Abstract: Liposome Conjugates and Diagnostic Methods Therewith Abstract A number of naturally occurring antibodies to human erythrocyte surface antigens are capable of combin-ing with their specific antigens (for example, Rhesus factor),  but  are  not  capable  of  producing  visible hemagglutination.  Also, the sensitivity of many diag-nostic methods, such as in human blood typing, depends upon cell agglutination.          The  present  invention  provides  liposome-protein   conjugates,   especially   useful  for   he-magglutination assays, having an enhanced agglutination capacity with respect to antibody from which the conju-gates are derived.

Abstract: ABSTRACT            A method and devices for applying the generally known principle of cascade flow in control of self-adjusting fluid handling systems, which devices are capable of maintaining predetermined flow rate/pressure difference ratios, over a wide range of variations. The capability of maintaining predetermined flow rate/ pressure difference ratios is based on a capability of maintaining predetermined displacement/Pressure difference ratios of axially displaceable means of control in application of the principle of cascade flow. One embodiment is a draught control device, which is capable of maintaining substantially constant draught, e.g. in central heating boilers of solid fuel, over a wide range of variations in flue pressure. Another embodiment is a constant flow valve, capable of maintaining constant rate of volume flows in house ventilation. A third embodiment of the present invention is a constant pressure valve, capable of maintaining constant pressure of fluid upstream the valve.

Abstract: ABST~CT OF THE DISCUSSER     The apparatus of the present invention comprises an elongated body, a tractor, means for attaching the body to the tractor r and an elongated blade assembly extending along the body and being rotatable mounted thereto for rotation about a horizontal axis.  The blade assembly comprises an elongated shaft having a plurality of paddle members mounted in spaced relation to one another, and extending radially outwardly from the shaft.  A plurality of wear plates are attached in covering relation over the paddle members. The wear plates protect the paddle members from wearing, and are individually replaceable as they themselves become worn or damaged. A modified form of the invention utilizes replaceable paddle members rather than wear plates.  The method of the present invention contemplates replacing the wear plates after usage, or in the alternative, replacing the paddle members after they have become worn and damaged.

Abstract: ABSTRACT OF THE DISCLOSURE        A radiation measurement means is shown which has the capability of detecting radiation in both the millimeter wave, and the infrared, frequency regions.  A basic self-oscillating Gunn diode is enclosed in a donut shaped silicon ring.  The presence of infrared energy will create holes and electrons in the silicon material, altering its conductivity, and lower the power of oscillation.  The realized drop in oscillating power identifies the infrared.          Millimeter wave radiation is detected because an intermediate frequency is generated as the Gunn diode operates as a self-oscillating mixer of the new different frequency with its own oscillating frequency.  Thus it is possible to detect signals from both ranges, in a single device.

Abstract: PRIORITIZED UNIT DIRECTIONAL DISTRIBUTED            Abstract of the Disclosure A plurality of bus interface units (BIUs), capable of placing information packets on a unidirec-tional transmit bus, are coupled to the transmit bus at locations spaced therealong.  Each BIU comprises a transmit bus input port and a transmit bus output port, wherein the transmit  bus input port of each BIU is coupled to the transmit bus output port of the next upstream BIU, and a receive bus input port connected to a receive bus.  Each BIU includes a memory for storing at least one information packet to be trans-mitted and a control circuit associated with the memory.          In a passive mode, the control circuit operates the BIU like a repeater, wherein packets received on its transmit  bus input are reconstituted and retransmitted on its transmit bus output.  In an active mode, the control circuit causes the BIU to transmit information packets stored in its memory.  Each information packet may have a predetermined priority.  The control circuit aborts transmission of an information packet whenever the BIU receives a higher or equal priority packet than it is transmitting and transmits the received packet in lieu of the aborted packet.  Packets received during transmission, having lower priority than the packet being transmitted, are stored in memory for later transmission.

Abstract: ABSTRACT The interior of a metal housing is divided by a dielectric substrate into two connpartments. At least one of the compartments is kept air-tight. The substrate carries thereon a semiconductor active element chip for oscillation within the air-tight compartment and a dielectric resonator within the other comparment. The chip and the resonator, electromagnetically coupled with the chip, constitute a microwave oscillator whose oscillation frequency can be stabilized. A metal screw is threaded into that wall of the housing which defines the other compartment in a predetermined positional relationship to the resonator. The metal screw is rotatable to vary the distance between the screw and the resonator and, thereby, the oscillation frequency.

With the discrete distributed coupling elements,  the frequency of the driving signals and the phase relationship between the driving signals is such as to create a simulated travelling acoustic wave in the fiber.  The real or apparent travelling acoustic wave in the fiber causes light propagating through the fiber to be coupled from one of the fiber modes to another of the fiber  modes,  and  to  cause  the  coupled  light  to  be frequency  shifted  relative  to  the  initial  light.   The wavelength  of  the  real  or apparent  acoustic  wave  is approximately equal to an integer multiple of the fiber beat  length  to  cause  constructive  coupling  of  the frequency shifted light.
