Title: Control method and apparatus for continuously variable transmissions
Inventor: TAYLOR DANNY R
IPC: F16H63/46
Filed: 1990-08-13
Abstract: A control system for continuously variable transmissions is operative in a number of functional modes. A "neutral mode" fully disengages a clutch and sets a variable ratio to an extreme low ratio when a gear shift is in a neutral position. A "hold mode" slightly engages the clutch to cause a finite amount of vehicle creep when the gear shift is in a forward or reverse position and a throttle is fully released. A "normal start mode" partially engages the clutch when the gear shift is in a forward or reverse position and the throttle is depressed. A "drive mode" fully engages the clutch and sets the variable ratio to maintain a predetermined engine speed when the vehicle is travelling at greater than a predetermined minimum vehicle speed and the clutch is slipping at less than a predetermined amount of clutch slip.

Abstract: To aerate liquids or to wash gases, these should be dispersed to a large surface area. For this purpose a for example  cylindrical hollow body (1), having an aeratable hollow space (2) passing axially through its length, is provided internally and externally with a porous jacket (1), filled with a packing (4) and allowed to rotate just under half immersed in the liquid. To prevent for example air being forced to circulate in the hollow body, at least one longitudinal wall (3) is incorporated, which preferably extends from the external jacket to the internal jacket (1). Pressure aeration or deaeration of the hollow body can also be provided. Additional scoop devices (5) around the hollow body can pour liquid over the latter during the rotation. The above considerations also apply to immersed discs, in such a way that between each pair of neighbouring discs (7) a sealing strip (6) and also an axial hollow space (8) are provided, ventilation of said hollow space further improving the general aeration effect. An additional improvement in efficiency is obtained by blowing air between the discs. Instead of air oxygen-enriched air, oxygen or a gas to be washed may be used. <IMAGE>

Abstract: The present invention relates to a device for indicating a leak in a flat roof, with a pair of electric measuring leads (1, 2) which are at a close distance apart and are insulated from one another in the dry state, in which arrangement, however, water penetrating between the measuring leads (1, 2) produces an electrically conductive connection between the measuring leads, and a device (10) is provided for measuring the resistance of at least one measuring lead along its length up to the moisture bridge. In order to develop a system of this type in such a way that the measuring reliability is increased and faulty readings are avoided while maintaining the accuracy of the leakage detection, it is proposed according to the invention that at least one further measuring lead (3) be provided at a close distance from the two first measuring leads (1, 2), which further measuring lead (3) is insulated in the dry state and in the wet state is connected in an electrically conductive manner to one of the two first measuring leads (1, 2) and/or to a fourth lead (4), and that the third lead (3) be connected to an alarm device (20) which is designed in such a way that it transmits a signal if the third lead is connected in an electrically conductive manner to one of the two first measuring leads (1 or 2) and/or to the fourth lead (4). <IMAGE>

In the system, a more complete ensemble definition permits a more accurate ensemble time to be calculated. The system takes into account at least weighted time and weighted frequency aspects or weighted time and weighted frequency aging aspects of each oscillator in the ensemble. Preferably, the system takes into account all of the weighted time aspects, weighted frequency aspect, and weighted frequency aging aspects for each oscillator in the ensemble. The weights with respect to each clock can be chosen to be either zero or any positive value such that the sum of the weights for each aspect sum to one. The system can be implemented using a Kalman approach.

Abstract: An assay tray assembly and an assay tray primarily for chromatographic analysis has a plastics moulded test tray 1 mounted on a plastics moulded collection tray 72. The test tray has a spaced array of chambers 3 disposed as per a microtiter plate. Each chamber has a bottom outlet port 5 formed by a flange 8 which retains within the chamber a chromatographic medium to which test liquid deposited in the chamber is to be subjected for the percolate or eluate liquid to emerge from the respective outlet ports. The collection tray 72 has a spaced array of wells 16 disposed as per a microtiter plate to correspond with the chambers 3 and the tray 1 is mounted on the tray 72 for each chamber to communicate with a corresponding well 16. Each chamber 3 has a tubular spigot part 12 which extends into the respective well 16 to alleviate cross contamination of the liquid derived from the outlet ports 5. The depth of entry of the tubular spigots 12 into their respective wells 16 is restricted by abutment between the bottom of the test tray with the top of the collection tray. The volume of each well 16 beneath the tubular spigot it receives is adequate to accommodate all of the eluate or percolate derived from the chamber 3 with which it communicates to alleviate liquid on the spigot parts from dripping into wells with which those tubular spigots are not associated (and thereby cause cross contamination) when the trays are separated for analysis of the percolate or eluate.

Abstract: An integrated circuit having a normal operating mode and a special operating mode, such as a special test mode, is disclosed. The special test mode is enabled by a series of signals, such as overvoltage excursions at a terminal, rather than by a single such excursion, so that it is less likely that the special test mode is entered inadvertently, such as due to noise or power-down and power-up of the device. The circuit for enabling the test mode includes a series of D-type flip-flops, each of which are clocked upon detection of the overvoltage condition together with a particular logic level applied at another terminal; multiple series of flip-flops may be provided for multiple special test modes. Additional features include the provision of a power-on reset circuit which locks out the entry into the test mode during power-up of the device. Acknowledgment of the entry into test mode is provided by the presentation of a low impedance at output terminals while the device is not enabled; chip enable of the device causes the device to exit the test mode. Once in test mode, the output enable terminal of the device can provide a chip enable function.

Abstract: A battery including a sealing member 10 for sealing an opening 7 of a battery housing 1, a current collecting pin 5 press-fitted in a through hole 11 formed through the sealing member 10, and a reinforcing member 20 for reinforcing the sealing member 10. The reinforcing member 20 is constituted of a thick-walled portion 21 for covering an outer circumferential surface of a cylindrical portion 12 of the sealing member 10 forming the through hole 11 and a disk portion 22 extending radially outwardly from the thick-walled portion 21. A space 8 is defined between the sealing member 10 and the reinforcing member 20, and a thin-walled portion 13 for preventing an increase in internal pressure in the battery housing 1 is formed in the sealing member 10 at a position opposed to the space 8. The sealing member 10 is reinforced by the thick-walled portion 21 to thereby prevent generation of cracks in the sealing member 10 and electrolyte leakage accompanied thereby. Further, when the internal pressure increases, the thin walled portion 13 is reliably broken to suppress the increase in the internal pressure.
