Abstract: 807,486. Reciprocating pumps. GENERAL ANILINE & FILM CORPORATION. Nov. 20, 1956 [Dec. 8, 1955], No. 35508/56. Class 102(1). [Also in Group XX] A pump for dispensing discrete amounts of liquid from a storage tank to an apparatus which comprises a variable speed motor, is operated by a lever the stroke of which determines the amount of liquid supplied, and the stroke of the lever is varied by a first control which simultaneously varies the speed of said motor, and by a second control means independent of the first. As shown in Fig. 1, the lever 12 is pivoted at 13 and is reciprocated regularly against the action of spring 27 by a cam 26 driven by a motor 24. The lever depresses a button 9 of the diaphragm pump 7 at each stroke, the extent of the depression determining the amount of liquid delivered. The drive motor for the associated apparatus (not shown) is electric, and its speed is varied by a resistance 29 operated by a knob 31. The knob 31 simultaneously operates a variable cam face 34 which arrests the lever 12 and limits its effective stroke. The stroke of the lever is also variable by a second and independent control means comprising knob 19 and screw thread 17 which works in a block 15 which carries the pivot 13. Knob 19 thus affects the stroke of lever 12 by varying the position of its pivot 13.

Abstract: 1,134,349. Toy gun. G. FERRI and J. MARINAI. 12 Aug., 1966 [18 Aug., 1965], No. 36153/66. Heading A6S. A cap-strip firing gun whereby on detonation of the cap a previously exploded cap is sheared off the strip and ejected, and wherein said capstrip is housed in a guide which is movable in the portion adjacent to the shearing zone, such movement being between the shearing- blade and firing pin, both fixed, and a movable percussion body, movement of the latter against the guide causing its movement against the firing pin and shearing blade thus causing cap detonation and shearing of a previously detonated cap. The firing mechanism of such a gun is illustrated in Figures 2 and 3. The percussion body 17 is. forced back against the spring 19 by movement of the trigger 21. Further movement of the trigger would release the percussion body which would move to and with the guide 11 which is pivoted about the pin 12. Such a movement would force the cap C 1  against the firing pin 7a causing detonation. Simultaneously a previously exploded cap would be sheared off of the strip by the blade 7b, said cap being then ejected from the gun. Upward movement of the cap strip is controlled by the tooth 27a of the element 27, to the tooth penetrating through the slot 14 of the guide 11. Such upward movement is controlled by the firing trigger movement, element 27 being linked at 26 to the trigger arm 21a, see Figure 3. On the return trigger movement, the inclined corner of 27a is deflected outwardly by the shape of the tooth of the cap strip until it assumes its original position.
