Title: Method for measuring the speed of motion of road vehicle
IPC: G01P7/00
Filed: 1971-04-19
Abstract: 1293782 Measuring speed ITT INDUSTRIES Inc 19 April 1971 [26 Jan 1970] 20168/71 Headings G1K G1N The instantaneous speed V of a road vehicle is measured for a limited period of time by storing a measurement of the speed at the beginning of the period derived from the rpm of one wheel and adding thereto the speed as derived from integration of subsequently measured rate of speed variation corrected for the angle of inclination of the road to the horizontal, the rate of speed variation being derived from the relative displacement of a mass m supported on the vehicle so as to be capable of moving relative thereto in the direction of the longitudinal axis of the vehicle against an elastic restraint, which mass m is normally maintained in a fixed position and is only released therefrom for the time of the measurement. The measurement may be carried out during each individual braking process of the vehicle by arranging for it to be initiated by the application of the brake, but prior to its response. The inclination of the road may be sensed by a pendulum swinging in the median plane of the vehicle, the pendulum being retained in its position at the beginning of each measurement. Deviations of the angle may be measured by means of a non-damped astatic pendulum. The initial angle is stored and continuously corrected for deviations therefrom. The sine of the angle is integrated with respect to time and, after multiplication by the gravitational acceleration g is subtracted from the measured value of travelling speed.

[Class 40 (iii)] A symmetrical filter through which audiofrequency signalling current is transmitted to power mains, is connected in tandem with one having the same matrix with the algebraic signs of the elements in one diagonal reversed. The input impedance is then always equal to the output load at the mid-band frequency. Variation in the impedance presented to the filter output by the mains is thus prevented from giving rise to reactance in the sending- end impedance of the filter at that frequency, and the same condition may hold approximately over a limited band of frequencies. If the input current and voltage i1, v1 of the primary filter are related to the output current and voltage i2, v2 by the equations where A, B, C are parameters of the filter, then the compensating reaction is so designed that its input current and voltage io, vo shall be related to its output current and voltage i1, v1, either by the equations or by the equations The Specification shows how to apply the principle to a simple low-pass filter section.
Patent GB-796909-A (GB)
Title: Purification of organic acids
Inventor: MACLEAN DUNCAN
IPC: C07C51/487
Filed: 1956-07-04
Abstract: Phthalic, terephthalic, isophthalic or benzoic acid or mixtures of any of these acids containing metallic impurities are purified by dissolving the acid in an excess of aqueous alkali, adding a metal sequestering agent and separating the carboxylic acid salts from the solution.  The acids are regenerated from their salts by acidifying with a mineral acid such as hydrochloric or sulphuric acid.  The sequestering agent specified is ethylene-diamine-tetra-acetic acid which is used in the form of its disodium salt.  The metallic impurities may be cobalt, nickel, manganese, titanium or barium and these are precipitated as hydroxides when the impure acids are dissolved in the alkali which is usually sodium hydroxide solution. These hydroxides are filtered off before the sequestering agent is added.  This complexes with any residual metal ions and the solution is then concentrated by boiling under reduced pressure when the aromatic acid salts crystallize out.  The crystals may be washed with a chloride solution, e.g. sodium chloride.  Potassium hydroxide may be used as solvent for the crude acids when they are to be converted to terephthalic acid by another process.  In Examples (i), (ii) terephthalic acid containing manganese, titanium, nickel and iron is treated with sodium hydroxide at pH 8-9, the filtered solution is then treated with 3 and 10 per cent of disodium ethylene-diaminetetra-acetate; (iii) as (i) but using a mixture of benzoic and isomeric phthalic acids, (iv) as (i) but with barium as an additional impurity.  Optical density measurements in ammoniacal solution are given.

Abstract: 573,356. Photographic cameras. KODAK, Ltd. Dec. 10, 1943, No. 20716. Convention date, Dec. 10, 1942. [Classes 97 (i) and 98 (i)] An astronomical camera, includes a secondary optical system which projects an image of a fiducial mark on to the sensitive surface to indicate accurately the position of the true zenith. The camera comprises a long-focus objective 10, a multiple blade shutter 15, mirrors 11, 12 and a light-sensitive surface 14 accommodated in a housing 19. The secondary system comprises a clear glass plate 21 inclined to the axis of the camera, a collimator 22, mirrors 23, 24, a reticle 25 containing a fiducial mark, and a Gauss eyepiece 26 for illuminating and viewing the reticle. The latter is mounted at the rear of a pivoted tube 33 and is adjustable by screws 37 engaging a bearing ring 36 on the tube. The fiducial mark consists of opaque cross-hairs on a transparent or translucent reticle. A level reflecting member 27 is pivoted on a stud 29 so that it can be swung into or out of the optical path, and may comprise a pool of mercury in a cup 28 sealed by a glass plate 30. In operation, the collimator axis is set exactly perpendicular to the mercury surface by viewing and adjusting the reflected image of the fiducial mark, and thereafter the mercury pool is swung away and the shutter opened to make simultaneous exposure of the stars and the fiducial mark. The reticle is made small so that the recorded mark will obscure but little of the image surface. An alternative to the mercury pool is a mirror floating in a shallow depth of a suitable liquid, e.g. mercury. Excessive movement of the mirror away from the central position. is prevented by a small pin.
