[Also in Division F2] Apparatus for lubricating the dies of a pressure die-casting machine comprises a ram 10 carrying a lubricating head 14, means to cause forward travel and retraction of the ram, a sensor responsive to the extent of forward travel of the ram, and means for remotely controlling the extent of forward travel. The ram is operated by an air cylinder 12, to which air is admitted selectively above or below the ram piston by a valve controlled by solenoids 22, 24. Banks of micro-switches 44, 46, 48 operated by a cam 60 on the ram control both the solenoid 24 initiating retraction of the ram and a further solenoid 72 initiating the spraying of lubricant, such as graphite in an air current, from nozzles 15.

Abstract: 771,761. Making bags. DICKINSON & CO., Ltd., J. June 8; 1955 [March 9, 1954], No. 6838/54. Class 94(2). A method of making bags consisting of two separate walls secured by adhesive and having a double thickness closure flap comprises making the mouth slit in one bag wall before applying it to the other, adhesive having been previously applied to unite all four side edges of the bag and form above the slit, the closure flap. The method may be used to make bags as described with reference to Figs. 1-7a of Specification 754,449. In producing the bags as shown in Fig. 4 of that Specification a web 10 has the edge-joining adhesive areas applied by means 12, and a cutter 16 forms the slits 17. A second web 18 is applied to the web 10 by rolls 20 and the combined webs pass through folding means 22, rendered inoperative, to an adhesive applicator 23 applying stripes 24, 25 to the web 10, through notching means 26 for removing sectors at each end of the transverse adhesive areas to shape the top and bottom closure flaps, and through folding means 28 which double over the longitudinal edges of the webs onto the stripes 24, 25 to produce the side seams. An applicator 30 applies areas 31 of self-sealing adhesive to the closure flap and adjacent bag wall, and the webs pass through a dryer 32 to a cutter 35 which separates the bags. An adhesive stripe 38 is applied by an applicator 36, and the bottom closure flap 37 folded onto it by means 39. The completed bags are conveyed to stacking means 9. In forming a further type of bag, Fig. 2, the apparatus is modified in that the means 22 are rendered operative to fold the edges of the wider web 10 over those of the narrower web 18, and the devices 23, 26, 28 are rendered inoperative. One web, preferably 18, may be transparent and the other opaque or semi-opaque. The web 10 may be slit into bag lengths before being applied to the web 18 or may be replaced by a stack of separate bag blanks. If the material of the web 10 is resistant to the application of' self-sealing adhesive, a preliminary coating of gum may be applied by means 5 and dried by a dryer 6 prior to the application of the adhesive areas 31.

Convention date, March 12, 1930. [Class 106 (iii).] A periodic-counter type speedometer is constructed so as to avoid backlash at the initial position of the measuring wheel and comprises a measuring wheel 16 driven by the pinion 15 mounted on the toothed wheel 13 rotated by the fine toothed wheel 10 having secured to it the toothed wheel 9 which is rotated by the toothed wheel 12 driven from the rotating shaft the speed of which is required and which is mounted on the lever 7 to be periodically disengaged from the wheel 13 through the lever 7 periodically engaging a cam 4 on the spindle 1 time-driven by gear wheels 2, 3 from a main spring. The spindle 1 has also fixed to it a cam 5 which periodically actuates the lever 8 and pawl 25 to control the looking of the wheel 13 and thus the measuring wheel 16. When the wheel 10 is disengaged from the wheel 13 and the wheel 13 is unlocked, the wheel 13 and measuring wheel 16 return to an initial position under the action of the spring 17 and backlash is avoided by that initial position being defined by a blank part 18 in the toothed rim of the measuring wheel 16 contacting with the teeth of the pinion 15 to prevent further motion. The rotation of the measuring wheel is transmitted to a pointer spindle 23 through pins 19, 20 and gear wheels 21, 22 which are returned to an initial position by the spiral spring 24. It is stated that the mechanism described stabilizes the pointer without the use of a stabilizing device which affects the accuracy of the instrument.
