Title: Process of and apparatus for separating gas mixtures containing higher-boiling impurities
IPC: F25J5/00
Filed: 1950-05-05
Abstract: 671,859. Air separation. LINDE AIR PRODUCTS CO. May 5, 1950 [May 20, 1949]. No. 11226/50. Class 8 (ii) A process for the low temperature separation of a gas mixture e.g., air containing higher boiling point impurities comprises cooling the air at a condensation pressure below 125 p.s.i. e.g., in reversible regenerators 10, 11, passing a first stream through ducts 15, 16, 17 to a chamber 18 where it is scrubbed free of residual impurities and passing the cleaned gas through a duct 22 to a rectification apparatus D e.g., the high pressure stage 23 thereof, passing a second stream of air cooled in the regenerators to a temperature higher than the first stream through ducts 60, 62, 57 to one or other of solid impurity removers e.g., filters 66, expanding with the production of external work e.g., at a turbine 54 and using a portion of the resulting cold together with that of a least the effluent nitrogen from the head of the low pressure column 29 to effect liquefaction of a portion of the cleaned first stream by traversing a coil 38, and using the remainder of the cold for cooling the incoming air. In the production of gaseous oxygen, impurity bearing liquid air from the scrubber 18 after traversing one or other of filters 20 is fed to the low pressure column 29 as reflux, and the major portion of the clean gas is led to the base of the column 23, the remainder being condensed in a chamber 45 and returned to the scrubber 18. Liquid oxygen from the base of the column 29 is vapourized in a chamber 43, and after traversing a coil 50, a duct 51 and the exchanger 11 under regeneration, is delivered by a valved duct 52. The filters 66 are charged with silica gel which also absorbs vapours, and if desired the air expanded and cooled by the turbine 54 traverses one or other of filters 71 before passing to the column 29. The said second stream may also comprise cleaned air from the scrubber 18 which after traversing a duct 55 is warmed by incoming air in ducts 63 whereupon it joins the gas in duct 57. Carbon dioxide deposited in ducts 63 and filters 20, 66, 71 is sublimed by reverse flow of warm gas. In a modified process for the production of liquid oxygen, which is trapped from the base of the low pressure column, a portion of the cleaned first stream leaving the scrubber is mixed with the second stream leaving the regenerator in such proportions that the resulting temperature provides high efficiency of refrigeration on turbine expansion after filtration.

Title: Improvements in and relating to protective devices for electric lamp regulators
IPC: H02J7/18
Filed: 1924-05-07
Abstract: 215,762. Dick, E. May 7, 1923, [Convention date]. Protective systems with fuses.-The movable contact 10 and resistance 9 of an automatic regulator for a train lighting installation, are automatically protected against excess current flowing through the resistance by the actuation of a relay 20 short-circuiting the resistance through contacts 19, 22 and a coil 17, this short circuit being interrupted after the excess current has vanished. The contact 10 is displaced automatically in accordance with the lamp voltage by a solenoid 11 connected in series with an adjustable resistance 12. A coil 16 of an electromagnet is connected as a shunt across the resistance 9, so that on the occurrence of excess current through the resistance 9, the electromagnet is energized sufficiently to attract the armature of the relay and close the short circuit 19. 22, 17, the excess current through the coil 17 maintaining the relay in its displaced position. Upon cessation of the excess current, for example, by the blowing of one of the fuses 15, a spring 21 returns the relav to its normal position. When the relay 20 is actuated, contacts 19, 23 are also closed, thereby short circuiting the solenoid 11 to allow the contact 10 to return to its normal position, alternatively this may be effected by interruption of the solenoid circuit. The coil 16 may be subdivided and connected to corresponding parts of the resistance 9 so that only portions of this coil are effective according to the position of the contact 9. Several coils in series with separate sections of the resistance 9 may be used in addition to or in place of the coil 16.

Title: Process and apparatus for carrying out an endothermic chemical reaction
IPC: B01J19/00
Filed: 1975-03-18
Abstract: 1469902 Controlling endothermic reactions FRIED KRUPP HUTTENWERKE AG 18 March 1975 [23 March 1974] 11299/75 Heading B1X [Also in Division F4] In the carrying out of an endothermic chemical reaction, a heated inert gas (e.g. nitrogen) is used as the heating-up medium passed alternately first through one and then through the other or others of regenerator chambers such as 1, 1', and the heat from the chamber or chambers not at the time being heated by the gas is used in the carrying out of the endothermic chemical reation; the inert gas flowing in a circuit 2 in which it receives its heat in a heat exchanger 3/4 forming part of the coolant circuit 5 for a heat source such as a nuclear reactor 6. The chemical reaction may be carried out in the regenerator chamber itself or, as in the form shown, in a reaction chamber 10 (or 10') connected by a passage 12 (or 12') with the regenerator chamber 1 (or 1'). In Fig. 2 reactant gases entering at 11 (or 11') are preheated in the regenerator chamber 1 (or 1') before passing to the reaction chamber 10 (or 10') into which solid, liquid or gaseous reactants are charged at 13 (or 13') and 14 (or 14') whilst consumed reactants and reaction products are discharged respectively at 15 (or 15') and 16 (or 16'). In a modification of Fig. 2, the inert gas heats up only the regenerator chamber 1 (or 1') and by-passes the reaction chamber 10 (or 10'). Gas purifiers 7 and 9 are included in the inert gas circuit 2 and may be used particularly in the event that the inert gas becomes contaminated e.g. during the change-over period. If more than two regenerators are utilized, at any one time one may be in the heating-up phase, another in the change-over phase, whilst others are in the heat utilization period for the chemical reaction.  Emergency heating means (e.g. electric or fossilized fuel) may be provided for heating- up the regenerator in the event that the original heat source cannot be maintained. The regenerator casing may be electrically heated to avoid condensation thereon. Gaseous, liquid, sublimating, vapourising or pulverized catalysts may be supplied to the reaction either continuously or periodically. Or, when appropriate, a catalyst can be applied to the regenerator lining or heat storing material.

IPC: A01K41/02
Filed: 1918-07-12
Abstract: 122,994. Jackson, W. J. Mellersh-, (Watson, H. L.). July 12, 1918. Hatching-appliances.-An incubator comprising a series of separate compartments, with a single automatically regulated heating system, is provided with independent thermostatically controlled ventilating means for each compartment whereby the temperature and humidity therein are automatically regulated. Means also are described for simultaneously or selectively turning the egg-supporting trays in the several compartments. The casing 1 is divided by longitudinal and transverse partitions 5, 6, 7 into separate compartments, the longitudinal partition 5, 6 being hollow and open at the lower end to admit air, moistened by a water trough 19, and passing through apertures 11, 12 to the compartments. A partition or baffle-plate 13 divides the air supply to the apertures 11, 12. Within each compartment a thermostat 17 actuates a damper 15 to regulate the ventilation and humidity according to the temperature. The heating system comprises a heater 20 with automatically controlled dampers to maintain a constant temperature, and water circulating pipes 21, 23 leading to and from pipes 22 passing across the top of each compartment over radiating plates 31. In the case of a double decked incubator, as shown, valves 32 are provided in the upper circulatory system in order to regulate it down to that of the lower system. The water in the upper and lower troughs 19 is heated by pipes 29 from a separate supply in the heater 20, the temperature being indicated by a thermometer 30. The arrangement counteracts excessive heating by increasing the ventilation, the humidity varying inversely with the rate of flow of the air over the troughs 19. The egg-supporting trays comprise upper and lower frames 34, 35 each provided with wire netting 36, as shown in Figs. 5 and 7. The trays fit between ledges 41, 42 in end supports 37, 38, rotatably mounted in the transverse partitions 7. The end supports a.re connected by spacing bars 39, and springs 43 in the upper ledges 41 grip the tray, serving together with stops 45 to prevent displacement. Gear-wheels 47 on the end supports 38 mesh with corresponding gears 50 on a common shaft 51 extending longitudinally through the casing and terminating in a crank-handle whereby the trays may be simultaneously rotated. The trays in any selected compartment may be left undisturbed by loosening the set-screw securing the corresponding gear 50 to the shaft.

Title: Intrusion detection apparatus having protection against jamming
IPC: G01S13/56
Filed: 1970-03-10
Abstract: 1308701 Intruder alarms JOHNSON SERVICE CO 10 March 1970 [10 March 1969] 11629/70 Heading G4N [Also in Division H4] A detection system comprises a microwave transmitter, a receiver and amplifier, an alarm responsive to signals of predetermined amplitude in a predetermined range of Doppler frequencies and means responsive to an amplifier output greater than said predetermined amplitude. In a system for detecting an intruder in a surveillance area, a transistor oscillator 1 feeds through a coaxial cavity 18 to a transmitting aerial 2. The oscillator frequency is controlled by a regulated D.C. bias or line 21, which is modulated by a free-running transistor multivibrator 8. Signals received at aerial 6 thus have a background component of the modulating frequency, e.g. 500 Hz, as well as the Doppler signals, e.g. 1-180 Hz due to moving objects in the surveillance area. The mixer 10 output passes through a low pass amplifier having # rapid roll-off above 180 Hz. The three parallel detector channels 12-14 are responsive to different kinds of signals. The motion alarm circuit 12 has a filter passing only the expected Doppler frequencies, followed by a Schmitt trigger which on reception of a Doppler signal of large enough amplitude, turns off transistor 24 which de-energizes coil 27 thus operating the alarm relay 17. Supervisory circuit 13 is receptive only to the modulation frequency of 500 Hz and integrates the signals to prevent operation of a second alarm. If the transmitter or receiver malfunction, the supervisory signal is lost and the second alarm is triggered. A signal at a frequency inside the roll-off portion of the amplifier 11 characteristic could saturate amplifier 11 without operating the motion alarm and thereby de-sensitise the apparatus to Doppler signals. Anti-jamming circuit 14includes a high part filler 30 producing with amplifier 11 an overall constant gain-with-frequency response. The filter output is detected by diode 35 and fed to the base of transistor 29. If the signal amplitude is high enough, the transistor will turn off thereby operating the alarm 17.
