Title: Improvements relating to telegraph apparatus
IPC: H04L1/08
Filed: 1932-11-23
Abstract: 397,725. Wireless signalling. HULSEWE, A. F., 188, Keizersgracht, Amsterdam. Nov. 23, 1932, No. 33132. [Class 40 (v).] Relates to systems in which telegraph signals are repeated or transmitted simultaneously over a plurality of channels to produce a plurality of perforated tapes which together will give a record free from the effects of atmospherics &c. and comprises an editing device to deal with Morse tapes in such a system. In the embodiment described, three records on Morse tapes are passed simultaneously through Wheatstone transmitters, the transmitting levers 1, 2, 3, Fig. 2, of which either make contact with the space-contacts 4, 5, 6 or marking contacts 7, 8, 9 respectively. A relay 10 receives a negative marking impulse from battery 11 when the levers 1, 2, 3 are all engaging the marking contacts 7, 8, 9. When one or more of the levers 1, 2, 3 is on the spacing contacts 4, 5, 6, the relay 10 receives a positive spacing impulse. Thus only when a signal appears on all three tape records simultaneously does the relay 10 record it. Either set of contacts may be switched out of circuit when working with marking or spacing impulses only. In a modification, Fig. 3, the levers 1, 2, 3 are arranged in parallel and co-operate with a single contact 12, 13 or 14 respectively, during spacing intervals to short-circuit the relay 10. Only when marking signals occur on each tape simultaneously is the short-circuit removed from relay 10 to allow it to be energized. A special signal may precede the message signals to indicate the commencement of the latter on each tape.

Nov. 23, 1932, No. 33135. Convention date, Nov. 24, 1931. [Class 29.] In a system for the supply of lubricating or fuel oil or other liquid, the liquid is fed by a pump 10 to a chamber 12 having two outlets 13, 14 controlled by oppositely - acting valves 23, 24 and connected through a cooler or heater 18 and a byepass 15 resspectively to the supply line 16, the valves being operated electrically under the control of a viscosity gauge 31 connected to the pipe 16 in such a way that the viscosity of the liquid in the line 16 is maintained substantially uniform. The sum of the effective areas of the two outlets is constant for all positions of the valves. The latter are connected to the ends of a centrally-pivoted lever 22 actuated by a rod 26 forming the armature of a solenoid 25. A spring 28 normally closes the valve 24 and opens the valve 23 to an extent determined by a wheel 29 adjustably threaded on the end of the rod 26. When the index finger 35 of the gauge overlies a manuallyadjustable finger 36 set to the desired viscosity, a circuit 37 is completed and the solenoid is energised so as to open valve 24 and close valve 23. Alternatively, the valves may control the outlets from the cooler or heater and the byepass.

A process for the reduction of iron ores comprises effecting reduction-chlorination at an elevated temperature in the presence of a carbonaceous reducing agent to produce gaseous chlorides of iron and some gangue materials, effecting oxidation-chlorination in the absence of any reducing agent with the production of solid oxides of most of the gangue materials and additional ferric chloride, separating the gas from the other substances, condensing ferric chloride from the gas, and recovering the ferric chloride. As shown, ore and chlorine gas pass in counter-current through at least two chambers, which may be cyclones, one containing fresh ore -the oxidation-chlorination chamber-and the other the waste ore from the first to which coke has been added-the reduction-chlorination chamber. The ferric chloride may be oxidised to produce iron oxide and chlorine, the latter being recycled and the former reduced to iron, e.g. by means of hydrogen which may be obtained from the electrolysis of salt used to produce chlorine for the process.

Title: Improvements in a process and apparatus for the production of salts from brines and solutions
IPC: C01D3/06
Filed: 1927-12-28
Abstract: 308,746. Dehn, F. B., (Martin-Colvin Co.). Dec. 28, 1927. Spray evaporators; separate heater and evaporator apparatus.-In the recovery of salt from salt solutions used in cooling exhaust steam from turbines &c. by spraying the brine into the atmosphere to form a mist above a pond containing the solution, the temperature of the mist is maintained above the dew point of the atmosphere by controlling the amount of air coming into contact with the mist, e.g. by providing shuttered frames round the sides of the pond. Exhaust steam from a turbine 10 is cooled in a condenser 12 by circulating therethrough brine from tanks or ponds 26, 29 which may be employed together or separately. The ponds are surrounded by frames 90 carrying shutters 91 operated by rods 92 so as to control access of air to the mist above the tanks. The heated brine is sprayed into the tank 26 through a manifold 22 the diameter of which is gradually reduced towards its outer free ends to equalize the pressures in the spray arms 24. A similar manifold 28 is provided over the tank 29. The cooled brine in the tanks is re- - turned to the condenser by a pump 48 through valve-controlled pipes 34, 35. The pipe 34, Fig. 3, has a check valve 39 which prevents return of liquid to the tank and terminates at the wall 42 of the tank adjacent the open end 43 of a pipe 44 which in turn is joined to a pipe 64 running along the bottom of the tank and provided with a slit 67 through which the brine is sucked drawn by the suction in the pipe 34. The concentration of the solution may be changed by admitting fresh brine or water through pipes 52, 50, respectively. The tank 26, Fig. 2, is formed with sloping slides 68, 82 and a channel 63 which is extended upwardly through the side wall 68 to form a. housing for a travelling carrier 73 which removes the crystals. The bottom of the tank is formed with a number of parallel grooves 63 separated by walls 80 and containing endless bands with projecting fins for collecting the crystals on the carrier 73. Frames 95 having adjustable 96 control the fall of the spray from the nozzles 23. Specification 195,675 is referred to.

Title: Improved heat pump
IPC: F24D11/02
Filed: 1963-09-06
Abstract: 1,032,729. Heat pumps; ventilation. W. F. CAREY. Dec. 7, 1964 [Sept. 6, 1963], No. 35217/63. Headings F4H and F4V. Heat is recovered from the wall cavities of buildings by passing air through the cavities and over the evaporator of a heat pump, the external wall of the cavity being thermally insulated. As shown, air from the loft 8 of a building 1 is drawn downwardly through cavities 6 in walls 9 by a fan (not shown) and passed over the evaporator 3 of the heat pump, the air being then returned to the loft to complete a substantially closed heat recovery cycle. The condenser 2 of the heat pump heats air circulating in a substantially closed ventilating cycle, part of the air in the latter cycle being tapped off downstream of the condenser and supplied to the heat recovery cycle. An equivalent amount of fresh air is admitted to the ventilating cycle and the same amount of air is vented from the heat recovery cycle to maintain the volume of air in that cycle constant. Frost-free operation of the evaporator is assured by the above system at all but extremely low ambient temperatures, and under the latter conditions the evaporator is provided with an auxiliary heater, e.g. the exhaust of a diesel engine used to drive the compressor, the coolant for said engine, hot water from a stove or coal fire, an electric heater or a gas burner.
