Title: Method of and apparatus for range finding
IPC: G01S17/08
Filed: 1976-04-01
Abstract: For the purpose of distance measurement, use is made of an optical correlator which has at least one imaging system (11, 15), at least one optically active grid structure (10) and a photoelectric receiver system (20-27) assigned to said structure. A principal maximum in the output signal of the photoelectric receiver system characterises the geometrical image position. For the purpose of uniquely determining this maximum as against other possible maxima, different beam paths are produced in the image space and/or Fourier space, and photoelectric receiver systems are assigned to them. In the case of an axial relative movement of an object image with respect to the grid structure, there is produced at each of these photoelectric receiver systems an output signal which always differs from that obtained from another beam path in terms of its frequency and differs in its phase angle in the ratio of the two signal frequencies, both signals having the same phase angles for the principal maximum. The geometrical image position of the principal maximum with respect to the geometric image positions of other possible maxima is determined by comparing these phase angles. <IMAGE>

Title: Improvements in electromagnetic interrupters
IPC: H04M19/02
Filed: 1941-10-15
Abstract: 552,651. Automatic exchange systems. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., and FRYDMAN, E. Oct. 15, 1941, No. 13264. [Class 40 (iv)] [Also in Group XXXVII] Alternating current for ringing and tone signalling is derived from a direct current supply by means of a vibratory relay the periodicity of which is determined by a condenser of large capacity. As shown, the relay RV, which is slugged to retard its operation and release, is maintained after its contact rvl opens over both windings in series until the condenser Cl is fully charged. When the contact recloses, the operation of the relay is delayed by the discharge of the condenser through its lower winding. The condenser may have a capacity of the order of 2 mf. The relay may have a single winding only, the condenser C1 and resistance R1 being shunted across the contact rvl. At contact rv2, the relay energizes alternately the opposite halves of the centre-tapped primary of a transformer TR in series with a choke I. Resistances R2, R3 and condensers C2, C3 serve for spark-quenching and smoothing.

Class 103 (v) [Also in Group XXII] A central buffer, comprising a buffer plate extending over a considerable portion of the width of the end wall of the vehicle, is characterised by the feature that the buffer plate comprises a die forging having integral lateral connecting flanges or arms which are fixed to supporting members therefor on the vehicle body, and is provided in the middle at the bottom with an integral hook member which is open to the rear for the reception of a coupling. In the embodiment shown a one-piece buffer plate 3 has two lateral backwardly extending flanges 4 which are butt-welded to the supporting members 2 of the truck body 1. The coupling hook 5 is formed integrally with the plate 3 and has its open end closed by a welded on plate 6. Strengthening ribs 7, 8 are provided. In a modification (not shown) the ribs 7, 8 are replaced by a plate 3. Instead of being butt-welded, the flanges 4 may be riveted to the members 2 and seam welded in order that the buffer may more readily be removed from the truck.

Title: Improvements relating to the production of insoluble azo dyestuffs on textile fibres
IPC: D06P3/68
Filed: 1935-05-04
Abstract: Azo dyes, forming upon the material; printing; stable diazo compounds.--Insoluble azo dyestuffs are produced on textile fibres by application to the fibres of a mixture containing a condensation product of a mono-, di- or trialkylolamine with a diazonium salt of an arylamine base free from sulphonic groups, a coupling component likewise free from sulphonic groups, and an alkali, followed by the subjection of the fibres to treatment with an acid, e.g. by an acid steaming operation or by passage through an acid liquor.  For printing, the mixture is made into a paste with a thickening agent. The stable diazo compounds employed may be prepared by diazotizing the arylamine, neutralizing the solution, mixing with the alkylolamine and filtering off the product which separates out.  In examples: (1) dianisidine is tetrazotized and condensed with triethanolamine, the product is mixed with starch tragacanth thickening, 2 : 3-hydroxynaphthoic acid, caustic soda and turkey red oil, the mixture is printed on cotton and a navy blue print is developed by steaming in steam made acid with the vapour of acetic or formic acid or both; (2) a red print is similarly obtained by using the condensation product of diazotized 5-chloro-2-aminotoluene with diethanolamine as diazo component, and 2 : 3-hydroxynaphthoic acid anilide as coupling component.

Abstract: 217,230. Huth Ges., Dr. E. F. June 5, 1923, [Convention date]. Thermionic value circuits.-A sudden drop of a discontinuous character is effected in the internal resistance of an electric discharge device, operating by gas ionization or by thermionic or electric discharge, which drop remains stationary by first applying a high voltage to the auxiliary electrode and then removing it. The voltage is positive with respect to the cathode and may be applied by bridging over a portion of the discharge path by a resistance, capacity or inductance or by a combination thereof. Fig. 6 shows a thermionic tube having a condenser c and resistance r bridging the anode a and grid g arranged to generate oscillations in a circuit C, L. R. The variation of the internal resistance R is shovn in Fig. 5 relatively to the anode voltage Va, the dotted curve showing normal operation while the full curve shows the effect of the break-down of the resistance due to the application of the voltage to the auxiliary electrode. In modifications the variation of the internal resistance is obtained by applying temporarily a voltage between the grid and cathode, or a voltage between the grid and anode, or in a four electrode valve by applying one voltage between the anode and one grid and a second voltage between the cathode and the second grid, or bv magnetic control for at least a portion of the discharge path.
