Title: Improvements in or relating to systems for eliminating interference in radio receivers
IPC: H03G5/24
Filed: 1940-01-27
Abstract: 536,041. Valve circuits for wireless reception. PHILIPS LAMPS, Ltd. Jan. 27, 1940, No. 1713. Convention date, Jan. 30 1939. [Class 40 (v)] In a radio receiver, side-band interference by neighbouring stations is avoided by the provision of means which eliminate at any instant the side band which is most disturbed at that instant. The intermediate frequency oscillations from a receiver B pass to two channels C, D, E and C<SP>1</SP>, D<SP>1</SP>, E<SP>1</SP>, which pass the carrier and the upper or lower side band respectively which are fed to a low-frequency amplifier F and loud-speaker G. The output from B also passes to two further parallel channels H, K. H<SP>1</SP>, K<SP>1</SP> in which H and H<SP>1</SP> are filters which pass respectively the extreme side bands which are rectified at K, K<SP>1</SP> and pass to a change-over device L which, with a slight time delay, applies a prohibitive bias to C or C<SP>1</SP> according to the relative intensities of the currents detected by K, K<SP>1</SP> respectively. This blocks the channel which passes that side band which is the more disturbed.

Title: Improvements in or relating to the catalytic synthesis of ammonia
IPC: C01C1/04
Filed: 1925-01-21
Abstract: 241,771. Dicker, S. G. S., (Harter, H., and Otto, A. T.). Jan. 21, 1925. Catalytic apparatus; ammonia, catalytic production of from nitrogen and hydrogen. - In the catalytic synthesis of ammonia, part of the reaction mixture is treated at high pressure (above 400 atmospheres), and the remainder at low pressure (below 400 atmospheres), the products being united for the removal of the ammonia by liquefaction. In a suitable arrangement of plant, nitrogenhydrogen mixture is passed from a gas-holder 1 through a water-trap 2 to a compressor 3 which delivers the gas to a high-pressure tube 4 and a low-pressure tube 5. The tubes 4, 5 each contain a catalyst and the tube 4 has, in addition, internal heating means. The heat of reaction generated in the tube 4 maintains the catalyst in the tube 5 at the necessary temperature, and to this end the pressure in the tube 4 is adjusted, if necessary. The products from the tubes 4, 5 pass to a liquefier 7, the product from the tube 4 passing first through an expansion valve 6 whereby the gases are sufficiently cooled. The gases leaving the liquefier 7 may be passed over silica gel to remove traces of ammonia, and may then be returned by way of the pumps 8, 9 to either of the tubes 4, 5 or to the water-trap 2. One liquefier 7 may be common to several such constructions arranged in parallel to form a " battery," and several batteries, having a successively decreasing number of units, may be arranged in series, the gases remaining after removal of ammonia passing from one battery into the next. The construction shown in the Figure may be modified by replacing the tube 5 by a coiled tube surrounding the tube 4 or by arranging the tubes 4, 5 in juxtaposition, and in place of hydrogen impure gases, such as coke-oven gases, may be used.

Abstract: 718,366. Switching systems; supply systems for consumption apparatus. BRITISH THOMSON-HOUSTON CO., Ltd. Nov. 28, 1951 [Jan. 26, 19511, No. 2067/51. Class 38(4) Apparatus for obtaining a succession of electrical impulses from a constant voltage D.C. supply, and providing for the independent adjustment of pulse duration, interval between pulses and interval between operation of an initiating switch S and the commencement of the first pulse of the train, comprises thermal switches T1-T3 and timing resistors R1-R4. The arrangement is such that with switch S in the "off " position shown, the heater of T3 receives sufficient current over R4 to maintain normally-closed contacts t3 open. Operation of switch S to its other position energizes the heaters of the other two relays over contact S1 after a delay determined by R3, which is now effective to reduce the current through the heater of relay T3 to a value inadequate to maintain contacts t3 open. After a further delay, determined by the settings of R1 and potentiometer P the normally open contacts t1 of relay T1 close, so that the output terminals are now connected to the source over contacts t1-t3. Additional heater current is also supplied to relay T3 over the " pulse interval " timing resistor R2. Subsequent disconnection of the output terminals from the source occurs when the normally-closed contacts t2 of relay T2 open-after a delay determined by P. Contacts t3 eventually open (due to the additional heating current supplied over R2) and relays T1, T2 return to theirinitial conditions. The additional heating current for T3 is thereby terminated, causing contacts t3 to reclose and initiate another cycle of operations, which repeats until switch S is restored to its " off position: Several modifications are described.

Title: Improvements in petrol-starting means for heavy oil engines
IPC: F02N99/00
Filed: 1950-01-31
Abstract: 667,871. Starting; cylinders. ETABLISSEMENTS IRAT & CIE. Jan. 31, 1950 [Feb. 1, 1949; April 11, 1949], No. 2467/50. Classes 7(ii) and 7(v) In an arrangement for the petrolstarting of heavy oil engines there is provided means, such as a handle 25, Fig. 2, exhaust valve rocker arm 11, an eccentric 13 and main exhaust valve 9, for permanently connecting, during starting, a cylinder of the engine with the exhaust duct 8 associated with that cylinder, and means, such as an auxiliary valve 23, for alternately sealing and opening to exhaust, in synchronism with the engine cycle, a portion of the exhaust duct adjoining the - cylinder to form an auxiliary combustion chamber in communication with the cylinder. The outer extremity of the exhaust duct 8, has fitted therein a sleeve 22 which houses the auxiliary valve 23 that is operated through a rocker arm 31, an auxiliary push rod 30 and a lever 29 from a main push rod 12, which normally actuates the exhaust valve 9, only when a handle 25 is in the position shown. In being moved to this position the handle rotates the rocker arm 11 through its eccentric shaft 13 and thereby opens the valve 9, at the same time conjointly closing a throttle valve 17 in a passage 16 leading to the intake duct 6, opening a choke 18, in order to supply petrol-air mixture to the intake manifold, closing an ignition circuit to a sparking plug 20 in duct 8 and rendering a fuel pump 5 inoperative thereby preparing the engine for petrol operation. When the engine has started after being turned over by hand or otherwise the handle 25 is moved rightwardly so returning the valve 9 to its seat and enabling it to be normally operated from rod 12, closing choke 18, opening both throttle 17 and the ignition circuit and setting the pump 5 to supply fuel to an injector 4. By a quick release arrangement the valve 23, sleeve 22 and rocker arm 31 are returned and a closing sleeve inserted in its place, the sleeve having a part which covers the end of the sparking plug protruding into duct 8. The push rod 30 is no longer operated since a spring 29b draws the lever 29 out of engagement with a flange 12a on the rod 12 and the engine now runs normally on the diesel cycle with its compression ratio increased from 5-6:1 to 15:1. In a modification, the normal exhaust valve 103, Fig. 7, is operated as in Fig. 2, the auxiliary valve 114 being moved by a handle (not shown), either to the perol-operation position illustrated or to a lower position for diesel operation on to a seat 110 where it covers the sparking plug 111, in which location the valve stem 114a is not contacted by the auxiliary rocker arm 122; the latter becomes inoperative due to a spring 125a causing upward movement of a lever 125 as in Fig. 2. The apparatus may be provided in respect of any desired number of cylinders in a given engine.

Abstract: 380,342. Pasteurizing liquids. FEHRMANN, K., 20, Juchostrasse, Dortmund, Germany. Jan. 27, 1932, No. 2530. [Class 49.] Apparatus for pasteurizing wort, beer, milk and other liquids, consisting of a heater for the liquid connected to coolers, is sterilized by passing the liquid, which has been raised in the heater to the temperature necessary for destroying germs, through the subsequent sections of the plant, the cooling being out of action. In the construction described, in normal operation the liquid is forced by a pump 13 from a storage receptacle 15 through a pipe 12 to a heat exchanger 4 in which it is heated by hot liquid in pipe 8 coming from the heater 3 and from which it passes through a pipe 11 to the pipe 8 which conveys it in turn through the heater 3 in which it is raised to pasteurizing temperature by steam or hot water, the heat exchanger 4, and the coolers 5, 6. In sterilizing the plant, the heat exchanger 4 is byepassed by operating a valve 19 to connect the pipe 12 directly to the pipe 11 through a pipe 26, the milk passing directly to the heater 3 and being then passed through a valve 20a, pipe 21, and a valve 24 either back to the receptacle 15 through a pipe 22, or to a separate collecting receptacle 25 through a pipe 23. A throttling member 28 in the pipe 12 is set to a small opening. When the desired temperature is attained, the valve 20 is operated to connect the heater 3 to the heat exchanger 4 and coolers 5, 6 to sterilize the pipe 8 therein, the supply pipes 9 for the cooling medium being closed. The liquid is passed through the apparatus and back through a cock 18 and pipe 17 to the receptacle 15 until the liquid leaving the cooler 6 has reached the desired temperature, after which normal working may be resumed. If a bottle-filling machine or other device is employed after the last cooler 6 it is included in the sterilization and provided with means for returning the liquid to receptacle 15. If, in the normal working, the liquid leaving the heater 3 falls below the necessary temperature, the cock 20 is operated automatically by a thermostat 27 or by hand to prevent the liquid running through and infecting the coolers 4, 5, 6. Milk when treated is supplied at 0-15‹ C. to the preheater 4 in which it is raised to 60‹ C. It leaves the heater 3 at 75-85‹ C. and is cooled in device 4 to about 35-40‹ C., in cocler 5, which is supplied with spring water, to about 11-18‹ C. and in cooler 6, which is supplied with cooled brine, to 2-4‹ C.
