Abstract: The invention is the combination of a computer or word processing device with a program which controls the operation of the system to accept the data entries into data fields in the memory of the system, in conjunction with codes that designate a specific data field, the relative location of the data field on a preprinted form and prompt to indicate to the operator what data should be entered in that field and the method of offsetting of the data entries from their designated locations to align the data entries with the date fields of the preprinted form. The relative location of the data location is stored with a unique code known as a "mark". The mark code may have an annotation stored with it so that the operator is prompted as to what entry is appropriate for that mark. Also stored with the mark is a location value or values which define the relative location of the data field with respect to some assumed datum location.

     Plastics matter is supplied by way of three connections (26, 28) at the base of the column and is, by axial passages (22, 23, 29) transferred to different levels within the column, and is then, by radial continuation passages (30, 31, 32) led to separate cylindrical interfaces (16, 17, 18), from which the matter by way of radial passages (36, 37, 38) and axial passages (39, 40, 41) in the head are fed to a common extrusion slot (15). One of the flows of plastic matter (from connection 26) is brought to pass the rolling bearings (12, 13), which hereby are effectively lubricated and cause an extra working of the plastics matter. 
     Adjustable gland packings (43, 44) are located outside the flow passages at the cylindrical interfaces.

Abstract: The present invention relates to a system for the generation of antibody fusion proteins which has utility in the production of recombinant molecules that possess novel, clinically relevant biological activity. The antibody fusion proteins of the invention may be used therapeutically to deliver biologically active ligands to a desired tissue. 
     In particular embodiments of the invention, the antibody fusion protein comprises a biologically active ligand which is a lymphokine, including, in a specific embodiment, interleukin-2. Because interleukin-2 induces lymphocyte proliferation, fused antibody that targets interleukin-2 (IL-2) to a malignant or infected tissue can produce localized amplification of the immune response toward the diseased tissue, and thereby facilitate the destruction of the infected or malignant tissue. In a specific embodiment of the invention, a fused antibody is produced which comprises a variable region of the anti-tumor antigen monoclonal antibody L6 and active IL-2. 
     Additional embodiments of the invention relate to fused antibodies which comprise an immunoglobulin variable region and a biologically active ligand which is a non-lymphokine cellular factor. In a specific embodiment of the invention, a fused antibody is produced which comprises a variable region of the anti-tumor antigen monoclonal antibody L6 and active platelet factor 4, a molecule associated with antagonism of angiogenesis, inhibition of suppressor T lymphocyte development, chemotaxis and heparin binding.

Abstract: In a CT image of a living body, contours of internal organs thereof are discriminated. Parameters are beforehand stored in a memory for a plurality of internal organs of the living body. Applicators (14A,14B) are attached onto the living body (A) and then a high frequency power is applied to electrodes (15A,15B) disposed therein so as to heat an internal portion of the body (A). Based on an intensity of an electric field generated in the body (A) due to the applied power and the parameters stored in the memory, a temperature distribution on the CT image is estimated. To retain an estimated temperature of an objective tumor at a predetermined target temperature, the high frequency power and the cooling water in the applicators (14A,14B) are controlled. In the estimation of the temperature distribution, the parameters of the living body (A) are repeatedly corrected to minimize a discrepancy between a temperature measured at a preset position and an estimated temperature associated therewith.

Abstract: A method of and apparatus for dynamically mechanically bonding together a plurality of laminae, at least one of which comprises thermoplastic material: for example, polyethylene. In one aspect of the invention the laminae are forwarded in face to face relation through a pressure biased nip between a patterned nip defining member and an opposing nip defining member (eg, a relief patterned cylinder and an anvil cylinder) which members are independently driven to maintain a predetermined surface velocity differential between them. In another aspect of the invention which is particularly useful at intermediate and higher line velocities --preferably for line velocities of about 300 feet or more per minute and, more preferably, for line speeds of about 450 feet or more per minute -- the nip defining members say be operated with equal surface velocities. In each of these aspects of the invention, the members may be biased towards each other to provide a predetermined pattern-element-psi loading; and, additionally, they may be independently heated to provide each with an elevated surface temperature which is, preferably, in a predetermined range below the melt temperature of the thermoplastic lamina disposed closest to or in contact with each respective nip defining member as the laminae are forwarded through the nip.

Abstract: A circuit for generating an analogue signal by way of digital-to-analogue conversion, such as a direct digital frequency synthesiser (Fig. 3) of the type including a frequency number generator 12, phase number accumulator 13, function number generator 14, such as a look-up table of sine values, and DAC 15 mitigates the production of analogue signal errors, manifested as spurious frequency signals, by modifying the digital number representing each function value with a random digital number added or subtracted in ALU 22. The randomly modified function number and random digital number are converted to analogue values in DAC 15 and further DAC 28 respectively and the analogue values combined to remove the effect of the random number. Because conversion in DAC 15 is spread randomly over all DAC levels, even when the function number is not, any conversion errors associated with any DAC steps which by repeated use would be manifested as spurious frequency signals are decorrelated to broadband noise. Less troublesome correlations due to function number truncation may be mitigated by limited random dithering of the phase number (Fig. 6) and randomly dithering rounding of the function number (Fig. 5).A similar circuit (100, Fig.10) generating a sawtooth signal may be employed in improving phase control linearity in a phase locked loop frequency synthesiser.
