Abstract: A utensil dispenser comprises a housing, a utensil support assembly and a utensil dispensing actuator. The utensil support assembly comprises a skewer for retaining a stack of utensils to be dispensed. The actuator provides for sequential dispensing of the utensils. The utensils are held in alignment on the skewer until they are sequentially dispensed. Dispensing occurs as the utensils are individually removed by the actuator from the skewer where the utensil falls by gravity to an opening at the bottom of the housing for presentation to a user. A retainer member keeps the utensils stored on the skewer until the utensil support assembly is mounted in the housing and the utensils are ready for dispensing.

Abstract: Pickup device (24) is for mounting on the mounting plate of a positioning robot. The pickup device has a frame (30) which carries movable carriages (36, 38). Cam ring (50) controls the position of the carriages. Downwardly depending arms (60, 62) carry pairs of levers thereon. The levers have facing sloped cam surfaces (84, 86) which are spread by downward thrust of closing pin 88. When the closing pin drops too far, it indicates lack of grasp and this is signaled by contacts (114, 116).

Abstract: U-shaped heater (42) carries busses (22, 24) which are electrically connected to supply heating power. Heated tip (58) is secured to the front of the heater and is as wide as is necessary to at the same time reach all of the leads to be soldered. The heater and busses rock on a pivot provided by pin (18) close to the heated tip so that rocking causes little lateral dfisplacement. Rocking in the single plane is limited by the busses engaging on the back of body (12) and the thermocouple connector body engaging on the front of the body, both in sliding engagement. Spring (62) holds the movable parts on the pivot pin and centers the heater.

Abstract: Heater bar assembly for a reflow solder machine comprises first and second fingers (50, 52) carrying U-shaped heater bar (54) which is pivotable on main member 22. A spring urges the heater bar assembly to the centered position. First and second thermocouples (82, 84) are secured to the heater bar (54) and are connected through a transfer switch (104) by which their electrical connections can be alternated. One controls the power supply and the other cuts off the power supply if temperature exceeds the selected temperature.
