Title: Fluxless dolder coating apparatus
IPC: B23K3/06
Filed: 1972-09-02
Abstract: 1437000 Soldering LUCAS ELECTRICAL CO Ltd 20 Aug 1973 [2 Sept 1972] 40797/72 Heading B3R [Also in Division C7] Fluxless solder-coating apparatus comprises a reservoir 11 for molten solder, a chamber 15 extending towards the bottom of the reservoir, means for supplying a reducing gas to the chamber, means for supporting a component within the chamber, an orifice 17 in the bottom of the chamber and a valve member 22 cooperating with the orifice so that in use molten solder from the bottom of the reservoir can flow into the chamber for application to the component supported therein. The reservoir 11 is surrounded by heating elements 13 to maintain solder 12 molten and the chamber, formed by a vessel 15, extends into the reservoir with the orifice 17 normally closed by tapered member 22 carried on the bottom of the reservoir. The top of the vessel 15 has a flange 18 which is slidable on pillars 19 with springs 21 urging the vessel downwardly and cams provided for acting on the flange to raise the vessel. A sealing lid 23 closed the upper end of the vessel and slidably carries a rod 26 supporting a titanium carrier 28 and a gas inlet conduit 29 and an outlet conduit 31 are connected to the vessel. In use a semiconductor wafer 32 is loaded into the carrier 28 and the lid supporting the carrier assembly is placed on the vessel and the lid clamped in place with the carrier in a raised position. Nitrogen is fed into the vessel to remove oxygen and is followed by hydrogen, the vessel is then raised to allow solder to flow into the vessel until the levels in the reservoir and vessel are the same. Then the rod 24 is pushed down to lower the carrier and wafer into the solder where it is held for 6 seconds. After withdrawing the wafer the hydrogen is replaced with nitrogen at a pressure sufficient to displace the solder from the vessel. A plurality of wafers may be simultaneously treated. In a modification the wafer is held fixed below the level of the solder in the reservoir and in use the solder is allowed to flow into and out of the vessel at a controlled rate.

Abstract: 1,151,603. Endless conveyers. MOBA A.G. 15 Sept., 1966 [16 Sept., 1965], No. 41308/66. Heading B8A. [Also in Division G1] A row of eggs is transferred simultaneously from a respective row of rollers 3 of an endless conveyer 2, to a series of vertically disposed grippers 47 (one only, shown) of weighing devices 48, by the action of a series of grippers 15 (one only shown) carried by an endless chain 14. The rollers 3 drop the eggs into respective cups 5 carried by a shaft 4. The latter is reciprocated and simultaneously twisted so as to drop each egg on to a lower bifurcated member 29 of the respective gripper 15. The gripper is tilted over into a receiving position by the action of a follower 19 which engages a fixed cam 20. A follower 41 on an arm 40 of the gripper 15 (Fig. 6) then engages a cam 44 so as to raise the gripper member 29 to grip the egg against the upper gripper member 28 (Fig. 6). The grippers 15 are then carried round to the grippers 47. A follower 42 on each gripper 15 engages a cam 45 thereby rotating the whole gripper assembly through 90 degrees. A part 49 of the arm 40 then engages an abutment 50 to cause release of the gripper 15 and consequent transfer of the egg to the gripper 47.

Abstract: 413,373. Calculating - apparatus. PETTERS, Ltd., and PETTER, G. B., Westland Works, Yeovil, Somerset. Jan. 20, 1933, No. 1982. [Class 106 (i).] Zeroizing-mechanism.-The totalizer pinions of a calculating-machine are zeroized by moving them forward positively to the zero position by means of toothed sectors adapted to cooperate with star wheels on the totalizer pinions, the star wheels being restrained from further movement when in the zero position by the toothed segments. The invention is shown applied to a key-set and operated machine of the type described in Specifications 360,375,. 360,376, 360,377, and 408,633. The pinions 3, Figs. 1, and 2, of the numeral wheels are each associated with a transfer cam 4 and a star wheel 6 which co-operate respectively with a transfer lever 5 and zeroizing sector 7. A set of detents 3a prevents actuation of the pinions in an anti-clockwise direction. The star wheels and toothed sectors are so shaped that in the zero position of the pinions the sectors can move idly past. As shown the star wheel has three teeth 10, 11, 12 with spaces of 108‹, 108‹, and 144‹. The sectors have square teeth and they are oscillated by a transverse rail 9 operatively connected to the zeroizing handle, a yielding connection being provided by a spring 15. Incomplete movement of the zeroizing handle will prevent return of the sectors so that the pinions will be locked against movement. To render the transfer mechanism inoperative during the zeroizing operation the transfer pawls 17 that are carried on the transfer levers 5 and the transfer levers themselves are each provided with a tail 24, 23 which project into the path of a transverse rail 25 connected by a link 26 to the arm 27 of the rail 9.
