Abstract: 415,586. Date indicators. JEPSEN, H. J., 191, Strandvej, Hellerup, near Copenhagen, and NIELSEN, K. C., 25, Kastelsvej, Copenhagen. Aug. 28, 1933, No. 23951. Convention date, Oct. 20, 1932. [Class 106 (iv).] In a " savings Calendar " wherein date-bearing drums 20-22, Fig. 1, are stepped forward automatically by the daily insertion of one or more coins, actuation is effected by the rocking of a longitudinal shaft 26, Fig. 10, carrying an arm 77 which co-operates with a slotted wheel 74 to vary the operation of the date indicator in accordance with the number of days in the month. Secured to the shaft 26 is an arm 59, Fig. 7, carrying a pawl 69 which actuates a 31-toothed ratchet wheel 68 secured to the " date " drum 21, a cam slot 70 in the pawl co-operating with a pin 63 to ensure that the wheel 68 is stepped on by one tooth only, independently of the angle through which the shaft 26 rocks. This angle is varied from month to month by the engagement of the arm 77 with the wheel 74, which is carried by the "month" drum 22 and divided into twelve sectors of different radii corresponding to the numbers of days in each month, so that the shaft 26 will move through a greater angle each day in a 30-day month than in a 31-day month, and a greater angle still during February. After the actuation on the thirtieth of a 30-day month, the shaft 26 will rock back sufficiently for a spring-pressed auxiliary pawl 81 on the pawl 69 to engage a pin 78 on the ratchet 68, so that on the following day the pawl 81 will pull the drum 21 through two steps and bring it round to the "1st"; the same thing will happen on the 28th of February owing to the greater angle of swing of the shaft 26, and on the 1st March the drum 21 will be moved through four steps. To allow for leap year, a pin 91 on the wheel 74 actuates a four-toothed star wheel 89, so that every fourth year a pin 90 thereon raises a pivoted arm 85 to act as an abutment for the arm 77 and prevent it from engaging the sector 76 corresponding with February, giving this month 29 days. The " day " drum 20 is operated by mechanism similar to that for the drum 21 except that the auxiliary pawl 80 and pin 78 are omitted. The "month" drum 22 is actuated by the engagement of a toothed wheel 100, Fig. 10, by a spring-controlled pawl operated once a month by a cam 94 carried by the " date " drum 21.

Abstract: 894,570. Photo-electric flaws detection. BRITISH IRON & STEEL RESEARCH ASSOCIATION. Oct. 17, 1960 [July 15, 1959], No. 24300/59. Class 40(3). In order to detect flaws and the like in a moving surface, e.g. of tinplate, light is directed in a narrow beam having its axis transverse to the direction of motion of the surface, and variations in the diffusely reflected light, or in both the diffusely and the specularly reflected light, are detected to indicate the presence of a flaw. The narrow beam is produced by a lamp 1 and lens system which is mounted in a cabinet such that associated photo-cells 3 receive only light diffusely reflected from the surface 2 being inspected, Fig. 1, the photo-cells being mounted in one or more rows parallel to the beam axis. Further photo-cells may be provided to receive the specularly reflected light. In Fig. 2, each photo-cell 3, which receives diffusely reflected light, feeds an amplifier 7 and discriminator 8, which gives an output only if the cell output exceeds a certain value. The discriminator outputs are combined, integrated at 9, and passed to a second discriminator 10 which operates a relay 11, the relay in turn actuating a sorting device, strip marker, counter, display or recording device. In a second embodiment, Fig. 4 (not shown), the cell outputs are sequentially sampled, sampling taking place at such a speed that no part of the surface under test is not inspected. A ferrite core sampling circuit is described with reference to Fig. 5 (not shown). The discriminators may be devised to give outputs corresponding to several ranges of cell output, Fig. 6 (not shown). In a further embodiment, the outputs of cells responding to the specularly and the diffusely reflected light are compared to represent surface finish.
