Title: Improvements in the measurement of the transmission time of electrical oscillations
IPC: G01S13/08
Filed: 1927-08-13
Abstract: 283,538. Kunze, W. Aug. 13, 1927. [A Specification was laid open to inspection under Sect. 91 of the Acts, Jan. 14, 1928]. Ear-pieces and attachments.-The distance between two places or the transmission time of electric oscillations between them is determined by sending electric oscillations from a transmitter at one of the places to a receiving station at the other which controls a transmitter by which the oscillations are sent back to a receiver at the first station. A second receiver receives the oscillations directly from the transmitter and from the difference in time between the reception of the signals at the receivers the distance between the two stations may be determined. In order to determine the small interval of time between, the direct and indirect receptions, the binaural hearing method shown in Fig. 2 may be employed. Telephone earpieces 31, 32 are connected to the direct and indirect receiving sets 29, 30 and lead to the left and right ears of an observer by indiarubber tubes or pipes 33, 34 of variable length. The lengths of these tubes are adjusted by a slide until the source of sound appears to be in the medial plane, the difference of the times of reception being deduced from the difference in the lengths of the tubes.

Title: A method and preparation for imparting a durable form to human hair or other proteinaceous fibres
IPC: B05D7/20
Filed: 1953-08-04
Abstract: An ester of an amino-alcohol with titanic or zirconic acid, the amino-alcohol having the formula HORN(R1)(R11), where R is ethylene or an alkyl-substituted ethylene group, R1 is a b -hydroxyalkyl or b -aminoalkyl radical, and R11 is hydrogen, an alkyl radical of 1 to 3 carbon atoms or a b -amino-alkyl or b -hydroxy alkyl radical, is obtained by an ester exchange reaction between an alkyl titanate or zirconate and the amino alcohol, which may be triethanolamine, b -aminoethylethanolamine or diethanolamine.  The number of hydroxy groups per titanium or zirconium atom may vary from two to twelve, typical products being obtained by the reaction of one mol. of butyl titanate with one mol. of diethanolamine or two mols. of b -aminoethylethanolamine or four mols. of triethanolamine.  In examples, esters are produced from triethanolamine and tetrabutyl titanate or tetrabutyl zirconate, and from b -amine-ethylethanolamine and tetra-isopropyl titanate. In example (8), triethanolamine is reacted with tetrabutyl titanate at 25 DEG  C., and butyl alcohol is distilled off under reduced pressure to leave a triethanolamine solution containing 5 aminoalcoholic hydroxy groups for each titanium atom.ALSO:In a process of curling or crimping human hair, horse hair, wool, silk, zein, casein, soyabean, peanut or other protein fibres, or straightening already curly human hair, the fibres are treated with a liquid comprising an ester of titanic or zirconic acid with an amino alcohol of the formula HORN (R1) (R11), where R is ethylene or an alkyl-substituted ethylene group, R1 is a beta-hydroxyalkyl or betaaminoalkyl radical and R11 is hydrogen, an alkyl radical of 1 to 3 carbon atoms or a beta-aminoalkyl or beta-hydroxyalkyl radical. The ester may be obtained by an ester exchange reaction between an alkyl titanate or zirconate, such as tetra-butyl titanate or tetra-isopropyl titanate, and an amino alcohol such as triethanolamine, beta-aminoethyl-ethanolamine or diethanolamine. The ester may be a liquid suitable for application without dilution or may be applied in aqueous or alcoholic solution.  The treatment of human hair may be at room temperature or above and the solution may be activated by the inclusion of, or by pre- or after treating the hair with, acetic or formic acid, ammonium chloride, sodium hydroxide, sodium carbonate, ammonium carbonate, borax, ethylene diamine, hydrogen peroxide, sulphides or disulphides.  Human hair may be wound upon curlers, and the liquid may be applied by a sponge and removed with water after a period varying from 5 minutes to 3 hours while the hair is still wound or after unwinding the hair.  The hair may be after-treated with hydrogen peroxide and is subsequently dried.  In Example VIII wool cloth is impregnated with an aqueous solution of the ester obtained by reacting triethanolamine and tetrabutyl titanate at 25 DEG C., whereafter it is squeeze-dried, pleated and simultaneously dried on a roller heated to 140 DEG C., and finally washed with water and dried.

Abstract: 866,031. Protective cut-out arrangements. CHARBONNAGES DE FRANCE. July 7, 1958 [July 9, 1957; March 25, 1958; June 2, 1958], No. 21761/58. Class 38 (5). In a protective arrangement the occurrence of faults which may be of high resistance is detected by one or more relays which respond to an increase in the highfrequency current injected into the protected system by an electronic high-frequency generator through one or more series inductance - capacitance circuits presenting a low impedance to the high-frequency current, the power source and the apparatus supplied by the source being provided with parallel capacitors so as to form parallel inductance-capacitance circuits presenting a high impedance to the high-frequency current under normal conditions. The high-frequency generator may comprise a transistor oscillator 6, Fig. 1, and a coupling transformer 10 associated with a capacitor 9, a variable resistor 7 and a potentiometer 8 arranged to provide two high-frequency signals of suitable amplitudes with a phase displacement of 90 degrees between them. These signals are amplified in channels each comprising a transformer 15, push-pull power transistors 17, 18, a transformer 21 and push-pull power transistors 23, 24, the amplified signals being applied to the primary windings of transformers 27, 28 which have Scottconnected secondary windings to provide a balanced three-phase high-frequency current for injection into the protected three-phase power circuit through series connected inductors and capacitors 29 . . . 34. Various over-voltage protective devices are indicated as diodes 35, 36. Zener diodes 39, 40 and 41, 42, or as varistors 43, 44 associated with tertiary windings of the transformers 27, 28. Relays X1, X2 cause a warning to be given or the tripping of a circuit-breaker should either amplification channel fail. Fig. 1 also shows the capacitors 45 . . . 47 connected in parallel with the power supply source S. Fig. 2 shows one of a number of different arrangements described in which the relay or relays are associated with the highfrequency generator G and protect the system as a whole. In Fig. 2 the voltages produced across the series inductors 51 . . . 53 are rectified at 54 . . . 56 and applied to the operating coil of a common relay 57 which effects the opening of a circuit-breaker, contactor or main relay. Similarly, Fig. 6 shows an arrangement in which current transformers 71 . . . 73 associated with an individual circuit energize relays 74 . . . 76 through filters 81 and rectifiers 77 . . . 79. In Fig. 14 (not shown), the neutral of the supply source is connected through a capacitor to earth to enable protection to be obtained against earth faults. The Specification also describes single phase arrangements and refers to the use of electron tubes in the high-frequency generator.
