Abstract: 1,170,154. Monitoring the condition of shells and linings; heating granular material. CKD PRAHA OBOROVY PODNIK. 11 Jan., 1967 [12 Jan., 1966], No. 1428/67. Headings F4B and F4U. In a vertical shaft type heat exchanger wherein material to be treated is directed downwardly by an internal inclined baffle 3 constructed in the form of a steel shell covered with a protective insulating lining and which cooperates with a partition wall 5 of similar construction to define an annular passage 12, the condition of said shells and linings is continuously monitored by passing a stream of detection gas at a constant flow rate and temperature through the annular passage 12. Detection gas from a blower 9 enters the passage 12 through a feed line 6 and leaves the passage through a discharge line 7 having a thermometer 11 and flowmeter 10 therein. Failure, respectively of the lining or shell will produce a measurable change in respectively the temperature and flow rate of the detection gas exiting through the discharge line 7. A partition 8 in the passage 12 separates the feed lines 6 and 7. Hot treatment gas enters the shaft heat exchanger through an inlet channel 4 and flows upwardly countercurrent to the flow of material to be treated.

Abstract: 1,203,742. Automatic voltage control. BROWN, BOVERI & CIE A.G. Jan.10, 1969 [Jan.11, 1968], No.1584/69. Heading G3R. A D. C, voltage regulator of the type wherein a series transistor T1 is controlled by a variable gain differential amplifier 3 whose transistors T3, T4 are respectively fed with a reference voltage UV and a voltage obtained from a divider R7, R8 across the output terminals 2, 0, is provided with forward-acting regulation responsive to variations of the input voltage at terminals, 1, 0 and comprising the circuit members T2, R1---R5 which control the transistor T1 to make the output voltage independent of these variations. The Specification discusses the design considerations affecting the choice of the voltage dividers R1, R2 and R4, R5 and of the tapping position of the latter to provide stable operation of the transistor T1. The tap position is determined from assumed parameter relationships between members T1, R3---R5 and the small-signal output conductance of transistor T1 and from an equation relating these parameters and those of members R1, R2 and the small-signal current amplification of transistors T1, T2. If transistor T1 is replaced by a cascade circuit comprising a plurality of transistors, then the divider R1, R2 is of high resistance to reduce the power loss. In a modification to provide improved temperature stability, Fig. 2 (not shown) the transistor T2 is combined with a further transistor and resistor to form a differential amplifier of which the further transistor is connected with its basecollector circuit across the resistor R1.

Abstract: 283,933. Armaturen-&. Maschinenfabrik Akt.-Ges. vorm. J. A. Hilpert. Jan. 20, 1927, [Convention date]. Pumping-machines; cooling. - The arrangement described in the parent Specification for cooling a water ring pump associated with a centrifugal pump is modified so that fresh water from a tank can be introduced into the water ring pump for cooling purposes. The evacuation duct 3 between the centrifugal pump 2 and the other pump 1 has a two-way cock 10 from which a pipe 11 extends into the water tank 8. The exhaust pipe 4 of the pump 1 can be connected by a bye-pass to the pump 2, or to the water tank 8, or to the open discharge pipe. The starting proceeds in the usual manner, air being drawn from the centrifugal pump 2 through the duct 3 and discharged from the pipe 4. At the end of the starting stage the cock 10 is turned so that the air pump suction is in communication with the tank 8 through the pipe 11. The pump 1 then draws cooling water from the tank 8 and discharges it through the pipes 4, 9 back to the tank. In a modification, an inverted U-shaped standpipe 12 is connected to the duct 3 by a cock 13. When this pipe 12 is included, its height prevents liquid in the system of the pump 2 from reaching the air pump 1, so that the latter pump is protected from sand, contaminated water or the like. Specification 242,985 is referred to.

Abstract: 732,354. Automatic exchange systems. LICENTIA PATENT-VERWALTUNGS GES. Jan. 22, 1952 [Jan. 22, 1951], No. 1812/52. Class 40 (4). Impulses are reverted from a position P to a main position Q by a relay selector, the relays of which are arranged in a chain. The chain relays step automatically when continuous battery is applied to a control line La by a switch Sch at the main position. The impulses operate the driving magnet DM of a step-bystep switch M until test relay C disconnects battery or until La is grounded by a marking contact T4 at P.. The chain relays are selfholding relays which remain operated by residual magnetism when the excitation is removed. Chain relay contacts in the circuits controlled by the selector are not shown. Relays A, B (only contacts are shown) are operated when the selector is in use. When the switch Sch is closed, relays S1, J, I, O are energized in series but only S1 operates at first and short-circuits its high resistance winding. Relays I and J then operate and O follows after a short delay to interrupt the circuit and thereby to restore both S1 and J. Relays S2, J, II are energized in series with the release winding I(R) of relay I, and S2 operates. Relays II and J operate and the circuit is interrupted as relay I falls back. The relays I, II, III, &c. are operated and released in succession until battery is cut off either by test relay C or key T4, the latter being operative as shown, when relay IV operates. The chain is stepped to normal automatically when battery is connected again to the chain either :by opening T4 or by restoring C, the last relay X being released when winding X(R) energizes in series with resistance W. The chain may alternatively be returned to normal by a release relay Ab which energizes the release winding of the last operated chain relay.
