Title: Multispecific antigenic proteins
Inventor: HAYNES JOEL R
IPC: C12N7/00
Filed: 1985-08-20
Granted: 1999-10-05
Abstract: A novel conjugated protein produced by recombinant DNA techniques comprises a low molecular weight carrier protein portion that is normally self-aggregating to an immunogenic higher molecular weight proteinaceous material and a hapten portion wich is a peptide fraction that contains an epitope for an antigen for a pathogenic disease attached to the low molecular weight carrier portion. On aggregation of the self-aggregating protein, the hapten is on the surface of the viral particle, allowing for recognition of the hapten by the immune system. Upon introduction in vivo, the viral protein produces antibodies to both the self-aggregating protein and the hapten.      A plurality of the conjugated proteins having different haptens can be combined into a viral protein to provide multi specific vaccines conferring immunity to a variety of pathogenic agents.

Title: Method of and circuit arrangement for switching- through a radio connection to another radio cell of a digital radio transmission system
Inventor: SCHMIDT WERNER
IPC: H04W36/08
Filed: 1987-03-05
Granted: 1990-08-14
Abstract: ABSTRACT Method of and circuit arrangement for switching-through a radio connection to another radio cell of a digital radio transmission system. Base radio stations are spatially arranged in a radio transmission system in accordance with a cellular system, separating the message transmission channels from adjacent base stations being effected either by using the frequency-division multiplex method or by using the code-division multiplex method or by using a combination of these multiples methods. In appropriately large spatial distances the same set of channels can be repeated in a further radio cell. If a mobile radio station moves during the conversation from one radio cell into another, then it is necessary to switch-through the then existing radio connection. Additional receivers are provided in the base stations and after comparing the receiving voltages at the output of the additional receivers, a switch is made, when a predetermined threshold value is fallen short off, to that additional receiver at whose output the highest receiving voltage is found. To avoid the necessity of using such additional receivers in each base station and to prevent a repeated switch forward and back in the event of high co-channel interferences the measurements to be effected for the radio cell allocation and consequently for the switch-through decision are effected in the mobile radio station. In that situation the reception quality of the co-channel message transmission channels of remote base stations are additionally measured in the mobile station during the existence of a radio connection to a near base station.

Filed: 1987-03-09
Granted: 1990-11-27
Abstract: ABSTRACT OF THE DISCLOSURE           An electronic automatic transmission controller is provided which is adapted to enable electrical control over automatic transmission devices of the type typically used in motor vehicles.  The controller employs a manifold having a number of solenoid valve assemblies mounted thereto.  The solenoid valve assemblies feature a low stacked height achieved through the configuration of the valves and various improvements in force output for the solenoid valve assemblies.  The solenoid valve assemblies are held in an assembled condition through the action of a bracket assembly which has resiliantly deflectable arms which bias against the valve assemblies. Preferably, non-removable fasteners are employed to affix the bracket to the manifold to prevent unauthorized attempts at servicing.  The solenoid valve assemblies have protruding terminals which enable a circuit board to be laid against the solenoid valve assemblies such that the board is soldered along a surface opposite the valve assemblies.  The automatic transmission controller further feature a design which permits automated assembly, thus reducing costs of fabrication.  In addition, various improvements in solenoid design are described including a dual working gap system and a design which enables control over spring biasing of a solenoid armature and air gap distance.

Abstract: A B S T R A C T            The IBM 370 Input/Output (I/O) architecture separates I/O devices very strictly from the central processing unit and its main memory. The  I/O devices can access the memory only through the channel which takes care that only accesses to authorized spaces are performed.            The invention provides a control intèrface that allows the I/O devices to communicate with the memory directly. The memory space available for data transfer is provided to the l/O devices by two continuously running transfer mechanisms one for inbound and one for outbound data transfer traffic. These mechanisms provide a series of buffers which are con-trolled by pointers indicating which buffers are full and which ones are empty. The current pointer values are ex-changed between an application and an I/O device by a third continuously running mechanism. Pointers changed are re-cognized by the application or by the I/O device control. The software can get control after a data transfer operation has been completed by using an interrupt mechanism. The interrupt mechanism can be tuned by the application by specifying threshold values and timers.

Abstract: ABSTRACT OF THE DISCLOSURE         A stationary reciprocating compressor is disclosed of the type driven by an electric motor.  The compressor is used for natural gas used as a fuel in motor vehicle engines and stored in the compressed state in the vehicle to be driven by the gas.  There are four cylinders arranged in series on the gas side.  The pistons of the cylinders are so arranged that at a time two of them lie opposite one another on a common axis.  They are interconnected with their piston rods by way of a yoke to form a pair.  The axis of the two pairs of pistons so formed intersect each other.  Each pair of pistons is disposed in a substantially horizontal plane.  A common crank pin, serving as driving means, engages in the two yokes of the piston pairs by way of a slider.  The gas to be compressed is supplied on the piston side remote from the compression chamber of the first compression stage by way of at least one suction valve situated in the piston.  The drive motor for the compressor is situated below the horizontal planes of the two piston pairs.  The invention reduces the noise generated by the compressor and the driving torque at the time of the start so that the electric motor can be connected to the usual supply of power.
