Abstract: A master disk (20) is positioned such that a radial portion thereof is within a restricted field having good imagery of an optical projection system (10). A second blank disk (22) is positioned such that the image location extends along a radial portion thereof. As the two disks are rotated synchronously a pattern in an annular area is formed on the blank disk (22) replicating the master (20). Good imagery of the pattern is obtained with a simple system having an image field less than the size of the object being reproduced.

Abstract: Test strips for an analytical determination of a component in a fluid sample, in particular for the diagnosis of illnesses. Located on a base layer (2) are a sample receiving region (4) and an evaluation region (6) which are connected to one another by a fluid transporting section. Arranged in the evaluation region (6) is a colour forming layer (11) in which an optically detectable change that is characteristic for the analysis takes place. 
<??>In order in the case of such a test strip to be able to control the orderly wetting of the test layers by means of longitudinal transport and thus to improve the dosing of the sample, there is arranged over the colour forming layer (11) in the evaluation region (6) an absorbent covering layer (7), which in the initial state of the test strip renders the colour of the colour forming layer (11) invisible. The covering layer (7) is in fluid contact with the fluid transporting section. The covering layer (7) and the colour forming layer (11) are constructed such that the colour of the colour forming reagent becomes visible when both layers are wetted by the sample fluid.

Inventor: LO YING-CHING
IPC: A61B17/00
Filed: 1989-09-13
Abstract: There is disclosed herein a driver system for an ultrasonic probe for allowing a user to have proportional control of the power dissipated in the probe in accordance with the position of power dissipation controls operable by the user and for automatically tuning upon user request such that the driving frequency is equal to the mechanical resonant frequency of said probe and such that the re­active component of the load impedance represented by said probe is tuned out. The system uses a tunable inductor in series with the piezoelectric crystal excitation transducer in the probe which has a flux modulation coil. The bias current through this flux modulation coil is controlled by the system. It is controlled such that the inductance of the tunable inductor cancels out the capacitive reactance of the load impedance presented by the probe when the probe is being driven by a driving signal which matches the mechanical resonance frequency of the probe. The resulting overall load impedance is substantially purely resistive. The system measures the phase angle and monitors the load current. This informa­tion is used to determine the mechanical resonance frequency by sweeping through a band of driving frequen­cies and finding the peak load current where the slope of the load current versus frequency function is greater than a predetermined constant. After the automatic tuning to the resonant frequency, the system automatically adjusts the bias current flowing through the flux modulation coil to maintain the substantially purely resistive load imped­ance for changing power levels. There is also disclosed herein an analog circuit to measure the Phase angle for the load driving signal and to adjust the frequency of the driving signal for best performance. This system includes an integrator to eliminate the effect of offset errors caused by operational amplifiers.

Abstract: An active phase quieting target highlight detector using phase and magnitude detection can discriminate sets of spatially-ordered highlights due to a target, from clutter or multipath echoes, along with nonsmoothed magnitude or envelope detection, and can better discriminate target structure due to reception of echoes from shorter active pulses. False target detection and multipath detection are reduced while detection of target structure is retained by a time domain detection scheme.

Abstract: The object of the present invention is a punching and nibbling machine provided with a device for automatically changing a pair of tools, of which one is a stationary die (7), and the other is a movable punch (8), which when set in working position, are both coupled with the respective die or punch holding unit (3, 4) on the common, vertical opera­tive axis (Y) of the punching and nibbling machine, charac­terized in that this tool changing device comprises two main magazines (5, 6), respectively for a set of dies (7), and for a matching set of punches (8). The said magazines (5, 6) are each provided with conveyor means (9, 10; 11, 12) for carrying the tools (7, 8) and for bringing the selected pair of tools (7, 8) into working position, in which their axis (X) is caused to coincide with the operative axis (Y) of the machine. The said conveyor means (9, 10; 11, 12) are so pro­vided that the tools (7, 8) are moved along a closed path, with their axes being substantially held in a plane passing through the operative axis (Y) of the punching and nibbling machine, and preferably lying across the machine main frame. The said conveyor means (9, 10; 11, 12) are so designed that the tools (7, 8) are not upturned while they are being con­veyed, so that no means are necessary for clamping each tool to the respective cartridge (14), and a remarkably simpli­fied construction of the magazines is thus attained.

Abstract: A screw cutting method for use with a numerically controlled machining system is improved by enabling finer finishing of the final screw surface. The invention allows the removal of scars formed during rough machining by offsetting the position of the rough machining passes in the direction of screw cutting, i.e., in the direction of movement of the tool during cutting, so that during the final fininshing pass, more material is removed from the screw surface opposing the cutting direction. Surface finish is further improved by specifically controlling the cutting depth in the cutting passes just preceeding the final cutting pass.
