Filed: 1990-01-16
Abstract: WORM DRIVE CLAMP WITH AUTOMATIC SPRING LEVER ACTION     ABSTRACT          A worm drive clamp comprising a flexible metal band having a housing secured to a connecting portion thereof.    A worm screw,  having a spiral thread,   is supported for axial rotation in the housing adjacent a side of the band connecting portion.   The worm screw has its rotational axis co-extending with the longitudinal axis of the metal band.    A resilient leaf spring is secured to the side of the band adjacent the worm screw for biasing the free end portion of the band positioned thereover against the screw when the band is tightened about an object.    The free end portion of the band is provided with spaced-apart screw thread engaging teeth or slots along a length thereof to engage with the spiral thread of the worm screw.   The housing is also provided with an inlet and an oulet port for the passage of the free end of the band through the housing.    The leaf spring has a flexible connection to permit the band to be slidingly  displaced  adjacent  the  worm  screw  without arresting threaded engagement between the spiral thread of the worm screw and the thread engaging teeth provided in the free end portion of the band.   When the band is tightened about the object the spring urges the free end portion of the band to enter into threaded engagement with the worm screw.

IPC: G11B27/34
Filed: 1990-02-09
Abstract: A recording and/or reproducing method and corresponding apparatus are provided, in which in phase monaural audio signals are separately mixed with a clock signal and a data signal, which are opposite in phase to each other, and the mixed signals are recorded in separate channels on a recording medium. Upon reproduction and recombination of the signals recorded in the two channels, the clock signal and the data signal cancel each other out so that the listener hears only the combined monaural audio signals but the clock signal and the data signal can be separated from the reproduced two channel recorded signals prior to their recombination and be used to generate visual display data concerning the recorded signals.

IPC: C02F9/00
Filed: 1990-07-30
Abstract: A system for on-site recovery of reusable industrial waste components, such as solvents, from a liquid waste stream includes a trailer that is internally partitioned to separate system components through which the waste stream passes in a first partitioned section of the trailer from support and control components in the second trailer section. Input waste is fed into a horizontal thin-film evaporator within the first trailer section, while steam is fed in a closed loop through the evaporator from the second section of the trailer for evaporating volatile solvents in the waste stream, and thereby separating the volatile solvents from non-volatile liquid and solid components of the waste stream. The evaporated volatile solvents are fed to a heat exchanger, again enclosed within the first partitioned section of the trailer, for recondensation through heat exchange with a coolant fed to the heat exchanger in a closed loop from the second trailer section. The recondensed solvents are then fed to a water separator tank and a molecular sieve for separation of immiscible and miscible water from the solvents, and thence to a holding tank for resupply to the customer. The non-volatile components of the evaporator output are fed to a second holding tank for recirculation through the evaporator or return to the customer for disposal.
