Title: Temperature compensating system
IPC: G05D23/24
Filed: 1964-03-26
Abstract: 1,015,239. Electric correspondence control systems. BAUSCH & LOMB Inc. March 26, 1964 [April 1, 1963], No. 13058/64. Heading G1N Minor variations in temperature inside a temperature controlled chemical reaction chamber are sensed by a thermistor and used for automatic modification of the reaction time. As shown (Fig. 1), the temperature inside a reaction chamber 1 is controlled by a closed loop system comprising a heater 3 and thermostat 4. A sample 7 to be subjected to the conditions inside the chamber is carried into and out of the chamber as a conveyer belt 5 driven by a motor 6 which is energized for this purpose for two short periods via contacts 26, 27, 28, determined by cams 22, 23 driven by a synchronous motor 20 energized by an oscillator 18 whose frequency is determined by the actual temperature inside the chamber, as sensed by a thermistor 9. The latter is connected in a resistance bridge 10 whose amplified unbalance voltage determines the frequency of oscillator 18. Thus the time sample 7 stays inside the reaction chamber 3 is inversely proportional to the temperature in the chamber. The reaction changes in the sample may be sensed by measuring its opacity, using a lamp and photocell (not shown).

Title: Improvements in or relating to valve operating mechanism for water gas plants
IPC: C10J3/24
Filed: 1927-05-16
Abstract: 283,909. Lowe, J. Jan, 20, 1927, [Convention date]. Water gas and producer gas plant.-In plant for making water gas and producer gas and comprising twin generators each used alternately for making these gases, such as described in Specification 149,928, the various valves are interconnected by linkwork and actuated automatically by hydraulic means. A valve Q controls the passage of fluid through a pipe IV, Fig. 3, leading both to cylinders H, H<1> actuating the water gas outlet dampers G and producer gas dampers E, and to cylinders H<2>, H<3> actuating the steam supply valves C. To cause a scavenging action to sweep the producer gas from the generator into the producer gas flue so that it is not carried forward into the water gas flue, the piston I of the cylinders H, H<1> has a delayed action so that it moves slowly during the mid position of its stroke. The piston rod carries a cross head J connected to the damper rods of two diagonally opposite dampers G and E on the two generators. The rods K attached to the four dampers G, E are connected to swinging levers M, and the coupling rods N for the blast valves B are connected to swinging levers M<1>. When the valve Q is opened, the cylinders H<1>, H<3> actuate the valves G, E, B and valve C respectively, but owing to the fluid outlet from cylinder H being restricted by a valve II when the middle portion of the stroke is reached, the motion of the valves is slowed up, and, the blast valves B being closed and one of the steam valves C open, the gases in the generator previously blasted up are swept into the producer gas flue D because the resistance in this flue is less than that in the water gas flue F. The rods N actuate the valves B through a lost motion device so that the blast valves are rapidly changed over at the beginning and end of the blasting period. Specification 223,313, [Class 135, Valves &c.], also is referred to.

[Also in Division F4] The top of a mine shaft is sealed by a valve member 5 and as the cage 10 rises and before it lifts the member 5 flexible curtains 13 slide in arcuate guides 14 and close off the shaft beneath the cage thereby preventing escape of the air in the shaft. As the cage rises, a member 11 thereon contacts a counterweight 7 and raises it relative to the member 5. This upward movement of counterweight 7 allows, by means of cables 12 and pulleys 15, the curtains to be lowered along their guides. Further raising of the cage causes member 11 to lift the member 5 until the cage reaches ground level 2. In addition, doors 3 permit access to the cage at the level of landing 4.
