Abstract: The present invention is a flash steam generator to be used as an integral component of a steam sterilizer. The generator comprises a metal block (11) having a first bore (12) drilled lengthwise through the metal block. Surrounding the first bore is a plurality of additional heater bores (14) in which heating elements (15) a re inserted. The generator is integral to the sterilizer piping and control systems. Wate r is supplied to the first bore (12) by the sterilizer piping system, and electricity is supplied to the heating elements by the sterilizer power supply. The heating elements (15) convert the electricity to heat, which transfers via the metal block (11) to the first bore (12) where the heat rapidly boils the water contained therein in what is essentially a flas h vaporization process. An overtemperature device protects the system should the heaters be energized without sufficient water in the block. A safety valve exists between the blo ck and the sterilizer chamber to protect the block and the chamber from overpressure conditions. The block and piping are properly insulated to prevent heat loss to the atmosphere and injury to persons operating the sterilizer.

Abstract: A radio transceiver system uses a single variable local oscillator frequency source which is used in mixing both before and after a band-pass filter.  This causes a reduction in band-pass filter bandwidths.  In an all-band transceiver for PCS for example the effect of this reduced bandwidth requirement is to increase the spacing between the transmit bands and the receive bands and thereby enable a reduction in transmission noise interfering with the reception bands.

Abstract: Sliding gate valve (10) for a vessel containing molten metal has a housing (12) and a lid (15), which is pivotally mounted on it and receives a refractory valve plate (22) which may be pressed by clamping elements against a refractory sliding plate (23) in sliding contact with this valve plate (22). This lid (15) is locked by a locking means (20) in the direction of sliding of the reciprocable sliding plate (23), the locking means (20) being so constructed that, when the position of the lid (15) changes in the direction of sliding of the sliding plate (23), it automatically relocks and that the locking means (20), however, permits the movement of the lid perpendicular to the direction of sliding. The lid (15), which receives the upper valve plate (22) is pivotally mounted on the housing (12) and the clamping elements are arranged particularly in pairs on both sides of the lid (15) and are constructed as pivotable clamping bolts (33) on the housing (12). An operationally reliable and constructionally simply sliding gate valve is thus provided.

Abstract: The invention is related to a method and an apparatus for sorting seeds for the assessment of the maturity and quality of seeds by measuring the amount of chlorophyll fluorescence. The method is based on measuring the amount of chlorophyll fluorescence of the seed envelope and of tissue containing chlorophyll becoming visible when cracks in the seed envelope are present. The invention consists of inducing fluorescence of the chlorophyll molecule by irradiating the seeds with electromagnetic radiation with a suitable wavelength and measuring the chlorophyll fluorescence. Properties of the method are the very high sensitivity, being fully non-destructive and the very high speed. These characteristics of the invention make it possible to construct a sorting device by which seeds can be selected on basis of the amount of chlorophyll. Because the intensity of chlorophyll fluorescence is directly related to the maturity and the presence of cracks in the seed envelope, and therefore the quality of the seed, it is now possible to sort seeds on their quality. Experiments are being described of seeds from white cabbage, sugarbeet, carrot, pepper and tomato.

Abstract: The present invention relates to a wheel grid assembly and vehicle towing apparatus.      The wheel grid assembly includes a wheel boom (26) and a pair of lift arms (31). Each lift arm consists of an extension arm segment (32) and an engaging arm segment (33) pivotally mounted to the extension arm segment. Each engaging arm segment consists of an actuating arm segment (35) and a gripping arm segment (34) extending in opposite directions from the pivot point. A pair of linear actuators (41) rotate the engaging arm segments about their pivot points to engage the wheels of a vehicle to be towed. Each linear actuator is attached to a respective engaging arm segment through an over-center locking mechanism (40). The over-center locking mechanisms lock the engaging arm segments in wheel engaging positions without aid of force from the linear actuators. The wheel grid assembly of the present invention may be incorporated with an extensible main boom (21), and utilized with various configurations of tow vehicles.

Abstract: Un cathéter permet d'introduire des électrodes dans une veine pour un traitement de l'insuffisance veineuse, avec effraction minimale, par l'application d'énergie pour le chauffage sélectif d'une veine. On positionne le cathéter à l'intérieur de la veine à traiter, et les électrodes placées sur la cathéter sont déplacées vers un côté de la veine. On applique de l'énergie radiofréquence de manière directionnelle à partir des électrodes, au niveau de l'extrémité fonctionnelle du cathéter pour provoquer le chauffage localisé et le retrait correspondant du tissu veineux adjacent, dont les commissures, les valves et les orifices de la veine. On peut utiliser la fluoroscopie ou les ultrasons pour détecter le retrait de la veine. Après avoir traité une section de la veine, on peut repositionner le cathéter pour placer les électrodes et traiter d'autres sections de la veines jusqu'à ce que toutes les valves veineuses voulues aient été réparées et rendues opérationnelles sur le plan fonctionnel.
