Title: Improvement in a method of preparing sterilised durable medicinal solutions in hermetically sealed containers, particularly in ampoules
IPC: A61K9/00
Filed: 1951-06-28
Abstract: Sterilized durable medicinal solutions in hermetically sealed vessels, particularly ampoules, are degassed and prepared by applying a vacuum to the solution, subjecting the solution while still under vacuum to oscillations of a frequency between 15 and 60 KHz, so that no chemical reactions take place, saturating the solution with an inert gas such as nitrogen, sealing the vessel or ampoules, and heating the sealed vessels containing the solution to sterilizing temperature.  Preferably the solution is repeatedly subjected to vacuum and said oscillations before being sealed in the vessel.  The oscillations may be produced by a magnetostrictive transmitter or by a quartz crystal the emitted energy being up to 2 kW, the emitted energy preferably passing through a bath of liquid such as water or kerosene directly on to the vessel which contains the solution to be treated.  Examples relate to the degassing of solutions of morphinum hydrochloricum, adrenalin, and vitamin E dissolved in olive oil. After being degassed these solutions can be sterilized at temperatures of 110 to 115 DEG C. during a period of 15 minutes.ALSO:Sterilzed durable medicinal solutions free from dissolved carbon dioxide and oxygen in hermetically sealed vessels, particularly ampoules, are prepared by applying a vacuum to the solution, subjecting the solution while still under vacuum to oscillations of a frequency between 15 and 60 KHz, so that no chemical reactions take place, saturating the solution with an inert gas such as nitrogen, sealing the vessel or ampoules, and heating the sealed vessels containing the solution to sterilizing temperature.

Title: Multivibrators Employing Transistors of Opposite Conductivity Types
IPC: H03K3/353
Filed: 1967-04-06
Abstract: 1,172,000. Transistor multivibrators. RADIO CORPORATION OF AMERICA. 6 April, 1967 [15 April, 1966], No. 15848/67. Heading H3T. In a multivibrator, having first and second transistors 10 and 12 of one conductivity type, a third transistor 14 of the opposite conductivity type connected in series with the first transistor 10 and a resistive means 20, and a fourth transistor 16 of the opposite conductivity type connetted in series with the second transistor 12, the output of the second transistor is connected to the control means of a fifth transistor 18 of the opposite conductivity type which has its conduction path connected across the resistive means 20, and the control means or the second and fourth transistors are connected together and to the output of the first transistor. In the monostable circuit shown, the resistive means 20 is an insulated gate field effect transistor, as are the other transistors of the circuit, and by controlling the conduction of the transistor 20, the period of the unstable state of the circuit may be varied. Alternatively, a resistor may be used in place of the transistor 20. Assuming the input 32 is O then transistors 10 and 16 are OFF and 12, 14 and 18 are ON, the output is O and the interelectrode capacitance of the transistors plus any required external capacitance 36 is charged to +V. When the input 32 becomes +V transistor 14 turns OFF and transistor 10 turns ON to discharge the capacitance 36; this turns transistors 12 and 18 OFF and transistor 16 ON, making the output +V. The circuit stays in this state until the input pulse ends when transistor 10 turns OFF and transistor 14 turns ON to allow the capacitor 36 to charge via the resistor or transistor 20 until the transistors 12 and 18 turn ON and the transistor 16 turns OFF to rapidly charge the capacitor 36. By including two transistors (44 and 46) in the input to transistors 10 and 14 (Fig. 4, not shown), which are controlled by the output voltage of the circuit, the unstable period begins when the pulse is applied instead of at the end of the input pulse as above. In an astable circuit (Fig. 5) a series connection of transistors 50, 52, 54 and 56, similar to 10, 14, 18 and 20, has its electrodes corresponding to the gates of the transistors 10 and 14 connected to the output B, the electrode corresponding to the gate of the transistor 18 connected to the point A and the input to the transistors 10 and 14 connected to the corresponding output point A of the series connection. By controlling the conduction of two of the transistors 20 and 54, both unstable periods may be varied. The circuits may be formed as integrated units.
