Title: Bowling Game Scoring Apparatus
IPC: A63D5/04
Filed: 1966-10-12
Abstract: 1,162,713. Bowling alleys. BRUNSWICK CORP. 12 Oct., 1966 [14 Oct., 1965], No. 45642/66. Heading A6D. In an apparatus for scoring splits occurring in a bowling, game pin setters provided with sets of pin detector switches, Fig. 1 are employed and score information is transmitted through a cable to a summer SSD which translates the signals into a single mechanical signal for each ball pincount. The mechanical signal is fed to a mechanical computation unit C where scores are computed and entered into appropriate memories. The computer controls a printer for printing the scores. The scoring system includes a split detector providing a signal derived from an input of specifically identified pins standing or fallen and where appropriate prepares the printer for printing a split designation with the scores. The summer operates by changing the length cf a mechanical linkage with the computation unit one unit responsive to each pin detector switch which remains closed after a pin detection cycle. Individual signals identifying the portion of each pin down are received by the sumrner and are compared by the split detector with a set of known pinfall combinations in which a split cannot occur. Fig. 3 shows the split detector 601 in which portions of slide bars, one for each pin, extending from the summer have highs 602 and tows 603, Fig. 8, which move into or out of alignment with each other depending on the movement of the slide bars during the summing procedure. A feeler system is provided to detect the presence of split conditions from the presence of highs on the slide bars. The application of the apparatus to the scoring system of United States of America Specification 3,435,120 is described together with the use of the projection apparatus of United States of America Specification 3,269,259 for projecting the image of the scoresheet on a viewing screen.

Title: Improvements in or relating to electric pulse rate meters

IPC: G01R23/09
Filed: 1961-12-20
Abstract: 963,758. Frequency detectors. S. SMITH & SONS (ENGLAND) Ltd. Jan. 18, 1963 [Dec. 20, 1961], No. 45738/61. Heading H3A. An input pulse train is applied over 9, 10 (Fig. 1) to an emitter follower connected junction transistor 1 whose output across resistor 12 is connected to the base of junction transistor 2, whose collector supplied over resistor 15 is connected over resistor 14 to the base of junction transistor 3 having its collector supplied over resistors 16, 17 and its emitter connected to earth line 7 over resistor 16 in common with the emitter of transistor 2. A capacitance shunted meter 4 in series with resistor 18 and rectifier 6 is connected between the emitter of 2 and the junction of 16, 17, while a Zener diode 15 is connected between the collector of 2 and the junction of 18 and 6. When transistor 1 is cut off with its base at earth potential, transistor 2 is similarly cut off and its collector and the base of transistor 3 are held negative so that the latter conducts and the junction of 16, 17 is held negative relatively to the collector of transistor 2 and rectifier 6 is non-conductive. Application of a negative pulse to transistor 1 causes it to conduct and negatively pulses the base of transistor 2, which conducts so that the base of transistor 3 becomes less negative, and the transistor ceases to conduct, assisted by positive feedback over resistor 13. The collector of 2 becomes positive with regard to the junction of 16, 17 to a degree exceeding the critical voltage of Zener diode 5, so that rectifier 6 and Zener diode 5<1> conduct to maintain a fixed potential across meter 4 and resistor 18, so that a constant meter current flows so long as the voltage across meter 4, Zener diode 5<1>, and rectifier 6 exceeds the critical Zener voltage. On cessation of the negative pulse on the base of 1, the transistors all return to normal and rectifier 6 becomes non-conductive. For a pulse train of constant duration and adequate amplitude on 9, 10 the average meter current is proportional to pulse frequency and capacitor 19 maintains a steady reading. In a modification (Fig. 2), a resistor 24 is inserted between the emitter of 2 and resistor 13, and the emitter of 2 is returned to the resistor junction, while resistor 25 is returned to earth from the base of transistor 3, ensuring that transistor 3 is cut off on application of negative pulse to the base of transistor 1. The cathode of Zener diode 5 is returned to earth, while its anode is connected to the base of silicon transistor 20 and to the supply line 8 over resistor 23. The transistor emitter is connected to meter 4 over resistor 18 while the collector is connected to the anode of rectifier 16<1>. Zener diode 5 always conducts at its Zener point, while rectifier 6 and transistor 20 are non- conductive in absence of a negative pulse at terminal 9, but conduct in a negative pulse to pass current through meter 4. A fixed potential is maintained across meter 4 and rectifier 18 in series.
