Abstract: A CW radar comprises a substantially continously operable transmitter (10) and receiver (16,18,20), signal operating means (12,14) for radiating the transmitter signal and for receiving at least the return signal and a reflected power canceller (RPC) circuit (26, 28 and 30) for cancelling leakage signals in a signal path from the signal operating means to the receiver. The receiver front end comprises quadrature related mixers (18,20) which supply intermediate frequency signals (I₁ and Q₁) to a low frequency control loop (32, 34, 36) which supplies at least a pair of control signals (I c ,Q c ) to a four quadrant vector modulator (28) in the RPC circuit. In order to be able to optimise the cancellation of phase as well as amplitude, the control circuit loop includes means for synthesising control vectors (I₁, -I₁, Q₁ and -Q₁) from the outputs of the quadrature related mixers (18,20). Selecting means selects a pair of quadrature related control vectors from those control vectors synthesised on the basis of minimising leakage in the outputs of the quadrature related mixers (18,20). The selected control vectors (I c ,Q c ) are applied to the four quadrant vector modulator (28) which preferably comprises a pair of analogue driven biphase modulators (56,58 - Figure 4 (not shown)). In an alternative embodiment (Figure 7) the four quadrant vector modulator comprises four voltage controlled attenuators to which respective control vectors (I c , -I c , Q c  and -Q c ).

Abstract: A DNA sequence encoding the human platelet-derived growth factor receptor (hPDGF-R) has now been isolated and sequenced. An expression construct comprises the sequence encodes a receptor that can be secreted or incorporated into the membrane of a mammalian cell. The incorporated receptor is functionally equivalent to the wild-type receptor, conferring a PDGF-sensitive mitogenic response on cells lacking the receptor. The construct can be used for enhancing PDGF response of cells, determining the regions involved in transducing the signal in response to PDGF binding, providing mutated analogs and evaluating drugs for their physiologic activity.

Abstract: A method and apparatus for laying down a weft filament. The weft yarns are propelled over a moving substrate, whereupon they are clamped and pulled down into the substrate. The apparatus propels the filaments (102) through an elongate hollow chamber (54) where they are clamped by clamping means (74). They are then transferred from the chamber onto the substrate. By pivotting the apparatus the angles at which the filaments can be layed onto the substrate can be carefully controlled enabling hitherto unobtainable products to be produced.

Abstract: Excellent stabilization of polypropylene (PP) fibers exposed to sterilization levels of gamma radiation, is obtained with a hybrid stabilizer having a N-(substitut­ed)-1-(piperazin-2-one alkyl) group at one end and a (3,5-­dialkyl-4-hydroxyphenyl)-α,α-disubstituted acetamide at the other. When this hybrid of a hindered amine with a hindered phenol is combined through a disubstituted alpha carbon atom of the acetamide in a single molecule, it affords the advantages of each group with respect to its stabilization against oxidation, but without the known inherent disadvantages of either group. This molecule is N-(substituted)-1-(piperazin-2-one alkyl)-α-(3,5-dialkyl-­4-hydroxyphenyl)-α,α-substituted acetamide molecule ("3,5-­DHPZNA" for brevity). The unexpected retention of tensile strength in 3,5-DHPZNA stabilized PP fibers used in articles exposed to a sterilizing dosage level of gamma radiation, is of great practical value.

Abstract: A method and an apparatus for automatically composing a program for conducting sequential control of operations which are successively performed by various equipment units for a production line. These operations are grouped into operation blocks each having a sequence of unit operations so that each operation block can be conducted independently of the other blocks. Standardized step ladder patterns for the operation steps constituting each operation block is stored before the program composition. First data for describing the operation blocks and the ordinal relationship between the operation blocks is input. Second data for describing specific operations of the operation steps constituting each of the operation blocks and third data designating the order of execution of the operation steps are input and stored. The step ladder pattern corresponding to one of the operation steps constituting each operation block and the second data for this operation step are read out. The second data is appended to the read step ladder pattern to form a step ladder element. These operations of reading and step ladder element formation are repeated with respect to the operation steps in order of upper to lower operation steps based on the third data. This operation is performed with respect to all the operation blocks based on the first data.

Abstract: A totally integrated thermal imaging system having a dewar housing (12) including imaging optics, a scanning mirror (16) and a curved detector array (20). The imaging optics constitute a meniscus lens (14) and a spherical focusing mirror (18). The scanning mirror (16) scans the image, and the spherical mirror (18) focuses the scanned image onto the detector array (20). The meniscus lens (14) advantageously corrects aberrations. A detector support (26) provides access for cryogenic cooling of the detector (20), and individual cold shielding of the detector elements is made possible by the telecentricity of the optics. Processing electronics, at least a portion of which may also be disposed on the detector support (26), process the detector signals to display an image. The integrated structure advantageously eliminates any need for separate scanner, imager, detector dewar and electronics modules.

Abstract: A method is provided to compensate for tape slope (A) and read/write head block (102) azimuth (B) errors in a tape drive system (100). The method writes a data pattern (504) on a magnetic medium (104) at a known slope (C). The portion of the magnetic medium (104) that is encoded with the data pattern (504) is then moved across the read/write head block (102), so that first one read head (154) and then the other read head (152) detects the recorded data pattern (504). The time difference (ΔT ON ) between the event of each head (154, 152) first sensing the data pattern (504), and the time difference (ΔT OFF ) between the points where each head (154, 152) no longer detects the data pattern (504), are both recorded. The recorded information is used to analyze the angular offset (A-B) between the centerline (192) of the tape (104) and the centerline (194) of the read/write head system (102). The angular offset (A-B) is used to determine a lateral displacement (D) between the two read heads (154, 152) in a direction perpendicular to the centerline (192) of the tape (104). The lateral displacement (D) is used to adjust the stepping distance between data tracks recorded in a first (i.e., forward) direction and a second (i.e., reverse) direction on the tape (104) so that the respective read head (152, 154) is positioned substantially on the center of the respective recorded track.

Abstract: A method for modifying the frequency of a clock signal includes the steps of producing a clock signal having voltage pulses which occur at a first frequency and producing a control signal having voltage pulses which occur at a lower frequency. The frequency of the voltage pulses in the control signal is incremented in successive time intervals and the clock signal and control signal are combined such that one voltage pulse in the clock signal is deleted for each voltage pulse in the control signal. This results in a modified clock signal having a frequency which may be ramped up or down depending upon the initial frequency of the control signal and the direction in which, the frequency of the control signal is incremented.
