Title: Improvements in or relating to rotary switches of the type used in automatic telephone systems
IPC: H01H67/06
Filed: 1943-01-26
Abstract: 560,552. Automatic exchange systems; switches. STANDARD TELEPHONES & CABLES, Ltd. Jan. 26, 1943, No. 1283. Convention date, Feb. 5, 1942. [Class 40 (iv)] [Also in Group XXXVII] In a system in which a common line relay is associated with telephone lines in turn by a constantly rotating switch, the latter keeps its wipers and terminals bathed in oil. When a subscriber calls, he applies a marking potential via his hook switch and resistances L, K, J to his terminal in the constantly rotating switch, the wiper D of which is connected to the grid of a tube V the anode relay X of which is normally energized. When the wiper encounters a marking potential, however, X falls and energizes Y which, directly or with the help of a relay P, energizes the driving magnet of a finder which has previously been allotted in known manner. The c wiper of this finder, which picks up the marking potential via resistances L, K and the loop, is connected to the grid of a tube V1 in a common testing set. When the calling line is reached, the anode relay X<1> of this tube falls back and energizes Y<1> which energizes the switching relay R. The latter is held thereafter by the feed relay Q. Construction of switch. This comprises a moulded cylindrical part in which the terminals 2 and collector rings 5, 6 are mounted and which is provided with a well containing oil. The wipers, which are carried by a rotary arm 14 and are urged into contact with the terminals by springs 15, dip into the oil. The cylindrical part is closed by a cover plate formed with an oil-filled chamber which contains the gearing by which the power shaft is coupled to the wiper shaft and in the walls of which are mounted ball bearings for the respective shafts.

Title: Improvements in microphones
IPC: H04R1/34
Filed: 1941-01-31
Abstract: 545,790. Sound-directing appliances. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Jan. 31, 1941, No. 1326. Convention date, Jan. 31, 1940. [Class 13] [Also in Group XXXIX] Relates to directional microphones of the kind in which the sound is picked up at a number of points, for example by a number of open-ended tubes communicating with a common diaphragm as in Specification 479,328. In order to make the directional characteristic less dependent on the frequency of the sound received, the pick-up tubes or other devices are divided into groups, each group being effective over a different frequency range, and one or more groups of the tubes &c. is associated with an acoustic filter. In Fig. 1, the two groups of tubes 9, 11, responsive to low and high frequencies respectively, are coupled through lowpass and high-pass acoustic filters, 13, 23 with the diaphragm 3 of an electro-dynamic microphone. The low-pass filter 13 comprises a cylindrical tube with an apertured partition 15, and the high-pass filter 23 comprises a cylinder with two openings 25, 27 in one side thereof. In a modified arrangement Fig. 2 (not shown), the tubes 9 are arranged in a circle around the tubes 11. When more than two groups of tubes are used, the intermediate groups terminate in band pass acoustic filters. In a further modification shown in Figs. 4 and 5 (Fig. 4 being a developed view) the tubes of the several groups are symmetrically arranged in relation to a circular diaphragm. The three shorted tubes 31a, 31b, 31c constituting one group are arranged as shown in Fig. 5, as are also the groups 33a, 33b, 33c; 35a, 35b, 35c ; and 37a, 37b, 37c. Further groups 39, 41, 43 are arranged as shown. The tubes of each group terminate in similar acoustic filters 36, 42, 48 &c. With the usual pressure-actuated microphone, the output will decrease with rising frequency; this may be avoided by using a condenser or crystal microphone feeding a resistance equal to the microphone impedance in the highest frequency, or by using a stiffness-controlled dynamic microphone.

Title: Process for the manufacture of formates
IPC: C07C51/10
Filed: 1926-01-16
Abstract: 246,168. Soc. l'Air Liquide, Soc. Anon. pour l'Etude et l'Exploitation des ProcÚdÚs G. Claude. Jan. 17, 1925, [Convention date]. Alkali and alkaline earth metal formates.-Carbon monoxide or the carbon monoxide content of a gaseous mixture is converted into alkali or alkaline earth formate by absorption in solutions of caustic soda or potash, or suspensions oi the hydrates of alkaline earths, either in water or in a solution of alkali carbonate under a pressure of over 300 atmospheres and at a temperature of the order of 400‹ C. The gas and the liquid may be preheated at the expense of the reaction heat. The process is especially applicable to the removal of carbon monoxide from mixtures of hydrogen therewith, which are obtained by partial liquefaction of such gasee as water gas; the residue may be added to fresh water gas and re-subjected to liquefaction. As shown, the liquid is forced through the pipe a into the interior of a pressed vessel containing an inner reaction chamber C, into which it passes by the opening b and leaves by the pipe c. The compressed gas enters the reaction chamber C by the pipes d, T and issues by the pipe f, after coming into contact with the liquid flowing in countercurrent through the chamber. In rising round the chamber, the liquid becomes heated by the reaction heat; the entering gases, too, become preheated. before coming into contact with the solution. The reaction chamber, which may be in the form of a removable cartridge, contains filling materials and plates. The tube T and inner wall of the reaction chamber are made of a metal such as copper, which does not assist the undesirable decomposition of the carbon monoxide into carbon dioxide and carbon; the walls of the pressure-resisting tube, however, may be of iron or nickel steel, since they are only in contact with the liquid. The apparatus may be provided outside with electric heating means for starting and controlling the reaction. Caustic soda solution may be prepared in situ by lime treatment of sodium carbonate. The Specification as open to inspection under Sect. 91 (3) (a) comprises also (1) the use of remaining gas mixtures of nitrogen and hydrogen for the synthesis of ammonia; (2) avoidance of the heating of the outer tube by using less concentrated solutions and providing an inner electric heating device; and (3) extension of the process to the removal of carbon monoxide from water gas itself by using more highly concentrated alkaline solutions and operating under higher pressures, e.g. those obtaining in the ammonia synthesis. The resulting mixture of nitrogen and hydrogen, after removal of water vapour by cooling, can then be used directly for ammonia production. Any carbon dioxide present in the water gas is previously removed in water or ammonia or by partial liquefaction, and additional nitrogen may be added to correct the proportions. In the same way may be treated the gas mixture which is obtained when coke oven gas is passed over glowing coke. This subject-matter does not appear in the Specfication as accepted.

Title: New or improved means for controlling the direction of movement of moving bodies
IPC: F41G7/00
Filed: 1940-01-25
Abstract: 540,906. Controlling apparatus for sounds. SHAW, W. Jan. 25, 1940, No. 1495. [Class 118 (ii)] Relates to means for controlling the direction of a moving body, such as a small aeroplane or torpedo, by the reception of sounds by microphones carried on the body. According to the invention, two microphones spaced apart actually control, through amplifiers el, e<SP>2</SP>, two motors c<SP>1</SP>, c<SP>2</SP> which operate an elevator f through differential gearing d, while another pair of microphones, spaced apart horizontally, similarly control a rudder. The controlling means may be used for directing automatically a projectile towards a target from which sounds emanate, or for automatically steering a torpedo towards a ship. The moving body may be guided during the first part of its travel by firing in the desired direction shells that make more noise in their flight than usual.

Title: Improvements in electric filters and other impedance systems
IPC: H04B1/18
Filed: 1934-01-19
Abstract: 427,913. Impedance networks. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN, Emmasingel, Eindhoven, Holland. Jan. 19, 1934, No. 1986. Convention date, Jan. 30, 1933. [Class 40 (iii)] A star or delta network is connected so that two of its arms are in parallel or in series, as the case may be, with an oscillatory circuit, filter, or other impedance and these two arms are so calculated that the product of their impedances divided by that of the third arm has a negative resistance component. The star a, b, c, Fig. 1, is equivalent to a delta x, y, z, Fig. 2, if y=c+a+ca/b and x, z have corresponding values. The values of a, band c are so chosen that the real part or resistance component of y is negative ; and this condition is fulfilled in certain cases in which one arm of the star is a resistance while the other two are reactances, Figs. 3-6 (not shown). Thus an acceptor circuit containing resistance, Fig. 7 (not shown), in parallel with two arms of a star can be made to have a perfect rejector effect. Again a rejector circuit Lo, Co, Ro may have its resistance neutralized as shown in Fig. 8, where b is a resistance R while a and c are condensers C1, C2. The damping can be regulated independently of the tuning by adjusting R. Other examples using the star connection are described, Figs. 9, 10, (not shown), and the Specification states that the invention can be applied in an analogous manner to delta networks, Figs. 11, 12 and 13 (not shown). The networks may comprise mutual inductances. In a wireless receiver, Fig. 15, the arm b of a star may be a resistance R, while the arms a, c are the two halves of an inductance coil L which forms a rejector circuit with condenser C1 for eliminating an interfering signal ; or, Fig. 17, the arm y of a delta may comprise the resistance R, the arms x, z being the condensers C1, C2. Resonant resistance-capacity and inductancecapacity circuits. A network simulating an inductance consists of a star containing two resistances R1, R2 and a capacity C, Fig. 19 (and Fig. 18, not shown). This may be combined with a star comprising one resistance R and two condensers Cl, C2. In the delta equivalent to the first of these two stars, the arm y has the value R1 + R2 + jpCR1R2 and so has the properties of an inductance and resistance in series ; while in the delta equivalent to the second of the stars, the arm y simulates a condenser with negative resistance, so that the two parallel fictitious arms y connecting the points A and C in Fig. 19 simulate a resistanceless rejector circuit. Similarly, a capacitance can be simulated by means of inductances and resistances ; and similar principles can be applied to delta networks, Fig. 20 (not shown).
