Title: Sewing machine having a device for initiating the movement of the thread catcher of a thread cutting device
IPC: D05B65/00
Filed: 1977-07-13
Abstract: The sewing machine includes a reciprocating needle bar with a thread-engaging needle which cooperates with a rotatable looper carrying the looper thread which is driven by a rotatable looper drive shaft. The construction includes a thread knife and a thread clamp mounted adjacent the looper and a catcher mounted on a catcher shaft for rotation therewith selectively in the same direction of movement as the looper toward engagement with the knife and in an opposite return direction. The construction includes an improved control member for operating the catcher which is freely rotatable on the looper shaft and is axially displaceable therealong between an operative position and an inoperative position spaced axially from the operative position. A coupler is provided between the control member and the looper shaft which includes a driver having a rod portion which extends in a groove of the control member. A biasing spring biases the control member into an operative position. A stud abutment is mounted to move toward and away from a control member between a starting and an operative position and may be locked in the starting position. The stud abutment is engageable with a cam portion of the control member and the cam portion acts to return the stud abutment to a starting position. A retaining member is located adjacent the control member and it is mounted so that it can be biased by a spring associated therewith to hold the control member in an operative position.

Patent ES-467392-A1 (ES)
Title: Address and break signal generator
IPC: G06F13/00
Filed: 1978-02-28
Abstract: Two asynchronously operating computers which are each controlled by timing periods produced by its own clock are each provided with a pulse treatment circuit which in response to a break signal, interrupts the computer operation during the following timing period. A buffer memory is used in order to transfer information from the first to the second of the computers. Because of the asynchronism there is a risk that the buffer memory becomes either totally occupied or unoccupied. The risk is eliminated by means of an address and break signal generator which generates addresses to control writing and reading of the buffer memory and generates break signals which are sent to the pulse treatment circuit of the first and second computer in order to inhibit information from being sent to the buffer memory when it is full or drawn from the buffer memory when it is empty. The writing and reading addresses are generated by means of a first and a second circulating address counter stepped by the pulse treatment circuit of the first and second computer, respectively. The break signals are generated by means of a comparator connected to the two address counters. In addition the timing periods of the operating cycles have portions during which the computer components work unreliably due to their reaction times i.e., the setting of flip-flops, the ripple in counters, etc. Therefore, a reliability device compares the phases of the timing periods produced by the two computer clocks in order to allow only break signals which are generated owing to the comparison of addresses obtained in period parts during which both address counters are reliable.
