Abstract: A storage-stable, lyophilized Minor Determinant Mixture (MDM) composition which can be reconstituted with water to yield a solution which is used to detect allergy or hypersensitivity to penicillins, comprising: benzylpenilloic acid; benzylpenicillin; benzylpenicilloic acid wherein at least about 94.5% of the benzylpenicilloic acid is the stereoisomer (5R,6R) - benzyl - D - penicilloic acid; an alkali metal salt; a pH-buffering substance; and a critically low amount of water. In the method of the invention, an aqueous solution of benzylpenilloic acid, an alkali metal salt, and a pH-buffering substance is prepared. The benzylpenilloic acid in this solution is neutralized with aqueous sodium hydroxide. While maintaining this solution at a temperature of from about 0°C to about 5°C, the following steps are performed: First, the benzylpenicillin and the benzylpenicilloic acid are dissolved into the solution. The benzylpenicilloic acid in the solution is neutralized with aqueous sodium hydroxide. Next, the pH of the solution is adjusted to a physiological pH. This solution is then sterile filtered. After performing these steps in which the solution was maintained at a temperature of from about 0°C to about 5°C, the solution is frozen in dehydrated containers. After freezing, the frozen solution is lyophilized.

Abstract: The invention relates to automatic phase adjustment in a phase locked loop including an oscillator (Os) with a controllable frequency. The oscillator generates a timing signal which is used together with a received data signal (1) to form two pulse trains (9,10) which comprise pulses of a duration which in the first pulse train (9) is independent of, and in the second pulse train (10) is responsive to, the phase position of the timing signal relative the phase position of the data signal. The pulse trains are utilized to form a control signal to the oscillator (Os). In forming the pulse trains (9,10), there is utilized a first array of signals (6-8) which are formed by the data signal (1) being sampled in several different phase positions with the aid of mutually phase shifted clock signals (2-4). A rapid locking-in of the phase locked loop is obtained in accordance with the following. The signals in the first array are sampled simultaneously with the aid of a common clock signal (11), whereby a second array of signals (12-14) is formed. The signals (12-14) in the second array are compared with each other and an error signal (15,16) is formed if there is deviation. The error signal is used to amplify the control signal to the oscillator (Os).

Abstract: In a mounting apparatus of the type wherein various vibrations over a wide frequency range are inputted, such as a mounting apparatus of a car engine, low kinetic spring characteristics for the input vibration of medium to high frequency ranges must be accomplished while securing high damping characteristics for the input vibrations of a low frequency range. In the present invention, a pressure receiving member (38) and a variable capacity balancing chamber (40) which communicate with each other through an. orifice passage (46), into which pre-determined non-compressible fluid is sealed, respectively, and to which vibrations are inputted, are disposed between first and second support members (10 and 14) connected flexibly with each other by a rubber elastic member (26). A moving member (54) is stored movably in the pressure receiving chamber (38) and support means is disposed in order to prevent adhesion of the moving member (54) to the inner surface of the pressure receiving chamber (38) to define a vibration operation portion having a predetermined gap where fluidization of a fluid is generated around the moving member (54) at the time of the input of vibrations. In the mounting apparatus of the present invention, a high damping effect on the input vibrations of the low frequency range is exhibited by the resonance action of the fluid fluidized inside the orifice passage (46) and the low kinetic spring effect can be exhibited on the input vibrations of the medium to high frequency ranges by the resonance action of the fluid fluidized in the vibration operation portion defined around the moving member (54).

Abstract: Disclosed is an intrafield interpolation circuit for interpolating pixel signals between pixel signals sampled based on Multiple Sub-nyquist Sampling Encoding (MUSE). There are provided in this interpolation circuit switches (S4a, S4b, S4c) for selecting pixel signals from delay elements (33h, 33i, 33j). Since these switches are controlled at a suitable timing, correct pixel signals obtained by an operation are interpolated between the sampled pixel signals. In addition, since pixel signals required only for an interpolation processing are handled, multipliers require half the operation speed of a conventional circuit, resulting in an enhanced reliability in operation.

Abstract: 1. Safety valve which is replaceable under internal tank pressure. 2.1 Safety valves protect tanks and pipelines against unacceptably high overpressure. The function of the safety valves must be tested at specific time intervals. If a safety valve which is replaceable under internal tank pressure is screwed out in conjunction with a closing valve, the tank has no safety valve during this replacement phase, that is to say it has no overpressure protection. 2.2 If the valve closing cone 6 is provided with an acoustic warning and signalling device 3 on the side facing away from the flow, that is to say on the pressure tank side, this device is triggered as soon as the safety valve is screwed out and thus provides a penetrating and continuous warning to reinsert a new safety valve. 2.3 Especially for liquid gas tanks with a propane-butane filling, this device is suitable for recurrent testing of the safety valve, without having to empty the pressure tank. <IMAGE>
