Title: Unite de production d'oxygene a l'etat gazeux
IPC: F25J3/04
Filed: 1986-08-08
Granted: 1991-03-13
Abstract: Unité de production d'oxygène à l'état gazeux de très grande pureté par refroidissement à très basse température de l'air. L'objet de la présente invention est la réalisation d'une unité de production d'oxygène à l'état gazeux ne nécessitant pas de turbine d'expansion, composant coûteux et souvent à l'origine de pannes. Dans l'unité ci-décrite, un organe de stockage d'oxygène liquide (23) est relié via un passage d'introduction (23a) à une partie supérieure (15) d'un rectificateur (11) qui consiste en la partie supérieure (15) pourvue d'un condenseur (16) et en une partie inférieure (12) à une pression intermédiaire, ce qui permet de refroidir le condenseur (13) avec l'oxygène liquide. L'air comprimé à une température extrêmement basse est introduit dans la partie inférieure (12) à une pression intermédiaire du rectificateur (11) via un organe compresseur d'air (1), une colonne de refroidissement d'air (6), une colonne d'adsorption (7) et un organe échangeur de chaleur (8), et ensuite refroidi avec la chaleur latente de vaporisation d'un azote liquide de reflux obtenu dans le condenseur (13) pour convertir l'air résultant en air liquide possédant une teneur en oxygène plus élevée. Cet air liquide est introduit dans la partie supérieure (15), et l'azote est extrait sous forme de gaz à une pression intermédiaire depuis le sommet de la partie supérieure (15), l'oxygène étant laissé à l'intérieur à l'état liquide en utilisant la différence entre les points d'ébullition des deux substances. L'oxygène gazéifié obtenu à partir de l'oxygène liquide restant est utilisé sous forme d'oxygène à l'état gazeux.

Abstract: A device for manufacturing molded articles of plastics material which have an outer skin of a plastics material free of expanding agents and a porous core of a plastics material containing an expanding agent includes an extruder head with a main duct in communication with a discharge opening. Two feed ducts for the two plastics materials lead angularly offset into the main duct at locations axially spaced from the discharge opening and from each other. A closing needle is axially movably placed in the main duct. The two feed ducts can be separated from the main duct by means of the closing needle. The closing needle defines a connecting duct extending essentially in axial direction. The connecting duct ends at the end face of the closing needle and at the circumference of the closing needle radially toward the more remote feed duct. In the closed axial position of the closing needle and in an at least partially open axial position of the closing needle, the radial circumferential opening of the connecting duct is located approximately on the same level as the inner radial outlet opening of the more remote feed duct. The closing needle is rotatable about the longitudinal axis of the extruder head relative to the outlet opening in any axial position of the closing needle.

Abstract: A video distribution system (e.g., CATV or MATV) employs at least one channel having a reception-defeating jamming signal which changes frequency periodically or, preferably, randomly. The signal originating head end distributes information characterizing the operative frequency of the jamming wave. At controller apparatus for authorized viewers, the jamming frequency specifying data is employed on a frequency agile basis to heterodyne the protected channel into a proper (fixed) frequency relationship with a notch band suppression filter to remove the jamming signal. The secure channel with the jamming wave removed is then again shifted to its original or other intended frequency to permit normal reception either directly by a standared television receiver, or via a frequency converter.

Abstract: A convection cooling vessel for materials exhibiting surfaces in arrangements with interspaces which can be flowed through, in particular of block charges made of light metal semifinished products, has a fan which delivers into an exhaust duct and on the suction side of which a forked pipe is arranged; on each leg of the forked pipe, there is a shut-off and control valve. Provided symmetrically in relation to the material are inflow ducts which are assigned to the legs of the forked pipe. Each inflow duct has a further shut-off and control valve. The shut-off and control valves in the forked pipe and in the inflow ducts can be adjusted in such a manner that, because of the suction effect of the fan, the material can be flowed through in the main flow or in the part flow and the flow direction of the cooling medium can be reversed. <IMAGE>

Title: Composite glass plate to cover buildings
IPC: E04F13/14
Filed: 1989-05-09
Granted: 1992-04-22
Abstract: There is a composite glass plate for covering buildings, in which a face-side, thicker pane (1) of glass is bonded over the entire surface to a rear-side, thinner layer (3) by means of a thermoplastic adhesive film (2). In this case, it is desired for the rear-side layer to improve the fire protection properties in a simple manner, to guarantee non-transparency and to allow special colour shades on the face side. This is achieved in that the rear-side layer is formed by a metal plate (3), the thickness of which is </= 0.4 times that of the pane 1 of glass and the thermal expansion of which differs from that of the pane (1) of glass by a maximum of 3 x 10<-6> k<-1>. The limitation of the thickness of the metal plate results in a usable overall weight and the coordination of the thermal expansion avoids temperature-related curvatures of the composite glass plate. <IMAGE>

IPC: H04W72/08
Filed: 1989-12-19
Granted: 1995-02-22
Abstract: A method of establishing a digital time-division duplex radio communication link between one of a plurality of portable units and a base unit in a cordless telephone system. Transmissions from the base unit are allowed only on a ping-pong basis with transmission bursts from all the active transmitters in the base unit being synchronised with one another. This prevents blocking of receiver sections due to co-sited transmitters transmitting at the same time on a different channel. The difficulty of synchronising the transmission bursts of the active portable units with their respective transceivers within the base unit is overcome by allowing the portable unit to make an initial continuous call comprising multiple identical sequences of data containing units small enough to be completely received within the limited reception windows of the base unit. After the initial call has started communication, an exchange of signals takes place on a ping-pong basis to establish synchronism between the portable unit and base unit. Finally, if all is well, the system reverts to speech mode.
