Title: Improvements in or relating to pressure-equalising devices for brakes and the like
IPC: B60T11/06
Filed: 1920-11-03
Abstract: 175,354. Shackleton, W., and Sheffield Simplex, Ltd. Nov. 3, 1920. Force-transmitting mechanism. Relates to pressure-equalizing mechanism, particularly for brakes, of the kind comprising a pair of coaxial shafts with pressure-applying members mounted to rotate therewith, and a single operating member screw-threaded for engagement with screw-threaded parts on the shafts, and consists in splining the pressure-applying members on the shafts so that thev do not partake of the axial movement of the shafts and also of an arrangement in which each of the shafts operates similarly another pair of coaxial shafts so that an equalized pressure is applied to four members. The operating-arm 4 is secured to the two-part sleeve 1, 2 having opposite handed screw-threads engaging respectively the correspondingly threaded ends of shafts 8, 9 mounted in bearings 16, 17 on the chassis members of a motorvehicle. The shafts 8, 9 are free to slide axially and are splined at 10, 11 to sleeves 12, 13 secured to the pressure-applying arms 14, 15 and having a bearing on the reduced ends of the sleeve 1, 2. Assuming that when the member 1, 2, 4 is operated, the shaft 8 and sleeve 12 are turned to cause the member 14 to meet its resistance first, further operation of the member 4 will then cause the shaft 8 to move axially without rotation and to press the pressure ring 7 upon the end of the shaft 9, whereby it is rotated until the pressures applied through the members 14, 15 are equal. The relative angles of the members 14, 15 may be adjusted, for example to compensate for wear, by turning the rod 19 so that its end 20 which screws into the shaft 8, is extended from the end of the shaft the necessary amount. The rod 19 is turned by a head 21, splined thereon at 200 and having teeth 24 which are normally kept in engagement with teeth on the shaft 8 by a spring 23 to lock the rod in adjusted position. In a modification the outer ends of a pair of shafts operated as are the shafts 8, 9 are splined each to a sleeve which has opposite-handed screwed engagement with two other tubular shafts each splined to a sleeve having an arm such as 14, 15. An equalized pressure is thus applied by a single member such as 4, to form other members.

Title: Seismic prospecting
IPC: G01V1/00
Filed: 1969-06-20
Abstract: 1278628 Seismic prospecting SOC NATIONALE DES PETROLES D'AQUITAINE 20 June 1969 [21 June 1968] 31263/69 Headnig H4D In a seismic reflection prospecting system in which reflection signals are cross-correlated with a representation of the transmitted signal to determine travel times, the amplitudes of secondary maxima of the correlation functions are kept small (to avoid confusion with weak main maxima) by making the transmitted signal a series of discrete acoustic impulses of substantially constant amplitude, the number of impulses in the series and the intervals of time separating them being so selected that the autocorrelation function of the transmitted signal has secondary maxima with amplitudes less than a given small fraction of its main maximum, and the representation is a time function with a value " 1 " at each instant when an impulse is transmitted and a substantially zero value during the intervening periods. For marine prospecting a seismic source (gasgun or sparker) and hydrophone streamer are towed by a ship. A signal comprising constant height pulses randomly spaced is played back from a magnetic tape and controls actuation of the source to produce a series of, e.g. 400 acoustic impulses over a period of 48 seconds. The interval between impulses may be 20 + 2x milliseconds, where x is selected randomly in the range 1 to 100. The control signal and received reflection signals are fed to a multichannel recorder for subsequent cross-correlation.

Title: An antibiotic picromycin and salts thereof
Filed: 1950-12-28
Abstract: An antibiotic, picromycin, is produced by cultivating on a suitable nutrient medium a picromycin-producing strain of Streptomyces felleus, a description of which is given, and isolating from the culture filtrate a substance having a melting point of 169 DEG  to 170 DEG  C., [a ]24D in chloroform (c=6.3 per cent) - 50.2 DEG , [a ]24D in alcohol (c=3.5 per cent)=8.2 DEG  nitrogen content of 3 per cent and no methoxyl.  In the example, a sterile nutrient solution containing water, glycerol, glycocoll, corn steep liquor, secondary potassium phosphate, sodium chloride, magnesium sulphate, ferrous sulphate and calcium carbonate at a pH of 6.8 to 7.2 is inoculated with a preliminary culture of Streptomyces felleus and incubated for 6 to 8 days at a temperature of 29 DEG  to 30 DEG  C. with aeration and in the presence of an antifoaming agent, e.g. a dihydrocarbon siloxane.  The culture liquor is centrifuged and the filtrate adjusted to pH 8.0 and extracted with ether.  The ether extract is extracted with N/100 hydrochloric acid, the acid extract adjusted to pH 8.0 and then extracted with ether.  This is repeated. Hydrochloric acid gas is passed into the ether extract and picromycin hydrochloride precipitates.  Alternatively, picromycin may be isolated by (a) extraction of the concentrated culture filtrate with ethyl acetate, amyl acetate or ethyl alcohol; (b) chromatographic adsorption, and (c) ion exchangers.  The picrate may be obtained by reacting an aqueous solution of picromycin hydrochloride with picric acid.  Picromycin has the probable empirical formula C25H43O7N, molecular weight 458 to 470, and contains carbon 63.86, hydrogen 9.02, nitrogen 2.92 and oxygen 24.26.  It dissolves in concentrated sulphuric acid to produce an orange-red coloration that fades upon dilution with water with the formation of a flocculent precipitate. It is easily soluble in aqueous hydrochloric acid, acetone, benzene, chloroform and ethyl acetate; moderately soluble in ether and methanol; difficulty soluble in carbon disulphide, petroleum ether, water and aqueous alkali metal hydroxides.

Abstract: 768,109. Radio navigation. STANDARD TELEPHONES & CABLES, Ltd. (International Standard Electric Corporation). Nov. 3, 1954, No. 31764/54. Class 40(7) Relates to a phase-comparison ' radio-navigation system of the type in which the directional radiation pattern of a beacon transmitter (carrier frequency F), is rotated at a frequency f1 to produce at a mobile receiver a signal of fundamental frequency f1 whose phase rela-. tive to a reference signal of fundamental frequency f1 is dependent on the bearing of the receiver from the beacon, the reference signal being transmitted omnidirectionally from the beacon' by frequency modulating a subcarrier which is amplitude modulated on to a carrier of frequency F. According to the present invention, the bearing sensitivity is increasably shaping the beacon directional modulation pattern, Fig. 4, such that the waveform, Fig. 5, of the bearing-dependent signal at the receiver comprises the fundamental f1 and the third and fifth harmonies f3 and f5 of rotation frequency, corresponding. reference signals of frequency f1, f3 and f5 being modulated on to subcarriers having frequencies Fl, F3 and F5 respectively. The beacon, Fig. 2, comprises three horizontal loop aerials 18, 19, 20 spaced apart 11#/24. The two outer aerials 19, 20 are rotated about the fixed central aerial 18 at a speed of f1/=90 c/s by a motor 1b and'are energized in phase opposition from an R.F. oscillator 11 (frequency F=1,000 Mc/s), at 25 per cent of the energization level of the central aerial 18. Reference signals f1, f3 and f5 from generators 5; 6, and 7 synchronized with motor 16 are applied at 8, 9 and 10 to frequency modulate corresponding subcarriers F1, F3 and F5 which are applied together with an output from R.F. oscillator 11 to modulator 12 whose output is applied via bridge 21 to the central aerial 18. At the mobile receiver, Fig. 3, the bearing signal output, Fig. 5, from the detector 26 is applied through an amplifier 27 to a phase discriminator 28 and the subcarriers F1, F3 and F5 from detector 26 are demodulated at 29, 30 and 31 to give reference signals f1, f3 and f5 which are applied to the discriminator 28 through geared phase shifters 38, 39 and 40 controlled by a dial 46 which indicates the required bearing when it is adjusted to give a zero output from discriminator 28 as indicated on the centre-zero meter 55. The output from discriminator 28 varies with the setting of dial 46 as illustrated in Fig. 6 which shows that two null positions are obtainable, if there is a 180 degree ambiguity, but that the sensitivity is a maximum in the region of the nulls.
