Patent GB-666270-A (GB)
Title: Improvements in or relating to optical systems applicable to spectrometers
IPC: G01J3/08
Filed: 1949-03-22
Abstract: 666,270. Utilizing light. PARSONS & CO., Ltd., C. A., and BACKHOUSE, L. S. March 7, 1950 [March 22, 1949], No. 7796/49. Class 40 (iii). [Also in Group XX] An optical system in which radiation from a source traverses a sample and further radiation from the source travels along a different path containing a blank, the two beams thereafter alternately traversing a spectrometer slit, comprises a pair of reflectors inclined to each other and means for reciprocating said reflectors in a vertical plane so that each reflector in turn selects radiation from one or the other of the two paths and directs the radiation on to said slit. As shown, radiation from a source r, e.g. a Nernst filament, is directed by plane mirrors m<SP>1</SP>, m<SP>2</SP> on to concave mirrors m<SP>3</SP>, m<SP>4</SP>, whereby it is directed on to concave mirrors m<SP>5</SP>, m<SP>6</SP>. Radiation from the mirrors m<SP>5</SP>, m<SP>6</SP> is alternately directed on to the slit S of a spectrometer by relatively inclined mirrors m<SP>7</SP>, m<SP>8</SP> which are reciprocated vertically as by a crank and disc arrangement. A sample is placed in one of the paths of the radiation and a blank in the other path so that the intensity of the radiation falling on a thermo-couple, bolometer or other detector in the spectrometer fluctuates and an A.C. component is contained in the output from the detector. This A.C. component may be amplified and used to control a variable aperture in the path containing the blank. This aperture is varied until equality between the two beams is attained, the aperture opening then giving a direct measure of the percentage transmission of the sample.

Title: Determination of Ocean Sound Velocity Profiles.
IPC: G01H5/00
Filed: 1968-02-19
Abstract: 1,194,282. Measuring sound velocity. SINGER-GENERAL PRECISION Inc. 19 Feb., 1968 [22 May, 1967], No. 7939/68. Heading H4D. A profile of sound velocity as a function of distance in the sea is obtained from the echo times of pulses transmitted in a narrow beam and scattered from impedance discontinuities in the sea. In the Fig. 1 embodiment for determining sound velocity distribution with depth a pulse from directional transmitter transducer 12 is scattered at 17 (e.g. by marine life, gas, temperature or salinity discontinuity) and received by hydrophones 14, 16 with a phase difference or travel time difference #t related to the depression angle of scatterer 17. Hydrophone 14 output is applied via detector 18 (an envelope detector or sine-zero crossing detector) to a tapped delay line 20 whose taps feed first inputs of AND gates 24. Hydrophone 16 output, via a similar detector 22, feeds second inputs of the gates, whereby the particular gate which produces an output signal represents a particular depression angle of scatterer 17. Count generator 28 is started on transmission of the sound pulse and feeds clock pulses to first inputs of further AND gates 26 having the outputs of gates 24 as their second inputs. When a particular gate 24 produces an output signal a corresponding gate 26 gates a clock pulse to sequential register 32 which thus provides an indication of the depression angle. The total time counted by generator 28 gives the pulse echo time. Values of depression angle and echo time for different scatterers are applied to computer 34 for statistical analysis and conversion to a velocity profile which can be displayed or used in sonar ranging. Relative and absolute phase delays of signals received by hydrophones 14, 16 may be measured instead of time intervals. Transducer 12 may be used as an additional hydrophone. In the Fig. 2 embodiment a hydrophone array 54 and beam former 58 define a plurality of fixed reception lobes 56 which intersect the sound pulse transmission path. The echo signals are selected by threshold circuit 64, which discriminates against background noise, and open gate 68 to apply the total count of a clocking device 70 (which is started on transmission of the sound pulse) to a velocity-evaluating computer which also receives depression angle data from beam former 58. Instead of several fixed reception lobes 56, a single steerable lobe may be provided by suitably phasing hydrophones 54. In either embodiment the equipment may be mounted on a ship or on floating buoys, or anchored to the sea bed. Data may be transmited by radio telemetry and distances between the buoys may be determined by radar or optically.

Filed: 1940-05-08
Abstract: 543,737. Ammunition projectiles. DUYNSTEE, A. W. T. J., and POSSEN, L. H. May 8, 1940, No. 8313. [Class 9 (i)] A projectile is provided with a rear extension containing a chamber filled with a powder charge which is fired as a direct or indirect consequence of the explosion of the main charge in order to assist the propellant and even out the peak pressure within the gun barrel, the chamber being closed by a disc the rim of which has besides a cylindrical part, a conical or extended cylindrical part forming a gas-tight fit with a correspondingly shaped opening in the end wall of the chamber. In one form an extension 2 screwed on the rear end of the projectile, has a chamber 3 closed by a disc 4 having a gas-tight conical seating upon a flange 5. A cylindrical extension 13 on the disc 4 is guided by a ring 17 which acts as a guide for the extension 13 and an abutment for the disc 4 when blown outwards by the explosion of the charge in the chamber 3. A spring 18 normally keeps the disc 4 seated. The ring 17 is supported by three bars, of which one is shown at 15, extending from a ring 14 screwed beneath the flange 5. A casing 6 screwed into the disc 4 houses a detonator 8 held in position by a spring stirrup 9, the detonator moving by inertia against a firing pin 12 when the gun is fired. Alternatively the detonator may be fixed and the firing pin movable by gas pressure as the main charge is fired. In a modification a fixed firing pin and movable detonator are mounted on the base of the projectile, and in another form a fixed detonator on the base is struck by a movable pin mounted on the disc 4. The seating of the disc 4 may have a cylindrical extension above the cone, or a stepped cylindrical closure may be used. A tubular member extending beyond the ring 17 may be screwed to the extension 2 so that the cylindrical extension 13 of the disc 4 does not project when the disc 4 is blown outwards against the ring 17. The invention may be combined with an arrangement in which the gases escape through inclined bores to cause rotation about the longitudinal axis.
