Title: Improvements relating to apparatus for the homogenization of pulverulent material, slurry and the like
Inventor: ZAHRADA FRANCIS
IPC: F16K31/40
Filed: 1960-01-21
Abstract: 939,060. Mixing appliances. PREROVSKE STROJIRNY, NARODNI PODNIK. Jan. 21, 1960, No. 2168/60. Class 86. [Also in Group XXIX] Cement in a silo 90 is homogenized by compressed air from a pressure source 80. The air is controlled by an electromagnetically actuated valve 40 remotely operated from a switch box 1. The electromagnetic device operates an auxiliary valve which admits the controlled fluid to a cylinder to open the main valve against the action of a spring, by which it is closed. In the valve, Fig. 1 (see also Group XXIX) the compressed air supply is connected to the inlet chamber 2 from which leads the elbow pipe 54. There is an electromagnet 51 which when energized attracts an armature 67 raising the piston rod and piston 50, 71, thus admitting compressed air from the elbow pipe 54 to the passages 64, 65, 62 and thence under the piston 48. The piston moves upwards against the action of the spring 45, raising the valve member 53 from its seat 58 and admitting air from the inlet chamber 2 in the valve body 42 (see also Fig. 2, not shown) to an outlet chamber 3 which communicates with the pipe 75 to the silo. When the current to the electromagnet is broken, the piston 50 is returned by spring 52 placing the passages 9, 63, 62 into communiontion and thus venting to atmosphere the space 61 under the piston 48, which together with the valve member 53 is returned to the closed position by spring 45. The pressure exerted by the spring may be adjusted by screw 47. In another arrangement, Fig. 4 (not shown), a known solenoid valve controls the admission of air to the main valve through a pipe having a bleed hole too small to prevent actuation of the main valve but through which air may vent when the solenoid valve is de-energized.

Abstract: 211,119. British Thomson-Houston Co., Ltd., (Assignees of Oompagnie Fran- þaise pour l'Exploitation des ProcÚdÚs Thom. son-Houston). Feb. 7, 1923, [Convention date]. Electromagnetic interrupters. - Voltage regulators of the vibrating t y p e are made independent of the increased resistance of the exciting winding due to the heating effect of the current therein by means of a magnetic shunt to the magnetic circuit which decreases its permeability when warmed up by the exciting coil. As shown, the exciting coil 14 connected across the generator 16 is wound on the limb 11 which serves to attract the armature 12. The armature is provided with a contact 18 which intermittently short-circuits a resistance 17 in the field circuit winding 16 in the usual way. When the exciting winding 14 warms up, the current in it is reduced but the magnetization remains constant owing to the warming up of the magnetic shunt 21 cooperating with the adjustable pole 22. In the warmed condition less of the flux is shunted from the armature.

Title: An improved alarm system, more especially a burglar alarm system
Inventor: HOGBIN ARCHIBALD
IPC: G08B13/22
Filed: 1950-02-01
Abstract: 678,529. Burglar alarms. RELY-A-BELL BURGLAR & FIRE ALARM CO., Ltd. March 9, 1951. [Feb. 1, 1950; June 16, 1950] Nos. 2653/50 and 15169/50. Class 118 (i). In an alarm system, more particularly a burglar alarm, in which the alarm is operated on the interruption of a closed circuit, operation of the setting switch moves the armature of the closed circuit relay into its attracted position, but further operation of the switch to complete the setting operation is prevented if the armature is not then retained in its attracted position. Fig. 1 shows the side view of a setting switch, and Fig. 2 the rear view of the switch and the circuit of a burglar alarm system. The system is set in the alarm condition by means of key K which is used 15 rotate the switch and associated arm H 360 degrees. Rotation of arm H mechanically moves the armature L of relay C into its attracted position, and allows contacts a1 and a2 to make during the rotation. The arm H of the key switch has a detent N, so that if, owing to a fault, the armature L is not held in its attracted position, the armature engages the arm H to prevent further rotation of the switch and thus warn the operator. A bolt E associated with the switch causes contacts a3, a4 and a5, a6 to remain operated after the completion of the rotation. The setting operation establishes a closed circuit including a battery V2 and the coil of relay C which carries a small but sufficient current to hold the armature L in its attracted position. The closed circuit includes a number of door or window contacts W which are opened on the entry of an intruder, so that the closed circuit is broken. The resulting release of relay C causes an alarm T to be operated from a battery V1, the circuit being established through contacts C2, C3 and a3, a4. The arrangement for setting the system in the alarm condition includes 'final door' contacts f1, f2 which are closed when the person setting the alarm leaves the building, and a 'short circuiting' relay S, which having been operated by contacts a1, a2 of the key switch to close contacts 51, 52 and 53, is released by operating push button switch R which is situated outside the final door. The alarm may consist of a message transmitted to a remote point.

Abstract: 547,498. Valve generating circuits. STANDARD TELEPHONES & CABLES, Ltd., and WILLOUGHBY, E. O. Feb. 28, 1941, No. 2749. [Class 40 (v)] In a single valve ultra short wave oscillator having transmission line tank circuits coupled to the grid and plate electrodes, a trimming condenser tied to the plate line is provided to balance the grid and plate transmission lines to cathode. Fig. 2 shows an arrangement with the output co-axial line LO tapped to the plate line AL, trimming condenser Cb being adjusted to rebalance the lines. Since the inductance L of the cathode lead only carries the out of balance current it may be neglected provided the lines AL, GL are of correct length and balanced. Alternatively a small condenser to tune may be connected across the lines. Fig. 3 shows an arrangement in which series condensers C1, C, both balance and trim, the difference C1-C2 being the balancing capacity and the series value, namely C1, C2/C1+C2 being the trimming or tuning adjustment. With valves of a large amplification factor a high grid leak may be necessary to prevent excessive grid swing unless a capacitive reactance, which may be a condenser or a length of transmission line, is placed in the cathode lead. The single valve may be replaced by a number of valves in parallel.
