Abstract: 1,215,340. Ladder network. ANGSTROHM PRECISION Inc. 12 March, 1969 [12 March, 1968], No. 13146/69. Heading G4H. [Also in Divisions H1 and H3] A ladder network formed of two groups of resistive films 15 . . . 20 and 10 . . . 14, Fig. 1, deposited on an insulating substrate is constructed in such a manner that after manufacture the values of the films 15 . . . 20 may be adjusted individually by grinding, this grinding causing some unavoidable grinding of the films 10 . . . 14; however, the values of films 10 . . . 14 may be individually adjusted by a final grinding operation which does not at all affect the films 15 . . . 20. For analogue-digital conversion, the films 10 . . . 14 may each have a value R and the films 15 . . . 20 a value 2R. In the construction shown in Figs. 2, 3 the films 15 . . . 20 are formed by sinuous paths 31 1  . . . 31 6  and the films 10 . . . 14 by U-shaped paths 34 1  . . . 34 5 . These paths 31, 34 are constructed by depositing resistive material 72 on the walls of similarlyshaped V-section grooves formed in a ceramic substrate 30. The grooves are defined by lands. Thus the groove forming path 31, is defined by lands 50 . . . 53 and these lands are ground to adjust the resistance of path 31; similarly, lands 55 . . . 58 define the path 31 2 . However, lands 55, 58 partly define the paths 34 1 , 34 2  and thus grinding of these lands affects the resistance value of these paths. Final adjustment of the paths 34 1 , 34 2  is made by grinding lands 60, 62, respectively. Recesses 32 1  . . . 32 6  and 31 1  . . . 33 6  constituting terminals for the resistive paths are formed along the two edges of the substrate 30 and are coated with a conducting film 70, e.g. of gold. Thus the ends of path 31, make contact with terminals 32 1 , 33 1  and the ends of path 34 1  make contact with terminals 33 1 , 33 2 . The network may be encapsulated, the connections to the terminals being made through wires 36 having heads 37 contacting the film 70.

Abstract: 528,463. Feeding articles from piles. BRECKNELL, MUNRO & ROGERS (1928), Ltd., and DOLMAN, H. J. May 8, 1939, No. 13640. [Class 117] [Also in Group XVIII] The coin - freed or other actuation of delivery mechanism of articles stored in piles frees an escapement device 19, 20 to permit a spring or weight 5 to (1) raise the platform 8 supporting the pile 9 through a predetermined distance and also (2) impart a to-and-fro movement to an ejector 41 to eject the uppermost article from the pile. In the construction shown the weight 5 acts through an endless chain 4 on the platform 8, the lower chain sprocket 3 driving the shaft 18 of an escapement lever 19, 20 through a free-wheel and gearing 15. The lever has two pallets 24, 28 adapted to be engaged by lugs 25, 29 on a rocking lever 22 pivoted at 23. In the position shown the pallet 24 is engaged by the lugs 25 and the lever is locked. When a coin passes down the coin shoot (not shown) it strikes an abutment 28 on the lever 22 and rocks the latter so that the pallet 24 is released by the lug 25 but is then held by lug 29. After the coin falls clear of the lever 22 the latter is returned to its normal position by a spring 26 and the lug 29 releases the pallet 24 so that the weight 5 rotates the lever 19, 20 through approximately 180 degrees until the pallet 48 is held by lug 25. The pile of articles 9 is thus raised through the height of one article. The top-most article is delivered by the ejector 41 pivoted at 40 to a three-armed spring-loaded lever 35 connected by a link 33 to a lever 31 pivoted at 32 and operated by a coin 45 driven from the gearing 15. While the pile is being raised the ejector is retracted until its face 42 engages behind the topmost article as shown in Fig. 4; it is then moved forward and delivers the article over a guide 47. In its normal position. shown in Fig. 4, the ejector lies on top of the pile and tends to prevent fraudulent removal of the topmost article, e.g., by a wire.
