Title: Pedal board for musical instruments
Inventor: ROHDE MARK W
IPC: G10H1/34
Filed: 1991-03-12
Abstract: A pedal board for musical instruments.  Pedal mounting, guide, and electrical switch mechanisms are provided in a pedal board for an electronic organ.  Each pedal is mounted by a cylindrical pin attached to the back end of the pedal and to the base of the pedal board by an interference fit.  A similar, guide pin is attached to the front end of the pedal by an interference fit. The guide pin fits loosely in an aperture which limits lateral movement of the pin and, thence, of the pedal itself.  The lower end of the guide pin actuates an elastomeric electric switch when the pedal is pressed down.  The elastomeric electric switch is mounted on a printed circuit board, and includes a chamber having a bell-shaped wall attached to a support strip by weakened edges and enclosed at the bottom by a diaphragm carrying a conductive element.  The conductive element shorts contacts on the printed circuit board when the chamber is compressed by the guide pin.  Pedal board tension and resiliency is provided by the mounting pin or by a tension spring.

Title: Stable microemulsion disinfecting detergent composition
Inventor: JACQUET FABIENNE M
IPC: C11D10/02
Filed: 1991-09-12
Abstract: ABSTRACT OF THE DISCLOSURE:         Low viscosity and high pH disinfecting and bleaching all purpose cleaning compositions in microemulsion form, suit able in both concentrated and diluted forms for applying to surfaces to be cleaned and disinfected or sanitized, include hypochlorite, higher alcohol sulfate and higher paraffin sulfonate detergents, higher fatty acid soap, alkali metal hydroxide, liquid hydrocarbon, perfume, periodate, branched lower alcohol co-surfactant and water.  The compositions are of improved lipophilic soil removing capability when diluted with water, are of about equivalent such capability in neat or concentrated form and are of significantly better hypochlorite stability on aging at room and elevated temperatures, compared to other microemulsion cleaners that contain hypochlorite.          Their low viscosities facilitate spraying them from squeeze bottles or pump sprayers onto surfaces to be cleaned and disinfected or sanitized, such as floors and walls.  The absence of any builder salts allows uses of the compositions, especially in diluted form, to clean surfaces without the need for rinsing (wiping sufficing), and the cleaned surfaces are not objectionably streaky afterward.  The concentrated microemulsions are effective removers of mildew from bathroom tub and shower tiles, and other surfaces, but in such cases rinsing is usually desirable.  Also described are processes for the manufacture and use of the described cleaning compositions.

Title: Adaptive pressure control for an automatic transmission
Inventor: VUKOVICH WILLIAM J
IPC: B60W10/08
Filed: 1992-06-17
Abstract: An improved adaptive transmission pressure control in which cumulative adaptive corrections are stored in a multi-cell memory array, the cells being associated with specified contiguous ranges of a vehicle operating parameter, such as engine throttle position.  Periodically determined adaptive correction amounts are applied to a selected cell which includes the engine throttle setting measured at the initiation of the shift and to two or more cells associated with contiguous engine throttle ranges.  In this way, a relatively large number of cells may be employed to minimize approximation errors, while maintaining a cell-to-cell continuum of pressure correction values. In operation, an electro-hydraulic pressure regulator is controlled as a combined function of a predefined pressure command obtained from a normal table look-up and a cumulative correction amount obtained from the memory array.
