Title: Process for sulphonating higher fatty acids and fatty acid derivatives
IPC: C11C3/00
Filed: 1929-05-23
Abstract: 312,283. Naamlooze Vennootschap Chemische Fabriek Servo, and Rozenbroek, M. D. May 23, 1928, [Convention date]. Grant of Patent opposed. Sulphonic acids.-Higher fatty acids or their derivatives are sulphonated in the presence of salts of acetic acid or homologues or substitution products thereof. In examples, (1) dehydrated sodium acetate is treated with concentrated sulphuric acid and this mixture is used for the sulphonation of castor oil; oleum may also be used instead of sulphuric acid, or oleum or sulphur trioxide may be added to the reaction product of sulphuric acid and sodium acetate; (2) castor oil, sodium acetate and sulphuric acid or sulphur trioxide, chlorsulphonic acid, or oleum are treated together, the product being worked up in known manner. In the above examples the acid mixture obtained contains acetylsulphuric acid, which is advantageously converted to sulphoacetic acid by heating. Instead of sodium acetate, salts of this sulphoacetic acid may be used or salts of other substitution products of acetic acid, e.g., chloro-, oxy-, sulphocliloro-,' and sulphoxy derivatives as well as salts of the homologues of acetic acid and of their sulpho-, chloro-, oxy-, sulphochloro-, and sulphooxy-substitution products. Inorganic dehydrating means such as phosphoric acid, phosphorous acid, anhydrides, chlorides and oxychlorides of these acids, may be added to the sulphonation mixture. The Specification as open to inspection under Sect. 91 (3) (a) also states that the process may be carried out by starting with the free substituted acids, which are added to the sulphuric acid and after the reaction are converted into the salts, which may then again be used for subsequent sulphonation. This subjectmatter does not appear in the Specification as accepted. Specification 293,690 is referred to.

Filed: 1974-04-11
Abstract: 1499813 Wired broadcasting COMMUNICATIONS PATENTS Ltd 21 March 1975 [11 April 1974] 16226/74 Heading H4R In a signal adaptor for a wired broadcasting system a pilot carrier wave is derived from the broadcasting system and used to control the frequency of the output signals provided by the adaptor. As described the adaptor can be used to allow standard broadcast television or FM sound receivers to be used in the wired system. For television, broadcast programmes received over aerials 8 and 9 together with locally generated programmes from video cable 10 are transmitted at high frequency on respective pairs 4, 5, and 6 in cable 7, together with a crystal controlled locally generated pilot of about 20 MHz from oscillator 19. The signals may be received on special receivers 11, or on conventional VHF or UHF receivers 15 using an adaptor 16 which comprises a mixer 24, Fig. 2 (not shown) and a local oscillator (25) the frequency of which is determined by the received separated out pilot signal. The pilot and signal can be separated by a bifilar-T trap, Fig. 3 (not shown) and the oscillator may comprise a frequency multiplier, or a phase locked loop using a programmable counter in the loop. F or FM sound transmission a number of sound programmes can be transmitted on one line pair at 600 KHz spacing in the band 10 to 20 MHz with a 17À8 MHz pilot.

Title: Improvements in or relating to transistor detector circuits
IPC: H03D1/18
Filed: 1954-06-01
Abstract: 765,163. Transistor demodulation circuits. GENERAL ELECTRIC CO., Ltd., and BARRY, J. N. May 20, 1955 [June 1, 1954], No. 16232/54. Class 40(6) In a circuit in which amplitude modulated waves are rectified by the diode formed by the emitter and base of a transistor 1, the transistor is biased so that the emitter current is slightly below that corresponding to peak gain. The bias is such that maximum gain is, reached when the emitter current corresponds to an input having a minimum usable amplitude and is obtained by a choice of bias resistors 4, 6. The resistors are by-passed by capacitors 5, 7. Any further increase in input results in an increase in emitter current and decrease in gain to give an effected A.G.C. action. Since the input impedance of the transistor falls with emitter current the effective input signal rises more slowly than the received signal. A crystal diode 13 biased from potential divider 15, 16 in the conducting condition has an impedance which also falls with increasing input signal to give an enhanced effect as described in Specification 765,164.
