Abstract: 376,852. Clock face time-reminders. HILL, A. T., 125, Borough High Street, London. April 22, 1931, No. 11938. [Class 139.] In an indicating device for attachment to a clock comprising one or more manually adjustable pointers to indicate when a predetermined time has elapsed (e.g. in a cooking operation), the pointers are mounted on a member adapted to embrace the clock casing and to be adjustable to fit clocks of various sizes. The collar 11 has a section as shown in Fig. 2 for receiving adjustable pointers 12, 13 on its bead 11<1> and is clamped to the clock case 5 by the screw and nut 17, 18.

Abstract: 597,026. Electrical calculating- apparatus. GENERAL ELECTRIC CO., Ltd., SNOW, P. E. ACKLAND-, FARREN, L. I., and RIVLIN, R. S. Sept. 24, 1941, Nos. 12371 and 13625. [Class 106 (i)] [Also in Group XXXVIII] Electrical calculating-apparatus for obtaining the time-derivative of a function or for use in predicting apparatus comprises a magnetic tape 1 moved at constant speed along a definite path, means for magnetizing the tape at one point and pick-up means 3, 4 energized by the tape, and means for combining the outputs of the pick-up means, possibly with the input of the apparatus. As shown, an alternating voltage of constant frequency with an amplitude proportional to x(t), a function varying with time, is applied to an electromagnet 2 to magnetize a steel tape. At times t+t1, t+t2 this point of the tape passes pick-ups 3, 4 so that at time t the pick-ups generate voltages proportional to x(t - t,), x(t - t2). These voltages may be differenced and if t2 - t1 is sufficiently small, the output is proportional to dx/dt. By using a number of steel tapes in succession, further time derivatives may be obtained. By making t2 - t1 large, with suitable amplification and rectification of the input and two outputs, a combined direct voltage V may be obtained proportional to x(t+T3), i.e., the predicted value of x after a further interval of time T3, where adjustment may be made on potentiometers in the amplifiers 5, 6, 7 for the desired value of T3. Pick-up 3 and amplifier 6 may be omitted. Instead of using alternating voltages of variable amplitude, alternating voltages of varying frequency may be used for the determination of dx/dt, which is obtained by the difference of the output frequencies. After passing pick-up 4, the tape is de-magnetized by known means.

When in the clutched position the bevel-wheel 30 is out of engagemen with the bevel-wheel 15 and the whole mechanism revolves as one. When adjustment is required the sleeve 11 is braked, thereby bringing the sleeve 10 to rest, the bevel-wheel 30 is engaged with the bevel-wheel 15, and rotational move ment of the shaft 29 is transmitted through the planet-wheels and produces rotation of the sleeve 9 relative to the body 5, thus clutching or un clutching according to the direction of rotatior of the shaft 29. The sleeves 10, 11 may be locked together after adjustment.
