Title: Improvements in methods of and means for receiving telegraphic signals
IPC: H04B7/08
Filed: 1922-11-11
Abstract: 188,670. Marconi's Wireless Telegraph Co., Ltd., (Assignees of Ranger, R. H.). Nov. 12,1921, [Convention date]. Atmospherics and undesired signals, eliminating; heterodyne reeeiving systems; aerials.-In a system for minimizing the effects of interference, a message is received in a number of circuits differing in respect of some characteristic such as directional properties, distance, damping, type of detector, type of receiver, and is simultaneously recorded in adjacent positions. In an example, signals received at a station A are passed through an amplifier 4 and detector 5 and operate a relay 7, 8. This causes movement of a mirror 11 which deflects a spot of light on a travelling strip 13 and produces a record as shown at A', Fig. 2. In the case of stations B, C, signals are heterodyned by the sources 15 and the beat currents amplified by the amplifiers 16. During a signal the mirror 18 vibrates with the beat frequency and produces a record as shown at B<1>, C<1>, Fig. 2. The stations may use different heterodyne frequencies and the same or different beat frequencies, or may use different reception methods. In a further example, one station has a vertical antenna, another a loop, and the third a long horizontal antenna. Damped as well as continuous wave signals may be received. The Specification as open to inspection under Sect. 91 (3) (a) also describes a system in which the same message is received and recorded at different places, the records being compared subsequently. This subject-matter does not appear in the Specification as accepted.

Title: A method and device for continuous soap making
IPC: C11D13/04
Filed: 1950-12-22
Abstract: <PICT:0697244/III/1> A method for continuous soap-making in a plurality of consecutive stages comprises circulating the saponification reaction mixture in a separate circuit, introducing lye into the circuit at a point in advance of that at which fat is introduced, maintaining a holding zone between these two points, and continuously adding lye and fat, which are mixed in the circulating material, a quantity of saponified fat corresponding to the added volume of lye and fat being continuously led from the circuit to the next stage. Apparatus for carrying out the process is shown in Fig. 1.  Fat and lye, for example soda lye, are supplied, through pipes 12 and 13 respectively, to the saponification circuit and are circulated by pump 2 and heated by heater 5.  When tank 1 contains mainly saponified fat, pipe 14 is opened and part of the saponified fat passes to the graining stage.  A salt solution, for example, of sodium chloride, is added through pipe 26 and the mixture circulated by pump 15 and part of the mixture then discharged through pipes 22 and 23 to separator 21.  Glycerol, and small amounts of organic impurities, salts and soap are withdrawn through pipe 24 and neat soap is passed through pipe 25 to the fitting stage.  Lye and salt solutions are added through line 40 and the mixture is pumped through the circuit by pump 27 and is heated in heater 28.  Niger, consisting of a mixture of salts, soap and water is discharged through pipe 38, and neat soap is discharged from separator 35 through pipe 39 and may be further treated in a second fitting stage, from which soap is withdrawn through pipe 53.  Niger from the first fitting stage may be reintroduced after purification if necessary, into the circuits of the saponifying or graining stages, and niger from the second fitting stage may be recycled via pipe 56 to the first fitting stage. Apparatus is also described for operation of the saponification and graining stages at super-atmospheric pressure and the fitting stages at atmospheric pressure, and for operating the whole process at super-atmospheric pressure.

Abstract: 263,784. British Thomson-Houston Co., Ltd., (Assignees of Baker, W. R. G.). Dec. 29, 1925, [Convention date]. Wired-wireless systems; thermionic valve circuits.-In a system for controlling a circuit 14 by means of a carrier current supplied to the mains 1 of a distribution system, a relay 4, adapted to operate the switch arm 18, is connected in the output circuit of a thermionic valve 3 which is coupled to the mains 1 through a transformer 2 and condensers 6 adapted to exclude current of power frequency. The secondary of the transformer is tuned by a condenser 10 to the frequency of the carrier current and a battery 11 supplies negative bias to the grid so that normally no current flows in the output circuit of the valve. Current for the filament 9 is supplied through a transformer 15 by alternating current mains 17 or the mains 1. When carrier current is supplied to the mains 1 from a distant transmitter, the grid 8 is rendered positive and the relay 4 is energized to open the circuit 14. A relay 24 is included in the filament circuit so that in the event that this circuit becomes interrupted, the relay is de-energized to close an alternative circuit for the relav 4 which is maintained energized independently of the thermionic valve. The alternative energizing circuit of the relay 4 includes a two-eletrode discharge device 21 which passes current in one direction only.
