Title: Method and apparatus for on-line filtration removal  of macromolecules from a physiological fluid

Abstract: METHOD AND APPARATUS FOR ON-LINE FILTRATION REMOVAL     OF MACROMOLECULES FROM A PHYSIOLOGICAL FLUID          ABSTRACT OF THE INVENTION  An on-line filtration system for the removal of macromolecules greater than 70,000 mol. wt. from a physio-logical solution, such as blood, in the therapeutic treat-ment of various disease states.  For blood, the plasma (which contains the macromolecules) is separated continu-ously from the blood using a first membrane filter with a membrane porosity of nominally 0.2 to 1.0 micron.  The separated plasma is then continuously filtered in a physi-ological temperature state or a cooled state through a second membrane filter with a membrane porosity of nomi-nally 0.01 to 0.2 micron, which retains the macromolecules. In the cooled state, separation of the macromolecules is effected more efficiently than could be done in the non-cooled state.  The treated plasma (macromolecules removed) is then reunited with the blood flow coming from the first plasma filter and returned to the patient.  The blood flow and filtration processes are generally continuous.  Suit-able agent(s) may be added to the separated plasma to promote formation of macromolecules.

Abstract: HITCH CONTROL SYSTEM WITH SINGLE LEVER CONTROL  Abstract of the Disclosure A hitch control system includes a position control lever coupled to a transducer which produces desired position signals, a draft force sensor and a hitch position sensor.  A push-button switch is mounted in the control lever housing.  A signal processor stores selected values of the sensed draft force in response to actuation of the push-button switch.  The signal processor generates position error signals from the desired position and sensed position signals, and generates a load error signal from the sense draft force and the stored selected draft force values.  The hitch is controlled as a function of these errors.

Abstract: REMOTE LUBRICATION SYSTEM FOR HYDROSTATIC DRIVE           Abstract A fluid motor is connected to a winch at a remote distance from a hydrostatic pump and reservoir; a part of the hydrostatic fluid is used as a lubricant for the winch and is connected beneath the winch in a sump. The level of the fluid in the sump is controlled by a venting orifice and float arrangement and air pressurization in the sump above the level of oil. As the level increases, the orifice becomes closed by the float, and the air pressure forces the oil out of the discharge line of the sump to lower the level of oil.  When the oil level falls, the orifice is opened and the pressurized air is vented to atmosphere, allowing the oil level in the sump to rise.

Abstract: ABSTRACT OF THE DISCLOSURE     A device and method for controlllng ectoparasites on agricultural livestock is disclosed which gives improved long term application of a pesticldal compositlon directly to the most frequently infeste areas on the livestock.  The pesticidal device hereof comprises an elongated, flexible, synthetic resin carrier strip which includes an incorporated volatile or non-volacile pesticide.  An attachment is provided for fastening the device in cantilever fashion from an appendage of or an object worn by the animal, or to a portion of an animal confinement area, so as to assure that the device comes into repeated or continuing contact with adjacent portions of the animal's body.  The device is advantageously of a length for free swinging movement thereof in response to the natural movement of the animal, thereby releasing the incorporated pesticidal composition from the device for direct application to a relatively large portion of the animal's body.  Indirect application of the pesticide to the remaining portions of the animal's exterior surface is accomplished by diffusion of pesticide from the application site.

Abstract: "INSULATED SIDING AND METHOD FOR ITS APPLICATION"          ABSTRACT OF THE DISCLOSURE           An insulated siding panel comprises a panel of hardboard attached by adhesive to a polystyrene foam layer.  The rear surface of the foam layer is parallel to the front face of the hardboard panel.  The upper and lower faces have parallel V-shape with the upper face having the V inward for collection of moisture.  The panels are installed by overlapping the hardboard of two adjacent panels to allow the foam layers to interlock leaving a space for a sponge layer.  Channels are formed in the foam downwardly between the hardboard and the foam and across the bottom of the foam to provide an intercom-municating network to transmit moisture vapor.  The panels can be nailed to the front face of a building using a spacer device to set the distance of the upper edge of the panel from the front face of the building to prevent compression of the foam.

Abstract: Abstract Of The Disclosure The disclosure provides a unique multiprocessing (MP) method for executing on plural CPUs of the MP a uniprocessor system (UPS) program not written to run on a MP system.  Separate copies of the UPS are provided in the shared main storage (MS) of the MP.  A hypervisor type of control program (called a partitioned multiprocessing system, PMP) uses the MP method to enable simultaneous execution of the plural copies of a UPS on different CPUs of the MP as UPS guest virtual machines.  PMP can dedicate any CPU to the sole execution of a particular copy of UPS.  The copies of the UPS run on the different CPUs independently of each other, but they may share I/O devices.  PMP may run with a virtual machine (VM) type of job entry and task dispatching control programming system designed to operate on CPUs having 370-XA architecture and to use emulation on the CPUs to permit a UPS designed for the same or another architecture (e.g. S/360 or S/370) to execute on the 370-XA CPUs as a UPS guest by using an emulation instruction (e.g. start interpretive execution, SIE).   Efficient direct I/O handling for the executing UPS copies (i.e. UPS guests) requires the MS boundary of each UPS to be located at a different 2n byte absolute address, so that the I/O processor can easily translate channel program and I/O data addresses used by each UPS to the actual absolute MS addresses of the MP, n being the number of bits in the effective address used by the UPS.  Zone parameters are derived from the 2n boundary addresses for the respective guests.  This channel translation does not require any translation tables and can avoid a MS access for each translation.  A CPU may use segment and page tables to translate UPS addresses for any UPS guest's CPU requests.

Abstract: Abstract of the Disclosure A heater module having a cylindrical heat exchanger surrounding a central cavity and burner wherein an end mani-fold is covered with a layer of insulation to reduce the temperature differential between the outer annular trough of the manifold and the inner central flat disk which covers the end of the cavity.  The annular trough and the disk are stamped from a unitary piece of plate steel.  Without the insulation, the disk would heat to a temperature much higher than the annular trough because the trough communicates with tubes of the heat exchanger and contains recirculating liquid.  By reducing the temperature differential, less strain is put on the end manifold as a result of nonuniform expansion.
