Abstract: The instant invention relates to a novel method for the delivery of antitumor drugs to tumor cells by the administration of a tumor-selective antibody- β-lactamase conjugate that binds to tumor cells, and the additional administration of a cephalosporin prodrug that is converted at the tumor site, in the presence of the antibody-β-lactamase, to an active cytotoxic drug. According to the preferred embodiment of this invention, a cephalosporin mustard has been constructed which when cleaved by β-lactamase yields a cytotoxic nitrogen mustard. The methods, antibody-enzyme conjugate, prodrugs, pharmaceutical compositions, and combinations of this invention provide for enhanced selective killing of tumor cells and are thus useful in the treatment of cancers and other tumors.

Abstract: Images are presented on a display (206) to produce the perception of viewpoint motion in a three-dimensional workspace. The user can indicate a point of interest (POl) or other region on a surface in an image and request viewpoint motion. In response, another image is presented from a viewpoint that is displaced as requested. The user can request viewpoint motion radially toward or away from the POl, and can also request viewpoint motion laterally toward a normal of the surface at the POl. Radial and lateral viewpoint motion can be combined. The orientation of the viewpoint can be shifted during lateral motion to keep the POl in the field of view, and can also be shifted to bring the POl toward the center of the field of view. In a sequence of steps of viewpoint motion, the radial viewpoint displacement in each step can be a proportion of the distance to the POl so that the radial displacements follow a logarithmic function and define an asymptotic path that approaches but does not reach the POl. One proportion can be used for approaching the POl and another for retreating from the POl, so that an approach step followed by a retreat step returns the viewpoint to the same position. Similarly, each step's lateral viewpoint displacement can be a proportion of the distance to the normal, either along an arc or a chord, so that the lateral displacements define an asymptotic path that approaches the normal. The proportion for lateral displacements can be greater than that for radial approach, so that the viewpoint reaches the normal more quickly than it reaches the POl. While requesting viewpoint motion with a keyboard, the user can independently request POl motion with the mouse. In response, the POl moves within the bounds of the surface that includes the POl, and a shape within the image indicates the POl position.

Abstract: In detecting a distortion angle in a textile material being conveyed in a direction of conveyance, the textile material is scanned by means of a first sensor whose output signal depends on an angular position of the sensor relative to the direction of conveyance and on the distortion angle. The sensor output signal is filtered via filter devices in such a way that signal components are filtered out of the output signal which are (statistically) independent of the distortion angle. It is proposed to adjust the filter devices with respect to their pass characteristic, their centre frequency, their bandwidth and/or their filter curve shape by means of a second output signal of a second scanning device, the second output signal depending on the frequency characteristic of those signal components from the first output signal which are statistically dependent on the distortion angle. It is possible in this way to match the pass characteristic of the filter devices to the signal components dependent on the distortion angle, and thus easily to detect the distortion angle.

Abstract: A device (1a) is used for preliminary testing particularly of a load having inductance for overload or short circuit, before connection to a power supply network. For this purpose, after switching on for load preliminary testing, the load initially has applied to it small gated voltages or voltage sections, the gated voltages or voltage sections gradually increasing. The in-phase current is measured in a narrow time window at the start of each application of voltage. If the said current does not exceed an in-phase current limit value, which can be predetermined, during a specific effective application of voltage, then the load is connected to the network. If this is not the case, the switching-on process is terminated. This switching-on method avoids a high load on the network in the event of a short-circuit or an overload. The in-phase current measurement window in each case starts when the voltage is applied to the load. A further measurement window, separated from this time window, is provided for the reactive current, this measurement window starting with the zero crossing of the AC voltage. The measurement of the reactive current is used to identify a defined magnetisation end position of the load which has inductance, in order to be able to connect the said load to the network in the correct phase and without a switching-on current surge. <IMAGE>

Abstract: The invention relates to a method for manufacturing rectangular frames, especially window frames from plastic profile sections, in which method four plastic profile sections which have been cut to length and mitred are clamped into a four-head welding machine using exchangeable welding inserts corresponding to the profile cross-section and are welded together at all the mitred surfaces simultaneously while being subjected to heat and pressure, welding beads being formed, and in which the frames are subsequently delivered to a trimming machine for machining of the welding beads which have formed. In order to be able to carry out the method in a relatively small space without excessive investment costs and to ensure that the capacity of a modern and rapid corner-trimming machine can be exploited in an economical fashion, at least two four-head welding machines which are arranged on a turntable are alternately provided with the plastic profile sections and the plastic frames are alternately welded.

Abstract: Optical metrology method and apparatus wherein three optical wavelengths are generated and separated into a reference beam (RB) and an object beam (OB) having substantially equal optical path lengths. After reflecting from a surface being measured OB is combined with RB and provided to sensors which measure the intensity associated with each of the wavelengths. Any difference between the intensities is indicative of a difference in the optical path lengths of OB and RB arid is a function of the polarization state of each of the three retumed wavelengths. Differences in optical path length are shown to be indicative of a displacement of the object being measured. Preferably, two multimode laser diodes (12, 14) are provided for generating the three optical wavelengths. Two synthetic wavelengths are derived from the three optical wavelengths and are employed to improve the precision of measurement while retaining a large dynamic range made possible by the use of a large synthetic wavelength.

Abstract: Gas permeability of very low permeability subterranean formations, and the gas permeability reducing effects of injecting one or more treatment fluids thereinto, are measured by injecting a gas into a core sample of the formation at a selected substantially constant pressure, and continuing the injection for a long period of time to ensure steady state flow conditions. The temperature of the gas as it flows through the core sample and the flow rate of the gas exiting the core sample are measured, and the native state gas permeability of the core sample is calculated therefrom. One or more treatment fluids can be injected into the core sample after the native state permeability is determined. Thereafter, the gas permeability can again be determined and compared to the native state permeability.
