Granted: 1990-11-13
Abstract: IMMUNOGENIC CONJUGATES         ABSTRACT            An immunogenic conjugate which is the reductive amination product of an immunogenic capsular polymer fragment having at least one reducing group and derived from a bacterial capsular polymer of a bacterial pathogen, and a bacterial toxin or toxoid.  The invention also relates to methods for the preparation of the conjugates a vaccine containing the conjugates which elicits effective levels of anti-capsular polymer antibodies in humans.  Also disclosed are methods for inducing active immunization against systemic infection in young mammals caused by bacterial pathogens comprising the administration of an immunogenic amount of the above-described conjugate.  In a preferred embodiment, the capsular polymer fragment prior to conjugation has at least one aldehyde group at each end of the fragment.  The final conjugate made with such capsular polymers has a lattice or network structure, and provides extremely high levels of anti-capsular polymer antibodies in infants.

Title: Dry blending with fibers
Inventor: LEE DONALD M
IPC: B29B15/00
Filed: 1987-06-01
Granted: 1992-05-12
Abstract: ABSTRACT OF THE DISCLOSURE           Disclosed is a method and apparatus for avoiding the clumping of dry fibers having diameters and lengths in certain ranges during blending of such fibers into a dry or wet particulate material. The process comprises distributing fibers in a vaporous medium, and transporting fluidized fibers to a mixing zone containing a dry or wet particulate material. Concurrently with stirring and blending of the particulate material with fluidized fibers, the fluidized fibers having been separated at least partially from a fluidized vapor are gradually introduced into the mixing zone. This process avoids the phenomena of "balling" that otherwise occurs with certain fibers.     6274mus

Abstract: ABSTRACT OF THE DISCLOSURE          A frequency synthesizer with a voltage-controlled oscillator that can be tuned over its total frequency range in increments of a prescribed frequency range a frequency-dictating component and with a reference oscillator that emits a reference signal of a strictly prescribed frequency that is supplied in the form of an input signal to a comparator, to which is simultaneously supplied another input signal of a frequency that is a function of the frequency of the output signal from the voltage-controlled oscillator, the second input signal generating a fine-tuning signal in accordance with the difference between the frequencies or between the phases of the first and second input signals and the fine-tuning signal supplied to the voltage-controlled oscillator to fine-tune the frequency of its output signal to the level defined by the reference signal. The second input signal supplied to the comparator is generated by a variable frequency divider that is adjusted by means of a variable electronic setting component, to which the fine-tuning signal is supplied and which continues to vary the dividing factor of the frequency divider until the voltage of the fine-tuning signal assumes a defined level within a prescribed range of voltages that fine-tunes the frequency of the output signal from the voltage-controlled oscillator to the frequency of the second input signal multiplied by the dividing factor so obtained, whereby the frequency of the output signal is within the subsidiary frequency range prescribed by the grid and set at the frequency-dictating component.

Granted: 1992-04-28
Abstract: "Concentrator System Capable of Completing Emergency Calls Under Congested Traffic"                   ABSTRACT OF THE DISCLOSURE    In a radio concentrator system formed by a central station and remote stations, demand-assigned data channels are constantly monitored to detect when they are congested. When an emergency call is received from a subscriber terminal, a dial tone is sent to the terminal if the emergency call occurs simultaneously with the detection of a congestion. On hearing the dial tone, the subscriber dials an emergency destination address, which is received by a remote station and compared with a list of predetermined addresses and verified if it matches one of the predetermined addresses. The dialled information is sent from that station to the central station, where it is relayed to a switched network.       An emergency channel is established to the network for routing the emergency call. This channel may be permanently provided and demand-assigned in response to an emergency channel assignment request, or first selected by a remote station requesting an emergency call and access is granted by the central station if no collision occurs between competing emergency calls. Alternatively, no emergency channel is provided in the system and one of the data channels is cleared when an emergency call is detected simultaneously with the occurrence of a congestion. The cleared channel is used as an emergency channel to complete the emergency call.
