Abstract: A toroidal continuously variable transmission comprises a friction roller (20) disposed between co-axial input (16) and output (18) discs and in driving contact therewith, and a roller carrier (26) rotatably supporting the friction roller. A hydraulic actuator (108) is operative to shift the roller carrier along a carrier axis. The hydraulic actuator is operable on hydraulic pressure supplied thereto by a ratio control valve (120). The ratio control valve includes a valve sleeve (120) (i.e., a first member) moveable along a valve axis, and a spool (128) (i.e., a second member) received in the valve sleeve and moveable along the valve axis, and means for regulating supply of hydraulic fluid to and discharge theeof from the hydraulic actuator in response to relative movement of the spool to the sleeve. A control arragmenet includes a stepper motor (122) for changing the sleeve from an intial position to a desired position. A cam (116) is connected to the roller carrier for unitary motion about the carrier axis. A cam follower (118) operatively disposed between the cam and one end of the spool. An adjustor (150) is provided between the cam follower and the one end of the spool for adjusting relation between the rotary motion of the cam and the corresponding linear motion of the spool.

IPC: G01N33/72
Filed: 1990-09-18
Abstract: A method is provided for predicting a property of a matter of biological origin, such as biological fluid, containing water, in a dynamic condition where the biological fluid may be approximated to contain two compartments where one compartment has a proportionally larger or smaller amount of water than the other compartment having the property of interest. The method involves establishing a training set in the near-infrared (NIR) region with independent quantification of the property of the fluid using known techniques. The training set is mathematically analyzed according to a correlation developed by regression analysis after employment of a pre-processing technique such as a multiple derivative transformation of spectra or a ratioing of two wavelengths in the spectra. The result is a mathematical transformation equation which quantitatively relates spectral intensities at specific wavelengths to the property of interest. This transformation equation may be applied to unknown samples so as to predict their properties, thereby eliminating need for the reference method except for validation or recalibration. The method provides rapid and accurate prediction of the property of the unknown sample, which may be the property of hematocrit or hemoglobin concentration in whole animal blood. Other analyses of properties in the biological fluid such as oxygen saturation in hemoglobin in whole animal blood may be included in the mathematical analysis to further refine the prediction of the property of interest. Also, a loop from the patient is disclosed for the purpose of monitoring the property of interest nearly simultaneously with changes in that property of interest.

Abstract: In a power monitoring circuit, AC power-line voltage is converted by a DC power supply (20) to a regulated DC voltage. The DC power supply shuts down itself in the event of an overvoltage or overcurrent. The output of DC supply rises from zero to a specified value in relatively slow response to power-on state and drops to zero in slow response to a significant drop in the AC voltage. A rectifier-filter (23) converts the AC voltage to a nonregulated DC voltage. The output of the rectifier-filter rises in relatively quick response to the power-on state and drops in quick response to the significant AC voltage drop. If the output of DC power supply drops below a specified threshold due to AC power-line failure or due to its own failure, a DC low-voltage signal is generated which is detected by a DC low voltage detector (22). If the output of rectifier-filter rises above a specified low level a first (normal) AC transitory signal is generated and if it drops below a specified high level a second (alarm) AC transitory signal is generated by an AC low voltage detector (25), at terminals (28). A latch circuit (26) is energized with the nonregulated DC voltage via an optical link (29) to latch the DC low-voltage signal if it occurs during the interval between the first and second AC transitory signals and supply a DC alarm signal to computer circuitry (30). A power controller (21) is energized with the regulated DC voltage to supply control signals to the computer circuitry in response to the first and second AC transistory signals.

Abstract: To secure a cylinder core (7) of a locking cylinder (3) against being pulled out of the locking-cylinder housing (5) by force, there are proposed retaining pins (41) which are seated in bores (43) of the cylinder core (7) and which are prestressed by springs (45) into, for example, sickle-shaped grooves (47) of the receiving bore (13) of the locking-cylinder housing (5). The retaining pins (41) each have, at their end engaging into the groove (47), a knife-edge cone (51) which widens towards the groove (47) and which, during an attempt to pull the cylinder core (7) forcibly out of the locking-cylinder housing (5), prevents the retaining pin (41) from sliding back into its bore (42). Retaining pins (41) of the foregoing type require only a comparatively small amount of space in the cylinder core (7) which is consequently not needlessly weakened. Furthermore, sufficient constructional space for accommodating additional blocking pins (33) or the like remains in the cylinder core (7). <IMAGE>

Abstract: A method, and a computer program system for performing the method, enhances the transfer of data streams between application programs and communications programs in telecommunications systems. The enhancer system is interposed between a host computer network communications program, such as VTAM, and the application program being used for accommodating data transfer requests from end users in the VTAM environment. The enhancer system intercepts data RECEIVE requests from the application program to the communications program. A corresponding receive-accepted data signal is relayed to the application program, thereby allowing that program to continue execution without awaiting a response to its RECEIVE request. The enhancer system interacts with the communications program to realize the transfer of requested data therefrom when it becomes available. The requested data is subsequently transferred to the application program by interrupting the normal operation thereof and causing the program to generate appropriate RECEIVE requests responsive to which the sequential transfer of requested data occurs.

Abstract: An apparatus in which a latent image is developed with marking particles. The marking particles (50) are transported to the latent image by a donor roller (30). As the marking particles are being moved to the latent image, they are electrically charged by a blade (36) in contact with the donor roller. An AC potential is applied on the blade. The AC potential is operator adjustable to change the charge on the toner particles. This corrects for changes in the environment and permits the slope of the tone reproduction curve to be optimized for the latent image being developed.
