Title: Electric wave filters
IPC: H03H7/01
Filed: 1920-04-21
Abstract: 142,115. Western Electric Co., (Assignees of Campbell, G. A.). July 15, 1915, [Convention date]. Repeating and amplifying systems; multiplex systems; simultaneous telegraphy and telephony. -Filter circuits for suppressing currents of certain ranges of frequency are composed of a series of similar sections, each including impedance in series and impedance in shunt. In the general form, shown in Fig. 1, each section consists of an inductance L1 and capacicy C1 in series and an inductance L2 and capacity C2 in parallel shunt. A network of this kind transmits two bands of frequencies f0 to f2 and f1 to f3, Fig. 8, with negligible attenuation, but practically extinguishes frequencies outside these limits owing to repeated reactions between the impedance units. The Specification contains a general mathematical investigation for enabling the dimensions of the various impedances to be calculated for any desired values of f0, f2, &c. The frequencies f1, f2 can be made to coincide, so that only a single band of frequencies is transmitted. The network shown in Fig. 1 can be simplified by omitting one or more of the impedances L1, C1, L2, C2 from each section, and by carrying this simplification to an extreme, as shown in Figs. 6 and 7, one of the limiting frequencies can be relegated to zero or infinity. Thus the circuit shown in Fig. 6 transmits all currents above and extinguishes all currents below a certain frequency, while the circuit shown in Fig. 7 has the opposite effect. The invention is applicable to wireless systems, multiplex high-frequency wire telephony, composite telegraph and telephone lines, and telephone repeater circuits. A two-way repeater system is shown in Fig. 10 with a filter in the in-put circuit of each of the thermionic valves 11. To prevent interaction between the two repeaters, the in-put circuit 8, 9 of each valve is connected between the line 3, 4 and an artificial line 20, which are equally and oppositely affected by the output transformer of the other valve. The use of filters in this arrangement renders it unnecessary for the artificial line 20 to simulate the transmission line except over the range of frequencies involved in telephonic speech.

Title: Clutches
IPC: F16D7/10
Filed: 1975-03-18
Abstract: 1501232 Overload release clutches F JOS LAMB CO and J H BREMS 18 March 1975 [6 May 1974] 11136/75 Heading F2C An overload release clutch for connecting driving and driven elements in a single angular driving relationship comprises a single torque transmitting roller 28 carried by a slot 26 in a driving sleeve 16 and urged into engagement with a single axial groove 30 in a driven element 18 by a circumferentially continuous elastic element 44 which is cylindrical in its unstressed state, the element 44 reacts against a roller or rollers 38, 40 diametrically opposite the roller 28 and carried by a slot or slots 34, 36 in the sleeve 16. On overload the torque transmitting roller 28 is cammed out of the groove 30 and during subsequent relative rotation between the driving sleeve 16 and the driven gear 18 the reaction roller or rollers 38, 40 are prevented from torque transmitting engagement with the groove 30 by, as shown, one of the rollers preventing the elastic element 44 from urging the other of the rollers into the groove 30 as it passes the latter. In Figs. 7 and 8 (not shown) a single reaction roller has a length which exceeds that of the groove in the driven element and thus is prevented from entering the groove. The resilient element 44 may, as shown, be provided within the sleeve 16 and urge the torque transmitting roller into a groove 30 in the inner periphery of a surrounding driven gear-wheel 18, or may, Figs. 5-8 (not shown), surround the driving sleeve and urge the torque transmitting roller radially inward into a groove in the external surface of a driven shaft. Additional rollers 46, 48 may be provided to prevent the elastic element from frictional engagement with the driving sleeve. To increase the torque transmitted a pair of cylindrical elastic elements, one within the other, may be provided. The inclined surfaces 32 of the groove 30 are parabolic in section to compensate for the increasing force applied to the rollers by the elastic element 44 during clutch disengagement. Disengagement of the clutch on overload may stop the driving motor.

Abstract: For the purpose of nitrating cellulose which has been prepared in a dense form as described in Specifications 322,998 and 323,019, [both in Class 2 (ii), Cellulose &c.], the cellulose is first treated with a nitration mixture in which the nitric acid preponderates but is not used in such high proportion as in the processes above referred to, namely, substantially lower than 81 per cent, the nitration being subsequently completed by the use of an ordinary nitration mixture. In the first stage of the nitration, a suitable mixture consists of 60 per cent of nitric acid, 20 per cent of sulphuric acid, and 20 per cent of water.  By the use of this method, highly nitrated products containing up to 13,4 per cent nitrogen can be obtained.  The cellulose may be obtained in a dense form either by the process of Specification 322,998, or by treatment with small proportions of carbon disulphide and caustic soda, followed by treatment with a hardening solution such as sodium bisulphite.

Title: Improvements in the manufacture and production of acetylene chlorides
IPC: C07C17/02
Filed: 1932-04-22
Abstract: Acetylene tetrachloride is prepared from gases containing acetylene, obtained by thermal or electrical treatment of other hydrocarbons or carbonaceous materials, by treating the gases with chlorine at a temperature between 80 DEG  C. and the boiling point of acetylene tetrachloride (147 DEG  C.).  The gases may be treated directly or after enrichment in acetylene.  A slight excess of chlorine may be used, and the gases and the chlorine may be preheated, preferably in tubes lined with aluminium.  The process may be effected at atmospheric, reduced or raised pressure.  In the examples, (1) gases from the treatment of methane in an electric arc are passed with chlorine at 110 DEG  C. up an iron reaction tower which is filled with silica bricks and pieces of wrought iron and down which acetylene tetrachloride is trickled; other chlorine carriers such as phosphorus pentachloride or p  antimony pentachloride may be used instead of iron; (2) the treatment described in example 1 is applied at about 85 DEG  C. to gases from the treatment of methane in an electric arc after enriching the gases in acetylene by treating them with acetone and expelling the absorbed gas.
