A vacuum switch for interchangeably connecting a plurality of vacuum lines includes a vacuum housing having a plurality of ports to which the vacuum lines are connectable. The vacuum housing has a plurality of channels molded in one surface of a plate and communicating with the ports. Each channel has at least one passage through the plate to the opposite surface. The channels are arranged to provide the desired fluidic logic. A one-piece seal member seals the channels to maintain a vacuum therein. A plurality of valves are slidable upon the surface of the plate opposite the channels. Each valve has a cavity providing fluid communication between passages when the cavity spans a pair of passages. Electrical contacts, movable with the valves, activate a circuit to provide an electrical signal corresponding to the desired mode selected for the vaccuum lines.

An actuator for use in the nature of a servomotor, having means for providing a signal indicative of the position of a mechanical linkage member. A feedback signal source voltage is alternately connected to a feedback signal lead by switch means which are carried by the mechanical linkage member of the actuator. Variable resistance means can be inserted between the voltage source and the feedback signal lead to provide a plurality of feedback signal voltages, each of which indicates a different position of the actuator linkage member.

An actuator for use with vehicle door locks or the like includes a housing and an electric motor positioned in the housing. A shaft is journaled in the housing and extends outwardly therefrom with an actuator member being attached to the shaft outside of the housing. A drive connection between the motor and the shaft includes a second shaft journaled in the housing and a dual gear rotatable with the second shaft. The dual gear is in driving relationship with the first shaft and with the electric motor through a bevel gear freely mounted on the first shaft.

An electrically driven linear actuator has a housing with a plurality of bus bars mounted within the housing. An electric motor is positioned in the housing and is in driving relationship with a linearly movable actuator member. The actuator member carries a contact which moves along and in contact with the bus bars. There is an electrical connection between the bus bars and the motor with the flow of current through this connection being controlled by the movable contact.

A seed monitor for a multiple station planter includes a light source adjacent each seed path and a pair of phototransistors positioned in alignment with each light source. The phototransistors for each seed path are connected to pulse generating means, each of which provide a constant width pulse in response to an interruption in light received by a phototransistor from its light source. An OR gate is connected to the pulse generating means so as to provide an output signal whenever there is a pulse at one of its inputs. The light sources for the multiple seed paths may be operated to periodically monitor each planting station.

The combination of a calculator and a telephone set and telephone tone generating means is arranged so that the calculator drives the telephone tone generators. When the telephone is activated, for example by lifting the handset, the calculator is connected to the tone generators with operation of the calculator switches driving the tone generators. A switch is provided whereby the calculator may subsequently be operated, as a calculator, while the telephone set is being used, without operating the tone generators.SUMMARY OF THE INVENTIONThe present invention relates to the combination of a calculator and a telephone set which is so connected that the calculator drives the telephone tone generators.One purpose of the invention is a combination of the type described in which the start of the telephone operation, for example lifting the handset, connects the calculator to the telephone tone generators such that the operation of the calculator switches is effective to "dial" a telephone number.Another purpose is a combination of the type described in which the calculator can be operated by itself, or as a means to operate telephone tone generators.Another purpose is a combination of the type described utilizing an OR gate matrix to connect the calculator to a series of flip flop latches which in turn drive telephone tone generators.Another purpose is a simply constructed reliably operable circuit of the type described.Other purpose will appear in the ensuing specification, drawing and claims.

A moisture activated wiper sensor has all necessary electronic and optical components for detecting moisture and performing signal processing in a single module which mounts to a vehicle windshield. The packaging of the optical components and associated electronic circuitry in an acceptably small housing is achieved by use of insert-molded lenses and infrared emitters and detectors mounted on separate printed circuit boards called wing boards. Wing board supports molded into the housing assure proper orientation of the wing boards relative to the lenses. Flexible cables connect the wing boards to a main circuit board.

An automatic coffee maker for rapid, convenient, drip-free brewing of single cups of coffee has a "flow fuse" acting in the space above a brew basket into which the output of a hot water generator passes: the fuse allows passage of small quantities of steam, but is closed by larger steam flow to force the steam to pass downward through the ground coffee, terminating the brewing process and drying the spent grounds thereafter to permit their removal and discard without drippage.

This is concerned with a switch device which is quite thin and can be used on either a flat or a contoured surface that includes a backing member which may be dimensionally stable, either as a flexible or a stiff membrane, with a flexible membrane spaced therefrom by a flexible filled adhesive material providing one or more openings so that a circuit pattern on the backing member is spaced from a conductive shorting bar on the flexible membrane such that manual or mechanical deformation of the membrane will cause electrical conduction across or between the contacted surface in the circuit pattern with deformation being provided by the flexibility of the membrane, as well as deflection or flexing of the intermediate adhesive material.

An insert molding machine has first and second mold sections, one of which is movable between open and closed positions, A slide carrying inserts is movable from an open position to a closed position wherein the slide and first and second mold sections define a mold cavity in which a part is molded. A single direction cam mechanism in the slide engages a pin in the movable mold section to releasably connect the slide and movable mold section during closure. The connection causes the slide to open upon subsequent opening of the movable mold section but allows the slide to be closed independently of the movable mold section.
