Title: Turbine power plant
IPC: F01K23/06
Filed: 1956-06-15
Abstract: 836,012. Turbine plant. FOIT, E. June 15, 1956, No. 18604/56. Class 110 (3). A combined steam and gas turbine power plant comprising a steam generator supplying steam to a turbine and a gas turbine comprising a compressor and combustion chamber supplying gas to a gas turbine has one or more heatexchangers separate from and heated by the gases from the combustion chamber in which the steam flowing to or through the turbine is heated and regulating means for varying the heat-exchange in the heat-exchangers for controlling the output of the plant whilst maintaining the load on the steam turbine unchanged. Air from a compressor K is heated by turbine exhaust gases in a heat-exchanger V2 and then supplied to a combustion chamber S1 fed with fuel by a conduit 1. The combustion gases pass through a heat-exchanger V1 to the turbine T1 driving the compressor K1 which exhausts through the heat-exchanger V2 to a second combustion chamber S2 supplying a turbine T2. The exhaust from the turbine T2 heats the feedwater of a steam generator G in a feed-water heater I. The steam from the generator G is supplied to the turbine T which is mounted on the same shaft as the turbine T2 and drives an electric generator E. The steam passing through the turbine T is reheated in the heat exchanger V1. Tappings II, III, IV, V supply bled steam to feed-water heaters. In a modification the steam is superheated before entering the turbine in the heat-exchanger V1 and the reheating of the steam is omitted. In a further modification, only one gas turbine is employed which turbine drives the compressor and a separate external load. In this arrangement the steam is superheated before entering the steam turbine and reheated in the turbine by heat-exchangers arranged in the path of the combustion gases. The steam turbine is operated at constant load and the plant output regulated by varying the temperature of the gases leaving the combustion chamber S1.

Filed: 1972-04-21
Abstract: 1389939 Digital transmission; testing GENERAL DATACOMM INDUSTRIES Inc 21 April 1972 18699/72 Heading H4P  In a method of testing the integrity of terminals and transmission paths, data from a transmitter is fed directly to a local receiver to check operation of both transmitter and receiver. Data may be also transmitted to a distant receiver and re-transmitted back to a local receiver to test the transmission path as well. In the embodiment described, one frequency mode F1 in a F.S.K. system is used for outward transmission of either transmitter and another frequency mode F2 for return signals. Switches 37A-37C are arranged so that when a station is originating a message transmission is at Fl, and reception at F2 which frequencies are reversed for inward messages by a ring detector 60 causing control 61 to reverse switch 37A-37C. In one embodiment for testing the transmitter and receiver are switched to operate at the same frequency and the transmitter output fed directly through an 80 db attenuator directly into the receiver input, which by examination of, e.g. a print-out, operation of transmitter and receiver for integrity can be checked. In a modification, a transmission loop test initiating signal may be applied to a terminal 78 either locally or from a distant end so that at the remote end signals are received at one frequency, e.g. Fl and re-transmitted at F2 to the originating station hence testing the complete system. A simplified arrangement is illustrated in Fig. 3 (not shown).

Title: Improved automatic frequency control device
IPC: H03D1/24
Filed: 1964-05-07
Abstract: 1,060,573. Automatic frequency control. R. L. KAHN. May 7, 1964 [May 28, 1963], No. 19020/64. Heading H3A. The A.F.C. system disclosed in Specification 982,178 is modified by the inclusion of phase detector and differentiating means for deriving the pulsed A.F.C. signal and improved means for storing the A.F.C. signal and maintaining its value when the carrier signal fades. The carrier signal at a nominal intermediate frequency of 100 kc./s. derived from limiter 36 is applied to a second limiter 40 in which it is mixed with a signal from reference source 42 and the limiter output is applied to a phase detector 46 of conventional form to which the reference frequency signal is also applied. The output of the phase detector is differentiated 50 to provide positive or negative pulses at a rate which is a function of the frequency difference between the I.F. and reference signals and of a polarity which is a function of whether the reference frequency is above or below the I.F. The pulses are applied to a circuit described in the Specification referred to which develops a conventional direct current A.F.C. voltage. This voltage is applied via an A.F.C. voltage storage circuit, Fig. 3, which when an adequate carrier signal is received is switched by relay CR to its operate condition in which the voltage is applied to a divider circuit which reduces its value to approximately one half before application to the grid of reactance tube 30. In this condition a capacitor 50 is charged to the full value of the A.F.C. input voltage. When a fade occurs the relay contacts change over and the voltage stored in capacitor 50 is applied via a voltage divider to the reactance valve grid. The charge on the capacitor maintains the grid voltage within a toleration range which gives the correct local oscillator frequency for a considerable period.

Moulding gums and resins. - For the production of clear, homogeneous compositions by pressing the condensation products of urea, thiourea or their derivatives with aldehydes, especially formaldehyde, the products are employed in a powdered form which is capable of swelling and which contains but little formaldehyde. For the removal of formaldehyde, the powdered products are washed with ammonia or other fixing agent, or the press is ventilated during the pressing operation; alternatively, the deleterious effects of the free formaldehyde are counteracted by adding dry ammonium salts, e.g. the sulphate, to the powder prior to pressing, or by the addition of such salts as accelerate polymerisation even in the presence of free formaldehyde. Fibrous and other filling materials may be added. The powders may be heated for a short time at high temperature before subjection to pressing, and if desired the composition may be only partially polymerized in the press with completion of the process by further heating outside, optionally under pressure.
