Abstract: 1. A process for the frequency stabilisation of a high-frequency free-swinging oscillator, in particular of the micro-wave oscillator in the transmitting branch of a transmitting-receiving device for a radio system modulated in analogue or digital fashion, wherein in the stabilisation circuit a digital frequency modulation is simultaneously effected in such a manner that part of the output signal of the free-swinging oscillator (20) to be stabilised is transmitted onto a programmable frequency divider (2) which has an adjustable dividing factor (x) and whose output signal of the divided frequency (fo /x, fZF /x), which corresponds to the digital frequency fluctuation of the frequency modulation, is compared with the stable referency (fR1 ) of a reference source (17) in a phase comparison circuit (23) and the resultant regulating voltage adjusts the frequency of the free-swinging oscillator (20) to a value which corresponds to the dividing factor and has the frequency stability of the reference source (17), characterised in that the output-coupled portion of the output power of the free-swinging oscillator (20) to be stabilised is mixed in a mixer (19) with the multiplied signal of a fundamental wave oscillator (16) which is stabilised with the aid of a reference frequency (fR2 ) of a further reference source (15) and the high-frequency output signal of the mixer (19) is fed to the programmable divider (2), whose frequency divided signal is compared with the reference frequency source (17) in the phase comparison circuit (23), which reference frequency source is designed so as to be adjustable in such a manner that the signal frequency of the reference source (17) is divided by a specific factor (q) in a programmable frequency divider (7) and compared with the reference signal (fR2 ) of the further reference source (15) of the readjusting circuit of the fundamental wave oscillator (16), which reference signal is frequency-divided by a fixed factor (s) in a second phase comparison circuit (8), and that in order to adjust the frequency of the fundamental wave oscillator (16) a portion of its output signal is fed to a further phase comparison circuit (11) by means of a programmable frequency divider (12) (dividing factor p) and compared with the divided frequency of the reference signal (fR2 ) of the further reference source (15).

Abstract: Device for moving an element between two end positions and for selectively holding this element alternately in one of these positions, comprising an energy buffer mechanically coupled with this element, which buffer may be in one of two corresponding stationary end states, in which the energy is present in the form of potential energy, and in intermediate translation states, in which potential energy is transformed in kinetic energy and vice versa, a mass driven by the energy buffer and moved to one of the two end positions, and locking means for each of the two end states of the energy buffer. According to the present invention the mass is movable elastically over a predetermined distance with respect to the energy buffer and with respect to the element, so that when the element reaches one of its end positions the mass can move further over a predetermined distance towards its end position, thus transforming all kinetic in potential energy. Preferably the energy buffer is a helical spring, housed in a cylindrical mass. Each spring end is received in a spring support, which rests upon an inward end flange of the mass. Each spring support may cooperate with a stationary stop, mounted on the housing wall, which stop can enter the mass through an opening in the said flanges, to arrest the spring supports. The movable element may be formed by one of these spring supports, and may operate the movable switch contact of an electrical switch.

The process involves sterilisation of a continuous sheet of material - caused subsequently to assume tubular format - by means basically of its being bathed on both sides and then sprayed with superheated steam, this likewise being jetted at either side. Following the heat treatment, the sheet is shaped into a continuous tube and filled, this dual operation coming about within an enclosure maintained in sterile conditions. Plant for carrying the process into effect basically comprises a first chamber (3) inside which the bathed sheet (1) is sprayed with steam, and second chamber (5) inside which sterile conditions obtain, wherein the sheet is duly shaped into a tube (10) and filled. The first chamber entry-point is by way of a siphon trap (8), and the first and second chambers are pressurised to a given level and equalised thus during operation of the plant.

Granted: 1991-09-18
Abstract: A blood glucose testing device includes an apparatus for forming a blood droplet of a controlled, generally uniform size from a finger which has been pricked to draw blood. The apparatus includes a "funnel" member providing an upper edge across which the finger is drawn to deposit blood on a surface down which the blood flows under the influence of gravity to a lower edge terminating at a point. The blood flows toward the point, forms into the droplet at the point, and, owing to gravity and the surface tension of the blood forms into the substantially uniformly sized droplet which falls onto a test strip positioned beneath the point. The device also includes a generator for generating audible signals indicating that a reaction to determine glucose concentration of the droplet has begun, and that the reaction should be terminated. The device includes a speech generator for announcing the glucose concentration.

Abstract: A process for producing an aerosol stream, which is conducted through an essentially aerosol-free vapor and/or gas stream to prevent undesirable precipitation of particles contained in the aerosol stream, is augmented by additionally employing thermophoresis. For this purpose, the vapor and/or gas stream is heated to a temperature which is higher than the temperature of the aerosol stream. Thermophoresis then causes the particles to be held within the aerosol stream.
