Abstract: 1,107,587. Determining gas absorption by a liquid. C. A. BROWN. 20 July, 1965 [20 July, 1964], No. 30899/65. Heading B1X. The gas consumption by a liquid substance is determined by filling a closed system with the gas, e.g. hydrogen, introducing the liquid substance into a vessal within the closed system, permitting absorption to take place, introducing a displacing liquid, e.g. water, into the system to restore the pressure to its previous level before the introduction of the liquid substance, and determining the gas absorbed from the volume of displacing liquid added. A catalyst is added prior to filling the system with gas to facilitate absorption, the gas being generated in an bowl 26 and purging the system of all other gases. After purging a plug 94 effects a seal and the level of mercury 92 in tube 86 indicates the starting pressure. The unsaturated liquid substance is the injected through rubber stopper 30 and hydrogenation takes place, helped by magnetic stirrer 14, and with the entire system immersed in a bath 112. At the termination of hydrogenation, when pressure has decreased and the level of mercury has therefore risen in portion 86, water is forced into the system through hollow needle 80 by a burette 66, mercury 82 acting as an immisible sealing liquid. When the mercury level in portion 86 has dropped to its starting level the amount of water added is measured and the volume of gas absorbed may be calculated from the measurement.

Abstract: 758,503. Punching. KELSEY-HAYES WHEEL CO. Oct. 28, 1954 [Nov. 30, 1953], No. 31196/54. Class 83 (4). [Also in Group XXX] In a machine for punching tyre-carrying wheel rims to form holes, e.g. to receive the tyre valves, the movement of successive rims between guides to and from the punching device is automatically controlled. Each rim is guided down an inclined table 2 by bars 4, one of which is laterally adjustable, until it engages a stop 29 carried on one end of a lever 28 the other end of which carries a stop 30. As the rim approaches the punching device 5 it engages a pivoted rail 49 to actuate a switch 42 and when in the correct punching position determined by the stop 29 it actuates a switch 41 (not shown). The latter which causes liquid to be supplied to one end of a cylinder 18 mounted on a U-shaped member 7 carrying the punch 8 to move a piston 20 carrying the die 10. The member 7 is slidably mounted in a bracket 6 angularly and laterally adjustable relative to the table 2 and is urged against an adjustable stop 16 by a spring 12. The piston 18 moves the die 10 up to the wheel rim and the punch 8 then moves down to punch the hole. At the end of its travel the member 7 momentarily actuates a switch 43 whereupon compressed air is supplied to a cylinder 36 to rock the lever 28 which lowers the stop 29 to free the punched wheel rim and raises the stop 30 to prevent movement of the following rims. When the punched rim has slid off the table 2 and the switches 41 and 42 have opened, the lever 28 is returned to its normal position so that the next wheel rim slides down to be punched.

Title: Monitoring circuit
Inventor: SVANSSON ARNE LENNART
IPC: G01T7/12
Filed: 1967-07-06
Abstract: 1,141,730. Threshold circuits. ATOM-ENERGI A.B. 6 July, 1967, No. 31250/67. Heading H3T. [Also in Division G1] A circuit for detecting when the amplitude of a signal has exceeded a predetermined level for an appreciable time (e.g. for monitoring the neutron flux in a reactor) comprises switching means 2 connecting the neutron detector 1 to an amplifier 3 and two-state circuit 4, the output of the latter operating the switch 2 and a further two-state circuit 5 which is coupled to an output circuit 6 and alarm 7. Under normal conditions a signal is produced from a radioactive source in the detector 1 and amplified by 3 to a level which is insufficient to make a Zener diode 47 conduct. Transistor 48 is therefore non-conducting and transistor 54 is conducting. If the neutron level rises above a predetermined value, material in the detector is converted into a short-lived isotope (¢-life 1 minute) which emits beta rays and increases the signal from the detector 1. Transistor 48 then conducts and relay 23 operates to disconnect the amplifier from the detector at contacts 21. Transistors 48 and 54 are therefore cut off, and at the same time, capacitors 64a and 64b are charged through contact 22. The cutting off of transistor 48 de-energizes the relay and the signal from the detector is re-applied to the amplifier 3. If the signal has dropped to its former level no further action occurs, but if the signal is still at its high level transistor 48 will conduct again. However, the charge on capacitor 46 will prevent the relay from operating and transistors 4 and 5 will be held in a conducting state, maintaining transistors 62a and 62b conductive. The charge on capacitors 64a and 64b (duplicated for reliability) will then cause the alarm 7 to operate. Thus a double operation of circuit 4 is necessary to give the alarm. The duration of the high signal needed to operate the alarm depends on the time-constant of the CR circuit 45/46, e.g. 3-4 seconds, this being about twice the time taken for the sequence of circuit changes. The relay 23 may be replaced by an electronic switch and tubes may be used instead of transistors. The circuit may be tested by feeding pulses from a generator 85 to the amplifier 3 and measuring the power consumption in a unit 86 which gives a different alarm.
