16
Abstract: 881,288. Digital electric calculating circuits. INTERNATIONAL COMPUTERS & TABULATORS Ltd. Jan. 27, 1960 [Jan. 16, 1959], No. 1656/59. Class 106 (1). An adder for summing two numbers each represented by a serial train of pulses occurring in separate groups, each group representing a digit of the number, comprises an adding element providing an output pulse train representing the sum of two input numbers, and means for applying the sum output pulse train, after a delay, to one input of the adding element, and for concurrently applying to the other input of the adding element a pulse train representing a filler digit when the addition of a filler digit is required. Numbers to be added may be stored in tracks 24a, 11 on a magnetic drum store of the type described in Specification 851,742. Each digit of the numbers is, for example, represented by a serial combination of pulses representing values 1, 2, 4, 8. The two numbers to be added are re-timed so as to be synchronized with one of five clock pulse trains derived from tracks 20a-20e. The re-timing circuit for track 11 comprises AND gate 27 and flip-flop 28, and a similar circuit 32 is provided for track 24a. The setting of flip-flop 34 determines whether the numbers will be added or subtracted. In adding, pulses from track 11 are supplied to one input of element 26 through gates 31, 37, and pulses from track 24a are supplied to the other input of element 26. The sum output of element 26 is supplied over line 48 to a comparison circuit 45 which has as its other input the inverse of a filler digit obtained from track 12. For decimal numbers, the filler digit is 0110 (6) and the inverse of this is 1001 (9). Other filler digits, for example, for pence, shillings and pounds or for tons, hundredweights and quarters may be recorded on track 12 and selected by choice of clock pulse track. Circuit 45 provides an output if the sum output on line 48 is greater than the inverse of the filler digit. OR gate 49 receives the output of circuit 45 and also the carry output of element 26. Thus if the sum output is greater than or equal to the scale of the digit, flip-flop 44 is switched on and opens gate 56 whereby, in the period immediately following the input digit pair, the filler digit is applied to one input of element 26 through gates 40, 56, 37, and concurrently, the sum output of element 26, after passing through delay device 54, e.g. an ultrasonic delay line or a shift register, is applied to the other input of element 26. The corrected sum output is then obtained on line 57 through gate 58. Subtraction is performed by complementary addition; the digit from track 11 being added to the filler digit in complementor 38 and then inverted so that the complement of the input digit is applied to element 26 through gate 37. Specifications 678,427, 738,314 and 738,605 also are referred to.

Abstract: 900,240. Mono-stable state circuits. ERICSSON TELEPHONES Ltd. Jan. 14, 1960 [Jan. 17, 1959], No. 1788/59. Class 40 (6). A blocking oscillator comprises an amplifier with regenerative transformer coupling, the amplifier being arranged to drive the transformer core into saturation. A transistor 1 is arranged in a common base circuit with a transformer 4, which may be toroidally-wound coupled between collector and emitter. Alternatively the transformer may be connected between collector and base, or emitter and base. The circuit is normally cut off in a quiescent state, and is switched to its unstable state by applying positive-going pulses from a source 5 to the collector. The circuit parameters are made such that the collector current causes the transformer core to saturate giving an I c /time curve as shown in Fig. 4. The time period then varies by only a small amount t s , t 6  for large variations in circuit parameters, e.g. #<SP>1</SP>=n to #<SP>1</SP>=5n. The load resistor 8 is connected to the emitter by a diode 9, and a further diode 10 is connected to clamp the collector to - 50 v. to limit overshoot at the end of the output pulse. A number of transistors may be used instead of a single transistor.
