Title: Improvements in or relating to means for attaining synchronism between independently driven endless chains or the like
Inventor: BURROWS ARTHUR THOMAS CHARLES
IPC: B65G23/28
Filed: 1956-03-27
Abstract: 800,747. Controlling variable-speed gearing. KING, Ltd., G. W. March 11, 1957 [March 27, 1956], No. 9557/56. Class 80 (2). [Also in Group XXX] On a means for attaining synchronism between two independently driven members, the members are coupled to a common epicyclic gear assembly such that difference in their speed of rotation results in an angular movement of a member of the gear assembly which is coupled to a variable-speed gear incorporated in the drive to one member, thereby varying the drive and synchronizing it with the other member. 10, 11 are two independently-driven conveyer belts, 10 being driven by a motor 13 through the variable-speed gear 14 and a gear-box 15. The drive to 11 is not shown. A gear-wheel 21 on the drive shaft 19 of the conveyer belt 10 is meshed with external teeth on the annulus 22 of an epicyclic gear assembly and the drive-shaft of the conveyer belt 11 is coupled to the sun-wheel 28 by a chain 25. The planet-wheels 29 are freely mounted on a planet carrier 30 which has a chain sprocket 31 secured thereto and connected by a chain 32 to the control shaft 34 of the variable-speed gear 14. If the speed of drive of the members 10, 11 is equal the planet carrier 30 will not rotate. Any variation in speed between the members will cause the planet carrier to rotate and apply a correction to the variable speed gear 14 to synchronize the members. A dashpot 35, 36 prevents hunting. The chain drives may be replaced by gear trains or by drive connection and the link between the planet carrier and the variable-speed gear may be by rack-and-pinion.

An injection moulding machine has a storage arrangement for. measurement or operating valves comprising an integrated switch element store coupled through a logic circuit to input and output devices. As shown the output of a transmitter 9, producing a pulse for each unit of angular movement of a machine part or member coupled thereto, of an injection moulding machine, is fed through a pulse evaluator 10 to a forwards/backward counter 11, the instantaneous contents of which is a measure of the actual travel. The counter 11 is connected, by a setting switch 6, to feed a digital store, formed of integrated switching circuits, via a logic circuit 2 which is controlled by a manual, or machine-operated selecting switch 7, having positions corresponding to modes of operating the machine. Further information is fed to the store 1 by a decade switch 5. A switch 8 governs the mode of operation of the storage arrangement and when this switch is in the setting mode the counter 11 is connected through the logic circuit 2 to a particular storage location of the store 1 and when the machine part has attained a desired position the contents of the counter 11 is read, by operation of switch 6 into the storage location and the next storage location selected by operation of switch 7. On selection of semi-automatic or automatic operation the logic circuit 2 is rendered inoperative and a logic circuit 3, connected to the store 1, rendered operative whereby the contents of the storage locations are presented to corresponding AND-gates 4. The counter 11 is also coupled to the logic circuit and when the value in the counter corresponds to the content of the appropriate storage location a control signal is applied to the machine from the respective AND- gate 4, the signal lasting until it is terminated by an order derived from the next storage location. During setting, the contents of the selected storage location is displayed, through a code converter 12, on a digital electronic indicator 13 and, during operation, the reading of the counter 11 is indicated. It is stated that times, temperatures and pressures may be similarly introduced into the storage locations and used for control of the machine.

Abstract: PURPOSE:To improve the senses of sight and hearing by detecting a false frequency ratio with a ratio detecting means and generating a ratio detection output signal in response to this detection and transmitting the generated ratio detection output signal. CONSTITUTION:Each raw feature sensor 210 decides whether there are features belonging to its range or not. The range of the raw feature sensor 210 is divided by a certain exponent value, and this exponent value is so selected that approximating calculation of a low integer ratio or other important ratios is facilitated. A ratio detecting network 416 responds to raw feature sensors 210 and compares each pair of results from raw feature sensors 210 with each other and collects comparison values related to a specific ratio to obtain a series of signal outputs, thereby detecting the specific ratio of raw feature data. A ratio detection network output signal bus 426 transmits a signal indicating that the specific ratio exists in false frequencies detected by raw feature sensors 210. Thus, visual and audio input feature recognition is improved.
