Title: Contact status monitor
Inventor: WAGGAMON DENNIS W
IPC: H01H47/00
Filed: 1993-03-31
Granted: 1998-08-11
Abstract: A circuit  which  gives  a  continuous  voltage  output indication of whether a contact is open or closed.   The circuit senses the voltage across the contact to detect whether the contact is open or closed.   When there is a significant voltage, the circuit indicates that the contact is  open.   When  the voltage  is  negligible,  the  circuit indicates that the contact is closed. Alternatively, the current through the contact can be sensed to provide an indication of whether the contact is conducting or not.  The circuit can be used to indicate welding closed of a relay contact in which case power to the load can be turned off or the contact can be opened by other than normal means.  One application is to discontinue closing movement of a garage door when the motor relay switch does not open as desired, but there are innumerable other applications.

Title: Programming response to electronically-controlled gauges
Inventor: DANNENBERG ROBERT D
IPC: G01R7/06
Filed: 1994-03-21
Granted: 2003-09-16
Abstract: Rather than using the viscosity of dampening oil to establish the speed at which the movement of an air care instrument gauge moves, the speed is defined by programming speed data into memory of a microprocessor that controls the movement. When the microprocessor receives an input signal commanding the movement to move, it develops an output signal for operating the movement that is based both on the input signal and on the stored speed signal. The stored speed signal is used by the microprocessor as weight for a software filter used in development of the output signal.

Title: Floral grouping wrapper having a detachable portion
Inventor: WEDER DONALD E
IPC: A01G9/02

Granted: 1999-11-02
Abstract: A method for wrapping a wrapper about a floral grouping wherein the wrapper is a sleeve or sheet of material having a cinching tab or strip of bonding material or both and a detaching means such as perforations for detaching a portion of the sleeve or sheet of material. The floral grouping is placed on the sheet of material which is wrapped thereabout, or the floral grouping is disposed in the interior space of the sleeve. The cinching tab is attached near one end of the sheet or sleeve. The cinching tab has a bonding material disposed thereon which, when the cinching tab is pulled tightly about the wrapper, causes the wrapper to be crimped and tightly bound about the stems of the floral grouping. When a sheet or sleeve having a strip of bonding material is used, the portion of the wrapper having the strip of bonding material is crimped manually or automatically about a portion of the stems of the floral grouping causing portions of the wrapper to overlap and bond to each other causing the wrapper to be held firmly about the stems of the floral grouping. The wrapper may further comprise an additional strip of bonding material for bonding an informational card or label to the wrapper. After the wrapper is wrapped about the floral grouping, a portion of the wrapper may be removed by using the detaching means, thereby leaving a portion of the wrapper wrapped or bound about the floral grouping.

Abstract: Cooling water pumped by a cooling-water pump is passed via a cooling-water supply passage, a cooling-water dispensing chamber, two upper and lower through-holes and a water jacket, a thermo-valve and discharge  via a cooling-water discharge passage 33.  When the amount of cooling water supplied from the cooling-water pump is excessive, or when the thermo-valve has been closed, a relief valve mounted in a bypass passage which connects the cooling-water supply passage and the cooling-water discharge passage is opened, thereby permitting the cooling water to be diverted.  The bypass passage diverges from the cooling-water supply passage upstream of the cooling-water dispensing chamber and hence, even if the relief valve is opened, the flow pattern of the cooling water flowing within the cooling-water dispensing chamber is not influenced, and the flow rates of the cooling water passed through the two through-holes cannot be unbalanced.

Abstract: A seat track apparatus of a vehicle for retaining a slide member between a lower seat track and an upper seat track of the seat track apparatus. The seat track apparatus provides a channel in the lower seat track having at least one longitudinally extending contact surface. The slide member has a shape complementary to the channel and is disposed within the channel with at least one contact surface in contact with the contact surface of the channel. The slide member provides a plurality of cylindrical pins projecting outward from the side wall of the slide member and extending through apertures in the side wall of the lower seat track. The engagement of the pins by the lower seat track aligns and restricts movement of the slide member in the plane in which the cylindrical pins extend therethrough. In a preferred embodiment, the slide member provides outwardly projections on the bottom wall of the slide member. Apertures provided in the bottom wall of the lower seat track receive the projections extending from the bottom wall of the slide member to maintain contact between the contact surface of the slide and the channel. In a second embodiment, the bottom wall of the lower seat track has a plurality of punched lanced upsets which abut the bottom wall of the slide member and prevent the bottom wall of the slide member from moving away from the channel thus maintaining contact between the contact surfaces of the slide member and the channel.
