Abstract: A latch is provided with a rotary solenoid having an eccentrically mounted drive pin for driving a latch hub dogging means. The solenoid assembly can be easily demounted, rotated 180.degree., and remounted in the latch housing so that the drive pin can be made to drive the dogging blade either in or out of the latch hub dogging slot, depending on its mounted position. By this structure, the electric control may be readily converted from "fail-lock" to "fail-unlock" or vice-versa.

Abstract: A valve position monitoring and control system incorporates a proximity sensor positioned near a movable valve element to detect the operational position of the valve and includes circuit means coupled to a valve actuating solenoid for deactivating the solenoid in the event the valve fails to respond to command signals for positioning the valve in a predetermined position. In one embodiment, the system incorporates a pair of series connected valves used in presses which valves in turn are operated by solenoid actuated pilot valves. In the event either one of the valves do not operate either by opening within a predetermined time after actuation or closing within a predetermined time after their deactuation, the system of the present invention will not permit further operation of the valves until the system has been manually reset.

Abstract: An electric single-pass drip-type coffeemaker includes a plastic base having an upper half with an opening surrounded by a downward lip. A metal warming plate closes the opening and is laterally immobilized by downwardly projecting spaced bosses around the opening. A central upward protuberance on the lower half of the base terminates in a high temperature silicone pad which engages the underside of the warming plate and presses the plate up against a gasket seated in a groove in the lip to vertically immobilize the warming plate between the lip and the silicone pad when the upper and lower base halves are secured together. A U-shaped metallic extrusion is welded or soldered to the underside of the warming plate and includes an upper passage containing an electric heating element controlled by an adjustable thermostat secured to the extrusion and a lower water heating passage connected to the cold water reservoir and hot water discharge spout of the coffeemaker.

Abstract: A machine for inserting tire valves on wheel rims designed for receiving tubeless tires comprises pneumatic, electrical and/or electronic apparatus for logically programming a rim conveyor, apparatus for detaching a single rim and successively positioning same in waiting, operative and discharge positions, apparatus for exerting a pressure against the detached rim in the operative position for engagement with a rotary drive, apparatus for rotating the rim, apparatus for detecting the valve hole in relation to an axis ZZ of the emitting and receiving elements of a detection cell, apparatus for positioning the valve hole on an axis YY common to a centering spindle and to a cylinder carrying the valve to be inserted into the valve hole, apparatus for selecting a valve for each rim, apparatus for positioning the valve into the rim hole, and apparatus for holding the rim during the valve positioning operation.

Abstract: A musical door chime which includes a repertoire of musical tunes one of which is played when a door pushbutton, preferably the front door pushbutton, is actuated. The musical tune which is played may be selected by means of a keyboard connected to a microprocessor. Digitally encoded representations of the notes of each musical tune are stored in a memory. Each digitally encoded musical note is read from memory by the microprocessor and converted by the microprocessor into a squarewave having the frequency and the duration of the note. The microprocessor is connected to a note strike and decay circuit which is preferably connected in series with an active audio filter circuit for translating the squarewave into a sinusoidal output for energizing a loudspeaker so that relatively high quality audible tones are heard when the musical tune is played.

Abstract: Push rod of panic-type latching device contains a fusible section which melts in the event of a hot fire so that the temperature will not cause elongation of push rod to disengage upper door latch.

Abstract: A kitchen mixer having a centrifugal speed control in which a control contact is positioned by a follower engaging a cam linked to a rotatable speed-selector knob. The cam has two levels so that by pressing the cam downward by means of a button on the outside of the mixer housing the follower engages second level and shifts contact to increase the mixer speed.

Abstract: For locking an object to a stationary structure, a securing device comprising an ordinary padlock, a C-shaped housing embracing the body of the padlock, the top of the housing being apertured to receive the shackle of the padlock, and fastening means to hold the housing to the structure.

Abstract: Sewing machine is modified to include means for feeding and cutting off slide fastener ladder as it is sewn directly to fabric. The means for feeding and cutting off include a pair of parallel blades one of which, the feed blade, is loosely mounted and biased downwardly so that when the assembly is depressed all the way forward, blade yields and cutter severs the ladder. Cam means are provided to drive the assembly in a rectangular path to engage the ladder element-by-element, pulling it through the sewing station. Override means are provided to momentarily stop the back-and-forth movement of the assembly and a depressor simultaneously urges the assembly down to accomplish the aforesaid severing.

Abstract: Door closer of the type which holds the door open until an associated electric circuit is opened or closed. Provides means for free swinging of the door when the door closer is "cocked". This is achieved by a drive plate interposed between the closer shaft and its operator arm. The plate provides a pair of apertures which may selectively retain a pin adapted to work against the closer arm.

Abstract: Door holder is adapted to work with conventional door closer. Holder comprises a shoe moving along a track and connected to the closer operating arm. A latch, when device is activated, holds shoe with door in open condition. Latch is attached to a frame near the track and which may be moved away from latching engagement with shoe either by forcible closing of the door manually or by de-activating closer.

Abstract: A strip for a stringer of a sliding fastener which is constituted by a row of successive discrete transverse strip elements which are interconnected at their opposite ends by two longitudinally extending cords, each element having an enlarged central portion and opposed leg portions with enlargements at their ends through which the cords pass and are embedded. The strip is bent to a U-shape and stitched to a mounting tape.
