Filed: 1925-02-19
Abstract: 252,245. Siemens Bros. & Co., Ltd., and Humphries, H. E. Feb. 19, 1925. Drawings to Specification. Automatic exechange systems.-In a system in which a counting device (which may be a relay chain) controls the transmission of impulses to selectors while hunting for a point marked by a register, the arrangement is such that the counting device begins the control of each digit from the position in which it terminated the preceding digit. Each of the registers therefore gets a preliminary setting before receiving its digit, corresponding to that of the preceding register. After each digit, the sending of the next is held up until a signal is received from the selector. The invention is described with reference to a code translating register-controller of a type in which the register-controller and the selectors are mutually controlled by forward and reverting impulses with means for sending up to three routing digits and means for routing calls in response to special single digit and two digit numbers. The system described is identical with that described with reference to Figs. 5 to 8 and 11 in Specification 252,244. Specification 200,928 also is referred to.

Title: Improvements in apparatus for training and firing guns
IPC: F41G5/00
Filed: 1941-04-11
Abstract: 548,550. Controlling and actuating apparatus by sounds, HERZMARK, N. April 11, 1941, No. 4852. [Class 118 (ii)] Apparatus for training and firing guns comprises a number of microphones for the detection of an attacker, motors controlled by the output of the microphones for training the microphones and a gun or guns on the attacker, and means whereby the convergence of the intersecting axes of the detectors prepares or completes the fire-control circuit. Fig. 1 shows an arrangement for destroying an approaching torpedo E by discharging a depth charge or projectile from a gun G mounted on a ship. Sound detector units A, B, C are mounted at the ends and in a mid position on each side of the ship. The axes of the detectors A, C follow the moving torpedo, and when they intersect on a circular arc F at a predetermined distance from the ship, a stick of small bombs is discharged automatically from the gun G which is trained in the correct direction by the detector B. Each detector may consist of two microphones each carried in a tube a, or a<SP>1</SP>, Fig. 3, the tubes being secured at an angle to one another and mounted on a pivoted support D which is rotatable about a vertical axis by a hydraulic motor M. The output of each microphone is passed through an amplifier H or H<SP>1</SP> to coils i or i<SP>1</SP>, respectively, of a relay I. This relay switches a current to one or the other of two opposed solenoids k, k<SP>1</SP> which move an armature K<SP>1</SP> connected to the plunger L of a valve L<SP>1</SP> that controls the direction of rotation of the motor M. The difference in the volume of sound received by each microphone causes the motor to move the detector until both tubes a, a<SP>1</SP> receives the same volume of sound, when the relay I breaks the circuit of the solenoids. The axis A<SP>1</SP> of the detector is then directed on the target E. Coupled with the shaft of the motor M is a switch arm P that slides over a series of contacts P<SP>1</SP>, the angular movement of the arm being arranged to coincide with that of the detector. The arm P of the detector B controls the training of the gun G, and the contacts of the detectors A, C are so connected to one another and to the firing circuit that the gun is fired when the axis of the three detectors intersect on the arc F. The device may be arranged to fire guns on land at approaching tanks. Microphones of the ribbon type may be used to eliminate the disturbing effect of noises coming equally from all around the detectors.

Filed: 1930-02-13
Abstract: 345,431. Roasting &c. furnaces. DAWANS, A., 24, Quai de Rome, Liege, Belgium. Feb. 13, 1930, No. 4869. Convention date, April 6, 1929. [Class 51 (ii).] Self-burning ores or ore mixtures are roasted or agglomerated on a hearth which is moved in a direction opposite to that in which combustion is propagated in the mass of material, and at such a rate that the combustion zone remains stationary. In the furnace shown the treatment chamber is formed between a rotary drum 3 and a fixed cover 4. The ore is fed on to the drum at its highest point through a shoot 2, and moves away from suction pipes 5 by which the air for combustion is drawn through the charge. The chamber is sealed at the sides and at the feed end by flexible strips 6, 6a, and the shoot is sealed at the upper end e.g. by a double valved hopper. The cover 4 extends round only a part of the drum so that the roasted ore will fall from the hearth by gravity. The position of the combustion zone can be shifted by varying the speed of rotation for a short time, and the roasting operation is controlled by separate dampers in the suction pipes 5, and by varying the proportion of combustible material in the charge. The diameter chosen for the drum may vary for different materials.
