IPC: F24J2/48
Filed: 1985-12-17
Abstract: A solar collector comprising a thin conductive metal 
plate (13) having an ultra-thin coating film thereon, the plate 
being a blue colour which is selective to the solar spectrum 
in the range 475-495 nm and a solar heating system 
comprising such a plate. The invention also includes a solar 
heater having a collector plate (22) mounted in a receiver (24) 
in such a way as to define volumes thereabove and 
therebeneath, the volume thereabove having, as a wall 
opposite the collector plate, a sheet of glass or other 
thermally transmitting medium (23) and means (25, 26, 28, 
29) whereby fluid can enter and leave the receiver. The 
invention also includes an air heating system comprising a 
number of such solar heaters interconnected so that air can 
sequentially pass through the volumes defined by the 
collector plate (22) and the glass surface (23) and then 
through secondary channels beneath the collector plate.

Title: Cardiac valve prosthesis with valve flaps of biological tissues
IPC: A61F2/24
Filed: 1985-03-13
Abstract: A cardiac valve prosthesis (1) comrises an annular frame (2) through which blood can flow and a valve sleeve (11,12) of biological tissue with a plurality of valve flaps (14) which can be forced apart by the blood passing through the prosthesis (1) in one direction and which prevent the blood flow in the opposite direction, being brought into a mutually mating position under the pressure exerted by the blood itself. τheframe of the prosthesis includes a rigid or semi-rigid stent (2) constituted by a tubular body with a ring of apertures (5) and with first (2a) and second (2b) end edges which, in the implanted position of the prosthesis, are respectively upstream and downstream with respect to the direction of flow of the blood through the prosthesis. The tubular body also has integral axial appendages (4) each of which has respective apertures (6) adjacent its free edge. A covering of biocompatible textile (71, 72, 73) completely covers the rigid stent (2): the covering has associated suture stitches some (92, 93) of which extend through the apertures (5) of the said ring to attach the covering (7) to the stent (2) itself. The valve sleeve includes two sheets of biological tissue (11, 12) sutured (13) together and wound into a tube, the radially outermost one (11) having a shape which substantially reproduced the shape of the stent (2) of the frame and the radially innermost one (12) whereof, carrying the valve flaps (14), has a collar end portion (15) which can be turned outwardly of the frame (2, 7) at the first end edge (2a) of the stent (3) of the frame (2, 7). The valve sleeve is fixed to the frame by further suture stitches, some (10) of which extend through the apertures (16) in the ends of the appendages (4) of the frame stent. Other suture stitches (121) connect the end edge of the collar end portion (15) of the radially inner sheetto the covering of biocompatible textile.
Patent EP-0197501-A3 (EP)
IPC: H01L29/78
Filed: 1986-04-02
Abstract: Hot electron injection into the gate oxides of MOSFET 
devices imposes limitations on the miniaturization of such 
devices in VLSI circuits. A buried channel is provided to 
guard against hot electron trapping effects while preserving 
process and structure compatibility with micron or submic­
ron VLSI devices. The channel current is redirected into a 
buried channel at a distance away from the interface in the 
vicinity of the drain region where the hot electron effect is 
most likely to occur. This redirection is effected by providing 
a buried, lightly doped region extending inwardly from the 
conventional source and drain implant profile regions.

erkannt, daß sich die Auswirkungen der Substantivität der 
Ausrüstungsmittel auf die Gleichmäßigkeit der Ausrüstung 
ausschalten lassen, wenn im Zuge der Applikationsoperation 
das Tauchen des Behandlungsgutes in der Flotte des Ausrü­

Title: Three-dimensional visual screening system
IPC: H04N13/122
Filed: 1987-09-25
Abstract: A binocular stereoscopic x-ray inspection system is 
provided in which the objects to be inspected pass successively 
under two x-ray beams, and over two respective line-array 
detectors upon which the beams fall, the two beams being set at 
an angle to one another in the plane parallel to the path of

each object on the line-scan principle. Those views are stored 
in respective frame stores, the video information from which is 
employed to create a composite image on a monitor that can be 
viewed as an apparently three-dimensional image. The technique 
is not limited to x-rays, nor to objects that travel nor to 
rectilinear movement but instead the relative movement could be 
achieved, for instance, by mounting two line sensor cameras on 
a rotating head.

Title: Heat seal temperature control
IPC: B65B51/30
Filed: 1988-03-17
Abstract: Method and circuitry is disclosed for controlling and stabilizing temperature of a resistance heat sealing element used in packaging operations. Temperature of the heat sealing element is measured by monitoring its resistance by means of a current sensing resistor placed in series with the heat sealing element. The resistivity of the heat sealing element is a function of temperature and current measurement, assuming substantially constant applied voltage, is an accurate measure of sealing element temperature. The circuitry reduces application of electric power to the sealing element in response to current in the sealing element dropping below a predetermined level. The circuit either continues application of electric power, or increases it, in response to the current being above the predetermined level. Circuitry is also provided for compensating for undesirable line voltage changes to maintain the heating element at a constant temperature. Means is provided for adjusting the predetermined temperature at which power cut off occurs. The circuit and sealing element can be operated in either a continuous manner of in a "one-shot" fashion which has been determined as particularly useful for making seals which bear embossed indicia.
