Title: Improvements in or relating to carrier wave generators
Inventor: NORMAN PETER
IPC: H04J1/06
Filed: 1955-11-28
Abstract: 780,152. Frequency changing systems. STANDARD TELEPHONES & CABLES, Ltd. Nov. 28, 1955, No. 34018/55. Class 40 (6). In an arrangement for generating a series of carriers having frequencies which are successive integral multiples of a frequency f, the outputs from two sources of basic frequency nf and mf (where n and m are different integers greater than 1) are applied to respective harmonic generators from the outputs of which a number of the desired frequencies are selected, the remaining frequencies being obtained by modulating one of the basic frequencies with appropriate ones of the selected harmonics. With this arrangement the filters for selecting the desired frequencies may have a wider band width since the nearest adjacent frequency may be spaced at least 2f from the desired frequency. The Figure shows an arrangement for generating the twelve carriers for a twelve-channel telephone system. The output from a 72 kc/s. oscillator is applied to two frequency dividers to produce outputs of 8 kc/s. and 12 kc/s. respectively. These are applied to odd harmonic generators and then to bridge rectifiers to add the even harmonics. From the output of these rectifiers a number of the desired frequencies are selected. The remaining frequencies are produced by beating the 12 kc/s. signal with the 80 and 88 kc/s. harmonics in separate mixers and selecting upper and lower modulation products. In an alternative arrangement the even harmonics are produced by connecting the bridge rectifier directly to the 8 and 12 kc/s. sources respectively Fig. 2 (not shown).

Title: Improvements in and relating to the manufacture of organic compounds by reactions involving replacement of substituent atoms or groups with liquid reagents
IPC: C07C37/02
Filed: 1922-12-16
Abstract: 212,970. Shannan, W. V., Siderfin, N. E., Adam, W. G., and Gas Light & Coke Co. Dec. 16, 1922. Nitranilines; phenols; dinitrophenol; substitution products, unspecified, obtained by passing reagent over layer of parent compound.-Organic substitution reactions are effected by heating a stationary layer of the one reacting substance with a continuously-moving liquid layer of the other reacting substance or a solution thereof. The moving layer, which will lie above or below the stationary layer according to the specific gravities, should dissolve the reaction product but be practically non-solvent upon the stationary material. The stationary layer is renewed in a continuous or intermittent manner; any conditions of temperature and pressure may be employed, and the reaction product is separated in any way, but when crystallisable is preferably removed by the process of Specification 211.556. The invention relates particularly to the production of o- or p-nitraniline by heating the corresponding nitrochlorbenzene with ammonia solution, and the interaction of chlor-benzenes with caustic soda to produce the corresponding phenols. The reaction vessel comprises a horizontally-disposed coil R<1> in conjunction with a vertically-disposed worm R, both of which are immersed in an oil-bath S heated by gas jets T. In the case of the production of p-nitraniline, a charge of fused p-nitrochlorbenzene is pumped from the feed tank X by the pump U into the coil R' so as to form a layer along the bottom of the coil. Ammonia solution is then drawn from the feed tank X' by the pump U' and is forced slowly over the layer of p-nitrochlorbenzene in the coil R<1>, then up through the worm R where any small quantities of dissolved parent material are completely converted, and the product finally discharged through the nozzle D into the apparatus described in Specification 211,556, in which the p-nitraniline separates in the crystalline form from the accompanying ammonia and ammonium chloride. The pressure in the reaction vessel is determined bv the degree of opening of the outlet valve V. In the case of the treatment of chlorbenzenes with caustic soda of greater specific gravity, the horizontally-disposed coil is superposed over the vertically-disposed worm. The reaction may be conducted at ordinary pressure, as in the manufacture of dinitrophenol from dinitrochlorbenzene.

Title: Improvements in or relating to electromagnetic relays operated at a low potential
IPC: H01H47/04
Filed: 1935-12-11
Abstract: 448,549. Electromagnetic switches. VEREINIGTE EISENBAHN - SIGNALWERKE GES., Blockwerk, Siemensstadt, Berlin. Dec. 11, 1935, No. 34380. Convention date, Dec. 12, 1934. [Class 38 (v)] A circuit arrangement in a railway installation for controlling an electromagnetic relay arranged to be operated at a low potential under the control of a wheeloperated contacting device which may be operated at high speeds includes a condenser connected to be charged or discharged upon operation of the said wheeloperated contacting device, the said condenser being so connected that in the first case the discharge and in the second case the charging of the condenser controls the operation of the relay. As shown in Fig. 1, the windings 1, 2 of a relay in series with a resistance 3 are shunted by a condenser 4 which, when a wheel treadle 5 is operated is charged, resistance 6 representing the line resistance The current flowing through the windings 1, 2 on closure of the treadle switch 5 does not sufficiently energize these windings to attract the armature, but when the treadle switch is again opened, the discharge of the condenser 4 through a circuit including the winding 2 and a condenser 7 supplies to the relay a sufficient number of ampere-turns to attract the armature with certainty. In a modified arrangement shown in Fig. 2, the condenser 8 is connected across the switch 5 in series with the relay 9 so as to be discharged when the switch is closed. The charging current on opening of the switch 5 passes through the relay 9 and lasts sufficiently long to cause the relay to attract its armature. A combination of the two methods Fig. 3 (not shown), may also be employed.

Class 103(6) The body 1 of a railway vehicle is mounted on a bogie by means of substantially spherical elastic bodies 23 which are arranged between rolling surfaces 8-11 connected to the pivot pin 2 of the vehicle and rolling surfaces 18-21 connected to the bogie frame 22, so that the rolling bodies have relatively free rolling movement in the vertical direction, their movement transversely in the direction B is against a progressively increasing elastic force, and their movement longitudinal of the vehicle in the direction A is limited to a small deformation of the rolling bodies. The pivot pin is supported rotatably in a two part bush 3 fixed in a sleeve 4 and vehicle movement of the pin in the bush is prevented by a retaining plate 5 and a castellated nut 7 screwed on the end 6 of the pin. The rolling surfaces 8-11 are welded to the sleeve 4. to upper and lower limiting faces 13 and 14 and to upper and lower reinforcing ribs 12.

Again a supply tube, segment and discharge tube may be formed from a continuous tube, the segments being connected by welding. The tubes 1 are arranged in a ring as shown (Fig. 2) and the segments and preferably the supply and discharge tubes are situated outside this ring. The segments may have larger internal diameter and wall thickness than the other tubes and the supply and discharge tubes may have larger internal diameter than the tubes 1.
